Written about us – an article in the Forbes magazine

Our activities in the field of PT preference began on the classic  radio path  in 2021. Later in 2015, we began our search for a general ES and PT vehicle preference that does not depend on “Herman” technology. Choosing  preference using V2X  communication (European standard ITS) was the logical conclusion. This solution was  recognized by Forbes in an article about our activities in this field. You can read it  here. The article concentrates on the utilization of the V2X technology in Brno and not only there.

Über uns geschrieben – Artikel im Forbes-Magazin

Unsere langjährige Tätigkeit im Bereich ÖPNV-Bevorrechtigung begann in 2012 mit der klassischen Funktechnologie (eine Firmenspezifische Lösung) und später ab Ende 2015 suchten wir nach einer allgenmeinen Lösung für integrierte Rettungssysteme und ÖPNV-Fahrzeuge, die unabhängig vom „Herman ” Technologie ist. Diese Lösung wurde dann im Forbes-Magazin ausgezeichnet, das einen Artikel über diesen Tätigkeitsbereich des Unternehmens verfasste. Sie können seinen Inhalt hier einsehen. Der Artikel beschreibt hauptsächlich die Anwendung dieser V2X-Technologie in der Stadt Brünn, jedoch nicht nur hier.

Providing preference to first response FRS vehicles in Brno

At the turn of 2020/2021, we finished the installation of  C-ITS units  UCU 5.0V  in 13 vehicles of the FRS of South Moravia Region (we supplied the FRS with 15 units altogether). They provide preference of first response vehicles (e.g. fire engines, command vehicles, rescue vehicles, and ladder platform vehicles, etc.)  using V2X communication at chosen intersections in Brno. UCU units meet the latest C-ITS system requirements and they use secure communication in PKI C-ROADS. This finished one of the phases of our long-term cooperation with the FRS of South Moravia Region that began with a test run (more info here) in 2017. The new system will ensure that FRS vehicles will arrive in a quicker and safer way and thus it will increase the security of the citizens of Brno and the South Moravia Region.

Ausstattung der Präferenzen der Erstlinie Feuerwehren in der Stadt Brünn

Zum Jahreswechsel 2020/2021 haben wir die Installation von C-ITS-Einheiten des Typs UCU 5.0V in 13 Fahrzeugen der Feuerwehr in Südmähren abgeschlossen. Diese stellen die Bevorrechtigung von Erstlinie-Feuerwehrfahrzeugen (z. B. Panzerspritzen, Kommandowagen, Rettungsfahrzeuge und Autoleitern usw.) an ausgewählten Kreuzungen in Brünn mit der V2X-Kommunikation sicher. Die UCU-Einheiten erfüllen die neuesten Anforderungen für C-ITS-Systeme und verwenden eine sichere Kommunikation in Sicherheitsinfrastruktur (PKI) von C-ROADS. Mit dieser Lieferung und Inbetriebnahme des Systems wurde eine Etappe unserer langjährigen Zusammenarbeit mit Feuerwehr der Region Südmähren, die 2017 mit dem Testbetrieb begann, abgeschlossen (mehr lesen). Das neue System wird eine sicherere und schnellere Durchfahrt der Feuerwehrfahrzeuge zum Einsatzort gewährleisten und somit die Sicherheit der Einwohner von Brünn und der Region Südmähren erhöhen.

Trial run of EMS and PT vehicle preference in Ústí nad Labem

Since October 2020, a trial run of EMS vehicles (emergency medical services) of the Usti nad Labem region has been underway in Ústí nad Labem. We cooperate with the NTD company and together we have equipped 2 ambulance vehicles with  OBU units  and 2 intersections using Cross controller units with our RSU units.  Just like in the case of the FRS in Brno , V2X communication is secured and the certificates that are used are accepted on the European level. This prevents any unauthorized use. Hybrid communication ensures reliability i.e. preference messages travel via both V2X communication and LTE connection. 2 vehicles of the  Ústí nad Labem Transportation company have been included in the preference system.

RSU units also use a signal plan of an intersection controller unit which means that any vehicle with V2X can accept this signal plan. This V2X trial run offers a complete set of usable urban C-ITS services.  You can read more here.

Pilotbetrieb der Präferenz von Rettungswagen und öffentlichen Verkehrsmitteln in der Stadt Ústí nad Labem

Seit Oktober 2020 ist in Ústí nad Labem ein Testeinsatz der bevorzugten Rettungsfahrzeuge der Region Ústí nad Labem (Rettungsdienst) im Einsatz. Hier haben wir in Kooperation mit der Firma NTD zwei Ambulanzfahrzeuge mit unseren OBUs und 2 Kreuzungen, die mit LSA-Steuergeräten der Firma Cross ausgerüstet sind, mit unseren RSUs versuchsweise ausgestattet. Wie bei der Feuerwehr in der Stadt Brünn ist auch hier die V2X-Kommunikation abgesichert und die verwendeten Zertifikate auf europäischer Ebene anerkannt sind. Dies verhindert unbefugten Missbrauch. Eine hohe Zuverlässigkeit wird durch die hybride Kommunikation gewährleistet, d.h. Präferenznachrichten gehen sowohl über die V2X-Kommunikation als auch über die LTE-Verbindung. Neu am Präferenzsystem sind auch 2 Fahrzeuge des Verkehrsunternehmens der Stadt Ústí nad Labem beteiligt.

Der Vollständigkeit halber senden die RSUs auch einen LSA-Signalplan, sodass alle V2X-Fahrzeuge diesen Signalplan empfangen können. Der Pilotbetrieb des V2x-Systems bietet somit einen kompletten Satz an heute nutzbaren City-C-ITS-Diensten (mehr lesen).

PT Preference using V2X and IBIS-IP in Ludwigsburg

In Ludwigsburg, Germany (Baden-Württemberg), we successfully tested  public transportation preference using V2X communication. Our OBU unit – version UCU 5.0 LWVG  was installed into a Man bus belonging to the  LVL-Jäger company. The unit was connected to an on-board computer from IVU Traffic and the IBIS-IP standard was used to facilitate communication between these devices. The unit used route and destination information to provide vehicle preference by sending a CAM message containing preference data in the R09.16 format. The test was performed with a reference receiver RSU unit at an intersection controller from Swarco.

Our UCU 5.0 units  have proven again that they meet international standards and that they can be adapted to various operation conditions. Successful tests (description here)  have cleared the way for us to supply 100 pieces of these units to this company.

ON-LINE connection search engine with direct ticket sales in PP

The passenger transfer regime in regional public transportation makes it possible for passengers to buy tickets with multiple transfers and to choose from multiple routes. Drivers can provide this by searching for a connection ON-LINE, choosing a connection and selling the ticket. The EPIS 5.0A   on-board computer  has been equipped with an  ON-LINE connection search engine . This function is connected with direct ticket sales including printing of a found connection information slip.  This function makes the above described situation easier for both passengers and drivers, and it also ensures that the ticket price is correct. The Herman company has proven its technological lead yet again when this function was integrated into the EPIS 5.0A on-board computer.

New generation of vehicle LCD

We prepared a new generation of vehicle LCD with a new generation of control PC and a new HW arrangement. The new LCDs use SSD drives with a minimum capacity of 32 GB, their startup time is much shorter, they can store long video sequences, and advertisement or transport campaigns can be loaded in advance and recognized by their validity. They can work with foreign protocols (an example of cooperation with a Transdata on-board computer) or they can work with the latest version of our universal protocol EPISNET.

Mery Christmas and Happy New Year 2021

We wish everybody happy holidays and success in 2021 even in these complicated times. We would like to thank our customers for their interest in our products and services. In 2020, we not only worked on our “usual“ orders but we also worked on some important projects. One of the projects was a new type of   EPIS 5.0A on-board computer with checking  (1000 pieces for IDS JMK) and Backoffice BOS  to manage it. We made progress in integrating V2X communication systems and we integrated PT and ES vehicle preference  including  tram collision prevention. We developed a stop sign with electronic paper  (e-link), solar power supply and a new control server. The last project was a “traffic island camera system” for public transportation vehicles including a supervision server with online recording downloads. In 2021, we plan to introduce innovations in the field of on-board computers and communication units and to further develop SW BOS and Sprinter.

Independent vehicle camera system with remote supervision

We prepared a new type of vehicle camera system  EPIS 5.0KS . It is not dependent on vehicle electronics (optional). The system is based on  EPIS 5.A,  or more precisely  EPIS 5.0KS  on-board computer. Up to 16 cameras can be connected to the recording system. The “on-board“ camera computer is equipped with 2x SSD (control and record keeping), LTE, GNSS and WIFI modules and a high performance four-core PC. As it has its own SIM card, it is possible to supervise its state and to download recordings online at any time. It is controlled by the latest version of the BOS – KS system.   A special 8 button OV-01 unit is used to operate it from a vehicle. It also includes an   ECU 08LM.7T  ethernet switch with PoE as per IEEE 802.11 at. This innovation adds a  traffic island camera system to our portfolio.

New type of stop sign with e-paper and a solar panel

We developed a new type of stop sign with e-paper  ELP 191. It is powered by solar panels and it does not need the  230V net power supply or overhead line power supply. It is equipped with an  LCD display with e-paper. It can be placed anywhere where the sun shines – you just need to build the needed foundation.

The panel uses brand new control unit technologies, it works with  lithium accumulators  (BMS system), it uses a new type of  low consumption command receiver for the vision impaired (EPNEV 1.24)  and it can control the charging of the accumulators by the solar panels. E-paper illumination is controlled by a contactless capacity button. The consumption of the panel is about 50-70 mW. An LTE modem is used to connect to a server. We also developed a new way of panel control using a new type of control server.

Tests of compatibility of our V2X units with Volkswagen Golf

Picture of V2X functionality from the Volswagen magazine where the tests are described. The picture shows how a car communicates with signs warning about traffic change.
Together with the Czech representation of Volkswagen we tested the compatibility of the V2X technology (also Car2x) used by the new VW Golf, and by our units UCU and RSU. Volkswagen Golf is the first line produced car that includes V2X in its equipment and which could use all the services provided by our units that were utilized e.g. in EU during the C-RODAS and the RIS II project. In the course of 14 test days, we tested VW Golf broadcasting in various traffic situations . It was confirmed that our systems broadcast as per the same norms and with the same content as VW Golf. VW Golf, like our units, uses the latest security standards. However, it turned out that the only compatibility issue is security related. Logically, Golf does not trust Czech certificates and therefore all Czech messages also generated during th C-ROADS project are deemed untrusted and ignored. According to a Volkswagen statement, the company has to protect its customers and therefore does not trust the pilot C-RODAS certificates. You can read an interview with our colleague specializing in this technology and about the tests themselves in the Volkswagen magazine.

Communication protocol EPISNET for controlling LCD

Our LCD – type VCS 185AE-JMK, the first to use this extened protocol for IDS JMK. The picture shows an example of a bus drive when one line changes into another.
We introduced a new version of communication protocol for controlling LCD – EPISNET version 1.42 (and not only for LCD). This protocol expands LCD control used in transportation vehicles in the Czech Republic. It is used by DPO a.s. and DSZO and it has also been implemented in vehicles managed by the South Moravian Region Coordinator Kordis JMK a.s. and in vehicles of DPMB a.s. (almost 2500 vehicles in total) now also including remote updates. The protocol also includes the function of receiving dispatching messages and messages from traffic closures and assigning this messages to individual stops, it further includes dynamic signs in vehicles – so called virtual ELP, overview of connections at stops, and other functions. There is a special function of displaying the route of „vehicles“ that „change“ multiple times during one drive i.e. they go through multiple lines in a sequence without passengers having to transfer. „Graphic manuals“ are created for this protocol that describe how an LCD in a vehicle is to behave to meet all the requirements of the vehicle operator. This is a highly advanced protocol with diverse utilization.

First integrated preference of ES and PT using V2X

During the all European project C-ROADS, we put a vehicle-crossrad communication system into operation that is able to provide preference of not only PT (public transport) (supplied during the RIS II project) but also ES (emergency services) and the fire brigade in one unified V2X communication system. This is a unique solution. Its functionality was verified during C-ITS interoperability tests in Brno on 20.5.2020. The tests were a part of the C-ROADS projects and other suppliers were also involved.
In over a year of operation, the new PT preference solution based on the V2X standard has proven itself useful to the full extent in Brno (Czech Republic). The units that use this solution to communicate with other units include 750 UCU 5.0 units in PT vehicles, a few OBU units (on-board units – UCU 5.0) used by the fire brigade and 93 of our RSU at intersections (12x for C-ROADS and 81x for DPMB). It has been confirmed that this is the first and the biggest „for real“ utilization of V2X in Europe and mainly in PT.

Sorry, TRANS IT exhibition has been postponed indefinitely because of the Coronavirus

SW SPRINTER helps to manage the transport of the Ústí Region

The Ústí nad Labem Region officially introduced a new dispatching center for the Ústí nad Labem Region based on our SPRINTER control dispatching software on 2020 February 26.  SW is running on our remote servers. The dispatching center provides  the opportunity for passengers and the public using the light client of our SPRINTER SW to see on the map the online location of all buses and trains.  It also provides data via the SPRINTER API for the virtual departure boards of each stop, where real vehicle departure data is displayed. The dispatching center displays 100 trains and approximately 400 buses, while the city public transport is being prepared.

Cameras in vehicles increase security and lower costs

Vehicle cameras can record events in vehicles (camera systems) and they can be integrated into vehicle information systems (integration description here). Vehicle camera shots can be transferred directly to the dispatching (e.g. by using router UCU 5.0) to display events in the vehicle (e.g. in the dispatching control SW SPRINTER). An example of on-line display from  front cameras at the dispatching can be seen on the adjacent picture, they can be used not only to assess events during a collision but also to check the situation on lines and at stops. On-line display can supplement many control rides from the dispatching – you just need to wait for the vehicle to go by and check what you need. It is faster and cheaper. Realized as a part of the RIS II project.

Communication using V2X can prevent tram collisions

The result of stopping a tram going 30 km/h after collision alert. The vehicle stopped really close to the position of a simulated tram standing in the front – marked by cones.

On 13. 12. 2019, our company tested an algorithm that warns the driver about an impending tram collision (crashing into a tram standing in the front). This test was undertaken in cooperation with the CTU (department of Control Engineering) and the Transport company Ostrava plc.. The algorithm is based on communicatiuon as per the V2X (ITS G5) standard where vehicles exchange information about their position and state.

A Vario LF2 tram belonging to the Transportation company Ostrava (DPO a.s.) was used for the test which took place in a depot in Poruba. The impending collision warning for the driver was provided by our communication units UCU-5.0V equipped with modules as per the V2X (C2X) standard that are run in DPO plc.. It was a test of a functionality implemented in the tram communication unit. Press release here. With the system applied in practice it would be possible to prevent this recent tram collision in Pohořelec, Prague.

Another useful V2X communication function is public transportation vehicle preference (described here) including statistical results from a very busy intersection in Brno.

Successful Plugtest of V2X units in France

On 4.11 – 7.11 2019 our company participated in ETSI CMS7 Plugtes in Nice, France. This Plugtest was an international event held by the European Telecommunications Standards Institute to test and tune the compatibility of V2X communication among individual manufacturers. Plugtest concentrated on the security of V2X communication and it was held directly on the ETSI premises. The ability of V2X units by individual manufacturers (in our case units UCU 5.0-x) to exchange messages in a secure form was tested i.e. Whether they are able to validate digital signatures in the communicated messages and whether the messages are in the form set by the norms issued by ETSI. The suppliers of the central security features i.e. PKI structures (Public Key Infrastructure) also participated to ensure credibility of the signatures. The tests proved the compatibility of the communication solution of our units UCU 5.0 with the units by other manufactures via V2X as well as of communication UCU unit – PKI via the HTTP protocol (acquiring the certificates of validation of credibility of message signatures).

BOS is starting – New Generation BackOffice System

BOS (BackOffice System) is a multi-user strictly modular server application for preparing and processing data not only form checking. It is also designed to manage vehicles, V2X units and WiFi, it makes up the basis of a data cube etc. It is built on the client – server principle for Windows and it follows our  I. and II. generation of single-user backoffice. It is based on our new core of server applications COMPASS. BackOffice BOS – now mainly directed at checking and vehicle management – contains these basic modules

• user and user right management
• individual carrier management
• vehicle and vehicle equipment management
• checking management (tariffs, ticket creation, price lists, deductions, transactions and their export)
• schedule management (editing, import export)
• and others ….

A more detailed description is being prepared.

• New type of course indicator VLP 0835Y and VLP 0835W (orange and white versions)
• Vehicle LED and LCD information panels
• And other products from out assortment …

New on-board computer with checking – EPIS 5A

The new type of line 5 on-board computers with checking – EPIS 5A is manufactured in a number of versions.  There is a single-board version with an integrated PC computer (up to 4 cores, up to 4 GB RAM, SSD from 16 GB), an LTE modem and a Wifi module IEEE 802.11 ca. The computer is “dockable” and has an auxiliary accumulator. It is equipped with a full acoustic set – digital switchboard and 3x amplifier (inside and outside the vehicle and for the driver – including an integrated speaker). The EPP 5.0 passenger checking unit can be connected to the on-board computer. The on-board computer can interface with the UN 30 intelligent external power supply unit that turns on vehicle information systems as needed. Modern interfaces are a standard – Ethernet 1 BG/s or USB 3. The on-board computer can simultaneously communicate with a dispatching server (SPRINTER) and a checking, data and computer maintenance server (CBO – a new backoffice product for processing transactions, it is designed for regional PT ).

It can be connected with the EPT 4.10 10,2″ wide screen high illumination display with 1200×800 point resolution, resistant touchscreen, integrated microphone and auxiliary illuminated keyboard.

Integration of functions of EPIS on-board computers is underway

A new and very important function of the EPIS on-board computer  version EPIS 4.0C4 (a hybrid of the on-board computers used by DPMB plc., DPO plc. and PMDP plc.) is the ability to provide voice communication not only by using a radio network but also by using fast data networks GSM – LTE/UMTS. This new type provides communication outside the reach of radio networks by using “data tariffs” on SIM cards. Integrating the SIP protocol into the dispatching control system SPRINTER  and into EPIS on-board computers together with using their sound cards provide selective calls, group calls and even group talks (multiple participants or on-board computers can communicate simultaneously). GSM communication can be integrated in the EPIS 4.0C5 on-board computer or an external modem EPG 4.0L or UCU 4,0x or UCU 5.0x unit can be used.

PF 2019

We wish everybody nice Christmas holiday and a lot of success in 2019. This year was probably the most demanding in the history of our company. Not only did it bring the highest production and  supply of about 4.5 million EUR but also many new technological solutions which are being introduced to you gradually. The solution of the key project “Control and information system for public transportation – RIS II’ for DPMB plc. employed more than 100 people at the time of installations. The difficulty of this project caused delays in SW supplies for which we would like to apologize to our customers. In the coming year, we are going to implement some changes in the company organization and we believe that the situation will improve.

New course indicator – VLP 0835

The new conception of the VLP 08×35 course indicator is able to display 6-digit line and course indications including displaying numbers. The spacing of the LED diodes of the course indicator is 6 mm and it is readable from the distance of about 25 m.

It is equipped with special brightness control based on surrounding light and resistant to reflections from outer glass. It can be connected by Ethernet interface with PoE, RS 485 or IBIS. The color is at a request (white, yellow, …) and there is a wide variety of anchor options.

New unit for counting passengers – UCP-02

We developed a new unit for counting passengers UCP-02. This unit meets the high demands on the accuracy of counting with the accuracy of more than 98%. This was achieved by providing the unit with computing performance 10x higher than that of the UCP-01 unit (no longer supported). This allows the unit to make a high number of photos for more precise scene comparison.

At the same time, a number of new mechanics for anchoring in municipal and regional PT vehicles were developed. The new unit is only powered by one UTP cable with type B PoE system using power from our Ethernet switches ECU 08Px.

The system is again tied to the  evaluation program ADA and to on-board computers EPIS, or it can be used independently.

Communication units for Ethernet

We offer a line of 8-port Ethernet busbar switches which are based on non-controlled Ethernet switches and their outputs are controlled in various ways by the control processor:

1. ECU P0 – PoE +24V, or 12V type B (e.g. for APC)
2. ECU P1 – PoE +24V with output IBIS (converter ETH/IBIS)
3. ECU P2 – has a converter to 48V and PoE type B
4. ECU P3 – has converter as per IEEE802.11F (PoE for powering the front camera and ports +24V type B (powering the course indicator, etc.)

Other types were developed as well– ECU 05.2L and ECU 08.1F.

New assembly line for fitting SMT parts

We acquired a new complete assembly line for mounting SMT parts which provides functions from automatic application of solder paste, a new mounting machine to a new soldering machine with vapor phase soldering. With this new line we doubled our capacity of fiting printed circuitboards to more than 30 thousand part per hour. This was neccessary for us to be able to perform difficult production tasks. Unfortunatelly, we received the assembly line with a delay which has been causing supply issues. We also intorduced opticak inspection of production to uncover soldering and fiting errors.

International exhibition InnoTrans 2018 in Berlin

Successfull particiation in international Intercor Testfest

During the last week, from April 23 to April 26, we successfully participated in the Intercor PKI Testfest, which took place in the city of Reims, France. The goal of the event was to test an internation interoperability of V2X services in terms of security. This was the first public and open security test in Europe. Teams from 11 states participated in this event and brought 22 On-Board Units (OBUs) and 12 Road-Side Units (RSUs).  The participants were mainly the partners of the Intercor project, but other teams companies joined as well, in total 19 companies (including Renault and Peugeot).

The event was divided into 6 scenarios, which were tested one after another. Our team, as one of only three companies, succeeded in all of them. Each scenario tested a certian aspect of a secured V2X communication, mainly the way the certificates are exchanged and the conditions, under which the messages should be verified and under which they are valid

The test consisted in rinding a given 23 kilometer long circuit, which led through highways and also through city roads. There were 4 RSUs of the French road operator SANEF. These RSUs sent warning about non-standard situations using DENM messages (e.g., road-works warning, string wind, slow vehicle). The mesages were also sent from the SANEF vehicles (V2V), such as human on the road and stationary vehicle.

More about the event is written in the article “International tests of interoperability in V2X communication”

The new on-board computer EPIS 4.0C.

We finished the development of the EPIS 4.0C on-board computer that satisfies the new demands on this type of device. It is built on the 64 bit architecture, DDR3 memory, fast SSD discs, 1 Gbit/s Ethernet, USB 3, radio communication interface for analog, data or TETRA radio stations. The PC architecture ensures stable development of SW in the years to come. Its performance is 10x better than EPIS 4.0A or EPIS 4.0B and up to 100x better than the first type while being mechanically, connector-wise and SW-wise interchangeable with them. This shows us that the original conception of on-board computers was correct.  To get more details about the demands on the new generation of on-board computers see the article here.

Transformation to Herman systems Ltd. and new premises

We started a transformation of the form of the company from a natural person to a legal person -Herman systems Ltd. Considering the place of the company on the market, this is a logical step that ensures future continuity of the company. However the process is going to be long and complex. During the long-lasting history of the Ing. Ivo Herman, CSc. company, commitments and liabilities have been established that cannot be changed in a day. This also applies to the law and tax aspects of the transformation.

We are also opening new primarily development premises of the company on the upper floor of the company building and in two extensions of the building. The overall space increase is about 1000 m2 and we invested more than 18 mil. Czech crowns in this reconstruction.  We could not expand our company without this investment.

Realization of the transportation terminal in Bratislava

We provided complete outer information LCD display equipment for the substitute bus terminal in Bratislava near the Mlýnské Nivy street. This included 34 pieces of 32″ outer LCDs ELP 832A that are placed at each platform and display current departures. It also included 12 pieces of 55″ LCDs – type ELP 855A used as overview displays when going through the platforms. Two of these panels are always connected opposite each other creating a double-sided LCD set. One 65″ LCD – type ELP 865A was also included. It is going to be used as an orientation display and it’ll be installed standing (its anchor is being prepared). All LCDs are supplied in the new SLIM rendering (thin edges) with high illumination LCD displays min. 1000 Cd/m2, antivandal rendering and they are equipped with antiglare glass (antireflection). The LCD panels are equipped with display SW using the design by the Transdata company that supplied the control SW for the terminal. The panels are autonomous and they download departure data from the control server of the terminal.

Realization of the transportation terminal in Bánská Bystrice

In just under three months we managed to prepare a new type of departure double-sided stop panel ELP 225B for the newly constructed transportation terminal in Bánská Bystryce (more about the terminal here). The panel is characterized by an illuminated platform number (e.g. yellow – inter-city transportation, blue – suburban transportation, red – municipal transportation), a graphic LED surface for displaying bus departures, and a white time display. The supply also included information LCDs  ELP 865A in the antivandal rendering and new SW Sprinter modified for transportation terminal control. The supply of 20 departure panels ELP 225B, 8x LCD 65″ in the antivandal rendering and the SW SPRINTER TERMINAL was produced and put into operation in just under 80 days including new mechanical solutions.

New type of vehicle communication – V2X (C2X) is coming …..

Our company has become one of the producers of units supporting the V2X (or C2X) communication. It is a vehicle-vehicle or vehicle-infrastructure communication based on the European standard ETSI ITS G5 and on the frequency of 5,9 GHz. This communication unifies the communication of a vehicle with its surroundings, i.e. both with other vehicles and with the infrastructure (intersection control units, intelligent signs, notifications sent to vehicles – e.g. to the EPIS on-board computers, communication with intelligent stop signs, manual or automatic throwing of switches, etc.). Both HW and SW components are fully controlled by our company which means that we can perform modifications on a request and supply custom solutions. These new V2X units unify our long-lasting efforts to create a unified vehicle communication device for medium distances that would broadcast the system state to the surroundings. We are preparing both a solution for vehicles (car unit) and a solution for stationary devices (RSU). These units will gradually become a standard in all motor vehicles and not only them. More information about the new units and systems will be published.

Renovation of some of the outer LCDs of the terminal Svinovské mosty

We performed a repair and renovation of some of the outer LCDs of the transportation terminal Svinov where the large overview 55″ LCD panels (type ELP A855 EH) were damaged by a passing vehicle. Small stop LCD panels were insufficient for displaying departures which is the reason why double LCDs (type ELP D821EH) were rebuilt into triple LCDs (type ELP F821EH) while departures were divided between the individual LCDs based on the traction and transportation type. The front protective glass was replaced and the “antiglare” technology was used. This important technological innovation reduced unwanted reflections coming from the surroundings.

Self-service customer checking controlled by the driver

We prepared a set for self-service passenger checking primarily for municipal public transportation or for smaller regional public transportation routes where passengers get in the vehicle through the front door and the driver has a responsibility (possibility) to check self-service passenger checking using an on-board computer. Actions performed by passengers while using the  EVK 5.0 BP validator placed in the entrance area by the front door are displayed directly on the terminal of the on-board computer including card validity and coupon type information. Passengers can do the checking themselves using a bank card or some of the known Czech public transportation cards (e.g. the Plzeň Card)  The system is based on the EPIS 4.0X on-board computer and the EVK 5.0BP validator.  The on-board computer contains a backup of the validator transaction database to increase reliability of the checking system. The EVK 5.0 BP electronic validator has undergone homologation for bank cards and the Plzeň card. It is possible to prepare custom solutions for other non-bank cards. The exact description of its behavior will be published within a week.

New type of electronic sign for Plzeň

A new type of the compact integrated electronic sign ELP 173-01Px was developed as a part of the innovation of public transportation stops in Plzeň. It displays current vehicle departures from stops and it also contains full standard equipment of large stop panels.

This sign solution is characterized by 3.8 mm LED spacing first introduced at the international fair InnoTrans 2016 in Berlin. This spacing provides readability from the distance of up to 15 m in direct sunlight. The power consumption of this panel is decreased by half by using „black“ LED.

Features of the sign:

• Display matrix of 30 x 120 LED diodes
• online  departures including the possibility of displaying a graphic surface
• dispatching line combined with the date and time
• command receivers for the vision impaired including acoustic announcements
• UMTS and WiFi communication
• direct sign – vehicle communication
• illuminated stop sign turned on in the dark
• illuminated schedule turned on in the dark
• possibility of integrating TTS (text to voice converter for the vision impaired)

Another innovation in the Czech Republic is using lithium accumulators and power supply from public lighting. This makes installation and operation easier as it is not veccesary to build new access lines as it is possible to use existing public lighting power supply.

New solution of stop LCD for ROPID

A new type of displaying of departure information was utilized as a part of the installation of a stop system into the building of ČD in Kralupy nad Vltavou. The installation was performed for the Prague integrated transportation. The information will be displayed on 55“ and 32“ new LCD panels. An LCD stop panel in the „SLIM” rendering – ELP 855A (a new solution with narrow edges) was used for the 55“size. An industrial Samsung TV equipped with our control was used for the 32“size. It was installed in the upright position.

The new LCD panel solution includes multicolor line displaying, displaying a known stop and displaying current delays. Stops on the route are displayed in a very interesting way, they are listed in lower case under the target stop. Delays are displayed in red color to ensure they are noticed quickly. Graphic design was made for LCD panels in the horizontal position - ELP 855AE  (standard horizontal rendering) as well as for LCD panels in the vertical position  – ELP 832 VE (vertical ordering) as can be seen in the picture. Protective glass can be added to standard monitors if needed.

We put a new system of surveillance information and advertisement systems into operation. This system is supported by a new type of inner LCD for passengers – type VCS 215BE-LW that integrates a vehicle Wi-Fi unit - UCU 4.0 LTE. This new solution communicates simultaneously via up to 4 communication channels:

• communication with an advertisement server (automatic remote advertisement updates and control over displaying them),
• Communication with public  internet – public Wi-Fi for passengers,
• Secured channels for direct communication of the vehicle with the  dispatching
• Channel for displaying transport information from the on-board computer.

International exhibition „InnoTrans 2016″ in Berlin

We took part in the international exhibition of transportation technology „InnoTrans 2016“ in Berlin. Our company was to be found at the A2/111 stand. It was our fourth time at this exhibition. We presented new products from this year’s production in the midst of strong international competition. Our presentation included:

• new type of LCD for passengers VCS 290,
• new type of stop sign ELP 183,
• stop full-color panel ELP 368,
• combined vehicle panel (multi-color modules combined with single-color modules),
• white outer vehicle panels.
• new line of compact on-board computers EPIS 6,
• and other products and system solutions

Stop sign with an integrated LED panel

We prepared for production a new compact type of illuminated stop sign with an integrated LED panel with 3,8 mm LED spacing and readability from 15 m (the head of the sign does not have to be illuminated). the panels is called ELP 183. This sign conception as well as the 3,8 LED spacing was introduced for the first time in the Czech Republic. The LED panel can display 24 text signs, three lines (the number of lines can be modified if requested). The last line can be used as a dispatching line.

The used LED diodes are the same as those used for our new outer vehicle panels of the VLP 19/20/24 line (type D) and they use „black“ LED capable of power consumption lowered by half and higher light while having much higher contrast. This LED technology ensures very good readability even in direct sunlight and is controlled based on the surrounding light.

The panels can communicate with the dispatching center via a GSM/GPRS/UMTS network or via optic or Ethernet if used at a bus terminal. Thanks to their lower power consumption it is possible to use power supply from public lighting. When this power supply is used, embedded accumulators are charged at night and ensure correct function during the day. If requested this panel can be equipped with a command receiver for the vision impaired.

Similar low cost panels can be supplied. These panels were first introduced at the international exhibition InnoTrans 2016 in Berlin from 20.9 to 23.9.2016.

Outer full-color or combined RGB-single-color panels

We developed new types of low input power vehicle outer full color LED panels VLP 19/20RGB or combined LED panels VLP 19K/20K. The panels consist of multi-color, or also single-color LED modules (combined RGB rendering – number and single-color text) controlled by a new panel control unit. In the case of the multi-color LED module it is possible to choose from 256 colors for each LED. 8 degrees of grey can be set on the single-color module. The price of the combined rendering is only 3 – 4 thousand Czech crowns higher than the price of the single color rendering.

The fact that the panels are low input power is evidenced by the fact that the power consumption of the combined side panel in the picture was only 12W including its control unit when the picture was taken. The panels were introduced at the beginning of October 2016.

We supply vehicle camera systems

We are preparing vehicle camera systems with the possibility of connecting up to 10 cameras and recording time of minimum 5 days and more. The basis of the system consists of a vehicle recording LCD (e.g. type VCS156AE2) equipped with a shock resistant hard drive with appropriate storage capacity. The system can be controlled either independently by external buttons or intelligently  via the EPIS 4.x on-board computer. ECU 08P2 is used for this system which makes it possible for the cameras to be power supplied in accordance with the IEE 802.3af regime B standard. The system can also be used for joined trams. We are supplying 72 vehicle camera systems to DPO plc. in cooperation with Master IT plc..

PT Preference using V2X and IBIS-IP in Ludwigsburg

MAN bus belonging to  LVL-Jäger equipped with a V2X – UCU 5.0 LWVG unit with PT preference on Swarco control units.

In Ludwigsburg, Germany (Baden-Württemberg), we successfully tested  public transportation preference using V2X communication. Our OBU unit – version UCU 5.0 LWVG  was installed into a Man bus belonging to the  LVL-Jäger company. The unit was connected to an on-board computer from IVU Traffic and the IBIS-IP standard was used to facilitate communication between these devices. The unit used route and destination information to provide vehicle preference by sending a CAM message containing preference data in the R09.16 format. The test was performed with a reference receiver RSU unit at an intersection controller from Swarco.

Our UCU 5.0 units  have proven again that they meet international standards and that they can be adapted to various operation conditions. Successful tests (description here)  have cleared the way for us to supply 100 pieces of these units to this company.

ON-LINE connection search engine with direct ticket sales in PP

The checking screen and transition to  ON-LINE sale and search.

The passenger transfer regime in regional public transportation makes it possible for passengers to buy tickets with multiple transfers and to choose from multiple routes. Drivers can provide this by searching for a connection ON-LINE, choosing a connection and selling the ticket. The EPIS 5.0A   on-board computer  has been equipped with an  ON-LINE connection search engine . This function is connected with direct ticket sales including printing of a found connection information slip.  This function makes the above described situation easier for both passengers and drivers, and it also ensures that the ticket price is correct. The Herman company has proven its technological lead yet again when this function was integrated into the EPIS 5.0A on-board computer.

New generation of vehicle LCD

Widescreen LCD - VCS 290 simulating 2 screens.

We prepared a new generation of vehicle LCD with a new generation of control PC and a new HW arrangement. The new LCDs use SSD drives with a minimum capacity of 32 GB, their startup time is much shorter, they can store long video sequences, and advertisement or transport campaigns can be loaded in advance and recognized by their validity. They can work with foreign protocols (an example of cooperation with a Transdata on-board computer) or they can work with the latest version of our universal protocol EPISNET.

Mery Christmas and Happy New Year 2021

PF 2021

We wish everybody happy holidays and success in 2021 even in these complicated times. We would like to thank our customers for their interest in our products and services. In 2020, we not only worked on our “usual“ orders but we also worked on some important projects. One of the projects was a new type of   EPIS 5.0A on-board computer with checking  (1000 pieces for IDS JMK) and Backoffice BOS  to manage it. We made progress in integrating V2X communication systems and we integrated PT and ES vehicle preference  including  tram collision prevention. We developed a stop sign with electronic paper  (e-link), solar power supply and a new control server. The last project was a “traffic island camera system” for public transportation vehicles including a supervision server with online recording downloads. In 2021, we plan to introduce innovations in the field of on-board computers and communication units and to further develop SW BOS and Sprinter.

Independent vehicle camera system with remote supervision

¨Set of the “traffic island” independent camera system EPIS 5.0KS consisting of a control unit, LCD terminal, eth. switch and operating unit and up to 16 cameras.

We prepared a new type of vehicle camera system  EPIS 5.0KS . It is not dependent on vehicle electronics (optional). The system is based on  EPIS 5.A,  or more precisely  EPIS 5.0KS  on-board computer. Up to 16 cameras can be connected to the recording system. The “on-board“ camera computer is equipped with 2x SSD (control and record keeping), LTE, GNSS and WIFI modules and a high performance four-core PC. As it has its own SIM card, it is possible to supervise its state and to download recordings online at any time. It is controlled by the latest version of the BOS – KS system.   A special 8 button OV-01 unit is used to operate it from a vehicle. It also includes an   ECU 08LM.7T  ethernet switch with PoE as per IEEE 802.11 at. This innovation adds a  traffic island camera system to our portfolio.

New type of stop sign with e-paper and a solar panel

We developed a new type of stop sign with e-paper  ELP 191. It is powered by solar panels and it does not need the  230V net power supply or overhead line power supply. It is equipped with an  LCD display with e-paper. It can be placed anywhere where the sun shines – you just need to build the needed foundation.

The panel uses brand new control unit technologies, it works with  lithium accumulators  (BMS system), it uses a new type of  low consumption command receiver for the vision impaired (EPNEV 1.24)  and it can control the charging of the accumulators by the solar panels. E-paper illumination is controlled by a contactless capacity button. The consumption of the panel is about 50-70 mW. An LTE modem is used to connect to a server. We also developed a new way of panel control using a new type of control server.
