Clearance in regional transport - VLD

uvod-odbaveni-region-220424The check-in of passengers in regional regular transport differs from urban check-in mainly in the fact that passengers board through the front door and are checked in by the driver, with the passenger being charged a much larger number of fares. This is also the reason for the requirement for a larger screen on the driver's LCD terminal (today at least 10"), which must allow easy selection of these fares, i.e. it must contain not only the journey data, but also the fare zones, fare types, their combinations, a numeric keypad and other elements. 

The on-board computer with check-in can be a split version, where the EPIS 5.0xA on-board computer is connected to the EPP 5.0 customer check-in unit, which contains elements for passenger check-in - customer display, bank and non-bank card reader, thermal printer and QR code reader. This split concept allows for easier installation in the vehicle and is essentially equivalent to a "lie-flat validator" solution. It may or may not include a money box. Historically, a compact version of the EPIS 5FCS has also been produced.

A change in the regional clearance set-up is the UCU 5.0 vehicle communication unit, which can independently mediate vehicle communication (acting as a vehicle router) and the clearance systems then connect via it to the relevant 'back office' for transaction processing. Thus, the on-board check-in computers do not need a GSM/LTE/5G modem.

On-board computers with check-in - split version EPIS 5.0A or EPIS 5.0B with extra large display for easy driver operation EPT 10.1" when issuing tickets (can be operated with gloves). The computer also includes an EPP passenger check-in unit, contactless smart card reader including bank cards, GPS with 2.5 m accuracy, GSM / GPRS / LTE communication, WiFi, quad independent digital annunciator, 4x position for SAM modules, up to 32 GB SSD, 4" colour LCD for customers, 2x25W and 2x10W amplifiers, Ethernet, USB, multi-core processor on request and other technical conveniences.

Software for data preparation and "Backoficce" payment processing is available for the on-board computer with check-in.

The EPIS 5.0X unit meets:
  • Temperature requirements for vehicle operation (-20°C to +70°C) - for higher negative temperatures this means that the vehicle will have to be held in RESET for a period of time to allow the interior of the unit to warm up with "waste" heat (if this occurs at all, it is a matter of a few tens of seconds). For an additional charge from -40°C to +80°C.
  • Performance requirements - determined by the processor used, based on PC or ARM architecture as appropriate. If required, up to 4 core processors with large memory content can be supplied.
  • Low power consumption - continuous power consumption without printing around 20W of which 12W will be used by the driver LCD.
  • Large memory capacities - 32GB SSD as standard and DDR3 RAM from 2GB.
  • versatile use for driver-pay systems - easily configurable large control LCD touch screen terminal with capacitive touch screen - also possible EPT 12".

Recommended wiring in VLD vehicle

SOR-ODBAVENI-1-usporadani-mThe EPIS 5.0X on-board computer with check-in is designed for public passenger transport, especially in regular services (also possible in public transport). It combines passenger check-in including on-line communication with backoffic or DZC (data clearing centre), dispatching and communication capability, information systems management, public or on-board WiFi and other options. A principle diagram of the general on-board circuitry, particularly VLD, is shown in the following figure. The general wiring diagram for the JMK ITS is here. It shows that it allows to integrate many systems together due to its power.


  1. On-board computer with EPIS 5.0Ax check-in (according to the mechanical design) in the equipment of the control unit EPC 5.0A1, the check-in unit EPP 5.0A LQB, the touch LCD driver terminal EPT 5.10A and the external switch EPI 5.The external EPI switch switches the standard +24V voltage to the HS power output (main switch) and, on request, to the PS power output (auxiliary switch).
  2. Common GNSS (Global Navigation Satellite Systems) and GSM/LTE antenna. This combined antenna is placed on the roof of the vehicle (bus) for better satellite reception for vehicle positioning and also for better communication via GSM/LTE. For this purpose, the combined antennas are supplied with a high quality cable for GSM/LTE reception (very low attenuation).
  3. As the EPIS 5.0X on-board computer is permanently energised directly from the vehicle batteries (even though it is in a "stand by" state), this OIS (check-in and information system) wiring must be fused with a separate fuse. The maximum consumption is determined by the consumption of the EPIS 5.0A on-board computer and other components connected to the HS power output (boards, markers, LCD, command receiver, ...).
  4. The docking connector to the on-board computer base allows easy replacement of the unit. A standard connection cable is routed from it, e.g. for EPIS 5.0A - KEP 5A-01/xx, where xx is the cable length in decimetres. If the vehicle contains an acoustic system for playing a radio or other sound source, additional outputs and a switching relay must be used - cable KEP 5A-02/xx (diagram to be added).
  5. The external vehicle loudspeaker is located above or below the first door of the vehicle - it is activated either by a command receiver for the destination stop announcement or by the on-board computer if there is "any" exception on the route as a warning to passengers (e.g. a route closure,....).
  6. Internal acoustic wiring for standard announcements to passengers from a digital annunciator, driver or dispatcher.
  7. IBIS bus hub - a junction box in the vehicle to be used as a distributor for the IBIS bus and HS power supply. Depending on the number of components connected to this bus, 1-3 hubs should be used in the vehicle.
  8. Vehicle faceplate usually showing the destination station and line number with dimensions according to the operator - e.g. VLP 19x144 GI.
  9. Vehicle side board displaying the line number, destination station and intermediate stops or other additional information - e.g. VLP 19x112 GI.
  10. Rear vehicle board (number) showing the line number - e.g. VLP 19x32 GI.
  11. Internal LED board for passenger information - e.g. VLP 10x120 RI.
  12. Time and zone board - this can also be an internal LED board or LCD for passenger information, e.g. VLP 12x64
  13. Command receiver for signaling from the blind - EPNEV 3.x4
  14. Ticket marker usually located at the first door and now standard on the IBIS bus - e.g. ETM 4.0
  15. Single-bit inputs to the on-board computer providing basic system functions:
    • START - switches the on-board computer from a "stand by" state to an active state by applying +24V from the vehicle key. The system is deactivated by turning off the key and then after the driver logs off.
    • Emergency button - sends an "alarm" message to the dispatcher regarding a vehicle emergency and in particular the driver (the button can be hidden in the driver's cab).
    • First door and next door - feeds the door status to the PP for subsequent evaluation of vehicle behavior statistics. In case the inputs are not connected to the door lights but to the signals from the "MUX" units, it is usually necessary to connect auxiliary resistors between the input and the vehicle ground to reduce the voltage. The resistors used are from 560 Ohm and above depending on the vehicle wiring.
  16. Ethernet communication unit EPU 08P.1F5P
  17. Internal LCD for passengers - e.g. VCS 185 or other types,
  18. Frontal accident camera
  19. Course indicator VLP 8x35
  20. Passenger counting units UCP 02
  21. Communication unit with GPS and V2X for public transport preference - UCU 5.0VG 

Allows for buses that are operated as a regular bus and also as a tour bus to connect the existing vehicle acoustic system from the amplifier or radio, video, etc. via relays. The on-board computer then activates the output of the unit and switches an external auxiliary relay in the event of a stop announcement to the vehicle. This disconnects the internal bus amplifiers and connects the amplifiers from the on-board computer and makes the announcement. When it is completed, the relay then drops and the speaker line to the vehicle is again through to the bus amplifier.  Thediagram shows  anEPNEV 3.x4I blind signaling receiver approved for use in the JMK ITS (generally it can be used elsewhere where only receiving and transmitting signals over the IBIS bus is done).

Example of ECU 08L.1Fa3L switch wiring in an IDS JMK vehicle using a front safety camera and heading indicators. As a special feature, the connection of the EPNEV 3.18 or EPNEV 3.28 (selective version) command receiver is demonstrated. The other 4 already quite standard Ethernet ports are intended for connection of the EPIS 5.0A control unit, passenger LCD panel, e.g. wide-screen VCS 290 or standard VCS 185. And there are still two more ports available for future expansion - e.g. ETM 4.0.
