  1. 1. VECOM® WAY SIDE VEHICLE COMMUNICATION SYSTEM
  2. 2. VECOM® is an inductive communication system at the basis of many vehicle stop and central unit functions. VECOM® is an abbreviation of ‘Vehicle Communications’, referring to transparent information exchange between mobile vehicle equipment and stationary equipment along the route . VECOM® is used to exchange data between vehicle equipment and roadside equipment. Vehicle identification is used for priority requests at intersections, automatic or manual point control changing, route tracking, punctuality and regularity calculations, reporting in and out at passenger stops and vehicle localization and registration. Priority requests based on vehicle identification A pre-configurable priority request is submitted to a traffic light controller system. With VECOM® , it is possible to add the vehicle status in comparison to the timetable to this request. This enables using conditional priority, meaning that the vehicle is given priority only when necessary. Automatic point changing A pre-configurable priority request is sent to a switch point control device using vehicle identification. The vehicle data (ID, line number, run number and more) is sent from the vehicle to the VECOM® - CT system which determines the required point position. This ensures that the switch points are set to the required position automatically and well in advance, allowing for the vehicle to continue without any delays. Driver entered requests can also be send to the point machines if required. Vehicle registration The roadside equipment can register the identification details and time of passing vehicles. This function is a highly effective tool for analysing and improving service levels. Furthermore, this function is essential to run travel information systems effectively, including Compact Bus Stations. Smooth and predictable traffic flow for trams and buses is an essential requirement. It is crucial to provide passengers with minimal waiting times and smooth operations. For transport companies looking for optimal services and efficient operations, VECOM® technology can be a key tool.
  3. 3. VECOM® -CT Features VECOM® -Compact is the latest generation of VECOM® roadside systems with the following properties: ƒƒ Limited footprint thanks to 3 compact 3 HE modules; ƒƒ A RS485 serial channel for connecting to an intelligent roadside system or via the VETAG serial protocol; ƒƒ An extra RS485 serial channel for controlling additional digital communication or an extra connection to a central system; ƒƒ A RS232 serial channel for diagnostics, configuration and downloading software; ƒƒ New VECOM®CT Loop Transceiver with excellent noise cancelling features; ƒƒ Extensive parallel input and output possibilities; ƒƒ From and to passing vehicles; ƒƒ From and to linked central systems; ƒƒ Extensive, configurable 19 bit VETAG code conversion; ƒƒ The entire VECOM® function is configurable, including the type radio link modulation. This gives greater flexibility and enables completely adjusting the function without any changes to the hardware; ƒƒ All software, including modulation and filtering algorithms, can be downloaded via the serial port. Further benefits in combination with the “Loop Transceiver” (VECOM®-CT) are: ƒƒ Improved diagnostics (including detection of a dead loop); ƒƒ Improved insensitivity to EM noise, which allows the unit to better handle environments with a high level of EM noise (including Light Rail); ƒƒ Possibility of bridging longer distances (up to 1000 m between the loop and VECOM® -CT unit). Benefits VECOM® -CT offers a number of specific benefits, making VECOM® -CT an ideal and cost-effective choice: ƒƒ Highly reliable data communication; ƒƒ Simple system with many extension options without capital destruction; ƒƒ Easy to install communication loops (without regulation); ƒƒ State-of-the art technology; ƒƒ Improved diagnostics and less sensitivity to noise; ƒƒ Larger distance between loop and VECOM®-CT unit possible.

Technical specifications Software functions ƒƒ VECOM identification information from the vehicles can be send to TSC or central systems and can be decoded by the VECOM-CT system for up to 200 relay output control table entries. Serial channels ƒƒ When detecting a vehicle, an entry and/or exit vehicle alert is reported. Power supply ƒƒ AC: 176 VAC < U < 253 VAC / 50Hz / 1A. ƒƒ DC: 22,8 VDC < U < 25,2 VDC / 1,3A (For integration into other equipment, the VECOM® -CT system can also be connected to an external 24 VDC inlet). Interfaces ƒƒ 3 Communication Channel; 3 Communication 1 x RS232 (service channel) and 2 x RS485 compatible. 1200, 9600 or 19200 bps half duplex, VCU protocol (in accordance with ISO1745) or VETAG serial output. The second RS485 channel can be used for controlling parallel inputs and outputs or to connect an additional central system. Please note: A distance up to 1 km is possible by adding a SERIO module. ƒƒ Synchronisation: Via the synchronisation interface, the VECOM® -CT can be synchronised with the interface of other VECOM® systems. ƒƒ Parallel inputs and outputs: A maximum of 4 x I/O 1609 modules can be connected on the VECOM® -CT units. This allows for making a large number of inputs and outputs available. The Relais contacts are at 1 kVDC isolation voltage. Contact current 0.5 mA < I < 100 mA, Contact tension 3.0 V < U < 50 V. ƒƒ Diagnostics: By means of LED’s and via the service channel (RS232). Mechanical ƒƒ Euro rack: 42TE/3HE or 84TE/3HE ƒƒ Loop buffer: 235 x 131 x 56 mm (lxbxh), IP67 ƒƒ Loop transceiver: 235 x 131 x 56 (lxbxh), IP67 EMC ƒƒ EN 61000-6-3 Emission ƒƒ EN 61000-6-2 Immunity
