VECOM®

WAY SIDE VEHICLECOMMUNICATION SYSTEM

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 identificationA 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 changingA 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 registrationThe 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.

VECOM®-CT FeaturesVECOM®-Compact is the latest generation of VECOM® roadside

systems with the following properties:

� Limited footprint thanks to 3 compact 3 HE modules;

� A RS485 serial channel for connecting to an intelligent

roadside system or via the VETAG serial protocol;

� An extra RS485 serial channel for controlling additional

digital communication or an extra connection to a central

system;

� A RS232 serial channel for diagnostics, configuration and

downloading software;

� New VECOM®CT Loop Transceiver with excellent noise

cancelling features;

� Extensive parallel input and output possibilities;

� From and to passing vehicles;

� From and to linked central systems;

� Extensive, configurable 19 bit VETAG code conversion;

� 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;

� 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:

� Improved diagnostics (including detection of a dead loop);

� Improved insensitivity to EM noise, which allows the unit to

better handle environments with a high level of EM noise

(including Light Rail);

� Possibility of bridging longer distances (up to 1000 m

between the loop and VECOM®-CT unit).

BenefitsVECOM®-CT offers a number of specific benefits, making

VECOM®-CT an ideal and cost-effective choice:

� Highly reliable data communication;

� Simple system with many extension options without capital

destruction;

� Easy to install communication loops (without regulation);

� State-of-the art technology;

� Improved diagnostics and less sensitivity to noise;

� Larger distance between loop and VECOM®-CT unit

possible.

Technical specifications

Software functions � 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 � When detecting a vehicle, an entry and/or exit vehicle

alert is reported.

Power supply � AC: 176 VAC < U < 253 VAC / 50Hz / 1A.

� 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 � 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.

� Synchronisation: Via the synchronisation interface, the

VECOM®-CT can be synchronised with the interface of

other VECOM® systems.

� 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.

� Diagnostics: By means of LED’s and via the service channel

(RS232).
