VECOM®- CompactVehicle identification and priority

VECOM®

Smooth traffic flow for trams and buses is an essential

requirement for everyone. For passengers, who prefer

minimal waiting times and other delays. For transport

companies looking to offer optimal service and

efficient operations. VECOM® technology can be a key tool in

achieving this.

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 points changing, reporting in and out at stops and

vehicle localisation and registration.

Priority request

Based on vehicle identification, a pre-configurable

priority request is submitted to a traffic control

installation. 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 if that is necessary.

Automatic point changing

A pre-configurable priority request is sent to a traffic

control device using vehicle identification. 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.

Vehicle registration

The roadside equipment can register the identification

details of passing vehicles and the time of passing. This

function is a highly effective tool for analysing and

improving service levels. Furthermore, this function is

essential to running travel information systems effectively,

including Compact Bus Stations.

Versions

The VECOM® Compact systems are available in VECOM®-C or

VECOM®-CT versions and have 2, 4 or 8 loop capability.

VECOM®-C

System with full VECOM® functionality and suitable for the

loop buffer. The loop cable with the 25-pole sub-D plug of

the predecessor can be connected directly to the VECOM®-C

unit. Parts of the existing BWS systems are used for this

configuration, i.e.:

Loop cable;

Loop Distribution Panel / Wide Style (LDP/WS);

Loop buffer MK2.

VECOM®-CT

In the VECOM® Compact Transceiver version of VECOM®-C,

the full new functionality of the new VECOM® as described

will be available. Currently, the existing parts as described

under VECOM®-C are obsolete and the following extra parts

are required:

VECOM®-C Loop cable;

VECOM®-C LDP (Loop Distribution Panel);

VECOM®-C Transceiver.

VECOM®-C Features

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

systems with the following properties:

Limited footprint thanks to 3 compact 3 HE modules;

An RS485 serial channel for connecting to an

intelligent roadside system or to a central system via the

CVU protocol or via the VETAG serial protocol;

An extra RS485 serial channel for controlling the digital

entrances and exits or an extra connection to a central

system;

An RS232 serial channel for diagnostics, configuration

and downloading software;

Extensive parallel input and output possibilities;

From and to passing vehicles;

From and to linked central systems;

Extensive, configurable 19 bit VETAG code conversion.

Benefits

VECOM®-C offers a number of specific benefits, making

VECOM®-C 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®-C unit

possible;

The option to combine two loops offers the following

benefits:

The driving direction can be detected with the

combined loops;

The two overlapping 8-shaped loops can

prevent double detections.

The entire VECOM® function, including the type

radio link modulation, is configurable. 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);

Longer “feeder” cables possible (up to 800 m

between the loop and VECOM®-CT unit).

Specifications

Software functions

Software functions approx. 200 different vehicle codes can be decoded.

Serial channels when detecting a vehicle, an exit and/or 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®-C system can also be connected to an external 24 VDC inlet).

channel 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®-C can be synchronised with the

interface of other VECOM® systems.
