Crossroad Way Command (CWC)

Tram and Light Rail Safety System 

The CWC system uses secure wireless communication to command tram routes. It employs transceivers for real-time communication between onboard and trackside components, ensuring safe navigation.

Ensuring the safe and efficient operation of trams and light trains is crucial as traffic density rises. The Crossroad Way Command System (CWC) addresses this need through secure, real-time communication using ERES81 1353 transceivers for fast, bi-directional data exchange. The system supports applications like automatic speed control, crossroad overpassing, and priority requests, enhancing train safety and network availability. With versatile Digital I/O and RS 422 communication interfaces, the CWC integrates seamlessly into existing infrastructure. Its push-button interface for route commands and resilient, all-weather design make it a vital solution for managing urban mobility and improving tram safety.

Introducing the Crossroad Way Command System (CWC)

The Crossroad Way Command System (CWC), a short-range Two-way radio communication solution of innovation designed to:

• Enhancing Train Safety and Network Availability: Enhance the train operating safety and the availability of the train network. The solution commands the route through simple, standard, and real-time PLC digital Input/Output, utilizing a very fast and secure wireless dialogue between the two transceivers.

• Versatile and Efficient Communication Solution for Multiple Applications: Our universal solution is designed to support various applications. Equipped with automated Digital I/O and serial link RS 422 communication interfaces, it is perfect for short-distance dialogue and can also be utilized for a range of applications. These include train location applications (AVLS), automatic speed control, crossroad overpassing control (ATP), and Crossroad Priority Request (CPR).

Modern Technology for Urban Mobility

The CWC System, crafted with precision, employs a pair of magnetic transceivers, ERES81 1353, with one fitted on board and its counterpart fitted trackside. This unprecedented magnetic sensor pair ensures safety and real-time bi-directional communication between the ground and trackside components.

When the two transceivers are within their facing fields, a 13.56 MHz half-duplex wireless dialogue, secured by a CRC 16, is established. With a wireless radio communication transaction time of just 4 ms, this solution allows for exceptionally fast and secure data exchanges of up to 32 bytes in both directions, even at train speeds of up to 200 km/h.

The ERES81 1353 transceivers can send and receive data and control remote digital outputs from their counterparts.

The route commands of a tram are manually activated by the driver via a push-button interface, offering three command options: “straight,” “right,” and “left.” This information is sent to the onboard ERES81 1353 transceiver through a digital input. When the on-board / ground ERES couple are in the facing field, the digital logic levels applied to the inputs of one ERES are duplicated to the outputs of the other ERES81.
