BSV TR-20PE

The system of non-contact switch setting (hereinafter BSV) by inductive method is designed for transmission of short data messages between the public transport vehicle and the fixed part of the switch or the identification or control point of the crossing. The communication is realized by means of a magnetic field generated by a transmitting coil located on the underneath of the public transport vehicle towards the track and sensed by a coil located between the tracks or located on the collector and sensed by a coil located above the track. Both generations of the BSV system operate in free bandwidth according to General Licence No GL-30/R/2000 issued by the CTU on 21.11.2000 under No 502500/2000-613 with a transmission rate of 1200 bit/s (AM) or 4800 bit/s (FM). The length of the transmitted payload is usually 36 bits. Security is by CRC-12 or CRC-16.

The unit is designed for all types of builds, i.e. automatic, using the on-board computer or manually using the buttons on the driver's terminal... Other information sent within is obtained from the on-board informatics.
