Balise
Balise
Balise is the safety transmission equipment which transmits safety related information between lineside equipment and train on-board equipment. Its main functions include receiving downstream energy emitted by BTM antenna, emitting up-link telegram and receiving telegram data from LEU.
Balise refers to discrete point of information transmission on railway track. Under different application environments, Balise can be used as both fixed Balise and controlled Balise. When the train passes over Balise and activates it, fixed Balise will transmit prestored fixed message and controlled Balise will transmit variable message which is received from lineside electronic unit (LEU) or fixed message (default message).
