A transponder (Balise) is a point-type device for transmitting information from the ground to a train, and is divided into a fixed (passive) transponder and a variable (active) transponder. The main purpose is to provide reliable ground fixed information and variable information for train control vehicle-mounted equipment. That is, the transponder can send message information to the vehicle-mounted subsystem, and can transmit fixed information or connect with the trackside unit to transmit variable information, which is an indispensable part in the safety system of the whole signal system.
The transponder device is used for transmitting fixed and real-time variable information such as basic line parameters, line speed, special positioning, basic road parameters, line speed, special positioning, train operation target data, temporary speed limit, station route and the like to the train control system, and the fixed and real-time variable information is used for realizing the mutual communication between the ground and the train at a specific place.
Between two rails of a railway line, a large number of small yellow boxes, i.e. transponders, which may be called "ground transponders", are installed, which may be simply understood as a storage device installed on the ground like a hard disk, with the only difference that a "ground transponder" may transmit internal storage information to the train in a wireless manner.
A vehicle-mounted transponder antenna (induction antenna) is installed to train both ends cab below, and when the train head moved the top of ground transponder, vehicle-mounted transponder antenna just can send electromagnetic energy to ground transponder, and ground transponder just can be with this energy conversion working power supply, makes the inside electronic unit of transponder begin to work, gives the train with information such as the inside line speed that stores of transponder.
The working principle of the transponder comprises: when the interrogator on the train passes through the ground transponder, the transponder is activated by the transient power of the interrogator to enter a working state, and the running data stored in the transponder is continuously sent to the interrogator.

In addition, because the induction antenna 15 is a fixed end, an electromagnetic interference and protection device can be conveniently configured around the induction antenna 15, so that the electromagnetic environment of the vehicle can be simulated.
