Problems solved by technology

[0002] With the continuous increase of train running speed, only relying on the way of sending blockage information to on-board equipment by track circuit can no longer meet the requirements of safe high-speed running of trains in terms of information volume. It is necessary to increase transponder equipment to provide a large amount of fixed information and variable information

Embodiment Construction

[0017] combine figure 1 Generally, the working condition of the existing transponder is that the vehicle-mounted antenna installed at the bottom of the locomotive continuously transmits power to the ground at 27.095MHz±5KHz; and receives coded information from the transponder when the locomotive passes the ground transponder.

[0018] When the train passes above the transponder, the transponder receives the electromagnetic energy 27.095MHz±5KHz emitted by the on-board antenna, converts it into electrical energy, makes the electronic circuit in the transponder work, and sends the 1023-bit datagram stored in the transponder The code length of 4.234MHz±200KHz message cyclic transmission is 1023 bits; the available code length is 830 bits until the power disappears (that is, the vehicle antenna has left).

[0019] combine figure 2 , the situation of the dual-frequency transponder is similar to that of the existing transponder, the difference is that the existing transponder only...

Abstract

The invention provides a dual-frequency responder system which comprises a ground dual-frequency responder, a vehicle-mounted dual-frequency responder reader, a vehicle-mounted antenna and affiliated equipment thereof, and a vehicle-mounted power supply. By using the dual-frequency responder system, the problem of backup redundancy of the responder can be solved.

Description

technical field [0001] The invention belongs to the field of rail transit information engineering and control, in particular to a dual-frequency transponder technology. Background technique [0002] With the continuous increase of train running speed, only relying on the way of sending blockage information to on-board equipment by track circuit can no longer meet the requirements of safe high-speed running of trains in terms of information volume. It is necessary to increase transponder equipment to provide a large amount of fixed information and variable information. [0003] In the general rules of the CTCS technical specification of the China train operation control system, transponder equipment must be used from CTCS-1 to CTCS-4. Therefore, the transponder is an indispensable equipment in the speed increase of existing railway lines and passenger dedicated lines. [0004] The transponder uses the principle of electromagnetic induction and is used to realize high-speed ...
