Abstract

The invention relates to a failure-safe infrared bidirectional responder system comprising a vehicle-mounted reader and a ground responder, wherein the vehicle-mounted reader is installed on a mobile vehicle, and the ground responder is installed beside a track; and the vehicle-mounted reader and the ground responder comprise respective transmitting units (1), receiving units (2) and corresponding infrared receiving and transmitting arrays (3). The invention has the advantages that the failure-safe infrared bidirectional responder system can reliably realize the bidirectional infrared data communication between the vehicle and the ground, and since the reader and the responder can output signals to respective control systems, the failure-safe infrared bidirectional responder system meets the requirement of accurate positioning of the vehicle; and the failure-safe infrared bidirectional responder system realizes the guiding safety of equipment failures, improves the running safety of track traffics, has no interference on a radio-frequency responder system in the neighboring position and improves the adaptability of equipment.

Description

technical field [0001] The invention relates to the field of fail-safe technology and the field of query transponders, in particular to a transponder system under the specific requirements in the field of rail transit operation control. Background technique [0002] In the field of rail transit operation control, query transponder systems are required for accurate positioning of vehicles. In specific fields, transponder systems are required to have two-way data communication capabilities. Both vehicle-mounted readers and ground transponders can output signals to their respective control systems. Therefore, the vehicle-mounted reader and the ground transponder should be made into a symmetrical structure; it has a fault-oriented safety function, so the system should be designed using fail-safe theory and fault-tolerant technology; it has high communication reliability and wide-angle communication coverage, so the system should be Uses various redundant technologies; has a low ...
