Problems solved by technology

[0004] The problem with the above scheme is that it is too complicated and involves many system devices, and it is necessary to provide repeated information to realize the judgment of missing reading through comparison. In practical applications, due to the high reliability of the transponder equipment, the situation of missing reading is extremely high. Infrequently, in fact a complex scheme is used to deal with the effects of a very rare failure

Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] see figure 1 and figure 2 , a fault-oriented safety transponder detection system, including: a binocular camera 1 and a light source 2 installed side by side with the antenna of the BTM at the bottom of the train, and a safety main processor 3 connected to the binocular camera 1 . The installation direction of the binocular camera 1 is perpendicular to the longitudinal direction of the vehicle.

[0034] The image sensors of the two cameras of the binocular camera 1 respectively adopt color and grayscale sensors, which can perceive visual images in different bands. The perceived object is mainly the transponder installed on the track (generally a European transponder), and the appearance characteristics of the transponder mainly include shape, size ratio and color.

[0035] The two cameras of the binocular camera 1 are respectively installed on both sides of the a...

Abstract

The invention discloses a fault-oriented safety transponder detection system. The system comprises a binocular camera and a light source which are arranged at the bottom of a train side by side with an antenna of a BTM, and a safety main processor connected with the binocular camera. Two cameras of the binocular camera are respectively arranged on two sides of the antenna of the BTM; the binocular camera collects real-time images from a transponder to steel rail sleepers on the two sides, the safety main processor carries out image feature extraction on the real-time images, the extracted image features match pre-configured pre-stored images, and the track and the transponder are recognized according to the matching result. The invention further discloses a transponder detection method. The transponder information reading scheme of the signal system can be greatly simplified, and the system safety is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to transponder detection. Background technique [0002] According to ETCS standards Subset-036, Subset-088 and Subset-091, the tolerable hazard rate THR (dangerous side failure per hour) assigned by European balises and balise transmission modules BTM, where a single balise The missed reading THR caused by the transponder itself is 2x10-5, and it reaches 10-9 under the condition that there are two transponders to organize the transponder group, and it should reach 10-7 by the on-board transponder equipment BTM (including antenna). However, the BTM (transponder reading module) itself has no technical means for directly judging missing readings, so it is not possible to rely solely on these devices to achieve fail-safety. [0003] In order to solve the problem of missed reading and prevent security risks, it is necessary to take mitigation measures at the level of the signal sys...
