Large-capacity btm automatic detection device

Abstract

The invention discloses an automatic detection device of a high-capacity BTM. The automatic detection device of the high-capacity BTM comprises a FSK and PSK detection module, a 27M receiving module, a control module, and a self-inspection sending module. The FSK and PSK detection module is used for receiving and detecting a FSK Balise telegram signal and / or a PSK Balise telegram signal of a Balise transmission module (BTM). The 27M receiving module is used for detecting a 27M power signal strength of an A4 interface of the BTM, and is used for supplying power to a power supply module. The control module is used for acquiring a detection result of the BTM based on the detection result of the FSK and PSK detection module as well as the detection result of the 27M receiving module, and is used for controlling the self-inspection sending module to send a FSK self-inspection telegram signal and / or a PSK self-inspection telegram signal to the BTM while the FSK Balise telegram signal and / or the PSK Balise telegram signal are (is) not received by the FSK and PSK detection module. The self-inspection sending module is used for sending the FSK self-inspection telegram signal and / or the PSK self-inspection telegram signal to the BTM based on instructions of the control module. The disclosed automatic detection device of the high-capacity BTM is able to detect working conditions of the high-capacity BTM, thereby guaranteeing the driving safety effectively.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a BTM automatic detection device. Background technique [0002] At present, the train control system used in China's general-speed lines is the CTCS-0 train control system, and the train control on-board equipment is equipped with LKJ (train operation monitoring device). However, there are many problems in the modification, maintenance and management of the on-board data of the LKJ equipment. In order to solve the existing problems of the existing LKJ, it is necessary to use the transponder system to provide the vehicle control data to the LKJ, so that it finally has the function of the CTCS-1 train control system. [0003] However, in the existing European standard transponder system, the user data volume of a single transponder device is only 830 bits, which is far from meeting the needs of system transformation. It is necessary to consider increasing the amount of informa...

Problems solved by technology

[0003] However, in the existing European standard transponder system, the user data volume of a single transponder device is only 830 bits, which is far from meeting the needs of system transformation. It is necessary to consider increasing the amount of information transmitted by the system and also serve as the existing CTCS-2 level The train control system, by adding a new PSK channel on the basis of the European standard balise, realizes the expansion of the amount of information transmitted by the balise system, and forms a large-capacity balise transmission system, including a large-capacity BTM (balise transmission module) and a large-capacity balise

[0004] However, there is currently no relevant solution for large-capacity BTM detection, so there are certain security risks
