Comprehensive detection system of high-speed railway balise

Abstract

The invention discloses a comprehensive detection system of a high-speed railway balise, and the system belongs to the field of railway equipment detection. The system comprises a balise transmission module (BTM) main machine, a BTM antenna and an automatic train protection (ATP) system which communicate and are connected with the BTM main machine, a high-speed data acquisition device which communicates and is connected with the BTM main machine, and a detection, analysis and processing device which communicates and is connected with the high-speed data acquisition device through the BTM main machine. According to the system, when a train runs at high speed, the high-speed data acquisition device acquires the signals of the balise at high speed, the detection, analysis and processing device displays the waveform, frequency spectrum, detailed message information, characteristic indicators and the like of the signals of the balise after analyzing and processing the signals of the balise which are acquired and processed by the high-speed data acquisition device, the detection system is applicable to high-speed railway environments with the hourly speed being no less than 350km, accurately detects the balise system of the high-speed train, and ensures that the balise system works reliably.

Description

technical field [0001] The invention relates to the field of railway equipment detection, in particular to a comprehensive detection system for high-speed railway transponders. Background technique [0002] Since 2005, China has begun to introduce European standard transponder system equipment, which has been widely used in domestic railways. The European standard transponder system equipment consists of ground equipment and vehicle equipment. The ground equipment includes transponder and LEU (ground electronic unit), and the vehicle equipment includes transponder transmission module (BTM) and antenna. [0003] The transponder system is a high-speed point-type data transmission device based on the principle of electromagnetic induction. It is used to realize the mutual communication between the ground and the train at a specific location. The transponder provides reliable ground fixed information and variable information to the train control vehicle equipment. . [0004] T...
