Vehicle-mounted ATC equipment operation and maintenance system based on non-contact data acquisition

Abstract

The invention discloses a vehicle-mounted ATC equipment operation and maintenance system based on non-contact data acquisition. The system comprises a signal acquisition unit, a vehicle-mounted end information processing unit, a vehicle-ground wireless communication unit and trackside equipment, wherein the signal acquisition unit is used for acquiring relevant vehicle-mounted information of vehicle-mounted ATC equipment through a non-contact sensor and transmitting the relevant vehicle-mounted information to the vehicle-mounted end information processing unit after amplification and analog-to-digital conversion; the vehicle-mounted end information processing unit is used for collecting driving logs of all subsystems of the vehicle-mounted ATC, carrying out integrated storage on the vehicle-mounted information sent by the signal acquisition unit, and transmitting the integrated data to the vehicle-mounted wireless communication unit; the vehicle-ground wireless communication unit is used for transmitting the data integrated by the vehicle-mounted end information processing unit to the trackside equipment; and the trackside equipment is used for processing the integrated data through a classification algorithm and a prediction algorithm to realize fault diagnosis and early warning of possible faults. According to the system, the vehicle-mounted information can be acquired on thebasis of maintaining the reliability of the equipment, and meanwhile, the fault diagnosis and early warning can be realized by analyzing the data through the trackside equipment, and the operation and maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the field of railway science and technology, in particular to a vehicle-mounted ATC equipment operation and maintenance system based on non-contact data collection. Background technique [0002] In the train operation control system, the on-board ATC (Automatic Train Control) equipment logbook records all the information of the entire operating cycle of each subsystem. Analyzing the logbook is also an important means to monitor on-board equipment and trace system failures. However, the existing vehicle-mounted ATC equipment does not have effective monitoring and recording of the train interface, system input and output, and train speed sensors; and the lack of such information in the current operation and maintenance methods will lead to the inability to quickly and accurately locate some faults, and the fault responsibility cannot be accurately divided. Reduced the efficiency of operation and maintenance. In order to more acc...
