Problems solved by technology

[0003] However, the track slab of the ballastless track will deform when it is subjected to temperature and train load. With the increase of running time, the deformation of the track slab will evolve into various forms of damage such as warping, cracking, and detachment. These types of damage Once it reaches a certain level, it will seriously affect the stability and performance of the high-speed railway track structure

Abstract

The invention provides a high-speed railway track structure deformation damage monitoring system and method. The system comprises a vibration monitoring module, a temperature monitoring module and a data processing module, the vibration monitoring module is arranged on a roadbed of a railway track and used for monitoring vibration information of the railway track when a train passes and sending the vibration information to the data processing module. The temperature monitoring module is arranged on a concrete supporting layer of a railway track and used for monitoring temperature information of the railway track and sending the temperature information to the data processing module. The data processing module is used for determining a characteristic frequency band according to the vibration information and extracting frequency band energy corresponding to the characteristic frequency band from the vibration information; and judging whether the railway track is damaged or not according to the frequency band energy and the temperature information corresponding to the characteristic frequency band. According to the invention, the deformation and damage of the track plate of the ballastless track of the high-speed railway can be accurately monitored in real time.

Description

technical field [0001] The invention relates to the technical field of railway track monitoring, in particular to a system and method for monitoring deformation and damage of a high-speed railway track structure. Background technique [0002] The ballastless track of high-speed railway is an important track structure to ensure the reliable operation of high-speed railway. [0003] However, the track slab of the ballastless track will deform when subjected to temperature and train loads. With the increase of operating time, the track slab deformation will evolve into various forms of damage such as warping, cracking, and detachment. These types of damage Once it reaches a certain level, it will seriously affect the stability and performance of the high-speed railway track structure. Therefore, the real-time and accurate monitoring of the deformation and damage of the track slab of the ballastless track is of great significance to ensure the safe operation of the train. SUM...
