A high-speed railway track foundation settlement monitoring system and monitoring method

Abstract

The invention relates to a high-speed railway track foundation settlement monitoring system comprising a master monitoring terminal and multiple sub-monitoring terminals which are respectively arranged on all monitoring points of a track. Each sub-monitoring terminal respectively comprises a controller, and a satellite positioning module, an inertia measurement module and a sub-communication module which are respectively connected with the controller. The master monitoring terminal comprises a monitoring server and a master communication module which are interconnected. The master monitoring terminal is communicated with all the sub-monitoring terminals via the master communication module and the sub-communication modules. The invention also relates to a monitoring method based on the high-speed railway track foundation settlement monitoring system. Position information of monitoring points is acquired in real time on the basis of a conventional satellite measurement method in coordination with the inertia measurement module so that accuracy of high-speed railway track foundation settlement monitoring is effectively ensured.

Description

technical field [0001] The invention relates to a high-speed railway track foundation settlement monitoring system and a monitoring method. Background technique [0002] The two most important characteristics of high-speed railways are high ride comfort and high stability. These two characteristics determine the significance and importance of track foundation settlement and deformation monitoring. [0003] When the driving speed is below 160km / h, the irregularity of the long-wave height in the wavelengths of 56, 70, 83, and 97m can not be managed, but at the speed of 200, 250, 300, and 350km / h respectively, the excitation frequency It is equivalent to the vertical natural vibration frequency of 1Hz of the high-speed vehicles in Japan and France, causing the car body to produce "unexplained strong vibration", but the rail inspection car cannot detect this vibration, and the road maintenance machinery cannot be repaired. With this problem It has gradually been realized by peo...

Problems solved by technology

[0006] In view of the above problems, the satellite measurement method is widely used at present, but the measurement system uses radio waves to work, and is often affected by the ionospheric weather. When the ionospheric weather is disturbed, the measurement system will produce an error of several kilometers. Therefore, Changes in the ionosphere seriously affect the accuracy of single-frequency satellite receivers, and ionospheric scintillation will affect the work of all types of satellite receivers, especially in certain fixed areas, often unable to perform high-precision measurements, satellite measurement system failure events Occurs often
