Application of Inertial Reference Method in Metro Track Detection
The service life of subways is related to the loss of subway tracks.it can effectively improve the service life of subways to detect and repair track problems in time.In order to improve the service life of urban subways,a subway track wave wear and tear detection system based on the inertial reference method is studied and constructed.The system takes the inertial reference method as the core,cooperates with accelerometers,detects vehicles,and detects the wear and tear of subway tracks.The results show that the detection standard deviation of the inertial reference method is always lower than that of the string measurement method.The detec-tion standard deviation of the string measurement method is 0.79 mm with the detection length of 400 mm,but the detection standard deviation of the inertial standard method is 0.72 mm.The detection results of the detection system based on the inertial reference method are basically consistent with the actual results.It is lower that the detection cost of the subway track wear and tear detection system constructed through the research,and the detection accuracy meets practical application requirements.
