A vibration signal-based train positioning device and method

Abstract

The invention discloses a train positioning device based on a vibration signal, which comprises a plurality of first vibration sensors arranged at the station track, a communication module, a PC data processor and a plurality of second vibration sensors arranged on the train; The PC data processor is used to receive the vibration signals sent by the communication module and divide the signals collected by multiple first vibration sensors into track vibration signal groups, and divide the signals collected by multiple second vibration sensors into train vibration signal groups. In the present invention, the vibration sensor detects the vibration of the train and the track in real time, and feeds back the detection result to the PC data processor through the communication device in time, and the PC data processor analyzes and calculates the feedback vibration signal, and determines whether the train enters the station according to the calculation result , compared with the train positioning method based on speed measurement in the prior art, the positioning device in this solution has high positioning accuracy and no cumulative error.

Description

technical field [0001] The invention relates to the technical field of urban rail train positioning technology, in particular to a vibration signal-based train positioning device and method. Background technique [0002] Our country has entered the era of high-speed rail. Whether we can accurately locate the train will affect our control of the train interval, so as to ensure the safety of the train, the efficiency of the train dispatch and the real-time control of the train's driving information. [0003] In the prior art, there are many train positioning methods, such as using a speed measurement-based train positioning method or a query / transponder to locate a moving train; the speed-based train positioning method is relatively simple in principle, according to the current speed of the train and the distance from the platform to predict the arrival time of the train, but the error is relatively large. The accuracy of the real-time speed will affect the positioning accurac...
