Abstract

The invention provides a state monitoring device and method for an optical fiber sensing turnout point switch. The device comprises a fiber bragg grating sensor, a transmission optical fiber, a signaldetection device, a data processing terminal and an alarming device; and the method is used for detecting multiple parameters of a working state of the turnout point switch in real time and giving analarm for an abnormal condition of the turnout point switch on the basis of the device. The device provided by the invention is good in stability and high in disturbance resistance; and meanwhile, the method provided by the invention is capable of comprehensively and systematically realizing the state monitoring of the turnout point switch and provides a sufficient scientific basis for the safetyoperation of the rail traffic.

Description

technical field [0001] The invention relates to the field of rail traffic safety monitoring, in particular to a device and method for monitoring the state of a switch machine with an optical fiber sensor. Background technique [0002] In the rail transit system, the switch machine is used as the conversion equipment for track change and line intersection and separation, which will be affected by many factors such as long-term heavy load and harsh working environment, which will cause damage or deformation of the switch machine , making the turnout point machine unable to work normally, and even endangering the safety of train running. In order to avoid safety accidents, rail transit safety monitoring engineers or staff should monitor and maintain the working status of the switch machine and the health of its structure in a timely manner. [0003] At present, manual detection is mainly used to monitor the working status of switch machines, which is inefficient and difficult ...
