The invention discloses a fiber bragg grating turnout switching locking force monitoring system, and relates to the technical field of switch machine monitoring, the fiber bragg grating turnout switching locking force monitoring system comprises a fiber bragg grating track stress sensor and a judgment module, an industrial personal computer is further connected with the judgment module, and the judgment module comprises a parameter judgment module, a parameter library, a problem judgment module, a positioning module and a feedback module. And the problem judgment module judges whether the switch machine operates normally or not when switching the turnout based on the wavelength parameter and the working state. According to the invention, when the switch machine switches a turnout, the central wavelength of the strain gauge of the fiber grating stress sensor on the action connecting rod or the locking rod is reduced or increased, the fiber grating demodulator receives and demodulates the change of the wavelength through the optical cable, and the industrial personal computer monitors the program to process and store the change of the wavelength. And parameters such as the magnitude and direction of the conversion force, the conversion speed and the conversion time are output on the display, so that online real-time monitoring is realized, and the actual situation of a real monitoring site can be quickly fed back.

    本发明公开了一种光纤光栅道岔转换锁闭力监测系统,涉及转辙机监测技术领域,包括光纤光栅道应力传感器和判定模块,所述工控机还连接有判定模块,所述判定模块包括参数判断模块、参数库、问题判定模块、定位模块和反馈模块,所述问题判定模块基于波长参数及工作状态判断转辙机转换道岔时是否正常运作。本发明,转辙机转换道岔时,动作连接杆或锁闭杆上的光纤光栅道应力传感器的应变片中心波长减少或增大变化,光纤光栅解调器通过光缆接收到波长的变化并解调,工控机监测程序对波长的变化进行处理、储存,在显示器输出转换力大小和方向、转换速度、转换时间等参数,由此实现在线实时监测,有利于快速反馈真实的监测现场的实际情况。
