基于光纤光栅传感器的弓网状态监测方案及其验证试验

Monitoring Scheme and Verification Test of Pantograph and Catenary Based on FBG Sensors

结合轨道交通列车受电弓与接触网安全监测的实际需求,提出利用光纤光栅传感器进行碳滑板应变变化实时检测,利用应变推导出接触力变化,实现接触力检测,从理论模型和试验测试两方面对监测可行性进行验证,为弓网状态监测提供了一种可行的解决方案。

According to the actual demand of railway pantograph and catenary safety monitoring,this paper puts forward the strain test with fiber Bragg grating sensor for real-time detection of changes in carbon slide strain-The contact force is measured by deriving the change of contact force from the strain.The scheme of monitoring pantograph and catenary contact state is introduced,and the feasibility of the scheme is verified from theoretical model and practical test,which provides a feasible solution for pantograph and catenary state monitoring.
