摘要
针对地铁道岔监测问题,提出一种基于光纤光栅原理的监测系统。对目前的监测手段进行比较,对基于光纤光栅应变传感器的监测系统进行阐述,对转辙机动作杆施加压力,系统测试精度达±0.1kN,有利保障地铁运行的可靠性和安全性。
Aiming at the problem of metro switches monitoring,we put forward a kind of monitoring system based on the principle of fiber bragg grating(FBG).Thecurrent monitoring methods were compared.We expatiated on the optical fiber grating strain monitoring system.We put pressure on switch pole.The system test precision could reach±0.1kN.It guaranteed the reliability and security of the subway running.
