摘要: 针对用于矿井提升机钢丝绳张力测量的电子传感器存在可靠性低、抗潮能力差、寿命短等问题，设计了一种光纤光栅传感器。该传感器采用双栅结构，利用差动补偿法消除温度的影响；通过光检测装置检测光栅的中心波长偏移量，根据中心波长偏移量与压力之间的线性关系可间接推算出传感器受到的压力，即为钢丝绳张力。实验及测试结果验证了该传感器的可靠性。

Abstract: In view of problems of low reliability, poor moisture resistance and short service life existed in electronic sensor applied in steel wire rope tension measurement of mine hoist, a fiber grating sensor was designed. The sensor uses dual-gate structure, and adopts differential compensation method to eliminate impact of temperature; it uses grating detection device to detect center wavelength offsets of fiber grating, so as to calculate pressure of the sensor according to linear relationship between the center wavelength offsets and pressure, namely the tension of the steel wire rope. The experimental and test results verify reliability of the sensor.
