Abstract
Abstract
The accuracy of straightness monitoring of scraper conveyor seriously restricts the development of unmanned mining technology in underground coal mines. Fiber Bragg Grating sensors have the characteristics of passive intrinsic safety and have broad application prospects in coal mine underground monitoring technology. In this paper, the motion characteristics between two adjacent scrapers of the scraper were fully analyzed, the mathematical expressions were illustrated, furthermore, we designed and manufactured a 3D vector sensor using FBG sensors. The calibration and testing of the appropriate amount of sensor was realized, and the test results showed that the fiber vector sensor we designed can be used to measure the straightness of the scraper conveyor.
