Optical Fiber Sensing Coal Mine Roadway Deformation Monitoring System Based on Internet of Things
In order to reduce the occurrence of roof accidents,this paper designs a kind of optical fiber sensing roadway defor-mation monitoring system based on Internet of things.The system realizes the integration of"sense","transmission"and"alarm",and can monitor the specific deformation of the roadway in real time and objectively.By utilizing the passive optical properties of optical fibers,the electrical safety issues of live equipment can be solved in coal mines,and this design system has been established.Through the laboratory simulation test,the monitoring system can accurately monitor the degree of roadway deformation,and has a good early warning effect on roadway deformation.The error of the monitoring system is less than 0.5%,and it has good real-time performance and accuracy,which provides a high implementaion application scheme for coal mine roadway safety monitoring.
