Description
Summary:A kind of ground deformation monitoring device with Fiber Bragg Grating (FBG) as the basic sensing device is specifically designed, and the wireless network technology is introduced to form a remote monitoring system, which consists of single chip microcomputer, hardware and software design integrating ZigBee and GPRS, to overcome the difficulties and deficiencies of traditional mine geological disaster monitoring technology. The fiber grating sensor distributed in the terminal is used to measure the ground deformation of goaf in real time, and the monitoring data are collected to the coordinator node via wireless communication and finally transmitted to the upper computer through GPRS module. Featured by low cost, high reliability and easy networking, this monitoring system reduces the cost of the wireline equipment due to wiring and can automatically and remotely monitor the wide-range ground subsidence area in the mine goaf. It is shown through the practical application in monitoring of the goaf in certain iron mine in Zibo that this monitoring system has reliable performance, high monitoring accuracy and good monitoring results.
