Design And Implement Of Slope Monitoring FBG Sensing System Based On Linux

With the development of FBG application in slope monitoring, traditional FBG sensing system has a difficulty to meet the requirements of slope monitoring. According to these requirements, a FBG sensing system based on Linux which is suitable for slope monitoring is designed, optimized and implemented in this paper.The functional and performance requirements of system according to slope monitoring are made first. Then the deployment scenarios and sensing laws are studied. According to the above, the photoelectric system which include system configuration, sensor networking and demodulation analysis program is designed and optimized. The optimization in demodulation analysis program is tested in a simulation. The overall design of FBG sensing system is implemented in this way. On the basis of above, through the implementation of hardware, operating system, device drivers and software, an embedded system based on Linux is implemented, which supports complex signal detecting, processing and touch-screen display, intelligent warning and networking transmission in FBG sensing system by the powerful Linux system innovatively. A complete sensor system which can monitor the slope security situation and meet its requirements is implemented in this way.Through experimental verification, the FBG sensing system can monitor the slope security situation and meet the functional requirements of visual interactive intelligent and remote monitoring. The precision is improved effectively through the optimization in demodulation analysis program, and the three mutual restraint performances including sensor capacity, processing speed and monitoring precision are improved innovatively at the same time, which meet the performance requirements of slope monitoring. In summary, a slope monitoring FBG sensing system based on Linux is implemented in this paper.
