Optical Fiber Bragg Grating Ground Settlement Monitoring System Based on 4G

Fiber Bragg grating sensors are often used to monitor ground settlement. However, there are some problems that cannot be ignored, such as the poor intuitive performance of monitoring results, the weak comprehensive management function, incapable of sharing remote data. In order to solve the problems mentioned above, a fiber Bragg grating remote monitoring system for ground subsidence based on 4G network has been designed. The system structure is a hybrid of two tier C/S and three tier B/S, applying virtual instrument technique to develop front end data acquisition software, adopting asp.net and C# language to develop the website, while using Android to develop mobile phone terminal APP. Those laid a good foundation for monitoring real-time data. At the same time, remote data transmission make use of 4G network, compared to the GSM/GPRS, it effectively improves the data transfer speed and accuracy. The system contained collection and management of monitoring data, real time dynamic display of monitoring result, remote access control and alarm monitoring. So that the functions are gathered in the integral whole to realize intelligent and networked management of ground subsidence monitoring. In the process of monitoring the ventilation shaft wall in a coal mine, the system runs well and provides a powerful guarantee for safety production of coal mine.
