The Research Of Real-time Monitoring System For Underground Engineer Based On BOTDR

This article is a sub-topic of Ministry of National Education Project "The Practice and Performance Research of Communication Integrated Training System for Experiment," item number is JZW20080 .As our existing security protection means of underground mining project are not perfect enough, despite all prospecting, exploration and other early detection methods, but it is still no guarantee that real-time underground construction excavation safety, accident will appear in the construction, such as throw , collapsed suddenly in water, Chung sand and so on. In addition, traditional monitoring methods is tunneling while measureing and remove mobile testing tool, it will use time-consuming and laborious and can not be an overall real-time measurement and long-time monitoring.The real-time monitoring system of underground engineer based on BOTDR technology presented in this paper is for solving practical problems towards real-time monitoring. The real-time monitoring system of underground engineering based on BOTDR technology is composed of three main sub-component, data collection terminals, data transmit terminals and data processing terminal. Data collection terminal is mainly responsible for data collection, and then wirelessly transmitted to our data transmission terminals, and then the data from the terminal is send to the surface of the data processing terminal for analysis and processing.This article complets the form of a small wireless network from sensor to the transmission equipment, and successfully uses the BOTDR technology to achieve the real-time sensing pressure experimental test of light into the ring, and uses the light into the ring for transmitting signal we have collected. This study has great practical significance for the safety of underground works.
