Design of a Wireless Remote Monitoring System for Raman Distributed-Optical-Fiber Sensing
Current wireless sensing systems based on Raman distributed-optical-fiber sensing systems are limited by technical bottlenecks such as unidirectional transmission of information and small transmission data volume.To overcome these bottlenecks,a wireless data transmission method and Raman distributed-optical-fiber temperature remote monitoring system were designed in this study.This system is based on a combination of a 4G wireless transmission module and a Raman distributed-optical-fiber sensing system.It is suitable for large-scale distributed sensing data.Results show that the proposed system displays field-monitoring results stably and in real-time in the remote control center.The bidirectional remote control of monitoring instructions was realized,and the monitoring results were analyzed.The proposed system is beneficial for reducing the cost of long-distance,real-time monitoring of distributed-optical-fiber in engineering application and improving the level of intelligent monitoring control and sensor monitoring efficiency.
