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.
