MONITORING TECHNOLOGY


Monitoring Principle

The safety monitoring system based on distributed optical fiber sensing can be applied to the four fields of intrusion early warning, leakage monitoring, broken wire monitoring and settlement measurement, which can effectively capture the events that threaten the safety of the pipeline, and accurately locate them. At the same time, it can identify the event type and evaluate the hazard level of the event. It provides a reliable solution for real-time monitoring and regular detection of pipeline safety.


The system is jointly developed by our company and Tianjin Precision Testing Company. It has the technical advantages of real-time response, accurate positioning, online analysis, classification early warning, data backtracking, safety and reliability, etc. At the same time, the system functions support flexible customization, and some or all functions can be selected according to customer needs.
