Distributed fiber optic monitoring technology can achieve multi parameter (temperature, external force damage) detection using a single optical cable, and can monitor the status of the entire network pipeline in real-time without blind spots. It has the characteristics of easy construction, strong anti-interference ability, and high measurement accuracy, and is a reliable and efficient solution. Selecting a distributed fiber optic temperature and vibration monitoring function module with high measurement accuracy, high positioning accuracy, and fast response, the distributed fiber optic temperature monitoring technology and vibration monitoring technology are organically combined. Real time monitoring of the temperature field and vibration signals around the thermal pipeline network is carried out through a single optical cable, and the distributed fiber optic temperature monitoring data and vibration monitoring data are uploaded to a remote real-time database through a wireless network transmission interface via software.

Pipeline leakage security perimeter system monitoring

1. By using a geographic information system, the spatial data, attribute data, equipment data, and fiber optic monitoring data of the heating pipeline network are comprehensively managed to ensure that the displayed coordinates of the monitoring data are consistent with the actual installation coordinates. Develop spatial measurement and analysis functions that can quickly provide abnormal location information in the event of leaks in the heating pipeline network or mechanical construction around the pipeline network, and make predictions and warnings on the distributed fiber optic online monitoring system.
2. For external force damage detection, develop a system learning function that automatically eliminates the influence of external environment and harsh weather, and adds normal vibrations (such as passing vehicles, pedestrians, т.б.) to the whitelist to ensure the accuracy of early warning. Select experimental points with different terrains and burial depths along the newly built pipeline network, and collect vibration waveforms of compactors, excavators, large vehicles, pedestrians, т.б., and store them in the system background for memory. When the system detects vibration signals around the pipeline network, it will automatically compare the detected vibration waves with the system stored waveforms to filter out interference signals such as pedestrians and passing vehicles, reducing system false alarms.
3. Develop system self diagnostic function to detect and alarm for fiber breakage, excessive attenuation, and other aspects, ensuring the healthy operation of the system. Сонымен қатар, establish a historical database of the pipeline network, collect real-time data and compare it with historical data for analysis, determine the health trend of the pipeline network, and predict possible problems that may occur in the future of the pipeline network.
4. By continuously injecting laser excitation signals into the optical fiber at any time through the vibration monitoring host and temperature monitoring host, storing and analyzing the returned signals, and timely pushing abnormal signals, leakage detection, excavation damage event warning, and health assessment of the heating pipeline network can be achieved.
