Application scenarios

Broken wire monitoring: Monitor possible wire breakage in prestressed steel cylinder concrete pipes (PCCP).

Intrusion warning: Monitor buried pipelines that may be damaged by third parties in the form of ground excavation, pile foundation construction, survey construction, and underground excavation construction.

Uneven settlement monitoring: Monitor the uneven settlement or large deformation of pipelines caused by geological disasters such as pipeline burying and tunnel construction, as well as landslides and other geological disasters.

Leak monitoring: Monitor large leaks that may occur along the entire pipeline, including sudden leaks and persistent leaks. Locate leaks. Helps quickly lock leak points and reduce leakage.

Monitoring principle

Environmental disturbances around the optical fiber will cause changes in the fiber core parameters such as fiber length, diameter, and refractive index, further modulating the backscattered light, resulting in changes in the intensity, phase, frequency, etc. of the scattered light. By establishing the connection between disturbance events and optical signals, the identification and location of disturbance events can be achieved. The AI ​​deep learning neural network algorithm is used to improve the accuracy of identifying broken wires and third-party intrusion events, and reduce the rate of false positives and false negatives. It can be combined with the UAV linkage platform to carry out "early warning-exploration" integrated management and control. For PCCP, the safety margin after wire breakage can be evaluated in conjunction with the PCCP structural risk assessment system.

Technical indicators

The system consists of optical cables laid along with the pipeline, monitoring hosts with different functions, and control center software and hardware systems.

Optical cable: Different types of optical cables are selected according to different monitoring events (such as vibration and strain) and monitoring principles; the laying method inside the pipe or outside the pipe is selected according to the characteristics of the monitoring event and deployment conditions.

Monitoring host: Monitoring hosts with different functions are selected according to different monitoring events (such as vibration and strain). Commonly used ones include vibration monitoring host, sound restoration monitoring host, strain monitoring host, temperature monitoring host, etc.
