Abstract

The invention discloses a high-sensitivity water delivery pipeline leakage monitoring system and method. The system comprises a power supply module, a chaotic circuit module, a water monitoring sensor and a display module; and the power supply module, the water monitoring sensor and the display module are connected with the chaotic circuit module. The method comprises the following steps: (1) generating a chaotic system with a cross-coupling term by using the chaotic circuit module; (2) creating turbulence on the cross-coupling term of the chaotic system by using electrical signals generated by a sensor circuit module of the chaotic circuit module to cause orbital transition of chaotic attractors; and (3) monitoring leakage of a water delivery pipeline by using the water monitoring sensor, and judging conditions of leakage of the water delivery pipeline according to chaotic attractor orbits displayed by the display module. The water delivery pipeline leakage monitoring system is not limited by pipeline materials or mounting environments, and judges rapidly whether leakage exists or not according to change of the attractors; the size of a leaking part of the pipeline is recognized by a salt water monitoring technology in an assisted manner; and the high-sensitivity water delivery pipeline leakage monitoring system is simple in structure and easy to use.

Description

technical field [0001] The invention relates to the field of signal monitoring, in particular to a high-sensitivity water pipeline leakage monitoring system and method, which utilizes chaos theory to monitor the water pipeline leakage. Background technique [0002] The pipeline system plays a pivotal role in the process of water resource transportation, but the pipeline will have different forms of failure during long-term use, such as pipeline cracks, pipeline corrosion, coupling vibration of the pipeline system, water hammer in the pipeline, and valve vibration, etc. . In order to ensure the normal development of industrial production, the monitoring of pipeline leakage faults has become a problem that people pay more and more attention to. Aiming at these problems, some solutions have been proposed. Pipeline non-destructive monitoring technology, such as endoscopic monitoring method, infrared monitoring method, X-ray analysis method, magnetic particle monitoring, eddy c...

Problems solved by technology

However, this sensitivity usually needs to evolve over a certain period of time, which leads to the lack of real-time and effectiveness of Chaos’ ability to monitor abnormal signals; in addition, since the system is only sensitive to changes in initial conditions, it is necessary to continuously change Initial conditions are used to monitor abnormal signals. In the process of specific engineering practice, it corresponds to the following operations: Continuously "start-switch" the circuit to make the system operate under different initial conditions

This kind of operation is not conducive to the long-term operation of the system; second, the monitoring efficiency is low

Therefore, these intuitive and subjective ideas hinder the scientific application of chaos
