Method and system for monitoring leakage of urban underground pipe network

Abstract

The invention discloses a city underground pipe network leakage and loss monitoring method and system. The system is achieved by installing a sensor on a pipeline. The method comprises the steps thatthe sensor collects t second signals every s seconds, and M groups of signals are formed in total; equivalent amplitude of each group of signals is calculated and converted into decibel as expression;according to distribution of equivalent amplitude decibel values, the actually measured bandwidth of the M groups of signals is calculated; in the M groups of signals, the equivalent amplitude decibel value with the largest number of samples serves as actually measured intensity of the signals; the datum intensity and the datum bandwidth when the pipeline does not leak are set, and the actually measured intensity and bandwidth are compared with the datum intensity and bandwidth; when the conditions that the actually measured intensity is larger than the datum intensity and the actually measured bandwidth is smaller than the datum bandwidth are met at the same time, leakage of the pipeline is judged; or else, it is judged that the pipeline does not leak. The monitoring system is simple instructure, low in cost and high in implementability, and has real-time monitoring performance.

Description

technical field [0001] The invention relates to a pipeline detection technology, in particular to a real-time monitoring device and method for the leakage of an urban underground pipeline network, and in particular to a method and system for monitoring the leakage of an urban underground pipeline network. Background technique [0002] Urban underground pipelines undertake the functions of transporting energy, resources and transmitting information, and are important underground infrastructures. my country's urban underground pipe network generally has problems such as aging or deterioration of facilities, lack of information, etc. Pipeline leakage and accidents occur frequently. Therefore, pipeline inspection technology plays a pivotal role in maintaining the safe operation and information management of pipeline networks. [0003] At present, the domestic pipeline network leakage monitoring technology level and equipment intelligence are low, relying heavily on the experien...
