An in-situ automatic monitoring system and method for underground sewage pipeline leakage

Abstract

The invention relates to a system and a method for automatic in-situ monitoring on leakage of an underground sewage pipeline. The system provided by the invention comprises an upper computer for controlling and a resistivity feeler lever the bottom of which is provided with a cone head, the resistivity feeler lever is formed by splicing at least 5 pluggable nylon modules and copper pole rings which are clamped in the butt seam of two adjacent nylon modules, sliver is plated on the inner and outer surfaces of the copper pole rings, and the top of the resistivity feeler lever is provided with acollection control circuit and a wireless data transfer module; the collection control circuit comprises a control program and is connected with the copper pole rings by virtue of wires; a public network server and client software are matched with the wireless data transfer module. The monitoring method comprises the following steps: burying or penetrating a monitoring point positioned on the underground sewage pipeline into the resistivity feeler lever; and controlling the system to operate and automatically alarm when the leakage reaches the threshold by virtue of client software. The system and method provided by the invention integrates the functions of automatic collection, remote transmission, data storage, intelligent processing, automatic alarm and remote control, is simple to useand high in automaticity, and can be used for overcoming the defect on the real-time performance and accuracy of traditional methods.

Description

technical field [0001] The invention relates to an in-situ automatic monitoring system and method for leakage of underground sewage pipelines, belonging to the field of pollution prevention and control. Background technique [0002] With the development of society, urban sewage pipelines and industrial sewage pipelines are becoming more and more dense. Affected by the service life and other factors, sewage pipelines will have leakage problems, resulting in sewage leakage, affecting the surrounding environment and even causing pollution accidents, so the monitoring of pipeline leakage is becoming increasingly important. [0003] Since the sewage pipeline is a non-pressurized pipeline, it is not suitable for the commonly used pressure monitoring method. At present, the monitoring of sewage pipeline leakage is often based on whether the leaked sewage is found. When a leak is found, conduct a survey of the contaminated area. Another method is to carry out laboratory analysis ...

AI Technical Summary

Problems solved by technology

Another method is to carry out laboratory analysis after sampling near the pipeline. The analysis of pollution degree is accurate but inefficient

None of these methods can detect the leakage source at the initial stage of pipeline leakage, and there is still a lack of a method that can automatically monitor the leakage point and degree of underground sewage pipelines
