Pipeline leakage checking system

Abstract

The invention discloses a pipe leakage detecting system, comprising a controller and a pipe leak detector, wherein, the controller processes and store data in the pipe leak detector through a wireless technology; the pipe leak detector also comprises a sensor, an amplifier, an analog-digital conversion module, a main processor, a GPS clock synchronization control module, a wireless communication module and a power supply module, wherein, the sensor is arranged on a pipe to be detected; the amplifier is connected with the sensor; the analog-digital conversion module is connected with the amplifier; the main processor is connected with the analog-digital conversion module; the GPS clock synchronization control module is connected with the main processor; the wireless communication module is connected with the main processor; and the power supply module is connected with the main processor. In the invention, sensors are arranged on the outer wall of the pipe at intervals and receive sound waves produced by leakage points on the pipe under the condition that GPS time service error is less than 200nS, thereby realizing high sensitive detection of the pipe leakage and high precise positioning of leakage sources. In addition, the pipe leakage detecting system is characterized by low cost, small volume, light weight, being portable and convenient operation.

Description

technical field [0001] The invention relates to the field of pipeline transportation, in particular to a pipeline leakage detection system for detecting pipeline leakage. Background technique [0002] Pipeline transportation is one of the five major transportation industries alongside railways, highways, water transportation, and shipping. As a special equipment, it is more and more widely used in various industrial fields such as petroleum, chemical industry, fertilizer, electric power, metallurgy, light industry, and medicine. City gas, heating systems, and almost all fluids use pressure pipes in their production, processing, transportation and use. According to a report in 1998, there are currently more than 2.3 million kilometers of long-distance pipelines in the world. The United States has 960,000 kilometers of long-distance pipelines and 1.96 million kilometers of gas pipelines in cities. According to statistics in 2002, there are more than 30,000 kilometers of long-...

AI Technical Summary

Problems solved by technology

City gas pipes are often buried underground, making leak detection difficult

If the leakage is not detected and stopped in time, it will not only cause energy waste and economic loss, but also cause catastrophic accidents such as explosions, fires, and environmental pollution, resulting in huge losses of life and property.

However, at present, our country is very backward in the detection and monitoring technology of urban buried gas pipelines. In terms of leakage detection, there is no technology and equipment that can quickly determine the leaking position of buried pipelines. Once some pipelines leak, it often takes a lot of material and manpower. and time to find the leak point, bringing accident hazards to the safe operation of the pipeline
