Gas pipeline leakage point detection device and detection method

Abstract

The invention discloses a gas pipeline leakage point detection device and a detection method, and relates to the field of gas pipeline detection. The gas pipeline leakage point detection device comprises a sensor module, a data transmission module, a fixed IP line, a server, a gas pipeline leakage alarm management system and a management computer. The sensor module acquires flow data, pressure data and infrasonic wave data of a gas pipeline. The data transmission module is connected with the sensor module. The fixed IP line is connected with the data transmission module. The server is connected with the fixed IP line, and the flow data, the pressure data and the infrasonic wave data are uploaded to the server through the data transmission module and the fixed IP line. The gas pipeline leakage alarm management system is installed in the server, receives, calculates and analyzes the flow data, the pressure data and the infrasonic wave data, shows the gas running state and gives an alarm.The management computer is connected with the server and used for managing the gas pipeline leakage alarm management system. By the adoption of the gas pipeline leakage point detection device and thedetection method, gas feature graphs of different road sections are provided, the number of influence factors such as the environment is reduced, the false alarm rate of gas alarms is reduced, and the detection accuracy and the alarm efficiency are high.

Description

technical field [0001] The invention relates to the technical field of gas pipeline detection, in particular to a gas pipeline leak detection device and detection method. Background technique [0002] As the cleanest energy among fossil fuels, natural gas has the advantages of high heat and high energy efficiency, and is regarded as the most promising emerging high-efficiency energy. Pipeline transmission has become the first choice for natural gas transportation due to its advantages of low cost, safety and airtightness, large transportation volume, guaranteed quality, and easy control and management. However, natural gas is flammable and explosive. Once a pipeline leakage accident occurs, it may cause a series of disasters such as explosion, fire, poisoning, and environmental pollution. If it occurs in a residential area, it will cause more serious harm. The causes of natural gas pipeline leakage mainly include external force damage, corrosion and aging of materials and e...

Problems solved by technology

[0019] Due to the complex environment of urban underground gas pipelines, there are many on-site interference situations, and the alarms generated by different pipeline materials, different diameters, pressures, etc. False positive rate and missed positive rate

[0020] In recent years, accidents caused by urban pipeline network leakage have occurred frequently. The existing detection technology is difficult to meet the growing needs of the development of the natural gas industry. It is urgent to study a rapid detection scheme for gas leakage, which has great social significance for reducing the occurrence of accidents.
