Safety protection early warning system for buried natural gas pipeline

Abstract

The invention discloses a safety protection early warning system for a buried natural gas pipeline. The system comprises a central processing unit, an optical fiber sensing module, an environmental data acquisition module, a pipeline image processing module, a memory, a warning module, a power supply module, a wireless communication module and a monitoring terminal. According to the safety protection early warning system, the running state of the pipeline is detected in real time through the optical fiber sensing module; the environmental data around the pipeline is acquired through the environmental data acquisition module; when the leakage and sudden shock of natural gas occur, the optical fiber sensing module can be used for detecting the abnormal information of the pipeline and the position where the abnormal position of the pipeline is located; the abnormal point of the pipeline and the environmental data are marked on a pipeline image through the pipeline image processing module;meanwhile, the system is used for sending warning information and marked pipeline image information to the monitoring terminal, and thus, the on-line monitoring and safety early warning function of the pipeline are realized.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline monitoring, in particular to a safety protection and early warning system for buried natural gas pipelines. Background technique [0002] At present, with the development of the economy, the demand for natural gas is increasing day by day, and the transportation of natural gas is mainly realized through long-distance pipelines. Due to long-term disrepair, corrosion, wear and accidental damage, pipeline leakage incidents occur frequently, not only causing huge In addition, it seriously pollutes the environment and endangers human health. In order to monitor the pipeline condition, natural gas pipeline leak detection and early warning technology has emerged as the times require. The existing pipeline leak detection technologies mainly include ultrasonic detection technology, magnetic flux leakage detection technology, and eddy current detection technology. Technology, infrasonic wave me...

Problems solved by technology

[0002] At present, with the development of the economy, the demand for natural gas is increasing day by day, and the transportation of natural gas is mainly realized through long-distance pipelines. Due to years of disrepair, corrosion, wear and accidental damage, pipeline leakage incidents occur frequently, not only causing huge economic losses, and seriously pollute the environment, endangering human health, in order to monitor the pipeline condition, natural gas pipeline leak detection early warning technology came into being, the existing pipeline leak detection technology mainly includes ultrasonic detection technology, magnetic flux leakage detection technology, eddy current detection Technology, infrasonic wave method technology and negative pressure wave method technology, mainly measure parameters such as pipeline pressure and gas concentration, and the detection results can be obtained by analyzing and comparing relevant parameters of the pipeline

[0003] However, the existing pipeline monitoring technology is only a one-way measurement of pipeline parameters. Due to the special environment of buried pipelines, the detection of pipelines has not realized the online monitoring and early warning functions. In places where the technical requirements for pipeline monitoring systems are high , the above pipeline monitoring techniques are not applicable
