Mountain area pipeline strain on-line monitoring system and method

Abstract

The invention discloses a mountain area pipeline strain on-line monitoring system and method. The safety system comprises a strain gauge, a strain collector, a signal controller, a network camera, a wind-solar complementary power supply and on-line monitoring software. The whole system comprises four pairs of strain gauges, each pair of strain gauges is divided into an axial strain gauge and an annular strain gauge, the strain gauges are installed at two positions on the pipeline, the distance between the two positions is 1km, the system adopts a solar panel and a wind driven generator to generate power, the strain collector and the online monitoring software collect and process data once every 20s, the online monitoring software dynamically displays and analyzes the strain of the pipeline, and meanwhile, a network camera is carried, and external environment factors causing strain mutation are analyzed. According to the invention, real-time dynamic monitoring and analysis of the safety state of the pipeline in the mountainous area can be realized.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline structure health monitoring, in particular to an on-line monitoring system and method for pipeline strain in mountainous areas. Background technique [0002] The geographical location of pipelines in mountainous areas is special. It needs to pass through mountains and cross rivers along the route. Natural disasters faced by pipelines in mountainous areas include landslides, geological subsidence, earthquake debris flows, etc. The occurrence of these disasters is very random and repetitive, and once they occur, they will cause great harm to the safety of the pipeline itself. In actual engineering, according to production safety requirements, regular inspections must be carried out on pipelines to find out the working conditions of pipelines in time. However, for pipelines in mountainous areas, due to the complexity of the roads, it is almost difficult to achieve high-frequency line in...

Problems solved by technology

However, for pipelines in mountainous areas, due to the complexity of the roads, it is almost difficult to achieve high-frequency line inspection along the pipeline. To solve this problem, domestic and foreign pipeline companies have taken various measures, such as using drones to patrol along the line, but limited to the form , it is impossible to truly grasp the safety status of the pipeline. Based on this, starting from the stress-strain perspective of judging the essence of pipeline safety, the stress-strain parameters can be continuously grasped in real time, and the real-time pipeline safety status
