Segmented concealed buried pipeline cathodic protection status monitoring and early warning system and method

Abstract

The invention relates to a segmented concealed buried pipeline cathodic protection state monitoring and early warning system and method. The system includes a monitoring management center, a standard pile and a solar power generation device. The monitoring management center includes a cloud service terminal and a remote control device connected by communication. terminal, mobile phone APP and computer, wherein the standard pile and the solar power generation device are connected to each other and set up in two parts on the ground level. The standard pile includes interconnected standard pipe sections and standard columns. The column moving mechanism is equipped with a motor on the quasi-column fixed mechanism, and the main shaft of the motor is meshed with a rack provided on the standard column moving mechanism through a gear. The standard pipe section realizes segmental monitoring of buried pipeline cathodic protection, reduces interference of different pipe sections in the pipeline, and weakens pipeline corrosion. Compared with the prior art, the present invention has the advantages of safely and efficiently obtaining the cathodic protection state parameters of the buried pipeline in sections, and can monitor and warn in time.

Description

technical field [0001] The invention relates to the related technical field of cathodic protection monitoring of buried pipelines, in particular to a segmented concealed buried pipeline cathodic protection state monitoring and early warning system and method. Background technique [0002] With the increase of oil and gas users, the total demand for oil and gas continues to grow. In order to meet the needs of the society, new oil and gas pipelines are constantly being built, and the pipelines that have been put into operation have increased year by year. With the increase of pipeline operating mileage and service life, due to external factors such as soil environment, railway, subway, high-voltage lines, underground pipe network and other external factors, accidents such as corrosion, fracture, perforation, explosion and other accidents of buried pipelines occur from time to time. State property caused immeasurable losses. [0003] At present, such as the existing patent "A...

Problems solved by technology

[0003] At present, such as the existing patent "A Distributed Potential Monitoring System for Cathodic Protection of Long-distance Pipelines (CN110144592A)", this patent only monitors the potential of the cathodic protection system of the entire pipeline, and cannot monitor the potential, current density, sacrifice Anode corrosion degree and other data; Another example is the patent "A Buried Pipeline Operating Environment and Corrosion State Monitoring System (CN 103389130A)", which can monitor the corrosion environment and corrosion state of the operating pipeline, but cannot monitor the pipeline cathode potential, corrosion Current and other information, lack of early warning processing module, lack of consideration of human factors to damage the system protection
