The invention provides a cathode protection data processing method and device. The method comprises the following steps: obtaining a corrosion risk grade of a pipeline; establishing a multi-dimensional corresponding relationship based on a test pile, wherein the multi-dimensional corresponding relationship comprises a corresponding relationship between the test pile and equipment of a cathode protection system, a corresponding relation between the test pile and a pipeline laying environment influencing the corrosion risk of the pipeline, a corresponding relation between the test pile and operation parameters of the cathode protection system, and a corresponding relation between the test pile and a pipeline corrosion analysis result; and determining a corrosion factor of a target pipeline according to the multi-dimensional corresponding relationship, wherein the target pipeline is a pipeline with a corrosion risk grade greater than a preset threshold. According to the embodiment of theinvention, the multi-dimensional corresponding relationship is established on the basis of the test pile, and the corrosion factors influencing the pipeline corrosion can be accurately, conveniently and quickly determined according to the multi-dimensional corresponding relationship.
Description
technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for processing cathodic protection data. Background technique [0002] Existing steel pipelines for transporting oil, natural gas and other gases and liquids are usually buried underground, and the soil environment in which they are located may be relatively complex, so corresponding anti-corrosion measures need to be installed to prevent pipeline corrosion. Existing pipeline anticorrosion is mainly achieved by means of anticorrosion layer and cathodic protection. Among them, the principle of cathodic protection is to provide a protective current through a potentiostat or a sacrificial anode, so that the protected steel pipe acts as a cathode, inhibiting electron migration and preventing metal oxidation. In the specific work process, the effectiveness of cathodic protection needs to be tested. The result of cathodic protection effectiveness detection ...
