A cathodic protection intelligent control method and system

Abstract

The invention discloses a cathodic protection intelligent control method and system. The method includes: a collection device collects cathodic protection signals of cathodic protection points, and sends the cathodic protection signals to an intelligent cathodic protection field industrial computer; the intelligent cathodic protection field The industrial computer performs digital-to-analog conversion on the cathodic protection signal to obtain cathodic protection data, and sends the cathodic protection data to the server; the server analyzes the data, considering the self-corrosion point data, resistivity, temperature, humidity, power-on The interaction among potential, power-off potential, protection / corrosion current density, AC interference current density, and AC interference current frequency, so that the fault information obtained based on the above method can accurately characterize the location and cause of the fault, thereby improving cathodic protection. Intelligent control method and system intelligence and accuracy.

Description

technical field [0001] The present invention relates to the technical field of cathodic protection, in particular to an intelligent control method and system for cathodic protection. Background technique [0002] Since the 1990s, the domestic application technology of cathodic protection has been continuously matured. Around 2000, the technical scheme of impressed current protection, supplemented by shallow-buried sacrificial anode protection, was gradually applied on a large scale in long-distance pipelines, oilfield stations, storage tanks, etc. Since 2007, the data remote transmission technology using GPS has gradually begun to develop, and the data remote transmission technology based on the Internet of Things has been applied on a large scale. In the application of the existing technology, there are mainly the following problems at present: 1. The database is managed with data as the object. Generally, only a single piece of data is collected. Due to the influence of c...

Problems solved by technology

In the application of the existing technology, there are mainly the following problems at present: 1. The database is managed with data as the object. Generally, only a single piece of data is collected. Due to the influence of construction uncertainty factors and site uncertainty factors, many collected electrical signals If it is not within a reasonable range, the cause of the abnormal electrical signal cannot be determined; 2. The electrical signal is collected at a fixed frequency, and it can only be judged whether the data is normal according to the range of normal data, and the equipment failure cannot be analyzed through the electrical signal data; 3. Due to the previous Neither (1, 2) can get an accurate answer, so an accurate alarm cannot be performed, causing the user to either frequently refresh the alarm data screen during use, or have no alarm function; thus resulting in 4. Automatic regulation of the potentiostat out of the question

Until now, there are basically no solutions in the field of cathodic protection intelligent control in the industry
