The invention relates to an intelligent constant potential rectifier control module. The intelligent constant potential rectifier control module comprises a central processing unit, a relay unit, an analog quantity acquisition unit, an analog quantity output unit and a communication unit, wherein the relay unit is connected with the central processing unit; the relay unit comprises two relay circuits which are correspondingly used for being connected to the two ends of a power supply starting-stopping switch and a work mode switch of a constant potential rectifier in parallel to control switching of the power supply starting-stopping switch and the work mode switch; the analog quantity acquisition unit is connected with the central processing unit, and is used for being connected with theconstant potential rectifier to collect a cathodic protection potential; the analog quantity output unit is connected with the central processing unit, and is used for being connected with the constant potential rectifier to control voltage output of the constant potential rectifier; and the communication unit is connected with the central processing unit, and is used for communicating with the outside. The power supply starting-stopping and the work mode are automatically controlled, the output signal amplitude of the constant potential rectifier is controlled by a pipeline potential measuredby a cathodic protection pile, pipeline a cathodic protection closed-loop control is realized, and the situation that the equipment is damaged or pipelines are not within a protection range due to too large or too small output fluctuation of the constant potential rectifier is avoided.
Description
technical field [0001] The invention belongs to the technical field of potentiostat intelligent control, and in particular relates to a potentiostat intelligent control module, a control system and a control method. Background technique [0002] The cathodic protection system is widely used in oil and gas buried steel pipelines. Failure of the cathodic protection system may cause corrosion and perforation of oil and gas steel pipelines. Since the medium transported by oil and gas pipelines is flammable and explosive, once leakage occurs, it often causes property damage. The loss and environmental pollution will lead to serious casualties and cause adverse social impact. [0003] In the existing cathodic protection system, the output adjustment of the potentiostat is often adjusted through the signal feedback of a single point, and the place outside the signal feedback point of the protected structure cannot be guaranteed to be protected by the cathodic protection in time, re...
