Embodiment Construction

[0043]In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044]Such asfigure 1 ,Figure 5As shown, this embodiment provides a cathodic protection device for buried long-distance pipelines based on STM32 single chip microcomputer. An anode ground bed 101 and a reference electrode 102 are laid in the soil beside the buried long-distance pipeline 10, and the buried long-distance pipeline 10 There is a cathode connection point 104 and a zero connection point 105. In the actual project, the cathode connection point 104 is welded to the pipeline by thermite, and the solder joints are anti-corrosion by using a patch. The zero connection point 105 is also thermite welded to the pipeline, and the s...

Abstract

The invention discloses a buried long distance pipeline cathode protection device based on an STM32 single-chip microcomputer. The device is characterized in that an anode ground bed and a reference electrode are laid in the soil beside a buried long distance pipeline, and a cathode wiring point is arranged on the buried long distance pipeline; the device comprises an upper computer, a main control module, an AD data acquisition module, a DA control module, a communication module, a storage module, an RTC module, a human-computer interaction module, a power module and a temperature sensor. Compared with the prior art, the main control module acquires output voltage, output current and reference potential through the AD data acquisition module, the temperature of the pipeline is collected by the temperature sensor, the output voltage of the power module is automatically adjusted through the DA control module, and the corrosion rate of the buried pipeline is greatly reduced.

Description

Technical field[0001]The invention relates to the technical field of buried pipeline cathodic protection devices, in particular to a buried long-distance pipeline cathodic protection device based on STM32 single chip microcomputer.Background technique[0002]The corrosion problem of buried long-distance pipelines has become increasingly prominent, which brings great challenges to corrosion control. The reference potential is an important basis for judging the corrosion protection of buried long-distance pipelines. Collect the output voltage, output current, the reference potential of the pipeline to the ground, and the pipeline temperature through the cathodic protection device. According to the collected and recorded data, the protection of the pipeline can be effectively analyzed.[0003]Currently, the adjustment of the cathodic protection potential in the prior art requires manual rotation of the voltage regulator handwheel to change the output voltage until the actual voltage is con...
