Abstract

The invention discloses an intelligent cathode protection system based on LoRa spectrum spread communication and belongs to the technical field of anti-corrosion cathode protection of metal materials.The intelligent cathode protection system based on LoRa spectrum spread communication comprises a main monitoring station, a protection direct-current power supply, multiple wireless testing piles and multiple reference modules; the main monitoring station is connected with the protection direct-current power supply through a TCP / IP protocol or a Modbus protocol based on an RS485 serial port andsends a configuration adjustment instruction to the protection direct-current power supply; and the wireless testing piles are connected with the main monitoring station through LoRa wireless communication. In the intelligent cathode protection system based on LoRa spectrum spread communication, a LoRa spectrum spread wireless communication technology is adopted for the wireless testing piles andthe main monitoring station, and the problem that existing wire communication lines are difficultly laid and maintained is solved. Since actual connection lines are reduced, the pressure drop caused by line resistance is removed, and accordingly the accuracy of measurement data is improved.

Description

technical field

[0001] The invention relates to the technical field of cathodic protection against corrosion of metal materials, in particular to an intelligent cathodic protection system based on LoRa spread spectrum communication. Background technique

[0002] As metal materials are more and more widely used in industry, metal materials in a large number of applications are in electrolytes that are prone to electrochemical corrosion for a long time, such as soil, water, and places that are not easy to maintain, such as buried, underwater . In addition to the need to coat the anti-corrosion layer before the material is installed and laid, cathodic protection is often used to prevent corrosion of metal materials, so as to prolong the service life of industrial equipment and reduce losses. Among them, the impressed current type cathodic protection is the main one.

[0003] At present, in the impressed current type cathodic protection system, low-resistance shielded wires ar...
