The cathodic protection potential acquisition system integrates intelligent potential acquisition instruments, test piles, (reference electrodes) or polarization probes, solar power supply systems, management software, etc. It achieves data transmission through wireless communication technology and Internet technology, enabling various departments of the operation management unit to perform parameter detection and equipment control of the oil and gas pipelines, oil and gas storage tanks, constant potential instruments, and other devices under their jurisdiction.Administrators with different permissions can view real-time information about equipment location, status, surrounding environment, and other conditions through an electronic map in the central control room (including intranet PCs, mobile IE browsers, etc.).Combined with the intelligent potential acquisition system, the status and faults of cathodic protection can be diagnosed, analyzed, and suggestions for treatment provided. The entire system adopts a network architecture, allowing department leaders to simultaneously view the operation status of the entire system online.
