Objective
◆ The surface potential of steel structures is an important indicator for assessing the cathodic protection status of steel structures.
Working Principle
◆ The reference electrode is installed at various locations on the steel structure to monitor the surface potential at representative points.
◆ The potential signals acquired by each reference standalone unit are centrally transmitted to the CP monitor for data storage, transmission, analysis, and other functions.
◆ The potential data measured by the monitoring instrument are transmitted to the host computer via the RS485 communication bus;
◆ The computer processes the potential data from each monitoring point, displays the potential measurement curves, and saves the potential data to the database.

Cathodic Protection Monitoring and Assessment System Based on Multi-Data Fusion
▎Key Software Features
Working Principle
◆ Real-time monitoring and display of parameters such as steel structure potential/current density, sacrificial anode current, and remaining service life of sacrificial anodes;
◆ Achieve three-dimensional visualization of the protection status, with real-time display of under-protected and over-protected areas;
◆ While providing feedback on the cathodic protection status of the steel structure, it can also serve as an input signal for the ICCP system, enabling closed-loop regulation of the auxiliary anode current output and thereby establishing a closed-loop monitoring and control system for the ICCP.
◆ Highly automated data acquisition, analysis, fault alarm, and over/under protection pre-warning functions;
◆ Features historical data and log query and analysis capabilities, customizable data filtering, and automatic generation of formatted reports and dashboards;
◆ Multi-terminal remote access, centralized control via a central control system, shore-based remote control, and remote diagnostics by technical experts.
