Design and implementation of the remote control of ICCP systems

Impressed current cathodic protection (ICCP) technology is a common method for protecting ships and bridges from corrosion. A color touch screen is connected to ARM LPC2138 on the ICCP master control panel through serial ports. Communications between ICCP systems and the arm processor of remote terminals are realized using Modbus protocol. The touch screen is utilized for real-time online monitoring and a real-time database is built using RS485 communication interface for users convenience. In receiving the response frames, predictions are strictly checked with the frames received to avoid any fault. The result shows the efficiency of the system.
