Optimization of remote monitoring of cathodic protection power supply system base on four-tier structure and B/S model

Cathodic protection power supplies are widely used for corrosion prevention on storage tanks, transmission and distribution pipelines in the gas and petrochemical industry. To improve reliability of the cathodic protection systems, a remote monitoring of power supply system base on four-tier structure and B/S model is developed This paper presented four-tier structure: Acquisition unit control scheme with MSP430F2013 as controller, Digital control unit control plan with dsPIC33FJ16GS504 as core chip, GPRS communication unit adopts processor LPC2134 (ARM7) and SIM300, Monitoring center design plan with JAVA as programming language, and B/S model as well.
