An Embedded Remote Monitoring System for Cathodic Protection

Abstract

The cathodic protection remote monitoring system is a circuit senses the measured voltage used to protect metallic structures against corrosion and display it locally at the field and then transfers it to monitoring room. In this research, two microcontroller-based subsystems have been designed: the field and monitoring sides. These two subsystems are connected together by two wireless Xbee modules. To design and simulate this proposed system, a Proteus ISIS simulator and ATMEL studio software have been used. The monitoring side is equipped with alarming Light Emitting Diodes (LEDs) to monitor the in-range, over and under protection ranges according to NACE standard. The simulated and implemented results were coincided, display and wireless communication were done in high accuracy and the alarm has been activated when the sensed value was out of protection range.
