A compact remote switching with efficient monitoring for AC plants: Project work undergoing at "Prasar Bharathi All India Radio Chennai"

Remote monitoring has been implemented in many areas. This paper introduces its specific application to air-conditioning plant control and monitoring using PIC Microcontroller. Remote monitoring and intelligent maintenance is one of the most important criteria for maximizing production and process plant availability. Initially switching and monitoring were done through manually and the control switches and level monitoring unit were placed at separate places. Due to this, we cannot monitor all units at a time. In our proposed system, remote switching and monitoring is done in the control room itself. Majority of industries use distributed control system for high reliability, improve response time, improved operator interface to plant, improved accessibility of plant data.
