Intelligent Acutator Management System

Abstract: The project is mainly developed for the industrial plants such as thermal plant, waste water treatment, refineries to get the necessary outcome the flow of liquids where regulated accordingly by the means of control valves in actuator. The flow of stream or liquid is controlled by motor operation like closing or opening the valve by the means of electrical system. All the MOVs are being controlled from UCB (Unit Control Board) as a remote operation. To control and monitor all the operation a bunch of cables have been laid between control valve and control room also it’s a time consuming work. To avoid or reduce the down time of the equipments during this situation modification is proposed to meet the above requirement (control and monitoring) an Embedded Based Intelligent Control Module is developed. For each actuator there will be one control module. All the modules can be multi dropped and linked to the main system. Any actuator can be operated or monitored from the control/monitoring mimic. The main system and the other individual slave systems are linked with a single 2 core communication cable using RS485. The total control commands and parameter monitoring will be communicated (as a to and fro) through this cable only. Due to this modification we could save many numbers of cables and reduce the downtime of the equipment during the emergency situation. The necessary virtual control panel will be developed on VB platform.
