MODERN SYSTEM FOR SHIP ENGIN CONTROL USING PLC

Automatic control is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, steering and stabilization of ships, aircraft and other application with minimal or reduced human intervention. Now days all processes have been completely automated. After fixed interval continuous monitoring and inspections are required for ship. There are possibilities of errors at various stages of measurement and inspection due to human error and also the lack of features of microcontrollers. In this paper we are controlling the various parameters such as fuel level, RPM, water and lube oil temperature etc. with the help of PLC (programmable logic controller) and HMI(human machine interface) to control the other parameters accordingly. The main objective of this system is to monitor and control the various parameters in the ship Engine where human cannot access, for that purpose we had discussed this idea with power control engineers and they provide necessary information.This system includes the feature which set the alarm to notify the operator if any of the monitored values exceeds their normal operating ranges as defined by set points.
