Abstract:At present, the judgment of the crew on the condition of the ship and the condition of the ship is mainly depended on the experience. It is inevitable that there will be an inappropriate decision, resulting in the loss of human and financial resources. For this reason, A monitoring system of marine engine room is proposed and developed, which is integrated into the relative principal component analysis. Besides conventional monitor and control functions, the system can realize fault monitoring function. Assist the manager in the analysis of the system failure, to better ensure the safety and efficiency of navigation of ships, reduce artificial misoperation accident problem. Enhanced the function of the ship monitoring system, greatly improve the staff's work efficiency and reduce the labor intensity of the staff. It is designed to satisfy the regular operation of the class society, which provides a new way for the design of the engine room monitoring control system.
