In order to reduce energy consumption, an energy consumption monitoring system is designed for the startup process of ship mechanical equipment to improve the energy consumption monitoring effect. The acquisition layer uses the collector to control the mass flowmeter and flow direction sensor to collect the energy consumption data, equipment operation data and environmental data during the startup of the ship’s mechanical equipment. The network layer uses ZigBee module and field programmable gate array controller to preprocess the data collected by the acquisition layer, eliminate obvious errors and unreasonable data, and transmit the preprocessed data to the data storage layer. The data storage layer stores the pre processed data transmitted by the network layer through the database server. The energy consumption monitoring module in the application layer presents the energy consumption monitoring results in real time by calling the data stored in the data storage layer. The energy consumption prediction module uses the gray radial basis function neural network to obtain the energy consumption prediction results according to the data stored in the data storage layer. The excessive energy consumption data is warned by the excessive energy consumption warning module to remind the driver to change the starting mode, so as to achieve the purpose of energy saving and consumption reduction. The experiment proves that the system can effectively collect and process the relevant data of the starting process of the ship’s mechanical equipment. The system can effectively monitor the energy consumption of mechanical equipment during startup and accurately predict the startup energy consumption.
