Figure 1 Schematic diagram of the ship shore integrated monitoring system structure

As shown in the following figure, the hardware configuration of the energy consumption and shipping management system mainly includes the driver's cab control panel, central control room control panel, monitoring cabinet, energy consumption analysis and data transfer station, switch, firewall, and on-site instruments and meters (including flow meters, shaft power meters, etc.). The software configuration includes the driver's cab control panel software, central control room control panel software, energy consumption analysis and data transfer software, and shore based remote management analysis software, And PLC controller program. The monitoring cabinet communicates with the cabin monitoring alarm system, liquid level telemetry system, navigation system, and other systems or equipment with data input and output requirements (Modbus TCP/RTU) to collect real-time data from these systems or equipment. At the same time, on-site instruments and meters (shaft power meters, flow meters, etc.) transmit the collected real-time data to the monitoring cabinet through hard wires (4-20mA). The monitoring cabinet calculates and processes the collected real-time data, and transmits it to the energy consumption analysis and data transfer station through Modbus communication (Modbus TCP/RTU). The transfer station stores real-time data, historical data, and logs of the system, and conducts energy consumption and energy consumption analysis, emission analysis, navigation analysis, and navigation suggestions based on the collected data, And push the data to the client software (management analysis software) through ship shore communication (format to be determined) for data analysis and display, and synchronously store these data in the cloud database. The cockpit control panel can set fuel consumption or speed. After setting, the system can adaptively and automatically optimize propulsion power based on real-time collected information such as speed, draft, and sea conditions, and control the output of the optimization results to reduce navigation fuel consumption.
