[0054] The data fusion module also loads the ship models and cargo models selected by the material library module according to the location of each berth, the type of cargo loaded and unloaded by the berth, and the tonnage level of the ships at the berth onto the three-dimensional port simulation model built by the model construction module. The data fusion module also loads the ship models and cargo models selected by the material library module according to the tonnage level of ships entering and leaving the port, the type of cargo loaded on the ships, and the location of the ships onto the three-dimensional port simulation model built by the model construction module.

[0055] The data display module is used to display the port multi-source information display model obtained by the data fusion module.

[0056] Specifically, the data display module can display the port multi-source information display model on different terminals, such as laptops, desktop computers, tablet computers, mobile phones and other devices.

[0057] In the above embodiment, the port multi-source information fusion display device integrates information from multiple data sources to achieve unified management and use of data and improve the integrity and accuracy of information. It supports the rapid processing and analysis of large amounts of real-time data and provides immediate decision support for port operations.

[0058] In another embodiment, each cube represents a container, and the bulk cargo volume has a preset mapping relationship with the dome-shaped conical volume;

[0059] The data fusion module calculates the current cargo volume of the ship loading and unloading at the berth every preset time according to the cargo volume of the ship loading and unloading at the berth and the speed of the ship loading and unloading at the berth, and loads the corresponding number of container models or the corresponding volume of bulk cargo models;

[0060] The data fusion module also loads a corresponding number of container models or a corresponding volume of bulk cargo models according to the cargo type and cargo quantity of the ships entering and leaving the port.

Compared with the traditional multi-screen monitoring large screen, it is necessary to search for the area to be understood in multiple port video information. The present embodiment has stronger targeted management of the local area of ​​the port, and there is no need to search for the port video information of the area to be understood on the multi-screen monitoring large screen, so the user experience is better.

[0064] In another embodiment, the port multi-source information fusion display device further includes:

[0065] A navigation module, which is used to select berths with the same cargo loading and unloading type from all port berths according to the tonnage level of incoming ships and the cargo type of the ships, and to query whether these berths are currently in use;

[0066] If there are multiple unused berths, the berth with the shortest distance between the berth and the position of the incoming ship is selected, and the position of the berth is sent to the data display module so that the data display module highlights it. At the same time, the optimal heading, optimal speed and optimal driving path of the incoming ship are calculated based on the position of the berth, the position of the incoming ship, the wind speed, wind direction, wave level, tide and tidal current information of the port, and the optimal heading, optimal speed and optimal driving path of the incoming ship are sent to the data display module so that the data display module displays it;

[0067] If there is no unused berth, the vessel that completes loading and unloading the fastest and the remaining loading and unloading time are calculated according to the loading and unloading cargo volume, loading and unloading start time, and loading and unloading speed of the ships docked at the berths of the same loading and unloading type, and the position of the berth where the ship that completes loading and unloading the fastest and the loading and unloading countdown are sent to the data display module so that the data display module highlights and displays them. At the same time, the optimal heading, optimal speed, and optimal driving path of the incoming ship are calculated according to the position of the berth where the ship that completes loading and unloading the fastest, the position of the incoming ship, the wind speed, wind direction, wave level, tide, and tidal current information of the port, so that the entry of the incoming ship is connected with the departure process of the ship that completes loading and unloading the fastest, and the optimal heading, optimal speed, and optimal driving path of the incoming ship are sent to the data display module so that the data display module displays them.

[0068] In the above embodiment, after the navigation module integrates multiple data calculations and analyses, it can provide the berth information of the ship entering the port, as well as the optimal course, optimal speed and optimal driving path of the ship entering the port, so that the driver of the ship entering the port no longer needs to explore the ship driving parameters by himself, which reduces the driving workload of the driver of the ship entering the port and improves the experience comfort of the ship entering the port. At the same time, based on the setting of the berth arrangement strategy, the port berth can be used reasonably, reducing the defects of berth vacancies and long waiting time for ships entering the port, and effectively improving the production efficiency of the port.
