In recent years, the global demand for cargo transportation has grown rapidly. Especially with the development of hub ports and shipping technology, bulk commodity transport ships have gradually become larger, bringing economies of scale and far-reaching impacts on port enterprises and shipping companies. The large-scale ships have led to a significant improvement in the berthing capacity, channel depth, loading and unloading equipment and other facilities, equipment and technical capabilities of countries around the world, especially bringing higher requirements for ship berthing and port safety. Due to their large load and size, large dry bulk ships are greatly affected by natural conditions, traffic environment, port environment and day and night differences during navigation and berthing and unberthing operations. Especially at night, in severe weather conditions such as fog and snow, visibility is poor, resulting in limited vision for operators and greater safety risks. All major ports have not achieved normalized berthing and unberthing operations at night, lack of effective monitoring and safety risk assessment of large ships' navigation safety at night, and few research results on information construction in related fields.

[0017] In the embodiment: ① The laser berthing monitoring module includes a laser rangefinder 1, a large display screen 2 and a mobile terminal. The number of the laser monitors 1 is 6, and 6 laser rangefinders 1 are used on site to monitor the ships at berths 5# and berths 6#; the laser rangefinder 1 is installed in an automatic lifting guide rail, and the laser sensor of the laser rangefinder 1 is in the highest position of the protection warehouse by default, and the protection warehouse is 1 meter higher than the dock platform surface, so as to facilitate later maintenance. When the centralized control center or on-site operation starts the system, the laser sensor automatically runs from the protection warehouse to the set distance from the water surface for ship monitoring (the default distance from the water surface is 2m, which can be modified and adjusted according to actual conditions), and the laser sensor automatically adjusts the distance from the water surface according to the water level. The system automatically recognizes that the ship is leaving the berth and turns off, and the laser sensor automatically returns to the protection warehouse. At the same time, considering the dock extension project to meet the needs of ship laser monitoring, it is planned to deploy 2 laser monitoring points in the expansion area on the side of the dock, and request equipment addition after the project is completed.
[0018] The large display screen 2 is used to display the real-time monitoring parameters of the ship (berthing distance, berthing speed and angle of the bow and stern of the ship). There are three large display screens in total, located at the east platform of berth 6#, the junction of berths 5# and 6#, and the west side of berth 5#. The large display screen 2 on the east platform of berth 6# is fixedly installed, with a base height of 6 meters and an angle of 45° with the dock surface; the large display screen 2 at the junction of berths 5# and 6# is equipped with an automatic rotation function, with a self-locking device, a base height of 3 meters, and is parallel to the dock surface when not in operation. It can be rotated 30° to the east or west according to the berthing situation (the rotation angle is adjustable); the large display screen 2 on the east platform of 5# is fixedly installed, with a base height of 3 meters and an angle of 30° with the dock surface.
[0019] The mobile terminal can perform real-time and effective data access through mobile terminal applet, browser, and APP.
[0020] ② Environmental monitoring module. According to the differences in the ocean current environment between berth #5 and berth #6, the environmental monitoring module deploys single-layer velocity sensors and Doppler current sensors respectively to monitor the ocean current environment (velocity, flow direction, temperature, wave value, tide) of the two berths in real time. The single-layer velocity sensor is installed on the west platform of berth #5, and the Doppler current sensor is installed on the east platform of berth #6. Both are installed in a crane-type manner and can be powered by cables, battery packs and photovoltaic panels.
[0021] ③ Cable stress monitoring module, research and develop the communication system of the original 8 electric cable hooks at the terminal, integrate the Internet of Things and UHF communication interface, transmit the data of the electric cable hook control box back to the terminal control room, and display and store data on other terminals.
[0022] ④ Channel navigation risk assessment module: Based on the actual situation, the project systematically analyzes the key navigation environment elements of the waters, identifies the navigation risks of large ore ships berthing and leaving at night, conducts simulation tests on night ship operation, proposes navigation safety assurance measures in emergency situations at night, and then develops a night ship navigation safety assurance system. The system can provide pilots, dispatchers and other relevant operating personnel with real-time navigation data such as wind, waves, currents, and visibility in the waters of the route. Based on a high-precision hydrodynamic model, it conducts a line assessment of night navigation safety, and predicts and forecasts the operation window period for ships to enter the port during the tide.
[0023] The centralized control center is equipped with system software to realize laser monitoring, environmental monitoring, cable stress monitoring, real-time data collection, storage and query while the ship is in port and berthing. It also processes the data information and provides relevant early warning functions.
[0024] Refer to the attached Figure 2, the specific process of the implementation example: after the ship arrives at the berth; the first step: set the propagation information, set the mooring mode, and display the propagation information interface; the second step: start monitoring, enter the monitoring interface, and then automatically jump to the berthing or unberthing interface, and then jump to the drift monitoring interface; the third step; stop monitoring and enter the stop monitoring interface.
