Some domestic platforms that integrate positioning and monitoring services only monitor engineering vehicles, etc., and do not take into account the safety management and safety monitoring of operating personnel and materials, and lack overall safety management awareness."

[0005] However, at present, after leaving the port, the seaborne cargo ship is facing many uncertain factors due to the rapidly changing weather conditions at sea, which threatens the safety of the seaborne cargo ship and the crew on board.

[0006] To this end, we proposed a comprehensive management system for seaports and oceans based on blockchain technology. Summary of the invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides a seaport and ocean integrated management system based on blockchain technology, which solves the technical problems raised in the above-mentioned background technology.

[0011] Among them, when the interactive module feeds back the decision results to the corresponding ship, the interactive operation is performed through the wireless network. The monitoring terminal is integrated with a computer device with display function. During the operation stage of the monitoring terminal, the ship's navigation area is displayed in real time, and the real-time position information of the returning ships in the ship's navigation area is continuously updated and displayed.

[0012] Furthermore, the upload module is provided with submodules at the lower level, including:

[0013] Sensing unit, used to sense the position information of outbound ships in real time;

[0014] The storage unit is used to receive the sailing route of the outbound ship uploaded by the uploading module and the real-time position information of the outbound ship obtained;

[0015] Among them, the sensing unit is integrated by several groups of position sensors, and each of the ships is equipped with no less than one group of position sensors. The position information of the outbound ship is sensed in real time based on the position sensors and fed back to the upload module. The sailing route of the outbound ship and the real-time position information of the outbound ship are both configured with marking information, and the content of the marking information is the name of the outbound ship. When the storage unit stores the sailing route of the outbound ship and the real-time position information of the outbound ship, it distinguishes and stores them based on the marking information.

[0016] Furthermore, each group of the position sensors is provided with an operation cycle, and each group of the position sensors continuously operates based on the respective set operation cycles to sense the position information of the outbound ship;

[0017] The setting logic of the operating cycle of the position sensor is expressed as:

[0018] ;

[0019] Where: , is the next operation cycle of the position sensor; It is the initial setting value of the operation cycle of the position sensor; is the risk value of the area where the position sensor corresponds to the ship; Indicates taking the minimum value in brackets;

[0020] In the above formula, based on formula (1), After that, we further determine in formula (2) Is it greater than or equal to ,exist Greater than or equal to When , take the formula (2) As the next operating cycle of the position sensor, on the contrary, take the formula (1) As the next operating cycle of the position sensor.

[0021] Furthermore, the acquisition module is integrated with a wind level and direction sensor, a radar wave height meter, a current meter and a temperature and humidity sensor, and the meteorological data of the ship's navigation area collected by the acquisition module include: wind level, wind direction, wave height, wave period, seawater flow velocity, seawater flow direction, temperature and humidity;

[0024] The acquisition module synchronously stores the collected meteorological data of the ship navigation area, and the number of meteorological data of the ship navigation area stored in the acquisition module is set to no more than twenty-four groups. When the stored meteorological data of the ship navigation area exceeds twenty-four groups, the acquisition module deletes the earliest meteorological data of the ship navigation area stored internally.

[0025] Furthermore, the evaluation logic of the risk value of the area where the ship is located in the evaluation module is expressed as:

[0026] ;

[0027] Where: is the risk value of the area where the ship is located; The wind level of the latest meteorological data collected for the ship's navigation area; The angle between the wind direction and the ship's hull in the latest meteorological data collected in the ship's navigation area; The wave period of the latest collected meteorological data in the ship's navigation area; It is the maximum value of the wave height in the meteorological data of the ship's navigation area; It is the maximum value of seawater velocity in the meteorological data of the ship's navigation area; The total amount of meteorological data in the ship's navigation area; is the deviation of the seawater flow direction in the meteorological data of the i-th group of ship navigation area and the seawater flow direction in the meteorological data of the i+1-th group of ship navigation area; is the humidity value in the meteorological data of the navigation area of ​​the i-th group of ships; is the temperature value in the meteorological data of the navigation area of ​​the i-th group of ships;

[0030] Furthermore, when the analysis module runs to analyze the risk values ​​of the adjacent areas of the area where the ship is located, the analysis logic applied is the same as the logic for calculating the risk value of the area where the ship is located, and the analysis target of the risk values ​​of the adjacent areas of the area where the ship is located is: the risk values ​​of the adjacent areas of the area where the ship is located at the same time as the risk value of the area where the ship is located is calculated.

[0031] Furthermore, the analysis module is internally provided with submodules, including:

[0032] Decision-making unit, used to decide whether the ship should return;

[0033] Among them, the risk values ​​of the adjacent areas where the ship is located are further summed and averaged after being obtained. When the average result is greater than the risk value of the area where the ship is located, the ship is decided to return. When the average result is less than the risk value of the area where the ship is located, the ship is decided to continue sailing.

[0037] The safe navigation area recommended by the recommendation unit is transmitted to the corresponding ship by the interaction module in the form of corresponding coordinates of the grid area.

[0038] Furthermore, the upload module is interactively connected to a sensing unit and a storage unit at its lower level via a wireless network, the upload module is interactively connected to a collection module, an evaluation module and an analysis module via a wireless network, the analysis module is interactively connected to a decision-making unit via a wireless network, the decision-making unit is interactively connected to a recommendation unit at its lower level via a wireless network, and the analysis module is interactively connected to an interaction module and a monitoring terminal via a wireless network.
