[0001] The present invention relates to the technical field of shipping management, and in particular to a comprehensive analysis method for shipping navigation based on a trusted data space. Background Art

[0002] Shipping refers to the transportation of people or goods through waterway transportation, air transportation, etc. Generally, waterway transportation takes a longer time but has a lower cost, which cannot be compared with air transportation and land transportation. Each voyage of waterway transportation can carry a large amount of goods, while the load quantity of air transportation and land transportation each time is relatively small. Therefore, in international trade, waterway transportation is a more common transportation method.

[0003] With the continuous change of the demand for waterway transportation, along with the change of the hydrological environment in different seasons, it is necessary to make timely adjustments to meet the shipping navigation requirements. However, the navigable area is vast and the navigation environment is complex and diverse. The data collected and analyzed is huge and complex. Analyzing by humans is time-consuming and laborious and cannot be adjusted in time according to the change of the navigation status. Therefore, it is necessary to design a comprehensive analysis method for shipping navigation based on a trusted data space, which can perform intelligent analysis according to the obtained shipping data and environmental data, adjust according to the demand and environmental changes, comprehensively analyze whether the current shipping navigation needs to be adjusted, provide shipping suggestions to the management side, and ensure navigation safety and optimize the shipping environment.
