Harbor basin channel navigation guarantee evaluation method, system and device and medium

Abstract

The invention provides a harbor basin channel navigation guarantee evaluation method and system, and a medium, and the method comprises the following steps: scanning an interface data source, and obtaining an interface data packet; classifying the data in the interface data packet, and constructing a temporary data warehouse according to a classification result; extracting data from the temporarydata warehouse, converting the extracted data to obtain target data, and constructing a target data warehouse according to the target data; constructing an influence factor evaluation model, and outputting a result of the influence factor evaluation model according to the target data warehouse to obtain an evaluation model data packet; the method solves the problems of data source dispersion and data acquisition difficulty; the navigation capability evaluation result is automatically analyzed through big data, the navigation efficiency can be greatly improved, the port navigation service sceneis assisted to have higher safety, the accuracy of navigation safety evaluation is still superior to that of a traditional working mode in the state that the performance is improved and the cost is reduced, and the method, system and device can be widely applied to the technical field of traffic information engineering and control.

Description

technical field [0001] The invention belongs to the technical field of traffic information engineering and control, in particular to a method, system, device and medium for assessing navigation security of a harbor basin channel. Background technique [0002] In the existing technology, the status quo of port navigation safety assessment mainly relies on AIS, terminal video surveillance, radar and other independent auxiliary facilities and equipment to carry out work. In addition, during the navigation process, the measured historical data is analyzed offline to determine whether the navigation is safe. It mainly depends on the results of man-made experience assessment, which lacks real-time, dynamic and comprehensive data support, lack of underwater topography and landforms, and natural The combined analysis of environmental factors and the influence of the weight of the ship's own attributes is used as a guide for navigation guarantee. In most cases, the judgment is still ...

[0002] In the existing technology, the status quo of port navigation safety assessment mainly relies on AIS, terminal video surveillance, radar and other independent auxiliary facilities and equipment to carry out work. In addition, during the navigation process, the measured historical data is analyzed offline to determine whether the navigation is safe. It mainly depends on the results of man-made experience assessment, which lacks real-time, dynamic and comprehensive data support, lack of underwater topography and landforms, and natural Environmental factors and the influence of the weight of the ship's own attributes are combined and analyzed as a guide for navigation guarantee. In most cases, the judgment is still based on the accumulation of historical experience, which leads to the impact of normal navigation due to subjective judgment errors
