Water traffic risk dynamic test method, medium and system

Abstract

The invention discloses a water traffic risk dynamic test method, medium and system, and the method comprises the steps of building an internal information set of a water traffic system through the export of ship equipment, the collection of a maritime department, and the consultation, investigation and extraction of information of a captain, wherein the information set comprises navigation environment information, man-machine interaction information and ship-shore communication information; extracting and measuring non-uniform characteristics of internal information transmission of a water traffic system in combination with an information flow theory, and realizing water traffic risk dynamic characteristic extraction and analysis modeling by utilizing wavelet transform and spectral analysis; using a data driving method to construct a water traffic risk dynamic test model; and finally, inputting the abnormal characteristic value of the water traffic system information of the test water area into the risk dynamic test model to obtain a risk calculation value of the water area. According to the invention, the dynamic test of the water traffic risk can be rapidly realized, and the efficiency and pertinence of water traffic safety supervision are improved.

Description

technical field [0001] The invention belongs to the technical field of water traffic risk assessment, and in particular relates to a dynamic test method, medium and system for water traffic risk. Background technique [0002] With the increasing traffic volume on the main line of the Yangtze River and the complex and changeable navigation environment, water transportation is facing unprecedented development opportunities and risks and challenges, which puts forward higher requirements for the level of maritime safety supervision. [0003] Traditional water traffic safety risk assessment methods such as Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE) can be better applied to the sea, but AHP and FCE are not suitable for water traffic safety risk identification in complex waters. There are large limitations in the application of AHP and FCE evaluation, so that in the process of maritime supervision, there are large deviations and lags in the early war...

AI Technical Summary

Problems solved by technology

[0007] (1) The traditional water traffic safety risk assessment methods mostly characterize the static risk of the human-ship-environment system, so that there are large deviations and lags in the early warning and pre-control of water traffic safety risks based on the evaluation results in the maritime supervision process, resulting in maritime supervision. The decision-making department cannot effectively identify the traffic safety risks in the supervised waters, which reduces the energy efficiency of the maritime supervision department in the early warning of traffic safety risks

[0008] (2) The existing traffic risk assessment methods rely on static historical data for risk assessment analysis and modeling, but there is no mature method for analytical modeling of the dynamic characteristics of water traffic risks, and the dynamic characteristics of water traffic risks are not yet clear. Traffic risk situation analysis and dynamic evaluation methods are lacking
