Embodiment 1

[0044] A method for early warning of ship traffic risk in port waters of the present invention comprises the following steps:

[0045] Step S1, start the system, detect the working status of the ship traffic risk warning in port waters in real time, and enter step S2;

[0046] Step S2. Determine the working status of the vessel traffic risk warning in port waters. If the vessel traffic risk warning in port waters is abnormal, proceed to step S9; if the port waters vessel traffic risk warning works normally, proceed to step S3;

[0047] Step S3, risk cause analysis information and risk early warning mechanism information;

[0048] Step S4, performing information fusion processing on the collected risk cause analysis information and risk early warning mechanism information;

[0049] Step S5, according to the ship collision risk measurement model, combined with the risk cause analysis information and the risk early warning mechanism information, conduct a real-time traffic risk ...

Abstract

The invention discloses a port water area ship traffic risk early warning method. The method comprises the following steps: S1, starting a system, and detecting a working state of port water area shiptraffic risk early warning in real time; S2, judging a port water area ship traffic risk early warning working state; S3, carrying out risk cause analysis information and risk early warning mechanisminformation; S4, performing information fusion processing on the acquired risk cause analysis information and risk early warning mechanism information; S5, according to a ship collision risk measurement model, combining the risk cause analysis information and the risk early warning mechanism information; S6, constructing an early warning index system; S7, generating a rough set reduction index according to different risk values; S8, constructing an SVM training model by using a modeling software SVM algorithm; S9, carrying out precision inspection; and S10, giving an early warning result.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a method for early warning of ship traffic risks in port waters. Background technique [0002] The research on ship traffic risk warning in port waters has always been an important research direction in the field of intelligent navigation. On the basis of the existing research on vessel traffic risk analysis and assessment, from the perspective of early warning, combined with early warning models and methods in other fields, a new exploration and research on vessel traffic risk in port waters is carried out. The results show that early warning research on vessel traffic risk in port waters is feasible and necessary, which not only broadens the direction of related research on vessel traffic risk, but also provides theoretical support for the maritime department to more effectively supervise the dynamics of vessel traffic risk. [0003] Early warning of vessel traffic risks in...
