Bridge ship collision prevention intelligent early warning method and system based on multi-source data fusion

Abstract

The invention provides a bridge ship collision prevention intelligent early warning method based on multi-source data fusion. The method comprises the steps of obtaining the real-time data parameters of the environment of a bridge, wherein the real-time data parameters comprise a predicted navigation track received by an AIS data receiver of a monitoring center, acquiring a height measurement area which is determined according to the predicted navigation track and is predicted to pass by the ship, and acquiring a probability of generating a collision risk when the ship is predicted to pass by the bridge and calculated according to the predicted navigation track, when any one or all of the ultrahigh early-warning information and the high-risk early-warning information is confirmed to be received, confirming that early-warning operation is started, and triggering a video integration device, wherein the video integration device comprises a camera provided with a visible light sensor and an infrared sensor, acquiring live video parameters of the early warning operation, and storing the current operation information of the ship to a database when the live video parameter is confirmed to be safe driving away of the ship.

Description

technical field [0001] The invention belongs to the relevant technical field of ship avoidance, and specifically relates to an intelligent early warning method for ship collision prevention of bridges based on multi-source data fusion and an intelligent early warning system for ship collision prevention of bridges based on multi-source data fusion. Background technique [0002] With the rapid development of my country's infrastructure and shipping industry, the number of bridges and the navigation density of waterways have increased year by year, and the contradiction between bridges and navigation ships has become increasingly prominent. Accidents of ships colliding with bridges are not uncommon, and accidents of ship colliding with bridges usually lead to serious economic, social, personal and property losses, as well as environmental pollution problems. [0003] At present, most of the common anti-ship devices for bridges are passive, and the auxiliary structures of bridg...

Problems solved by technology

That is, the real-time monitoring of the camera, its disadvantages: the camera's night vision ability is poor, and the image at night is blurred, which is not conducive to ship identification; it is greatly affected by the weather, and the visibility is low in rainy and foggy days, which may easily cause false positives and false positives

[0007] (3) The laser rangefinder is used as a measurement sensor, the laser energy is easily scattered by water, and the reflected beam is easily lost

[0008] (4) Ordinary Doppler radar is used as a detector, and its installation conditions are too restrictive. First, the sensor must be installed at a certain distance away from the bridge pier. The installation risk is high and it is extremely inconvenient to use. Second, it is easy to detect floating objects on the river surface. report
