Problems solved by technology

However, these measures will be affected by climate, day and night, and some measures (AIS and VTS) may not be able to avoid the occurrence of ship collision accidents when the ship operator is in a state of drowsiness, dizziness, drunkenness, etc.
In addition, the VTS system makes the ship operator lose the degree of freedom, and the attribution of responsibility in the event of an accident is a very troublesome issue

Embodiment 1

[0060] Bridge anti-ship collision warning system based on far-infrared cross-thermal imaging, including central control computer, far-infrared camera and warning system installed on the bridge, such as figure 1 shown; as figure 2 As shown, there are two far-infrared cameras, which monitor the waters on one side of the bridge and are connected to the central control computer, which controls the warning system.

[0061] The far-infrared camera takes pictures of far-infrared thermal images of the water surface at fixed time intervals, such as 1 second. These pictures are sent to the central control computer in the monitoring room for comprehensive processing, and the ship targets on the water surface are automatically identified, and parameters such as the size, coordinate position, speed and course of the ship are calculated. The geographical and water plan of the bridge area is pre-stored in the central control computer, and the management personnel can set parameters such as...

[0064] The far-infrared camera takes pictures of far-infrared thermal images of the water surface at fixed time intervals, such as 1 second. These pictures are sent to the central control computer in the monitoring room for comprehensive processing, and the ship targets on the water surface are automatically identified, and parameters such as the size, coordinate position, speed and course of the ship are calculated according to the following method.

[0065] The coordinate positioning of the target ship on the sea surface in the bridge area can be carried out by usin...

Embodiment 3

[0101] Bridge anti-ship collision warning system based on far-infrared cross-thermal imaging, including central control computer, far-infrared camera and warning system installed on the bridge, such as figure 1 shown; as figure 2 As shown, there are three far-infrared cameras, which monitor the waters on one side of the bridge and are connected to the central control computer, which controls the warning system.

[0102] The farthest and closest distances between the water area to be monitored and the bridge are S max and S min , the height of the camera erection position from the water surface is H, the field of view angle in the vertical direction of the camera is 2β, and the installation pitch angle is α, then α and β should satisfy the following relations respectively:

[0103] β = 1 2 arccos H 2 + S ...

Abstract

The invention discloses an early warning system for protecting a bridge from ship collision based on far-infrared cross thermal imaging and belongs to the technical field of anti-collision early warning of the bridge. The system comprises a central control computer, and at least two far-infrared cameras and a warning system which are arranged on the bridge, wherein the far-infrared cameras are used for monitoring a water area on one side of the bridge and connected with the central control computer; and the central control computer controls the warning system. By adopting a far-infrared thermal imaging technology, the system can normally operate at night and in heavy weather such as a foggy day and rain and snow days; and when the ship deviates and then enters a prohibited area, the system can timely give an alarm to a ship operator and a bridge manager by using signals such as a strong sound and a bright light, and the ship operator and the bridge manager can take measures as soon as possible to avoid a ship collision accident. The system can be widely applied to anti-collision early warning technical measures of all kinds of bridges.

Description

technical field [0001] The invention relates to an early warning system, in particular to a bridge anti-collision early warning system. Background technique [0002] With the increase of river and sea shipping volume and the increase of ship tonnage and speed, as well as the construction of a large number of river and sea bridges, the probability of ships colliding with bridges is increasing. Once the ship bridge collides, it will cause major accidents such as ship destruction and bridge collapse in severe cases, and huge economic losses; and it may also cause catastrophic environmental pollution due to damage and leakage of the ship hull. In recent years, there have been many such accidents in our country alone. The investigation and analysis of the accidents of ships colliding with bridges shows that most of the accidents are caused by the mistakes or carelessness of ship operators, such as drowsiness, dizziness, drunkenness, watching TV, chatting, as well as misoperation...
