Bridge anticollision early warning rotary table

Abstract

The invention discloses a bridge anticollision early warning rotary table comprising a rotatable support component and a control component as well as an intelligent detector and an intelligent alarm device which are arranged on the support component, wherein the intelligent detector comprises a shape detecting component used for acquiring vessel shape data and a position detecting component used for acquiring vessel position data. The bridge anticollision early warning rotary table disclosed by the invention has the beneficial effects of good integrity, high automation degree, low cost and the like.

Description

technical field [0001] The invention relates to the field of early warning technology, in particular to a bridge anti-collision early warning turntable. Background technique [0002] In order to prevent objects, such as ships, from colliding with bridges, causing property damage and hindering waterway traffic, it is necessary to set up an early warning system to give early warning to the impact of objects. [0003] The Vessel Traffic Management System (VTS system) can effectively locate and track multiple targets in the water surface area of ​​several kilometers to hundreds of kilometers. Therefore, we can learn from the experience of VTS and deploy radar equipment on the bridge foundation to monitor the navigation behavior of ships in the bridge site area. The VTS system pre-judges the risk of collision and sends an early warning to ships that may hit the bridge, thereby reducing the risk of ships hitting the bridge. However, the current VTS system has the following disad...

AI Technical Summary

Problems solved by technology

[0004] (1) The radar in the VTS system is microwave radar equipment, which is expensive;

[0005] (2) The time for the radar to establish tracking is too long, up to one antenna scanning cycle, which is not suitable for quickly establishing a steady state tracking of maneuvering targets in the port area;

[0006] (3) The radar is suitable for tracking in a wide range of water surface areas, but for targets in densely trafficked port waters, the phenomenon of tracking and tracking is more serious, and the resolution of detection and tracking between two ships is low;

[0007] (4) The radar equipment cannot detect the shape and size data of the ship, so it is impossible to determine whether the ship will hit the basic data of the ship shape required by the bridge, and it is impossible to accurately give an early warning;

Therefore, using the VTS system to detect bridges, the detection effect is not ideal, but the cost is extremely high
