Early warning method and device for collision avoidance of navigable ship bridge

Abstract

The invention discloses an early warning method and device for navigation ship bridge collision prevention, and belongs to the technical field of bridge construction and pier protection. According to the method, an early warning area, an emergency area and a danger area are set on navigation channels on the two sides of a bridge area according to the distance between a ship and a pier; real-time distance measurement is carried out on passing ships within a certain distance range of a bridge water area, whether the ships are located in the navigation bridge opening direction or not is detected, and if the ships are located in the non-navigation bridge opening direction, an early warning signal is sent out; when a ship enters an early warning area, a first-level early warning is given out, and the ship is reminded to drive into a normal navigation channel through sound-light alarm; when the ship enters the emergency area, a second-level emergency warning is given out to promote the ship to sail out of the emergency area, and meanwhile the ship is guided to sail normally through manual intervention; and when the ship drives into the danger area, a third-level emergency warning is sent out, bridge management personnel are notified to respond to emergency measures, and the ship is promoted to enter the safety channel. The early warning method and device are less affected by the outside, low in cost and simple to maintain.

Description

technical field [0001] The invention relates to the technical field of bridge pier protection, in particular to an early warning method and device for bridge collision avoidance of navigable ships. Background technique [0002] With the continuous development of transportation, the traffic volume of ships, automobiles and trains has increased, so the number of bridge collapse incidents induced by ship collisions is increasing day by day. Such events often lead to the loss of bridge structure, service life, safety and earthquake resistance, and even cause catastrophic consequences such as bridge destruction and death. Therefore, it is of great significance to carry out research on ship-bridge collision and pier anti-collision facilities, and to improve the crashworthiness of bridges. [0003] At present, the most commonly used bridge collision avoidance warning system is mostly visual remote monitoring and warning. A front camera is installed above the bridge, connected to t...

Problems solved by technology

The existing technology cannot accurately measure the distance from the ship to the pier, and there are serious errors; it is easy to be interfered, and is greatly affected by the surrounding light; the amount of data is large, the processing is complicated, and a large amount of resources of the MCU is required; when there is heavy fog, heavy rain, and heavy snow In bad weather, the observation range of the video camera is affected, which brings difficulties to the detection. In addition, the requirements for the responsibility and quality of the personnel are relatively high

The camera system requires regular maintenance and overhaul, which consumes a lot of manpower
