Anti-collision radar early warning system of railway bridge

Abstract

The invention discloses an anti-collision radar early warning system of a railway bridge. The system comprises a host computer, and an X wave band radar detection device, a wireless communication device, a sound-light alarming device and a recording device which are connected with the host computer. The X wave band radar detection device is installed on a bridge pier. Ships sailing in a preset region in front of the bridge pier are detected by use of X wave bands, and detected data is sent to the host computer in real time. The host computer determines region and time where the ships locating in according to the received data, and executes corresponding operation for the region, thereby achieving the anti-collision early warning and collision warning for the bridge pier.

Description

technical field [0001] The invention relates to the field of radar early warning. Background technique [0002] Due to certain restrictions in the design of railway bridges, there is basically no pier anti-collision system designed. However, due to the rapid development of inland river transportation, the piers of railway bridges are often collided by various ships, which has threatened the safety of the bridge, especially the safety of railway transportation. Due to the lack of corresponding early warning / alarm systems, it is impossible to grasp and effectively detect the collision of bridge piers in a timely manner. [0003] At present, there are the following solutions for remote monitoring and early warning systems, but all of them have deficiencies: [0004] 1) The laser rangefinder is used as the measurement sensor. It has been verified by experiments that the laser energy is easily scattered by water. The rangefinder with a range of 30m cannot receive the reflected ...

Problems solved by technology

[0006] 3) The use of ordinary Doppler radar as a detector is too limited by the installation conditions. First, the sensor must be installed 4 meters away from the bridge pier. The installation risk is high and the use is extremely inconvenient

The second is to cause false alarms on floating objects on the river surface

[0007] 4) Using the camera moving image alarm method, first, the alarm parameters set by the camera during the day do not match the image changes at night (color during the day, black and white image at night), resulting in a decrease in sensitivity

The second is that the foggy weather directly causes the sensitivity to drop, and the bridge collision rate at this time will be higher than usual, and it is easy to miss the report
