Bridge active anti-ship collision system and use method thereof

The invention discloses a bridge active anti-ship collision system and a use method thereof. The system comprises a target detection and alarm module, a data processing and analysis module and a monitoring and human-computer interaction module which are all arranged on a bridge; and a photoelectric composite detection and active early warning mode is adopted to judge the mistake of the driver of a ship and the abnormal navigation attitude of the ship. According to a video monitoring-based navigation bridge active anti-ship collision early warning concept and program, visible light, infrared and laser are adopted to perform composite detection; detected data are fused; and therefore, collision accidents caused by factors such as human factors and ship out-of-control factors can be decreased to the greatest extent, early warning can be performed, and related departments can be notified to close the traffic of the road of the bridge, and secondary life and property loss caused by the ship-bridge collision accide
