[0001] The present invention relates to the technical field of bridge safety, and in particular to a bridge anti-collision active early warning and monitoring system and method. Background Art

[0002] As inland waterway transport capacity increases, the risk of bridge-ship collisions increases. The primary purpose of bridge collision prevention monitoring is to monitor traffic conditions in the waterways or roads surrounding bridges in real time. Using methods such as laser beaming, lidar, AIS, microwave radar, visible light cameras, and thermal imaging, ships can be detected to promptly detect and warn of potential collisions, effectively avoiding collisions and ensuring the safety of bridge structures and smooth traffic.

If a potential collision risk is identified, it is marked and the early warning module issues an alert and provides guidance. At the same time, a towing vessel is activated and moves to the vicinity of the marked vessel. S3. Sound and light alarm equipment provides early warnings, reminding ships to make timely adjustments, controlling ships to slow down, avoid or return to the channel. If the situation is complex, the environment is harsh, and the ship's operators are restricted, wireless communication equipment will be used to contact the ship's drivers and management personnel for coordination and guide the ship through. S4. If the vessel fails to make timely adjustments, or if the loss of control is confirmed after contacting the crew, the towing vessel will contact the vessel in question and begin towing intervention, pushing or pulling, or directly colliding with it, changing the direction of the vessel to avoid a collision. S5. After the out-of-control vessel has stabilized and moored, or has returned to its normal course, the information processing module will cancel the mark, turn off the sound and light alarm equipment, and the towing vessel will return to the berth, restoring normal passage on the waterway.
