Aiming at the safety of ships passing through bridge , based on the self-developed long distance lidar LS30M, a bridge collision avoidance solution was proposed.
The core of this solution is long range LiDAR scanner, which is installed on both sides of the bridge pillars. As shown in Figure in the left, the installation height of the LiDAR is the height limit of the bridge. The two LiDARs cross to detect the ship. When the ship is higher than the height limit of the bridge, at least one of LiDARs will detect the ship and the system will output an alarm signal. And it can know the position and distance of the vessel, and issue warning in time and can send a warning to ultra-height vessel through the tweeter and large LED screen. At the same time, the early warning information is displayed in the monitoring hall. After receiving the early warning, the maritime law enforcement department and bridge maintenance personnel will deal with the danger in a timely manner, effectively avoiding the collision of the vessel with the bridge due to the over height.
