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.
本发明公开了一种用于通航船舶桥梁防撞的预警方法及装置,属于桥梁建设和桥墩保护技术领域;该方法在大桥区域两侧通航航道上按船舶与桥墩的距离设定预警区,紧急区,危险区;对桥梁水域一定距离范围内的过往船舶进行实时测距,检测船舶是否位于通航桥洞方向,如果船舶在非通航桥洞的方向上,发出预警信号;具体为:当船舶进入预警区时,发出一级预警警告,通过声光报警提醒船舶驶入正常航道;当船舶进入紧急区时,发出二级紧急警告,促使船舶驶出紧急区,同时通过人工干预引导船舶正常航行;当船舶驶入危险区时,发出三级危急警告,通知桥梁管理人员响应紧急措施,促使船舶进入安全通道。该预警方法及装置受外界影响小,成本低,维修简单。
