The invention discloses a method for judging whether a ship can pass through a bridge opening or not based on an electronic fence. A digital access control system and a navigation system are included. And the digital access control system is used for respectively establishing a hole edge positioning electronic fence L1, a hole protection positioning electronic fence L2 and a ship profile prediction positioning electronic fence L3 on the virtual reference plane, comparing the L3 with module values of the L1 and the L2, permitting passage when a comparison result meets a condition, and otherwise, forbidding passage. According to the navigation system, navigation marks are arranged in a water area in front of the bridge opening, laser navigation lamps are arranged above the bridge opening, and the ship is guided to reduce course deviation and always pass through the bridge opening along the central axis of the bridge opening. The method is suitable for solving the problems that an existing ship passing through a bridge opening needs to be guided by professional pilots on the ship, and navigation is not safe, rapid and economical.

    本发明公开了一种基于电子围栏的判定船舶能否通过桥孔的方法,包括数字门禁系统和导航系统。数字门禁系统:通过在虚拟基准平面分别建立孔沿定位电子围栏L1、孔保定位电子围栏L2、船廓预测定位电子围栏L3,并将L3与L1、L2的模值进行比对,比对结果符合条件时许可通行,否则禁止通行。导航系统:通过在桥孔前方水域设导航航标,在桥孔上方设激光导航灯,引导船舶减小航向偏差、始终沿桥孔中轴线通过桥孔。本发明适用于解决现有穿行桥孔船舶需专业引航人员上船引导,通航“安全、快捷、经济”性不高的问题。
