The invention discloses a ship ultrahigh collision bridge early warning method based on a differential GNSS technology, and the method comprises the following steps: S1) carrying out the static and accurate measurement of the elevation of a bridge based on a differential GNSS, and obtaining the elevation of each bridge; s2) carrying out dynamic and accurate elevation measurement on the ship based on a differential GNSS (Global Navigation Satellite System); and S3) comparing the elevation of the ship at the moment with the previously measured elevation of the bridge when the ship is navigated to the water area of the bridge area, and judging whether the ship can safely pass through the bridge or not. According to the early warning method for the ultrahigh collision of the ship with the bridge based on the differential GNSS technology, the elevation of the bridge opening and the ship can be accurately calculated, the measurement precision is improved, the early warning requirement of the ultrahigh collision of the ship with the bridge is well met, and the safety of ship navigation is greatly improved.

    本发明公开了一种基于差分GNSS技术的船舶超高碰撞桥梁预警方法,包括如下步骤:S1)基于差分GNSS对桥梁进行高程静态精确测量,获得每座桥梁的高程;S2)基于差分GNSS对船舶进行高程动态精确测量;S3)在通航至桥区水域时将此时船舶高程与之前已测量的该桥梁的高程进行对比,判断船舶能否安全通过桥梁。本发明提供的基于差分GNSS技术的船舶超高碰撞桥梁预警方法,能够精确计算桥孔和船舶的高程,提高测量精度,较好地满足了船舶超高碰撞桥梁的预警要求,大大提高了船舶通航的安全性。
