The invention provides an inland river bridge grading early warning system, and relates to the field of inland river bridge grading early warning systems, the inland river bridge grading early warning system is arranged on an upstream river section in front of a bridge, and the grading early warning system comprises a height limiting early warning area, a slow moving early warning area, an impact early warning area and a bridge outline marker area which are sequentially distributed in the length direction of the upstream river section. Four levels of early warning areas including a height limit early warning area, a slow-moving early warning area, an impact early warning area and a bridge outline marker area are divided in the ship coming direction of the bridge, the height limit early warning area reminds the current water level, the ship height, the bridge height limit and other data, whether the ship can pass through the bridge or not is recognized in advance, and if not, the ship stops moving forwards in time; the slow-moving early-warning area is mainly used for reminding the position of a bridge which is about to arrive in front, reminding information such as bridge height, width between piers, current water flow speed and wind speed and reminding ships to slow moving; in the collision early warning area and the area where the road approaches the bridge, the radar monitors the positions of the ship and the bridge pier, the ship distance is fed back in real time, and an alarm is given out when the risk distance is reached.

    本发明提供一种内河桥梁分级预警系统,涉及内河桥梁分级预警系统领域,设置在桥梁前的上游河流段上,所述分级预警系统包括沿着上游河流段长度方向依次分布的限高预警区、缓行预警区、撞击预警区、桥梁示廓区。在距离桥梁来船方向,划分限高预警区、缓行预警区、撞击预警区、桥梁示廓区等四个级别的预警区域,限高预警区提醒当前水位、船高、桥梁限高等数据,提前识别船舶是否可通过桥梁,如果不能及时停止前进;缓行预警区主要提醒前方即将到达桥梁位置,提示桥梁高度、桥墩间宽度,当前水流速度、风速等信息,提醒船舶缓行;撞击预警区,道道接近桥梁的区域,则通过雷达监测船舶与桥墩位置,实时反馈船舶距离,达到风险距离发出报警。
