The invention discloses an urban traffic waterlogging early warning system. The system comprises a BIM modeling system used for determining the low-lying position of each road section, a non-contact water level sensor installed on the side face of the low-lying position of each road section and a wireless receiver installed on a vehicle. The non-contact water level sensor is in wireless connectionwith an upper computer, and the upper computer is in wireless connection with the wireless receiver; and the non-contact water level sensor comprises an installation base, and a through hole is formed in the installation base. A light emitter and at least two cameras are mounted on the installation base; and the path of the light emitted by the light emitter passes through the lowest-lying part of the road section. Non-contact detection on the depth of accumulated water on the road surface in an inclined mode is achieved, the installation cost of the water level sensor is reduced, corresponding warning is conducted on the accumulated water on the road surface by a driver, anchoring caused by wading of a vehicle in a city is effectively reduced; meanwhile, the water accumulation speed is predicted, and disaster relief in time is facilitated.
本发明公开了一种城市交通内涝预警系统,包括用于确定各路段低洼处的BIM建模系统、在各路段低洼处的侧面安装的非接触水位传感器和安装在车辆上的无线接收器,非接触水位传感器无线连接有上位机,上位机无线连接无线接收器;所述非接触水位传感器包括安装座,安装座上成形有通孔;安装座上安装有一个光线发射器和至少两个摄像头;光线发射器发出的光线路径经过所处路段的最低洼处。本发明实现了倾斜式对路面积水深度进行非接触检测,降低了水位传感器的安装成本,并对司机对路面积水进行对应示警,有效降低了车辆在城市内涉水导致的抛锚,同时是对积水速度进行预测,便于及时救灾。
