Urban traffic waterlogging early warning system

Abstract

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.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an urban traffic waterlogging early warning system. Background technique [0002] When the rainfall is large, waterlogging is prone to occur in the city, causing some roads to be flooded. In road design, the intersections of roads are usually local low-lying areas, which are prone to water accumulation. When the water level is low, vehicles can wade. When it is high, the vehicle is easy to turn off when wading into the water and cause losses, and it is not suitable to install contact liquid level sensors on the road to measure the water level. Non-contact liquid level sensors such as ultrasonic liquid level sensors need to be installed perpendicular to the water surface, so it is also difficult To measure the water level in the middle of the road or to build an L pole, the ultrasonic liquid level sensor can be installed in the middle of the road, but the cost is very high. ...

Non-contact liquid level sensors such as ultrasonic liquid level sensors need to be installed perpendicular to the water surface, so it is also difficult To measure the water level in the middle of the road or to build L poles, etc. so that the ultrasonic liquid level sensor can be set in the middle of the road, but the cost is very high
