Method for bridge-culvert waterlogging monitoring and alarm according to vehicle model

Abstract

The present invention relates to the technical field of bridge-culvert waterlogging monitoring, and discloses a method for bridge-culvert waterlogging monitoring and alarm according to a vehicle model. The method employs a technology for instantly detecting water level depth under a bridge culvert according to floating of a floating ball on the water surface and the gravity of a metal rod, and comprises the steps that: when there is no water under the bridge culvert, the mass of a small floating ball is larger than the mass of the metal rod, the small floating ball is located at the lowermostend, the metal rod is located at the uppermost end, and a circuit is in a non-electrifying state; when a L1 green light and a L4 green light are on, the water level corresponds to a safety water depth, a small vehicle X and a large vehicle D can safely pass; when a L2 yellow light and a L4 green light are on, passing of the small vehicle X is dangerous, and the passing of the large vehicle D is safe; and when a L2 yellow light and a L5 yellow light are on, passing of the small vehicle X and the large vehicle D is dangerous. The method for bridge-culvert waterlogging monitoring and alarm according to a vehicle model can detect the waterlogging depth under the bridge culvert to allow passing drivers to conveniently understand the bridge-culvert waterlogging condition through light-on of thedisplayed green light, the yellow light and the red light, can determine whether a vehicle can be safely passes or not according to the vehicle model and can timely regulate the route so as to avoid personnel and property loss.

Description

technical field [0001] The invention relates to the technical field of water accumulation monitoring in bridge culverts, in particular to a method for monitoring water accumulation in bridge culverts and alarming according to vehicle types. Background technique [0002] Looking at the urban traffic situation in recent years, it is found that a large amount of water in the low-lying areas of urban overpasses or tunnels caused by heavy rainfall has occurred from time to time, which has brought great inconvenience and safety hazards to the travel of pedestrians and vehicles. It affects the traffic of ordinary cars and passenger cars, and causes heavy property losses and even life threats to car owners. At this stage, every city has not established a perfect automatic monitoring and early warning system for urban road water accumulation. At present, rulers are installed under bridges and culverts to measure water depth. This method does not have early warning. Drivers can only k...

[0002] Looking at the urban traffic situation in recent years, it is found that a large amount of water in the low-lying areas of urban overpasses or tunnels caused by heavy rainfall has occurred from time to time, which has brought great inconvenience and safety hazards to the travel of pedestrians and vehicles. Serious It affects the passage of ordinary cars and passenger cars, causing heavy property losses and even life threats to car owners

At this stage, every city has not yet established a complete automatic monitoring and early warning system for urban road water accumulation. Currently, rulers are installed under bridges and culverts to measure water depth. This method does not provide early warning. Drivers can only know the water depth when they go under the bridge and culvert. And because the wading depths of large vehicles and small vehicles are different, if the water depth is too deep, small vehicles cannot pass, but large vehicles can pass, and small vehicles will be blocked on the road, affecting the passage of large vehicles and seriously affecting traffic.
