Concave downward overpass water accumulating monitoring and traffic dispersion system

Abstract

The invention discloses a concave downward overpass water accumulating monitoring and traffic dispersion system, comprising a water depth sensor, a micro controller, a character library card, an LED (light-emitting diode) display screen, a wireless transmission module, a wireless receiving module, a motor and a traffic catch lever, wherein the water depth sensor is directly connected with the micro controller, and is used for transmitting an acquired water depth voltage signal to the micro controller, after the signal is processed by the micro controller, water depth is displayed on the LED display screen, and a road forbidding state or a road permitting state is reflected by a traffic signal light. When the water depth exceeds a dangerous depth, the micro controller controls the traffic signal light to display the forbidding state, and simultaneously controls the wireless transmission module to transmit a starting signal, and after the wireless receiving module receives the signal, the motor is started to rotate, so that the traffic catch lever positioned in a central isolating zone of the road is uplifted, and vehicles are allowed to turn around for dispersing. The concave downward overpass water accumulating monitoring and traffic dispersion system is suitable for being mounted on a concave downward overpass for use, and after the system is mounted, not only can passing of vehicles be dispersed, but also occurrence of safety accidents of the vehicles and personnel can be prevented.

Description

technical field [0001] The invention relates to the field of sensor technology, computer technology, micro-controller automation, especially the field of automation control. Background technique [0002] On July 21, 2012, the torrential rain in Beijing caused the overpass flooding event, which has become one of the hot spots in the society in recent years. The accumulated water under the sunken overpass became an obstacle for many vehicles to pass. The vehicles were blocked and difficult to move, and finally they were submerged in water, resulting in heavy losses of personnel and property. At present, the meteorological department is still unable to accurately predict the local rainfall, and the area under the sunken overpass is a high-incidence area for accidents. If the depth of water accumulation under the bridge cannot be accurately measured, it will easily lead to accidents. The driver not only hopes to know the depth of the accumulated water in real time, but also hop...
