Temporary UAV (unmanned aerial vehicle) traffic light and intersection monitoring system and control method

Abstract

The invention discloses a temporary UAV (unmanned aerial vehicle) traffic light and intersection monitoring system and a control method. The system comprises a UAV, wherein a central control module, a traffic light module, cameras, a loudspeaker, a wireless communication module, a storage and a power supply unit are arranged on the UAV; the traffic light module, the cameras, the loudspeaker, the wireless communication module, the storage and the power supply unit are connected with the central control module; the power supply unit is used for supplying power to electronic elements in the system; the UAV is provided with four rotor arms, the four rotor arms constitute a cross shape, the traffic light module is suspended below the rotor arms, and each camera is arranged on the corresponding rotor arm. According to the system and the method, the UAV is taken as a carrier, height of traffic lights and the monitoring system can be adjusted flexibly and conveniently, and by rising the UAV, monitoring dead angles can be avoided and the condition that a vehicle driver cannot see the traffic lights due to blockage of a large vehicle can also be prevented. Besides, flow of vehicles which are to pass can be pre-judged, working time of the traffic lights in different states is calculated on the basis of the pre-judgment, the real-time calculation is realized, precision is high, and commanding effect is good.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a system for directing traffic based on unmanned aerial vehicles. Background technique [0002] In urban traffic management, traffic lights and monitoring equipment are essential electronic products. Existing intersection traffic lights and monitoring equipment are all fixed on light poles, and are powered by mains power. Once a power failure occurs, traffic paralysis and insufficient evidence for traffic accidents will occur. Moreover, because the height of the traffic lights at the intersection is fixed, when the vehicle passes the intersection, the driver's sight is easily blocked by tall vehicles traveling with him, which makes it impossible to see the changes of the traffic lights in time, and accidents that violate regulations are prone to occur. Similarly, since the height of the monitoring equipment is also fixed, its shooting angle is also e...

AI Technical Summary

Problems solved by technology

The existing intersection traffic lights and monitoring equipment are fixed on the light poles and powered by the mains. Once the power is cut off, there will be traffic paralysis and insufficient evidence for traffic accidents.

Moreover, due to the fixed height of the traffic lights at the intersection, when the vehicle passes the intersection, the driver's sight is easily blocked by tall vehicles traveling with him, resulting in the inability to see the changes of the traffic lights in time, which is prone to accidents

Similarly, since the height of the monitoring equipment is also fixed, its shooting angle is also easily blocked by tall vehicles, making it impossible to obtain sufficient evidence
