Problems solved by technology
However, due to the high speed of expressway vehicles, when placing warning signs, it is often easy to slow down because the vehicles behind are too late; or the owner does not park the car in the emergency lane in time to get off and place warning signs, causing serious casualties
[0003] The existing warning signs mounted on UAVs can solve this problem to a certain extent, but there are still the following shortcomings: 1. UAVs cannot make corresponding responses according to the driving conditions of vehicles on the road; 2. UAVs Fixed together with the warning sign, it needs to be separated artificially, the volume is large, it is not conducive to storage, and it can only remind the rear vehicles at a lower position, which is not conducive to the observation of distant and large vehicles; 3. Simple hanging of drones and warning signs Together, it takes a lot of time to adjust the position of the warning sign when using it

The invention discloses a system and method for placing a traffic accident warning sign based on an unmanned aerial vehicle. The driving speed is used to obtain the judgment result of the driving condition of the vehicle; the communication module is used to transmit the driving speed and the judgment result of the driving condition of the vehicle; The drone performs vehicle positioning, double flashing light detection and accident warning for faulty vehicles. The present invention can not only implement different tasks according to different traffic conditions, but also does not need manual assistance, and is convenient for the observation of large vehicles behind. In the actual application process, it does not need to spend a lot of time to adjust the position of the warning sign, which greatly improves work safety and work safety. Efficiency liberates manpower.
Description
technical field [0001] The invention relates to the field of UAV traffic, in particular to a system and method for placing a traffic accident warning sign based on an UAV. Background technique [0002] At present, when an accident occurs on the highway, the car owner usually turns on the double flashing lights, parks the car in the emergency lane in time, and then artificially places a warning triangle about 150 meters behind the car, and the car owner from behind sees the warning in the distance The card will react in advance. However, because the speed of the expressway vehicle is too fast, it is often easy for the rear vehicle to slow down when the warning sign is placed; [0003] The existing warning signs mounted on UAVs can solve this problem to a certain extent, but there are still the following shortcomings: 1. UAVs cannot respond accordingly according to the driving conditions of vehicles on the road; 2. UAVs It is fixed with the warning sign and needs to be separ...
