With the increasing maturity of the automotive industry, the automobile holding capacity is increasing year by year. While bringing convenience to daily trips of people, the wide application of automobiles also brings a series of safety problems, for example, the proportion of driving accidents is increased year by year. When a driving accident or any scene needing emergency stop occurs, a driver should place a triangular warning board right behind the vehicle or on the same lane so as to warn the vehicle behind. However, at present, because the vehicle density of the road is improved year by year, when an accident occurs, usually in the process that the vehicle just stops opening the double flashing, and a driver goes to the rear to place a triangular warning board, the rear vehicle is already close to the accident vehicle, especially, under the conditions that the high-speed vehicle-entering speed is too fast or the sight line in rain and fog weather is relatively poor, the rear driver often does not react and is already located at a position close to the accident vehicle, or the rear is a vehicle with a higher height, the vehicle at the next rear is closer to the rear vehicle, and after the rear vehicle with the higher height is emergently avoided, the next rear vehicle has the condition that the vehicle is not in time to react, especially, the risk is higher when the vehicle speed is higher, so that the probability of the occurrence of the secondary accident is easily increased.
When the emergency vehicle is parked in an emergency, a timely and safe warning device is arranged, so that the emergency vehicle has an important protection function for reducing secondary damage and saving lives. In the existing scheme, when an accident occurs, an accident driver needs to actively turn on the double-flashing lamps, then gets off and moves to the rear of a vehicle to place a warning board, the sight of the driver is blocked due to weather reasons, or the driver does not react timely at high speed, so that certain potential safety hazards exist. The driver has many operating conditions not according to the standard when placing warning device, if place the distance far away not enough, place the position and deviate from the dead astern, even have driver's vehicle and do not prepare warning device, bring the potential safety hazard equally. When natural environment or weather condition are serious calamity weather, get off to place warning device and can bring very big potential safety hazard equally like during typhoon, torrential rain weather, the warning device who places simultaneously exists to be blown down by the typhoon, blows away, blows off the position condition, and the potential safety hazard increases far away. Or some drivers are not required to place warning boards behind the vehicle due to fear of secondary accidents after the vehicle goes wrong, so that rear drivers cannot respond timely, and more serious traffic accidents are caused.
