Problems solved by technology

[0003] However, the setting of the traffic warning device generally needs to be placed manually. In the case of poor road conditions or surrounding environment, if the driver of the car coming from behind cannot avoid it, it will cause personal injury to the person who placed it.
When an accident occurs and people are injured, no one puts the traffic warning device in time.
At present, special vehicles or robots that automatically place traffic warning devices have been disclosed, but none of them can appear at the scene of the accident in the first place
[0004] Cones are a common traffic warning device. Placing cones is a more common and effective way to guide traffic flow. Manually placing cones or placing vehicles with cones has the disadvantages of high risk, low timeliness, and high cost.

Abstract

The invention discloses a device for preventing secondary accidents on a road, The device comprises a cone marking mechanism for warning, an unfolding mechanism connected with the cone marking mechanism for removing the cone marking mechanism from the fixture close to the roadside, a driving mechanism for driving the unfolding mechanism to unfold and a control mechanism for controlling the starting and stopping of the driving mechanism. The invention also discloses a combined control method for preventing secondary accidents on roads. The device is simple in structure and can automatically putthe cone mark in place in time to prevent the secondary accident. By controlling the device in combination, the drainage of other vehicles at the accident site can be realized and the safety performance can be improved.

Description

technical field [0001] The invention relates to the traffic field, in particular to a device for preventing secondary accidents on roads and a combined control method thereof. Background technique [0002] When driving on the expressway, when a vehicle breaks down, the driver will choose to pull over and stop for inspection, and set up a traffic warning device in the direction of the coming vehicle to remind the car coming behind to pay attention to avoiding. When a traffic accident occurs, it is also necessary to set up a traffic warning device in the direction of the coming vehicle to remind the rear vehicle to prevent the rear driver from coming over due to the speed of the vehicle, not responding in time, and hitting the accident vehicle to cause a secondary accident. The expressway has a large traffic flow and a fast speed. It is of great significance to set up traffic warning devices in time and effectively guide the traffic flow to reduce the probability of secondary ...
