Safety device for preventing vehicle from running red light and being overspeed

Abstract

The invention provides a safety device which can directly prevent a vehicle from running a red light or being overspeed and can effectively prevent accidents from occurring. The safety device comprises a sub-device which is used for preventing the vehicle from being overspeed, a sub-device which is used for preventing the vehicle from running the red light, and a central processing unit, wherein the two sub-devices are electrically connected with the central processing unit; the sub-device which is used for preventing the vehicle from being overspeed comprises a plurality of rolling units, a vehicle speed detection device and a voice reminding device; each rolling unit comprises a roller, a supporting frame, a ratchet, brake calipers and pawls, the two ends of the roller are roller heads, the roller heads are respectively connected with the supporting frame through bearings, one roller head of the roller is connected with the ratchet, the pawls are installed on the periphery of the ratchet and the brake calipers are installed on the two sides of the ratchet; the sub-device which is used for preventing the vehicle from running the red light also comprises rolling units, the central processing unit is electrically connected with a traffic light signal center and the central processing unit is simultaneously and electrically connected with the brake calipers; the vehicle speed detection device and the voice reminding device are electrically connected with the central processing unit.

Description

technical field [0001] The invention relates to a safety device for preventing vehicles from running red lights and speeding. Background technique [0002] Running a red light and speeding have always been illegal behaviors that the traffic department is strictly catching because these two behaviors can easily threaten people's lives. However, in the prior art, the main way to prevent vehicles from running a red light and speeding is to install a monitoring device on the road to monitor passing vehicles. Once the monitoring device detects a vehicle running a red light or speeding, it will take pictures of the vehicle through a high-definition camera to obtain evidence. Then send the relevant ticket to the violating driver in about a week, and let him pay the fine and deduct the corresponding points on the driver's license. There is a traffic accident while speeding, and obviously this prevention method is not helpful for the accident that has already occurred. To sum up, t...

However, in the prior art, the main way to prevent vehicles from running red lights and speeding is to install monitoring devices on the road to monitor passing vehicles. Then send the relevant ticket to the violating driver in about a week, and let him pay the fine and deduct the corresponding points on the driver's license. A traffic accident occurred while speeding, obviously this preventive method is useless to the accidents that have already occurred

In summary, the prior art lacks a safety device that can directly prevent vehicles from running red lights and speeding and effectively avoiding accidents.
