Description

Drunk driving warning system

The invention relates to a warning system, in particular to a drunk driving warning system capable of issuing a warning when a driver drunk.

Referring to FIG. 1, there is a conventional drunk driving warning device 70. As shown in the Republic of China New Patent Publication No. 178879, the drunk driving warning device 70 is mounted on a vehicle 71 and has an alcohol concentration of 72 in a driver 72. When a predetermined amount of safety is exceeded, a warning light 73 on the front and rear of the vehicle 71 is activated to alert the passerby and other drivers, and a warning sound is issued to the driver 72 in the vehicle 71 to alert the driver 72.

However, although other drivers can avoid the vehicle 71 and drive carefully when receiving the warning light 73 of the vehicle 71, there is still a considerable amount of pedestrians whose general traveling speed is relatively slow and the line of sight is only within the walking range. The danger is highly likely to be evasive because the warning light 73 of the drunk driving vehicle 71 is not noticed.

Another example is the traffic warning system (not shown) of the Republic of China New Patent No. M406236. The warning system adds radar speed measurement and warning functions to the traffic lights. When there is a driving speed that is too fast or a drunk driving causing a red light, In the red light lane, a flashing light will be given and the green light will be given. The lane will also give a flashing light warning to remind passersby to be careful.

However, although this kind of prompting method can make the driver of the driving car notice the warning of the front flashing light, and then drive carefully or avoid the vehicle with the red light, most of the pedestrians do not notice the state of the traffic light at a relatively high position, but still There is a risk of a vehicle being hit by a vehicle that is illuminated by a red light.

Because the existing warning system can only play a warning role for other drivers who are also driving, but for pedestrians who generally walk on the road with limited vision and slow speed, there are still people who can not notice the warning and still be injured. Danger.

Therefore, the object of the present invention is to provide a driver who drives a car, a knight who rides a bicycle, and a pedestrian, and can play a warning role when there is a drunk driving vehicle, so as to achieve immediate avoidance and avoid danger.

Thus, the drunk driving warning system of the present invention comprises at least one detecting device, one control device, and a plurality of warning devices.

The detecting device is installed in a vehicle for sensing the alcohol concentration of the driver, and can output a detecting signal when the alcohol concentration exceeds a preset value of the concentration.

The control device is disposed at a roadside and includes a signal receiving unit, a warning transmitting unit, and a processing unit electrically connected to the signal receiving unit and the alarm transmitting unit. The signal receiving unit is configured to wirelessly receive the detection signal and transmit the detection signal to the processing unit, and the processing unit receives and outputs a control signal to the alarm transmission unit according to the detection signal, the alarm The transmitting unit receives and outputs a warning signal according to the control signal.

Each of the warning devices includes a warning light unit mounted on the road surface of the road, and a trigger unit electrically connected to the warning light unit. The trigger unit receives the warning signal and outputs a trigger signal, and the warning light unit receives and switches between a blinking state and a closed state according to the trigger signal.
