After sensing the body alcohol concentration 22 of the driver 8, the gas suction module 30 can extract the body gas of the driver 8 in the accommodation space of the drunk driving prevention device 1 to the outside of the drunk driving prevention device 1.

When the alcohol concentration sensor 20 compares the body alcohol concentration 22 in the vehicle 100 with the body alcohol concentration threshold TH2 to determine that the body alcohol concentration 22 has reached the body alcohol concentration threshold TH2, the alcohol concentration sensor 20 instructs the vehicle 100 The driver 8 stops driving the vehicle 100. At the same time, the alcohol concentration sensor 20 can be connected to the server 40 to transmit the sensed body alcohol concentration 22 and the comparison result with the alcohol concentration threshold TH2 to the server 40 for storage.

For example, the alcohol concentration sensor 20 outputs, for example, a sound-prohibited vehicle signal by playing sound, light, or text to remind the driver 8 not to continue drinking, or instruct the driver 8 to stop driving the vehicle 100 immediately or to stop driving. Driver 8 moved to the nearest safe place to park. Alternatively, the alcohol concentration sensor 20 controls the gasoline-electric system of the vehicle 100 such as an engine to directly force the vehicle 100 to be cut off from oil and power, and forcibly prohibit the vehicle 100 from starting.

In the embodiment of the present invention, the alcohol concentration threshold TH2 in the body is different from the environmental concentration threshold TH1, and the alcohol concentration threshold TH2 in the body is lower than the alcohol concentration limit standard prescribed by law. In this way, the alcohol concentration sensor 20 instructs the driver 8 of the vehicle 100 to stop driving the vehicle 100 before reaching the alcohol concentration threshold TH2 in the body and exceeding the alcohol concentration limit prescribed by the law to effectively prevent accidents such as a car accident.

The server 40 can provide the environmental alcohol concentration 21 and the comparison result with the environmental alcohol concentration threshold TH1, and the body alcohol concentration 22 and the comparison result with the alcohol concentration threshold TH2 to the police station system 50. The police station system 50 is provided to a police unit 60. The police unit 60 may dispatch police force to arrest the vehicle 100 and its driver 8 when, before, or after the driver 8 of the vehicle 100 exceeds the alcohol concentration limit prescribed by law.

As described above, this embodiment is divided into two phases of alcohol sensing methods: sensing and blowing. In detail, the alcohol concentration in the environment of the vehicle can be sensed by the alcohol sensor at any time, and when the environmental alcohol concentration threshold is exceeded, the driver enters the second stage, and the driver blows the alcohol sensor, and Sensing the alcohol concentration in the driver's body and requesting to stop driving the vehicle when it is judged that the threshold of alcohol concentration in the body is exceeded.

With the above method of this creation, the driver only needs to blow on the alcohol sensor when the alcohol concentration in the environment is too high, to more accurately and instantly detect whether the alcohol concentration limit is about to be exceeded, which is very convenient to use. Not only can save the personnel costs of many police personnel, reduce the workload of police personnel, the driver will not be stopped on the road, such as temporary inspection, and affect the driver's travel time, resulting in traffic congestion, but also in the coming Before exceeding the alcohol concentration limit, prevent traffic accidents caused by drunk driving.
