Embodiment Construction

[0017] A detection system for preventing drunk driving, comprising: a pressure sensor 1 is connected to a central processing unit 6 through a signal amplifier 2 and an A / D converter 3; an alcohol detection sensor 5 and an engine ignition system 10 are connected to the central processing unit 6 respectively. The CCD camera 7 is connected with the central processing unit 6 . The central processing unit 6 is connected to the GPR / Beidou positioning device 8 in wireless communication, and the GPR / Beidou positioning device 8 is connected to the mobile communication device 9 in wireless communication. Alcohol detection sensor 5) is installed in the center of steering wheel 4. The pressure sensor 1 is installed directly below the driver's seat. The signal amplifier 2 is a triode signal amplifier.

[0018] The specific working process: (1) When the central processing unit 6 detects the signal from the pressure sensor 1, the central processing unit 6 will order the CCD camera 7 to tur...

Abstract

The invention discloses a detection system for preventing drunk driving and a control method thereof. The detection system is characterized by comprising a pressure sensor (1), a signal amplifier (2), an A / D converter (3), a central processor (6), an alcohol detection sensor (5) and an engine ignition system (10), wherein the pressure sensor (1) is connected with the central processor (6) through the signal amplifier (2) and the A / D converter (3); the alcohol detection sensor (5) and the engine ignition system (10) are connected with the central processor (6). A large scale integrated circuit is adopted in the detection system, modularization is achieved, and the structure is made to be simple. By means of the detection system, it can be guaranteed that a drunk driver cannot start an automobile, and traffic accidents caused by drunk driving are decreased. Meanwhile, the problem that the drunk driver starts the automobile by resorting to deceit is solved.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a device for preventing drunk driving. Background technique [0002] With the rapid development of the economy, the family car gradually enters every family. While bringing convenience to everyone to go out, it also makes the behavior of drunk driving more and more prominent. Especially in recent years, the rate of traffic accidents caused by drunk driving has increased sharply, which has brought huge losses to the country and the victim's family. The country has also promulgated corresponding laws and regulations to prohibit drunk driving for this reason. Although these regulations have played a certain role, these regulations only play a certain role on the road sections where guards are often set up to check drunk driving. For road sections where guards are not frequently set up to detect drunk driving, some drivers will not obey traffic laws. [0003...
