The invention discloses a drunk-driving-preventing automobile safe driving system, which adopts a method of actively exhaling air by a driver to judge whether the driver drives after drinking or not,and is placed at the position of an automobile instrument panel; when the driver starts an automobile, the driver blows air to the system, and a sensor detects the alcohol to generate a voltage signaland amplifies the voltage signal; the 8-bit A / D converter converts the the voltage signal into a digital signal, the single-chip microcomputer processes and judges the digital signal, when the detected alcohol content does not exceed the standard, the relay is controlled to turn on the ignition device, the automobile can be started, and when the detected alcohol content exceeds the standard, thebuzzer gives an alarm, the detection indicating lamp is turned on, and the relay is controlled to cut off a power supply of the ignition device. The drunk-driving-preventing automobile safe driving system is designed for preventing drunk driving, is installed on an automobile, achieves automatic measurement, is high in intelligent degree and low in power, has a good effect on drunk driving prevention, and has good popularization value in practical application.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an anti-drunk driving automobile safety driving system. Background technique [0002] The stimulation of alcohol makes people excited when drinking, and they will drink too much without knowing it. When the alcohol reaches a certain concentration in the blood of the human body, people's ability to respond to the outside world and control ability will decline, and the ability to deal with emergencies will also decrease. the decline. For drunken driving, the alcohol content in their blood is higher, and the probability of crashing occurs is greater. [0003] When the alcohol content in the driver's blood reaches 80mg / 100mL, the probability of a traffic accident is 2.5 times that of a driver without alcohol in the blood; when it reaches 100mg / 100mL, the probability of a traffic accident is 4.7 times that of a driver without alcohol in the blood . Even under the state of low a...
