Description

technical field [0001] The invention relates to an anti-drinking driving key, which belongs to the technical field of automobile keys.

[0002] In China, there are tens of thousands of traffic accidents caused by drunk driving every year, and more than half of the fatal accidents are related to drunk driving. A big "killer", the traffic law stipulates that drinking and driving refers to the driving behavior in which the alcohol content in the blood of the vehicle driver is greater than or equal to 20mg / 100ml and less than 80mg / 100ml. Or equal to 80mg / 100ml of driving behavior, when the blood alcohol content of the driver reaches 80mg / 100ml, the probability of traffic accidents is 2.5 times that of non-alcohol in the blood, and when it reaches 100mg / 100ml, the probability of traffic accidents is 4.7 times that of non-alcoholic blood in the blood, even in the state of a small amount of alcohol, the risk of traffic accidents can reach about 2 times that of the non-drinking state, so the danger of drunk driving is extremely large, the most commonly used method in the prior art It is the random inspection by the traffic police, and the drunk drivers are often severely punished, but some drunk drivers still have a fluke mentality when they do not meet the traffic police inspection, so it is easy to cause a catastrophe. Alcohol detection device is set on the car key, and then control key or vehicle switch etc. according to the detection result, but there are still some loopholes, so that the drunk driver can avoid being detected, for example, the drunk driver uses others to carry out alcohol detection, etc., so the existing technology The anti-drinking and driving key in still needs to be improved
