防酒后驾车装置的研究

摘要

酒后驾车在我国目前所引发的交通事故,已经占到总数相当大的比例.为了从根本上防止司机的醉酒驾驶,研究了防酒后驾车装置.该装置由酒精钥匙和酒精检测装置两部分组成.它们分别在司机起动汽车时对司机呼出的气体进行检测以及正在开车的司机呼出的气体进行实时监控.如果检测到司机呼出的气体中酒精含量过高,前者会拒绝设计起动汽车;后者则会提醒司机减速停车.如果司机不减速停车,装置会自动将发动机熄火.因此,这种装置可从根本上防止醉酒驾驶的发生,从而避免了因司机醉酒驾驶而引起的车祸.%Traffic accidents caused by drunk driving in our country has accounted for a large proportion of the total. For fundamentally preventing driver's drunk driving, an anti-drunk driving device was researched.The device consists of two parts: alcohol key and alcohol detection. Their function is to detect exhaled breath of the driver when he ready to start the car or he was driving. If the driver be detected that alcohol concentration of his breath is too high, the former device will refuse to start the car; the latter will remind drivers to decelerate and stop. If the driver does not decelerate and stop the car, the device will turn off the engine automatically. Therefore, this device can fundamentally prevent the occurrence of drunk driving and avoid accidents caused by drunk driving.
