摘要
近年来﹐随着我国汽车的普及,汽车的安全问题已经引起了我们的注意,根据最新的数据显示，目前,酒后驾车成为车祸频发的主要原因,我国因酒后驾车而导致的死亡人数平均每年以7.3%的速度增长，酒后驾车轻则害人害己，重则车毁人亡。为了防止酒后驾车,设计一种智能电路来检则驾驶员体内的酒精含里并且能够及时切断汽车电源是非常有必要的。
该设计由MQ-3酒精传感器来测里饮酒后驾驶员体内的酒精浓度，将信号传入单片机﹐最后由单片机通过对数字信号的处理来显示酒精浓度。在超过阈值时，发出声光报警，并且通过控制继电器来切断汽车电源。软件方面，各个子程序的功能相对独立，便于调试和修改。当驾驶员体内酒精浓度超标时，该系统能够自动切断汽车启动系统电源，同时发出声光报警﹐并通过数码管实时显示酒精浓度。

Abstract
In recent years, with the popularity of cars in China, the safety of cars has attracted our attention. According to the latest data, drunk driving has become the main cause of frequent traffic accidents. The number of deaths caused by drunk driving in China has increased at an average rate of 7.3% every year. Drinking driving can cause harm to others and others, and it can lead to vehicle destruction and death. In order to prevent drunk driving, it is necessary to design an intelligent circuit to detect the alcohol content in the driver’s body and cut off the power supply of the car in time.
In this design, MQ-3 alcohol sensor is used to measure the alcohol concentration in the driver’s body after drinking, and the signal is transmitted to the microcontroller. Finally, the microcontroller displays the alcohol concentration by processing the digital signal. When the threshold value is exceeded, an audible and visual alarm is given, and the vehicle power is cut off through the control relay. In terms of software, the functions of each subprogram are relatively independent, which is convenient for debugging and modification. When the alcohol concentration in the driver’s body exceeds the standard, the system can automatically cut off the power supply of the car starting system, give an audible and visual alarm, and display the alcohol concentration in real time through the digital tube.
