摘　　要：控制器以8051单片机为核心,主要由密码保护、酒精检测及超声波测距防撞等三个子系统模块构成。密码锁系统设定四位十进制数为密码,增强了汽车的防盗性能。酒精检测用气敏传感器检测驾驶者呼气中酒精浓度,可有效防止酒后驾车。超声波测距防撞系统以超声波在空气中传播速度为已知条件,根据发射和接收的时间差计算出发射点到障碍物的实际距离,可预防追尾事件的发生。该控制器克服了传统控制装置功能相对单一、精度低、响应速度慢等缺点,具有广阔的应用前景。The core of the controller was 8051 single-chip microprocessor. The system was mainly made of three sub-system modules： password protection system, alcohol detection system and anti-collision system of ultrasonic distance-measurement. The lock system designed a password with four decimal digits as its code, and it enhanced anti-theft function of motor vehicles. Alcohol detection system used gas sensors to detect the driver＇s alcohol concentration of breath, which can effectively prevent the driver from drunk driving. The ultrasonic distance-measurement system taking the ultrasonic wave＇s propagation speed in the air as the known condition, according to the transmitting and receiving of the different time period, calculated the launch point barrier to the actual distance, and it may prevent the occurrence of rear-end events. The controller overcomes the shortcomings of the traditional controller, which is single function, low-precision, slow response, so the new muti-function controller can be widely applied in the future.
