摘　　要：设计了一种实时检测司机酒精含量的报警系统,通过压力传感器检测是否有人驾驶,以MQ-3酒精传感器检测酒精含量,采用GPS作为定位模块,卫星接收车辆实时位置并存入EEPROM中,单片机读取信息并通过LCD1602显示经纬度,时间日期和酒精含量,通过ISD1420实现语音报警。系统在酒精量超标的情况下制动机车,同时通过GPS定位把车辆的精确位置通过GSM网络以短信的形式实现远程报警。经测试表明,系统稳定可靠,功能齐全,具有较好的推广价值。Alarm system for real-time detection of the alcohol content of the driver is designed. System can detect whether someone driving by a pressure sensor. Using GPS as the positioning module, the system can real-time receives the location information of the vehicle, and deposits in EEPROM. MCU reads the information and through the LCD1602 display longitude and latitude, date and time and alcohol content, and can realize voice alarm by ISD1420. If the alcohol content exceeds the standard, the system can pat on the brake of automobile, at the same time, through GPS positioning the accurate position of the vehicle through the GSM network to send text messages, realizes the remote alarm. According to the test results, device is stable and reliable, complete functions, and has a good popularization value.
