摘要
随着道路安全问题的日益突出，疲劳驾驶和酒后驾车成为交通事故的主要原因之一。本文提出了一种基于STC12C5A60S2单片机的疲劳酒精检测安全驾驶系统设计，旨在降低交通事故的发生率，提高驾驶安全。该系统通过集成多种传感器和控制模块，实现了对驾驶员状态的实时监测和管理。
系统的主要功能包括：利用DHT11传感器检测驾驶环境的温湿度，确保驾驶员处于舒适状态；通过MQ-3传感器检测驾驶员呼出的酒精浓度，一旦超过预设的安全值，系统将通过声光报警提醒驾驶员；系统还具备定时器功能，能够记录驾驶员的驾车时间，若超过设定的最大时间，同样会发出声光报警，以防止疲劳驾驶；通过按键设置，管理人员可以轻松调整酒精浓度和驾车时间的阈值；LCD1602显示屏用于实时显示各监测数据，方便驾驶员和管理人员查看；蓝牙模块将所有监测数据实时发送到手机端，便于管理人员远程监控和记录。
经过实际测试，本系统能够稳定运行，有效提升驾驶安全水平。其智能化设计不仅提高了监测工作的便捷性，还为道路安全提供了有力的技术支持。

ABSTRACT
With the increasing problem of road safety, fatigue driving and drunk driving have become one of the main causes of traffic accidents. This paper presents a design of safety driving system for fatigue alcohol detection based on STC12C5A60S2 microcontroller, aiming at reducing the incidence of traffic accidents and improving driving safety. By integrating various sensors and control modules, the system realizes real-time monitoring and management of driver status.
The main functions of the system include: using DHT11 sensor to detect the temperature and humidity of the driving environment to ensure that the driver is in a comfortable state; Through the MQ-3 sensor to detect the driver exhaled alcohol concentration, once exceeds the preset safety value, the system will remind the driver through sound and light alarm; The system also has a timer function, which can record the driving time of the driver. If the maximum time is exceeded, the audible and visual alarm will also be issued to prevent fatigue driving. With a button setting, managers can easily adjust alcohol levels and driving time thresholds; The LCD1602 display screen is used to display the monitoring data in real time, which is convenient for drivers and managers to view; The Bluetooth module sends all monitoring data to the mobile phone in real time, which is convenient for managers to remotely monitor and record.
Through the actual test, the system can run stably and effectively improve the level of driving safety. Its intelligent design not only improves the convenience of monitoring work, but also provides strong technical support for road safety.
Keywords: fatigue driving, alcohol detection, temperature and humidity monitoring, LCD1602 display, driving safety
