摘要 汽车行驶记录仪是对车辆行驶速度、时间、里程以及有关车辆行驶的其他状态信息进行记录、存储并可通过接口实现数据输出的数字式电子记录装置。
记录仪对约束驾驶人员的疲劳驾驶、超速等不良驾驶行为，对预防道路交通事故的发生局域重要作用。记录仪便于道路运输企业及交通管理部门的科学管理，可以为交通事故的分析和公正处理提供科学、权威的原始数据。
介绍记录仪的研究背景、意义和国内外发展现状，叙述记录仪的定义、相关术语和组成等。
本文记录仪的主机位主要研究对象。本文的主要内容包括以下内容：
1）供电模块2）单片机系统3）信号采集模块4)实时时钟模块5)数据储存模块6)显示和键盘模块
详细论述驾驶员身份识别、实时时钟、车速、里程等数据采集单元的具体实现方法。阐述数据存储格式、液晶显示器和热敏打印机的设计。
