摘 要

随着科技的发展、社会的进步，极大的方便了人们的衣食住行，越来越多的汽车进入企业、家庭，随之而来的问题也日益出现，尤其是行车安全问题。Android行车记录及提醒仪相当于“黑匣子”，是一种数字式电子记录装置,可以对车辆行驶速度、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。它可以全程记录汽车行驶数据，并通过对所记录的行驶信息数据进行分析，从而对车辆的各种状况予以精确的掌控，可为交通事故提供证据。

因此，设计一款行车记录及提醒仪APP便可以解决行车安全中的一些需求，如有效地解决了事故发生时的证据资料不足问题。该应用系统集疲劳提醒、限速提醒、行车安全提醒、前车起步提醒、开大灯提醒、视频管理等功能于一体，充分满足了行车过程中的对事故资料、碰瓷情况的需要。

The driving record and alerting device for Android phones

ABSTRACT

With the development of science and technology and the progress of the society, great convenience to the daily life of people, and more and more cars into the enterprise, the family, the resulting problem is increasingly appear, especially the safety issue.The driving record and the reminder like the equivalent of a "black box", is a digital electronic recording device ,the speed, time, mileage and other status information about the vehicle can be recorded, stored, and can be exported through an interface. It can record all the car data, and the analysis of the recorded information of data, and conditions to be precise control of the vehicle, can provide evidence for the traffic accident.

Therefore，the design of a driving record and a reminder device can be used to solve some ofthe requirements in driving safety, such as effectively solving the problem of insufficient evidence in the event of an accident. The application system combines the functions of fatigue reminder, speed limit reminder, safety warning, starting warning, Bright lights to remind and video management,It fully meets the needs of the accident data and route navigation in the course of driving.

Key words: The driving record and the reminder、APP、Android、Traffic warning
