摘　　要：本文根据公安部颁布的汽车行驶记录仪国家标准的要求，采用μPSD3334D单片机为微处理器，从记录仪的主要功能和结构，软硬件的设计方面对汽车记录仪进行研究与开发，实现了汽车行驶记录仪的显示功能、按键操作功能和实时时钟等功能，能够方便地实现速度、里程的显示与存储功能．Vehicle traveling data recorder, VDR for short below, or named Vehicle black box, is a kind of digital electronic recording device, which is used for recording the status messages, such as speed, time, mileages and so on, of the vehicle and storing the information. After the national standard of Vehicle traveling data recorder promulgated in 2003 in our country, the study and application of VDR has attracted more and more attention. And it has used in some regions, which had had effect of lowing the traffic accident rate and improved the transport efficiency. This paper will introduce the study and design of VDR firmware according GB/T 19056-2003, which is based on ~PSD3334D ~l^ip microcomputer. And this VDR system sample has completed the display function, key handle function, real time clock and other functions that satisfied the GB/T 19056-2003 under the static condition also completed the measure, display and store speed and mileage function. Following the development of electron technology, VDR would be connected with GPS and network with wireless and so on.
