摘要
本文介绍了AT89C51ED2在汽车行驶记录仪中的实现。该记录仪采用大容量闪速存储器FM1808作为存储载体,利用定时器中断方式来实现秒间隔的数据采集与存储,利用串行口中断方式实现与微机的数据通信,通过USBHOST和IC卡实现对车辆记录数据的快速下载和出行任务的灵活设置。
This paper introduces the vehicle recording system for safe driving,based on CPU of Model AT89c51ED2.The recording system adopts flash memory FM1808, with a large capacity of memory,as a deposit carrier,and collect and store intormation/data within second intervals by the means of timer interruption.And with the aid of COM interruption,the system implaments the data communication with computers,which accelerates the download of vehicle recording with USB HOST ＆ IC card and can set the tasks flexibly.
