In this article, a reliable design model and electric hardware for automobile black-box arepresented. aoppler effect, a well-known noncolltacts measuring method, for detecting brake ve locity is described in more details. Based on experimental equipment which is built for detectingbrake velocity, a higher precision and more practical results are proVed to be reached for automo bile black-box.

本文提出了汽车事故记录仪的设计思想及给出了其实现电路硬件设计方案详细阐述了汽车事故记录仪中用于测量于刹车速度的非接触测量方法──多普勒效应测速法.并以实验装置为依据,给出了实验数据,证明了该测速法用于汽车事故记录可行性和高精度的结果.

Most current Automobile Black Boxes (event data recorders) treat the wheel linear speed as driving speed.But in case of wheel lock or skid which often happens in crash accident,the wheel speed cannot truthfully reflect the driving speed.In this paper the authors propose a new method for measuring driving speed with a low cost acceleration sensor (such as ADXl05 sensor).By integrating the measured acceleration,an approximate driving speed can be calculated when skid occurs.The idea is implemented on a prototype system developed with C8051F320 micro-controller.The test results show that the measurement error of driving speed is acceptable for engineering applications and the total system is of low cost and can be easily calibrated....

目前,汽车行驶记录仪普遍将车轮转速记录为汽车行驶速度,但车轮抱死时,车轮速度不能真实反映汽车行驶速度。本文介绍一种由美国Cygnal公司的超低功耗C8051F系列的F320型单片机组成的记录仪系统,其中增加低成本的加速度传感器(美国AD公司的ADXL05微型力平衡式加速度传感器)记录制动时的汽车减速度,再依据制动时车轮初始速度及实测的加速度梯形公式计算汽车行驶速度。试验研究表明:行驶记录仪易标定、车速误差小、成本低、供电简单。

Automobile black box is one of the focuses in current research field. It can write down accurately the relevant parameters while the automobile is in the state of running, offers a high-efficient and reliable (management) platform for vehicle administrative department.This paper introduces the design of display module in automobile black box based on AT89C55 micro-controller, including the designs of hardware and software.
