基于STM32的汽车行驶记录仪的设计与实现
摘要
汽车行驶记录仪是一种电子式记录设备,它对车辆行驶的时间、速度、里程以及车辆行驶的状态信息进行采集、记录、存储。汽车行驶记录仪的使用,对疲劳驾驶、超速行驶等驾驶员不良驾驶****惯能够起到约束作用,对保障车辆的安全行驶,分析和鉴定交通事故原因上具有重要的作用。
本次设计中设计了一款基于STM32的汽车行驶记录仪,主要采用STM32F103单片机为主控单元,以OV7670摄像头模块为图像采集模块,以SD卡位数据存储模块。控制系统以一定的间隔收集摄像头模块采集到的图像数据,并进行存储,实现实时的图像收集;通过将SD卡插入电脑端即可对系统实时拍摄并存储的图像信息进行查看。除此之外,可以通过串口工具实时监控系统的数据传输过程,使得抽象的数据采集、数据存储、数据调用变的更加形象、具体。本次设计的汽车行驶记录仪具有实时性好,可靠性和性价比高的特点。

Research On Vehicle Traveling Data Recorder Based On STM32
Abstract
Vehicle traveling data recorder is an electronic recording device, its vehicle travel time, speed, mileage and vehicle status information collection, recording, storage. Bad driving habits vehicle traveling data recorder use, fatigue driving, speeding and so the driver can act as a restraint on the safe driving support vehicles, and has an important role in the analysis and identification of Accidents. The design based on the STM32 designed a vehicle traveling data recorder, mainly STM32F103 microcontroller as the main control unit to the camera module OV7670 image acquisition module to your SD Card data storage module. Control systems at certain intervals to collect the camera module to capture image data, and store real-time collection of images, we can insert the SD card to puter side of the system in real time and store the captured image information view. In addition, through the serial data transmission system monitoring tool for real-time, making the abstract data acquisition, data storage, data call image es more specific. The design of the car recorder with a real-time, high reliability, and cost characteristics.
Key Words:vehicle traveling data recorder ,Real-time monitoring, STM32, SD card
