摘要
利用霍尔速度传感器和嵌入式软硬件结合,实现一个具有采集、显示和记录车辆的行驶速度,监控车辆超速等异常情况以及下载历史数据功能的车辆速度显示记录系统。该系统以AM335X作为主控芯片,结合霍尔速度传感器、串口屏、报警模块和存储模块构成,以C语言为编程语言在PC上编程然后移植到目标板上验证运行,实现车辆速度的显示和记录。该系统的功能概况为:采集、显示和记录车辆的行驶速度,监控车辆超速等异常情况以及下载历史数据。
A Hall-effect speed sensor and embedded software and hardware are combined to realize a vehicle speed display and recording system with the functions of collecting, displaying and recording the speed of the vehicle, monitoring the abnormal speed of the vehicle and down- loading the historical data. The system takes AM335X as the master chip, combines Hall speed sensor, serial port screen, alarm module and storage module to C language programming language programming on the PC and then ported to the target board to verify the operation of the vehicle speed display and recording. The system＇s functional profile is： acquisition, display and recording of vehicle speed, monitoring of vehicle speeding and other anomalies and download historical data.
