摘要
基于超声波测距原理,通过AVR单片机芯片计算出道路车辆的实时速度以及车流量。采集到数据后,通过无线模块NRF24L01发送到PC端,在PC上用VB开发上位机,从而显示出实时曲线,道路信息。介绍了系统的硬件及其软件的整体设计理念,注意事项,同时给出了该系统的应用前景。
Based on the principle of ultrasonic distance measurement through the AVR microc ontroller to calculate the speed of road vehicles as well as real-time traffic flow data collected by the wireless module NRF24L01,sent to the PC side.Softwa re developed with VB,which can show the real-time curve,road information.Thi s article introduced a system＇s overall hardware and software design concepts,c onsiderations,and gave the system＇s prospect.
