摘要
为实现对高速公路机动车行驶速度的全程监测及预警,设计了一种以C8051F330为控制核心的机动车速度监测及无线传输系统;详细叙述了系统设计原理与软硬件的实现方法,系统利用C8051F330单片机控制传感器实时采集机动车行驶速度信号并进行处理,通过RFID标签和读写器无线传输车辆速度、身份信息以及前方路况限速信息,从而实现对高速公路机动车速度的实时监测和预警功能;实验调试表明系统反应速度快、运行可靠且成本低,具有良好的应用前景。
In order to achieve the real-time monitor and the warning of vehicle speed in highway,a wireless transmission system and vehicle speed monitor based on C8051F330 acting as a control core were designed.The principle of the system and the design of hardware and software were introduced in detail.The vehicle speed was acquired and processed in real-time by the speed sensor controlled by the C8051F330 in the car.The system realized the real-time speed monitor and alarming through the RFID tags and readers which could transmit vehicle speed,ID information and limited speed wirelessly.The experiment shows that the system has merits of low cost,fast response,reliable operation and a very good prospect of application.
