摘要
本文介绍了一种利用GPS技术动态检测道路交通区间测速监测系统的检定装置,它采用C8051F500单片机作为主控芯片,利用CAN总线与GPS传感器进行通信。单片机对GPS传感器数据信号处理并获取实时时钟、车辆运行速度及里程信息,然后送与车辆外挂的显示屏进行显示或打印输出,进而检定与校准区间测速监测系统。该检定装置在检定实验中表现出良好的稳定性和可靠性,其各项技术性能指标均满足精度要求。
A test device for dynamic detection of road traffic interval velocity monitoring system using GPS technology is introduced in this paper. It uses C8051F500 microcontroller as the main control chip, it communicates with GPS sensor by CAN bus. GPS sensor data signals, processes by the microcontroller, which can acquire real time clock, vehicle running speed and mileage information. And then it is sent to the vehicle plug-screen display or print output. The interval velocity monitoring system is further tested and calibrated. The verification device shows good stability and reliability in the verification experiment, all the technical performance indexes meet the requirements of accuracy.
