摘要
介绍了利用单片机系统实现对行驶在高速公路上的汽车进行实时监测,给出了单片机控制系统的硬件和软件设计的基本思想.采用MPM380压力传感器来采集汽车行驶信号,并启动或停止定时器来获得汽车行驶1米路程所需要的时间,通过查表的方法来确定其速度,使测速仪具有自动警告功能和快速捕捉超速车辆速度的能力.
The article introduces that how to make use of MCS51 single-chip controller system achieving monitoring the velocities of the vehicles on the super highway for real-time, and provides the basic design of the hardware and the software. The system adopts two MAM380 to sample signals of running automobiles, then according to the signals starts or stops the Timer/Counter to acquire the time by which the vehicle passed the one meter distance. It could carry out the velocity by method of searching the programme. The instrument of measure speed has the ability of warnning the drivers that their automobiles have been exceeding speed limit, and displays the velocity on the monitor.
