| Abstract: | 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. |
