| 摘 要： | 介绍了一种由89C51单片机与82C53计数器组成的高精度测速系统.通过系统外围电路和控制软件设计,采用单片机在两次中断中开启和停止定时器,实现了对电机转速脉冲信号任意个完整周期的精确测量;克服了82C53计数器由于打入计数初值原因,随机地产生系统少计或多计一个脉冲的情况.最后以Agilent公司生产的高精度信号发生器为基准对该系统进行了速度测量模拟实验,并对实验结果进行了分析.结果证明,该测速系统具有测速精度高,测量范围宽的优点.

| Abstract: | A kind of high precision speed measurement system was introduced.By designing of outer circuit and control software,the arbitrary whole period was measured accurately in two interrupts by starting and stopping timer.The situation of differencing one pulse caused by writing the initial value to 82C53 counter was overcame.The speed measurement simulation experiment was done by using high precision arbitrary waveform generator produced in Agilent company,and the experiment results were analyzed.Result shows that the system has the advantages of high precision and wide range. |
