Hardware systems includs the pulse signal generation, pulse signal processing and display module, using C language programming,for this method is simple, high precision, stability good points .In engineering practice, often encounter a variety of situations need to measure speed, such as engines, motors, winches, machine tool spindles and other rotating equipment, testing, operation and control, often need time-sharing or continuous measurement and display of their speed and instantaneous speed. To speed, we must first resolve the sampling problem. Production speed in the use table-mode technology, the methods used tachometer generator, the generator is about speed and sensed axle shaft connected to the generator speed reflects the speed high and low voltage level. In order to accurately measure speed, but also to ensure real-time measurement, requires instantaneous speed can be measured approach. Therefore, the measurement speed is significant .Keywords : speed measurement SCM Photoelectric sensors Motor pulse摘 要IAbstractII1 概述11.1 数字式转速测量系统的发展背景11.2 本设计课题的目的和意义12 转速测量系统的原理22.1 转速测量方法22.2 转速测量原理33系统方案提出和论证54 系统硬件设计74.1 转速信号采集74.2 转速信号处理电路设计94.3 单片机AT89C51介绍104.4 最小系统的设计144.4.1复位电路144.4.2 晶振电路174.4.3 最小系统的仿真184.5 显示部分设计195 系统软件设计235.1 主程序初始化235.2 主程序流程图程序流程图25总 结27参考文献28致 谢29附录A 系统总电路图30附录B 系统总程序清单301 概 述1.1 数字式转速测量系统的发展背景目前国内外测量电机转速的
