Hardware system includes a pulse signal generation, pulse signal processing and display module, using the C programming language, high accuracy ，the method is simple, good stability. In industrial buildings, often encounter many local motor parameters to be measured, for example, in testing, operation and control of electric motors, winches, engines and other devices, the regular use of continuous measurements or time-sharing and display its speed and efficiency. To the parameter of electric machine , we must first solve sampling problems. In this design uses a ITR9608 photoelectric switches for motor speed signal. Using the measured current and voltage conversion interface ADC0809. In order to accurately measure the speed, but also to ensure the real-time measurement of the parameter of electric machine can be measured by the method, and therefore the parameter of electric machine is of great significance.
