摘　　要：为了对转动装置的转速进行实时检测,研制出一种光敏Z-元件转速测量系统.应用光敏Z-元件设计了一种新型转速传感器,并利用该传感器构建了由转速采集、数据处理和数据显示等电路模块组成的测速系统电路.系统程序设计中采用分段采样法对计数误差进行修正,提高了转速测量系统的精确度.由于光敏Z-元件的特殊性质,测速系统具有精度高、响应速度快等特点.This kind of rotating speed measurement is designed by using light - sensitive Z - Element to measure the real -time rotating speed of rotary device. A new rotating speed sensor and rotating speed measurement circuits which consist of rotating speed acquisition, data process and display modules have been designed by applying the light - sensitive Z - Element. Counting errors are modified by picking up interval datum during designing system program so that the accuracy of system has been improved. System of measurement has the features of better accuracy and high response speed due to the special properties of the light - sensitive Z - Element.
