介绍了一种8031单片机控制的实用型智能化的气缸速度检测系统，系统采用霍尔元件及相应的信号放大比较电路作速度传感器，给出了气缸速度的检测原理及检测系统的软硬件组成。实现了气缸绝对速度的自动在线检测，并可对异常速度进行实时调节或报警，保证了自动化机械的运行精度。
A practical and intelligent cylinder speed detection system controlled by 8031 MCU is introduced. The system uses the Hall element and the corresponding signal amplifying and comparing circuit as the speed sensor, and gives the detection principle of the cylinder speed and the hardware and software components of the detection system. The automatic on-line detection of the absolute cylinder speed is realized, and the abnormal speed can be adjusted or alarmed in real time to ensure the running accuracy of the automatic machine.
