针对远程实验中步进电机的控制问题,对步进电机的驱动方法、通信方式、位置速率计算和安全控制等方面进行了研究,对实验过程中步进电机的远程控制策略及方案进行了归纳,提出一种基于AT89C52单片机、THB6128步进电机细分驱动器、光电编码器以及Web服务器的步进电机远程控制系统,采用在远程客户端实时操控并观察电机运作的方法,对系统中电机的操控响应情况及其运行时的位置速率进行了测试。研究结果表明,该系统具有较好的安全性和失步判断能力,能够实现电机的启停、变向、变速控制及位置速率的准确测量,满足远程实验中实验设备的过程控制需要。

Aiming at the problem of the remote control of stepper motor in remote experiments,the driving method,communication ways,position rate calculation,security control and other aspects of stepper motor was researched. According to the induction of remote control program,a remote control system based on AT89C52 microcontroller,THB6128 stepper motor subdivision driver,photoelectric encoder and WEB server was presented. A method that controlled and observed the motor real-timely in remote client was used to test the control response and the position and speed of running motor. The results indicate that the proposed system not only has good security and step-out judgment,but also can achieve the performances,such as the start-stop,adjustable direction and speed and accurate measurement of position and velocity,so it can meet the needs of process control of devices in experiment.
