Abstract: 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.
