The system to single-chip microcomputer as the core, through the stepper motor to achieve trajectory control. System consists of motor drives, black and white line detection, human-computer interaction as well as four single-chip controller parts. System using two single-chip, one for W78E58B, through accurate algorithm to realize the direct control of stepper motor another piece for the AT89C51, for voice playback, two single-chip 485 communication between the networking. In addition, the DS1232 watchdog applications, improve the single-chip control system anti-interference ability.
