Application of subdivision stepper drive in solar tracking system
In order to make efficient use of solar energy, according to the law of solar operation, combined with photoelectric sensor design with single chip microcomputer as the core Solar automatic tracking system. Firstly, the hardware design and software implementation of system control are carried out, and then the stepper motor is analyzed and compared deeply Effect of general drive and subdivision drive on automatic tracking accuracy of solar energy. The results show that the system with the general drive method is used Compared with the solar automatic tracking system with stepper motor subdivision drive, the tracking accuracy is high, and the solar energy utilization rate is effectively improved.
