The system has strong anti-interference capability. High safety and easy to operate. 3. On the basis of hardware design, based on Linux platform and C language, the driver of Linux real-time operating system, USB LCD touch screen, network and other peripheral interfaces is designed, and the application program framework based on multithreading technology is built. A man-machine interactive system is developed on Qtopia platform, which includes user login, network management, information extraction, equipment control and so on. Experimental results show that the solar photovoltaic automatic tracking system based on ARM achieves the function and technical specifications of the design requirements, and has the characteristics of high stability, accuracy, networking, low cost, low power consumption, convenient operation, etc. It can make up for the deficiency of the existing automatic tracking system and has certain reference value for its wide application in practice.
