[Abstract]:The embedded photovoltaic automatic control scheme based on ARM11 processor is composed of solar photovoltaic panel, photoresistor, photodiode, motor, solid sliding bracket and ARM11. By comparing the size of photosensitive resistor, the system makes full use of the biological principle of three-eye insects to recognize light. With the help of three-dimensional sliding support, a single ARM11 system controls multiple motor drivers and drives the motor to rotate automatically. Make multiple solar photovoltaic panels and solar light to maintain the best angle. The experimental results show that the system can not only improve the utilization rate of solar energy, but also save a lot of cost. The main contents and achievements of this paper are as follows: 1. Aiming at the problem that the solar photovoltaic panels cannot make full use of the sun in azimuth fixing, this paper designs an embedded tracking system based on the research of the theory of solar photovoltaic tracking technology. In the study of this system, the biological principle of three-eye insect recognition light is put forward, and the principle is applied to this system. The flexibility of embedded system is based on the geometric characteristics of equilateral triangle and the principle of physical mechanics. The experimental results show that the design can make solar photovoltaic panels and solar light keep a suitable position quickly, not only make full use of solar energy, save the cost, but also greatly expand the application field of solar photovoltaic panels. 2. According to the characteristics of embedded system, the circuit design of this paper adopts essential security technology, low cost and low power consumption design. Samsung ARM11 microprocessor S3C6410 is chosen as the control core of the system. A 51 board, 2 stepper motors, 1 controller and 1 battery are designed to complete automatic tracking, information storage and USB transmission, network communication and other functional modules. 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.
