2、motor variable frequency speed regulation system based on PLC designAbstractHuman being is seriously threatened by exhausting mineral fuel, such as coal and fossil oil. As a kind of new type of energy sources, solar ene
3、rgy has the advantages of unlimited reserves, existing everywhere,using clean and economical .But it also has disadvantages ,such as low density,intermission,change of space distributing and so on. These make that the cu
4、rrent series of solar energy equipment for the utilization of solar energy is not high. In order to keep the energy exchange part to plumb up the solar beam,it must track the movement of solar. In this paper, the solar t
5、racking system of the mechanical part and control system part are designed.Mechanical structure mainly includes the main spindle, stepping motors, gears and gear ring, and so on. When the sun's rays has a deviation,
6、small gear are rotated by stepper motor according to the control signal from MCU. And the large gear and main spindle is rotated by small gear in order to track to achieve the level direction. At the same time, another s
7、mall gear is rotated by another stepper motor according to the control signal.And the large gear and the solar panels are rotated by the small gear in order to track to achieve the vertical direction. Solar is tracked by
8、 the two stepper motors together. Control system mainly includes the sensors part, stepper motor, MCU system and the corresponding external circuit, and so on. Photoelectric detection system is used to track solar. Senso
9、rs use photosensitive resistance. The two same photosensitive resistances were placed in east and west direction of the bottom edge .When the two photosensitive resistances received different light at the same time, the
