Embodiment
A kind of solar automatic tracking system, comprises solar panel, electric power management circuit, photoelectric tube, single-chip microcomputer, motor-drive circuit and stepper motor; It is characterized in that solar panel is connected with electric power management circuit; Electric power management circuit is connected with single-chip microcomputer; Photoelectric tube is connected with driving circuit by single-chip microcomputer; Driving circuit is connected with stepper motor; Stepper motor is connected with solar panel.
Solar automatic tracking system of the present invention, described photoelectric tube adopts 3DU33 photoelectric tube, the 3DU33 photoelectric tube using sensitivity higher is as light-intensity test device, its photocurrent is greater than 2mA, emitter only need be connected in series very little resistance just can obtain can be collected voltage, and its response time <1ms, reaction velocity is fast.Described stepper motor adopts 5 line four phase decelerating step motor 28BYJ-48, and for four phase step motor, its working method can be divided into single 4 to clap, three kinds of working methods are clapped in two 4 bats, 8.Single 4 bats are equal with two 4 step angles clapped, but single 4 rotating torques of clapping are little.8 step angles clapping working method are single 4 bats and two 4 half of clapping, and therefore, 8 clap working method not only can keep higher rotating torque but also can improve control accuracy.Working method is clapped in design employing 8, and so 1 to clap the angle turned over be 0.08789 °/2=0.043945 °, further increases tracking accuracy.Described solar panel adopt the specification of cell piece to be 0.5V/1.2A.Described solar panel is provided with 8 solar battery sheets, and in order to enable system normally run in outdoor, design adopts solar panel and lithium battery to system power supply.When solar panel output power is inadequate, by lithium battery to system power supply; When lithium battery voltage is lower than 3.5V time, solar panel is to lithium cell charging; Otherwise by solar panel to system power supply.The reduction gear ratio of described stepper motor is 1:65.The course of work: install a photoelectric tube respectively in the centre position at solar panel edge, the angle being mapped to cell panel opposite side two photoelectric tubes according to solar irradiation is unequal, make the intensity of illumination of two photoelectric tube impressions different thus produce the photocurrent varied in size, convert light stream to voltage signal, by comparing the voltage signal after collection, control step motor rotates to the direction that voltage is large, realizes the object that solar panel follows sun rotation.
