the single chip microcomputer receives the illumination intensity which accords with the real night, controls the solar cell panel to rotate downwards and eastward, restores to the initial position, and switches off the stepping motor.
The wind speed sensor collects a wind speed signal and sends an interruption tracking signal to the single chip microcomputer, wherein the interruption tracking signal is generated when the wind speed is greater than a threshold value.
The single chip microcomputer outputs pulse signals, the pulse distributor and the power amplifier convert the control pulse signals into stepping motor driving signals, and the starting, stopping and positive and negative rotation of the two stepping motors are respectively controlled.
The condition according with the illumination intensity of the real night comprises the illumination intensity with the night count of 2; the method specifically comprises the steps that the illumination intensity detected by the illumination intensity sensor in the first period meets the condition of the dark night, the dark night count is 1, the illumination intensity detected by the illumination intensity sensor in the second period still meets the condition of the dark night, the dark night count is 2, and the condition of the illumination intensity at the real dark night is met.
Specifically, the single chip microcomputer serves as a control core, a pulse signal is output according to a set program through a designed tracking method and detected parameters, the control pulse signal is converted into a large enough stepping motor driving signal through a pulse distributor and a power amplifier, and the starting, stopping and forward and reverse rotation of the stepping motor are controlled respectively.
The illumination intensity that illumination intensity sensor gathered is the important foundation that the singlechip judged the working method, and the illumination intensity sensor in this embodiment adopts TSL2561 light intensity digital conversion chip, adopts digital signal output, and the interference killing feature is strong. Since TSL2561 uses a 16-bit digital output, its access conforms to standard I2C bus protocol, and STC89C52 with I2C bus controller, so I of STC89C522The clock line SCL (PB 6) and the data line SDA (PB 7) of the C bus are directly connected to SCL and SDA of the TSL 2561. The INT pin is connected with a PB5 pin with an external interrupt function of the singlechip. In this embodiment, when the light is strong, photoelectric comparison tracking is adopted, when the light is poor, time control tracking is adopted, and when the light is weak, automatic reset is performed.
In order to reduce energy consumption, the time for tracking the start of work is set in advance according to the change rule of sunrise time, and the time data acquired by the clock module in real time is compared with the preset work time so as to judge whether the work time is reached. And if the working time is up, starting the tracking program, and starting to control the illumination intensity sensor to acquire the illumination intensity of the surface of the current solar cell panel.
Because the sun takes 24 hours around the earth, the sun rotates 1 degree every 4 minutes averagely, in order to reduce the repeated adjustment of the tiny angles of the solar panel and reduce the energy consumption, the single chip microcomputer reads the data of the illumination intensity sensor every 4 minutes, judges the current time to be day, rainy days or night according to the illumination intensity, and enters the next step until the judgment is that the current time is not night. Wherein the standard of the dark night is that the illumination intensity is less than 3000Lux, the range of more than 3000Lux and less than 30000Lux is rainy days, and the range of the illumination intensity is fine days when the illumination intensity is more than 30000 Lux.
In the embodiment, the wind resistance is an important index for the photovoltaic array used in a windy area, and the wind speed sensor in the embodiment is used for selecting whether to interrupt the tracking program according to the wind power. The wind speed sensor adopts a voltage output type digital wind speed sensor NHSF45-U produced by Wuhan, and when the weather meets gale weather of more than 8 grades, the tracking is stopped, and the solar panel is kept still. And after the wind speed is reduced to a safe range, the tracking is recovered, and the target is not lost when the tracking is recovered.
Wherein, photoelectric sensor in this embodiment connects solar cell panel and signal processing circuit respectively, photoelectric signal conversion who will sense becomes the signal of telecommunication, transmit to the singlechip through the circuit, the singlechip calculates the current change that the shade leads to according to the sun position on the same day, confirm the sun position, and then judge whether solar cell panel is in the best angle of light intensity, find not will send the instruction to step motor and mechanical execution device in the condition of best light intensity department according to the judged result, give vertical steering wheel and horizontal steering wheel with the signal transmission, the angle of adjustment solar panel, make it reach best absorption angle with the sun light is perpendicular.
And when the wind speed is judged to be not at night, namely the wind speed signal is collected in the daytime or in rainy days, the wind speed sensor collects the signal every 4 minutes, when the wind speed is greater than the set value, the tracking program is interrupted, the next time of collecting the wind speed signal is waited until the wind speed is reduced to be lower than the set value, and the tracking is resumed. Then detecting the illumination intensity, selecting a tracking mode according to the illumination intensity to perform primary tracking: and starting photoelectric detection tracking in sunny days, driving the stepping motor to drive the photoelectric detector and the solar panel to move, starting searching and tracking the position of the sun, enabling the solar panel to be aligned with the sun, suspending tracking after the completion, stopping the stepping motor, and enabling the system to enter a waiting state until a signal of the illumination intensity sensor is received next time. And starting time control tracking in rainy days to enable the battery panel to rotate 1 degree in the horizontal and vertical directions respectively, and then entering a standby state. When the rainy day changes to sunny day, photoelectric tracking is adopted. If the judgment result is at night, no action is taken, the solar panel directly enters a waiting state, the solar panel is reset when the judgment result is at night twice, continuous pulse signals are output to enable the solar panel to rotate downwards and eastward, the motor power supply is cut off and fed back through a limit switch, then the tracking control circuit is cut off, and the clock sub-circuit power supply is reserved.
The clock circuit is kept on all the time, after the preset time is reached, the tracking program is started, the night counting is zero (the counting is used for resetting at night, and the counting is zero and does not indicate the day), and the illumination intensity is periodically detected.
Waiting for the next detection when the wind speed is judged to be in the dark, and starting to detect the wind speed when the wind speed is judged to be not in the dark. And (4) judging the wind speed, returning when the wind speed is greater than or equal to the set value, and continuing when the wind speed is less than the set value. Detecting the illumination intensity again, and judging the illumination condition, (1) judging the illumination intensity to be sunny, counting and resetting at night, starting the photoelectric tracking, stopping the motor after the tracking is finished, and entering a waiting state; (2) judging the illumination intensity to be in rainy days, counting and resetting at night, starting time control tracking, stopping a motor after the tracking is finished, and entering a waiting state; (3) and if the illumination intensity is judged to be at night, adding 1 to the night count, and then judging the night count. Since the number of counts at night is 1, the motor does not operate and waits for the next detection because of interference of the shielding object. And if the night count is more than 1, the solar cell panel is judged to be a real night, the solar cell panel starts to reset, the stepping motor drives the azimuth axis and the pitch axis to enable the solar cell panel to rotate to the east and downwards to a limiting stop position, then the tracking program is closed, and only the power supply of the clock circuit is reserved. Note that the height angle corresponding to the stop position is 0 during installation. The azimuth is the position where the local sun has the smallest azimuth in the year.
