When, solar panels can be holded up automatically to be come, to prevent accumulated snow too many, is damaged solar panels by pressure, can also be allowed when rainy day
Rainwater can fall directly on ground, rather than photograph on solar panel.After the sun sets, solar panels can also be holded up automatically
Come, and waits the sunlight direction of illumination of the next morning and rotate.Stepper motor is using turbine and worm type self-locking type
Stepper motor, controllor for step-by-step motor using：86BYG250D electric current 7.2A, long 118mm, diameter of axle 14mm, keyway 5*25,
Motor button power 8.5N.m driver, micro-stepping are subdivided into 14 kinds, and step number is 51200 steps/turn；Current range 2.0A-7.2A, has
Semi-fluid, over-voltage, overcurrent/etc. protection circuit.Supplied by AC/DC electricity, voltage range AC18V-60V, DC18V-80VDC.Solar energy
The sensor of lighting angle is to have used four BH1750 intensity of illumination sensors.
Operational process of following spot is as follows：System automatically resets when starting, and optical sensor is started to work, and the parameter acquisition is real
When be transmitted to master controller, each acquisition parameter all once judges, if acquisition is sent, if not then continues to send,
Guarantee the integrality of data, master controller carries out parameter to judge whether to angle adjustment, was adjusted, and sentenced to X-axis before this
It is disconnected whether to capture light source, it if it is continuing to run, is adjusted if not to Y-axis, then judge whether to capture light source, if
It is that then system continues to run, looping to determine again and again, guarantees that solar panels are transported under optimum illumination intensity always like this
Row guarantees solar panels generating efficiency.
