Step-by-step motor controlling interface of solar tracing instrument system and 2-D solar tracing instrument

The present invention relates to a solar tracker solar tracker system and a two-dimensional stepper motor control interface. The system comprises: a control signal output interface, the interface receiving the control signal, X, Y direction and the photoelectric switch control solar tracker; solar tracker dimensional stepper motor control interface comprising: a signal transmission section: an optical isolator and a computer printer port signal power boost long distance driving circuit interface, 9-pin connector; signal receiving portion: long distance transmission interface circuit, a control signal logic circuit, the horizontal direction and the pitch direction of the photoelectric switch of the circuit board. Solar tracker for observation of direct solar radiation and the beam of radiation, the two-dimensional solar tracker accurate automatic, continuous sun tracking observation claims, stepper motor control interface, implemented by a common computer, a two-dimensional solar tracking control instrument accurately track the sun purpose is to control the interface to direct the stepping motor 2 moving forward and reverse direction, applicable to other similar situations.
