Abstract
Provided is a sunshine illumination control device. The sunshine illumination control device comprises a single-chip machine system, a circle distributor and a driving stage circuit. The single-chip machine system generates pulse signals, after the circle distributor receives the pulse signals, the signals are carried out amplification and processed, then driver stage circuit processing is carries out, and finally the signals work through a power amplification drive stepping motors to operate. The single-chip machine system is in charge of processing an event procedure of a stepping motor system such as an accelerating or decelerating keystroke handling, a speed display function, storage of control parameters as well as producing a pulse to control a corner, a revolving speed and a changing direction of the stepping motors. An AT89C52 chip is adopted by the single-chip machine. A movable reflection mirror controls the movement in two directions of x and y through the two stepping motors. Due to the fact that the open ring operation of the stepping motors are controlled by time and the open ring operation frequency and the distance of the stepping motors are additionally added, the stepping motors are driven to work by power amplification so the method enables a rotational movement to be simple and feasible.

Described single-chip microcomputer adopts the AT89C52 chip;
Mobile speculum moves by two step motor control x, y both direction, and design is owing to being that to control by the time open loop operation of adopting stepper motor be by adding given running frequency, range ability etc., moving by the power amplification Driving Stepping Motor.
Design uses ring distributor to control the rotation of speculum, ring distributor is used for receiving pulse and the rotating mode signal that sends from SCM system, and produce by the sequence of states in the stepper motor state transition table signal that control respectively is conducted or ends, whenever CP pulse of ring distributor reception, its output is just changed once.Therefore, we can be by the frequency of control impuls, change the stepper motor rotating speed height, raising speed or reduction of speed, start or stop, simultaneously, the direction control signal that ring distributor is also exported according to SCM system, the state that determines output is by positive sequence or inverted sequence output, and namely the control step motor is forward or counter-rotating operation.Send into D/A converter from each phase data signal of ring distributor output, the analog voltage signal after conversion is as the reference voltage of constant current chopper circuit.The constant current chopper circuit modulates corresponding pulse width signal and exports to the promotion level.
The driving stage circuit directly is connected with each phase winding of stepper motor, and it accepts to control conducting and the cut-off of each phase winding of motor from the signal that promotes level, and simultaneously, the voltage and current that also winding is born is controlled.stepping motor is a kind of motor that electric impulse signal is converted to the respective corners displacement of controlling with electric pulse, its operation needs special driving power, the pulse signal that the output of driving power is inputted is controlled, each pulse signal can make fixing angle of stepping motor rotation, this angle is called step angle, the existence of this linear relationship, add stepper motor to only have periodic error and without characteristics such as accumulated errors, the quantity of pulse has determined the total angle of rotation, the frequency of pulse has determined the speed of motor rotation, the power-up sequence that changes winding can change the direction of motor rotation, the pulse number that its rotational angle is sent out to some extent determines.
Pulse signal is produced by single chip computer AT 89C52 chip, by driving, pulse signal is passed to stepper motor, 51 single-chip computer control systems are necessarily spent according to the every 1 minor clock rotation of sequential procedure accurately, and the stairstep signal that converts thereof into stepper motor is exported control signal to stepper motor with signal by driver; Above-mentioned travel switch and stop block are used for showing of control device and final state.
The speed of the running of stepper motor determines by the frequency of driving pulse, and the pulse number that its rotational angle is sent out to some extent determines.Pulse signal is produced by single chip computer AT 89C52 chip, by driving, pulse signal is passed to stepper motor, and step motor control system is made of main frame, signal conversion, microcontroller, drive circuit and stepper motor on the whole.In control procedure, send control command by main frame, by with the next micro-controller communications, produce pulse control signal according to the order of main frame, Driving Stepping Motor turns round.The order of sending according to main frame is different, and stepper motor can be done respectively forward, counter-rotating, microrunning, fast turn-around and the action such as stop.
The signal power of single-chip microcomputer output is generally smaller, direct Driving Stepping Motor, and this completes power amplification with regard to the demand motive circuit, makes control wave satisfy the requirement of Driving Stepping Motor.
