Description

The stepper motor controller that is used for the solar energy equipment automatic tracking system
Technical field
The utility model relates to a kind of stepper motor controller that is used for the solar energy equipment automatic tracking system.
Background technology
Solar energy is primary energy as clean energy resource, is again that regenerative resource has the incomparable superiority of fossil energy and widely used.
Because the rotation of the earth, each ground surface every day is different at the solar energy that different time absorbed on the earth, has only the solar energy maximum of accepting when vertical with sunlight.The sun rises every day eastwardly, noon is to the extreme higher position of sky, fall to the west then.If the direction of solar collector or solar cell immobilizes, alter a great deal in Various Seasonal, the different incidence angle that shines the sunray on solar collector or the solar cell constantly so, directly have influence on its receiving efficiency.
The cost of solar collector or solar cell is higher at present, and required solar collector of system or solar cell often much just can be satisfied the demand again.The efficient of solar energy collecting must not become irrespective factor, needs to adopt solar tracking system; The automatic tracking system that drives as power with motor is best, but often required motor is a lot of in system; The weight of solar collector or solar cell is bigger, and the control power of motor that solar tracking system requires is very big, and the power consumption total amount of control motor will be very big, influence its practical application in solar energy collector system or solar cell system.
Summary of the invention
The purpose of this utility model provide a kind of be convenient to comprehensive adjusting, and suitable carrying out between the stepper motor controller that is used for the solar energy equipment automatic tracking system of exhausting property control, thereby can improve the efficient that solar energy equipment receives solar energy.
The purpose of this utility model can realize by following technical measures:
A kind of stepper motor controller that is used for the solar energy equipment automatic tracking system, it comprises:
One power control circuit is used for regularly exporting required power supply signal, the switching of control power supply signal;
One clock signal circuit links to each other with the output of described power control circuit, is used to provide the forward and backward control signal;
One ON-OFF control circuit links to each other with the output of described clock signal circuit, be used for output control pulse and will receive just or reverse control signal as driving pulse;
One drive circuit links to each other with the output of described ON-OFF control circuit, is used to drive the stepper motor forward or reverse.
The utility model is reasonable in design, and is simple in structure, and control is sensitive reliable, utilizes it can make the solar energy equipment automatic tracking system along with sun east rises the variation that the west falls, and at every moment keeps vertical with sunlight, improves the efficient that solar energy equipment receives solar energy.

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of stepper motor controller that is used for the solar energy equipment automatic tracking system, power control circuit is by timing clock IC 1, triode BG 1, relay J 1, the three-terminal voltage-stabilizing ic chip 2Form.Timing clock IC 1When signal output is arranged, triode BG 1Conducting, relay J 1Must be electric, its normally opened contact J 1～1, J 1～2Adhesive, the three-terminal voltage-stabilizing ic chip 2Energized, output DC source V DD
The clock signal circuit links to each other with the output of described power control circuit, by the ic chip of counting band oscillator 3Form signal generator with crystal oscillator 32768, the ic chip of counting band oscillator 3One output is through the level Four counting of decimal system count splitter 4017, and providing with door 4081 through four or two inputs more just changes control signal F 1, another output directly provides reverse control signal F 2
ON-OFF control circuit links to each other with the output of clock signal circuit, by relay J 2, J 3, manually just changeing push switch K 1, the manual push switch K that reverses 2, manual stall push switch K 3, just change limit switch K 4, counter-rotating limit switch K 5Form.As just changeing control signal F 1The time, relay J 2, J 3Be normality, DIR is a high level, output driving pulse PUL (just changeing pulse); As reverse control signal F 2The time, relay J 2, J 3Be adhesive, DIR is a low level, output driving pulse PUL (inversion pulse).
Drive circuit links to each other with the output of ON-OFF control circuit, by four bidirectional switch integrated packages 4060, six reversers 4009 and triode BG 2, BG 3Form.When DIR is that high level, PUL make BG 2The L of conducting, stepper motor AElectricity is arranged, because capacitance discharges makes the L of stepper motor BThen energising, the motor positive direction is rotated; When DIR is low level, PUL makes BG 3Conducting, L BElectricity is arranged, because capacitance discharges makes L earlier AThen energising, the motor counter-rotation.
Concrete operation principle is as follows:
Controller is in wait state during beginning, as timing clock IC 1To the time of setting, export a high level, make triode BG 1Conducting, J 1Adhesive, self-locking contact J 1-1, J 1-2Connect the three-terminal voltage-stabilizing ic chip 2There is power supply signal output that controller is started working.
The clock signal circuit get electric after, producing is simultaneously just changeing control signal F 1With reverse control signal F 2, owing to the relay J of ON-OFF control circuit this moment 2, J 3Be in the normal state, driving pulse PUL is just being changeed in ON-OFF control circuit output, and control impuls DIR is a high level, and the motor positive direction is rotated, and the solar energy equipment automatic tracking system is changeed from east to west, meets limit switch K 4The time, make relay J 2Adhesive, ON-OFF control circuit output inversion driving pulse PUL, control impuls DIR is a low level, the motor counter-rotation is changeed the solar energy equipment automatic tracking system from west to east, meets limit switch K 5The time make relay J 3Adhesive J 1By short circuit, J 1Return normality, J 1-1And J 1-2Disconnect the whole driving part outage of maintenance, make controller be in wait state.
Second day when arriving setting-up time, timing clock IC 1Export a high level again, controller is started working again.
For the ease of the people detection system, need manually control the motor forward and backward, so in automatic control system, be provided with manual control push switch specially.Press K 1Motor just changes fast; Press K 2Make J 2Adhesive, the motor counter-rotating; Press K 3No PUL pulse is exported and is shut down.
