Fig. 2 is a kind of structured flowchart of execution mode of the control device of tube shaped electric machine.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
As shown in Figure 1, the control method of tube shaped electric machine may further comprise the steps:
10. obtain the current number of turns and the default number of turns of motor;
The account form of the current number of turns is, the number of turns that turns over the positive veer of setting is for just, and the number of turns that the reverse directions of setting turns over adds up for negative, draws one and drag the corresponding absolute number of turns in each position of stroke.
The form of obtaining of the default number of turns can be the form of instruction or data, if when instruction drags certain position command in the stroke, increases the step that travel position is converted to the absolute number of turns before the step of obtaining the default number of turns.Position command can be brought more directly perceived and operating experience easily for the user.
The mode of obtaining can be to obtain by controller or network data; The input of network data can also be imported by interactive interface, and the user can drag stroke adjustment to motor intuitively like this, for example, observes and specify the height of automatic curtain lifting on display screen.Network data than other forms of data, benefit is not remote controlled scope of application restriction of user, can control motor by network.
The detection mode of the current number of turns has following two kinds: a kind of is to detect the number of turns that rotor changeed; Another kind is to detect the number of turns that the motor reducer output is changeed.Obviously, the former has higher control precision than the latter to Electric Machine Control.
20. judge the relation of this current number of turns and the described default number of turns, if the described current number of turns equals the described default number of turns, execution in step 30; If the described current number of turns is greater than the described default number of turns, execution in step 40; If the described current number of turns is less than the described default number of turns, execution in step 50.
30. send the signal that makes described motor stop;
40. generate the direction signs of counter-rotating, execution in step 61;
50. generate the direction signs of just changeing, execution in step 62.
60. adjust the described current number of turns, jump procedure 10 according to described direction signs.This step comprises:
61., trigger motor and carry out backward rotation, and on the basis of the described current number of turns, deduct the counter-rotational number of turns according to the direction signs of described counter-rotating.
62., trigger motor and carry out forward rotation, and on the basis of the described current number of turns, add the number of turns of forward rotation according to described direction signs of just changeing.
The control method of above-mentioned tube shaped electric machine mainly be with the incongruent current number of turns of the default number of turns, adjust according to the direction signs that calculate, meet until adjusting to the default number of turns; Thereby realized adjusting the folding degree of curtain automatically according to setting the number of turns.
The control device of tube shaped electric machine in the present embodiment, as shown in Figure 2, comprise: number of turns sensing module 100, number of turns memory module 200, number of turns comparison module 300, stopping modular 400, identification module 500, adjusting module 600, wherein have number of turns memory module 200, number of turns comparison module 300, stopping modular 400, identification module 500, adjusting module 600 at least, be integrated on the single-chip microcomputer.
Number of turns sensing module 100 is used to obtain the current number of turns of described motor; Described number of turns sensing module 100 can be arranged on described rotor side or be arranged on the motor reducer output, other to be arranged on rotor as preferred, because than being arranged on the motor reducer output, being arranged on the rotor side and having higher control precision; Described number of turns sensing module 100 can adopt at least two Hall elements or photoelectric cell.
Number of turns memory module 200 is used to store the default number of turns;
Number of turns comparison module 300 is connected with described number of turns sensing module 100 with this number of turns memory module 200, is used for relatively this current number of turns and the described default number of turns and generates comparative result
Stopping modular 400 is connected with number of turns comparison module 300, is used for equaling according to the current number of turns comparative result of the default number of turns, sends the signal that makes described motor stop.
Adjusting module 600 is connected with this number of turns comparison module, adjusts the current number of turns until equating with the described default number of turns according to these direction signs; Comprise the forward relay that the described motor of control is just changeing in the adjusting module 600 and control the negative-phase relay that described motor reverses.
Whether the control device of above-mentioned tube shaped electric machine starts by number of turns sensing module 100 and number of turns comparison module 300 control motors, direction by identification module 500 control motors rotations, thereby realized adjusting the folding degree of curtain automatically, improved the convenience and the practicality of remote-controlled curtain suspension according to setting the number of turns.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
