In another embodiment, central processing unit 13 can also comprise for keepingMotor 14 the 3rd Executive Module 135 of rotation direction originally, the result judging when the second judge module is yesTime, the 3rd Executive Module 135 is worked, and now motor 14 is in normal operating condition. Wherein the first judgementModule 131 is electrically connected with speed probe 11, the first Executive Module 134, the second judge module 132,The 3rd Executive Module 135 is all electrically connected with drive circuit 15.
As: curtain open or closing process in the speed of driving wheel be 3 circle/seconds, preset value be 1 circle/Second, while seeing the curtain of full cut-off for getting up morning as people, go to curtain remote holder trend and open the direction of curtainPull and loose one's grip after curtain, in this process, speed probe 11 detects driving wheel 12 forwards, supposesDetect and people pull speed after curtain to be greater than for 1 circle/second (the present embodiment speed is that instantaneous velocity can be alsoAverage speed in a period of time), central processing unit 13 is controlled curtain and is continued to open, even if people looses one's gripRear still can continuation moves. When curtain runs to after standard-sized sheet, now driving wheel 12 cannot continue motion, itsIt is even 0 that the velocity of rotation of driving wheel 12 reduces gradually, when speed probe 11 detects that speed is less thanIn the time of 1 circle/second, central processing unit 13 can control motor 14 and cut out. If curtain runs to midway, userWhile wanting it to stop, user manually pulls and looses one's grip after curtain, now because user manually pulls curtainThe velocity of rotation that also can cause driving wheel 12 to reduce be gradually even 0, when speed probe 11 detectsWhen speed was 1 circle/second, central processing unit 13 now also can control motor 14 and cut out.
With reference to figure 4, followingly in connection with Fig. 4, the above-mentioned blind system for perception human body intention is done into oneStep explanation, wherein Fig. 3 is the control method of blind system in Fig. 2 of the present invention, the concrete steps of the methodAs follows.
S1, speed probe 11 detects for driving conveyer belt to move to drive curtain to carry out foldingThe rotation direction of driving wheel 12 and velocity of rotation. After working on power, speed probe 11 detects driving wheelRotation direction and velocity of rotation, and the result detecting is sent to central processing unit 13.
S2, central processing unit 13 judge whether above-mentioned velocity of rotation is greater than preset value, if so, carry out stepRapid S3, if not, central processing unit control motor 14 quits work. Central processing unit 13 obtains rotating speedThe testing result that sensor 11 sends, and this result is analyzed to judgement. Wherein, if speed probe11 detect when rotation is less than or equal to preset value, illustrate that the rotating speed of driving wheel is very slow, now possibleSituation is: 1, curtain is in the effect of motor 14, standard-sized sheet or full cut-off, and curtain cannot continueMotion, now the impulsive force of conveyer belt can act on driving wheel 12, to stop this driving wheel 12 according to originallyRotation direction be rotated further; 2, not only standard-sized sheet but also be patent not of curtain, but run to the centre of the twoAfter, people's pulling curtain, now the impulsive force of conveyer belt also can act on driving wheel 12, to stop this to driveDriving wheel 12 is rotated further according to rotation direction originally. Therefore, in both cases, central authorities processDevice 13 all can be controlled motor 14 and quit work, and now curtain is parked in current location. Wherein, if revolution speed sensingDevice 11 detects when velocity of rotation is greater than the second preset value, illustrates that the rotating speed of driving wheel 12 is comparatively rapid, thisTime, possible situation is: a, motor are running well, now both also full cut-offs not of standard-sized sheet not of curtain, simultaneouslyPeople does not also pull curtain; B, motor itself are not worked, and now curtain is closed by artificial operationClose or open. In a, two kinds of situations of b, central processing unit 13 need to be controlled motor 14 and take differenceScheme, therefore need to be further judged as which kind of situation. Wherein, in a, this enforcement is takedScheme be that central processing unit 13 is controlled the duty of motor 14, makes driving wheel 12 keep originalRotation direction and velocity of rotation work on, in this step, central processing unit 13 can refer in transmit operationSpeed and the direction of motor 14 controlled in order in real time, and also no longer transmit operation instruction makes motor keep formerSome states. In other embodiments, the duty that central processing unit 13 can also be controlled motor is to addThe velocity of rotation of the fast or driving wheel 12 that slows down.
S3, central processing unit 13 judge that the rotation of described driving wheel 12 is whether by the driving of motor 14 is madeBecome, if not, perform step S4. This step is for distinguishing two kinds of situations of above-mentioned a and b, thisIn step, described in judging, whether be that motor 14 causes. Whether central processing unit 13 is according to sending to driving electricWhether road 15 control instructions are rotated and are learnt as the driving of motor 14 and cause taking drive motors 14. ByTo move under the control of central processing unit 13 in motor 14, the whether need of work centre of motor 14Reason device 13 sending controling instructions, in the time that the control instruction sending is worked for controlling motor 14, are illustrated as electricityMachine causes, when the control instruction sending is to control motor 14 to close or do not send any switch motorWhen instruction, explanation is behaved and is pulled curtain to cause.
S4, central processing unit 13 are controlled motor 14 startup work to drive described driving wheel 12 according to describedRotation direction is rotated further. After causing described in definite not motor in step S3, moving runner so12 rotation just causes for human body pulls curtain. Because motor 14 is not now worked, so can inCentral processor 13 is controlled motor 14 startup work, makes driving wheel 12 according to driving wheel 12 rotation originallyDirection is rotated further, and therefore curtain can pull the direction of curtain to continue fortune according to human body after people pulls curtainMoving. Wherein, this step S4 comprises: central processing unit 13 judges the rotation direction of the script of driving wheel 12For forward is still reversed, if forward is controlled forward drive circuit 151 and driven described driving wheel 12 to enterRow forward is to open curtain, if reversion is controlled reversing drive circuit 152 and driven described driving wheel 12Reverse with closed curtain.
For above-described embodiment, in the time that owner wants to open curtain, only need be by curtain toward the direction of opening gentlyGround one draws, and central processing unit 13 just can catch this (forward) action by speed probe 11 and openThe forward drive circuit 151 of moving motor 14, curtain will be opened automatically. In the time that curtain standard-sized sheet puts in place, orIn curtain opening procedure, owner holds curtain that (at this moment the rotating speed of motor 14 will obviously reduce even lightlyBe zero), central processing unit 13 by speed probe 11 will perception owner want to stop curtain action andForward drive circuit 151 cuts out, and motor 14 quits work immediately. In like manner: when owner wants to close curtainTime, only curtain one need be drawn lightly toward the direction of closing, central processing unit 13 is just crossed speed probe 11Can catch this (reversion) action and the reversing drive circuit 152 of starter motor 14, curtain will be automaticallyClose. In the time that curtain complete shut-down puts in place, or in curtain closing process, (at this moment owner holds curtain lightlyIt is even zero that the rotating speed of motor 14 will obviously reduce), central processing unit 13 is crossed speed probe 11 willPerception owner wants to stop the action of curtain and reversing drive circuit 152 is closed, and motor 14 stops work immediatelyDo.
In practice process, for fear of holding curtain curtain standard-sized sheet position, curtain complete shut-down position and ownerTime the impact of motor 14 to transmission mechanism, central processing unit 13 have more than be using rotating speed be 1 o'clock as stoppingReference, but think and as stop signal, motor 14 cut out when rotating speed is lower than a certain value. AgainPerson: when curtain standard-sized sheet puts in place or complete shut-down puts in place, suitably that motor 14 is a bit of toward rightabout operationDistance, this is also the fabulous way of protection transmission mechanism (motor 14, driving-belt, driving wheel 12 etc.).
With reference to figure 5, it is for the present invention is for the structure of blind system second embodiment of perception human body intentionSchematic diagram. In the first embodiment illustrated in fig. 1, due to curtain in running, curtain standard-sized sheetOr speed is not identical when full cut-off and when people pulls curtain suddenly, also phase not of the rotating speed of driving wheel 12With, sometimes fast and sometimes slow even anxious anxious the opening of stopping of rotating speed that causes motor, is easy to cause especially electricity of drive mechanismThe damage of machine 14 or driving wheel 12, therefore the present embodiment is also connected between driving wheel 12 and motor 14Have a gearbox 17 and clutch 18, wherein the output shaft of clutch 18 connects the input of gearbox 17Axle, the power shaft of clutch 18 connects the output shaft of motor 14, and the output shaft of gearbox 17 connects drivingThe driving shaft of wheel. Gearbox 17 can be used in the change that realizes velocity of rotation between motor 14 and driving wheel 12Change, can adapt to velocities of rotation different between them and carry out different gears (motor 14 and driving wheel 12The conversion proportion of angular speed) conversion, clutch 18 is positioned at the power shaft of gearbox 17 and motor 14Between output shaft, for disconnecting or transmit motor 14 and send to the power of gearbox 17. Clutch 18Convert velocity of rotation between driving wheel 12 and motor 14 time, clutch 18 in " from " state,Make the power disconnection of motor 14 pass to gearbox 17, and enter at this driving wheel 12 of motor 14 demand motivesWhen row rotates, the state of clutch 18 in " closing ", passes to gearbox by the power of motor 1417. Meanwhile, do not work curtain when static at motor 14, clutch 18 also belong to " from " shapeState, when now people pulls curtain, external force can not act on motor 14, because minimizing human body pulls curtainDamage drive mechanism. Wherein, speed probe 11 is directly installed on gearbox 17, described in obtainingThe duty of gearbox 17 is to obtain velocity of rotation and the rotation side of driving shaft 121 of driving wheel 12To.
Therefore corresponding, in the system of the curtain for perception human body intention of this enforcement, above-mentioned enforcementIn example step S1, velocity of rotation and rotation direction that speed probe 11 obtains driving wheel 12 are also passableRealize by the duty by obtaining described gearbox 17.
In order to realize the remote control of people to this system, this system can comprise a wireless communication unit 16,This communication unit 16 is electrically connected with central processing unit 13, the operational order sending for receiving user, asUser is by remote controller or mobile phone transmit operation instruction, and this wireless communication unit 16 just can receive mobile phoneOr the operational order that remote control sends. This wireless communication unit 16 comprises mobile communication module (as 3G mouldPiece, 4G module), one or more in bluetooth module, WIFI module. User is by transmit operationInstruction just can be controlled curtain and realize aperture (degree that curtain is opened) arbitrarily. Therefore, the present embodimentThe step S5 of the curtain being intended to for perception human body, this step also comprises:
S51, wireless communication unit 16 obtain the operational order that user sends. This wireless communication unit 16 withCentral processing unit 13 is electrically connected.
S52, central processing unit 13 obtain this operational order from wireless communication unit 16, and according to described behaviourMake the duty of instruction control motor 14 to realize the control of the aperture to curtain. Therefore, centreReason device 13 also comprises that the duty that refers to operational order control motor 14 according to the operation of user's transmission is to realizeThe control of the aperture to curtain the 4th Executive Module, this module and drive circuit 15 are electrically connected.
For realize to curtain standard-sized sheet, full cut-off or and the control of other any opening degrees, carry out step S5 itBefore, also comprise: S50, central processing unit 13 are controlled motor 14 rotations curtain is run to from standard-sized sheet entirelyClose or run to standard-sized sheet from full cut-off, and obtaining by speed probe 11 total that driving wheel 12 rotates simultaneouslyNumber of turns N0. This process is to cover in order to obtain curtain total circle that in a stroke, driving wheel 12 rotatesNumber N0, general number of total coils N0 only need obtain once, obtains rear preservation to use next time. Above-mentionedStep S5 also comprises:
S53a, central processing unit 13 obtain the appointment aperture of current aperture N1% and the operational order of curtainN2%. Because central processing unit 13 can obtain by speed probe 11 the rotation number of turns of driving wheel 12,Therefore just can rotate the number of turns/number of total coils N0 by driving wheel 12, just can know the aperture of curtain, asWhen curtain being installed or being used, curtain is opened to (aperture 100%), when driving wheel 12 forward n circles,Aperture be n/N0 (if aperture is greater than 100%, deduct a maximum integer, make aperture 0≤aperture≤100%), if driving wheel 12 reverses again m circle (m≤n), aperture is (n-m)/N0.
S54a, central processing unit 13 judge window according to described current aperture N1% and described appointment aperture N2%Curtain motor 14 needs the direction of rotating and calculates the number of turns that needs rotation | N1%-N2%| × N0, wherein,If N1 > is N2, perform step S55a, if N1 < is N2, perform step S56a.
S55a, central processing unit 13 are controlled motor 14 and are started reversion, the number of turns of electric machine rotation from current locationFor: (N1%-N2%) × N0.
S56a, central processing unit 13 are controlled motor 14 and are started forward from current location, the number of turns of electric machine rotationFor (N2%-N1%) × N0.
Therefore, just curtain can be moved to and specifies aperture N2% institute right from current location by above-mentioned stepsThe position of answering, the number of turns that this kind of mode driving wheel rotates is less, can effectively save curtain and reach instruction and openThe time of degree correspondence position. But, adopt this kind of mode control curtain, once run into power failure, centreReason device 13 can be recorded the aperture of current curtain, before again sending a telegram here, when user manually pulls curtainTime, because speed probe 11 and central processing unit 13 quit work, central processing unit 13 recordsData instead of people that aperture is still before having a power failure pull curtain data afterwards, therefore next userDuring by Long-distance Control, curtain can't arrive the position of instruction. Therefore,, after each power failure, useFamily all needs manually to operate, and on central processing unit 13, corresponding reset function is set, user's handMoving curtain is drawn to standard-sized sheet or full cut-off (according to reset function time reset to aperture be 0% or 100%)Determine, serve.
In other embodiments, above-mentioned step S5 can also realize by following step:
S53b, central processing unit 13 obtain the appointment aperture N2% comprising in operational order.
The duty that S54b, central processing unit 13 are controlled motor 14 makes curtain full cut-off, then controls motor14 forward N2% × N0 circle, or the duty that central processing unit 13 is controlled motor 14 makes curtain completeOpen, then control motor reversal (1-N2%) × N0 circle. In the present embodiment, receive user at every turn and sendOperational order time, central processing unit 13 is first controlled motor 14 and is carried out forward or reversion so that curtain standard-sized sheetOr full cut-off, then make curtain move to the position of appointment.
