Wherein, in the present embodiment, motor 14 is under the control of central processing unit 13, and for driving curtain to carry out folding and provide power, its power generally direct or indirectly-acting, in driving wheel 12, rotates to make driving wheel 12.Rotating speed passes rotation direction and the velocity of rotation that sensor 11 can detect driving wheel 12, this rotation direction refers to that driving wheel 12 carries out the state rotating forward or reverse, velocity of rotation refers to the speed of driving wheel 12 around its drive shaft turns, be commonly defined as the number of turns of rotating in the unit interval, also can be angular speed (also can be linear velocity when driving wheel 12 radius is known), this speed probe 11 can be realized by Hall current speed probe, the curent change that causes when rotating by measuring driving wheel 12 thus obtain rotation direction and velocity of rotation.
Drive circuit 15 is electrically connected with central processing unit 13 and motor 14 respectively, carry out work carry out rotating forward or reversing to drive above-mentioned driving wheel 12 for controlling motor 14 under the control of central processing unit 13, thus control curtain respectively and carry out closed to open or closed.Drive circuit 15 comprises rotating forward drive circuit 151 and reversing drive circuit 152, each drive circuit is connected between motor 14 and central processing unit 13, and central processing unit 13 can control to rotate forward drive circuit 151 and reversing drive circuit 152 respectively and control driving wheel 12 by motor 14 and carry out rotating forward and reversing.
Central processing unit 13, be electrically connected with speed probe 11, can judge whether the velocity of rotation that speed probe 11 detects is greater than preset value, and whether the rotation judging driving wheel 12 when this velocity of rotation is greater than preset value further causes for the driving of motor 14, also for driving wheel 12 rotation not for the driving of motor 14 cause time, control motor 14 starts work and is rotated further according to rotation direction originally to drive this driving wheel 12, and control motor 14 when being less than preset value for this velocity of rotation and quit work (if motor 14 itself quits work, then keep its out-of-work state).
With reference to figure 3, it is the functional block diagram of central processing unit 13 in Fig. 2.This central processing unit 13 comprise for judge velocity of rotation that speed probe 11 detects whether be greater than preset value the first judge module 131, for judge driving wheel 12 rotation whether for the driving of motor 14 cause the second judge module 132, for controlling out-of-work first Executive Module 134 of motor 14, starting for controlling motor 14 the second Executive Module 133 that work is rotated further according to the rotation direction that speed probe detects to drive this driving wheel 12.The result judged when the first judge module is yes, then the second judge module work, if judged result is no, then and the first Executive Module work.When the result that the second judge module judges is no, the second Executive Module work.In another embodiment, central processing unit 13 also can comprise the 3rd Executive Module 135 for keeping motor 14 script rotation direction, when the result that the second judge module judges is as being, the 3rd Executive Module 135 works, and now motor 14 is in normal operating condition.Wherein the first judge module 131 is electrically connected with speed probe 11, and the first Executive Module 134, second judge module 132, the 3rd Executive Module 135 are all electrically connected with drive circuit 15.
As: curtain is being opened or in closing process, the speed of driving wheel is 3 circles/second, preset value is 1 circle/second, for when people gets up the curtain seeing full cut-off morning, go to direction that curtain remote holder trend opens curtain to pull and loose one's grip after curtain, in this process, speed probe 11 detects that driving wheel 12 rotates forward, suppose to detect people pull curtain after speed be greater than 1 circle/second (the present embodiment speed average speed that to be instantaneous velocity also can be in a period of time), then central processing unit 13 controls curtain and continues to open, even if people still can continue motion after loosing one's grip.After curtain runs to standard-sized sheet, now driving wheel 12 cannot send and continue motion, and the velocity of rotation of its driving wheel 12 reduces to be even 0 gradually, and when speed probe 11 detects that speed is less than or equal to 1 circle/second, central processing unit 13 can control motor 14 and cut out.If curtain runs to midway, when user wants it to stop, user's manual pull is once loosed one's grip after curtain, now due to user manually pull curtain the velocity of rotation of driving wheel 12 also can be caused to reduce gradually is even 0, when speed probe 11 detects that speed is 1 circle/second, central processing unit 13 now also can control motor 14 and cut out.
With reference to figure 4, to be followingly described further the above-mentioned blind system being used for perception human body intention by composition graphs 4, wherein Fig. 3 is the control method of blind system in Fig. 2 of the present utility model, and the concrete steps of the method are as follows.
S1, speed probe 11 detect and move to drive curtain to carry out rotation direction and the velocity of rotation of the driving wheel 12 of folding for driving conveyer belt to carry out.After working on power, speed probe 11 detects rotation direction and the velocity of rotation of driving wheel, and the result detected 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, then perform step S3, and if not, then central processing unit control motor 14 quits work.Central processing unit 13 obtains the testing result that speed probe 11 sends, and carries out analysis judgement to this result.Wherein, if when speed probe 11 detects that rotation is less than or equal to preset value, illustrate that the rotating speed of driving wheel is very slow, now possible situation is: 1, curtain is in the effect of motor 14, standard-sized sheet or full cut-off, curtain cannot continue motion, and now the impulsive force of conveyer belt can act on driving wheel 12, is rotated further according to rotation direction originally to stop this driving wheel 12; 2, curtain not only non-standard-sized sheet but also be patent, but after running to the centre of the two, people's pulling curtain, now the impulsive force of conveyer belt also can act on driving wheel 12, is rotated further according to rotation direction originally to stop this driving wheel 12.Therefore, in both cases, then central processing unit 13 all can control motor 14 and quits work, and now curtain is parked in current location.Wherein, if when speed probe 11 detects that velocity of rotation is greater than the second preset value, illustrate that the rotating speed of driving wheel 12 is comparatively rapid, now, possible situation is: a, motor are running well, now curtain both non-standard-sized sheet also non-full cut-offs, and people does not also pull curtain simultaneously; B, motor itself do not work, and now curtain is undertaken closed by artificial operation or opens.In a, b two kinds of situations, central processing unit 13 needs to control motor 14 and takes different schemes, therefore needs further to be judged as which kind of situation.Wherein, in a, the scheme that this enforcement is taked is, central processing unit 13 controls the duty of motor 14, driving wheel 12 is made to keep original rotation direction and velocity of rotation to work on, in this step, central processing unit 13 can transmit operation instruction control speed and the direction of motor 14, also can no longer transmit operation instruction make motor keep original state in real time.In other embodiments, central processing unit 13 duty that can also control motor is to accelerate or the velocity of rotation of the driving wheel 12 that slows down.
Whether the rotation that S3, central processing unit 13 judge described driving wheel 12 causes for the driving of motor 14, if not, then performs step S4.Whether this step is for distinguishing above-mentioned a and b two kinds of situations, in this step, be that motor 14 causes described in judgement.According to whether sending to drive circuit 15 control instruction to carry out rotating with drive motors 14, central processing unit 13 learns that to be whether the driving of motor 14 cause.Because motor 14 runs under the control of central processing unit 13, whether need of work central processing unit 13 sending controling instruction of motor 14, when the control instruction sent works for controlling motor 14, then be illustrated as that motor causes, when send control instruction be control motor 14 close or do not send the instruction of any switching motor time, then illustrate behaviour pull curtain to cause.
S4, central processing unit 13 control motor 14 and start work and be rotated further according to described rotation direction to drive described driving wheel 12.After determining in step s3 not cause described in motor, so the rotation of moving runner 12 is just for human body pulls curtain to cause.Because now motor 14 does not work, so can control motor 14 and start work by central processing unit 13, driving wheel 12 is rotated further according to driving wheel 12 rotation direction originally, and therefore curtain can pull the direction of curtain to continue motion according to human body after people pulls curtain.Wherein, this step S4 comprises: central processing unit 13 judges that the rotation direction of the script of driving wheel 12 is as rotating forward or reversion, if rotate forward, then controlling to rotate forward drive circuit 151 drives described driving wheel 12 to carry out rotating forward to open curtain, if reversion, then control reversing drive circuit 152 and drive described driving wheel 12 to carry out reversing with closed curtain.
For above-described embodiment, when owner wants to open curtain, only curtain one need be drawn lightly toward the direction of opening, central processing unit 13 just can catch the rotating forward drive circuit 151 of this (rotating forward) action and starter motor 14 by speed probe 11, and curtain will be opened automatically.When curtain standard-sized sheet puts in place, or curtain is held (at this moment the rotating speed of motor 14 is even zero by obviously reducing) by owner lightly in curtain opening procedure, central processing unit 13 by speed probe 11 will perception owner want stop curtain action and rotating forward drive circuit 151 cuts out, motor 14 quits work immediately.In like manner: when owner wants to close curtain, only curtain one need be drawn lightly toward the direction closed, the reversing drive circuit 152 that speed probe 11 just can catch this (reversion) action and starter motor 14 crossed by central processing unit 13, and curtain will be closed automatically.When curtain complete shut-down puts in place, or curtain is held (at this moment the rotating speed of motor 14 is even zero by obviously reducing) by owner lightly in curtain closing process, central processing unit 13 crosses speed probe 11 and will perception owner want stop the action of curtain and cut out by reversing drive circuit 152, and motor 14 quits work immediately.
In practice process, in order to avoid the impact of motor 14 pairs of transmission mechanisms when curtain standard-sized sheet position, curtain complete shut-down position and owner hold curtain, it is as the reference stopped when being zero using rotating speed that central processing unit 13 has more than, but thinks that motor 14 cuts out as stop signal lower than during a certain value by rotating speed.Moreover: when curtain standard-sized sheet puts in place or complete shut-down puts in place, suitably motor 14 is run a bit of distance toward rightabout, 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 used for the structural representation of blind system second embodiment of perception human body intention for the utility model.In the first embodiment illustrated in fig. 1, because curtain is in running, when curtain standard-sized sheet or full cut-off, and people pulls suddenly curtain hourly velocity not identical, the rotating speed of driving wheel 12 is not identical yet, sometimes fast and sometimes slow even anxious the stopping of the rotating speed of motor is caused suddenly to open, be easy to cause the damage of drive mechanism especially motor 14 or driving wheel 12, therefore the present embodiment is also connected with a gearbox 17 and clutch 18 between driving wheel 12 and motor 14, wherein the output shaft of clutch 18 connects the power shaft of gearbox 17, the power shaft of clutch 18 connects the output shaft of motor 14, the output shaft of gearbox 17 connects the driving shaft of driving wheel.Gearbox 17 can be used in the conversion realizing velocity of rotation between motor 14 and driving wheel 12, velocities of rotation different between them can be adapted to and carry out the conversion of the different gear conversion proportion of driving wheel 12 angular speed (motor 14 with), clutch 18 between the power shaft and the output shaft of motor 14 of gearbox 17, for disconnecting or transmitting the power that motor 14 sends gearbox 17 to.When clutch 18 converts velocity of rotation between driving wheel 12 and motor 14, clutch 18 is in the state of "Off", the power of motor 14 is disconnected and passes to gearbox 17, and when motor 14 needs to drive this driving wheel 12 to rotate, clutch 18 is in the state of " conjunction ", by the power transmission of motor 14 to gearbox 17.Meanwhile, motor 14 do not work curtain be in static time, clutch 18 also belongs to the state of "Off", and when now people pulls curtain, external force can not act on motor 14, pulls curtain because reduce human body and damages drive mechanism.Wherein, speed probe 11 is directly installed on gearbox 17, by obtaining the duty of described gearbox 17 to obtain velocity of rotation and the rotation direction of the driving shaft 121 of driving wheel 12.
Therefore corresponding, in the system of the curtain for perception human body intention of this enforcement, in above-described embodiment step S1, speed probe 11 obtains that the velocity of rotation of driving wheel 12 and rotation direction also can be realized 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, for receiving the operational order that user sends, if user is by remote controller or mobile phone transmit operation instruction, this wireless communication unit 16 just can receive the operational order of mobile phone or remote control transmission.This wireless communication unit 16 comprise in mobile communication module (as 3G module, 4G module), bluetooth module, WIFI module one or more.User just can control curtain by transmit operation instruction and realize arbitrary aperture (degree that curtain is opened).Therefore, the step S5 of the curtain for perception human body intention of the present embodiment, this step also comprises:
S51, wireless communication unit 16 obtain the operational order that user sends.This wireless communication unit 16 is electrically connected with central processing unit 13.
S52, central processing unit 13 obtain this operational order from wireless communication unit 16, and the duty controlling motor 14 according to described operational order is to realize the control to the aperture of curtain.Therefore, central processing unit 13 also comprises the operation sent according to user and refers to that operational order controls the duty of motor 14 to realize control the 4th Executive Module to the aperture of curtain, and this module and drive circuit 15 are electrically connected.
In order to realize to curtain standard-sized sheet, full cut-off or and the control of other any opening degrees, before carrying out step S5, also comprise: S50, central processing unit 13 control motor 14 rotation and make curtain run to full cut-off from standard-sized sheet or run to standard-sized sheet from full cut-off, and are obtained the number of total coils N0 of driving wheel 14 rotation by speed probe 11 simultaneously.This process covers to obtain curtain the number of total coils N0 that in a stroke, driving wheel 11 rotates, and general number of total coils N0 only need obtain once, preserves to use next time after obtaining.Above-mentioned step S5 also comprises:
S53a, central processing unit 13 obtain the current aperture N1% of curtain and the appointment aperture N2% of operational order.Because central processing unit 13 can obtain the rotation number of turns of driving wheel 12 by speed probe 11, therefore just the number of turns/number of total coils N0 can be rotated by driving wheel 12, just can know the aperture of curtain, during as installed curtain or using, curtain is opened (aperture 100%), when driving wheel 12 rotates forward n circle, then aperture is that n/N0 is (if aperture is greater than 100%, then deduct a maximum integer, make aperture 0≤aperture≤100%), m circle (m≤n) if driving wheel 12 reverses again, then aperture is (n-m)/N0.
S54a, central processing unit 13 judge according to described current aperture N1% and described appointment aperture N2% the direction that curtain motor 14 needs to rotate and calculate the number of turns needing to rotate | N1%-N2%| × N0, wherein, if N1 > is N2, then perform step S55a, if N1 < is N2, then perform step S56a.
S55a, central processing unit 13 control motor 14 and reverse from current location, and the number of turns of electric machine rotation is: (N1%-N2%) × N0.
S56a, central processing unit 13 control motor 14 and rotate forward from current location, and the number of turns of electric machine rotation is (N2%-N1%) × N0.
Therefore, just curtain can be moved to the position of specifying corresponding to aperture N2% from current location by above-mentioned steps, the number of turns of this kind of mode driving wheel rotation is less, effectively can save the time that curtain reaches instruction aperture correspondence position.But, this kind of mode is adopted to control curtain, once run into power failure, central processing unit 13 can record the aperture of current curtain, before again sending a telegram here, when user's manual pull curtain, because speed probe 11 and central processing unit 13 quit work, central processing unit 13 record aperture be still power failure before data instead of people pull curtain after data, therefore next user by Long-distance Control time, curtain can't arrive the position of instruction.Therefore, after each power failure, user needs manually to operate, and arranges corresponding reset function on the cpu 13, curtain is manually drawn to standard-sized sheet or full cut-off (be 0% or 100% according to resetting to aperture during reset function) and determines by user, serves.
In other embodiments, above-mentioned step S5 can also be realized by following step:
S53b, central processing unit 13 obtain the appointment aperture N2% comprised in operational order.
The duty that S54b, central processing unit 13 control motor 14 makes curtain full cut-off, control motor 14 again and rotate forward N2% × N0 circle, or the duty that central processing unit 13 controls motor 14 makes curtain standard-sized sheet, then control motor reversal (1-N2%) × N0 circle.In the present embodiment, when receiving the operational order that user sends, central processing unit 13 first controls motor 14 to carry out rotating forward or reverse to make curtain standard-sized sheet or full cut-off, then position curtain being moved to specify at every turn.If have a power failure, after user pulls curtain, the data before central processing unit 13 still records.In the present embodiment, when again sending a telegram here, when the long-range transmit operation instruction of user makes curtain run to instruction aperture, motor 14 is first made to carry out rotating forward or reversing, when by speed probe 11, central processing unit 13 detects that the speed of driving wheel 12 obviously reduces (when being less than a preset value), then judge curtain standard-sized sheet or full cut-off, now again according to curtain be full cut-off or standard-sized sheet make motor run N2% × N0 or (1-N2%) × N0 enclose.In this kind of mode, even if having a power failure, user still can the long-range aperture to curtain control accurately.
