According to one embodiment of present invention, x Hall detection components 20 such as Hall element can use paster and plug-in unit Two kinds of packing forms of type, x Hall detection components 20 are each attached to PCB (Printed Circuit Board；Printed circuit board) It is fixed on plate and by pcb board in air conditioner main body, positioned at the side of magnet assembly 10, close to magnet assembly 10 but noncontact, Can be in induction range in magnetic field.

According to one embodiment of present invention, as shown in figures 8-13, multiple N magnetic poles of every layer of magnet assembly 10 and/or many Moving direction of the individual S magnetic poles along moving component is set.That is, magnet assembly 10 is securable on moving component, and side To vertical with the direction of motion of moving component.In other words, along the enabling/close the door of moving component moving direction such as door-plate 300 Interval is covered with multiple N magnetic poles and/or multiple S magnetic poles successively on direction, magnet assembly 10.

Thus, when every layer of interval of magnet assembly 10 is full of N magnetic poles and S magnetic poles, when moving component is moved, every layer of magnetic N magnetic poles and S magnetic poles on component 10 can be alternately through corresponding Hall detection components 20, and then make each Hall detection components 20 Produce corresponding induced signal.When every layer of interval of magnet assembly 10 is full of N magnetic poles and the first white space, moved in moving component When dynamic, N magnetic poles and the first white space on every layer of magnet assembly 10 can alternately through corresponding Hall detection components 20, and then Each Hall detection components 20 are made to produce corresponding induced signal.When every layer of interval of magnet assembly 10 is empty full of S magnetic poles and second During white region, when moving component is moved, S magnetic poles and the second white space on every layer of magnet assembly 10 can be alternately through corresponding Hall detection components 20, and then each Hall detection components 20 is produced corresponding induced signal.

According to one embodiment of present invention, as shown in Fig. 2-13, moving direction of the x layers of magnet assembly 10 in moving component On width it is equal, and the alignment of x layers of magnet assembly 10 sets.That is, x layers of magnet assembly 10 use same widths, from And x Hall detection components start simultaneously at detection and simultaneously detection of end.In other words, x Hall detection components can enter x simultaneously The initiating terminal of layer magnet assembly 10, and the end end of x layers of magnet assembly 10 is left simultaneously.

Further, according to Fig. 2-13 embodiment, x layers of magnet assembly 10 are along the moving direction perpendicular to moving component Direction it is setting up and down successively.That is, x layers of magnet assembly 10 can be set gradually from top to bottom on moving component, and not It is overlapping, for example, first layer magnet assembly, upper, second layer magnet assembly is under.

In addition, according to some embodiments of the present invention, as shown in Fig. 2,4,6,8,10 and 12, x layers of magnet assembly can be by x The magnet assembly of separation is combined.Or, as shown in Fig. 3,5,7,9,11 and 13, x layers of magnet assembly 10 can be wholely set, and Correspondence magnetic pole is in the x layers of pre-determined distance that staggers successively, by taking two layers of magnet assembly up and down as an example, and correspondence magnetic pole staggers pre- at two layers up and down If distance.

Further, according to one embodiment of present invention, as shown in Fig. 2-13, multiple N on every layer of magnet assembly 10 Magnetic pole and/or multiple S magnetic poles are set in wide mode.That is, when being distributed multiple N magnetic poles in the detection faces of magnet assembly 10 During with multiple S magnetic poles, the width of the width all same of the width all same of each N magnetic poles and each S magnetic poles is identical；Or work as magnetic When being spaced apart multiple N magnetic poles in the detection faces of property component 10, the first white space is distributed between two adjacent N magnetic poles； Or when being spaced apart multiple S magnetic poles in the detection faces of magnet assembly 10, second is distributed between two adjacent S magnetic poles empty White region.

It should be noted that the width of N magnetic poles and/or S magnetic poles is more narrow better on the premise of magnetic field intensity is ensured, such as 1-2 millimeters can be accomplished, magnetic field intensity is required depending on the hall sensing parameter according to Hall detection components 20.

Specifically, when on magnet assembly 10 interval be full of N magnetic poles and the first white space or S magnetic poles and the second clear area During domain, the magnetic regions width of N magnetic poles or S magnetic poles can be obtained according to below equation：

D1=(1+ (arcsin (X/A)+arcsin (Y/A))/π) * D/p/2,

Wherein, d1 is the magnetic regions width of N magnetic poles or S magnetic poles, and A is close for the maximum magnetic flux of N magnetic poles or S magnetic poles, and X is Hall The operating point of detection components, Y is the point of release of Hall detection components, and D is moving direction of the magnet assembly 10 along moving component Length, p is the number of N magnetic poles or S magnetic poles.

That is, the magnetic regions width of N magnetic poles can be set according to N pole numbers, or, can be according to S pole numbers The magnetic regions width of S magnetic poles is set.

Correspondingly, the width of the first white space or the second white space can be obtained according to below equation：

D2=D/p-d1.

Wherein, d2 is the width of the first white space or the second white space, and d1 is the magnetic regions of N magnetic poles or S magnetic poles Width, D is width of the magnet assembly 10 along the moving direction of moving component, and p is the number of N magnetic poles or S magnetic poles.

It is, the width of the first white space can be set according to the number of N magnetic poles and the magnetic regions width of N magnetic poles, Or the width of the second white space can be set according to the number of S magnetic poles and the magnetic regions width of S magnetic poles.

In addition, according to the specific example of the present invention, magnetic regions are the width and the first blank in N magnetic pole magnetics region The width in region also can approximately equal, or magnetic regions are the width in S magnetic pole magnetics region and the width of the second white space Also can approximately equal.That is, the width of the width of N magnetic poles and the first white space can be equal, the width of S magnetic poles and second The width of white space also can be equal, so as to simplify design, the manufacture difficulty of magnet assembly.

According to one embodiment of present invention, x Hall detection components 20 can match the magnetic of the magnetic pole on magnet assembly 10 Property set.For example, when interval is full of N magnetic poles and S magnetic poles on magnet assembly 10, x Hall detection components 20 can be ambipolar Hall element, ambipolar Hall element can be respectively induced N magnetic poles and S magnetic poles, different to be generated when sensing different magnetic poles Signal；And for example, when on magnet assembly 10 interval full of N magnetic poles and the first white space or full of S magnetic poles and the second blank During region, x Hall detection components 20 can be monopole type Hall element, and monopole type Hall element can sense the magnetic pole of matching, with Induced signal is generated in the magnetic pole of sensing matching, that is to say, that the type selecting of monopole type Hall element is matched somebody with somebody with monopole magnetism component Close, if monopole magnetism component is N polar forms, monopole type Hall also selects N polar forms, if monopole magnetism component is S polar forms, Monopole type Hall also selects S polar forms.

According to one embodiment of present invention, each Hall detection components 20 can generate phase according to the magnetic pole type sensed The induced signal answered.

For example, when being distributed multiple N magnetic poles and multiple S magnetic poles on magnet assembly 10, Hall corresponding with the magnet assembly Detection components 20 generate the first level when just to N magnetic poles, and generate second electrical level when just to S magnetic poles., wherein it is desired to illustrate , the first level can be high level and second electrical level can be low level, or the first level can be low level and second electrical level Can be high level, level state can specifically be determined according to the type of Hall detection components 20.

So, when N magnetic poles on magnet assembly 10 and S magnetic poles are alternately across corresponding Hall detection components 20, accordingly Hall detection components 20 will export stable low and high level pulse train, thus, the exportable x roads of x Hall detection components 20 The cycle of low and high level pulse train fixes and identical, dutycycle is 50%.

And for example, when being distributed multiple N magnetic poles on magnet assembly 10, Hall detection components 20 corresponding with the magnet assembly exist The first level is generated when just to N magnetic poles, and second electrical level is generated when just to the first white space.So, when magnet assembly 10 When upper N magnetic poles and the first white space are alternately across corresponding Hall detection components 20, corresponding Hall detection components 20 will be defeated Go out stable low and high level pulse train, thus, the week for the x roads low and high level pulse train that x Hall detection components 20 are exported Phase fixes and identical, dutycycle is 50%.

For another example, when being distributed multiple S magnetic poles on magnet assembly 10, Hall detection components 20 corresponding with the magnet assembly exist The first level is generated when just to S magnetic poles, and second electrical level is generated when just to the second white space.So, when every layer of magnetic group When S magnetic poles and the second white space are alternately across corresponding Hall detection components 20 on part 10, corresponding Hall detection components 20 Stable low and high level pulse train will be exported, thus, the x roads low and high level pulse train that x Hall detection components 20 are exported Cycle fix and identical, dutycycle be 50%.

Thus, the N magnetic poles and/or S magnetic poles on magnet assembly 10 can accomplish that very intensive (magnet pole widths can accomplish 1- 2mm), sensitivity is high, can improve the frequency of feedback pulse, so as to shorten detection time, improve detection sensitivity.And And, it is reliable and stable based on Hall effect, it is disturbed low, impulse waveform is stable, and low and high level saltus step is rapid.

According to one embodiment of present invention, predetermined angle is pre- including the first predetermined angle, the second predetermined angle and the 3rd If angle, when being distributed multiple N magnetic poles and multiple S magnetic poles in the detection faces of every layer of magnet assembly 10, the x layers of basis of magnet assembly 10 The number sum of N magnetic poles and S magnetic poles staggers the 3rd predetermined angle；When multiple N are distributed with the detection faces of every layer of magnet assembly 10 During magnetic pole, x layers of magnet assembly 10 stagger the first predetermined angle according to the number sum of N magnetic poles and the first white space；When every layer When multiple S magnetic poles are spaced apart in the detection faces of magnet assembly 10, x layers of magnet assembly 10 are according to S magnetic poles and the second white space Number sum stagger the second predetermined angle.

That is, x layers of magnet assembly 10 can stagger arrangement distribution, and x layers of magnet assembly 10 can match the magnetic of magnet assembly 10 Pole width staggers pre-determined distance, the preset phase so that the x road feel induction signals that x Hall detection components 20 are exported respectively stagger successively Angle, so that, detection sensitivity is lifted at double.

As shown in Fig. 2-13, by taking two layers of magnet assembly 10 as an example, upper strata magnet assembly 10A and lower floor magnet assembly 10B are equal Using identical arrangement mode, stagger pre- between the magnetic pole of upper strata magnet assembly 10A and lower floor magnet assembly 10B same magnetic If distance, that is to say, that as shown in Fig. 2-3 and Fig. 8-9, lower floor magnet assembly 10B each N magnetic poles are relative to upper strata magnetic group Part 10A corresponding N magnetic poles stagger pre-determined distance, and lower floor magnet assembly 10B each S magnetic poles are relative to upper strata magnet assembly 10A corresponding S magnetic poles stagger pre-determined distance.As shown in Fig. 4-5 and Figure 10-11, lower floor magnet assembly 10B each N magnetic poles Corresponding N magnetic poles relative to upper strata magnet assembly 10A stagger pre-determined distance, lower floor magnet assembly 10B each white space Corresponding white space relative to upper strata magnet assembly 10A staggers pre-determined distance.As shown in Fig. 6-7 and Figure 12-13, lower floor's magnetic Property component 10B corresponding S magnetic pole of each S magnetic poles relative to upper strata magnet assembly 10A staggers pre-determined distance, lower floor's magnetic group Part 10B each white space staggers pre-determined distance relative to upper strata magnet assembly 10A corresponding white space.

By taking opening direction movement of the x layers of magnet assembly 10 into Fig. 3 shown in arrow as an example, lower floor magnet assembly 10B correspondences Hall detection components 20B output the corresponding Hall detection components 20A of the delayed upper strata magnet assembly 10B of induced signal preset phase Parallactic angle.

Specifically, the first pre-determined distance or the second predetermined angle, or the 3rd predetermined angle can be determined according to below equation：

D=s/x

Wherein, d is the first pre-determined distance or the second predetermined angle, or the 3rd predetermined angle, s is each N magnetic poles or S magnetic poles Magnet pole widths, x be magnet assembly 10 the number of plies.

It should be noted that when being intervally distributed with multiple N magnetic poles and multiple S magnetic poles on every layer of magnet assembly 10, N magnetic poles Equal with the magnet pole widths of S magnetic poles, the magnet pole widths of each N magnetic poles or S magnetic poles can be equal to magnet assembly 10 along moving component The ratio between total number p of width D and N magnetic poles and S magnetic poles on moving direction, i.e. s=D/p；When interval on every layer of magnet assembly 10 When multiple N magnetic poles are distributed with, the magnet pole widths of each N magnetic poles may approximately equal to magnet assembly 10 along along the moving direction of moving component Width D and N magnetic poles and the first white space the ratio between total number p, i.e. s=D/p；It is spaced apart when on every layer of magnet assembly 10 When having multiple S magnetic poles, the magnet pole widths of each S magnetic poles may approximately equal to magnet assembly 10 along the width on the moving direction of moving component Spend the ratio between D and total number p of S magnetic poles and white space, i.e. s=D/p.

That is, can also determine pre-determined distance, i.e. d=D/p/x according to below equation.

Specifically, by taking the number of plies x=2 of magnet assembly 10 as an example, the corresponding magnetic pole of two layers of magnet assembly staggers s/ up and down 2, it is assumed that multiple N magnetic poles and multiple S magnetic poles are intervally distributed with every layer of magnet assembly 10, the width D of each magnet assembly 10 is The total number p of 15mm, N magnetic pole and S magnetic poles be 15, then pre-determined distance can obtain d=D/p/x=15/15/2=0.5mm, i.e., on The corresponding magnetic pole of lower two layers of magnet assembly staggers 0.5mm.More specifically, as shown in figures 8-13, lower floor magnet assembly 10B relative to Upper strata magnet assembly 10A staggers s/2 such as 0.5mm, and on upper strata, the corresponding Hall detection components 20A of magnet assembly 10A are located at N magnetic During the original position of pole, the corresponding Hall detection components 20B of lower floor magnet assembly 10B are located at 1/2 position of N magnetic poles, accordingly Ground, when opening direction of the x layers of magnet assembly 10 into Fig. 3 shown in arrow is moved, the corresponding Hall inspections of lower floor magnet assembly 10B The induced signal Hall detection components 20A corresponding relative to upper strata magnet assembly 10B for surveying component 20B outputs is delayed 90 °.

According to one embodiment of present invention, Hall detection components 20 generate the first level and just when just to N magnetic poles Second electrical level is generated during to S magnetic poles, or Hall detection components 20 generate the first level and just to first when just to N magnetic poles Second electrical level is generated during white space, or Hall detection components 20 generate the first level and just to when just to S magnetic poles Second electrical level is generated during two white spaces, x road feels induction signal can construct the combination of y kinds level state, y>x.Wherein, according to this hair Bright one embodiment, the quantity y of level state combination is x times of the level state quantity of each road feel induction signal, i.e. y= 2x。

As shown in figure 14, control unit 30 includes：Timer 301 and control chip 302.

Wherein, timer 301 in any of y kinds level state combination level state by being combined into based on current start When, timing is carried out with the duration of every kind of level state combination in being combined to y kinds level state；Control chip 302 and timing Device 301 is connected, and control chip 302 is also connected with x Hall detection components 20, and control chip 302 is in any level state group The duration of conjunction judges that clamping stagnation occurs for moving component when being more than preset time threshold.

The pre-determined distance that is, width for the N magnetic poles or S magnetic poles that x layers of magnet assembly 10 match magnet assembly 10 staggers, The preset phase angle so that the x road feels induction signal that x Hall detection components 20 are exported respectively staggers successively, thus synchronization can shape Combined into different level states.Control chip 302 is by detecting whether the duration that each level state is combined exceedes in advance If time threshold is that can determine whether whether moving component occurs clamping stagnation.Thus, using multi-layered magnetic component, magnet assembly stagger arrangement point Cloth, while being equipped with the Hall detection components of same number, can further shorten detection time at double, can reach reduction detection at double The effect of time.

Specifically, illustrate so that the interval of magnet assembly 10 is full of N magnetic poles and S magnetic poles as an example, when moving component is moved, x Layer magnet assembly 10 is with moving component synchronizing moving, and x Hall detection components 20 are fixed, on every layer of magnet assembly 10 N magnetic poles and S magnetic poles are alternately across corresponding Hall detection components 20, and thus, x Hall detection components 20 produce dutycycle respectively For 50% low and high level pulse train.

Corresponding magnetic pole on x layers of magnet assembly 10 staggers pre-determined distance successively according to above-mentioned formula d=D/p/x, correspondingly, Two neighboring Hall detection components 20 can obtain differing the waveform at 180 °/x phase angles.Thus, it is possible to one in the waveform of every road Cycle be divided into 2x kinds level state combination, also, every kind of level state combination duration tn be any road signal height The 1/x of the duration of level state or low level state, i.e. tn=s/v/x, wherein, r is the mobile speed of x layers of magnet assembly 10 Degree is the movement velocity of moving component, and s is the half of N magnetic poles and the width of S magnetic poles on magnet assembly 10, and x is magnet assembly 10 The number of plies.Thus, it is distributed using the stagger arrangement of multi-layered magnetic component, can further shortens detection time at double, for example with how many layer Magnet assembly can reduce detection time how many times.

It should be appreciated that when being spaced apart multiple N magnetic poles in the detection faces of magnet assembly 10, s is magnet assembly 10 The half of the width of upper N magnetic poles and the first white space；When being spaced apart multiple S magnetic poles in the detection faces of magnet assembly 10, s For the half of the width of S magnetic poles and the second white space on magnet assembly 10.

As shown in figure 15, by taking x=2 as an example, the two-way ripple at the exportable 90 ° of phase angles that respectively lag of two Hall detection components 20 90 ° delayed relative to Hall detection components 20A output waveform of shape, i.e. Hall detection components 20B output waveform.Thus, may be used So that a cycle in per road waveform is divided into four kinds of level states combinations, i.e., four kinds level states combinations are respectively 10,11, 01st, 00, wherein, 1 represents high level, and 0 represents low level, also, the duration tn of every kind of level state combination is any road The high level of signal or the 1/2, tn=s/v/2 of the duration of low level state, so that detection sensitivity is improved twice.

When clamping stagnation occurs for moving component, the corresponding magnetic pole of each Hall detection components 20 no longer changes, so each suddenly You can be continuously high level or be continuously low level the output level of detection components 20.As shown in figure 16, moving component is in t1 Moment occurs clamping stagnation and recovered at the t2 moment, and tn is the duration that every kind of level state combination during clamping stagnation does not occur, and td is pre- If time threshold, when occurring clamping stagnation, the level state that two-way waveform remains current is constant, sentences when the duration being more than td Disconnected moving component clamping stagnation.Wherein, preset time threshold td=k*tn, k span are 1-4, preferably 1.5.

As described above, the embodiment of the present invention detection moving component whether clamping stagnation detection process it is as follows：

The open detection function of control chip 302 when moving component is moved, and control timer 301 to start timing, control Chip 302 can gather the induced signal that x Hall detection components 20 are exported, and be jumped when low and high level occurs for any one road feel induction signal Timer 301 is controlled to reset during change, control chip 302 can determine whether whether the clocking value of timer 301 is more than preset time threshold Td, if the clocking value of timer 301 is more than preset time threshold td, judges moving component clamping stagnation, control chip 302 is exported Clamping stagnation protection signal, to perform protection act, for example, controls moving component to stop mobile or move backward；If timer 301 Clocking value be less than or equal to preset time threshold td, then judge that clamping stagnation do not occur for moving component, control chip 302 is controllable to move Part continues to rotate forward.

It should be appreciated that every layer of interval of magnet assembly 10 is full of N magnetic poles and the first white space and every layer of magnetic group Embodiment of the interval of part 10 full of S magnetic poles and the second white space is full of N magnetic poles and S magnetic with foregoing every layer of magnet assembly 10 interval Extremely essentially identical, difference is, when every layer of interval of magnet assembly 10 is full of N magnetic poles and the first white space, N magnetic poles and the first sky White region is full of S magnetic poles and the second blank alternately across corresponding Hall detection components 20, and every layer of interval of magnet assembly 10 During region, S magnetic poles and the second white space are no longer described in detail here alternately across corresponding Hall detection components 20.

Further, as shown in figure 17, the detection control apparatus of moving component also includes x output circuit in air conditioner 40, x output circuits 40 are corresponded with the output end of x Hall detection components 20 to be connected, and each output circuit 40 includes：The Two resistance R2 and 3rd resistor R3, second resistance R2 and 3rd resistor R3 are connected in series, the electricity of the second resistance R2 of series connection and the 3rd Resistance R3 one end is connected with default power supply VCC, the second resistance R2 and 3rd resistor R3 of the series connection other end and control unit 30 I.e. control chip 302 is connected, and has node between the second resistance R2 and 3rd resistor R3 of series connection, and node is examined with corresponding Hall The output end for surveying component 20 is connected.

Wherein, second resistance R2 is pull-up resistor, and 3rd resistor R3 is current-limiting resistance.

That is, each Hall detection components 20 can power for 5V, so that the exportable width of each Hall detection components 20 It is worth the low and high level pulse train for 5V, each low and high level pulse train is supplied to control unit by corresponding output circuit 30, control unit 30 can carry out timing to the duration of the level state combination of x roads low and high level pulse train, and pass through Whether the multilevel iudge moving component of timing time and preset time threshold occurs clamping stagnation.

In addition, according to the specific embodiment of the present invention, as shown in Figures 18 and 19, motor 100 can drive door-plate 300.In the air conditioner of the embodiment of the present invention detection control apparatus of moving component can door-plate 300 whether clamping stagnation is for example whether run into Barrier.Specifically, by interval on every layer of magnet assembly 10 full of exemplified by N magnetic poles and S magnetic poles, x layers of magnet assembly 10 with During 300 synchronizing moving of door-plate, N magnetic poles and S magnetic poles on every layer of magnet assembly 10 enter alternately across corresponding Hall detection components And x Hall detection components is exported stable low and high level pulse train respectively, dutycycle is 50%.

When clamping stagnation occurs for door-plate 300, for example, there is foreign matter to block door-plate 300 or when finger is stretched in wherein accidentally, door-plate 300 Slack, the corresponding magnetic pole of each Hall detection components no longer changes, and the output level of each Hall detection components can continue For high level or it is continuously low level.Control unit 30 is by detecting whether the duration that each level state is combined exceedes Preset time threshold is that can determine whether whether door-plate 300 occurs clamping stagnation and for example run into barrier.
