Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a control method of a motorized window treatment, which can be applied to the motorized window treatment, in particular to a control system of the motorized window treatment. The electric curtain comprises a motor and at least two Hall devices arranged in the motor.

By adopting the electric curtain provided by the embodiment of the application, a user can open the curtain or close the curtain in a hand-pulling starting mode. Taking curtain opening as an example, a user can pull the curtain cloth for a certain distance in the curtain opening direction, the motor of the electric curtain can passively rotate under the influence of the curtain cloth pulled by the user, and the passive rotation direction is the same as the pulling direction of the user. The electric curtain can determine the current rotation direction when the motor rotates passively, and then the motor is controlled to rotate continuously in the current rotation direction to drive the curtain cloth to expand towards the direction that a user pulls the curtain, so that the hand-pulling starting is realized.

The following will describe a control method of a motorized window treatment provided in an embodiment of the present application in detail with reference to specific embodiments, as shown in fig. 1, the specific steps are as follows:

step 101, acquiring at least two pulse signals generated by a cutting magnetic field in the process that at least two Hall devices rotate along with a motor.

In implementation, the electric window curtain may be provided with a magnetic component in advance, and the magnetic component may generate a magnetic field. In the process that the motor passively rotates along with the cord fabric pulled by a user, each Hall device arranged in the motor rotates along with the motor so as to cut a magnetic field and generate a pulse signal. Thus, the motorized window treatment may obtain at least two pulse signals.

And 102, determining the change condition of the output levels of at least two pulse signals.

In implementation, the motorized window treatment may perform data processing on each collected pulse signal to obtain an output level of the pulse signal. Because the direction of the cutting magnetic field of each Hall device changes along with the rotation of the motor, the output level of the pulse signal determined by the electric curtain can change in height, and the change in height can circulate according to a fixed rule, namely, the change condition of the output level is obtained by the electric curtain processing the pulse signal.

Thus, the motorized window treatment can determine a change in the output level of the at least two pulse signals.

Fig. 2 is a schematic diagram of a variation of an output level according to an embodiment of the present application, where a signal a and a signal B are two pulse signals generated by two hall devices cutting a magnetic field. The variation of the output level of the pulse signal can be represented as table 1:

TABLE 1

Signal A	1	0	0	1	1	0	0	1
									Signal B	0	0	1	1	0	0	1	1

And 103, determining the current rotation direction of the motor according to the change conditions of the output levels of the at least two pulse signals and a preset rotation direction judgment rule.

In an implementation, the preset rotation direction determination rule may be a rising edge trigger determination, that is, when an output level of a certain pulse signal changes from a preset low level to a preset high level, a current rotation direction of the motor is determined. The rotation direction determination rule may also be a falling edge trigger determination, that is, when the output level of a certain pulse signal changes from a preset high level to a preset low level, the current rotation direction of the motor is determined.

Because at least two Hall devices cut the magnetic field successively, consequently, the output level of at least two pulse signal is different at the same moment.

The implementation manner of determining the current rotation direction of the motor of the electric curtain according to the change condition of the output levels of the at least two pulse signals and the rotation direction judgment rule can be diversified aiming at the difference of the output levels of the at least two pulse signals and the difference of the rotation direction judgment rule. The specific processing procedure will be described in detail later.

And 104, controlling the motor to continuously rotate in the current rotating direction to drive the curtain cloth to be unfolded or furled.

In implementation, if the current rotation direction is the direction of pulling the curtain cloth open, the electric curtain control motor continues to rotate in the current rotation direction, and the curtain cloth can be driven to be unfolded. If the current rotation direction is the direction for drawing the curtain cloth, the electric curtain control motor continuously rotates in the current rotation direction to drive the curtain cloth to be drawn.

The specific processing procedure of the electric curtain control motor rotating continuously in the current rotating direction can refer to the processing procedure of controlling the motor to rotate in a certain rotating direction in the related art, and is not repeated in the application.

In the embodiment of the application, the electric curtain can obtain at least two pulse signals generated by a cutting magnetic field in the process that at least two Hall devices rotate along with the motor; determining the change condition of the output levels of at least two pulse signals; determining the current rotation direction of the motor according to the change conditions of the output levels of at least two pulse signals and a preset rotation direction judgment rule; and controlling the motor to continuously rotate in the current rotation direction to drive the curtain cloth to be unfolded or folded.

The current rotation direction of the motor can be determined according to the change condition of the output levels of at least two pulse signals and the rotation direction judgment rule, so that the rotation direction of the motor can be simply and effectively determined without a complex mechanical structure, and further the hand-pulling starting is realized.

In addition, the code for realizing the control function of the electric curtain has the advantages of simple writing and less instructions in the software control layer of the electric curtain.

Optionally, taking an example that the at least two pulse signals include a first pulse signal and a second pulse signal, an embodiment of the present application provides an implementation manner for determining a current rotation direction of the motor based on a rotation direction determination rule and a change condition of output levels of the at least two pulse signals, as shown in fig. 3, including:

step 301 determines the output level of the second pulse signal when the output level of the first pulse signal is changed from the first level to the second level.

In an embodiment, the motorized window treatment may determine a transition timing at which the output level is changed from the first level to the second level according to a change in the output level of the first pulse signal. The motorized window treatment may then determine the transition time, the output level of the second pulse signal.

Thereafter, the motorized window treatment may determine whether the output level of the second pulse signal is the first level or the second level.

And 302, if the output level of the second pulse signal is the first level, determining the current rotation direction of the motor to be the first rotation direction.

And step 303, if the output level of the second pulse signal is the second level, determining that the current rotating direction of the motor is a second rotating direction opposite to the first rotating direction.

Optionally, the first level is a preset low level, the second level is a preset high level, and the rotation direction determination rule may be a rising edge trigger determination, that is, when the output level of a certain pulse signal changes from the preset low level to the preset high level, the current rotation direction of the motor is determined.

Taking the first level as 0, the second level as 1, and the first rotation direction as the forward rotation direction of the motor as an example, when the output level of the first pulse signal is changed from the first level 0 to the second level 1, that is, when a rising edge occurs, the motorized window shade may determine the output level of the second pulse signal. If the output level of the second pulse signal is 0, the motorized window treatment may determine that the current rotation direction of the motor is the first rotation direction, i.e., the forward rotation direction. If the output level of the second pulse signal is 1, the motorized window treatment may determine that the current rotation direction of the motor is a second rotation direction opposite to the first rotation direction, i.e., a reverse rotation direction.

For example, as shown at a position indicated by an arrow 1 in fig. 2, when the output level of the first pulse signal a is changed from the first level 0 to the second level 1, that is, when a rising edge occurs, the motorized window treatment may determine the output level of the second pulse signal B to obtain the second level 1, and the motorized window treatment may determine that the current rotation direction of the motor is the reverse rotation direction.

Optionally, the first level is a preset high level, the second level is a preset low level, and the rotation direction determination rule may be that a falling edge triggers determination, that is, when an output level of a certain pulse signal changes from the preset high level to the preset low level, a current rotation direction of the motor is determined.

Taking the first level as 1, the second level as 0, and the first rotation direction as the forward rotation direction of the motor as an example, the output level of the second pulse signal is determined when the output level of the first pulse signal is changed from the first level 1 to the second level 0. If the output level of the second pulse signal is 1, the motorized window treatment may determine that the current rotation direction of the motor is the first rotation direction, i.e., the forward rotation direction. If the output level of the second pulse signal is 0, the motorized window treatment may determine that the current rotation direction of the motor is a second rotation direction opposite to the first rotation direction, i.e., a reverse rotation direction.

For example, as shown at a position indicated by an arrow 2 in fig. 2, when the output level of the first pulse signal a is changed from the first level 1 to the second level 0, that is, when a falling edge occurs, the motorized window treatment may determine the output level of the second pulse signal B to obtain the second level 0, and the motorized window treatment may determine that the current rotation direction of the motor is the reverse rotation direction.

In an embodiment of the present application, the motorized window treatment may determine the output level of the second pulse signal when the output level of the first pulse signal is changed from the first level to the second level. If the output level of the second pulse signal is the first level, the motorized window treatment may determine that the current rotational direction of the motor is the first rotational direction. If the output level of the second pulse signal is the second level, the motorized window treatment may determine that the current rotational direction of the motor is a second rotational direction opposite to the first rotational direction. Therefore, the current rotating direction of the motor can be quickly and accurately determined by the electric curtain through the change condition of the output levels of at least two pulse signals and the rotating direction judgment rule, so that the use experience of a user can be improved.

Optionally, taking an example that the at least two pulse signals include a first pulse signal and a second pulse signal, an embodiment of the present application provides another implementation manner for determining the current rotation direction of the motor based on the rotation direction determination rule and the change condition of the output levels of the at least two pulse signals, as shown in fig. 4, including:

step 401, if the output levels of the first pulse signal and the second pulse signal are both the first level, determining that the output level is changed to the target pulse signal of the second level first.

In an implementation, the motorized window treatment may determine whether the output levels of the first pulse signal and the second pulse signal are both the first level at the same time according to a variation of the output levels of the two pulse signals. If the output levels of the first pulse signal and the second pulse signal are both the first level, the electric curtain can determine that the output level is changed into the pulse signal of the second level first, and then the target pulse signal is obtained.

And 402, if the target pulse signal is the second pulse signal, determining the current rotating direction of the motor to be the first rotating direction.

And 403, if the target pulse signal is the first pulse signal, determining the current rotation direction of the motor to be a second rotation direction opposite to the first rotation direction.

Optionally, the first level is a preset low level, the second level is a preset high level, and the rotation direction determination rule may be a rising edge trigger determination, that is, when the output level of a certain pulse signal changes from the preset low level to the preset high level, the current rotation direction of the motor is determined.

Taking the first level as 0, the second level as 1, and the first rotation direction as the forward rotation direction of the motor as an example, when the output levels of the first pulse signal and the second pulse signal are both the first level 0, the motorized window shade may determine the target pulse signal whose output level is first changed to the second level 1. If the target pulse signal is the second pulse signal, the motorized window treatment may determine that the current rotational direction of the motor is the first rotational direction. If the target pulse signal is a first pulse signal, the motorized window treatment may determine that the current rotational direction of the motor is a second rotational direction opposite the first rotational direction, i.e., a reverse rotational direction.

For example, as shown in the position indicated by the arrow 3 in fig. 2, when the output levels of the first pulse signal a and the second pulse signal B are both the first level 0, the motorized window shade may determine that the target pulse signal whose output level is first changed to the second level 1, and obtain the second pulse signal B. The motorized window treatment may determine that the current rotational direction of the motor is a reverse rotational direction.

Optionally, the first level is a preset high level, the second level is a preset low level, and the rotation direction determination rule may be that a falling edge triggers determination, that is, when an output level of a certain pulse signal changes from the preset high level to the preset low level, a current rotation direction of the motor is determined.

Taking the first level as 1, the second level as 0, and the first rotation direction as the forward rotation direction of the motor as an example, when the output levels of the first pulse signal and the second pulse signal are both the first level 1, the motorized window shade may determine the target pulse signal whose output level is first changed to the second level 0. If the target pulse signal is a second pulse signal, the motorized window treatment may determine that the current rotational direction of the motor is a second rotational direction opposite the first rotational direction, i.e., a reverse rotational direction.

For example, as shown in fig. 2 at the position indicated by the arrow 4, when the output levels of the first pulse signal a and the second pulse signal B are both the first level 1, the motorized window shade may determine that the target pulse signal whose output level is first changed to the second level 0, and obtain the second pulse signal B. The motorized window treatment may determine that the current rotational direction of the motor is a reverse rotational direction.

In this embodiment, when the output levels of the first pulse signal and the second pulse signal are both the first level, the motorized window shade may determine the target pulse signal whose output level is first changed to the second level. If the target pulse signal is the second pulse signal, the motorized window treatment may determine that the current rotational direction of the motor is the first rotational direction; if the target pulse signal is a first pulse signal, the motorized window treatment may determine that the current rotational direction of the motor is a second rotational direction opposite the first rotational direction. Therefore, the current rotating direction of the motor can be quickly and accurately determined by the electric curtain through the changing conditions of the output levels of at least two pulse signals, so that the use experience of a user can be improved.

Based on the same technical concept, the embodiment of the present application further provides a motorized window treatment, which includes: the device comprises a motor, at least two Hall devices arranged in the motor and a processing device; wherein the content of the first and second substances,

Wherein, the motor includes a driving shaft 510, at least two hall devices 520, a magnetic member 530, and a circuit board 540. At least two hall devices 520 are disposed on the circuit board 540, and since they are covered by the magnetic member 530, the detailed shapes of the at least two hall devices 520 are not shown in the drawings, and only the disposition positions are shown. During the rotation of the at least two hall devices 520 with the motor, the magnetic field generated by the magnetic component 530 can be cut to generate at least two pulse signals.

Alternatively, the included angle between the at least two hall devices 520 and the drive shaft 510 may be less than 180 degrees.

When the included angle between the at least two hall devices 520 and the driving shaft 510 is equal to 180 degrees, that is, when the at least two hall devices 520 are arranged symmetrically to the driving shaft 510, the at least two hall devices 520 may generate the same pulse signal during the rotation with the motor to cut the magnetic field due to the influence of the magnetic field distribution.
