Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0024] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Current motorized blinds are typically based on percentage control, which includes two dimensions: the degree of opening (opening / closing) and angle adjustment. Specifically, as the percentage control increases from 0% (when the blinds are fully closed and the window is completely unobstructed) to 100% (when the blinds are fully open and the window is completely obstructed), the motor rotates. During the motor's rotation, the opening / closing degree is first increased (from 0% to 100%) to complete full opening. Finally, within a very short percentage control stroke (e.g., 5%), the angle is adjusted from 0° (when the slats are perpendicular to the horizontal plane) to 90° (when the slats are parallel to the horizontal plane) (the opening / closing degree remains at 100% during this phase). However, for a user to fix the motorized blinds at a specific slat angle and press the "stop" button at a specific time is difficult to operate. Therefore, percentage-based adjustment schemes cannot precisely adjust the motorized blinds to a specific angle desired by the user, resulting in poor control precision.

[0026] To improve the slat angle adjustment accuracy of electric curtains, this application provides an electric curtain control method, applied to electric curtains or their control unit, as described above. Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the electric curtain control method of this application. The electric curtain control method includes: Step S10: In response to the control command, determine the target control parameter corresponding to the control command. The target control parameter is the target opening degree or the target blade angle. The control commands are user-inputted commands, including target control parameters, which are specific opening degrees (e.g., 80%) or blade angles (e.g., 45°). Users can achieve precise control of motorized blinds by inputting control commands with opening degrees or blade angles.

[0027] In practical applications, a feasible electric curtain control system is as follows: Figure 2 As shown, users can send control signals (including control commands) to the electric curtains via a control terminal (remote control, mobile phone or other control device) to achieve remote control of the electric curtains.

[0028] Step S20: Based on the preset mapping relationship between control parameters and motor Hall values, determine the target Hall value corresponding to the target control parameters; It should be noted that motorized curtains adjust the opening degree and slat angle through motor operation. A Hall effect sensor on the motor rotor detects the number of pulses generated by the motor's rotation. Essentially, the sensor generates a pulse signal (Hall value) every time the motor rotates a certain angle. By counting the number of pulses, the number of rotations or the angle of the motor can be accurately calculated, thus indirectly determining the actual position of the curtains.

[0029] The control parameters include either the target opening degree or the target blade angle. The preset mapping relationship between the control parameters and the motor's Hall value includes both the mapping relationship between the opening degree and the Hall value, and the mapping relationship between the blade angle and the Hall value; these two mapping relationships are independent of each other. The mapping relationship can be represented in the form of a two-dimensional mapping table, where each opening degree or blade angle uniquely corresponds to a Hall value. Given the target control parameters, the corresponding target Hall value can be looked up in the two-dimensional mapping table.

[0030] Step S30: Control the operation of the electric curtains according to the target Hall value.

[0031] In this step, controlling the operation of the electric curtain based on the target Hall value means controlling the motor of the electric curtain to run until the collected Hall value reaches the target Hall value, and then stopping the operation. At this time, the Hall value corresponds to a target opening degree or a target blade angle, so that the electric curtain can not only achieve precise control of the opening degree, but also precise control of the blade angle.

[0032] Furthermore, in one embodiment, the mapping relationship includes at least a first interval corresponding to the opening degree and a second interval corresponding to the blade angle, and the boundary between the first interval and the second interval is the first travel point; Step S30, which controls the operation of the electric curtain based on the target Hall value, may include: Step S31: If the current Hall value and the target Hall value corresponding to the motor of the electric curtain are both in the first interval or the second interval, then control the motor to run to the target Hall value. Understandably, when adjusting the opening degree or slat angle of motorized curtains, there are two scenarios: one is that the current Hall effect value and the target Hall effect value are within the same travel range, and the other is that they are within different travel ranges. Within the same travel range, there are two scenarios: one is that the motorized curtain is currently within the opening degree adjustment range, i.e., the current opening degree is between 0% and 100% (while the slat angle is 0°), and the target control parameter is also the target opening degree; in this case, adjustment only needs to be made within the adjustment range containing the target opening degree (i.e., the first range); the other is that the motorized curtain is currently within the slat angle adjustment range, i.e., the current slat angle is between 0° and 90° (while the opening degree is 100%), and the target control parameter is also the target slat angle; in this case, adjustment only needs to be made within the adjustment range containing the target slat angle (i.e., the second range).

[0033] Furthermore, after adjustment is completed, the target opening degree or target blade angle is output to the server and / or control terminal to achieve visual feedback and synchronization.

[0034] Step S32: If the current Hall value corresponding to the motor of the electric curtain is in the first interval and the target Hall value is in the second interval, then control the motor to run to the target Hall value, and output the current opening degree when the Hall value of the motor is equal to the first stroke point; In different travel ranges, one scenario involves the motorized curtain currently being in the opening / closing adjustment range (blade angle at 0°), but the target control parameter is the target blade angle. In this case, cross-range adjustment is required. First, the opening / closing degree of the motorized curtain is controlled to reach 100%, then the blade angle is gradually increased until the Hall value collected at the motor reaches the target Hall value (at which point the blade angle in the control command is achieved). Simultaneously, when the opening / closing degree of the motorized curtain just reaches 100%, the current opening / closing degree is simultaneously output to remind the user of the current opening / closing status and that it is currently entering the blade angle adjustment range, allowing the user to monitor the device status in real time.

[0035] Furthermore, after adjustment is complete, the target blade angle is output to the server and / or control terminal to achieve visual feedback and synchronization.

[0036] For example, when the motor's Hall value is in the first interval and a control command for the blade angle is received: it first runs to the third stroke point (output opening degree 0%), and then runs to the target blade angle in the second interval and reports it. Example: When the motor's Hall value is in the first interval and the opening degree is 30%, it receives a "30°" command, first runs to the first stroke point, and then moves down to the position where the blade angle is 30°.

[0037] Step S33: If the current Hall value corresponding to the motor of the electric curtain is in the second interval and the target Hall value is in the first interval, then control the motor to run to the target Hall value, and output the current blade angle when the Hall value of the motor is equal to the first stroke point.

[0038] Another scenario involves different travel ranges. The motorized blind is currently in the slat angle adjustment range (opening / closing degree is 100%), but the target control parameter is the target opening / closing degree. In this case, cross-range adjustment is required. First, the slat angle is controlled to decrease to 0°, then the opening / closing degree is gradually reduced until the Hall value collected at the motor reaches the target Hall value (at which point the opening / closing degree in the control command is achieved). Simultaneously, when the slat angle just reaches 0°, the current slat angle is output to remind the user of the current slat angle and that the blind is currently entering the opening / closing degree adjustment range, allowing the user to monitor the device status in real time.

[0039] Furthermore, after adjustment is complete, the target opening degree is output to the server and / or control terminal to achieve visual feedback and synchronization.

[0040] For example, when the motor's Hall value is in the second range and a control command for the opening degree is received: it first runs to the first stroke point (output blade angle 0°), then runs to the target opening degree in the first range and reports it. Example: When the motor's Hall value is in the second range and the blade angle is 60° and a "50%" command is received, it first goes to the first stroke point, then moves up to the position where the opening degree is 50%.

[0041] For ease of understanding, the control methods for electric blinds are as follows, with the control parameters being opening / closing degree and blade angle: Figure 3 As shown, the control command is first parsed to determine if the corresponding control parameter is the degree of opening. If it is the degree of opening, the Hall value of the current motor is determined to be in the first interval. If it is not in the first interval, the Hall value corresponding to the degree of opening is determined, and the blade angle is output as 0° when it equals the first stroke point. Then, the motor runs to the first interval. If it is in the first interval, the Hall value corresponding to the degree of opening is directly determined, and the motor is finally controlled to run to the position of the Hall value corresponding to the degree of opening, and the degree of opening is output. If it is not the degree of opening, it is the blade angle. The control process is as follows: the Hall value of the current motor is determined to be in the first interval. If it is not in the first interval, the Hall value corresponding to the blade angle is determined. If it is in the first interval, the Hall value corresponding to the blade angle is determined, and the degree of opening is output as 0% when it equals the first stroke point. The motor runs to the second interval, and the motor is finally controlled to run to the position of the Hall value corresponding to the blade angle, and the blade angle is output.

[0042] Compared to the traditional percentage control strategy, the embodiments of this application add a first stroke point in the motor stroke to achieve physical isolation between the opening degree and the blade angle control.

[0043] In another feasible embodiment, the electric curtain control method may further include: Step A10: Control the electric curtain to run until the opening degree is 0% and the blade angle is 0°, and determine the current Hall value of the motor as the second stroke point; Step A20: Control the electric curtain to operate until the opening degree is 100% and the blade angle is 90°, and determine the current Hall value of the motor as the third stroke point; Step A30: Determine the first stroke point by adjusting the opening degree or blade angle of the electric curtain, wherein the first stroke point is the critical point for controlling the opening degree and blade angle. Step A40: Determine the first interval and the second interval based on the first travel point, the second travel point, and the third travel point.

[0044] This application embodiment provides a method for setting first, second, and third travel points and first and second intervals. The second travel point determined in step A10 corresponds to the travel point at the uppermost extreme position of the electric curtain, and the third travel point determined in step A20 corresponds to the travel point at the lowermost extreme position of the electric curtain. Furthermore, the first travel point in step A30, used to distinguish between the first and second intervals, is a critical point for controlling the opening and closing degree and slat angle of the electric curtain. Figure 4 As shown, one side of the first travel point belongs to the first interval, and the other side belongs to the second interval. Finally, the first and second intervals are divided according to the first, second, and third travel points.

[0045] Furthermore, step A30, which determines the first travel point by adjusting the slat angle of the electric curtain, may include: Step A31: When the slat angle of the electric curtain is greater than 0°, control the slat angle of the electric curtain to decrease. Step A32: When the slat angle of the electric curtain decreases to 0°, the current Hall value of the motor is determined as the first travel point.

[0046] This application provides a feasible method for determining the first travel point by adjusting the slat angle of an electric curtain. When the slat angle of the electric curtain is greater than 0° (belonging to the second interval), the slat angle is reduced to approach 0°, and the current Hall value is determined as the first travel point at the moment it just reaches 0°. Because the motor enters the first interval and begins to adjust the opening degree after this time point, the Hall value at this time point can be used as the first travel point.

[0047] In another feasible embodiment, step A30, which determines the first travel point by adjusting the opening and closing degree of the electric curtain, may include: Step A33: When the opening degree of the electric curtain is less than 100%, control the opening degree of the electric curtain to increase. Step A34: When the opening degree of the electric curtain increases to 100%, the current Hall value of the motor is determined as the first stroke point.

[0048] This application provides a feasible method for determining the first travel point by adjusting the opening degree of an electric curtain. When the opening degree of the electric curtain is less than 100% (belonging to the first interval), the opening degree is increased to approach 100%, and the current Hall value is determined as the first travel point at the moment it just reaches 100%. Because after this time point, the motor enters the second interval and begins to adjust the blade angle, the Hall value at this time point can be used as the first travel point.

[0049] Further, step A40, which determines the first interval and the second interval based on the first travel point, the second travel point, and the third travel point, may include: Step A41: Determine the first interval based on the first travel point and the second travel point, wherein the upper limit of the first interval is the second travel point, and the lower limit of the first interval is the first travel point; Step A42: Determine the second interval based on the first travel point and the third travel point, wherein the upper limit of the second interval is the first travel point and the lower limit of the second interval is the third travel point.

[0050] like Figure 4 As shown, the first stroke point, the second stroke point, and the third stroke point divide the entire stroke of the motor into two parts. The first interval is used to control the opening degree, the upper limit is the second stroke point, and the lower limit is the first stroke point; the second interval is used to control the blade angle, the upper limit is the first stroke point, and the lower limit is the third stroke point.

[0051] In one feasible embodiment, a feasible travel interval setting process is as follows: Figure 5 As shown, first determine if the motor has a stroke. If not, set the stroke (referring to determining the second and third stroke points, corresponding to steps A10 to A20). After setting the motor stroke, adjust the curtain blades from 90 degrees to 0 degrees, and just as they fall to 0 degrees, set the third stroke point, and control the device to generate the first and second intervals with the third stroke point as the critical point.

[0052] In another feasible embodiment, after step A41 of determining the first interval based on the first travel point and the second travel point, the electric curtain control method may further include: Step A43: Based on the preset opening degree adjustment step size and opening degree adjustment range, calculate the number of opening degree adjustment steps and multiple first opening degrees, wherein the number of first opening degrees is equal to the number of opening degree adjustment steps; Step A44: Divide the first interval into multiple equal parts to obtain multiple first Hall values, wherein the number of first Hall values ​​is equal to the number of opening and closing adjustment steps; Step A45: Store each first Hall value and each first opening degree respectively to obtain the mapping relationship between the opening degree and the Hall value.

[0053] This application provides a method for generating a mapping relationship between opening degree and Hall value, which involves uniformly dividing a first interval and an opening degree adjustment range and storing them accordingly. Specifically, the opening degree adjustment range can be 0%~100%, and the opening degree adjustment step size can be 1%. Then, the number of opening degree adjustment steps = 100% / 1%+1 = 101, and each first opening degree is 0%, 1%, 2%, 3%, ..., 98%, 99%, 100%, for a total of 101 opening degree values. In addition, the Hall value of the first interval is further divided into multiple equal parts. For example, if the first interval is [a, b], then the step size of the arithmetic sequence formed by multiple first Hall values ​​is (ba) / 100, for a total of 101 first Hall values.

[0054] Furthermore, in the process of storing each first Hall value and each first opening degree respectively, they are sorted and matched according to their numerical values. For example, the opening degree corresponding to the first Hall value a is 0%, the opening degree corresponding to the first Hall value a+(ba) / 100 is 1%, and so on, the opening degree corresponding to the first Hall value b is 100%.

[0055] In another feasible embodiment, after step A42 of determining the second interval based on the first travel point and the third travel point, the motorized curtain control method may further include: Step A46: Based on the preset angle adjustment step size and blade angle adjustment range, calculate the angle adjustment step number and multiple first blade angles, wherein the number of first blade angles is equal to the angle adjustment step number; Step A47: Divide the second interval into multiple equal parts to obtain multiple second Hall values, where the number of second Hall values ​​is equal to the number of angle adjustment steps; Step A48: Store each second Hall value and each first blade angle respectively to obtain the mapping relationship between blade angle and Hall value.

[0056] This application provides a method for generating a mapping relationship between blade angle and Hall value, which involves uniformly dividing a second interval and the blade angle adjustment range and storing them accordingly. Specifically, the blade angle adjustment range can be 0°~90°, and the blade angle adjustment step size can be 1°. Therefore, the number of blade angle adjustment steps = 90° / 1° + 1 = 91, and the first blade angles are 0°, 1°, 2°, 3°, ..., 88°, 89°, and 90°, totaling 91 1° values. Furthermore, the Hall value of the second interval is further divided into multiple equal parts. For example, if the first interval is [c, d], the step size of the arithmetic sequence formed by multiple second Hall values ​​is (dc) / 90, resulting in 91 second Hall values. It is understood that since the Hall value range of the second interval is narrower than that of the first interval, the difference between adjacent second Hall values ​​in the second interval is generally significantly smaller than the difference between adjacent first Hall values ​​in the first interval.

[0057] Furthermore, during the process of storing each second Hall value and each first blade angle respectively, they are sorted according to their numerical values. For example, the blade angle corresponding to the second Hall value c is 0°, the blade angle corresponding to the second Hall value c+(dc) / 90 is 1°, and so on, the blade angle corresponding to the second Hall value d is 90°.

[0058] In summary, this embodiment of the application supports precise control of the blade angle by equally dividing the Hall values ​​for opening degree and blade angle into upper and lower intervals respectively. In particular, the control of the blade angle in the second interval achieves precise adjustment at the "degree" level, overcoming the limitations of existing percentage-based indirect adjustment and meeting the needs of fine-tuning. Moreover, based on existing hardware devices, no new complex hardware is required; only the control logic and calibration algorithm are optimized, making it easy to scale up and deploy.

[0059] In another feasible embodiment, after the user sends a cancellation command to the motorized curtain via the control terminal, the first travel point record is deleted, the traditional control strategy of single percentage control (100 equal parts) from the upper limit to the lower limit is restored, and the "first travel point not set" status is reported. At this time, the control command containing the blade angle is invalid, which supports the user to flexibly switch the control mode of the motorized curtain and has a higher degree of freedom.

[0060] It should be noted that this example is only for the purpose of assisting in understanding this application and does not constitute a limitation on the electric curtain control method of this application.
