[0047] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0048] The following describes the control method, device, electronic device and storage medium of the electric sunshade device of the embodiment of the present application with reference to the accompanying drawings. In view of the problem of the skylight sunshade being too heavy mentioned in the above background technology, the present application provides a control method for an electric sunshade device, in which the control instruction of the electric sunshade device and the current state data of the sunshade are obtained, and the target state data of the sunshade is determined according to the control instruction, and the execution action and execution data are determined based on the target state data and the current state data. When the execution action is to unfold, the unfolding length is determined according to the execution data, and the motor is controlled to run counterclockwise to drive the sunshade to unfold to the unfolding length. When the execution action is to retract, the retracting length is determined according to the execution data, and the motor is controlled to run clockwise to drive the sunshade to retract to the retracted length. In this way, the problem of the skylight sunshade being too heavy is solved, and the weight of the skylight sunshade is reduced by optimizing the structure of the electric sunshade device and the control method of the electric sunshade device, thereby reducing the difficulty of development.

[0049] Specifically, Figure 1 A flow chart of a control method for an electric sunshade device provided in an embodiment of the present application.

[0050] It should be noted that the control method of the electric sunshade device in the embodiment of the present application is applied to an electric sunshade device, such as Figure 2 As shown, the electric sunshade device includes: a sunshade frame composed of a front crossbeam, a left guide rail, a motor frame and a right guide rail connected end to end in sequence, a motor, a pull wire, a pull plate, a sunshade curtain and a roller envelope, the roller envelope is assembled on the motor frame, the motor is connected to the pull plate through the pull wire, and the pull plate is fixed between the left guide rail and the right guide rail.

[0051] Traditional sunshade systems use flexible shafts to transmit the power of the motor to control the opening and closing of the sunshade. The electric sunshade device of the embodiment of the present application eliminates the flexible shaft and replaces it with a special pull wire, which can simplify the structure, reduce the number of parts, and may improve the response speed and reliability of the system. The special pull wire can be a high-strength fiber material to ensure performance and durability under high loads.

[0052] The rear crossbeam plays a supporting and fixing role in the sunshade structure. In the embodiment of the present application, the rear crossbeam can be eliminated and replaced with a motor frame, which can reduce material usage and reduce weight. At the same time, the motor frame can provide the necessary structural support and motor installation platform.

[0053] The traditional sunshade system includes an independent control module for processing the control signal of the motor. The embodiment of the present application eliminates the control module and integrates the control logic into the body domain controller, thereby reducing the number of electronic components and reducing costs, while improving the system's integration and intelligence level. The embodiment of the present application can use a motor with a Hall sensor to provide precise position and speed feedback, allowing the body domain controller to accurately control the sunshade.

[0054] like Figure 1 As shown, in step S101, the control instruction of the electric sunshade device and the current state data of the sunshade curtain are obtained.

[0055] Among them, the control instructions of the electric sunshade device can come from the user interface, sensor input or remote control system control, which is not specifically limited here.

[0056] Specifically, the user can issue a control command to "expand the sunshade to 50%"; can use the sunshade switch, for example, long press the expansion button, or long press the retraction button; can also remotely control it through a mobile phone APP, the current status data includes the operating status of the sunshade, and the actual position, for example, the sunshade is in the process of expanding and is currently expanded 50%.

[0057] In step S102, target state data of the sunshade is determined according to the control instruction, and an execution action and execution data are determined based on the target state data and current state data.

[0058] Specifically, the target state of the sunshade is determined according to the control instruction. For example, if the control instruction is "unfold to 50%", the target state data is that the sunshade is unfolded to 50% of the total length. If the current state data is that the sunshade is unfolded to 20% of the total length, the execution action is determined to be unfolding, and the execution data is that the unfolded length is 30% of the total length. If the current state data is that the sunshade is unfolded to 80% of the total length, the execution action is determined to be retracting, and the execution data is that the retracted length is 30% of the total length.

[0059] Optionally, in some embodiments, after determining the execution action and execution data based on the target state data and the current state data, it also includes: judging whether the execution data is greater than a preset limit threshold; if the execution data is greater than the preset limit threshold, generating an abnormal reminder instruction, and performing an abnormal reminder based on the abnormal reminder instruction.

[0060] It is understandable that in order to prevent the sunshade from malfunctioning, an over-limit protection mechanism may be provided during the process of unfolding or retracting the sunshade to prevent the sunshade from exceeding its physical limit.

[0061] Specifically, after determining the execution action and data, the system will determine whether these data exceed the preset limit threshold. The limit threshold refers to the maximum or minimum value for safe operation of the system, for example, the maximum angle or speed limit of motor rotation. If the execution data exceeds these safety limits, the system needs to take measures to prevent possible damage or failure. Once it is detected that the execution data exceeds the preset limit threshold, the system will generate an abnormal reminder instruction. The abnormal reminder instruction will trigger an alarm or notification to remind the user or system administrator of potential problems. Among them, the abnormal reminder can be a sound alarm, a visual prompt, or a notification sent through the smart home system, which is not specifically limited here.

[0062] In step S103, when the execution action is expansion, the expansion length is determined according to the execution data, and the motor is controlled to run counterclockwise to drive the sunshade to expand to the expansion length. When the execution action is retraction, the retraction length is determined according to the execution data, and the motor is controlled to run clockwise to drive the sunshade to retract to the retracted length.

[0063] Specifically, when the execution action is retraction, the retraction length is determined according to the execution data, the motor is turned on and runs clockwise, the reel reels the curtain cloth, the winding wheel unwinds the wire, the pull plate is pulled back by the curtain cloth to complete the retraction, the tension spring shortens it to offset the difference in linear speed, and the spring restores the preload; when the execution action is unfolding, the unfolding length is determined according to the execution data, the motor runs counterclockwise, the winding wheel reels the wire, the pull plate is pulled forward, the tension spring is stretched to offset the difference in linear speed, and a tensile force is generated to tighten the curtain cloth. In this embodiment of the application, the motor only acts as an actuator of the motion.

[0064] Optionally, in some embodiments, when controlling the motor to run counterclockwise to drive the sunshade to unfold to the unfolded length, it includes: determining whether there is an obstacle in the unfolding path of the sunshade; if there is an obstacle in the unfolding path, controlling the motor to stop running.

[0065] Specifically, the body domain controller receives signals from sensors, determines the working status of the sunshade, and then controls the operation of the motor to realize the opening and closing of the sunshade and adjust its position. In the process of controlling the motor to run counterclockwise to drive the sunshade to unfold to the unfolded length, the system will perform a series of judgments and operations. During the unfolding of the sunshade, the system will determine whether there are any abnormal conditions in the unfolding path of the sunshade, such as obstacles. If there is an obstacle in the unfolding path, the controller will immediately send a command to the motor to stop it to avoid damaging the sunshade or the motor. In the actual process, the body domain controller detects the obstacle and stops the motor. It can also generate abnormal reminder instructions, which will trigger alarms or notifications to remind users or system administrators of potential problems.

[0066] Optionally, in some embodiments, determining whether there is an obstacle in the deployment path of the sunshade includes: obtaining a stall current of the motor; if the stall current is greater than a preset current threshold, determining that there is an obstacle in the deployment path.

[0067] The preset current threshold may be pre-set by a user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations, which is not specifically limited here.

[0068] Specifically, the motor of the embodiment of the present application can be equipped with a current sensor for real-time monitoring of the motor current. During the unfolding of the sunshade, the body domain controller will continuously obtain the stall current of the motor, that is, the current change caused by the resistance encountered by the motor during operation. The embodiment of the present application sets a current threshold, which is determined based on the current level of the motor when it is working normally and the historical current performance of the motor when encountering obstacles. When the sunshade is unfolded, if the stall current detected by the current sensor exceeds the preset current threshold, the body domain controller will think that there may be an obstacle. After determining that there is an obstacle, the body domain controller will immediately take measures to control the motor to stop running to avoid possible damage caused by continued unfolding of the sunshade.

[0069] Optionally, in some embodiments, determining whether there is an obstacle in the deployment path of the sunshade includes: obtaining pressure sensing data of the pull plate; if the pressure sensing data is greater than a preset pressure threshold, determining that there is an obstacle in the deployment path.

[0070] The preset pressure threshold may be pre-set by a user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations, and is not specifically limited here.

[0071] Specifically, a pressure sensor can be installed on the pull plate of the embodiment of the present application. The pressure sensor can monitor the pressure of the sunshade in real time during the process of unfolding or retracting. The body domain controller determines whether there is an obstacle in the unfolding path of the sunshade through the pressure sensor data. The preset pressure threshold of the embodiment of the present application can be determined based on the pressure range of the sunshade during normal operation and the pressure performance of the sunshade when encountering obstacles in history. When the sunshade is unfolded, the body domain controller will continue to monitor the data of the pressure sensor. If the pressure sensor data exceeds the preset pressure threshold, the system will think that there may be an obstacle in the unfolding path of the sunshade. This judgment is based on the analysis of pressure changes. If the pressure change exceeds the set threshold, the body domain controller will execute the corresponding anti-pinch strategy. Take immediate measures to control the motor to stop running to avoid possible damage caused by the continued unfolding of the sunshade.

[0072] According to the control method of the electric sunshade device proposed in the embodiment of the present application, by obtaining the control instruction of the electric sunshade device and the current state data of the sunshade, and determining the target state data of the sunshade according to the control instruction, the execution action and execution data are determined based on the target state data and the current state data. When the execution action is to unfold, the unfolding length is determined according to the execution data, and the motor is controlled to run counterclockwise to drive the sunshade to unfold to the unfolding length. When the execution action is to retract, the retracting length is determined according to the execution data, and the motor is controlled to run clockwise to drive the sunshade to retract to the retracting length. In this way, the problem of the awning sunshade being too heavy is solved. By optimizing the structure of the electric sunshade device and the control method of the electric sunshade device, the weight of the awning sunshade is reduced, and the development difficulty is reduced.

[0073] Next, the control device of the electric sunshade device proposed in the embodiment of the present application is described with reference to the accompanying drawings.

[0079] Optionally, in some embodiments, when the motor is controlled to run counterclockwise to drive the sunshade to unfold to an unfolded length, the control module 300 includes: a first judgment unit and a control unit.
