Description

Technical Field

[0001] This application relates to the field of smart home technology, and in particular to a method and system for controlling curtain flushing. Background Technology

[0002] Currently, smart curtains generally use individual tubular curtain motors to control the curtains, and the motor's operating stroke is set via smartphones and other devices. However, in group control scenarios for curtain motors, each curtain device receives broadcast or multicast control commands from the main control unit and operates independently according to its own preset speed. Due to the inherent differences in the diameter of the tubular motors, even if the motor speeds are the same, the linear speed of the curtain's rise and fall will deviate, ultimately leading to uneven positioning of multiple curtains when operating synchronously.

[0003] To achieve a level alignment during curtain operation, each curtain device needs to interact frequently and synchronize its instantaneous position and operating status. This process generates a large number of over-the-air data packets. However, wireless communication has limited bandwidth resources, and the transmission of massive data packets can easily cause network latency, congestion, and packet loss, significantly reducing the stability of the wireless communication system and consequently affecting the level alignment of the curtains.

[0020] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] 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.

[0022] 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.

[0023] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device, big data service platform, or curtain flush control system capable of realizing the above functions. The following description uses a curtain flush control system as an example to illustrate this embodiment and the subsequent embodiments.

[0024] Based on this, this application provides a curtain flushing control method, applied to curtain equipment in a curtain assembly, referring to... Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the curtain flush control method of this application.

[0025] Step S11: In response to the control command sent by the master control terminal, the command parameters are parsed and obtained; It should be noted that the parameters of the control command include at least a reference speed and the average Hall value of the curtain group; wherein, the reference speed can be set manually or pre-configured by the system. Furthermore, the parameters of the control command may also include the curtain opening / closing degree and an execution timestamp. The curtain opening / closing degree refers to the relative opening / closing ratio of the smart curtain, for example, the curtain opening / closing degree is set to 80%, 50%, etc.; the execution timestamp is used to characterize the unified start-up time of each curtain device within the curtain group executing the control command.

[0026] Furthermore, the average Hall value of the curtain group is determined by the main control terminal based on the travel Hall values ​​reported by each curtain device within the curtain group. The travel Hall value refers to the Hall count value of the smart curtain as it travels from the start point to the end point of its full travel, for example, the Hall count value of the smart curtain as it travels from the highest point to the lowest point. The Hall count value is collected by the Hall sensors built into the curtain devices.

[0027] It should be noted that the Hall effect count value for one revolution of the motor in curtain equipment with different structures may be different; in addition, the Hall effect count value for the same length of curtain fabric will be different for curtains with different motor mechanism tube diameters.

[0028] It should be noted that, referring to Figure 2 , Figure 2 This system architecture diagram, provided in one embodiment of the present application, shows that the master control terminal can be a gateway device, router, border router, or a device designated in a wireless network (e.g., designated in the cloud or elected locally). For example, a curtain device can be designated as the master control terminal. Users can select to add curtain devices through the relevant interface of the client's APP. After recognizing the user's device addition command, the client sends the command to the cloud server. The device addition command includes the identifier of the master control terminal. The cloud server sends the device addition command to the corresponding master control terminal. After scanning and recognizing the curtain devices, the master control terminal obtains the device information corresponding to each curtain device and returns it to the cloud server. Optionally, the master control terminal and the curtain devices can communicate via WiFi, Bluetooth Thread, or Zigbee. The cloud server synchronizes the device information of the curtain devices to the client that initiated the operation. The client receives and displays the device information of the curtain devices sent by the cloud server, and the user can subsequently create curtain groups based on the curtain devices displayed on the client.

[0029] In this embodiment, the user initiates a flush control operation for the curtain group on the client. The client sends the user-initiated start command to the cloud server, which then sends the start command to the main control terminal. The main control terminal parses the start command. Optionally, the parameters of the start command may include information such as the curtain group identifier, the curtain device identifier, the reference speed, and the curtain opening / closing degree. Based on the parameters of the start command and the average Hall value of the curtain group associated with the curtain group identifier, the main control terminal generates a control command and sends it to each curtain device in the curtain group, for example, via broadcast or multicast. Each curtain device in the curtain group, upon receiving the control command from the main control terminal, parses the control command to obtain the command parameters.

[0030] Step S12: Based on the reference speed, the average Hall value of the curtain group, and the travel Hall value of the curtain device, perform path planning to obtain the target planned path; It should be noted that the target planning path includes the relationship between speed and time, as well as the relationship between displacement and time. Each curtain device is equipped with a predetermined operating curve. For example, if a gradual start-stop function is required, a three-stage speed change scheme is used, consisting of an acceleration-constant speed-deceleration target planning path.

[0031] In this embodiment, the uniform speed during the constant speed phase is calculated based on the reference speed, the average Hall value of the curtain assembly, and the Hall value of the curtain device itself during its stroke. The calculation formula is as follows:

[0032] Among them, H group V represents the average Hall effect value of the curtain group. ref H represents the reference speed. curtain Indicates the travel Hall value, v const It indicates a uniform velocity.

[0033] Furthermore, based on the average Hall value of the curtain group and the constant speed, the total running time of the device is calculated. In other embodiments, the user sets the curtain opening degree, and the total running time of the device is calculated based on the average Hall value of the curtain group, the curtain opening degree, and the constant speed, ensuring that the total running time of all devices in the group is the same. Then, within the total running time, assuming the acceleration phase is v1 with an acceleration time of t1, the deceleration phase is v3 with a deceleration time of t2, the specific relationships between speed and time in the acceleration, constant speed, and deceleration phases are constructed as follows:

[0034] Under normal circumstances, the acceleration and deceleration of the curtain are constant, and the acceleration time is also fixed (i.e., t1 and t2 are fixed). The relationship between velocity and time can be further derived as follows:

[0035] Where t3 represents the total runtime.

[0036] In addition, a graph showing the relationship between speed and time can be found here. Figure 3 , Figure 3 A graph showing the relationship between speed and time as provided in one embodiment of this application.

[0037] Furthermore, after calculating the relationship between velocity and time, the relationship between displacement and time can be calculated by combining it with the relationship between displacement and velocity, as follows:

[0038] in,

[0039] Where Hgroup represents the average Hall value of the curtain group, Vref represents the reference speed, Hcurtain represents the travel Hall value, and vconst represents the constant speed.

[0040] Step S13: Control the operation of the smart curtains according to the target planning path so that each smart curtain in the curtain group can run in parallel.

[0041] It should be noted that "aligned operation" does not mean that all curtains are physically in the same position. Rather, it means that all smart curtains in the group have the same relative opening and closing ratio at any given time, start synchronously, reach the user-specified target opening and closing degree at the same time, maintain visual alignment throughout, and finally stop at the same relative position.

[0042] In this embodiment, the smart curtains are controlled to start operation. During operation, the current actual Hall position and actual running speed are collected according to a preset cycle. The planned position and planned speed corresponding to the current time are retrieved from the target planned path. The position loop calculates the position deviation between the actual Hall position and the planned position, and sends a speed correction command to the speed loop according to the position deviation. The speed loop adjusts the motor speed in real time according to the speed correction command and the speed deviation between the actual running speed and the planned speed, and controls each curtain device to run in accordance with its own target planned path, so that each smart curtain starts synchronously, has a consistent relative opening and closing ratio throughout the process, and reaches the target opening and closing degree at the same time, ultimately achieving the parallel operation of each smart curtain in the curtain group.

[0043] In this embodiment, after creating a curtain group, the main control terminal calculates the average Hall value of the curtain group based on the travel Hall values ​​reported by each curtain device within the group. When each curtain device in the group receives a control command from the main control terminal, it combines the reference speed in the control command, the average Hall value of the curtain group, and its own travel Hall value to perform path planning, generate a target planned path, and control the operation of the smart curtains according to the target planned path. This effectively avoids alignment deviations caused by differences in the travel of individual curtains, and the curtain devices do not need to provide real-time status feedback to the main control terminal during operation, effectively improving the alignment control effect of the curtains.

[0044] In one feasible implementation, the operation of the smart curtains is controlled according to the target planning path to ensure that each smart curtain in the curtain group operates in parallel, including: Step S21: When the execution timestamp arrives, control the smart curtain to start running, and collect the actual Hall position of the smart curtain at the current time during the operation. It should be noted that the curtain device's clock configuration requires periodic timestamp calibration. The timestamp can be obtained from the main control terminal or directly requested from the cloud server. The command parameters also include an execution timestamp; if the execution timestamp is 0 or less than or equal to the current timestamp, the curtain device immediately executes the control process upon receiving the control command; if the execution timestamp is greater than the current timestamp, the curtain device executes the control command after the execution timestamp arrives, thus ensuring that all devices within the curtain group start synchronously according to the execution timestamp. During operation, the actual Hall position of the smart curtain at the current time is periodically collected according to a preset time cycle; that is, the actual Hall position at the current time point is collected through the built-in Hall sensor.

[0045] Step S22: Determine the planned position corresponding to the current time based on the relationship between displacement and time; In this embodiment, the running time is determined based on the current time and the start time. The curtain device then determines the planned position corresponding to the current time based on the relationship between its own displacement and time, according to the running time.

[0046] Step S23: Determine the position deviation based on the actual Hall position and the planned position; In this embodiment, the difference between the planned position and the actual Hall position is calculated to obtain the position deviation; optionally, the positive or negative sign of the position deviation represents the direction of deviation. A position deviation greater than 0 indicates that the actual Hall position is behind the planned position (the curtain is moving too slowly and has not reached the target position); a position deviation less than 0 indicates that the actual Hall position is ahead of the planned position (the curtain is moving too fast and has exceeded the target position); a position deviation equal to 0 indicates that the actual position and the planned position completely coincide, with no deviation.

[0047] Step S24: Based on the position deviation and the relationship between speed and time, determine the speed deviation, and control the operation of the smart curtains according to the speed deviation so that each smart curtain in the curtain group can run parallel.

[0048] In this embodiment, the target speed for the current time is determined by combining the relationship between speed and time. Based on the magnitude and direction of the positional deviation, the target speed for the current time point is adjusted. The speed deviation is calculated based on the corrected target speed and the actual current operating speed of the curtains. The power supply of the built-in motor is directly adjusted according to the magnitude and direction of the speed deviation, thereby controlling the motor speed to ensure that each time point reaches the designated position, achieving level operation of all curtains within the curtain group.

[0049] This embodiment controls the operation of the smart curtains according to the target planning path, ensuring that the curtains reach the designated position at each time point. This effectively avoids alignment deviations caused by differences in the travel of individual curtains, and the curtain equipment does not need to provide real-time status feedback to the main control terminal during operation, thus effectively improving the alignment control effect of the curtains.

[0050] In one feasible implementation, before parsing the command parameters in response to the control command sent by the master control terminal, the process further includes: Step S31: In response to the user's travel setting command, control the operation of the smart curtain to record the Hall count value of the smart curtain from the start of the full travel to the end of the full travel, and obtain the travel Hall value.

[0051] In this embodiment, the user can initiate a travel setting command via the client or remote control to drive the curtain to complete its full travel, for example, from the starting point of the full travel (such as the highest point of the curtain or the leftmost point of the curtain) to the ending point of the full travel (such as the lowest point of the curtain or the rightmost point of the curtain). The built-in Hall sensor begins to collect the pulse signal of the motor rotation in real time to record the Hall count value of the smart curtain from the starting point to the ending point of the full travel, and uses the Hall count value as the travel Hall value.

[0052] In one feasible implementation, before parsing the command parameters in response to the control command sent by the master control terminal, the process further includes: Step S41: In response to the curtain group creation command sent by the master control terminal, the stored travel Hall values ​​are reported to the master control terminal so that the master control terminal can calculate the average Hall value of the curtain group based on the travel Hall values ​​of each curtain device in the curtain group.

[0053] In this embodiment, the user can select curtain devices in the client to initiate a curtain group creation command. The curtain group creation command may include information such as a curtain group identifier and curtain device identifier. The curtain group identifier includes the curtain group's name and ID. The curtain group creation command is sent to the main control terminal via the cloud server, and then the main control terminal sends the curtain group creation command to the curtain devices corresponding to each curtain device identifier. (Refer to...) Figure 4 , Figure 4 This diagram illustrates a curtain device reporting its travel Hall effect value to a main control terminal according to an embodiment of this application. After receiving a command, the curtain device reports its stored travel Hall effect value to the main control terminal, which then averages the travel Hall effect values ​​of each curtain device in the curtain group to obtain the average Hall effect value of the curtain group. In one embodiment, the main control terminal can associate the average Hall effect value of the curtain group with a curtain group identifier for storage.

[0054] This embodiment controls the operation of smart curtains to record Hall effect counts from the start to the end of the entire travel path, obtaining the travel Hall value. When creating a curtain group, the travel Hall values ​​stored in the curtain devices are reported to the main control terminal, so that the main control terminal can calculate the average Hall value of the curtain group based on the travel Hall values ​​of each curtain device in the curtain group. Subsequently, each curtain device in the curtain group uses the average Hall value of the curtain group as a reference for path planning, and adjusts its own speed curve and Hall value path curve proportionally, thereby offsetting the differences between curtains with different pipe diameters.

[0055] In one feasible implementation, this application also provides a curtain flush control method, applied to the main control terminal, referring to... Figure 5 , Figure 5 The flowchart provided in Embodiment 2 of the curtain flush control method of this application is a schematic diagram.

[0056] Step S51: In response to the start command sent by the cloud server, the curtain group identifier of the curtain group is parsed and obtained; Step S52: Generate a control command based on the start command and the average Hall value of the curtain group; Step S53: The control command is sent to the curtain device associated with the curtain group identifier, so that the curtain device can parse the command command to obtain command parameters, wherein the command parameters include a reference speed and the average Hall value of the curtain group; based on the reference speed, the average Hall value of the curtain group and the travel Hall value of the curtain device, path planning is performed to obtain a target planned path; based on the target planned path, the operation of the smart curtains is controlled so that each smart curtain corresponding to the curtain group can run in parallel.

[0057] In this embodiment, the user initiates a flush control operation for the curtain group on the client. The client sends the user-initiated start command to the cloud server, which then sends the start command to the main control terminal. The main control terminal parses the start command. Optionally, the parameters of the start command may include information such as the curtain group identifier, the curtain device identifier, the reference speed, and the curtain opening / closing degree. Based on the parameters of the start command and the average Hall value of the curtain group associated with the curtain group identifier, the main control terminal generates a control command and sends it to each curtain device in the curtain group, for example, by broadcasting or multicasting the command.

[0058] After receiving a control command from the main control terminal, each curtain device in the curtain group parses the control command to obtain the command parameters. Then, based on these command parameters, path planning is performed to obtain the target planned path. The target planned path includes the relationship between speed and time, and the relationship between displacement and time. For example, the relationship between speed and time is constructed based on information such as the reference speed, the average Hall value of the curtain group, and the travel Hall value of the curtain device; the relationship between displacement and time is also constructed based on the relationship between speed and time. Furthermore, combining the relationships between speed and time and displacement and time, each curtain device is controlled to run along its own target planned path, ensuring that all smart curtains start synchronously, maintain a consistent relative opening and closing ratio throughout the entire process, and simultaneously reach the target opening and closing degree. Ultimately, this achieves level operation of all smart curtains corresponding to the curtain group. The specific control flow of the curtain devices in this embodiment is the same as the control flow of steps S11 to S13, and will not be repeated here.

[0059] This embodiment calculates the average Hall value of the curtain group after its creation, based on the travel Hall values ​​reported by each curtain device within the group. Then, combining user commands with this average Hall value, a control command is generated. This command controls each curtain device within the group to perform path planning, using the reference speed and average Hall value from the control command to generate a target path. The operation of the smart curtains is then controlled according to this target path. This effectively avoids alignment deviations caused by differences in the travel of individual curtains, and the curtain devices do not need to provide real-time status feedback to the control terminal during operation, significantly improving the alignment control effect.

[0060] In one feasible implementation, before parsing and obtaining the curtain group identifier in response to a control command sent by the cloud server, the method further includes: Step S61: In response to the curtain group creation command sent by the cloud server, the identifiers of each curtain device and the curtain group identifier of the curtain group are parsed to obtain the identifiers of each curtain device and the curtain group. Step S62: Send the curtain group creation command to the curtain device corresponding to each curtain device identifier, and receive the travel Hall value reported by each curtain device; Step S63: Average the travel Hall values ​​of each curtain device in the curtain group to obtain the average Hall value of the curtain group. Step S64: Associate and store the curtain group identifier and the average Hall value of the curtain group.

[0061] In this embodiment, the user can select curtain devices in the client to initiate a curtain group creation command. The curtain group creation command may include information such as curtain group identifier and curtain device identifier. The curtain group identifier includes the name and ID of the curtain group. Each curtain device corresponding to one of these identifiers forms a curtain group. The curtain group creation command is sent to the main control terminal via a cloud server, and the main control terminal then sends the command to the curtain devices corresponding to each curtain device identifier. After receiving the command, the curtain devices report their stored travel Hall effect values ​​to the main control terminal. The main control terminal averages the travel Hall effect values ​​of each curtain device in the curtain group to obtain the average Hall effect value of the curtain group. For example, if a curtain group has three curtains with travel Hall effect counts of 26600, 28000, and 29400 respectively, then the average Hall effect value of the curtain group is (26600 + 28000 + 29400) / 3 = 28000.

[0062] Furthermore, the average Hall value of the curtain group is associated with and stored in relation to the curtain group identifier.

[0063] In this embodiment, the main control terminal calculates the average Hall value of the curtain group based on the travel Hall value of each curtain device in the curtain group. Subsequently, each curtain device in the curtain group performs path planning based on the average Hall value of the curtain group, and adjusts its own speed curve and Hall value path curve proportionally, thereby offsetting the differences between curtains with different pipe diameters.

[0064] In one feasible implementation, this application also provides a curtain flush control method, applied to the main control terminal, referring to... Figure 6 , Figure 6 This is a flowchart illustrating Embodiment 3 of the curtain flush control method of this application.

[0065] Step S71: In response to the user's start command, the start command is sent to the main control terminal via the cloud server, so that the main control terminal can parse and obtain the curtain group identifier of the curtain group; a control command is generated based on the start command and the average Hall value of the curtain group; the control command is sent to the curtain device associated with the curtain group identifier; the curtain device parses and obtains the command parameters based on the control command, wherein the command parameters include a reference speed and the average Hall value of the curtain group; path planning is performed based on the reference speed, the average Hall value of the curtain group, and the travel Hall value of the curtain device to obtain a target planned path; the operation of the smart curtains is controlled according to the target planned path to ensure that each smart curtain corresponding to the curtain group operates in parallel.

[0066] In this embodiment, the user initiates a flush control operation for the curtain group on the client. The client sends the user-initiated start command to the cloud server, which then sends the start command to the main control terminal. The main control terminal parses the start command. Optionally, the parameters of the start command may include information such as the curtain group identifier, the curtain device identifier, the reference speed, and the curtain opening / closing degree. Based on the parameters of the start command and the average Hall value of the curtain group associated with the curtain group identifier, the main control terminal generates a control command and sends it to each curtain device in the curtain group, for example, by broadcasting or multicasting the command.

[0067] After receiving a control command from the main control terminal, each curtain device in the curtain group parses the command to obtain its command parameters. Based on these parameters, path planning is then performed to obtain the target planned path. The target planned path includes the relationship between speed and time, and the relationship between displacement and time. For example, the relationship between speed and time is constructed based on information such as the reference speed, the average Hall value of the curtain group, and the travel Hall values ​​stored by the curtain device itself. The average Hall value of the curtain group is pre-determined by the main control terminal based on the travel Hall values ​​reported by the curtain devices in the curtain group. The relationship between displacement and time is then constructed based on the relationship between speed and time. Furthermore, by combining the relationships between speed and time and displacement and time, each curtain device is controlled to run along its own target planned path, ensuring that all smart curtains start synchronously, maintain a consistent relative opening and closing ratio throughout the entire process, and simultaneously reach the target opening and closing degree. Ultimately, this achieves level operation of all smart curtains corresponding to the curtain group. The specific control flow of the curtain devices in this embodiment is the same as the control flow of steps S11 to S13, and will not be repeated here.

[0068] This embodiment can effectively avoid alignment deviations caused by differences in the travel of individual curtains, and the curtain equipment does not need to provide real-time status information to the main control terminal during operation, thus effectively improving the effect of curtain alignment control.

[0069] In one feasible implementation, before sending the start command to the main control terminal via the cloud server in response to the user's start command, the method further includes: in response to the user's curtain group creation command, sending the curtain group creation command to the main control terminal via the cloud server, so that the main control terminal can parse and obtain the identifiers of each curtain device and the curtain group identifier of the curtain group; sending the curtain group creation command to the curtain devices corresponding to each of the curtain device identifiers; and averaging the travel Hall values ​​reported by each curtain device in the curtain group to obtain the average Hall value of the curtain group.

[0070] In this embodiment, the user can select curtain devices in the client to initiate a curtain group creation command. The curtain group creation command may include information such as a curtain group identifier and curtain device identifiers. The curtain group identifier includes the name and ID of the curtain group, and the curtain devices corresponding to each of these identifiers form a curtain group. The curtain group creation command is sent to the main control terminal via a cloud server, and the main control terminal then sends the command to the curtain devices corresponding to each curtain device identifier. After receiving the command, the curtain devices report their stored travel Hall values ​​to the main control terminal. The main control terminal averages the travel Hall values ​​of each curtain device in the curtain group to obtain the average Hall value of the curtain group. Optionally, the main control terminal can associate and store the average Hall value of the curtain group with the curtain group identifier.

[0071] In this embodiment, by selecting a curtain device in the client to initiate a curtain group creation command, the main control terminal calculates the average Hall value of the curtain group based on the travel Hall values ​​reported by each curtain device in the curtain group. Subsequently, each curtain device in the curtain group performs path planning based on the average Hall value of the curtain group, and adjusts its own speed curve and Hall value path curve proportionally, thereby offsetting the differences between curtains with different pipe diameters.

Based on the reference speed, the average Hall value of the curtain group, and the travel Hall values ​​of the curtain devices, path planning is performed to obtain a target planned path.
