Description

Technical Field

[0001] This application relates to the field of gesture control technology for air conditioners, such as a method, apparatus, and smart air conditioner for controlling an air conditioner based on electromyography signals. Background Technology

[0002] Currently, some smart air conditioners use image acquisition devices to capture images of users' hands and recognize the user's gestures within those images. Based on this recognition, the air conditioner can be controlled, thus improving the user experience. However, this control method is relatively area-dependent; for example, the user needs to make the corresponding gesture within the image acquisition area of ​​the device, which reduces the ease of control to some extent. To improve ease of control, an electromyography (EMG) wristband can be used to collect the user's electromyographic signals from their hand. These signals can then be converted into hand gestures, which can be mapped to control commands for the air conditioner. Finally, these commands can be used to control the air conditioner.

[0003] In the process of implementing the embodiments of this application, at least the following problems were found in the related technology:

[0004] In daily life, users' hand movements are diverse. When electromyography (EMG) bracelets collect EMG signals and convert them into hand gestures, random hand gestures in daily life can easily be misinterpreted as control signals for air conditioners, leading to malfunctions of the air conditioner.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This application provides a method, apparatus, and smart air conditioner for controlling an air conditioner based on electromyography (EMG) signals, in order to reduce the occurrence of gesture misjudgment during the process of controlling the air conditioner through EMG signals.

[0008] In some embodiments, the method for controlling an air conditioner based on electromyographic signals includes: determining the current command level corresponding to the current operating state of the air conditioner according to the correspondence between operating state and command level; the operating state is divided based on the sequence of actions of the air conditioner in the air conditioner control habit; obtaining the current gesture action represented by the current electromyographic gesture signal; determining the current control command according to the current gesture action and the current command level; and controlling the air conditioner according to the current control command.

[0009] Optionally, determining the current command level corresponding to the current operating state of the air conditioner includes: determining the current command level as level one when the current operating state is off; determining the current command level as level two when the current operating state is on for a duration less than or equal to a first set duration; and determining the current command level as level three when the current operating state is on for a duration greater than the first set duration.

[0010] Optionally, the current control instruction is determined based on the current gesture and the current instruction level, including: obtaining the current control instruction set that has execution permission at the current instruction level; if the control instruction corresponding to the current gesture belongs to the current control instruction set, then the control instruction corresponding to the current gesture is taken as the current control instruction; if the control instruction corresponding to the current gesture does not belong to the current control instruction set, then the current control instruction is determined to be empty.

[0011] Optionally, obtaining the current control instruction set that the current instruction level has execution permission includes: when the current instruction level is level 1, having the permission to execute the control instruction set corresponding to level 1, but not having the permission to execute the control instruction sets corresponding to level 2 and level 3; when the current instruction level is level 2, having the permission to execute the control instruction sets corresponding to level 1 and level 2, but not having the permission to execute the control instruction set corresponding to level 3; and when the current instruction level is level 3, having the permission to execute the control instruction sets corresponding to level 1, level 2, and level 3.

[0012] Optionally, obtaining the current gesture action represented by the current electromyographic gesture signal includes: obtaining a first number of consecutive empty historical control commands up to the current time; if the first number is less than or equal to a set fault tolerance threshold, then obtaining the current gesture action represented by the current electromyographic gesture signal.

[0013] Optionally, obtaining the current gesture action represented by the current electromyographic gesture signal further includes: if the first quantity is greater than a set fault tolerance threshold, then waiting for a second set time before obtaining the gesture instruction represented by the electromyographic gesture signal.

[0014] Optionally, obtaining the first number of consecutively empty historical control commands up to the current time includes: obtaining the first number of consecutively empty historical control commands within a third set time period before the current time.

[0015] In some embodiments, the device for controlling an air conditioner based on electromyographic signals includes a first determining module, an obtaining module, a second determining module, and a control module. The first determining module is used to determine the current command level corresponding to the current operating state of the air conditioner according to the correspondence between the operating state and the command level. The operating state is divided based on the sequential action order of the air conditioner in the air conditioner control habit. The obtaining module is used to obtain the current gesture action represented by the current electromyographic gesture signal. The second determining module is used to determine the current control command according to the current gesture action and the current command level. The control module is used to control the air conditioner according to the current control command.

[0016] In some embodiments, the apparatus for controlling an air conditioner based on electromyography (EMG) signals includes a processor and a memory storing program instructions, the processor being configured to execute the method for controlling an air conditioner based on EMG signals provided in the foregoing embodiments when executing the program instructions.

[0018] The method, apparatus, and intelligent air conditioner for controlling air conditioning based on electromyography signals provided in this application can achieve the following technical effects:

[0019] The process begins by determining the current control command level corresponding to the air conditioner's current operating state. This means the current control command level corresponds to the current operating state. Further, the current control command is determined based on the current gesture and the current command level. This means the current control command must correspond to the current operating state; therefore, control commands that do not correspond to the current operating state will not be identified as current control commands. In other words, not all random gestures from the user are identified as current control commands; only those corresponding to the current operating state are identified. This reduces the probability of random gestures being misidentified as current control commands, minimizing the occurrence of gesture misjudgments.

[0034] Figure 1 This is a flowchart illustrating a method for controlling an air conditioner based on electromyography (EMG) signals, as provided in an embodiment of this application. This method can be implemented in the controller of the air conditioner; it can also be implemented in the controller of the EMG acquisition device; and when both the EMG acquisition device and the air conditioner are communicatively connected to a server, the method can also be implemented in the server.

[0035] Combination Figure 1 As shown, the method for controlling air conditioning based on electromyography signals includes:

[0036] S101. Determine the current command level corresponding to the current operating state of the air conditioner based on the correspondence between the operating state and the command level.

[0037] The operating status of an air conditioner is determined based on the sequence of actions of the air conditioner in the air conditioner control habits. These control habits can be the current user's control habits, or they can be the control habits of most people.

[0038] Each instruction level corresponds to a control instruction set, which is a collection of control instructions for the air conditioner. Each control instruction set includes one or more control instructions.

[0039] Air conditioner control commands include, but are not limited to: start-up command, cooling command, heating command, fan speed command, airflow direction command, air wash command, and fresh air command.

[0040] Based on this, the control instruction set corresponding to the first-level instruction level may include the power-on instruction; the control instruction set corresponding to the second-level instruction level may include the cooling instruction and the heating instruction; and the control instruction set corresponding to the third-level instruction level may include the fan speed instruction, the air blowing direction instruction, the air washing instruction, and the fresh air instruction.

[0041] The above-described method of classifying control commands by command level is merely an illustrative example. Those skilled in the art can classify the actual control commands of the air conditioner by command level according to the above approach.

[0042] The correspondence between operating status and instruction level can be stored in a database. After obtaining the current operating status of the air conditioner, the current instruction level corresponding to the current operating status can be obtained by querying the database.

[0043] The operating status of the air conditioner may include the off state, the on state with an on time less than or equal to a first set time, and the on state with an on time greater than the first set time.

[0044] Based on this, the current command level corresponding to the current operating state of the air conditioner can be determined as follows: when the current operating state is off, the current command level is determined as Level 1; when the current operating state is on for a duration less than or equal to a first set duration, the current command level is determined as Level 2; when the current operating state is on for a duration greater than the first set duration, the current command level is determined as Level 3.

[0045] The initial setting time is related to the user's air conditioning usage habits. For example, if the user is used to quickly adjusting the air conditioning settings, the initial setting time will be shorter; if the user is used to slowly adjusting the air conditioning settings, the initial setting time will be longer.

[0046] A user's air conditioning usage habits can be those of a single user or those of multiple users.

[0047] If a user's air conditioning usage habits are consistent with those of a single user, the user can pre-set the first set duration. Furthermore, after the air conditioner is turned on, the system can calculate the first duration required for the user to set the relevant parameters of the air conditioner. The longer the first duration, the longer the first set duration; the shorter the first duration, the shorter the first set duration.

[0048] In cases where multiple users share the habit of using the air conditioner, after the air conditioner is turned on, the second duration required for multiple users to set the relevant parameters of the air conditioner can be calculated. This second duration can be the average duration. The longer the second duration, the longer the first setting duration; the shorter the second duration, the shorter the first setting duration.

[0049] In this way, the current instruction level can be obtained.

[0050] S102. Obtain the current gesture action represented by the current electromyographic gesture signal.

[0051] Users can wear electromyography (EMG) acquisition devices, such as EMG wristbands. Different user gestures result in different EMG hand signals collected by the EMG acquisition device, allowing the user's hand movements to be determined.

[0052] S103. Determine the current control command based on the current gesture and the current command level.

[0053] There is a corresponding relationship between the current gesture, the current command level, and the current control command.

[0054] S104. Control the air conditioner according to the current control command.

[0055] The process begins by determining the current control command level corresponding to the air conditioner's current operating state. This means the current control command level corresponds to the current operating state. Further, the current control command is determined based on the current gesture and the current command level. This means the current control command must correspond to the current operating state; therefore, control commands that do not correspond to the current operating state will not be identified as current control commands. In other words, not all random gestures from the user are identified as current control commands; only those corresponding to the current operating state are identified. This reduces the probability of random gestures being misidentified as current control commands, minimizing the occurrence of gesture misjudgments.

[0056] Figure 2 This is a flowchart illustrating a method for controlling an air conditioner based on electromyography (EMG) signals, as provided in an embodiment of this application. This method can be implemented in the controller of the air conditioner; it can also be implemented in the controller of the EMG acquisition device; and when both the EMG acquisition device and the air conditioner are communicatively connected to a server, the method can also be implemented in the server.

[0057] Combination Figure 2 As shown, the method for controlling air conditioning based on electromyography signals includes:

[0058] S201. Determine the current command level corresponding to the current operating state of the air conditioner based on the correspondence between the operating state and the command level.

[0059] S202. Obtain the current gesture action represented by the current electromyographic gesture signal.

[0060] S203. Obtain the current control instruction set that has execution permission at the current instruction level.

[0061] Each instruction level corresponds to a set of control instructions, and different instruction levels have different instruction execution permissions.

[0062] Each instruction level has the right to execute its corresponding control instruction set, as well as the right to execute the control instruction sets of other instruction levels with higher priority.

[0063] That is, the current control instruction set in this application embodiment includes the control instruction set corresponding to the current instruction level, and the control instruction sets corresponding to other instruction levels with higher priority than the current instruction level.

[0064] For example, the control instruction set corresponding to the first-level instruction level may include the power-on instruction; the control instruction set corresponding to the second-level instruction level may include the cooling instruction and the heating instruction; and the control instruction set corresponding to the third-level instruction level may include the fan speed instruction, the air blowing direction instruction, the air washing instruction, and the fresh air instruction.

[0065] Specifically, obtaining the current control instruction set that has execution permission at the current instruction level may include:

[0066] When the current instruction level is Level 1, it has the authority to execute the control instruction set corresponding to Level 1, but does not have the authority to execute the control instruction sets corresponding to Level 2 and Level 3.

[0067] When the current instruction level is level 2, it has the authority to execute the control instruction sets corresponding to level 1 and level 2, but does not have the authority to execute the control instruction sets corresponding to level 3.

[0068] When the current instruction level is level 3, it has the authority to execute the control instruction sets corresponding to level 1, level 2, and level 3 instructions;

[0069] Among them, the priority of Level 1 instruction is higher than that of Level 2 instruction, and the priority of Level 2 instruction is higher than that of Level 3 instruction.

[0070] For example, when the current command level is Level 1, the current control command set may include a power-on command; when the current command level is Level 2, the current control command set may include a cooling command, a heating command, and a power-on command; when the current command level is Level 3, the current control command set may include a fan speed command, a fan direction command, an air wash command, a fresh air command, a cooling command, a heating command, and a power-on command.

[0071] S204. If the control instruction corresponding to the current gesture belongs to the current control instruction set, then the control instruction corresponding to the current gesture shall be used as the current control instruction.

[0072] There is a correspondence between gestures and control commands. Based on this correspondence, the control command corresponding to the current gesture can be obtained.

[0073] S205. Control the air conditioner according to the current control command.

[0074] S206. If the control instruction corresponding to the current gesture action does not belong to the current control instruction set, then the current control instruction is determined to be empty.

[0075] The current control command is empty, indicating that the air conditioner does not respond to the current electromyographic gesture signal, and then S202 is re-executed. This embodiment of the application only illustrates the example of re-executing S202. In specific applications, S201 can also be re-executed when the current command is empty.

[0076] The current control instruction set includes the control instruction set corresponding to the current instruction level, as well as the control instruction sets corresponding to other instruction levels with higher priority than the current instruction level. This reduces the occurrence of gesture misjudgment and makes the method of controlling air conditioners based on electromyography signals more flexible.

[0077] Figure 3 This is a flowchart illustrating a method for controlling an air conditioner based on electromyography (EMG) signals, as provided in an embodiment of this application. This method can be implemented in the controller of the air conditioner; it can also be implemented in the controller of the EMG acquisition device; and when both the EMG acquisition device and the air conditioner are communicatively connected to a server, the method can also be implemented in the server.

[0078] Combination Figure 3 As shown, the method for controlling air conditioning based on electromyography signals includes:

[0079] S301. Determine the current command level corresponding to the current operating state of the air conditioner based on the correspondence between the operating state and the command level.

[0080] S302. Obtain the first number of consecutive empty historical control instructions up to the current time.

[0081] For example, up to the current moment, the obtained historical control instructions, in chronological order, are: null instruction, null instruction, non-null instruction, null instruction, null instruction, null instruction, null instruction. In this case, the first quantity is 3.

[0082] Optionally, obtaining the first number of consecutively empty historical control commands up to the current time includes: obtaining the first number of consecutively empty historical control commands within a third set time period before the current time.

[0083] The third set duration can be a recognition time window for recognizing electromyographic gesture signals. Electromyographic gesture signals obtained within the recognition time window are recognized, while those obtained outside the recognition time window are not recognized, or, outside the recognition time window, electromyographic gesture signals are not collected.

[0084] The third set duration is inversely correlated with the accuracy of the user's gesture actions, and positively correlated with the misjudgment rate of gesture misjudgment.

[0085] When a user needs to control the air conditioner, the higher the accuracy of the user's gesture, the shorter the third setting time; the lower the accuracy of the user's gesture, the longer the third setting time. The higher the requirement to reduce the occurrence of gesture misjudgment, that is, the lower the misjudgment rate of the demand for gesture misjudgment, the shorter the third setting time; the higher the misjudgment rate of the demand for gesture misjudgment, the longer the third setting time.

[0086] Those skilled in the art can determine a third set duration that conforms to the actual situation based on the specific meaning of the third set duration.

[0087] S303. If the first quantity is less than or equal to the set fault tolerance threshold, the current gesture action represented by the current electromyographic gesture signal is obtained.

[0088] The higher the fault tolerance threshold, the easier it is for the air conditioner to misinterpret gestures and malfunction, resulting in a higher misinterpretation rate. Conversely, the lower the fault tolerance threshold, the less likely the air conditioner will misinterpret gestures and malfunction, resulting in a lower misinterpretation rate, but it may lead to situations where users are unable to control the air conditioner.

[0089] Those skilled in the art can determine the appropriate fault tolerance threshold based on its specific meaning.

[0090] S304. Obtain the current control instruction set that has execution privileges at the current instruction level.

[0091] S305. If the control instruction corresponding to the current gesture belongs to the current control instruction set, then the control instruction corresponding to the current gesture shall be used as the current control instruction.

[0092] S306. Control the air conditioner according to the current control command.

[0093] S307. If the control instruction corresponding to the current gesture action does not belong to the current control instruction set, then the current control instruction is determined to be empty.

[0094] S308, Increment the first number of consecutive empty historical control instructions by one.

[0095] Then S302 is re-executed. This embodiment of the application only uses the re-execution of S302 as an example for illustrative purposes. In specific applications, S301 can also be re-executed when the current instruction is empty.

[0096] By adopting the above technical solution, the misjudgment rate of gesture misjudgment can be adjusted by adjusting the set fault tolerance threshold.

[0097] Figure 4This is a flowchart illustrating a method for controlling an air conditioner based on electromyography (EMG) signals, as provided in an embodiment of this application. This method can be implemented in the controller of the air conditioner; it can also be implemented in the controller of the EMG acquisition device; and when both the EMG acquisition device and the air conditioner are communicatively connected to a server, the method can also be implemented in the server.

[0098] Combination Figure 4 As shown, the method for controlling air conditioning based on electromyography signals includes:

[0099] S401. Determine the current command level corresponding to the current operating status of the air conditioner based on the correspondence between the operating status and the command level.

[0100] S402. Obtain the first number of consecutive empty historical control instructions up to the current time.

[0101] S403. If the first quantity is less than or equal to the set fault tolerance threshold, the current gesture action represented by the current electromyographic gesture signal is obtained.

[0102] S404: Obtain the current control instruction set that has the execution permission at the current instruction level.

[0103] S405. If the control instruction corresponding to the current gesture belongs to the current control instruction set, then the control instruction corresponding to the current gesture shall be used as the current control instruction.

[0104] S406. Control the air conditioner according to the current control command.

[0105] S407. If the control instruction corresponding to the current gesture action does not belong to the current control instruction set, then the current control instruction is determined to be empty.

[0106] S408: Increment the first number of consecutive empty historical control instructions by one.

[0107] S409. If the first quantity is greater than the set fault tolerance threshold, then wait for the second set time before executing S402 to obtain the gesture command represented by the electromyographic gesture signal.

[0108] A longer second set duration results in a lower misjudgment rate for gesture misinterpretation, but also a longer period during which the user cannot control the air conditioner. Conversely, a shorter second set duration results in a longer period during which the user can control the air conditioner, but also a higher misjudgment rate for gesture misinterpretation. Therefore, those skilled in the art can determine a second set duration that suits the actual situation to balance the misjudgment rate of gesture misinterpretation with the duration during which the user cannot control the air conditioner, thereby improving the user experience.

[0109] Furthermore, if in S402 the operation is to obtain the first number of consecutive empty historical control instructions up to the current time, then in S409, the operation also includes clearing the historical control instructions.

[0110] If in S402 the following is executed: "obtain the first number of consecutive empty historical control commands within a third set time period before the current time", then in S409, clearing historical control commands may or may not include situational historical control commands.

[0111] Without clearing historical control commands, if the second set duration is shorter than the third set duration, it can also help reduce the misjudgment rate of gesture misjudgment.
