Description

Technical Field

[0001] The present invention relates to the technical field of smart home, and more particularly, to a method for unified control of cross-brand smart appliances for a smart home ecosystem. Background Art

[0002] With the rapid development of Internet of Things technology, smart home ecosystems have gradually entered people's lives. Smart home devices cover multiple fields such as smart lighting, smart home appliances, and smart security, bringing users a more convenient, comfortable, and intelligent living experience. Smart home devices of different brands, with their unique functions and designs, meet the diverse needs of users.

[0003] In a smart home ecosystem, unified control of cross-brand smart appliances has become the key to enhancing the user experience. Users hope to centrally control different brands and types of smart appliances in their homes through a unified control terminal (such as a smart speaker, a smartphone APP, etc.) to achieve more convenient operations. However, different smart home devices have significantly different abilities to understand instructions. Most smart home devices can only understand instructions in specific formats and semantics.

[0004] Taking voice control as an example, when a user issues a control instruction to a unified control device through voice, the unified control device first needs to parse the voice to obtain the corresponding control information. However, due to the differences in instruction understanding among smart home devices of different brands and types, if the unified control device directly sends the control information parsed from the voice to the smart home device, it is very likely that the smart home device will not be able to understand these instructions, resulting in control failure. For example, when a user issues a voice instruction "Dim the lights in the living room a bit" to a smart speaker, after the smart speaker, as the unified control device, parses the control information and sends it to a certain brand of smart lighting fixture, the fixture may only recognize instructions in a specific format such as "Reduce the living room light brightness to 50%", thus being unable to execute the user's operation, seriously affecting the user's control experience.

[0005] In order to achieve effective unified control of cross-brand smart appliances in a smart home ecosystem and enhance the user's control experience, there is an urgent need for a method that can solve the problem of different device instruction understanding differences, break down the barriers between brands and devices, and achieve seamless collaborative operation of smart home devices. Summary of the Invention

[0013] Optionally, the method further includes: the unified management device discovers the intelligent appliance by scanning a specific broadcast packet, obtains a pairing code by communicating with the official website network of the corresponding intelligent appliance or receiving information input by the user, and uses the pairing code to establish a connection with the corresponding intelligent appliance to access the corresponding intelligent appliance into the smart home ecosystem.

[0020] Figure 2 It is a schematic diagram of the scenario where a user controls various smart appliances by voice through a unified control device in an embodiment of the present invention. Detailed implementation manners

[0021] The following specific embodiments illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0022] In addition, the technical features involved in different implementation manners of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] Regarding the above - mentioned technical problems, as Figure 1 、 Figure 2 shown, an embodiment of the present invention discloses a method for unified control of cross - brand smart appliances for the smart home ecosystem, which is applied to a unified control device. The method includes the following steps: Step 1: Generate a set of voice control information at a set period, and forward each first voice control information in the set of voice control information to the corresponding smart appliance.

[0024] The unified control device (such as a smart speaker, a smartphone APP, etc.) will generate a series of sets of voice control information according to a pre - set time period (such as every month). This set contains various voice control information with different semantic expressions, which are control instructions for different functions of various smart appliances. For example, for smart lights, there may be different voice control information such as "Turn on the living room light" and "Adjust the brightness of the bedroom light to 80%"; for smart air conditioners, there may be "Set the air conditioner temperature to 25 degrees", "Turn on the air - conditioning cooling mode", "I feel a bit hot", etc. These voice control information include both specific control requirements and general or vague control requirements. Since the semantic understanding capabilities of different brands and types of smart home devices are different, these directly forwarded voice control information may not be well understood and executed.

[0025] Send each piece of voice control information in the generated set of voice control information to the corresponding smart appliance. For example, send the instruction to control the lamp to the corresponding lamp device, and send the instruction to control the air conditioner to the corresponding air conditioner device. With such settings, it is possible to test the understanding and response capabilities of different smart appliances to different instructions by sending diverse voice control information to them.

[0026] Step 2: Monitor the response information of the corresponding smart appliance to the first voice control information, and evaluate the first semantic understanding ability level of the corresponding smart appliance based on the response information.

[0027] After sending out the first voice control information, the unified management and control device continuously monitors the response situations returned by each smart appliance. These response information include whether the smart appliance has successfully executed the instruction, what the execution result is, and whether an error prompt is returned, etc. For example, if the instruction "Adjust the brightness of the living room lamp to 80%" is sent, the smart appliance may return a confirmation message indicating that the brightness has been successfully adjusted, or return an error message indicating that the instruction cannot be executed.

[0028] Based on the collected response information, the unified management and control device will evaluate the semantic understanding ability of each smart appliance and divide it into corresponding levels. For example, if a smart appliance can accurately understand and execute various voice control information with different formats and semantics, then its first semantic understanding ability level may be rated as relatively high; on the contrary, if a smart appliance can only understand a few specific formats of instructions and cannot respond to other instructions, then its first semantic understanding ability level will be relatively low.

[0029] It should be noted that the semantic understanding ability level can be divided into three levels: low, medium, and high, or it can be multiple levels represented by numbers 1 - 10, etc. The present invention does not limit this.

[0030] Step 3: Receive the first voice control instruction input by the user, parse the second voice control information and the target smart appliance to be controlled from the first voice control instruction, and generate the third voice control information according to the first semantic understanding ability level of the target smart appliance.

[0031] When the user issues a control instruction to the unified management and control device by voice, the unified management and control device first recognizes and parses the input voice of the user. Through voice recognition technology, the voice is converted into text information, and then further analyzed to obtain the specific control content, that is, the second voice control information, such as "The bedroom is too stuffy, turn on the fan", and the target smart appliance to be controlled, such as the smart fan in the bedroom.

[0032] According to the first semantic understanding ability level of the target intelligent appliance obtained from the previous evaluation, the parsed second voice control information is converted and adjusted to generate the third voice control information in a format and semantics that the target intelligent appliance can understand. For example, if the first semantic understanding ability level of the target intelligent appliance is relatively low and it can only understand relatively precise and specific format instructions, then the unified management device will convert the relatively vague first voice control instruction of the user (such as "turn up the fan a bit") into a precise instruction that the intelligent appliance can understand (such as "adjust the bedroom fan speed to gear 3").

[0033] Step Four: Forward the third voice control information to the target intelligent appliance for execution.

[0034] Send the generated third voice control information suitable for the semantic understanding ability of the target intelligent appliance to the target intelligent appliance, allowing it to perform corresponding operations according to the instructions, thereby achieving effective control of the target intelligent appliance, enhancing the user's control experience, and solving the problem of different devices having different understandings of instructions.

[0035] The above unified management solution for cross-brand intelligent appliances in the smart home ecosystem accurately evaluates the semantic understanding ability levels of each intelligent appliance by sending diverse voice control information to the intelligent appliances at set intervals and monitoring the responses. On this basis, when receiving a user's voice control instruction, it can convert the user instruction into a format that it can understand according to the semantic understanding ability level of the target intelligent appliance, generate the adapted voice control information and forward it for execution, effectively solving the problem of different brands and different types of smart home devices having different instruction understanding abilities, avoiding control failures, achieving effective unified management of cross-brand intelligent appliances, significantly enhancing the user's control experience of smart home devices, and promoting seamless collaborative work of smart home devices.

[0036] Optionally, generating the voice control information set according to the set period includes: determining multiple stored second semantic understanding ability levels associated with each intelligent appliance, determining the set period according to each of the second semantic understanding ability levels; collecting the second voice control instructions of the user for each intelligent appliance within the set period, and randomly selecting a part of the third voice control instructions and a part of the fourth voice control instructions therefrom, performing semantic fuzzification rewriting on the third voice control instructions to obtain the fifth voice control instructions; integrating the fifth voice control instructions and the fourth voice control instructions into the voice control information set.

[0037] In this embodiment, the unified management and control device stores multiple second semantic understanding ability levels associated with each intelligent appliance it determines, and these second semantic understanding ability levels are all obtained by the unified management and control device in previous evaluations. The higher the level, the richer and more flexible the instruction formats and semantics that the intelligent appliance can understand; the lower the level, the more limited its understanding ability, and it can only recognize instructions with specific formats and semantics.

[0038] The set period has a dynamic change relationship with the second semantic understanding ability level. Multiple second semantic understanding ability levels can be used to analyze the change situation of the semantic understanding ability of the intelligent appliance, and then match different set periods for it. Based on this set period, the frequency of re-evaluation that should be adopted can be determined.

[0039] Within the determined set period, the unified management and control device collects the second voice control instructions issued by the user to each intelligent appliance during actual use. These instructions reflect the control requirements and habits of the user for the intelligent appliance and contain various different semantics and formats. From the collected second voice control instructions, the unified management and control device randomly selects some data as the third voice control instruction and the fourth voice control instruction.

[0040] Semantic fuzzification rewriting is performed on the selected third voice control instruction to obtain the fifth voice control instruction. Semantic fuzzification rewriting means making the originally more precise and specific instruction become broader and more ambiguous. For example, rewriting "Adjust the brightness of the living room light to 80%" to "Make the living room light a little brighter". The purpose of this is to simulate the less precise instructions that the user may issue during actual use to test the understanding and processing ability of the intelligent appliance when facing fuzzy instructions.

[0041] Finally, the fifth voice control instruction obtained through semantic fuzzification rewriting and the randomly selected fourth voice control instruction are integrated together to form a voice control information set. This set contains instructions with different semantics and formats and will be used for subsequent testing of the intelligent appliance to further evaluate and understand their semantic understanding ability.

[0042] Through the above steps, the unified management and control device can dynamically adjust the re-evaluation period according to the semantic understanding ability of the intelligent appliance and generate a diversified voice control information set, so as to more comprehensively and accurately evaluate the semantic understanding ability of the intelligent appliance and provide strong support for subsequent realization of more precise unified management and control of cross-brand intelligent appliances.

[0043] Optionally, determining the set period according to each of the second semantic understanding ability levels includes: analyzing the high-low change trend of each of the second semantic understanding ability levels; if the high-low change trend indicates that the semantic understanding ability level of the corresponding intelligent appliance is generally increasing, setting the set period to a first duration; otherwise, setting the set period to a second duration; wherein, the first duration is less than the second duration.

[0044] In this embodiment, the unified management device performs curve fitting on the second semantic understanding ability levels of each recorded intelligent appliance, for example. By analyzing the curve obtained from the fitting, it can be determined whether the semantic understanding ability of the intelligent appliance is improving or remaining stable.

[0045] If the analyzed high-low change trend indicates that the semantic understanding ability level of the corresponding intelligent appliance is generally increasing, it means that the manufacturer is continuously strengthening and updating the semantic understanding ability of the intelligent appliance. In this case, the unified management device sets the set period to the shorter first duration to update its semantic understanding ability level in a timely manner, thereby reducing the subsequent conversion and rewriting of unnecessary voice control information.

[0046] If the analyzed high-low change trend indicates that the semantic understanding ability level of the corresponding intelligent appliance is not generally increasing, it means that the manufacturer has not continuously strengthened and updated the semantic understanding ability of the intelligent appliance. For example, the intelligent appliance is a non-core product or a product about to be phased out by the manufacturer. In this case, the unified management device sets the set period to the longer second duration, which can reduce the waste of computing resources caused by frequent updates.

[0047] Optionally, generating the third voice control information according to the first semantic understanding ability level of the target intelligent appliance includes: if the first semantic understanding ability level of the target intelligent appliance is higher than the level threshold, using the second voice control information as the third voice control information; if the first semantic understanding ability level of the target intelligent appliance is not higher than the level threshold, obtaining the control habit information of the user for the target intelligent appliance, and performing clarification processing on the second voice control information according to the control habit information to obtain the third voice control information.

[0048] In this embodiment, when the first semantic understanding ability level is higher than the above-mentioned level threshold, it indicates that the target intelligent appliance has a strong semantic understanding ability and can understand relatively natural and diverse voice commands input by the user. In this case, the system does not need to perform additional processing on the second voice control information and directly sends it to the target intelligent appliance as the third voice control information. For example, when the user says "Dim the lights in the living room a little bit", for an intelligent lamp with strong semantic understanding ability, the unified management device can directly convey this command to it, and the intelligent lamp can understand and execute the corresponding operation.

[0049] When the first semantic understanding ability level is not higher than the above-mentioned level threshold, it indicates that the target intelligent appliance has relatively limited understanding of voice commands and can only process specific formats or relatively clear and definite commands. At this time, the unified management device further obtains the control habit information of the user for the target intelligent appliance. This control habit information can be collected by recording the user's previous operation commands for the intelligent appliance. For example, the user usually uses precise commands such as "Set the temperature of the bedroom air conditioner to 24 degrees" to control the air conditioner, or is used to adjusting the brightness of the living room lights to 30% at 9 pm.

[0050] According to the obtained control habit information, the second voice control information is clarified, so that the user's relatively vague or broad command can be converted into a precise command that the target intelligent appliance can understand. For example, when the user inputs "Lower the temperature of the air conditioner", the unified management device converts it into "Set the temperature of the air conditioner to 24 degrees" according to the user's usual habit and sends it to the air conditioner as the third voice control information.

[0051] Optionally, forwarding the third voice control information to the target intelligent appliance for execution includes: reviewing the third voice control information based on a preset compliance rule, and if the review passes, forwarding the third voice control information to the target intelligent appliance for execution.

[0052] In this embodiment, in the smart home system, various intelligent appliances are interconnected and work together, and the third voice control information obtained after the above-mentioned clarification process may also be incorrect. To ensure the stable operation of the entire system, the safety of the user, and the normal use of the device, it is necessary to strictly review the control commands sent to the intelligent appliance. For example, a compliance rule including various error and dangerous command situations is preset to review the third voice control information, so as to avoid damage to the intelligent appliance caused by unreasonable or unsafe commands, or potential safety hazards.

[0053] Optionally, the randomly selecting a part of the third voice control instructions and a part of the fourth voice control instructions includes: obtaining a first proportion of the user's clarified voice control instructions for the corresponding smart appliance based on the control habit information analysis, and determining a second proportion of the third voice control instructions and the fourth voice control instructions based on the first proportion.

[0054] In this embodiment, users may have different control habits for different smart appliances. Some users are used to using clear and definite instructions, such as "set the air conditioner temperature in the living room to 25 degrees Celsius", which is a clear voice control instruction; some are used to using more vague instructions, such as "adjust the air conditioner temperature in the living room appropriately", which is a fuzzy voice control instruction. By statistically analyzing the control habit information of the user, the first proportion of the clear voice control instructions of the user for the corresponding smart appliance can also be calculated.

[0055] When the first proportion is higher, the number of randomly selected third voice control instructions can be set to be larger, that is, more third voice control instructions are selected for fuzzy rewriting to achieve a more accurate test of the semantic understanding ability of the corresponding intelligent appliance; conversely, fewer third voice control instructions are selected for fuzzy rewriting to reduce instruction errors caused by improper rewriting, thereby reducing the impact on the accuracy of subsequent evaluation tests. The total number of selected third voice control instructions and fourth voice control instructions can be a fixed value, such as 30. After determining the number of third voice control instructions, the number of remaining fourth voice control instructions can be determined, and then the above-mentioned second proportion is obtained.

[0056] Optionally, the method also includes: the unified management and control device discovers smart appliances by scanning specific broadcast packets, and obtains a pairing code by communicating with the official website network of the corresponding smart appliance or receiving information input by the user, and uses the pairing code to establish a connection with the corresponding smart appliance to connect the corresponding smart appliance to the smart home ecosystem.

[0057] In this embodiment, the smart appliance periodically sends specific broadcast packets during operation. These broadcast packets contain some basic information about the appliance, such as device type, brand, unique identifier, etc. The unified control device continuously scans these broadcast packets within its perceptible network range. When a broadcast packet is scanned, it means that a potentially accessible smart appliance has been found.

[0058] The unified control device needs to use a pairing code to establish a connection with potentially connectable smart appliances. In addition to directly receiving the pairing code input by the user, it can also obtain it through communication with the official website network. The unified control device sends the relevant information (such as the unique identifier) of the discovered smart appliances to the official website server of the appliance brand. After the server verifies that the information is correct, it will return a pairing code to the unified control device.

[0059] After obtaining the pairing code, the unified control device sends the pairing code to the corresponding smart appliance; after receiving the pairing code, the smart appliance verifies it. If the pairing code verification passes, the two parties can establish a secure and stable communication connection. When the unified control device and the smart appliance successfully establish a connection, the smart appliance is officially connected to the smart home ecosystem. After that, the unified control device can manage and control the smart appliance, and the user can also perform various operations on this smart appliance through the unified control device, such as switch control, mode adjustment, etc., so as to achieve the unified control of cross-brand smart appliances in the smart home system.

[0061] An embodiment of the present invention also discloses a computer storage medium, where the computer storage medium stores a computer program, and the computer program is executed by a processor to implement the method as described in the foregoing embodiment.

[0062] Examples of computer-readable media include: read-only memory, random access memory, compact disc read-only, magnetic tape, floppy disk, optical data storage device, and carrier waves (such as data transmission via the Internet through wired or wireless transmission paths). The computer-readable medium can also be distributed among computer systems connected to a network, so that the computer-readable code is stored and executed in a distributed manner. In addition, the functional programs, codes, and code segments for implementing the present invention can be easily interpreted by ordinary programmers in the field related to the present invention within the scope of the present invention.

[0063] An embodiment of the present invention also discloses a computer program product, where the computer program product contains computer code, and when the computer code is executed by a processor of an electronic device, it implements the method as described in the foregoing embodiment.

[0064] Those skilled in the art should understand that the various modules or steps of the present invention described above can be implemented by a general-purpose computing device. They can be concentrated on a single computing device or distributed over a network composed of multiple computing devices. Optionally, they can be implemented by program codes executable by the computing device.

In this way, the present invention is not limited to any specific combination of hardware and software.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
