[0027] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0028] This application provides a device control method, apparatus, electronic device, and computer-readable storage medium. Specifically, this application provides a device control apparatus suitable for electronic devices, including terminal devices, which include, but are not limited to, devices with voice interaction capabilities such as mobile phones, tablets, smartwatches, speakers, extended reality devices, air conditioners, refrigerators, or televisions.
[0029] For example, please see Figure 1 , Figure 1 This is a schematic diagram illustrating a scenario where a terminal device, according to an embodiment of this application, executes the device control method. Specifically, the execution process of the terminal device executing the device control method is as follows: Terminal device 101 acquires voice control information, matches the control intent information corresponding to the voice control information from the target cache, and obtains matching result information. The target cache is hierarchically cached according to comprehensive value weight information. If the matching result information indicates that the control intent information is matched, a device control instruction for the control intent information is generated, the device control instruction is executed, and the device control result information is obtained.
[0030] For example, taking an air conditioner as a terminal device, if the terminal device detects the user's control voice, it matches the control intent corresponding to the control voice from the target cache. If a control intent information is matched, a device control command is generated based on the control intent information, and the device control command is executed to obtain device control result information. For example, the intent of the user's voice to adjust the temperature is understood, and then a device command to adjust the temperature is generated and executed to adjust the set temperature of the air conditioner.
[0031] It is understood that after obtaining the voice control information to be analyzed, the terminal device in this application embodiment first matches the corresponding control intent information from the target cache, rather than directly performing the time-consuming actual reasoning task, which helps to speed up the acquisition of control intent information; and obtains the task link to replace the actual reasoning from the target cache, reducing the link delay during voice interaction, alleviating the problem of slow voice response, and improving the user experience.
[0032] Furthermore, the target cache is based on hierarchical cache control, which helps to match control intent information according to the characteristics of hierarchical cache, improves the matching efficiency of control intent information, further reduces link latency, and alleviates the problem of slow response.
[0033] Furthermore, hierarchical caching control based on comprehensive value weight information allows information to be cached hierarchically according to value, improving the efficiency of hitting control intent information, further enhancing the response rate of voice interaction, and improving the user experience.
[0034] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.
[0035] Please see Figure 2 , Figure 2 This is a flowchart illustrating a device control method provided in an embodiment of this application. Although the flowchart shows a logical order, in some cases, the steps shown or described may be executed in a different order than that shown in the flowchart. Specifically, this device control method is applied to a terminal device, and the specific flow of the device control method is as follows: S201. Obtain voice control information.
[0036] Voice control information refers to the instructions given by the user and collected by the device's voice acquisition module for controlling the device. For example, this includes voice commands such as "increase temperature," "increase fan speed," and "reduce noise."
[0037] It is understandable that the voice control information is speech that the device needs to understand. For example, the voice control information needs to be semantically understood before the device can know the user's operation intention, and then generate and execute the device instructions based on the operation intention to respond to the user's voice control.
[0038] S202. Match the control intent information corresponding to the voice control information from the target cache to obtain matching result information, wherein the target cache is hierarchically cached according to the comprehensive value weight information.
[0039] Understandably, the target cache is a cache that stores several intent information. This intent information can be obtained after semantic understanding by a large language model or other semantic understanding model, or it can be obtained by administrators, engineers or users.
[0040] Among them, control intent information is the intent understanding result corresponding to semantic control information, that is, the operation intent corresponding to the voice control information that the device can understand. For example, control intent information includes temperature increase, wind speed increase, or noise reduction.
[0041] In this embodiment, after obtaining voice control information, instead of directly performing a time-consuming semantic understanding task using a large language model or other semantic understanding model, the system first matches the control intent information corresponding to the voice control information from the target cache. It is understood that the information matching process is more time-efficient than the intent reasoning process. Therefore, if control intent information is matched from the target cache, the time required for intent understanding is saved by replacing the time-consuming intent reasoning task, thus improving the efficiency of intent understanding.
[0042] The matching result information refers to the result that indicates whether the control intent information corresponding to the voice control information is matched from the target cache. For example, the matching result information includes whether the control intent information corresponding to the voice control information is matched or not.
[0043] Among them, the comprehensive value weight information is the result of a comprehensive value assessment of information through multiple dimensions, representing the overall value of the information. It can be understood that the higher the comprehensive value weight information, the higher the value of the information; conversely, the lower the comprehensive value weight, the lower the value of the information.
[0044] Among these features, tiered caching control allows for the differentiated storage of different types of information within the cache. In essence, tiered caching based on comprehensive value weighting ensures that information of varying value is stored in the cache according to different hierarchical relationships. This tiered caching design facilitates the rapid matching of corresponding control intent information, thereby improving the efficiency of control intent information matching.
[0045] S203. If the matching result information indicates a match with the control intent information, then a device control command for the control intent information is generated.
[0046] Understandably, if control intent information is matched from the target cache, there is no need to perform the time-consuming intent reasoning task, thus saving intent reasoning time and improving intent acquisition efficiency.
[0047] Among them, device control commands are instructions for controlling the device, which are instructions that the device can understand and execute. By generating device control commands, it is helpful to realize the response to user voice control information based on the device control commands.
[0048] S204. Execute the device control command to obtain device control result information.
[0049] Among them, the equipment control result information refers to the execution result after the equipment executes the equipment control command. The equipment control result information includes at least two categories: successful execution and execution failure. For example, the equipment control result information includes successful temperature increase and failed temperature regulation.
[0050] In summary, after obtaining the voice control information to be analyzed, the terminal device in this application first matches the corresponding control intent information from the target cache, rather than directly performing the time-consuming actual reasoning task, which helps to speed up the acquisition of control intent information; it obtains the task link to replace the actual reasoning from the target cache, reduces the link delay during voice interaction, alleviates the problem of slow voice response, and improves the user experience.
[0051] Furthermore, the target cache is based on hierarchical cache control, which helps to match control intent information according to the characteristics of hierarchical cache, improves the matching efficiency of control intent information, further reduces link latency, and alleviates the problem of slow response.
[0052] Furthermore, hierarchical caching control based on comprehensive value weight information allows information to be cached hierarchically according to value, improving the efficiency of hitting control intent information, further enhancing the response rate of voice interaction, and improving the user experience.
[0053] In this embodiment, the target cache includes a hot cache and a cold cache, and hierarchical caching control of information is achieved through the hot cache and cold cache. Correspondingly, the matching result information includes first matching result information and second matching result information. The step of "matching the control intent information corresponding to the voice control information from the target cache to obtain the matching result information" includes: The control intent information corresponding to the voice control information is matched from the hot cache to obtain the first matching result information; If the first matching result information indicates that the control intent information is not matched, then the control intent information is matched from the cold cache to obtain the second matching result information; If the matching result information indicates a match with the control intent information, then a device control command is generated for the control intent information, including: If the second matching result information indicates a match with the control intent information, then a device control command is generated for the control intent information.
[0054] The first matching result information refers to the result of matching control intent information from the hot cache, which includes at least two types: matching control intent information and not matching control intent information.
[0055] The second matching result information refers to the result of matching control intent information from the cold cache, which includes at least two types: matching control intent information and not matching control intent information.
[0056] It is understood that in the embodiments of this application, if the first matching result information represents a match with control intent information, then there is no need to match the control intent information from the cold cache (such as the Redis cache). That is, the device control instructions can be generated directly using the control intent information matched from the hot cache.
[0057] The hot cache and cold cache are designed according to the frequency of data access. For example, information with high access frequency is cached in the hot cache, and information with low access frequency is cached in the cold cache.
[0058] Understandably, frequently accessed data is typically less abundant, while the cold cache contains a larger amount of data. Therefore, the hot cache matches control intent information more quickly. Thus, matching control intent information first from the hot cache helps improve the efficiency of control intent information matching and reduces the time spent matching from the large amount of data in the cold cache.
[0059] It is understandable that comprehensive value weight information reflects the value of information, and the access frequency of information is one factor reflecting the value of information. Alternatively, when the comprehensive value weight information of information is high, the access frequency of the information is generally also high. Therefore, in this embodiment, intent information (such as control intent information or other intent information corresponding to voice control) can be hierarchically cached between hot and cold caches according to the comprehensive value weight information. For example, control intent information with high comprehensive value weight information is cached using hot caching, while control intent information with low comprehensive value weight information is cached using cold caching.
[0060] In this embodiment of the application, if no control intent information is matched from the target cache, the semantic understanding model is used to perform intent reasoning to obtain the control intent information corresponding to the voice control information. That is, optionally, in some embodiments of the application, after the step "matching the control intent information corresponding to the voice control information from the target cache to obtain matching result information", the method further includes: If the matching result information indicates that the control intention information is not matched, the control intention information corresponding to the voice control information is inferred through the semantic understanding model; The method further includes: The control intent information obtained through reasoning is cached in the hot cache of the target cache, wherein the hot cache is obtained by recalculating the comprehensive value weight information of the cached information in the hot cache of each terminal device based on a set period, and updating it based on the recalculated comprehensive value weight information; The target cache is based on the W-TinyLFU caching architecture.
[0061] Among them, the semantic understanding model is a model for understanding or reasoning about the intent of speech control information. For example, the semantic understanding model includes a large language model.
[0062] Understandably, control intent information derived from reasoning using a large language model is cached in the target cache. It's also understandable that, since this control intent information is currently derived from reasoning using a large language model, it possesses high freshness and can therefore be cached using hot caching.
[0063] Correspondingly, this hot cache can be set up locally on the terminal device. For example, the terminal device can store control intent information with higher comprehensive value weight information locally. It is understandable that, since the voice control data of a single user is relatively small, or the sample size is limited, multiple hot caches corresponding to multiple terminal devices can be used to update the hot caches of each terminal device, thereby improving the accuracy and rationality of the control intent information stored in the hot cache. For example, the server can periodically retrieve the control intent information from the hot caches of multiple terminal devices, then recalculate the comprehensive value weight information of each control intent information, and update each hot cache based on the recalculated comprehensive value weight information.
[0064] It is understood that the embodiments of this application are based on the layered (hot cache and cold cache) design of the W-TinyLFU cache architecture, and combined with the adjustment mechanism of comprehensive value weight information to optimize the allocation of cache resources. Through the layered design, frequently used instructions and high-frequency data are preferentially stored in the high-level cache, reducing access latency, while low-frequency data is stored in the low-level cache, improving the overall cache utilization.
[0065] In this embodiment of the application, the comprehensive value weight information corresponding to the control intent information can be obtained by comprehensively evaluating value information from multiple dimensions. That is, optionally, in some embodiments of this application, if the target cache contains the control intent information, and the target cache includes a hot cache and a cold cache, then before the step "matching the control intent information corresponding to the voice control information from the target cache to obtain matching result information", the method further includes: Calculate at least one dimension of value information corresponding to the control intent information, wherein the dimension of value information includes time dimension value information, space dimension value information, or business dimension value information; Generate comprehensive value weight information based on at least one of the aforementioned dimension value information; The control intent information is stored in the target cache in layers according to the comprehensive value weight information.
[0066] Among them, the time dimension value information focuses on the value of the time dimension, reflecting the popularity trend and freshness of data over time. For example, the earlier the control intent information is from the current time, the lower the time dimension value of the control intent information; the more recent the control intent information is from the current time, the higher the time dimension value of the control intent information.
[0067] Among them, spatial dimension value information reflects the spatial distribution of data, the level of data popularity, and is related to the frequency of data access. For example, depending on whether the control intent information is distributed in frequently accessed areas, areas with high access popularity, areas where issues are relatively scattered and wide-ranging, areas where issues are concentrated but access frequency or access probability is low, or areas where access points are not concentrated, different control dimension values are acquired.
[0068] Among them, the business dimension value information focuses on the importance evaluation of business indicators, which is related to business priority. For example, for air conditioners that mainly focus on music, the music domain has a higher weight; for air conditioners that mainly focus on control tasks, the cache of control instructions has a higher priority; and for air conditioners that mainly focus on emotional interaction, the emotional domain has a higher weight.
[0069] In this embodiment of the application, the value information of the time dimension, the value information of the space dimension, and the value information of the business dimension can be integrated based on the weights of the three dimensions of time, space, and business to obtain a more reasonable comprehensive value weight information.
[0070] It is understood that the embodiments of this application combine multiple dimensions such as time dimension, space dimension and business dimension to conduct comprehensive value weight analysis, improve the accuracy of comprehensive value weight information, and thus improve the rationality of control intent information caching.
[0071] For example, in this embodiment of the application, the time dimension value information can be calculated based on the time interval information from the generation of the control intention information to the current time and the time decay factor, such as the time dimension value information. This can be expressed by the following formula: .
[0072] Where α represents the time decay factor, used to control the impact of data freshness. This time decay factor can be predefined based on experience or actual needs. Where T represents the time interval from now, for example, the time interval from when the control intent information is obtained after inference by a large language model or when it is cached in a hot cache. Here, T reflects the freshness of the data; for example, the larger T is, the larger the time interval from now, and the lower the freshness.
[0073] In this embodiment, spatial dimension value information can be calculated based on the hotspot distribution area corresponding to the control intent information and the access probability corresponding to that hotspot distribution area. The access probability includes the access frequency corresponding to the hotspot distribution area. For example, each distribution area is divided into four regions according to access frequency: popular region, sparse but widespread region, concentrated but rarely accessed region, and isolated region, each region corresponding to an access frequency. By analyzing the region to which the control intent information belongs and using the access frequency corresponding to that region as the access probability, this access probability is based on the spatial dimension value information corresponding to the control intent information.
[0074] In this embodiment, the business dimension value information is calculated based on the business importance information and importance threshold information corresponding to the control intent information. The business importance information refers to the priority or importance of the business corresponding to the control intent information, and the importance threshold information refers to the highest importance among all businesses. Correspondingly, the business dimension value information corresponding to the control intent information can be calculated based on the ratio of the business importance information to the importance threshold information. For example, the business dimension value information of the control intent information... This can be expressed by the following formula: .
[0075] in, Information indicating the importance of the business, Information indicating the importance threshold.
[0076] In this embodiment, a weight threshold can be set to evaluate the comprehensive value weight information, thereby enabling hierarchical control of the caching of control intent information. Optionally, in some embodiments of this application, the step "hierarchically storing the control intent information into the target cache according to the comprehensive value weight information" includes: If the comprehensive value weight information is greater than or equal to the weight threshold, then the control intent information is cached in the hot cache; If the comprehensive value weight information is less than the weight threshold, then the control intent information is cached in the cold cache.
[0077] The weight threshold is used for hierarchical control of hot cache and cold cache. The weight threshold can be set based on experience or actual needs. For example, in this embodiment, the weight threshold is set to 0.8.
[0078] In this embodiment of the application, feedback audio can be generated to indicate the execution status of the device control command. The user is informed of the device's response to the voice control by outputting the feedback audio. For example, the feedback audio may include audio indicating that the air conditioner set temperature has been successfully increased or that the air conditioner fan speed has been successfully increased.
[0079] The feedback audio can be generated based on the device control result information. For example, the feedback audio of the device control result information can be generated by a deep learning-based audio generation model.
[0080] In this embodiment, the feedback audio corresponding to the device control result information can be preferentially matched from the cache to reduce the time consumed when generating the audio through the audio generation model. That is, optionally, in some embodiments of this application, after the step "execute the device control instruction to obtain the device control result information", the method further includes: Match the feedback audio corresponding to the device control result information from the audio cache, and if the feedback audio is matched from the audio cache, output the feedback audio; If the feedback audio is not matched from the audio cache, the feedback audio corresponding to the device control command is generated by the audio generation model and the feedback audio is output.
[0081] The audio cache is used to cache audio, which can be entered by the user or generated by the audio generation model.
[0082] Understandably, outputting feedback audio provides feedback on the user's voice control response. Furthermore, prioritizing matching feedback audio from the audio cache improves matching efficiency, avoiding the time-consuming issue of directly generating audio or using the audio generation model every time. Additionally, when the feedback audio is not in the audio cache, generation through the audio generation model ensures that the terminal device always outputs feedback audio reflecting the device control result, thus enhancing the user experience.
[0083] In summary, after obtaining the voice control information to be analyzed, the embodiments of this application first match the corresponding control intent information from the target cache, rather than directly performing the time-consuming actual reasoning task, which helps to speed up the acquisition of control intent information; and obtain the task link to replace the actual reasoning from the target cache, reducing the link latency during voice interaction, alleviating the problem of slow voice response, and improving the user experience.
[0084] Furthermore, the target cache is based on hierarchical cache control, which helps to match control intent information according to the characteristics of hierarchical cache, improves the matching efficiency of control intent information, further reduces link latency, and alleviates the problem of slow response.
[0085] Furthermore, hierarchical caching control based on comprehensive value weight information allows information to be cached hierarchically according to value, improving the efficiency of hitting control intent information, further enhancing the response rate of voice interaction, and improving the user experience.
[0086] In this application embodiment, the design of hot caching and cold caching, and the priority extraction of data from hot caching, improves the hit or matching efficiency of control intent information, improves the response speed of voice control, and enhances the user experience.
[0087] To facilitate better implementation of the equipment control method of this application, this application also provides an equipment control device based on the above-described equipment control method. The meanings of the terms used are the same as in the above-described equipment control method, and specific implementation details can be found in the descriptions of the method embodiments.
