[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0037] Example 1

[0038] This embodiment proposes a smart cutting board control method for controlling and using the cutting board functions by integrating artificial intelligence technology with traditional cutting boards. Figure 1As shown, the intelligent cutting board control method includes:

[0039] S1, pre-building a term library corresponding to the chopping board function and the input term, wherein the term library includes an offline term library and an online term library corresponding to the chopping board function;

[0040] Traditional cutting boards require manual operation, and their functionality is quite limited, with most being used solely for processing ingredients. In this embodiment, in addition to the traditional cutting board's food processing capabilities, additional functions are added, such as heating and thawing ingredients, sterilizing ingredients, and weighing raw materials. A vocabulary library is constructed with trigger instructions corresponding to these functions. User input on the interactive screen is matched with the vocabulary library to determine the function the cutting board needs to perform. Specifically, for each function, there is a corresponding offline and online vocabulary entry. For example, for the heating function, the offline vocabulary entry is set to "heating." The online vocabulary entry contains various converted expressions related to heating effects, etc.

[0041] S2, setting an interactive screen on one side of the chopping board. When the user turns on the interactive screen, it enters the wake-up word detection mode;

[0042] In this embodiment, the interactive screen is a 7-inch high-definition touch screen for displaying various information and operation menus, and the screen and the surface of the chopping board are integrated into one design, which is beautiful and easy to clean. When the user uses the chopping board, the interactive screen is turned on as a signal to receive user input information and enter the wake-up word detection mode. In addition, a high-definition camera is installed above the chopping board and below the screen to ensure that the ingredients placed on the chopping board can be clearly photographed without affecting the user's normal operation. Users can view ingredient recognition results, recipe details, operation menus, nutritional information and other content through the high-definition touch screen. The high-definition touch screen operates smoothly, responds quickly, supports multi-touch, and is convenient for users to perform operations such as sliding and zooming.

[0043] S3: Receive and analyze the user's voice information. If the voice information contains a preset wake-up word, use the voice information within a preset length range before and after the wake-up word as an input word and match it with the offline word library. If a match is found, issue a corresponding instruction for the offline word to execute the corresponding chopping block function.

[0044] The interactive screen includes an online and offline voice module. This module is an integrated offline and online chip built into the interactive screen. After the interactive screen is turned on, it enters standby mode. When the user needs to use a certain function, they input it through voice. The online and offline voice module analyzes the voice information and first determines whether it contains a preset wake-up word. In this embodiment, the preset wake-up word is "Xiao Lin Xiao Lin". Just like a real-life conversation between people, the offline and online voice module determines the person to be spoken to. By analyzing the wake-up word in the voice information, it determines whether the user wants to use the cutting board.

[0045] However, each user has different expression habits. Users may be accustomed to putting the name of the conversation partner at the beginning of the demand expression, or at the end of the demand expression, or during the demand expression process. If the user's needs are judged based on the content after the wake-up word, key information may be missed. For those who are accustomed to putting the name at the end of the demand expression, it may even be considered that the function does not need to be executed, which easily leads to the user needing to repeat the demand. To avoid the above situation, in this embodiment, when the voice module receives the preset wake-up word, it will wake up and further analyze the voice information before and after the wake-up word. For example, the wake-up word as a whole can be analyzed. The partial voice information of the length of fifteen words before the wake-up word and the length of fifteen words after the wake-up word can be analyzed to ensure that users with different expression habits do not need to repeat their needs many times.

[0046] like Figure 2 As shown, the segmented portion of the voice message is used as the input term and matched against the offline term library. For example, if the user's voice message is "Xiaolin Xiaolin, help me heat these meat ingredients," the input term "help me heat these meat ingredients" is matched to "heat" in the offline term library. It can be determined that the user requires the cutting board to perform the function of heating. Then, a control instruction for heating the cutting board is issued, controlling the high-performance heating element installed in the cutting board to evenly heat the cutting board, and the heating progress of the cutting board is displayed on the interactive screen.

[0047] S4, if the offline term is not matched, performing format conversion processing on the input term through the first online voice service, and performing purpose analysis on the processed input term;

[0048] S5, matching the result of the purpose analysis in the online entry library, if the online entry is matched, issuing the IOT instruction corresponding to the online entry to execute the corresponding chopping board function.

[0049] For example, if a user's voice message is "Xiaolin Xiaolin, I want to heat the ingredients higher," then the input term "I want to heat the ingredients higher" cannot be matched to a fixed offline term in the offline term library. The first online voice service uses ASR (Automatic Speech Recognition) to convert the voice-formatted input term into corresponding text data. This text data is then imported into a large language model for purpose analysis. For example, if the purpose analysis result is "the user wants to heat the ingredients," this result is matched with the online term library. If a match is found for an online term related to heating ingredients, it is determined to be a device control command. The built-in IoT platform issues an IoT command, controlling the high-performance heating element installed in the cutting board to evenly heat the board, and displays the heating progress on the interactive screen.

[0050] Preferably, it also includes: matching the result of the purpose analysis in the online entry library, and if the online entry is not matched, calling the second online voice service to process and analyze the result of the purpose analysis to obtain an open reply text; converting the open reply text into audio data, and issuing a corresponding IOT instruction for playback.

[0051] The purpose analysis results are matched against the online term library. If no online terms are matched, the input term is determined not to be a device control command but an open-ended question and answer. The online voice service is then called to process the TTS analysis results for the purpose analysis. For example, if the user's voice message is "Xiaolin Xiaolin, how's the weather today?", the input term is "how's the weather today?" The first online voice service performs ASR processing and then performs purpose analysis on the processed input term using the large language model. The analysis result is "the user wishes to know the weather today." The analysis result is matched against the online term library. If no results related to weather content are matched, the analysis result "the user wishes to know the weather today" is used as input to the large language model for open-ended content analysis. For open-ended user questions and answers, the analysis result is a piece of text data, not a specific device control command. That is, after obtaining the analysis result for "the user wishes to know the weather today," it is input into the second online voice service for TTS (Text to Speech) processing and converted into audio data. The built-in IoT platform then issues IoT commands to play a voice response to the user.

[0052] Preferably, the input word is format-converted by the first online voice service, and the purpose analysis of the processed input word is performed, including:

[0053] The input word is converted from voice data to text data through a first online voice service process; and the text data is input into a large language model for purpose analysis.

[0054] If no fixed offline entry corresponding to the input entry can be found in the offline entry library, the first online voice service uses ASR (Automatic Speech Recognition) to convert the voice-formatted input entry into corresponding text data. This text data is then imported into the large language model for purpose analysis. After receiving the text data, the large language model performs a series of processing steps, including text cleaning, intent recognition, entry expansion, and entity recognition, ultimately generating a corresponding text response, i.e., the result of the purpose analysis.

[0055] Preferably, receiving and analyzing the user's voice information further includes:

[0056] If the voice information does not contain the preset wake-up word, the voice information is filtered and the state of continuously receiving the voice information is maintained.

[0057] In real-world kitchen scenarios, the kitchen may be used by one or more people. Some users prefer to use other peripherals to listen to external voice messages while preparing food. For example, they might listen to a blog or music while preparing food. The offline voice module continuously receives these voice messages. Without a wake-up word, every user's voice message will be analyzed, requiring the user to manually stop the process, which is inconvenient. Therefore, a wake-up word is set. If a voice message containing the wake-up word is analyzed, the user is determined to be using the offline voice module, requiring the use of the cutting board function or answering the user's questions and providing open-ended responses. If the analyzed voice message does not contain the wake-up word, the user is deemed not to be using the offline voice module. The module then filters the received voice message and continuously monitors subsequent voice messages for wake-up word detection.

[0058] Preferably, after executing the corresponding instruction issued, the wake-up word detection mode is entered again and the operation status of the chopping board function being implemented is displayed through the interactive screen.

[0059] After the corresponding command is issued, the corresponding device will perform the corresponding operation and function, such as turning the device on and off, enabling the food identification function, playing voice or music, etc. After the device executes the command, it is considered that the received voice message has been processed and enters the wake-up word detection mode again, waiting for the next voice message containing the wake-up word and executing it. While the device executes the command, the interactive screen displays the function operation status to the user, so that the user can clearly understand it.

[0060] After the device completes the execution, it synchronizes data with the IOT platform, including the user's voice information, matched entries, device status and other information.

[0061] Preferably, if the voice information contains a preset wake-up word, before matching the voice information within a preset length range before and after the wake-up word in the vocabulary library, it also includes: returning a wake-up word confirmation tone reply to the user.

[0062] When the voice message contains a wake-up word, the offline voice module is triggered to wake up, and a confirmation reply tone is broadcast through the speaker, such as "Master, I'm here", and then the user's voice message is processed.

[0063] Preferably, the method further includes: sending the voice information via a remote interaction method.

[0064] In this embodiment, the remote interaction method is to develop a dedicated mini-program, use a mobile device to connect to the smart cutting board in the mini-program via Wi-Fi or Bluetooth, send voice messages, and realize remote control and data interaction.

[0065] Preferably, before executing the corresponding chopping board function, the method further includes: adjusting the parameters of the chopping board function through the remote interaction method or the interactive screen.

[0066] Users can use the mini-program on their mobile device to set parameters for the cutting board's functions, such as adjusting the heating temperature, initiating the disinfection process, and viewing and modifying meal plans, making it easy for users to manage the smart cutting board in different scenarios. Users can also check the working status of the smart cutting board, such as heating progress, disinfection completion, memo information query, and ingredient management, anytime and anywhere on their mobile device.

[0067] Through the above control methods, combined with convenient voice interaction, screen display and remote interaction functions, the traditional chopping board function is combined with modern intelligent technology to provide intelligent services, fully meet the diverse needs of users in kitchen scenarios, and improve the quality and efficiency of kitchen life.

[0068] Example 2

[0069] Based on the same principle as the above method, an intelligent cutting board control device 100 is also proposed. Figure 3 , shown, including:

[0070] The vocabulary building module 110 is used to pre-build a vocabulary library corresponding to the chopping board function and the input vocabulary, wherein the vocabulary library includes an offline vocabulary library and an online vocabulary library corresponding to the chopping board function;

[0071] A wake-up word detection module 120 is configured to provide an interactive screen on one side of the cutting board, and enter a wake-up word detection mode when the user turns on the interactive screen;

[0072] An input information analysis module 130 is configured to receive and analyze a user's voice information. If the voice information contains a preset wake-up word, the voice information within a preset length range before and after the wake-up word is used as an input term.

[0073] An offline term library matching module 140 is used to perform matching in the offline term library and, if an offline term is matched, issue a corresponding instruction of the offline term to execute a corresponding chopping block function;

[0074] a purpose analysis module 150 for performing format conversion processing on the input term through the first online voice service and performing purpose analysis on the processed input term if no offline term is matched;

[0075] The online term library matching module 160 is used to match the result of the purpose analysis in the online term library. If an online term is matched, the IOT instruction corresponding to the online term is issued to execute the corresponding chopping board function.
