[0001] The present application relates to the technical field of intelligent dining table, in particular to a health data control method and system for intelligent dining table. BACKGROUND

[0002] Dining table generally refers to a table for dining, and there are various types of dining tables, including intelligent electric dining table. The intelligent electric dining table is usually a kind of dining furniture with an electric turntable installed on the surface of a large round table. The electric turntable is driven by a motor to rotate automatically at a low speed, which facilitates the diners to take food.

[0003] With the development of health, it is usually necessary to weigh the amount of food to control diet. The existing intelligent electric dining table is usually equipped with a weighing function to weigh the weight of food. The user controls the food according to the weight, but the weight data obtained by the intelligent electric dining table usually cannot be linked with food recognition and user identity confirmation, resulting in the inability to associate the user's health data and control. Therefore, it is necessary to use the health data control method to weigh the food while linking with food recognition and user identity confirmation, and associating the user's health data in real time. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a health data control method and system for intelligent dining table, which solves the problem that the food recognition and user identity confirmation cannot be linked, resulting in the inability to associate the user's health data and control.

[0005] To achieve the above purpose, the present application realizes the following technical scheme: a health data control method for intelligent dining table, comprising the following specific steps: Step 1: data pre-collection and initialization, constructing a dynamic health profile database containing personnel nutritional tolerance and a database associated with food information, and completing the preliminary binding of user ID and food ID through the main body of intelligent dining table; Step 2: real-time control during meal, the weighing sensor of the weighing unit collects the weight, the food reading core board reads the RFID tag at the bottom of the draining tray to obtain the food ID, the chopstick holder reads the user ID confirmed by the core board, and automatically records the data of user ID, food ID and clamping weight, and associates the data with personnel health data, calculates real-time nutritional intake, dynamically adjusts the intake suggestion and displays it through the interactive interface of the main body of intelligent dining table; Step 3: feedback after meal, summarize the data of the day to generate a nutrition report, synchronize to the user terminal and store it encrypted; Step 4: long-term optimization, based on historical weighing data, RFID identification records and health goals, optimize menu recommendation and system parameters to form a closed-loop management.

[0006] Preferably, the nutritional tolerance of the personnel in step one includes protein, fat, and cholesterol. The construction of the dynamic health record database in step one specifically includes generating a table of diners, which contains user ID, name, identity type, and various nutritional tolerance data. The various nutritional tolerance data are the daily intake of protein, fat, and cholesterol. A unique QR code is generated based on each row of user data. The QR code contains user ID and identity verification information.

S4: The chopstick holder reads the user ID associated with the chopstick holder, binds the clamping weight to the user ID, and records it.

[0009] Preferably, in step S4, the user ID associated with the chopstick holder specifically includes a binding QR code inside the chopstick holder and an RFID tag at the bottom. The user scans the QR code to bind the ID. When the chopstick holder is placed in the preset area on top of the main body of the smart dining table, the chopstick holder reading core board reads the RFID tag at the bottom of the chopstick holder and reads the bound user ID.

[0010] Preferably, the dynamic adjustment of intake recommendations in step two specifically includes uploading the clamped weight data from the weighing sensor and uploading the dish ID from the dish reading core board, then calling the unit nutrient composition of the dish in the dish database, calculating the total amount of nutrients currently ingested, and simultaneously retrieving the daily tolerance threshold from the personnel's health record to compare the current intake with the tolerance threshold. When the percentage is ≤60%, a prompt indicating that it can be consumed normally will be generated; When 60% < percentage ≤ 80%, a suggestion to consume an appropriate amount is generated; When 80% < percentage ≤ 95%, a warning is generated indicating that the intake is approaching the upper limit of tolerance and should be reduced. When the percentage is > 95%, a warning is generated indicating that the tolerance limit has been reached and intake should be stopped. All prompts and warnings are displayed through the human-computer interaction interface of the main body of the smart dining table (1) and accompanied by voice broadcast.

[0011] Preferably, the nutrition report generated in step three specifically includes: The daily intake table displays the actual total intake of protein, fat, and cholesterol for each user, categorized by user identity type. Nutritional comparative analysis calculates the difference between the daily intake and the corresponding nutrient tolerance level, and marks the status as adequate, insufficient, or excessive. The contribution percentage of each dish is calculated as the percentage of total daily intake of protein, fat, and cholesterol.

[0012] Preferably, the basis for the optimized menu recommendation in step four includes the average weight and frequency of different dishes picked up by users in historical data, the rate of users' nutritional intake compliance, and the compatibility of dish cooking data with users' health status.

[0013] Preferably, the long-term optimization in step four includes summarizing the historical clamp weight data accumulated by the weighing unit, analyzing users' preferences for different dishes, combining the RFID tag identification records of the dish reading core plate, statistically analyzing the types of dishes frequently selected by users, associating changes in nutritional tolerance in health records, and adjusting the dish combinations and portion suggestions of the recommended menu.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This application provides a health data control method and system for smart dining tables, solving the problem that the inability to link with food identification and user identity verification leads to the inability to associate user health data and control. When a plate is placed, the weighing pan triggers the weighing sensor to collect the initial weight, and the food reading core plate simultaneously reads the RFID tag at the bottom of the draining tray to automatically obtain the food ID. After the user picks up the food, a second weighing is performed to calculate the picked weight, and the chopsticks holder reads the core plate to confirm the user ID. This facilitates the automatic binding of user ID, food ID, and picked weight, enabling real-time association with personal health data and dynamic adjustment of intake recommendations.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This invention discloses a health data control method and system for smart dining tables.

[0023] According to the appendix Figures 1-7 As shown, the specific steps include the following: Step 1: Data pre-collection and initialization, constructing a dynamic health record database containing personnel nutritional tolerance and a database of associated dish information, and completing the initial binding of user ID and dish ID through the smart dining table main body 1; Step Two: Real-time monitoring during the meal. The weighing sensor 54 of the weighing unit 5 collects the weight. The food reading core plate 53 reads the RFID tag at the bottom of the draining tray 511 to obtain the food ID. The chopstick rest reads the user ID confirmed by the core plate 510 and automatically records the user ID, food ID, and the weight of the food being picked up. This data is then linked to the user's health data to calculate real-time nutritional intake, dynamically adjust intake recommendations, and display the results through the interactive interface of the smart dining table main body 1. Tag information entry needs to be integrated with the smart dining table menu management process, employing a two-step operation of pre-entry and binding: First, a menu entry is created in the backend management system, entering core data such as menu ID, name, nutritional components per unit (protein, fat, and cholesterol content per 100g), and cooking parameters to generate a structured menu information package. Then, using an RFID writing device (supporting the 13.56MHz high-frequency band, suitable for dining table scenarios), the unique menu ID and basic information (such as the menu name abbreviation) from the menu entry are encrypted and written to the RFID tag at the bottom of the drain tray 511, completing the one-to-one binding of menu data and tags. Furthermore, secondary modifications are supported after writing (e.g., rewriting the tag information when menu parameters are updated), ensuring real-time synchronization between tag information and the backend database. Tag recognition is achieved through the food reading core board 53 of the smart dining table weighing unit. This food reading core board 53 integrates a ring-shaped radio frequency card reader antenna (its coverage area completely overlaps with the area where the draining tray 511 is placed) and is triggered in conjunction with the weighing unit 5: when the draining tray 511 with the RFID tag is placed on the weighing pan 51 along with the dish tray 4, the weight of the weighing pan 51 triggers the weighing sensor 54 to start. At the same time, the food reading core board 53 is automatically powered on and emits a high-frequency radio frequency signal. After receiving the signal, the RFID tag is activated and feeds back the food ID and other information stored inside to the food reading core board 53 through the radio frequency signal. The food reading core board 53 decodes and decrypts the feedback signal and uploads the food ID to the backend server. The server retrieves the corresponding nutritional components, cooking parameters and other data according to the food ID to complete the tag recognition and data association. The entire recognition process takes ≤0.5 seconds and supports the simultaneous recognition of multiple tags (suitable for multi-person dining scenarios). Step 3: Post-meal feedback, summarizing the day's data to generate a nutrition report, synchronizing it to the user's terminal and storing it in encrypted form; Step 4: Long-term optimization. Based on historical weighing data, RFID identification records, and health goals, optimize menu recommendations and system parameters to form a closed-loop management system.

[0024] The nutritional tolerance data for individuals in Step 1 includes protein, fat, and cholesterol. The construction of the dynamic health record database in Step 1 specifically includes generating a table of diners, containing user ID, name, identity type, and nutritional tolerance data for each nutrient level (the daily allowable intake of protein, fat, and cholesterol). A unique QR code is generated for each row of user data. The QR code generation rule uses the QR code encoding standard, combining the user ID, identity type identifier, and verification code in the specified format. After conversion using the UTF-8 character set, a 200×200 pixel QR code image is generated and placed within the table. The QR code contains the user ID and identity verification information. The database associated with the dish information in Step 1 specifically includes entering basic dish information, including name and unit nutritional components, and associating it with the RFID tag code on the bottom of the draining tray 511.

[0025] In step two, the weighing sensor 54 collects weights, specifically including real-time collection of the total weight of the weighing pan 51, the vegetable plate 4, the draining pan 511, and the vegetables. The RFID tag in step two is used to pre-store the unique identification information of the vegetables. The calculation of real-time nutrient intake in step two specifically includes obtaining the unit nutrient content of the corresponding vegetables in the vegetable database. The unit nutrient content is the protein, fat, and cholesterol content per 100g. Combined with the gripping weight collected by the weighing unit 5, the actual number of grams of protein, fat, and cholesterol ingested at the time is calculated. The calculation formula can be gripping weight (g) ÷ 100 × unit nutrient content, generating real-time nutrient intake data.

[0026] The specific steps of the dish identification process in step two include: S1: When the vegetable tray 4 is placed on the weighing pan 51, the water-blocking plate 55 forms a closed weighing area, and the weighing sensor 54 collects the initial total weight. S2: The food reading core board 53 synchronously reads the RFID tag at the bottom of the draining tray 511, obtains the food ID, and matches it with the food information in the database; S3: After the user uses chopsticks 3 to pick up the food, the weighing sensor 54 collects the remaining weight and calculates the weight picked up by combining the initial total weight and the remaining weight. S4: The chopstick holder reading core board 510 reads the user ID associated with the chopstick holder 2. The chopstick holder reading core board 510 integrates a ring radio frequency card reader antenna, which binds and records the clamping weight with the user ID.

[0027] In step S4, the user ID associated with the chopstick holder 2 specifically includes a binding QR code inside the chopstick holder 2 and an RFID tag at the bottom. The user scans the QR code to bind the ID. When the chopstick holder 2 is placed in the preset area on top of the main body 1 of the smart dining table, the chopstick holder reading core board 510 reads the RFID tag at the bottom of the chopstick holder 2 and reads the bound user ID. At the same time, it performs double verification with the user ID read from the RFID tag on the plate, which helps to ensure that the weight picked up is accurately attributed to the corresponding user and avoids data confusion.

[0028] The dynamic adjustment of intake recommendations in step two specifically includes the weighing sensor 54 uploading the clamped weight data and the dish reading core board 53 uploading the dish ID, then calling the unit nutrient composition of the dish in the dish database, calculating the total amount of nutrients currently ingested, and at the same time retrieving the daily tolerance threshold in the personnel's health record to compare the current intake with the tolerance threshold. When the percentage is ≤60%, a prompt indicating that it can be consumed normally will be generated; When 60% < percentage ≤ 80%, a suggestion to consume an appropriate amount is generated; When 80% < percentage ≤ 95%, a warning is generated indicating that the intake is approaching the upper limit of tolerance and should be reduced. When the percentage is > 95%, a warning is generated indicating that the tolerance limit has been reached and intake should be stopped. All prompts and warnings are displayed through the human-computer interaction interface of the smart dining table 1 and accompanied by voice broadcast.

[0029] The nutrition report generated in step three specifically includes: The daily intake table displays the actual total intake of protein, fat, and cholesterol for each user, categorized by user identity type. Nutritional comparative analysis calculates the difference between the daily intake and the corresponding nutrient tolerance level, and marks the status as adequate, insufficient, or excessive. The contribution percentage of each dish is calculated as the percentage of total daily intake of protein, fat, and cholesterol.

[0030] The optimized menu recommendations in step four are based on historical data, including the average weight and frequency of different dishes picked up by users, the rate of users meeting nutritional intake standards, and the compatibility of dish cooking data with users' health status.

[0031] The long-term optimization in step four includes summarizing the historical gripping weight data accumulated by the weighing unit 5, analyzing users' preferences for different dishes, combining the RFID tag identification records of the dish reading core plate 53, statistically analyzing the types of dishes frequently selected by users, associating changes in nutritional tolerance in health records, and adjusting the dish combinations and portion suggestions of the recommended menu.
