Referring to fig. 1, in a first embodiment of the present invention, the nutrition intelligent management method is applied to an intelligent management system, where the intelligent management system includes an analysis platform terminal, and an index terminal and a data acquisition terminal respectively connected to the analysis platform terminal through signals; a first analysis model is arranged at the end of the analysis platform; the intelligent nutrition management method comprises the following steps:
step S10, sending daily meal data of a user to the analysis platform end through the data acquisition terminal;
step S20, in a preset period, the analysis platform end stores the received daily meal data of the user but does not process the meal data;
step S30, in the preset period, the analysis platform end acquires the fluctuating health related index data of the user from the index terminal and judges whether the key health index data in the fluctuating health related index data meets the set standard;
step S40, if the key health index data do not meet the set standard, the analysis platform end processes the stored daily diet data of the unprocessed user into analysis data;

and S60, outputting a daily recommended recipe through the first analysis model, and sending the daily recommended recipe to a data acquisition terminal.
According to the technical scheme, daily dietary data of a user are sent to an analysis platform end through a data acquisition terminal, and the analysis platform end stores the daily dietary data but does not process the daily dietary data; meanwhile, the analysis platform end continuously acquires the fluctuating health related index data of the user through the index terminal, and when the key health related index data in the fluctuating health related index data meet the set standard, the analysis platform end processes the stored daily diet data of the user which is not processed into analysis data; processing key health index data which do not meet set standards and the analysis data into input data by an analysis platform end, and inputting the input data into the first analysis model; the first analysis model is used for outputting daily recommended recipes to the user according to the dietary habits and key indexes of the user. The daily recommended recipes output by the first analysis model are sent to the data acquisition terminal, so that the user can conveniently select meals according to the daily recommended recipes, and intelligent nutrition management is achieved according to the meal habits and key index fluctuations of the user.
The daily diet data of the user are sent to the analysis platform end through the data acquisition terminal, the first analysis model is facilitated to analyze the diet preference and the rule of the user, the fluctuation condition of key health index data is facilitated to adjust the daily recommended recipes according to the health conditions of different crowds, and therefore the different users are guided to carry out reasonable diet management.
The index terminal can be connected to the analysis platform end according to needs, for example, the index terminal can be an intelligent wearable device (for example, a sports watch or a wearable device with a blood pressure and blood sugar testing function) for detecting physiological indexes of a user, and can also be a hospital terminal. Meanwhile, the index terminal connected with the analysis platform end through signals can also comprise intelligent wearable equipment and a hospital terminal.
The health-related index data acquired from the index terminal is generally in a fluctuating state and does not remain unchanged. When the index terminal has a function of acquiring various data, the analysis platform end does not pay attention to all data, but only to data that can be improved by meals, or data that can be used to measure the health of meals.
Meanwhile, the data acquisition terminal can also set diet taboos of the user, or intelligently analyze the diet taboos of the user through the health related index data acquired by the analysis platform terminal and the daily diet data of the user.
The data acquisition terminal can be a smart device, such as a mobile phone, a smart wearable device or other smart handheld devices.
In the present invention, the health-related index data includes: at least one of body weight, body fat rate, blood pressure, blood sugar, blood fat, uric acid, and waist circumference, and other indicators for measuring health condition. The health related index data can be determined according to user setting or default setting, and the type of the health related index data acquired by the analysis platform end accords with a set type.
The key health indicator data refers to data that is currently significantly abnormal for the user. Such as blood pressure, blood sugar, blood lipids, uric acid. Wherein, the determination of the key health index data can be performed by referring to the following modes:
the analysis platform end continuously acquires each health related index data from each connected index terminal, judges whether each health related index data is normal or not, and acquires health related index data which is continuously abnormal and can be controlled through meals from the fluctuation process of each health related index data as key health index data.
If the user does not have significantly abnormal data, the key health indicator data may be set as data of interest to the user, such as weight or body fat rate.
The preset period refers to a period of time set by a user or a system, and the length of the preset period is not less than one week. The preset time is beneficial to determining the length of the meal data acquired by the analysis platform end, so that the meal preference and the rule of the user in a period of continuous time can be acquired at the analysis platform end, the error of the accidental event is ignored as much as possible, and the first analysis model is beneficial to making more reasonable meal recommendation.
And in a preset period, the analysis platform end stores the received daily meal data of the user without processing, acquires the fluctuating health related index data of the user from the index terminal and judges whether the key health index data in the fluctuating health related index data meet a set standard. Wherein, the meeting of the setting standard means that the setting change rate is not reached or the setting warning value is not reached. When the key health index data do not meet the set standard, the key health index data are considered to be in the special abnormal condition, and the diet recommendation needs to be given to the user in advance before the end point of the preset period is reached, so that the special abnormal condition can be improved in advance. For example, when the blood sugar of the user fluctuates too much or the blood sugar significantly exceeds the alarm value, the user may be in a special abnormal condition.
If the analysis platform end considers that the key health index data of the user meet the set standard in the preset period, the analysis platform end can process the fluctuation of the key health index data in the preset period and the analysis data into input data and input the input data into the first analysis model when the end point of the preset period is reached.
The key health index data which do not meet the set standard are also used as a part of input data, and scientific guidance on the nutrient intake of different crowds is facilitated through the key health index data. For example, the total intake of fat in hyperlipidemic people is lower than in normal people, and thus a diet with a relatively lower amount of fat in the recommended daily diet is required.
Based on the first embodiment of the present invention, in the second embodiment of the present invention, the analysis platform end is further provided with a second analysis model; the intelligent nutrition management method further comprises the following steps:
step S70, after the daily recommended recipes are generated, daily meal data of the user are sent to the analysis platform end through the data acquisition terminal;
step S80, storing the daily diet data of the user after the daily recommended recipes are generated by the analysis platform end, and processing the daily diet data of the user after the daily recommended recipes are generated into analysis data;
step S90, the analysis platform end inputs the analysis data twice before and after the generation of the daily recommended recipes into the second analysis model;
s100, comparing whether the ratio of evaluation values of the analysis data of the previous time and the next time reaches a preset value or not by a second analysis model;
and step S110, if the preset value is not reached, the analysis platform end sends an alarm prompt to the data acquisition terminal.
In this embodiment, the length of the recipe recommendation period may be equal to the length of the period of the user's daily meal data corresponding to the first analysis data.
And the second analysis model is used for analyzing whether the original nutrition intake defect is corrected by the daily recommended recipe after the daily recommended recipe is generated by the user. I.e. the second analysis model is used to verify whether the user has used the daily recommended recipes.
Specifically, after the recommended recipes are generated every day, when the analysis platform end detects that the time reaches the end of the recipe recommendation period, the analysis platform end processes the daily diet data of the user into analysis data, and whether the ratio of the evaluation values of the two analysis data before and after comparison through the second model reaches a preset value or not is judged.
In step S110, the evaluation value is used to evaluate the degree of deviation of daily meal data of the user from a healthy meal; the ratio of the two evaluation values before and after the generation of the daily recommended recipe is used for judging the degree of adopting the daily recommended recipe by the user. When the ratio of the evaluated values does not reach a set value, the utilization rate of the user to the daily recommended recipes is low, and the effect of correcting the diet cannot be achieved by the daily recommended recipes. Therefore, the analysis platform end sends an alarm to the data acquisition terminal to prompt the user that health risks exist when the recipe diet is not recommended every day. Further, if the preset value is not reached, the analysis platform end can also send an alarm prompt to a related terminal of the data acquisition terminal. The associated terminal may be a hospital terminal or a relative terminal.
Based on the second embodiment of the present invention, in a third embodiment of the present invention, after the step S100, the method further includes:
step S120, if a preset value is reached, the analysis platform end inputs the analysis data generated by the daily recommended recipes into the first analysis model;
step S130, after the daily recommended recipes are generated, the analysis platform end obtains the fluctuating health related index data of the user from the index terminal and judges whether the key health index data in the fluctuating health related index data meet the set standard;
step S140, after the daily recommended recipes are generated, if the key health index data do not meet the set standard, the analysis platform end processes the stored daily meal data of the unprocessed user into analysis data;
step S150, the analysis platform end processes the key health index data which do not accord with the set standard and the analysis data after the daily recommended recipe is generated into input data, and inputs the input data into the first analysis model;
and step S160, outputting the updated daily recommended recipes through the first analysis model, and sending the updated daily recommended recipes to the data acquisition terminal.
In step S120, if the ratio of the evaluation values of the analysis data obtained before and after the comparison by the second analysis model reaches a preset value, which indicates that the degree of the user using the daily recommended recipes is high, the daily dietary data and the fluctuation record of the key health index data can be continuously provided for each round of the user, and the data is input into the first analysis model to continuously obtain the daily recommended recipes at different stages.
The daily recommended recipe has a recipe recommendation period. The recommended diet time period does not exceed the preset time period at the longest, the reason is that the recommended diet every day in the invention is formulated according to the fluctuation of health related index data of the user for a period of time, and the health related index data of the user are different due to the conditioning of medicines or meals at intervals. According to the fluctuation of each period of time, different daily recommended recipes are formulated, and after the fluctuation of the meal data and the health related index data is obtained again in the next period of time, the daily recommended recipes are updated, so that the recommended recipes are dynamically adjusted, and more scientific meal management and control can be realized.
Based on the second to third embodiments of the present invention, in a fourth embodiment of the present invention, the step S10 includes:
step S11, providing a selection diet list at the data acquisition terminal, wherein the selection diet list records diet information ingested every day, and the diet information comprises diet names, food amounts corresponding to the food names, food cooking modes and food meals (morning, noon and evening); after the daily recommended recipes are generated, selecting a diet list as the daily recommended recipes; meal names, i.e., dish names, such as potato meat; the food name is one dish and includes various kinds of foods, for example, the food of the potato-roasted meat includes potato, pork, and the like.
Step S12, obtaining the meals selected by the user from the meal list for selection, and taking all the meals selected by the user on the current day as meal data on the current day;
and S13, the data acquisition terminal sends the acquired daily meal data to the analysis platform terminal.
The fourth embodiment and the fifth embodiment are used for providing different technical solutions for recording daily meal data of a user.
In a fourth embodiment, if the user uses the intelligent management system for the first time, the data acquisition terminal can acquire the health related index data input by the user, so as to provide the selected meal list on a targeted basis every day. And displays the meal list on the data acquisition terminal.
The user may select a meal name from the list of alternative meals to enable rapid entry of daily meal data.
Certainly, the user may also select other meals from the meal list to be selected, and at this time, the meal name selected by the user is entered into the data acquisition terminal, so that the daily meal data of the user can be formed. The recording mode can be as follows: and filling in through an input interface of the data acquisition terminal, or photographing and identifying through a camera of the data acquisition terminal.
And after the user uses the intelligent management system for a period of time, if the daily recommended recipes are generated, selecting the diet list as the daily recommended recipes.
Based on the second to third embodiments of the present invention, in a fifth embodiment of the present invention, the data acquisition terminal is provided with an RFID reader; the step S10 includes:
step S14, each meal of the optional meals on the current day is allocated with an RFID label;
step S15, recording the meal information of each meal in the RFID tag;
step S16, reading an RFID label corresponding to the meal selected by the user through a data acquisition terminal before the meal;
and S17, the data acquisition terminal sends the read RFID tag to the analysis platform end.
The fifth embodiment and the fourth embodiment may be used in combination, or only one of them may be used. The application scenario of the fifth embodiment is suitable for a meal of a lobby, such as a dining hall, or a restaurant. The same meal is marked in the dining room or the restaurant through the RFID tag, and the meal selected by the user can be quickly acquired by the receipt acquisition terminal close to the RFID tag, so that the daily meal data of the user can be quickly input.
In a sixth embodiment of the present invention, based on the fourth or fifth embodiment of the present invention, the analysis platform end processes the daily meal data of the user into analysis data, and refers to the following manner:
step S41, acquiring a nutrition database, wherein the nutrition database stores nutrition data corresponding to food names, and the nutrition data comprises nutrition types and nutrition proportions contained in the food names;
step S42, the analysis platform end processes the diet data of each day of the user into a data unit by inquiring a nutrition database;
and S43, processing each continuous data unit into analysis data by the analysis platform end.
In the present embodiment, the processing of meal data for each day into one data unit is to unify the metrics of meal data for each day.
For example, a meal ingested by a user on a certain day includes: the breakfast comprises 1 egg and 200ml milk, the Chinese meal comprises 200g of rice, 200g of green vegetables and 1 part of fried meat of potato slices, and the supper comprises 200g of rice, 200g of towel gourd and 1 part of fried meat of carrot.
Processing the meal data for the day into data units comprises the steps of:
first, by querying the nutrition database, the daily meal data is converted to total intake for each nutrition type on the day, for example: energy C kilojoule; protein D g; total fat E g; cholesterol E mg; the total amount of carbohydrates is F grams; salt G mg.
Secondly, acquiring set ordering of various nutrition types, and arranging the total daily intake of each nutrition type converted according to the set ordering to form a row matrix, wherein when the daily total intake of a certain nutrition type is 0, 0 is filled in the corresponding position in the row matrix;
and finally, according to the date sequence, arranging the row matrixes obtained by each data unit longitudinally, and carrying out row matrix combination treatment to obtain an analysis data matrix consisting of continuous data units.
In a seventh embodiment of the present invention based on the first to sixth embodiments, the intelligent nutrition management method further includes:
step S170, dividing the time period corresponding to the analysis data into a plurality of nutrition intake time periods according to the fluctuating health-related index data, and respectively setting an intake standard value for the nutrition type required to be taken in each nutrition intake time period;
the step S100 includes:
s101, respectively inquiring an intake standard value of each nutrition type in each data unit in each analysis data by the second analysis model, and calculating to obtain an evaluation value of each data unit;
step S102, determining the evaluation value of the analysis data according to the evaluation values of all data units in each analysis data;
step S103, comparing the evaluation values respectively corresponding to the analysis data of the previous and the next times to determine whether the ratio of the evaluation values of the analysis data of the previous and the next times reaches a preset value.
In step S170, the reason why the period corresponding to the analysis data is divided into a plurality of nutrition intake time periods according to the fluctuating health-related index data is that the recommended intake amounts of the corresponding nutrition types are different in the fluctuation process of the health-related index data. For example, when the blood lipid is normal for a certain period of time in the period corresponding to the analysis data, the intake of the total fat amount per day can be referred to the normal standard intake. When the blood lipid rises to exceed the normal interval in the middle of the period, the intake of the total fat amount per day needs to be reduced. Therefore, according to the fluctuating health-related index data in the analysis period, the period corresponding to the analysis data may be divided into a plurality of nutrient intake periods, and intake standard values are set for the types of nutrients to be taken in each of the nutrient intake periods, respectively. Thereby contributing to obtaining an estimated value of the diet of the day by the deviation between the actual intake amount and the intake standard value for each nutrition type per day; by analyzing the evaluation value of the daily meal of the period corresponding to the data, the overall evaluation value of the meal of the period corresponding to the data can be measured.
