1 is a block diagram showing the configuration of the present invention.

The dietary management system of the present invention includes a menu information database 110, a user information database 120, a location information checking unit 130, a menu extracting unit 140, a calorie output unit 150, and a nutrient output unit 160. It includes.

The menu information database 110 is for each restaurant such as the amount of stock and corrosion of the menu, the amount of stock and corrosion of the menu, the amount of nutrients, the amount of nutrients and the total amount of stock and corrosion of the menu, and the amount of nutrients. Information about calories and nutrients in each menu is stored.

For example, for one serving of Kimchi stew at Restaurant A in Sinchon, information about kimchi stew 00g, rice 00g, kimchi 00g, calamari 00g, and egg powder 00g is provided, information about calories and nutrients in each food, and The total calories for kimchi stew and the amount of total nutrients are stored.

Registered nutrients can be stored by researching all the nutrients, and storing only the salt content, mineral / vitamin content, dietary fiber content, and fat (saturated fat) content, which are generally considered important in diet, etc. It may be.

This information is preferably examined by examining the food of a restaurant that is subscribed in advance, so that the surveyed contents are stored.

In addition, it is preferable that the menu information database 110 also store information on the amount of calories and nutrients of the food in which the amount of calories and nutrients is determined, such as processed foods.

For information on the amount of calories and nutrients of each restaurant's menu stored in the menu information database 110, a person of the operator of the system visits each restaurant and examines the amount of food and ingredients of each menu. Based on this, it is preferable to calculate the amount of calories and nutrients of each menu and to configure the menu information database 110 using the calculated values.

If the operator of the system is not able to investigate directly, the amount of raw materials used for each menu from each restaurant (e.g., cabbage 00g, red pepper powder 00g, salt 00g, meat 00g, etc. for kimchi stew) can be used online or offline. It is preferable to use the calculated value by calculating the amount of calories and nutrients of the menu of each restaurant based on the received through the method. In this case, the calorie and nutrient amount per unit mass for each raw material is registered in the menu information database 110. When only the amount of the raw material is input, the calorific output unit 150 and the nutrient output unit 160 are automatically described below. The amount of calories and nutrients is preferably calculated to be registered in the menu information database (110).

In addition to the basic information of each registered user, the user information database 120 includes information on the recommended intake of the nutrients, such as the age of the user, when the user is limited intake of specific nutrients such as salt, or when the intake of specific nutrients is recommended. Information that can be used by the user as a reference to food intake is stored. In addition, in the case of providing the user with the amount of nutrients in the menu selected by the user, when the user specifies to provide only information on a specific nutrient, information specially designated by the user is stored, such as the information thereof.

Information that can be a reference with respect to food intake is preferably received and stored from the user only when the user requests calculation of calorie or nutrient intake using the standard.

In addition, the user information database 120 may store the contents when the user inputs the type and amount of food ingested, and the amount of calories and / or nutrients calculated therefrom may be stored.

The location information checking unit 130 checks the location of the user. When the dietary management system of the present invention is installed and operated in a server capable of wireless internet, the user's location is identified using a signal transmitted from the user's wireless terminal.

The method of confirming the location may include receiving location information of a user calculated using a GPS signal from a user's wireless terminal, or receiving a result of tracking a location of the user's wireless terminal based on a base station through a communication company. Verification methods can be used, and there is no limitation.

Even when the dietary management system of the present invention is installed in the wireless terminal, it is also possible to use the existing positioning method.

The menu extractor 140 extracts a menu of a restaurant suitable for the user based on the amount of calories or nutrients recommended for the user.

At this time, the menu extracting unit 140 is selected from the menu of the restaurant located in the area where the user is located by using the location information of the user identified by the location information checking unit 130 and the location of each restaurant stored in the menu information database 110. It is desirable to extract a menu recommended for the user.

If the user designates a specific location, it is preferable to extract a menu recommended for the user from the list of restaurants within a predetermined distance and the menu list of the restaurant from the specific location designated by the user.

In addition, when the user designates a restaurant, it is preferable to extract a menu recommended for the user from the menu held by the restaurant.

In addition, the user inputs the type and amount of food ingested per day through the user's wireless terminal or wired Internet, calculates the amount of calories and / or nutrients ingested by the user, and extracts the user's menu based on this. It is preferable.

For example, if the calculation is based on the type and amount of food eaten for breakfast and lunch entered by a user whose daily salt intake is limited to 10g or less, and the result is that 7g is consumed, It is desirable to extract the list of menus whose total salt content of corrosion is 3 g or less and provide them to the user.

In this case, the menu list may be simply extracted based on the total amount of the restaurant menu, but the menu list may be extracted based on only a partial amount.

For example, rice may be extracted based on the amount of calories or nutrients calculated based on the intake of half of the other side dish, even if it is based on one air. In this case, the reference amount of each food included in the menu may be set in advance by the system designer, or may be calculated based on the input from the user when the user requests the extraction of the menu.

Since the method of calculating the amount of calories or nutrients ingested by the user by inputting the type and amount of food is generally known, a detailed description thereof will be omitted.

When the user inputs a menu of a restaurant, the calorie output unit 150 extracts or calories from the menu information database 110 the calories obtained from the intake of each food of the restaurant menu or outputs the same based on this.

In this case, calories may be output based on the total amount of food constituting one menu or calories may be output based on a predetermined amount of each food constituting one menu.

For example, in the case of a menu called kimchi stew, calories can be calculated based on the amount of each food, such as a bowl of rice provided by the restaurant, kimchi stew 3/4, and kimchi 1/2.

The amount of each food may be set by the system designer in advance by using statistics on the amount of each side dish that people generally eat, or may be inputted by the user in advance or the amount eaten.

If the menu of the restaurant selected by the user is not a menu of the restaurant registered in the menu information database 110, it is preferable to calculate and output calories using an average value corresponding to the menu.

For example, if a user ordered kimchi stew at restaurant A, and the restaurant A is not registered, the information on the kimchi stew of all restaurants that have kimchi stew as a menu among the registered restaurants is averaged. As a guide, users should be informed about their calories.

When the user inputs the menu of the restaurant, the nutrient output unit 160 extracts from the menu information database 110 or calculates the amount of nutrients obtained from the intake of each food of the restaurant menu and outputs the calculated value to the user. .

In this case, as in the calorie output unit 150, the amount of nutrients may be output based on the total amount of food constituting one menu, or the amount of nutrients based on a predetermined amount of each food constituting one menu. In the case of outputting the amount of nutrients based on a predetermined amount, the amount may be set by the system designer in advance, or may be inputted in advance by the user or the amount eaten. .

In addition, when outputting the amount of nutrients, all of the various nutrients may be output or may be output only for the specific nutrients specified by the user.

The dietary management system of the present invention may be implemented in the form of providing a service to each user who has a wireless terminal through a server, or may be installed in a user's wireless terminal. When the dietary management system of the present invention is installed in a wireless terminal, the information on the user will be stored and used only for information on one user using the wireless terminal, and in the case of being installed in the server, the information on all registered users. Will be stored and used.

In addition, although not described in detail in the above description, when the dietary management system of the present invention is installed on the server, each component that transmits and receives information to the user has a function of transmitting and receiving with the user's wireless terminal or each It can be seen that there is.

Since it is difficult for the general public to estimate the relationship between the volume and mass of each food, even if the amount or calories of nutrients per unit mass of a particular food is known, the amount of calories or nutrients actually consumed through the foods eaten It's hard to know.

In addition, since the amount of calories and nutrients per unit mass will vary according to the ratio of various raw materials used to make the food, even for the same food, the name of the food and the amount of calories and nutrients per unit mass of the food are uniform. Just telling the amount is not enough to know the exact amount of calories and nutrients that can be consumed by the restaurant's food.

The dietary management system of the present invention does not provide the amount of calories or nutrients to the user on a per unit mass basis, but on the basis of the amount provided in each restaurant, and also provides the respective menus in units. Easily know the amount of calories or nutrients through their food, and more efficient diet management is possible.

Using the dietary management system of the present invention, it is possible to provide a dietary management service of various forms. Representative examples thereof will be described below.

2 is a flow diagram illustrating a method of one preferred embodiment of the present invention.

First of all, the system operator is responsible for each restaurant such as the menu, the amount of stock and corrosion of the menu, the amount of stock and corrosion of each menu, the amount of nutrients, the amount of nutrients and the total amount of stock and corrosion of the menu, and the amount of nutrients. Information about calories and nutrients of each menu is stored in the menu information database 110 of the server or stored in the menu information database 110 of the dietary management system installed in the user's wireless terminal (201).

Since the process of registering information on the amount of calories and nutrients for each menu of each restaurant in the menu information database 110 has already been described with reference to FIG. 1, further description thereof will be omitted.

In order to inform the user of the amount of calories and / or nutrients, the user first selects a specific menu of a specific restaurant (202).

There may be various ways of receiving a specific menu from the user. The restaurant and menu names may be input directly from the user in the form of text, and a list of restaurants within a predetermined distance and a menu list of the restaurants may be output from the user's current location or a specific location designated by the user, and the user may be selected from among them. Alternatively, the user can go directly to a restaurant and use a wireless terminal to read information stored in a radio frequency identification tag, a barcode, and a hot code attached to the restaurant's menu. You can also let them know.

When the user selects a menu, according to the user's selection, the calorie output unit 150 outputs the calories when the menu is ingested so that the user can see it, and the nutrient output unit 160 ingests the menu. The amount of nutrients in the output to be visible to the user (203).

Here, the amount of calories and / or nutrients may be output based on the total amount of foods constituting one menu, and the amount of calories and / or nutrients is determined based on a predetermined amount of each food constituting one menu. It can also be output as described earlier.

In addition, if the menu of the restaurant selected by the user is not the menu of the restaurant registered in the menu information database 110, the calorie or nutrient amount may be output using the average value corresponding to the menu. As shown.

In addition, when outputting the amount of nutrients may be output to all of the various nutrients, as described above, it is also possible to output only a specific nutrient specified by the user.

3 is a flowchart illustrating a method of another embodiment of the present invention.

The system operator stores information on the amount of calories and nutrients in each menu for each restaurant in the menu information database 110 of the server, or in the menu information database 110 of the dietary management system installed in the user's wireless terminal. The process is the same as in Figure 2 (301).

If the user designates a specific location (302), if the user does not specify a specific location location information check unit 130 checks the location of the user using a known method (303).

When the location of the user is confirmed, the menu information database 110 informs the user of the name of the restaurant located within a predetermined distance from the place where the user is located and the menu name of the restaurant (304).

On the other hand, if the user designates a specific location (302), the menu information database 110 informs the user of the restaurant name and the menu name of the restaurant located within a predetermined distance from the place designated by the user (305).

When the user selects one of the menus provided, the calorie output unit 150 and / or the nutrient output unit 160 outputs the amount of calories and / or nutrients of the menu selected by the user to inform the user (306).

The process of outputting calories and / or nutrients is the same as described in FIGS. 1 and 2 and will not be described herein any further.

Meanwhile, the method of the present invention may be linked to a known map information providing method so that when a user selects a restaurant or a restaurant menu, the user may easily find a restaurant by providing a map around the corresponding restaurant to the user ( Not shown).

4 is a flowchart illustrating a method of another embodiment of the present invention.

The system operator stores information on the amount of calories and nutrients in each menu for each restaurant in the menu information database 110 of the server, or in the menu information database 110 of the dietary management system installed in the user's wireless terminal. The process is the same as in Figures 2 and 3 (401).

The user enters information that can be a reference to the user's food intake, such as the amount of nutrients, his daily intake, meals, and nutrients that are specifically restricted or required by the user when registering in the system. 120, at 402. For users who do not have specially required criteria, the criteria set by the system operator apply.

The user inputs the type and amount of food he ingested during the day (403).

The calorie output unit 150 and / or the nutrient output unit 160 calculates the amount of calories and / or nutrients that can be obtained through the food ingested by the user based on the contents input by the user (404). .

When a user inputs contents registered in the menu information database 110 such as a restaurant, menu, and processed food name, the user outputs calories and / or nutrients ingested by the user, and if the user is not a registered restaurant If you have not eaten at another restaurant or have eaten at home, the calories using the average value of calories and / or nutrients of the same menu or food as the menu or food name of the restaurant entered by the user in the menu information database 110 And / or calculate the amount of nutrients.

If the same food name as the food name entered by the user is not registered in the menu information database 110, the user may be notified of this, and it is also possible to receive an amount of calories and / or nutrients expected directly from the user (not shown). ).

The information about the food name and the calculated calories and / or the amount of nutrients thus input is temporarily stored in the user information database 120, and at the same time may be output to the user's wireless terminal (not shown).

The calorie output unit 150 and / or the nutrient output unit 160 calculates the amount of calories and / or nutrients ingested by the user and then calories and / or nutrients to be consumed by the user at the next meal. Compute the amount of (405).

If the user has specifically registered the amount of calories and / or nutrients recommended for him or her, then the user calculates the amount of calories and / or nutrients the next meal should consume; otherwise, the system designer Calculate the amount of calories and / or nutrients using the criteria set by.

If the user's meal is dinner, the amount of calories and / or nutrients the user should consume per day minus the amount of calories and / or nutrients the user already consumed is the amount of calories the user should consume at the next meal and / Or the amount of nutrients will be calculated. If the user's next meal is breakfast or lunch, the amount of calories and / or nutrients to be ingested during the day minus the amount of calories and / or nutrients already ingested is determined by a ratio predetermined by the system designer or user. The division will be calculated as the amount of calories and / or nutrients to be consumed at the next meal.

The menu extracting unit 140 extracts and provides a menu recommended to the user to the user by using the calorie value and / or the amount of nutrients calculated above (406).

When extracting the menu, the user's current location or the user's specific location information is identified and the menu list of nearby restaurants and the restaurant is extracted based on this, and among them, the menu meets the criteria of the amount of calories and / or nutrients calculated previously. A menu can also be extracted and the menu presented to the user.

In addition, a restaurant that receives a menu or a restaurant name first inputted to the user, and is extracted according to the amount of calories and / or nutrients to be consumed at the time of the next calculation among information corresponding to the menu or restaurant name input by the user; Menu names may also be provided to the user.

In the case of extracting the recommended menu, it is preferable to receive an intake amount of food included in the menu from the user in advance so that the menu can be extracted based on this.

For example, if a user pre-sets the stock to consume all the food provided in the restaurant, and the corrosion is to consume only half of the food provided in the restaurant, the user is registered in the menu information database 110 based on this. The recommended menu is extracted by calculating the amount of calories and / or nutrients in each restaurant menu.

When extracting the recommended menus, a menu will usually be extracted that has less calories and / or nutrients than those calories and / or nutrients to be consumed at the time of eating, but is the minimum calorie required by the user. And / or if the amount of nutrients is set, it would be desirable to have a menu with more calories and / or nutrients extracted.

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

As described above, according to the present invention, the present invention does not provide the user with the amount of calories or nutrients on a per unit mass basis, but based on the amount provided in each restaurant, and also for each menu. Because it provides the public can easily know the amount of calories or nutrients through the food they eat, and more efficient diet management is possible.
