Recently, thanks to the development of IT technology, electric, electronic and communication technologies have been applied to various household goods. Especially, as the concepts of Internet of Thing (IoT) and Ubiquitous Sensor Network are spreading, various information is gathered without any time and place, and a method to utilize the collected information There are many discussions about Here, the Internet refers to a technology or environment in which a sensor is attached to an object to exchange information with the Internet in real time. And ubiquitous sensor network refers to communication network that recognizes objects and environment by attaching electronic tags to all objects and constructs and utilizes real-time information through network. In particular, the concept of the Internet of things and the ubiquitous sensor network has been actively used in the process of developing convenience and convenience in everyday life or managing the health of the people, .

According to the Internet of Things and the Ubiquitous Sensor Network, everything we can think of can be connected to the network. In addition, a pen, a toothbrush, and the like can be connected to the network, and information such as information on a person using the object and a pattern in which the object is used can be generated and shared. Now that public interest in health and safety is higher than ever, the Internet or ubiquitous sensor networks can be applied to various health and safety related objects.

Diet, on the other hand, is a health issue that many people are interested in, regardless of the country. Diet has been on the market for the first time since 20 ~ 30 years ago, and various researches have been going on until now. This is related to the quality of life and can be interpreted as a reflection of the desire of people to lead a better life through health care.

In recent years, various methods have been developed to manage health by using "healthy eating habits", which take good food to the body in various ways, and light exercise, rather than simple weight control through exercise. People refer to various health care laws that are shared through books and internet sites, or they control exercise and amount of food according to the programs suggested by the gymnasium. However, this is a general health management method so far.

IT technology has already had a big influence in our daily life, but it is not beyond the rudimentary level only in the toxic health related field. This is because the Internet or the ubiquitous sensor network has not yet been established in our society.

Recently, a number of health care band products including various sensors such as an acceleration sensor have been released. The product simply recognizes the movement state of the wearer and transmits it to a nearby smart device. to be.

As mentioned earlier, not only exercise but also 'what to eat' is important, and there is no IT product related to it yet. In relation to eating habits, people either roughly determine their intake from the amount of food contained in the bowl, or refer to the nutrients indicated on the outside of the packaged food. In other words, it is not easy to objectively grasp how much someone has eaten, and it is not easy to systematically record or manage it.

In addition, the method of grasping the smell or observing the appearance is mainly used in the method of grasping the state of the foodstuff prepared or prepared at the table for storage or eating. However, there are cases where the above two methods can not confirm whether or not the food has been damaged, and it is difficult to confirm how long the food was stored.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a smart tableware that grasps the state of foods contained in smart dishes and informs the user of the states of the foods.

The present invention relates to a smart tableware and a control method thereof for detecting a state of foods contained in a smart table and providing the user with information on the degree of decay of food and the amount of heat contained in the food, and a control method thereof. An example will be described in detail.

1 is a view showing a smart table 100 according to an embodiment of the present invention.

1, the smart tablet 100 according to the present invention may include a sensing unit 110, a communication unit 120, a control unit 130, and an output unit 140.

The sensing unit 110 senses the state of food contained in the smart dish 100. Here, the state of the food may include, but is not limited to, the volume and weight of the food, the degree of decay of the food, the amount of heat contained in the food, the nutrients contained in the food, and the salinity of the food. The sensing unit 110 may include various sensing means for sensing the state of the food. The sensing unit 110 may include a weighing module 112, a corruption sensing module 114, a salinity measurement module 116, and a temperature measurement module (not shown).

The weight measuring module 112 measures the weight of the food contained in the smart table 100. The weight measuring module 112 may be provided as an electronic scale installed under the smart table 100, but is not limited thereto. The weight measurement module 112 can continuously measure changes in the weight of the food. That is, the weight of the food may be changed by the user taking the food in a state where the food is contained in the smart table 100. The weight measuring module 112 measures the weight of the food in the initial state, Weight can be measured, and weight change of food can be measured separately. The weight change information of the food is transmitted to the controller 130 to be described later, and the controller 130 can analyze the weight of the food consumed by the user.

The corruption detection module 114 detects the degree of corruption of the food. Foods are subject to corruption at different rates depending on the surrounding temperature, and corruption can also be caused by ingredients such as saliva. In addition, even if there is no change in the environment of the food, the continuous contact with the air may lead to corruption according to the passage of time, and the microorganism may multiply rapidly during the course of corruption, or a specific chemical component may be produced or extinguished.

Normally, food corruption can be detected through the appearance and color of the food, and the smell and taste. This method can give a physiological dislike to the person who confirms corruption, and can be harmful by the toxicity contained in the corrupted food, especially if it tastes directly. In some cases, the corruption of the food may not be displayed in the appearance of the food.

Corruption detection module 114 may detect the degree of corruption of food from objective measurements on behalf of a person. Corruption detection module 114 may be provided in various manners. When the food is fish or meat, the content of the chemical component including the amine increases when the decay starts, and the detector for detecting the amine component may be used as the corruption detection module 114. Alternatively, in one embodiment of the decay detection module 114, a detector may be used that detects the ammonia produced as the amine component changes. Meanwhile, the amount of microorganisms is rapidly increased as the food is decayed. The decay detection module 114 may detect the microorganisms or detect components such as carbon dioxide and toxins produced by the microorganisms. However, the corruption detection module 114 is not limited to the above-described method.

The salinity measurement module 116 may measure the salinity of food contained in the smart dish 100. Salinity is also referred to as salinity, and the total amount of salts contained in 1 kg of water is expressed in g (grams). Salinity is an essential ingredient for a person to survive, but excessive salt intake can cause hypertension, kidney disease and heart disease. Especially, in Korea, most people are directly exposed to this disease, and recently, they are trying to reduce their salt intake by reducing the use of seasonings such as salt or eating them lightly. By including the salinity measurement module 116 in the smart tablet 100 according to the present invention, the smart tablet 100 can accurately measure the amount of salt contained in the food. Through this, the user can check the amount of salt he or she has ingested, systematically record the salt amount, and effectively manage the user's health.

In general, salinity is closely related to the electrical conductivity of an object containing saline. The salinity measurement module 116 may sense the salinity of the food by measuring the electrical conductivity of the food, but is not limited to this method.

The temperature measurement module can measure the temperature inside and outside of the smart table 100. Foods differ in the temperature at which they taste best, and the temperature they should keep when storing each food is different. In addition, the shape of the food may vary depending on the temperature. For example, when iced foods are kept at room temperature, they may melt and change into a liquid state. In this case, the iced foods may not be corroded but may be determined to be difficult to ingest.

As mentioned above, temperature is closely related to food. The smart dish 100 according to the present invention can measure the corruption state of the food according to the temperature and the possibility of ingesting the food by providing the temperature measurement module.

The temperature measurement module can be implemented in various ways. Preferably, the electronic thermometer may be equipped with an electronic thermometer using an element whose electric resistance value changes according to a change in temperature, but the present invention is not limited thereto.

The communication unit 120 can transmit and receive information to and from the external terminal. Information such as weight, degree of corruption, salinity, and temperature of the food measured by the sensing unit 110 may be transmitted to the external terminal through the communication unit 120. Alternatively, the communication unit 120 may receive information on the kind of food, information on the amount of heat of the food, and nutritional information on the food from the external terminal. However, the information that the communication unit 120 can transmit / receive is not limited thereto. The communication unit 120 receives the information generated in the external terminal, so that the smart tablet 100 can use the information in the internal calculation process. As described above, the smart tablet 100 includes the sensing unit 110 and the communication unit 120 so that the smart Internet 100 and the ubiquitous sensor network can be configured. The information generated by the smart tablet 100 can be shared through a network such as the Internet And the information on the network can be transmitted to the smart tablet machine 100.

The external terminal for transmitting and receiving information to and from the communication unit 120 may be preferably provided as a digital device such as a smart phone or a PC, but is not limited thereto. Also, the communication unit 120 can transmit and receive information wirelessly with an external terminal, but can also perform communication via a wire. Preferably, the communication unit 120 may perform communication through a method such as BLE (Bluetooth Low Energy) and ZigBee which have low power consumption, but the present invention is not limited thereto.

The control unit 130 may control the operation of each part of the smart table 100. It is possible to perform an operation on the information measured by the sensing unit 110 and the information received through the communication unit 120 and to generate the processing signals of each subunit based on the calculation result. Also, the controller 130 may generate the food state information based on the information measured by the sensing unit 110.

The control unit 130 receives the type information of the food and the calorie information of the food from the external terminal through the communication unit 120 and transmits the weight information of the food measured by the weight measurement module 112 of the sensing unit 110, The calorie information of the food contained in the smart table 100 can be calculated by referring to the calorie information. Then, the calculated calorie information can be output through the output unit 140. The calorie information of the food may be transmitted to an external terminal through the communication unit 120. The user of the smart tablet machine 100 can control the degree of his / her eating and calorie intake by referring to the calorific information output from each smart tablet machine 100. The user can easily check the total calories of the food prepared at each meal from the calorie information transmitted from the plurality of smart dishes 100. [

As described above, the sensing unit 110 can measure the weight change of the food. The control unit 130 senses a change in the weight of the food of the food through the sensing unit 110, calculates the amount of heat contained in the food consumed by the user based on the weight change and the calorie information, The user can display the amount of calories consumed by the user. The calorie information consumed by the user may be transmitted to an external terminal through the communication unit 120. For example, the user can receive the type information of the food and the calorie intake calories generated by each smart appliance 100 with his smartphone. The user of the smart tableware 100 can easily confirm the total calories of the food and the calories consumed in the smart tableware 100 and manage his / her health smoothly by referring to the calories.

Meanwhile, the communication unit 120 can receive the nutritional information of the food from the external terminal. The control unit 130 senses a change in the weight of the food through the sensing unit 110 and receives the nutritional information included in the food from the external terminal through the communication unit 120, The amount of nutrients contained in the food consumed by the user can be calculated. The control unit 130 may output the amount of the nutrient component consumed by the user through the output unit 140 or may transmit the amount of the nutrient component to the external terminal through the communication unit 120. The user of the smart tableware 100 can easily confirm the information of the nutrition component he / she has ingested and can discriminate the nutrition component he / she is over-consuming and the nutrition component which is consuming less.

The performance of the controller 130 may be lowered in order to lower the manufacturing cost of the smart tableware 100 or to design the low power when the smart tableware 100 is manufactured. In this case, the computing ability of the control unit 130 may become a problem. However, the control unit 130 may transmit the weight information of the food measured by the sensing unit 110 to the external terminal through the communication unit 120, and the external terminal may calculate the amount of heat and nutrients based on the weight of the food, And then sent back to the smart tableware 100. The control unit 130 may perform a simple form of receiving the information through the communication unit 120 and outputting the received information through the output unit 140. [

The control unit 130 may determine whether the food is corrupted or not through the sensing unit 120. If the food is determined to be corrupted, the control unit 130 outputs information indicating that the food is corrupted through the output unit 140 Or may be transmitted to an external terminal through the communication unit 120. The user can distinguish the corrupted food through the information, and can efficiently utilize the storage space of the refrigerator or the like by rapidly processing the food.

The control unit 130 may measure the time at which the food is first stored in the smart table 100 through the sensing unit 110 and the elapsed time from that time. More specifically, the control unit 130 can detect a change in weight due to the storage of food through the weight measurement module 112 of the sensing unit 110, and record the time when the weight change occurs. However, the manner in which the control unit 130 confirms the time is not limited thereto. The control unit 130 can determine whether the food is corrupt or not based on the food type information received through the communication unit 120 and the elapsed time information. The control unit 130 may output at least one of the time of the food, the elapsed time, the degree of corruption of the food, and the possibility of ingestion through the output unit 140 or may be transmitted to the external terminal through the communication unit 120 have.

Some foods, if stored for a long time, can be transformed into a state that is not decayed but difficult to ingest. For example, a case of storing bread in a smart dish 100 and storing it in a refrigerator can be considered. In case of bread, it can be stored at a low temperature for a relatively long time. However, since the moisture of bread is lost over time, . ≪ / RTI > The control unit 130 can determine that the food contained in the smart table 100 is bread and the storage period has passed 15 days and that the state of the bread is now in a state where it is difficult to eat, To the communication unit (120) or the output unit (140). Alternatively, the control unit 130 may transmit a signal to the communication unit 120 and the output unit 140 when the bread is stored for five days. The user can confirm the time and storage time of the food stored in the output unit 140 of the smart dish 100 or the output unit of the external terminal used by the user and can easily check the state of the food. Thus, the user can perform the storage management of the easy food.

On the other hand, the control unit 130 continuously detects the change in the weight of the food and the change in the weight of the food through the sensing unit 110, and determines the amount of change in the weight of the food, So that the user's food intake pattern can be analyzed. The control unit 130 may transmit the food intake pattern to the external terminal through the communication unit 120. [ The control unit 130 may output the food intake pattern information through the output unit 140 of the smart dish 100. The user can easily check his / her eating habits from accumulated food intake pattern information and utilize the information in the health management of the user.

The controller 130 may control the temperature of the sensing unit 110 and the temperature of the food to be exposed to the temperature change, Time information, and determine whether the food is corrupt or not based on the analyzed information. The control unit 130 can output at least one of the time of the food, the elapsed time, the food corruption, and the possibility of ingestion through the output unit 140 or the external terminal through the communication unit 120 . As described above, food is closely related to temperature, and the state of food may change depending on the temperature at which food is exposed. The control unit 130 can inform the user of the state of the food by determining the change in the temperature applied to the food.

If the sensing unit 110 further includes a salinity measuring module 116 for measuring the salinity of the food, the controller 130 may determine the type of food received through the communication unit 120, Based on the measured food weight information and salinity information, it is possible to analyze the content of salt contained in the food contained in the smart table 100 and whether the salt content is excessive. The control unit 130 may output the salt content information and whether or not the salt content is excessive through the output unit 140. The user can easily identify the salt contained in the food from the information on the salt content and the information on the presence or absence of excessive salt, thereby protecting the self from various diseases by controlling the salt intake.

The output unit 140 may output information according to a processing signal of the control unit 130. [ The output unit 140 outputs information such as the weight of the food, the amount of heat contained in the food, the nutrient content, the salinity, the temperature inside and outside the smart table 100, the degree of decay of the food, can do. However, the information that the output unit 140 can output is not limited thereto. The output unit 140 may output the information in a manner such as vibration using light, sound, or power. Preferably, the output unit 140 may include an LCD panel or an LED bulb. However, the output unit 140 may be variously implemented and is not limited thereto.

The smart tablet machine 100 may include a power supply unit (not shown) for supplying power to each unit, and the power supply unit may further include a solar cell module (not shown) for generating power from light.

The smart tableware 100 can be configured through a combination of the above-described components. In particular, the sensing unit 110 of the smart tablet 100 may be provided in various configurations. The sensing unit 110 including only the corruption sensing module 114 may be used according to the purpose of the smart tablet 100. Alternatively, the smart tablet 100 according to the present invention may include a sensing unit 110, a communication unit 120, and a control unit 130 including only a weight measurement module 112. In this case, the user can check the food state information transmitted through the communication unit 120 of the smart dish 100 from his / her own smartphone, and the related calorie and nutrient intake information have. The configuration of the smart table 100 is not limited thereto and can be freely configured according to the intention of the person practicing the present invention.

FIG. 2 is a diagram illustrating an object Internet environment 1000 including a smart appliance according to an embodiment of the present invention.

2, the object Internet environment 1000 is constructed through a plurality of smart dishes 100a, 100b, 100c, 100d, 100e, and 100f containing various foods and an external terminal 200 communicating with the plurality of smart dishes. . As shown in FIG. 2, the smart utensils 100a, 100b, 100c, 100d, 100e, and 100f may be manufactured in various shapes such as a plate, a hexahedron, or a cylindrical pail. In FIG. 2, the five smart tables 100a, 100b, 100c, 100d and 100e on the left side are stacked in a storage space a such as a refrigerator and one smart table 100f on the right side is in an open space b ). Each smart tablet can be distinguished by unique identification information.

The user of the smart tableware can grasp the state of food contained in each of the smart utensils 100a, 100b, 100c, 100d, 100e and 100f through the output units 140a, 140b, 140c, 140d, 140e and 140f, Or via an external terminal 200 such as a portable smart phone. In particular, the user need not access the storage space (a) to open the door to check the state of food stored in the storage space (a). The user can remotely check the state of food and storage period in the storage space a by operating the external terminal 200 only. On the other hand, the user can immediately check the degree of decay, calories, nutrients, and salinity information of the food by bringing the food into the smart dish 100f at the meal time. When the user consumes the food, the type information of the food consumed by the user, the calories and the nutrition information are automatically transmitted to the external terminal 200 and recorded. The user can immediately grasp his / her eating habits and nutritional status through his / her external terminal 200 at any time, which is very useful for health care.

Food status information, calories, nutrients, and salinity information can be shared within the network range allowed by the user. For example, the information can be shared by a family member's web site or a closed SNS community, thereby easily grasping the health status of all the family members. Each family member can access the information in the application of the external terminal 200 or in the online meeting space.

Since the smart tablet and the external terminal 200 are connected through a network, they can communicate with each other even if they are not in the same place, and the information held by each device can be freely transmitted and received. For example, a user who is a housewife can instantly grasp the status of food items of the smart dishes 100a, 100b, 100c, 100d, 100e, and 100f through the external terminal 200, You can shop by purchasing only food. Alternatively, the user can immediately check the nutritional components of the family members that are insufficient, and can prepare food for supper at dinner.

In addition, the user can control the operation of the smart table through the external terminal 200. [ For example, when it is difficult to grasp a smart table containing a food desired to be found by a user among the plurality of smart tables, the user may operate the external terminal 200 to output light or sound Output. The control of the operation of the smart table through the external terminal 200 is not limited thereto and can be performed in various ways.

On the other hand, there is no means to immediately distinguish the many kinds of foods that exist in the world. It is possible to consider the kind of beverage by analyzing the composition of the liquid, but it is literally limited to the beverage, not the entire food, and the kinds of beverages that can be distinguished are also very limited. Alternatively, a method of discriminating the type of food through image pattern analysis using the food database and the image capturing means can be considered. However, it is technically impossible to apply the above configuration to a relatively small and inexpensive product called a tableware. Therefore, it is necessary for the user to input the type information of the food contained in the smart table to the external terminal 200 and to transmit the food type information to the smart table. However, it is not necessary for the user to directly input all the calorie and nutrient information according to the type of food, and the related information is received from the third terminal or the Internet server connected to the external terminal 200 via the network, . If the user uses a specific smart table in a manner to store only the predetermined food, it is limited to transmit the food related information to the smart table from the external terminal 200 for the first time, and the type of the food The smart tableware does not need to receive additional food-related information unless changed. However, the method of using the smart tableware is not limited thereto.

3 is a view showing information output from the output unit 140 of the smart tablet 100 according to the embodiment of the present invention. In FIG. 3, the output unit 140 of the smart tablet 100 is shown as an LCD panel, but the present invention is not limited thereto. The output unit 140 may be provided in various forms.

3 (a) shows basic information of the smart table output by the output unit 140, and can display the smart table identification code, the type of food, the initial storage time, the storage period of food, the degree of food spoilage, and the saltiness. FIG. 3 (b) shows additional information of the smart table output by the output unit 140, and can display the amount of heat of the food, the weight of the food, and the amount of heat consumed by the user. However, the information displayed through the output unit 140 is not limited thereto, and the output unit 140 may additionally include a nutrient component of the food, a nutrient component consumed by the user, a temperature inside or outside the smart table, Can be output.

The user can easily switch between the basic information screen (Fig. 3 (a)) and the additional information screen (Fig. 3 (b)) by touching the output unit 140 by hand or pressing a button etc. provided outside. Through this, information such as the state of the food, the calorie of the food, and the calorie consumed by the user can be checked quickly.

The user can check the same information as that output on the smart table through the external terminal.

4 is a diagram illustrating Smart Tableware-related information output through the output unit 240 of the external terminal. The user can integrally manage a plurality of smart dishes through an external terminal equipped with a smart phone or the like, and can easily check the status of food stored in each smart appliance.

FIG. 4 (a) shows a state in which all the smart dishes are connected to the external terminal through the network. The user confirms the identification code of each smart appliance and the type of food stored in the smart appliance, the storage start time, the storage period, the degree of decay of the food, and the weight of food in the main screen 242 of the external terminal output unit 240 But is not limited thereto. The user can operate the screen turn operation button 244 of the external terminal 240 with a finger or the like to confirm information of other smart tableware which is not displayed on the screen. Although not shown in the figure, the user can check the details of each information through a touch or the like using a finger, and can also check information such as the amount of heat, nutrients, and salinity included in the food. Also, the user can control the operation of each smart tablet by operating the output unit 240 of the external terminal. For example, the user can stop the operation of the smart tablet corresponding to the smart tablet identification code 003. Then, the user can change the food type information by operating the output unit 240 of the external terminal, and can transmit the caloric value and nutrient component information received from another Internet server or the like to each smart table.
