The article management system stores an unspecified number of foods 1, acquires a data related to the type and state of the stored food 1, such as the product name, and the like, and transmits the data wirelessly, and this sensor-equipped container 2 A receiver 3 having a light receiving element 14 for receiving data transmitted from the receiver 4 and a database 4 which is connected to the receiver 3 via a home network 13 and stores reference data for determining the type of the article 1; Analyzing device 5 that analyzes the data received by receiver 3 to estimate the type and state of article 1 in container 2, display device 6 that displays the type and state of found article 1, and home network 13 A microwave oven 12 and a refrigerator 11 are provided. The analysis device 5 is provided with a communication device 8 connected to an external data center 9 through a network 7, and the reference data in the database 4 can be updated with data acquired from the data center 9 by the communication device 8. Here, the food 1 is an unspecified number of foods such as fruits and vegetables, meat, and cooked dishes. In addition, the state of the food 1 is information relating to the food such as the amount, type, and deterioration state of the food, that is, freshness.

  The sensor-equipped container 2 can be handled in the same way as a general container. For example, food such as vegetables, meat, and fish, frozen ingredients, prepared ingredients such as boiled vegetables, cooked fish, hamburgers, etc. It is possible to store a large number of unspecified foods 1 such as foods, dishes, and liquid dishes such as curry. When the user purchases food or creates a dish, the food 1 is placed in the sensor-equipped container 2 and stored. Or a food delivery company may put food 1 in container 2 with a sensor beforehand, and may deliver it to a user's house. Moreover, the container 2 with a sensor is used also as what heat-cooks by putting in the cooking appliances, such as the microwave oven 12, after putting and storing in the refrigerator 11 in the state which accommodated the foodstuff 1. FIG. Such a container 2 with a sensor can transmit identification information for each individual inside, and a plurality of containers can be used simultaneously in the article management system.

Next, a specific configuration of the sensor-equipped container 2 will be described.
FIG. 2 is a perspective view showing a schematic configuration of the sensor-equipped container 2, in which the container part 22 is sealed with a removable lid part 26. A protective container 21 containing a plurality of sensors for detecting the food name and state of the food 1 is formed inside the container 22, and the surface of the protective container 21 facing the inside of the container 22 has the food 1 Opening guide portions 23a, 23b, and 23c are formed to guide the gas or liquid 15 emitted from the sensor 15 to the sensor element disposed in the protective container 21. One to a plurality of opening guides 23a to 23c are provided according to the number of sensor elements to be used.

  FIG. 3 is a cross-sectional view showing the sensor-equipped container 2 in a state where the lid part 26 is attached to the container part 22 and sealed. An opening transmission part 24 that transmits light for transmitting sensor information is provided on the back surface of the protective container 21 in contact with the container part 22, and the side wall surface of the container part 22 corresponding to the opening transmission part 24 is provided. Also, an opening 25 for transmitting light is provided. Inside the protective container 21 are sensor elements 31a, 31b, 31c that detect physical quantities related to the amount, type, and deterioration status of the food 1, and a control circuit 32 that takes in the outputs of these sensor elements 31a-31c and transmits them wirelessly. A light emitting element 33 which is a transmitting element used for wireless transmission and a power source 34 such as a battery for supplying power to the control circuit 32 are housed.

  The protective container 21 is formed of a conductor and functions as a shield for shielding electromagnetic waves from the sensor elements 31a to 31c. Cylindrical shields 35a, 35b, 35c, and 36 are provided on the inner walls of the opening guide portions 23a to 23c and the opening transmitting portion 24 formed on the surface side facing the inside of the container portion 22 in the protective container 21, respectively. Seals 39a, 39b, 39c for sealing gas and liquid are inserted between the cylindrical shields 35a-35c facing the sensor elements 31a-31c and the sensor elements 31a-31c, respectively. A light transmission window 37 made of a transparent resin or the like is provided in the opening transmission part 24 facing the light emitting element 33, and the same applies to the opening transmission part 25 on the side wall surface of the container part 22 corresponding to the light transmission window 37. The light transmission window 38 is provided.

  As can be understood from this description, all the openings formed in the protective container 21 and the container part 22 are sealed, so that the gas or liquid 15 emitted from the food 1 stored in the container part 22 is not deep inside the protective container 21. The control circuit 32, the light emitting element 33, and the power source 34 can be protected from these. Moreover, since water does not permeate into the inside of the protective container 21 with the same configuration, the entire sensor-equipped container 2 can be washed with water, and the food contained in the sensor-equipped container 2 can be changed and used repeatedly. become able to.

  Here, the sensor element 31a is a gas sensor capable of detecting the gas concentration of the gas emitted from the food 1 for each type of gas, and the sensor element 31b is the concentration of ions contained in the liquid 15 emitted from the food 1 for each type of ion. The ion sensor and sensor element 31c that can be detected are pressure sensors that detect the pressure of gas in the container. As will be described in detail later, the sensor elements 31a and 31b are used as a type sensor and a deterioration state sensor for detecting the type and deterioration state of the food 1 by combining them, and the sensor element 31c detects the amount of the food 1 It is used as a quantity sensor.

  As the sensor element 31a, for example, a semiconductor type gas sensor that detects a change in electric resistance due to gas being adsorbed on a thin film is used, and the types of gases detected thereby include alcohol, ester, ethylene, carbon dioxide, aldehyde, and sulfur. , Ammonia and the like. Moreover, as the sensor element 31b, for example, an ion sensor using an ion selective field effect transistor (Ion-Selective Field Effect Transistor (ISFET)) is used, and the types of ions detected thereby are hydrogen, sodium, potassium, Such as calcium. Furthermore, as the sensor element 31c, for example, a pressure sensor using a piezoelectric element is used.

  Here, the above-described three sensor elements 31a to 31c are mounted. However, other sensors such as an odor sensor, a temperature sensor, a humidity sensor, a pressure sensor, a weight sensor, and a color sensor may be mounted. They may be any number of one or more. When mounting a plurality of sensor elements, an opening guide is provided in the protective container 21 for each sensor element. However, when the sensor element is small, the plurality of sensor elements are exposed in one opening guide. Also good.

  The positions of the opening guide portions 23a to 23c of the protective container 21 may be determined according to objects to be detected by the sensor elements 31a to 31c. That is, in the case of a pressure sensor or a gas sensor that detects lighter gas than air, an opening is provided at a height close to the upper surface of the container 22 to detect a gas sensor that detects heavier gas than air or liquid ions. In the case of an ion sensor, an opening may be provided at a position close to the bottom surface of the container portion 22. When it is not necessary to arrange these sensor elements at low positions, the protective container 21 may be attached to the lid 26.

  As for the gas sensor and pressure sensor for detecting gas, the opening of the protective container 21 may be closed with a selectively permeable membrane that transmits gas and blocks liquid and solid. In this way, the response speed of detection becomes slow, but the sensor is protected and cleaning becomes easy.

  As described above, the sensor-equipped container 2 is also used for cooking by heating in a microwave oven. However, in the microwave oven, high-power electromagnetic waves (microwaves) are used to heat food, and the sensor element 31a. , 31b, 31c and the control circuit 32 receive this microwave, the sensor output may fluctuate, causing detection errors or destroying the element. However, the sensor-equipped container 2 can be used in the microwave oven by the electromagnetic wave shield made of the material of the protective container 21, the opening guide portions 23 a to 23 c and 24, and the cylindrical shields 35 a to 35 c and 36.

  That is, in order to block the microwave, the protective container 21 is formed of a conductor and functions as an electromagnetic wave shield. In addition, there are opening guide portions 23a to 23c and 24 on the opposing surfaces of the sensor elements 31a to 31c and the light emitting element 33 in the protective container 21, and the diameters of the opening guide portions 23a to 23c and 24 are set in order to prevent microwaves from entering. It can be made sufficiently smaller than the wavelength of the electromagnetic wave. In general, in a microwave oven, an electromagnetic wave having a frequency of 2.45 GHz and a wavelength of 12 cm is used. Therefore, it is desirable that the diameters of the opening guide portions 23a to 23c and 24 be 3 mm or less. Further, cylindrical shields 35a to 35c and 36 are arranged on the inner wall surface to further enhance the shielding effect. As described above, when a vertical conductor such as a cylindrical shape is provided in the opening guide portions 23a to 23c and 24, intrusion of electromagnetic waves from the opening guide portions 23a to 23c and 24 is greatly reduced. In order to obtain this sufficient shielding effect, it is desirable that the height of the wall surface be one or more times the diameter of the opening guide.

  The receiver 3 shown in FIG. 1 includes a light receiving element 14 that receives an optical communication signal from the sensor-equipped container 2, and is installed near a place where the sensor-equipped container 2 is used. For example, it may be arranged in a kitchen, in the refrigerator 11, or in a cooking utensil such as the microwave oven 12.

  In the database 4 shown in FIG. 1, a standard value of data obtained from the type sensor is recorded as reference data for each type of food. In addition, reference data in a plurality of different deterioration situations is recorded for each food type.

  The analysis device 5 searches the database 4 based on the received type sensor data and extracts the most similar reference data to determine the type of food. In addition, the amount and deterioration state of the food are estimated based on the data and reference data of the amount sensor and the deterioration state sensor. Information on the amount, type, and deterioration status of the obtained food is transmitted to the display device 6 provided on the door of the refrigerator 11 through the home network 13 and displayed. Moreover, the analysis apparatus 5 calculates | requires the quantity and the kind of the foodstuff 1 in the container 2 with a sensor put in the microwave oven 12, and instruct | indicates an output and heating time to the microwave oven 12 through the home network 13 based on it. Appropriate cooking is done.

  As described above, the article management system of the present invention obtains at least a container 2 with a sensor that stores at least an unspecified number of foods, and type information of the food that is disposed in the container 2 with a sensor and stored in the container 2 with a sensor. A classification sensor, a wireless transmission means for transmitting information of the classification sensor, a receiver 3 for receiving the classification sensor, and an analysis device 5 for determining the type of food based on the data of the classification sensor received by the receiver 3. Therefore, even if the container 2 with a sensor is used repeatedly, it is possible to determine the type of food without manually inputting the type of food stored in the container 2 and to efficiently manage articles. be able to.

Next, a health management system that provides health advice will be described.
In this health management system, the age, sex, height, weight, etc. of each person in the family are input to the analysis device 5 as information on the family structure of the user's house in advance. This analysis device 5 keeps track of how much of each type of food is consumed by recording the amount and type of food 1 stored in the sensor-equipped container 2 using the article management system 1 described above. Then, it is determined whether or not the ingested nutrition is appropriate from the information on the consumption state of the food and the family structure, and displayed on the display device 6.

FIG. 4 is a front view of the display device 6 showing a display example.
The radar chart 40 by the analysis device 5 displays the balance of nutrients such as calories (energy), proteins, lipids, sodium, calcium, iron and vitamins. The reference circle 41 of the radar chart 40 corresponds to an appropriate amount of each nutrient in the inputted family structure. When each vertex of the radar chart is in the reference circle 41, nutrition is insufficient, the reference When it is outside the circle 41, it indicates that nutrition is excessive. The management device 5 uses the stored food and generates a menu with a good nutritional balance using the information on the amount and type of the food collected from the sensor-equipped container 2, and the menu of the display device 6. If there is a food to be purchased that is displayed on the display unit 42 and is insufficient to create the menu dishes, the purchase list 43 is displayed on the display device 6. Thereby, a health service can be provided without taking time and effort to the user.

FIG. 5 is a cross-sectional view showing the structure of the amount detection means for detecting the amount of food 1.
The container 2 with a sensor for containing the food 1 is made of a flexible material by changing the configuration of the lid portion 26 shown in FIG. 3, and a pedestal 51 and a lock button as a lock mechanism are formed on the lid portion 26. 52, and a check valve 53 that allows gas to pass only from the inside of the container portion 22 to the outside of the container portion 22 is provided in the lid portion 26. The protective container 21 built in the container part 22 is provided with a pressure sensor that can detect the pressure of the space in the container part 22. When the lock button 52 is pressed in the state of FIG. 5, the lid portion 26 is bent as shown in FIG. 6, and the volume of the container portion 22 changes by a certain amount. That is, the lock button 52 also serves as a volume change imparting unit that changes the volume of the container portion 22.

  This container 2 with a sensor is used as follows. First, the user opens the lid part 26, puts the food 1 into the container part 22, and closes the lid part 26 as shown in FIG. Next, the user pushes the lock button 52 as shown in FIG. 6 in order to fix the lid portion 26. Then, the lid portion 26 is bent and the volume in the container portion 22 is reduced, so that the check valve 53 is opened and a certain amount of air 54 is discharged. Thereafter, the user releases his / her hand from the lock button 52 as shown in FIG. Then, the cover part 26 returns to its original shape due to elasticity, and the volume in the container part 22 also returns to its original size. However, since air cannot flow into the container portion 22 by the check valve 53, the pressure in the container portion 22 decreases. As a result, the lid portion 26 comes into close contact with the container portion 22 and the lid portion 26 is fixed. At the same time, the amount of change in the pressure in the container portion 22 depends on the volume of the space in the container portion 22. Therefore, the volume of the food 1 can be calculated | required using it.

  This is expressed by the following formula. The volume of the container 22 is V, the volume of the food 1 in the container 22 is Q, the volume decrease of the container 22 by pressing the lock button 52 is ΔV, the atmospheric pressure is P, and the lock button 52 is released. Let the pressure decrease amount be ΔP. When the lock button 52 is pressed, the pressure in the container portion 22 is P, and the volume of the space in the container portion 22 is (VQ−ΔV). When the lock button 52 is released, the pressure becomes (P−ΔP) and the volume becomes (VQ). There is no change in the mass of the gas between when the lock button 52 is pressed and when it is released, so the product of pressure and volume is constant if the change in temperature is ignored. Therefore, P × (V−Q−ΔV) = (P−ΔP) × (V−Q) holds.

  When this is solved for the volume Q of the food 1, a relationship of Q = V−P × ΔV / ΔP is obtained. Since the volume V, the atmospheric pressure P, and the volume reduction amount ΔV of the container portion 22 are known in advance, the volume Q of the food 1 can be calculated by detecting the pressure reduction amount ΔP with a pressure sensor and substituting it into the above equation. it can.

  The calculation described above is performed by the control circuit 32 in the protective container 21. The pressure decrease amount ΔP can be obtained by comparing the output of the pressure sensor when the lock button 52 in FIG. 6 is pressed and when the lock button 52 in FIG. 7 is released. The release of the lock button 52 may be detected by utilizing the sudden drop in the output of the pressure sensor. Alternatively, it is possible to detect that the lock button 52 has been released by providing a switch for detecting the operation in the vicinity of the lock button 52 and transmitting an ON / OFF signal of this switch to the control circuit 32. In that case, if the protective container 21 is provided in the cover part 26, a structure will become easy.

  With such a configuration and calculation method, the operation of closing the lid portion 26 also serves as an operation for giving a volume change for volume measurement, so that the food 1 is closed each time the lid portion 26 is closed without taking time and effort to the user. The volume of can be measured. The sensor-equipped container 2 can also be used in an article management system.

FIG. 8 is a block diagram showing the entire health management system configured by applying the food management system.
The gas concentration sensor 31a and the ion concentration sensor 31b provided in the protective container 21 in the sensor-equipped container 2 are the food 1 in the container part 22 through the openings 23a and 23b of the protective container 21 shown in FIG. In contact with gases and liquids emanating from The gas concentration sensor 31a detects the gas concentration for each type of gas contained in the gas, converts it into an electrical signal, and outputs it. The ion concentration sensor 31b detects the ion concentration for each type of ions contained in the liquid, converts it into an electrical signal, and outputs it. Upon receiving these outputs, the control circuit 32 converts the output signals of the gas concentration sensor 31a and the ion concentration sensor 31b into digital signals and takes them in.

  Moreover, the pressure sensor 31c provided in the protective container 21 contacts the air in the space in the container part 22 through the opening guide part 23c of the protective container 21, converts the pressure into an electric signal, and outputs it. The control circuit 32 takes in the output signal of the pressure sensor and obtains the volume of the food 1 in the container portion 22 by the method described with reference to FIGS. The control circuit 32 adds the container identification number 63 to the data of the gas concentration sensor 31 a and the ion concentration sensor 31 b and the volume data of the food 1, drives the issuing element 33, and transmits the data by the optical signal 62. Here, since light is used as the communication means, reliable communication can be performed even inside the microwave oven irradiated with high-power microwaves.

  The receiver 3 receives the optical signal 62 by the light receiving element 14 and transmits the reception data 61 to the analysis device 5. Here, since the optical signal 62 emitted by the light emitting element 33 is reflected by the wall of the kitchen, refrigerator, or microwave oven in which the receiver 3 is installed, there is no need for the light receiving element 14 and the light emitting element 33 to face each other. The attached container 2 can be placed in any direction. The analysis device 5 that has received the reception data 61 extracts the data 64a of the gas concentration sensor 31a, the data 64b of the ion concentration sensor 31b, the volume data 64c of the food 1 and the container identification number 65 from the received data 61.

  Next, the type determination unit 66 of the analysis device 5 analyzes the gas concentration data 64a and the ion concentration data 64b to determine the type of the food 1 stored in the sensor-equipped container 2. Specifically, the reference data for each food type stored in the database 4 is searched to extract the most similar to the received gas concentration data 64a and the ion concentration data 64b. It determines with having accommodated in the container 2 with a sensor. If reference data similar to the received data is not registered in the database 4, the latest reference data is downloaded to the database 4 by connecting to the external data center 9 via the communication device 8 and the network 7. Search again. As a result, even a new type of food can be identified.

  Moreover, the deterioration condition determination part 67 of the analyzer 5 analyzes the gas concentration data 64a and the ion concentration data 64b, and calculates | requires the deterioration condition of foodstuffs. For this purpose, for example, a characteristic that ammonia-based gas is generated or the acidity of the liquid is increased when the vegetables deteriorate is used. Further, the weight determination unit 68 of the analysis device 5 multiplies the volume by the specific gravity according to the type of food based on the received volume data 64c and the food type obtained by the type determination unit 66, thereby obtaining the amount of food. Find the weight of the food.

  In addition, the data analysis unit 69 of the analysis device 5 identifies the container 2 with the sensor that transmitted the data by the container identification number 65, and collects information on the weight, type, and deterioration status of the food stored in each container. Then, it is transferred to the display device 6 and displayed as a list. When the food 1 is deteriorated, a warning is given by blinking the display. As a result, it is possible to collect information on the amount, type, and deterioration status of all the stored foods without compromising registration. In addition, since the display is sequentially updated based on the received data 61 received from the sensor-equipped container 2, the display automatically changes even when the contents are replaced or the deterioration state changes, and the state of the food can be changed without much trouble. It can be monitored constantly.

  In the embodiment described above, an example of managing food as an article to be managed has been shown. However, instead of food, other articles such as medical test samples such as blood, medicines, and industrial materials may be managed. Moreover, in embodiment mentioned above, although the battery is used as the power supply 34 which drives the control circuit 32 of the container 2 with a sensor, instead of other power supplies, for example, a microwave is received out of the protective container 21. An antenna may be provided and microwave energy irradiated from a microwave oven may be received and used as a power source. Moreover, you may supply electric power using the vibration generated from a refrigerator etc. using the vibration generator which converts vibration energy into electricity.

  In the above-described embodiment, optical communication is used for data transmission from the wireless sensor. However, instead of optical communication, communication using sound waves or radio waves may be used. When sound waves are used, a speaker and a microphone are used instead of the light emitting element and the light receiving element.
