As shown in FIG. 1, the system includes a server 100, a measuring apparatus 200, and a user terminal 300. Server 100 is connected to measurement device 200 and user terminal 300 via network 400. In FIG. 1, only one server 100, one measuring device 200, and one user terminal 300 are shown for simplicity of explanation, but it goes without saying that there may be more than that. In addition, the specific device of the user terminal 300 is not limited to a smartphone as illustrated, and may be a mobile terminal, a tablet terminal, a personal computer, or other electronic devices, for example. Furthermore, the system may use a cloud service (including both public cloud and private cloud), or may provide a service by physically providing a shared or dedicated server in the target facility.

The user terminal 300 is equipped with an application (hereinafter referred to as a “health monitoring app”) that displays health condition monitoring results (including analysis results and estimation results) that are a part of the health monitoring system according to an embodiment of the present invention. As shown in FIG. 3, it is possible to check the health status of the user by viewing the display of the health monitoring application.

As an example, as shown in FIG. 3, the health monitoring system 500 installs a measuring device 200 in an existing toilet or the like, and measures fluid information regarding the fluid in the stored water into which the urine of the user of the toilet flows into the measuring device 200. Then, based on the fluid information measured in the server 100, the urination is analyzed by analyzing a fluid model obtained by modeling the region in which the fluid flows. Based on the urination information of the analyzed urination, the disease of the user Can be guessed. As a result, the health monitoring system 500 is simple and easy to use because, for example, the user can determine signs of illness, positive / negative, etc. by simply performing normal urination while staying at home or at work. Good health monitoring service with good sustainability.

Also, the health monitoring system 500 is not limited to application to homes and workplaces, but can be used for patient health management in nursing homes and hospitals, and can reduce risk on the management side. Here, “urination information” refers to various types of information related to urination of the user, and may include urine volume, urine temperature, urine components, and the like.

For example, the health monitoring system 500 may be configured by the measurement device 200 alone or the measurement device 200 and the user terminal 300. . In addition, in this example, an example of a service using a cloud service is shown. However, a cloud doctor service using artificial intelligence (for example, by machine learning using deep learning or the like) (for example, a patient's health status over a network) It can also be used for a physical condition medical service) and a cloud mother service (for example, a service for monitoring a child's health and physical condition over a network).

<Configuration>
Hereinafter, the configuration of the server 100, the measurement apparatus 200, and the user terminal 300 will be described. FIG. 2 is a block diagram illustrating an example of functional configurations of the server 100, the measurement apparatus 200, and the user terminal 300. In addition, in arrangement | positioning of each part, you may change suitably between the server 100, the measuring apparatus 200, and the user terminal 300 according to the operating environment, the condition, etc. of each apparatus. For example, the analysis unit 121, the correction unit 122, the analysis unit 123, and the estimation unit 124 of the server 100 may be arranged in the control unit 230 of the measurement apparatus 200 or may be arranged in the control unit 320 of the user terminal 300. As illustrated in FIG. 2, the server 100 includes a communication unit 110, a control unit 120, and a storage unit 130.

Further, the server 100 can be configured in a multi-stage configuration. For example, the server 100 may be configured by a server (relay server) installed in a facility and a server that includes a specific area including a plurality of facilities or all areas. . As the transmission timing of the relay server, (1) a threshold value is set for the storage capacity of the storage unit 250 (2) periodically (for example, every fixed time determined in consideration of the capacity of the storage unit 130). The timing when the threshold is reached may be used as the transmission timing.

The communication unit 110 includes a reception unit 111 and a transmission unit 112, and has a function of executing communication with the measurement apparatus 200 and the user terminal 300 via the network 400. The communication may be either wired or wireless, and any communication protocol may be used as long as mutual communication can be performed.

The receiving unit 111 has a function of receiving measurement data and the like from each measuring device 200 and each user terminal 300 via the network 400 according to the control of the control unit 120 and transmitting the measurement data to the control unit 120. Specifically, the receiver 111 stores the water temperature information of the water in the bowl of the toilet bowl from the measuring device 200 and the water containing the urine of the user of the toilet bowl (hereinafter referred to as “urine-containing water”). Voltage information based on the potential difference between the electrodes by immersing the electrode in urine-containing water, user identification information for identifying the user, illuminance information, and imaging information obtained by imaging the film reacted with the reagent in the imaging unit 212 (hereinafter referred to as “imaging information”) Is transmitted to the control unit 120.

The transmission unit 112 has a function of transmitting control data and the like to each measuring device 200 and monitoring result data and the like to each user terminal 300 through the network 400 according to the control of the control unit 120. Specifically, for example, the transmission unit 112 includes user information (for example, ID information) stored in the storage unit 130 for control of the user identification unit 220, measurement and photographing of the measurement unit 210, and user identification unit 220. Dynamic parameter data and the like necessary for identification are transmitted to the measuring apparatus 200, and display data representing monitoring results such as analysis results related to the analyzed urine component, estimation results related to the positive and negative of the estimated disease, etc. It transmits to the user terminal 300.

The control unit 120 is a processor that includes an analysis unit 121, a correction unit 122, an analysis unit 123, and an estimation unit 124, and has a function of controlling each unit of the server 100. Further, when the analysis result is transmitted from the analysis unit 123 or when the estimation result is transmitted from the estimation unit 124, the control unit 120 displays the text, a table, or a graph on the display unit 330 of the user terminal 300. Generate display data. The control unit 120 transmits the generated display data to the transmission unit 112 for transmission to the user terminal 300.

The analysis unit 121 has a function of analyzing urination by analyzing a fluid model obtained by modeling a region where the fluid flows based on the fluid information. Here, “fluid information” refers to information necessary for fluid analysis, and is composed of toilet bowl shape information (hereinafter referred to as “shape information”), information on the amount of water stored in the toilet bowl, water temperature information, and the like. Is done.

Specifically, the analysis unit 121 flows around the measurement unit 210 based on at least one of, for example, the shape information of the toilet bowl, the amount of water stored in the toilet bowl, or the water temperature information. Based on the fluid model obtained by modeling the fluid, urination is analyzed by analyzing the fluid around the measurement unit 210 and calculating the amount of urine. In addition to the toilet bowl shape information, the amount of stored water in the toilet bowl, and the water temperature information, the analysis unit 121 includes at least information on the toilet environment such as the amount information of the detergent or the component information of the detergent. By adding any one of them, the urination information may be analyzed by modeling the fluid based on these. This eliminates the need to collect urine alone to measure urine volume, or to measure urine volume from the rate of change in water level using a measuring instrument attached to a toilet bowl or drainage pipe. A health monitoring system can be provided.

Modeling of the fluid is based on the water temperature information generated from the measured water temperature of the stored water and urine-containing water using, for example, regression analysis by SVM (Support vector machine), etc. It is possible to construct and analyze a prediction model of how it will change and eventually converge. In the regression analysis, the SVM may be combined with the data structure derived by the kernel method for analysis. As another example, a regression model may be constructed and analyzed using regression analysis by the MCMC method (Markov Chain Monte Carlo) (Markov chain Monte Carlo method). In addition to these, as an example of modeling a fluid region by using fluid simulation, it is conceivable to use a finite element method or a CFD (Computational Fluid Dynamics) method.

As an example, when the analysis unit 121 uses regression analysis in the modeling of the fluid, the urine volume q _u is the amount of change T of the temperature of the stored water in the toilet bowl before urination and the temperature of the urine-containing water after urination. by using the _a, and the temperature difference T _b between the temperature of urination containing water after urination and (constant between core temperature 36-38) temperature of the urine, and a parameter q _w of each shape of the toilet bowl, the formula ( It can be expressed by a mathematical model as in 1).

The correction unit 122 has a function of correcting the voltage information based on the water amount information and the urination information including the urine amount. Specifically, for example, the correction unit 122 calculates the dilution level by dividing the urine volume by the sum of the water volume and the urine volume, and corrects the voltage information based on the dilution level. As a result, it is possible to acquire voltage information in consideration of dilution by stored water in the bowl of the toilet bowl, and to analyze urine components.

As an example, the correction unit 122 uses the urine volume q _u , the water volume q _t in the bowl of the toilet bowl, and the potential difference E as the voltage information as the voltage information E ′ corrected as the voltage information based on the dilution degree, It can be expressed as (2).

The correction unit 122 has a function of correcting shooting information based on illuminance information. Here, “illuminance information” refers to information representing the illuminance (brightness) (lx) of the film surface of the photographing unit 212. Specifically, for example, the correction unit 122 performs correction by adjusting the brightness of the RGB value to an appropriate value based on the illuminance information. As a result, RGB values can be obtained in consideration of the influence of illumination, and color measurement can be performed with high accuracy.

The analysis unit 123 has a function of analyzing urine components based on voltage information or corrected voltage information (hereinafter referred to as “voltage information (after correction)”). Specifically, the analysis unit 123 analyzes the molecular concentration of components such as chloride, glucose, potassium, sodium, and urea in urine based on, for example, voltage information (after correction). Further, the ph value can be analyzed as shown in FIG. Thereby, even if urine is diluted with stored water, it can be analyzed with high accuracy. Further, the analysis unit 123 transmits the analysis result to the control unit 120 in order to generate display data to be displayed on the user terminal 300.

The analysis unit 123 also has a function of analyzing the urine component based on the imaging information or the corrected imaging information (hereinafter referred to as “imaging information (after correction)”). Specifically, for example, the analysis unit 123 measures the color of a color development reaction of a specific component in urine with respect to the reagent based on imaging information (RGB values), and the specific component in urine corresponding to the color or its concentration Analyze. Further, the analysis unit 123 transmits the analysis result to the control unit 120 in order to generate display data to be displayed on the user terminal 300. Thereby, analysis of specific components in urine and their concentrations by bioassay (such as immunochromatography) can be realized automatically and simply without human intervention, such as by visual inspection.

The estimation unit 124 has a function of estimating a user's disease based on the analyzed urination information of urination. Specifically, the estimation unit 124 estimates the user's disease based on, for example, the analyzed specific component in urine (specifically, for example, the concentration of the component). As an example, as shown in FIG. 10, the urine sugar value is calculated by analyzing the concentration of glucose in urine, and it is estimated whether diabetes is positive or negative. FIG. 10 also shows the correspondence between the measurement result of the other measurement unit 210 or the analysis result of the analysis unit 123 (referred to as “measurement / analysis result”) and information such as a disease estimated from the measurement / analysis result. An example is shown. In the estimation by the estimation unit 124, the estimation described in the example of the association may be included. In addition, the estimation unit 124 transmits the estimation result to the control unit 120 in order to generate display data to be displayed on the user terminal 300.

In the estimation by the estimation unit 124, (1) estimation based on a threshold value and (2) estimation based on machine learning can be used. For example, in the estimation of (1), the estimation unit 124 compares the measurement result with a threshold value stored in the storage unit 130, for example, normal (or negative) if the value is within the threshold value, and exceeds the threshold value. If so, it is judged as abnormal (or positive) and the disease is estimated. In the estimation of (2), the feature quantity of the measurement result is extracted, and a feature vector is created based on the feature quantity. The created feature vectors are data created using multiple sets of dictionary data (measurement values and test results linked to the measurement values (results of positive or negative disease based on analysis results and estimation results)). The data is used on the basis of training data (teacher data) in machine learning, and a disease is estimated based on the identification result. As the machine learning technique, a neutral network (perceptron), SVM, or the like may be used. Thereby, the estimation accuracy of the estimation unit 124 can be improved by the learning effect of machine learning.

The storage unit 130 has a function of storing various programs, data, and parameters necessary for the operation of the server 100. Specifically, for example, the storage unit 130 includes fluid information (toilet bowl shape information, toilet water volume information), imaging information, weight information, illuminance information, user identification information, and communication unit 110, control unit. 120 and parameters necessary for the operation of the storage unit 130 are stored. For example, as shown in FIG. 8, the storage unit 130 stores information necessary for analysis and analysis, measurement results, and inspection results (analysis results and estimation results) in various databases (hereinafter referred to as “DB”). Remember. The data storage and management method is not limited to the DB, and may be stored and stored in various setting files (hereinafter referred to as “setting file”) such as a definition file, a parameter file, and a temporary file. The storage unit 250 is typically realized by various recording media such as an HDD (Hard Disc Drive), an SSD (Solid State Drive), and a flash memory (SD (Secure Digital) memory card). Various DBs are shown in <Data> described later.
The above is the configuration of the server 100.

Next, the configuration of the measuring apparatus 200 will be described.
As shown in FIG. 2, the measurement apparatus 200 includes a measurement unit 210, a user identification unit 220, a control unit 230, a communication unit 240, and a storage unit 250. Moreover, the measuring apparatus 200 can arrange | position each part to several apparatus. For example, as shown in FIG. 4, the measurement unit 210 is arranged in a device as shown on the right side of FIG. 4, while the user identification unit 220, the control unit 230, the communication unit 240, and the storage unit 250 are placed on the left side of FIG. They can be placed together on separate devices as shown. Thus, a device in which only the measuring unit 210 is arranged is installed in the bowl of the toilet bowl, etc., and one device may be installed as long as there is no problem in communication, and the device configuration has versatility with respect to the shape of the toilet bowl. It can be.

The measuring unit 210 includes an electrode unit 211, a photographing unit 212, an illuminance sensor unit 213, and a temperature measuring unit 214. For example, as shown in FIG. 3, the measurement unit 210 may be installed such that at least a part of the electrode unit 211, the imaging unit 212, and the temperature measurement unit 214 is immersed in water stored in the bowl of the toilet bowl. When the measurement unit 210 is notified from the user that the measurement start is input by an input unit provided in the control unit 230, the transmission is triggered by the electrode unit 211, the imaging unit 212, the illuminance sensor unit 213, and the temperature measurement. Each measurement can be started by the unit 214.

The measurement unit 210 has at least one of temperature information generated by the temperature measurement unit 214 (for example, the water temperature of stored water or urine-containing water) or voltage information generated by the electrode unit 211 (for example, potential difference) at a predetermined threshold. When it reaches, each measurement of each unit constituting the measurement unit 210 can be automatically started or ended. As a result, the user can start the measurement in the normal urination action without performing the selection operation action of starting or ending each time the measurement is started or finished, and a user-friendly measuring device can be provided. In addition, it is preferable to set it as 38 degree | times as a threshold value of the temperature information of a measurement start.

In addition, the measurement unit 210 may automatically start the measurement triggered by the user identification unit 220 completing the user identification process. Furthermore, the measurement unit 210 may provide a threshold value for each measurement item, and may end the measurement with the trigger of the acquisition of data that reaches the threshold value. Further, the measurement unit 210 may manually start or end the measurement by an operation input from the display unit 330 of the user terminal 300. Furthermore, a human sensor (not shown) is provided in the measuring apparatus 200, and the measurement is started by detecting that a human sign is detected by infrared rays or the like of the human sensor, or that the human sign is lost. The measurement may be terminated with the detection as a trigger.

The electrode unit 211 measures the electromotive force (potential difference, voltage value) by the electrolyte and the current value flowing between the electrodes immersed in urine-containing water using two or more electrodes for a specific component in the urine that is an electrolyte. And has a function of generating voltage information. Specifically, for example, the electrode unit 211 includes two or more electrodes, a potentiometer, and an ammeter in order to measure the concentration of a specific component in urine. For example, the electrode unit 211 uses one electrode as a reference electrode and another electrode as a working electrode, so that these electrodes are immersed in urine-containing water, and the concentration (activity of urine components for analysis of urine-containing water) ) To measure the electromotive force difference between the working electrode and the reference electrode in response to the potentiometer. Voltage information is generated based on the measurement result, and the generated voltage information is transmitted to the transmission unit 242 via the control unit 230 in order to transmit the voltage information to the server 100.

Here, “voltage information” refers to information relating to electromotive force (potential difference, voltage value) due to a specific component (electrolyte) in urine generated using the electrode of the electrode unit 211. In addition, although the example using the ion selective electrode method was shown, the enzyme electrode method (GOD (Glucose OxiDase) method) may be used, and the electrode method using three electrodes is added by adding an electrode as a counter electrode. It may be used. Thereby, the density | concentration etc. of the specific component in urine can be measured based on the produced | generated voltage information.

As an example, the potential difference E as voltage information, the pH value pH _i of the reference electrode, and the pH value pH _o which is a hydrogen ion concentration as a characteristic component in urine can be expressed as the following equation (3). Usually, pH _i ≈7, α designates sensitivity, and e designates asymmetric potential. For example, in an ideal electrode with a water temperature of 25 ° C., α = 1 and e = 0.

The photographing unit 212 has a function of photographing a reaction state by causing a color component to react with a specific component in urine using a bioassay. Specifically, for example, the photographing unit 212 includes a film that changes color according to a component of urine-containing water and a photographing unit that photographs the film. Here, the “film” can be added with a reagent to cause a color reaction of a specific component in urine, and is in the form of a tape (for example, a thin band-like thickness that can be wound on a reel, etc. ), Any material may be used, and it may be composed of a polymer component such as a synthetic resin, or may be composed of a fiber such as paper or cloth. Note that the film is preferably transparent. For example, when the imaging unit 212 uses an immunochromatography method as an assay method, the film includes a sample pad, a conjugate pad, a test line (detection line), a control line, a membrane, an absorption pad, and the like. This is not the case. The structure of the film will be described later with reference to FIGS.

The urine-containing water is immersed in the sample pad and absorbed, and the RGB (Red Green Blue) value of the color developed by the color reaction of the test line and control line is read by taking a picture with a photographing means such as a camera. RGB values) are transmitted to the transmission unit 242 via the control unit 230 for transmission to the server 100.

Note that the server 100 measures the color developed by the color reaction based on the photographing information. Accordingly, it is possible to measure the color at a lower cost than reading the wavelength using a spectroscope or the like. At this time, it is assumed that noise is included, but the correction unit 122 of the server 100 can remove the noise.

Here, the prior arts of Patent Documents 1 and 2 use an antigen-antibody reaction such as an immunochromatographic assay method, add a specimen to a pad to cause an antigen-antibody reaction, and form a complex.

FIG. 3 is a diagram schematically illustrating an example of an overview of the health monitoring system 500. This example is an example in which the measurement apparatus 200 is installed in a Western-style toilet and a health monitoring system is used. The type of toilet bowl is not limited to a western style toilet bowl, and a Japanese style toilet bowl or the like may be used for any type of toilet bowl as long as the toilet bowl has water for washing and drainage. As shown in FIG. 3, a part (for example, the measurement unit 210) that measures information related to the stored water and urine-containing water of the measuring device 200 is installed in a device immersed in the stored water in the bowl of the toilet bowl. Other parts (for example, the user identification unit 220, the control unit 230, and the communication unit 240) that do not need to be immersed in the device may be arranged in another device, and for example, the device may be installed to be installed in the tank. In addition, the device in which the user identification unit 220 is arranged is located at a position where the user terminal 300 or the like is placed so that the device can read the QR code information output from the user terminal 300 owned by the user and the information output from the IC card. It is preferable that the device be arranged. Thereby, it is possible to perform measurement after identifying the user without inputting user identification information to the measuring apparatus 200 every time the user uses it.

Next, the internal structure of the measuring unit 210 constituting the measuring apparatus 200 will be described below.
<Embodiment 1>
FIG. 5 is a diagram schematically illustrating an example of the internal structure of the measurement unit 210 according to the first embodiment. Specifically, FIG. 5 shows an example of the structure relating to the film of the photographing unit 212 constituting the measuring unit 210. As shown in FIG. 5, the photographing unit 212 includes two reels that stretch a film from one reel and wind it around the other reel, and automatically rotate the reel at every measurement start or every measurement end. In this way, the film can be sequentially sent out and stored in the stored water in which urine flows.

Specifically, as the film of the photographing unit 212, as an example of a roll type, a reel 10a on which an unused film 30a is wound and a reel 20a on which a used film 30a is wound are arranged in a measuring unit 210. Then, the film 30a is stretched from the reel 20b and wound around the reel 20a, so that the film 30a is sequentially sent and immersed in the stored water or urine-containing water. The photographing unit 212 causes a color reaction of the reagent placed on the immersed film, and photographs the reaction by photographing means (not shown) of the photographing unit 212. In addition to the roll type example shown in FIG. 5, as an example of the strip type, the film is taken out one by one and immersed in water or urine-containing water sequentially, and the reagent placed on the film is subjected to a color reaction. You may let them. Thus, the user does not need to change the film every measurement and can save time and effort, so that the measuring device 200 that is easy to use can be provided.

<Embodiment 2>
FIG. 6 is a diagram schematically illustrating an example of the internal structure of the measurement unit 210 according to the second embodiment. As shown in FIG. 6, the measuring unit 210 is divided into two layers, an upper part and a lower part, with the partition 40b as a reference, and the upper part (the side where the reel 20b on which the used film is wound) is disposed from the partition 40b. As a use part, the lower part (arrangement side of the reel 10b on which an unused film is wound) from the partition 40b can be used. The discard unit may be used as a storage space for discarding the used water-soluble film by dissolving it in the stored water in the toilet bowl.

Specifically, for example, when a used film is flushed (when water in the toilet is pushed into the measuring unit 210 when the toilet is flushed with urine or the like), a part of the water is used. May be disposed of in the disposal unit and washed by each flushing. In addition, since the waste section stores the used film, it is necessary to create an environment in which bacteria do not easily propagate. Therefore, for example, the discarding unit may contain a chemical such as a surfactant, or may be sterilized or antibacterial, or may be evacuated to prevent breeding. The configuration of the film 30b, the reel 20a, and the reel 10b may be a roll type as shown in the first embodiment, or the partition 40b is automatically opened when all the films on the reel 10b are used up. Move to the upper disposal section, store it, and then place a reel (not shown) on which unused film held in the measuring device is wound on the reel 10b of the used section to renew the film. It may be an automatic cartridge type. Thereby, when using the measurement part 210 for a long period of time, it can continue using it, maintaining a sanitary condition easily.

Next, the structure of the film constituting the photographing unit 212 and the reagent placed on the film will be described below. FIG. 7 is a diagram schematically illustrating an example of the configuration of the film and the reagent that constitute the imaging unit 212. As shown in FIG. 7, using a top film 60 for protecting the surface of the reagent and a support film 80 for placing the reagent (to make a support for the reagent), the top film 60 and the support film 80 Thus, a film constituting the photographing unit 212 can be formed with a reagent interposed therebetween. It is conceivable that the top film 60 (1) dissolves the top film 60 at the time of measurement using a water-soluble film, and (2) incorporates a mechanism for peeling the top film 60 into the measurement unit 210 and peels it immediately before the measurement. By (1) or (2), it is possible to protect the reagent until immediately before the measurement and prevent the reagent from being deteriorated. Further, without using the top film 60, (3) the amount of air touched immediately before the measurement is reduced as much as possible by storing the reel around which the unused film of the measuring unit 210 is wound in a highly confidential space. Thus, it is possible to prevent the deterioration of the reagent.

<Data>
Here, in the present embodiment, as an example, an example of the data configuration of various DBs stored in the storage unit 130 will be described with reference to FIG. The various DBs are not limited to the storage unit 130 of the server 100 as a storage destination, and may be the storage unit 250 of the measurement device 200 or the storage unit 330 of the user terminal 300. Further, it goes without saying that the data configuration may be changed as appropriate according to the functional configuration of the server 100, processing contents, and the like.

For example, as an example, a toilet model number, water amount (water level, mass, volume, etc.), water temperature (water temperature information of the stored water), and washed It includes information such as presence / absence, installation location (latitude / longitude information, address, building name, etc.), use start time (toilet use start time), and the like. In addition, the toilet information DB may be configured to include information (not shown) regarding the toilet environment, such as amount information of the detergent or the like, or component information of the detergent or the like. The toilet information DB holds a record for each toilet. Information associated with the toilet model number (for example, toilet bowl shape information, toilet water volume information, etc.) may be stored in the DB, or may be stored in the DB without using a network system such as the Internet. You may search and acquire.

Next, the threshold value DB is a DB that stores a threshold value that is a criterion for determining whether the measurement result is positive or negative, normal or abnormal. For example, as an example, the threshold value (absolute) for each measurement item and measurement item (absolute) Reference information as an absolute index for each measurement item), threshold values for each measurement item (for each user) (reference values as a personalized index for each user for each measurement item), and the like.

Next, the measurement / inspection result DB is a DB that stores measurement results and inspection results for each user. For example, as an example, a user ID (user identification information), measurement items, measurement values, inspection items, inspection results ( (Analysis result, estimation result), measurement date and time (year / month / day, hour / minute / second), and inspection date / time (year / month / day, hour / minute / second) are included.

Next, the dictionary data DB is a DB that stores dictionary data, and includes, for example, information such as measurement values, inspection results (analysis results, estimation results), and the like. The dictionary data DB identifies feature vectors created from measured values as so-called teacher data in machine learning. The dictionary data stored in the dictionary data DB may be defined and stored in a setting file. If the setting file is used, it is considered that the dictionary data reading and updating processing speed is improved as compared to using the DB.

Next, the user DB is a DB that stores information for uniquely identifying a user. For example, as an example, a user ID (alphanumeric information uniquely assigned), a user's name, gender, height, It includes information such as body weight, mass information measured by the measuring device 200, toilet ID of one or more toilets associated with the user.
The data structure of various DBs has been described above.

Next, an example of a data configuration for associating the measurement / analysis result of the health monitoring system 500 with information such as disease will be described with reference to FIG. FIG. 10 is a data conceptual diagram showing the association. For example, as an example, the albumin component in urination is used as input information, and the color development of the film reacted with the reagent or the like is measured by the input information using the immunochromatography method using the immunochromatography method. The albumin concentration is analyzed, and it is determined whether or not the corresponding threshold value is exceeded for the analysis result. Based on the determination result, the user estimates whether diabetes is positive or negative.

The user identification unit 220 identifies the user using the IC card, the user terminal 300, etc. (step S12). In addition, after the said step, the measurement part 212 may once measure the water temperature of a stored water (not shown). The illuminance sensor unit 213 measures the illuminance on the film surface (step S13). The measurement unit 210 starts each measurement when it is transmitted from the user that the measurement start is input manually by the input means provided in the control unit 230 (step S14). Note that this step can be omitted when the electrode unit 211, the imaging unit 212, and the temperature measurement unit 214 automatically start measurement.

When the measurement starts automatically or manually when the temperature to be measured reaches a certain threshold, the temperature measurement unit 214 measures the temperature of the stored water or urine-containing water and generates water temperature information (step S15). . When the measurement starts automatically or manually when the measured potential difference reaches a certain threshold, the electrode unit 211 measures the potential difference between the electrodes and generates voltage information (step S16). When the measurement is started automatically or manually, the photographing unit 212 sends out the film so that the sample pad portion of the film is immersed in the urine-containing water, and photographs the RGB luminance signals of the test line and the control line by photographing means such as a camera. (Step S17).

The temperature measuring unit 214 automatically ends the measurement when the temperature to be measured reaches a certain threshold value, and the electrode unit 211 automatically terminates the measurement when the potential difference to be measured reaches a certain threshold value. (Step S18).

The analysis unit 121 analyzes (calculates) the urine volume by analyzing the sputum fluid using the fluid model obtained by modeling the fluid flowing around the measurement unit 210 based on the shape information, the water amount information, the water temperature information, and the like. (Step S19). When the measured value is the analysis by the electrode method (the electrode method in step S20), the correction unit 122 calculates the dilution degree based on the analyzed urine volume information and the water volume information, and the voltage information based on the dilution degree. Is corrected (step S21). The analysis unit 123 analyzes the urine component based on the voltage information (after correction) (step S22).

When the measured value is the analysis by the immunochromatography method (the immunochromatography method of step S20), the correction unit 122 calculates the dilution level based on the analyzed urine volume information and the water volume information, and the imaging is performed based on the dilution level. The information is corrected (step S23). In this step, the correction unit 122 may correct the shooting information based on the illuminance information in addition to the dilution level. The analysis unit 123 analyzes the urine component based on the imaging information (after correction) (step S24). The analysis unit 123 creates a feature vector based on the analysis result, and identifies the created feature vector based on training data (dictionary data) (step S25). The estimation unit 124 estimates a user's disease based on the analyzed urination information (for example, analyzed urine component) (step S26).

<Embodiment 3>
In the above description, it is described that the user identifying unit 220 may identify and analyze the user. Here, details of the configuration will be described. In the above embodiment, an example of user identification by a plurality of methods is shown, but in this embodiment, the user identification unit 220 performs wireless communication with the user terminal 300 to perform user identification. To do. By the way, one toilet may be provided in one private room so as to be installed in each house, or a plurality of toilets may be provided adjacent to each other as shown in FIG. In the example of the sketch of the toilet illustrated in FIG. 13, an example in which the toilet 1300a, the toilet 1300b, and the toilet 1300c are provided in adjacent private rooms is illustrated. Each

toilet

220a, 220b, 220c transmits a beacon signal is delivered to the user terminal 300 of the user who has entered the other toilet, and the response signal from the user terminal 300 of the user who has entered the next private room May be received.

More specifically, as shown in FIG. 14, it is assumed that the reach range of the beacon signal transmitted from the user identification unit 220a is within the range indicated by the dotted line 1302a. Similarly, the reach range of the beacon signal transmitted from the user identifying unit 220b is within the range indicated by the dotted line 1302b, and the reach range of the beacon signal transmitted from the user identifying unit 220c is within the range indicated by the dotted line 1302c. Suppose that At this time, for example, it is assumed that a certain user A enters a private room in which the toilet 1300a is installed. In this case, the user terminal 300a of the user A may receive not only the beacon signal from the user identification unit 220a but also the beacon signal from the user identification unit 220b and return a response signal. By the way, it is assumed that the user B enters the private room where the toilet 1300b is installed while the user A is in the private room where the toilet 1300a is installed. Then, the user terminal 300b of the user B may receive not only the beacon signal from the user identification unit 220b but also the beacon signal from the user identification unit 220a. Then, the user terminal 300b transmits a response signal to the user identification unit 220a and the user identification unit 220b. Therefore, the user identification part 220a may recognize that the user A and the user B are the users who are using the toilet 1300a. Similarly, the user identification unit 220b may be recognized by the user A and the user B as users who are using the toilet 1300b.

Therefore, in the third embodiment, a system configuration in which such a possibility is reduced and erroneous recognition of which user the measured result corresponds to will be described.

FIG. 14 is a block diagram illustrating a configuration example of the health monitoring system according to the third embodiment. Hereinafter, only the configuration according to the present embodiment will be described, and aspects other than the aspects shown here will not be described as conforming to the contents shown in the above embodiments. In the block diagram illustrated in FIG. 14 and the block diagram illustrated in FIG. 2, the user identification unit 220 includes a sensor unit 222. Along with this, the operation of the control unit 230 also differs. Here, the user identification unit 220 includes the sensor unit 222. However, this may be provided in a place other than the user identification unit 220, and the information sensed by the sensor unit 222 is the user identification unit. What is necessary is just to be able to implement | achieve the structure transmitted to 220. FIG.

As an example, the health monitoring system according to the third embodiment is held by a detection unit (sensor unit 222) that detects that a user has entered a predetermined range from the toilet and a user that exists within the predetermined range from the toilet. An acquisition unit (user identification unit 221) for periodically acquiring user information for identifying a user by performing wireless communication with a communication device, and a specifying unit (user) for identifying the user based on the user information An identification unit 221), a measurement unit (electrode unit 211) for measuring the urine of the toilet user or the accumulated water into which urination flows, and analyzing the urine component of the user based on the potential measured by the measurement unit An analysis unit (121) that generates urination information and an estimation unit (124) that estimates a user's disease based on the urination information.

In the health monitoring system, the specifying unit (user identification unit 220) specifies the user based on the action of the user. Hereinafter, the main configuration according to the third embodiment will be described, and contents that overlap the above-described contents (such as potential measurement and disease estimation) will be omitted.

The sensor unit 222 is a sensor having a function of acquiring various types of information in the toilet, and may be composed of one or a plurality of sensors. The sensor unit 222 can be realized by, for example, an ultrasonic sensor, an infrared sensor, a temperature sensor, an optical sensor, or the like. For example, the distance between the ultrasonic sensor and the door can be measured by emitting an ultrasonic wave in the direction of the toilet door using an ultrasonic ray sensor and calculating the time until the reflected wave is detected. it can. Therefore, by storing the distance when the door is closed, it is possible to detect that the door has been opened and closed when the distance detected by the ultrasonic sensor is different from the stored distance. it can. In addition, by using an infrared sensor, it is possible to detect the entry and exit of the user into the toilet. In addition, by using an optical sensor, for example, a change in brightness in the toilet can be detected to detect entry and exit of the user. Therefore, the sensor unit 222 can detect whether or not the user is using the toilet in each toilet. The sensor unit 222 can set a detectable detection range, and may be set appropriately according to the shape of the private room of the toilet. Further, the sensor unit 222 may include a contact sensor that is provided in the door opening / closing unit and can detect opening / closing of the door, or may include a pressure sensor provided in the toilet seat of the toilet. The detection of the opening and closing of the door can detect the user's entry and exit, and the pressure sensor can detect the user's seating on and off the toilet seat. Moreover, it is good also as providing the multiple sensors of the same kind and improving the reliability of the sensing data.

The user identification unit 220 has a function of transmitting a beacon signal through the transmission unit 242 as appropriate (for example, every second). The beacon signal is a signal in a predetermined format, and is a signal for requesting user information from the user terminal 300. The user information here is information that can uniquely identify the user holding the user terminal 300, and indicates the above-described user ID.

The user identification unit 220 transmits a beacon signal via the transmission unit 242 as appropriate (for example, every second). The beacon signal is a radio signal that can reach a predetermined distance from the user identification 220. In the example of the user identification unit 220a shown in FIG. 13, the reachable range from the user identification unit 220a is inside the dotted line 1302a. When the user identification unit 220 transmits a beacon signal and a response signal transmitted from the user terminal 300 in response thereto is transmitted from the reception unit 241, based on the user information included in the response signal, Identify the user using the toilet.

In addition, when a plurality of users are detected, the user identification unit 220 identifies the user by specifying the user's behavior based on the sensing data from the sensor unit 222. For example, when the sensor unit 222 is detecting a user and is recognizing two pieces of user information, if the sensor unit 222 is detecting a user when the user information cannot be recognized, the recognition is performed. The user indicated by the user information of the person who can do can be specified as the user who is currently using the toilet. When a user uses a toilet, he / she approaches the private room of the toilet, opens the toilet door, enters the toilet, closes the toilet door, prepares the toilet seat, adds use, cleans up the toilet door If the teacher data of the sensing data in each state is held from the sensor unit 222 in each situation, the teacher data is compared with the actual sensing data. By doing so, it is possible to specify the user's behavior. And the user identification part 220 specifies the user who is using the corresponding toilet from the judgment of those user's actions, and the reception status of the response signal from the user terminal 300.

Next, a configuration necessary for the user terminal 300 in the third embodiment will be described.

The reception unit 311 of the communication unit 310 has a function of receiving a beacon signal from the user identification unit 220. The receiving unit 311 transmits the received beacon signal to the control unit 320.

When receiving the beacon from the user identification unit 220, the control unit 320 has a function of extracting user information stored in the storage unit 340 of the user terminal 300 and generating a response signal including the extracted user information. The control unit 320 has a function of causing the transmission unit 312 to return the generated response signal to the user identification unit 220 (the device that transmitted the beacon signal).

The above is the description of the configuration of the measurement apparatus 200 and the configuration of the user terminal 300 according to the third embodiment.

<Operation>
From here, the health monitoring process including the user identification process accompanying the user's action by the user identification unit 220 will be described. FIG. 15 is a flowchart showing the operation.

As illustrated in FIG. 15, the reception unit 241 of the measurement apparatus 200 receives the response signal transmitted from the user terminal 300 in response to the beacon signal transmitted from the transmission unit 242 (step S1501). The response signal includes a user ID that uniquely identifies the user holding the user terminal 300. The receiving unit 241 transmits the received response signal to the user identifying unit 221.

The user identifying unit 220 uses the corresponding toilet based on the user ID included in the transmitted response signal and the user behavior that can be detected based on the sensing data sequentially transmitted from the sensor unit 222. Is identified (step S1502). Further details of this process will be described later.

The user identifying unit 220 identifies the user who is using the toilet, and the measuring unit 210 analyzes the stored water. That is, first, the measurement unit 210 measures stored water (step S1503).

The measuring unit 210 measures liquid information from the measurement result of the stored water (step S1504). The measured liquid information is transmitted from the transmission unit 242 together with the specified user information, and is received by the reception unit 111. The receiving unit 111 transmits the received liquid information to the control unit 120.

The control unit 120 estimates a user's disease based on the measured liquid information (step S1505).

The details of the user's disease estimation method in steps S1503 to S1505 are as described above.

And the control part 120 transmits the information regarding the estimated disease to the user terminal 300 of the user shown by the user information received with the liquid information from the transmission unit 112, the information regarding the estimated disease (step S1506). Thereby, the information regarding the disease is received by the receiving unit 311 of the user terminal 300 and displayed on the display unit 330. Therefore, the user can recognize from his / her urination a disease that he / she may have.

After transmitting information on the estimated disease, the server 100 stores the information in the storage unit 130 in association with the user ID of the corresponding user. The storage may also be performed in the storage unit 340. Thereby, the information regarding the disease estimated with respect to the user can be memorize | stored and it can use for a user's medical examination.

Now, the details of the user specific process will be described. FIG. 16 is a flowchart illustrating an example of processing related to user identification by the user identification unit 220.

As illustrated in FIG. 16, the user identification unit 220 is periodically (for example, every second) addressed to a device (user terminal 300) existing within a predetermined range from the own device, and the user holding the device. A beacon signal for requesting information is transmitted from the transmission unit 242 (step S1601). It is assumed that the beacon signal is periodically transmitted even during the subsequent processing, and the transmission of the beacon signal is omitted in the following.

The receiving unit 241 determines whether or not a response signal to the beacon signal transmitted periodically is received (step S1602). If no response signal has been received (NO in step S1602), the process returns to step S1601. When the response signal is received (YES in step S1602), the user identification unit 220 extracts a user information included in the response signal, thereby identifying a user who may use the toilet.
Next, based on the sensing data from the sensor unit 222, the user identification unit 220 determines whether or not the user has entered the private room where the corresponding toilet is installed and is using it (step S1603). .

When only one response signal is received from the user terminal 300 and it is detected that the user is using the toilet based on the sensing data from the sensor unit 220 (YES in step S1603) The measuring apparatus 200 measures the accumulated water including the user's urination and acquires the liquid information. Then, the liquid information is transmitted from the transmission unit 242 to the server 100, whereby the server 100 executes a process of estimating the user's disease (step S1604).

Then, the disease information estimated from the server 100 is transmitted to the user terminal 300 via the transmission unit 112 (step S1605). Thereby, in the user terminal 300, the information of the estimated disease is displayed, and the user can recognize the possibility of his own disease.

On the other hand, when it can be determined that the user is not using the corresponding toilet based on the sensing data from the sensor unit 220 while receiving the response signal (NO in step S1603), the measurement device 200 receives the signal. The unit 241 determines whether or not it has received a response signal for the beacon signal that is periodically transmitted (step S1606). When the response signal is not received (YES in step S1606), the user indicated by the response signal determines that the corresponding toilet is not used, and the process of step S1601 is performed without performing the disease estimation process. Return to.

In a state where the response signal is continuously received, the receiving unit 241 determines whether or not a new response signal has been received (step S1607). The new response signal here refers to a response signal including a user ID different from the user ID included in the already received response signal. If a new response signal has not been received (NO in step S1607), the process returns to step S1606. If a new response signal has been received (YES in step S1607), the user identification unit 220 determines whether the user is using the toilet based on the sensing data from the sensor unit 222 ( Step S1608).

If it is determined that the user is not using the toilet based on the sensing data from the sensor unit 222 (NO in step S1608), the process returns to step S1606.

As described above, the user identifying unit 220 according to the third embodiment is configured so that the user who uses the toilet is not confused when the user who uses the toilet is specified. The user can be identified based on the behavior information. Therefore, when the user is confirmed by radio, response signals from a plurality of users are received, and upon recognition, the measurement information (information on disease estimation) is erroneously detected for the user terminal of the wrong user. Can be greatly reduced.

In addition, in this Embodiment 3, although the user identification part 220 is supposed to transmit a beacon signal regularly, this is not the limitation. For example, transmission of a beacon signal is started at the timing when the sensor 222 of the user identification unit 220 detects the user. And it is good also as a structure which stops transmission of a beacon signal at the timing when the sensor part 222 stops detecting a user. According to the configuration, although the user identification may be slightly delayed from the configuration shown in the third embodiment, it is possible to realize power saving of the user identification unit 220 as compared with the configuration shown in the third embodiment.

In Embodiment 3 described above, the user identification unit 220 does not disclose a configuration for communicating with other user identification units 220, but the user identification unit 220 can communicate with other user identification units 220. It may be configured. And the user identification part 220 may transmit the information to another user identification part, when user information is received. At this time, the sensing data that can be detected by the sensor unit 222 may also be transmitted to another user identification unit. Thereby, the specific accuracy of the user can be further improved by using the information identified by the other user identifying unit.

For example, the user identification unit 220a receives a response signal from the user terminal 300a and cannot identify the user based on the sensing data from the sensor unit 220a, and the user identification unit 220b It is assumed that the response signal from 300a is received and the user can be identified based on the sensing data from the sensor unit 220b. At this time, the user identification unit 220a receives information indicating that the response signal from the user terminal 300a is received from the user identification unit 220b and that the user can be identified, and thereby the user identification unit 220a The accuracy with which it can be estimated that the user holding the user terminal 300a is not using the toilet corresponding to 220a can be improved.
