<Structure>
Hereinafter, the configurations of the server 100, the measuring device 200, and the user terminal 300 will be described. FIG. 2 is a block diagram showing an example of the functional configurations of the server 100, the measuring device 200, and the user terminal 300. The arrangement of each part may be appropriately changed between the server 100, the measuring device 200, and the user terminal 300 according to the operating environment and the situation of each device. For example, the analysis unit 121, the correction unit 122, the analysis unit 123, and the guessing unit 124 of the server 100 may be arranged in the control unit 230 of the measuring device 200, or may be arranged in the control unit 320 of the user terminal 300. As shown 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, and may be composed of, for example, a server (relay server) installed in the facility and a specific area including a plurality of facilities or a server including all the areas. .. The timing at which the relay server transmits predetermined information is as follows: (1) periodically (for example, at regular intervals determined in consideration of the capacity of the storage unit 130, etc.), and (2) the storage capacity of the storage unit 250. It is also possible to set a threshold value in and set the timing to transmit when the threshold value is reached. The timing of transmission may be any timing and is not limited to these examples.

The communication unit 110 includes a reception unit 111 and a transmission unit 112, and has a function of executing communication with the measuring device 200 and the user terminal 300 via the network 400. The communication may be 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 or the like from each measuring device 200 and each user terminal 300 and transmitting the measured data to the control unit 120 under the control of the control unit 120 via the network 400. Specifically, the receiving unit 111 receives water temperature information from the measuring device 200 to the pooled water in the bowl of the toilet bowl and the water containing the urination of the user of the toilet bowl (hereinafter referred to as "urination-containing water"). Voltage information due to the potential difference between the electrodes by immersing the electrodes in water containing urination, user identification information for identifying the user, illuminance information, and photographing information of the film on which the reagent reacts in the photographing unit 212 (hereinafter, "photographing information"). ) Is received and 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 under the control of the control unit 120 via the network 400. Specifically, for example, the transmission unit 112 includes user information (for example, ID information) stored in the storage unit 130 for controlling the user identification unit 220, measurement and photographing of the measurement unit 210, and the user identification unit 220. The dynamic parameter data and the like necessary for the identification of the above are transmitted to the measuring device 200, and the display data showing the monitoring result such as the analysis result related to the analyzed urine component and the estimated result related to the positive and negative of the estimated disease is displayed. It is transmitted to the user terminal 300.

The control unit 120 is a processor including an analysis unit 121, a correction unit 122, an analysis unit 123, and a guessing 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 and the guess result is transmitted from the estimation unit 124, the control unit 120 displays the estimation result on the display unit 330 of the user terminal 300 as a text, a table or a graph. Generate display data for. The control unit 120 transmits the generated display data to the transmission unit 112 in order to transmit it to the user terminal 300.

The analysis unit 121 has a function of analyzing urination by analyzing a fluid model that models a region in which a fluid flows based on fluid information. Here, "fluid information" refers to information necessary for fluid analysis, and is composed of information on the shape of the bowl of the toilet bowl (hereinafter referred to as "shape information"), information on the amount of accumulated water in the bowl of the toilet bowl, water temperature information, and the like. Will be done.

Specifically, the analysis unit 121 flows around the measurement unit 210 based on at least one of, for example, shape information of the bowl of the toilet bowl, water amount information of the accumulated water in the bowl of the toilet bowl, water temperature information, and the like. Urination is analyzed by analyzing the fluid around the measuring unit 210 and calculating the urine volume based on the fluid model that models the fluid. In addition to the shape information of the bowl of the toilet bowl, the amount of accumulated water in the bowl of the toilet bowl, and the water temperature information, the analysis unit 121 at least information on the toilet environment such as the amount information of detergent or the like or the component information of detergent or the like. Any one may be added, and the urination information may be analyzed by modeling the fluid or the like based on these. As a result, it is not necessary to collect only urine and measure the urine volume, or to measure the urine volume from the water level change rate with a measuring device attached to the bowl of the toilet bowl or the drain pipe, which is convenient for the user. A health monitoring system can be provided.

In modeling the fluid, for example, the water temperature of the pooled water and the urination-containing water is determined based on the water temperature information generated from the measured water temperature of the pooled water and the urination-containing water using regression analysis by SVM (Support vector machine) or the like. It is conceivable to build and analyze a predictive model of how it changes and finally converges. Further, in the regression analysis, SVM may be analyzed by combining a data structure derived by the kernel method. In addition, as another example, it is conceivable to construct and analyze a regression model using regression analysis by the MCMC method (Markov Chain Monte Carlo). Furthermore, in addition to these, it is conceivable to use the finite element method or the CFD (Computational Fluid Dynamics) method as an example of modeling the fluid region by using the fluid simulation.

As an example, the analyzer 121, when using a regression analysis in the modeling of the fluid, urine volume q _u is the amount of change in temperature of urination containing water after urination and temperature of reservoir water in the toilet bowl before voiding T _{Using a , the temperature difference T b} between the temperature of urine (a constant between core body temperature 36 and 38) and the temperature of water containing urine after urination, _{and the parameter q w} for each shape of the toilet bowl, the following equation ( It can be represented by a mathematical model as in 1).

The correction unit 122 has a function of correcting voltage information based on water amount information and urination information including urine amount. Specifically, for example, the correction unit 122 calculates the degree of dilution by dividing the amount of urine by the amount of water and the sum of the amount of urine, and corrects the voltage information from the degree of dilution. This makes it possible to acquire voltage information in consideration of dilution due to accumulated water in the bowl of the toilet bowl, and to analyze the urine component.

As an example, the correction unit 122 uses the potential difference E'as voltage information corrected by the degree of dilution, the urine volume q _{u , the water volume q t} in the bowl of the toilet bowl, and the potential difference E as voltage information, and uses the following equation. It can be expressed as (2).

The correction unit 122 has a function of correcting shooting information based on illuminance information. Here, the "illuminance information" refers to information representing the illuminance (brightness) (lux) of the film surface of the photographing unit 212. Specifically, for example, the correction unit 122 corrects by adjusting the brightness of the RGB value to an appropriate value based on the illuminance information. As a result, it is possible to obtain an RGB value in consideration of the influence of lighting, and it is possible to perform color measurement with high accuracy.

Further, the correction unit 122 may correct the measurement result (for example, voltage information) by using the information regarding the accumulated water of the toilet bowl. Here, the information regarding the accumulated water of the toilet bowl is the information regarding the accumulated water before the urination of the user of the toilet bowl flows in. For example, the information about the pooled water of the toilet bowl is the pH value of the pooled water before the urination of the user of the toilet bowl flows in. The information on the accumulated water in the toilet bowl is not limited to the pH value, and may be any information as long as it is the information on the accumulated water before the urination of the user of the toilet bowl flows in.

Further, the information regarding the pooled water of the toilet bowl may be the information regarding the pooled water before the urination of the user of the toilet bowl flows in, which has been notified in advance. Information about the pool of water in the toilet bowl is notified in advance by, for example, another user who uses the health monitoring system of the present invention. Further, the information regarding the pooled water of the toilet bowl may be notified in advance by, for example, the provider who provides the pooled water of the toilet bowl. Any provider of water for toilet bowls can be, for example, a water company or public institution that provides tap water, or a predetermined company or public institution that provides water for toilets. good. For example, a water supply company that provides tap water provides information on tap water at a predetermined cycle (for example, on a daily basis), and the information on the tap water is used as information on the accumulated water before urine flows in. Use. In addition, the measuring device 200 of another user who uses the health monitoring system may notify the information about the accumulated water before the urination flows in at a predetermined cycle (for example, every 12 hours).

Further, the correction unit 122 may correct the voltage information based on the elapsed time since the measuring device 200 was installed in the toilet bowl. The measurement accuracy of the electrode unit 211, the photographing unit 212, the illuminance sensor unit 213, and the temperature measuring unit 214 included in the measuring unit 210 of the measuring device 200 may deteriorate with the passage of time. For example, the electrode unit 211 measures the potential difference between two electrodes immersed in the pooled water into which urine has flowed, but the accuracy of the measured potential difference deteriorates with the passage of time. Therefore, the correction unit 122 corrects the potential difference measured by the electrode unit 211 based on the elapsed time since the electrode unit 211 was installed on the toilet bowl.

The correction amount when the correction unit 122 corrects based on the elapsed time may be set in advance. The correction unit 122 corrects the measurement result (for example, voltage information) based on the elapsed time from when the measurement unit 210 is set on the toilet bowl, based on the correction amount set in advance. For example, the correction unit 122 corrects the potential difference measured by the electrode unit 211 based on the elapsed time from the installation of the electrode unit 211.

For example, the correction unit 122 creates a correction model for correcting the measurement result (for example, voltage information) based on the area where the measurement unit 210 is installed, the shape information of the bowl of the toilet bowl in which the measurement unit 210 is installed, and the like. The correction model created by the correction unit 122 is not necessarily limited to the area and shape information, and may be created based on various information such as the frequency of use of the toilet bowl and the usage environment. Further, the correction unit 122 may create a correction model based on the past history of the deterioration over time of the measurement unit 210. For example, the correction unit 122 calculates the average value of the deterioration over time of the plurality of measurement units 210 based on the past history of the deterioration over time of the plurality of measurement units 210, and creates a correction model based on the average value. You may. Then, the correction unit 122 corrects the measurement result measured by the measurement unit 210 based on the created correction model.

Here, the deterioration over time of the measuring unit 210 is different from each other depending on, for example, the frequency of use of the toilet bowl, the usage environment, the device difference between the devices of the measuring device 200, and the like even when they are used in the same area. There is. For example, the deterioration of the measuring unit 210 of one measuring device 200 with time may be slower (or faster) than the deterioration of the measuring unit 210 of the other measuring device 200 with time. Therefore, if the measurement results are corrected for a plurality of measuring devices 200 using the same correction model, the measurement results may be excessively corrected, or the correction amount for the correction of the measurement results may be reduced. There is.

Further, the correction unit 122 may correct the correction amount in the correction based on the elapsed time based on the information regarding the accumulated water of the toilet bowl. The correction unit 122 may correct the correction amount in the correction based on the elapsed time based on the information regarding the accumulated water of the toilet bowl, and correct the voltage information based on the corrected correction amount. For example, the correction unit 122 may correct the correction model based on the information regarding the accumulated water of the toilet bowl. The correction unit 122 may correct the voltage information based on the correction model after the correction.

FIG. 3 is a table showing an outline of correction of the measurement result by the correction unit 122. Note that FIG. 3 is an example in which the correction unit 122 corrects the measurement result measured based on the potential difference measured by the electrode unit 211, and more specifically, the pH value of the accumulated water into which urine has flowed is measured. This is an example of correction.

Each pH value shown in the column of "correction model" in the table shown in FIG. 3 is an example of the pH value when the correction unit 122 corrects the measurement result. As shown in FIG. 3, the correction unit 122 corrects the pH value measured based on the potential difference measured by the electrode unit 211 with a predetermined correction amount three years after the installation, and corrects the corrected pH. The value is output. In the example of FIG. 3, the correction unit 122 as the measurement value of after 3 years from the installation, pH value before urination flows is 8.2 [pH], pH value after flowing voiding 8.5 [ pH ] is output. The values shown in FIG. 3 are merely examples, and may be any value.

On the other hand, the deterioration of the electrode unit 211 over time differs among the plurality of electrode units 211 depending on the usage environment, frequency of use, etc., and when corrected based on the "correction model", the measurement result is excessively corrected. Or, the correction amount of the correction of the measurement result may be reduced.

Therefore, the measurement unit 210 is used to measure the accumulated water before the urination of the user of the toilet bowl flows in, and the measurement result by the measurement unit 210 and the urination of the user of the toilet bowl notified in advance before the urination of the user of the toilet bowl flows in. Compare with information about pool water. Then, the correction amount by the correction model is corrected based on the comparison result.

In the example of FIG. 3, the pH value measured by using the electrode portion 211 three years after the installation is 8.2 [ pH ] with respect to the accumulated water before the urination of the user of the toilet bowl flows in. On the other hand, the pH value of the pooled water before the urination of the user of the toilet bowl notified in advance flows in is 8.0 [ pH ]. That is, if the correction amount due to aging deterioration is corrected using the "correction model", the measurement result will be excessively corrected by 0.2 [pH]. Therefore, in the "correction model", the correction amount after 3 years is corrected by "-0.2 [ pH ]", and the measurement result is output based on the correction amount after the correction. That is, in the example of FIG. 3, it is necessary to correct the pH value after urination flows in by "-0.2 [ pH ]", and the pH value after urination flows in is 8.3 [ pH ]. Will be output.

As described above, the measuring unit 210 corrects the correction amount based on the deterioration over time based on the information regarding the accumulated water before the urination of the user of the toilet bowl is notified in advance, so that the measuring unit 210 has a more accurate measured value. Can be output.

The correction unit 122 does not correct the correction model, but corrects the measurement result corrected based on the correction model again based on the information on the accumulated water before the urination of the toilet bowl user flows in. May be good. For example, the correction unit 122 may correct the correction result of the voltage information corrected based on the elapsed time again based on the information on the accumulated water before the urination of the user of the toilet bowl flows in.

The analysis unit 123 has a function of analyzing the urine component based on the voltage information or the 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 (corrected). The pH value can also be analyzed as shown in FIG. As a result, even if urination is diluted with accumulated water, it can be analyzed accurately. Further, the analysis unit 123 transmits the analysis result to the control unit 120 in order to generate display data for displaying the analysis result on the user terminal 300.

The analysis unit 123 also has a function of analyzing the urine component based on the photographed information or the corrected photographed information (hereinafter, referred to as “photographed information (after correction)”). Specifically, for example, the analysis unit 123 measures the color of the color development reaction of a specific component in urine with respect to the reagent based on the imaging information (RGB value), and the specific component in urine corresponding to the color or its concentration. To analyze. Further, the analysis unit 123 transmits the analysis result to the control unit 120 in order to generate display data for displaying the analysis result on the user terminal 300. This makes it possible to automatically and easily analyze a specific component in urine and its concentration by a bioassay (such as an immunochromatography method) without human intervention, instead of visual inspection by humans.

The guessing unit 124 has a function of guessing the user's disease based on the analyzed urination information of urination. Specifically, the guessing 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. 11, the urinary glucose level is calculated by analyzing the concentration of glucose in urine, and it is estimated whether diabetes is positive or negative. In addition, the guessing unit 124 may guess the distortion of the lifestyle based on the analyzed urination information of urination. The guessing unit 124 may guess, for example, the bias of eating habits and the ups and downs (undulations) of stress as lifestyle-related distortions. The distortion of lifestyle is not limited to these examples, and may be any kind. Further, FIG. 11 shows the measurement results of the other measurement units 210 or the analysis unit 123 (referred to as “measurement / analysis results”), and information such as diseases and lifestyle-related distortions estimated from the measurement / analysis results. An example of associating with is shown. In the estimation of the estimation unit 124, the estimation described in the example of the association may be included. Further, the estimation unit 124 transmits the estimation result to the control unit 120 in order to generate display data for displaying the estimation result on the user terminal 300.

In the estimation by the estimation unit 124, (1) estimation by threshold value and (2) estimation by machine learning can be used. As an example, in the estimation of (1), the guessing unit 124 is normal (or negative) if it is within the threshold value, and exceeds the threshold value by comparing the measurement result and the threshold value stored in the storage unit 130. If so, it is judged to be abnormal (or positive) and the disease is inferred. In the estimation of (2), the feature amount of the measurement result is extracted, and the feature vector is created based on the feature amount. The created feature vector is data created by using a set of dictionary data (measured value and test result (result of positive or negative of disease based on analysis result and estimation result) associated with the measured value) in multiple cases. , Data used as training data (teacher data) in machine learning) is used as a reference, and the disease is inferred from the identification result. As the machine learning technique, a neutral network (perceptron), SVM, or the like may be used. As a result, 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 required for the server 100 to operate. Specifically, for example, the storage unit 130 contains fluid information (shape information of the bowl of the toilet bowl, information on the amount of accumulated water in the toilet bowl), photographing information, weight information, illuminance information, user identification information, communication unit 110, and control unit. The parameters necessary for the operation of the 120 and the storage unit 130 are stored. As an example, the storage unit 130 stores information necessary for analysis, analysis, and the like, measurement results, and inspection results (analysis results, estimation results) in various databases (hereinafter referred to as "DB"). And remember. The data storage and management method is not limited to the DB, and may be saved and stored in various setting files (hereinafter referred to as "setting files") 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 device 200 will be described.
As shown in FIG. 2, the measuring device 200 includes a measuring unit 210, a user identification unit 220, a control unit 230, a communication unit 240, and a storage unit 250. In addition, each part of the measuring device 200 can be arranged in a plurality of devices. For example, as shown in FIG. 5, the measuring unit 210 is arranged in the device as shown on the right side of FIG. 5, while the user identification unit 220, the control unit 230, the communication unit 240, and the storage unit 250 are located on the left side of FIG. It can be placed together in another device as shown. As a result, a device in which only the measuring unit 210 is arranged may be installed in a bowl of the toilet bowl or the like, and one device may be appropriately installed within a range where communication is not a problem. 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. As shown in FIG. 4, the measuring unit 210 may be installed so that at least a part of the electrode unit 211, the photographing unit 212, and the temperature measuring unit 214 is immersed in the pooled water in the bowl of the toilet bowl. When the user transmits that the measurement start has been input by the input means provided in the control unit 230, the measuring unit 210 uses the transmission as a trigger to trigger the electrode unit 211, the photographing unit 212, the illuminance sensor unit 213, and the temperature measurement. Each measurement can be started by the unit 214.

In the measuring unit 210, at least one of the temperature information generated by the temperature measuring unit 214 (for example, the water temperature of the accumulated water or the urine-containing water) or the voltage information generated by the electrode unit 211 (for example, the potential difference) is set to a predetermined threshold value. When it reaches the limit, each measurement of each unit constituting the measurement unit 210 can be automatically started or stopped. As a result, the user can start the measurement in the normal urination action without performing the start or end selection operation each time the measurement starts or ends, and can provide a convenient measuring device. The threshold value of the temperature information at the start of measurement is preferably 38 degrees.

Further, the measurement unit 210 may automatically start the measurement when the user identification unit 220 completes the user identification process. Further, the measurement unit 210 may set a threshold value for each measurement item and end the measurement triggered by the acquisition of data reaching the threshold value. Further, the measurement unit 210 may manually start or end the measurement by inputting an operation from the display unit 330 of the user terminal 300. Further, a motion sensor (not shown) is provided in the measuring device 200, and the measurement is started by detecting the sign of a person by infrared rays or the like of the motion sensor, or the sign of a person disappears. The measurement may be terminated with the detection as a trigger.

The electrode unit 211 uses two or more electrodes to measure the electromotive force (potential difference, voltage value) of the electrolyte and the current value flowing between the electrodes immersed in the urine-containing water for a specific component in urine, which is an electrolyte. It also has the function of generating voltage information. Specifically, for example, the electrode unit 211 is composed of two or more electrodes, a potentiometer, and an ammeter in order to measure the concentration of a specific component in urine. In the electrode unit 211, for example, by using one as a reference electrode and another electrode as an action electrode, these electrodes are immersed in the urine-containing water, and the concentration (activity amount) of the urine component for analysis of the urine-containing water is used. ), The electromotive force difference between the working electrode and the reference electrode is measured with a potential difference meter. 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 generated voltage information to the server 100.

Here, "voltage information" refers to information related to electromotive force (potential difference, voltage value) generated by a specific component (electrolyte) in urine generated by using the electrode of the electrode portion 211. Although an example using the ion-selective electrode method is shown, an enzyme electrode method (GOD (Glucose OxiDase)) may be used, or an electrode method with three poles is used by adding an electrode as a counter electrode. You may. This makes it possible to measure the concentration of a specific component in urine based on the 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 the hydrogen ion concentration as a characteristic component in urine can be expressed by the following equation (3). Normally, pH _i ≈ 7, where α specifies sensitivity and e specifies asymmetric potential. For example, in an ideal electrode having a water temperature of 25 ° C., α = 1 and e = 0.

The imaging unit 212 has a function of causing a color reaction of a specific component in urine with a reagent or the like using a bioassay and photographing the reaction condition. Specifically, for example, the photographing unit 212 is composed of a film that changes color according to the component of urination-containing water and a photographing means for photographing the film. Here, the "film" has a shape in which a reagent can be added to cause a color reaction of a specific component in urine, and a tape-like shape (for example, a strip-like thickness is thin and can be wound up by a reel or the like). ), 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 fibrous material such as paper or cloth. The film is preferably transparent. For example, when the imaging unit 212 uses an immunochromatography method as an assay method, the film is composed of a sample pad, a conjugate pad, a test line (detection line), a control line, a membrane, an absorption pad, and the like. , Not limited to this. The composition of the film will be described later with reference to FIGS. 6, 6 and 7.

The sample pad is soaked with urine-containing water to absorb it, and the RGB (Red Green Blue) value of color development due to the color reaction of the test line and control line is read by taking a picture with a photography means such as a camera, and the picture information (read) is read. The RGB value) is transmitted to the transmission unit 242 via the control unit 230 for transmission to the server 100.

The server 100 measures the color developed by the color reaction based on the shooting information. As a result, the color can be measured at a lower cost than reading the wavelength or the like using a spectroscope or the like. At this time, it is assumed that noise is included, but the noise can be removed by the correction unit 122 of the server 100.

Here, in the prior art of Patent Documents 1 and 2, a sample is added to a pad to cause an antigen-antibody reaction using an antigen-antibody reaction such as an immunochromatography assay to form a complex, and the complex is a different species. There is a problem that it cannot be applied to a test method that further binds to an antibody as a complex and determines positive / negative of pregnancy or disease based on the reaction (for example, color development).

The health monitoring system 500 according to the present invention further includes a film that changes color according to the component of the accumulated water into which urine has flowed, and a photographing unit 212 that includes an imaging means that photographs the film to generate photographing information, and corrects the problem. The unit 122 corrects the imaging information based on the water volume information and the urination information including the urination volume of urination, and the analysis unit 123 analyzes the urine component based on the corrected imaging information. It can also be applied to a test method using an antibody reaction, and more measurements can be made as compared with a conventional urination information measuring device installed in a toilet bowl.

The illuminance sensor unit 213 has a function of measuring the illuminance (brightness) of the film surface photographed by the photographing unit 212. It is composed of a light receiving element such as a photodiode. For example, the illuminance sensor unit 213 converts the light incident on the light receiving element into an electric current to detect the illuminance, and transmits the illuminance information to the server 100, so that the illuminance information is transmitted to the transmission unit 242 via the control unit 230. The server 100 can correct the color measurement result by using the illuminance information. As a result, it is possible to obtain a color measurement result in consideration of the illuminance due to illumination, and it is possible to accurately analyze the reaction condition of a specific component for analysis in urine.

The temperature measuring unit 214 has a function of measuring the temperature of the accumulated water in the bowl of the toilet bowl or the temperature of the urination-containing water and generating water temperature information. The temperature measuring unit 214 includes, for example, a thermistor, an oscillator, and a counter. The thermistor outputs the change in resistance value due to the temperature change, the change in resistance value is converted into a frequency by the oscillator, and the counter measures the frequency to measure the temperature. Since the water temperature information is transmitted to the server 100, it is transmitted to the transmission unit 242 via the control unit 230.

The user identification unit 220 has a function of identifying a target user to be monitored by the health monitoring system 500 using a toilet bowl. As shown in FIG. 4, the user identification unit 220 is connected to the measurement unit 210 by a wire such as a cable, and is provided with a suction means for a pottery device such as a tank so as to be provided in a tank for storing wash water. Alternatively, other mounting means may be provided.

It can be easily identified without any problem.

Further, the user identification unit 220 may be configured to include the measurement unit 221. For example, the measuring unit 221 measures the weight (Kg weight) of the user received by the toilet seat in the case of a Western-style toilet bowl, and stores the measured weight information for each user (hereinafter referred to as "weight information") in the storage unit 250. Remember in. The user identification unit 220 identifies the user based on the weight information and generates the user identification information. In addition, the user identification unit 220 includes a face recognition sensor for face recognition, a posture detection sensor for posture detection, a pulse measuring means for measuring the user's pulse, and a blood pressure measuring means for the user. The user may be identified by measuring the body fat ratio of the user with the blood pressure measuring and the body fat ratio measuring means and measuring the muscle mass of the user with the muscle mass measuring means. Further, the user identification unit 220 may be provided with an infrared sensor to estimate the height of the user and identify the user based on the estimated height. The height of the user is not limited to the infrared sensor, and any sensor may be used as long as the height can be estimated. Further, the user identification unit 220 may include an infrared sensor to measure the operation pattern of the user, identify the user from the measured operation pattern, and generate the user identification information. For example, the user identification unit 220 may determine whether or not the measured operation pattern includes a characteristic operation pattern for each user, and identify the user based on the determination result. It should be noted that the measurement of the user's operation pattern is not limited to the infrared sensor, and any sensor may be used. In addition, the user identification unit 220 identifies the user based on a plurality of measured measurement results (at least two or more such as weight, face, posture, pulse, blood pressure, body fat percentage, muscle mass, height, movement pattern, etc.). You may. Further, the information about the user whose user identifier 220 can be measured is not limited to these examples, and may be any information, and the user identification unit 220 uses the information based on the measured information about the user. It is possible to automatically identify the person.

These user identification information may be transmitted to the server 100 together with the set water temperature information, voltage information, user identification information, illuminance information, and shooting information, or may be transmitted at the identified timing. Since the user identification unit 220 transmits to the server 100, the user identification unit 220 transmits to the transmission unit 242 via the control unit 230. This makes it possible to automatically identify the user as part of normal urination, and the user can easily identify the user each time the toilet bowl is used without having to enter information to identify the user. can.

It receives dynamic parameter data and the like necessary for identifying 220 and transmits them to the control unit 230.

The transmission unit 242 has a function of transmitting measurement data and the like to the server 100 and each user terminal 300 under the control of the control unit 230 via the network 400. Specifically, for example, the transmission unit 242 transmits water temperature information, voltage information, user identification information (including measurement information), illuminance information, and photographing information to the server 100 or each user terminal 300. The transmission timing of the transmission unit 242 is as follows: (1) immediately after the measurement (for example, triggered by the transmission of the measurement data from the measurement unit 210), and (2) periodically (for example, the user's transmission timing). (3) A threshold value may be set for the storage capacity of the storage unit 250 and the transmission timing may be set when the threshold value is reached. ..

The storage unit 250 has a function of storing various programs, data, and parameters required for the measuring device 200 to operate.

FIG. 4 is a diagram schematically showing an example of an overview of the health monitoring system 500. This example is an example in which the measuring device 200 is installed in a Western-style toilet bowl and a health monitoring system is used. The type of toilet bowl is not limited to the Western style toilet bowl, and any type of toilet bowl such as a Japanese style toilet bowl may be used as long as it has a pool of water for washing and drainage. As shown in FIG. 4, a part (for example, the measuring unit 210) for measuring the information related to the accumulated water and the urination-containing water of the measuring device 200 is installed in a device to be immersed in the accumulated water in the bowl of the toilet bowl, and the accumulated water is installed. Other units (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 water may be arranged in another device, for example, the device may be installed so as to be installed in the tank.

It is preferable to use a device that can be arranged. As a result, the user can be identified and measured without inputting the user identification information into the measuring device 200 each time the user uses the measuring device 200.

Next, the internal structure of the measuring unit 210 constituting the measuring device 200 will be described below.
<Embodiment 1>
FIG. 6 is a diagram schematically showing an example of the internal structure of the measuring unit 210 according to the first embodiment. Specifically, FIG. 6 shows an example of the structure related to the film of the photographing unit 212 constituting the measuring unit 210. As shown in FIG. 6, the photographing unit 212 includes two reels in which the film is stretched from one reel and wound on the other reel, and the reels are automatically rotated each time the measurement starts or the measurement ends. As a result, the film can be sequentially sent out to the pooled water into which urine has flowed and immersed.

By stretching the film 30a from the reel 20b and winding it around the reel 20a, the film 30a is sequentially sent out and immersed in the pooled water or the urine-containing water. The photographing unit 212 causes a color reaction of the reagent placed on the immersed film, and the reaction is photographed by the photographing means (not shown) of the photographing unit 212. In addition to the roll type example shown in FIG. 6, as an example of the strip type, the films are taken out one by one, immersed in pooled water or urination-containing water in sequence, and the reagent placed on the film undergoes a color reaction. You may let me. As a result, the user does not have to replace the film each time the measurement is performed, and the trouble of replacement can be saved, so that the easy-to-use measuring device 200 can be provided.

<Embodiment 2>
FIG. 7 is a diagram schematically showing an example of the internal structure of the measuring unit 210 according to the second embodiment. As shown in FIG. 7, the measuring unit 210 is divided into two layers, an upper part and a lower part, based on the partition 40b, and the upper part (the side where the reel 20b on which the used film is wound is arranged) is discarded from the partition 40b. As a result, the lower part from the partition 40b (the arrangement side of the reel 10b on which the unused film is wound) can be used as the used portion. The disposal unit may be used as a storage space for disposal by dissolving the used water-soluble film in the pooled water in the toilet bowl.

Specifically, for example, a used film is partially watered when it is flushed (when the water in the toilet bowl is pushed into the measuring unit 210 when cleaning the toilet bowl where urination or the like is flushed with water). May be disposed of by letting it enter the disposal section and cleaning it with each flush. In addition, since the disposal section stores used films, it is necessary to create an environment in which bacteria do not easily grow. Therefore, specifically, the disposal unit may contain a chemical such as a surfactant, be sterilized or antibacterial, or may be evacuated to prevent reproduction. 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 portion 40b is automatically opened when all the films on the reel 10b are used up. The film is renewed by moving to the upper disposal section for storage, and then arranging a reel (not shown) on which the unused film held in the measuring device is wound on the reel 10b of the used section. It may be an automatic cartridge type. As a result, when the measuring unit 210 is used for a long period of time, it can be easily continued to be used while maintaining a hygienic state.

Next, the configurations of the film constituting the photographing unit 212 and the reagents mounted on the film will be described below. FIG. 8 is a diagram schematically showing an example of the configuration of the film and the reagent constituting the photographing unit 212. As shown in FIG. 8, the top film 60 and the support film 80 are used with the top film 60 for protecting the surface of the reagent and the support film 80 for mounting the reagent (to serve as a support for the reagent). It is possible to form a film constituting the photographing unit 212 by sandwiching the reagent with. It is conceivable that the top film 60 is (1) dissolved in the top film 60 at the time of measurement using a water-soluble film, and (2) a mechanism for peeling the top film 60 is incorporated in the measuring unit 210 and peeled immediately before the measurement. According to (1) or (2), the reagent can be protected until immediately before the measurement, and deterioration of the reagent can be prevented. Further, by storing the reel around which the unused film of the measuring unit 210 is wound is stored in a highly airtight space without using the top film 60, the amount of air touched until just before the measurement is reduced as much as possible. Therefore, deterioration of the reagent can be prevented.

<Data>
Here, in the present embodiment, as an example, an example of the data structure 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 the storage destination, and may be the storage unit 250 of the measuring device 200 or the storage unit 330 of the user terminal 300. Needless to say, the data structure may be appropriately changed depending on the functional structure of the server 100, the processing content, and the like.

First, the toilet information DB is a DB that stores information related to the toilet bowl. For example, for example, the toilet bowl model number, the amount of water (water level, mass, volume, etc. of the pooled water), the water temperature (water temperature information of the pooled water), and the washed water. It is composed of information such as presence / absence, installation location (latitude / longitude information, address, building name, etc.), and start time of use (time to start using the toilet bowl). In addition, the toilet information DB may be configured to include information on the toilet environment (not shown) such as amount information of detergent or the like or component information of detergent or the like. The toilet information DB holds records for each toilet bowl. Information associated with the toilet bowl model number (for example, toilet bowl shape information, toilet water volume information, etc.) may be stored in the DB, or may not be stored in the DB, and a network system such as the Internet may be used each time. You may search and obtain it.

Next, the threshold value DB is a DB that stores a threshold value that serves as a criterion for determining whether the measurement result is positive or negative, normal or abnormal, and the like. It is composed of information such as (reference value as an absolute index for each measurement item), threshold value for each measurement item (for each user) (reference value 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, and inspection results ( It is composed of information such as analysis result, estimation result), measurement date and time (year / month / day, hour / minute / second), and inspection date / time (year / month / day, hour / minute / second).

Next, the dictionary data DB is a DB that stores dictionary data, and is configured to include, for example, information such as measured values and inspection results (analysis results, guessing results), as an example. The dictionary data DB identifies a feature vector created from measured values as so-called teacher data in machine learning. The dictionary data to be saved in the dictionary data DB may be defined and saved in the setting file. It is considered that the reading and updating processing speed of the dictionary data is improved by using the setting file as compared with 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 (uniquely assigned alphanumeric information), a user's name, gender, height, and so on. It is composed of information such as weight, mass information measured by the measuring device 200, and toilet ID of one or more toilets associated with the user.
The above is the data structure of various DBs.

Next, a data configuration example of associating the measurement / analysis results of the health monitoring system 500 with information such as diseases will be described with reference to FIG. FIG. 11 is a data conceptual diagram showing the association. For example, as an example, using the albumin component in urination as input information, the imaging unit 212 measures the color development due to the color reaction of the film that has reacted with the reagent or the like based on the input information using the immunochromatography method, and urine is obtained from the color development. The albumin concentration in the albumin is analyzed, and it is determined whether or not the analysis result exceeds the corresponding threshold. Based on the determination result, the user infers whether diabetes is positive or negative.

<Operation>
FIG. 10 is a flowchart showing an example of processing executed by the health monitoring system 500.
The storage unit 130 stores the shape information of the bowl of the toilet bowl, the water amount information of the stored water, and the water temperature information of the stored water as initial settings in advance or each time of measurement (step S11). The user identification unit 220 identifies the user using an IC card, a user terminal 300, or the like (step S12). After the step, the measuring unit 212 may once measure the water temperature of the accumulated water (not shown). The illuminance sensor unit 213 measures the illuminance on the film surface (step S13).
