[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0016] <Summary> In the following embodiment, a water treatment system 1 for providing a water source will be described.

[0017] Users use water for various purposes in their daily lives. For example, users consume drinking water to replenish their fluids. Other uses of water include cleaning dirt from objects, for example, users use water to wash dishes after meals. Users also use water for showers, baths, laundry, toilets, drink servers, room humidification, and other purposes.

[0018] <Embodiment 1> In the embodiment, a water treatment device 30 capable of providing a water source by having a water treatment function will be described, and a water treatment system 1 realized by installing the water treatment device 30 in various locations will be described.

[0019] FIG. 1 is a diagram showing an overview of a water treatment system 1. The water treatment system 1 is composed of water treatment devices 30 (in the example of FIG. 1, water treatment devices 30A, 30B, and 30C are shown) installed in various locations, and a server (not shown in FIG. 1) capable of communicating with these water treatment devices 30. In the example shown, the water treatment devices 30A and 30C each have a moving mechanism 370. The moving mechanism 370 has, for example, wheels, and enables the water treatment device 30 to travel by driving the wheels, etc. It should be noted that the water treatment device 30B does not have the moving mechanism 370, and does not have the function of self-propelling.

[0020] The water treatment device 30 is installed in various places. For example, the water treatment device 30A is installed on outdoor land 5. By installing the water treatment device 30A on the outdoor land 5, water can be used outdoors for various purposes such as drinking, showering, and toilet use. For example, the water treatment device 30A provides a water purification function, so that water can be purified so that the user can drink it.

[0021] For example, the water treatment device 30B is installed to provide a water treatment function for the building 6. The water treatment device 30B is installed inside or outside the building 6.

[0022] For example, the water treatment device 30C is installed in a mobile body 7 such as an automobile to provide a water treatment function. The water treatment device 30B is mounted inside or outside the mobile body 7. For example, the mobile body 7 may be a camper or the like that is equipped with various facilities that use water, such as a kitchen for cooking, a toilet, etc. The water treatment device 30C provides a water treatment function according to various uses of water used in the mobile body 7.

[0023] 1 shows an example in which the water treatment device 30 is used as a single independent device, but the function of the water treatment device 30 may be incorporated into facilities such as a building to provide the water treatment function. For example, the water treatment device 30 may be incorporated into a washing machine, sink, water purifier, shower room, bathroom, toilet, bathtub, humidifier, dehumidifier, air conditioner, etc. in a building. As will be described later, the water treatment device 30 provides the water treatment function by including a water treatment module 40. The function of water treatment may be provided to a user by incorporating a combination of water treatment modules 30 into facilities such as a building.

[0024] Each water treatment device 30 transmits the water treatment functions it provides and the history of water treatment to the server, which allows the server to accumulate information about the demand for water treatment in the environment in which each water treatment device 30 is installed.

[0025] <Overall system configuration> FIG. 2 is a diagram showing the overall configuration of the water treatment system 1. As shown in FIG.

[0026] 2, the water treatment system 1 includes a terminal device 10 (in the illustrated example, terminal device 10A and terminal device 10B are shown), a server 20, and a water treatment device 30 (in the illustrated example, water treatment device 30A and water treatment device 30B are shown). The terminal device 10, the server 20, and the water treatment device 30 are communicatively connected via a network 80. As illustrated, the water treatment device 30 (water treatment device 30B) may also communicate with the server 20 via the terminal device 10 (terminal device 10B).

[0027] The terminal device 10 is a device operated by each user. The terminal device 10 is realized by a mobile terminal such as a smartphone or tablet compatible with a mobile communication system. In addition, the terminal device 10 may be, for example, a stationary PC (Personal Computer) or a laptop PC. As shown as the terminal device 10B in FIG. 2, the terminal device 10 includes a communication IF (Interface) 12, an input / output IF 13, a memory 15, a storage unit 16, and a processor 19. The server 20 includes a communication IF 22, an input / output IF 23, a memory 25, a storage 26, and a processor 29.

[0028] The terminal device 10 is communicatively connected to the server 20 via a network 80. The terminal device 10 is connected to the network 80 by communicating with communication devices such as a wireless base station 81 compatible with communication standards such as 5G and LTE (Long Term Evolution) and a wireless LAN router 82 compatible with wireless LAN (Local Area Network) standards such as IEEE802.11.

[0029] The communication IF 12 is an interface for inputting and outputting signals so that the terminal device 10 can communicate with an external device.

[0030] The input device 13 is an input device (for example, a touch panel, a touch pad, a pointing device such as a mouse, a keyboard, etc.) for receiving an input operation from a user.

[0031] The output device 14 is an output device (such as a display, a speaker, a vibrator, etc.) for presenting information to a user.

[0032] The memory 15 is for temporarily storing programs and data to be processed by the programs, and is a volatile memory such as a DRAM (Dynamic Random Access Memory).

[0033] The storage unit 16 is a storage device for saving data, such as a flash memory or a hard disk drive (HDD).

[0034] The processor 19 is hardware for executing an instruction set written in a program, and is composed of an arithmetic unit, a register, peripheral circuits, and the like.

[0035] The server 20 acquires and stores as a database the history of water treatment in each water treatment device 30. The server 20 predicts demand for water treatment based on the data stored in the database.

[0036] The communication IF 22 is an interface for inputting and outputting signals so that the server 20 can communicate with external devices.

[0037] The input / output IF 23 functions as an interface with an input device for receiving an input operation from a user and an output device for presenting information to the user.

[0038] The memory 25 is for temporarily storing programs and data to be processed by the programs, and is a volatile memory such as a DRAM (Dynamic Random Access Memory).

[0039] The storage 26 is a storage device for saving data, such as a flash memory or a hard disk drive (HDD).

[0040] The processor 29 is hardware for executing an instruction set written in a program, and is composed of an arithmetic unit, a register, peripheral circuits, and the like.

[0041] Next, each device constituting the water treatment system 1 will be described.

[0042] <Configuration of water treatment device 30> First, the water treatment device 30 constituting the water treatment system 1 will be described.

[0043] Fig. 3 is a block diagram showing the configuration of water treatment device 30. As shown in Fig. 3, water treatment device 30 has a water treatment module installation mechanism 32. Water treatment module installation mechanism 32 has a plurality of installation mechanisms (installation mechanisms 32A, 32B, 33C, ...).

[0044] The multiple installation mechanisms are mechanisms for accepting installation of the water treatment modules 40. In the illustrated example, water treatment modules 40 are shown as water treatment modules 40A and 40B. The water treatment device 30 has a water receiving unit 36 ​​that supplies water to be treated to the water treatment module installation mechanism 32, and a treated water output unit 37 that outputs water treated by each water treatment module 40 installed in the water treatment module installation mechanism 32 to the outside. The water receiving unit 36 ​​accepts water supply from the outside of the water treatment device 30, for example, by a pump or the like. The treated water output unit 37 outputs water treated by the water treatment module 40 to the outside of the water treatment device 30. Note that drainage after the user uses the output water can also be input to the water receiving unit 36.

[0045] Fig. 4 is a diagram showing examples of the external appearance of a plurality of installation mechanisms for accepting installation of a water treatment module 40 in the water treatment device 30. Fig. 4(A) is a diagram showing a front view of an insertion surface 31 for accepting installation of a water treatment module 40 in the water treatment device 30. Fig. 4(B) is a diagram showing the external appearance of the insertion surface 31 as viewed from an oblique direction. Fig. 4(C) is a diagram showing another example for installing a water treatment module 40 in a plurality of installation mechanisms.

[0046] 4(A), water treatment device 30 has a plurality of installation mechanisms (installation mechanisms 32A, 32B, 32C, ...) on insertion surface 31. In the illustrated example, each installation mechanism has an equivalent structure so that water treatment module 40 can be connected. Water treatment module 40 is prepared according to function, and has a size corresponding to the structure of the installation mechanism.

[0047] Each installation mechanism provides the function of the water treatment module 40 to the user by installing a water treatment module 40 having a certain volume. For example, each installation mechanism has a connection part for connecting to the water treatment module 40. The connection part has, for example, a pump mechanism for supplying water to be treated to the water treatment module 40, and a discharge mechanism for discharging treated water treated by the water treatment module 40. The water treatment module 40 has a connection part at an end for connecting to the installation mechanism. This allows the installation mechanism and the water treatment module 40 to be connected at the connection part, and provides the water treatment device 30 with the function of each water treatment module 40.

[0048] 4(B), the water treatment device 30 has a door 33 for covering the insertion surface 31. The water treatment device 30 is about to receive the installation of the water treatment module 40A from the installation mechanism. By inserting the water treatment module 40A into the insertion surface 31, the water treatment module 40 can be installed in the installation mechanism.

[0049] In the illustrated example, the water treatment device 30 has 16 installation mechanisms (installation mechanisms 32A, 32B, ... 32P) so that a water treatment module 40 having a predetermined size can be installed on the insertion surface 31. As shown in Fig. 4(B) , the water treatment module 40 may have an appearance (e.g., the color of the water treatment module 40) that is identifiable by the user depending on the function and performance.

[0050] In the example of Figure 4(B), the size of the water treatment module 40 is equal to a specified unit, but depending on the water treatment function required of the water treatment module 40, it may be necessary to make the water treatment module 40 larger than the specified unit.

[0051] Fig. 4(C) allows a water treatment module 40 larger than that in the example of Fig. 4(B) to be installed in the water treatment device 30. As shown in Fig. 4(C), a water treatment module 40B is shown that is twice as large as the insertion surface 31 based on the unit. Also, a water treatment system 40C that is four times as large as the insertion surface 31 based on the unit may also be installed in the water treatment device 30.

[0052] Each water treatment module 40 includes a component having a water treatment function, such as a filter. In addition to the water treatment function, each water treatment module 40 also includes a component that supplies energy for operating the water treatment device 30, such as a power supply function. As described above, the water treatment device 30 is equipped with each water treatment module 40, thereby providing the user of the water treatment device 30 with the functions of the water treatment modules 40.

[0053] As described above, the water treatment device 30 has a configuration in which the water treatment module 40 can be installed, and therefore can also be regarded as a pod in which the water treatment module 40 can be housed.

[0054] Returning to FIG. 3, the description of the configuration of the water treatment device 30 will continue.

[0055] The water treatment device 30 has a configuration for communicating with an external device and a configuration for performing data processing. The water treatment device 30 includes a plurality of antennas (antenna 311, antenna 312), wireless communication units (first wireless communication unit 321, second wireless communication unit 322) corresponding to the respective antennas, an operation reception unit 330 (including a touch-sensitive device 331 and a display 332), a voice processing unit 340, a microphone 341, a speaker 342, a position information sensor 350, a camera 360, a movement mechanism 370, a storage unit 380, and a control unit 390.

[0056] The water treatment device 30 also has functions and configurations (e.g., a circuit for connecting to a power source to receive power, a battery for storing power, a power supply circuit for controlling the supply of power from the battery to each circuit, etc.) that are not specifically shown in Fig. 3. As shown in Fig. 3, each block included in the water treatment device 30 is electrically connected by a bus or the like.

[0057] The water treatment device 30 does not need to have all the components shown in FIG. 3, and may have only some of the components. For example, the water treatment device 30 may not have some of the components of the terminal device 10 capable of communicating with the water treatment device 30. For example, the water treatment device 30 may not have components for notifying the user, such as the voice processing unit 340, the microphone 341, the speaker 342, etc. Furthermore, the water treatment device 30 may not have components capable of sensing in the terminal device 10, such as the position information sensor 350 and the camera 360. Furthermore, there may be cases where the water treatment device 30 does not need to have an antenna and a wireless communication unit according to multiple communication standards, such as only needing to support either a mobile communication system or short-distance wireless communication.

[0058] Antenna 311 radiates the signal generated by water treatment device 30 as a radio wave. Antenna 311 also receives the radio wave from space and provides the received signal to first wireless communication unit 321.

[0059] Antenna 312 radiates the signal generated by water treatment device 30 as a radio wave. Antenna 312 also receives the radio wave from space and provides the received signal to second wireless communication unit 322.

[0060] The first wireless communication unit 321 performs modulation and demodulation processing and the like for transmitting and receiving signals via antenna 311 so that the water treatment device 30 can communicate with other wireless devices. The second wireless communication unit 322 performs modulation and demodulation processing and the like for transmitting and receiving signals via antenna 312 so that the water treatment device 30 can communicate with other wireless devices. The first wireless communication unit 321 and the second wireless communication unit 322 are communication modules including a tuner, a Received Signal Strength Indicator (RSSI) calculation circuit, a Cyclic Redundancy Check (CRC) calculation circuit, a high-frequency circuit, and the like. The first wireless communication unit 321 and the second wireless communication unit 322 perform modulation and demodulation and frequency conversion of wireless signals transmitted and received by the water treatment device 30, and provide the received signals to the control unit 390.

[0061] The operation reception unit 330 has a mechanism for receiving an input operation by a user. Specifically, the operation reception unit 330 is configured as a touch screen and includes a touch-sensitive device 331 and a display 332. The touch-sensitive device 331 receives an input operation by a user of the water treatment device 30. The touch-sensitive device 331 detects a touch position of the user on the touch panel, for example, by using a capacitive touch panel. The touch-sensitive device 331 outputs a signal indicating the touch position of the user detected by the touch panel to the control unit 390 as an input operation. Note that the operation reception unit 330 may receive an input operation by a mechanism that physically deforms, such as a button.

[0062] The display 332 displays data such as images, videos, and text under the control of the control unit 390. The display 332 is realized by, for example, an LCD (Liquid Crystal Display), an organic EL (Electro-Luminescence) display, electronic paper, or the like.

[0063] The audio processing unit 340 modulates and demodulates an audio signal. The audio processing unit 340 modulates a signal provided from the microphone 341 and provides the modulated signal to the control unit 390. The audio processing unit 340 also provides the audio signal to the speaker 342. The audio processing unit 340 is realized, for example, by a processor for audio processing. The microphone 341 accepts audio input and provides an audio signal corresponding to the audio input to the audio processing unit 340. The speaker 342 converts the audio signal provided from the audio processing unit 340 into audio and outputs the audio to the outside of the water treatment device 30.

[0064] The position information sensor 350 is a sensor that detects the position of the water treatment device 30, and is, for example, a GPS (Global Positioning System) module. The GPS module is a receiving device used in a satellite positioning system. In the satellite positioning system, signals are received from at least three or four satellites, and the current position of the water treatment device 30 in which the GPS module is mounted is detected based on the received signals. The position detected by this GPS module can be used, for example, when notifying the server 20 of the position information of the water treatment device 30.

[0065] The camera 360 is a device that receives light with a light receiving element and outputs the received light as a captured image. The camera 360 is, for example, a depth camera that can detect the distance from the camera 360 to a subject being photographed.

[0066] Storage unit 380 is configured with, for example, a flash memory, and stores data and programs used by water treatment device 30. In one aspect, storage unit 380 stores user information 381 and water treatment history information 382.

[0067] User information 381 is information about a user who receives the water treatment function provided by water treatment device 30. The user information includes information for identifying the user, information about the water treatment module 40 used by the user, information about the water treatment module 40 owned by the user, and the like.

[0068] The water treatment history information 382 is information indicating the results of sensing by various sensors equipped in the water treatment device 30. For example, the water treatment history information 382 holds a history of water treatment performed in each water treatment module 40 installed in the water treatment module installation mechanism 32.

[0069] The control unit 390 reads a program stored in the storage unit 380 and executes instructions included in the program to control the operation of the water treatment device 30. The control unit 390 is, for example, an application processor. The control unit 390 operates according to the program to fulfill the functions of an input operation receiving unit 391, a transmission / reception unit 392, a data processing unit 393, and a notification control unit 394.

[0070] The input operation reception unit 391 performs a process of receiving a user's input operation on an input device such as the touch-sensitive device 331. The input operation reception unit 391 determines the type of operation, such as whether the user's operation is a flick operation, a tap operation, or a drag (swipe) operation, based on information on the coordinates where the user touches the touch-sensitive device 331 with a finger or the like. The input operation reception unit 391 also acquires information such as a position designated by the user on the display 332 using a pointing device or the like.

[0071] The transmitting / receiving unit 392 performs processing for the water treatment device 30 to transmit and receive data to and from an external device such as the server 20 in accordance with a communication protocol.

[0072] The data processing unit 393 performs a process of performing calculations on data received as input by the water treatment device 30 according to a program and outputting the calculation results to a memory, etc. For example, the data processing unit 393 performs a process of storing the history of water treatment performed by the water treatment module 40 in the water treatment device 30 in the water treatment history information 382, ​​a process of transmitting the information stored in the water treatment history information 382 to the server 20, etc.

[0073] The notification control unit 394 performs a process of notifying the user of information. The notification control unit 394 performs, for example, a process of displaying a display image on the display 332, a process of outputting sound to the speaker 342, and a process of causing the camera 360 to generate vibrations.

[0074] <Functional configuration of server 20> Next, the configuration of the server 20 will be described.

[0075] 5 is a diagram showing a functional configuration of the server 20. As shown in FIG. 5, the server 20 fulfills the functions of a communication unit 201, a storage unit 202, and a control unit 203.

[0076] The communication unit 201 performs processing for the server 20 to communicate with external devices (for example, the terminal device 10, the water treatment device 30).

[0077] The storage unit 202 stores data and programs used by the server 20. The storage unit 202 stores a water treatment module database 281, a water treatment device database 282, a user information database 283, and external environment information 284.

[0078] The water treatment module database 281 is a database regarding the specifications of the water treatment module 40. Details will be described later.

[0079] The water treatment device database 282 is a database regarding the settings of the water treatment device 30 and the history of the user's use of the water treatment device 30. Details will be described later.

[0080] The user information database 283 is a database for holding information on each user who uses the water treatment device 30. Details will be described later.

[0081] The external environment information 284 is information related to the environment in which the water treatment device 30 is installed. For example, the server 20 acquires parameters that affect the demand for water for the place where the water treatment device 30 is installed and accumulates them in the external environment information 284. For example, the parameters that affect the demand for water include data on the climatic conditions around the place where the water treatment device 30 is installed (weather, temperature, humidity, wind speed, etc.), data on users who use water (inflow and outflow of people, etc.), data on local water sources (river flow rate, groundwater volume, etc.), and time-series data on other information.

[0082] The control unit 203 exerts functions shown as various modules by the processor of the server 20 performing processes according to the programs.

[0083] The operation content acquisition module 2041 acquires the user's operation content when the server 20 accepts information input from a user of the terminal device 10 or the like. For example, when the server 20 presents a screen by the browser of the terminal device 10 to accept the user's operation, the operation content acquisition module 2041 acquires the user's operation content.

[0084] The reception control module 2042 controls the process in which the server 20 receives a signal from an external device in accordance with a communication protocol.

[0085] The transmission control module 2043 controls the process in which the server 20 transmits a signal to an external device in accordance with a communication protocol.

[0086] The water demand prediction module 2044 predicts the demand for water in each area. The water demand prediction module predicts the use of water and the demand for water required at the location where the water treatment device 30 is installed, based on the contents of each database stored in the storage unit 202.

[0087] For example, the water demand prediction module 2044 predicts the use and demand of water in each region based on the track record of water treatment performed by the water treatment device 30 installed in each region, based on the water treatment device database 282. For example, by creating a trained model based on time-series data of the track record of water treatment performed by the water treatment device 30, which is accumulated in the water treatment device database 282, the water demand prediction module 2044 can predict the demand for water based on the trained model.

[0088] For example, the water demand prediction module 2044 may predict the demand for water in each region based on the environmental information of each region shown in the external environment information 284. By creating a trained model based on time-series data of the environmental information of each region and the track record of water treatment performed in the water treatment device 30 installed in each region, the water demand prediction module 2044 can predict the demand for water based on the prediction results of the environmental information of each region and the trained model.

[0089] The combination identification module 2045 identifies a combination of water treatment modules 40 to be installed in the water treatment device 30. The combination identification module 2045 identifies a combination of water treatment modules 40 that is suitable for an application designated by a user. Furthermore, the combination identification module 2045 identifies a combination of water treatment modules 40 that is suitable for the demand, depending on the result of water demand prediction by the water demand prediction module 2044, regardless of the user's designation.

[0090] <Configuration of Terminal Device 10> Next, the configuration of the terminal device 10 will be described.

[0091] Fig. 6 is a block diagram showing the configuration of the terminal device 10. As shown in Fig. 6, the terminal device 10 includes a plurality of antennas (antenna 111, antenna 112), wireless communication units (first wireless communication unit 121, second wireless communication unit 122) corresponding to the respective antennas, an operation reception unit 130 (including a touch-sensitive device 131 and a display 132), a voice processing unit 140, a microphone 141, a speaker 142, a position information sensor 150, a camera 160, a storage unit 180, and a control unit 190.

[0092] Among the configurations of the terminal device 10, the configurations equivalent to those of the water treatment device 30 are similar to the respective configurations of the water treatment device 30, and therefore the description thereof will not be repeated. In other words, the functions of the antennas (111, 112), wireless communication units (first wireless communication unit 121, second wireless communication unit 122), operation reception unit 130, touch-sensitive device 131, display 132, voice processing unit 140, microphone 141, speaker 142, position information sensor 150, and camera 160 of the terminal device 10 will not be described repeatedly, and the functions of the antennas (311, 312), wireless communication units (first wireless communication unit 321, second wireless communication unit 322), operation reception unit 330, touch-sensitive device 331, display 332, voice processing unit 340, microphone 341, speaker 342, position information sensor 350, and camera 360 of the water treatment device 30 will not be described repeatedly. The position information sensor 150 is a sensor that detects the position of the terminal device 10.

[0093] The motion sensor 170 is configured with an acceleration sensor and an angular velocity sensor, and outputs sensing data related to the movement of the terminal device 10. Based on the sensing data, the terminal device 10 detects the inclination of the terminal device 10, whether the terminal device 10 is being shaken, and the like.

[0094] Storage unit 180 is configured with, for example, a flash memory, and stores data and programs used by terminal device 10. In one aspect, storage unit 180 stores user information 181 and water treatment history information 182.

[0095] User information 181 is information about a user who uses water treatment device 30. The user information includes information for identifying the user, information about water treatment module 40 used by the user, information about water treatment module 40 owned by the user, and the like.

[0096] The water treatment history information 182 is information indicating the results of sensing by various sensors equipped in the water treatment device 30. The water treatment history information 182 holds a history of water treatment performed by the water treatment device 30 in each water treatment module 40 installed in the water treatment module installation mechanism 32.

[0097] The control unit 190 reads a program stored in the storage unit 180 and executes instructions included in the program to control the operation of the terminal device 10. The control unit 190 is, for example, an application processor. The control unit 190 operates according to the program to fulfill the functions of an input operation reception unit 191, a transmission / reception unit 192, a data processing unit 193, and a display control unit 194.

[0098] The input operation reception unit 191 performs a process of receiving a user's input operation on an input device such as the touch-sensitive device 131. The input operation reception unit 191 determines the type of operation, such as whether the user's operation is a flick operation, a tap operation, or a drag (swipe) operation, based on information on the coordinates where the user touches the touch-sensitive device 131 with a finger or the like.

[0099] The transmission / reception unit 192 performs processing for the terminal device 10 to transmit and receive data to and from an external device such as the server 20 in accordance with a communication protocol.

[0100] The data processing unit 193 performs a process of performing calculations on the data inputted by the terminal device 10 according to a program and outputting the calculation results to a memory, etc. For example, the data processing unit 193 performs a process of acquiring the results of water treatment performed in the water treatment device 30 (sensing results in the water treatment device 30) from the water treatment device 30 and transmitting the data to the server 20, and a process of presenting a combination of water treatment modules 40 to be installed in the water treatment device 30 to the user of the terminal device 10 on the display 132, etc.

[0101] The notification control unit 194 performs processing for displaying a display image on the display 132, processing for outputting sound to the speaker 142, and processing for causing the camera 160 to generate vibrations.

[0102] <Data Structure> FIG. 7 is a diagram showing the data structures of water treatment module database 281, water treatment device database 282, and user information database 283 stored in server 20. As shown in FIG.

[0103] As shown in FIG. 7, each record in the water treatment module database 281 includes an item "module identification information (ID)", an item "type / function", an item "size", and an item "sensible data".

[0104] The item "module identification information (ID)" is information for identifying each of the multiple types of water treatment modules 40.

[0105] The item “Type / Function” indicates the type into which the water treatment module 40 is classified and the function that the water treatment module 40 performs.

[0106] (i) There are types of water treatment modules 40 that have a function of performing water treatment on the inflowing water. For example, the water treatment modules 40 include those that provide a function of removing substances larger than a certain size using a filter, and those that provide a function of removing microorganisms (bacteria) using optical methods (such as irradiation of ultraviolet rays) or chemical methods.

[0107] (ii) The types of water treatment modules 40 include those that have a function of providing an energy source for operating the water treatment device 30. For example, the water treatment module 40 may be equipped with a solar cell or the like to provide a power supply function for operating the water treatment device 30. In other words, such a water treatment module 40 supplies power to the water treatment device 30, thereby causing the water treatment device 30 to perform its water treatment function.

[0108] (iii) The types of water treatment modules 40 include those that provide water with properties required by the user. For example, the water treatment modules 40 include those that provide a hot water supply function or a cooling function when a user has a demand for hot water or cold water for showering or drinking, and those that provide a function for generating moisture from the air.

[0109] The item "Size" indicates the size occupied by the water treatment module 40 when installed in the water treatment device 30. In this embodiment, as described with reference to FIG. 4 etc., the water treatment device 30 has a plurality of installation mechanisms. As in the example of FIG. 4, each of these installation mechanisms may be regarded as a slot, and the size of each water treatment module 40 may be specified in the item "Size".

[0110] For example, a water treatment module having the item "module identification information (ID)" of "FL01" occupies one of the slots of the water treatment device 30 when installed in the water treatment device 30 (water treatment module 40A in the example of FIG. 4).

[0111] Also, for example, a water treatment module with the item "module identification information (ID)" of "FL02" occupies two slots (water treatment module 40B in the example of FIG. 4).

[0112] The item “Sensible data” indicates what can be sensed by the water treatment module 40 .

[0113] (i) The sensing targets include items that change before and after water treatment. For example, the sensing targets may include items that are sensed to evaluate the performance of purification by water treatment. More specifically, when the water treatment module 40 has a filter or the like to provide the function of obtaining purified water, the sensing targets may be the concentration of a substance or microorganism to be removed in water before treatment with the filter or the like, or the concentration of the substance or microorganism in water after treatment with the filter.

[0114] (ii) The subject of sensing includes items related to the amount of water that has been treated. For example, the amount of water flowing into the water treatment module 40 may be the subject of sensing.

[0115] (iii) The sensing targets include items for evaluating the functions of the water treatment module 40. For example, when the water treatment module 40 provides power, the amount of power generation may be the sensing target. Also, when the water treatment module 40 generates moisture from the air, the amount of water generated may be the sensing target.

[0116] Each record in the water treatment device database 282 includes the items "pod identification information (ID)", "user identification information (ID)", "pod location information", "slot usage status", "designated use", "operation start date", and "sensing data".

[0117] The item “pod identification information (ID)” is information for identifying each water treatment device 30.

[0118] The item “user identification information (ID)” is information for identifying each user who uses the water treatment device 30.

[0119] The item "pod location information" indicates the location where the water treatment device 30 is installed (e.g., information specified by latitude and longitude, or information specified by address). For example, information acquired by the location information sensor 350 of the water treatment device 30 or location information acquired by the user via the terminal device 10 may be set as the location where the water treatment device 30 is installed.

[0120] The item "slot usage status", as shown in FIG. 4, indicates the status of multiple installation mechanisms (multiple slots) possessed by water treatment device 30 being used by water treatment module 40. The item "slot usage status" may include information on the usage status of each of the multiple installation mechanisms (usage status of each slot). The item "slot usage status" may hold, for example, information identifying each of the multiple installation mechanisms, information identifying the type of water treatment module 40 installed in the installation mechanism (module ID), and information on the number of installation mechanisms provided in water treatment device 30. The item "slot usage status" may include information on installation mechanisms that are not being used (empty slots).

[0121] The item "designated use" indicates a use designated by the user in the water treatment device 30 and the usage status of each slot for realizing the use. For example, in the illustrated example, it indicates that, among the multiple installation mechanisms (each slot) of the water treatment device 30, four installation mechanisms (slots "SL01", "SL02", "SL03", and "SL04") are being used to fulfill the function of the use "dishwashing" (i.e., using water to wash after meals).

[0122] The item "operation start date" indicates the timing at which the water treatment function started to be provided by the water treatment device 30. The item "operation start date" may include information on the timing (date, time, etc.) at which the water treatment device 30 started to provide the water treatment function by the combination of the water treatment modules 40 indicated in the item "slot usage status".

[0123] The item "sensing data" indicates the sensing results obtained by each water treatment module 40 installed in the water treatment device 30. In the item "sensing data", information indicating the timing of sensing in each slot and data on the sensing results may be stored in association with each other.

[0124] Each record in the user information database 283 includes an item "user identification information (ID)", an item "pod identification information (ID) being used", an item "modules held", an item "modules in use", and an item "schedule".

[0125] The item “user identification information (ID)” is information for identifying each user who uses the water treatment device 30.

[0126] The item "pod identification information (ID) in use" indicates information (pod ID) for identifying the water treatment device 30 that the user is using.

[0127] The item "Owned module" indicates information (module ID) for identifying modules held by the user among the water treatment modules 40 that can be installed in the water treatment device 30. In other words, it indicates candidates for water treatment modules 40 that the user can install in the water treatment device 30. For example, when the user performs an operation to obtain the water treatment module 40 (such as an operation to purchase the water treatment module 40), the information on the water treatment module 40 held by the user is updated in the server 20.

[0128] The item "module in use" indicates the water treatment module 40 that is being used by the user by installing it in the water treatment device 30. The item "module in use" may be updated by the server 20 acquiring information for identifying the water treatment module 40 installed in the water treatment device 30. For example, the user may operate the terminal device 10 to specify the water treatment module 40 to be installed in the water treatment device 30. In addition, the water treatment device 30 may be able to acquire the identification information held in the water treatment module 40 by installing the water treatment module 40 in the water treatment module installation mechanism 32 in the water treatment device 30.

[0129] The item "schedule" includes information on the user's schedule. For example, the server 20 obtains the information on the user's schedule from a server device that provides a calendar application. The information on the schedule includes, for example, the subject, the location, the date and time, and the content of the schedule.

[0130] For example, the server 20 may predict the demand for water treatment in the water treatment device 30 based on information on a user's schedule. For example, based on information such as the subject and location of the schedule information, it may infer whether there is a demand for water at a certain date and time and the amount of water demand. For example, when information such as "cooking" is included in the subject, schedule contents, etc. of the schedule information, it may infer that there is a demand for water for the purpose of "dishwashing."

[0131] Furthermore, the server 20 can compare information on the user's schedule with actual values ​​of the sensing results (item "sensing data" in the water treatment device database 282) in the water treatment device 30 to create a trained model for outputting prediction results of demand for water treatment based on the schedule information. Based on the trained model and the user's schedule shown in the item "schedule," the server 20 can estimate demand for water treatment around the date and time shown in the schedule.

[0132] <Operation> The operation of each device in the water treatment system 1 will be described below.

[0133] Specifically, (i) a process of accumulating in the server 20 the results of water treatment performed by the water treatment module 40 in the water treatment device 30 will be described. In addition, as a process of presenting to the user a combination of water treatment modules 40 to be installed in the water treatment device 30, (ii) a process of presenting a combination of water treatment modules 40 according to an application designated by the user, (iii) a process of predicting the demand for water treatment at the location where the water treatment device 30 is installed and presenting to the user a combination of water treatment modules 40, and (iv) a process of presenting to the user a combination of water treatment modules 40 according to the water treatment results of the water treatment device 30 will be described. In addition, in a case where the water treatment device 30 can be moved, (v) a process of prompting the user to move the water treatment device 30 according to the demand for water treatment in each area will be described.

[0134] FIG. 8 is a diagram showing a process flow for accumulating in the server 20 the results of water treatment performed by the water treatment module 40 in the water treatment device 30. As shown in FIG.

[0135] In step S801, water treatment device 30 (control unit 390) identifies each of the water treatment modules 40 installed in each slot of water treatment module installation mechanism 32, thereby specifying the combination of water treatment modules 40 installed in water treatment module installation mechanism 32. Water treatment device 30 transmits the specified combination of water treatment modules 40 to server 20.

[0136] In step S853, the server 20 (control unit 203) records information, such as information for identifying the water treatment device 30, information for identifying the user, information indicating the position of the water treatment device 30, the combination of water treatment modules 40 installed in each slot of the water treatment device 30, the use of the water treatment modules 40, and the operation start date when the water treatment device 30 starts performing water treatment with the combination of the water treatment modules 40, in the water treatment device database 282 from the water treatment device 30 or the terminal device 10 of the user of the water treatment device 30. Regarding the use of the water treatment module 40, for example, the user may perform an operation to specify the use of the water treatment device 30 on the terminal device 10 or the water treatment device 30, and the terminal device 10 or the water treatment device 30 may transmit the specified use to the server 20. In addition, the operation start date may be specified by the user, or may be specified by the server 20 based on the timing when the terminal device 10 or the water treatment device 30 transmits the combination of the water treatment modules 40 to the server 20, or the timing when the server 20 receives the combination of the water treatment modules 40.

[0137] In step S805, the water treatment device 30 acquires sensing results regarding the treatment of the water treatment module 40 by the various sensor devices, and transmits the sensing results to the server 20 one by one.

[0138] In step S855, the server 20 receives the sensing result of the water treatment device 30 from the water treatment device 30 or the terminal device 10, and accumulates it in the water treatment device database 282.

[0139] FIG. 9 is a diagram showing a process flow in which the server 20 presents a combination of water treatment modules 40 to the user in accordance with the use of the water treatment device 30 designated by the user.

[0140] In step S931, the terminal device 10 (control unit 190) accepts, from the user, designation of one or more uses for the water treatment device 30. The terminal device 10 transmits the designated uses to the server 20.

[0141] In step S953, the server 20 identifies a necessary water treatment module 40 by referring to the water treatment module database 281 according to the purpose specified by the user for the water treatment device 30. For example, the server 20 identifies a water treatment module 40 according to the purpose by retaining information that associates a purpose that the user can specify with identification information of the water treatment module 40. The server 20 responds to the terminal device 10 with a combination of water treatment modules 40. In addition, the server 20 responds with information on water treatment modules 40 not held by the user, among the combinations of water treatment modules 40 according to the user's purpose, by referring to the user information database 283. In addition, the server 20 responds to the terminal device 10 with the number of slots required for the identified combination of water treatment modules 40.

[0142] In step S935, the terminal device 10 presents the information indicating the combination of water treatment modules 40 received from the server 20 to the user by displaying it on the display 132, for example. When the combination of water treatment modules 40 includes a water treatment module 40 that the user does not own, the terminal device 10 presents it to the user as a water treatment module 40 required for the purpose specified by the user. The terminal device 10 determines the number of slots required for the combination of water treatment modules 40 and the availability of slots for the water treatment modules 40. For example, when the water treatment device 30 does not have the number of available slots required to realize the purpose specified by the user, the terminal device 10 notifies the user of that fact.

[0143] FIG. 10 is a diagram showing a process flow in which the server 20 predicts the demand for water treatment at the location where the water treatment device 30 is installed and presents a combination of water treatment modules 40 to the user.

[0144] In step S1053, the server 20 acquires environmental information (information on local climate conditions, information on local water sources, etc.) at the location where the water treatment device 30 is installed by referring to the external environment information 284. The server 20 predicts the demand for water treatment at the location where the water treatment device 30 is installed based on the environmental information.

[0145] In step S1055, the server 20 identifies candidates for a combination of water treatment modules 40 that meets the prediction result based on the prediction result of the water demand, and transmits the identified candidates to the terminal device 10 of the user.

[0146] In step S1035, the terminal device 10 receives information on the candidates for the combination of water treatment modules 40 from the server 20, and presents the received candidates for the combination of water treatment modules 40 to the user.

[0147] This makes it possible to prompt the user to change the combination of water treatment modules 40 in accordance with the predicted water demand.

[0148] FIG. 11 is a diagram showing a process flow in which the server 20 presents a combination of water treatment modules 40 to a user in accordance with the water treatment performance of the water treatment device 30. As shown in FIG.

[0149] In step S1153, the server 20 determines the user's water treatment purpose based on the sensing results of the water treatment device 30 by referring to the water treatment device database 282. For example, the server 20 holds information that specifies the expected amount of water treatment (the amount of water to be flowed into the water treatment module 40) for each purpose, and determines the frequency of use for that purpose by comparing the sensing results of the water treatment device 30 with the expected amount of water treatment. If the frequency of use of water treatment for a specific purpose is lower than a specified value, it can be determined that the user is not using the water treatment device 30 for that purpose.

[0150] Furthermore, when the frequency of use of the water treatment device 30 for a particular purpose is greater than a specified value, it can be determined that the user has relatively many opportunities to use the water treatment device 30 for that purpose.

[0151] In addition, when a use specified by the user is relatively frequently used, it can be estimated that the user is also using uses related to the use. For example, when the user specifies use for "dishwashing" and the water treatment module 40 purifies water using a filter or the like, the amount of water actually treated by the water treatment module 40 may be greater than the amount of water treatment expected for the use "dishwashing". In this case, the server 20 can estimate that the water treatment module 40 is also used for uses other than the use "dishwashing".

[0152] In step S1155, the server 20 identifies a combination of water treatment modules 40 to present to the user based on the results of determining the use based on the sensing results of the water treatment modules 40, and transmits the identified combination of water treatment modules 40 to the terminal device 10.

[0153] In step S1135, the terminal device 10 presents the combination candidates of the water treatment modules 40 received from the server 20 to the user.

[0154] As described above, it is possible to prompt the user to change the combination of the water treatment modules 40 based on the track record of water treatment in the water treatment device 30.

[0155] FIG. 12 is a diagram showing a process flow for prompting a user to move the water treatment device 30 in response to demand for water treatment in various locations.

[0156] In step S1353, server 20 predicts the demand for water treatment in each region based on the sensing results of water treatment devices 30 installed in each region and information on the environment of each region by referring to water treatment device database 282 and external environment information 284. For example, server 20 predicts the demand for water treatment in each region and the demand for water treatment devices 30 required to meet the demand (such as the number of water treatment devices 30) by performing the processes described in steps S1053 and S1153.

[0157] In step S1355, the server 20 acquires the status of where the water treatment devices 30 are located by referring to the water treatment device database 282. The server 20 determines the destination of the water treatment devices 30 in each region so as to satisfy the predicted demand for water treatment in each region predicted in step S1353. For example, when there is a first area in which the number of water treatment devices 30 is small compared to the predicted demand for water treatment in each region, the server 20 identifies a second area from among a plurality of areas in which the number of water treatment devices 30 is surplus to the prediction based on the distance to the first area, the travel time, and the amount of energy required to travel the water treatment device 30.

[0158] For example, based on the route to the first area (distance, road congestion, etc.) among the multiple areas, a second area with a short travel time to move the water treatment device 30 is identified. For example, when a drop in the supply of tap water or the like is expected in response to water demand, such as in the event of a disaster, the water treatment device 30 may be moved from an area with a short travel time in order to provide the water treatment function of the water treatment device 30 as quickly as possible in response to the water demand (to enable reuse of wastewater).

[0159] In addition, when it is expected that the demand for water treatment in various locations will fluctuate due to seasonal changes, etc., the water treatment device 30 to be moved may be identified so that the amount of energy required to move the water treatment device 30 is reduced (so that the amount of energy required for transportation is reduced).

[0160] In step S1357, the server 20 notifies the user of each water treatment device 30 of information on the destination of the water treatment device 30.

[0161] In step S1335, the terminal device 10 presents the destination of the water treatment device 30 to the user.

[0162] It is not necessary to associate the water treatment device 30 with information about the user who will be using the water treatment device. For example, the water treatment device 30 may be installed in a public facility or a highly public place (such as a park) and not associated with information about the user, or may be associated with information about the administrator. The water treatment device 30 may be driven from the first area to the second area by remote control through communication or by the water treatment device 30 automatically driving based on map information or the like.

[0163] <Screen example> A description will be given of screen examples in situations where information is notified to the user. As described above, the terminal device 10 or the water treatment device 30 presents information to the user, but in the following description of screen examples, an example in which information is presented by the terminal device 10 of the user will be described.

[0164] FIG. 13 is a diagram showing an example of a screen on the terminal device 10. As shown in FIG.

[0165] 13(A), 13(B), and 13(C) are examples of screens in which combinations of water treatment modules 40 according to the intended use of the water treatment device 30 are presented to the user.

[0166] Fig. 13(A) corresponds to the processing of steps S931 and S935. As shown in Fig. 13(A), the terminal device 10 displays a position display section 132A, a use display section 132B, a module information display section 132G, and operation buttons 132C on the display 132. The server 20 transmits, to the terminal device 10, information to be displayed on the terminal device 10 by referring to the water treatment device database 282.

[0167] The position display section 132A is an area for presenting to the user the position where the water treatment device 30 is installed.

[0168] The purpose display section 132B is an area for presenting the purpose set for the water treatment device 30 (for example, the purpose designated by the user) to the user.

[0169] The module information display section 132G is an area for presenting to the user a combination of water treatment modules 40 to be installed in the water treatment device 30. As shown in the module information display section 132G, the terminal device 10 displays a combination of modules required for the water treatment device 30 to exhibit the function of the purpose "shower", and water treatment modules 40 that the user does not own (water treatment modules 40 required for the user to receive the provision of a function according to the purpose from the water treatment device 30).

[0170] Operation button 132C is an area for displaying information for guiding a user on a method for installing water treatment module 40 in water treatment device 30. For example, in response to a user's operation of designating operation button 132C, terminal device 10 displays the position of a slot for installing each water treatment module 40 in water treatment device 30, which is displayed on module information display section 132G, and the like.

[0171] Fig. 13(B) corresponds to the process of step S1035. As shown in Fig. 13(B), the terminal device 10 displays the prediction result of the water demand at the location where the water treatment device 30 is installed and a combination of water treatment modules 40 that can match the water demand based on the prediction result, according to the prediction result of the water demand in each area, as shown in the module information display section 132G. For example, when a shortage of the supply amount relative to the water demand is predicted, the server 20 causes the terminal device 10 to display a combination of water treatment modules 40 that can resolve the shortage.

[0172] Fig. 13(C) corresponds to the process of step S1135. As shown in Fig. 13(C), the terminal device 10 displays the result of estimating the user's intended use based on the history of the user's use of the water treatment device 30, as shown in module information display section 132G. In module information display section 132G, the terminal device 10 displays a combination of water treatment modules 40 corresponding to the estimated intended use of the user.

[0173] The terminal device 10 may display, on that screen (a screen displaying water treatment modules 40 that the user does not own), a screen (or a button to transition to that screen) that enables the user to use the water treatment modules 40 that the user does not own by purchasing them, etc.

[0174] FIG. 13(D) shows a situation in which guidance is presented to the user for moving the water treatment device 30 in accordance with the demand for water in each area.

[0175] 13(D) corresponds to the process of step S1335. As shown in FIG. 13(D), the terminal device 10 displays on the display 132 a guidance display section 132J and a route display section 132K.

[0176] In addition, the water treatment device 30 may not be owned by a user, and may be installed in various locations and moved by automatic travel or transportation according to the predicted demand for water treatment.

[0177] 13(D) may be a screen presented to a manager who manages the water treatment device 30. In addition, FIG.

[0178] The guidance display section 132J is an area for displaying the destination of the water treatment device 30 when the water treatment device 30 is to be moved according to the predicted demand for water treatment in each area. The guidance display section 132J may display information on the time required to move the water treatment device 30 and the time when the water treatment device 30 should be moved.

[0179] The route display section 132K is an area for allowing the user to view a method for moving the water treatment device 30 from the current location to the destination and a moving route. For example, in response to a user's operation on the route display section 132K, a transition to a screen displaying a moving method or the like may be made, or information such as the moving route may be displayed on the route display section 132K.

[0180] As described above, the water treatment system 1 is configured so that the water treatment modules 40 can be rearranged according to the application in the water treatment devices 30 installed in various locations, and can meet a wide variety of water demands without requiring infrastructure costs such as large-scale water treatment facilities.

[0181] <Embodiment 2> A water treatment system according to another embodiment will be described. In the description of the second embodiment, the term "water treatment device" includes the "water treatment device 30" described in the first embodiment, and refers to a device that performs water treatment, such as removing foreign matter from water supplied to the environment or water that has been used, using a filter. In other words, the term "water treatment device" includes devices that perform water treatment other than the water treatment device 30. In addition, in the description of the second embodiment, the term "water utilization facility" refers to a facility that is installed in response to a situation in which a user utilizes water.

[0182] In the description of the second embodiment, a method for creating a trained model for predicting the demand for water and the water usage status in each environment, such as a house, an apartment building, a mobile object (camper, aircraft, etc.), when various water utilization facilities and water treatment devices (including the water treatment device 30 described in the first embodiment; that is, water treatment devices other than the water treatment device 30 are also installed in a house, etc.) are available in each environment, will be described. As described in the first embodiment, the environments in which water is used include outdoor land 5, indoor building 6, mobile object 7, etc.

[0183] In addition, in embodiment 2, it is described how the created trained model can be distributed to the water treatment device or the user's terminal (including the terminal device 10 described in embodiment 1), enabling various processes such as notifying the user of information and maintaining and managing the water treatment device.

[0184] FIG. 14 is a diagram showing an overview of a water treatment system 2 according to a second embodiment. As shown in the water treatment system 2, a server 20 receives and accumulates a water treatment data set, which is a data group outputted in association with water treatment, from various devices, such as a water treatment device (including the water treatment device 30), a water use facility, and a terminal device 10, disposed in each environment. For example, the server 20 receives, as a water treatment data set, sensing data sensed in a water use facility (61A, 61B, . . .) installed in an environment (60A, 60B) in which a water treatment device (including a water treatment device other than the water treatment device 30) operates, and various data sensed in association with the operation of the water treatment device (for example, the water treatment device 30A, 30B). The water use facility is a facility for a user to use water, and various water use facilities are prepared according to the situation in which the user uses water, such as a shower room, a kitchen, and a laundry. For example, various sensors may be provided in various water treatment modules installed in the water treatment device 30.

[0185] Here, the water treatment data set includes, for example, the following:

[0186] (A) Parameters for operating various hardware components of the water treatment system 2 -Parameters related to pump operation for water utilization facilities and water treatment equipment (1) Pump drive values ​​(voltage, current), cumulative drive time, and pump maintenance records (2) Pump service life

[0187] -Tank operation control parameters (1) Tank capacity, material, and service life (2) Fluctuations in tank capacity (3) Tank cumulative operating time and maintenance records

[0188] -Valve operation control parameters (1) Valve drive value (voltage, current), cumulative drive time, operation time / timing (2) Valve service life

[0189] (a) Sensing results Sensing results of various sensors capable of sensing underwater (for example, the following items can be sensed by sensors) (1) Flow rate, pressure, water level, temperature (2) pH, electrical conductivity, redox potential, alkalinity, ion concentration (3) Turbidity, color, viscosity, dissolved oxygen (4) Odor, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total nitrogen, residual chlorine, total phosphorus, total organic carbon, total inorganic carbon, total trihalomethanes (5) Detection results of microbial sensors, chemical oxygen demand, biological oxygen demand, (6) Cyanide, mercury, oil, surfactants (7) Detection results of optical sensors and TDS (Total Dissolved Solids) sensors (8) Mass spectrometry results, fine particles, zeta potential, surface potential

[0190] Gas sensor sensing results (for example, the following items can be sensed by the sensor) (1) Carbon monoxide, carbon dioxide, ammonia, methane, propane, propane alcohol, VOCs (volatile organic compounds), organic solvents, trimethylamine, methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, oxygen, nitrogen, chlorine, and flammable gases.

[0191] Image data (1) Monitoring image data of biological treatment tank (2) Tank monitoring image data (3) Filter monitoring image data (4) Piping monitoring image data

[0192] Water quality data (1) Data on water quality standards for drinking water (51 items, Ministry of Health, Labour and Welfare) (2) Sewage treatment data

[0193] (c) Other information Environmental information (1) Atmospheric pressure, temperature, and humidity (2) Information indicating the location of the environment

[0194] User Data (1) User attributes (gender, nationality, place of residence) (2) Usage pattern of the user (for cleaning, for drinking)

[0195] The server 20 generates a trained model based on the water treatment data set collected from the environments (60A, 60B) in which the water treatment device operates. For example, the server 20 generates the trained model by performing machine learning based on the water treatment data set accumulated by sensing in each of the environments (60A, 60B) in which the water treatment device operates. The server 20 may store the trained model in association with information identifying each of the environments (60A, 60B) in which the water treatment device operates.

[0196] The server 20 transmits the generated trained model to a computer such as the water treatment device 30 or the terminal device 10. Based on information identifying the environment in which the water treatment device operates, the server 20 transmits the trained model based on a water treatment data set obtained by sensing in the environment to the water treatment device 30 or the user's terminal device 10 associated with the information identifying the environment. This allows the server 20 to distribute the trained model to the water treatment device 30 or the terminal device 10 for each of the environments (60A, 60B) in which the water treatment device operates.

[0197] Here, the water utilization facilities and water treatment devices may be installed in one or more units in a single-family home, or in an apartment building. Water utilization facilities and water treatment devices may also be installed at campsites, travel destinations, temporary accommodations, etc. In addition, water utilization facilities and water treatment devices may be installed in commercial facilities such as restaurants. Water utilization facilities are installed in response to situations in which users use water, and may include, for example, the following situations.

[0198] As a situation where users use water, (a) users may use equipment for washing their bodies. Examples of places where equipment for washing their bodies are located include shower rooms, bathrooms, hand washing areas, foot washing areas, and areas for washing animals' bodies.

[0199] In one example, users use water in the following situations: (a) They use clothes-washing equipment, such as a washing machine.

[0200] As an example of a situation in which a user uses water, (c) the user may use a washing device for washing food and dishes, for example, in the kitchen.

[0201] In some cases, users may use water supply equipment, such as a water purifier to obtain drinking water or cooking water.

[0202] These water utilization facilities have pipes, faucets, etc. for supplying and discharging water, and record the amount of water used, etc. In addition, the water utilization facilities may be ones that use collected water (rivers, swamps, lakes, seawater, well water, rainwater) collected naturally, or ones that use treated water that has been treated in a water treatment device.

[0203] The water treatment device is provided with a filter, and can remove foreign objects that are equal to or larger than a certain size or length. For example, the water treatment device removes garbage, stones, soil, sand, hair, dirt, excrement, food, etc., using the filter.

[0204] The water treatment device is equipped with a reverse osmosis membrane, so that it can remove metal molecules and pesticide molecules.

[0205] These water treatment devices (including water treatment device 30) operate under computer control, allowing control of the flow rate of water to be treated by the water treatment device and the treatment that is performed on the water (which filter the water passes through).

[0206] For example, by controlling the operation of the valves of the water treatment device by a computer, it is possible to control which filter the water to be treated passes through in the water treatment device. For example, by controlling the valves, the water to be treated can be made to pass through one filter, multiple filters, or none of the filters.

[0207] For example, by controlling the operation of a pump in a water treatment device by a computer, the amount of water pumped by the pump and the water pressure can be controlled.

[0208] Furthermore, the water treatment facility and the water treatment device have various sensors to sense the change in water pressure and the amount of water. For example, the sensors include a pressure sensor, a flow rate sensor, an electrical conductivity sensor, an odor sensor, and the like. By providing a pressure sensor in the piping used in the water treatment facility or the water treatment device, the pressure of the water in the piping can be sensed. Furthermore, by providing a flow rate sensor and an odor sensor in the piping through which the treated water flows after being treated by the water treatment device, the amount of water treated by the water treatment device and the intensity of the odor can be sensed. For example, the electrical conductivity of the untreated water before being treated by the water treatment device can be sensed by an electrical conductivity sensor.

[0209] Such sensors are installed, for example, in pipes, faucets, and the like.

[0210] <Data Structure> FIG. 15 is a diagram showing the data structure of the external environment information 284 in the second embodiment.

[0211] As shown in FIG. 15, each record of the external environment information 284 includes information on each item, such as an “environment identification information (ID)” item, an “parameters affecting water demand in the environment” item, and an “sensing data of water treatment equipment” item.

[0212] The item "environment identification information (ID)" is information for identifying each environment in which the water treatment device operates. The environment in which the water treatment device operates refers to, for example, a house occupied by one or more households, a building used as a business establishment, a facility where multiple residences or businesses are concentrated, etc. The item "environment identification information (ID)" may include information on the location of the environment in which the water treatment device operates.

[0213] The item "Parameters affecting water demand in the environment" is a parameter related to the amount of water supply and the amount of water demand in the environment.

[0214] For example, for parameters related to the amount of water supply and the amount of water demand, environmental factors include the place and position where water is used, the circumstances under which water is used, temperature, humidity, vibration, air pressure, etc. Furthermore, factors based on the manner of use for these parameters include the method and purpose of using water, etc. Furthermore, temporal factors for these parameters include the frequency with which a user uses water, the time it takes to use water per use, etc. Specifically, the following may be included.

[0215] (i) Parameters that influence the motivation of consumers to use water include, for example, parameters of climatic conditions. The parameters of climatic conditions include the weather, temperature, humidity, wind speed, etc. in the environment (location) where the water treatment device is installed.

[0216] (ii) Parameters affecting the water demand include, for example, information on users who use water in the environment. For example, parameters affecting the water demand include information on the number of users who use water in the environment, and information on the number of people flowing in and out per unit time. In addition, parameters affecting the water demand may include information on the time period when people are staying in a house, etc.

[0217] (iii) The parameters relating to the supply amount of water supplied to the environment include, for example, information on water sources available in the environment. For example, the information on water sources may include information on the flow rate of rivers, the amount of groundwater, water quality, etc.

[0218] The item "sensing data of water utilization equipment" includes data that can be sensed in the environment (60A, 60B) in which the water treatment device operates. For example, if various sensors (gas sensors, etc.) are installed in the environment, the sensing results of the sensors are included. It also includes information on the computer-controlled operating status of water utilization equipment (tanks, etc.) installed in the environment (60A, 60B). It also includes information on water quality sensed by various sensors possessed by the water utilization equipment and the water treatment device.

[0219] As described above, the server 20 accumulates the water treatment data set acquired in the environment (60A, 60B) in which the water treatment device operates in the external environment information 284, etc., and performs machine learning based on the water treatment data set, thereby generating a trained model. Note that various methods such as deep learning can be used as the machine learning method.

[0220] Fig. 16 is a diagram showing the operation of each device constituting water treatment system 2 of embodiment 2. Note that, although water treatment device 30 described in embodiment 1 is illustrated as an example of the water treatment device, the present invention is not limited to this.

[0221] In step S1601, the water treatment device 30 transmits parameters for controlling the operation of the water treatment device 30 (such as drive values ​​for valve control of the water treatment device 30 and drive values ​​for pump control) and sensing data from various sensors (such as underwater sensors) of the water treatment device 30 to the server 20 as a water treatment data set.

[0222] In step S1653, the server 20 receives the water treatment data set for the water treatment device 30 in each environment from the water treatment device 30. The server 20 stores the received water treatment data set in the water treatment device database 282 in association with information identifying each water treatment device 30.

[0223] In step S1611, the terminal device 10 transmits data acquired in each environment as a water treatment data set to the server 20. The terminal device 10 transmits, for example, parameters affecting the demand for water in each environment, sensing data of water utilization facilities, and the like to the server 20.

[0224] In step S1655, the server 20 acquires data acquired in each environment from the terminal device 10 (or a computer other than the terminal device 10 in the environment) and accumulates the data in a database (such as the external environment information 284) as a water treatment data set. The server 20 accumulates the water treatment data set as a database in association with information specifying the environment in which the water treatment device operates (for example, information identifying a user who uses the environment, identification information of the water treatment device 30, location information where the water treatment device 30 is located, etc.).

[0225] In step S1657, the server 20 generates a trained model for each environment based on the water treatment data set acquired in each environment. The server 20 generates a trained model based on the various water treatment data sets in association with information identifying the environment in which the water treatment device 30 operates.

[0226] In step S1659, the server 20 transmits the trained model to the computer of each environment. The server 20 distributes the trained model generated for each environment to the terminal device 10 or the water treatment device 30 of each environment based on the information identifying each environment.

[0227] In step S1603, the water treatment device 30 receives the trained model from the server 20.

[0228] In step S1605, the water treatment device 30 presents the processing results using the trained model to the user.

[0229] In step S1613, the terminal device 10 receives the trained model.

[0230] In step S1615, the terminal device 10 presents the processing result using the trained model to the user.

[0231] In the above description of embodiment 2, an example has been described in which the trained model generated by the server 20 is distributed to the terminal device 10 or the water treatment device 30, and the terminal device 10 or the water treatment device 30 receives the trained model and presents the processing results based on the trained model to the user (S1605, S1615).

[0232] Alternatively, the server 20 may hold a trained model generated for each environment, and in response to an access from the terminal device 10 or the water treatment device 30 in each environment, perform processing based on the trained model and transmit the processing result to the terminal device 10 or the water treatment device 30. That is, the processing of steps S1605 and S1615 may be performed by the server 20, and the server 20 may transmit the processing result based on the trained model to the water treatment device 30 or the terminal device 10 in response to an access from the water treatment device 30 or the terminal device 10.

[0233] As described above, by performing processing by each device of the water treatment system 2, it is possible to distribute a trained model, for example, to each household. This makes it possible to perform processing based on water demand forecasts and present the processing results to users.

[0234] For example, presenting the processing results using the trained model to the user (S1605, S1615) includes the following.

[0235] (1) Water supply treatment For example, when the amount of water supplied to an environment may vary, it is possible to prompt adjustment of the amount of water used in each environment and the method of performing water treatment in the water treatment device. When water from a water source is shared by multiple people, the time and amount of water used may differ in each environment (e.g., each household). While predicting water demand according to fluctuations in weather conditions and the inflow and outflow of people (in the case of a tourist destination, estimated based on the number of users using the airport, the number of hotel reservations, etc.), it is possible to perform control such as reusing water treated in the water treatment device in each environment so that the amount of water supplied from the water source is not insufficient, based on the trained model generated for each environment.

[0236] (2) Estimating the functions required for water treatment For example, the terminal device 10 uses the trained model to predict the operation status of the pump of the water treatment device when the other information (e.g., weather information) changes, based on information on the pump drive value. For example, the terminal device 10 uses the trained model to obtain a forecast of weather information such as temperature, humidity, and wind speed, and estimates the demand for water in the case of the weather information shown in the forecast, based on the prediction of the operation status of the pump. The terminal device 10 uses the trained model to estimate the demand for water, and can estimate the functions required of the water treatment device 30 (e.g., a combination of water treatment modules 40 to be installed in the water treatment device 30, filters that can handle the predicted amount of water treatment, pump performance, piping specifications, etc.) according to the demand for water.

[0237] In addition, since the pump controls the flow rate and water pressure of the water passing through the filter installed in the water treatment device, the terminal device 10 can use the trained model to present the user with predicted electricity charges, present the user with the timing for filter replacement, and perform processing to place an order for filter replacement based on the filter inventory status.

[0238] (3) How to handle treated water The terminal device 10 predicts the properties of the water after treatment by the water treatment device by using the trained model, and determines the contents to be notified to the user according to the prediction result. For example, the terminal device 10 predicts the sensing results of various sensors of the treated water treated by the water treatment device when the sensing results of the untreated water to be flowed into the water treatment device fluctuate, thereby predicting the properties of the water after treatment by the water treatment device. For example, the terminal device 10 can determine whether the treated water can be directly flowed into a river, soil, etc. based on the properties of the water (such as the degree of removal of pollutants).

[0239] <Other Examples of the Configuration of the Water Treatment Device 30> The water treatment device 30 described above in the first and second embodiments has been described as a device in which a water treatment module 40 having a predetermined shape is inserted (fitted) into a water treatment module installation mechanism 32 (installation mechanisms 32A, 32B, ...), as described in Figure 4.

[0240] In addition, methods for connecting multiple water treatment modules 40 to each other, connecting the water treatment modules 40 to a mechanism for supplying the water to be treated, and connecting the water treatment modules 40 to a discharge mechanism for discharging the treated water may be, for example, as follows.

[0241] 17 is a diagram showing another example of the configuration of water treatment device 30. As shown in the figure, a plurality of water treatment modules 40 may be lined up and connected by piping 42. In addition, by providing a connection mechanism 43 for connecting to other water treatment modules 40 at a predetermined location on the exterior of the water treatment module 40, the plurality of water treatment modules 40 may be connected to each other by lined up, stacked, or the like.

[0242] 17(A) shows an example in which a plurality of water treatment modules 40 are arranged horizontally and connected by piping 42. For example, the water treatment modules 40 are arranged on the floor surface, and the piping 42 is connected to the water treatment modules 40. As shown in the figure, water treatment module 40A-01 and water treatment module 40A-02 are connected by piping 42. Furthermore, water treatment module 40A-02 and water treatment module 40A-03 are connected by piping 42.

[0243] The pipe 42 may have a structure in which the water to be treated flows in a branched manner, and the branching direction may be controlled by a valve.

[0244] 17(B) shows an example in which water treatment modules 40 are connected to each other by a mechanism provided in the water treatment module 40. For example, any surface, such as a side surface, of the water treatment module 40 has a mechanism for connecting to another water treatment module 40. For example, the water treatment module 40 may have a recess and a protrusion at any location, and the water treatment modules 40 may be combined with each other by fitting the recesses and protrusions together.

[0245] In the example of Fig. 17(B), a plurality of water treatment modules 40 are stacked to connect the respective water treatment modules 40. In the example of Fig. 17(B), water treatment modules 40A-01 and 40A-02 are connected to each other by a connection mechanism 43 (shown by a dotted line). Similarly, water treatment modules 40A-02 and 40A-03, and water treatment modules 40A-03 and 40A-04 are connected to each other by a connection mechanism 43.

[0246] As described above, whether the water treatment module 40 is inserted into the water treatment module installation mechanism 32 shown in Fig. 4 or a plurality of water treatment modules 40 are connected to each other as shown in Fig. 17, the water passing through the water treatment module installation mechanism 32, the piping 42, the connection mechanism 43, the filters provided in the water treatment module 40, etc. can be sensed by various sensor devices. The server 20 updates the water treatment device database 282 based on the sensing results of the water treatment device 30.
