[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (First embodiment)

[0012] Fig. 1 is a diagram showing a water treatment system according to a first embodiment. As shown in Fig. 1, a water treatment system 10 according to this embodiment includes a water treatment facility (ultrapure water production facility) 21 and an information processing device 100.

[0013] The water treatment facility 21 comprises a pretreatment facility 22, a primary pure water production facility 23, and a secondary pure water production facility (subsystem) 24. In this embodiment, the present invention will be described as being applied to the primary pure water production facility 23. The pretreatment facility 22 may be a facility used in general water treatment facilities, and is a facility that removes fine particles and the like from the supplied raw water. The secondary pure water production facility 24 may be a facility used in general water treatment facilities, and is a facility that removes trace amounts of ions, total organic carbon, and the like that could not be completely removed by the primary pure water production facility 23. The present invention can also be applied to the pretreatment facility 22 and the secondary pure water production facility 24.

[0014] The primary pure water production facility 23 includes a tank 200, water treatment devices 300, 400, 500, and 600, a conductivity meter 710, flow meters 720 and 740, and a valve 730. The information processing device 100, the conductivity meter 710, and the flow meters 720 and 740 may be directly connected to each other so as to be able to communicate with each other, or may be connected via a communication network. The information processing device 100, the conductivity meter 710, and the flow meters 720 and 740 may be connected to each other wirelessly or via a wired connection. Similarly, the information processing device 100 and the valve 730 may be connected to each other so as to be able to communicate with each other. The number of water treatment devices included in the primary pure water production facility 23 is not limited to the number shown in FIG. 1.

[0015] Tank 200 is a tank that stores treated water (pretreated water) supplied from pretreatment equipment 22. The pretreated water stored in tank 200 is pumped up using pump 700 and supplied to downstream water treatment device 300 as water to be treated.

[0016] In this embodiment, the water treatment device 300 is an ion exchange device. The water treatment device 300 removes ionic components from the water to be treated, which is supplied from the tank 200 using a pump 700. The water treatment device 300 is a non-regenerative cartridge polisher in which a mixed bed of cation exchange resin and anion exchange resin is packed. The water treatment device 300 may be an ion exchange device in which multiple beds of cation exchange resin and anion exchange resin are packed, or an ion exchange device in which a single bed of cation exchange resin or anion exchange resin is packed. The water treatment device 300 may also be a device other than an ion exchange device, or may be a device configured by combining an ion exchange device with another device.

[0017] In this embodiment, the water treatment device 400 is an RO membrane (reverse osmosis membrane) separation device. The water treatment device 400 separates, for example, ions and TOC (total organic carbon) from treated water treated in the water treatment device 300, and divides the treated water into permeate and concentrated water. Note that the water treatment device 400 may be a device other than an RO membrane separation device, or may be a device configured by combining an RO membrane separation device with another device.

[0018] In this embodiment, the water treatment device 500 is an EDI (electrolytic deionization device). The water treatment device 400, for example, desalinates treated water treated in the water treatment device 400 and separates the treated water into desalinated water and concentrated water. Note that the water treatment device 500 may be a device other than an EDI, or may be a device configured by combining an EDI with another device.

[0019] In this embodiment, the water treatment device 600 is a UV (ultraviolet) oxidation device. The water treatment device 600 irradiates treated water treated in the water treatment device 500 with ultraviolet light to decompose organic matter contained in the water to be treated. The treated water treated in the water treatment device 600 is supplied to the secondary pure water production facility 24. A portion of the treated water treated in the water treatment device 600 is returned to the tank 200 as circulating water. In other words, the tank 200 also stores circulating water, which is a portion of the treated water treated in the water treatment device 600. The treated water returned to the tank 200 may also be treated water treated in the water treatment device 500. In this case, if the water treatment device 500 is an EDI, the treated water may be desalinated water (permeate), concentrated water, or electrode water treated in the EDI. A valve 730 is provided in the circulation path, and the circulating water is passed through the circulation path based on the opening and closing of the valve 730.

[0020] Conductivity meter 710 is a measuring device that measures the conductivity of treated water treated by water treatment device 300. Conductivity meter 710 transmits the measured value to information processing device 100 as time-series data indicating the state of the water.

[0021] Flow meter 720 is a measuring device that measures the flow rate of treated water supplied from water treatment device 400. Flow meter 720 transmits the measured value to information processing device 100 as time-series data indicating the state of the water.

[0022] Flow meter 740 is a measuring instrument that measures the flow rate of treated water that is circulated as circulating water to tank 200, out of the treated water supplied from water treatment device 600. Flow meter 740 transmits the measured value to information processing device 100 as time-series data indicating the state of the water.

[0023] Although a conductivity meter and a flow meter are given as examples of measuring instruments for measuring the state of water in the primary pure water production facility 23, the measuring instruments for measuring the state of water may also be water quality meters that measure water quality (e.g., impurity concentration), resistivity meters, water thermometers, and pressure gauges that measure pressure. Furthermore, the number and positions of the measuring instruments are not limited to those shown in FIG. 1.

[0024] Fig. 2 is a diagram showing an example of components included in the information processing device 100 shown in Fig. 1. As shown in Fig. 2, the information processing device 100 shown in Fig. 1 has an acquisition unit 110, a data conversion unit 120, a display screen generation unit 130, and a display unit 140. Note that Fig. 2 shows main elements in this embodiment among the components included in the information processing device 100 shown in Fig. 1.

[0025] The acquiring unit 110 acquires time-series data indicating the state of water flowing through the water treatment system 10. Specifically, the acquiring unit 110 receives and acquires time-series data transmitted from the conductivity meter 710 and flow meters 720 and 740 disposed in the water treatment system 10. The acquiring unit 110 also acquires time-series data indicating the operating status of the water treatment system 10. This time-series data indicating the operating status is, for example, data indicating the open / closed state of the valve 730, the operating processes (water sampling process, regeneration process, blowing process, standby process, etc.), the ON / OFF state of the pump 700, etc., in numerical form, in a time series. The acquiring unit 110 may acquire this time-series data indicating the operating status from a preset operating schedule or may acquire it based on an external input. Alternatively, the acquiring unit 110 may acquire this time-series data indicating the operating status based on a control signal transmitted from a control unit (not shown) that controls the opening / closing of the valve 730 and the ON / OFF of the pump 700. When measurement values ​​(numeric values) are transmitted from the conductivity meter 710 and the flow meters 720 and 740 arranged in the water treatment system 10, the acquisition unit 110 may acquire the transmitted numerical values ​​and create time-series data using the acquired numerical values. The same applies to the time-series data indicating the operating status of the water treatment system 10.

[0026] The data conversion unit 120 converts first time-series data among the time-series data indicating the state of water acquired by the acquisition unit 110 into time-series condition data having multiple levels corresponding to the state of water indicated by the first time-series data. Specifically, for example, if the time-series data indicating the state of water acquired by the acquisition unit 110 is time-series data indicating the conductivity of water, the data conversion unit 120 converts the time-series data into time-series condition data with digital level values, where the conductivity is level "0" if it is less than a predetermined threshold and level "1" if it is equal to or greater than the threshold. Furthermore, if the time-series data indicating the state of water acquired by the acquisition unit 110 is time-series data indicating the pH of water, the data conversion unit 120 converts the time-series data into time-series condition data with digital level values, where the pH is level "0" if it is less than a predetermined threshold (e.g., "7") and level "1" if it is equal to or greater than the threshold. This threshold may not be one, but multiple thresholds may be set. Furthermore, the data conversion unit 120 converts first time series data among the time series data indicating the operating status of the water treatment system 10, acquired by the acquisition unit 110, into time-series status data having a plurality of levels corresponding to the operating status indicated by the first time series data. Specifically, for example, if the time series data indicating the operating status acquired by the acquisition unit 110 is time series data indicating the operating process of the water treatment system 10, the data conversion unit 120 converts the first time series data into time-series status data of digital level values ​​in which a time period in which the water treatment system 10 is in process A is designated as "2," a time period in which the water treatment system 10 is in process B is designated as "1," and a time period in which the water treatment system 10 is in process C is designated as "0." Furthermore, if the time series data indicating the operating status acquired by the acquisition unit 110 is time series data indicating the opening and closing of the valve 730, the data conversion unit 120 converts the first time series data into time-series status data of digital level values ​​in which a time period in which the valve 730 is in an open state is designated as "1" and a time period in which the valve 730 is in a closed state is designated as "0." The data conversion unit 120 may combine a plurality of pieces of time-series data indicating the state of water and time-series data indicating the operating status and convert them into time-series state data.For example, the data conversion unit 120 may generate time-series state data by combining the water sampling process of the water treatment device 300 with the open state of the valve 730 for returning treated water to the tank 200 to generate state data called a water sampling circulation state. Furthermore, when the data conversion unit 120 uses the operating process of the water treatment system as time-series data indicating the operating status, it may generate time-series state data in which the switching timing of each process in the operating process is shifted by a predetermined time.

[0027] The display screen generation unit 130 generates display screen data by superimposing the time-series status data converted by the data conversion unit 120 and second time-series data other than the first time-series data from which the time-series status data was converted, on a background of the time-series status data. The second time-series data in this case is time-series data indicating the state of water among the time-series data acquired by the acquisition unit 110. Specifically, the display screen generation unit 130 generates display screen data such that the background is time-series status data that allows multiple levels to be visually distinguished from one another. For example, the display screen generation unit 130 generates display screen data using time-series status data in which multiple levels are colored differently as a background. The different colors are colors that allow the different levels to be visually distinguished from one another when the display screen data is displayed. For example, the different colors may be colors that allow the different levels to be distinguished from one another even if they both belong to the same yellow family, such as a yellow close to green and a yellow close to blue. Alternatively, the display screen generation unit 130 generates display screen data using time-series status data in which multiple levels are patterned differently as a background. Alternatively, the display screen generating unit 130 generates display screen data using, as a background, time-series status data displayed in different shades among a plurality of levels. The time-series data and time-series status data that the display screen generating unit 130 superimposes may be externally selectable. Furthermore, color information for the color that the display screen generating unit 130 uses according to each level of the time-series status data may be externally selectable. Furthermore, the display screen generating unit 130 may generate display screen data in which a plurality of time-series status data (e.g., time-series status data of an operating process and time-series status data of a pump's ON / OFF) are superimposed on the time-series data. The display screen generating unit 130 outputs the generated display screen data to the display unit 140.

[0028] FIG. 3 is a diagram showing an example of a screen for externally selecting the time-series data and time-series status data to be superimposed on each other by the display screen generation unit 130 shown in FIG. 2. The screen shown in FIG. 3 may be displayed on the display unit 140 of the information processing device 100, or on the display unit of a communication device operated by a user that can communicate with the information processing device 100. FIG. 3 shows an example in which the time-series status data is data indicating an operating status (status data). As shown in FIG. 3, a "time-series data selection screen" for selecting the second time-series data described above is displayed. In the example shown in FIG. 3, "conductivity," "pressure," and "flow rate" are displayed as selectable items. In addition, a "status data setting screen" for selecting and setting the time-series status data described above is displayed. In the example shown in FIG. 3, "operating process," "valve open / close," and "pump on / off" are displayed as selectable items. It goes without saying that these data are data acquired by the acquisition unit 110. Furthermore, the status data setting screen also displays a screen for selecting the color in which the selected status data (time-series status data) should be displayed as a background. In the example shown in Fig. 3, "light blue," "yellow," and "gray" are displayed as selectable colors. These color types are preset in the information processing device 100. There is no particular limitation on the method for selecting a desired item (data) from the screen displayed in this manner.

[0029] The display unit 140 displays the display screen data output from the display screen generation unit 130. The display unit 140 may be a general display provided outside the information processing device 100. The display unit 140 may be, for example, a display of a PC (Personal Computer) or a display of a mobile terminal such as a smartphone.

[0030] Fig. 4 is a diagram showing an example of the display mode of display screen data on display unit 140 shown in Fig. 2. Fig. 4 shows an example in which the first time-series data from which the time-series state data is converted is the operating process (process A, process B, process C), and the second time-series data is the measurement data of conductivity meter 710 shown in Fig. 1. As shown in Fig. 4, the measurement data (conductivity) of conductivity meter 710, which is the second time-series data, is superimposed on the background of the time-series state data into which the time-series data of the operating process (process A, process B, process C), which is the first time-series data, is converted.

[0031] The following describes an information processing method in the information processing device 100 shown in Fig. 2. Fig. 5 is a flowchart for explaining an example of the information processing method in the information processing device 100 shown in Fig. 2. Here, an example will be described in which the first time series data is time series data indicating the operating status of the water treatment system 10, and the second time series data is time series data measured by a measuring instrument provided in the water treatment system 10.

[0032] First, the acquisition unit 110 acquires time-series data on the operating status of the water treatment system 10 as first time-series data. Furthermore, the acquisition unit 110 acquires time-series data measured by a measuring instrument (e.g., conductivity meter 710) provided in the water treatment system 10 as second time-series data (step S1). A specific method for acquiring the time-series data on the operating status may be the method described above. Then, the data conversion unit 120 converts status data selected from the first time-series data indicating the operating status acquired by the acquisition unit 110 according to the screen described with reference to FIG. 3 into time-series status data having multiple levels corresponding to the operating status (step S2). A specific method for converting the status data into time-series status data may be the method described above. Next, the display screen generation unit 130 acquires color information corresponding to each level of the time-series status data converted by the data conversion unit 120 (step S3). At this time, the display screen generation unit 130 acquires color information set according to the screen described with reference to FIG. 3. The display screen generation unit 130 colors each level of the time-series status data with the color indicated by the color information acquired in step S3 (step S4). The display screen generation unit 130 generates display screen data by superimposing the time-series data selected from the second time-series data acquired by the acquisition unit 110 in step S1 according to the screen described with reference to FIG. 3 on the background of the time-series status data colored in step S4 (step S5). Then, the display unit 140 displays the display screen data generated by the display screen generation unit 130 (step S6). The display form of the display screen data is, for example, the form shown in FIG. 4.

[0033] In this embodiment, measurement data measuring the water condition in the water treatment system and data measuring the water condition or data indicating the operating status are displayed superimposed in chronological order. The measurement data or data indicating the operating status used as the background is converted into level data corresponding to the measurement values ​​or operating status, and the level data, which allows each level to be distinguished from the other, is displayed superimposed on the measurement data as a background. By superimposing multiple data sets in chronological order and using one of the data sets as a background that allows the measurement values ​​or operating status levels to be distinguished, the correlations and influences of the multiple data sets are easily visualized, making it easier to identify the causes of water quality fluctuations. Furthermore, level data, colored in colors corresponding to each level, is displayed superimposed on the measurement data as a background. By superimposing multiple data sets in chronological order and using one of the data sets as a colored background, the correlations and influences of the multiple data sets are even more easily visualized, making it easier to identify the causes of water quality fluctuations. The time-series status data generated by the data conversion unit 120 and the display screen data generated by the display screen generation unit 130 may be stored in a storage means, such as a database, from which data can be read and written. In addition, the display screen generation unit 130 may generate display screen data in which multiple time-series status data (for example, time-series status data of the operation process and time-series status data of the pump ON / OFF, or time-series status data converted from time-series data indicating the water state and time-series status data of the operation process) are superimposed as a background. (Second embodiment)

[0034] Fig. 6 is a diagram showing a water treatment system according to a second embodiment. As shown in Fig. 6, a water treatment system 11 according to this embodiment includes a water treatment facility (ultrapure water production facility) 21 and an information processing device 101. The water treatment facility 21 is the same as that in the first embodiment.

[0035] Fig. 7 is a diagram showing an example of components included in the information processing device 101 shown in Fig. 6. As shown in Fig. 7, the information processing device 101 shown in Fig. 6 has an acquisition unit 110, a data conversion unit 120, a display screen generation unit 131, a display unit 140, and a time sliding unit 151. The acquisition unit 110, the data conversion unit 120, and the display unit 140 may be the same as those in the first embodiment. Note that Fig. 7 shows main elements in this embodiment among the components included in the information processing device 101 shown in Fig. 6.

[0036] The time sliding unit 151 slides the time of the time-series status data generated by the data conversion unit 120 by a predetermined time. Specifically, the time sliding unit 151 advances or delays the time of the time-series status data generated by the data conversion unit 120 by a predetermined time. In the following description, a process in which the time sliding unit 151 delays the time of the time-series status data by a predetermined time will be described as an example. The water stored in the tank 200 and the water treatment devices 300, 400, 500, and 600 shown in FIG. 6 remains in the tank 200 and the water treatment devices 300, 400, 500, and 600 for a predetermined time (retention time). Therefore, the time sliding unit 151 delays the time of the time-series status data, which are overlapped with each other, and the second time-series data, which is time-series data indicating the state of water acquired by the acquisition unit 110, by the retention time with respect to the time of the second time-series data. The residence times are set in advance in association with the tank 200 and each of the water treatment devices 300, 400, 500, and 600. For example, when checking the effect of the treatment in the water treatment device 300 (ion exchange device) on the water quality at the outlet of the water treatment device 600 (UV) shown in Fig. 6, the time of the time-series status data generated by the data conversion unit 120 based on the operating status (e.g., ON / OFF of the pump 700) related to the operation of the water treatment device 300 (ion exchange device) is delayed by the sum of the residence times (e.g., 3 hours) associated with each of the water treatment devices 300, 400, 500, and 600. Furthermore, when checking the impact of the treatment in the water treatment device 300 (ion exchange device) on the water quality at the outlet of the water treatment device 500 (EDI) shown in FIG. 6 , the time of the time-series status data generated by the data conversion unit 120 based on the operating status (e.g., ON / OFF status of the pump 700) of the water treatment device 300 (ion exchange device) is delayed by the sum of the residence times (e.g., 2 hours) associated with each of the water treatment devices 300, 400, and 500. This residence time may be a time input and set from an external device. Note that, for the time-series status data and the second time-series data that are to be superimposed on each other, the time sliding unit 151 may delay or advance the time of the second time-series data by the residence time relative to the time of the time-series status data. The time sliding unit 151 outputs the delayed time-series status data to the display screen generation unit 131.

[0037] The display screen generation unit 131 generates display screen data in which the delayed or advanced time-series state data output from the time sliding unit 151 is superimposed on second time-series data other than the first time-series data from which the time-series state data was converted, using the delayed or advanced time-series state data as a background. The display screen generation unit 131 outputs the generated display screen data to the display unit 140.

[0038] An information processing method in the information processing device 101 shown in Fig. 7 will be described below. Fig. 8 is a flowchart for explaining an example of the information processing method in the information processing device 101 shown in Fig. 7. Here, an example will be described in which the first time series data is time series data indicating the operating status of the water treatment system 11, and the second time series data is time series data measured by a measuring instrument provided in the water treatment system 11.

[0039] First, the acquisition unit 110 acquires time-series data of the operating status of the water treatment system 11 as first time-series data. The acquisition unit 110 also acquires time-series data measured by a measuring instrument (e.g., conductivity meter 710) provided in the water treatment system 11 as second time-series data (step S11). A specific method for acquiring the time-series data of the operating status may be the method described in the first embodiment. Then, the data conversion unit 120 converts status data selected from the first time-series data indicating the operating status acquired by the acquisition unit 110 according to the screen described with reference to FIG. 3 into time-series status data having multiple levels corresponding to the operating status (step S12). A specific method for converting the status data into time-series status data may be the method described in the first embodiment. The time sliding unit 151 delays the time of the time-series status data generated by the data conversion unit 120 by a predetermined time (step S13). A specific delay method is as described above. Next, the display screen generation unit 131 acquires color information corresponding to each level of the time-series status data delayed by the time sliding unit 151 (step S14). At this time, the display screen generation unit 131 acquires color information set in accordance with the screen described with reference to FIG. 3. The display screen generation unit 131 colors each level of the time-series status data with the color indicated by the color information acquired in step S14 (step S15). The display screen generation unit 131 generates display screen data in which the time-series status data colored in step S15 is used as a background and the time-series data selected from the second time-series data acquired by the acquisition unit 110 in step S11 in accordance with the screen described with reference to FIG. 3 is superimposed (step S16). Then, the display unit 140 displays the display screen data generated by the display screen generation unit 131 (step S17). The display mode of the display screen data may be the same as that in the first embodiment.

[0040] In this way, in addition to the first embodiment, in this embodiment, the time of the time-series status data overlaid as the background is delayed based on the water residence time in the necessary equipment.
