Both the recording medium 101 and the auxiliary storage device 102 correspond to computer-readable recording media.

  FIG. 3 is a diagram illustrating a functional configuration example of the chlorine information output device according to the embodiment of the present invention. In FIG. 3, the chlorine information output device 10 includes a request reception unit 11, a chlorine concentration estimation unit 12, a message generation unit 13, an information output unit 14, and the like. Each of these units is realized by processing executed by the CPU 104 by a program installed in the chlorine information output apparatus 10. The chlorine information output device 10 also uses a water source information storage unit 111, an examination site information storage unit 112, an address information storage unit 113, a water quality information storage unit 114, a message storage unit 115, and the like. Each of these storage units can be realized by using a storage device connected to the auxiliary storage device 102 or the chlorine information output device 10 via a network.

  The request receiver 11 receives a chlorine information provision request from the portable terminal 20. Chlorine information refers to information on the chlorine concentration of tap water. As an example of the information regarding the chlorine concentration, there is information indicating the chlorine concentration itself or a treatment (dechlorination treatment) according to the chlorine concentration. In the request, for example, position information of the current position of the mobile terminal 20 is specified. The chlorine concentration estimation unit 12 estimates the chlorine concentration at the position related to the position information specified in the request. The message generation unit 13 generates a message indicating a treatment or the like according to the estimated value of the chlorine concentration. The message is generated based on the message stored in the message storage unit 115. The information output unit 14 outputs a screen including the chlorine concentration estimated by the chlorine concentration estimation unit 12 and the message generated by the message generation unit 13.

  The water source information storage part 111 memorize | stores the name of the water purification plant used as the water source of the said area for every area. In the present embodiment, the water purification plant has significance as a chlorine input place. The inspection site information storage unit 112 stores position information and the like regarding each point where water quality inspection is performed (hereinafter referred to as “inspection site”). The address information storage unit 113 stores correspondence information between addresses and latitudes and longitudes. The water quality information storage unit 114 stores the result of the water quality test for each inspection site. In the present embodiment, the measured value of the chlorine concentration is stored as a result of the water quality test.

  Hereinafter, a processing procedure executed by the chlorine information output apparatus 10 will be described. FIG. 4 is a flowchart for explaining an example of the processing procedure of the chlorine information providing processing. In the description of FIG. 4, a user who receives the chlorine information providing service via the mobile terminal 20 is referred to as a “target user”.

  In step S <b> 101, the request reception unit 11 receives a chlorine information provision request from any of the mobile terminals 20. The request is displayed by the portable terminal 20 of the target user. It is transmitted from the portable terminal 20 in response to an input via the input screen as shown in FIG.

  FIG. 5 is a diagram illustrating a display example of the input screen. In FIG. 5, an input screen 510 includes a search point input area 511, a usage selection area 512, a setting button 513, a search button 514, and the like.

  The search point input area 511 is an area for inputting position information of the search point. A search point refers to a point or place that is a target for providing chlorine information. The position information may be, for example, an address or place name that is unrelated to the current position. Further, the position information may be specified by instructing a certain point (latitude and longitude) on the map displayed by the mobile terminal 20. The position information may be latitude and longitude measured by a GPS (Global Positioning System) function of the mobile terminal 20 or the like. In addition, a value input in the past (for example, a previous input value) may be selected as the position information.

  The use selection area 512 is an area for selecting the use of tap water at the search point. In FIG. 5, drinking water, aquarium water, infant milk, bathtub water, cooking, and the like are shown as examples of usage selection candidates.

  When the setting button 513 is pressed, the mobile terminal 20 displays a condition setting screen 520. The condition setting screen 520 is a screen for setting use conditions for each use of tap water. In FIG. 5, when the usage is aquarium water, the aquarium size is used. When the usage is bath water, the bath size is used. When the usage is infant milk, the date of birth of the baby can be input. In the condition setting screen 520, when a use condition corresponding to the application is input and the setting button 521 is pressed, the display target on the mobile terminal 20 returns to the input screen 510. In the example of FIG. 5, when the usage is potable water and cooking, the use condition may not be selected.

  When the search button 514 is pressed after the position information, usage, and use conditions of the search point are input, the portable terminal 20 requests the provision of chlorine information in which the position information, use, and use conditions of the search point are specified. Is transmitted to the chlorine information output device 10. In step S101, such a provision request is received.

  Subsequently, the chlorine concentration estimation unit 12 refers to the water source information storage unit 111 and identifies the water purification plant that is the water source of the search point (S102).

  FIG. 6 is a diagram illustrating a configuration example of the water source information storage unit. In FIG. 6, the water source information storage unit 111 stores the name of the water purification plant (water purification plant name) serving as the water source in association with the address. Therefore, in step S102, the name of the water purification plant corresponding to the address related to the location information of the search point is acquired from the water source information storage unit 111. In addition, the address memorize | stored in the water source information storage part 111 should just be specified to the level which can distinguish the area from which a water source differs. For example, if the water source is different for each municipality, the address only needs to be specified up to the municipality. When the position information of the search point is latitude and longitude, the water source information storage unit 111 may be referred to after the address of the area including the point of the latitude and longitude is specified. For example, identification of an address in an area including latitude and longitude points can be performed by a known technique using electronic map information or the like.

  Hereinafter, the water purification plant identified in step S102 is referred to as “water purification plant A”. Subsequently, the chlorine concentration estimation unit 12 specifies an inspection site of tap water using the water purification plant A as a water source with reference to the water source information storage unit 111, the inspection site information storage unit 112, and the like (S103).

  FIG. 7 is a diagram illustrating a configuration example of the examination site information storage unit. In FIG. 7, the inspection site information storage unit 112 stores the inspection site ID, address, latitude, longitude, and the like for each inspection site. The inspection site ID is identification information for each inspection site. The address is the address of the location where the inspection site is located. Latitude and longitude are the latitude and longitude of the inspection site.

  In step S103, for example, the address corresponding to the water purification plant A is specified using the water source information storage unit 111 (FIG. 6). One or more inspection site IDs corresponding to the address belonging to the area indicated by the address are specified with reference to the inspection site information storage unit 112. Hereinafter, the specified one or more search place groups are referred to as search place groups G. In addition, the water purification plant name may be previously stored in the inspection site information storage unit 112 in association with the inspection site ID.

  Subsequently, the chlorine concentration estimation unit 12 extracts an inspection site closest to the search point from the inspection site group G (S104). The distance between each search location included in the search location group G and the search location is based on the latitude and longitude stored in the examination location information storage unit 112 for each search location and the location information of the search location. It can be calculated. Note that when the location information of the search point is specified by an address, for example, the address information storage unit 113 may be referred to and the latitude and longitude corresponding to the address may be specified.

  FIG. 8 is a diagram illustrating a configuration example of the address information storage unit. In FIG. 8, the address information storage unit 113 stores the latitude and longitude in association with the address. The latitude and longitude are, for example, the latitude and longitude of the reference point in the range specified by the address.

  Note that the inspection site closest to the search point extracted in step S104 is hereinafter referred to as “inspection site B1”.

  Subsequently, the chlorine concentration estimation unit 12 determines whether or not the distance from the search point to the inspection site B1 is equal to or less than a preset threshold value α (S105). The threshold value α may be a distance at which the chlorine concentration is likely to change, for example. That is, normally, the concentration of chlorine that is input at a water purification plant decreases in the process of water flowing through the water pipe (the passage of time). In order to maintain the reference value at the end of the water pipe at the water purification plant, chlorine is introduced in consideration of the distance of the water distribution pipe, the time during which the water flows, and the like. Naturally, the closer to the water purification plant, the higher the chlorine concentration, and the farther away from the water purification plant, the lower the chlorine concentration. In view of such circumstances, the threshold α may be a distance at which the chlorine concentration is likely to change. That is, the threshold value α is a threshold value for determining whether or not to estimate the chlorine concentration at the search point based on the chlorine concentration at the inspection site B1. Therefore, as long as it is possible to determine whether or not to estimate the chlorine concentration at the inspection site B1, the determination in step S105 may be performed by another method. For example, it may be determined whether or not the difference between the distance from the water purification plant A to the search point and the distance from the water purification plant A to the search site B1 is within a predetermined value.

  When the distance from the search point to the inspection site B1 is equal to or less than the threshold value α (Yes in S105), the chlorine concentration estimation unit 12 acquires the measured value of the chlorine concentration in the inspection site B1 from the water quality information storage unit 114 (S106). ). That is, the measured value is estimated as the chlorine concentration of tap water at the search point.

  FIG. 9 is a diagram illustrating a configuration example of the water quality information storage unit. In FIG. 9, the water quality information storage unit 114 stores an inspection site ID, an inspection date, an inspection time, a chlorine concentration, a latitude and a longitude, a water source, and the like for each inspection site.

  The inspection date and the inspection time are the date and time when the water quality inspection was last performed at the inspection place related to the search place ID. Chlorine concentration is the chlorine concentration measured in the last water quality test. Latitude and longitude are the latitude and longitude of the search location. The water source is the name of the water purification plant that is the water source of the inspection site. Note that the latitude and longitude of each inspection location are stored in the inspection location information storage unit 112. Therefore, the latitude and longitude may not necessarily be stored in the water quality information storage unit 114. Moreover, the inspection place which uses each water purification plant as a water source can be specified by the method demonstrated in step S103. Therefore, the water source does not necessarily have to be stored in the water quality information storage unit 114. Alternatively, in step S103, the water quality information storage unit 114 may be referred to specify the inspection site group G that uses the water purification plant A as a water source.

  Subsequently, the message generation unit 13 acquires a message corresponding to the estimated value of the chlorine concentration at the search point, the use of the tap water specified in the chlorine information provision request, the use condition, and the like from the message storage unit 115 ( S107).

  FIG. 10 is a diagram illustrating a configuration example of the message storage unit. In FIG. 10, the message storage unit 115 stores a message for each use, condition, and chlorine concentration. In step S107, the values of the usage and conditions match the usage and usage conditions of tap water specified in the chlorine information provision request, and the chlorine concentration value matches the estimated chlorine concentration value at the search point. A message is acquired from the message storage unit 115.

  Note that a range may be specified for the chlorine concentration of each record in the message storage unit 115. In the present embodiment, the chlorine concentration of a certain record corresponds to a range that is equal to or higher than the chlorine concentration and less than the chlorine concentration of the next record having the same use and conditions. In addition, if there is no record that includes conditions that match the use conditions specified in the chlorine information provision request, records that match the usage and chlorine concentration are extracted, and the message of the record is the condition for the record of the use condition swimming. May be edited based on the relationship. For example, when the usage condition is 40L and the condition of the record is 20L, the storage time, the amount of sodium thiosulfate, etc. are changed based on a preset calculation formula such as double. May be.

  Subsequently, the information output unit 14 returns screen data for displaying a response screen including the chlorine concentration at the search point and the acquired message to the portable terminal 20 of the target user (S114). The portable terminal 20 displays a response screen based on the screen data.

  FIG. 11 is a diagram illustrating a display example of a response screen. FIG. 11 illustrates three response screens. The response screen 530a is an example of a response screen that is displayed when potable water is selected as the use and the estimated chlorine concentration at the search point is 0.20 mg / L.

  The response screen 530b is an example of a response screen that is displayed when aquarium water is selected as the application, 20L is selected as the condition, and the estimated chlorine concentration at the search point is 0.40 mg / L.

  The response screen 530c is an example of a response screen that is displayed when infant milk is selected as an application, meets the conditions of two months after birth, and the estimated chlorine concentration at the search point is 0.30 mg / L. .

  On each response screen, the estimated value of the chlorine concentration at the search point and the message acquired from the message storage unit 115 are displayed as “latest chlorine concentration” and “water use advice”. For example, a user who refers to the message (“water use advice”) can grasp necessary work regarding dechlorination processing and the like. In addition, a user who is familiar with the dechlorination treatment according to the chlorine concentration can grasp necessary work regarding the dechlorination treatment and the like by referring to the chlorine concentration. Only one of the chlorine concentration and the message may be displayed.

  In addition, as shown in FIG. 11, other information such as a water station notice may be displayed on the response screen.

  On the other hand, when the distance from the search point to the inspection site B1 exceeds the threshold α in step S105 (No in S105), the chlorine concentration estimation unit 12 calculates the distance L1 from the search point to the water purification plant A (S108). . The value of the distance L1 can be calculated based on the latitude and longitude of the search point and the latitude and longitude with respect to the water purification plant A. The latitude and longitude for the water purification plant A are identified by referring to the water source information storage unit 111 and the address for the water purification plant A, and the latitude and longitude corresponding to the address are identified by referring to the address information storage unit 113. Can be specified. In addition, the latitude and longitude of the location may be previously memorize | stored in the memory | storage device for every water purification plant.

  Subsequently, the chlorine concentration estimation unit 12 extracts a test site in the test site group G whose distance from the water purification plant A is closest to the distance L1 (the difference between the distance and the distance L1 is minimum). (S109). The distance from each inspection site to the water purification plant A can be calculated based on the latitude and longitude of the water purification plant A and the latitude and longitude stored in the inspection site information storage unit 112 for each inspection site. Hereinafter, the extracted inspection place is referred to as “search place B2”. The distance from the inspection site B2 to the water purification plant A is referred to as “distance L2.”

  Subsequently, it is determined whether or not the difference between the distance L1 and the distance L2 is equal to or less than the threshold value β (S110). The threshold value β may be the same value as the threshold value α, or may be a value less than the threshold value α. By setting the threshold value β to a value less than the threshold value α, the conditions for the validity of the estimation of the chlorine concentration at the search point based on the measurement value of the chlorine concentration at the inspection site located relatively far from the search point may be tightened. it can. That is, there is a possibility that the route of tap water from the water purification plant is significantly different from the search point in the inspection place relatively far from the search point. The degree of decrease in chlorine concentration is affected not only by the distance of the route from the water purification plant, but also by the environmental conditions in the route. Therefore, by setting the threshold value β for the inspection site relatively far from the search point to be less than the threshold value α, the inspection site used for estimating the chlorine concentration at the search point is extracted under severe conditions in consideration of differences in environmental conditions. be able to.

  When the difference between the distance L1 and the distance L2 is equal to or less than the threshold β (Yes in S110), the chlorine concentration estimation unit 12 displays the chlorine concentration of the inspection site B1 and the chlorine concentration of the inspection site B2 in the water quality information storage unit 114. (S111). Subsequently, the chlorine concentration estimation unit 12 selects a higher value from the two acquired chlorine concentrations as an estimated value of the chlorine concentration at the search point (S112). This is because a higher value is more likely to provide a highly safe response for the user. Note that the chlorine concentration of the inspection site with a new inspection date and time may be selected as the estimated value of the search point instead of based on the level of the chlorine concentration. Subsequently, based on the estimated value of the chlorine concentration at the search point, the processes after step S114 are executed.

  In step S110, when the difference between the distance L1 and the distance L2 exceeds the threshold β (Yes in S110), the message generator 13 generates an error message indicating that the chlorine concentration cannot be estimated, for example (S113). . In this case, in step S114, screen data of a response screen for displaying the error message is returned.

  In the above embodiment, an information processing device other than the portable terminal 20 such as a desktop PC (Personal Computer) may be used as the client of the chlorine information output device 10. Alternatively, the chlorine information output device 10 may be directly operated by the user. The case where the device other than the portable terminal 20 is a client or the case where the chlorine information output apparatus 10 is directly operated by the user is effective when the user wants to know a chlorine location in a location different from the current location. As an example of such a place, an outing destination such as a travel destination, a moving destination or a moving destination candidate value, and the like can be given. When the chlorine information output device 10 is directly operated, the input screen 510, the response screen 530, and the like may be output to a display device connected to the chlorine information output device 10.

  Subsequently, an example of a system for periodically updating the information stored in the water quality information storage unit 114 will be described, for example. FIG. 12 is a diagram illustrating a configuration example of a water quality information update system. In the water quality information update system 2 shown in FIG. 12, the water quality information update device 30 can communicate with a plurality of automatic measuring devices 40 or a plurality of inspector terminals 50 via a network such as a mobile communication network or the Internet. Has been.

  The automatic measuring device 40 is a device that is installed at an inspection site and automatically and periodically performs measurement of tap water quality at the inspection site. In FIG. 12, the automatic measurement device 40 includes a water quality measurement unit 41, a position measurement unit 42, a time measurement unit 43, a data generation unit 44, a data transmission unit 45, and the like.

  The water quality measurement unit 41 is a sensor or the like for measuring water quality. In the present embodiment, the chlorine concentration may be measured. The position measuring unit 42 is, for example, a GPS receiver or the like, and measures the automatic measuring device 40, that is, the position information of the inspection site. However, in the present embodiment, the location information of the inspection location is stored in the inspection location information storage unit 112 or the like. Therefore, the inspection place ID may be stored in the automatic measurement device 40.

  The time measuring unit 43 is, for example, a clock. The data generation unit 44 generates data including a chlorine concentration that is a measurement value by the water quality measurement unit 41, position information that is a measurement value by the position measurement unit 42, date and time that is a measurement value by the time measurement unit 43, and the like. The data transmission unit 45 transmits the generated data to the water quality information update device 30.

  On the other hand, the inspector terminal 50 is a terminal used by a water quality inspector. For example, a mobile phone, a smartphone, a tablet terminal, a PC (Personal Computer), or the like may be used as the inspector terminal 50. In FIG. 12, the inspector terminal 50 includes, for example, an input unit 51, a data generation unit 52, a data transmission unit 53, and the like.

  The input unit 51 receives an input of a water quality test result from the inspector. The water quality inspection itself is performed using a separate dedicated device. The inspection result is input via an inspection result input screen as shown in FIG. 13, for example.

  FIG. 13 is a diagram illustrating a display example of an inspection result input screen. In the inspection result input screen 540 shown in FIG. 13, the chlorine concentration, color, odor, inspection date, inspection time, inspection location, and the like can be input. The inspection location may be specified by the inspection location ID, or may be specified by position information measured by the GPS function of the inspector terminal 50.

  When necessary items are input on the inspection result input screen 540 and the transmission button 541 is pressed, the data generation unit 52 generates data including the input items. The data transmission unit 53 transmits the transmitted data to the water quality information update device 30.

  The water quality information update device 30 includes a data receiving unit 31, a data registration unit 32, and the like. The data receiving unit 31 receives data transmitted from the inspector terminal 50 or the automatic measuring device 40. The data registration unit 32 updates the record in the water quality information storage unit 114 based on the received data.

  The chlorine information providing system 1 provides information on the chlorine concentration with higher accuracy by periodically updating the chlorine concentration and the like stored in the water quality information storage unit 114 by the water quality information updating system 2 as described above. be able to. The water quality information update device 30 may constitute a part of the chlorine information output device 10.

  As described above, according to the present embodiment, it is possible to estimate the chlorine concentration at the search point designated by the user and to provide the user with information related to the chlorine concentration. Therefore, the information regarding the chlorine concentration in the place where the user of tap water is interested can be provided.

  The estimation of the chlorine concentration at the search point is performed based on the measured value of the chlorine concentration at the inspection site nearest to the search point. Therefore, an estimated value with high reliability can be obtained.

  If the location of the nearest inspection site is not within the threshold α from the search point, the distance from the water treatment plant is the chlorine concentration of the inspection site closest to the distance from the water treatment plant to the search point. Based on this, the chlorine concentration at the search point is estimated. Since the chlorine concentration has a correlation with the distance from the water purification plant (the place where chlorine is introduced), an estimated value within a reasonable range can be obtained with respect to the chlorine concentration at the search point by such an estimation method.

  In addition, the inspection value used for estimating the chlorine concentration at the search point is extracted from the inspection site having the same search point and water source (water purification plant). Chlorine input may vary depending on the water treatment plant. Therefore, it cannot be said that the measured value at the inspection site using a water purification plant different from the water purification plant serving as the water source at the search point is necessarily highly reliable as a basis for estimating the chlorine concentration at the search point. Therefore, the reliability of the estimated value can be improved by using an inspection site having the same search point and water source (water purification plant) for estimating the chlorine concentration at the search point.

  In the present embodiment, the inspection site is an example of a chlorine concentration measurement point. The inspection site information storage unit 112 is an example of a first storage unit. The water quality information storage unit 114 is an example of a second storage unit. The water source information storage unit 111 is an example of a third storage unit. The search point is an example of a first position. The chlorine concentration estimation unit 12 is an example of an extraction unit. The information output unit 14 is an example of an output unit.
