Such measurement may be performed by a measurer such as a measurement company in response to a request of a measurement requester (government office or the like) who needs the measurement result, for example.

For example, when measurement is performed in the above manner, not only the measured value but also incidental information (or annotation information) related to the measured value such as the measurement date and time, the measurement position, and the peripheral image of the measurement site is recorded, and each of them is recorded. It is necessary to manage the measured value and incidental information in association with each other. In particular, in the case of outdoor water quality measurement, the measurement position as incidental information is used for the purpose of ensuring the truthfulness of the measured value or for follow-up survey when the measured value is an abnormal value. Information on the surrounding image of the measurement site is important.

Conventionally, in general, a measurer records a value measured by a measuring device together with a measurement date and time in a notebook or the like at a measurement site, and then outputs a transcription in a predetermined format by using a personal computer or the like and reports it to a measurement requester. .. In addition, the measurer may acquire the information of the measurement position and the information of the peripheral image of the measurement site, post it in the above format by using a personal computer, and report it to the measurement requester. Conventionally, in general, a separate GPS terminal is required to acquire information on the measurement position, and a separate camera is required to acquire a peripheral image of the measurement site. Then, in order to associate the measured value with the incidental information, it is necessary to input each information into a personal computer and aggregate it by inputting data using a keyboard or moving data using a memory card.

In addition, Patent Document 1 proposes a management system used for water quality inspection of pool water. This management system has a measurement result transmission unit equipped with a portable communication device and a measurement member, and a management server, and associates the measurement result information with the timing information related to the date or time in the storage unit of the management server. At the same time as storing, the remaining amount information on the remaining amount of the measuring reagent stored in the storage unit of the management server is reduced and updated.

When the water quality meter operation unit 205 outputs a communication start instruction (standby start instruction for connection request) by the operator, the water quality meter control unit 203 connects from the information device 3 via the first communication unit 208. When the request is waited for (S101) and the connection request is received, the water quality meter 2 and the information device 3 are communicably connected in response to the request (S102). In this embodiment, the first communication unit 208 and the second communication unit 309 are connected according to the Bluetooth (registered trademark) standard, and the water quality meter 2 and the information device 3 are connected in advance according to a predetermined procedure before starting this procedure. It is assumed that pairing with is performed. Next, the water quality meter control unit 203 receives the current date and time information from the information device 3 via the first communication unit 208, and the date and time information generated by the water quality meter clock unit 207 is input to the clock unit 305 of the information device 3. Synchronizes with the date and time information generated by (corrects the date and time information generated by the water quality meter clock unit 207) (S103). It should be noted that the synchronous processing of the clock information is not indispensable, and the processing may be arbitrarily performed, or the processing may not be provided. Next, the water quality meter control unit 203 obtains the measured value information (pH value and temperature value) according to the output of the sensor unit 201, and the water quality meter obtains the measured date and time information which is the date and time information when the measured value information is acquired. It is acquired from the clock unit 207 (S104), and the measured value information and the measured date and time information are transmitted to the information device 3 via the first communication unit 208 (S105). The processes of S104 and S105 are repeated at predetermined time intervals, for example, until the communication between the water quality meter 2 and the information device 3 is completed (S106). That is, the water quality meter 2 sequentially transmits the measured value information and the measurement date / time information to the information device 3. The communication end instruction (disconnection request) may be output from the water quality meter operation unit 205 and input to the water quality meter control unit 203 by the operation of the water quality meter operation unit 205 by the operator, or the information device 3 by the operator. It may be output from the information device 3 by the operation of the operation unit 303 and input to the water quality meter control unit 203 via the first communication unit 208. Further, although it is described here that the date and time information generated by the water quality meter clock unit 207 provided in the water quality meter 2 is used as the measurement date and time information, the time based on the date and time information generated by the clock unit 305 provided in the information device 3 is used. Stamps may be used. In this case, the control unit 301 of the information device 3 acquires the date and time information generated by the clock unit 305 each time the measured value is received from the water quality meter 2, and uses it as the measurement date and time information.

<Connection processing and recording processing in information equipment>
FIG. 3B is a flowchart showing an outline of a procedure from connection processing in the information device 3 to recording processing of water quality data in the water quality data management application 3a. Here, it is assumed that the operation unit 303 outputs a start instruction of the water quality data management application 3a by the operation of the operator before starting this procedure, and the control unit 301 activates this application 3a. ..

The control unit 301 uses the water quality meter 2 via the second communication unit 309 by invoking the application 3a or in response to a predetermined operation (such as tapping a predetermined button) from the operation unit 303 specified in the application 3a. A connection request is sent to the information device 3 and the water quality meter 2 is communicably connected (S201). As described above, it is assumed that the water quality meter 2 and the information device 3 have been paired in advance according to a predetermined procedure before starting this procedure. Next, the control unit 301 transmits the current date and time information acquired from the clock unit 305 to the water quality meter 2 via the second communication unit 309 (S202). As described above, this clock information synchronization process is not essential. Further, this clock information synchronization process may be performed by this application 3a after the application 3a for water quality data management is started, or is performed by another program such as a basic OS before the application 3a is started, for example. May be good. Further, the control unit 301 causes the display unit 304 to display a home screen as shown in G01 of FIG. 9A (S203). In this embodiment, the measured value information and the measurement date / time information sequentially transmitted from the water quality meter 2 to the information device 3 are sequentially updated and displayed on the home screen G01. That is, when the home screen G01 is displayed on the display unit 304, the control unit 301 receives the measurement value information (pH value and temperature value) and the measurement date / time information from the water quality meter 2 via the second communication unit 309. Is sequentially received, and the measured value information and the measured date and time information are sequentially updated and displayed on the home screen G01 on the display unit 304. In addition, a "recording mode selection" button is displayed on the home screen G01. In this embodiment, the water quality data management application 3a is provided with each mode of "current value recording", "continuous recording", "intermittent recording", and "log data acquisition" as recording modes. Then, the control unit 301 can perform a predetermined operation of the operator, in this embodiment, by tapping any of the above "recording mode selection" buttons displayed on the home screen G01, from the operation unit 303 to any of the above recording modes. When the selection instruction is output, the process proceeds to the recording process of the water quality data in the selected recording mode (S204). Hereinafter, the water quality data recording process (management process) in each of the above recording modes in S204 will be described.

<Record of current value>
FIG. 4 is a flowchart showing an outline of a procedure for recording water quality data in the “recording current value” mode.

When the operation unit 303 outputs a selection instruction of the "current value recording" mode by the operation of the operator, the control unit 301 is in the "recording current value" mode as shown in G02 of FIG. 9A on the display unit 304. Display the standby screen. The flowchart of FIG. 4 shows the procedure after the standby screen G02 is displayed. The control unit 301 sequentially receives the measured value information (pH value and temperature value) and the measured date and time information from the water quality meter 2 via the second communication unit 309 (S301), and the measured value information and the measured date and time information Is sequentially updated and displayed on the standby screen G02 on the display unit 304 (S302). Further, when the standby screen G02 is displayed on the display unit 304, the control unit 301 acquires the current position information from the position information acquisition unit 306 and appropriately updates the position information to the standby screen G02 on the display unit 304. To display. Further, when the standby screen G02 is displayed on the display unit 304, the control unit 301 acquires the peripheral image information currently stored in the finder from the camera 307, and the peripheral image information is standby on the display unit 304. The screen G02 is updated and displayed as appropriate.

Then, when the control unit 301 outputs a recording instruction of the current value from the operation unit 303 by a predetermined operation of the operator, or by tapping the "record current value" button displayed on the standby screen G02 in this embodiment. (S303), the measured value information and the measured date / time information currently displayed on the display unit 304 are recorded together with the current position information in association with each other in the csv file (S304). This csv file is temporarily stored in the storage unit 302. Further, the control unit 301 captures a peripheral image of a still image or a moving image with the camera 307 in synchronization with the execution of this recording, and associates the peripheral image information acquired from the camera 307 with the measured value information or the like into an image file. Record (S305). This image file is temporarily stored in the storage unit 302. The format of the image file is not particularly limited as long as it can be handled by the application 3a (and the application 5a) (JPEG format can be exemplified for a still image, and MPEG format can be exemplified for a moving image). For example, in the case of a still image, it is possible to shoot at substantially the same time by tapping the "record current value" button displayed on the standby screen G02. Further, in the case of a moving image, for example, by tapping the "record current value" button displayed on the standby screen G02, shooting can be started substantially at the same time. Then, in response to the tap of the "shooting end" button displayed on the screen as shown in G03 of FIG. 9A displayed on the display unit 304 by the control unit 301, the shooting is terminated substantially at the same time. Can be done. Note that storing (storing or recording) the measured value information and the incidental information in association with each other means that the control unit 301 is acquired in relation to the specific measured value information and is stored so that it can be identified as the incidental information. (That is, storing the information so that it can be identified that it is not the incidental information acquired in response to other measured value information). The specific association method is not limited to recording in a csv file to partition the information group, and a method such as tagging each information may be used.

Next, the control unit 301 displays the measured value information recorded as described above in association with the incidental information (measurement date / time information, measurement position information, peripheral image information), as shown in G04 of FIG. 9B. The screen is displayed on the display unit 304 (S306). In this embodiment, the measurement value information and incidental information (measurement date / time information, measurement position information, peripheral image information) associated with each other are aggregated and displayed on this browsing screen. It should be noted that the term "consolidated on one screen" includes the case where the entire display can be displayed by changing the display range by scrolling or the like. In addition, part of the information aggregated on this one screen is omitted (for example, thumbnail display of images and link display), and the entire information is enlarged or moved to the link destination by a predetermined operation. May be able to be displayed. Further, in this embodiment, by tapping the "MAP" button displayed in association with the measurement position information of the browsing screen G04, at least the measured value information and the incidental information are displayed as shown in the screen of G05 of FIG. 9B. A part (for example, measurement date / time information and measurement position information) can be displayed together with the map. The map may be displayed by using a program function different from that of the water quality data management application 3a such as the basic OS. In addition, to display the measured value information and the incidental information in association with each other means to display the measured value information so that the viewer can identify the acquired incidental information in relation to the specific measured value information (that is, other measurement). (Display so that it can be identified that it is not incidental information acquired in response to the value information). The specific association method is not limited to aggregating on one screen, and a method such as displaying on a plurality of screens linked so that they can be exchanged with each other may be used.

Here, on the browsing screen G04, the contents of the measured value information, the measurement date / time information as incidental information, the measurement position information, and the peripheral image information cannot be changed. Specifically, in this embodiment, the display of the measured value information, the measured date and time information, and the measured position information is not editable. Further, the peripheral image information acquired in synchronization with the recording of the measured value information as described above cannot be edited or replaced (it may be possible to delete the peripheral image information). On the other hand, the browsing screen G04 is provided with a title input field a, a comment input field b, an incidental information addition button c, and the like. The operator can input the title (character information) in the title input field a by the character information input function of the operation unit 303 or the voice recognition function using the microphone 308, if necessary. If the title is not particularly input, a default title such as the measurement date and time may be added. Further, the operator can input a comment (character information) in the comment input field b by the character information input function of the operation unit 303 or the voice recognition function using the microphone 308, if necessary. It should be noted that a comment based on the voice information itself may be input. Further, the operator can take a peripheral image (either a still image or a moving image) from another angle, for example, by operating the incidental information addition button c as needed. Further, by operating the incidental information addition button c, the above-mentioned arbitrary attached file (PDF file, separately acquired image file, etc.) can be added so as to be associated with the measured value information. The control unit 301 records the title and comment as incidental information in a text file (or a voice file if the comment is voice information) in association with the measured value information. This text file (or voice file when the comment is voice information) is temporarily stored in the storage unit 302. The format of the text file and the audio file is not particularly limited as long as it can be handled by the application 3a (and the application 5a). Further, the control unit 301 temporarily stores the additional incidental information such as the additional image information in the storage unit 302 in association with the measured value information.

Next, when the control unit 301 outputs a save instruction from the operation unit 303 by tapping the predetermined operation of the operator, or the "save record" button displayed on the browsing screen G04 in this embodiment, the water quality data An archive file including the above-mentioned measured value information and incidental information is generated as a file and stored in the storage unit 302 (S307). At this time, in this embodiment, the control unit 301 has the following two layers of the structure of the water quality data file as shown in FIG. 8 (b). First, the csv file recorded as described above and the image file acquired in synchronization with the recording of the measured value information are put together in a first archive file in which a private password is set. This password is set in the application 3a in advance by the provider of the water quality measurement system 1, for example, in a state of being private to the user. The password may be appropriately updated by the provider of the water quality measurement system 1 in association with the update of the application 3a (and the application 5a). The files contained in this first archive file cannot be changed later. In addition, the text file of the title and comment edited as described above (audio file if the comment is audio information) and additional incidental information such as additional image information are further added together with the first archive file described above. Put together in a second archive file. Since no password has been set for this second archive file, the included files can be arbitrarily replaced later. The first archive file and the second archive file are not limited to this, but may be, for example, ZIP format or 7z format files.

Further, in the present embodiment, the control unit 301 synchronizes (for example, substantially at the same time) with storing the water quality data file (second archive file including the first archive file) in the storage unit 302, and copies the water quality data file (for example, substantially at the same time). Is transmitted to the server 4 on the cloud via the third communication unit 310 and stored (S307). Before entering this procedure, it is assumed that the access to the server 4 of the application 3a is approved in advance by a predetermined procedure. Further, here, it is assumed that the water quality data file is automatically transmitted to the server 4 in synchronization with the storage of the water quality data file in the storage unit 302, but a predetermined operation in the operation unit 303 by the operator ( For example, it may be performed according to the tapping of a predetermined button). In this case, an arbitrary water quality data file stored in the information device 3 can be transmitted to the server 4 at an arbitrary timing after the fact. Here, when the application 3a transmits the water quality data file from the information device 3 to the server 4, if there is no reply from the server 4 to the information device 3 indicating that the server 4 has received the water quality data file, the transmission is retried. (Retry) may be set to be performed any number of times.

When the water quality data file is saved in the storage unit 302 as described above, for example, the above title is added to the record list screen as shown in G06 of FIG. 9B displayed on the display unit 304. The water quality data displayed on the list screen G06 can be unpacked and viewed with the above-mentioned dedicated application for knowing the private password. If the information device 3 stores the water quality data, the application 3a knows the password, so that the data can be viewed. Further, a viewer information device 5 (FIG. 1) that can access the server 4 and has, for example, an application 5a (FIG. 1) having the same or corresponding browsing function as the application 3a is installed. If 5a knows the private password, the data can be viewed. For example, a case where the water quality data is browsed by the information device 3 that stores the data will be further described as an example. When the control unit 301 outputs a browsing instruction from the operation unit 303 by a predetermined operation of the operator, tapping the title of the specific water quality data of the list screen G06 in this embodiment, the control unit 301 displays the browsing screen G04 shown in FIG. 9B. It is displayed on the display unit 304. The contents of the browsing screen G04 are as described above, and it is possible to edit titles and comments, and add incidental information such as images. Then, when the "save record" button is operated again, the control unit 301 updates the water quality data file and stores it in the storage unit 302. At this time, as described above, the contents of the first archive file included in the second archive file are not changed, and additional incidental information such as the edited title and comment text file or additional images is updated. Will be done.

<Continuous recording>
FIG. 5 is a flowchart showing an outline of a procedure for recording water quality data in the “continuous recording” mode.

When the operation unit 303 outputs a "continuous recording" mode selection instruction by the operation of the operator, the control unit 301 displays a "continuous recording" mode standby screen as shown in G07 of FIG. 9A on the display unit 304. Let me. The flowchart of FIG. 5 shows the procedure after the standby screen G07 is displayed. The control unit 301 sequentially receives the measured value information (pH value and temperature value) and the measured date and time information from the water quality meter 2 via the second communication unit 309 (S401), and the measured value information and the measured date and time information Is sequentially updated and displayed on the standby screen G07 on the display unit 304 (S402). Further, when the standby screen G07 is displayed on the display unit 304, the control unit 301 acquires the current position information from the position information acquisition unit 306 and appropriately updates the position information to the standby screen G07 on the display unit 304. To display. Further, when the standby screen G07 is displayed on the display unit 304, the control unit 301 acquires the peripheral image information currently stored in the finder from the camera 307, and the peripheral image information is standby on the display unit 304. The screen G07 is updated and displayed as appropriate.

Then, when the control unit 301 outputs a continuous recording start instruction from the operation unit 303 by a predetermined operation of the operator, or by tapping the "start continuous recording" button displayed on the standby screen G07 in this embodiment. (S403), the measured value information and the measured date / time information currently displayed on the display unit 304 are recorded together with the current position information in association with each other in the csv file (S405). This csv file is temporarily stored in the storage unit 302. Further, the control unit 301 captures a peripheral image of a still image or a moving image with the camera 307 in synchronization with the execution of this recording, and associates the peripheral image information acquired from the camera 307 with the measured value information or the like into an image file. Record (S404). This image file is temporarily stored in the storage unit 302. In FIG. 5, for convenience, the peripheral image information acquisition process is shown before the measurement value information, the measurement date / time information, and the measurement position information recording process, but in this embodiment, these are performed substantially at the same time. For example, in the case of a still image, it is possible to shoot at substantially the same time by tapping the "start continuous recording" button displayed on the standby screen G07. Further, in the case of a moving image, for example, in response to a tap of the "start continuous recording" button displayed on the standby screen G07, shooting can be started substantially at the same time. Then, as will be described later, in response to the tap of the "end continuous recording" button displayed on the measuring screen as shown in G08 of FIG. 9A, which is displayed on the display unit 304 by the control unit 301 in response to the tap. Shooting can be completed almost at the same time. In the case of a still image, by tapping the "shooting" button displayed on the measurement screen G08, the image is shot multiple times until the "end continuous recording" button is tapped (during continuous recording). be able to.

When the control unit 301 receives the measurement value information and the measurement date / time information from the water quality meter 2 via the second communication unit 309 while displaying the measurement screen G08 on the display unit 304 (S406). , The measured value information and the measurement date / time information are sequentially updated and displayed on the measuring screen G08 on the display unit 304 (S407). Further, the control unit 301 currently displays the current display unit 304 every time the display of the measurement value information and the measurement date / time information is sequentially updated until the "end of continuous recording" button displayed on the measurement screen G08 is tapped. The measured value information and the measured date / time information displayed in the above are additionally recorded in the above csv file together with the current position information (S405 to S407). Then, the control unit 301 outputs a continuous recording end instruction from the operation unit 303 by a predetermined operation of the operator, or by tapping the "end continuous recording" button displayed on the measurement screen G08 in this embodiment. Then, the continuous recording is finished (S408).

In this embodiment, continuous recording can be terminated not only by tapping the "end continuous recording" button but also by the timer function. That is, for example, the time for continuous recording (time from the recording of the first measured value to the recording of the last measured value) on the standby screen G07 or the like can be set in advance. Further, when this timer function is on, the control unit 301 starts continuous recording in S403 and starts measuring the time. Then, in the process corresponding to S408, the control unit 301 can end the continuous recording when the continuous recording time reaches a preset predetermined time. Even when the timer function is on, continuous recording may be terminated at an arbitrary timing by tapping the "end continuous recording" button before the preset predetermined time elapses. The screens G07 and G08 show an example of display when the timer function is turned on. In this way, the control unit 301 continuously measures the measured values during the period (time between predetermined operations or preset time by the timer function) specified according to the command input from the operation unit. Information and incidental information can be associated and recorded.

After that, the control unit 301 displays the measured value information and incidental information (measurement date / time information, measurement position information, peripheral image information) in association with each other in the same manner as in S306 and S307 of FIG. 4 in the "recording current value" mode. Processing (S409), generation and storage of water quality data files (first archive file, second archive file) (S410) are performed. In the "continuous recording" mode, the control unit 301 can display the viewing screen as shown in G09 of FIG. 9B on the display unit 304. On this browsing screen G09, the measured value information is displayed as a graph with respect to the passage of time. Then, for example, when a moving image is being shot during continuous recording, a screen for displaying the measured value and the moving image together as shown in G10 of FIG. 9B is displayed in response to a predetermined operation such as tapping a graph. can do. On this screen G10, changes in the measured values can be displayed according to the reproduction of the moving image (for example, the display showing the measurement date and time in the graph of the measured values moves with the reproduction of the moving image). Further, in the case of the "continuous recording" mode, as shown in G11 of FIG. 9B, the display showing the change of the measured value and the map can be displayed together.

The transmission and recording of the water quality data file to the server 4 and the subsequent viewing and editing of the water quality data file are the same as in the "record current value" mode. Is omitted.

<Intermittent record>
FIG. 6 is a flowchart showing an outline of a procedure for recording water quality data in the “intermittent recording” mode.

When the operation unit 303 outputs an "intermittent recording" mode selection instruction by the operation of the operator, the control unit 301 displays the standby screen of the "intermittent recording" mode as shown in G12 of FIG. 9A on the display unit 304. Let me. The flowchart of FIG. 6 shows a procedure after the standby screen G12 is displayed. The control unit 301 sequentially receives the measured value information (pH value and temperature value) and the measured date and time information from the water quality meter 2 via the second communication unit 309 (S501), and the measured value information and the measured date and time information Is sequentially updated and displayed on the standby screen G12 on the display unit 304 (S502). Further, when the standby screen G12 is displayed on the display unit 304, the control unit 301 acquires the current position information from the position information acquisition unit 306 and appropriately updates the position information to the standby screen G12 on the display unit 304. To display. Further, when the standby screen G12 is displayed on the display unit 304, the control unit 301 acquires the peripheral image information currently stored in the finder from the camera 307, and the peripheral image information is standby on the display unit 304. The screen G12 is updated and displayed as appropriate.

Then, when the control unit 301 outputs an intermittent recording start instruction from the operation unit 303 by a predetermined operation of the operator, or by tapping the "start intermittent recording" button displayed on the standby screen G12 in this embodiment. (S503), the measured value information and the measured date / time information currently displayed on the display unit 304 are recorded together with the current position information in association with each other in the csv file (S504). This csv file is temporarily stored in the storage unit 302. Further, the control unit 301 captures a peripheral image of a still image by the camera 307 in synchronization with the execution of this recording, and records the peripheral image information acquired from the camera 307 in an image file in association with the measured value information and the like. (S505). This image file is temporarily stored in the storage unit 302. In this embodiment, the recording process of the measured value information, the measured date / time information, and the measured position information and the acquisition process of the peripheral image information are performed substantially at the same time. Further, instead of shooting a still image, a moving image may be shot for a predetermined time.

The control unit 301 causes the display unit 304 to display the measuring screen as shown in G13 of FIG. 9A in response to the tapping of the "start intermittent recording" button displayed on the standby screen G12. Further, each time the control unit 301 receives the measurement value information and the measurement date / time information from the water quality meter 2 via the second communication unit 309 while displaying the measurement screen G13 on the display unit 304 ( S506), the measured value information and the measurement date / time information are sequentially updated and displayed on the measuring screen G13 on the display unit 304 (S507). Further, the control unit 301 additionally records the measurement value information and the measurement date / time information currently displayed on the display unit 304 together with the current position information in the csv file at predetermined time presets. In synchronization with each recording (at about the same time in this embodiment), a still image (a moving image over a predetermined time as described above) is taken by the camera 307 and recorded in an image file (S504 to S508). Then, the control unit 301 outputs an intermittent recording end instruction from the operation unit 303 by a predetermined operation of the operator, or by tapping the "end intermittent recording" button displayed on the measurement screen G13 in this embodiment. Then, the intermittent recording is finished (S509). The interval (predetermined time) for recording the measured value information may be changed, for example, on the standby screen G12 or the like.

In the "intermittent recording" mode, as in the case of the "continuous recording" mode described above, the intermittent recording can be terminated not only by tapping the "end intermittent recording" button but also by the timer function. It's okay. That is, for example, the time for intermittent recording (the time from the recording of the first measured value to the recording of the last measured value) on the standby screen G12 or the like can be set in advance. Further, when this timer function is on, the control unit 301 starts intermittent recording and time measurement in S503. Then, in the process corresponding to S509, the control unit 301 can end the intermittent recording when the time for performing the intermittent recording reaches a predetermined time set in advance. Even when the timer function is on, the intermittent recording may be terminated at an arbitrary timing by tapping the "End intermittent recording" button before the preset predetermined time elapses. The screens G12 and G13 show an example of display when the timer function is not used and the operation is terminated by tapping a button. In this way, the control unit 301 intermittently measures the measured value during the period (time between predetermined operations or preset time by the timer function) specified according to the command input from the operation unit. Information and incidental information can be associated and recorded.

After that, the control unit 301 displays the measured value information and incidental information (measurement date / time information, measurement position information, peripheral image information) in association with each other in the same manner as in S306 and S307 of FIG. 4 in the "recording current value" mode. Processing (S510), generation and storage of water quality data files (first archive file, second archive file) (S511) are performed. In the case of the "intermittent recording" mode, the control unit 301 can display the viewing screen as shown in G09 of FIG. 9B on the display unit 304, as in the case of the "continuous recording" mode. On this browsing screen G09, the measured value information is displayed as a graph with respect to the passage of time. Then, for example, when a still image is taken during intermittent recording, the still image taken at substantially the same time as the measured value is taken in response to a predetermined operation such as tapping a graph, as in the screen shown in G10 of FIG. 9B. Images can be displayed together in slide show format or list format. On this screen, changes in measured values can be displayed according to switching of still images in a slide show format or when a specific still image is selected from a list (for example, a display showing the measured date and time in a graph of measured values). Moves, etc.). Further, in the case of the "intermittent recording" mode, as in the case of the "continuous recording", as shown in G11 of FIG. 9B, the display showing the change of the same measured value and the map can be displayed together.

The transmission and recording of the water quality data file to the server 4 and the subsequent viewing and editing of the water quality data file are the same as in the "record current value" mode. Is omitted.

<Log data acquisition>
FIG. 7 is a flowchart showing an outline of a procedure for recording water quality data in the “log data acquisition” mode.

When the water quality data is recorded in the "log data acquisition" mode, the water quality meter 2 needs to have a logging function. In this embodiment, the water quality meter 2 can associate the measured value information with the measurement date / time information generated by the water quality meter clock unit 207 and sequentially store the measured value information in the water quality meter storage unit 204 (logging function). .. In this logging function, typically, the measured value information and the measured date / time information are stored in the water quality meter storage unit 204 at predetermined time intervals. This predetermined time may be changeable. One log data includes at least one set (usually a plurality of sets) of measured values and measurement date / time information recorded continuously. Here, it is assumed that at least one log data in which at least one set of measurement value information and measurement date / time information is associated with each other by this logging function in the water quality meter 2 is stored in the water quality meter storage unit 204 in advance.

When the operation unit 303 outputs a "log data acquisition" mode selection instruction by the operator's operation, the control unit 301 displays the display unit 304 as a standby screen in the "log data acquisition" mode as shown in G14 of FIG. 9A. Is displayed. The flowchart of FIG. 7 shows a procedure after the standby screen G14 is displayed. When displaying the standby screen G14 on the display unit 304, the control unit 301 acquires information on the presence / absence (or how many log data) of the log data in the water quality meter storage unit 204 from the water quality meter 2. The display unit 304 is displayed on the standby screen G14.

Then, the control unit 301 outputs a log data acquisition start instruction from the operation unit 303 by a predetermined operation of the operator, or by tapping the "start log data acquisition" button displayed on the standby screen G14 in this embodiment. Then (S601), acquisition of log data from the water quality meter 2 via the second communication unit 309 is started, and the measured value information and the measured date and time information are associated with each log data and recorded in the csv file. (S602). After that, when the control unit 301 finishes acquiring the log data (S603), the water quality data file (first) is used for each log data in the same manner as in S307 of FIG. 4 in the "recording current value" mode. The process (S604) of generating and saving the archive file (second archive file) is performed. The control unit 301 causes the display unit 304 to display the acquisition screen as shown in G15 of FIG. 9A in response to the tapping of the "start log data acquisition" button displayed on the standby screen G14. Then, the control unit 301 can shift to the process of generating and saving the water quality data file even when the "stop log data acquisition" button displayed on the acquisition screen G15 is tapped.

The water quality data recorded in the "log data acquisition" mode can also be transmitted and recorded to the server 4 and the water quality data file can be viewed and edited after the fact, as in the case of the other modes described above. Since these are the same as in the case of the "record current value" mode, the explanation will be referred to here and duplicate explanations will be omitted.

3. 3. Effect In this embodiment, the water quality meter 2 is equipped with a first communication unit 208 (Bluetooth (registered trademark)) capable of transmitting and receiving information to and from the information device 3. Therefore, the measured value information can be transmitted from the water quality meter 2 to the information device 3. The information device 3 typically referred to as a smartphone or the like is equipped with functions such as GPS and a camera as standard, and can acquire incidental information related to the measured value information by using these functions. In addition, since the association and storage of the measured value information and the incidental information are automated by the application 3a, the work of collecting and managing the measured value information and the incidental information becomes easy, for example, in outdoor water quality measurement. .. In addition, the measurement value information and the incidental information can be aggregated in almost real time by the application 3a, and the result can be confirmed, so that the work load after the fact can be reduced. In addition, the water quality data stored in the information device 3 can be uploaded to a database on the cloud, and information can be shared with other information devices. Therefore, for example, in the measurement in which the measurer performs the measurement at the request of the measurement requester and reports the measurement result to the measurement requester, the work load and the work time for reporting the measurement result can be reduced. In addition, since the water quality data is automatically collected by the application 3a in an archive file that is prevented from being tampered with after the fact, it becomes easy to ensure the truthfulness of the measured values. Further, since incidental information such as measured values and image data is collected in an archive file, it can be easily used for analysis by AI or the like.

In this embodiment, the measured value information and at least a part of the incidental information are stored in the water quality data file so that they cannot be changed, and the subsequent tampering is prevented. On the other hand, it is possible to make changes and then add change history information (for example, the date and time of the last change). This also makes it possible to appropriately prevent falsification after the fact by comparing the measurement date and time information with the change history information.

Further, in this embodiment, the measured value information and at least a part of incidental information (measurement date / time information, measurement position information) are recorded in the csv file, but other arbitrary formats such as XML and SQLite may be used. Further, the layout for displaying the water quality data is not limited to the one illustrated in this embodiment. The application 3a installed on the information device 3 or the application 5a installed on the viewer information device 5 can display water quality data in a desired layout specified by the user by an arbitrary specification method such as XML format. You may be. The display of water quality data is not limited to the display on the screens of the information devices 3 and 5, and may be printed out on paper by a printer communicatively connected to the information devices 3 and 5.

Further, in this embodiment, the case of acquiring position information and image information (still image or moving image) as incidental information has been described, but the recording of these position information and image information (still image or moving image) can be selected to be ON / OFF. May be possible.
