Description

[Technical field]

[0001] The present invention relates to a measurement system, such as a water quality measurement system, which can be used for environmental measurements of rivers, lakes, oceans, wells, groundwater, dams, etc., or for water quality management of industrial wastewater, agricultural water, construction wastewater, fish farm water, and domestic wastewater (for example, water from household septic tanks). [Background technology]

[0002] Conventionally, for example, for environmental measurements of rivers and the like, or for water quality management of factory wastewater and the like, water quality items such as pH, dissolved oxygen (DO), electrical conductivity, salinity, total dissolved solids, seawater specific gravity, temperature, turbidity, oxidation-reduction potential (ORP), chlorophyll, nitrate ions, chloride ions, calcium ions, fluoride ions, potassium ions, ammonium ions, water depth, etc., have been measured using water quality meters as measuring devices. Such measurements are sometimes performed by a person such as a measurement company in response to a request from a measurement client (such as a government agency) who requires the measurement results.

[0003] For example, when measurements are made in the above-mentioned manner, it is necessary to record not only the measured values ​​but also supplementary information (or annotation information) related to the measured values, such as the measurement date and time, the measurement location, and images of the surrounding area of ​​the measurement site, and to associate and manage each measured value with the supplementary information. In particular, in the case of outdoor water quality measurements, the measurement location and images of the surrounding area of ​​the measurement site are important as supplementary information for the purpose of ensuring the authenticity of the measured values ​​or for use in follow-up investigations in the event that a measured value is abnormal.

[0004] Conventionally, a person who performs measurement at the measurement site generally records the measured values ​​obtained by a measurement device together with the measurement date and time in a notebook or the like, and then transcribes the measured values ​​into a prescribed format using a personal computer or the like, and outputs the results to report to the person requesting the measurement. In addition, a person who performs measurement may obtain information on the measurement location and information on images of the surrounding area of ​​the measurement site, and use a personal computer or the like to enter the information into the above-mentioned format and report it to the person requesting the measurement. Conventionally, a separate GPS terminal is generally required to obtain information on the measurement location, and a separate camera is required to obtain images of the surrounding area of ​​the measurement site. In order to associate the measured values ​​with the supplementary information, it is necessary to input each piece of information into a personal computer and consolidate it by entering the data using a keyboard or transferring the data using a memory card, for example.

[0005] Patent Document 1 proposes a management system used for testing the quality of pool water. This management system has a measurement result transmission unit equipped with a portable communication device and a measuring member, and a management server, and stores measurement result information in the storage unit of the management server in association with timing information related to date or time, and also reduces and updates reagent remaining amount information related to the remaining amount of measurement reagent stored in the storage unit of the management server.

[0006] [Patent Document 1] JP 2019-66426 A Summary of the Invention [Problem to be solved by the invention]

[0007] As described above, in the past, for example, in outdoor water quality measurement, the task of aggregating and managing measurement values ​​and incidental information related to the measurement values ​​was cumbersome. In addition, in such measurements, it is important to be able to aggregate the measurement values ​​and incidental information almost in real time at the measurement site and to be able to confirm the results in order to reduce the burden of subsequent work. Furthermore, for example, in measurements in a form in which a measurer performs measurements at the request of a measurement client as described above and reports the measurement results to the measurement client, it is also important to prevent subsequent tampering with the measurement values ​​and incidental information.

[0008] Here, it is possible to provide the measurement device with functions that satisfy the above-mentioned requirements, but this is not desirable because it would require the measurement device to have many functions in addition to its original measurement functions, which would lead to a more complex and larger configuration of the measurement device.

[0009] The management system described in Patent Document 1 cannot solve the above problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The measurement system according to the present invention will now be described in more detail with reference to the drawings.

[0017] [Example 1] 1. Measurement system configuration 1 is a conceptual diagram of a measurement system according to an embodiment of the present invention.

[0023] Furthermore, the water quality meter 2 has a water quality meter clock unit 207, a first communication unit 208, and a water quality meter power supply unit 209. The water quality meter clock unit 207 constitutes a clock information generating unit that generates clock information that is at least one of date and time information (date and time information that is date and time information in this embodiment). The water quality meter clock unit 207 can output date and time information to the water quality meter control unit 203 for managing the measurement date and time, for example. Note that the water quality meter clock unit 207 may be configured as a part of the function of the water quality meter control unit 203. The first communication unit 208 is configured to be capable of transmitting and receiving information (digital information) to and from a second communication unit 309 of the information device 3 described later. The first communication unit 208 is typically configured to be capable of wireless communication with the second communication unit 309 of the information device 3. In this embodiment, the first communication unit 208 is configured to be capable of wireless communication conforming to the Bluetooth (registered trademark) standard. Specifically, the first communication unit 208 can be configured with a circuit (such as a one-chip IC) in which an antenna and a control element are integrally built.

The first communication unit 208 is not limited to a configuration capable of wireless communication, and may be configured to be capable of wired communication via a USB cable or the like. It is sufficient that it corresponds to the second communication unit 309 of the information device 3. The water quality meter power supply unit 209 supplies power for operating each unit of the water quality meter 2. In this embodiment, the water quality meter power supply unit 209 is configured with a battery.

[0024] Although not shown, the water quality meter 2 has a water quality meter control unit 203 and an input / output circuit that controls input and output of signals of various elements. In addition, in Fig. 2, the water quality meter 2 is shown as an integrated configuration incorporating the sensor unit 201 and the measurement unit 202, but for example, as shown in Fig. 1, the sensor unit 201 and at least a part of the measurement unit 202 may be connected via a connector or cable to a water quality meter main body (monitor) provided with a water quality meter operation unit 205 and a water quality meter display unit 206. For example, the sensor unit 201 equipped with a pH electrode, the measurement unit 202 equipped with an amplifier, an A / D converter, a CPU, and the like, and the water quality meter main body 210 equipped with the water quality meter control unit 203, the water quality meter storage unit 204, the water quality meter operation unit 205, the water quality meter display unit 206, the water quality meter clock unit 207, the first communication unit 208, the water quality meter power supply unit 209, and the like may be detachably connected to each other via a connector or cable.

[0025] Thus, in this embodiment, the water quality meter 2 has a built-in or externally connected sensor unit 201 that measures one or more items, such as pH, OPR, dissolved oxygen, electrical conductivity, other ion concentrations, and temperature. In this embodiment, the water quality meter 2 also has a clock function for managing the measurement date and time, and a wireless (Bluetooth (registered trademark, etc.)) or wired (USB cable, etc.) communication function. The water quality meter 2 may also have a logging function, which will be described later.

[0026] Next, the information device 3 will be described. As the information device 3, which is a portable information device (portable communication device, multi-function portable terminal), a so-called smartphone can be suitably used. However, the information device 3 is not limited to this, and a so-called tablet, notebook, or other portable personal computer can also be used. Any portable information device that has all or part of the functions described here and is suitable for implementing the present invention may be used. Smartphones that are capable of running a basic OS such as AndroidOS (registered trademark) or iOS (registered trademark) are widely used. The water quality data management application 3a can be configured to be operable on these basic OSs.

[0027] The information device 3 has a control unit 301 and a storage unit (second storage unit) 302. The control unit 301 is composed of a CPU or the like, which is an arithmetic control means, can execute programs, and generally controls the operation (processing) of the information device 3. In particular, the control unit 301 executes a recording process (management process) of water quality data defined by an application 3a for managing water quality data. The storage unit 302 is composed of a RAM or ROM, which is typically formed of a semiconductor memory, which is a storage means, and can store information (digital information) under the control of the control unit 301.

In particular, in this embodiment, the application 3a for managing water quality data executed by the control unit 301 is stored in the program area 302a of the storage unit 302. The storage unit 302 may be configured to include a device that is fixed to the information device 3, as well as a device that is detachable from the information device 3, such as a memory card.

[0028] The information device 3 also has an operation unit 303 and a display unit 304. The operation unit 303 can input commands to the control unit 301 by an operator's operation, and is composed of mechanical buttons, soft keys on a touch panel displayed on the display unit 304, and the like.

In this embodiment, the display unit 304 is configured to have a touch panel that displays soft keys and also serves at least a part of the functions of the operation unit 303. In this embodiment, the display unit 304 is capable of full-color display. In this embodiment, the operation unit 303 (particularly, the soft keys on the touch panel defined by the basic OS) constitutes a character information input unit for inputting character information.

[0029] The information device 3 also includes a clock unit 305, a position information acquisition unit 306, an image information acquisition unit 307, and an audio information acquisition unit 308. The clock unit 305 constitutes a clock information generation unit that generates clock information that is at least one of date and time information (date and time information that is date and time information in this embodiment). The clock unit 305 can output date and time information to the control unit 301 for managing the measurement date and time, for example. The clock unit 305 may be configured as a part of the function of the control unit 301. The clock information generated by the clock unit 305 may be appropriately corrected based on reference clock information provided, for example, via the Internet, by a process defined by the basic OS. The position information acquisition unit 306 can acquire position information that is information indicating the current position of the information device 3, and output it to the control unit 301. In this embodiment, the position information acquisition unit 306 acquires GPS data as the position information. Specifically, the position information acquisition unit 306 can be configured as a circuit (such as a GPS receiving module) in which an antenna capable of GPS positioning and a control element are integrally built. The position information acquisition unit 306 is not limited to GPS positioning, and may perform positioning using information from a mobile phone base station or a wireless LAN access point, for example. The image information acquisition unit 307 can acquire image information, which is information on still images or videos around the information device 3, and output it to the control unit 301.

The audio information acquisition unit 308 can acquire audio information around the information device 3 and output it to the control unit 301. In this embodiment, the audio information acquisition unit 308 is typically configured as a microphone that converts the operator's voice into an electric signal (digital signal) and outputs it to the control unit 301 (hereinafter, the "audio information acquisition unit" is also simply referred to as the "microphone"). The control unit 301 may be capable of converting voice information acquired by the microphone 308 into text information using a voice recognition function defined by the basic OS.

[0030] Further, the information device 3 has a second communication unit 309, a third communication unit 310, and a power supply unit 311. The second communication unit 309 is configured to be capable of transmitting and receiving information (digital information) to and from the first communication unit 208 of the water quality meter 2 described above. The second communication unit 309 is typically configured to be capable of wireless communication with the first communication unit 208 of the water quality meter 2. In this embodiment, the second communication unit 309 is configured to be capable of wireless communication conforming to the Bluetooth (registered trademark) standard. Specifically, the second communication unit 309 can be configured, for example, as a circuit (such as a one-chip IC) in which an antenna and a control element are integrally incorporated. However, the second communication unit 309 is not limited to this, and may be configured to be capable of infrared communication. In addition, the second communication unit 309 is not limited to a configuration capable of wireless communication, and may be configured to be capable of wired communication via a USB cable or the like. It is sufficient that the second communication unit 309 corresponds to the first communication unit 208 of the water quality meter 2. The third communication unit 310 is for connecting the information device 3 to the computer network 6 (FIG. 1). The computer network 6 may be at least partially or entirely composed of a public communication line, typically the Internet. For example, the third communication unit 310 may be composed of a circuit (such as an IC chip) capable of wireless communication conforming to a wireless communication standard called 4G or 5G. The computer network 6 may be at least partially or entirely composed of a private network such as a LAN. For example, the third communication unit 310 may be composed of a circuit that connects the information device 3 to a LAN by wireless communication conforming to the Wi-Fi (registered trademark) standard or by wired communication. In this case, the information device 3 may be further connected to a public communication line, typically the Internet, via the private network. As described above, when the first communication unit 208 of the water quality meter 2 is configured to communicatively connect the water quality meter 2 to the information device 3 via wireless LAN, the functions of the second communication unit 309 and the third communication unit 310 of the information device 3 can be combined into one (common) communication unit (communication circuit). The power supply unit 311 supplies power for operating each unit of the information device 3. In this embodiment, the power supply unit 311 is configured to include a battery.

[0031] Although not shown, the information device 3 has a control unit 301 and an input / output circuit that controls input and output of signals to and from various elements.

[0032] Thus, in this embodiment, the information device 3 has a display / operation function such as an LCD touch panel, a data storage function in built-in or external storage, a communication function with peripheral devices via wireless (Bluetooth (registered trademark), etc.) or wired (USB cable, etc.) connections, a location information (GPS data) acquisition function, a camera function that can capture videos and still images, an Internet connection function, and a clock function.

[0033] Referring to FIG. 1, the third communication unit 310 of the information device 3 can transmit and receive information to and from a remote server 4 via a computer network 6. The server 4 may be, for example, one directly managed by a provider of the water quality measurement system 1 (for example, a manufacturer of the water quality meter 2). The server 4 may also be one directly managed by a third party that is selectable in the water quality data management application 3a (for example, so-called cloud storage). The server 4 may also be one directly managed by a user (such as a measurement company). For example, when the server 4 is on the Internet, the third communication unit 310 may connect the information device 3 to the server 4 via the Internet. For example, when the server 4 is on a private network such as a wired or wireless LAN, the third communication unit 310 may connect the information device 3 to the server 4 via the LAN. The server 4 may be a general one of any configuration as long as it has all or part of the functions described here and is suitable for embodying the present invention. The server 4 generally includes a transmission / reception unit, a storage unit, a control unit, and the like. The server 4 can be connected to a computer network via a transmitting / receiving unit, can store data in a storage unit, and can control these operations (processing) with a control unit.

[0034] Also, referring to FIG. 1, the viewer information device 5 can communicate with the server 4 via the computer network 6. The viewer information device 5 may be a general device of any configuration, such as a smartphone, a tablet, or a personal computer (which may be either a notebook type or a desktop type), as long as it has all or part of the functions described herein and is suitable for embodying the present invention. The viewer information device 5 is installed with another application 5a (FIG. 1) having substantially the same content as the application 3a for managing water quality data installed in the information device 3, or with another application 5a that mainly implements the function of viewing water quality data among the functions of the application 3a for managing water quality data installed in the information device 3. In other words, the viewer information device 5 may be capable of executing the process of the viewing function of water quality data defined by this other application 5a. The viewer information device 5 generally has an operation unit (input unit), a display unit, a transmission / reception unit, a storage unit, a control unit, and the like. The viewer information device 5 can input information and commands via the operation unit, can display information via the display unit, can be connected to a computer network via the transmission / reception unit, can store the above-mentioned other app 5a and data in the memory unit, and can control these operations (processing) via the control unit.

[0035] 2. Water quality data recording and processing (management processing) Next, the operation (processing) of recording (managing) water quality data by the water quality measurement system 1 of this embodiment will be described with reference to Figs. 3 to 9. Figs. 3 to 7 are flowcharts relating to the recording process of water quality data in this embodiment. Fig. 8 is a schematic diagram for explaining the configuration of water quality data and the structure of a water quality data file (recording file) in this embodiment. Also, Fig. 9 (Figs. 9A and 9B) is a schematic diagram showing an example of a screen displayed on the display unit 304 of the information device 3 by the water quality data management application 3a in this embodiment.

[0036] <Water quality data> FIG. 8(a) is a schematic diagram showing the configuration of water quality data in this embodiment. In this embodiment, the water quality data includes measurement value information and incidental information. The incidental information includes information on the measurement date and time, the measurement position (measurement location), surrounding images (at least one of a still image and a video), a description of the data (text information), and a description of the data (audio information). The measurement date and time information is generated by at least one of the water quality meter clock unit 207 provided in the water quality meter 2 and the clock unit 305 provided in the information device 3. The measurement position information is acquired by the position information acquisition unit 306 provided in the information device 3. The surrounding image information is acquired by the camera 307 provided in the information device 3. The text information (explanation of the data) is input by the operation unit 303 as a text information input unit. The audio information (explanation of the data) is acquired by the microphone 308. The incidental information may also include any other related information (attached file) generated in the information device 3 or acquired by the information device 3 via a computer network or the like (which may be a removable memory). For example, this related information (attached file) may include image information of a still image or a motion acquired by the camera 307 of the information device 3 separately or via a computer network, audio information acquired by the microphone 308 of the information device 3 separately or via a computer network, document information such as a PDF file created by the information device 3 or acquired via a computer network, etc. The incidental information may be some or all of the above examples, but includes at least measurement date and time information.

[0037] <Connection and measurement processing for water quality meters> 3(a) is a flowchart showing an outline of the procedure from connection processing to measurement processing in the water quality meter 2. Note that the procedure described here focuses on the exchange of information between the water quality meter 2 and the information device 3 when the operator starts recording the measurement results on the information device 3 when the water quality meter 2 is in a state where it is possible to measure the pH of the test liquid.

[0038] When a communication start instruction (a connection request standby start instruction) is output from the water quality meter operation unit 205 by the operator, the water quality meter control unit 203 waits for a connection request from the information device 3 via the first communication unit 208 (S101), and when the water quality meter control unit 203 receives the connection request, it responds by connecting the water quality meter 2 and the information device 3 so that they can communicate with each other (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 it is assumed that the water quality meter 2 and the information device 3 are paired in advance according to a predetermined procedure before entering this procedure. Next, the water quality meter control unit 203 receives current date and time information from the information device 3 via the first communication unit 208, and synchronizes the date and time information generated by the water quality meter clock unit 207 with the date and time information generated by the clock unit 305 of the information device 3 (corrects the date and time information generated by the water quality meter clock unit 207) (S103). Note that this synchronization process of the clock information is not essential, and the process may be performed arbitrarily, or may not be provided. Next, the water quality meter control unit 203 obtains measurement value information (pH value and temperature value) according to the output of the sensor unit 201, and obtains measurement date and time information, which is date and time information when the measurement value information was obtained, from the water quality meter clock unit 207 (S104), and transmits the measurement value information and measurement date and time information to the information device 3 via the first communication unit 208 (S105). The processes of S104 and S105 are repeated, for example, at predetermined time intervals until communication between the water quality meter 2 and the information device 3 is terminated (S106). In other words, the water quality meter 2 sequentially transmits the measurement value information and measurement date and time information to the information device 3. The communication end instruction (disconnection request) may be output from the water quality meter operation unit 205 by an operator operating the water quality meter operation unit 205 and input to the water quality meter control unit 203, or may be output from the information device 3 by an operator operating the operation unit 303 of the information device 3 and input to the water quality meter control unit 203 via the first communication unit 208. Also, although the date and time information generated by the water quality meter clock unit 207 provided in the water quality meter 2 is described as being used as the measurement date and time information here, a time stamp based on the date and time information generated by the clock unit 305 provided in the information device 3 may also 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 every time it receives a measurement value from the water quality meter 2 and uses it as the measurement date and time information.

[0039] <Connection and recording processes in information devices> 3(b) is a flowchart showing an outline of the procedure from the connection process in the information device 3 to the recording process of water quality data in the water quality data management application 3a. Note that, before entering this procedure, it is assumed that an instruction to start the water quality data management application 3a is output from the operation unit 303 by an operator, and the control unit 301 starts up this application 3a.

[0040] The control unit 301 transmits a connection request to the water quality meter 2 via the second communication unit 309 in response to the start of the application 3a or a predetermined operation (such as tapping a predetermined button) from the operation unit 303 defined in the application 3a, and connects the information device 3 and the water quality meter 2 so that they can communicate with each other (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 entering this procedure. Next, the control unit 301 transmits current date and time information obtained 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. Also, this clock information synchronization process may be performed by the application 3a for managing water quality data after the application 3a is started, or may be performed by another program such as a basic OS before the application 3a is started. Also, 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 home screen G01 displays the measurement value information and measurement date and time information sequentially transmitted from the water quality meter 2 to the information device 3, while updating it. That is, while the control unit 301 is displaying the home screen G01 on the display unit 304, the control unit 301 sequentially receives the measurement value information (pH value and temperature value) and measurement date and time information from the water quality meter 2 via the second communication unit 309, and sequentially updates and displays the measurement value information and measurement date and time information 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 has the following recording modes: "recording current value", "continuous recording", "intermittent recording", and "log data acquisition". When an instruction to select one of the recording modes is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping one of the "recording mode selection" buttons displayed on the home screen G01, the control unit 301 proceeds to record water quality data in the selected recording mode (S204). The water quality data recording process (management process) in each of the above recording modes in S204 will be described below.

[0041] <Recording current value> FIG. 4 is a flow chart showing an outline of the procedure for recording water quality data in the "record current value" mode.

[0042] When an instruction to select the "record current value" mode is output from the operation unit 303 by the operator, the control unit 301 causes the display unit 304 to display a standby screen of the "record current value" mode as shown in G02 of FIG. 9A. The flowchart of FIG. 4 shows the procedure after the standby screen G02 is displayed. The control unit 301 sequentially receives measurement value information (pH value and temperature value) and measurement date and time information from the water quality meter 2 via the second communication unit 309 (S301), and sequentially updates and displays the measurement value information and measurement date and time information on the standby screen G02 on the display unit 304 (S302). In addition, while the control unit 301 is displaying the standby screen G02 on the display unit 304, it acquires current location information from the location information acquisition unit 306, and appropriately updates and displays the location information on the standby screen G02 on the display unit 304. In addition, when the control unit 301 is causing the display unit 304 to display the standby screen G02, it acquires peripheral image information currently displayed in the viewfinder from the camera 307, and appropriately updates and displays the peripheral image information on the standby screen G02 on the display unit 304.

[0043] Then, when a recording instruction of the current value is output from the operation unit 303 by a predetermined operation of the operator, in this embodiment, by tapping a "record current value" button displayed on the standby screen G02, the control unit 301 records the measurement value information and the measurement date and time information currently displayed on the display unit 304 together with the current position information in a csv file in association with each other (S304). This csv file is temporarily stored in the storage unit 302. In addition, in synchronization with the execution of this recording, the control unit 301 takes a still image or a video of the surroundings by the camera 307, and records the surrounding image information acquired from the camera 307 in an image file in association with the above-mentioned measurement value information, etc. (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 application 5a) (JPEG format for still images and MPEG format for videos can be exemplified). For example, in the case of a still image, shooting can be performed approximately simultaneously with tapping the "record current value" button displayed on the standby screen G02. In the case of a video, shooting can be started approximately simultaneously with tapping the "record current value" button displayed on the standby screen G02. Then, shooting can be ended approximately simultaneously with tapping the "end shooting" button displayed on a screen such as that shown in G03 of FIG. 9A which the control unit 301 causes the display unit 304 to display in response to the tap. Incidentally, storing (saving or recording) measurement value information in association with additional information means that the control unit 301 stores the measurement value information and additional information acquired in association with specific measurement value information. Ta This refers to storing information in a manner that allows it to be identified as incidental information (i.e., storing information in a manner that allows it to be identified as not being incidental information acquired in response to other measurement value information). The specific method of association is not limited to recording in a CSV file and dividing up information groups, and a method such as tagging each piece of information may also be used.

[0044] Next, the control unit 301 causes the display unit 304 to display a viewing screen as shown in G04 of FIG. 9B, which displays the measurement value information and the additional information (measurement date and time information, measurement position information, and surrounding image information) recorded as described above in association with each other (S306). In this embodiment, the viewing screen displays the measurement value information and the additional information (measurement date and time information, measurement position information, and surrounding image information) associated with each other in one screen. The term "aggregated in one screen" includes a case where the entire information can be displayed by changing the display range by scrolling or the like. In addition, the information aggregated in one screen may be partially omitted (for example, thumbnail display or link display of an image), and the entire information may be displayed by performing a predetermined operation such as enlarging or moving to a link destination. In addition, in this embodiment, by tapping the "MAP" button displayed in association with the measurement position information on the viewing screen G04, at least a part of the measurement value information and the additional information (for example, measurement date and time information and measurement position information) can be displayed together with a map, as shown in the screen of G05 of FIG. 9B. The map may be displayed using a function of a program other than the application 3a for managing water quality data, such as the basic OS. Displaying the measurement value information and the additional information in association with each other means displaying the information in such a way that the viewer can identify that the information is additional information acquired in association with specific measurement value information (i.e., displaying the information in such a way that the viewer can identify that the information is not additional information acquired in association with other measurement value information). The specific method of association is not limited to consolidating the information on one screen, and a method of displaying the information on multiple screens that are linked so that the viewer can move between them may be used.

[0045] Here, in the viewing screen G04, the contents of the measurement value information and the measurement date and time information, the measurement position information, and the surrounding image information as the incidental information cannot be changed. Specifically, in this embodiment, the display of the measurement value information, the measurement date and time information, and the measurement position information is not editable. Also, the surrounding image information acquired in synchronization with the recording of the measurement value information as described above cannot be edited or replaced (it may be possible to delete it). On the other hand, the viewing screen G04 is provided with a title input field a, a comment input field b, an incidental information addition button c, and the like. If necessary, the operator can input a title (text information) in the title input field a using the text information input function of the operation unit 303 or the voice recognition function using the microphone 308. Note that, if no title is input, a default title such as the measurement date and time may be attached. Also, if necessary, the operator can input a comment (text information) in the comment input field b using the text information input function of the operation unit 303 or the voice recognition function using the microphone 308. Note that, it may be possible to input a comment using voice information itself. In addition, the operator can take a surrounding image (either a still image or a video) from another angle, for example, by operating the additional information addition button c as necessary. In addition, by operating the additional information addition button c, any of the above-mentioned attachment files (such as a PDF file or a separately acquired image file) can be added in association with the measurement value information. The control unit 301 records the above-mentioned title and comment in a text file (or an audio file if the comment is audio information) in association with the measurement value information as additional information. This text file (or an audio file if the comment is audio 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 they can be handled by the application 3a (and the application 5a). In addition, the control unit 301 temporarily stores the additional additional information such as the above-mentioned additional image information in association with the measurement value information in the storage unit 302.

[0046] Next, when a save instruction is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment by tapping the "Save Record" button displayed on the viewing screen G04, the control unit 301 generates an archive file including the above-mentioned measurement value information and incidental information as a water quality data file and stores it in the storage unit 302 (S307). At this time, in this embodiment, the control unit 301 makes the water quality data file have a two-layer structure 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 measurement value information are compiled into a first archive file for which a private password is set. This password is set in advance in the app 3a by the provider of the water quality measurement system 1, for example, in a state that is private to the user. Note that this password may be updated appropriately by the provider of the water quality measurement system 1, for example, when the app 3a (and app 5a) is updated. The files contained in this first archive file cannot be changed later. Additionally, additional incidental information such as the edited title and comment text files (audio files if the comments are audio information) and additional image information are further compiled into a second archive file together with the first archive file. Since no password is set for this second archive file, it is possible to replace the files contained therein at any time later. The first archive file and the second archive file can be, for example, files in ZIP format or 7z format, but are not limited to these.

[0047] In this embodiment, the control unit 301 transmits a copy of the water quality data file (the second archive file including the first archive file) to the server 4 on the cloud via the third communication unit 310 and stores the file (S307) in synchronization with (for example, substantially simultaneously with) storing the water quality data file in the storage unit 302. It is assumed that the access of the app 3a to the server 4 has been approved in advance by a predetermined procedure before entering this procedure. In addition, although it is assumed here that the water quality data file is automatically transmitted to the server 4 in synchronization with storing the water quality data file in the storage unit 302, it may be transmitted in response to a predetermined operation (for example, tapping a predetermined button) by the operator on the operation unit 303. In this case, any water quality data file stored in the information device 3 can be transmitted to the server 4 at any timing thereafter. Here, the app 3a may be configured to be able to set so that, when the water quality data file is transmitted from the information device 3 to the server 4, if the information device 3 does not receive a reply from the server 4 indicating that the server 4 has received the water quality data file, the app 3a performs a transmission retry any number of times.

[0048] When the water quality data file is saved in the storage unit 302 as described above, the title is added to the list screen of records as shown in G06 of FIG. 9B displayed on the display unit 304. The water quality data displayed on this list screen G06 can be opened and viewed with a dedicated application that knows the above-mentioned private password. If the information device 3 in which the water quality data is saved has the application 3a that knows the password, the data can be viewed. In addition, if the viewer information device 5 (FIG. 1) that can access the server 4 has the application 5a (FIG. 1) installed with the same or corresponding viewing function as the application 3a, and the application 5a knows the above-mentioned private password, the data can be viewed. For example, a case where the water quality data is viewed on the information device 3 in which the water quality data is saved will be further described as an example. When a viewing instruction is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping on the title of a specific water quality data on the list screen G06, the control unit 301 causes the display unit 304 to display the viewing screen G04 shown in FIG. 9B. The contents of this viewing screen G04 are as described above, and it is possible to edit the title and comments, and add additional 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 memory unit 302. At this time, the contents of the first archive file contained in the second archive file as described above are not changed, and the edited title, text files of comments, or additional additional information such as additional images are updated.

[0049] <Continuous Recording> FIG. 5 is a flow chart outlining the procedure for recording water quality data in the "continuous recording" mode.

[0050] When an instruction to select the "continuous recording" mode is output from the operation unit 303 by the operator, the control unit 301 causes the display unit 304 to display a standby screen of the "continuous recording" mode as shown in G07 of FIG. 9A. The flowchart of FIG. 5 shows the procedure after the standby screen G07 is displayed. The control unit 301 sequentially receives measurement value information (pH value and temperature value) and measurement date and time information from the water quality meter 2 via the second communication unit 309 (S401), and sequentially updates and displays the measurement value information and measurement date and time information on the standby screen G07 on the display unit 304 (S402). In addition, while the control unit 301 is displaying the standby screen G07 on the display unit 304, it acquires current location information from the location information acquisition unit 306, and appropriately updates and displays the location information on the standby screen G07 on the display unit 304. In addition, when the control unit 301 is causing the display unit 304 to display the standby screen G07, it acquires peripheral image information currently displayed in the viewfinder from the camera 307, and appropriately updates and displays the peripheral image information on the standby screen G07 on the display unit 304.

[0051] Then, when an instruction to start continuous recording is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping a "Start continuous recording" button displayed on the standby screen G07 (S403), the control unit 301 records the measurement value information and measurement date and time information currently displayed on the display unit 304 together with the current position information in a csv file in association with each other (S405). This csv file is temporarily stored in the storage unit 302. In addition, in synchronization with the execution of this recording, the control unit 301 captures a still or video peripheral image by the camera 307, and records the peripheral image information acquired from the camera 307 in an image file in association with the above-mentioned measurement value information, etc. (S404). This image file is temporarily stored in the storage unit 302. Note that in FIG. 5, for convenience, the acquisition process of the peripheral image information is shown before the recording process of the measurement value information, the measurement date and time information, and the measurement position information, but in this embodiment, these are performed approximately simultaneously. For example, in the case of a still image, the image can be shot almost simultaneously with the tap of the "Start Continuous Recording" button displayed on the standby screen G07. In addition, in the case of a video, the image can be shot almost simultaneously with the tap of the "Start Continuous Recording" button displayed on the standby screen G07. Then, as described later, in response to the tap, the image can be ended almost simultaneously with the tap of the "End Continuous Recording" button displayed on the measurement screen as shown in G08 of FIG. 9A, which the control unit 301 causes the display unit 304 to display. In addition, in the case of a still image, the image can be shot multiple times (during continuous recording) by tapping the "Shoot" button displayed on the measurement screen G08 until the "End Continuous Recording" button is tapped.

[0052] When the control unit 301 is displaying the during-measurement screen G08 on the display unit 304, the control unit 301 sequentially updates and displays the measurement value information and measurement date and time information on the during-measurement screen G08 on the display unit 304 (S407) every time the control unit 301 receives measurement value information and measurement date and time information from the water quality meter 2 via the second communication unit 309 (S406). Furthermore, the control unit 301 additionally records the measurement value information and measurement date and time information currently displayed on the display unit 304 together with the current position information in the csv file every time the display of the measurement value information and measurement date and time information is sequentially updated until the "End Continuous Recording" button displayed on the during-measurement screen G08 is tapped (S405 to S407). Then, when an instruction to end the continuous recording is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping the "End Continuous Recording" button displayed on the during-measurement screen G08, the control unit 301 ends the continuous recording (S408).

[0053] In this embodiment, continuous recording can be ended not only by tapping the "End Continuous Recording" button, but also by a timer function. That is, for example, the time for continuous recording (the time from the recording of the first measurement value to the recording of the last measurement value) can be set in advance on the standby screen G07 or the like. Furthermore, when this timer function is on, the control unit 301 starts the continuous recording in S403 and starts measuring time. Then, in the process corresponding to S408, the control unit 301 can end the continuous recording when the time for which continuous recording has been performed reaches a predetermined time set in advance. Even when the timer function is on, the continuous recording may be ended at any timing by tapping the "End Continuous Recording" button before the predetermined time has elapsed. Screens G07 and G08 show examples of displays when the timer function is on. In this way, the control unit 301 can continuously record measurement value information and incidental information in association with each other during a period (a time between predetermined operations or a time set in advance by the timer function) specified according to a command input from the operation unit.

[0054] Thereafter, the control unit 301 performs a process of displaying the measurement value information in association with the auxiliary information (measurement date and time information, measurement location information, surrounding image information) (S409) and a process of generating and saving water quality data files (first archive file, second archive file) (S410) in the same manner as S306 and S307 in FIG. 4 in the "recording of current value" mode. In the "continuous recording" mode, the control unit 301 can display a viewing screen as shown in G09 in FIG. 9B on the display unit 304. In this viewing screen G09, the measurement value information is displayed as a graph against the passage of time. Then, for example, when a video is taken during continuous recording, a screen that displays the measurement value and the video together as shown in G10 in FIG. 9B can be displayed in response to a predetermined operation such as tapping the graph. In this screen G10, the change in the measurement value can be displayed in accordance with the playback of the video (for example, the display indicating the measurement date and time in the graph of the measurement value moves in accordance with the playback of the video). In the case of the "continuous recording" mode, as shown in G11 of FIG. 9B, a display showing the change in the measured value similar to the above can also be displayed together with a map.

[0055] The transmission and recording of water quality data files to the server 4, and subsequent viewing and editing of water quality data files are the same as in the ``Recording Current Values'' mode, so we will refer to those explanations here and omit redundant explanations.

[0056] <Intermittent recording> FIG. 6 is a flow chart showing an outline of the procedure for recording water quality data in the "intermittent recording" mode.

[0057] When an instruction to select the "intermittent recording" mode is output from the operation unit 303 by the operator, the control unit 301 causes the display unit 304 to display a standby screen for the "intermittent recording" mode as shown in G12 of FIG. 9A. The flowchart in FIG. 6 shows the procedure after the standby screen G12 is displayed. The control unit 301 sequentially receives measurement value information (pH value and temperature value) and measurement date and time information from the water quality meter 2 via the second communication unit 309 (S501), and sequentially updates and displays the measurement value information and measurement date and time information on the standby screen G12 on the display unit 304 (S502). In addition, while the control unit 301 is displaying the standby screen G12 on the display unit 304, it acquires current location information from the location information acquisition unit 306, and appropriately updates and displays the location information on the standby screen G12 on the display unit 304. In addition, when the control unit 301 is causing the display unit 304 to display the standby screen G12, it acquires peripheral image information currently displayed in the viewfinder from the camera 307, and appropriately updates and displays the peripheral image information on the standby screen G12 on the display unit 304.

[0058] Then, when an instruction to start intermittent recording is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping the "Start Intermittent Recording" button displayed on the standby screen G12 (S503), the control unit 301 records the measurement value information and measurement date and time information currently displayed on the display unit 304 together with the current position information in a csv file in association with each other (S504). This csv file is temporarily stored in the storage unit 302. In addition, in synchronization with the execution of this recording, the control unit 301 captures an image of the surroundings of the still image by the camera 307, and records the surrounding image information acquired from the camera 307 in an image file in association with the above measurement value information, etc. (S505). This image file is temporarily stored in the storage unit 302. In this embodiment, the recording process of the measurement value information, measurement date and time information, and measurement position information and the acquisition process of the surrounding image information are performed approximately simultaneously. In addition, instead of capturing a still image, a video may be captured for a predetermined time.

[0059] In response to tapping of the "Start Intermittent Recording" button displayed on the standby screen G12, the control unit 301 causes the display unit 304 to display a measurement-in-progress screen as shown in G13 of FIG. 9A. In addition, while the control unit 301 is displaying the measurement-in-progress screen G13 on the display unit 304, the control unit 301 sequentially updates and displays the measurement value information and measurement date and time information on the measurement-in-progress screen G13 on the display unit 304 (S507) every time the control unit 301 receives measurement value information and measurement date and time information from the water quality meter 2 via the second communication unit 309 (S506). In addition, the control unit 301 additionally records the measurement value information and measurement date and time information currently displayed on the display unit 304 together with the current position information in the csv file at every predetermined time set in advance, and also records a still image (which may be a video over a predetermined time period as described above) by the camera 307 in synchronization with each recording (almost simultaneously in this embodiment) and records it in an image file (S504 to S508). Then, when an instruction to end intermittent recording is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping an "End Intermittent Recording" button displayed on the measurement in progress screen G13, the control unit 301 ends the intermittent recording (S509). Note that the interval (predetermined time) for recording the measurement value information may be changeable, for example, on the standby screen G12.

[0060] In the "intermittent recording" mode, as in the case of the "continuous recording" mode described above, the intermittent recording may be terminated not only by tapping the "end intermittent recording" button but also by a timer function. That is, for example, the time for performing the intermittent recording (the time from the recording of the first measurement value to the recording of the last measurement value) can be set in advance on the standby screen G12 or the like. Furthermore, when this timer function is on, the control unit 301 starts the intermittent recording in S503 and starts measuring the time. Then, in the process corresponding to S509, the control unit 301 can end the intermittent recording when the time during which the intermittent recording has been performed reaches a predetermined time. Even when the timer function is on, the intermittent recording may be terminated at any timing by tapping the "end intermittent recording" button before the predetermined time has elapsed. Screens G12 and G13 show examples of displays when the recording is terminated by tapping a button without using the timer function. In this way, the control unit 301 can intermittently associate and record the measurement value information and the auxiliary information during a period (the time between predetermined operations or a pre-set time using a timer function) specified in response to an instruction input from the operation unit.

[0061] Thereafter, the control unit 301 performs a process of displaying the measurement value information in association with the auxiliary information (measurement date and time information, measurement position information, surrounding image information) (S510) and a process of generating and saving the water quality data file (first archive file, second archive file) (S511) in the same manner as S306 and S307 in FIG. 4 in the "recording of current value" mode. In the "intermittent recording" mode, the control unit 301 can display a viewing screen as shown in G09 in FIG. 9B on the display unit 304, as in the "continuous recording" mode. In this viewing screen G09, the measurement value information is displayed as a graph against the passage of time. Then, for example, if a still image is taken during intermittent recording, the measurement value and the still image taken at approximately the same time can be displayed together in a slideshow format or a list format, as in the screen shown in G10 in FIG. 9B, in response to a predetermined operation such as tapping on the graph. On this screen, the change in the measurement value can be displayed in accordance with switching of still images in a slideshow format or selecting a specific still image from a list (for example, the display showing the measurement date and time in a measurement value graph can be moved). In addition, in the case of "intermittent recording" mode, as in the case of "continuous recording", it is also possible to display the display showing the change in the measurement value similar to that described above together with a map, as shown in G11 in Fig. 9B.

[0062] The transmission and recording of water quality data files to the server 4, and subsequent viewing and editing of water quality data files are the same as in the ``Recording Current Values'' mode, so we will refer to those explanations here and omit redundant explanations.

[0063] <Log data acquisition> FIG. 7 is a flow chart showing an outline of the procedure for recording water quality data in the "log data acquisition" mode.

[0064] When performing the recording process of water quality data 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 is capable of associating measurement value information with measurement date and time information generated by the water quality meter clock unit 207 and sequentially storing the information in the water quality meter storage unit 204 (logging function). Typically, this logging function stores the measurement value information and the measurement date and time information in the water quality meter storage unit 204 at predetermined intervals. This predetermined time may be changeable. One piece of log data includes at least one set (usually multiple sets) of measurement values ​​and measurement date and time information that are continuously recorded. Here, it is assumed that at least one piece of log data, in which at least one set of measurement value information and measurement date and time information are 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.

[0065] When an instruction to select the "log data acquisition" mode is output from the operation unit 303 by an operator, the control unit 301 causes the display unit 304 to display a standby screen for the "log data acquisition" mode as shown in G14 of Fig. 9A. The flowchart in Fig. 7 shows the procedure after this standby screen G14 is displayed. When the control unit 301 causes the display unit 304 to display the standby screen G14, it obtains information from the water quality meter 2 as to whether or not there is log data in the water quality meter memory unit 204 (or how many pieces of log data there are), and causes the display unit 304 to display the standby screen G14.

[0066] Then, when an instruction to start log data acquisition is output from the operation unit 303 by a predetermined operation by the operator, in this embodiment, by tapping the "Start log data acquisition" button displayed on the standby screen G14 (S601), the control unit 301 starts acquiring log data from the water quality meter 2 via the second communication unit 309, and records the measurement value information and the measurement date and time information for each piece of log data in a csv file in association with each other (S602). After that, when the control unit 301 finishes acquiring the log data (S603), it performs a process of generating and saving a water quality data file (first archive file, second archive file) for each piece of log data (S604) in the same manner as S307 in FIG. 4 in the "record current value" mode. Note that, in response to tapping the "Start log data acquisition" button displayed on the standby screen G14, the control unit 301 causes the display unit 304 to display an acquisition in progress screen as shown in G15 in FIG. 9A. Furthermore, when the “Stop log data acquisition” button displayed on the acquisition screen G15 is tapped, the control unit 301 can transition to the process of generating and saving a water quality data file.

[0067] As with the other modes mentioned above, water quality data recorded in the "log data acquisition" mode can also be sent to the server 4, recorded, and the water quality data file can be viewed or edited afterwards. These are the same as in the "current value recording" mode, so the explanation therefor will be used here and will not be repeated.

[0068] 3.Effects In this embodiment, the water quality meter 2 is equipped with a first communication unit 208 (Bluetooth (registered trademark)) that enables information transmission and reception between the water quality meter 2 and the information device 3. Therefore, the water quality meter 2 can transmit measurement value information to the information device 3. The information device 3, which is typically a smartphone, is equipped with functions such as a GPS and a camera as standard, and these can be used to obtain additional information related to the measurement value information. In addition, the association and storage of the measurement value information and the additional information is automated by the application 3a, which simplifies the task of aggregating and managing the measurement value information and the additional information, for example, in outdoor water quality measurement. In addition, the measurement value information and the additional information can be aggregated almost in real time by the application 3a, and the results can be confirmed, so that the subsequent work burden 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 the information can be shared with other information devices. Therefore, for example, in a measurement in a form in which a measurer performs a measurement at the request of a measurement requester and reports the measurement results to the measurement requester, the work burden and work time for reporting the measurement results can be reduced. In addition, the water quality data is automatically compiled by the app 3a into an archive file that prevents subsequent tampering, making it easy to guarantee the authenticity of the measured values. Furthermore, because the measured values, image data, and other supplementary information are compiled into an archive file, it can be easily provided for analysis by AI, etc.

[0069] In this embodiment, the measurement value information and at least a part of the associated information cannot be changed. To The data is stored in the water quality data file as a record to prevent subsequent falsification. However, it is possible to allow changes and add change history information (such as the last change date and time). This also makes it possible to appropriately prevent subsequent falsification by comparing the measurement date and time information with the change history information.

[0070] In this embodiment, the measurement value information and at least a part of the additional information (measurement date and time information, measurement location information) are recorded in a CSV file, but any other format such as XML or SQLite may be used. The layout for displaying the water quality data is not limited to that exemplified in this embodiment. The application 3a installed in the information device 3 or the application 5a installed in the viewer information device 5 may be capable of displaying the water quality data in a desired layout designated by the user using any designation method such as XML format. The display of the water quality data is not limited to display on the screen of the information device 3, 5, but may be capable of printing out the data on paper using a printer connected to the information device 3, 5 so as to be able to communicate with the information device.

[0071] In addition, in this embodiment, the case where location information and image information (still images and videos) are obtained as supplementary information has been described, but the recording of this location information and image information (still images and videos) may be selectable ON / OFF.

[0072] [Other Examples] Although the present invention has been described above with reference to specific embodiments, the present invention is not limited to the above-mentioned embodiments.

[0073] In the above-mentioned embodiment, the measurement system is embodied as a water quality measurement system, but the measurement target is not limited to water quality. In particular, the measurement system can be used as a measurement system for measurement targets that need to be measured outdoors, such as temperature, humidity, air pressure, wind speed, wind direction, illuminance, ultraviolet light amount, water pressure, water depth, flow rate, radiation amount, soil properties (moisture content, pH, various ion concentrations, etc.), various gas concentrations, particulate matter, seismic intensity, magnetic flux density, and electric field strength, and the same effects as those of the above-mentioned embodiment can be obtained. When configuring a measurement system for these other measurement targets, the measurement device only needs to have a sensor unit corresponding to the measurement target exemplified above, instead of the sensor unit in the above-mentioned embodiment.
