  The processing unit 25 generally controls the gateway 2. Specifically, the processing unit 25 is an example of a “first processing unit”, and when the measurement value data Dm transmitted from the measuring device 1 via the LAN 11 is received by the communication unit 21, The measured value data Dm is stored in the storage unit 26 (an example of a process of “acquiring measured value data from a measuring device”).

  Further, as will be described later, the processing unit 25 transmits imaging condition data D3 (an example of “generation condition data”) transmitted from the data server 4 via the Internet 13 and the mobile communication network 12 and received by the communication unit 22. Accordingly, the camera 3 is controlled to execute “imaging processing” described later, and the imaging data Dp (an example of “state specifying data”) output from the camera 3 is stored in the storage unit 26 (“state from the data generation device” This is an example of a process of “acquiring specific data” and an example of a “second control process”).

  Further, the processing unit 25 associates the acquired measurement value data Dm and the imaging data Dp with each other in accordance with preset conditions, and transmits them from the communication unit 22 to the data server 4 via the mobile communication network 12 and the Internet 13.

Dp and the like are stored.

  The camera 3 is an example of an “imaging device” as a “data generation device”, and in the measurement system 100 of the present example, as an example, the camera 3 is connected to the gateway 2 via a communication cable. Example of a configuration in which the “device” is a “data transmission device”). The camera 3 executes “imaging processing” as “data generation processing” under the control of the gateway 2 to image the measurement target X and / or the measuring instrument 1 and performs imaging data Dp (execution of the measurement processing). “State specifying data” (image data of a still image as an example) that can specify the state of at least one of the measuring device and the measurement target whose measured amount is measured by the measuring device is output to the gateway 2.

  The data server 4 is an example of a “data recording device” and includes a recording unit 31, a communication unit 32, an operation unit 33, a display unit 34, a processing unit 35, and a storage unit 36 as shown in FIG. The measurement value data Dm and the imaging data Dp transmitted from the gateway 2 via the body communication network 12 and the Internet 13 are recorded, and any information processing terminal (for example, an operation terminal T described later) or the like is recorded via the Internet 13. The measurement value data Dm and the imaging data Dp can be transmitted.

  The recording unit 31 transmits condition setting screen data D0 (an example of “condition setting data”) to be transmitted to the operation terminal T and the like as will be described later, response data D1 transmitted from the operation terminal T and the like as will be described later, As will be described later, a large-capacity recording medium capable of recording measurement condition data D2, imaging condition data D3 and notification condition data D4 generated by the processing unit 35, measurement value data Dm, imaging data Dp, and the like transmitted from the gateway 2 (Hard disk drive etc.).

  The communication unit 32 is composed of a communication unit that can be connected to the Internet 13, and under the control of the processing unit 35, transmission processing of condition setting screen data D0, measurement condition data D2, imaging condition data D3, and a notification mail Dr described later, In addition, reception processing of response data D1, measurement value data Dm, and imaging data Dp is executed. The operation unit 33 includes a keyboard and a pointing device (not shown) that can execute an operation condition setting operation (operation by a server administrator) of the data server 4. The display unit 34 displays various information indicating the operation state of the data server 4.

  The processing unit 35 controls the data server 4 as a whole. Specifically, the processing unit 35 functions as a “second processing unit” and sets condition setting screen data D0 for setting “imaging conditions” for causing the camera 3 to execute “imaging processing”. A transmission process (an example of a “third transmission process”) that is transmitted from the communication unit 32 to “arbitrary resource” connected to the Internet 13 is executed. In this case, in this example, an operation terminal T (a “communication terminal equipped with a browser such as a personal computer, a tablet, and a smartphone”) connectable to the Internet 13 is used as “arbitrary resource”.

  In addition, the processing unit 35 receives response data D1 transmitted from the operation terminal T in response to an operation on the operation terminal T in a state where the screen of the condition setting screen data D0 is displayed, as will be described later. Sometimes, a transmission process (an example of “second transmission process”) is performed in which imaging condition data D3 and the like are generated according to the content of the response data D1 and transmitted to the gateway 2. The specific contents of the process for generating the imaging condition data D3 and the like based on the response data D1 will be described in detail later.

  Further, the processing unit 35 functions as a “fourth processing unit”, and when the measurement value data Dm satisfying the “preset condition” is transmitted from the gateway 2, the processing unit 35 is based on the measurement value data Dm. The notification mail Dr including the generated graph or the like (an example of “measurement result notification data”) and the imaging data Dp associated with the measurement value data Dm is designated as “pre-specified notification target (pre-set email address”). : Mail server) ”(exemplary“ notification process ”which is an example of“ fourth transmission process ”) is transmitted (“ measurement value data and measurement result notification data ”). “At least one of“ is an example of “measurement result notification data”). The specific contents of the above-mentioned “preset conditions” and the notification mail Dr based on the measured value data Dm will be described later.

  The storage unit 36 temporarily stores the calculation result of the processing unit 35 and various data transmitted / received via the communication unit 32.

  Next, an example of a usage pattern of the measurement system 100 will be described.

  When using the measurement system 100, a gateway 2 (gateway 2) that permits user registration (issue of an authentication ID and password) of a person who has authority to use the data server 4 and connection to the mobile communication network 12 In order to facilitate understanding of the configuration of the “data transmission device” and the “measurement system”, explanations regarding these registration operations and authentication processing based on the registration results will be given. Omitted.

  First, the measuring instrument 1, the gateway 2, and the camera 3 are installed in the measurement site where the measurement object X exists. Specifically, the measuring sensor 1 of each measuring instrument 1 is attached to the measuring object X, and each measuring instrument 1 is connected via a network cable constituting the LAN 11 (via a switching hub as necessary). Connect to the communication unit 21 of the gateway 2. Further, the camera 3 is set so that at least one of the measurement target X and the measuring instrument 1 (imaging target that can capture imaging data Dp that can identify the cause when abnormal measurement value data Dm is output) can be captured. To connect to the gateway 2. Thus, the preparation work at the measurement site is completed.

  The “measurement condition” by each measuring instrument 1 may be performed individually for each measuring instrument 1 before each measuring instrument 1 is installed at the measurement site or as one work item of the installation work. However, in this example, the measurement condition data D2 transmitted from the data server 4 to the gateway 2 together with the imaging condition data D3 for the “imaging condition” by the camera 3 is transferred from the gateway 2 to the measurement instrument 1. It is assumed that “measurement conditions” are set in FIG. Specifically, as an example, first, a browser of the operation terminal T is started to set a predetermined address of the data server 4 (setting operation conditions of the mobile communication network 12 and the measuring device 1, measurement value data Dm, imaging data, etc. The address for downloading Dp is accessed via the Internet 13.

  In response to this, the processing unit 35 of the data server 4 reads out the condition setting screen data D0 for displaying the operation condition setting screen on the display screen (browser) of the operation terminal T from the recording unit 31 and transmits it from the communication unit 32 to the Internet. 13 to the operation terminal T (an example of “third transmission process”). Thereby, the “measurement condition” of “measurement process” by the measuring instrument 1, the “imaging condition” of “imaging process” by the camera 3, and the “notification” by the data server 4 (processing unit 35) are displayed on the display screen of the operation terminal T. A condition setting screen for setting “notification condition (execution condition of“ fourth transmission process ”)” of “processing” and the like is displayed (not shown).

  In this case, with respect to the “measurement condition”, as an example, setting items such as a measurement start time, a measurement cycle, and a measurement end time are input (or displayed) in the target setting item column in the display screen of the operation terminal T. Response data D1 that can specify the input (selected) condition is transmitted from the operation terminal T to the data server 4 via the Internet 13.

  For “imaging condition”, for example, the condition “execute imaging process every time measurement value data Dm is transmitted from the gateway 2” is input to the target setting item field in the display screen of the operation terminal T. The response data D1 that can specify the input (selected) condition by selecting (or selecting such a condition candidate from the displayed selection candidate group) is sent from the operation terminal T via the Internet 13 to the data server 4 Sent to.

  Furthermore, regarding the “notification condition”, as an example, when measured value data Dm that satisfies the condition “exceeding the specified value (or falling below the specified value)” (an example of “preset condition”) is transmitted. And the “specified value” are input to the target setting item field in the display screen of the operation terminal T (or such a condition candidate is selected from the displayed selection candidate group). The response data D1 that can specify the (selected) conditions and specified values is transmitted from the operation terminal T to the data server 4 via the Internet 13.

  In the data server 4, the processing unit 35 receives the measurement condition data D <b> 2 to be transmitted to the measuring instrument 1 via the gateway 2 based on the response data D <b> 1 received by the communication unit 32, and the imaging to be transmitted to the gateway 2. The condition data D3 and notification condition data D4 required for “notification process (fourth transmission process)” to be executed later are generated and recorded in the recording unit 31. Further, the processing unit 35 sets the content of the notification condition data D4 as an execution condition (notification condition) of the “notification process”. Thereby, preparations for executing the “notification process” by the data server 4 are completed. Furthermore, the processing unit 35 transmits the measurement condition data D2 and the imaging condition data D3 from the communication unit 32 to the gateway 2 (an example of “second transmission process”).

  In the gateway 2, the processing unit 25 stores the measurement condition data D2 and the imaging condition data D3 transmitted from the data server 4 via the Internet 13 and the mobile communication network 12 and received by the mobile communication network 12. 26 is stored. Further, the processing unit 25 sets the content of the imaging condition data D3 as an execution condition (control condition: imaging condition) of a control process (“second control process”) that causes the camera 3 to execute “imaging process”. Thus, preparation for executing “imaging processing” in which the camera 3 images the imaging target (the measurement target X or the measuring device 1) under the control of the gateway 2 (preparation for the gateway 2 to control the camera 3) is completed.

  Further, the processing unit 25 transmits the measurement condition data D2 from the communication unit 21 to the measuring instrument 1. At this time, when the measuring instrument 1 receives the measurement condition data D2 transmitted from the gateway 2 via the LAN 11, the measuring instrument 1 sets a “measurement condition” for executing “measurement processing” according to the measurement condition data D2. To do. As a result, preparation for executing the “measurement process” for the measurement object X by the measuring instrument 1 is completed. Thus, a series of preparation work using the measurement system 100 is completed.

  On the other hand, when the “measurement start time” of the “measurement condition” set based on the measurement condition data D2 as described above has arrived, the measuring instrument 1 executes “measurement processing” to determine the measurement target X. A measurement value defined in advance is measured to generate measurement value data Dm, and the generated measurement value data Dm is transmitted to the gateway 2. In the gateway 2, when the measurement value data Dm transmitted from the measuring device 1 via the LAN 11 is received by the communication unit 21 (an example of processing of “acquiring measured value data from the measuring device”). The processing unit 25 stores the measurement value data Dm in the storage unit 26 and determines that the “imaging timing” of the “control condition (imaging condition)” set based on the imaging condition data D3 has arrived. To perform “imaging process” (an example of “second control process”).

  In response to this, the camera 3 executes “imaging processing” for imaging the imaging target (the measurement target X or the measuring device 1) to generate imaging data Dp, and outputs the generated imaging data Dp to the gateway 2. As a result, the camera 3 outputs imaging data Dp having a time stamp almost the same time as the generation time of the measurement value data Dm generated by the measuring instrument 1 and transmitted to the gateway 2 (time stamp of the file of the measurement value data Dm). Is done. In addition, when the imaging data Dp is output from the camera 3 (an example of a process of “obtaining state specifying data from the data generation device”), the processing unit 25 mutually transmits the measurement value data Dm and the imaging data Dp. The data is transmitted from the communication unit 22 to the data server 4 in association (an example of “first transmission process”).

  In this case, with respect to the “association” between the measurement value data Dm and the imaging data Dp, as an example, a measuring device that outputs the measurement value data Dm to a part of the file name of the measurement value data Dm and the file name of the imaging data Dp. 1 includes a character string of unique identification information, includes a file name of the corresponding imaging data Dp as a part of header information of the measurement value data Dm, and corresponds as a part of header information of the imaging data Dp. The file name of the measured value data Dm to be included is included. In this example, it is assumed that the data Dm and Dp are “associated” by including the character string of the identification information in part of the file names of the data Dm and Dp.

  In the data server 4, when the measured value data Dm and the imaging data Dp transmitted from the gateway 2 via the mobile communication network 12 and the Internet 13 are received by the communication unit 32, the processing unit 35 Dm and Dp are recorded in the recording unit 31. Further, the processing unit 35 determines whether or not the recorded measurement value data Dm is a value that satisfies the set “notification condition”. At this time, when the condition “when the measured value data Dm exceeding the specified value is transmitted” and the “specified value” are set as the “notification condition”, the processing unit 35 sets the measured value data When the value of Dm is equal to or less than the specified value, it is determined that the “notification condition” is not satisfied, and the process at the time of receiving both data Dm and Dp is completed without executing the “notification process”.

  Thereafter, whenever the timing according to the “measurement period” in the “measurement condition” comes, execution of “measurement processing” by the measuring instrument 1 (transmission of measured value data Dm to the gateway 2), and by the gateway 2 Control of camera 3 and execution of “imaging process” by camera 3 (execution of “second control process” and output of imaging data Dp from camera 3) and association and data of both data Dm and Dp by gateway 2 The transmission to the server 4 (execution of “first transmission process”) and the reception process of both data Dm and Dp by the data server 4 and the recording process to the recording unit 31 are “measurement end time” in “measurement conditions”. It is executed repeatedly until.

  In this case, in the measurement system 100 of this example, the recordable area of the recording unit 31 in the data server 4 is excessively reduced by recording a large number of imaging data Dp (the recordable capacity for recording new measurement value data Dm is small). As an example, the number of imaging data Dp that can be recorded in the recording unit 31 (capacity in which the imaging data Dp can be recorded) is determined for each measuring instrument 1 (or as an example). When a plurality of gateways 2 are used in combination, each gateway 2 can be set in advance. Moreover, in the state in which such a setting is made, as an example, the set number (set capacity) is set except for the imaging data Dp transmitted together with the measurement value data Dm that satisfies the “notification condition” as described later. When new imaging data Dp is transmitted after reaching the destination, new imaging data Dp can be recorded by deleting the earliest imaging data Dp among the imaging data Dp recorded in the recording unit 31. And

  In the measurement system 100 of this example, when the value of the measurement value data Dm transmitted from the gateway 2 to the data server 4 is a value satisfying the “notification condition” as described above, the “notification process” is performed in the data server 4. Is executed. Specifically, when the measurement value data Dm having a value exceeding the set “specified value” is transmitted from the gateway 2, the processing unit 35 satisfies the “notification condition”. The “notification process” is started.

  In the “notification process”, the processing unit 35 first, as an example, based on the measured value data Dm exceeding the “specified value” and the measured value data Dm measured by the same measuring instrument 1 before the measured value data Dm. Then, a graph (an example of “measurement result notification data”) showing a change in the amount to be measured for the measurement target X is generated. Next, the processing unit 35 generates the generated graph, the image of the imaging data Dp transmitted together with the measured value data Dm exceeding “specified value”, and a predetermined message (for example, “measured value exceeding specified value”). Is generated from the recording unit 31 for the preset notification target (preset mail address: mail server) ”. 13 (an example of “fourth transmission process”).

  Thereby, the person who has received the notification mail Dr transmitted from the data server 4 recognizes that the measured value has changed to a state exceeding the specified value based on the message and the graph in the notification mail Dr, and is attached. The state of the measurement site is specified based on the existing image (the measurement target X captured by the camera 3 or the image of the measuring device 1).

  Specifically, for example, when an “indicator indicating abnormal operation” is provided on the measurement target X, whether or not the indicator is in a lighting state is specified based on the image, and the display of the measuring instrument 1 When the measured value is displayed on the part, it is specified based on the image whether or not the displayed measured value exceeds the specified value. Further, the user operates the operation terminal T or the like as necessary to access the data server 4, and downloads and measures the measurement value data Dm (and corresponding imaging data Dp) recorded in the recording unit 31. The measurement result of the target X is analyzed in detail, or the measurement site X and the operating state of the measuring device 1 are confirmed by visiting the measurement site.

  Although different from the above example, instead of the graph generated based on the measurement value data Dm (or in addition to such a graph), the measurement value data Dm itself and the image of the imaging data Dp are notified to the notification mail Dr. It is also possible to employ a configuration in which the data server 4 is attached to the data and transmitted. Even when such a configuration is adopted, the person who has received the notification mail Dr recognizes that the measurement value has changed to a state exceeding the specified value based on the message in the notification mail Dr and the measurement value data Dm. Based on the attached image (the measurement object X imaged by the camera 3 or the image of the measuring device 1), the state of the measurement site can be specified.

  In addition, although different from the above-described operation mode, an operation mode in which the “notification process” by the data server 4 is not executed can be adopted. Even when the measurement system 100 is used in such an operation mode, the user accesses the data server 4 by operating the operation terminal T or the like at an arbitrary timing, and the measurement value data Dm recorded in the recording unit 31. And by downloading the imaging data Dp, the measurement value data Dm is analyzed to determine whether it is within the normal value range, or the measurement target X and the operating state of the measuring instrument 1 are referred to by referring to the image of the imaging data Dp Or can be identified as normal.

  As described above, the gateway 2 acquires the measurement value data Dm from the measuring instrument 1 and transmits the acquired measurement value data Dm to the data server 4 via the mobile communication network 12 and the Internet 13. 1 ”, the processing unit 25 acquires imaging data Dp that can specify at least one of the state of the measuring instrument 1 and the measurement target X from the camera 3 and the measured value data Dm acquired from the measuring instrument 1. And the imaging data Dp acquired from the camera 3 are associated with each other and transmitted to the data server 4. In addition, the measurement system 100 includes the measuring instrument 1, the gateway 2, and the data server 4.

  Therefore, according to the gateway 2 and the measurement system 100, by acquiring the measurement value data Dm and the imaging data Dp recorded in the data server 4, it is difficult to specify the measurement site by analyzing the measurement value data Dm alone. Can be easily identified based on the imaging data Dp, so that even a person unfamiliar with the use of this type of apparatus or system can execute the “measurement process in which the acquired measurement value data Dm has been executed normally. It is possible to reliably and easily specify whether or not the result is "."

  Further, in the gateway 2, the processing unit 25 “image data” obtained by capturing an image of at least one of the measurement object X and the measuring instrument 1 by the “imaging device” as the “data generation device” in the “first transmission process”. And at least one of “recording data” in which the “recording device” as the “data generating device” has recorded the sound at the installation location of the measuring instrument 1 (in this example, the camera 3 as the “imaging device” is measured X And imaging data Dp) obtained by imaging at least one of the measuring instruments 1 is acquired as “state specifying data”. Therefore, according to the gateway 2 and the measurement system 100, the state of the measurement target X and the measuring instrument 1 can be specified intuitively based on the image of “imaging data” and / or the sound of “recorded data”. Therefore, it is possible to more easily specify whether or not the acquired measurement value data Dm is a result of “measurement processing” executed normally.

  Further, in the measurement system 100, the data server 4 transmits condition setting screen data D0 for setting the imaging condition for causing the camera 3 to execute the imaging process to the operation terminal T connected to the Internet 13 "the first". 3 ”and the processing unit 35 that executes the“ second transmission process ”that generates the imaging condition data D <b> 3 based on the response data D <b> 1 transmitted from the operation terminal T and transmits it to the gateway 2. The gateway 2 is configured to execute a “second control process” in which the camera 3 is controlled according to the imaging condition data D3 transmitted from the data server 4 and the imaging process is executed.

  Therefore, according to this measurement system 100, the camera is designated by specifying the “imaging condition” from a location far from the installation location of the camera 3 (a location where the camera 3 cannot be directly operated to generate the imaging data Dp). Since the “imaging process” according to 3 can be executed under an arbitrary condition, the burden on the user regarding the use of the measurement system 100 can be sufficiently reduced.

  Furthermore, according to the measurement system 100, when the measurement value data Dm satisfying a preset condition is transmitted from the gateway 2, the data server 4 includes information such as a graph generated based on the measurement value data Dm. The notification mail Dr including the imaging data Dp associated with the measurement value data Dm is transmitted to the “notification target (predetermined mail address in this example)” via the Internet 13. The processing unit 35 is configured to execute the “fourth transmission process”.

  Therefore, according to the measurement system 100, the measurement satisfying the “notification condition” can be performed even if the user does not regularly download the measurement value data Dm and the imaging data Dp from the data server 4 and check the contents. When the value data Dm is transmitted from the gateway 2 to the data server 4, information that can specify that fact (notification mail Dr in this example) is automatically transmitted. The burden can be further reduced.

  Note that the configurations of the “data transmitting device” and the “measurement system” are not limited to the configuration examples of the gateway 2 and the measurement system 100 described above. For example, in the same manner as the measurement system 100 described above, the “data recording device (data server 4 in the above example)” sets “condition setting data” for setting “data generation conditions” to “arbitrary resources ( “Third transmission process” to be transmitted to “the operation terminal T and the like in the above example” and, unlike the measurement system 100 described above, the “data recording device” transmits from “arbitrary resource”. "Data generation processing" is executed by controlling "Data generation device (Camera 3 in the above example)" via "Data transmission device (Gateway 2 in the above example)" according to "Generation condition data" It is also possible to adopt a configuration including a “third processing unit” that executes the “third control process”.

  According to the “measurement system” having such a configuration, in the same manner as the measurement system 100 described above, a place far away from the place where the “data generation device” is installed (“data generation” Since “data generation conditions” can be specified from any place where the “device” cannot be directly operated) and “data generation processing” by the “data generation device” can be executed under any conditions, the “measurement system” The burden on the user regarding use can be reduced sufficiently.

  In addition, “condition setting data” for the “first processing unit (processing unit 25 in the above example) of the“ data transmitting apparatus (data server 4 in the above example) ”to set the“ data generation condition ”. Is transmitted to “arbitrary resource (the operation terminal T in the above example)”, and the “first processing unit” is “data” according to “generation condition data” transmitted from “arbitrary resource”. It is also possible to adopt a configuration capable of executing the “first control process” for controlling the generation device (camera 3 in the above example) to execute the “data generation process”.

  According to the “data transmission device” and “measurement system” having the above-described configuration, a place (“state specifying data” generated far from the installation location of the “data generation device” is generated in the same manner as the measurement system 100 described above. Because “data generation conditions” can be specified from “a place where the“ data generation device ”cannot be operated directly) and“ data generation processing ”by the“ data generation device ”can be executed under arbitrary conditions. The burden on the user regarding the use of the “data transmission device” and the “measurement system” can be sufficiently reduced.

  Furthermore, the “data generation device” executes “data generation processing” according to preset conditions without generating control of other components, generates “state identification data”, and outputs it to the “data transmission device” It is also possible to adopt a configuration that does this.

  Further, the camera 3 which is an example of the “imaging device” as the “data generation device” generates imaging data Dp (an example of still image data) which is an example of the “imaging data” as the “state specifying data”. However, instead of such a configuration (or in addition to such a configuration), a camera capable of capturing a moving image is referred to as a “data generation device”. It is possible to adopt a configuration in which “imaging data” of a moving image as “state identification data” is generated and transmitted together with measured value data Dm. Further, instead of (or in addition to) the above configuration, a “recording device” as a “data generation device” capable of recording the sound at the installation location of the measuring instrument 1 is used. It is possible to adopt a configuration in which “recording data (voice data)” as “state specifying data” is generated and transmitted together with the measurement value data Dm.

  Even when such a configuration is adopted, “measurement value data” recorded in the “data recording apparatus (data server 4 in the above example)”, “moving image data”, and “audio data” are obtained. This makes it possible to easily identify the state of the measurement site, which was difficult to identify simply by analyzing the `` measured value data '', based on the `` moving image data '' and `` audio data ''. Even a person unfamiliar with the use of the apparatus or system can reliably and easily specify whether or not the acquired “measurement value data” is a result of “measurement processing” executed normally.

  The various “data generation devices” illustrated are not limited to a mode in which one “data transmission device” is installed and used, but a plurality of “data transmission devices” are installed. Can also be used. When a plurality of “data generation devices” are used in combination, a plurality of types of “state identification data” such as still image imaging data, moving image imaging data D, and audio data can be generated. A "data generator" can also be used.

  Further, instead of the configuration in which the measuring instrument 1 and the gateway 2 are connected via the LAN 11, the “measuring instrument” and the “data transmitting apparatus” are connected via a communication path conforming to a short-range wireless communication standard such as Bluetooth (registered trademark). Or a “measuring instrument” and a “data transmission device” can be directly connected via a signal cable. Furthermore, the “measuring instrument” and the “data transmitting apparatus” can be configured as a “single apparatus” (the “measuring instrument” is configured with the function of the “data transmitting apparatus”).

  In addition, the configuration in which the camera 3 is connected to the gateway 2 via the communication cable has been described as an example, but instead of such a configuration, for example, a “data generation device” configured with a network-compatible device is replaced with “data transmission”. A configuration that is used by connecting to a “device” via a LAN, etc., and a “data generating device” is connected to a “measuring device” and a “data generating device” is connected to a “data transmitting device” It is also possible to employ a configuration (none of which is shown) that is used by being connected to.

  Further, the configuration in which the gateway 2 is connected to the data server 4 via the mobile communication network 12 and the Internet 13 has been described as an example. For example, by installing a broadband router function in the “data transmission device”, “data A “transmitting device” is directly connected to the Internet 13, or a broadband router as an external device is connected to the “data transmitting device” and the “data transmitting device” is connected to the Internet 13 via the broadband router. It is also possible to adopt a configuration for connecting to a “data recording device”.

  In addition, when “measurement value data” that satisfies “predetermined state” is transmitted from the “data transmission device”, the “data recording device” executes “fourth transmission processing (notification processing)” However, instead of such a configuration, for example, the “data transmission device” transmits “measurement value data” that satisfies the “predetermined state” to the “data recording device”. In this case, it is possible to adopt a configuration in which “data transmission processing (notification processing)” similar to “fourth transmission processing (notification processing)” is executed. Furthermore, it is also possible to adopt a configuration in which any component does not execute the same process as the “fourth data transmission process (notification process)”.
