Description

The present invention is a data processing device capable of performing processing for associating measurement value data acquired from a measuring instrument with state-specific data capable of identifying at least one of the states of the measuring instrument and the measurement target, and such data processing. It relates to a measurement system configured with a device.

For example, the following patent documents include measurement data generated by a temperature sensor (temperature measuring device) and transmitted via a network communication path (hereinafter, also simply referred to as “network”), and a digital communication output camera (hereinafter, also referred to as “network”). A paperless recorder (hereinafter, also simply referred to as a "recorder") is disclosed, which is configured to be able to receive and record image data generated by a camera) and transmitted via a network.

When recording measurement data and image data by this recorder (monitoring the monitoring target), install a temperature sensor that can measure the temperature of the monitoring target, connect it to the network, and install a camera that can image the monitoring target. Connect to the network and connect the recorder to the network to set the operating conditions. Then, the temperature measurement of the monitored object by the temperature sensor, the imaging of the monitored object by the camera, and the recording of each data by the recorder are started. At this time, the temperature sensor periodically measures the temperature of the monitored object and sequentially transmits the measurement data, and the camera periodically images the monitored object and sequentially transmits the image data.

On the other hand, in the recorder, the image processing unit stores the image data transmitted from the camera in the storage buffer area, and the measurement value input processing unit stores the measurement data transmitted from the temperature sensor in the storage buffer area. At the same time, the alarm processing unit determines whether or not the stored measurement data satisfies the alarm condition. In addition, the alarm processing unit generates an alarm when it determines that the alarm condition is satisfied. In response to this, the file save processing unit follows the control of the trigger processing unit, and a predetermined number of measurement data including measurement data determined to satisfy the alarm condition and a predetermined number of measurement data received before and after the occurrence of the alarm are specified in advance. A save process is executed to specify and save each of the number of image data.

Specifically, the file storage processing unit associates the specified measurement data with each image data and records the data in the data storage recording area. As a result, the specified number of measurement data including the measurement data of the temperature satisfying the alarm condition and the specified number of image data including the image data obtained by capturing the image of the monitoring target at the time when the temperature satisfying the alarm condition is measured mutually. It will be in the associated and recorded state. Therefore, based on the value (temperature) of these measurement data and the image of the image data (image of the monitoring target) recorded in association with each other, the state of the monitoring target at the time when the temperature satisfying the alarm condition is measured is grasped. It becomes possible to do.

Japanese Unexamined Patent Publication No. 2014-202526 (pages 6-12, Fig. 1-18)

However, the recorder disclosed in the above patent document has the following problems to be solved.

Specifically, in the recorder disclosed in the above patent document, the file storage processing unit executes a storage process for storing the measurement data transmitted from the temperature sensor and the image data transmitted from the camera in association with each other. The configuration is adopted. In this case, in this recorder, when the measurement data transmitted from the temperature sensor is received by the digital communication unit, the alarm processing unit determines whether or not the measurement data satisfies the alarm condition, and also determines the alarm condition. When the alarm processing unit generates an alarm after determining that the condition is satisfied, the trigger processing unit controls the file saving processing unit to execute the above saving process.

Therefore, when recording measurement data and image data using this recorder, all of the measurement data generated by the temperature sensor is recorded from the temperature sensor in order to execute the above-mentioned discrimination process by the alarm processing unit. It is necessary to send without omission and without delay. As a result, when using this recorder, when there is no change that the user (monitorer) should recognize in the monitored object, that is, when measurement data or image data that does not need to be recorded in the recorder is generated. Including, the measurement data will be repeatedly transmitted from the temperature sensor to the recorder via the network.

Therefore, in the recorder disclosed in the above patent document, the communication capacity of the entire network is lowered due to the continuous transmission and reception of a large amount of measurement data including the measurement data that is not stored over the network. As a result, the speed of other data communications using this network is slowing down. In this case, in order for the user (monitorer) to quickly grasp the change that has occurred in the monitored object, it is necessary to quickly acquire the measurement data and the image data that can grasp the content of the change in a sufficiently short cycle. .. Therefore, when the number of measurement data transmitted via the network per unit time is reduced in order to avoid a decrease in communication speed, the user (monitorer) can quickly grasp the changes that have occurred in the monitored object. Becomes difficult.

In addition, this type of recorder may be used in the form of connecting a plurality of temperature sensors (temperature measuring instruments) to a network and recording the measurement data from each temperature sensor by one or a plurality of recorders. .. When used in such a usage pattern, the number of measurement data sent and received from each temperature sensor via the network increases according to the number of temperature sensors, so the network is congested depending on the length of the measurement cycle to be set. There is a risk that it will fall into a state and it will be difficult to send and receive measurement data and image data normally.

The second time is specified based on the measurement time.

In the data processing device according to claim 1, the processing unit acquires state-specific data capable of specifying the state of at least one of the measuring instrument and the measurement target from the data generation device in a predetermined first cycle, and also acquires the state-specific data. The first process of storing the state-specific data in the storage unit in association with the first time when the state-specific data is generated, and the determination result in the measuring instrument as to whether or not the measured value satisfying the storage condition is measured in advance When it is specified that the measured value satisfying the storage condition is measured by specifying it in the specified second cycle, the second time when the measured value satisfying the storage condition is measured is specified and measured at the second time.

Just by specifying, it is possible to reliably specify whether or not the measured value data should be associated with the state-specific data and saved, so to determine whether or not a measured value that satisfies the storage conditions has been measured. As a result of eliminating the need for the measuring instrument to send a large amount of measured value data to the data processing device in a short cycle, the measured value data and state to be stored without interfering with the communication of other data in the network to which the measuring instrument is connected. Specific data can be reliably acquired from the measuring instrument and saved.

Since the measured value data and status identification data transmitted to the recording device can be erased from the storage unit, the measured value data and status identification data of a sufficient amount of data can be specified even if the data processing device does not have a large-capacity storage unit. Data can be provided to users. As a result, the manufacturing cost of the data processing device can be sufficiently reduced.

In the data processing apparatus according to claim 3, the processing unit stores the latest state-specific data of the amount of data predetermined in the first processing in the primary storage area of the storage unit by the first-in first-out method, and the second processing. In the above, the state-specific data specified to be included in the predetermined time range is stored in the storage area of the storage unit as the state-specific data associated with the measured value data. Therefore, according to the data processing device according to claim 3 and the measurement system provided with such a data processing device, the measurement target and / or the measuring device is imaged at a sufficiently short cycle to acquire the state-specific data. However, since it is not necessary to store a state-specific data exceeding a specified number, a large-capacity storage unit is not required, and as a result, the manufacturing cost of the data processing device can be sufficiently reduced.

In the data processing device according to claim 4, in the first processing, the processing unit uses the imaging data captured by the imaging device as the data generating device at least one of them, and the recording device as the data generating device is the installation location of the measuring device.

Since it can be specified intuitively, whether or not the associated measurement value data is the result of normally executed measurement processing (whether or not the storage conditions are satisfied due to erroneous measurement), etc. Can be reliably and easily identified.

In the measurement system according to claim 6, the measuring instrument generates condition achievement time data in which the measurement time of the measurement value satisfying the storage condition is identifiable when the measurement value satisfying the storage condition is measured, and also externally.

In, it is specified whether or not the measured value satisfying the storage condition is measured, and the second time is specified based on the measurement time recorded in the condition achievement time data.

Therefore, according to the measurement system according to claim 6, the second time can be reliably and easily specified only by specifying the measurement time recorded in the condition achievement time data acquired from the measuring device in the data processing device. Therefore, it is possible to sufficiently reduce the burden on the processing unit required to identify the determination result in the measuring instrument as to whether or not the measured value satisfying the storage condition has been measured.

It is configured to include a data server 4. Although the measurement system 100 of this example is configured to include a plurality of measuring instruments 1, the number of "measuring instruments" constituting the "measurement system" may be one. Further, although the measurement system 100 of this example is configured to include one camera 3, the number of "data generation devices (imaging device, recording device, etc.)" constituting the "measurement system" may be a plurality of.

Specifically, the processing unit 15 controls the measuring unit 11 to measure the “measured amount” for the measurement target X, and generates the measured value data Dm based on the measured value in the storage unit 16. Remember. In this case, in the measuring instrument 1 in the measuring system 100 of this example, when the processing unit 15 does not measure the measured value satisfying the "event occurrence condition", it takes a relatively long time (for example, several seconds to several minutes) set in advance. When the measured value data Dm (measured value data Dm for monitoring the state of the measurement target X) that records the latest measured value in the cycle of) is generated and the measured value satisfying the "event occurrence condition" is measured. , Measurement value data Dm (detailed measurement value data Dm for analyzing the state of the measurement target X) that records a plurality of measurement values for a preset time including the measurement value measured before the measurement value. The configuration to generate is adopted.

Further, the processing unit 15 determines whether or not the measurement result (measured value) by the measuring unit 11 satisfies the "event occurrence condition" as described above, and determines that the "event occurrence condition" is satisfied. When (an example of "when a measured value satisfying the storage conditions is measured"), the measurement time of the measured value for which such determination is made is recorded as the "event occurrence time", and the event occurrence time data Dt ("condition achievement"). An example of "time data") is generated, and the generated event occurrence time data Dt is stored in the storage unit 16. Further, as an example, the processing unit 15 transmits the measured value data Dm and the event occurrence time data Dt from the communication unit 21 to the gateway 2 via the LAN 5 in response to the transmission request from the gateway 2 (“external”.

It is configured to be connectable to network devices such as the server 4. As shown in FIG. 3, the gateway 2 includes a communication unit 21, 22, an operation unit 23, a display unit 24, a processing unit 25, and a storage unit 26, and a camera 3 is connected to the gateway 2.

The communication unit 21 is composed of a network adapter that can be connected to the LAN 5 in the same manner as the measurement unit 11 of the measuring instrument 1, and is connected to a network device such as the measuring instrument 1 according to the control of the processing unit 25 to transmit and receive various data. .. As an example, the communication unit 22 is composed of a mobile communication module that can be connected to the mobile communication network 6, and under the control of the processing unit 25, the gateway 2 is connected to the Internet 7 (to the Internet 7) via the mobile communication network 6. Connect to various connected network devices). The operation unit 23 includes a plurality of operation switches (not shown) capable of executing operation conditions for setting the operating conditions of the gateway 2 and setting operations for the operating conditions of the camera 3, and processes operation signals according to the switch operations. Output to 25. The display unit 24 displays various information indicating the operating state of the gateway 2 under the control of the processing unit 25.

The processing unit 25 comprehensively controls the gateway 2. This processing unit 25 is an example of the “processing unit”, executes the imaging data storage process 50 shown in FIG. 5, and receives the imaging data Dp (“state identification”) from the camera 3 in a predetermined “first cycle”. An example of "data") is acquired, and the imaged data Dp is stored in the storage unit 26 in association with the "first time (imaging time of the imaged data Dp)" in which the acquired imaged data Dp is generated ("first time"). An example of "processing"). In this case, in the gateway 2 of this example, the processing unit 25 stores the imaged data Dp of the amount of data predetermined in the above-mentioned "first processing" in the storage unit 26 by the first-in first-out method, and also stores the image data Dp in the storage unit 26 by the first-in first-out method. A configuration in which the imaging data Dp specified to include the "first time" within the predetermined time range in the "second processing" is excluded from the deletion target as the earliest imaging data Dp in the "first processing". Has been adopted.

Further, when the measured value data Dm transmitted from the measuring instrument 1 via the LAN 5 is received by the communication unit 21, the processing unit 25 stores the measured value data Dm in the storage unit 26 (“from the measuring instrument”. An example of the process of "acquiring the measured value data of"). Further, the processing unit 25 executes the measurement result data recording process 60 shown in FIG. 6 to acquire the event occurrence time data Dt from each measuring instrument 1 in a predetermined “second cycle”, and each measuring instrument. It is periodically specified whether or not the measured value satisfying the "event occurrence condition" in 1 is measured.

Further, when the measured value satisfying the "event occurrence condition" is measured, the processing unit 25 specifies the "second time (measurement time)" in which the measured value satisfying the "event occurrence condition" is measured. , The measured value data Dm including the measured value measured at the "second time", and the associated "first time (imaging time)" within a predetermined time range including the "second time". The measurement result data Dr is generated by associating the imaging data Dp included in the above with each other (an example of "second processing"). In this case, in this example, as an example, a process of generating the measurement result data Dr by compressing the measured value data Dm and the imaging data Dp to be associated with each other while archiving them is executed as the "second process". ..

Further, when the processing unit 25 generates new measurement result data Dr (an example of "when a predetermined transmission condition is satisfied"), the processing unit 25 receives the measurement result data Dr ("measures associated with each other"). An example of "value data and state-specific data") is transmitted to the data server 4 for recording (an example of "third processing"). The specific contents of the imaging data storage process 50 (“first process”) and the measurement result data recording process 60 (“second process” and “third process”) will be described in detail later. explain. The storage unit 26 is an example of the “storage unit”, and is generated by the operation program of the processing unit 25, the measured value data Dm received by the communication unit 21, the imaging data Dp output from the camera 3, and the processing unit 25. The measurement result data Dr and the like to be performed are stored.

The camera 3 is an example of an “imaging device” as a “data generation device”, and as shown in FIGS. 1 and 3, the camera 3 is connected to the gateway 2 via a signal cable as an example. As an example, the camera 3 executes an "imaging process" as a "data generation process" under the control of the gateway 2 (according to a remote operation by the gateway 2) to image the measurement target X and / or the measuring instrument 1. Data Dp (“state-specific data” that can specify at least one of the states of the measuring instrument that is executing the measurement process and the measurement target whose measurement target is being measured by the measuring instrument: “state-specific data” that can identify at least one state: image data of a still image as an example ) Is generated, and the generated imaging data Dp is output to the gateway 2.

The data server 4 is an example of a “data recording device”, which records the measurement result data Dr transmitted from the gateway 2 and receives a request from an arbitrary information processing terminal (for example, a data processing terminal T described later). Correspondingly, the measurement result data Dr can be transmitted via the Internet 7. As shown in FIG. 4, the data server 4 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.

The recording unit 31 is configured to include a large-capacity recording medium (hard disk drive or the like) capable of recording measurement result data Dr or the like transmitted from the gateway 2. The communication unit 32 is composed of a communication unit that can be connected to the Internet 7, and under the control of the processing unit 35, executes a measurement result data Dr reception process, a notification mail transmission process described later, and the like. The operation unit 33 includes a keyboard and a pointing device (not shown) capable of executing the operation of setting the operating conditions of the data server 4. The display unit 34 displays various information indicating the operating state of the data server 4.

The processing unit 35 comprehensively controls the data server 4. Specifically, when the measurement result data Dr transmitted from the gateway 2 is received by the communication unit 32, the processing unit 35 stores the measurement result data Dr in the storage unit 36. Further, the processing unit 35 reads the measurement result data Dr from the storage unit 36 in response to a request from an external device such as the data processing terminal T, and transmits the measurement result data Dr from the communication unit 32 to the external device via the Internet 7. Further, when the processing unit 35 is instructed by the gateway 2 to send an "event occurrence notification mail" for notifying that an event specified in advance has occurred at the measurement site for the measurement target X, the processing unit 35 "designates in advance". Executes the process of sending a notification email to the notification target (preset email address). The storage unit 36 temporarily stores the calculation result of the processing unit 35 and various data such as the above-mentioned measurement result data Dr.

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

When using this measurement system 100, each measuring instrument 1, gateway 2 and camera 3 are installed at a measurement site where the measurement target X exists. In reality, prior to the start of the installation work, a gateway that allows user registration (issuance of an ID and password for authentication) of a person who has the authority to use the data server 4 and connection to the mobile communication network 6. 2 (sim card, etc. (not shown) attached to gateway 2) is registered, but in order to facilitate understanding of the configuration of the "data processing device" and "measurement system", these registration operations and registration results The description of the based authentication process will be omitted.

First, the measurement sensor of each measuring instrument 1 is attached to the measurement target X, and the communication unit 12 of each measuring instrument 1 is connected to the gateway 2 via the network cable constituting the LAN 5 (via the switching hub if necessary). Connect to the communication unit 21 of. The operating conditions of each measuring instrument 1 and the operating conditions of the gateway 2 may be carried out before being installed at the measurement site, or may be carried out at the measurement site as one of the installation work. Further, by operating the operation unit 23 of the gateway 2, the data server 4 can be connected to the data server 4 via the mobile communication network 6 and the Internet 7.

Further, the camera 3 is placed at a position where at least one of the measurement target X and the measuring instrument 1 (an imaging target that can generate imaging data Dp useful for identifying the cause when an abnormal measured value is measured) can be imaged. Set and connect to gateway 2. It should be noted that the operating conditions of the camera 3 (various imaging conditions such as the resolution of the generated imaging data Dp and the data compression rate) are also carried out before the installation at the measurement site, or as one of the installation operations at the measurement site. It is carried out in. As described above, a series of preparatory work using the measurement system 100 is completed.

Next, the processing by each measuring instrument and the gateway 2 is started. At this time, in each measuring instrument 1, a "measurement process" is executed, and a predetermined measurement amount for the measurement target X is measured in a preset measurement cycle. In this case, in the measuring instrument 1 of this example, as described above, the processing unit 15 determines whether or not the measured value satisfying the "event occurrence condition" is measured by the measuring unit 11. Further, when the measured value satisfying the "event occurrence condition" is not measured, the processing unit 15 performs the latest measured value (instantaneous value) in a cycle of a preset time (for example, several seconds to several minutes: 10 seconds as an example). ) Is recorded, and the measured value data Dm is generated and stored in the storage unit 16.

In this measurement system 100, the measured value data Dm generated when the measured value satisfying the "event occurrence condition" is not measured is the data server 4 via the LAN 5, the gateway 2, the mobile communication network 6, and the Internet 7. The configuration is adopted in which the data is sequentially transmitted to. As a result, the data server 4 or an information processing terminal (data processing terminal T, etc.) that can access the data server 4 can refer to the contents of the measured value data Dm to grasp the outline of the state of the measurement target X. Although it is possible to monitor the measurement target X, the measured values that satisfy the "event occurrence conditions" are measured in order to facilitate understanding of the configurations of the "data processing device" and "measurement system". The description of the measured value data Dm generated when this is not performed will be omitted.

Further, when a measured value satisfying the "event occurrence condition" is measured, the processing unit 15 performs a preset time (several seconds to several tens of seconds: as an example) including the measured value measured before the measured value. The storage unit 16 generates the measured value data Dm that records the measured values within 5 seconds before the time when the event occurrence condition is satisfied, and 20 seconds from the time when the event occurrence condition is satisfied until 15 seconds elapse. To memorize. Further, when a measured value satisfying the "event occurrence condition" is measured, the event occurrence time data Dt ("condition achievement time data") is generated and stored with the measurement time of such the measured value as the "event occurrence time". Store in part 16.

After that, in the measuring instrument 1, when the preset end condition of the measurement process is satisfied, when the end of the measurement process is instructed by the operation of the operation unit 13, or the power supply of the measuring instrument 1 is cut off. Until then, the above series of processes is repeatedly executed.

On the other hand, in the gateway 2, the processing unit 25 starts the imaging data storage process 50 shown in FIG. 5 in response to the instruction to start the process. In the imaging data storage process 50, the processing unit 25 first controls the camera 3 to image the imaging target and acquires (receives) the imaging data Dp (step 51). Next, the processing unit 25 determines whether or not a predetermined number of imaging data Dp is stored in the primary storage area of the storage unit 26 (a storage area specified to store the imaging data Dp according to the first-in first-out method). (Step 52).

At this time, in this example, as an example, the "operating conditions" of the gateway 2 are set so as to store the latest tens to hundreds (120 as an example) of imaging data Dp in the primary storage area. There is. Therefore, immediately after the start of processing, when the number of stored imaging data Dp is less than the specified number, the processing unit 25 generates the imaging data Dp acquired from the camera 3 to generate the imaging data Dp. The data is stored in the primary storage area of the storage unit 26 in association with the time (imaging time: an example of the “first time”) (step 53). Further, the processing unit 25 waits until a preset waiting time (several hundred milliseconds to several tens of seconds: 1 second as an example) elapses (step 54), and when the waiting time elapses, the camera 3 Is controlled to image the imaging target and the imaging data Dp is acquired (step 51).

At this time, when it is determined that the specified number of imaging data Dp is not stored in the primary storage area of the storage unit 26 (step 52), the acquired imaging data Dp is stored in the primary storage area. Further, when it is determined by repeating each process of steps 51 to 54 that a specified number of imaging data Dp are stored in the primary storage area of the storage unit 26 (step 52), the stored imaging data Dp The earliest imaging data Dp is deleted from the primary storage area (step 55), and the latest imaging data Dp acquired in the immediately preceding step 51 is stored in the primary storage area (step 53). The process of erasing the latest imaging data Dp and storing the latest imaging data Dp means a process of overwriting the latest imaging data Dp in the storage area of the latest imaging data Dp.

In this way, in a state in which a predetermined number (120 in this example) of the latest imaging data Dp is set to be stored in the primary storage area of the storage unit 26, a preset standby time (120 in this example) ( In this example, each time 1 second) elapses (an example in which the "first cycle" is a 1-second cycle), the camera 3 is controlled to image the image-imaging target, and new image-imaging data Dp is acquired and accumulated. In the example, the imaging data Dp that can specify the latest state of the imaging target within 2 minutes is stored in the primary storage area of the storage unit 26. After that, the processing unit 25 continuously executes the imaging data storage process 50 until an operation for instructing the end of the process is performed or the power supply of the gateway 2 is cut off.

Further, in the gateway 2, the processing unit 25 executes the measurement result data recording process 60 shown in FIG. 6 in parallel with the imaging data storage process 50 described above. In the measurement result data recording process 60, the processing unit 25 first requests each measuring instrument 1 to transmit the latest event occurrence time data Dt via the LAN 5 (step 61).

At this time, when the measured value satisfying the "event occurrence condition" is not measured in any of the measuring instruments 1, the event occurrence time data Dt is not generated in each measuring instrument 1, so that the event occurrence time data Dt is Not sent. Therefore, it is determined that the event occurrence time data Dt is not transmitted from any of the measuring instruments 1 (step 62), and the process waits until the preset waiting time (several seconds to several minutes: 1 minute as an example) elapses. (Step 63) When the waiting time has elapsed, each measuring instrument 1 is requested to transmit the latest event occurrence time data Dt again (example in which the "second cycle" is a 1-minute cycle: step 61).

On the other hand, when a measured value satisfying the "event occurrence condition" is measured in any of the measuring instruments 1, the time when the "event occurrence condition" is satisfied in the measuring instrument 1 (an example of the "second time") is set. Since the recorded event occurrence time data Dt is generated and stored in the storage unit 16, this event occurrence time data Dt is transmitted to the gateway 2 as the latest event occurrence time data Dt. Therefore, the processing unit 25 determines that the event occurrence time data Dt has been transmitted (step 62), and the event occurrence time data Dt has the event occurrence time previously acquired from the measuring instrument 1 that has transmitted the event occurrence time data Dt. It is determined whether or not the time is later than the time recorded in the data Dt (the time when the previous event occurred) (step 64).

In this case, when the measurement value satisfying the "event occurrence condition" is measured by any of the measuring instruments 1 and the event occurrence time data Dt is generated, the measurement value satisfying the "event occurrence condition" is again measured in the measuring instrument 1. Even if it is not measured, the event occurrence time data Dt generated when the measured value that finally satisfies the "event occurrence condition" is measured is stored in the storage unit 16. Therefore, the same event occurrence time data Dt is transmitted to the gateway 2 each time the processing unit 25 of the gateway 2 executes the process of step 61 (request for transmission of the latest event occurrence time data Dt). Under such circumstances, the processing unit 25 sets the time of the event occurrence time data Dt newly acquired by the transmission request in step 61 (event occurrence time) to the time of the previously acquired event occurrence time data Dt (event occurrence time). It is determined that the time is the same, and the device waits until the preset waiting time elapses (step 63).

On the other hand, when the measured value satisfying the "event occurrence condition" is measured for the first time in any of the measuring instruments 1 and the event occurrence time data Dt is generated, it corresponds to the "previously acquired event occurrence time data Dt". Since the event occurrence time data Dt does not exist, the time of the event occurrence time data Dt (event occurrence time) acquired by the transmission request in step 61 is different from the "time of the previously acquired event occurrence time data Dt". It is determined that there is (step 64). Further, when the measured value satisfying the "event occurrence condition" is measured again in any of the measuring instruments 1 and new event occurrence time data Dt is generated, the event occurrence time data Dt acquired by the transmission request in step 61 It is determined that the time (event occurrence time) is different from the time (previous event occurrence time) of the event occurrence time data Dt acquired last time (step 64).

As described above, when the "event occurrence time" specified based on the acquired event occurrence time data Dt in step 64 is different from the previous "event occurrence time" (or the "event occurrence condition" is satisfied. When the measured value is measured for the first time), the processing unit 25 is recorded in the event occurrence time data Dt acquired in step 61 from the imaging data Dp stored in the primary storage area of the storage unit 26. The imaging data Dp of the imaging time corresponding to the "event occurrence time" is specified and copied from the primary storage area to the normal storage area (an example of the "storage area") ("storage unit as state-specific data associated with measured value data". An example of the process of "storing in the storage area of": step 65). In this case, as an example, the imaging data Dp captured in 20 seconds from 5 seconds before the specified "event occurrence time" to 15 seconds elapses from the "event occurrence time" is specified and deleted. exclude.

Next, the processing unit 25 requests the measuring instrument 1 that has acquired the event occurrence time data Dt of the new “event occurrence time” to transmit the latest measured value data Dm, and also transmits the transmitted measured value data Dm. It is stored in the storage unit 26 (step 66). In this case, in the measuring instrument 1 that has transmitted the new event occurrence time data Dt, as described above, in parallel with the generation processing of the event occurrence time data Dt, the event occurrence time starts from 5 seconds before the event occurrence time. The measured value data Dm that records each measured value measured in 20 seconds from the time when 15 seconds elapses is generated and stored in the storage unit 16. Therefore, the measured value data Dm is transmitted from the measuring instrument 1 in response to the transmission request from the gateway 2 (processing unit 25).

Subsequently, the processing unit 25 generates the measurement result data Dr by associating the imaging data Dp excluded from the deletion target and the acquired measurement value data Dm with each other, and stores the generated measurement result data Dr in the storage unit 26. (Step 67). In this case, at the time of generation of the measurement result data Dr, the measurement value data Dm generated when the measurement value satisfying the "event occurrence condition" is not measured and transmitted from the measuring instrument 1 to the gateway 2 or another measuring instrument. The measured value data Dm and the like transmitted from 1 are stored in the storage unit 26. Therefore, the processing unit 25 transmits the event occurrence time data Dt acquired by the transmission request in step 61 from the plurality of measurement value data Dm, and the “event” recorded in the event occurrence time data Dt is recorded in the measuring instrument 1. The measurement value data Dm generated including the measurement value measured at the “occurrence time” is specified, and the measurement result data Dr is generated in association with the imaging data Dp.

Next, the processing unit 25 transmits the measurement result data Dr (an example of "measurement value data and state identification data associated with each other") from the communication unit 22 to the data server 4 via the mobile communication network 6 and the Internet 7. It is transmitted and recorded (step 68). At this time, in the data server 4, when the measurement result data Dr transmitted from the gateway 2 is received by the communication unit 32, the processing unit 35 associates the measurement result data Dr with the gateway 2 and records the data. Have 31 record. In the above example, "when the measurement result data Dr in which the measured value data Dm and the imaging data Dp are associated" is generated corresponds to "when the predetermined transmission condition is satisfied".

Subsequently, the processing unit 25 transmits a predetermined control command from the communication unit 22 to the data server 4 via the mobile communication network 6 and the Internet 7, so that the measurement target X satisfies the “event occurrence condition”. Requests the transmission of an "event occurrence notification mail" notifying that the state has been measured (step 69). Further, the processing unit 25 waits until the preset waiting time (1 minute in this example) elapses (step 63), and when the waiting time elapses, the latest for each measuring instrument 1 is again updated. Request the transmission of event occurrence time data Dt. After that, in the gateway 2, each process after step 61 is repeatedly executed until the process stop is instructed by the operation of the operation unit 23 or the process stop is instructed by the control command from the data server 4.

On the other hand, in the data server 4, the processing unit 35 generates an "event occurrence notification mail" addressed to a preset notification target (preset mail address), and transmits the generated "event occurrence notification mail". .. As a result, the person who receives the "event occurrence notification mail" sent from the data server 4 has the measurement target X in the "state in which the measured value satisfying the event occurrence condition has been measured" based on the content of the mail. Recognize. At this time, the user accesses the data server 4 by operating the data processing terminal T or the like as necessary, and the measurement result data Dr (measurement value data Dm and imaging data Dp) recorded in the recording unit 31. Is downloaded to analyze the measured values for the measurement target X in detail, and these states are confirmed based on the images captured by the measurement target X and / or the measuring instrument 1.

Therefore, in the measurement system 100 of this example, the user does not have to periodically perform the work of downloading the measurement result data Dr (measurement value data Dm and imaging data Dp) from the data server 4 and checking the contents. Since the "event occurrence notification mail" is sent from the data server 4 when the measured value satisfying the "event occurrence condition" is measured, the measurement result data is received from the data server 4 when the "event occurrence notification mail" is received. As a result of being able to grasp the state of the measurement target X simply by downloading Dr, the burden on the user is sufficiently reduced.

As described above, in the gateway 2, the processing unit 25 acquires the imaging data Dp capable of specifying the state of at least one of the measuring instrument 1 and the measurement target X from the camera 3 in a predetermined “first cycle”. At the same time, was the measured value satisfying the "first process" of storing the acquired image data Dp in the storage unit 26 in association with the generated "first time" and the "preservation condition"? When it is specified that the determination result in the measuring device 1 is specified in the predetermined "second cycle" and the measured value satisfying the "preservation condition" is measured, the measured value satisfying the "preservation condition" is measured. In addition to specifying the "second time", the measured value data Dm including the measured value measured at the "second time", and the associated "first time" are the "second time". Including "second processing" that correlates the imaging data Dp included within the predetermined time range (in this example, the measurement result data Dr is generated based on the measured value data Dm and the imaging data Dp). It is configured to be executable. Further, the measurement system 100 is configured to include the gateway 2 and the measuring instrument 1 described above.

Therefore, according to the gateway 2 and the measurement system 100, the determination result in the measuring instrument 1 regarding "whether or not the measured value satisfying the storage condition (event occurrence condition) is measured" is obtained in a sufficiently long "second cycle". Only by specifying (in this example, the event occurrence time data Dt is acquired from the measuring instrument 1), it is possible to reliably specify whether or not the measured value data Dm and the imaging data Dp should be associated and saved. Therefore, it is necessary to have the "measuring instrument" transmit a large amount of measured value data Dm to the "data processing device" in a short cycle in order to determine "whether or not the measured value satisfying the storage condition (event occurrence condition) has been measured". As a result, the measured value data Dm and the imaging data Dp to be stored can be reliably acquired from the measuring instrument 1 and stored without interfering with the communication of other data in the LAN 5. As a result, even when the "measurement process" is executed by each of the plurality of measuring instruments 1, the measured value data Dm to be stored can be reliably acquired from each measuring instrument 1 together with the imaging data Dp.

Further, in the gateway 2, when the predetermined "transmission condition" is satisfied, the processing unit 25 transmits the measurement result data Dr (measured value data Dm and imaging data Dp associated with each other) to the data server. The "third process" of transmitting to 4 and recording is executed. Therefore, according to the gateway 2 and the measurement system 100, the measurement result data Dr that is associated with the measurement value data Dm and the imaging data Dp is transmitted to the data server 4 and recorded, so that the measurement result data transmitted to the data server 4 is recorded. Since the measured value data Dm and the imaging data Dp of Dr can be erased from the storage unit 26, the measurement result data Dr (measured value data) having a sufficient amount of data even if the gateway 2 is not equipped with a large-capacity storage unit. Dm and imaging data Dp) can be provided to the user. As a result, the manufacturing cost of the gateway 2 can be sufficiently reduced.

Further, in the gateway 2, the processing unit 25 stores the latest imaged data Dp of the amount of data predetermined in the “first processing” in the primary storage area of the storage unit 26 by the first-in first-out method, and also “second”. The imaging data Dp specified to be included in the predetermined time range in the "processing" is stored in the storage area of the storage unit 26 as the imaging data Dp associated with the measured value data Dm. Therefore, according to the gateway 2 and the measurement system 100, even if the measurement target X and / or the measuring instrument 1 is imaged at a sufficiently short cycle to acquire the imaging data Dp, the imaging data Dp exceeding the specified number can be stored. Since it is unnecessary, as a result of eliminating the need for a large-capacity storage unit, the manufacturing cost of the gateway 2 can be sufficiently reduced.

Further, in the gateway 2, the processing unit 25 takes an image of at least one of the measuring device 1 and the measurement target X by the camera 3 which is the “imaging device” as the “data generating device” in the “first processing”. The data Dp is acquired as "state-specific data". Therefore, according to the gateway 2 and the measurement system 100, the state of the measurement target X and the measurement device 1 can be intuitively specified based on the image of the imaging data Dp, so that the associated measurement value data Dm can be obtained. , Whether or not it is the result of normally executed "measurement processing" (whether or not the event occurrence condition is satisfied due to erroneous measurement), etc. can be reliably and easily specified.

Further, in this measurement system 100, the measuring instrument 1 records the event occurrence time data Dt in which the measurement time of the measured value satisfying the "preservation condition" is identifiable when the measured value satisfying the "preservation condition" is measured. It is configured to be able to generate and transmit event occurrence time data Dt in response to a request from an external device, and the processing unit 25 of the gateway 2 transmits the event occurrence time data Dt from the measuring instrument 1 in the "second process". It is specified whether or not the measured value acquired in the "second cycle" and satisfies the "preservation condition" is measured in the measuring instrument 1, and is based on the "measurement time" recorded in the event occurrence time data Dt. Identify the "second time".

Therefore, according to this measurement system 100, the "second time (event occurrence time)" can be determined only by specifying the "measurement time" recorded in the event occurrence time data Dt acquired from the measuring instrument 1 at the gateway 2. Since it can be specified reliably and easily, the burden on the processing unit 25 required to specify "the determination result in the measuring instrument whether or not the measured value satisfying the storage condition is measured" can be sufficiently reduced.

The configurations of the "data processing device" and the "measurement system" are not limited to the above-mentioned examples of the configurations of the gateway 2 and the measurement system 100. For example, the camera 3 which is an example of the "imaging device" as the "data generating device" generates the imaging data Dp of the still image which is an example of the "imaging data" as the "state identification data" and obtains the measured value data Dm. The associated configuration has been described as an example, but instead of (or in addition to) such a configuration, a camera capable of shooting moving images is used as an "imaging device" as a "data generator". Then, it is possible to adopt a configuration in which "imaging data" of a moving image as "state-specific data" is generated and transmitted together with the measured value data Dm.

Also, instead of (or in addition to) the above configuration, a "recording device" as a "data generator" capable of recording the sound of the installation location of the measuring instrument 1 is used. It is possible to adopt a configuration in which "recorded data (sound data)" as "state-specific data" is generated and transmitted together with the measured value data Dm. In this way, in the "first process", the "processing unit" identifies the "state of the recorded data" in which the "recording device" as the "data generator" records the sound of the installation location of the "measuring instrument". By acquiring as "data", the state of the measurement target X and the measuring instrument 1 can be intuitively specified based on the sound of the "recorded data", so that the associated measurement value data Dm is executed normally. Whether or not it is the result of the "measurement process" performed (whether or not the event occurrence condition is satisfied due to erroneous measurement) can be reliably and easily specified.

Further, the configuration in which the gateway 2 is connected to the data server 4 via the mobile communication network 6 and the Internet 7 has been described as an example. For example, by equipping the “data processing device” with a broadband router function, “data” can be obtained. The "processing device" is directly connected to the Internet 7, or the "data processing device" is connected to a broadband router as an external device and the "data processing device" is connected to the Internet 7 via the broadband router. It is also possible to adopt a configuration in which the data is connected to a "data recording device".

Further, a data server 4 connectable via the mobile communication network 6 and the Internet 7 is used as a "data recording device" to transmit and record measurement result data Dr (measured value data Dm and imaging data Dp) from the gateway 2. However, the “data recording device” is not limited to this, and for example, a recording device (not shown) such as a “network hard disk drive” connected to the LAN 5 together with each measuring instrument 1 is “data recorded”. A configuration in which measurement result data Dr is transmitted from the gateway 2 as a "device" and recorded, or a recording device (not shown) directly connected to the gateway 2 via a signal cable is used as a "data recording device" from the gateway 2. A configuration can be adopted in which the measurement result data Dr is transmitted and recorded.

Further, the configuration in which the camera 3 is connected to the gateway 2 via the signal cable has been described as an example, but instead of such a configuration, for example, a “data generator” composed of a network compatible device is used as the measuring instrument 1. A configuration in which the "data generator" is connected to the gateway 2 via the LAN 5 and used by connecting to the LAN 5, and the "data generator" is connected to the "measuring instrument" and via the "measuring instrument". It is also possible to adopt a configuration in which a "data generator" is connected to the gateway 2 and used (none of which is shown). Further, instead of the configuration in which the measuring instrument 1 and the gateway 2 are connected via LAN 5, the "measuring instrument" and the "data processing device" are provided via a communication path conforming to a short-range wireless communication standard such as Bluetooth (registered trademark). ", Or the" measuring instrument "and the" data processing device "can be directly connected via a signal cable (not shown).
