  However, the measurement system disclosed by the applicant has the following problems to be improved. That is, the measurement system disclosed by the applicant employs a configuration in which measurement data recorded in each measurement data recording device is collected by a measurement data collection device and transferred to a personal computer.

  In this case, in this type of measurement system, in order to reduce the size of the measurement data recording device and reduce the manufacturing cost, a storage element having a small storable capacity tends to be mounted as a RAM for recording measurement data. is there. Therefore, in this type of measurement system, the measurement data recorded by the measurement data collection device is recorded in order to prevent the measurement data from being recorded due to the lack of a storable area. There is a configuration that employs a configuration that avoids a situation in which a lack of a storable area occurs due to deletion from a device. However, in a measurement system that has a configuration in which measurement data is erased from the measurement data recording device when the collection is completed, for example, the measurement data collection is erroneously performed when the measurement data is transferred from the measurement data collection device to the personal computer. When the measurement data in the apparatus is erased, there is a problem that the measurement data that has been erased by mistake has already been erased from the measurement data recording apparatus, and therefore this measurement data cannot be collected again.

  Therefore, the applicant defines a plurality of ring buffer type storage areas in the RAM of the measurement data recording apparatus, records the measurement data in each storage area by the first-in first-out method, and completes the collection by the measurement data collection apparatus. However, a configuration is adopted in which the measurement data is stored in the measurement data recording device without being erased. By adopting such a configuration, it is possible not only to record measurement data even when multiple measurement processes are executed without mounting a storage element having a large storable capacity, but also to provide a measurement data collection device. Even after the collection by is completed, the measurement data in the measurement data recording device can be collected to the data relay device any number of times until new measurement data is overwritten. However, in a measurement system that employs a configuration in which the measurement data of the measurement data recording device is not erased when collection is completed, the second and subsequent collection processes include measurement data that has already been collected during the last collection process. Measurement data will be collected. Therefore, it is difficult to shorten the time required for collecting measurement data, and it is necessary to mount a large-capacity RAM in the measurement data collection device due to redundant collection of the same measurement data. There is a problem that it is difficult to reduce costs.

  In addition, when a large number of measurement data recording devices are used for recording measurement data by this type of measurement system, each measurement data is collected using a plurality of measurement data collection devices in order to shorten the time required for collecting the measurement data. It is preferable to collect the measurement data from the recording device in parallel. In this regard, in the measurement system disclosed by the applicant, it is possible to collect measurement data from each measurement data recording device using two or more measurement data collection devices. Specifically, as an example, when 20 measurement data recording devices are used, the measurement data is collected using two measurement data collection devices, so that 20 measurement data collection devices are used. Compared to collecting measurement data from a single measurement data recording device, measurement data can be collected in about half the time.

  However, in a measurement system that employs a configuration in which measurement data is collected using a plurality of measurement data collection devices, each time a collection process is performed when the collection processing is executed multiple times for one measurement data recording device. The measurement data is collected by the different measurement data collection devices, and a series of measurement data recorded by one measurement data recording device is dispersed and collected in a plurality of measurement data collection devices. There is. In such a state, a series of measurement data distributed and collected by a plurality of measurement data collection devices is collected, for example, in one personal computer, and arranged in the order of execution of measurement processing to be one continuous.

  In response to this, in the measurement data collection device 2, the control unit 26 specifies the measurement data recording device 1 that is to collect the measurement data Dr in the measurement data collection processing 40 based on the acquired recording device identification code D1a. At the same time, the presence / absence of the recovery record of the measurement data Dr from the specified measurement data recording device 1 (whether there is a track record of recovering the measurement data Dr in the past) is determined based on the recording device information D2b (step 42). At this time, when there is no record of recovery of the measurement data Dr from the measurement data recording device 1 specified based on the recording device identification code D1a (individual information (identification code of the measurement data recording device 1 of the acquired recording device identification code D1a) ) Is not recorded in the recording device information D2b), for example, the control unit 26 outputs a buzzer sound from a speaker (not shown) and “from the recording device from which the measurement data is to be collected This is the first time that the measurement data is collected by the message “Is it OK to continue the collection process of the measurement data?” Is displayed on the display unit 24 (an example of “notification to that effect”: Step 43 ).

  At this time, when the cancel switch of the operation unit 23 is operated by the user (when there is no collection execution instruction) (step 44), the control unit 26 ends the measurement data collection process 40. Further, when the user operates the OK switch of the operation unit 23 (when a collection execution instruction is issued) (step 44), the control unit 26 records all the data recorded in the measurement data recording device 1. The measurement data Dr is collected (step 45). Specifically, the control unit 26 controls the communication unit 21 to send a transmission request signal S2 for requesting transmission of all measurement data Dr recorded to the measurement data recording device 1 and the storage unit 22. The stored collection device identification code D2a is transmitted. In response to this, in the measurement data recording device 1, the control unit 16 reads all the measurement data Dr stored in each storage area of the storage unit 22 and controls the communication unit 15 to control the measurement data collection device 2. To send to.

  Further, the control unit 16 corresponds to the measurement data Dr transmitted to the measurement data collection device 2 (the measurement data Dr most recently collected by the measurement data collection device 2) and the latest collection data date / time information D1b and the latest collection data. The number information D1c is updated, and the collection device information D1d is updated in correspondence with the collection device identification code D2a of the measurement data collection device 2 that collected the measurement data Dr. Specifically, the control unit 16 updates the latest measurement data Dr (measurement data Dr that has been collected by the measurement data collection device 2) among the measurement data Dr transmitted to the measurement data collection device 2 in response to the transmission request signal S2. The latest collection data date information D1b is updated to the measurement date and time of the measurement data Ds (that is, the recording date and time of the measurement data Dr) which is the basis of the latest measurement data Dr) of the latest measurement data Dr. The latest collection data number information D1c is updated to the number (data number) of the storage area in which is stored. Further, the control unit 16 updates the collection device information D1d to the collection device identification code D2a (individual information of the measurement data collection device) transmitted from the measurement data collection device 2 together with the transmission request signal S2.

  In the measurement data collection device 2, the control unit 26 stores the measurement data Dr transmitted from the measurement data recording device 1 and received by the communication unit 21 (measurement data Dr collected from the measurement data recording device 1). Remember me. Further, the control unit 26 updates the recording device information D2b in correspondence with the recording device identification code D1a acquired from the measurement data recording device 1 from which the measurement data Dr has been collected, and at the same time the measurement data Dr collected from the measurement data recording device 1. Update the individual latest collection data date / time information D2c and individual latest collection data number information D2d for the measurement data recording apparatus 1 that collected the measurement data Dr in correspondence with the latest measurement data Dr (step 46). The measurement data collection process 40 ends. Specifically, the control unit 26 updates the recording device information D2b to the acquired recording device identification code D1a (individual information of the measurement data recording device 1), and the individual latest collected data date and time for the measurement data recording device 1 described above. The information D2c is updated to the recording date and time of the latest measurement data Dr, and the individual latest collection data number information D2d for the measurement data recording device 1 is stored in the storage area in the storage unit 22 in which the latest measurement data Dr is stored. The data is updated to a number (data number), and when the update of each information is completed, the measurement data collection process 40 is terminated.

  On the other hand, when it is determined that there is a record of collecting the measurement data Dr from the measurement data recording device 1 specified based on the acquired recording device identification code D1a (when the measurement data Dr has been collected in the past: recording device identification) When the code of the measurement data recording device 1 specified based on the code D1a exists in the recording device information D2b (step 42), the control unit 26 tries to collect the measurement data Dr by this measurement data collection processing 40. It is determined whether or not the measurement data collection device 2 that has recently collected the measurement data Dr from the measurement data recording device 1 is the device itself (that is, the device that has collected the measurement data Dr the latest) (step 47). Specifically, the control unit 26 matches the device (self) specified based on the collection device identification code D2a stored in the storage unit 22 with the device specified based on the acquired recording device identification code D1a. It is determined whether or not to do so.

  At this time, when the two devices do not match, that is, when the device itself is not the device that has recently collected the measurement data Dr, the control unit 26 outputs a buzzer sound from a speaker (not shown) as an example, The display unit 24 displays a message “Measurement data is being collected from another recording device from the recording device that is trying to collect the data. Is it OK to continue collecting the measurement data from this recording device?”. (An example of “notification to that effect”: step 48). At this time, when the cancel switch of the operation unit 23 is operated by the user (when there is no collection execution instruction) (step 49), the control unit 26 ends the measurement data collection processing 40.

  Further, when the user operates the OK switch of the operation unit 23 (when a collection execution instruction is issued) (step 49), the control unit 26 outputs a buzzer sound from a speaker (not shown) as an example. At the same time, a message “Do you want to collect data excluding the measurement data already collected by another collection device?” Is displayed on the display unit 24 (step 50). At this time, when the user operates the OK switch of the operation unit 23 (that is, there is an instruction to collect the measurement data Dr according to the latest collection data date / time information D1b acquired from the measurement data recording device 1). (Step 51), the control unit 26 measures the corresponding measurement data Dr (in this example, measurement data Dr recorded following the measurement data Dr specified based on the latest collection data date information D1b). The data is collected from the data recording device 1 (step 52). Specifically, the control unit 26 controls the communication unit 21 to request transmission of the measurement data Dr recorded following the measurement data Dr specified based on the latest collected data date / time information D1b. And the collection device identification code D2a stored in the storage unit 22 are transmitted.

  In response to this, in the measurement data recording device 1, the measurement data Dr recorded after the recording of the measurement data Dr corresponding to the latest collection data date / time information D1b, that is, the number (data number) corresponding to the latest collection data number information D1c. Next, the measurement data Dr of the number (data number) subsequent to is read from the storage unit 22 and the communication unit 15 is controlled to be transmitted to the measurement data collection device 2. Further, the control unit 16 corresponds to the measurement data Dr transmitted to the measurement data collection device 2 (the measurement data Dr most recently collected by the measurement data collection device 2) and the latest collection data date / time information D1b and the latest collection data. The number information D1c is updated, and the collection device information D1d is updated in correspondence with the collection device identification code D2a of the measurement data collection device 2 that collected the measurement data Dr.

  In the measurement data collection device 2, the control unit 26 stores the measurement data Dr transmitted from the measurement data recording device 1 and received by the communication unit 21 (measurement data Dr collected from the measurement data recording device 1). Remember me. Further, the control unit 26 updates the recording device information D2b to the recording device identification code D1a (individual information) acquired from the measurement data recording device 1 from which the measurement data Dr has been collected, and also collects the measurement data collected from the measurement data recording device 1. The individual latest collection data date / time information D2c and the individual latest collection data number information D2d for the measurement data recording apparatus 1 that collected the latest measurement data Dr out of Dr are updated (step 46), and this measurement data collection processing 40 is performed. finish.

  Further, after the message “Do you want to collect data excluding measurement data already collected by another collection device?” Is displayed (step 50) and the cancel switch of the operation unit 23 is operated by the user (step 50) Step 51), for example, the control unit 26 outputs a buzzer sound from a speaker (not shown), and “does this collection device collect only unrecovered measurement data? A message “all collected measurement data is collected” is displayed on the display unit 24 (step 53). At this time, when the user operates the OK switch of the operation unit 23 (that is, there is an instruction to collect the measurement data Dr according to the individual latest collection data date / time information D2c stored in the storage unit 22). (Step 54), the control unit 26 collects only the measurement data Dr that has not been collected by the measurement data collection device 2 from the measurement data recording device 1 (Step 55). Specifically, the control unit 26 controls the communication unit 21 to request transmission of the measurement data Dr recorded following the measurement data Dr specified based on the individual latest collection data date / time information D2c. S2 and the collection device identification code D2a stored in the storage unit 22 are transmitted.

  In response to this, the measurement data recording device 1 measures the measurement data Dr requested by the transmission request signal S2 (in this example, all the measurements that have not been collected by the measurement data collection device 2 that has transmitted the transmission request signal S2). The data Dr) is read from the storage unit 22 and the communication unit 15 is controlled to be transmitted to the measurement data collection device 2. In this case, in the measurement system 100, the measurement data recording device 1 defines a plurality of ring buffer storage areas in the storage unit 12, and erases the measurement data Dr even if the measurement data collection device 2 completes the collection. The structure which does not do is adopted. Accordingly, since the measurement data Dr that has been collected by the measurement data collection device 2 other than the measurement data collection device 2 that has transmitted the transmission request signal S2 is stored in the storage unit 12, the measurement data that has transmitted the transmission request signal S2 is stored. It is possible to reliably transmit unrecovered measurement data Dr to the recovery device 2.

  Further, the control unit 16 adds the latest collection data date / time information D1b and the latest collection data number information D1c to the measurement data Dr (measurement data Dr collected latest by the measurement data collection apparatus 2) transmitted to the measurement data collection apparatus 2. And the collection device information D1d is updated to the collection device identification code D2a of the measurement data collection device 2 that collected the measurement data Dr. Furthermore, in the measurement data collection device 2, the control unit 26 stores the measurement data Dr transmitted from the measurement data recording device 1 and received by the communication unit 21 (measurement data Dr collected from the measurement data recording device 1). Remember me. Further, the control unit 26 updates the recording device information D2b to the recording device identification code D1a acquired from the measurement data recording device 1 from which the measurement data Dr has been collected, and among the measurement data Dr collected from the measurement data recording device 1. The individual latest collection data date / time information D2c and the individual latest collection data number information D2d for the measurement data recording apparatus 1 that collected the latest measurement data Dr are updated (step 46), and the measurement data collection process 40 is terminated. )

  In addition, after displaying the message, “Will this collection device collect only uncollected measurement data? In case of cancellation, all measurement data recorded in the recording device will be collected.” 53) When the cancel switch of the operation unit 23 is operated by the user, the control unit 26 collects all the measurement data Dr recorded in the measurement data recording device 1 (step 45). Specifically, the control unit 26 controls the communication unit 21 to send a transmission request signal S2 for requesting transmission of all measurement data Dr recorded to the measurement data recording device 1 and the storage unit 22. The stored collection device identification code D2a is transmitted.

  In response to this, in the measurement data recording device 1, the control unit 16 reads out all the measurement data Dr stored in each storage area of the storage unit 22 and controls the communication unit 15 to measure the measurement data collection device. 2 is transmitted. Further, the control unit 16 adds the latest collection data date / time information D1b and the latest collection data number information D1c to the measurement data Dr (measurement data Dr collected latest by the measurement data collection apparatus 2) transmitted to the measurement data collection apparatus 2. And the collection device information D1d is updated to the collection device identification code D2a of the measurement data collection device 2 that collected the measurement data Dr.

  In the measurement data collection device 2, the control unit 26 stores the measurement data Dr transmitted from the measurement data recording device 1 and received by the communication unit 21 (measurement data Dr collected from the measurement data recording device 1). Remember me. Further, the control unit 26 updates the recording device information D2b to the recording device identification code D1a acquired from the measurement data recording device 1 from which the measurement data Dr has been collected, and among the measurement data Dr collected from the measurement data recording device 1. The individual latest collection data date / time information D2c and the individual latest collection data number information D2d for the measurement data recording apparatus 1 that collected the latest measurement data Dr are updated (step 46), and the measurement data collection process 40 is terminated.

  On the other hand, when the measurement data collection device 2 that has recently collected the measurement data Dr from the measurement data recording device 1 that is attempting to collect the measurement data Dr by the measurement data collection process 40 is itself (the device itself has the measurement data Dr up-to-date). (When it is a collected device) (step 47), the control unit 26, the contents of the latest collection data date information D1b acquired from the measurement data recording device 1 and the individual latest collection data date and time for the measurement data recording device 1 It is determined whether or not the contents of the information D2c match (whether the latest collection date and time match between the measurement data recording device 1 and the measurement data collection device 2) (step 56). At this time, when the latest collection date / time does not match due to damage or recording failure of either the latest collection data date / time information D1b or the individual latest collection data date / time information D2c, the control unit 26, as an example, Output a buzzer sound and display the message “The management information of this recovery device does not match the management information of the recording device from which the measurement data is to be recovered. Are you sure you want to continue the recovery process?” (Step 57).

  At this time, when the cancel switch of the operation unit 23 is operated by the user (when there is no collection execution instruction) (step 58), the control unit 26 ends the measurement data collection processing 40. Further, when the user operates the OK switch of the operation unit 23 (when a collection execution instruction is issued) (step 58), the control unit 26 outputs a buzzer sound from a speaker (not shown) as an example. At the same time, a message “Do you want to collect data excluding the measurement data already collected by another collection device?” Is displayed on the display unit 24 (step 50). Note that the processing subsequent to the display of this message is the same as the series of processing described above, and the description thereof is omitted.

  In addition, when the contents of the latest collection data date / time information D1b acquired from the measurement data recording apparatus 1 and the contents of the individual latest collection data date / time information D2c for the measurement data recording apparatus 1 match (measurement data recording apparatus 1 and measurement When the latest collection date and time coincides with the data collection device 2 (step 56), the control unit 26 controls the corresponding measurement data Dr (in this example, the latest collection data date information D1b and the individual latest collection data date information D2c). The measurement data Dr recorded after the measurement data Dr specified based on the above is collected from the measurement data recording device 1 (step 52), and the measurement data collection process 40 is terminated. The collection of the measurement data Dr and the update of various information executed thereafter (step 46) are the same as the series of processes described above, and the description thereof is omitted.

  As described above, in the measurement system 100, the measurement data Dr is collected from the measurement data recording device 1 in various forms according to the usage state of the measurement data recording device 1 and the measurement data collection device 2 and the will of the user. The The measurement data Dr collected by the measurement data collection device 2 is transferred to the personal computer 3 via the USB cable, and various analysis processes are executed in the personal computer 3.

  Next, an example of recording and collecting measurement data Dr using two unused measurement data recording devices 1A and 1B and two unused measurement data collection devices 2A and 2B will be described. The usage method of the measurement system 100 will be described more specifically with reference to FIG. Note that the setting of measurement conditions for the measurement data recording devices 1A and 1B and the installation of the measurement data recording devices 1A and 1B at the measurement locations have already been completed, and the measurement data Dr is recorded by the measurement data recording devices 1A and 1B.
