In FIG. 6, the measurement data collection device A first acquires the first and second detection signals from the first and second

connection detection units

17a and 17b by the D control processing unit 15 (S11). In the present embodiment, ten first to tenth detection signals are acquired from ten first to tenth connection detectors 17a-1 to 17a-10, respectively. Ten 2-1 to 2-10 detection signals are acquired from the 2-1 to 2-10 connection detection units 17b-1 to 17b-10, respectively.

Subsequently, the measurement data collection device A sets 10 sets based on the first and second detection signals of the first and second

connection detection units

17a and 17b acquired in the process S11 by the D control processing unit 15. It is determined whether or not a plurality of measurement units S are mixedly connected to the first and

second connection connectors

11a and 11b (S12).

As a result of this determination, the first detection signal is a signal representing the connection of the measurement unit S (in the present embodiment, all or part of the first to tenth detection signals are Hi). When the second detection signal is a signal representing disconnection of the measurement unit S (in the present embodiment, when all of the 2-1st to 2nd-10 detection signals are Hi), the 11th connection is established. When one or more measurement units S are connected to only the connector 11a and it is determined that they are not mixed (No), and as a result of the determination, the second detection signal is a signal representing the connection of the measurement units S ( In the present embodiment, all or part of the 2-1st to 2nd-10th detection signals are Low), and the first detection signal is a signal representing disconnection of the measurement unit S ( In the present embodiment, there is no 1-1.

In the process S13, the warning unit 153 outputs a warning indicating that a plurality of interface standards are mixed and used. Thus, in the present embodiment, for example, a warning message such as “the interface standard is unified and each measurement unit is not connected” is displayed on the display surface of the display unit 13.

In the process S14, the stopping unit 154 causes the eleventh and twenty-

first interface units

12a and 12b to stop communication. More specifically, for example, even if the operation unit 14 receives a measurement start instruction from the user, the eleventh and twenty-

first interface units

12a and 12b do not communicate measurement data. As described above, in the process S14, the stopping unit 154 may cause the data collection control unit 152 to stop the process of collecting measurement data. In this case, more specifically, even if the operation unit 14 receives an instruction to start measurement from the user, the data collection control unit 152 does not execute the process of collecting measurement data. Once the mix of connections is resolved, measurements can be made.

In the present embodiment, the measurement data collection apparatus A operates in this manner in connection detection processing for detecting the connection of the measurement unit S. Therefore, the measurement data collection device A according to the present embodiment can use the interface standards (the eleventh and 21st IF

sections

12a and 12b) shown in Table 1 with respect to the 11th and

21st connection connectors

11a and 11b. ing.

(Measurement data collection process)
In measurement data collection processing for collecting measurement data from the measurement unit S, first, the user (operator) first uses one or more measurement units S, or the eleventh connection connector 11a when using the USB standard, or RS- When using the 232C standard, connection is made to the 21st connection connector 11b. When connecting a plurality of measurement units S, the user connects the plurality of measurement units S to the measurement data collection device A so that the USB standard and the RS-232C standard are not mixed. When the plurality of measurement units S are connected by mixing the standards, a warning message is displayed from the display unit 13 by the above-described operation described with reference to FIG. Here, when the normal measurement mode is used, either the USB standard or the RS-232C standard can be used, but when the trigger measurement mode is used, the user can measure the plurality of measurement units S by RS-232C. In order to use the standard, a plurality of measurement units S are connected to the 21st connection connector 11b.

Subsequently, the user inputs one of the normal measurement mode and the trigger measurement mode from the operation unit 14. When the measurement unit S is connected only to the eleventh connection connector 11a, this process of inputting an instruction of this measurement mode can be omitted, and the normal measurement mode may be automatically set. In addition, in the case where the measurement unit S is connected only to the eleventh connection connector 11a and the input of the trigger measurement mode is received by the operation unit 14, the trigger measurement mode can not be set (selected). The measurement data collection apparatus A may be configured to display a warning message on the display unit 13. In addition, when the measurement unit S is connected only to the 21st connection connector 11b, this process of inputting an instruction of this measurement mode may be omitted, and the trigger measurement mode may be set automatically.

Then, the user inputs an instruction to start measurement from the operation unit 14. In FIG. 7, when the measurement control instruction is received by the operation unit 14 by the D control processing unit 15 (S21), the measurement data collection device A determines whether the data collection is stopped by the stop unit 154 (S21) S22). As a result of the determination, when the data collection is stopped (Yes), the D control processing unit 15 ends the present process. In this case, the D control processing unit 15 displays, for example, a message such as “Preparation for data collection is not completed. Please confirm peripheral devices.” On the display unit 13 and then this process. You may quit. On the other hand, if it is determined that the data collection is not stopped as a result of the determination (No), the D-control processing unit 15 next executes a process S23.

In the process S23, the measurement data collection device A determines the operation mode by the data collection control unit 152 of the D control processing unit 15. As a result of the determination, if the operation mode is the normal measurement mode (normal measurement mode), the data collection control unit 152 sequentially performs the processes of the process S24 and the process S25, and then performs this process. finish. On the other hand, if it is determined that the operation mode is the trigger measurement mode (trigger measurement mode) as a result of the determination, the data collection control unit 152 sequentially performs each process of the process S26 and the process S27. End the process.

In the process S24, the data collection control unit 152 detects the connection of the measurement unit S by the first and second

connection detection units

17a and 17b. The eleventh and 21st IF units 12a of the eleventh and

21st connection connectors

11a and 11b , 12 b output (send) an instruction to start measurement to the measurement unit S. More specifically, when the data collection control unit 152 detects the connection of the measurement unit S to the eleventh connection connector 11a by the first and second

connection detection units

17a and 17b, the eleventh IF unit 12a detects the connection of the measurement unit S. An instruction to start measurement is output to the measurement unit S according to 1 interface standard (in this embodiment, USB standard). In the data communication of the USB standard, in the present embodiment, for example, the signal “0” and the signal “1” are represented by the NRZI (Non Return to Zero Inversion) method, and on the transmission side, the differential pair (D− No. No. 2 pin and differential pair (D +) No. Inverting the potential between pin 3 generates a signal “0”, holding the potential (not inverting) generates a signal “1”, and on the receiving side, a differential pair (D -) No. No. 2 pin and differential pair (D +) No. When the potential between pin 3 is inverted, this means signal "0", and when the potential is held (not inverted), this means signal "1". Alternatively, when the data collection control unit 152 detects the connection of the measurement unit S to the 21st connection connector 11b by the first and second

connection detection units

17a and 17b, the second interface standard (the 11th IF unit 12b) In this embodiment, an instruction to start measurement is output to the measurement unit S by the RS-232C standard). In the data communication of RS-232C standard, in the mini-DIN 8-pin connector of the present embodiment, No. 1 is used. Pin 4 is used as RxD (Receive Data), and No. 4 pin is used. Pin 6 is used as RTS (Request to Send). Pin 7 is used as TxD (Transmit Data). Eight pins are used as CTS (Clear to Send).

When receiving the instruction to start the measurement, the measurement unit S measures the measurement target, and outputs (sends) measurement data obtained by the measurement to the measurement data collection device A. For example, when three first to third measurement units S-1 to S-3 are connected to the measurement data collection device A, the first measurement unit S-1 receives the instruction to start the measurement. The measurement target is measured at an appropriate timing of the first measurement unit S-1 and the measurement data is output to the measurement data collection device A, and the second measurement unit S-2 receives the instruction to start the measurement. The measurement target is measured at an appropriate timing of the second measurement unit S-2 and the measurement data is output to the measurement data collection device A, and the third measurement unit S-3 instructs the start of the measurement. When the third measurement unit S-3 receives the measurement data, the measurement target is measured at an appropriate timing of the third measurement unit S-3, and the measurement data is output to the measurement data collection device A.

In processing S25 following the processing S24, the measurement data collection device A acquires and stores the measurement data output (sent) from the measurement unit S by the data collection control unit 152 of the D control processing unit 15, This process ends. The measurement data collection apparatus A may end the present processing after performing appropriate processing such as displaying the acquired measurement data on the display unit 13 or the like.

On the other hand, in the process S26, the data collection control unit 152 outputs the trigger signal to the measurement unit S at the 21st IF unit 12b of the 21st connection connector 11b whose connection of the measurement unit S is detected by the second connection detection unit 17b ). In the data communication of RS-232C standard, in the mini-DIN 8-pin connector of the present embodiment, No. 1 is used. Pin 1 is used as Trigger IN. Pin 2 is used as Trigger OUT.

When the trigger signal is received, the measurement unit S measures the measurement target at the measurement timing synchronized with the trigger signal, and outputs (transmits) the measurement data obtained by the measurement to the measurement data collection device A. For example, when three first to third measurement units S-1 to S-3 are connected to the measurement data collection device A, the first to third measurement units S-1 to S-3 can When the trigger signal is received, the measurement target is measured at measurement timings synchronized with each other by the trigger signal. Then, the first measurement unit S-1 outputs the measurement data to the measurement data collection device A, and the second measurement unit S-2 outputs the measurement data to the measurement data collection device A, and The measurement unit S-3 outputs the measurement data to the measurement data acquisition device A.

In processing S27 following the processing S26, the measurement data collection device A acquires and stores the measurement data output (sent) from the measurement unit S by the data collection control unit 152 of the D control processing unit 15, This process ends. The measurement data collection apparatus A may end the present processing after performing appropriate processing such as displaying the acquired measurement data on the display unit 13 or the like.

In the present embodiment, the measurement data collection apparatus A operates in this manner with regard to measurement data collection processing for collecting measurement data from the measurement unit S.
