2. Description of the Related Art Conventionally, in measuring a physical quantity of a work such as length measurement, a measuring gauge which detects a measured value as an electric signal by an optical or capacitance type detecting means has been known.
As such a measuring gauge, for example, a main body, a spindle slidably provided on the main body, and a fixed-side detection element fixed to the main body and moving in the same direction in synchronization with sliding of the spindle. 2. Description of the Related Art A digital dial gauge that includes a movable-side detection element and detects an amount of relative movement displacement between both detection elements as an electric signal is known.

An electric signal detected by the digital dial gauge is digitally displayed by directly connecting a display unit to the digital dial gauge, and a relay unit is connected to the digital dial gauge, and an arithmetic operation of a personal computer or the like is performed through the relay unit. The measurement data may be transmitted to the processing means, and the measurement data may be processed by the arithmetic processing means.

Usually, one or two digital dial gauges are connected. When the measurement data from a plurality of digital dial gauges is collected and processed by one arithmetic processing unit, the measurement data is transmitted through a plurality of relay units connected to the arithmetic processing unit.

According to the measurement data processing apparatus having the measurement gauge, the relay unit, and the arithmetic processing means, even if a plurality of measurement gauges are provided for one work to be measured, one arithmetic processing unit is required. Since the processing can be performed simultaneously by the means, the length measurement operation can be reduced.

[0005]

However, in the above-described measurement data processing device, when the measurement gauge and the arithmetic processing means are connected via a plurality of relay units,
All the relay units must be individually connected to the arithmetic processing means, and there are the following problems. In the multi-point simultaneous measurement, the measurement data transmitted from each measurement gauge is collected by the arithmetic processing means. In order to secure a recording area corresponding to each measurement gauge inside the arithmetic processing means, the recording area and the measurement gauge are measured. It is necessary to set an address corresponding to the above.

This address setting is determined by the connection state between the arithmetic processing means and the relay unit, and in which recording area the measurement data of each measurement gauge is stored is determined by a plurality of input / output ports provided in the arithmetic processing means. It depends on which relay unit is connected. Therefore, the address setting depends on the human work of connection between the arithmetic processing means and the relay unit, and there is a problem that the address setting work becomes complicated as the number of measurement gauges installed increases. In addition, if the number of measurement gauges is increased, the number of connection lines between the relay unit and the arithmetic processing means increases, so that the possibility of erroneous connection increases. In this case, the processing means collects appropriate measurement data. There is a problem that can not be performed.

The number of measurement data that can be collected and processed by one arithmetic processing means, that is, the number of measurement gauges that can be connected to one arithmetic processing means is determined by the number of input / output ports provided in the arithmetic processing means and the number of relay units.

Become. Also, since the transmission completion signal is transmitted only to the adjacent relay unit via the transmission line, the other relay units do not erroneously take in the address data.

When the subsequent relay unit 40 receives the transmission completion signal S2, the relay unit 40 transmits the measurement data S1 to the personal computer 60 (see FIG. 5D). When all the measurement data S1 has been transmitted, a transmission identification signal END indicating that the measurement has been completed is transmitted from the data transmission identification line 713 to the personal computer 60, and the measurement is completed (see FIG. 5E). When the transmission identification signal END is sent to the personal computer 60 via the RS232C cable 72, the transmission identification signal END can be transmitted using the transmission line 712 constituting the RS232C cable 72.

Is provided with address transmission means, and sets address data ID1 to ID6 while adding the number of its own digital dial gauge 10 and transmits it to the relay units 20 and 40 at the subsequent stage. Address data ID1 to
6 can be automatically grasped. Therefore, the personal computer 60 only needs to secure a recording area corresponding to the address data ID6 transmitted by the last relay unit 40, and can automate address setting by using spreadsheet software or the like. .

Further, since the measurement data processing apparatus 1 has such a configuration, when a new digital dial gauge 10 is newly added, the end of a plurality of serially connected relay units 20 and 40 is connected to one end. A new relay unit 20 via a cable 71 to the relay unit 40 to be arranged,

Further, since the above-described measurement data processing device 1 is set to automatically set an address, it is not necessary to separately set the address of the recording area of the personal computer 60, and the device can be expanded more easily. Can be.

The address data ID1 is fetched on condition that the relay unit 40 receives the transmission completion signal S2 from the preceding relay unit 20.
The address data ID6 can be transmitted accurately and reliably to the personal computer 60. Further, since the transmission completion signal S2 is transmitted only to the adjacent relay units 20 and 40 via the transmission line 714, the other relay units do not erroneously take in the address data, and the highly reliable address data ID1 ~ 6 can be exchanged.

Further, since the address data IDs 1 to 6 are transmitted to the personal computer 60 via the transmission data line 712 connecting the respective relay units 20 and 40 in parallel, the address data IDs 1 to 6 can be easily transmitted to the personal computer 60.
In addition, since it can be used as a transmission data line 712 for transmitting measurement data at the time of measurement, the structure of a connection line of the measurement data processing device 1 can be simplified. The execution means of the personal computer 60 is configured to operate on condition that the personal computer 60 receives the transmission identification signal S3. Therefore, after the address setting of the personal computer 60 is completed, the measurement data S1 is automatically transmitted. A collection process can be performed, and a series of operations from address setting to measurement start can be further simplified.
