Next, the operation of this embodiment will be described with reference to the flow charts shown in FIGS.

When the host computer 2 executes the process of the flowchart shown in FIG. 7 and receives an interrupt signal during the process,
The processing of the flowchart shown in FIG. 8 is executed.

First, in the flowchart shown in FIG. 7, it is determined whether the mode is the setting mode or the working mode. If it is the setting mode, then it is determined whether the part number is input from the keyboard 26. If the part number is entered,
The part number is registered in the measurement data storage unit 24A and the measurement information storage unit 24B. Then, it is determined whether the process number has been input. If the process number is input, the process number is registered in the measurement data storage unit 24A and the measurement information storage unit 24B. Finally, it is determined whether measurement information such as measurement items, reference values, tolerances, control limits, drawing information, and measurement procedure information has been input. If these are input, the measurement information is stored in the measurement information storage unit 24.
Register with B. In this way, when the measurement information is set for each part number and process number, the measurement information is sequentially registered in the measurement information storage unit 24B for each part number and each process number.

On the other hand, in the work mode, subsequently, the process corresponding to the pressed key is executed. For example, the inspection table is created and statistical processing is executed.

If an interrupt signal is received during these processes,
As shown in the flowchart of FIG. 8, it is sequentially determined whether the received signal is a measurement information request signal, a measurement data request signal, or a measurement data transmission signal. If it is a measurement information request signal, the measurement information specified by the part number and the process number included in the measurement information request signal is continuously output from the measurement information storage unit 24B, and the measurement information is requested through the controllers 1 ₁ to 1 _n. The signals are transmitted to the terminals 3 ₂₁ , 3 _{22 to} 3 _n1 , 3 _n2 that transmitted the signals.

Further, if it is a measurement data request signal, the measurement data specified by the part number and the process number included in the measurement data request signal is read from the measurement data storage unit 24A, and the measured data is read through the controllers 1 ₁ to 1 _n. Terminals 3 ₂₁ , 3 _{22 to} 3 _n1 , 3 that have transmitted the request signal
Send to _n2 .

If it is a measurement data transmission signal, the terminal 3 ₂₁ ,
The measurement data transmitted from 3 _{22 to} 3 _n1 and 3 _n2 are received through the controllers 1 ₁ to 1 _{n and} stored in the measurement data storage unit 24A of the RAM 24 for each part number and each process number.

Each terminal _{3 21, 3 22 ~3 n1,} 3 n2, executes the processing of the flowchart shown in FIG. 9. First, it is determined whether the part number is input from the keyboard 36. If the part number is input, the part number is registered in the measurement data storage unit 34A and the measurement information storage unit 34B. Then, it is determined whether the process number has been input. If the process number is input, the process number is registered in the measurement data storage unit 34A and the measurement information storage unit 34B. Then, it is determined whether the lot number has been entered. If the lot number is input, the lot number is registered in the measurement data storage unit 34A.

Then, it is determined whether to request the measurement information from the host computer 2. When requesting the measurement information to the host computer 2, a measurement information request signal including a part number and a process number is transmitted to the host computer 2 through the controllers 1 ₁ to 1 _n , and then the measurement information request signal is sent. The measurement information transmitted from the host computer 2 is received and stored in the measurement information storage unit 34B. After the reception is completed, the measurement information stored in the measurement information storage unit 34B is sequentially displayed on the display unit 37, and the measurement data measured by the measuring unit 40 according to the display is stored in the measurement data storage unit 34A. After the measurement is completed, these measurement data are transmitted to the host computer 2 through the controllers 1 ₁ to 1 _n . If the measurement is not continued or if it is not a new measurement, the process ends.

On the other hand, when the measurement information is not requested from the host computer 2, it is subsequently determined whether or not the measurement information is set. When setting the measurement information, it is subsequently determined whether or not the measurement information, such as the measurement item, the reference value, the tolerance, the control limit value, the drawing information and the measurement procedure information, is input. If these are input, the measurement information is registered in the measurement information storage unit 34B, and then the measurement is performed in the same manner as described above. After the measurement is completed, the measurement data and the measurement information are transmitted to the host computer 2 through the controllers 1 ₁ to 1 _n .

In addition, when requesting any measurement data stored in the host computer 2, a measurement data request signal including a part number and a process number is sent to the host computer 2.
To the measurement data storage unit 34, the host computer 2 sends the measurement data specified by the part number and the process number.
Let A remember. The measurement data stored in the measurement data storage unit 34A can be output from the display 37 and the printer 38.

Therefore, according to the present embodiment, the measurement information is stored in the measurement information storage unit 24B of the host computer 2 for each part number, and the measurement information is stored in each of the terminals 3 ₂₁ , 3 _{22 to} 3 _n1 , 3 _n2 . Since the measurement information can be read out, that is, the measurement information does not have to be set in each terminal as in the conventional case, the measurement information setting operation can be efficiently performed.

In particular, since the measurement information includes the drawing information, anyone can perform the measurement work accurately without any doubt.

Further, in the host computer 2, each terminal 3 ₂₁ , 3
_{In a} state where communication is not made with _{22 to} 3 _n1 and 3 _n2 , it is possible to perform other work, for example, creation of an inspection table and statistical processing, so that work efficiency can be significantly improved. Moreover, in the course of the process, if there is the terminal _{3 21, 3 22 ~3 n1,} 3 n2 from the measurement information or measurement data request or transmission interrupt the measurement data,
Since the interrupt process is prioritized, each terminal 3 ₂₁ , 3
The waiting time of _{22 to} 3 _n1 and 3 _n2 can be reduced.

Further, in each of the terminal _{3 21, 3 22 ~3 n1,} 3 n2, since it is possible to read the measured data stored in the host computer 2, for example, checking the measurement data of the measurement data and post-process of the previous step You can This can contribute to quality improvement because the processing status of the front and rear processes can be checked at any time.

[Effects of the Invention] As described above, according to the present invention, the measurement information is stored in advance in the storage means of the host computer for each part number, and each terminal can read the measurement information. That is, since it is not necessary to set the measurement information at each terminal as in the conventional case, the measurement information setting operation can be efficiently performed.
