Process 203: The end of all measurement items, that is, the end determination is made. If the required number of parameter set values has not been measured, the result is "No", and the process 200 and subsequent steps are repeated. If the required number has been measured, the operation ends with "Yes".

In the result input of the process 202, even when a measuring instrument that can obtain a plurality of measurement results at the same time is used, only the measurement result of the target measurement item is taken into the internal variable of the program among the taken measurement results. Other measurement results have been discarded.

Therefore, even if the set values of the parameters are the same, the processes 200 to 201 are always repeated when the measurement result of another measurement item is intended.

In the following description, it is premised that a measuring instrument is used which can obtain a plurality of measurement results at the same time when one set value of a parameter is set.

[0015]

Even if the setting values of the parameters are the same, in order to obtain the measurement results of different measurement items, the parameters are reset and the measurement results are fetched. And the measuring time of the measuring instrument becomes long.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a measuring instrument control device for inspecting a mobile phone according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a measuring instrument controller according to an embodiment of the present invention. FIG. 2 is a diagram showing tables stored in the storage device in FIG. 1, and these tables show the relationship between parameters and measurement results. FIG. 3 is a flowchart showing the operation of the measuring instrument control device shown in FIG.

In FIG. 1, the input device 1 is used for inputting an instruction of a set parameter and a set value of the parameter itself. The display device 2 displays the set value of the instructed parameter and is used for inputting the set value of the parameter while confirming the contents. When the measurement item is executed, the parameter setting value and the measurement result are displayed.
The storage device 3 stores the input set values of the parameters and provides the set values of the parameters to the computer 4 when performing the measurement. It also temporarily stores the measurement result read from the measuring instrument 5. The computer 4 reads the input set values of the parameters from the storage device 3. Measuring instrument 5
In order to control the
Give to. A measurement start instruction is given to the measuring instrument 5 and a measurement result is read.

Next, referring to FIGS. 2 and 3, the association between the parameter setting value and the measurement result and the processing procedure will be described.

In the inspection of the mobile phone, a combination of setting values (including non-setting) given in advance for each parameter is provided. In the parameter table 10 of FIG. 2, a plurality of pairs of measurement numbers and data numbers are registered. The measurement number is a number for designating a measurement function which is a combination of one or more measurement items of the measuring instrument 5 and parameter setting values. The computer 4 gives the measurement number to the measuring instrument 5
Then, the measuring instrument 5 executes the corresponding measuring function.
Execution of a measurement function usually yields multiple measurement results.
The data number is a number for designating one necessary measurement result among the measurement results of a plurality of measurement items obtained by executing the measurement function by sending the measurement number to the measuring instrument 5.

In the table shown in FIG. 2, it is assumed that the measurement numbers take values 1 to N and the data numbers take values 1 to M. There is no inconvenience even if the measurement number and data number are entered in a character string that people can easily understand,
In any case, since it is replaced with a numerical value and processed inside the measuring instrument control device, the numerical value will be described here.

In a certain area of the storage device 3, addresses 1 to N are assigned to the flag table, and N + 1 to (M +
1) Address N is assigned to the measurement result table.
A flag indicating execution or non-execution of the measurement function with the measurement number n is written in the address n (1 ≦ n ≦ N) of the flag table. N + n, 2N + n, ... M of the measurement result table 12
The measurement result of each measurement item by the execution of the measurement function with the measurement number n is written in the address N + n in a predetermined order. Parameter table 10 before performing the process shown in FIG.
Enter the data number and measurement number in.

In FIG. 3, the process 100 writes a flag (0) in the flag table 11 at addresses 1 to N as initialization work.

The process 101 sets a flag (1) at the address n (value of 1 to N) indicated by the measurement numbers sequentially read from the parameter table 10 in the flag table 11.

When this process is performed for L measurement numbers, the flag (1) or the flag (0) is written in the addresses 1 to N of the flag table 11.

Here, description will be given using an example shown in FIG.
In process 101, since the measurement numbers of the parameter table 10 of FIG. 4 are 1, 2, 4, 4, and 2, the flag (1) is written in the addresses 1, 2, and 4 of the flag table 11. .

The process 102 is a flag, 1 of the table 11.
The contents are read in order from the address. In the example of FIG. 5, (1)
The flags are read in the order of (1) (0) (1).

The process 103 judges the flag read in the process. If the flag is (0), control is passed to process 104, and if the flag is (1), control is passed to process 200.

The process 104 determines whether or not all the contents of the flag table 11 have been read. If it has not been read, control is passed to process 102, and if it is read, control is passed to process 110.

The process 200 causes the measuring instrument 5 to execute the measuring function for the measuring number having the flag (1).
Set the value of the parameter.

A process 201 controls the measuring instrument 5 to perform measurement.

The process 202 is performed by the measuring instrument 5 by m (1≤m).
The measurement result of ≦ M) is fetched, and the control is transferred to the process 105.

In process 105, the obtained measurement results of the m measurement items are stored in the measurement result table 12 as N + n, 2N +.
Write to an address predetermined by the measurement item of n, ... MN + n (assumed to be the result of executing the measurement function of measurement number n).

Here, description will be made using the example shown in FIG.
Since the process 105 is a process to be executed without fail when the flag is (1), in the case of FIG. 5, the process is executed three times. In the first process 105, the measurement result is input to the row of address 1, that is, addresses 5, 9, 13, 17, and 21. Two
In the process 105 of the first time, the line of address 2, that is, addresses 6 and 1
The measurement result is input to 0, 14, 18, 22. In the last process 105, the row of address 4, that is, addresses 8, 12, 1
The measurement result is input to 6, 20, and 24.

The process 110 is the parameter table 10
Are sequentially read, and the measurement result corresponding to the measurement number n and the data number m is read from the address m × N + n of the measurement result table 12 and stored as the result of the measurement item.

Description will be made with reference to the example of FIG. Process 110
Based on the parameter table 10, the result of address 9 in the first result, the result of address 6 in the second result, 3
The result of address 12 is in the second result and the address of 1 is in the fourth result
The result of No. 6 is read as the measurement result of the result of the address 14 in the fifth result, and is saved as the result of each measurement item.

If the number of measurement numbers input to the parameter table 10 is L, it is necessary to set the parameter L times in order to perform the same measurement with the conventional measuring instrument controller.

In the measuring instrument control device of this embodiment, when the maximum value N of the measurement number is equal to or less than L, the parameter setting can be performed up to N times, which is (L−N) times compared with the conventional measuring instrument control device. Time for parameter setting, measurement, and measurement result input is shortened.

When the maximum value N of measurement numbers is L or more,
The parameter setting is completed up to L times. The number of times of parameter setting, measurement, and measurement result input is reduced by the duplication of measurement numbers input in the parameter table.

Generally, the control time of the measuring instrument, for example, the parameter setting time, the measurement time, and the measurement result acquisition are much longer than the program execution time.

Therefore, the overall processing speed of the measuring instrument control device of the present invention is higher than that of the conventional measuring instrument control device, although
I know it's early.

Further, although the processing contents of the program are complicated in comparison, since the processing itself can be realized by a simple address calculation, the program execution time hardly changes.

[0045]

The measuring device control apparatus and method according to the present invention,
Of course, the measurement results of all the measurement items obtained are stored in the storage device, and the parameter set values are the same. However, when the measurement result of another measurement item is required, the necessary measurement result is read directly from the corresponding storage device without data operation such as search and sort.

Therefore, when a parameter setting value is given and measurement is performed to obtain a measurement result of a certain measurement item, and a measurement result of another measurement item is needed even if the parameter setting value is the same, the parameter is set again. Since it is not necessary to give the set value of and to take the measurement result, the parameter setting time and the measurement time of the measuring instrument can be saved, the execution time of the measurement item can be shortened, and the production throughput can be improved.
