BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. FIG. 1 is a conceptual diagram of an embodiment of the present invention.

If the remote control application program 10 (for example, the known remote control software described above) is installed in the PC 1, various icons 11a are displayed on the display 11 of the PC 1 during the execution of the program 10. Can be displayed and the window 11b can be opened. In one embodiment of the invention, the operator
, A desired command for the electronic measuring instrument, such as a setting command for setting the operation panel of the electronic measuring instrument (command C written in the operation definition command area 33 in FIG. 2).
1, C2, etc.) can be described by text data.

The operator writes a command in the window 11b, and then the operation start switch 31 (see FIG. 2).
When is turned on, the command is sent to the electronic measuring instrument 2,
Will be executed.

According to this embodiment, the operator does not have to write the command in the application program 10 as in the conventional case, but can simply write the command in the window 11b, and the remote control software can be created. It will be easier.

The function of this embodiment will be described in more detail below. FIG. 2 is a block diagram showing a schematic function of this embodiment.

In FIG. 2, the PC 1 has a readable / writable memory 22 composed of a RAM or the like, a non-rewritable memory 23 at the time of execution, and a rewritable memory 24 composed of a RAM or the like. According to the application program 10, an operation start switch (S) 31, a state definition data area (D) 32, and an operation definition command area (C) 33 are defined. The operator launches and operates the application program 10 on the PC 1 to operate the operation start switch (S) 31, the state definition data area (D) 32, and the operation definition command area (C) on the display 11. Three
3 can be displayed as appropriate. The control processing unit 21 is a control program stored in the non-executable rewriting memory 23, and its operation will be described later with reference to FIG. The rewritable memory 24 provides a reception data temporary storage area (O) 34. The device control program 41 can be stored in the non-runtime rewritable memory 23, and its function is to send and receive commands, data, etc. for controlling the electronic measuring instrument 52.

Next, the interface 51 is a GP-IB.
(ANSI / IEEE Std488-1978 standard)
Signal conversion and the like between C1 and the electronic measuring instrument 52 are performed. The electronic measuring instrument 52 is an electronic measuring instrument such as a digital oscilloscope and has, for example, a waveform data memory 52a, an operation panel 52b and the like.

In the present invention, the operation definition command area (C) for inputting the basic remote control function and the remote control procedure.
33, that is, the window 11b and the window 11b
The ability to interpret the data entered in b was included in a single software component.

Next, referring to the flowchart of FIG.
The operation of this embodiment, mainly the operation of the control processing unit 21, will be described.

In step S1, the control processing section 21 determines whether or not the status definition data, for example, the command delimiter code D1 and the device address D2 are set in the status definition data area (D) 32. In step S2, the control processing unit 21 determines whether or not a command to be operated, for example, a setting command C1, a device status inquiry command C2, or a waveform transfer command C3 is written in the operation definition command area (C) 33. do. Next, in step S3, it is determined whether or not the operation starting switch (S) 31 is set to true, that is, whether or not an operation start instruction is given.

The operator performs the setting operation or the writing operation in steps S1 to S3 on the PC 1. In particular, since the command to be operated, for example, the setting command C1, the device status inquiry command C2, or the waveform transfer command C3 need only be written as text data in the window 11b shown in FIG. Does not need to be familiar with the contents of the application program 10, and it becomes possible to create remote control software for an electronic measuring instrument by a simple operation and even by a beginner.

When the determinations in steps S1 to S3 are affirmative, the process proceeds to step S4, in which the control processing section 21 interprets the command C1 etc. written in the operation definition command area (C) 33, and the last step. A command delimiter code D1 is attached to and the command is output to the electronic measuring device identified by the device address D2. An example of the signal form in that case is "output command <device address>" ^* IDN? <Delimiter code> ””. Here, the "output command" is defined by the device control program 41, and is a command for transmitting the code "" to the electronic measuring instrument 52 via the interface 51. Further, <device address> represents the device address D2, and is ““ ^* IDN? Represents a command for inquiring the device name, and <delimiter code> represents the command delimiter code D1.

In step S5, it is determined whether the command is the setting command C1, the device status inquiry command C2, or the waveform transfer command C3. When the setting command C1, the device status inquiry command C2 is sent to step S6. When the waveform transfer command C3, the process proceeds to step S7.

In step S6, the operation panel of the electronic measuring instrument 52 is set in response to the setting command C1. In step S7, in response to the device status inquiry command C2,
Read the setting contents of the operation panel of the electronic measuring instrument 52,
The received data is stored in the memory area O1 of the temporary storage area (O). Further, in step S8, the content of the waveform data memory 52a of the electronic measuring instrument 52 is read and stored in the memory area O2. In step S9, the application program 10 performs post-processing such as display of setting contents and waveform display based on the contents read from the electronic measuring instrument 52.

In step S10, it is judged whether or not the processing for the last command of the commands written in the operation definition command area (C) 33 is completed. When this determination is negative, the process returns to step S4 and the processing of the next command is executed. If the determination in step S10 becomes affirmative and the process proceeds to step S11,
In 11, it is judged whether or not all the controls of the electronic measuring device are completed. If the judgment is negative, step S2
Then, it is judged whether or not a command to be newly operated is written in the operation definition command area (C). Then, the above-mentioned processing is repeated. If the determination in step S11 is affirmative, the series of processes described above ends.

As described above, according to this embodiment, the operator should write a command in the operation definition command area (in the window) in advance when incorporating the remote control software of the electronic measuring instrument into the application program. It is not necessary to know the control procedure of the device or the control method thereof.

[0024]

As is apparent from the above description, according to the present invention, the desired remote control software can be created only by writing the desired remote control function in the window. The person does not have to write a procedure in the application program that is troublesome and requires specialized knowledge.
