Abstract

PURPOSE: To diagnose whether sound volume setting can be normally performed to a sound volume control part by a software or not according to a diagnostic program and to display the diagnosed result. CONSTITUTION: When a user instructs the execution of a software sound volume diagnostic program 32, a software sound volume setting program 31 sets a sound volume value to a sound volume control part 2, sound volume data are sent out and outputted from a speaker 1, and the set value is stored in a set value saving area 4. Concerning the software sound volume setting program 31, the set value is read from the sound volume control part 2, and the saved value stored in the set value saving area 4 and the read value from the sound volume control part 2 are reported to the software sound volume diagnostic program 32. When the compared result of the saved value and the read value shows coincidence, the software sound volume diagnostic program 32 reports the set value, read value and normal state to a display device 5 but when the compared result of the saved value and read value shows non-matching, the set value, read value and abnormal state are reported to the display device 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound volume control unit diagnosis system, and more particularly to a sound volume control unit diagnosis system for diagnosing a data processing device equipped with a sound volume control unit by software with a diagnosis program.

[0002]

2. Description of the Related Art Conventionally, in this type of data processing device, it has not been confirmed whether or not the volume can be normally set by software to the volume controller.

[0003]

In this conventional data processing apparatus, the volume control unit is shipped without checking whether the volume can be normally set by software.

Therefore, there is a problem in that the data processing device, which cannot normally set the volume to the volume control section by software, is shipped as a good product.

An object of the present invention is to provide a sound volume control unit diagnostic system for diagnosing whether or not sound volume can be normally set by software for a sound volume control unit by a diagnostic program and displaying the diagnosis result. To do.

[0006]

According to the present invention, a speaker, a volume controller for setting the volume of the output of the speaker by an input / output command from software, and data processing operable by a program in a storage medium. A diagnostic program for diagnosing the volume control unit of the device, and a display device for displaying a diagnostic result by the diagnostic program, the diagnostic program performing a software volume diagnostic, and a software volume input / output. A software volume setting program for setting, and a software volume state notifying unit for notifying a set value of the software volume, a read value from the volume control unit, and a normal state and an abnormal state of the volume control unit. It is possible to obtain a sound volume control unit diagnostic method.

The diagnostic program inputs / outputs a volume value to / from the volume control section by software and saves the set value in a save area, and the setting of the software volume from the volume control section. When the second step of reading a value, the third step of comparing the saved value of the first step with the read value of the second step, and the comparison result of the third step are the same. Includes a fourth step of notifying the display device of the set value, the read value and the normal state, and notifying the display device of the set value, the read value and the abnormal state when they do not match. A volume control unit diagnostic method characterized by the above is obtained.

[0008]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a data processing apparatus showing an embodiment of the present invention, and FIG. 2 is a flow chart of diagnostic processing in this embodiment.

Referring to FIG. 1, a speaker 1 is used in this embodiment.
And a sound volume control unit 2 for setting the sound volume of the output of the speaker 1 by an input / output command from the software, and a sound volume control unit 2 in a data processing device operable by a program of a storage medium (floppy disk, hard disk, etc.). The diagnostic program 3 for executing the diagnostic program 3, the setting value saving area 4 for saving the software volume setting value when the diagnostic program 3 is executed, and the display device 5 for displaying the diagnostic result by the diagnostic program 3.

The diagnostic program 3 is a software volume diagnostic program 32 for diagnosing software volume.
And a software volume setting program 31 for performing input / output setting of software volume, and a software volume state notifying means for notifying a software volume setting value, a read value from the volume control unit 2, and a normal state and an abnormal state of the volume control unit 2. And 33.

Next, the operation of this embodiment will be described with reference to FIG.

When the software volume diagnostic program 32 is executed according to the user's instruction (Yes in step S201), the software volume setting program 31 sets the volume value in the volume controller 2 (S202), and the volume controller 2 The volume data is sent out and output from the speaker 1, and the software volume setting program 31 stores the volume setting value in the setting value saving area 4.

Thereafter, the software volume setting program 31 reads out the set value from the volume controller 2 (S20).
3), the save value stored in the set value save area 4 and S
The software volume diagnostic program 32 is notified of the read value read in 203 (S204).

Then, if the comparison result of the volume saving value and the read value is matched (Yes in S205), the software volume diagnostic program 32 sets the set value, the read value, and the volume control unit 2.
The normal state of No. 2 is notified to the display device 5 (S206), and if the comparison result of the saved value and the read value does not match (No in S205), the set value, the read value, and the abnormal state of the volume control unit 2 are displayed. The display device 5 is notified (S207).

Therefore, the display device 5 includes the volume control unit 2
The normal condition or abnormal condition of is displayed and the process ends. If No in S201, that is, if the software volume diagnostic program is not being executed, the process ends.

In this embodiment, the volume actually set by the volume controller 2 can be confirmed by the speaker 1.

[0018]

As described above, the present invention provides a speaker, a volume controller for setting the volume of the speaker output by an input / output command from software, and a data processing device operable by a program in a storage medium. A diagnostic program for diagnosing the volume control unit and a display device for displaying the diagnostic result by the diagnostic program are provided. The diagnostic program is a software volume diagnostic program for diagnosing software volume, and a software volume setting for performing input / output setting of software volume. By including a program and a set value of the software volume, a read value from the volume control unit, and a software volume state notifying unit for notifying a normal state and an abnormal state of the volume control unit. When the volume value is set to input / output by software in the control unit, The first step of saving the set value in the save area, the second step of reading the set value of the software sound volume from the sound volume control unit, the comparison of the saved value of the first step and the read value of the second step When the comparison result of the third step and the comparison result of the third step match, the set value, the read value, and the normal state are notified to the display device, and when they do not match, the set value, the read value, and the abnormal state are displayed. By providing the fourth step of notifying the display device of the above, it is possible to find a defect in the volume control unit before shipping.
