Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a voice level test method for testing the normality of a voice guidance signal generator in an information storage and exchange system equipped with a voice guidance signal generator. .

Prior Art and Problems In an information storage and exchange system in which input operations are performed according to voice guidance, no tests have been conducted on the voice guidance signal generator. This is because if a failure occurs in the voice guidance signal generation unit, the subscriber will not be able to hear the voice guidance, so the subscriber will report the defective voice guidance to the exchange, and the exchange will respond to the voice guidance based on this report. It was possible to discover the location of the failure in the guidance signal generator. Therefore, it was treated as a device that was not subject to regular testing.

However, even if a failure occurs in the voice guidance signal generation unit, if the subscriber does not report it, the switching office will not know that the failure has occurred, and the failure of the information storage and exchange system will become latent. There was a drawback that caused the decline.

OBJECT OF THE INVENTION The present invention provides a system for easily testing the normality of a voice guidance signal generating section through periodic automatic tests or command tests.
The purpose is to prevent potential failures.

Structure of the Invention The present invention provides an information storage and exchange system that includes a voice processing line control unit and a voice guidance signal generation unit, in which a voice guidance signal from the voice guidance signal generation unit is transmitted to the voice processing line during a test. Switch to the control section and add
The voice processing line control unit detects the level of the voice guidance signal to test the normality of the voice guidance signal generation unit, and the voice processing line control unit is used to generate the voice guidance signal. This makes it easy to conduct tests for the parts of the body. Examples will be described in detail below.

Embodiment of the invention FIG. 1 is a block diagram of main parts of an embodiment of the invention.
is an exchange, 2a to 2n are subscribers, 3 is a voice storage processing unit,
Reference numeral 4 designates an audio processing line control section, 5 an audio storage section consisting of a magnetic disk device, etc., and 6 an audio guidance signal generation section. For example, when subscriber 2a sends a message to absent subscriber 2n, voice guidance is connected to voice storage processing section 3 via exchange 1, and voice guidance instructing operation is sent to subscriber 2a from voice guidance signal generation section 6. Sent out. By operating the subscriber 2a according to this voice guidance, the subscriber 2a can
a can store messages for the subscriber 2n in the voice storage section 5.

When the absent subscriber 2n returns and is connected to the voice storage processing section 3 via the exchange 1, the voice guidance from the voice guidance signal generation section 6 is sent to the subscriber 2n. By performing an operation according to the voice guidance, the message stored by the subscriber 2a is played back from the voice storage unit 5 under the control of the voice processing line control unit 4 and sent to the subscriber 2n.

The audio processing line control unit 4 detects the presence or absence of an audio signal during audio storage, and only controls the audio storage unit 5 when there is an audio signal.
Therefore, it is possible to detect whether the voice guidance signal from the voice guidance signal generating section 6 is transmitted at a predetermined level. Therefore,
The voice guidance signal from the voice guidance signal generator 6 is transmitted to the voice processing line controller 4 periodically or by command.
By adding the voice guidance signal to the voice detection section 6, it is determined whether the voice guidance signal is normally sent out or not, and the voice guidance signal generation section 6 is tested.

FIG. 2 is a block diagram of the main parts of the audio storage processing section according to the embodiment of the present invention, in which the same reference numerals as in FIG. 1 indicate the same parts;
．． 8 is a switch section, a is a switching signal during testing, b is a switching signal for switching between sending out a voice guidance signal and sending out a reproduced message, and C is a signal when the voice guidance signal from the voice guidance signal generating section 6 is below a predetermined level. This is an alarm signal sent out.

FIG. 3 is a block diagram of the main parts of the voice guidance signal generation section, and the common control section includes a microprocessor MPU, a read-only memory ROM in which programs are stored, a read-only memory VDROM in which voice data is stored, and various other components. It is composed of a random access memory RAM used for temporary storage of control data, etc., and is connected to the line corresponding units L U O to LUn including the audio output unit via a common bus. The cross-line corresponding section LUO=LUn is the switch 1
It is activated by a control signal d corresponding to control information from the central control unit of the switch unit 7. LO to Ln correspond to a pair of accommodation positions of the exchange 1, and are connected to the exchange 1 via switch sections 7 and 8 shown in FIG. 2, respectively.

The line corresponding section connected to the subscriber via the exchange 1 is activated by the control signal d, and a voice guidance signal is sent from the common control section.

In the case of normal storage and playback transmission of messages from subscribers, the switch section 7 is switched to the dotted line path by the switching signal a, and the exchange and the voice processing line control section 4 are connected, and the The line control unit 4 identifies whether there is sound or no sound by detecting the level of the voice signal from the subscriber, etc.
The silent period is time-compressed and only the voice signal is stored in the audio storage section 5. In addition, the switch section 8 is connected to the audio storage section 5.
When sending a playback message to subscribers from
The route is switched to the route shown by the dotted line, and when the audio guidance signal is to be sent to the subscriber, it is switched to the route shown by the chain line.

When testing the voice guidance signal generator 6, the control signal d sequentially or arbitrarily puts the line corresponding parts into the operating state, and the switching signal a is applied to the switch section 7 connected to the line corresponding part that has become in the operating state. Then, the switch section 7 is switched to the path shown by the chain line.

Thereby, the voice guidance signal from the voice guidance signal generation section 6 is applied to the voice processing line control section 4 via the switch section 7. This voice processing line control unit 4 identifies that the voice guidance generating unit 6 is being tested by the switching signal a, identifies the level of the voice gun dance signal, and if it is below a predetermined level, an alarm signal C Send out.

This alarm signal C is sent to a test stand or the like and recorded.

When one line corresponding section consisting of the lines LO-Ln of the voice gun dance signal generating section 6 is activated and tested, the alarm signal C is sent, and the other line corresponding sections are activated and tested. If it is assumed that the alarm signal C is not sent out at some point and is normal, then it is clear that there is a fault in the line corresponding section when the alarm signal C is sent out. Also, each line correspondence department L U O
- If the alarm signal C is sent out in any case when L U n is tested in the operating state, it is known that a fault has occurred in the common control section.

Testing of the audio guidance signal generator 6 can be performed periodically during low-traffic hours such as at night, or by commands from a test stand, etc.
Even when the voice guidance signal generating section 6 is duplicated, the occurrence of a failure can be detected before a double failure occurs, so reliability can be improved.

As described in detail, the present invention provides an audio processing line control section 4.
