The announcement apparatus includes a key input unit 151, an announcement control unit 152, an A / D conversion unit 153, a silence detection unit 154, A serial / parallel conversion unit 155, a temporary storage unit 156, a guidance message storage unit 157, a parallel / serial conversion unit 158, and an output unit 159.

In this figure, the key input unit 151 includes a guide message recording key for modifying or additionally storing a guidance message used in the exchange, and outputs a key signal corresponding to a user's key operation.

Then, the announcement control unit 152 counts the guidance message number and the time according to the comparison result between the guidance message detection signal level applied based on the guidance message recording key signal from the key input unit 151 and the predetermined silence level A guidance message and a message time corresponding to the message number are read based on a guidance service control signal from an upper processor not shown in the figure, and the message time is read out by the message time read in the corresponding time slot channel Output.

The A / D converter 153 performs PCM modulation on the analog voice signal reproduced from the microphone or the cassette tape under the control of the announcement control unit 152, as digital voice data.

On the other hand, the silence detection unit 154 integrates the serial audio data from the A / D conversion unit 153 for a predetermined time and applies it to the announcement control unit 152 at the guidance message signal level.

The serial / parallel converter 155 converts the digital voice data from the A / D converter 153 into parallel voice data of predetermined bits on the basis of the control from the announcement controller 152, and outputs the parallel voice data.

The temporary storage unit 156 temporarily stores and reads voice data from the serial / parallel converted unit 155 under the control of the announcement control unit 152. [

The guidance message storage unit 157 stores the voice data from the temporary storage unit 155 together with the counted message time from the guidance broadcast control unit 152 in correspondence with the message number from the guidance broadcast control unit 152 Read.

On the other hand, the bottle-serial conversion unit 158 converts the voice data from the guidance message storage unit 157 into serial voice data under the control of the announcement control unit 152 and outputs it.

Finally, the output unit 159 outputs audio data from the p / s converter 158 on the basis of the frame sync signal from the time switch 130 and the reference clock signal under the control of the announcement control unit 152 And outputs it to the time switch 130 via the sub-highway.

Next, a detailed description will be made with reference to the flowchart of FIG. 3, which shows a guide message recording process according to a preferred embodiment of the present invention in an announcement broadcasting apparatus including the above-described components.

First, the operator starts recording the guidance message using the recording key for recording the guidance message of the key input unit 151. [

At this time, if the recording key signal is applied from the key input unit 151 (step 300), the announcement control unit 152 performs silence detection

More specifically, after the operation of the recording key of the key input unit 151, the operator inputs a guidance message at a predetermined interval through the microphone to the input terminal of the A / D conversion unit 153, The cassette tape recorded continuously is reproduced and the guide message to be recorded is successively inputted.

Then, the announcement control unit 152 controls the A / D conversion unit 153 to convert the applied analog voice signal into digital voice data.

At this time, the silence detection unit 154 receives the serial digital voice data, integrates the detection for a predetermined time, and applies the DC level to the announcement control unit 152.

Then, the announcement control unit 152 compares the received guidance message signal level with a previously set silence level (a threshold signal level judged that no voice is present) to determine whether silence is detected (step 302).

At this time, if the detected guide message signal level is greater than a predetermined silence level, that is, if the guidance message is loaded with the actual voice larger than the predetermined silence level, the guidance message is recognized as being started and a predetermined counter Start counting (step 304).

Next, the announcement control unit 152 increments the message number from '0' to '1' in order to automatically assign the message number (step 306).

On the other hand, the serial voice data from the A / D converter 153 is applied to the serial-to-parallel converter 155, and the serial voice data supplied from the serial / parallel converter 155 is divided into a predetermined number of bits Converts it into parallel voice data and outputs it.

Next, the parallel voice data is temporarily stored in the temporary storage unit 156 under the control of the announcement control unit 152, and is read and applied to the guidance message storage unit 157. [

The guidance message storage unit 157 stores the parallel voice data from the temporary storage unit 156 at a corresponding position set corresponding to the increased message number based on the control from the announcement control unit 152 ).

In addition, the silence detection unit 154 integrally detects the signal level of the guide message continuously applied to detect the end time of one guide message, and the announcement control unit 152 continuously detects the silence level, The levels are compared (step 310).

At this time, if the guide message signal level to be applied is larger than a preset silence level, that is, if no silence is detected, the guidance message converted into serial digital voice data is converted into a parallel voice data And stores the received guidance message in the guidance message storage unit 157.

On the other hand, if the guidance message signal level detected in step 310 is less than a predetermined silence level, that is, if recording is detected that is not an actual voice, the controller recognizes that the input of one guidance message is stopped and stops the message time count (Step 312).

Next, the announcement control unit 152 applies the counted message time to the guidance message storage unit 156, and stores the counted message time in the message time corresponding to the increased message number in step 305 (step 314).

Next, the message time count is initialized (step 316) to store the next guidance message to be continuously applied, and the process returns to step 302 to continue the guide message storage process described above.

On the other hand, if the predetermined time period set in the step 302 has elapsed (step 318), if the continuous silence is detected, it is recognized that the input of all the guidance messages is finished and the present routine, which is a continuous storing process of the guidance messages, is terminated.

Meanwhile, when the guide messages are stored in the guide message storage unit 157 for each type, the exchange transmits a corresponding announcement message to the corresponding subscriber's phone according to the situation to perform announcement broadcasting. The explanation is as follows.

First, the announcement control unit 152 reads the guidance message based on the control of the not-shown higher-order processor. First, the guidance message storage unit 157 is controlled to read out the guidance message.

Then, the parallel voice data read out from the guidance message storage unit 157 is converted into serial voice data in the p / s converter 15S, and is then applied to the output unit 159 again.

Next, the output unit 159 outputs the frame synchronization signal from the time switch 130 and the voice data from the P / S converter 158 based on the control of the announcement control unit 152 and the reference clock signal And transmits the counted message time stored in the time slot channel to the time switch 130 via the sub highway cable. Based on the time slot interchange of the time switch 130, the subscriber hears a guidance message to the handset of the telephone Be able to

As described above, according to the present invention, the guide message used in the entire electronic exchange is judged as the signal level of the guidance message to be inputted and stopped to input the guidance message at the time of recording, and the message number and the message time are automatically counted It is possible to provide convenience in that a plurality of guide messages can be recorded continuously and conveniently in a convenient and quick manner.
