  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of an operation console in the first embodiment of the present invention, and FIG. 2 shows an operation for carrying out a report from an earthquake early warning terminal in the first embodiment of the present invention. It is a timing chart which shows.

  If a notification is received from the earthquake early warning terminal 1 at the time of emergency, the operation of promptly reporting without missing the contents of the report for each communication target device will be described.

  First, when the earthquake early warning terminal 1 receives earthquake information from the Japan Meteorological Agency, it outputs an earthquake information notification signal and report contents to the console 2a (E10A). In the console 2a that has received the earthquake information notification signal via the multicore line 1a, the external input IF unit 2a-2 transmits the notification signal to the control unit 2a-1 through the control line 2a-B. If the control unit 2a-1 determines that the content of the notification signal is earthquake information, the voice control unit is configured to open the gate to the voice line 2a-A for each target device through the control line 2a-B. Instruct 2a-3.

  Then, the control unit 2a-1 encodes the audio input from the audio control unit 2a-3 through the audio line 2a-A into the digital signal and records it on the recording / reproducing unit A 2a-4. -Instruct via B. Similarly, the recording / playback unit B 2a-5 and the recording / playback unit C 2a-6 are instructed to encode and record the input sound into a digital signal.

  The voice control unit 2a-3 that has received the opening instruction from the control unit 2a-1 opens the internal gate on the voice line 2a-A connected to devices such as the loudspeaker amplifier 2b and the digital radio 2c. As a result of this release, the earthquake information from the earthquake early warning terminal via the external input IF section 2a-2 is transferred to the loudspeaker amplifier 2b, the recording / playback section A2a-4, the recording / playback section B2a-5, and the recording / playback section C2a-. To audio line 2a-A to 6.

  The recording / playback unit A 2a-4 encodes the voice input from the voice control unit 2a-3 via the voice line 2a-A into a digital signal by the coding unit 2a-4-1, and the voice file 2a-4 -2 is recorded (E102). The recording / playback unit B 2a-5 encodes the audio input via the audio line 2a-A into a digital signal by the encoding unit 2a-5-1 and records it in the audio file 2a-5-2. (E103). Similarly, the recording / reproducing unit C 2a-6 encodes the audio input via the audio line 2a-A into a digital signal by the encoding unit 2a-6-1 and records it in the audio file 2a-6-2. (E104).

  Then, the control unit 2a-1 turns on the power to the loudspeaker amplifier 2b through the control line 2a-B (E110) and requests the digital wireless device 2c to make a call connection to the digital slave station 5 (E111). ) For the analog radio 2d, a call connection request to the analog slave station 7 is made (E112), and the control unit 2a-1 makes a connection request to the telephone response server 2e through the control line 2a-B. (E113). Control of the target device for transmitting the earthquake information, the loudspeaker amplifier 2b, the digital radio 2c, the analog radio 2d, and the telephone response server 2e is performed almost simultaneously by the control unit 2a-1.

  In the case of the loudspeaker amplifier 2b that completes the power-on control almost immediately, the voice input from the voice control unit 2a-3 through the voice line 2a-A is amplified, and the earthquake information is amplified from the rooftop loudspeaker 3 ( E150).

  When communication with the digital slave station 5 to be notified is established in the digital radio 2c that has started the call connection processing, the fact that the call connection is completed is transmitted to the control unit 2a-1 through the control line 2a-B. . Receiving this call connection completion, the control unit 2a-1 instructs the recording / reproducing unit A 2a-4 through the control line 2a-B to decode the digital signal recorded in the audio file 2a-4-2. Do. Receiving the instruction, the recording / playback unit A 2a-4 reads the recorded content from the audio file 2a-4-2, converts the read digital signal into an analog signal at the decoding unit 2a-4-3, and outputs it. It transmits to the digital radio 2c via the audio line 2a-A (E105). The voice thus decoded is transmitted to the digital slave station 5 through the digital broadcast radio line 4 from the digital radio 2c, and is output from the digital slave station 5 (E151).

  When communication with the analog slave station 7 to be notified is established in the analog wireless device 2d that has started the call connection processing, the fact that the call connection is completed is transmitted to the control unit 2a-1 through the control line 2a-B. . Upon receiving this call connection completion, the control unit 2a-1 instructs the recording / playback unit B 2a-5 through the control line 2a-B to decode the digital signal recorded in the audio file 2a-5-2. Do. Receiving the instruction, the recording / playback unit B 2a-5 reads the recorded content from the audio file 2a-5-2, converts the read digital signal into an analog signal at the decoding unit 2a-5-3, and outputs it. It transmits to the analog radio 2d via the audio line 2a-A (E106). The voice thus decoded is transmitted to the analog slave station 7 through the analog broadcast radio line 6 from the analog radio 2d, and is output from the digital slave station 7 (E152).

  The telephone response server 2e that has received the connection request from the control unit 2a-1 transmits a connection response to the control unit 2a-1 through the control line 2a-B. Upon receiving this connection response, the control unit 2a-1 instructs the recording / reproducing unit C 2a-6 through the control line 2a-B to decode the digital signal recorded in the audio file 2a-6-2. . Receiving the instruction, the recording / playback unit C 2a-6 reads the recorded content from the audio file 2a-6-2, converts the read digital signal into an analog signal at the decoding unit 2a-6-3, and outputs it. It transmits to the telephone response server 2e via the voice line 2a-A. As a result, recording / accumulation of the decoded voice to the telephone response server 2e is started (E153).

  Then, when the notification signal of the emergency earthquake warning terminal 1 is finished and the output of the report content is stopped (E10B), in the console 2a that recognizes the stop of the notification signal of the earthquake information via the multicore line 1a, The external input IF unit 2a-2 transmits that the notification signal has been stopped to the control unit 2a-1 through the control line 2a-B.

  If the control unit 2a-1 recognizes the stop of the notification signal, the control unit 2a-1 instructs the audio control unit 2a-3 to block the gate to the audio line 2a-A for each target device through the control line 2a-B. I do.

  Then, the control unit 2a-1 turns off the power of the loudspeaker amplifier 2b through the control line 2a-B (E130), and ends the loudness of the earthquake information from the rooftop loudspeaker 3 (E160).

  Note that the control unit 2a-1 instructs the recording / reproducing unit A 2a-4 via the control line 2a-B to stop the process of encoding and recording the input voice into a digital signal ( E122). However, at this time, the recording / playback unit A2a-4 converts the read digital signal into an analog signal by the decoding unit 2a-4-3 unless the recording content is completely read from the audio file 2a-4-2. The process of outputting to the digital wireless device 2c continues.

  Further, the control unit 2a-1 instructs the recording / reproducing unit B 2a-5 via the control line 2a-B to stop the process of encoding and recording the input voice into a digital signal ( E123). At this time, however, the recording / playback unit B 2a-5 converts the read digital signal into an analog signal by the decoding unit 2a-5-3 unless the reading of the recorded content from the audio file 2a-5-2 is completed. However, the process of outputting to the analog wireless device 2c continues.

  Further, the control unit 2a-1 instructs the recording / reproducing unit C 2a-6 via the control line 2a-B to stop the process of encoding and recording the input voice into a digital signal. (E124). At this time, however, the recording / reproducing unit C 2a-6 converts the read digital signal into an analog signal by the decoding unit 2a-6-3 unless reading of the recorded content from the audio file 2a-6-2 is completed. Then, the process of outputting to the telephone response server 2e continues.

  When the recording / playback unit A 2a-4 completes reading the recorded contents of the audio file 2a-4-2 (E125), the recording / playback unit A 2a-4 confirms that the digital signal decoding process is completed via the control line 2a-B. Transmit to the control unit 2a-1. Receiving the completion of the decoding process, the control unit 2a-1 makes a call termination request to the digital radio 2c via the control line 2a-B (E131). The digital radio 2c performs a call disconnection process based on this call termination request, and ends a series of emergency earthquake bulletin reports to the digital slave stations 5 (E161).

  When the recording / playback unit B 2a-5 completes reading the recorded contents of the audio file 2a-5-2 (E126), the recording / playback unit B 2a-5 confirms that the digital signal decoding process has been completed via the control line 2a-B. Transmit to the control unit 2a-1. Receiving the completion of the decoding process, the control unit 2a-1 makes an end call request to the analog wireless device 2d via the control line 2a-B (E132). The analog radio 2d performs a call disconnection process based on the call termination request, and ends a series of emergency earthquake warning notifications to the analog slave stations 7 (E162).

  When the recording / reproducing unit C 2a-6 completes reading of the recorded contents of the audio file 2a-6-2 (E127), the recording / reproducing unit C 2a-6 confirms that the decoding process of the digital signal is completed via the control line 2a-B. Transmit to the control unit 2a-1. Receiving the completion of the decryption process, the control unit 2a-1 issues a disconnection request to the telephone response server 2e via the control line 2a-B (E133). By this disconnection processing, the voice response server 2e completes the voice accumulation of the contents of the report (E163), and the local residents who wish to confirm the contents of the report after the end of the earthquake early warning report the telephone network 9 from each residential home phone 10 and The inquiry via the subscriber line 8 can be dealt with by reproducing the voice stored in the telephone response server 2e.

  In this way, if there are multiple notification target devices in the disaster prevention radio, such as call connection and the time from the start of notification to the time when notification is possible, if the earthquake information from the emergency earthquake warning terminal is received, the notification It is possible to realize an operation console that does not have a missing content voice and can promptly report.

  A console according to Embodiment 2 of the present invention will be described. The console according to the present embodiment has the same configuration as the console shown in FIG. 1 according to the first embodiment of the present invention described above, and the description thereof is omitted here.

  FIG. 3 is a timing chart showing an operation for carrying out a report including real-time contents such as a countdown from the earthquake early warning terminal according to the second embodiment of the present invention.

  Recognize from the information notified from the earthquake early warning terminal 1 that the report includes a real-time content such as a countdown, and rewrite the content to correct the difference between the countdown and the real time due to the activation of the target device. The operation will be described.

  In order to simplify the following description, the operations of the recording / playback unit B 2a-5, the analog radio 2d, and the analog slave station 7 will be mainly described.

  First, when the earthquake early warning terminal 1 receives earthquake information from the Japan Meteorological Agency, it outputs an earthquake information notification signal and a report content to the console 2a (E20A). In this case, the content of the report is accompanied by countdown information, and an identifier which is a highly real-time report content is present in the notification signal.

  In the console 2a that has received the notification signal via the multicore line 1a, the external input IF unit 2a-2 transmits the notification signal to the control unit 2a-1 through the control line 2a-B.

  If the control unit 2a-1 determines that the content of the notification signal, particularly the identifier is a highly real-time notification content, the control unit 2a-B opens the gate to the voice line 2a-A for each target device through the control line 2a-B. The voice control unit 2a-3 is instructed to perform

  Then, the control unit 2a-1 encodes the voice input from the voice control unit 2a-3 through the voice line 2a-A into the digital signal and records it on the recording / playback unit B 2a-5. -Instruct via B.

  The voice control unit 2a-3 that has received the opening instruction from the control unit 2a-1 opens the internal gate on the voice line 2a-A connected to devices such as the loudspeaker amplifier 2b and the digital radio 2c. With this release, it is output to the audio line 2a-A to the recording / reproducing unit B 2a-5. The recording / playback unit B 2a-5 encodes the audio input via the audio line 2a-A into a digital signal by the encoding unit 2a-5-1 and records it in the audio file 2a-5-2 ( E203). Then, the control unit 2a-1 makes a call connection request to the analog slave station 7 to the analog wireless device 2d through the control line 2a-B (E212).

  When communication with the analog slave station 7 to be notified is established in the analog wireless device 2d that has started the call connection processing, the fact that the call connection is completed is transmitted to the control unit 2a-1 through the control line 2a-B. . Upon receiving this call connection completion, the control unit 2a-1 instructs the recording / playback unit B 2a-5 through the control line 2a-B to decode the digital signal recorded in the audio file 2a-5-2. Do. Further, the control unit 2a-1 stores the time (T) from the start to the completion of the call connection of the analog wireless device.

  Receiving the instruction, the recording / playback unit B 2a-5 reads the recorded content from the audio file 2a-5-2, converts the read digital signal into an analog signal at the decoding unit 2a-5-3, and outputs it. It transmits to the analog radio 2d via the audio line 2a-A (E206). The voice thus decoded is transmitted to the analog slave station 7 through the analog broadcast radio line 6 from the analog radio 2d, and is output from the analog slave station 7 (E252).

  Now, since the content of the report is a highly real-time content including countdown information, the recording / playback unit B 2a-5 is instructed to decode, and the control unit 2a-1 processes the content of the report (FIG. 3). "★ About processing"). In general, in the case of such a report, the control part 2a-1 causes the recording / reproducing part B 2a-5 to perform decoding as it is for a predetermined period since it is important information explaining the seismic intensity at first. When this predetermined period has elapsed, the control unit 2a-1 deletes the contents of the audio file 2a-5-2 for the predetermined period stored previously. After completion of deletion, the content of the remaining audio file 2a-5-2 is decrypted to the end.

The recording / reproducing unit B 2a-5, when reading of the recorded contents of the audio file 2a-5-2 is completed (E226), indicates that the digital signal decoding process is completed via the control line 2a-B. Transmit to the control unit 2a-1. Receiving the completion of the decoding process, the control unit 2a-1 makes an end call request to the analog wireless device 2d via the control line 2a-B (E232). The analog radio 2d performs a call disconnection process based on the call termination request, and ends a series of emergency earthquake bulletin reports to the analog slave stations 7 (E262).
In this way, from the information notified from the earthquake early warning terminal 1 at the time of emergency, it is recognized that the report includes a real-time content such as a countdown, and the difference between the countdown and the real time associated with the activation of the device to be reported is detected.

Also explains the operation to amplify the optimal information for the region. In order to simplify the following description, the operations of the recording / playback unit B 2a-5, the analog radio 2d, and the analog slave station 7 will be mainly described. Prior to operation, information suitable for the region is registered as a digital signal in the audio file 2a-5-2 of the recording / playback unit B 2a-5 of the console 2a.

  First, when the earthquake early warning terminal 1 receives earthquake information from the Japan Meteorological Agency, it outputs an earthquake information notification signal and report contents to the console 2a. In this case, an identifier that can be known about the content of the report is present in the notification signal.

  In the console 2a that has received the notification signal via the multicore line 1a, the external input IF unit 2a-2 transmits the notification signal to the control unit 2a-1 through the control line 2a-B. When the control unit 2a-1 recognizes the content of the notification signal by the identifier and determines that the information needs to be changed to the information most suitable for the region, the control unit 2a-1 transmits an analog signal to the analog radio 2d through the control line 2a-B. A call connection request to the station 7 is made.

  When communication with the analog slave station 7 to be notified is established in the analog wireless device 2d that has started the call connection processing, the fact that the call connection is completed is transmitted to the control unit 2a-1 through the control line 2a-B. . Upon receiving this call connection completion, the control unit 2a-1 controls the recording / playback unit B 2a-5 so as to decode the digital signal previously recorded in the audio file 2a-5-2 as the optimum information for the region.
