[Disaster prevention broadcasting through contact calls]
Hereinafter, in addition to FIGS. 1 and 2, the disaster prevention broadcast processing by the communication call of the present embodiment will be described with reference to the flowchart of FIG. 3.

  First, in normal broadcast processing, the broadcast operation device 10 is activated in response to an operation of the operation console 11 from the master station system 1, and an audio signal (broadcast content) input from a microphone (not shown) is transmitted to the wireless device 13. To do. The wireless device 13 transmits an audio signal (radio wave) to the slave station 30 in the district designated by the broadcast operation device 10 via the antenna 14. Specifically, the wireless device 13 transmits an audio signal (radio wave) including a code indicating the slave station 30 in the designated area.

  In the slave station 30 in the designated area, the wireless device 31 extracts an audio signal including the designated code from the radio wave received by the antenna 32 and sends it to the loudspeaker 33. Thereby, in the designated district, the broadcast content (administrative communication, notification for disaster prevention, etc.) can be broadcasted loudspeaker from the loudspeaker 33.

  Next, the broadcast processing of this embodiment will be described. As described above, the present embodiment is a broadcast process using a communication call function by a PB telephone 34 from a slave station 30A installed in an evacuation center (a school, a public hall, etc.), for example.

  In the slave station 30A, the PB telephone 34 is operated to connect to the telephone 16 of the master station system 1 and set to the communication call state. In this case, a broadcast designation code and a broadcast district code are input on the PB of the PB telephone 34 (step S1). The broadcast designation code is a code that designates a broadcast process (here, disaster prevention broadcast) using a contact call. The broadcast district code is a code that designates the slave station 30 (including the slave station 30A) in the district where the broadcast is performed.

  Next, the PB telephone 34 transmits the broadcast contents (contact for disaster prevention, etc.) (step S2). The radio device 31 of the slave station 30A transmits the broadcast designation code, the broadcast district code, and the broadcast content (such as disaster prevention communication) input from the PB telephone 34 by radio waves from the antenna 32 (step S3).

  On the other hand, in the master station system 1, when receiving the radio wave from the slave station 30A via the antenna 14, the wireless device 13 sends it to the broadcast control device 20 after predetermined signal processing (step S10). In the broadcast control device 20, the data processing unit 22 analyzes the code information (PB tone signal) transmitted from the PB telephone 34 (step S11). When the broadcast designation code and the broadcast district code are extracted by the analysis processing of the data processing unit 22, the broadcast control device 20 proceeds to the broadcast processing by the communication call (YES in step S12).

  Here, the broadcast control apparatus 20 shifts to a call process when the broadcast designation code is not extracted or the call designation code is extracted by the analysis processing of the data processing unit 22 (NO in step S12). In this case, the broadcast control device 20 transfers an audio signal corresponding to the transmission from the PB telephone 34 from the wireless device 13 to the PBX 17. As a result, the telephone set 16 of the master station system 1 and the PB telephone set 34 of the slave station 30A are connected via the PBX 17 to enable a call between the master station and the slave station, and a normal communication call is performed.

  The broadcast control device 20 records (records) an audio signal corresponding to the broadcast content (such as disaster prevention communication) transmitted from the PB telephone 34 in the recording unit 21 in accordance with the transition to the broadcast processing (step S13). . Furthermore, the broadcast control device 20 sends the broadcast district code extracted by the analysis processing of the data processing unit 22 to the broadcast operation device 10 and sets it (step S14).

  The broadcast operating device 10 is activated in accordance with the setting of the broadcast district code from the broadcast control device 20, and the audio signal (audio information indicating disaster prevention communication) recorded (recorded) in the recording unit 21 is transmitted from the radio device 13. Distribution is performed (step S15). Here, the broadcast control apparatus 20 may be configured to send the audio signal recorded in the recording unit 21 together with the broadcast district code to the broadcast operation apparatus 10. In this case, the broadcast operation device 10 sends an audio signal to the wireless device 13.

  The wireless device 13 transmits an audio signal (radio wave) including a code (designated code of the slave station 30) corresponding to the set broadcasting district code via the antenna 14. As a result, in the slave station 30 in the designated area, the wireless device 31 extracts an audio signal including the designated code from the radio wave received by the antenna 32 and sends it to the loudspeaker 33. Thereby, in the designated area, the broadcast content (such as disaster prevention communication) can be broadcasted loudly from the loudspeaker 33.

  As described above, according to the present embodiment, in addition to broadcast processing for performing normal administrative communication and disaster prevention notification by the broadcast operation device 10 of the master station system 1, for example, in an evacuation center (school, public hall, etc.) Broadcast processing using the communication call function by the PB telephone 34 can be performed from the installed slave station 30A. That is, for example, an evacuee or administrative staff in an evacuation center uses the PB telephone 34 installed in the slave station 30A to transmit the broadcast contents (such as disaster prevention communication) to the master station system 1 by sending a message. . The broadcast control device 20 of the master station system 1 automatically records an audio signal indicating the content of the broadcast, and starts a broadcast process using a communication call.

  In the system according to the present embodiment, for example, an evacuee or administrative staff in an evacuation center uses the PB telephone 34 installed in the slave station 30A, and the slave station 30 in the designated district. A loudspeaker 33 can be used to broadcast disaster prevention communications. Therefore, if the system of the present embodiment is applied to a disaster prevention system, an effective disaster prevention broadcast function based on a communication call can be realized in addition to the normal broadcast function from the master station. In addition, with the configuration of the present embodiment, the PB telephone 34 for contact calling is also used for broadcast processing by contact calling, so there is an effect that can be realized at low cost.
