When the playback switch 38 for playing back the recorded notification broadcast is pressed, the light is turned off. Therefore, since the general notification lamp 34 or the emergency notification lamp 35 keeps blinking unless the received recording of the notification broadcast is confirmed by the operation of the playback switch 38, even when the terminal user is in the absence of the notification broadcast, You can easily know that there was an announcement broadcast.

  When the reproduction switch 38 for reproducing the recorded announcement broadcast is pressed, the receiver control unit 17 as reproduction means selects the announcement broadcasts stored in the audio memory 31 in descending order of importance and reproduces them from the speaker 25. To do. That is, the terminal user can listen to important emergency notification broadcasts and the like, which is convenient when it is not possible to take a long time to confirm unconfirmed notification broadcasts.

  Next, group setting for performing group broadcasting will be described. The group address is set by transmitting group setting data from the notification broadcast transmission unit 12 to each notification broadcast receiver 16. The group setting data has a format similar to that of the notification broadcast, and the type of data can be set to either the notification broadcast or the group setting data by the control information. The notification broadcast receiver 16 performs the above-described notification broadcast processing when the received data is notification broadcast, and performs group setting processing when the received data is group setting data.

  The group setting data is configured by associating the individual address of the notification broadcast receiver 16 with the address of the group to which the individual address belongs. Data in which individual addresses and group addresses are associated with each other is created in advance using another computer or the like, and is input to the center device 3 by a recording medium storing the data. However, direct input may be performed using the operation unit 11 and the display 9 of the center device 3.

  When the individual address and the group address are input to the center device 3, the control unit 4 stores them in the memory 40 in association with each other. When performing group setting processing for all notification broadcast receivers 16 as the initial setting of the entire system, the control unit 4 acquires all individual addresses and group addresses from the memory 40, and generates group setting data based on this. To do.

  When a new broadcast receiver 16 is added, when only a specific broadcast receiver is unable to receive data, and when there is a possibility that the data has not arrived, a specific broadcast receiver or a specific broadcast receiver When it is desired to set a group only, the selection unit 4a of the control unit 4 generates group setting data after selecting an arbitrary range from the individual address and group address stored in the memory 40. The selection unit 4a displays the individual address and the group address in correspondence with each other on the display 9, and acquires the individual address and the group address selected by the operation unit 11. FIG. 3 shows a display example on the display 9.

  As shown in FIG. 3, the display 9 displays a group number, a group name, and individual addresses belonging to the group. A group can be selected on the screen by the operation unit 11. The selected group is displayed as if the check box on the left side of the screen is checked. However, any display method may be used. For example, the selected group may be displayed in reverse video.

  In FIG. 3, the range can be specified for each group, but the range may be specified for each notification broadcast receiver 16. In this case, the individual address and the corresponding group address can be displayed as a table on the display 9 and an arbitrary range can be selected by the operation unit 11.

  The individual address and group address acquired by the selection unit 4 a are generated as group setting data by the control unit 4 and transmitted from the notification broadcast transmission unit 12 to the notification broadcast receiver 16. As described above, the group setting data generated by the control unit 4 is within the range selected by the selection unit 4a, so that data to be transmitted can be reduced. Therefore, setting by one transmission can be performed in a short time.

  When a plurality of ranges are selected by the selection unit 4a, the control unit 4 generates group setting data for each, and sequentially transmits the group setting data from the notification broadcast transmission unit 12. Here, the transmission of the group setting data can be efficiently performed by utilizing the idle time of the announcement broadcast. For this purpose, the control unit 4 causes the notification broadcast transmission unit 12 to transmit the group setting data after the notification broadcast is finished and before the next notification broadcast is started. The group setting data is transmitted by using the free time of the notification broadcast, not only when a plurality of ranges are selected by the selection means 4a, but also when a single range is selected. Can do.

  Furthermore, the transmission date and time of the group setting data can be set in advance for the control unit 4. The transmission date and time is set using the display 9 and the operation unit 11. When the control unit 4 detects the set date and time from the input from the calendar circuit 37, it transmits the group setting data to the notification broadcast transmission unit 12. . As a result, the time when the group setting data is transmitted by the administrator can be set in advance to a time zone during which no announcement broadcast is performed.

  When the notification broadcast or the group setting data is transmitted, the control unit 4 displays various information on the display 9. Here, when transmitting the group setting data, the control unit 4 counts the number of individual addresses included in the group setting data transmitted to the notification broadcast transmission unit 12 and displays the counted number on the display 9. As a result, the administrator can easily determine whether the number of the notification broadcast receivers 16 that are to set the group address matches the number of individual addresses of the notification broadcast receivers 16 that are actually transmitted as group setting data. Can grasp.

  As mentioned above, although embodiment of this invention was described, application of this invention is not restricted to these embodiment, It can apply variously within the range of the technical idea.
