Abstract

PROBLEM TO BE SOLVED: To eliminate trouble of a sender by providing a voice information output means and a teletext information display means and providing a notice broadcast when address data from a center equipment are coincident with address data set in itself. SOLUTION: Upon receipt of broadcast start data from a center equipment 3, notice broadcast receiver 31 compares address information or block information included in the data with its own setting address or a block number allocated to itself. When the comparison result indicates coincidence, whether a broadcast is an emergent broadcast or a general broadcast is identified. In the case of the emergent broadcast, an emergency lamp 35 is lighted and an LCD display device 48 is flashed so that the reception of a notice broadcast is understood even by a person having difficulty in hearing. That is, in the case of a black/ white liquid crystal display device, inversion of black/white level makes a notice. Then a sound volume adjustment section 28 set to the emergency broadcast mode is adjusted to increase a sound volume of a notice broadcast from a speaker 25.

On the other hand, the audio signal of the demodulated signal is sent to the audio amplifier 24 and the speaker 25 as the audio information output means. That is, the audio signal is amplified by the audio amplifier 24 and output as sound from the speaker 25. In addition, in front of the audio amplifier 24, a volume adjusting unit 28 for adjusting the volume from the speaker 25.
Is provided.

Further, the announcement broadcast receiver 31 is provided with a RAM 32 which is a text information storage means for storing text information and a classification data storage means for storing classification data added to the announcement broadcast. CPU 17 is the center device 3
When receiving the broadcast start data from, the storage operation is instructed to the LCD driver 47. Then, a storage process for storing the character information output from the FM receiving unit 22 and demodulated by the character information demodulating unit in the RAM 32 is performed. This storage processing is performed until the storage end output of the CPU 17 is given by the reception of the broadcast end data transmitted from the center device 3 at the end of the broadcast. The number of times of display of the character information transmitted from the center device 3 is stored in the number-of-times setting unit 39 which is connected to the CPU 17 and serves as a number-of-displays storage unit.

Further, the external input / output device 21 is connected with a notification lamp for notifying the storage state of the notification broadcast. In this system, the means for transmitting broadcasts to terminal users is

Therefore, the notification lamp is also provided with an emergency lamp 35 for emergency notification broadcasting and a notification lamp 34 for general notification broadcasting. Further, the external input / output device 21 is provided with a confirmation switch 36 as a switch means for confirming that the terminal user has heard the announcement broadcast. Furthermore, RAM
A display switch 38, which serves as a switch for causing the LCD driver 47 to display and output the character information of the announcement broadcast stored in 32, is connected.

Notification lamp 34 or emergency lamp 35
Is driven to a lighting state while the announcement broadcast is received and stored in the memory, and is switched to a blinking state when the reception storage of the announcement broadcast is completed. In addition, confirmation switch 3 after the end of broadcasting
6 or when the display switch 38 for displaying the stored notification information is pressed, it is turned off. Therefore, the notification lamp 34 or the emergency lamp 35 keeps blinking unless the reception of the notification broadcast is confirmed by the operation of the confirmation switch 36 or the display switch 38. Therefore, even if the notification broadcast is made while the terminal user is away from home, You can easily know that there was a notification broadcast.

Next, the announcement broadcasting process in the embodiment of FIG. 1 will be described with reference to FIG. First, the broadcast processing in the center device 3 will be described. The transmission process is performed according to the flowchart of FIG. First, the CPU 4 monitors the decision block 40 as to whether or not the announcement broadcasting mode has been set by operating the keyboard 11 or the like. If the announcement broadcast mode is selected by operating the keyboard 11, block 4 is displayed.
Go to 1. In block 41, the type of notification broadcast is a general broadcast or an emergency broadcast is set according to the keyboard input. In the case of general broadcasting, further general announcement broadcasting or B
The type of GM broadcast is set. Next, in block 42, the number of times of displaying the character information of the announcement broadcast on the LCD display unit 48 of the announcement broadcast receiver 31 is set.

In block 43, the address of the terminal device 16 targeted for the announcement broadcast is designated. The designation of the terminal address to be broadcast is performed by setting and inputting the terminal code using the keyboard 11. Alternatively,
The terminals to be notified may be divided into blocks in units of administrative areas such as service areas or condominiums, and the address information of the broadcasting terminals may be stored in the ROM 6 or the like in blocks. In this case, by designating the block number with the keyboard 11, the terminal address to be broadcast is designated. Alternatively, conversely, only the block number may be designated and transmitted on the side of the center device 3, and the terminal device 16 side may be set to judge whether or not its own terminal is set in the transmitted block. it can. Furthermore, when performing an emergency notification broadcast such as in the case of a fire, when the input setting 41 by the keyboard 11 is performed, all the subscribed terminals are automatically addressed as broadcast targets under the program control by the CPU 4. May be.

When the addressing of the broadcast terminal is completed in block 43, the CPU 4 sends out the broadcast start data (block 44) before transmitting the announcement broadcast. As shown in FIG. 3, this broadcast start data includes the address information specified in block 43 and the general / general information set in block 41.
Urgent broadcast type, display count set in block 42,
Further, it has a frame structure composed of a start signal for starting broadcasting. When the transmission of the broadcast start data in block 44 is completed, the process proceeds to the next block 45, and the character and voice announcement broadcast is transmitted. And the keyboard 11,
A modulation signal of a voice signal or a character signal by the microphone 13 or the BGM source 33 is transmitted to the terminal side via the transmission line 1. Further, at this time, the transmission start time or the broadcast end time of the announcement broadcast is read from the calendar circuit 37 and transmitted together with the broadcast data. The calendar circuit 37 may be held by the terminal device 16 side.

When the character and voice announcement broadcast of block 45 is completed, the CPU 4 is notified of the end of the voice announcement broadcast by operating the keyboard 11, for example, and the broadcast end data shown in block 46 is transmitted. This completes the transmission processing on the side of the center device 3. By the center broadcasting process shown in FIG. 2, the signal transmitted to the terminal side is as shown in FIG. 3 when the signal transmission to the single terminal device 16 is taken as an example. That is, address, type of announcement broadcast, number of times of display,
Broadcast start data including a start signal is transmitted, a notification signal that is the content of the announcement broadcast is transmitted, and after the broadcast ends, broadcast end data including an address and a stop signal is transmitted. Further, the broadcast end data may be only the stop signal.

Next, with reference to FIG. 4, the processing on the receiving side of the announcement broadcast will be described. FIG. 4 is a flowchart showing a reception process of the announcement broadcast receiver 31 provided in the terminal device 16 in the embodiment of FIG. The notification broadcast receiver 31 is always in a state of receiving data from the center device 3 side, as shown in block 61. In this state,
When the broadcast start data is received from the center device 3, the determination block 62 compares the address information or the block information included in the broadcast start data with the set address of itself or the block number assigned to itself, and if a match is obtained. Proceed to next block 63. In the determination block 63, the type of notification broadcast, that is, whether it is an emergency broadcast or a general broadcast, is identified, and if it is an emergency broadcast, the process proceeds to block 64. Block 64 when it is determined that the broadcast is an emergency broadcast
Then, the emergency lamp 35 is turned on, and the LCD display unit 48 is flushed first so that even a hearing-impaired person can know that the notification broadcast has been received. In other words, if the liquid crystal is a black and white liquid crystal, the black and white liquid crystal is inverted to be noticed (block 65). Then, the emergency broadcast mode is set (block 66), and the volume adjusting unit 28 is adjusted in block 67 so that the volume of the announcement broadcast from the speaker 25 is increased.

On the other hand, if it is determined in the decision block 63 that the broadcast is the general broadcast, the decision lamp 68 turns on the notification lamp 34, and the decision block 69 identifies whether the broadcast is the general broadcast or the BGM broadcast. . Here, in the case of the general announcement broadcast, the process proceeds to block 70 and the general announcement mode is set. On the other hand, if it is determined in block 69 that it is BGM broadcasting, the process proceeds to block 71, the music broadcasting mode is set, and the BGM transmitted from the center apparatus 3 is sent.
Keep flowing. When the stop signal of the broadcast end data transmitted from the center device 3 is identified in block 72, the music broadcast mode is ended (block 73), the notification lamp 34 is turned off (block 74), and the center device 3 side at all times is operated. The state returns to the state in which the data from can be received (block 61).

If the broadcast mode is the emergency broadcast mode or the general announcement broadcast mode, it is determined in block 75 whether or not the previous announcement broadcast or the like has already been stored in the RAM 32, and if so, it is stored. Is determined to be updated. That is, it is determined which of the announcement broadcast type data newly sent from the center device 3 and the type data already stored in the RAM 32 is the type data having a higher priority. Naturally, this priority is set so that the emergency broadcast is higher than the general announcement broadcast. For example, when the urgent notice broadcast is already stored in the RAM 32, the RAM 32 is not stored and updated even if the general notice broadcast is subsequently sent, and only the voice notice is issued. On the contrary, when the general notification broadcast is stored and then the emergency notification broadcast is further received, the storage of the RAM 32 is updated by giving priority to the emergency notification broadcast. In addition, when the general announcement broadcast is already recorded or when the general announcement broadcast is transmitted, or when the emergency notification broadcast is already recorded or when the emergency notification broadcast is transmitted, the same priority is given. When the broadcast of the same time is transmitted, the record of the RAM 32 is updated. However, RAM3 is used separately for emergency notification and general notification.
When equipped with 2, RAM3 corresponding to the announcement broadcast mode
2 may be updated every time. If it is determined in this block 75 that the update should not be performed, a block 85 described later is executed.
Proceed to block 76 if it is determined that the update should be made.
Proceed to.

In block 76, the type of character information to be recorded is stored. The type of the character information stored here serves as reference data when determining whether the storage may be updated in the block 75. Then, in block 77, the display count in the broadcast start data sent from the center device 3 is stored in the count setting unit 39. Next, when a start signal for starting the announcement broadcast is received in block 78, in block 79, the letter signal of the announcement broadcast received by the FM receiver 22 is converted into text information by the letter information demodulator 50, and LC
Write to the RAM 32 in real time via the D driver 47. During this period, the output of the FM receiving unit 22 is given to the LCD driver 47 and the LCD display unit 48.
It is displayed on the CD display unit 48. Here, when the LCD display unit 48 can display only a small number of characters at a time, it is not possible to display all the character information at a time. A method is used in which information is divided and switched to be displayed.

The output of the FM receiving unit 22 is also given to the speaker 25 via the volume adjusting unit 28 and the audio amplifier 24, and broadcast output is provided. In the case of the emergency broadcast mode, the speaker 25 output is set to a high volume by the volume adjusting unit 28, and the terminal user is informed of the announcement broadcast content with a loud sound. When the transmission of a series of broadcasts is completed, the stop signal is transmitted from the center device 3 as broadcast end data. When the CPU 17 receives this stop signal in block 80, it instructs the LCD driver 47 to stop the storage operation (block 81).

Next, in block 82, the character information written in the RAM 32 is displayed from the center device 3 for the number of times of display set in advance in block 77. That is, when the LCD display unit 48 can display a large number of characters at a time, the terminal user can be surely read the character information by keeping the character information displayed on the LCD display unit 48. However, the LCD display unit 48, which has a small number of characters that can be displayed at one time, displays the sent character information by a method of displaying it in a flowing manner from the beginning or a method of dividing and displaying the information. Therefore, since there is a possibility that the terminal user may miss the character information, repeated display is performed. This display frequency is naturally set to a large number in the case of important information such as fire information and earthquake information.

When the stored broadcast contents are repeated by the set number of times of display and the display is completed (blocks 83 and 84), the process proceeds to block 85, and the emergency lamp 35 or the notification lamp 34, which has been in the lighting state until then, is changed to a blinking state. .
The blinking state of these notification lamps indicates that the content broadcast by the notification broadcast is stored. If the terminal subscriber is listening to the announcement broadcast, the confirmation switch 36 is operated. The ON operation of the confirmation switch 36 is determined in block 86, and in response to the output of the confirmation switch 36, the CPU 17 turns off the emergency lamp 35 or the notification lamp 34 in block 87, and the block 88.
Then, the type data stored in the block 76 is erased. This is because, since the resident has already confirmed the announcement broadcast, the stored data is unconditionally updated in block 75 when the next announcement broadcast is made. Then, in the next block 89, the broadcast mode is ended. Then, a series of reception processing is ended.

On the other hand, the confirmation switch 36 may be operated when the terminal subscriber is out of the announcement broadcast or does not notice the broadcast because the speaker 25 has been turned down in the general announcement mode. Absent. In this case,
Depending on the type of notification broadcast, an emergency lamp 35 or a notification lamp 34 indicating that the notification broadcast is stored
Keeps blinking. Therefore, the terminal subscriber who cannot hear the announcement broadcast can know that the announcement broadcast is stored by blinking the emergency lamp 35 or the announcement lamp 34. Then, by operating the display switch 38, the stored data stored in the RAM 32 can be displayed on the LCD display unit 48.

That is, when the confirmation switch 36 is off, the process proceeds from the determination block 86 to 90, and the operation of the display switch 38 is checked. Here, the display switch 38
When is pressed, the process proceeds to block 91, and the memory display is performed. This stored display may be performed the number of times of display set in block 77, or may be displayed only once. Note that, when the display switch 38 is operated to display the character information in a flowing manner, if the display switch 38 is operated again, the display may be reset and the character information may be displayed from the beginning. In this case, even if you can't keep your eye on the flowing letters, you can see them again right away from the beginning. Further, a pause switch may be provided so that the flowing character information can be stopped and read. Alternatively, the display speed of characters may be changed by operating a switch.

After the character information is displayed by operating the display switch 38 in this way, the time at which the announcement broadcast was read out from the calendar circuit 37 of the center device 3 and sent out is displayed on the LCD display section 48. To be done. Then, the broadcast operation is completed through the blocks 87, 88 and 89 described above,
After that, the state again returns to the state of always receiving data from the center device 3 side (block 61). However, since the character information itself stored in the RAM 32 is not updated until the next notification broadcast is made even after the broadcast operation ends, the display switch 3
By operating 8, information can be displayed many times.

Before the display switch 38 is operated by the occupant in block 90, it is always in a waiting state for receiving new announcement broadcast data (block 9).
2) If the reception of new announcement broadcast data is recognized in this block 92, the process proceeds to block 93, and the address information or block information included in the new broadcast start data is assigned to the self-set address or self. The block number is compared, and if a match is obtained, the process proceeds to block 63 again.

Next, a second embodiment of the announcement broadcasting system according to the present invention will be described. The announcement broadcasting system includes a sending confirmation means for sending confirmation data to the center apparatus 3 side in response to a confirmation operation indicating that the announcement broadcasting has been received on the terminal apparatus 16 side. Therefore, both the terminal device 16 and the center device 3 have a transmission / reception function.
Specifically, the terminal device 16 shown in FIG.
2 and an FM transmitter, and the center device 3 may also include the FM transmitter 22 and the FM receiver 22. In addition,
In this case, the transmission signal amplifier 29 on the transmission line 1 may be a bidirectional amplifier. The specific procedure for confirming transmission is performed as follows. That is, since the confirmation switch 36 is provided on the side of the terminal device 16, the terminal subscriber who sees the announcement broadcast operates the confirmation switch 36,
The PU 17 sends confirmation data including a terminal address and confirmation information to the center device 3. If the terminal user is absent during the announcement broadcast, the confirmation data may be sent when the display switch 38 is operated.

In the second embodiment, an operation for receiving confirmation data from the terminal device 16 side is performed after the broadcast end data transmission (block 46) in the flowchart of FIG. 2 showing the processing on the center device 3 side. Is added. That is,
On the side of the center device 3, the confirmation data is received and the confirmation data is aggregated. Specifically, after a lapse of a certain time after the end of broadcasting, it is checked whether or not the confirmation data of all terminals targeted for broadcasting designated in block 43 have been obtained. If the confirmation data of all terminals have been obtained, a series of broadcast processing is ended. On the other hand, when the confirmation data of all the terminals cannot be obtained, the number of unconfirmed terminals, addresses, assigned blocks, and the like are displayed on the display 9 or printed on the printer 10. By this operation, it is possible to know how many terminals the announcement broadcast has reached. In this manner, the fact that the center device 3 can know to what extent the notification broadcast has been transmitted to the center device 3 can be useful in taking an administrative action or the like to the broadcast target area after the emergency broadcast, especially in an emergency.

In the first and second embodiments described above, the case where all of the emergency broadcast mode, the general announcement mode and the BGM mode are provided has been described. The announcement broadcasting system of the present invention does not necessarily have to have all of these three modes. That is, any one or two of these three modes can be easily changed and implemented.

The embodiment described above is C
The system configuration using the coaxial cable line of the ATV system as the transmission line 1 has been taken as an example. However, the present invention is not limited to this, and is similarly applicable to the case where a signal line dedicated to announcement broadcasting is used. Alternatively, not only repetitive broadcasting of character information but also repetitive broadcasting of voice information may be performed. This is because the notification broadcast receiver 31 is provided with a recording unit similar to the RAM 32,
It may be used as a reproduction number storage means for storing the number of times of reproduction of the voice information and a voice information storage means for storing the voice information. Then, on the side of the center, when transmitting the announcement broadcast (block 42 in FIG. 2), not only the number of times the text information is displayed but also the number of times the voice information is reproduced may be set and transmitted in addition to the announcement broadcast. Then, through the same processing as the repeated display of the character information as described above, the speaker 2
5 may be repeatedly output. Also in this case, processing such as prioritization of information update may be performed similarly to the display of character information. As a result, even more reliable notification broadcasting can be performed for terminal users other than those who are hard of hearing.

Various modifications can be made to the number of times character information is displayed and the number of times voice information is reproduced on the terminal side.
That is, when setting the number of times of display and the number of times of reproduction for the emergency notification broadcast and the general notification on the side of the center device 3, by separately setting in advance, the number of times of display and the number of times of reproduction on the side of the terminal device 16 can be set. Can be controlled. In this case, the number of times of display and the number of times of reproduction may be set according to the type of notification broadcast in block 42 of the flowchart of the transmission process in FIG. Alternatively, on the notification broadcast receiver 31 side, the frequency setting unit 3
9, the number of times of display and the number of times of reproduction for each type of notification broadcast transmitted from the center device 3 side may be stored in advance in a memory.

Further, in the above invention, when the emergency broadcast mode is set, the volume adjusting unit 28 is set to the maximum volume. However, when the terminal user who is out of the office later displays and stores and listens to the announcement broadcast, it does not necessarily have to be set to the maximum volume. Therefore, display switch 3
The CPU 17 may be set so that the sound volume from the speaker 25 is automatically set to the normal sound volume in a state in which 8 is operated. Regarding the storage processing in the announcement broadcast receiver 31 on the side of the terminal device 16 in the present invention, it is sufficient that at least the start signal for the start of broadcasting and the stop signal for the end of broadcasting from the side of the center device 3 can be transmitted. No dedicated data transmission device is required on the device 16 side. The processing procedure in this case can be specifically realized as follows.
That is, the FM transmitter 12 itself sends out a broadcast start signal of a predetermined frequency to notify the start of broadcast before the start of broadcast. Then, after the end of the broadcast, a broadcast end signal of a predetermined frequency may be transmitted, the FM receiver 22 of the terminal device 16 may identify the signal, and the storage control of the LCD driver 47 may be performed. Of course, the CP between the center device 3 and the terminal device 16
Data transmission may be performed under communication control by U. In this case, the notification broadcast receiver 31 on the side of the center device 3 and the terminal device 16 may be provided with a dedicated data transmission device for transmitting and receiving the broadcast start and broadcast end data.

Further, in the above embodiment, the case where the address of the terminal to be broadcast or the block number to which the terminal belongs is designated by the center device 3 side by data transmission has been described. However, the present invention is not limited to this, and can be similarly applied to a case where notification broadcasting is simultaneously performed for all terminals without addressing the terminals to be broadcast. The method of designating the terminals to which the character information and the voice information are transmitted may be designated only to the terminals where the hearing-impaired person is at home, or the character information may be transmitted to all the terminals to which notification broadcasting is desired.

[0038]

As described above, according to the present invention as set forth in claim 1, the center device is a terminal device which wants to receive the announcement broadcast data including the announcement broadcast including arbitrary voice information and character information. Of the voice data from the center device, and an address setting unit for setting its own unique address, and a voice for outputting voice information from the center device. An information output unit and a character information display unit for displaying character information are provided, and when the address data added to the notification broadcast from the center device matches the address data set by itself, the notification broadcast is performed. As a result, not only the conventional announcement broadcast by voice output but also the announcement broadcast by character display can be performed, and particularly effective announcement broadcast can be performed for the hearing impaired person. Kill.

Moreover, according to the present invention as set forth in claim 2,
The terminal device is provided with a display count storage unit for storing the display count of the character information and a character information storage unit for storing the character information. When the amount of character information that can be displayed on the terminal is greater than that of the character information, the character information is repeatedly displayed the number of times stored by the display count storage means, so that the terminal can display the character information in a divided manner. The user can repeatedly view the character information, and the notification broadcast can be more reliably transmitted to the terminal user.

Further, according to the present invention as defined in claim 3, the terminal device is provided with a type data storage means for storing the type data added to the announcement broadcast, and the character information storage means is newly sent. Even if the terminal user is absent, the emergency broadcast is performed by updating the character information to new character information only when the type data of the announced announcement broadcast is higher than the priority of the type data already stored. Since only the information to be transmitted preferentially such as "is stored" can be displayed by the terminal user after returning home, the information to be transmitted most can be surely transmitted to the terminal user.

Further, according to the invention of claim 4,
The terminal device is provided with a voice information storage means for storing voice information, and the voice information output means of the terminal device outputs the voice information stored by the voice information storage means only by the number of reproduction times stored in the reproduction number storage means. By playing back, not only text information but also voice information can be repeatedly broadcast any number of times, all terminal users can be surely broadcast announcements, and the annoyance of the sender can be eliminated. ,
It is possible to quickly perform announcement broadcasting to each terminal user.
