P) and the like, each of which is connected to the head end 18 via a modulator (1) 21 and a modulator (2) 22 and sends out a background video signal.

FIG. 3 is a block diagram of the karaoke terminal device 4. The karaoke terminal device 4 includes a control unit 31 as the main body unit 8, a transmission / reception modem 32 and a transmission / reception control unit 33 for receiving signals such as musical tone / lyric information other than images sent by the coaxial cable 5, signals such as emergency notifications, and the like. A tuner 34 for receiving a video signal, a tone control section 35 for outputting an audio signal, a display control section 36 for inputting an analog video signal reproduced by the tuner 34 and outputting a video signal, various data and input A memory 37 for storing reserved music numbers and the like and an operation panel 38 for inputting reserved music by keys are provided.

The display control unit 36 is composed of a video graphic processor having a function of superimposing lyrics and messages on the background video. The memory 37 stores data for generating image information for making an emergency notification when the control unit 31 receives an emergency notification signal, and data for generating a musical sound, lyrics, etc. based on the received information. . In the present embodiment, an example in which the tuner 34 reproduces an analog video is shown, but a decoder for decoding compressed video data may be used instead of the tuner 34.

The operation of the system having the above-described structure will be described. When the receiver 2 receives a fire alarm signal from the sensor 1, it sends a notification output 2a to the central controller 3. Server 12
When receiving the notification output 2a from the notification input unit 13, the controller sends an emergency notification signal to the coaxial cable 5 through the transmission / reception control unit 16. Upon receiving this emergency notification signal, the karaoke terminal device 4 stops the karaoke performance and uses the data for generating the image information for emergency notification stored in the memory 37 to cause the display control unit 36 to display the image. The information is generated and displayed on the television 9, and an emergency call is made by voice from the speaker 10.

On the other hand, when the fire is extinguished or the emergency notification is a false alarm, the server 12 outputs an emergency cancellation notification signal, and when the karaoke terminal device 4 receives this, an emergency cancellation notification operation is performed. Here, the signal of the emergency notification and the cancellation notification sent from the server 12 does not need to include the data for displaying the image, and may be a signal of the emergency notification / cancellation notification. Therefore, it is not necessary to provide the central control device 3 side having the server 12 with equipment such as a laser disk and a video deck for generating the image of the emergency notification, and an image modulator.

The operation of the karaoke terminal device 4 will be described in detail with reference to the flowchart of FIG. The control unit 31 checks whether or not there is an emergency notification signal in the reception information input through the transmission / reception control unit 33 (S1), and if there is no emergency notification signal, checks whether there is a reserved song for karaoke performance. (S
2) If there is no reserved song, the process returns to S1, and if there is a reserved song, the leading song number is read from the reserved song number memory and written into the currently playing song number memory (S3), and the song data in the same memory is stored in the central controller. 3 is read from the storage device 15 and the performance is started (S4). If there is no emergency notification signal during the performance (S5, NO), it is checked whether the performance of the music is completed (S6). If the performance is completed (S6, YES), the process returns to S1. If there is an emergency notification signal during the performance (S5, YES), the performance of the song is stopped (S7) and an emergency notification guide is displayed on the screen (S).
8). The video signal for this emergency notification guidance is generated by the display control unit 36 using the image information data of the memory 37 for making an emergency notification.

After that, if there is an emergency cancellation notice (S9, Y
ES), and an emergency cancellation guide is displayed on the screen (S10).
Next, if there is a key input by the operator to instruct resumption of operation (S11, YES), it is checked whether or not there is a currently playing music (S12). Return to. Further, if there is an emergency notification signal in S1, the guidance of the emergency notification is displayed on the screen (S13), and thereafter, the same processing as S9 and S10 is performed in S14 and S15, and the operation restart is instructed in S16. Wait for key input and return to S1. Note that the emergency notification and the cancellation notification are given by voice as well as the image display. Further, even if the central control device 3 side is damaged by the fire, the terminal device 4 side can continue the fire notification.

FIG. 5 is a block diagram of the entire system according to the second embodiment. In this system, the central control device 3 shown in the first embodiment is used as a server for transmitting various information signals to each of a plurality of karaoke terminal devices 4 to control the entire system, and a notification output 2a from the receiver 2. This is a configuration in which the receiving terminal for receiving is independent. Each karaoke terminal device 4 is shown in FIG.
The same as Since the basic operation of this embodiment is the same as that of the first embodiment, its explanation is omitted.

Further, the central control unit 3 has a communication means connected to an external device (not shown), and when a fire detection signal is received, the communication means is used to inform the external device that a fire has occurred. It may be configured as follows. With this configuration, the karaoke terminal device 4 can be notified of the fire at the same time, and the fire station, the adjacent building, the disaster prevention center, the owner of the building, and the like can also be notified of the fire.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. For example, in the above embodiment, the central control device 3 and the karaoke terminal device 4 are shown as separate bodies. These may be integrated. Furthermore, when the present invention is applied to a karaoke centralized control device as described above, the karaoke terminal device is generally used in a closed room where sound is shielded, and the user may not be able to hear an emergency call outside the room. Since many are preferable, the present invention is not limited to this, and can be applied to a system having a function of displaying an image on the terminal device side.

[0022]

As described above, according to the present invention, in the fire alarm system capable of outputting the emergency notification information of a fire or flame as an image, the image output is performed by using the image display function originally provided in the terminal device. Therefore, it is necessary to prepare a transmission device such as a video reproducing device such as a laser disk or a video deck or a video modulator for generating an image for emergency notification on the side of the central control device that receives the fire detection signal. In addition, it is possible to provide an inexpensive system that requires little new capital investment.
