Next, its operation will be explained. A case will now be described in which the first abnormality detection device 2 detects an abnormality, such as a gas leak, when the TV 1 is in an off state. First, in response to a detection signal from the gas leak sensor 2b, the television signal generator 3 generates a television signal of images and sounds corresponding to the gas leak, and inputs the television signal to a predetermined security channel of the TV 1.
Since TV 1 is off, "0" is stored in channel memory 12. When the first abnormality detection device 2 detects the occurrence of a gas leak abnormality, a first abnormality detection signal is applied to the signal transmitter 5, which generates a digital signal corresponding to the first detection signal with a high degree of urgency. , and is sent to the transmission line 6 as a serial packet signal. The transmitter/receiver 7 receives this signal and transmits it to the transmission module 8, where it is determined whether or not there is an error in the packet signal, and it is converted into a parallel signal and applied to the decoder 9 of the processing device 20.
The decoder 9 decodes this parallel signal and outputs a signal to the terminal 9Ao corresponding to the occurrence of the first abnormality. This output is input and stored in the abnormality type memory 10, and the comparison device 11 compares the degree of urgency with abnormalities already stored in the memory 10. However, since this is the first abnormality occurrence, the data to be compared is not stored. Therefore, the comparator 11 outputs a signal to the terminal 11A corresponding to the gas leak abnormality, and the signal is applied to the channel selector 13. Channel selector 1
3, in response to the input of this signal, a signal is sent to terminal 13b.
A TV switch-on signal is outputted to the terminal 13c, and a TV audio amplification signal is applied to the TV1, and at the same time, from the output terminal 13a to the channel switch 14 of the TV1.
, outputs the channel number signal corresponding to the first abnormality, turns on the power of TV1, increases the audio volume, selects the security channel corresponding to the first abnormality, and generates a television signal. The image corresponding to the gas leak from device 3 is displayed on TV1.
Display on CRT and generate audio at high volume through speakers. In this way, the occurrence of a gas leakage abnormality is automatically notified.

Therefore, the TV viewer who learned of the gas leak operated the keypad 16 to send a signal to close the gas main valve, and the encoder 17 transmitted the signal to the transmission module 8, which had created a parallel packet signal corresponding to the signal. , is converted into a serial packet signal and sent from the transceiver 7 to the signal receiver 18 via the transmission line 6. The signal receiver 18 controls a controlled device 19, for example, a gas main valve, in response to this received signal, and closes it.

When the abnormality is removed in this way, the sensor 2b of the abnormality detection device 2 detects that the gas leak has been removed.
The signal transmitter 5 generates a digital signal corresponding to the first abnormality cancellation, and the first abnormality cancellation signal is transmitted to the decoder 9 via the transmission line 6, the transceiver 7, and the transmission module 8. , is decoded here and an output is generated at the output terminal 9An. This output erases the data on the occurrence of the first abnormality stored in the abnormality type memory 10, and all the stored contents are cleared. In response, the output terminal 10R is output, whereby the contents of the channel memory 12 are checked and input to the channel selector 13. Since "0" is stored in the channel memory 12, the channel selector 13 sends the TV off signal to the output terminal 13b and the TV off signal to the output terminal 13c.
Outputs TV audio reduction signal. By this TV
1 is turned off and returns to the state before the abnormality occurred.

The above was an explanation when the initial state of TV1 was off, but if the above abnormality occurs while TV1 is on, the channel memory 12 will store the currently selected TV channel as the selected channel. Other than the fact that it is read out from the readout terminal 15 and stored,
Similar to the above, the type of the transmitted abnormality is stored in the abnormality type memory 10, and the channel selector 13 selects a security channel to display the abnormality. When the abnormality is cleared, the contents of the abnormality type memory 10 are cleared, the channel memory 12 is checked, and the channel stored therein is returned to the same state as the initial state.

Next, TV1 is on and there is a visitor coming.
A case will be described in which a visitor signal indicating that the TV door intercom device 4 has been activated is transmitted as a second abnormality detection signal, and a first abnormality detection signal with a higher degree of urgency is further transmitted. normal
When TV broadcasting is selected, for example, channel 1 is selected and "1" is stored in the channel memory 12, when the above-mentioned visitor signal is transmitted, the decoder 9 decodes it and outputs it to the output terminal 9Bo. The abnormality type memory 10 stores the signal, and a signal is output to the terminal 11B corresponding to the visitor signal of the comparator 11, the channel selector 13 outputs the TV door phone channel number, the TV 1 selects the channel, and the TV door phone The image and voice of the visitor from the device 4 is played. At this time, the first abnormality detection device 2
If the detects another highly urgent abnormality, it is transmitted and decoded by the decoder 9, and an output is generated at the terminal 9Ao, for example, which is stored in the abnormality type memory 10, and the comparator 11 has already read the memory. The contents stored in 10 and the degree of urgency are compared. Although visitor data has already been stored in the memory 10, since the newly occurring abnormality has a higher degree of urgency, the output terminal 11B of the comparison device 11
The signal is erased, a signal is generated at the output terminal 11A,
outputting the security channel number assigned to the first abnormality from the channel selector 13;
TV 1 is switched from the TV door main channel to the security channel, and the image is displayed and the audio is played. Next, when this abnormality is canceled, the cancellation signal is decoded by the decoder 9 and outputted to the terminal 9An, and the data of this abnormality stored in the abnormality type memory 10 is erased. At this time, if the visitor cancellation signal had come first, the visitor data in the memory 10 would have been erased, so all contents would be cleared and the terminal 1
The contents of the channel memory 12, that is, channel 1, are changed to the channel selector 13 by the output from 0R.
, which returns the TV to its original channel. However, if the visitor cancellation signal has not been received, the abnormality type memory 9 contains only visitor data, and the output of the output terminal of the comparator 11 changes from 11A to 11B. Therefore, the channel selector 13
The TV door main channel number will be output from
TV1 selects the TV door main channel. Next, when the visitor cancellation signal is transmitted, all the stored contents of the abnormality type memory 10 are cleared, and the channel memory 12 is checked by the output of the terminal 10R.
The channel "1" response stored therein is transmitted to the channel selector 13, and TV1 is switched to the original channel.

In addition, even if a visitor signal with a low priority comes when the first abnormality with a high degree of urgency occurs, the abnormality type memory 10
The output of the comparison device 11 remains unchanged, and no new channel selection operation is performed. If the visitor status is still present when the abnormality is cleared,
TV door channel channel is selected.

Note that when the first abnormality occurs, if another abnormality with the same degree of urgency occurs, for example, a gas leak occurs,
In the next case where a fire occurs, the TV signal generated by the TV signal generator 3 is simply switched to images and sounds indicating the occurrence of two abnormalities, and no channel switching operation is performed.

In this manner, when an abnormality occurs, a channel corresponding to the abnormality with a high degree of urgency is automatically selected, and when the abnormality is removed, the channel is automatically returned to the original channel.

The above describes switching between the two abnormality display channels, the first abnormality with the highest degree of urgency and the TV doorbell, but there are also channels for indoor calls, video calls, etc., and these also have different degrees of urgency. It is also possible to switch between three or more abnormality display channels.

Furthermore, although the operation of the processing device 20 has been described as a device configured with hardware, it is also possible to operate the processing device 20 or a part thereof by a program of a microcomputer.

[Effects of the Invention] Since the present invention is configured as described above, the occurrence of an abnormality can be automatically and quickly displayed on television and alerted by voice without requiring any operation. This has the effect of allowing high-level abnormalities to be known preferentially. Furthermore, since it is possible to incorporate visitor notifications and the like with low urgency into the system as abnormalities, it has the advantage of further expanding the scope of application.
