The abnormal state detection automatic notification and image confirmation system of the home automation according to the present invention is connected to a telephone line as shown in FIG. 1 and a bell signal to the bell signal generation circuit 1 which generates a bell signal through the speaker 21. Connect the sensing circuit 2, connect the telephone line connection circuit 20 to the telephone line, and connect the DTMF (Dual-tone Multifrequency) reception and generation circuit 3 to the telephone line connection path 20, and receive and generate the DTMF. The voice signal line connection circuit 7 is connected to the circuit 3 and the telephone line connection circuit 20, and the voice and sound generation circuit 5 is connected to the speaker 21 and the voice signal line connection circuit 7. The control circuit 8 is connected to the sound generating circuit 5, the DTMF receiving and generating circuit 3, and the bell signal detecting circuit 2 and the telephone line connection circuit 20, and a key input circuit to the control circuit 8 is provided. (4) to connect the video signal to the telephone line connection circuit 20 and the control circuit (8) The furnace 6 is connected, and the abnormal state detection signal processing circuit 11 is connected to the control circuit 8, and the abnormal state detection circuit 15 is connected to the abnormal state detection signal processing circuit 11. The video signal recording circuit 10 to the video signal recording circuit 10, and the video signal recording circuit 10 to the video signal recording circuit 10, and the video signal connecting circuit 6 to the video signal recording circuit 10; And a video recording signal reproducing circuit 14 to the control circuit 8, and a camera signal selecting circuit 13 to the control circuit 8, the video recording signal reproducing circuit 14, and the video signal processing circuit 9. And a plurality of cameras 16 to 18 to the camera signal selection circuit 13 and a power supply circuit 19 for supplying power to each of the circuits.

In the abnormal state detection automatic notification and image confirmation system of the home automation configured as described above, the operation when an abnormal state occurs is as follows.

First, a telephone number for notifying when an abnormal condition occurs using the key input circuit 4 and a password for its use are input.

When the abnormal state detection circuit 15 detects an abnormal state, the abnormal state detection signal is sent to the abnormal state detection signal processing circuit 11 and the signal is recognized by the control circuit 8 in the abnormal state detection signal processing circuit 11. The signal is converted into a possible signal and sent to the control circuit 8. Under the control of the control circuit 8, the voice and sound generating circuit 5 generates a voice suitable for the situation and sends the voice signal to the voice signal line connection circuit 7 while ringing through the internal speaker 21. The control circuit 8 connects the telephone line connection circuit 20, and sends out the abnormal state automatic notification telephone number previously input from the DTMF receiving and generating circuit 3, and first receives the voice signal line connecting circuit 7. In order to send the sent audio signal through the telephone line and send the video signal, it sends out the frequency prescribed by the terminal for a certain time and waits for the signal that the designated pressure paper is ready for reception. And alternately transmit and receive images. If the ready signal does not match, the other party determines that there is no receiving device and continues to transmit only voice.

In order to transmit the video signal, the camera signal selection circuit 13 selects the signals of the cameras 16 to 18 and sends them to the video signal processing circuit 9 according to the control of the control circuit 8. ) Processes the signal from the camera sent from the camera signal selection circuit 13 and sends it to the telephone line and the video signal recording circuit 10 to which the video signal connection circuit 6 is connected. The video recording circuit 10 processes the video signal. The signal output from the circuit 9 is recorded at a predetermined time interval designated by the user, and when a specified subscriber wants to select and view a signal of a specific camera while receiving an image, it can be received by operating a key of a designated DTMF telephone. In other words, if you press (*) key of DTMF phone, camera signal being transmitted will continue to be transmitted, and if you press (#) key, each camera signal will be circulated again. The number of cameras should be specified in advance by the user using the key input circuit 4. The video signal recorded in the video signal recording circuit 10 can be replayed through the video recording signal playback circuit 14 by pressing the designated playback button.

To make a video call to check the situation inside, call first. Then, the bell signal detecting circuit (2) detects the bell signal and sends it to the control circuit (8). The control circuit (8) counts how many rings the bell has made. A message is output through the voice signal line connection circuit 7 and a message for inputting a password through the voice signal line connection circuit 7, and the message is output after the bell rings 13 times when it is not set to go out mode. After the password input message is output, if the password is pressed externally, the control circuit 8 interprets the signal input through the DTMF receiving and generating circuit 3, and turns on the video signal connection circuit 6 if it matches the password previously input. The signal output from the video signal processing circuit 9 is output to the telephone line through the video signal connection circuit 6, and the telephone is disconnected when the password pressed outside the previously input password is different.

When the image is received by external operation, you can select or cycle through the camera signal by operating the (*) and (#) keys. By using the video recording signal reproducing circuit 14, the signals from the cameras 16 to 18 can be selected and viewed from the inside, and can also be used for internal monitoring.

When the key for operating the monitor is pressed to monitor the signal from the cameras 16 to 18 inside, the signal of the cameras 16 to 18 is selected in accordance with the control of the control circuit 8 in the camera signal selection circuit 13. To the video signal processing circuit 9 for processing, and the signal processed by the video signal processing circuit 9 is sent to the video signal recording circuit 10, and the recorded video signal is sent to the video recording signal reproducing circuit 14. Is played.

The present invention is constructed and operated as described above, unlike a conventional video telephone, in which two terminals do not have a button operation with each other, the video signal can be connected to a telephone network by combining video control technology with video transmission. In addition, by using the video receiving device, you can see the situation where you need at any place and can maximize the use effect by connecting with the video.
