The audio output unit 25 amplifies the audio signal received and demodulated by the audio communication unit 23.

  About the monitoring system comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in the flowchart of FIG. 4, the control unit 16 of the central processing unit 1 sets the installation locations of the terminals 2 to 6 displayed on the display unit 15 by the installation location setting means 12 in step 26. And memorize it. For example, if “terminal 2-living room”, “terminal 3-bedroom”, “terminal 4-study”, “terminal 5-child room 1”, “terminal 6-child room 2” are set. The central processing unit 1 can recognize where the terminals 2 to 6 are installed.

  Next, in step 27, when the central processing unit 1 receives the unsteady signal from the terminals 2 to 6 by the terminal selection means 9, a notification signal including information on the unsteady state is transmitted and external notification is made. Select and set the terminal you want to use. At this time, it is assumed that the terminal device 3 (bedroom), the terminal device 4 (study), and the terminal device 5 (child room 1) are selected as the terminal device to be notified.

  Next, in step 29, the importance setting means 10 sets the importance of the terminal that transmits the monitor start signal. At this time, it is assumed that the terminal 3 (bedroom) is set to be more important than the terminal 4 (study).

  Next, in step 30, the time setting means 14 sets the time measured by the time measuring means 13, that is, the monitoring time from when the central processing unit 1 receives the monitor start signal. For example, assume that it is set to 10 minutes.

  When the warning operation is started in step 31, the central processing unit 1 enters a standby state in which the information regarding the unsteady state from the terminals 2 to 6 is awaited in step 32.

  Now, assuming that an intruder has occurred and the intruder detection unit 17 of the terminal device 2 has detected the intruder, the terminal device 2 transmits information on the unsteady state to the central processing unit 1 by the data communication means 18. When the data communication means 7 of the central processing unit 1 receives the information about the unsteady state from the terminal device 2, the installation location setting means 12 is connected to the terminals 3 to 5 selected by the terminal device selection means 9 in step 33. A notification signal including the installation location information set in is transmitted.

  The terminals 3 to 5 that have received the notification signal from the central processing unit 1 notify the voice data stored in the voice data storage unit 20 from the notification means 21 to the outside from the information of the received notification signal. For example, when it is set that the terminal device 2 is installed in the living room, a sound such as “An abnormality has occurred in the living room” is notified from the terminal devices 3 to 5.

  When a user who has recognized an abnormality operates the monitor start means 22 through the voice notification from the terminals 3 to 5, the data communication means 18 transmits a monitor start signal for starting the voice monitor to the central processing unit 1. .

  In step 34, the central processing unit 1 waits for a monitor start signal from a terminal device other than the terminal device 5 set by the acceptance refusal setting means 11, that is, the terminal device 3 or the terminal device 4, and the data communication means 7 When the monitor start signal is received from the device 3 or the terminal device 4, in step 35, the time measuring means 13 is operated to start time measurement.

Sent to the device 1.

  In step 40 a, the voice communication means 8 of the central processing unit 1 receives the voice signal transmitted from the voice communication means 23 of the terminal device 2 and transfers it to the terminal device 3. Then, the voice output means 25 of the terminal 3 amplifies the voice signal received and demodulated by the voice communication means 23 and starts voice monitoring around the terminal 2.

  In step 41a, it is determined whether the time measuring means 13 has timed 10 minutes set by the time setting means 14, and when 10 minutes have been timed, the data communication means 7 monitors the terminal device 2 and the terminal device 3 in step 42. Send a signal to end.

  When the terminal 2 receives a signal to end the monitoring, the voice input means 24 is stopped, the data communication means 18 stops transmitting the voice signal, and when the terminal 3 receives a signal to end the monitoring, the voice output means 25 is turned off. Stop and end monitoring.

  On the other hand, if the monitor start signal is not received from the terminal device 3 and the monitor start signal is received from the terminal device 4 in step 38a, the data communication means 7 of the central processing unit 1 detects the intruder in step 39b. A monitor start signal is transmitted to the terminal 2 that has performed.

  When the data communication means 18 of the terminal device 2 receives this monitor start signal, the sound input means 24 collects the sound around the terminal device 2, and the collected sound is modulated by the sound communication means 23 for central processing. Sent to the device 1.

  In step 40 b, the voice communication means 8 of the central processing unit 1 receives the voice signal transmitted from the voice communication means 23 of the terminal device 2 and transfers it to the terminal device 4. Then, the voice output means 25 of the terminal 4 amplifies the voice signal received and demodulated by the voice communication means 23 and starts voice monitoring around the terminal 2.

  In step 41b, it is determined whether the time measuring means 13 has timed 10 minutes set by the time setting means 14, and when 10 minutes have been timed, the data communication means 7 monitors the terminal device 2 and the terminal device 3 in step 42. Send a signal to end.

  When the terminal 2 receives a signal to end the monitoring, the voice input means 24 is stopped, the data communication means 18 stops transmitting the voice signal, and when the terminal 3 receives a signal to end the monitoring, the voice output means 25 is turned off. Stop and end monitoring.

  Next, in step 43, it is determined whether the warning operation has been released. If it has been released, the warning operation is terminated.

It is possible to know the detailed situation such as whether or not, and to deal with it according to the situation of the intrusion site.

  In addition, when an abnormality occurs, it is possible to select whether to notify the abnormality occurrence for each terminal. For example, if you do not want to wake up young children who are sleeping, they are installed in the children's room By not selecting the terminal, it is convenient because no notification is given from the terminal in the child room.

  In addition, the acceptance refusal setting means 11 can prevent a monitor start signal from being received from a specific terminal, so that, for example, the occurrence of an abnormality is notified from a terminal in a child's room with an older child. However, monitoring is prohibited by the acceptance refusal setting means 11 when it is not desired to notify the detailed situation of the intrusion site.

  Also, since the importance setting means 10 can set the importance of the monitor start signal relative to other terminals for each terminal, for example, the terminal installed in the bedroom rather than the terminal installed in the study It is possible to give priority to terminals such as priority, and when the central processing unit receives monitor start signals from multiple terminals, an abnormality was detected for a terminal set with a higher importance. It is possible to transfer an audio signal around the terminal and monitor it with a highly important terminal.

  In addition, the time to be monitored by the time setting means 14 can be set in advance according to the user's preference. By monitoring the time set by the time measuring means 13, the monitoring is terminated without any operation. be able to.

  In this embodiment, since the intrusion detection unit 17 of the terminals 2 to 6 is provided with a reed switch, an unsteady signal indicating that an intruder has been generated when a window or door is opened or closed is transmitted. In addition, when the intrusion detection unit 17 detects a human body with a pyroelectric sensor, a non-stationary signal, that is, a non-stationary signal that an intruder has occurred is transmitted.

  In this embodiment, wireless is used as a communication medium. However, any of the communication media such as wired communication using a dedicated line, power line carrier communication, infrared communication, and optical fiber communication has the same effect. It is.
