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

  First, terminal registration will be described.

  First, when the registration receiving means 6 is operated in the central processing unit 1, the data communication means 5 enters a standby state waiting for registration data from the terminals 2 to 4. Next, when a battery is inserted into the power supply means 17 of the terminals 2 to 4, the registration request means 19 outputs a signal requesting registration of the terminals 2 to 4 to the control unit 26, and the time measuring means 20 starts timing. . At the same time, the voltage detection means 18 detects the voltage of the power supply means 17, and the voltage data is sent to the control unit 26. Then, the data communication means 16 transmits the voltage data together with the address information of the terminals 2 to 4 to the data communication means 5 of the central processing unit 1. At this time, the LED of the registration display means 23 blinks and a buzzer as the registration notification means 24 sounds to notify that the terminals 2 to 4 are being registered.

  The data communication means 5 of the central processing unit 1 receives the address information and voltage data of the terminals 2 to 4, and the address information of the terminals 2 to 4 is stored and registered in the registration means 7. And the data communication means 5 transmits the registration confirmation signal which confirms that registration was completed with respect to the terminals 2-4. When the data communication means 16 of the terminals 2 to 4 receives this signal, the control unit 26 turns off the LED of the registration display means 23 and stops the buzzer as the registration notification means 24. As a result, the registration display means 23 visually notifies the registration notification means 24 that the registration of the terminals 2 to 4 is completed, and the registration notification means 24 audibly informs the terminal devices 2 on the spot when the battery is inserted into the terminal device 2. 4 registration can be confirmed, which leads to improvement in security and operability.

  In addition, the control unit 26 stores in the nonvolatile storage means 27 that registration has been completed. Since the data in the storage means 27 can be erased only when a reset switch (not shown) is operated, the storage means 27 stores that the registration has been completed when the battery is replaced next time. The registration operation is not repeated.

  On the other hand, if the data communication unit 16 fails to transmit address information and voltage data, or the data communication unit 5 fails to receive, a registration confirmation signal is not returned from the central processing unit 1 to the terminals 2 to 4. If the registration confirmation signal is not returned even when the timing means 20 measures 5 minutes, for example, the control unit 26 switches the LED of the registration display means 23 from blinking to lighting, and switches the buzzer of the registration notification means 24 to an error sound, Informs that the terminal registration failed. When another 30 seconds elapse, the LED of the registration display means 23 is turned off and the buzzer of the registration notification means 24 is stopped. As a result, when the terminal units 2 to 4 do not receive the registration confirmation signal from the central processing unit 1 even when the time measuring unit 20 measures the predetermined time, the registration display unit indicates that the registration of the terminal units 2 to 4 has failed. 23 is visually informed and the registration notification means 24 is audibly informed so that it is possible to confirm that the registration of the terminals 2 to 4 has failed on the spot when the batteries are inserted into the terminals 2 to 4. The battery can be turned on again to register again.

  Next, the voltage data request of the power supply means 17 of the terminals 2 to 4 will be described.

  The control unit 15 of the central processing unit 1 transmits the voltage data received together with the address information when registering the terminals 2 to 4 to the voltage request interval determining means 8. Based on this voltage data, the voltage request interval determining means 8 determines an interval for requesting the terminals 2 to 4 to transmit the next voltage data. For example, when the voltage data is 4.0 to 4.5V, it is 24 hours, when it is 3.5 to 4.0V, 12 hours, when it is 3.0 to 3.5V, it is 6 hours. The request interval is determined to be short. The determined request interval is transmitted to the voltage request means 9, and the voltage request means 9 outputs a signal at this request interval, and the data communication means 5 provides a code for requesting the terminal devices 2 to 4 to transmit voltage data. Send. The data communication means 16 of the terminal device 2 receives a code requesting transmission of voltage data, and the voltage detection means 18 detects the voltage of the power supply means 17. The data communication means 16 transmits this voltage data together with its own address information to the central processing unit 1. The central processing unit 1 receives this data, and can grasp the voltage of the power supply means of which terminal unit at an optimum interval according to the voltage data.

  When the received voltage data is smaller than a predetermined value (for example, 3.0 V), the terminals 2 to 4 that require battery replacement and a battery replacement mark are displayed on the liquid crystal display unit of the battery replacement display means 10, and the battery For example, the voice output unit serving as the exchange notification means 11 gives a voice notification "Please replace the battery of the terminal 2". Thereby, in the central processing unit 1, the battery replacement time of the terminals 2 to 4 can be visually or audibly understood, and the batteries of the terminals 2 to 4 can be replaced. Further, the central processing unit 1 can grasp the next voltage data at shorter intervals as the received voltage data is smaller, and can accurately determine the timing of battery replacement.

  Further, the central processing unit 1 transmits a signal for urging the battery replacement to the terminals 2 to 4 through the data communication unit 5. The data communication means 16 of the terminals 2 to 4 receives this signal, and the control unit 26 turns on the LED of the battery replacement display means 21 and outputs the buzzer of the battery replacement notification means 22. Accordingly, it is possible to visually or audibly know the necessity of battery replacement in the terminals 2 to 4 as well. When the battery is replaced, the LED of the battery replacement display means 21 is turned off, and the buzzer of the battery replacement notification means 22 stops outputting. By this battery exchange, the data communication means 16 transmits its address information and voltage data detected by the voltage detection means 18 to the central processing unit 1, and the central processing unit 1 grasps the voltage data after battery replacement. Thereby, for example, when an old battery is erroneously inserted and the voltage data is smaller than a predetermined value (for example, 3.0 V), the LED of the battery replacement display means 21 is turned on by a signal from the central processing unit 1, and a battery replacement notification is made. Since the buzzer of the means 22 sounds, it can be grasped that the battery is old, and can be replaced with a new battery on the spot.

  Next, the operation of intrusion detection will be described.

  The warning operation is started by setting the warning mode by the setting unit 14 of the central processing unit 1 or by the operation input means 29 of the terminal device 4 when the user goes out or goes to bed at night. When the window or door in which the terminal device 2 is installed is opened during the warning operation, the intrusion detection means 25 operates, and a signal indicating occurrence of an unsteady state is output to the data communication means 16 of the terminal device 2. Upon receiving this signal, the data communication means 16 sends a signal to the data communication means 5 of the central processing unit 1. This signal first sequentially transmits the address information of its own terminal and a status code indicating that an intrusion has occurred. In the central processing unit 1, the data communication means 5 of the central processing unit 1 receives this transmission signal, determines which terminal the signal is from, and further receives a signal indicating that an intrusion has occurred. Based on this signal, the public line connection means 12 operates, and the external line connection unit 13 notifies the name of the location where the intrusion has occurred in the telephone or mobile phone outside the house corresponding to the telephone number registered in advance and the fact that the intrusion has occurred. Report a voice message.

  Next, an operation related to an emergency call will be described.

  The user operates the emergency call means 28 of the terminal device 3 when an intrusion occurs even when at home, or when the user's physical condition suddenly changes and the outside needs to be contacted. The address information of the terminal device 3 and the status code of the occurrence of an emergency are transmitted to the central processing unit 1, and the corresponding voice message is reported to an external telephone or mobile phone by the public line connection means 12 based on this information. Can do.

  Next, operations related to remote operation will be described.

  When the user operates the operation input means 29 of the terminal device 4, the address information of the terminal device 4, the operation input content, and the operation code corresponding to the warning start / stop command are transmitted to the central processing unit 1. Based on this, the central processing unit 1 starts and stops vigilance.

  As described above, in the embodiment of the present invention, the registration accepting means 6 of the central processing unit 1 is allowed to accept registration of the terminals 2 to 4, and the power supply means 17 of the terminals 2 to 4 is connected to the power supply means 17. When the battery is inserted, the registration request means 19 outputs a signal for requesting registration of the terminals 2 to 4, and the data communication means 16 detects the voltage data detected by the voltage detection means together with the address information of the terminals 2 to 4. Is transmitted to the central processing unit, and the address information of the terminal is registered in the central processing unit 1, so that the terminal can be prevented from being erroneously registered or forgotten to be registered. Registration can be done automatically.

  Moreover, the central processing unit 1 can grasp the initial state of the voltage of the power supply means 17 of the terminals 2 to 4. Based on this voltage, the voltage request interval determining means 8 determines the interval for requesting the transmission of the voltage data of the power supply means 17, and the voltage requesting means 9 requests the terminals 2 to 4 to transmit the voltage data. The central processing unit 1 can grasp the voltage data at an optimum interval according to the voltage of the power supply means 17.

  In the present embodiment, the central processing unit 1 is provided with both the battery replacement display means 10 and the battery replacement notification means 11, but may be either as required.

  Moreover, although both the battery replacement display means 21 and the battery replacement notification means 22 are provided in the terminals 2 to 4, they may be either as required.

  Moreover, although both the registration display means 23 and the registration alerting | reporting means 24 are provided in the terminals 2-4, you may be either as needed.

  Further, the number of terminals is four, and the number is not particularly limited. Any number of terminals may be used as long as the address information and status code of the terminal can be specified.

  Moreover, although the intrusion detection means is constituted by a reed switch corresponding to the movement of the magnet of the movable part, the same effect can be obtained even if a human body sensor such as a pyroelectric infrared sensor is used.

  Further, the display means may be a screen display other than the LED, and the notification means may be voice guidance other than the buzzer.
