  Next, the security function of base unit 1 will be described. In the security sensor 4, the detection unit 41 is in an abnormal state (for example, a state where an impact exceeding a predetermined threshold is applied to the window glass, a state where the window is open, or a state where the lock is unlocked). Is detected, the sensor control unit 40 causes the wireless transmission unit 42 to transmit a wireless signal (abnormality detection signal). In base unit 1, the wireless signal transmitted from security sensor 4 is received by wireless communication unit 17, and an abnormality detection signal is sent from wireless communication unit 17 to base unit control unit 3. At this time, nothing is performed when the parent device control unit 3 is switched (set) to the non-warning mode. On the other hand, when the mode is switched (set) to the alert mode, the base unit control unit 3 controls the audio processing unit 13 to notify the speaker 12 of the occurrence of an abnormality (for example, “the window glass is broken” ”,“ The window (door) is open ”or“ Voice (window) is not locked. ”And the video display unit 16 and the display unit 21 is displayed to notify the occurrence of abnormality. If the operation input receiving unit 19 of the base unit 1 receives a notification stop operation input while the abnormality occurrence is being notified, the base unit control unit 3 rings the message from the speaker 12 and the video display unit. 16 and the display of the alerting | reporting by the display part 21 are stopped.

  Here, the switching between the warning mode and the non-warning mode in the parent device control unit 3 is performed by operating a warning button (not shown) provided on the housing 23 of the parent device 1 or wirelessly transmitted from the operation device 5. This is performed by receiving a signal (mode switching signal).

  The operating device 5 receives a setting input for a warning mode and a setting input for a non-warning mode and outputs an operation signal corresponding to each setting input, and a radio signal using radio waves as a medium via an antenna 52 Wireless communication unit 51 for transmitting and receiving, display unit 54 formed of a display device such as a liquid crystal display, operating device control unit 50 for controlling each unit, and a synthetic resin molded product formed in a shape and dimensions that are easy to carry It comprises a container body 55 for storing these parts. As shown in FIG. 1, the screen of the display device constituting the display unit 54 is exposed at the upper front of the container 55, and the warning setting button 53 a for setting the warning mode at the lower front of the container 55. And a warning release button 53b for releasing the warning mode (setting to the non-warning mode). That is, when the warning setting button 53a is pressed, the operation input receiving unit 53 receives a warning mode setting input and outputs a warning mode setting operation signal to the controller control unit 50, and the warning release button 53b is pressed. Then, the operation input receiving unit 53 receives a non-warning mode setting input and outputs an operation signal for non-warning mode setting to the operating device control unit 50. And the operating device control part 50 sets the radio | wireless signal (mode switching signal) for setting to the warning mode (switching) according to the operation signal received from the operation input reception part 53, or setting to the non-warning mode (switching). ) Is transmitted from the wireless communication unit 51.

  In base unit 1, radio signal (mode switching signal) transmitted from operation device 5 is received by radio communication unit 17, and base unit control unit 3 is set to a warning mode or a non-warning mode according to the received mode switching signal. At the same time, a radio signal for notifying mode information indicating the mode after setting (after switching) (warning mode or non-warning mode) is transmitted from the radio communication unit 17 to the controller 5. A unique address is independently assigned to each of the parent device 1, the security sensor 4, and the operation device 5, and the transmission destination and the transmission source of the wireless signal are specified using the addresses.

  In the operation device 5, the wireless signal transmitted from the base unit 1 is received by the wireless communication unit 51, and the operation device control unit 50 sets a mode (alert after switching) based on the mode information of the received wireless signal. Mode or non-warning mode) is displayed on the display unit 54. Therefore, the resident who operated the operation device 5 can confirm from the display on the display unit 54 that the parent device 1 has been set to the alert mode or the alert mode has been released. In addition, it is also possible to alert | report the setting condition of warning mode and non-warning mode by mounting a buzzer in the operation device 5 and sounding a buzzer. Here, when the security sensor 4 detects the open / closed state of the window or the locked / unlocked state of the lock, a radio signal transmitted from any of the security sensors 4 by the base unit 1 set in the alert mode. When the (abnormality detection signal) is received, the abnormality detection status of the security sensor 4 from the base unit control unit 3 to the operating device 5, that is, the window is open or the lock of the window or the entrance is not locked. A wireless signal for notifying the shut-down situation may be transmitted from the wireless communication unit 17. Then, the wireless communication unit 51 receives the wireless signal transmitted from the base unit 1 and the controller control unit 50 causes the display unit 54 to display the abnormality detection status (door tightness status) of the received wireless signal. Sometimes, the resident who has operated the operation device 5 can check the door-tight state of the house H by the display on the display unit 54, and as a result, forgetting to close the door can be prevented. It should be noted that a radio signal requesting notification of the abnormality detection status from the operation device 5 may be transmitted to the parent device 1, and the abnormality detection status may be notified from the parent device 1 to the operation device 5 when this request is received. Absent.

  Here, as described in the related art, a metal entrance door 100 is installed in a recent house H, and the switching operation between the warning mode and the non-warning mode using the operation unit 5 is performed in front of the entrance door 100. Since the radio wave transmitted from the wireless communication unit 51 of the operation device 5 is shielded or attenuated by the entrance door 100, there is a possibility that it does not reach the base unit 1 in the house H. Therefore, in this embodiment, a relay device that relays a radio signal (mode switching signal) transmitted from the outside of the house H to the base unit 1 in the house H is installed on the entrance door 100. Furthermore, in this embodiment, the repeater is comprised integrally with the electric lock apparatus 6 installed in the entrance door 100. FIG. Hereinafter, the electric lock device 6 will be described in detail with reference to FIG.

  The electric lock device 6 includes an electric lock 60, an electric lock control unit 61, a wireless communication unit 62, and a pair of antennas 63 and 64 accommodated in a case (not shown). As shown in FIG. Installed inside. The electric lock has a conventionally well-known configuration, and is locked and unlocked by retracting a dead bolt with a motor. The electric lock control unit 61 has a function of driving and controlling the motor of the electric lock 60, and a function of authenticating whether or not the ID information received as a wireless signal matches preset ID information, as will be described later. And when the two ID information match and it is determined that the authentication is possible, the motor is driven to lock or unlock the electric lock 60. The wireless communication unit 62 transmits / receives a radio signal using radio waves as a medium, amplifies a radio signal received by one antenna 63, transmits the radio signal from the other antenna 64, and receives a radio signal received by the other antenna 64. And a function of transmitting from one antenna 63 (relay function). That is, the wireless communication unit 62 and the pair of antennas 63 and 64 constitute a repeater. One antenna 63 is provided inside the entrance door 100 (inside the house H), and the other antenna 64 is provided outside the entrance door 100 (outside the house H).

  Thus, when the resident operates the warning button 53a of the operating device 5 from outside the entrance door 100 when going out, a radio signal (mode switching signal) for setting the warning mode as described above is generated. 5 is transmitted. The wireless signal transmitted from the transmitter 5 is received by the antenna 64 provided outside the entrance door 100 and transmitted from the antenna 63 provided inside the entrance door 100 by the wireless communication unit 62. Then, the radio signal transmitted from the antenna 63 is received by the parent device 1, and the parent device control unit 3 is set (switched) to the alert mode. On the other hand, if the resident operates the warning release button 53b of the operation device 5 from the outside of the entrance door 100 when returning home, the wireless signal (mode switching signal) for setting the non-warning mode as described above is generated. 5 is transmitted. The wireless signal transmitted from the transmitter 5 is received by the antenna 64 provided outside the entrance door 100 and transmitted from the antenna 63 provided inside the entrance door 100 by the wireless communication unit 62. Then, the radio signal transmitted from the antenna 63 is received by the parent device 1, and the parent device control unit 3 is set (switched) to the non-warning mode. However, in order to prevent the base unit 1 from being erroneously switched to the warning mode or the non-warning mode by the radio signal transmitted from the controller 5 operated by the neighbor's resident, unique ID information assigned to each house H is provided. The base unit control unit 3 that has received the mode switching signal included in the mode switching signal authenticates the ID information.

  In the present embodiment, the wireless communication unit 62 of the electric lock device 6 passes the ID information included in the mode switching signal to the electric lock control unit 61, and the ID information received by the electric lock control unit 61 from the wireless communication unit 62. If it is determined that authentication is possible, the electric lock 60 is controlled to lock or unlock. That is, it is possible to simultaneously perform the switching operation between the warning mode and the non-warning mode of the parent device 1 and the locking / unlocking operation of the electric lock 60 with one controller 5. However, a dedicated button for locking and unlocking the electric lock 60 is provided on the front surface of the body 55 of the operation unit 5, and the locking and unlocking operation of the electric lock 60 and the warning mode / non-warning of the base unit 1 are performed. The mode setting (switching) operation may be performed independently. In addition, when transmitting ID information by a radio signal, by encrypting the ID information, the base unit 1 is illegally switched to a non-warning mode by a radio signal transmitted from a device other than the operation unit 5 or an electric lock. It is possible to prevent the device 6 from being unlocked illegally.

  By the way, in the main | base station 1 of this embodiment, since the lighting fixture 200 and the air conditioner 210 in the house H can be controlled by the apparatus control part 22, when the main | base station control part 3 is set to warning mode, for example, If the lighting device 200 is turned off and the air conditioner 210 is stopped by the device control unit 22, it is possible to prevent the lighting device 200 and the air conditioner 210 from being forgotten to be turned off when going out, thereby saving energy. Moreover, if the main | base station control part 3 turns on the lighting fixture 200 by the apparatus control part 22 and drives the air conditioner 210 when it sets to non-warning mode, the lighting fixture 200 will be turned on automatically at the time of going home. In addition, the air conditioner 210 can be automatically operated to improve usability.

  Here, when the operating device 5 is used as a key of the electric lock device 6, each resident (for example, father, mother, child, etc.) needs to carry the operating device 5. At this time, since unique ID information is assigned to each of the plurality of operation devices 5, who is the resident carrying the operation device 5 that is the transmission source of the ID information based on the ID information? Can be determined. And if this resident's discrimination | determination result is utilized, control of the electric equipment by the main | base station 1 can be performed efficiently. For example, the correspondence between the ID information of the operation device 5 and the resident is stored in the storage unit 20 of the base unit 1, and a radio signal (mode switching signal) relayed from the relay device (electric lock device 6) is received. At this time, based on the ID information included in the mode switching signal and the correspondence relationship stored in the storage unit 20, the base unit control unit 3 determines who is the resident who has returned home. On the other hand, the storage unit 20 of the master unit 1 stores the identification codes of the lighting fixture 200 to be turned on and the air conditioner 210 to be operated for each resident, and the master unit control unit 3 stores the identification code in the storage unit 20. With reference to the correspondence relationship between the stored resident and the identification code, for example, when it is determined that the child has returned home based on the ID information, the lighting device 200 in the living room and the child room is turned on and the air conditioner in the child room If it is determined that the mother has returned home based on the ID information, the living room and kitchen lighting fixtures 200 are turned on. If it does in this way, according to the resident who came home, the electric equipment in house H can be controlled appropriately, and energy saving and the improvement of convenience can be aimed at.

  In the repeater (electric lock device 6) in the present embodiment, the radio signal transmitted from the operation device 5 is relayed to the master unit 1 by a radio signal. However, the repeater between the master unit 1 and the repeater is used. The communication method may be a wired communication method, and a wireless signal transmitted from the operation device 5 may be converted into a wired signal by a repeater to perform wired communication with the parent device 1.
