  The anomaly reporting unit 215 is set when the guard mode of the parent household area, the child household area, or the common area is set to a state of reporting such as a guarded state or a self-guarded state, that is, a guard mode storage unit for the parent household area 212, when a security state or a self-security state is stored in the security mode storage unit 213 for the child household area or the security mode storage unit 214 for the common area, the sensors 201a to 201n and the sensors 203a to 203n installed in the area Alternatively, when a detection signal is output from the sensors 207a to 207n, the abnormality detection unit 217 detects this and indicates that an abnormality has been detected in the monitoring center 130 or a mobile phone held by the user when going out. report.

  Further, in this embodiment, when the detection signal is output from the sensors 207a to 207n in the common area, the abnormality notification unit 215 detects this by the abnormality detection unit 217 and detects the speaker 223 of the controller 220 in the parent household area or Notify that an abnormality has been detected from the speaker 233 of the controller 230 in the child household area.

  The timer setting unit 216 is stored by the security mode switching unit 211 in the current security mode of the parent household area stored in the parent household area security mode storage unit 212 or in the security mode storage unit 213 for the child household area. When the current security mode of the child household area is switched to the security state or the self-security state, the time measurement of the exit timer for setting a predetermined timer time is started. While the exit timer is counting, even if an abnormality is detected in the parent or child household area that has been switched to the guarded state or the self-guarded state, and in the common area, the abnormality reporting unit 215 cancels the detection signal and is useless. Avoid reporting or alerting.

  For example, assuming that the user in the parent household area sets the parent household area in the guarded state and goes out through the common area, the user goes out through the common area after performing the operation to set in the guarded state. By setting the exit timer time based on the time it takes to complete the operation, the security mode of the common area is set to the security mode state in which the user in the child household area reports the security status or the self-security status. Even if it is a case, it can prevent that an unnecessary report or alerting | reporting will be performed. At this time, the user in the parent household area only needs to perform an operation to set the security mode of the parent household area to the security state or the self-security state without worrying about the security mode of the common area.

  In addition, the timer setting unit 216 is set to a security mode state in which the current security mode of the common area stored in the common area security mode storage unit 214 reports or reports a security state or a self-security state. When an abnormality (the presence of a person, opening / closing of a door, etc.) is detected in the common area by the sensors 207a to 207n installed in the common area, the time measurement of the entrance timer for setting a predetermined timer time is started. . While the entrance timer is counting, a detection signal based on the abnormality detection is suspended so that unnecessary notification or notification is not performed when a user in the parent household area or the child household area that has returned home is detected. When the security mode of the parent household area or the child household area is switched to the security release state before the predetermined timer time elapses, or when the security mode of the common area is switched to the security release state, the abnormality notification unit 215 The detection signal that has been put on hold is canceled, and if the security mode is not switched before the predetermined timer time elapses, a notification that an abnormality has been detected is issued.

  For example, assuming that a user in the parent household area returns home from the outside, moves to the parent household area through the common area, and switches the parent household area to the security release state, the user returns home and enters the common area. By setting the admission timer time based on the time from moving to the parent household area and switching the parent household area to the security release state, the user in the child household area sets the security mode of the common area to the security state or Even when it is set to the security mode state in which the notification or notification of the self-security state or the like is performed, it is possible to prevent unnecessary notification or notification from being performed. At this time, the user in the parent household area only needs to perform an operation for setting the security mode in the parent household area to the security release state without worrying about the security mode in the common area.

  When the abnormality detection unit 217 detects an abnormality in the common area, the output unit 218 outputs a timer sound notifying that someone has entered the common area to the parent household area or the child household area. In this case, since a timer sound is output every time someone enters the common area, for example, it is preferable to play a melody or the like with good ears as the timer sound.

  The controller 220 is installed on the parent household area side, and performs control for a guard mode setting operation or the like of the parent household area or the common area from a user in the parent household area. In addition, you may enable it to perform security mode setting operation of a child household area with the controller 220. FIG. The controller 220 further mainly includes an operation display unit 221, a microphone 222, and a speaker 223.

  The operation display unit 221 is, for example, a touch-input type liquid crystal screen that displays various setting screens for the user and accepts input of the security mode in the parent household area or the common area by the user in the parent household area. Furthermore, the user receives an input of the security mode in the child household area while in the parent household area.

  The microphone 222 acquires the voice uttered by the person in the parent household area, and the speaker 223 outputs the transmitted voice or the like to the parent household area.

  The sub-controller 230 is installed on the side of the child household area, and performs control for a security mode setting operation or the like of the child household area or the common area from a user in the child household area. Note that the sub-controller 230 may perform a security mode setting operation for the parent household area. The sub-controller 230 further mainly includes an operation display unit 231, a microphone 232, and a speaker 233.

  The operation display unit 231 is, for example, a touch-input type liquid crystal screen, and receives an input of the security mode in the child household area or the common area by the user in the child household area. In the meantime, input of the security mode in the parent household area is accepted.

  The microphone 232 acquires the voice uttered by the person in the child household area, and the speaker 233 outputs the transmitted voice or the like to the child household area.

  Next, the security mode setting process by the security device 110 according to the present embodiment configured as described above will be described. FIG. 3 is a flowchart showing a procedure for setting the security mode by the security device 110 in the parent household area. The procedure for setting the security mode by the security device 110 in the child household area is the same.

  First, when the user in the parent household area sets the security mode, a security mode setting screen is displayed on the operation display unit 221 of the controller 220 (step S301), and monitoring for setting the security mode by the user is performed. A region is selected.

  FIG. 4A is a schematic diagram illustrating an example of a security mode setting screen (monitoring area selection screen) displayed on the operation display unit 221. As illustrated in FIG. 4A, the operation display unit 221 displays buttons for a parent household area, a child household area, and a common area for selecting a monitoring area for setting a security mode. For example, when the user sets the security mode for the common area, when the user presses the button for the common area, the monitoring area for setting the security mode is selected as the common area. Note that the monitoring area where the security mode is set may be further subdivided within the area so that it can be selected in units of rooms.

  In this way, the operation display unit 221 accepts selection of a monitoring area by the user (step S302). Next, the operation display unit 221 displays a security mode setting screen for the selected monitoring area, and a security mode to be set by the user is selected.

  FIG. 4B is a schematic diagram illustrating an example of a common area security mode setting screen (security mode selection screen) in the operation display unit 221. As illustrated in FIG. 4B, the operation display unit 221 displays buttons corresponding to a security state, a home security state, a self-security state, and a security release state as security mode settings. For example, when the security mode is set from the security release state to the security state, when the user presses a button in the security state, the security mode to be set is selected as the security state. In this way, the operation display unit 221 receives the selection of the security mode by the user (step S303).

  Next, the security mode switching unit 221 determines whether the monitoring area selected as the target for setting the security mode is a parent household area, a child household area, or a common area (step S304). If the selected monitoring area is the parent household area (step 304: parent household area), the security mode switching unit 221 sets the security mode of the parent household area to the selected security mode (step S305). . That is, the security mode switching unit 221 stores the selected security mode in the parent household area security mode storage unit 212.

  Similarly, when the selected monitoring area is a child household area (step S304: child household area), the security mode switching unit 221 similarly sets the security mode of the child household area to the selected security mode ( Step S306). That is, the security mode switching unit 221 stores the selected security mode in the child household area security mode storage unit 213.

  Furthermore, when the selected monitoring area is a shared area (step S304: shared area), the security mode switching unit 221 similarly sets the security mode of the shared area to the selected security mode (step S307). . That is, the security mode switching unit 221 stores the selected security mode in the common area security mode storage unit 214. The selected security mode is set in the selected monitoring area by the procedure as described above. Accordingly, the guard mode can be set separately for the parent household area, the child household area, and the common area.

  Next, a security mode setting process using an exit timer by the security device 110 according to the present embodiment will be described. FIG. 5 is a flowchart showing a procedure for setting the security mode using the exit timer by the security device 110 in the parent household area.

  First, when the user of the parent household area switches (sets) the security mode of the parent household area from the operation display unit 221 of the controller 220 when going out, the security mode switching unit 211 is selected by the user. The security mode is stored in the parent household area security mode storage unit 212. Next, the timer setting unit 216 determines whether or not the security mode of the parent household area has been switched to the security state or the self-security state (step S501). The timer setting unit 216 is for starting the exit timer only when the user goes out. If the security mode of the parent household area is not set to either the security state or the self-security state (step S501: No), the timer setting unit 216 waits until it is set.

  On the other hand, when the guard mode of the parent household area is set to either the guard state or the self-guard state (step S501: Yes), the timer setting unit 216 activates the exit timer and is set in advance. Time counting for a certain time is started (step S502). FIG. 6 is a schematic diagram illustrating an example of a timing start screen when the exit timer is activated. As shown in FIG. 6, a message indicating that the exit timer is being used, a monitoring area (parent household area), a remaining timer time until the start of security, and a timer setting release button are displayed.

  Next, the abnormality detection unit 217 measures the sensors 201a to 201n in the parent household area or the sensor 207a in the common area during the time of the exit timer from when the user in the parent household area sets the security mode until the user goes out. When the detection signal is received from ˜207n (step S503), the abnormality notification unit 215 cancels (or ignores) the received detection signal and does not perform notification or notification based on the detection signal (step S504).

  Then, the abnormality reporting unit 215 determines whether or not the exit timer started by the timer setting unit 216 has passed the set fixed time (step S505). When the fixed time set by the timer setting unit 216 has not elapsed (step S505: No), the abnormality reporting unit 215 returns to step S503 and repeats the process until the fixed time has elapsed by the timer setting unit 216.

  On the other hand, when the set fixed time has elapsed (step S505: Yes), the timer setting unit 216 stops the exit timer (step S506). In addition, when the detection signal is received from the abnormality detection unit 217 after the exit timer is stopped, the abnormality notification unit 215 performs notification or notification based on the detection signal according to the set security mode.

  Next, a security mode setting process using an exit timer by the security device 110 according to the present embodiment will be described. FIG. 7 is a flowchart showing a procedure for setting the security mode using the exit timer by the security device 110 in the child household area.

  First, when the user in the child household area switches (sets) the security mode of the child household area from the operation display unit 231 of the sub-controller 230 when going out, the security mode switching unit 211 is selected by the user. The security mode is stored in the security mode storage unit 213 for the child household area. Next, the timer setting unit 216 determines whether or not the security mode of the child household area has been switched to the security state or the self-security state (step S701). The timer setting unit 216 is for starting the exit timer only when the user goes out. If the security mode of the child household area is not set to either the security state or the self-security state (step S701: No), the timer setting unit 216 waits until it is set.

  On the other hand, when the security mode of the child household area is set to either the security state or the self-security state (step S701: Yes), the timer setting unit 216 activates the exit timer and is set in advance. Time counting for a certain time is started (step S702).

  Next, the abnormality detection unit 217 counts the sensors 203a to 203n in the child household area or the sensor 207a in the common area during the time of the exit timer from when the user in the child household area sets the security mode until the user goes out. When the detection signal is received from ˜207n (step S703), the abnormality notification unit 215 cancels (or ignores) the received detection signal, and does not perform notification or notification based on the detection signal (step S704).

  Then, the abnormality reporting unit 215 determines whether or not the exit timer started by the timer setting unit 216 has passed the set fixed time (step S705). When the fixed time set by the timer setting unit 216 has not elapsed (step S705: No), the abnormality reporting unit 215 returns to step S703 and repeats the process until the fixed time has elapsed by the timer setting unit 216.

  On the other hand, when the set fixed time has elapsed (step S705: Yes), the timer setting unit 216 stops the exit timer (step S706). In addition, when the detection signal is received from the abnormality detection unit 217 after the exit timer is stopped, the abnormality notification unit 215 performs notification or notification based on the detection signal according to the set security mode.

  Next, the security mode setting process using the entrance timer by the security device 110 according to the present embodiment will be described. FIGS. 8A and 8B are flowcharts illustrating a procedure for setting the security mode using the entrance timer.

  First, the timer setting unit 216 determines whether or not the security mode of the common area is set to the security state, the self-security state, or the home security state (step S801). That is, the timer setting unit 216 determines whether the security state, the self-security state, or the home security state is stored in the common area security mode storage unit 214 as the current common area security mode.

  When the security mode of the common area is set to the security state, the self-security state, or the home security state (step S801: Yes), the abnormality detection unit 217 has received a detection signal from the sensors 207a to 207n of the common area. (Step S802). When the abnormality detection unit 217 has not received a detection signal from the sensors 207a to 207n in the common area (step S802: No), the process of step S801 is repeated again.

  On the other hand, when the abnormality detection unit 217 receives a detection signal from the sensors 207a to 207n in the common area due to the presence of a person, opening / closing of a door, or the like (step S802: Yes), the timer setting unit 216 starts an entrance timer, Time measurement for a predetermined time set in advance is started (step S803). Next, when the counting of the entrance timer is started, the output unit 218 outputs a timer sound indicating that there is a visitor or a message prompting an operation for switching the security mode to the security release state (step S804). For example, a melody as a timer sound or a message such as “Please release security within a predetermined time” is output.

  Next, the abnormality detection unit 217 detects detection signals from the sensors 207a to 207n in the common area, the sensors 201a to 201n in the guarded parent household area, or the sensors 203a to 203n in the guarded child household area during the entrance timer timing. Is received (step S805), the abnormality reporting unit 215 suspends all received detection signals and prevents notification or notification based on the detection signals (step S806).

Then, the abnormality reporting unit 215 determines whether or not the security mode of the parent household area or the child household area has been switched to the security release state (step S807). That is, the abnormality reporting unit 215 determines whether or not the security release state is stored in the parent household area security mode storage unit 212 or the child household security mode storage unit 213 by the security mode switching unit 211.

  When the security mode of the parent household area or the child household area is switched to the security release state (step S807: Yes), it is determined that the user of the parent household area or the child household area has returned home, and an error is reported. The unit 215 cancels all pending detection signals (step S808). If the security mode of the parent household area and the child household area is set to the security release state, and only the security mode of the common area is being guarded, the security mode of the common area is switched to the security release state. Similarly, the abnormality notifying unit 215 cancels all the detection signals that have been put on hold.

On the other hand, when the security mode of the parent household area or the child household area is not switched to the security release state (step S807: No), the abnormality notification unit 215 has the entrance timer started by the timer setting unit 216 set. It is determined whether or not a certain time has passed (step S809). If the fixed time set by the timer setting unit 216 has not elapsed (step S809: No), the abnormality reporting unit 215 returns to step S804 and continues to step S804 until the fixed time has elapsed by the timer setting unit 216. repeating the processing of ~S807.

  On the other hand, if the predetermined time set by the timer setting unit 216 has elapsed (step S809: Yes), it is determined that the intruder has detected the parent household area, child household area, or common area. When the security mode is set to the security state, the abnormality notification unit 215 notifies the monitoring center that an abnormality has been detected (step S810). Moreover, the abnormality notification unit 215 notifies the parent household area or the child household area that an abnormality has been detected (step S811).

  And when the set fixed time passes, the timer setting part 216 will stop an entrance timer (step S812). Also, when the abnormality reporting unit 215 cancels all the detection signals (step S808), the timer setting unit 216 stops the entrance timer (step S812).

  In step S801, when the security mode of the common area is not set to the security state, the self-security state, or the home security state (step S801: No), the timer unit 218 indicates that the security mode of the parent household area is the security state and the self-security. It is determined whether or not the security mode of the child household area is set to the security release state (step S813). That is, the security mode storage unit 212 for the parent household area stores the security status, the self security status, or the home security status, and determines whether the security release status is stored in the security mode storage unit 213 for the child household area. To do.

  If the security mode of the parent household area is not set to the security status, self-security status, or home security status, and the security mode of the child household area is not set to the security release status (step S813: No), the entrance Exits the process without starting the timer.

  On the other hand, when the security mode of the parent household area is set to the security state, the self-security state, or the home security state, and the security mode of the child household area is set to the security release state (step S813: Yes), the abnormality detection unit 217 determines whether a detection signal is received from the sensors 201a to 201n in the parent household area (step S814). When the abnormality detection unit 217 has not received a detection signal from the sensors 201a to 201n in the parent household area (step S814: No), the process of step S813 is repeated again.

  On the other hand, when the abnormality detection unit 217 receives a detection signal from the sensors 201a to 201n in the parent household area due to the presence of a person, opening / closing of a door, or the like (step S814: Yes), the timer setting unit 216 activates an entrance timer. Then, the timing of a predetermined time set in advance is started (step S815). Next, when the counting of the entrance timer is started, the output unit 218 outputs a timer sound indicating that there is a visitor or a message prompting an operation to switch the security mode to the security release state (step S816). For example, a melody as a timer sound or a message such as “Please release security within a predetermined time” is output.

  Next, the abnormality detection unit 217 receives detection signals from the sensors 201a to 201n in the parent household area during the entrance timer (step S817). When receiving the detection signal from the abnormality detection unit 217, the abnormality notification unit 215 suspends all the received detection signals so as not to perform notification or notification based on the detection signals (step S818).

Then, the abnormality reporting unit 215 determines whether or not the security mode of the parent household area has been switched to the security release state (step S819). That is, the abnormality reporting unit 215 determines whether the security release state is stored in the parent household area security mode storage unit 212 by the security mode switching unit 211.

  When the security mode of the parent household area is switched to the security release state (step S819: Yes), it is determined that the user of the parent household area has come home, and the abnormality reporting unit 215 is suspended. All detection signals are canceled (step S820).

  On the other hand, when the security mode of the parent household area is not switched to the security release state (step S819: No), the abnormality notification unit 215 has passed the set fixed time by the entrance timer started by the timer setting unit 216. It is determined whether or not it has been done (step S821). When the fixed time set by the timer setting unit 216 has not elapsed (step S821: No), the abnormality reporting unit 215 returns to step S816 and continues to step S816 until the fixed time has elapsed by the timer setting unit 216. Repeat the process of ~ S819.

  On the other hand, when the fixed time set by the timer setting unit 216 has elapsed (step S821: Yes), it is determined that the intruder or the like has detected, and the parent household area is set to the guarded state. In this case, the abnormality notifying unit 215 notifies the monitoring center that an abnormality has been detected (step S822). Moreover, the abnormality notification unit 215 notifies the parent household area or the child household area that an abnormality has been detected (step S823).

  And when the set fixed time passes, the timer setting part 216 will stop an entrance timer (step S824). Also, when the abnormality reporting unit 215 cancels all the detection signals (step S820), the timer setting unit 216 stops the entrance timer (step S824).

  In addition, in step S801, when the security mode of the common area is not set to the security state, the self-security state, or the home security state (step S801: No), and when returning to the parent household area, FIG. As described in 2 above, when the security mode of the common area is not set to the security state, the self-security state, or the home security state, returning to the child household area is the same as in FIG. 8-2. Omitted.

  As described above, in the security device 110 according to the first embodiment, it is possible to set the security of the common area independently of the parent household area and the child household area, such as an intruder into the common area, etc. Even if an abnormality is detected, it is reported to the parent household area or child household area that the abnormality has been detected, or the monitoring center is notified that an abnormality has been detected, so it is possible to respond quickly to abnormalities in the common area. can do.

  Furthermore, in the security device 110 according to the first embodiment, even when the user sets the security and then goes out through the common area, the user is mistakenly regarded as an intruder within the set fixed time. In addition, even if the user goes out after setting up security and going home after passing through the common area, within a set time after the abnormality due to the user entering the common area is detected, The user is not mistakenly regarded as an intruder, and an erroneous alarm is not notified, or the fact that an abnormality has been detected is not notified. Therefore, it is possible to reduce the time and labor spent on checking and dealing with misinformation. Further, the user in the parent household area or the child household area can know the existence of other users who go out or return home through the common area and can recognize the situation of the monitoring area. Therefore, even when an abnormality in the monitoring area is detected, a quick response can be made.

(Second Embodiment)

Therefore, if the users in the parent household area and the child household area are responsible for setting up their own area when they go out, both household areas will be in security when users in both household areas go out. The common area is in a guarded state. For this reason, users in the parent household area and the child household area need only perform the operation to switch the security mode for their own area without confirming the status of the other household, and the responsibility is clarified and the operation is forgotten. Can be avoided.

  In addition, the security mode can be set independently for the common area, so that, for example, the parent household area and the child household area are at home while the parent household area and the child household area are at home. If it is set and only the common area is set to the security release state, it is possible to notify a user who is in the common area that someone has entered from the entrance.

  Here, the configurations and functions of the parent household area security mode storage unit 212, the child household area security mode storage unit 213, the common area security mode storage unit 214, and the abnormality detection unit 217 are the same as those in the first embodiment. Since it is the same as that of the form, the description is omitted.

  The abnormality reporting unit 815 is configured when the security mode of the parent household area, the child household area, or the common area is set to report a security state or a self-security state, that is, a security mode storage unit for the parent household area 212, when a security state or a self-security state is stored in the security mode storage unit 213 for the child household area or the security mode storage unit 214 for the common area, the sensors 201a to 201n and the sensors 203a to 203n installed in the area Alternatively, when a detection signal is output from the sensors 207a to 207n, the abnormality detection unit 217 detects this and indicates that an abnormality has been detected in the monitoring center 130 or a mobile phone held by the user when going out. report.

  Moreover, in this Embodiment, the abnormality notification part 815 detects this with the abnormality detection part 217, when the detection signal is output from the sensors 201a-201n of the parent household area or the sensors 203a-203n of the child household area. Notify that an abnormality has been detected from the speaker 823 of the controller 820 in the common area.

The timer setting unit 816 is stored by the security mode switching unit 811 in the current security mode of the parent household area stored in the parent household area security mode storage unit 213 or the child household area security mode storage unit 213. When the current security mode of the child household area is switched to the security state or the self-security state, the time measurement of the exit timer for setting a predetermined timer time is started. During the time of the exit timer, even if an abnormality is detected in the parent household area or the child household area that has been switched to the guarded state or self-guarded state, the detection signal is canceled so that unnecessary notification or notification is not performed. To do.

  For example, assuming that the user in the parent household area goes out with the parent household area set to the guarded state, based on the time it takes for the user to go out after performing the operation to set the guarded state By setting the exit timer time, it is possible to prevent unnecessary notification or notification from being performed. At this time, the user in the parent household area only needs to perform an operation to set the security mode of the parent household area to the security state or the self-security state without worrying about the security mode of the common area.

While the entrance timer is counting, a detection signal based on the abnormality detection is suspended so that unnecessary notification or notification is not performed when a user in the parent household area or the child household area that has returned home is detected. If the security mode of the parent household area or the child household area is switched to the security release state before the predetermined timer time elapses, the suspended detection signal is cancelled, and the guard is activated until the predetermined timer time elapses. If the mode is not switched, a notification that an abnormality has been detected is sent.

For example, assuming that the user in the parent household area returns home from the outside and switches the parent household area to the security release state, the user returns home and enters the parent household area, and then the security status is released in the parent household area. By setting the admission timer time based on the time until switching to, it is possible to prevent unnecessary notification or notification from being performed. At this time, the user in the parent household area only needs to perform an operation for setting the security mode in the parent household area to the security release state without worrying about the security mode in the common area.
