  Exemplary embodiments of a security device, a monitoring system, and a security state switching method according to the present invention will be described below in detail with reference to the accompanying drawings. The present invention is not limited to these embodiments.

(First embodiment)
A first embodiment will be described with reference to the accompanying drawings. First, a configuration example of a monitoring system to which the present invention is applied will be described. FIG. 1 is a block diagram illustrating a configuration of a monitoring system according to the first embodiment. The monitoring system 10 includes a security device 100 and a monitoring center 300, and the security device 100 and the monitoring center 300 are connected via a network 400 such as a telephone line, a wireless network, or the Internet.

  The security device 100 according to the present embodiment includes an electric energy measurement unit 101, a power control unit 102, a detection information acquisition unit 103, an absence determination unit 104, a timer unit 105, a security state switching unit 106, and an operation. A panel 107, an operation panel control unit 108, a transmission / reception unit 109, a power amount database 120, a device database 130, and a security state storage unit 140 are provided. It should be noted that various devices (for example, the lighting device 201 and the air conditioning device 202) and the sensor 205 are included in an area (hereinafter referred to as a security area) in which a security state can be individually set in a house to be guarded or a store / house. Is installed, and power to each device is supplied via a distribution board that distributes power for each security area. In addition, a lighting device 201, an air conditioning device 202, a lighting switch 203, an air conditioning switch 204, a sensor 205, and the like are installed in each of the plurality of security areas.

  The power amount measuring unit 101 measures the amount of power used by devices installed for each security area, for example, the lighting device 201 and the air conditioning device 202 as shown in FIG. Here, the security area is obtained by dividing a security target such as a house into several areas, specifically, living room, dining room, children's room, bedroom, hallway, and the like. The power amount measuring unit 101 is specifically a measuring device that is installed in a distribution board and measures the amount of power for each circuit supplied from the distribution board to each security area.

  The power amount database 120 stores an absence determination power amount that is a power amount for determining whether a person is absent for each security area. FIG. 2 is an explanatory diagram illustrating an example of a data configuration of the electric energy database. As shown in FIG. 2, the power amount database 120 stores a security area ID for identifying a security area and an absence determination power amount in association with each other.

  In addition, the absence determination power amount for each security area is based on the lifestyle of people who normally live in the security area, the type of equipment installed in the security area, and when the person is absent, the equipment is switched off. It depends on whether or not. Therefore, in order to set the absence determination power amount that is more realistic, when there are no guardians in the guard target, the power amount consumed in each guard area is measured for a certain period, and the result is stored in the power amount database 120 You may make it do.

  The absence determination unit 104 compares the power amount used for each guard area measured by the power amount measurement unit 101 with the absence determination power amount for each guard region stored in the power amount database 120 and is used. If the amount of power that is present is equal to or less than the absence determination power amount, it is determined that there is no person in the security area.

  The timer unit 105 measures the time that has elapsed since the absence determination unit 104 determined that no person was present in the security area.

  The security state switching unit 106 switches the security state of each security area to the home security mode or the security release mode according to the operation of the operation panel 107. Further, when the absence determination unit 104 determines that there is no person in the security area, the security state switching unit 106 switches the security state of the security area determined to have no person from the security release mode to the alert mode.

  Here, in the home security mode, when the housekeeper is at home in a part of the security area within the security target and the housekeeper is absent in the other security area, by setting the security area where the family is absent, When an abnormality is detected in the security area, it means a state in which the abnormality is notified to the householder and an alarm is transmitted to the monitoring center. The security release mode refers to a state in which an alarm is not transmitted to the monitoring center even when an abnormality is detected by a sensor or the like in the security area.

  Also, the alert mode refers to a state in which, when an abnormality is detected in the security area, an alarm is not transmitted to the monitoring center, but a warning is given to a householder that an abnormality has been detected. The security mode is a state that is set when all the householders are out and absent, and an alarm is transmitted to the monitoring center when a sensor or the like detects an abnormality.

  The device database 130 stores information on devices to be turned off when the absence determination unit 104 determines that no person is present in the security area among the devices installed in each security area. FIG. 3 is an explanatory diagram showing an example of the data structure of the device database. As illustrated in FIG. 3, the device database 130 stores a security area ID and a device ID that identifies a device in association with each other.

  As an example, a case will be described in which devices with the device IDs “K0001” to “K0005” are installed in the security area indicated by the security area ID “1”. As shown in FIG. 3, “K0001”, “K0004”, and “K0005” are stored in the device ID in association with the security area ID “1”. For example, if the device ID “K0001” is an air conditioner, the device ID “K0004” is a television, and the device ID “K0005” is an electric stove, it is determined that there is no person in the security area ID “1” where these devices are installed. In the case of being turned off, these devices are stored in the device database 130 in order to turn off the power. On the other hand, if the device ID “K0002” is a video deck and the device ID “K0003” is an aquarium air pump containing tropical fish, a problem occurs when the power is turned off even if no one is present. Do not store. As described above, by storing the devices to be turned off in the device database 130, it is possible to reduce useless power without any trouble.

  When the absence determination unit 104 determines that no person is present in the security area, the power control unit 102 performs control so that the power supply of the device corresponding to the security area ID stored in the device database 130 is turned off. Specifically, the power switch is provided with two three-way circuits, and the power control unit 102 controls connection of the three-way circuit to turn the power switch on or off. The use of the three-way circuit is an example, and the present invention is not limited to this.

  The detection information acquisition unit 103 acquires detection information detected by the sensor 205. Here, the detection information is a detection area ID for identifying a security area where the sensor is installed and a detection signal indicating that an abnormality has been detected. Here, the sensor 205 will be briefly described. The sensor 205 detects an abnormality in the security area. For example, the sensor 205 includes an infrared sensor that detects a person based on a change in the amount of received infrared light, a blocking sensor that detects a person by blocking infrared light, a sign sensor that detects a person by disturbance of electromagnetic waves, and a magnet. These are various sensors that detect abnormalities in the security area, such as a magnet sensor that detects opening and closing of the door.

  The operation panel 107 displays or outputs information related to the security device 100 and accepts input of information by the user. Further, the operation panel 107 accepts the setting of the security state for each security area. The operation panel 107 displays the current security state for each security area. When the absence determination unit 104 determines that no person is present in the security area, the operation panel 107 displays or outputs a sound indicating that the alert mode is set in the security area. In addition, when an abnormality is detected by the sensor 205 in the security area set to the alert mode or the home security mode, the operation panel 107 notifies that the abnormality has been detected by voice, text, lighting of an abnormality detection lamp, or the like. To do.

  The operation panel control unit 108 controls the operation panel 107 such as outputting display information to the operation panel 107 and inputting information from the operation panel 107.

  The transmission / reception unit 109 transmits / receives various information to / from the monitoring center 300 connected via the network 400.

  The security status storage unit 140 stores the current security status of the security device 100 for each security area. Specifically, the security state received by the operation panel 107 or the security state switched by the security state switching unit 106 is stored. FIG. 4 is an explanatory diagram illustrating an example of a data configuration of the security state storage unit. As shown in FIG. 4, the guard state storage unit 140 stores the guard area ID and the currently set guard state in association with each other.

  Next, the security state switching process by the security device 100 configured as described above will be described. FIG. 5 is a flowchart showing a security state switching processing procedure performed by the security device.

  First, the absence determination unit 104 acquires the absence determination power amount for each security area from the power amount database 120 (step S501). The power amount measuring unit 101 measures the power usage amount for each security area (step S502). The absence determination unit 104 determines whether the power usage amount is equal to or less than the absence determination power amount for each security area (step S503). When it is determined that the power usage amount is not equal to or less than the absence determination power amount for each security area (step S503: No), that is, when it is determined that there is a person in the security area, the process returns to step S502.

  When it is determined that the power usage amount is less than or equal to the absence determination power amount for each security area (step S503: Yes), that is, when it is determined that no person is present in the security area, the detection information acquisition unit 103 detects the detection information. Whether or not is acquired is determined (step S504). Here, the detection information is a security area ID that identifies the security area where the sensor is installed, and a detection signal indicating that an abnormality has been detected. It can be determined whether or not an abnormality has been detected. If it is determined that the detection information has been acquired (step S504: Yes), that is, if it is determined that a person has been detected in the security area, the process returns to step S502.

  When it is determined that the detection information is not acquired (step S504: No), that is, when it is determined that no person is detected in the security area, the absence determination unit 104 sets the power usage amount to be equal to or less than the absence determination power amount. It is determined whether or not a predetermined time has elapsed since it was determined that it has become (step S505). When it is determined that the predetermined amount of time has not elapsed since it was determined that the power usage amount was equal to or less than the absence determination power amount (step S505: No), the process returns to step S502 to continue timing.

  When it is determined that the predetermined time has elapsed since it was determined that the power consumption amount is equal to or less than the absence determination power amount (step S505: Yes), the power supply control unit 102 obtains a device ID corresponding to the security area from the device database 130. Obtain (step S506). The power control unit 102 performs control so that the switch of the device corresponding to the device ID is turned off (step S507).

  The security state switching unit 106 switches the security state of the security area from the security release mode to the alert mode (step S508). The security state switching unit 106 stores the alert mode as the current security state of the security area in the security state storage unit 140 (step S509). The operation panel control unit 108 controls the operation panel unit 107 to notify that the mode has been switched to the alert mode (step S510).

  In the above-described embodiment, the power usage amount in the security area is equal to or less than the absence determination power amount, the detection information of the sensor installed in the security area is not acquired, and the power usage amount is the absence determination power. When a predetermined time has elapsed since it was determined that the amount was below the amount, the alert mode is stored as the security state of the security area, but instead, the power usage amount of the security area was less than the absence determination power amount When judged, the alert mode may be stored as the security state of the security area.

  In addition, when the power usage amount of the security area is less than the absence determination power amount and the detection information of the sensor installed in the security area is not acquired, the alert mode is stored as the security status of the security area. In addition, when the predetermined amount of time has elapsed since the amount of power used in the security area is less than or equal to the absence judgment power amount, The mode may be stored.

  Note that when the lighting device is turned on while the security state of the security area is set to the alert mode, the alert mode may be switched to the security release mode. In addition, when the security release mode or the home security mode is set from the operation panel 107 while the security state of the security area is set to the alert mode, the mode is changed from the alert mode to the set mode. It may be. Further, whether or not the security state setting can be changed based on the power consumption may be selected for each security area.

  Next, the abnormality detection process by the security device 100 will be described. FIG. 6 is a flowchart illustrating an abnormality detection processing procedure performed by the security device.

  First, the detection information acquisition unit 103 determines whether detection information is acquired (step S601). The detection information is a security area ID and a detection signal of a security area where a sensor that detects an abnormality is installed as in the case described above. This detection signal is a detection signal indicating that a person has been detected. When it is determined that the detection information has not been acquired (step S601: No), the process returns to step S601 and the detection information acquisition is repeated. When it is determined that the detection information has been acquired (step S601: Yes), the detection information acquisition unit 103 acquires the security state corresponding to the security area ID from the security state storage unit 140 (step S602).

  The detection information acquisition unit 103 determines which mode is set as the acquired security state (step S603). If it is determined that the “security release mode” is set in the security state (step S603: security release mode), the process returns to step S601. In this case, even if a person is detected, since it is a householder, alerting and warning transmission are not performed.

  When it is determined that the “warning mode” is set in the security state (step S603: alert mode), the operation panel control unit 108 notifies the operation panel 107 that an abnormality has been detected in the security area. Control is performed (step S604). For example, a sound indicating that an abnormality has been detected in the child's room is output from the speaker of the operation panel 107, or the security area where the abnormality has been detected on the operation panel 107 is flashed and displayed to notify the abnormality.

  When it is determined that the “home security mode” is set in the security state (step S603: home security mode), the operation panel control unit 108 notifies the operation panel 107 that an abnormality has been detected in the security area. Control is performed (step S605), and an alarm is transmitted to the monitoring center 300 (step S606).

  In this way, when the amount of power used in the security area is equal to or less than the absence determination power amount, the alert mode is set for the security status of the security area, so the operation burden of switching the security status when entering and exiting the room Can be reduced. In addition, since unnecessary devices are turned off when no one is present, useless power consumption can be prevented. In addition, the security area where the person is absent does not become unguarded, and security without leakage or omission can be performed.

  In addition, when an abnormality is detected in the security area in which the alert mode is set, a notification is first given to a home person who has detected the abnormality. Thereby, the family member can confirm an abnormality such as an intruder. In addition, when there are a plurality of residents, it can be used as means for grasping where other householders are in the house. In the alert mode, notification to the householder is performed, but notification to the monitoring center is not made, so there is no false information. Further, since the user is set to the alert mode without performing any operation, it is not necessary to perform a complicated operation of setting the security state every time the user enters or leaves the security area (room), thereby improving convenience. be able to.

  In the above-described embodiment, the power usage amount is used to determine whether or not there is a person in the security area. However, instead of the power usage amount, water usage amount, gas usage amount, etc. It may be determined by measuring various energy amounts that change when a person is present in the security area.

(Second Embodiment)
A second embodiment will be described with reference to the accompanying drawings. With respect to the configuration example of the monitoring system to which the present invention is applied, a different part from the first embodiment will be described. The other parts are the same as those in the first embodiment, so the description is omitted with reference to the above description.

Since the function is the same as that of the first embodiment, description thereof is omitted.

  The power-off determination unit 501 determines whether or not a switch of a predetermined device in the security area has been turned off. Here, the predetermined device is a normal lighting device. In offices, factories, and the like, it can be determined whether or not there is a person in the security area by turning on / off the power of the lighting device in the security area. When the power source of the lighting device is turned off, it is determined that people working in the security area have returned home, and the security status of the security area is set to the security mode. In addition, it may replace with an illuminating device and may determine ON / OFF of a power supply with another apparatus.

  The absence determination unit 504 sets the security area in the security area based on the time that has elapsed since the power-off determination unit 501 turned on / off the power of the predetermined device in the security area or the power of the predetermined device in the security area. Determine if a person is absent.

  When the absence determination unit 504 determines that there is no person in the security area, the security state switching unit 506 switches the security state of the security area from the security release mode to the security mode.

  Next, the security state switching process by the security device 500 configured as described above will be described. FIG. 8 is a flowchart showing a security state switching processing procedure performed by the security device.

  First, the power-off determination unit 501 determines whether or not the illumination device 201 is turned off for each security area (step S801). If it is determined that the lighting device 201 for each security area is not turned off (step S801: No), that is, if it is determined that there is a person in the security area, the process returns to step S801.

  When it is determined that the lighting device 201 in the security area is turned off (step S801: Yes), that is, when it is determined that no person is present in the security area, the detection information acquisition unit 103 acquires the detection information. Whether or not (step S802). Here, the detection information is a security area ID for identifying the security area where the sensor is installed, and a detection signal indicating that an abnormality has been detected, and an abnormality is detected in the security area where the power of the lighting device 201 is turned off. It can be determined whether or not it has been detected. If it is determined that the detection information has been acquired (step S802: Yes), that is, if it is determined that a person has been detected in the security area, the process returns to step S801.

  When it is determined that the detection information has not been acquired (step S802: No), that is, when it is determined that no person is detected in the security area, the absence determination unit 504 has turned off the lighting device 201. It is determined whether or not a predetermined time has elapsed since time (step S803). If it is determined that the predetermined time has not elapsed since the power source of the lighting device 201 was turned off (step S803: No), the process returns to step S801 to continue timing.

  If it is determined that a predetermined time has elapsed since the power of the lighting device 201 was turned off (step S803: Yes), the power supply control unit 102 acquires a device ID corresponding to the security area from the device database 130 (step S803).

The security state switching unit 106 switches the security state of the security area from the security release mode to the security mode (step S806). The security state switching unit 506 stores the security mode as the current security state of the security area in the security state storage unit 140 (step S807).

  In the embodiment described above, the lighting device in the security area is turned off, the detection information of the sensor installed in the security area is not acquired, and the lighting device in the security area is turned off. When a predetermined time has passed since the time when it was set, the security mode is stored as the security status of the security area, but instead, the security status of the security area is set as the security status when the lighting device in the security area is turned off. A security mode may be stored.

  Further, when the power of the lighting device in the security area is turned off and the detection information of the sensor installed in the security area is not acquired, the security mode may be stored as the security status of the security area, Alternatively, when a predetermined time has elapsed since the lighting device in the security area is turned off and the lighting device in the security area is turned off, the security mode is stored as the security state of the security area. Also good.

  Next, the abnormality detection process by the security device 500 will be described. FIG. 9 is a flowchart showing an abnormality detection processing procedure performed by the security device.

  First, the detection information acquisition unit 103 determines whether detection information has been acquired (step S901). The detection information is a security area ID and a detection signal of a security area where a sensor that detects an abnormality is installed as in the case described above. If it is determined that the detection information has not been acquired (step S901: No), the process returns to step S901 and the acquisition of the detection information is repeated. When it is determined that the detection information has been acquired (step S901: Yes), the detection information acquisition unit 103 acquires the security state corresponding to the security area ID from the security state storage unit 140 (step S902).

  The detection information acquisition unit 103 determines whether the acquired security mode of the security state is set (step S903). When it is determined that the security mode is not set in the security state (step S903: No), the process ends. In this case, no alarm is transmitted to the monitoring center 400 because the person is a house even if a person is detected. When it is determined that the security mode of the security state is set (step S903: security mode), an alarm is transmitted to the monitoring center 300 (step S904).

  In this way, when the lighting device in the security area is turned off, the security mode is set in the security state of the security area without any operation by the user, so the operation burden on the user can be reduced. In addition, since unnecessary devices are turned off when no one is present, useless power consumption can be prevented. In addition, the security area where the person is absent does not become unguarded, and security without leakage or omission can be performed.

  Next, the case where the security device 500 according to the present embodiment is applied to a building having a plurality of floors as security areas will be described. FIG. 10 is an explanatory diagram showing an example of implementation in a building having a plurality of floors. As shown in FIG. 10, each floor is a security area, and a lighting device 201, an air conditioning device 202, a lighting switch 203, an air conditioning switch 204, and a sensor 205 are installed for each security region. A security device 500 is installed at the entrance, and the lighting switch 203, the air conditioning switch 204, the sensor 205, and the security device 500 are connected by wiring.

  Alternatively, the operation panel 107 and the operation panel control unit 108 for setting the security mode or the security release mode for the security area shown in FIG. 7 may be provided for each floor, and the security state may be switched on each floor.

  In addition, as above-mentioned, a security area | region is good also considering each floor as one security area, and also dividing one floor into several security areas. In addition, air conditioning equipment is listed as an example of equipment that controls the power supply. In addition to air conditioning equipment, there are equipment that should be turned off when there are no people, such as printers, copiers, and electric pots. It may be a target. In this case, the device ID for identifying the device is set as the device to be controlled by using the technology of information home appliances, the wiring is connected to the security device 500, and the device ID is stored in the device database 130. By keeping this, the power supply can be controlled.

  Note that if the device is connected to the network in the building and can be controlled remotely, the power operation may be performed by remote control instead of the circuit.
