JP 2013-050278 A

When a power outage occurs, it may not be possible to electrically operate electrically powered devices, which may reduce the security functions of the building. While some buildings are equipped with power storage devices, it may be difficult to operate electrically powered devices when users are out, and there is room for improvement in improving the security functions of buildings during power outages.

The present disclosure aims to provide a control device , a control system, and a control method that improve the security functions of a building during a power outage.

One aspect of the present disclosure is a control device that includes a control unit that controls one or more electrically powered devices installed in a building that has an electricity storage device, and a storage unit that registers information about electrically powered devices that need to be operated in the event of a power outage, and the control unit operates the electrically powered devices registered in the storage unit in the event of a power outage.

1 is a schematic configuration diagram of a control system according to an embodiment of the present invention. FIG. 2 is a schematic configuration diagram of a control device according to the present embodiment. FIG. 2 is a flow diagram of a control system according to the present embodiment.

The control system 1 according to this embodiment controls one or more electrically powered devices 200 installed in a user's building 100. When a power outage occurs in the building 100, the control system 1 controls the electrically powered devices 200 that need to be controlled in the event of a power outage. The building 100 may be a residence such as an apartment building or a detached house, a hospital, a facility, or the like. In this embodiment, an example will be described in which the building 100 is a user's residence.

For example, the building 100 is equipped with multiple electric devices 200. The multiple electric devices 200 include, as electric devices related to the security functions of the building 100, at least one of an opening/closing device that opens and closes fixtures installed at openings in the building 100, and an electronic lock 200-1 that electrically locks and unlocks the fixtures. For example, the fixtures are windows, front doors, or shutters. The opening/closing device is, for example, at least one of an electric shutter 200-2 and an electric unit for high windows 200-3. The electric shutter 200-2 electrically opens and closes shutter curtains. The electric unit for high windows 200-3 electrically opens and closes windows installed at high locations in the building 100.

The control system 1 is installed in a building 100. The control system 1 includes, for example, a distribution board 10, a power storage device 20, a control device 30, a router 40, and a server device 50.

The distribution board 10 supplies power supplied from the electric wires on the utility pole to loads such as the power storage device 20 and multiple electrically powered devices 200. The distribution board 10 supplies power supplied from the electric wires on the utility pole to loads such as the power storage device 20 and multiple electrically powered devices 200. The distribution board 10 may include a power meter and a breaker. The breaker may include, for example, a main breaker and one or more branch breakers. For example, the distribution board 10 may have a power meter and a branch breaker installed on each power line for supplying power to each load.

The power storage device 20 is capable of charging and discharging power. The power storage device 20 converts the power supplied from the distribution board 10 into DC power. The power storage device 20 charges the converted DC power. The power storage device 20 includes a storage battery 21 that can charge DC power. The storage battery 21 is, for example, a lithium-ion battery. The charging and discharging of the power storage device 20 is controlled by the control device 30. The power storage device 20 is equipped with a measurement sensor that measures the remaining amount of power stored in the storage battery 21. The power storage device 20 transmits power storage information, which is the measurement result of the measurement sensor, to the control device 30. The remaining amount of power may be, for example, the terminal voltage of the storage battery 21 or the SOC (State of Charge) of the storage battery 21.

The power stored in the storage device 20 can be supplied to each of the multiple electrically powered devices 200 via the distribution board 10. For example, the power stored in the storage device 20 may be supplied via the distribution board 10 only to electrically powered devices 200 related to the security functions of the building 100.

As shown in FIG. 2, the control device 30 includes a storage unit 31 and a control unit 32. Each component of the control device 30 is implemented by, for example, a hardware processor, such as a CPU (Central Processing Unit), executing a program (software). Some or all of these components may be implemented by hardware (including circuitry), such as an LSI (Large Scale Integrated circuit), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or GPU (Graphics Processing Unit), or may be implemented by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device with a non-transitory storage medium), such as an HDD (Hard Disk Drive) or flash memory, or may be stored in a removable storage medium (a non-transitory storage medium), such as a DVD or CD-ROM, and installed in the storage device by inserting the storage medium into a drive device. The storage device may be composed of, for example, a HDD, flash memory, EEPROM (Electrically Erasable Programmable Read Only Memory), ROM (Read Only Memory), or RAM (Random Access Memory).

Storage unit 31 stores information about electrically-powered devices 200 that need to be operated during a power outage. Electrically-powered devices 200 that need to be operated during a power outage are, for example, electrically-powered devices related to the security functions of building 100. For example, storage unit 31 stores information about at least one of electronic lock 200-1, electric shutter 200-2, and high window electric unit 200-3. Electrically-powered devices 200 that need to be operated during a power outage and are registered in storage unit 31 may be referred to as registered devices.

The control unit 32 controls the operation of the registered devices. For example, the control unit 32 is connected by wire or wirelessly to each of the electronic lock 200-1, the electric shutter 200-2, and the electric unit for high windows 200-3. In the event of a power outage, the control unit 32 operates the electric devices 200 registered as registered devices in the storage unit 31 using the remaining power stored in the power storage device 20.

For example, the control unit 32 determines whether a power outage has occurred. For example, the control unit 32 determines whether a power outage has occurred by determining whether charging of the power storage device 20 is possible. If the control unit 32 determines that a power outage has occurred, it operates the electric device 200 that is registered as a registered device in the storage unit 31. As an example, if the control unit 32 determines that a power outage has occurred, it locks the electronic lock 200-1, controls the electric shutter 200-2 to a closed state, and operates the high window electric unit 200-3 to control the electric window to a closed state.

When the control unit 32 determines that a power outage has occurred, it may determine based on the power storage information whether the remaining amount of stored power in the power storage device 20 exceeds a set value. The set value is, for example, the amount of stored power that can operate a registered device. When the remaining amount of stored power exceeds the set value, the control unit 32 may operate a registered device registered in the storage unit. For example, when the remaining amount of stored power exceeds the set value, the control unit 32 may lock the electronic lock 200-1, control the electric shutter 200-2 to a closed state, and operate the high window electric unit 200-3 to control the electric window to a closed state. For example, the control unit 32 may be a gateway.

The router 40 is connected to the server device 50 via an internet line NW. The router 40 is connected to the control device 30 wirelessly or via a wired connection (e.g., a wired LAN). The router 40 relays information between the server device 50 and the control device 30.

The server device 50 may be located on the internet or in the cloud. The server device 50 is connected to the router 40 via the internet line NW. The server device 50 sends and receives various information to and from the control device 30 via the internet line NW. The server device 50 can communicate via wired or wireless connection with a communication terminal 300 used by a user, such as a mobile phone, smartphone, tablet terminal, or laptop computer.

The flow of the control system 1 will be explained using Figure 3. The control device 30 determines whether or not the power storage device 20 is present in the building 100 (step S101). The control device 30 can communicate with the power storage device 20 using a communication standard such as ECHONET Lite (registered trademark), and may use this communication to determine whether or not the power storage device 20 is present.

If the power storage device 20 is not present in the building 100, the control device 30 terminates the processing shown in FIG. 3. If the power storage device 20 is present in the building 100, the storage unit 31 can register an electric device 200 that controls the state from the first state to the second state during a power outage. For example, a user uses the communication terminal 300 to register the electronic lock 200-1, the electric shutter 200-2, and the high window electric unit 200-3 to the control device 30. The first state is when the electronic lock 200-1 is unlocked, the electric shutter 200-2 is open, or the high window is open. The second state is when the electronic lock 200-1 is locked, the electric shutter 200-2 is closed, or the high window is closed.

The control device 30 registers the electrically powered device 200 transmitted from the communication terminal 300 in the storage unit 31 as an electrically powered device that needs to be operated in the event of a power outage (step S102). The control device 30 determines whether the power storage device 20 can be charged with power from a commercial power source (step S103). If the control device 30 determines that the power storage device 20 can be charged with power from a commercial power source, it determines that a power outage has not occurred and executes step S103 again. If the control device 30 determines that the power storage device 20 cannot be charged with power from a commercial power source, it determines that a power outage has occurred (step S104).

For example, if the remaining amount of electricity stored in the power storage device 20 has not changed or has decreased despite the start of charging the power storage device 20, the control device 30 determines that the power storage device 20 cannot be charged. For example, if the remaining amount of electricity stored in the power storage device 20 has increased as a result of the start of charging the power storage device 20, the control device 30 determines that the power storage device 20 can be charged.

When the control device 30 determines that a power outage has occurred, it determines whether the remaining amount of stored power in the power storage device 20 exceeds a set value based on the power storage information (step S105). When the control device 30 determines that the remaining amount of stored power in the power storage device 20 exceeds the set value, it controls the registered device, which is a device that has been registered in advance in the storage unit 31, using the remaining amount of stored power in the power storage device 20 (step S106).

For example, if the control device 30 determines that the remaining charge in the power storage device 20 exceeds a set value, it controls the electronic lock 200-1 from an unlocked state to a locked state, controls the electric shutter 200-2 from an open state to a closed state, and controls the high window electric unit 200-3 to control the high window from an open state to a closed state. The control device 30 does not need to operate on a registered device that is already controlled to the second state.

The control device 30 includes a storage unit 31 and a control unit 32. The storage unit 31 stores information about electrically powered devices 200 that need to be operated during a power outage. The control unit 32 controls one or more electrically powered devices 200 installed in the building 100 that has the power storage device 20. In the event of a power outage, the control unit 32 operates the electrically powered devices 200 registered in the storage unit 31. This improves the security functions of the building 100 during a power outage.

Although some electrically operated devices can be operated manually, for example, if an electric window is installed at a high location or if the user is not accustomed to manually operating electrically operated devices, it may be difficult to operate them manually during a power outage. Therefore, if shutters cannot be closed or electric locks cannot be locked, the security functions of the building 100 may not be maintained.

In the event of a power outage, the control device 30 operates the electric device 200 registered in the storage unit 31. This allows the electric device to be operated in the event of a power outage even if the electric window is installed at a high location or if the user is not accustomed to manually operating the electric device.

In some cases, buildings are equipped with power storage devices as a countermeasure against power outages. However, if a power outage occurs while a user is out, it can be difficult to operate electrically powered devices. Even if a power storage device is installed inside the building, the security functions of the building 100 may not be maintained. In the event of a power outage, the control device 30 operates the electrically powered devices 200 registered in the storage unit 31, so that the electrically powered devices can be operated even if a power outage occurs while the user is out.

If the electrically-powered devices 200 registered in the storage unit 31 include an opening/closing device for opening and closing an opening, the control device 30 may control the opening/closing device to a closed state if the remaining power storage level exceeds a set value. If the electrically-powered devices 200 registered in the storage unit 31 include an electronic lock, the control device 30 may lock the electronic lock if the remaining power storage level exceeds a set value.

When the power storage device 20 is installed in the building 100 and a power outage is anticipated, the control device 30 may automatically determine the occurrence of a power outage and automatically control the pre-registered electrically powered devices 200 to a safe state, i.e., the second state, by utilizing the remaining power stored in the power storage device 20.

The above describes in detail an embodiment of this disclosure with reference to the drawings, but the specific configuration is not limited to this embodiment and includes designs that do not deviate from the gist of this disclosure.

The control device 30 may transmit information about the remaining amount of power stored in the power storage device 20 to the server device 50 via the router 40. The user may be able to obtain information about the remaining amount of power stored in the power storage device 20 via the communication terminal 300.
