Furthermore, the control system 10 may include a notification unit 15 that notifies that a predetermined device is being controlled in a weather warning mode.

The control system 10 is constructed with a computer having one or more devices including, for example, a processor (CPU), memory, input/output ports, and the like. That is, control system 10 may consist of one or more devices. Also, the control system 10 may be constructed of one or a plurality of servers, a part of which is connected via a network such as the Internet. The facility 1 may be installed with an energy management system that monitors the power consumption of the entire facility and controls each facility, equipment, etc. of the facility 1, and the control system 10 may be configured as part of the energy management system.

The control system 10 preferably has an operation terminal 40 for inputting various setting information. The operation terminal 40 may be a dedicated terminal for the control system 10, or may also be used as an operation terminal for the energy management system or the like. In the example shown in FIG. 1, the operation terminal 40 is installed inside the facility 1, but the operation terminal 40 may be configured by a mobile terminal such as a notebook computer, tablet terminal, or smart phone.

In this embodiment, the acquisition unit 11, the output unit 12, etc. are configured by the home server 17, and are configured by devices different from the operation terminal 40, but the operation terminal 40 may be provided with the functions of the acquisition unit 11, the output unit 12, etc., and the operation terminal and the home server may be integrated.

The operation terminal 40 is a terminal device having a display section 41 and an operation section 42 . A suitable display unit 41 is a display such as a liquid crystal display or an organic EL display. The display unit 41 displays, for example, weather information including a predetermined weather warning acquired by the acquisition unit 11, a screen for requesting user approval, a screen for accepting various settings, and the like. Examples of the operation unit 42 include buttons, a numeric keypad, a keyboard, and the like, and a touch panel integrated with the display unit 41 may be used. Menu buttons and the like, which will be described later, constitute an operation unit 42 .

3 and 4 are diagrams showing examples of home screens displayed on the display unit 41. FIG. The home screen is a screen that is displayed when the control system 10 is activated, during standby, or the like. As illustrated in FIGS. 3 and 4, the home screen may display information such as the power generation status of the power generation equipment, the power usage status in the facility 1, the state of charge (SOC) of the power storage device 32, and the current time. Also, at the bottom of the home screen, for example, menu buttons for inputting various setting information and switching screens are displayed.

In the examples shown in FIGS. 3 and 4, an operation button for switching between the two screens is displayed at the bottom left of the screen. The screen illustrated in FIG. 3 also displays the amount of hot water of the water heater 28 . On the other hand, the screen illustrated in FIG. 4 displays operation buttons for displaying the power consumption for each circuit branched by the distribution board 20 .

Weather information acquired by the acquisition unit 11 may be displayed on the home screen. Further, on the home screen, it may be notified (displayed) that a predetermined device is being controlled by the weather warning mode. The notification is performed by the function of the notification unit 15 . The home screen may display whether or not a weather warning has been issued, the type of weather warning that has been issued, whether or not the device is being controlled in response to the issuance of the weather warning, and the type and operation of the device to be controlled, for example, such as "weather warning is being issued (●● warning)" and "storage battery is being charged". Note that these pieces of information may be displayed on a screen other than the home screen.

FIG. 5 is a diagram showing an example of a notification screen in weather warning mode. The notification unit 15 may cause the display unit 41 of the operation terminal 40 to display that the weather warning has been issued when a predetermined weather warning that triggers the output of the control command by the output unit 12 is issued and the information thereof is acquired by the acquisition unit 11. In the example shown in FIG. 5, the notification screen is displayed as a popup on the home screen, but it is preferable that the notification screen be displayed as a popup even when other screens are displayed. The notification unit 15 may also display the type of issued weather warning, the area where the weather warning was issued, and the like. Also, information such as a weather warning or advisory that does not trigger the output of the control command may be displayed.

6A to 8B in addition to FIGS. 1 and 2, the acquisition unit 11, the output unit 12, the first reception unit 13, and the second reception unit 14 will be described in further detail.

The acquisition unit 11 acquires weather information transmitted from the server 50 via, for example, the Internet line or a dedicated line. Alternatively, the acquisition unit 11 may access the server 50 at a predetermined frequency to acquire weather information. The weather information acquired by the acquisition unit 11 may include not only information related to a predetermined weather warning that triggers the output of a control command by the output unit 12, but also information such as warnings. Moreover, the weather information acquired by the acquisition unit 11 includes, for example, cancellation information as well as issuance information such as a predetermined weather warning. The acquisition unit 11 preferably causes the storage unit 16 to store the acquired weather information.

The output unit 12 outputs a control command to a predetermined device to control the operation of the predetermined device when the acquisition unit 11 acquires information related to issuing a predetermined weather warning. As a specific example, when a predetermined weather warning such as heavy rain, flood, storm, or heavy snow is issued, a control command (hereinafter sometimes referred to as "charging command") for starting charging or increasing the amount of charge to the power storage device 32 is output. The output unit 12 may also output a control command for increasing the amount of hot water to the water heater 28 (hereinafter sometimes referred to as "increase command"). Alternatively, the power generation amount of the fuel cell device may be increased, and the power storage device 32 may be charged with the generated power. The output of the control commands such as the charge command and the increase command by the output unit 12 may be automatically executed in conjunction with the acquisition of information by the acquisition unit 11 .

There may be multiple controlled devices and controlled operations in the weather warning mode. The output unit 12 may output a control command that instructs the same controlled device to perform different operations when different weather warnings are issued. The control command may be changed between the normal warning and the special warning, and the equipment to be controlled may be changed. For example, when a normal warning is issued, a charge command to set the SOC of the power storage device 32 to 60% or more may be output, and when a special warning is issued, a charge command to set the SOC of the power storage device 32 to 80% or more may be output. Further, when the special warning is issued, the charging control of the power storage device 32 may be executed regardless of the user's setting, and the shutter may be closed regardless of the user's setting. Alternatively, when a special warning is issued, charging control may be executed regardless of the user's setting, and opening/closing of the shutter may be executed based on the user's setting.

In the weather warning mode, there may be a combination of predetermined weather warnings that trigger the output of the control command by the output unit 12 . In this case, the output unit 12 outputs a control command to a predetermined device when the acquisition unit 11 acquires the information regarding the issuance of a plurality of predetermined weather warnings forming the combination. For example, the control command is output from the output unit 12 on condition that the acquisition unit 11 acquires information on both the ●● alarm and the ▲▲ alarm. Further, in the weather warning mode, when a plurality of predetermined weather warnings that trigger the output of the control command are selected, the control command may be output when information regarding issuance of any one of the selected weather warnings is acquired.

The output unit 12 may be configured to output a control command to a predetermined device on the condition that an approval signal is received from the operation terminal 40 when the acquisition unit 11 acquires information regarding the issuance of a predetermined weather warning. In this case, the control of the device in the weather warning mode is executed when the user approves. The output unit 12 outputs, for example, an approval screen for requesting user approval on the display unit 41 of the operation terminal 40, and outputs a control command to a predetermined device when an approval signal based on the user's approval operation is received.

6A and 6B are diagrams showing an example of a weather warning mode approval screen. In the example shown in FIG. 6A, the approval screen is popped up on the home screen, but it is preferable that the approval screen is also popped up when other screens are displayed (the same applies to the release screen described later). The approval screen displays the type of weather warning issued, the area where the weather warning was issued, the equipment and operation to be controlled, information requesting user approval, operation buttons for user approval operation, etc. It should be noted that when a weather warning is issued, the user may be able to select which of the notification screen as shown in FIG. 5, the approval screen as shown in FIGS. 6A and 6B, and the cancellation screen described below to be displayed in setting the weather warning mode.

On the approval screen exemplified in FIG. 6A, a notice requesting user approval regarding charging of the power storage device 32, stating, "A weather warning has been issued. May I start charging the storage battery in preparation for a power outage?" In addition, a notification requesting approval for the operation of the water heater 28 may be displayed, and an example of such a notification is "A weather warning has been issued. May I increase the amount of hot water in the water heater in preparation for a power outage?"

In the approval screen illustrated in FIG. 6B, a plurality of devices to be controlled are displayed, and the current state of each device to be controlled and the operation scheduled to be executed after approval are displayed for each device. When a plurality of devices to be controlled are set, a separate approval screen may be displayed for each device, but user convenience is improved by enabling approval of control execution for multiple devices on a single screen (the same applies to the release screen described later). On the approval screen illustrated in FIG. 6B, a display for requesting approval of charging of power storage device 32 and closing operation of the shutter is output. Specifically, selection portions for "charge" and "do nothing" are displayed for the power storage device 32, and selection portions for "close" and "do nothing" are displayed for the shutter. When the approval screen is displayed, for example, "charge" and "close" are selected, and pressing the decision button will execute these operations. On the other hand, selecting "do nothing" will abort these actions.

The output unit 12 may terminate the control of the predetermined device on condition that the release signal is received from the operation terminal 40 during the control of the predetermined device in the weather warning mode. That is, the output unit 12 may be configured to automatically output a control command to start controlling a predetermined device, and then allow the user to cancel control of the device. The output unit 12 outputs, for example, to the display unit 41 of the operation terminal 40, a release screen that allows the user to release device control, and terminates control of the predetermined device when receiving a release signal based on the user's release operation.

7A and 7B are diagrams showing examples of screens for canceling the weather warning mode. As exemplified in FIGS. 7A and 7B, the release screen displays the type of issued weather warning, the area where the weather warning was issued, the device and operation to be controlled, information for confirming the user's intention, an operation button for the user to perform a release operation, and the like. On the release screen illustrated in FIG. 7A , a notification for confirming the user's intention regarding the charging of the power storage device 32 is displayed along with an operation button, such as "Since a weather warning was issued, charging of the storage battery has started. Do you want to stop charging the storage battery?" As for the operation of the water heater 28, a notification such as "The operation of the water heater has started because a weather warning was issued. Do you want to stop the operation of the water heater?"

In the release screen illustrated in FIG. 7B, a plurality of devices to be controlled are displayed, and the current state of each device to be controlled and the operation scheduled to be executed are displayed for each device. On the release screen illustrated in FIG. 7B, a display for confirming the continuation of charging of power storage device 32 and the continuation of the closed state of the shutter, or the intention to release is output. Specifically, selection portions for "continue charging" and "stop charging" are displayed for the power storage device 32, and selection portions for "remain closed" and "open" are displayed for the shutter. When the release screen is displayed, for example, "Continue charging" and "Keep closed" are selected, and pressing the decision button continues these operations and states. On the other hand, by selecting "stop charging", the charging of the charging device 32 can be stopped, and by selecting "open", the shutter can be opened.

The output unit 12 terminates control of the predetermined device when the predetermined weather warning is cancelled. Specifically, when the acquisition unit 11 acquires the information regarding the cancellation of the predetermined weather warning, the output unit 12 terminates the control of the predetermined device in the weather warning mode. The output unit 12 outputs a control command (stop command) for stopping the device, for example, and terminates the control of the device. Note that the output unit 12 may end the control of the device in response to a cancellation signal from the operation terminal 40 even before the weather warning is canceled. The output unit 12 may cause the display unit 41 to display a screen such as the approval screen or the cancellation screen when the predetermined weather warning is canceled, and after confirming the user's intention, that is, when an approval signal based on the user's approval operation is received, control of the device may be terminated.

On the other hand, the output unit 12 may continue to control the device until the predetermined device enters a predetermined state or until a predetermined period of time elapses when the predetermined weather warning is cancelled. Specifically, when the obtaining unit 11 obtains the information regarding the cancellation of the predetermined weather warning, the output unit 12 determines whether to continue or end the control based on the state of the device to be controlled or the period since the start of the control. When the weather warning is canceled in a short time after the start of the control of the equipment, it may not be preferable to end the control of the equipment immediately from the viewpoint of energy saving.

If the device controlled by the weather warning mode is the power storage device 32, charging of the power storage device 32 may be continued until the SOC of the power storage device 32 reaches a predetermined value (e.g., 80%, etc.) after the predetermined weather warning is cancelled. Further, when the controlled object is the water heater 28, the operation of the water heater 28 may be continued until the amount of hot water of the water heater 28 reaches a predetermined amount (for example, 200 L) after the predetermined weather warning is cancelled.

It should be noted that the control of the predetermined device in the weather warning mode may be stopped by information from other than the output unit 12 . That is, the control system 10 may stop controlling the predetermined device in the weather warning mode even when the stop command is not output from the output unit 12 . As a specific example, when the communication state between the output unit 12 and the device to be controlled is interrupted, the control of the device can be stopped.

As described above, the predetermined weather warning that triggers the output of the control command by the output unit 12 may be set in the system in advance, or may be automatically set by the learning function of the system, but it is preferable to allow the user to manually set it. Also, it may be possible for the user to manually set whether to enable or disable the weather warning mode.

The first receiving unit 13 receives setting information of a predetermined weather warning (hereinafter sometimes referred to as “trigger warning”) that triggers the output of the control command, and sets the trigger warning selected by the user in the control system 10 . The first reception unit 13 causes the display unit 41 of the operation terminal 40, for example, to display a setting screen that allows the user to select a trigger alarm, and stores the information input by the user on this setting screen as a trigger alarm in the storage unit 16.

The second reception unit 14 receives setting information for enabling or disabling the weather warning mode, and sets the information in the control system 10 . The second reception unit 14 causes, for example, the display unit 41 of the operation terminal 40 to display a setting screen that allows the user to select whether to enable or disable the weather warning mode, and the information input by the user on this setting screen is stored in the storage unit 16. The output unit 12 controls predetermined devices when the weather warning mode is active. When there are a plurality of trigger warnings and/or control target devices, the second reception unit 14 may select enabling or disabling of the weather warning mode for each trigger warning or control target device.

The equipment to be controlled in the weather warning mode, the operation to be controlled, etc. may be set in the system in advance, may be automatically set by the learning function of the system, or may be set manually by the user. The control system 10 may include a reception unit that receives setting information such as a controlled device and a controlled operation, and sets the information in the system. Note that the reception (setting) of the information may be performed by the function of the first reception unit 13 or the second reception unit 14 . Also, the setting of various information based on the user's input operation may be performed by one receiving unit.

8A and 8B are diagrams showing examples of setting screens for the weather warning mode. In the example shown in FIGS. 8A and 8B , a screen for receiving setting information for a predetermined weather warning that triggers the output of a control command and a screen for receiving setting information for enabling or disabling the weather warning mode are displayed on one screen, but these may be displayed on separate screens. The display of such a setting screen is performed by the functions of the first reception unit 13 and the second reception unit 14 .

In the setting screen illustrated in FIG. 8A , two selection units for selecting enable/disable of the weather warning mode are displayed in the “weather warning interlocking” item, and a plurality of selection units for selecting the trigger warning in the “alert selection” item are displayed. Multiple trigger alarms can be selected. Also, on this setting screen, the power storage device 32 and the shutter are displayed as devices to be controlled, and the control operation can be selected for each device. In the example shown in FIG. 8A , the power storage device 32 has selection sections for “charge automatically”, “charge after confirmation”, and “do nothing”. When automatic charging is selected, the notification screen or the cancellation screen may be displayed on the display unit 41 . On the other hand, if charging is selected after confirmation, the approval screen may be displayed on the display unit 41 .

On the setting screen illustrated in FIG. 8A , for example, whether or not to notify information about the weather warning mode to a mobile terminal such as a smartphone installed with application software related to the control system 10 can be set as “notification to application”. The setting screen displays two selection sections for selecting whether or not to make the notification. The content of the notification may be, for example, warning issuance information, control information for equipment executed in conjunction with the issuance of the alarm, or both.

On the setting screen illustrated in FIG. 8B, a plurality of weather warning modes can be set, enabling/disabling setting of the weather warning mode for each weather warning, setting of equipment to be controlled, and setting of operation to be controlled are possible. Additionally, a combination of trigger alerts can be set.

The control system 10 implements the functions of the acquisition unit 11, the output unit 12, the first reception unit 13, the second reception unit 14, and the notification unit 15 by reading and executing a control program stored in the storage unit 16, for example. The control program is a program that causes a computer to implement a control method as exemplified in the flow charts described later.

FIG. 9 is a flow chart showing an example of a control procedure in the weather warning mode. In the example shown in FIG. 9, when the weather warning mode corresponding to the issued weather warning is valid, the control of the predetermined equipment is automatically started, but the user's approval may be required to start the control. In this case, for example, between steps S11 and S12 in FIG. 9, a process for requesting user's approval is executed. Specifically, an approval screen is output to the display unit 41 of the operation terminal 40, and device control is started on condition that an approval signal based on the user's approval operation is received. This procedure is executed by the function of the output unit 12 .

As exemplified in FIG. 9, in the weather warning mode, first, information regarding issuance of a predetermined weather warning is acquired (S10). Then, when the weather warning mode corresponding to the weather warning acquired in S10 is valid (S11), a control command is output to a predetermined device to start controlling the device (S12). Alternatively, the procedures of S10 and S11 may be reversed, and only information relating to weather warnings corresponding to valid weather warning modes may be obtained. S10 is executed by the function of the acquisition unit 11, and S11 and S12 are executed by the function of the output unit 12. FIG. On the other hand, if the acquisition unit 11 does not acquire information related to the issuance of a weather warning, or if the weather warning mode is invalid, device control in that mode is not executed.

When the device to be controlled in the weather warning mode is the power storage device 32, for example, a charging command for starting charging or increasing the charging amount is output as the control command in S12. Further, when the device to be controlled is the water heater 28, an increase command for increasing the amount of hot water is output as the control command in S12, for example. Thus, the output unit 12 outputs different control commands depending on the device to be controlled. Further, when different issued weather warnings are issued, different control commands may be output to the same controlled device.

In the example shown in FIG. 9, after control of a predetermined device is started in S12, a release screen is displayed on the display unit 41 of the operation terminal 40 (S13). Then, when a release signal based on an operation on the release screen is received (S14), control of the device is ended (stopped) (S17). S<b>13 , S<b>14 , and S<b>17 are executed by the function of the output unit 12 . On the other hand, if the release signal is not received in S14, or if the approval signal is received in S14, control of the device is continued. According to the series of processes of S12 to S14 and S17, the user can stop the control of the equipment after automatically starting the control of the equipment in the weather warning mode.

In the example shown in FIG. 9, when the information regarding cancellation of the predetermined weather warning corresponding to the weather warning mode being executed is acquired (S15), the control of the device is terminated (S17) through step S16. In S16, it is determined whether the device to be controlled is in a predetermined state or whether a predetermined period of time has elapsed since the start of control, and control of the device ends when this condition is satisfied. For example, if the device to be controlled is the power storage device 32, the SOC may be determined in S16, and if the device to be controlled is the water heater 28, the amount of hot water may be determined in S16. It is also possible to terminate the control of the corresponding device immediately when the information regarding cancellation of the weather warning is obtained.

As described above, according to the control system 10, when a predetermined weather warning is issued, it is possible to make appropriate preparations in preparation for the occurrence of a power failure or the like. Under weather conditions where a weather warning is issued, there is a high possibility that a power failure or the like will occur, but for example, when a weather warning is issued, by increasing the SOC of the power storage device 32, it is possible to use sufficient electricity even during a power failure. Also, by increasing the amount of hot water supplied by the water heater 28 when a weather warning is issued, sufficient hot water can be secured even during a power failure.
