Here, if it is determined that the battery is being discharged (YES in S11), the process proceeds to S12, and if it is determined that the battery is not being discharged (NO in S11), the process proceeds to S13.

In S12, the display screen generation unit 624 determines the background color of the state display screen to be a predetermined background color according to the state of being discharged. More specifically, the display screen generation unit 624 determines the background color of the screen to be the same green as the lighting color of the energy state presentation unit 59 during discharging. In this way, regardless of whether the power is sold or purchased, the background color is determined according to the discharge if the power is being discharged. That is, when the display screen generation unit 624 is in the power selling state or the power buying state and is in the discharging state, the background color of the status display screen is set to the display color in the discharging state.

In S13, the energy state determination unit 623 uses the data indicating whether or not the power is being sold, which is acquired by the data acquisition unit 521 from the control device 50 and stored in the storage unit 51, to determine whether or not the power is being sold. Is determined. Here, if it is determined that the power is being sold (YES in S13), the process proceeds to S4, and if it is determined that the power is not being sold (NO in S13), the process proceeds to S5.

In S14, the display screen generation unit 624 determines the background color of the status display screen to be a predetermined background color according to the state in which power is being sold. More specifically, the display screen generation unit 624 determines the background color of the state display screen to be the same blue as the lighting color of the energy state presentation unit 59 at the time of selling power.

In S15, the display screen generation unit 624 determines the background color of the status display screen to be a predetermined background color according to the state in which power is being purchased. More specifically, the display screen generation unit 624 determines the background color of the state display screen to be orange, which is the same as the lighting color of the energy state presentation unit 59 during power purchase.

Although not shown, after the background color is determined in S12, S14, or S15, the display screen generation unit 624 generates a state display screen of the determined background color and displays it on the terminal device T1. Details of the status display screen will be described later with reference to FIGS. 5 to 11.

It is also possible to check the energy state in the power generation system 100 via the server S1. In this case, the terminal device T1 accesses the server S1. Then, the server S1 performs the same processing as in FIG. 4 using various power information acquired from the external cooperation device 60, specifically, data indicating the state of the storage battery 20 and data indicating whether or not the power is being sold. Determine the background color. After that, the server S1 generates a state display screen of the determined background color and displays it on the terminal device T1.

[Processing flow (control device 50)]
The lighting color of the energy state presenting unit 59 of the control device 50 is also determined by the same flow as described above. In the control device 50, the data acquisition unit 521 acquires the power information indicating the state of the storage battery 20 and stores it in the storage unit 51, and the energy state determination unit 523 determines whether or not the battery is being discharged using this power information. do.

If it is determined that the battery is being discharged, the presentation control unit 524 lights the energy state presentation unit 59 with a lighting color corresponding to the discharge. Specifically, it lights up in green. In this way, regardless of whether the power is sold or purchased, if the power is being discharged, the light is turned on in a lighting color corresponding to the power being discharged. That is, when the presentation control unit 524 is in the power selling state or the power buying state and is in the discharging state, the energy state presenting unit 59 is set to the lighting color in the discharging state.

On the other hand, when the energy state determination unit 523 determines that the battery is not being discharged, the energy state determination unit 523 uses the data acquired by the data acquisition unit 521 and stored in the storage unit 51 to indicate whether or not the power is being sold. It is determined whether or not the power is being sold.

Then, when it is determined that the power is being sold, the presentation control unit 524 turns on the energy state presentation unit 59 in blue, which is the lighting color corresponding to the power being sold. On the other hand, when it is determined that the power is not being sold, that is, the power is being purchased, the presentation control unit 524 lights the energy state presentation unit 59 in orange, which is the lighting color corresponding to the power being purchased.

[Example of status display screen (when selling power)]
The details of the status display screen will be described with reference to FIG. FIG. 5 is a diagram showing an example of a state display screen at the time of selling power. (A) of the figure shows the lighting state of the energy state presentation unit 59 at the time of selling power, and (b) (c) of the figure shows an example of the state display screen at the time of selling power.

As shown in FIGS. 5A to 5C, the lighting color of the energy state presenting unit 59 and the background color of the state display screen are the same. This configuration has the advantage that the user can easily grasp the energy state at a glance and easily remember which color corresponds to which energy state. The lighting color and the background color may be any color corresponding to the state of "selling power", and may be, for example, blue.

The state display screen in the present embodiment is composed of two screens, a home screen shown in FIG. 5B and a power flow screen shown in FIG. 5C. The home screen and the power flow screen can be switched by user operation. For example, the power flow screen may be displayed by swiping to the right on the home screen, and the home screen may be displayed by swiping to the left on the power flow screen.

More specifically, the home screen shown in FIG. 5B includes a notification button A1, a menu button A2, a power consumption button A3, and a connection destination switching button A4. It should be noted that each of these buttons is not a physical button, but a display object that can be selected by a selection operation such as tapping or clicking. Further, on this home screen, a numerical value C1 indicating the current generated power in the power generation system 100 is displayed.

The notification button A1 is a button for displaying a notification regarding the operating state of the power conditioner 30 and the power generation system 100. The menu button A2 is a button for displaying the menu screen. The menu screen will be described later based on FIG. The power consumption button A3 is a button for displaying a device-specific power consumption screen showing the power consumption of the load device registered in advance. The device-specific power consumption screen may be any screen as long as the user can view the power consumption of each load device, and may be the same screen as the individual power monitor described later based on FIG. 15, for example. The connection destination switching button A4 is a button for switching the connection destination for displaying the status display screen, and the connection destination switching button A4 displays information indicating the current connection destination. Details of the connection destination switching button A4 will be described later with reference to FIG.

The object B1 appears from the lower end of the home screen, moves upward as shown by the broken line arrow A in the figure, and fades out at the upper end (predetermined position) of the home screen. The appearance and fade-out of object B1 will be described later based on FIG.

On the other hand, the power flow screen shown in FIG. 5C includes a system icon A5, a solar cell icon A6, a storage battery icon A7, and a house icon A8. The fact that two storage battery icons A7 are displayed indicates that the power generation system 100 includes two storage batteries 20. In addition, numerical values related to these icons are displayed in association with each other. Specifically, the system icon A5 is the numerical value C2 indicating the power sold, the solar cell icon A6 is the numerical value C1 indicating the generated power, the storage battery icon A7 is the numerical value C3 indicating the charge / discharge power of the storage battery 20, and the house icon A8. Is displayed in association with the numerical value C4 indicating the power consumption. The arrangement of each icon is not particularly limited, but it is preferable not to arrange any other icon on the straight line connecting the solar cell icon A6 and any other icon. This is because, as will be described later, the space between the solar cell icon A6 and the other icons is a display area for moving and displaying the object B1.

Then, the object B1 is displayed between the icons. The object B1 shows the flow of electric power and the magnitude of electric power between the devices corresponding to each icon, and moves in the direction shown by the broken line arrows B to D in FIG. 5 (c). Specifically, since the power is being sold in this example, the solar cell module 10 is generating power.

[Modification example]
In the above embodiment, photovoltaic power generation is exemplified as an example of power generation using natural energy, but the present invention can be applied to power generation other than photovoltaic power generation. For example, the present invention can be applied to a power generation system that performs wind power generation or geothermal power generation.

In the above embodiment, an example of matching the lighting color of the energy state presentation unit 59 with the background color of the state display screen has been shown, but these colors may be any corresponding colors and may not necessarily be the same color. The corresponding color is a color that the user can recognize that the lighting color and the background color have a corresponding relationship. For example, a display color similar to the lighting color is also a corresponding display color.

In the above embodiment, an example of matching the lighting color of the energy state presentation unit 59 with the color of the entire background of the state display screen is shown, but the lighting color and the color of a part of the state display screen correspond to each other. All you need is. That is, the "background color" refers to the color of all or part of the status display screen. For example, the lighting color and the color of the upper region of the status display screen may correspond to each other.

In the above embodiment, an example in which a plurality of circular objects B1 show the flow of electric power or the like has been described, but the object showing the flow of electric power or the like may be a single object, and the shape thereof is not limited to the circular shape.

In the above embodiment, an example is shown in which the lighting color of the energy state presentation unit 59 of the control device 50 and the background color of the state display screen are matched. However, the background color of the status display screen may correspond to the lighting color of the lighting unit that the device related to the power generation system lights to indicate the status of the power generation system, and the lighting unit provided in the device other than the control device 50. It may correspond to the lighting color of. For example, when the external cooperation device 60 includes a lighting unit, the lighting color may correspond to the background color of the status display screen.

In the above embodiment, an example in which the power generation system 100 is controlled by the control device 50 and the external cooperation device 60 is shown, but the device configuration for controlling the power generation system 100 is not limited to this example. For example, the power generation system 100 may be controlled by one device including the control device 50 and the external cooperation device 60. Further, for example, some functions of the external cooperation device 60 (for example, a function of displaying a status display screen) may be performed by a device separate from the external cooperation device 60.

Further, the display destination of the status display screen is not limited to the terminal device T1, and for example, a monitor device provided with a display unit may be added to the components of the power generation system 100, and the status display screen may be displayed on the monitor device. .. However, as described in the above embodiment, the power generation system 100 is preferably configured to include the control device 50 and the external cooperation device 60, and the status display screen is preferably displayed on the user's terminal device T1. When the above monitor device is used, it is necessary to connect the monitor device to the distribution board 40, the power conditioner 30, and the router R1 by wiring, the installation work is complicated, and the installation location of each device is limited. Is. For example, based on the above wiring connection restrictions, the monitoring device is arranged at an intermediate point between the installation position of the distribution board 40, the installation position of the router R1, and the place where the user can easily view the status display screen. .. Further, when using the above-mentioned monitor device, the user needs to go to the place where the monitor device is installed to check the status display screen.

On the other hand, in the configuration of the above embodiment, the control device 50 is in the vicinity of the distribution board 40, the external cooperation device 60 is in the vicinity of the router R1, the terminal device T1 is in the vicinity of the user, and so on. It can be placed near the connection point with the outside. This facilitates the installation work of the power generation system 100 and enables the user to easily check the status display screen on the terminal device T1 on hand.

Further, the configuration of the above embodiment is a distributed system including a control device 50, an external cooperation device 60, and a terminal device T1. By adopting such a distributed system, it is possible to maintain the power generation function, which is the most important function in the power generation system 100, even if some of the devices constituting the system stop functioning due to a failure or the like. Become. For example, when the external cooperation device 60 stops functioning, the power generation history data cannot be transmitted from the control device 50 or the output control schedule data cannot be acquired, and the function is degraded, but the power generation can be continued. Further, when the terminal device T1 stops functioning, the history of power generation and consumption and the detailed operating state cannot be confirmed, but the power generation can be continued.

The presentation of the state in the control device 50 is a presentation by lighting (may be blinking or the like) of the lighting unit, and is compared with the conventional presentation of the state by displaying an image on the monitor device. It is a simple one. However, since the power generation system 100 is usually operated normally, it is sufficient for the user to confirm the state of power buying and selling and the state of discharge of the storage battery 20, and the state is presented by the control device 50. A simple presentation is sufficient.

Further, when the user wants to confirm the detailed state, the user may display the state display screen on the terminal device T1. At this time, even if the terminal device T1 is a general-purpose terminal such as a smartphone, the background color of the status display screen is a color corresponding to the lighting color indicating the status of the control device 50. It can be reminiscent of 50 or the power generation system 100. That is, according to the configuration of the above embodiment, it is possible to make the user recognize that the functions are decentralized as if they were an integrated device without making the user aware of it. Then, it is possible to eliminate the complexity and annoyance of the prior art.

[Example of implementation by software]
The control blocks (particularly, the control unit 52 and the control unit 62) of the control device 50 and the external cooperation device 60 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or by software. It may be realized.

In the latter case, the control device 50 and the external cooperation device 60 include a computer that executes instructions of a program that is software that realizes each function. This computer includes, for example, at least one processor (control device) and at least one computer-readable recording medium in which the program is stored. Then, in the computer, the processor reads the program from the recording medium and executes the program, thereby achieving the object of the present invention. As the processor, for example, a CPU (Central Processing Unit) can be used. As the recording medium, a "non-temporary tangible medium", for example, a ROM (Read Only Memory) or the like, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. Further, a RAM (Random Access Memory) for expanding the above program may be further provided. Further, the program may be supplied to the computer via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. It should be noted that one aspect of the present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the above program is embodied by electronic transmission.

〔summary〕
The information processing device (external cooperation device 60, server S1) according to the first aspect of the present invention is an information processing device that causes a terminal device (T1) to display a state display screen showing the state of a power generation system (100) using natural energy. The background color of the status display screen is the lighting color of the lighting unit (energy state presentation unit 59) that is lit by a predetermined device (control device 50) related to the power generation system to indicate the state of the power generation system. It is configured to have the corresponding display color.

According to the above configuration, since the lighting color of the lighting unit and the background color of the status display screen are the corresponding colors, it is easy for the user to recognize what color the status of the power generation system is represented by. Therefore, the user who confirms the state of the power generation system by using the terminal device can more easily recognize the state. The corresponding display color is a color that the user can recognize that the display color and the lighting color have a corresponding relationship. For example, a display color having the same color as or a similar color to the lighting color is a corresponding display color.

In a conventional general photovoltaic power generation system, a single monitor device has realized control of a power conditioner, communication with the outside, display of a status, and the like. For this reason, in the conventional general photovoltaic power generation system, it is not necessary to perform cooperation and synchronization between the constituent devices in the first place. On the other hand, one aspect of the present invention employs a configuration in which a status display screen is displayed on a terminal device which is a device different from a predetermined device related to the power generation system.
