Description

  The present invention consumes electric power generated by solar power generation, and sells power to an electric power company when the power generation amount in solar power generation is larger than the power consumption and when the power generation amount in solar power generation is smaller than the power consumption. The present invention relates to an energy equipment operating status display monitor that displays the operating status of energy equipment such as solar power generation equipment and power consuming equipment in a solar power generation system that purchases power from a power company. .

  Conventionally, the current power generation amount and the current power consumption amount in photovoltaic power generation are displayed side by side with numerical values, and if the current power generation amount> the current power consumption amount, an animated image of coins entering the wallet is displayed. Patent Document 1 discloses an energy device operation status display device that displays an animation image in which coins are taken out of a wallet when current power consumption> current power generation amount is displayed.

  However, in the conventional example shown in Patent Document 1 described above, the current power generation amount of photovoltaic power generation and the current power consumption amount are displayed as numerical values, and coins are removed from the wallet by animation. Or the incoming animation display only displays whether the current state is the power sale state or the power purchase state, and represents the total power generation and consumption until the current day of the day. The display does not show at a glance the difference between the total power generation and the total consumption, that is, which of the total power generation and the total consumption up to the present day is larger.

  In other words, even if you know the momentary power generation and consumption at the current time by numerical values or animations, you can't know the power generation status and power consumption status at the same time. Motivation to save energy if the amount of power generated up to the current day is less than the current amount of power consumed on the day or if it is less than expected, It's no good.

  Thus, in the above conventional example, due to the difference between the total power generation amount and the total consumption amount up to the current date of the day, the power generation status and power consumption status up to the current date of the day are not known. Visually knowing the difference between total power generation and total consumption at a glance does not give users any motivation to save energy.

Here, it is conceivable to display the total power generation amount and the total consumption amount up to the present day as numerical values. However, in the numerical display of the total power generation amount ○○ kW and the total consumption amount Δ △ kW, the general person, especially It is difficult to draw attention to children, elderly people, and housewives, and it is difficult to motivate energy saving after the present time, and devices that consume power are used without being aware of energy saving even after the present time.
JP 2002-297229 A

  The present invention was invented in view of the above-mentioned conventional problems, and it is possible to visually and effectively motivate energy saving after the present time to induce energy saving behavior to the user. It is an object of the present invention to provide an energy equipment operation status display monitor capable of displaying such information.

  In order to solve the above-mentioned problems, the energy equipment operation status display monitor according to the present invention consumes the power generated by solar power generation, and sells the power to the power company when the power generation amount of the solar power generation is larger than the power consumption. In addition, an energy device for displaying information on power generation and power consumption on the monitor A in a solar power generation system in which the shortage is purchased from an electric power company when the power generation amount in the photovoltaic power generation is smaller than the power consumption. It is an operation status display monitor, and a power generation information display unit 1 that displays information about power generation and a power consumption information display unit 2 that displays information about power consumption are provided adjacent to the screen displayed on the monitor A, The total power generation from the count start time to the current time, which is the reference for the day, and the total consumption in the adjacent power generation information display 1 and power consumption information display 2 The bar graph display units 3 and 4 are displayed adjacent to each other with bar displays 3a and 4a, respectively, and the total amount of power generation up to the current time on the current day is determined by the difference in display length between the adjacent bar displays 3a and 4a. The difference in total consumption is displayed, and the current power generation value display unit 5 for displaying the power generation amount and consumption at the current time as numerical values on the adjacent power generation information display unit 1 and power consumption information display unit 2 And a current consumption numerical value display section 6 is provided.

  With such a configuration, the power generation information display unit 1 that displays information about power generation and the power consumption information display unit 2 that displays information about consumption are provided adjacent to each other on the screen displayed on the monitor A. Thus, on one screen, not only can information related to power generation and information related to consumption be compared at the same time, but also bar graph display sections 3, 4 provided in the adjacent power generation information display section 1 and power consumption information display section 2 can be viewed. The total power generation from the count start time to the current time and the total consumption are displayed as bar displays 3a and 4a, respectively, because of the difference in display length between adjacent bar displays 3a and 4a. When the difference between the total power generation and the total consumption up to the current time on the current day can be seen at a glance, and the total consumption up to the current time on the current day is higher than expected The difference can be seen visually as the difference in the bar display in the bar graph, and it can be understood that there has been insufficient energy-saving efforts up to the present day. It is possible to strongly induce actions to reduce the power consumption as much as possible. In this case, since the power generation amount and the consumption amount at the current time are further displayed, by checking the difference between the bar displays 3a and 4a in the bar graph while checking the power generation amount and the consumption amount at the current time, It is possible to know the difference between the total power generation and the total consumption until the time, and more accurately know the relationship between power generation and consumption.

  In addition, the bar display 3a that displays the total amount of power generated up to the current time of the day is divided into the consumed amount 7 of the electricity generated up to the current time of the day and the sold power amount 8 sold. In addition, in the bar display 4a that displays the total consumption up to the current time of the day, the consumption 7 that consumed the generated electricity out of the electricity consumed up to the current time of the day, and the purchase amount 9 of the purchased electricity 9 Display of the difference between the total power generation amount and the total consumption amount up to the current time of the current day represented by the difference in display length between the adjacent bar displays 3a and 4a. It is preferably displayed as the difference between the amount of electricity sold out of the generated electricity and the amount of electricity purchased out of the electricity consumed up to the current time.

  With this configuration, knowing the difference between the total power generation and total consumption up to the current time of the day, at the same time, the amount of electricity sold up to the current time and the electricity consumed up to the current time It is possible to know the difference in the amount of electricity purchased, thereby providing a stronger motivation for energy saving.

  Moreover, it is preferable to display the total power generation amount on the current day up to the current time on the power generation information display unit 1 as a numerical value and to display the total consumption amount on the current day up to the current time on the power consumption information display unit 2 as a numerical value.

  By adopting such a configuration, the power generation information display unit 1 displays the total power generation amount and the total consumption amount for the current day up to the current time as the adjacent bar displays 3a and 4a as described above, and also displays numerical values. By displaying, stronger motivation for energy saving can be given by the bar displays 3a, 4a and numerical values.

  Further, the power generation information display unit 1 is provided with a power generation display icon 10 and the power consumption information display unit 2 is provided with a consumption display icon 11. When the current time is a power sale time, the power generation display icon 10 is larger than the consumption display icon 11. When the power generation amount and the consumption amount at the present time are balanced, the power generation display icon 10 and the consumption display icon 11 are displayed with the same size, and when the current time is the time of power purchase, the consumption display is displayed. It is preferable to control so that the icon 11 is displayed larger than the power generation display icon 10.

  With such a configuration, depending on the size of the display of the consumption display icon 11 and the power generation display icon 10, whether the relationship between the power generation amount and the consumption amount at the current time is power sales, equilibrium, or power purchase is at a glance. For example, when the consumption display icon 11 is displayed in the same size as the power generation display icon 10 or when the consumption display icon 11 is the power generation display icon 10, it is in a balanced state or a power purchase state. It can provide a strong energy-saving motivation to curb power use.

  As described above, according to the present invention, the difference between the total power generation amount and the total consumption amount up to the current time on the current day can be visually recognized at a glance due to the difference between the lengths of the adjacent bars. Therefore, there is an advantage that it is possible to provide a display that can give a strong motivation for the user and cause the user to induce an energy saving action.

  The monitor A is provided with a monitor control unit 18 that performs arithmetic processing on the transmitted data and displays the power generation and power consumption status (that is, the operating status of the energy equipment on the power generation side and the consumption side) on the monitor A as a screen. It is supposed to be.

  As a screen displayed on the monitor A, in the present invention, there is a power generation / consumption screen B1 showing at least power generation and power consumption status as shown in FIG.

  The power generation / consumption screen B1 is adjacent to a power generation information display unit 1 for displaying information related to power generation and a power consumption information display unit 2 for displaying information related to consumption so as to occupy most of the entire screen at the center. It is provided. In the embodiment shown in FIG. 1, the power generation information display unit 1 and the power consumption information display unit 2 are arranged adjacent to each other on the left and right, and the power generation information display unit 1 and the power consumption information display unit 2 are displayed on the screen. The area is the same or substantially the same size. In the embodiment shown in the accompanying drawings, an electric water heater operating state display unit 21 indicating an operating state of an electric water heater which is one of the energy devices on the consumption side is provided at one end portion in the left-right direction of the power generation / consumption screen B1. ing. The power generation information display unit 1 and the power consumption information display unit 2 are both wider than the electric water heater operating state display unit 21 so that the display on the power generation information display unit 1 and the power consumption information display unit 2 is conspicuous. is there.

  In addition, an upper bar-shaped display unit 22 and a lower bar-shaped display unit 23 each having a narrow vertical width are provided along the upper end and lower end of the power generation / consumption screen B1.

  The adjacent power generation information display unit 1 and power consumption information display unit 2 are bar graphs that display the total power generation amount and the total consumption amount from the count start time to the current time, which are the basis of the current day, as bar displays 3a and 4a, respectively. Display units 3 and 4 are provided. In the embodiment shown in the attached drawings, the entire region of the power generation information display unit 1 is a bar graph display unit 3, and the entire region of the power consumption information display unit 2 is a bar graph display unit 3. Of course, if each bar graph display part 3 and 4 is comprised so that it may adjoin right and left via the boundary of the electric power generation information display part 1 and the power consumption information display part 2, each bar graph display part 3 and 4 will each be The power generation information display unit 1 and the power consumption information display unit 2 may be formed in part.

  The bar graph display units 3 and 4 are lower ends of the power generation information display unit 1 and the power consumption information display unit 2, that is, the boundary between the power generation information display unit 1, the power consumption information display unit 2 and the lower bar display unit 23. Is the reference line that becomes zero, and the total power generation and the total consumption from the count start time (in the embodiment, 0:00 am as the count start time) to the current time, which are the reference of the day, The displays 3a and 4a are displayed, and the display is configured such that the bar graph displays 3a and 4a extend from the bottom to the top with the bar graph display portions 3 and 4 facing upward. As described above, the total power generation amount and the total consumption amount are displayed on the bar graph display units 3 and 4 adjacent to each other by the bar displays 3a and 4a so that they are displayed as a bar graph. In this bar graph, if there is a difference between the total power generation from the count start time that is the reference of the day to the current time, and the total consumption, the difference is between the upper end of the bar display 3a and the upper end of the bar display 4a. It will be expressed as a difference.

  In the bar display 3a displayed on the bar graph display unit 3, the consumed amount 7 of the electricity generated up to the current time of the day and the sold power amount 8 of the electricity generated up to the current time of the day are sold. In addition, the bar display 4a displayed in the bar graph display unit 4 displays a consumption amount 7 of the electricity consumed up to the current time of the day. And the amount of electricity purchased until the current time of the day is divided into 9 and displayed. Of the electricity consumed up to the current time of the day, the consumed amount 7 of the generated electricity is displayed on the lower side of the double bar displays 3a and 4a, and the upper side of the bar display 3a (that is, the power generation up to the current time of the day). The amount of electricity sold 8 is displayed on the upper side of the display of the consumed consumption 7 of the generated electricity, and the display of the consumed amount 7 of the electricity generated up to the current time of the day is displayed on the upper side of the bar display 4a. A power purchase amount 9 is displayed on the upper side.

  As described above, (the length of the bar display 3a displayed on the bar graph display unit 3) = (the length corresponding to the consumed amount 7 of the electricity generated up to the current time of the day on the bar display 3a) ) + (The length corresponding to the amount of power sold 8 of the electricity generated up to the current time of the day in the bar display 3a), and (the bar display 4a displayed on the bar graph display unit 4) Length) = (the length corresponding to the consumed amount 7 of electricity generated up to the current time of the day on the bar display 4a) + (buy out of electricity consumed up to the current time of the day on the bar display 4a) It is displayed as a length corresponding to the amount of purchased electricity 9).

  Accordingly, as described above, the difference between the adjacent bar display 3a and the bar display 4a is recognized as the difference between the total power generation amount and the total consumption amount from the count start time serving as the reference of the day to the current time, At the same time, it is also recognized as the difference between the amount of power sold and the amount of power purchased from the count start time that is the reference of the day to the current time.

  In this way, just by looking at the difference between the adjacent bar displays 3a and 4a, the difference between the total power generation amount and the total consumption amount up to the current time of the day and the difference between the power sale amount and the power purchase amount can be seen at a glance. Strongly motivated for energy conservation, such as when the difference between total power generation and consumption, or the difference between the amount of electricity sold and the amount of electricity purchased is different than expected. Will be given to users.

  By the way, the bar displays 3a and 4a displayed on the bar graph display units 3 and 4 respectively extend from the bottom to the top as the total power generation amount and the total consumption increase, but the bar displays 3a and 4a are bar graph display units. 3 and 4 can be displayed only up to the upper end of the power generation information display unit 1 and the power consumption information display unit 2, so that the total power generation amount or the total consumption amount increases and the upper end of the bar graph display unit 3 or the bar graph display unit When the upper end of 4 reaches the upper end of the bar graph display unit 3 or the bar graph display unit 4, the bar graph display unit 3 and the bar display 3a displayed on the bar graph display unit 4 are displayed so as to reduce the display ratio. It is like that. For example, if the upper end of the power generation information display unit 1 and the upper end of the power consumption information display unit 2 at the top of the bar graph display units 3 and 4 are initially set to display 10 kW, respectively, the total power generation amount or the total consumption If any of the quantities reaches 10 kW first, the upper end of the bar graph display units 3 and 4, the upper end of the power consumption information display unit 2, and the upper end of the power consumption information display unit 2, for example, will display 20 kW. The bar display 3a, 4a displayed on the screen is reduced in height to 1/2, and thereafter the bar graph at the reduced rate as the total power generation amount and the total consumption amount increase. The display parts 3 and 4 will extend upward.

  A current power generation numerical value display unit 5 is further provided on the upper part of the power generation information display unit 1 to display the power generation amount and consumption at the current time as numerical values.

Therefore, the current power generation value display unit 5 and the current consumption amount adjacent to each other on the left and right. By looking at the numerical values displayed on the numerical display 6, it is possible to know the amount of power generation and consumption at the current time, and at the same time, by comparing the left and right, it is possible to immediately understand whether there is more power generation or consumption at the current time. It has become.

  In addition, a power generation display icon 10 for representing a power generation state at the current time is provided in a substantially central part of the adjacent power generation information display unit 1 and a power consumption state at the current time is represented in a substantially central part of the power consumption information display unit 2. The consumption display icon 11 is provided. The power generation display icon 10 and the consumption display icon 11 display the power generation display icon 10 larger than the consumption display icon 11 when the state of power generation and consumption at the present time (current time) is the power sale time, and the power generation at the current time When the amount and consumption are in balance, the power generation display icon 10 and the consumption display icon 11 are displayed in the same size, and when the current time is power purchase, the consumption display icon 11 is displayed from the power generation display icon 10. The display is also controlled so as to display a larger image. As a result, it can be immediately visually determined whether the amount of power generation or consumption at the current time is large (that is, whether the power is being sold, purchased, or balanced). Looking at the icon 11, the power generation amount and the consumption amount at the current time displayed on the power generation display icon 10 and the consumption display icon 11 in the upward current power generation value display unit 5 and the current consumption value display unit 6. By looking at the numerical values, you can understand at a glance the state of power generation and consumption at the current time, and this also gives users a strong motivation for energy saving.

  A ball line-shaped electric flow display unit 30 in which a large number of balls are arranged across the lower portions of the power generation information display unit 1 and the power consumption information display unit 2 is provided. The ball line-shaped electric flow display unit 30 is a power generation display icon 10. Is connected to the consumption display icon 11, and the ball-shaped electric flow display unit 30 displays the display of each ball in a certain color (for example, green) and sequentially displays the color display toward the left side at the time of power sale. On the other hand, at the time of power purchase, each ball is displayed with a certain color (for example, blue) and the color display is sequentially colored toward the left side. You can see at a glance whether you are currently selling or buying electricity.

  Further, the power generation information display unit 1 is further provided with a total power generation value display unit 24 for displaying the total power generation amount of the current day up to the current time as a numerical value. A total consumption numerical value display unit 25 for displaying the total consumption of the day as a numerical value is provided, and the difference between the total power generation amount and the total consumption amount is visually recognized by the difference between the adjacent bar displays 3a and 4a. At the same time, it is possible to know the total power generation amount and the total consumption amount by the numerical values displayed on the adjacent total power generation value display unit 24 and the total consumption value display unit 25, and to further save energy through the screen of the monitor A. The motivational effect can be demonstrated.

  Note that one end of the power generation / consumption screen B1 in the left-right direction has one of the energy devices on the consumption side on the electric water heater operation state display unit 21 indicating the operation state of the electric water heater that is one of the energy devices on the consumption side. The operation status of an electric water heater (for example, an electric water heater using a heat pump) is displayed, and the hot water supply amount of the day is displayed as a bar graph and numerical values, and the current hot water supply state is displayed. The icon 31 is displayed so that the hot water supply state display icon 31 moves during hot water supply, and the hot water supply state display icon 31 stops when stopped.

  The upper bar-shaped display unit 22 provided at the upper end of the power generation / consumption screen B1 is currently displaying an operation state display unit 32 for displaying the operation state of solar power generation (that is, whether the power generation is in progress or stopped). A current screen display unit 33 for displaying the screen with icons, a 24-hour clock display unit 34, and a calendar / time numerical value display unit 42 are provided.

  The 24-hour clock display unit 34 has a band shape, and one end (the left end in the figure) of the band in the longitudinal direction becomes a start time display unit 34a (for example, a portion representing midnight), and the other end in the longitudinal direction terminates. It is a time display portion 34b (for example, a portion representing 12:00 pm).

  The band-shaped 24-hour clock display unit 34 displays the current time at a position corresponding to the current time of the 24-hour clock display unit 34 while changing the display position from the start time display unit 34a side to the end time display unit 34b side. The current time display mark 35 is provided. In the embodiment shown in the accompanying drawings, the current time display mark 35 is displayed as a vertical line. That is, the current time display mark 35 displayed as a vertical line functions as a clock hand of the banded 24-hour clock display unit 34, and the current time can be known by looking at the position of the hand. ing.

  The band-like 24-hour clock display unit 34 is divided into a plurality of divided time zone display units 36a, 36b, and 36c divided into a plurality of time zones having different preset power charges. The band display portions 36a, 36b, and 36c have different display colors (in addition, when the display colors of the plurality of divided time zone display portions 36a, 36b, and 36c are different, the hue, brightness, and saturation are different. Any one element or a plurality of elements).

  Therefore, by knowing the position of the current time display mark 35 in the 24-hour clock display unit 34, it is possible to know at a glance where the current time is located in the plurality of divided time zone display units 36a, 36b, 36c. In addition, it is possible to know how much time is left until the time period when the current electricity rate is changed to the next time zone where the electricity rate is different.

  Here, when the current time is displayed on the divided time zone display part (for example, 36a) with the current time display mark 35, the preset fixed time for switching to the display of the next divided time zone display part (for example, 36b). When it becomes before (for example, 30 minutes before), the display by the current time display mark 35 is controlled to be different (for example, blinking display or different color display). As a result, it is strongly impressed by users that the electricity charge will change in minutes or hours later, and if the electricity charge will increase slightly, the use of energy equipment on the consumer side will be completed. (For example, if you use a vacuum cleaner, a washing machine, an air conditioner, etc. quickly) or if the power charge is getting cheaper, use the energy equipment on the consumer side. A motivation (strong motivation for energy saving) for giving the user an action such as waiting for a certain amount of time (for example, a little waiting for the use of a vacuum cleaner, a washing machine, an air conditioner, etc.) is given.

  On the power generation / consumption screen B1, when the current time display mark 35 displays the current time at a position where one divided time zone display portion (eg 36a) is present, the next divided time zone display portion (eg 36b) is displayed. ) When the preset time (for example, 30 minutes) before the time of switching to the display of “” is displayed, the charge will increase in 30 minutes after the power generation / consumption screen B1, or “the charge will be cheap in 30 minutes after” As shown in the figure, a time zone change notice display unit 37 is provided for displaying, in text and numerical values, how much time later will be switched from the current fee time zone to a different fee time zone. In this case, every time a predetermined time (for example, 3 minutes) elapses, the remaining time until the time zone is changed is “the charge increases in 30 minutes”, “the charge increases in 27 minutes "Mass", "Fee will be higher in 24 minutes" ... and so on.

  In this case as well, as described above, a strong motivation for energy saving can be given to the user.

  Of course, by displaying both the change of the display of the current time display mark 35 and the notice display of letters and numbers in the time zone change notice display section 37, the user is given a stronger motivation for energy saving. Can do.

  The lower bar-shaped display unit 23 provided at the lower end of the power generation / consumption screen B1 is provided with a switching operation unit 38 for switching to different basic screens at the right end and the left end, respectively. Here, the switching operation unit 38 at the right end is a normal circulation basic screen changing unit 38a, and the switching operation unit 38 at the right end of the left end is a reverse circulation basic screen changing unit 38b. Further, the lower bar-shaped display unit 23 switches a part of the display on the power generation / consumption screen B1 or pops up to overlap the power generation / consumption screen B1 while leaving the power generation / consumption screen B1 on the screen. A switching unit 40 for displaying a screen and a detailed screen switching operation unit 41 for switching to a detailed screen for displaying the details displayed on the power generation / consumption screen B1 in more detail are provided.

  The switching unit 40 is, for example, a button that displays “Price display”. When the button that displays “Price display” is touched, the total power generation value display unit 24 of the power generation / consumption screen B1, as shown in FIG. The total amount of electricity generated up to the current day and the amount of electricity corresponding to the total amount of consumption are displayed in a location corresponding to the total consumption amount display unit 25, respectively. In the screen shown in FIG. 2, the button labeled “Price display” in FIG. 1 is switched to the display “Power amount display”. Therefore, when the button “Display power amount” is pressed in FIG. 1 is displayed on the power generation / consumption screen B1.

  FIG. 4 is a block diagram showing the relationship between a plurality of different screens displayed on the monitor A as screens.

  The screen shown on the monitor A is roughly divided into a basic screen B and a detailed screen C.

  On the monitor A, three or more basic screens B1, B2,... Bn including the above-described power generation / consumption screen B1 showing the power generation and power consumption status can be switched and displayed as the basic screen B. Here, when the power generation / consumption screen B1 is the basic screen B1, the basic screen B2,... Bn are also provided with the normal circulation basic screen change means 38a and the reverse circulation basic screen change means 38b as in the power generation / consumption screen B1. It is.
