JP 2010-157261 A

  However, the conventional means for displaying the energy saving effect as disclosed in Patent Document 1 is to display the predicted value and the actual measured value for each time on a bar graph or a table. The information displayed in this way is an effective means when there is an administrator who has specialized knowledge, for example, but a user who does not have specialized knowledge in a store, a building, etc. In order to grasp the contents, it was not always easy to grasp visually.

  The present invention has been made in view of such a problem, and provides an energy consumption display device and the like capable of visually and easily displaying predicted values and actual measured values of energy usage. With the goal.

  In order to achieve the above-described object, the first invention is an energy consumption display device, which is based on the energy consumption information in the storage unit and a storage unit that stores energy consumption information for each past predetermined time. Energy consumption prediction means for predicting energy consumption per predetermined time, energy consumption acquisition means for acquiring energy consumption results per predetermined time, and predicted values and results of energy consumption per predetermined time A display unit for displaying a value, and the display unit includes an analog clock display unit, an energy consumption predicted value display unit concentrically provided on a clock panel of the analog clock display unit, and energy consumption An actual measured value display unit, and the predicted energy consumption value display unit displays a predicted value of energy consumption per hour within a set predetermined time range. The actual energy consumption measurement value display unit can display the actual measurement value of energy consumption per hour within a set predetermined time range by color, and the operation of the short hand of the analog clock display unit Accordingly, the energy consumption actual value display unit displays the actual energy consumption actual value every predetermined time.

  By doing so, the predicted value and the actual value of the energy consumption amount are displayed in color for the set time range on the analog clock, so that it is easy to grasp even from a distance. In particular, since the actual value is displayed on the analog clock only for the business hours of stores, for example, the relationship between the business hours and the energy consumption performance is easy to understand, and it is possible to grasp the energy saving effect as if looking at the clock. .

  In the present invention, it is desirable that the display unit can display in real time an energy consumption conversion amount calculated based on an energy consumption amount from the start of calculation to the present time.

  In this case, when the energy consumption conversion amount exceeds a predetermined amount, it is desirable to change the background color of the display unit and display a warning. In addition, it is desirable that the change of the background color of the display unit and the warning display are not performed during the predetermined mask time from the start of the calculation even if the energy consumption conversion amount exceeds the predetermined amount.

  By doing in this way, the user can grasp | ascertain not only the past performance but the energy consumption conversion amount based on the present actual energy consumption (in the predetermined time range). In addition, when the energy consumption conversion amount exceeds a target value or the like, the user can surely grasp the information by changing the background color of the entire screen and displaying a warning.

  The energy consumption conversion amount is calculated, for example, every 30 minutes. That is, for 30 minutes after starting the calculation at a certain time, the converted amount per hour extrapolated 30 minutes after the start of the calculation is displayed based on the energy consumption from the start of the calculation to the present. Therefore, the energy consumption conversion amount may fluctuate greatly at the beginning of the calculation. For this, for example, a mask time such as the first 5 minutes is set, and the mask time is set so that warning display and background color change are not performed even if the energy consumption conversion amount exceeds the target value or the like. It is possible to prevent a warning screen or the like from being displayed due to an instantaneous change in energy consumption.

However, it is needless to say that the present invention can be applied to other energy such as gas or a combination of electricity and gas.

  FIG. 2 is a diagram showing a process for displaying the results of the daily power consumption in a store or a building by the energy consumption display device 1. First, the control unit 3 predicts the power consumption amount in the set time range on the current day from the past power consumption amount information stored in advance in the storage unit 5 (step 101). The power consumption information is information related to the power consumption for each target and every predetermined time (in this embodiment, every 30 minutes) in a plurality of past days for the target store or building. In addition, when there is no past information, you may use the information of the other store or office which takes a similar business form or power consumption.

  For example, the storage unit 5 stores an average value of power consumption for each predetermined time for each past season and each day of the week (for example, weekday, Saturday, Sunday, holiday). The power consumption for every predetermined time on the day is predicted from the power consumption information for the day of the calculation and the past power consumption information for the same season and day of the week. At this time, the power consumption may be corrected from the correlation between the temperature or weather stored in advance and the power consumption based on the weather and temperature information on the day.

  Note that the set time range is set based on, for example, store business hours or office hours. For example, if it is business from 9 am to 7 pm, it may be set from 8 am in the morning to 8 pm, including before and after that. The time set in this way is stored in the storage unit 5.

  Next, the control unit 3 displays an analog clock on the display unit (hereinafter referred to as an analog clock display unit). In addition, on the clock panel of the analog clock display unit, the power consumption predicted value is displayed in color on the concentric circle with the analog clock (hereinafter, power consumption predicted value display unit) (step 102).

  FIG. 3 is a diagram illustrating a display example of the display screen 20. An analog clock display unit 21 is displayed on the display screen 20. In the analog timepiece display unit 21, the long hand and the short hand move with time. That is, the analog clock display unit 21 functions as a normal clock. On the clock panel of the analog clock display unit 21, a power consumption predicted value display unit 25 is provided concentrically with the analog clock. In the power consumption predicted value display unit 25, the predicted value of the power consumption per predetermined time (for example, 30 minutes) in the set time range (12 hours from 8:00 am to 8:00 pm in the figure) is indicated by the color. Is displayed. For example, the power consumption is set to gradually change from green to orange to red as the power consumption increases.

  In the case of a set time range of 12 hours or more, the predicted value of power consumption may be overwritten as needed with the passage of time after a predetermined time has elapsed. In addition, a power consumption actual value display unit 23 is provided concentrically with the power consumption predicted value display unit 25. The power consumption actual value display unit 23 will be described later.

  Further, the control unit 3 displays the current power consumption in real time (hereinafter referred to as a power consumption real-time display unit) separately from the analog clock display unit. The power consumption real-time display unit 29 is, for example, a meter (semicircle) displayed on the left side of the display screen 20. The power consumption real-time display unit 29 is color-coded and displayed on the meter according to the power consumption, similarly to the power consumption predicted value display unit 25 described above.

  The power consumption real-time display unit 29 is a part that displays the current power consumption. The current power consumption is calculated every predetermined time (for example, 30 minutes) based on the power consumption from the calculation start time to the present time obtained from a power meter or the like, and the time from the calculation start time to a predetermined time later This is the equivalent amount of power consumption per unit. For example, when the calculation is started at 8 o'clock (at the start of calculation), the integrated power consumption from 8 o'clock to the present is calculated for 30 minutes until 8:30, for example, the integrated power consumption from 5 minutes before to the present From the slope, the power consumption conversion amount per hour is calculated by extrapolating the power consumption conversion amount after 30 minutes. The above calculation is performed, for example, every 30 seconds or every minute. At 8:30, the power consumption conversion amount is reset, and the power consumption conversion amount for 30 minutes from 8:30 is calculated in real time. Note that the power consumption conversion amount may be converted from the average power consumption from the start of calculation to the present time into the power consumption after 30 minutes. In this way, the control unit 3 acquires the power consumption information from the wattmeter, calculates the power consumption conversion amount (hereinafter simply referred to as “power consumption”), and displays it on the power consumption real-time display unit 29. To do. In addition, the power consumption conversion amount actually displayed on the power consumption real-time display unit 29 is displayed every 30 minutes by converting the power consumption conversion amount for 30 minutes into the power consumption for one hour.

  Further, the control unit 3 displays the target power setting unit 33 and the warning power setting unit 31 on the display screen 20. For example, normally, when the power consumption (converted to one hour) every 30 minutes exceeds contract power, it is necessary to pay a higher power charge. Therefore, it is necessary to save power so that the power consumption every 30 minutes (one hour equivalent) does not exceed the contract power. For example, the warning power may be set to about 90% of the contract power, and the target power may be set to about 80% of the contract power.

  Further, the control unit 3 displays a display switching button 27 on the display screen 20. The display switching button 27 can switch the target energy (for example, electric power and gas) to be displayed, or can display data of the past day.

  Next, the control unit 3 determines whether or not the current power consumption is higher than the set target power or warning power. (Step 103). When the current power consumption is lower than the target power or the warning power, the power consumption actual value display section 23 of the analog clock display section 21 is displayed at every power consumption conversion value calculation interval (for example, 30 minutes). The power consumption during that time is displayed by color (step 105).

  The control unit 3 repeats the above operation until a set time elapses (for example, 8:00 pm) (step 106). FIG. 4 is a diagram showing a state where the time is 14:15 as an example. In the above example, the actual power consumption value display unit 23 displays the actual power consumption value by color every 30 minutes. The color in the power consumption actual value display unit 23, the color in the power consumption predicted value display unit 25, and the color in the power consumption real-time display unit 29 are set with the same color coding for the power consumption. The Therefore, for example, the power consumption real-time display unit 29 can function as a color legend of each display unit.

  In addition, as shown in the figure, the power consumption predicted value display unit 25 may erase the color with time or may display it as it is. In addition, the power consumption actual value display unit 23 on the outer peripheral side and the power consumption predicted value display unit 25 on the inner peripheral side may display the inside and outside in reverse, as long as they are displayed concentrically with the clock panel. , Any position is acceptable.

  Next, the case where the power consumption monitored in real time exceeds the target power will be described. When the current power consumption (the power consumption conversion amount calculated from the power consumption at each time point until 30 minutes elapses from the start of calculation) exceeds the set power (target power), the control unit 3 displays The background color of the screen is changed and a warning screen is displayed (step 104).

  FIG. 5 is a diagram illustrating a state where the power consumption exceeds the target power. When the power consumption exceeds the target power, the control unit 3 first changes the color of the background 37 of the display screen 20. For example, the background 37 is normally set in an inconspicuous color such as green, but when the power consumption exceeds the target power, the background is changed to orange. Further, the control unit 3 displays a warning display 39 on the display screen 20. Further, the control unit 3 displays a guidance display 41.

  The warning display 39 is a word or a mark such as “caution”, for example. Further, the guidance display 41 is information such as the fact that the target power has been exceeded and power usage restrictions. For example, when the power consumption exceeds a predetermined value, if control is performed to reduce the amount of power used, such as decimating and lighting some lighting, etc., the details and warning of power saving etc. Is displayed.

  FIG. 6 is a diagram showing a state where the power consumption further exceeds the warning power. When the power consumption exceeds the warning power, the control unit 3 further changes the color of the background 37 of the display screen 20. For example, the background is changed to red. Further, the control unit 3 displays a warning display 39 on the display screen 20. Further, the control unit 3 displays a guidance display 41.

  The warning display 39 is a word or a mark such as “warning”, for example. The guidance display 41 is information such as the fact that the warning power has been exceeded and the use limit of power. For example, if the power consumption exceeds a specified value, the power supply for air conditioning, etc. is forcibly shut down, and if control is performed to reduce power consumption, the details and warnings to save power are displayed. Is done.

  As described above, when the power consumption exceeds the target power or the warning power, the user can easily exceed the predetermined power by changing the color of the background 37 and displaying the warning. Can be understood. Moreover, it can prevent beforehand that the power consumption for every 30 minutes exceeds contract electric power, for example.

  As described above, the power consumption displayed on the power consumption real-time display unit 29 is calculated by extrapolating from the power consumption at each point in time from the start of calculation to, for example, 30 minutes. This is the amount of power consumption converted later. Therefore, immediately after the start of the calculation, the power consumption is likely to be instantaneously changed, and the target power or the warning power may be instantaneously exceeded. Therefore, in the present invention, the control unit 3 sets a mask time for a predetermined period (for example, 5 minutes) from the start of calculation, and during this time, even if the power consumption exceeds the target power or the warning power, the color of the background 37 is changed. And warning display 39 are not performed. In this way, stable warning display can be performed.

  In addition, when the power consumption exceeds the target power or the warning power, the control unit 3 displays the screen when the power consumption is equal to or lower than the target power after the color change of the background 37 is performed. The normal display (for example, FIG. 3) is restored. The above is repeated until the set time elapses, and the power consumption for each time is displayed on the power consumption actual value display unit 23.

  After the set time has elapsed, the control unit 3 holds the display screen 20 in a state where the actual power consumption value for that day is displayed. Thereafter, for example, the actual power consumption value display unit 23 is cleared several hours before the set time, the next day's power consumption prediction is performed, and the power consumption predicted value display unit 25 displays the power consumption within the set time range. Display the predicted value. In addition, the control part 3 preserve | saves a power consumption actual value in the memory | storage part 5, and uses it as subsequent power consumption information.

  As described above, according to the present invention, since the predicted value and the actual value of the power consumption are displayed on the clock panel of the analog timepiece, the user can easily understand the relationship between the time and the power consumption, and the business hours, etc. The relationship between and can be easily grasped. In particular, since the power consumption is displayed by color, it is intuitively easy to understand.

  In addition, since the current power consumption is displayed in real time, it is possible to easily grasp the power consumption together with past results. At this time, if the current power consumption exceeds the target power or warning power, the background color is changed and a warning is displayed, so the user can confirm at a glance that the power consumption has exceeded the predetermined value. I can grasp it.

  At this time, by setting the mask time for a predetermined period from the start of calculation to calculate the conversion amount per hour with respect to the current power consumption, an error may occur due to instantaneous power consumption fluctuation immediately after the start of calculation. Display of a warning screen or the like.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, information other than energy consumption can be displayed together on the display screen. In this case, on the concentric circles of the clock face of the analog clock display unit 21, the outside air temperature (displays the temperature for each hour), the weather forecast (displays the weather for each hour), and the heat stroke attention level (above a predetermined temperature for each hour) Life information such as pollen dispersity (warning is displayed when pollen is expected to exceed a certain level), necessity of umbrella (mark is displayed when it is expected to rain) May be displayed. Such life information may display an actual value before the current time and a future prediction. By displaying such life information together, it is possible for the user to refer to a plan to go out and to make a power saving plan efficiently.
