Description

  The present invention relates to an energy saving diagnosis apparatus that monitors the usage time of resources generated by each operation of a plurality of control objects, and an energy saving diagnosis system using the same.

  Conventionally, various controllers for controlling a plurality of controlled objects have been proposed. Such a controller operates the controlled object or stops the controlled object operation by outputting a control command to each controlled object at a predetermined time according to predetermined schedule control information. Such a controller uses a time division multiplex transmission method for communication with each control object, and transmits a control command for operating the control object by sequentially communicating with a plurality of control objects, Status can be obtained.

  In recent years, energy conservation efforts for resources have become active in buildings and facilities. As an effort to save resources, it is conceivable to set a period during which the use of electric power, which is one of the resources, is permitted (usage permission period). When the usage permission period is set, the energy saving diagnosis system that monitors the power usage time of the control target determines whether the power usage by the operation of the control target is within the usage permission period, and based on the determination result, The electric power usage is displayed by distinguishing whether it is the usage permission period or not. Thereby, the user can stop using the resource by the operation of the controlled object outside the use permission period, and can promote the use in the use permission period.

  Furthermore, if the controller as described above is used, the user can control the schedule control information so that the use time is within the use permission period when the resource is used outside the use permission period according to the display of the energy saving diagnosis system. It is also possible to change. As a result, the use of resources due to the operation of the controlled object outside the use permission period is eliminated, and energy saving of resources can be achieved. In this way, when the user changes the schedule control information using the controller, if the user can confirm how much energy saving effect has been achieved by changing the schedule control information, Thus, further energy saving can be promoted.

  In contrast to this, data on the amount of power used (electricity usage) by the controlled object (electrical equipment) is stored sequentially in time series, and the power usage over different periods is compared and displayed. A system that can confirm the effect has been considered (see, for example, Patent Document 1). In the system described in Patent Document 1, when a certain period of time has elapsed since the time when an operation for requesting a comparison result was performed by a user, the amount of power used in a certain period before the operation time, Power consumption over a certain period of time.

Japanese Patent Laid-Open No. 2008-202985

  However, in the configuration of Patent Document 1, the user can grasp how the electricity usage has changed before and after the operation for requesting the comparison result, but the power usage associated with the change in the schedule control information. It is not possible to confirm the change. That is, even if the user changes the schedule control information using the controller, the comparison result displayed in response to the subsequent user operation directly represents the energy saving effect associated with the change in the schedule control information. is not.

  As a method for confirming the effect of energy saving accompanying the change in the schedule control information, the user records the resource usage time data before the change in the schedule control information in advance, and changes the schedule control information. It is also possible to evaluate the comparison result by comparing with later data. However, in this method, it is not easy for the user to confirm the effect of energy saving, so it is difficult to encourage the user to confirm the effect of changing the schedule control information and promote further energy saving. .

  The present invention has been made in view of the above-described reasons, and provides an energy saving diagnosis apparatus and an energy saving diagnosis system using the energy saving diagnosis apparatus that can easily confirm the effect of energy saving accompanying change in schedule control information. With the goal.

  An energy saving diagnosis apparatus according to the present invention is an energy saving diagnosis system for monitoring the usage time of resources generated by each operation of a plurality of control objects, and when a predetermined time is reached according to predetermined schedule control information, the control command is sent to the control object A control unit that controls the operations of the plurality of control objects by outputting to the information, an information acquisition unit that periodically acquires information on the usage state of the resource as usage information, and the usage information for acquiring the usage information.

The actual data is compared with the reference data using usage information as actual data.

  In this energy saving diagnostic apparatus, the comparative evaluation unit generates the reference data from the use information stored in the information storage unit, excluding the use information on a special day whose use time of the resource is different from a normal time. It is desirable to do.

  In this energy saving diagnostic apparatus, it is more preferable that the information storage unit stores, together with the usage information, special date information indicating whether or not the date when the usage information is acquired is the special date.

(Embodiment 1)
The energy-saving diagnosis system of this embodiment is a system that monitors the usage time of resources generated by each operation of a plurality of control objects. Hereinafter, a case where the energy saving diagnosis system is used in a store such as a supermarket and the resource is electric power will be described as an example.

  The energy saving diagnosis system 1 includes a controller 2 as an energy saving diagnosis device and a user terminal 3 as shown in FIG. A facility system 5 is connected to the energy saving diagnosis system 1.

  The equipment system 5 includes a plurality of control objects 51. Each control object 51 is a combination of a control terminal 52 having a relay and a lighting load 53. Each lighting load 53 is turned on and off according to on / off of the relay of the control terminal 52. Here, although the illumination load 53 is used as the control target 51 of the equipment system 5, a load other than the illumination load 53, such as an air conditioning facility, may be used as the control target.

  The user terminal 3 is a computer such as a personal computer managed by a store manager, and includes a display screen 31. As will be described in detail later, the user terminal 3 displays the lighting state of each lighting load 53 collected by the controller 2 on the display screen 31 using, for example, a Web browser.

  As shown in FIG. 1B, the controller 2 includes a terminal side communication unit 21, a display management unit 22, a control unit 23, a load side communication unit 24, a schedule setting unit 25, a storage unit 26, An information acquisition unit 27, a comparative evaluation unit 28, and a timer 29 are provided. The controller 2 communicates with the control terminal 52 of each control target 51 by the time division multiplex transmission method. A system in which a local control controller (not shown) is connected to the controller 2 and the plurality of control terminals 52, and data transfer between the controller 2 and the control terminal 52 is centrally managed by the local control controller. A configuration may be employed.

  The control unit 23 controls the lighting of the lighting load 53 by turning on / off the relay of the control terminal 52 designated by the preset schedule control information. The schedule control information is preset in a setting holding area constituting the schedule storage unit in the storage unit 26. The schedule control information is information that sets a specified time, a control object, and control contents (relay on / off) in association with each other.

  That is, according to the schedule control information in the storage unit 26, when the current time counted by the timer 29 reaches a specified time (predetermined time), the control unit 23 turns on / off the relay of the target control terminal 52 according to the control content. Generate a control command to switch. The control command is a command for causing the control target 51 to execute an operation to start or end the use of power. The control unit 23 that has generated the control command transmits the control command to the target control terminal 52 using the load side communication unit 24. Thereby, the operation of the control target 51 is controlled according to the schedule control information.

  The information acquisition unit 27 periodically acquires the ON / OFF state of each relay from each control terminal device 52 by periodically communicating with each control terminal device 52 using the load side communication unit 24. That is, the information acquisition unit 27 periodically acquires information on the on / off state of each control terminal 52, and constantly monitors the on / off state of each relay.

  Since the ON / OFF state of the relay of the control terminal 52 is linked to the lighting state of the lighting load 53, the information acquisition unit 27 monitors the lighting state of each lighting load 53 by monitoring the ON / OFF state of each relay. Will do. Thereby, the information acquisition unit 27 can periodically acquire information on the power usage state by the operation of each control target 51 as usage information and monitor the power usage time of each control target 51.

  The acquired usage information is stored in time series for each control target 51 in association with the date and time information acquired in the data holding area constituting the information storage unit in the storage unit 26.

  In addition, the information acquisition unit 27 outputs information about the ON / OFF state of each relay, that is, the lighting state of each lighting load 53 collected from each control terminal 52 to the display management unit 22.

  When the information on the ON / OFF state of the relay of each control terminal 52 is input from the control unit 23, the display management unit 22 generates data for displaying the information on the ON / OFF state of each relay on the user terminal 3. The display management unit 22 transmits the generated data to the user terminal 3 using the terminal side communication unit 21.

  The terminal-side communication unit 21 is connected to the Internet 6 that is an external network using Ethernet (registered trademark), and similarly configured to be able to communicate with the user terminal 3 connected to the Internet 6. Yes. Accordingly, the display management unit 22 receives a request from the user terminal 3 via the Internet 6 and displays the generated data on the display screen 31 of the user terminal 3.

  Here, the display management unit 22 sets a period during which the use of power is permitted in advance as a use permission period, and distinguishes whether or not the use of power corresponding to the acquired use information is within the use permission period. It can be displayed on the terminal 3. The use permission period is set in advance for each control target 51 and stored in the setting holding area of the storage unit 26.

  In other words, the user terminal 3 uses the usage information acquired by the information acquisition unit 27 and displays the usage time of the power by distinguishing whether it is within the usage permission period as shown in FIG. In FIG. 2, 32 represents use during the use permission period, and 33 represents use outside the use permission period.

  The user terminal 3 displays the power usage state every predetermined period (for example, 10 minutes). For example, when the predetermined period is 10 minutes, if the power is used for a little (for example, 1 minute) of the predetermined period of 10 minutes, the user terminal 3 uses the power for the entire predetermined period. Is displayed. That is, even when power is used for only a short time or when power is used continuously for 10 minutes, it is displayed on the user terminal 3 in the same way at the target predetermined period.

  The schedule setting unit 25 has a function of setting schedule control information used for controlling the control target 51 by the control unit 23. In the present embodiment, the schedule setting unit 25 is configured to reflect the schedule control information set on the display screen 31 of the user terminal 3 as shown in FIG.

  That is, in FIG. 2, schedule control information is set by an on control point 34 that represents a designated time to be turned on for each control target 51 and an off control point 35 that represents a designated time to be turned off. Thereby, the control unit 23 controls each control object 51 to be in an on state (lighted state) during a period between the on control point 34 and the off control point 35.

  The on control point 34 and the off control point 35 can be slid in the time axis direction on the display screen 31 of the user terminal 3 using a mouse or the like, and the schedule control information is adjusted by adjusting the positions of these control points. Adjust. When a registration button (not shown) on the display screen 31 is pressed, the schedule setting unit 25 updates the schedule control information in the storage unit 26 according to the positions of the on control point 34 and the off control point 35 at that time. To do.

  By providing the schedule setting unit 25 as described above, the user can easily change the schedule control information while confirming whether or not the use of power is within the use permission period in the user terminal 3. Is possible. Note that the method for changing the schedule control information is not limited to the method described above. For example, the schedule control start and end times in the table displayed at the bottom of FIG. Good.

  When the evaluation mode is set, the comparative evaluation unit 28 has a function of comparing the power usage time before and after the start of the evaluation mode. The comparison result in the comparative evaluation unit 28 is output to the display management unit 22, transmitted to the user terminal 3 by the terminal side communication unit 21, and displayed on the display screen 31. That is, the user terminal 3 has a function as a display unit that displays a comparison result by the comparative evaluation unit 28.

  In the energy saving diagnosis system 1 of the present embodiment, the comparative evaluation unit 28 sets the time when the schedule control information is changed by the schedule setting unit 25 as the start time of the evaluation mode. Specifically, the display management unit 22 is shown in FIG. 3 when the positions of the on control point 34 and the off control point 35 are adjusted on the display screen 31 and the schedule control information is changed by pressing the registration button. Such a dialog is displayed on the display screen 31.

  The dialog illustrated in FIG. 3 is a screen for confirming whether or not the evaluation mode (hereinafter also referred to as “eco-challenge”) is to be performed, and whether or not to be performed for each control target (load point name) 51. It has a check column 36 for confirmation. At this time, when the registration button 37 is pressed while any one of the check fields 36 is checked, the comparative evaluation unit 28 starts an evaluation mode (eco-challenge) for the control target 51 that is checked. . The date and time when the evaluation mode is started is stored in the setting holding area of the storage unit 26.

  When the evaluation mode starts, the comparative evaluation unit 28 uses, as reference data, usage information for a certain period (for example, in units of days, weeks, months, and years) before the start time of the evaluation mode, and is constant after the start time. Both are compared using the usage information for the period as actual data. Here, the comparative evaluation unit 28 reads the usage information for the period to be the target of the reference data from the data holding area of the storage unit 26 in which the usage information is stored in time series, and sets the reference data as the target of the actual data. The usage information for the period to be read out is used as actual data.

  For example, when a certain period of time serving as reference data for the evaluation mode is set to one week, the comparative evaluation unit 28 is for one week from one week before the start date of the evaluation mode to the day before the start date of the evaluation mode. Use information is used as reference data. In this case, the comparative evaluation unit 28 uses the usage information for one week after the start date of the evaluation mode as the actual data, compares the actual data with the reference data, and causes the user terminal 3 to display the comparison result.

  Thereby, for example, as shown in FIG. 4, the user terminal 3 controls the load point 41 representing the control target 51, the challenge setting date 42 representing the start date of the evaluation mode, the comparison result 43, and the ratio 44. A table is displayed for each target 51. In FIG. 4, the comparison result 43 or the like is displayed for only one control object 51, but actually, the comparison result 43 or the like is displayed for each of the plurality of control objects 51.

  The comparison result 43 is displayed in the format of actual time / reference time, where the power usage time corresponding to the reference data is the reference time and the power usage time corresponding to the actual data is the actual time. The ratio 44 represents the ratio of the power usage time represented by the actual data to the power usage time represented by the reference data as a numerical value. Further, a challenge mark 45 indicating whether or not the evaluation mode is being executed is displayed beside the challenge setting date 42, and an increase / decrease display 46 indicating increase / decrease in power usage time is displayed beside the ratio 44.

  The ratio 44 is calculated by dividing the actual time by the reference time, and is displayed here as a percentage (%). That is, if the actual time decreases from the reference time, the ratio 44 is less than 100 (%), and conversely if the actual time increases from the reference time, the ratio 44 exceeds 100 (%). .

  Here, the comparative evaluation unit 28 rounds up the lowest value (first decimal place) when the ratio 44 is calculated. As a result, when the actual time is shorter than the reference time, for example, when the actual time / reference time = 97.5 (%), the displayed ratio 44 is 98 (%), so the energy is excessive for the user. Reduced to not appear. On the other hand, when the actual time is longer than the reference time, for example, when the actual time / reference time = 103.4 (%), the displayed ratio 44 is 104 (%). The increase will not be underestimated. In short, compared to the case where the lowest value at the time of calculating the ratio 44 is rounded down or rounded off, the user can see an excessive effect of energy saving, or the increase in power usage time can be seen less. There is an advantage that there is nothing.

  The increase / decrease display 46 represents the increase / decrease in the power usage time before and after the start time of the evaluation mode by the direction of the arrow. Here, a threshold value for determining the direction of the increase / decrease display 46 is set with respect to the ratio 44, and the threshold value is set to ± 3 (%) of 100 (%), for example. In this case, the increase / decrease display 46 is an upward arrow indicating an increase in power usage time if the ratio 44 is greater than 103 (%), and a downward arrow indicating a decrease in power usage time if the ratio 44 is greater than 97 (%). It becomes. If the ratio 44 is in the range of 100 ± 3 (%), the increase / decrease display 46 becomes a horizontal (rightward) arrow. The controller 2 may be configured such that a threshold value for determining the direction of the increase / decrease display 46 can be arbitrarily set by an operation input from the user terminal 3.

  That is, the user confirms how the power usage time has changed before and after the start of the evaluation mode by confirming the display as shown in FIG. 4 on the display screen 31 of the user terminal 3. be able to. Here, since the start point of the display mode is the change point of the schedule control information, as a result, the user can confirm the effect of energy saving accompanying the change of the schedule control information. Moreover, since the ratio 44 quantitatively represents the energy saving effect and the increase / decrease display 46 qualitatively represents the energy saving effect, there is an advantage that the user can easily understand the energy saving effect. .

  FIG. 4 shows an example in which the actual data and the reference data are compared for each control target 51 and the comparison result is displayed. However, the plurality of control objects 51 are grouped, and the actual data and the reference data are grouped for each group. May be compared, and the comparison result may be displayed. For example, the group is set in advance so that a plurality of control objects 51 installed in the same area are set as one group, and is specified by a group name (for example, “sales area”) added to each group.

  In addition, when the evaluation mode is set a plurality of times for the same control target 51, the comparative evaluation unit 28 compares the power usage time before and after the start of the latest evaluation mode.

  Next, the relationship between the reference data compared by the comparative evaluation unit 28 and the implementation data will be described in detail.

  Normally, when comparing the power usage time for one week, the power usage time for one week from one week before the viewing date of the comparison result to the previous day is used as the implementation data, and the power for one week one week before that is used. It is common to compare both using the usage time as reference data.

  That is, as shown in FIG. 5, if the browsing date D1 of the comparison result is June 4, and one week from May 28 to June 3 is the execution data acquisition period D2, it corresponds to the previous week. One week from May 21 to May 27 is the reference data acquisition period D3. Similarly, when comparing the power usage time for one day, if June 3 is set as the execution data acquisition period D4, May 27, one week before, becomes the reference data acquisition period D5. If the 29th is defined as the implementation data acquisition period D4, May 22 becomes the reference data acquisition period D5.

  On the other hand, in this embodiment, when comparing the power usage time for one week, the comparative evaluation unit 28 starts from one week before the start date of the evaluation mode regardless of the viewing date of the comparison result (see FIG. 4). The power usage time for one week until the day before the start date of the evaluation mode is used as reference data.

  That is, as shown in FIG. 6, if the start date D0 of the evaluation mode is May 28, it may be from May 21 to May 27 corresponding to the previous week of the start date D0, regardless of the browsing date D1 of the comparison result. One week is the reference data acquisition period D3. On the other hand, if the viewing date D1 of the comparison result is June 16, the week from June 9 to June 15 of the previous week is the execution data acquisition period D2. Similarly, when comparing the power usage time for one day, if June 10 is set as the acquisition period D4 of the implementation data, June 10 before the evaluation mode start date (May 28) D0 May 27, the same day of the week, is the reference data acquisition period D5. Further, if June 15 is an execution data acquisition period D4, May 25, which is the same day of the week as June 15, prior to the evaluation mode start date (May 28) D0, is the reference data acquisition. Period D5 is entered.

  Note that the length of the evaluation mode duration D6 is set in advance, and in the example of FIG. 6, June 25, four weeks after the start date D0 of the evaluation mode, is the end date D7 of the evaluation mode. The comparative evaluation unit 28 can set an arbitrary period within the evaluation mode duration period D6 as an execution data acquisition period.

  The comparative evaluation unit 28 operates according to the rules as shown in FIG. 6 while the evaluation mode is set, and is based on the general rules as shown in FIG. 5 while it is not set to the evaluation mode. It may be configured to operate in a normal mode for generating data and implementation data. In this case, when changing the schedule control information, the user operates the comparative evaluation unit 28 in either the evaluation mode or the normal mode depending on whether or not the check column 36 is checked in the dialog as shown in FIG. Can be selected.

  By the way, if the usage information that is the base data includes usage information for special days (for example, closed days of stores, days when business hours are different from normal times) or usage information that lacks data, The reliability of the reference data is lowered. Data loss may occur due to a system stoppage due to, for example, a communication error between the controller 2 and the control terminal 52 or a power failure. In other words, since the power usage time on a special day or when data is lost is significantly different from the normal power usage time, the reference data is the usage information for such a special day or period when data is missing. It is desirable to be generated except for.

  Therefore, in the present embodiment, the comparative evaluation unit 28 generates reference data from the usage information stored in the storage unit 26 by excluding the usage information for special days and the usage information for which data is missing. More specifically, if the date (hereinafter referred to as “default date”) from which the reference data is acquired is a special date or a date when data loss occurs, the comparative evaluation unit 28 goes back one week before that date. To obtain reference data. Further, if the special date or the date of data loss occurs one week before the default date, the comparative evaluation unit 28 further acquires the reference data retroactively one week before that date.

  The comparative evaluation unit 28 repeats the same operation a predetermined upper limit number of times, thereby generating the reference data excluding the usage information on the special day and the date when the data is lost. Note that the upper limit number of repetitions is determined by the number of days of use information that can be stored in the data holding area of the storage unit 26.

  For example, as shown in FIG. 7, when the viewing date D1 of the comparison result is May 28 and May 27 of the previous day is the execution data acquisition period D5, May 20 one week before is The default date is D8. If the default date D8 is a special date or a date on which data loss occurs, the comparative evaluation unit 28 uses the usage information on May 13 one week before as reference data. If May 13 is also a special day or a date when data loss occurs, the comparative evaluation unit 28 acquires the reference data by going back to May 6 and April 29 one week before.

  However, if all the dates back from the default date to the upper limit number are special dates, the comparative evaluation unit 28 uses the default date usage information as reference data, and the special date indicates that the reference data is special date information. Set the flag. Further, if any of the dates going back to the upper limit number from the default date is a date on which data loss has occurred, the comparative evaluation unit 28 sets the error flag without generating the reference data as no target date.

  When the special day flag or the error flag is set, the comparative evaluation unit 28 causes the user terminal 3 to display a warning indicating an abnormal value for at least one of the ratio 44 and the increase / decrease display 46 described above. . Specifically, the comparative evaluation unit 28 displays a warning by displaying the ratio 44 and the increase / decrease display 46 in a color different from that in the normal state or displaying “−”. Thereby, it is possible to prevent the user from erroneously recognizing the effect of energy saving associated with the change in the schedule control information because the user trusts the data with low reliability as it is.

  The comparative evaluation unit 28 is not limited to the configuration for generating the reference data except for both the usage information for the special day and the usage information for which the data is missing, and the usage information for the special day and the data are missing. The configuration may be such that the reference data is generated except for any one of the usage information.

  In the present embodiment, special date information indicating whether or not the date when the information acquisition unit 27 acquires the usage information is a special date is stored in the data holding area of the storage unit 26 together with the usage information. As a result, the comparative evaluation unit 28 can determine whether or not it is a special day based on the special day information stored in the storage unit 26, so that the process of generating the reference data excluding the special day use information is simple. become.

  Here, in the setting holding area of the storage unit 26, calendar information in which a special day is set in association with a date or day of the week is stored in advance, and the comparative evaluation unit 28 also uses the calendar information as usage information. It can be determined whether or not the corresponding date is a special day. However, the comparative evaluation unit 28 can correctly determine whether or not it is a special day by using the special date information stored in the storage unit 26 even if the calendar information is changed. There is an advantage. For example, if the store's holiday was previously 10th of every month, but the store's holiday was changed to the 20th of every month, the comparative evaluation unit 28 uses the information acquired on the 10th before the change of the holiday. Can be correctly determined as a special day from the corresponding special day information.

  Next, the operation of the energy saving diagnostic system 1 according to the present embodiment will be described with reference to FIG.

  First, the user terminal 3 receives an operation input from the user and displays a schedule chart (see FIG. 2) including the on control point 34 and the off control point 35 of the schedule control information on the display screen 31 (S1). At this time, the user terminal 3 requests the controller 2 for data for performing the display, and receives a reply from the controller 2.

  The user terminal 3 changes (improves) the schedule control information in response to an operation input from the user in a state where the schedule chart is displayed (S2), and transmits and registers the changed contents to the controller 2 (S3). ). At this time, the user terminal 3 displays a dialog (see FIG. 3), causes the user to select whether or not to implement the eco challenge (evaluation mode), and transmits the result to the controller 2 (S4).

  When execution of the eco challenge is selected (S5), a registration setting command for causing the controller 2 to start the eco challenge is transmitted from the user terminal 3. When non-execution of the eco challenge is selected (S6), a cancel setting command for ending the eco challenge is transmitted from the user terminal 3 to the controller 2.

  Thereafter, the user terminal 3 receives an operation input from the user, and displays on the display screen 31 an energy saving front screen representing the comparison result of the comparative evaluation unit 28 based on the eco challenge as illustrated in FIG. 4 (S7). At this time, the user terminal 3 requests the controller 2 for data for performing the display, and receives a reply from the controller 2. The controller 2 receives a request for data from the user terminal 3, determines whether or not the eco-challenge is performed for each control target 51 (S8), and arranges data to be displayed on the user terminal 3 (S9).

  Thereby, the user can confirm the effect of the energy saving accompanying the change of schedule control information by confirming the comparison result of the comparative evaluation part 28 by the eco challenge on the display screen of the user terminal 3. (S10). If there is an energy saving effect, the schedule control information may be used as it is, but if there is no energy saving effect, it is desirable to return to step S1 and further change the schedule control information.

  Next, details of the processes S8 and S9 performed when the controller 2 receives a data request from the user terminal 3 will be described with reference to FIG.

  First, the comparative evaluation unit 28 reads the date when the eco-challenge is started from the setting holding area of the storage unit 26 (S11), and reads the usage information as the actual data from the data holding area of the storage unit 26 (S12). . Further, the comparative evaluation unit 28 reads use information as reference data from the data holding area of the storage unit 26 based on the start date of the eco-challenge (S13). At this time, the comparison / evaluation unit 28 checks whether the usage information serving as the reference data includes usage information for special days or usage information for which data is missing. Reference data is acquired (S14).

  When the result data (Result) and the reference data (Standard) are acquired, the comparative evaluation unit 28 calculates the ratio (result data / reference data) between the two (S15) and transmits the calculation result to the user terminal 3. (S16).

  According to the configuration described above, in the energy saving diagnosis system 1 of the present embodiment, the comparative evaluation unit 28 sets the time when the schedule control information is changed as the start time of the evaluation mode, and schedule control information that is the start time of the evaluation mode. Compare the power usage time before and after the change. That is, the comparative evaluation unit 28 uses, as reference data, usage information for a certain period before the time point when the schedule control information is changed, regardless of the viewing date of the comparison result. Therefore, the user confirms on the display screen 31 of the user terminal 3 how the power usage time has changed before and after the start of the evaluation mode, thereby saving energy associated with the change in the schedule control information. The effect of can be easily confirmed.

  Moreover, since the comparative evaluation part 28 produces | generates reference | standard data from the usage information memorize | stored in the memory | storage part 26 except for the usage information and the usage information from which data are missing, it is normal electric power usage time. Usage information that is significantly different from the above is not reflected in the reference data. As a result, the reliability of the reference data is increased, and the reliability of the comparison result of the comparative evaluation unit 28 is also improved.

  By the way, in the present embodiment, an example is shown in which the evaluation mode starts when the registration button 37 is pressed while the check column 36 is checked in the dialog shown in FIG. The configuration may be such that the evaluation mode automatically starts. That is, when the schedule control information is changed so as to reduce the power usage time, the schedule setting unit 25 evaluates the control target 51 whose schedule control information has been changed without displaying the dialog as shown in FIG. Start the mode automatically. When the schedule control information is changed so as to reduce the power usage time, for example, when the ON control point 34 is delayed, when the OFF control point 35 is advanced, or when the OFF period of the control target 51 increases. Etc.

  By adopting a configuration in which the evaluation mode automatically starts in this way, when the schedule control information is changed so as to reduce the power usage time, the user is not aware of the change in the schedule control information. The effect of energy saving can be confirmed by the user.

  Further, the comparative evaluation unit 28 may be configured to acquire the reference data from the period belonging to the same season as the date according to the date when the performance data is acquired. Thereby, for example, with respect to a load whose operation time varies depending on the season, such as an outdoor lighting load, the comparative evaluation unit 28 can accurately obtain the effect of energy saving accompanying the change of the schedule control information.

  The resource to be monitored by the energy saving diagnosis system 1 is not limited to electric power (amount of electricity) but may be water, gas, or heat. For example, when the resource is water or gas, a water pipe or a gas pipe for supplying water or gas is provided for each area in a building such as an office or a store. Then, by installing a valve for opening and closing the flow path of water and gas in the water pipe and the gas pipe, and monitoring the open / closed state of the valve, the use state (use / non-use) of water and gas can be monitored. Further, even when the resource is heat, a use state (use / non-use) of heat can be monitored by installing a valve for opening and closing the flow path of the heat medium and monitoring the open / close state of the valve.
