FIG. 5 shows the time of processing executed by four elements (air conditioning equipment 50a, 50b,..., Controllers 10a, 10b,..., Remote management server 20 and management terminal 30) involved in the creation of the report. It shows the relationship and the flow of data passed between the elements. In FIG. 5, the flow of time is defined from top to bottom.

  The headquarters 3 staff remotely manages the energy-saving operation rules applied to the stores 1a, 1b,... Via the Web browser of the management terminal 30 in the form of operation schedules of the air conditioning facilities 50a, 50b,. Upload to the server 20 (step S1). The operation schedule can be different for each of the air conditioners 50a, 50b,.

  The operation schedules of the air conditioning equipment 50a, 50b,... Uploaded to the remote management server 20 are the controllers 10a, 10b,. (Step S2).

  By the way, as above-mentioned, controller 10a, 10b, ... acquires the apparatus information of air-conditioning equipment 50a, 50b, ... every 1 minute, respectively. Based on the device information, the controllers 10a, 10b,... Calculate the amount of increased energy and the amount of energy saved during regular communication with the remote management server 20 at 30-minute intervals (step S3).

  The amount of increased energy is quantified according to a predetermined rule that contributes to increased energy more than the operation schedule among the violation operations of the air conditioning equipment 50a, 50b,... Contrary to the operation schedule for the last 30 minutes. Is. The amount of energy saving is quantified according to a predetermined rule that contributes to energy saving rather than the driving schedule among the violating actions of the air conditioning equipment 50a, 50b,... Contrary to the driving schedule for the last 30 minutes. is there. The rules include violation time (time when violation action was performed), violation time converted into basic unit, violation energy amount (energy amount increased or decreased from predetermined energy amount due to violation operation), converted into basic unit. The amount of violation energy and the number of violation operations of the remote controller 56 are calculated. The amount of energy can be calculated, for example, by multiplying the violation time by a value obtained by subtracting the set temperature according to the operation schedule from the actual set temperature. In step S3, the energy increase amount and the energy saving amount are calculated for each indoor unit 52. That is, the energy increase amount and the energy saving amount calculated in step S3 serve as an index representing the degree of violation for 30 minutes from the previous execution of step S3 to the current execution for each indoor unit 52.

  Thereafter, the controllers 10a, 10b,... Receive the data on the increased energy amount and the energy saving amount calculated in step S3 together with the device information for the last 30 minutes during the regular communication with the remote management server 20. (Step S4).

  On the other hand, the remote management server 20 stores the energy increase amount and energy saving amount data sent from the controllers 10a, 10b,... In the violation amount database 25b (step S5). The violation amount database 25b is a database in a tabular format as shown in FIG. 3, and is for each indoor unit 52 and for a period (the time width is 30 minutes. For example, “from 15:00 on January 15, 2009 to 10:00 on the same day. Data indicating the amount of increased energy and the amount of energy saving (defined as “half”) are held as one record.

  After steps S3 to S5 are repeated many times, if the amount of energy increase and energy saving sufficient to create a report has been accumulated in the violation amount database 25b, The remote management server 20 can be requested to distribute the report at an arbitrary timing (step S6). The report distribution command is uploaded to the remote management server 20 via the Web browser of the management terminal 30 by the staff of the headquarters 3 together with various parameters that determine the report format.

  The remote management server 20 executes step S7 for creating a report as soon as a report delivery request is received. The report created in step S7 is downloaded from the communication unit 21 of the remote management server 20 to the management terminal 30 and displayed on the web browser (step S8).

(7) Contents of report Hereinafter, referring to FIG. 6 to FIG. 9, items for evaluating the degree of penetration of the energy saving operation rules for the stores 1a, 1b,. explain.

7a) Compliance rate The compliance rate is the unit target (store 1a, 1b, ..., department or indoor unit) that does not exceed the prescribed threshold for the amount of violation of the operation schedule in the unit period (day, week, month, year, etc.) 52) and is calculated by the report creation unit 22c. The violation amount is an arithmetic average value of the increased energy amount and the energy saving amount, and is calculated by the violation amount calculation unit 22a. The unit period, the unit object, and the threshold value are determined by parameters input by the staff of the headquarter 3 in step S6 that requests the creation of a report.

  More specifically, the violation amount calculation unit 22a refers to the indoor unit database 25a and the violation amount database 25b, and the unit period of all the indoor units 52 belonging to each unit target (each store, each department, or each indoor unit). Calculate the arithmetic mean value of the total amount of energy increase and the total energy saving amount in, and use it as the violation amount. The indoor unit database 25a is a tabular database as shown in FIG. 3, and data indicating the affiliation of each indoor unit 52 (which department of which store 1a, 1b,...) Is one record. Hold as. Subsequently, the report creating unit 22c counts the number of unit targets (violation targets) whose violation amount is less than or equal to a threshold (for example, less than 0, that is, on the energy saving side), and the ratio of the number of violation targets to the total number of unit targets Is calculated as the compliance rate.

  The report creation unit 22c calculates a compliance rate in each of the immediately preceding unit period, the unit period immediately preceding the period, and the unit period immediately preceding the period. The three compliance rates in the three periods are output side by side on the report so that the comparison is easy. Therefore, the staff at headquarters 3 can easily grasp the time transition of the compliance rate.

  In addition, the arithmetic mean value of the energy increase amount and the energy saving amount is calculated on a daily basis, and only the arithmetic mean value on the day when the arithmetic mean value of the day increases (that is, becomes 0 or more). It is good also as a violation amount.

7b) Average value, median value, and mode value The report creation unit 22c refers to the indoor unit database 25a and the violation amount database 25b, and calculates the average value and the median value of the violation amount data group in the unit period for each unit target. And calculate the mode. The median is the value of the violation amount where the number of unit objects is in the middle, and the mode is the value of the violation amount where the number of unit objects is the maximum.

  More specifically, the report creating unit 22c determines the average value, median value, and maximum value of the violation amount in each of the immediately preceding unit period, the immediately preceding unit period, and the immediately preceding unit period. Calculate the mode value. The three sets of average value, median value, and mode value in the three periods are output side by side on the report so that comparison is easy. Therefore, the staff of the headquarters 3 can easily grasp the time transition of the average value, median value, and mode value of the violation amount.

7c) Variance and Standard Deviation The report creation unit 22c calculates the variance and standard deviation of the violation amount data group in the unit period for each unit object while referring to the indoor unit database 25a and the violation amount database 25b.

  More specifically, the report creating unit 22c calculates the variance and standard deviation of the violation amount in each of the immediately preceding unit period, the unit period immediately preceding the period, and the unit period immediately preceding the period. . In addition, the three sets of variances and standard deviations in the three periods are output side by side on the report for easy comparison. Accordingly, the staff of the headquarters 3 can easily grasp the dispersion of the violation amount and the standard deviation, that is, the time transition of the variation of the violation amount.

7d) Distribution graph The report creation unit 22c refers to the indoor unit database 25a and the violation amount database 25b, and creates a distribution graph of the number of unit objects for each violation amount as shown in FIG. Output above. In FIG. 6, stores 1a, 1b,... Are adopted as unit objects, and weeks are adopted as unit periods.

  More specifically, the report creation unit 22c creates a frequency distribution of unit objects for each violation amount by dividing the violation amount axis by a predetermined width and counting the number of violation amounts that fall within each width. The frequency distribution is graphed in a two-dimensional plane with the horizontal axis as the amount of violation and the vertical axis as the number of unit objects.

  The report creation unit 22c displays a distribution graph corresponding to the immediately preceding unit period (see the distribution graph for “this week” in FIG. 6), and a distribution graph corresponding to the unit period immediately preceding that period (“last week” in FIG. 6). And a distribution graph corresponding to the unit period immediately before the period (see the distribution graph of “last week” in FIG. 6). Three distribution graphs in the three periods are arranged so as to overlap in the same two-dimensional plane. In addition, the average value and the median value of violation amounts in the immediately preceding unit period are also clearly shown in the same two-dimensional plane (see FIG. 6). Therefore, the staff of the headquarters 3 can easily grasp the time transition of the distribution graph.

  In FIG. 6, the absolute number of unit objects is taken on the vertical axis, but other values reflecting the number of unit objects such as the ratio of unit objects can also be adopted.

7e) Mountain Characteristics The mountain deriving unit 22b derives the mountains that appear on the three distribution graphs while referring to the indoor unit database 25a and the violation amount database 25b. In the present specification, “mountain” includes the meanings of both the entire distribution graph and the bumps of the distribution graph. Hump means the area around the maximum point of the distribution graph. For example, the surrounding area is the minimum point immediately to the left of the maximum point and the minimum point to the right (minimum point to the left or right). If there is no, it can be defined as the area between the left and right edges of the distribution graph. In the example of the distribution graph shown in FIG. 6, there is one hump on the increased energy side (area where the violation amount is 0 or more) and one on the energy saving side (area where the violation amount is 0 or less).

  Moreover, the maximum point and the minimum point of the distribution graph for specifying the hump can be calculated by the following procedure, for example. That is, in creating the distribution graph, the frequency distribution of the unit target for each violation amount is created, and the list of the frequency distribution is sorted in ascending order according to the violation amount. Then, the point where such a list is traced from end to end and the increasing tendency turns into a decreasing tendency is the maximum point, and the point where the decreasing tendency turns into an increasing tendency is the minimum point.

  When the mountain is derived by the mountain deriving unit 22b, the report creating unit 22c derives an evaluation comment on the degree of penetration of the energy-saving operation rules for the entire unit object based on the characteristics of the mountain and outputs the comment on the report . The characteristics of the mountain include, for example, the number of mountains, the position of the mountain, the interval between mountains when there are multiple mountains, and the height of the mountain. The evaluation comment is derived with reference to tabular data as shown in FIG. 7 stored in the storage unit 25. In the table of FIG. 7, there are four columns of “item”, “evaluation criteria”, “evaluation”, and “remarks”, but it is determined that the items in the “item” column meet the conditions described in the “evaluation criteria” column. In this case, the descriptions in the “evaluation” column and the “remarks column” are derived as evaluation comments. That is, the table in FIG. 7 is a table that holds evaluation comments corresponding to specific modes of the mountain characteristics.

  As shown in FIG. 7, when there are a plurality of humps, “There is a problem” “There is a problem in a specific unit target (the driving schedule does not match the unit target or the driving schedule is not kept”). In general, if the driving schedule matches the unit target, the distribution graph is expected to have a bell mouth shape like a normal distribution, but on the contrary, there are multiple humps. This is because the driving schedule itself may not be appropriate in the case where the position of the hump exists on the energy increase side (area where the violation amount is 0 or more). “Not penetrating” is included in the evaluation comment.If the hump-to-hump interval is wide, there are “problems” and “problems with a specific unit target (the operation schedule is Pitch to not or operation schedule is not followed, "is included in the evaluation comment.

  On the other hand, when the height of the entire distribution graph is low, or when the width of the entire distribution graph is wide, “there is a problem” and “the driving schedule is not thoroughly implemented” are included in the evaluation comment. Whether the width of the entire distribution graph is wide or narrow can be measured by the variance of the distribution graph or the standard deviation. In the example of FIG. 6, the height of the entire distribution graph is the maximum value in the vertical axis direction of the entire distribution graph, and the width of the entire distribution graph is the width of the entire distribution graph in the horizontal axis direction. That is.

7f) Other evaluation comments The table in FIG. 7 holds evaluation comments corresponding to specific modes of other items in addition to evaluation comments corresponding to specific modes of mountain characteristics. When the determination is made, the following evaluation comment is derived by the report creation unit 22c and output on the report.

  As shown in FIG. 7, the number of monitoring targets (the number of all unit targets to be monitored regardless of whether or not the data on the amount of energy increase and the amount of energy saved is collected) and the number of objects to be evaluated (the amount of energy increase and energy saving) If there is a deviation from the number of unit objects from which the amount of data has been collected), “there is a problem” and “there are unit objects that have escaped the driving schedule” are included in the evaluation comment. Note that the number of monitoring targets is derived by referring to the indoor unit database 25a.

  Also, if the compliance rate is below the threshold, the average value is on the energy-saving side, the average value is above the threshold with the energy-saving side negative, the median is on the energy-saving side, the median is energy-saving If the value is above the threshold with the side negative, or if the variance or standard deviation is greater than the threshold, “problem” and “driving schedule not permeated” are included in the evaluation comment. When the difference between the average value and the median value is larger than the threshold value, “problem” and “the driving schedule is not kept” are included in the evaluation comment. If the median value is on the increased energy side rather than the average value, “problem” and “the driving schedule has not penetrated” are included in the evaluation comment. Note that the various threshold values are determined by parameters input by the staff of the headquarter 3 in step S6 requesting the creation of a report.

  In addition, the current and previous results are also compared. More specifically, as shown in FIG. 7, when the height of the mountain (distribution graph as a whole or the hump) on the increased energy side is increasing, “problem” and “driving schedule cannot be observed” Is included in the evaluation comment. When the height of the mountain on the energy saving side (the entire distribution graph or hump) is decreasing, “no problem” and “no problem if the operating schedule penetration has increased” are included in the evaluation comment. It is done. If the compliance rate is decreasing, the average value is shifting in the direction of increasing energy, the median is shifting in the direction of increasing energy, or if the variance or standard deviation is increasing, "Problem" and "Driving schedule is not being followed" are included in the evaluation comment. Accordingly, the staff of the headquarters 3 can easily grasp the change in the degree of penetration of the energy saving operation rules with time.

  The table itself in FIG. 7 is also output on the report so that the meaning of the various output data can be easily understood.

7g) Analysis by time zone and day of week The report creation unit 22c refers to the analysis by time zone as shown in FIG. 8A and FIG. 8 (b) while referring to the indoor unit database 25a and the violation amount database 25b. Create a graph of the analysis results for each day of the week as shown in b) and output it on the report.

  In the two-dimensional plane of FIG. 8 (a), the time axis is taken on the horizontal axis, the proportion of unit objects on the energy increase side (violation amount is 0 or more) is taken on the vertical axis, and the vertical axis is on the vertical axis. The violation amount (more specifically, the cumulative value of the violation amount of all unit targets or the average value thereof) is taken. In the two-dimensional plane of FIG. 8B, the horizontal axis indicates the day of the week, the vertical axis indicates the percentage of the unit target on the energy increase side (violation amount is 0 or more), and the vertical axis indicates a violation. The amount (more specifically, the cumulative value of the violation amounts of all unit targets or the average value thereof) is taken. In addition, a line (30% line in the figure) that is a predetermined reference for management is drawn in the upward and downward directions of the vertical axis in each two-dimensional plane.

  Therefore, from the graphs shown in FIGS. 8A and 8B, the driving schedule generally matches the unit target for the time zone and day of the week when the percentage of the unit target on the energy increase side exceeds the line. Can not be read easily. In addition, the driving schedule does not match the specific unit target for the time zone and day of the week when the percentage of the unit target on the increased energy side does not exceed the line even though the violation amount exceeds the line Or whether a specific unit object deviates from the operation schedule can be easily read. The interpretation may be explicitly output as an evaluation comment on the report by causing the report creation unit 22c to perform the interpretation. In order to enable the interpretation by the report creation unit 22c, a table holding evaluation comments corresponding to specific modes of the graph, such as the table of FIG. 7, may be stored in the storage unit 25 in advance. .

  In FIG. 8, stores 1a, 1b,... Are adopted as unit objects, but other unit objects can be designated by the staff at headquarters 3 in step S6 requesting the creation of a report.

  From the above, the staff of the headquarters 3 that receives the report can easily grasp the degree of penetration of the energy-saving operation rules for each time zone or each day of the week (more accurately, the number of unit objects and the amount of violations that tend to increase energy). Note that the analysis by time zone and day of the week is an example, and analysis by other units such as by month is also possible.

7h) History The report creation unit 22c also outputs a history graph of the compliance rate for each month as shown in FIG. 9 on the report.

  The six circles in the two-dimensional plane of FIG. 9 correspond to each month in the 6 month analysis period. The numerical value in the circle represents the compliance rate for the corresponding month, and the position in the vertical axis direction of the circle represents the deviation from the average of the violation amount in the corresponding month. The position of the direction position represents the average amount of violation in the corresponding month.

  Based on the above, the staff of Headquarters 3 who receive the report over time of the degree of penetration of energy-saving operation rules (more precisely, the compliance rate, the deviation from the average of violations, and the average of violations) during a specific analysis period Can be easily grasped. Note that the analysis is performed on a monthly basis, and the analysis can be performed in other units such as weekly, daily, and hourly.

<Modification>
(1)
In the above embodiment, the energy-saving activity for the air conditioning facilities 50a, 50b,... Is analyzed. However, the system 100 is analyzed for the energy-saving activity for other equipment such as lighting equipment. It can also be applied to.

(2)
In the above embodiment, stores 1a, 1b,... Unit, department unit, and indoor unit 52 unit are adopted as units for measuring the violation amount. However, other units, for example, regional units, building type units, business form types (for example, distinguished by business hours, business contents, etc.) units, area level units, installation zone types (passenger seats, kitchens, etc.) units, allocation The operation schedule unit currently used may be employ | adopted. In order to calculate the violation amount or the like in another unit, it is necessary to hold information indicating the relationship between the unit and the indoor unit 52.

  By arbitrarily setting the unit object, the present invention can be applied to business models other than those described above. For example, it can also be used when a company that provides energy-saving services analyzes energy-saving activities for equipment that belongs to an independent client.

(3)
In the above embodiment, the report is generated by the remote management server 20 at the request from the management terminal 30, that is, at an arbitrary timing desired by the staff of the headquarters 3. However, the report is generated periodically. Alternatively, it may be created at both timings. The manner of providing the report is not limited to that via the Internet 6, but may be provided by FAX, mail, or other means.

(4)
The violation amount may be calculated by the controllers 10a, 10b,... And then transmitted to the remote management server 20. Alternatively, the operation history of the air conditioning equipment 50a, 50b,... Sent from the controllers 10a, 10b,... Is not calculated by the controllers 10a, 10b,. It may be calculated by the remote management server 20 based on the above.

(5)
In the above embodiment, the operation schedule is downloaded from the remote management server 20 to the controllers 10a, 10b,..., But the controllers 10a, 10b,. -It may be set directly to.

(6)
In the above embodiment, the original data of the report such as the amount of violation and the number of monitoring targets, and various items included in the report are calculated when the report is created. However, some or all of these values may be periodically calculated by the remote management server 20 and stored in a database in the storage unit 25. In this case, after the report delivery command (step S6) is issued, the time until the report is actually created is shortened.

(7)
In the above embodiment, the operation schedule can be different for each store 1a, 1b,..., And for each indoor unit 52 in the same store 1a, 1b,. It is also possible to apply the same operation schedule to the entire stores 1a, 1b,... Or to apply the same operation schedule to the indoor units 52 in the same stores 1a, 1b,.

(8)
What is output on the report may be a distribution table instead of a distribution graph.

(9)
In the above embodiment, the compliance rate is calculated as the ratio of the unit target on the energy saving side, but may be calculated as the ratio (deviation rate) of the unit target on the energy saving side.

(10)
In the above embodiment, as shown in the table of FIG. 7, an evaluation comment is derived only when there is a problem, but an evaluation comment is also derived when there is no problem. It may be.

(11)
In the above embodiment, the increased energy amount and the energy saving amount are calculated by detecting violation actions of the air conditioning equipment 50a, 50b,... Contrary to the operation schedule and converting the violation actions according to a predetermined rule. It has become. However, energy consumption is measured by installing a power meter or the like in the store 1a, 1b,..., And the amount of energy increase and energy saving is determined by the difference between the energy consumption and a predetermined threshold value. You may make it ask.

(12)
In the above-described embodiment, the controller 10a, 10b,... Is able to arbitrarily select store 1a, 1b,... Unit, department unit, or indoor unit 52 unit as a target unit for measuring the violation amount. The amount of increased energy and the amount of energy saving are calculated in units of 52 indoor units, which is the smallest unit. However, when the violation amount is measured only in the store 1a, 1b,..., The controller 10a, 10b,... Also calculates the amount of increased energy and the energy saving amount in the store 1a, 1b,. Good.

(13)
In addition to or instead of the method described above, the violation amount may be calculated based on only the increased energy amount or only the saved energy amount among the increased energy amount and the energy saving amount. In such a case, it is not necessary to consider the energy saving amount or the energy increase amount when calculating the violation amount, and the calculation load is reduced.

  FIG. 10A is a distribution graph when the violation amount is calculated only from the increased energy amount, and FIG. 10B is a distribution graph when the violation amount is calculated only from the energy saving amount.

  In such a modification, the following evaluation comments may be output on the report.

  When the vertex of the distribution graph in FIG. 10A is biased to the left, “there is less use of the air conditioner that increases the energy with respect to the operation schedule”, but when the vertex is biased to the right, “ Deviations in set temperature (too cold, too warm) or overuse of air conditioners overtime "are output as evaluation comments. In addition, when the distribution graph of FIG. 10A is uniformly distributed, “the unit objects that deviate from the operation schedule exist evenly with respect to the violation time” are partially concentrated. If it is, the evaluation comment “does not violate the driving schedule or is biased to violate” is output.

  On the other hand, when the top of the distribution graph in FIG. 10B is biased to the left, “there are many stores that operate the air conditioners according to the driving schedule”, “There is a possibility that there are many stores where a deviation of the set temperature (not cold or warm) or forgetting to turn off the air conditioner” occurs as an evaluation comment. Further, when the distribution graph of FIG. 10B is uniformly distributed, “unit objects that deviate from the operation schedule are present evenly with respect to the violation time” are distributed in a partly concentrated manner. If it is, the evaluation comment “does not violate the driving schedule or is biased to violate” is output.

(14)
In addition to or instead of the compliance rate, the absolute number of violation targets derived in the process of calculating the compliance rate may be output.

  The present invention has an effect that the degree of penetration of energy-saving operation rules with respect to all of a plurality of management points can be easily grasped in an organization that supervises the plurality of management points, and each of the plurality of one or more equipment devices. It is useful as a device management system that manages and manages all of the management points and a device management program that causes a computer to operate as a management system.
