Description

  The present invention relates to an energy management apparatus that manages energy consumption by an equipment monitoring device that monitors the energy consumption of equipment.

  In recent years, it has been proposed to monitor energy consumption by facility equipment and perform management to further suppress the energy consumption. An energy management apparatus is for performing the management, and a conventional energy management apparatus is disclosed in, for example, Patent Document 1.

The conventional energy management device described in Patent Document 1 is connected to a facility equipment monitoring device that monitors the energy consumption of the facility equipment via a communication network, and the cumulative energy consumption (one day) from the equipment monitoring device. (Accumulated value of energy consumption) is received every predetermined time. Thereby, the energy consumption of the equipment is managed along the target pattern (data) indicating the target accumulated energy consumption for each predetermined time via the equipment monitoring device. With this management, the actual accumulated energy consumption can be further suppressed.
Japanese Patent No. 3839440

  Management of energy consumption according to the target pattern by the conventional energy management device described in Patent Document 1 described above sets an alarm line (alarm value line) in which the target pattern is increased by a predetermined rate, and accumulates energy consumption. It was done by operating to reduce energy consumption when the amount exceeded the alarm line. However, in such management, the energy consumption is forcibly suppressed in a situation where the energy consumption of the entire equipment is large. This is because if the actual energy consumption per unit time is not larger than the energy consumption assumed in the target pattern, the accumulated energy consumption will not exceed the alarm line. For this reason, there has been a problem that the amount of energy actually required by the equipment cannot always be supplied (secured).

  Some equipment may always consume energy, such as a refrigerator or a freezer. Management that assumes an alarm line cannot reliably supply the necessary energy to such equipment.

  For example, in the side dish department that produces and sells supermarket side dishes, the line-up of goods is completed by noon due to requests from the store assortment and actual sales trends, and the addition and replenishment of necessary items for the evening. A production plan is made. In reality, however, production operations depend on employees and sales depend on customers. For this reason, in the production of sugar beet whose taste changes over time, it is indispensable to respond according to the situation. Depending on the situation, the actually required cumulative energy consumption may temporarily exceed the alarm line set from the target pattern temporarily. Management that assumes an alarm line cannot respond appropriately to such cases.

  For this reason, in order to properly manage the energy consumption of the equipment, it is also important to consider the type of equipment to be managed and how the equipment is used.

  An object of this invention is to provide the technique for managing the energy consumption of an installation apparatus more appropriately.

The energy management device of the present invention is based on the premise that the energy consumption is managed by the equipment monitoring device that monitors the energy consumption of the equipment, and the actual energy of the equipment obtained by the monitoring by the equipment monitoring device. Consumption acquisition means for acquiring consumption data indicating consumption, pattern storage means for storing target pattern data indicating target energy consumption, which is a target energy consumption in a fixed time unit, and consumption acquisition In accordance with the energy consumption indicated by the consumption data acquired by the means, the target energy consumption to be corrected is selected from the target energy consumption indicated by the target pattern data stored in the pattern storage means at regular intervals. Pattern correction means for generating correction target pattern data by correction, and pattern storage means Consumption control means for managing the energy consumption of the equipment via the equipment monitoring device using one of the stored target pattern data and the correction target pattern data generated by the pattern correction means; And the target energy consumption indicated by the target pattern data at regular intervals is a target value set for the energy consumed transiently by the equipment, and the consumption management means consumes transiently. and the amount of energy to the target, to manage the energy consumption of the equipment.

  In addition, the said pattern correction means WHEREIN: When the management division which is a predetermined time range is set, the target pattern data according to the energy consumption which the consumption data which the consumption acquisition means acquired for every management division shows It is desirable to make corrections. When the upper limit value of the target energy consumption is set, it is desirable to select the target energy consumption to be corrected from the target energy consumption that does not exceed the upper limit by the correction.

Further, pattern correction means, if the existing modified target pattern data is present, depending on the energy consumption consumption acquiring unit has acquired, make corrections targeting the modified target pattern data, another modified target pattern It is desirable to generate data.

The pattern correction apparatus according to the present invention is prepared for managing the energy consumption of equipment, and corrects target pattern data indicating a target energy consumption, which is a target energy consumption, with a fixed time as a unit. Based on the premise, the consumption acquisition means for acquiring consumption data indicating the actual energy consumption of the equipment obtained by the equipment monitoring apparatus for monitoring the energy consumption of the equipment, and the consumption acquisition means According to the energy consumption indicated by the consumption data, the target pattern data is corrected by selecting and changing the target energy consumption to be changed from among the target energy consumption indicated by the target pattern data at regular intervals. comprising a pattern modification means for the target energy consumption target pattern data indicates a predetermined time as a unit Is Ru target der set for the amount of energy transiently consumed by equipment.

The program of the present invention is a computer that can be used as an energy management device that manages energy consumption by the equipment monitoring device that monitors the energy consumption of the equipment, and the equipment obtained by monitoring by the equipment monitoring device. The target pattern data stored in the storage device according to the consumption acquisition function for acquiring consumption data indicating the actual energy consumption of the device and the energy consumption indicated by the consumption data acquired by the consumption acquisition means A pattern correction function for generating corrected target pattern data by selecting and correcting a target energy consumption to be corrected from among target energy consumptions indicated by a unit of time, a target pattern data, and a pattern correction function Using one of the generated modified target pattern data, A consumption management functions via a vessel monitoring apparatus for managing energy consumption of the equipment, to achieve the target energy consumption target pattern data is shown in every fixed time, the amount of energy transiently consumed by equipment The consumption amount management function manages the energy consumption amount of the equipment for the transient energy consumption amount .

  In the present invention, the target pattern data indicating the target energy consumption, which is a target energy consumption, is prepared for managing the energy consumption of the equipment, and the energy consumption is monitored in units of a fixed time. The target energy consumption to be changed in the target energy consumption indicated by the target pattern data at regular intervals according to consumption data indicating the actual energy consumption of the equipment obtained by the equipment monitoring device. Modify by selecting and changing.

  By making such a correction, even if the actual energy consumption exceeds the target energy consumption, it is possible to avoid the energy consumption immediately with a high probability. As a whole, an increase in energy consumption can be avoided, and when a large amount of energy is needed temporarily, the amount of energy can be secured with a high probability. For this reason, the energy consumption of the equipment is managed more appropriately. In particular, the energy consumption can be managed in a form that matches the usage state of the equipment (the actual work in the production of the product, etc.).

  If the target energy consumption indicated by the target pattern data at regular intervals is the target value set for the energy consumed transiently by the equipment, the energy that the equipment consumes regularly The amount can be reliably secured (supplied). Therefore, the energy consumption of the equipment can be managed more appropriately.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a network system constructed using the energy management apparatus according to the present embodiment. The energy management device (hereinafter abbreviated as “management device”) 1 is connected to a plurality of facility equipment monitoring devices 3 via a communication network 2.

  Each equipment monitoring device 3 monitors and controls the energy consumption of one or more equipment (not shown), and includes equipment equipment measuring unit 31 and communication unit 32. The equipment device measuring unit 31 measures the amount of energy actually consumed by the equipment device, for example, every predetermined time, and the measurement result is transmitted to the management apparatus 1 by the communication unit 32 via the communication network.

  Before describing the management apparatus 1, the energy management method in the present embodiment will be specifically described with reference to FIGS. The management method assumes energy management of facility equipment for producing a product in which the amount of energy required varies depending on the situation, for example, in a supermarket side dish section.

  FIG. 3 is a diagram for explaining energy consumption that is an object of energy management in the present embodiment. Fig. 3 (a) is a graph showing the (actual) energy consumption by all the equipments in one day every hour (unit time), and Fig. 3 (b) is a transient (in the situation) FIG. 4 is a graph showing (actually) the amount of energy consumed (actually) every hour (unit time). In both FIG. 3A and FIG. 3B, the vertical axis represents energy consumption, and the horizontal axis represents time (time).

  As shown in FIG. 3A, the energy consumption is constantly consumed even outside the work time (hereinafter referred to as “overtime steady consumption”), and the amount consumed regularly within the work time ( Hereinafter, it can be broadly divided into “constant consumption within time”) and the amount consumed transiently within the working time (hereinafter referred to as “transient consumption within time”).

Regardless of whether or not it is outside the working hours, the above-mentioned steady consumption overtime corresponds to the minimum amount of energy required. As the equipment that generates the consumption, for example, a device that is always turned on, such as a refrigerator or a freezer.

  The above-mentioned steady consumption amount in time corresponds to the minimum amount of energy required within the working time. As the equipment that generates the consumption, for example, an equipment that is always turned on during the working time, such as an exhaust fan, corresponds. The in-time transient consumption corresponds to the energy consumption generated by the equipment used as necessary within the working time. As the equipment, for example, an electric cooking device such as a microwave oven corresponds.

  In FIG. 3A, the steady consumption outside time and the steady consumption within time are always constant regardless of the time. However, they usually vary to some extent with time. This is because, for example, refrigerators and freezers are normally opened and closed frequently during work hours. Such fluctuations are ignored to avoid confusion.

  Among the above-mentioned consumption amounts, the regular consumption amount outside the hour and the regular consumption amount within the hour are the minimum amount of energy necessary for performing work. For this reason, in this embodiment, energy management is performed only for the in-time transient consumption shown in FIG. This ensures (supply) the minimum amount of energy required.

  FIG. 4A is a diagram illustrating a method for correcting a target value when the actual value of energy consumption per hour falls below the target value, and FIG. 4B is a diagram illustrating the cumulative value of the target value and the actual value. It is. 4A and 4B, the vertical axis represents energy consumption, and the horizontal axis represents time (time). In FIG. 4A, the actual value is indicated by a hatched frame (bar graph), and the target value is indicated by a simple frame (bar graph). In FIG. 4B, the actual value (cumulative value) is indicated by a thick line (line graph) and a hatched frame (bar graph), and the target value (cumulative value) is a thin line (line graph) and a simple frame (bar graph). Is shown. The same applies to FIGS. 5A and 5B.

  A broken line and a solid line parallel to the horizontal axis in FIG. 4A are shown at intervals of one unit determined by energy consumption. The solid line indicates the upper limit value per hour (unit time corresponding to a fixed time) of the energy consumption as the target value. The energy consumption per unit is, for example, 10 kWh. The unit is hereinafter referred to as “consumption unit”.

  The upper limit value is set from past data or simulation. In the present embodiment, as shown in FIG. 7, the value indicates the energy consumption in the above consumption unit. Management of energy consumption is performed in units of consumption.

  The target value of energy consumption shown in FIG. 4A is obtained by setting the in-time transient consumption shown in FIG. 3B as a target value. The target value is set for each unit time (here, one hour) in a table format, for example, as shown in FIG. The target value set in the table format corresponds to the target pattern data.

  The “management category” shown in FIGS. 4A and 4B corresponds to a time range in which energy consumption is managed independently. Since the boundary is 14 o'clock, the energy consumption management here is performed separately for the time zone of 0-14 o'clock and the time zone of 14-24 o'clock.

As is clear from FIGS. 4A and 4B, the in-time transient consumption is 0 consumption unit in the time zone from 15:00 to 15:00. This is because production is scheduled not to be performed due to a break between 13 and 15 o'clock, and subsequent production planning. For this reason, the boundary of the management division is set at 14:00 between 13:00 and 15:00, and the energy consumption is managed for each management division. The management division can be set in a table format as shown in FIG. 8, for example.

  When energy consumption is managed for each management category, it is avoided that management in one management category affects another management category. By avoiding this, even if the amount of energy is temporarily consumed in a form different from the target pattern data, the range for performing management according to such consumption is localized. As a result, appropriate management can be performed while suppressing complexity.

  For example, the energy consumption per unit time is different even though the cumulative energy consumption (cumulative value) over a certain time zone is almost the same as that of the target pattern data due to the variation in sales of products. There may be situations. Moreover, energy consumption may fluctuate by the malfunction which generate | occur | produced in a certain installation apparatus. More specifically, there is a case where the product cannot be produced while there is a defect in a certain equipment and the energy consumption is reduced, and after the defect is resolved, the energy consumption is increased to expedite the production of the product. is there. Such a case can be appropriately handled by local management (in a relatively short time range).

  In the example shown in FIG. 4A, the actual value of energy consumption is 1 consumption unit in the time zone from 7 to 8 o'clock, 2 consumption units in the time zone from 8 to 9 o'clock, and 2 consumption units in the time zone from 9 to 10 o'clock. It has become. Thereby, the actual value is less than the target value by one consumption unit for 2 hours from 8 to 10 o'clock. For this reason, the target value for the time zone from 11 to 12 o'clock is corrected from 2 consumption units to 3 consumption units, and the target value for the time zone from 12 to 13 o'clock is corrected from 1 consumption unit to 2 consumption units.

  In this way, as shown in FIG. 4B, while the cumulative value of the actual value is restricted so as not to exceed the cumulative value of the target value, the amount of time that the actual value per hour has fallen below the target value is reduced. The original target pattern data is corrected by assigning it in a form that is added in another time zone, that is, by moving the portion below it later. When the target pattern data corrected in this way (corrected target pattern data) is generated, the energy consumption is managed using the generated target pattern data.

  Corrected target pattern data is generated at any time according to the amount of energy actually consumed per unit time, and valid pattern data, that is, pattern data used for actual management is changed from the target pattern data to the corrected target pattern data, or corrected. The target pattern data is changed to another corrected target pattern data. Accordingly, in the cases shown in FIGS. 4A and 4B, the correction target pattern data is generated at 9:00 and 10:00. Since the corrected target pattern data is sequentially generated as necessary in this way, the valid pattern data is hereinafter referred to as “effective target pattern data”.

  FIG. 5A is a diagram for explaining a method for correcting a target value when the actual value of energy consumption per hour exceeds the target value, and FIG. 5B is a diagram showing the cumulative value of the target value and the actual value. It is. Next, with reference to FIG. 5A and FIG. 5B, a method for correcting the target value in that case will be specifically described. Here, it is assumed that the target value of energy consumption per hour, that is, the target pattern data is the same as that shown in FIG. 4A and no upper limit value is set.

  As shown in FIG. 5A, an energy amount of 4 consumption units exceeding the target value of 3 consumption units is consumed in the time zone from 8 to 9 o'clock. For this reason, after the fact becomes clear, the target value of the time zone from 13:00 to 13:00 is corrected from 1 consumption unit to 0 consumption unit. After it becomes clear that the energy consumption of 4 consumption units exceeding the target value of 3 consumption units was consumed in the time zone of 9-10 o'clock, the target value of the time zone of 11-12 o'clock was 1 consumption from 2 consumption units The unit has been corrected.

  In this way, while limiting the cumulative value of the actual value so as not to exceed the cumulative value of the target value, the target of another time zone is increased by the amount of time that the actual value per hour exceeds the target value. The original target pattern data or the corrected target pattern data is corrected by assigning a value, that is, by moving forward the target value for the subsequent time zone if it exceeds the value. For this reason, as in the case where the actual value of the energy consumption per hour is lower than the target value, appropriate management can be performed while suppressing complication. Even if the actual value exceeds the target value, the amount of energy consumed is reduced in a time zone where it can be reduced, so that it is avoided immediately. But it can be managed in a way that suits the situation.

  As described above, the generation of the corrected target pattern data is performed every time it is determined that the actual value of unit time is different from the target value (determination based on the consumption unit). The generation itself is performed by correcting the effective target pattern data. Therefore, as shown in FIGS. 9A and 9B, the correction target pattern data is managed with the time (correction time) at which it is generated. A thick broken line in FIGS. 9A and 9B indicates a portion where the target value is corrected. Thereby, the upper side of the thick line coincides with the actual value.

Returning to the description of the management apparatus 1 shown in FIG.
The management apparatus 1 manages energy consumption as described above. As shown in FIG. 1, the communication unit 101, the actual value storage unit 102, the cumulative actual value storage unit 103, the display unit 104, and the determination Unit 105, management category setting unit 106, target value correction unit 107, target value setting unit 108, corrected target value storage unit 109, cumulative target value storage unit 110, and input / output unit 111. Each of these parts 101 to 111 is as follows.

  The communication unit 101 is for transmitting and receiving data to and from each equipment monitoring device 3 via the communication network 2. The actual value storage unit 102 is for storing the actual value (consumption data indicating the amount of energy actually consumed) received from the equipment monitoring device 3 via the communication unit 101. Here, for convenience of explanation, each equipment monitoring device 3 measures the actual value (energy consumption) of the unit time for each unit time (1 hour) in which the target value is set as the target pattern data. Suppose. The measured result value may be transmitted autonomously from each equipment monitoring device 3 side to the management device 1, but is transmitted by a request from the management device 1 side. That is, it is assumed that the management device 1 collects (acquires) the actual value of the immediately preceding unit time from each facility device monitoring device 3 at unit time intervals.

  The accumulated actual value storage unit 103 accumulates (accumulates) the actual values stored in the actual value storage unit 102, and totals all actual values up to the last stored actual value (FIG. 4B, FIG. 5B) is calculated and stored. The display unit 104 is for displaying an image on a display device (not shown), for example, and displays the accumulated value stored in the accumulated result value storage unit 103 as shown in FIG. 4A or 5B.

  As shown in FIG. 6, the target pattern data is obtained by setting a daily target value every hour. For this reason, data storage (storage) in the actual value storage unit 102 and the cumulative actual value storage unit 103 is performed separately for each day.

  The management category setting unit 106 is for setting the management category, and stores data indicating the time zone for each management category in a table format as shown in FIG. 8, for example. The target value setting unit 108 is a storage unit that stores target pattern data. As shown in FIG. 6, the target value is set for each unit time zone in a table format. The target value correcting unit 107 corrects the target pattern data stored in the target value setting unit 108, and the corrected target pattern data obtained by the correction is stored in the corrected target value storage unit 109.

  The target value correcting unit 107, when the corrected target pattern data already exists in the corrected target value storage unit 109, performs correction on the corrected target pattern data. Thereby, the corrected target pattern data is stored in the corrected target value storage unit 109 as shown in FIG. 9A or 9B, for example.

  In the present embodiment, the upper limit values shown in FIGS. 4A and 7 can be set. The upper limit value is stored in the management category setting unit 106 or the target value setting unit 108. Data is stored in the management category setting unit 106 and the target value setting unit 108 by the input / output unit 111. The input / output unit 111 stores data input or designated by the operation according to the operation of the user (operator) in the management category setting unit 106 or the target value setting unit 108.

  The accumulated target value storage unit 110 calculates and stores the accumulated value of the target value at each time (1 hour interval from 0 to 24:00) for each modified target pattern data stored in the modified target value storage unit 109. .

  The determination unit 105 refers to the data stored in the actual value storage unit 102, the cumulative actual value storage unit 103, the target value setting unit 108, the corrected target value storage unit 109, and the cumulative target value storage unit 110, respectively. It is determined whether or not the effective target pattern data (target pattern data or corrected target pattern data) should be corrected, and the target value correcting unit 107 is controlled according to the determination result. Accordingly, when it is determined that correction is necessary, necessary information is provided to the target value correction unit 107 and correction is instructed. As a result, the correction shown in FIG. 4A or 5A is performed. Specifically, the information provided to the target value correcting unit 107 is a difference between the actual value and the target value (a value expressed in consumption units).

  The determination unit 105 manages energy consumption via each facility device monitoring device 3. The management is performed according to the cumulative value of energy consumption (actual value), the cumulative value in the effective target pattern data, the energy consumption allowed in the target management category, the current time, and the like. Specifically, the control for reducing (suppressing) the energy consumption by the management is performed by, for example, the equipment monitoring apparatus 3 in which the cumulative value of the actual value is equal to or greater than the total cumulative value in the effective target pattern data. To the subject. As a result, the determination unit 105 instructs the facility equipment monitoring device 3 as an object via the communication unit 101 to reduce energy consumption so that the cumulative value exceeding the effective target pattern data is reduced.

  The instruction is that the cumulative value of the actual value exceeds the cumulative value at the current time of the effective target pattern data, and the difference between them (= the cumulative value of the actual value−the cumulative value of the effective target pattern data), The situation where the difference from the target value accumulated from the current time of the effective target pattern data to the boundary of the management category is less than or equal to the predetermined value, that is, the accumulated value unless the amount of energy consumed is forcibly suppressed May be performed on the equipment monitoring apparatus 3 that is expected to be more likely to exceed the effective target pattern data. In such a case, energy consumption can be suppressed so that the accumulated value does not exceed the effective target pattern data.

  The management device 1 includes the respective units 101 to 111 as described above. The pattern correction apparatus according to the present embodiment is realized by the units 101 to 103 and 105 to 110 excluding the display unit 104, for example. This is realized on the management apparatus 1. The realization may be performed on a device other than the management device 1 or may be realized as a dedicated device.

The management device 1 (and the pattern correction device) is a computer (with a CPU installed therein) that executes a program that has a function for realizing the units 101 to 111 described above. The effective target pattern data is corrected by the program by, for example, starting a subprogram constituting the program by an interrupt signal generated at an interval of one hour. Data stored in each of the units 102, 103, 106, and 108 to 110 is stored in, for example, an auxiliary storage device or a semiconductor memory. The computer includes a CPU, an auxiliary storage device, a semiconductor memory, a communication device for performing communication via the communication network 2, a display control device for displaying an image on the display device, a recording medium such as an optical disk, etc. A medium driving device for driving the computer, an input control device for detecting an operation on a keyboard and a pointing device, and the like.

  FIG. 2 is a flowchart of scheduled processing realized by executing the subprogram. The scheduled process is a process for collecting the actual value of unit time measured by the equipment monitoring device 3 and correcting the effective target pattern data to be corrected as necessary. Next, the scheduled process will be described in detail with reference to FIG. Here, for the sake of convenience, there is only one effective target pattern data to be corrected, that is, only one equipment monitoring device 3 that collects actual values.

  As described above, the energy consumption is managed for each management category. Accordingly, in the description of FIG. 2, the cumulative value of the actual value (indicated as “actual cumulative value in the section” in the figure) means the cumulative value in the current management category, and the cumulative value of the target value (in "Target cumulative value" means the total cumulative value in the management category.

  First, in step S <b> 1, the equipment device monitoring apparatus 3 is requested to transmit a result value via the communication unit 101 and is acquired. In subsequent step S2, the actual value and the target value are compared, and the magnitude relationship between them is determined. If they match within a range of, for example, less than 0.5 consumption units, it is determined that they are equal, and it is determined that the effective target pattern data does not need to be corrected.

  When the actual value is 0.5 unit of consumption or smaller than the target value, it is determined that the actual value is smaller than the target value, and the process proceeds to step S3, where the actual value accumulated value ("intra-zone actual accumulated value in the figure" ”) And the cumulative value of the target value (indicated as“ target cumulative value in the section ”in the figure), and the magnitude relationship between them is determined. If the cumulative value of the actual value (cumulative value in the current management category) is, for example, 0.5 consumption units or less, the cumulative value is smaller than that of the target value (total cumulative value in the current management category). The process proceeds to step S5, and if an upper limit value is set, the target value in a time zone that does not exceed the upper limit value is corrected later in a range not exceeding the total cumulative value of the management category (see FIG. 4A) After the correction target pattern data obtained by the correction is stored, the process proceeds to step S6. Otherwise, the cumulative value of the actual value is determined to be greater than the target value, and the process proceeds to step S4.

  In step S4, since the energy amount corresponding to the total cumulative value of the target value assigned to the current management category is consumed, an alarm for notifying that is output, for example, after outputting a message on the display device Then, the abnormality process of step SE1 is executed. This abnormal process is executed as a subroutine process different from the regular process, for example.

  On the other hand, in step S6, it is determined whether or not the boundary is a management division. If the boundary (0:00 or 14:00 in the example of FIG. 8) has arrived, the determination is YES, the process proceeds to step S4, the corrected target pattern data created in the immediately preceding step S5 is discarded, and the management category Is output as a warning that the change is made (shifted), and then the abnormality process of step SE1 is executed. Otherwise, the determination is no and the scheduled process is terminated here.

  The abnormality process is for performing management of energy consumption thereafter depending on the situation. By the abnormal processing, for example, allocation of excess amount of energy that is allowed to be consumed in the current management category, suppression of energy consumption, response to the next management category (migration), etc. automatically or by operator instruction It is realized by. Thereby, in the transition from step S6, setting of the total cumulative value of the target value, clearing of the cumulative value of the actual value, etc. are performed to prepare for management of energy consumption in the next management category. In the transition from step S3, the process for continuing the management of energy consumption in the current management category, the allocation of the excess energy amount that allows consumption, and the suppression of energy consumption through the equipment monitoring device 3 , Etc. will be performed as necessary. As described above, in the present embodiment, the energy consumption is suppressed when the correction target pattern data cannot be generated.

  If the actual value is 0.5 consumption units or more larger than the target value, it is determined in step S2 that the actual value is larger than the target value, and the process proceeds to step S7. In step S7, as in step S3, the cumulative value of the actual value is compared with the cumulative value of the target value (total cumulative value), and the magnitude relationship therebetween is determined. If the cumulative value of the actual value is smaller than, for example, 0.5 consumption units, the cumulative value is determined to be smaller than that of the target value, and the process proceeds to step S9. If the upper limit value is set, the cumulative value is exceeded. The target value is corrected ahead of schedule in a range that does not exceed the cumulative value of all the management categories of the initial target value (target pattern data) while considering that there is no correction (FIG. 5A), and the corrected target pattern obtained by the correction After storing the data, the process proceeds to step S10. Otherwise, the cumulative value of the actual value is determined to be greater than the target value, and the process proceeds to step S8.

  In step S8, since the energy amount corresponding to the total accumulated value of the target value assigned to the current management category is consumed, an alarm for notifying that is output, for example, after outputting a message on the display device Then, the abnormality process of step SE2 is executed. This abnormal process is executed as a subroutine process different from the regular process, for example, similarly to the abnormal process executed in step SE1.

  On the other hand, in step S10, it is determined whether or not the boundary is a management division. If the boundary (0 or 14:00 in the example of FIG. 8) has arrived, the determination is YES, the process proceeds to step S8, the correction target pattern data created in the immediately preceding step S9 is discarded, and the management category Is output as a warning, and then the abnormality process of step SE2 is executed. Otherwise, the determination is no and the scheduled process is terminated here.

  The abnormal process is for performing subsequent energy consumption management according to the situation, for example, as in the abnormal process of step SE1. By the abnormal processing, for example, allocation of excess amount of energy that is allowed to be consumed in the current management category, suppression of energy consumption, response to the next management category (migration), etc. automatically or by operator instruction It is realized by. Thereby, in the transition from step S10, setting of the total cumulative value of the target value, clearing of the cumulative value of the actual value, etc. are performed to prepare for the management of energy consumption in the next management category. In the transition from step S7, the process for continuing the management of the energy consumption in the current management category, the allocation of the excess of the amount of energy permitted to be consumed, and the suppression of the energy consumption through the equipment monitoring device 3 , Etc. will be performed as necessary.

  In the present embodiment, the response to the next management category associated with the arrival of the boundary of the management category is performed by executing the abnormal process in step SE1 or SE2, but the response is performed within the scheduled process. May be. Further, one or more functions realized by the abnormal process may be realized by the scheduled process.

In the present embodiment, the difference between the actual value and the target value is generated by changing the target value in one time zone, and the corrected target pattern data is generated. The target value of the belt may be changed. Also, change of actual values per unit time in the past is analyzed and one or more basic patterns are extracted and registered, and changes in actual values obtained at the present time from the registered patterns May be selected, and the effective target pattern data may be corrected along the selected pattern.
