  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, a power control system having a power management apparatus according to an embodiment of the present invention will be described. FIG. 1 is a communication system configuration diagram showing a schematic configuration of a power control system according to the present embodiment.

  As illustrated in FIG. 1, the power control system 10 includes the Internet 11, a plurality of first power management devices 12, a plurality of user terminals 13, and a second power management device 14.

  The Internet 11 connects a plurality of first power management apparatuses 12, a plurality of user terminals 13, and a second power management apparatus 14, and communicates signals such as information and control instructions. Note that a LAN (Local Area Network) 15 is constructed for each facility such as a plurality of stores, for example, and at least one first power management apparatus 12 and at least one user terminal 13 exist in each LAN 15. In the present embodiment, the first power management device 12 and the user terminal 13 existing in the same LAN 15 communicate via the second power management device 14. However, the first power management apparatus 12 and the user terminal 13 in the same LAN 15 may communicate directly.

  The first power management apparatus 12 is, for example, an EMS Gateway. The first power management apparatus 12 acquires demand power received from a commercial system in a facility to which the first power management apparatus 12 belongs from a power meter. The demand power is the accumulated power consumption in the demand time period. The demand time limit is a reference time used for a contract power agreement between a business operator operating a store and the power company. The first power management apparatus 12 periodically transmits the acquired demand power to the second power management apparatus 14. Further, the first power management apparatus 12 acquires a control instruction for a load device existing in the same LAN 15 from the second power management apparatus 14 by polling. Further, the first power management apparatus 12 can control load devices existing in the same LAN 15 based on the control instruction.

  The user terminal 13 is, for example, a PC, a tablet terminal, a smartphone, or the like, and has a display unit. The user terminal 13 issues an instruction for creating integrated work process chart information described later. Further, the user terminal 13 issues a control instruction for a load device existing in the same facility. The generation of the creation instruction and the control instruction is based on detection of a user operation on the device control page configured by the web browser. The user terminal 13 transmits the issued creation instruction and control instruction to the second power management apparatus 14. The user terminal 13 acquires integrated work process chart information in the facility where the same LAN 15 is provided from the second power management apparatus 14. The user terminal 13 can display the integrated work process chart on the display unit based on the acquired integrated work process chart information. In addition, the user terminal 13 can display the measured values measured by the sensors existing in the same LAN 15 and the operating state of the load device existing in the same LAN 15. When the user terminal 13 displays these pieces of information, the second power management apparatus 14 acquires data by HTTP, and the web browser of the user terminal 13 forms a page.

  The second power management apparatus 14 is, for example, an EMS (Energy Management System) server. The second power management device 14 receives the demand power transmitted from the first power management device 12 and stores it in its own memory 16. In addition, the second power management apparatus 14 receives a creation instruction and a control instruction issued by the user terminal 13. The second power management apparatus 14 creates integrated work process chart information based on the user terminal 13 creation instruction. In addition, the second power management apparatus 14 creates a control instruction for each load device. The user terminal 13 reads the created integrated work process schedule information. In addition, each first power management apparatus 12 acquires the received control instruction or the created control instruction by polling.

  Next, the creation of integrated work process chart information by the second power management apparatus 14 and the integrated work process chart information in the user terminal 13 will be described.

  The user terminal 13 can detect an operation for requesting creation of the integrated work process chart as well as designating a date for requesting creation. When the user terminal 13 detects an operation for requesting designation and creation of a date, the user terminal 13 issues a creation instruction and transmits it to the second power management apparatus 14.

  When the second power management apparatus 14 receives the creation instruction, the second power management apparatus 14 reads, from the memory 16, the normal power consumption prediction of the facility where the user terminal 13 exists on the specified date. The power consumption prediction is a predicted value of demand power at the end of the demand time period for each demand time period in a state where work processes and events described later are not performed. In the power consumption prediction, for example, a predicted value estimated in advance based on the scale of the facility and the type of load device is calculated in advance and stored in the memory 16. The second power management apparatus 14 updates the power consumption prediction stored in the memory 16 using the actual value of demand power acquired from the first power management apparatus 12. The actual value of demand power is generally the same from Monday to Friday, and is generally the same on Saturday and Sunday. Therefore, both power consumption prediction pre-calculation and power consumption prediction update are performed for each day of the week, particularly for weekdays and weekends.

  In addition, when the second power management apparatus 14 receives the creation instruction, the second power management apparatus 14 reads the registered personnel name from the memory 16 on the designated date. As will be described later, the personnel name is registered based on a user operation on the user terminal 13, and is not registered when a new integrated work process chart is created.

  In addition, when the second power management apparatus 14 receives the creation instruction, the second power management apparatus 14 reads the work process registered on the specified date from the memory 16 according to the read personnel name. The work process is a specific work process performed by personnel in the facility, such as cooking, item preparation, replenishment, ordering, and the like. In addition, the second power management apparatus 14 reads the event registered on the specified date from the memory 16. An event is an event that occurs simultaneously for a plurality of personnel in a facility, such as the entire morning meeting and the entire end party. As will be described later, the work process and the event are registered based on a user operation on the user terminal 13, and are not registered when a new integrated work process table is created.

  In work processes and events, demand power increases or decreases by execution. For example, during cooking of sugar beet, power is consumed by a fryer or the like, and during product supply and replenishment, power is consumed to maintain the temperature by opening a refrigerator or a warmer. On the other hand, in the whole morning meeting or the like, work required for normal facility operation such as cash registering becomes unnecessary, so that power consumption is reduced. For work processes and events that can change demand power, the amount of change in demand power is calculated in advance and stored in the memory 16 of the second power management device 14. When the second power management apparatus 14 reads the work process and event registered on the designated date, the second power management apparatus 14 also reads the amount of change in demand power for the read work process and event from the memory 16.

  The second power management apparatus 14 creates integrated work process chart information corresponding to the integrated work process chart IT as shown in FIG. 2 based on the read power consumption prediction, personnel names, work processes, and events. The integrated work process chart IT shown in FIG. 2 is an integrated work process chart that is newly displayed, for example, and does not display any personnel names, work processes, or events.

  The integrated work process chart IT includes a work process chart showing the work process scheduled to be executed and the execution time for each person. In the integrated work process table IT, the uppermost column indicates a period from 7:00 to 23:00, and the leftmost column indicates a registered person name. In the integrated work process chart IT, the background of the work process chart is color-coded according to the magnitude of the predicted value of demand power, so that the power consumption prediction is displayed together with the work process chart and the time axis aligned. A plurality of threshold values are stored in the memory 16 of the second power management apparatus 14 for color coding of predicted demand power values, and are read out for color coding.

  For example, in the present embodiment, the first threshold value and the second threshold value are determined in advance for color coding. The second power management apparatus 14 colors the background of the demand time period in which the predicted value of demand power is less than the first threshold value (see reference sign “G”). The second power management apparatus 14 colors the background of the demand time period in which the predicted value of demand power is greater than or equal to the first threshold value and less than the second threshold value (see reference sign “O”). The second power management apparatus 14 colors the background of the demand time period in which the predicted value of demand power is equal to or greater than the second threshold value (see reference sign “R”).

  The user terminal 13 reads the integrated work process table information created by the second power management apparatus 14 and displays the integrated work process table IT on the display unit. In the user terminal 13, on the displayed integrated work process table IT, an arbitrary work name, an arbitrary work process for an arbitrary demand period (first period), and an arbitrary demand period (second period). An input for registering an arbitrary event can be detected.

  When detecting an input for registering an arbitrary personnel name, the user terminal 13 displays the registered personnel name in the leftmost column of the integrated work schedule IT (see FIG. 3), and further displays the name of the personnel whose input has been detected. To the second power management apparatus 14. When the user terminal 13 detects an input for registering an arbitrary work process and an arbitrary event with respect to an arbitrary demand time period, the user terminal 13 combines the work process and event for which the input has been detected with the demand time period to the second power management apparatus 14. Send.

  When the second power management apparatus 14 receives any of the registered personnel name, work process, and event, it stores it in its own memory 16. Further, the second power management apparatus 14 reads the amount of change in demand power due to the work process and the event, together with the personnel name, work process, and event registered on the designated date. Further, the second power management apparatus 14 corrects the normal power consumption prediction based on the read amount of change in demand power. For example, in a demand time period with registration for executing an arbitrary work process, when the predicted value of normal demand power is akW and the amount of change due to the work process is bkW, the corrected predicted value is (a + b) Correct to kW. The second power management apparatus 14 reflects the corrected power consumption prediction on the integrated work process chart information.

  The user terminal 13 reads the integrated work process table information created again by the second power management apparatus 14 and displays the integrated work process table IT on the display unit. In the example of FIG. 4, the predicted value of demand power in the demand period from 9:00 to 9:30 and the demand period from 17:30 to 18:00 is greater than or equal to the first threshold and less than the second threshold, depending on the registered work process. Thus, the background of the demand time period changes from green to orange. In addition, the predicted value of demand power in the demand time period from 18:00 to 18:30 becomes equal to or greater than the second threshold, and the background of the demand time period changes from orange to red.

  When the personnel name, work process, and event are registered for the integrated work process schedule IT of a specific date, the registered work name, work process, and event are displayed when the integrated work process schedule IT of the date is subsequently displayed. Is shown.

  In the integrated work process chart IT described above, power consumption prediction is displayed, but it is also possible to display demand power consumption results. For example, when displaying the integrated work process schedule IT dated before today, the second power management apparatus 14 acquires the actual value of demand power in the demand time period before the present time. Therefore, the second power management apparatus 14 performs color coding on the actual value of demand power in the same manner as the predicted value of demand power, and has a higher density than the predicted value, that is, dark green, dark orange, and dark. Display in red. Further, the current demand time period is displayed differently from other demand time periods by a method such as blinking. Regarding the current demand time-based color coding, the second power management device 14 determines the color coding for each demand power measurement, for example, every minute, and displays integrated work process chart information, that is, the displayed integrated work process chart IT. To reflect.

  Next, the creation process executed by the second power management apparatus 14 in the present embodiment will be described with reference to the flowchart of FIG. The second power management apparatus 14 starts the creation process when receiving an instruction for creating the integrated work process chart information from the user terminal 13 together with the designation of the date.

  In step S <b> 100, the second power management apparatus 14 reads the normal power consumption prediction for the designated date, that is, the normal demand power prediction value for each demand time period from the memory 16. When the power consumption prediction is read, the process proceeds to step S101.

  In step S101, the second power management apparatus 14 reads the registered personnel name, work process, and event (see “registration information” in FIG. 4) from the memory 16 on the specified date. When the registration information is read, the process proceeds to step S102.

  In step S102, the second power management apparatus 14 corrects the power consumption prediction based on the normal power consumption prediction read in step S100 and the work process and event read in step S101. Further, the second power management apparatus 14 colors the corrected power consumption prediction for each demand period. If color coding is performed, the process proceeds to step S103.

  In step S103, the second power management apparatus 14 creates integrated work process table information based on the registration information read in step S101, the power consumption prediction corrected in step S102, and the color classification of the power consumption prediction. When the integrated work process chart information is created, the creation process is terminated.

  Next, update processing executed by the second power management apparatus 14 in the present embodiment will be described with reference to the flowchart of FIG. The second power management apparatus 14 starts the update process when receiving at least one of a staff name, a work process, and an event from the user terminal 13 displaying the integrated work process table.

  In step S <b> 200, the second power management apparatus 14 registers the personnel name, work process, and event received from the user terminal 13 on the designated date and stores them in the memory 16. When registration information such as a staff name is stored, integrated work process chart information is created by executing the same processes as steps S100 to S103 in the creation process in steps S201 to S204. When the integrated work process chart information is created, the update process is terminated.

  According to the power management apparatus of the present embodiment configured as described above, it is possible to create an integrated work process chart IT that displays the work process chart on the user terminal 13 together with the power consumption prediction in the same facility. Since the power consumption prediction is displayed together with the work process table, it is possible to create a work process so that the demand power is suppressed to less than the first threshold value or the second threshold value for each demand time period.

  Also, according to the power management apparatus of the present embodiment, the work process table and the power consumption prediction time axis are displayed together, so that it is easy to recognize when the work process may be specified and when to avoid it. Become.

  Further, according to the power management apparatus of the present embodiment, the period in which the power consumption prediction exceeds the threshold value is displayed in a manner that can be distinguished from other periods in units of demand time period, so the time when designation of the work process should be avoided It is possible to call attention to the user.

  Further, according to the power management apparatus of the present embodiment, since the work process and the event for which the execution time is specified are displayed on the integrated work process table, the user can easily grasp the time when the work process and the event should be executed. .

  Further, according to the power management apparatus of the present embodiment, since the power consumption prediction to be displayed is updated based on the work process and the event for which the execution time is specified, the power consumption is less than the threshold value by executing the arbitrary work process and the event. It is possible to easily recognize whether or not it can be suppressed.

  Further, according to the power management apparatus of the present embodiment, the normal power consumption prediction can be changed according to the day of the week, so that the prediction accuracy of power consumption prediction can be improved when a store or the like is used as a facility.

  Moreover, according to the power management apparatus of this embodiment, since normal power consumption prediction is created and updated based on actual power consumption, the prediction accuracy can be improved as the use continues.

  Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various changes and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention.

  For example, in the present embodiment, the second power management device 14 is configured to create integrated work process chart information, but the first power management apparatus 12 may be configured to create an integrated work process chart. Moreover, the structure which installs a power management program in the normal 1st power management apparatus 12, and produces an option may be sufficient. In the present embodiment, the background of the work process chart is configured to display the power consumption prediction by color-coding according to the magnitude of the predicted value of demand power, but using graphs such as a line graph and a bar graph A power consumption prediction may be displayed.
