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

  FIG. 1 is a block diagram showing an example of the configuration of a power management system 100 according to an embodiment of the present invention. As shown in FIG. 1, the power management system 100 includes a power management server 10, a store terminal 21, and electrical devices 21 a to 21 g connected to the store terminal 21. In FIG. 1, only the store terminal 21 installed in the store A and the electrical devices 21 a to 21 g connected to the store terminal 21 are disclosed, but the store terminals installed in one or more other stores, respectively. And an electric device connected to the store terminal. Moreover, although the electric equipments 21a-21g are illustrated in FIG. 1, what kind of thing may be sufficient if it is an apparatus which receives electric power supply and operate | moves.

  The power management server 10 and the store terminal 21 are each connected to a communication network 30 such as a LAN or the Internet. In addition, the electrical devices 21a to 21g are connected to the store terminal 21 via a communication network 40 such as a LAN or a wireless LAN.

  The power management server 10 is managed by a system administrator of the system 100 and is configured by an information processing apparatus such as a WWW server. Further, the store terminal 21 is managed by the store A and is configured by an information processing device such as a personal computer.

  The power management server 10 executes various processes for stopping power supply to the electrical devices installed in each store in an emergency. The power management server 10 also includes a power management master DB 11 that stores a power management master described later, an electrical equipment operation information DB 12 that stores electrical equipment operation information described later, and a stop continuation that stores stop continuation allowable time information described later. And an allowable time information DB 13. The power management master DB 11, the electrical equipment operation information DB 12, and the stop continuation allowable time information DB 13 may be inside or outside the power management server 10.

  FIG. 2 is an explanatory diagram illustrating an example of a power management master. As shown in FIG. 2, in the power management master, electric device information in which an ID (electric device ID) of a controllable electric device installed in each store is associated with a name of the electric device is registered. Has been. In addition, as shown in FIG. 2, the power management master is set with electrical equipment information of electrical equipment installed in each store for each store, and for each emergency level (in this example, levels 1 to 3). In step 3), electric device information of the electric device whose power supply is to be stopped is set.

  An electric device that does not interfere with store sales even if power supply is stopped is associated with a lower emergency level. In this example, three levels of emergency levels are set, and an electrical device that does not interfere with store sales even if power supply is stopped is associated with level 1 of the lowest level. In addition, an electrical device that has a problem that the store operation is hindered when the power supply is stopped but that can continue the operation is associated with the intermediate level 2. And the electric equipment which shows the trouble of the grade which cannot continue a shop business when electric power supply is stopped is matched with level 3 of the highest level. The level associated with each electrical device is determined in advance by a system administrator or the like, and a power management master is set according to this determination.

  In this example, the emergency level has three levels, but may be two levels or four or more levels. Moreover, in FIG. 2, the level with which each electric equipment is matched is an example, and may be matched with another level.

  Here, the “emergency level” is the ratio of the power used to the total power supplied in the target area (for example, the area under the jurisdiction of the power company that supplies power to the area where the store is located: specifically Hokkaido, for example). This means a level that indicates the urgency of the response when it is necessary to reduce the amount of power used due to the increase in the power consumption. Therefore, for example, when the ratio of the used power to the supplied power of the entire target area is extremely high (for example, 98%), it is necessary to quickly and drastically reduce the power usage, so the emergency level is the highest level. Become. For example, when the ratio of the used power to the supplied power of the entire target area is higher than a predetermined threshold (for example, 90%), it is necessary to reduce the power usage amount just in case, so the emergency level is the lowest level. Become. In this example, for example, when the ratio of the used power to the supplied power of the entire target area becomes 90%, it is judged as level 1, when it becomes 95%, it is judged as level 2, and when it becomes 98%, it is judged as level 3. And This determination may be made by an administrator who manages the power management server 10, or a notification from the server device managed by the power company (notification of the ratio of the used power to the supplied power in the entire target area). The received power management server 10 may determine automatically.

  FIG. 3 is an explanatory diagram illustrating an example of the electrical equipment operation information. The electrical device operation information is information in which the name of the electrical device, the power source type used, the number of the electrical devices, the number of electrical devices in operation, and the power consumption are associated with each type of electrical device. It is. The power supply type used includes single-phase and three-phase.

  FIG. 4 is an explanatory diagram illustrating an example of stop continuation allowable time information. The stop continuation allowable time information is information in which the stop continuation allowable time indicating the allowable time for allowing the continuation of the power supply stop state of the electric device is associated with each type of electric device. In this example, the stop continuation allowable time is set separately depending on the time. In addition, you may make it set separately by other matters related to temperature, such as air temperature and room temperature.

  Next, the operation of the power management system 100 of this example will be described.

  FIG. 5 is a flowchart illustrating an example of power management processing in the power management system 100 of the present example. Here, in accordance with the operation of the administrator X managing the power management server 10, the power management server 10 instructs the electrical equipment to forcibly present the power supply to the store terminal 21 ( That is, here, it is assumed that only information related to the store A is registered in the power management master, and the case where the power supply to the electrical device is urgently stopped by an instruction from the store terminal 21 will be described as an example. It should be noted that explanations may be omitted except for processing particularly related to the present invention.

  In the power management process, first, the power management server 10 displays a power supply stop instruction command setting screen on its own display device according to the operation of the administrator X, and the emergency level is displayed on the power supply stop instruction command setting screen. Accept (step S101).

  FIG. 6 is an explanatory diagram illustrating an example of a power supply stop instruction command setting screen. As shown in FIG. 6, the power supply stop instruction command setting screen includes an emergency level input area 101 for inputting an emergency level, a power management master confirmation button 102 that is pressed when confirming the power management master, and an emergency level. There is provided a power supply stop execution button 103 that is pressed when executing a process for stopping power supply to an electrical device at an emergency level input to the input area 101. The emergency level input area 101 is configured so that any one of the set emergency levels can be selected by, for example, a pull-down menu.

  In the power supply stop instruction command setting screen, the administrator X confirms, for example, the ratio of the used power to the supplied power of the entire target area (for example, confirms by the real-time information provided by the power company), and according to the ratio The emergency level is determined, and the determined emergency level is input to the emergency level input area 101. When the emergency level is input, the administrator X presses the power supply stop execution button 103. When it is desired to confirm the contents of the power management master, the administrator X presses the power management master confirmation button 102. When the power management master confirmation button 102 is pressed, the power management server 10 displays a power management master display screen for displaying the contents of the power management master on the display device provided therein.

  When an emergency level is input to the emergency level input area 101 and the power supply stop execution button 103 is pressed, the power management server 10 refers to the power management master stored in the power management master DB 11 and inputs the emergency Electric devices associated with all emergency levels below the level (for example, level 1 and level 2 when level 2 is input) are identified as electric devices whose power supply is to be stopped (step S102). ).

  When the electric device to be stopped for power supply is specified, the power management server 10 determines the power supply stop target for the store terminal 21 connected to the electric device to be stopped for power supply. The electric device ID is presented, and a forced power supply stop instruction command for instructing to forcibly stop the power supply to the electric device indicated by the presented electric device ID is transmitted (step S103).

  When the forced power supply stop instruction command is received, the store terminal 21 outputs a power supply stop signal for instructing stop of power supply (power switch off) to each electric device indicated by the presented electric device ID. Transmit (step S104).

  Upon receipt of the power supply stop signal, each electrical device transmits a power supply stop completion notification indicating that the power supply is stopped by executing a power supply stop process to the store terminal 21, and then Stop processing (processing to turn off the power switch) is executed.

  When the store terminal 21 receives the power supply stop completion notification from all the electric devices (step S105), the power supply stop completion for reporting that the stop of the power supply of all the corresponding electric devices has been completed is completed. The report is transmitted to the power management server 10 (step S106). Note that if a power supply stop completion notification is not transmitted from some of the electric devices even after waiting for a certain period of time, the store terminal 21 indicates the electric devices that have completed the stop of the power supply. A power supply stop completion report including the ID may be transmitted.

  When receiving the power supply stop completion report, the power management server 10 updates the electric equipment operation information (step S107). In step S107, for the electronic device that has received the power supply stop completion report, processing for updating the number of operating units in the electric device operation information is performed in order to reflect that the power supply has been stopped.

  Next, the power management server 10 starts timing by a timer for counting the elapsed time after the power supply is stopped (step S108).

  Next, the power management server 10 creates a power supply stop completion status display screen for notifying an electric device whose power supply has been stopped, and a display device provided with the created power supply stop completion status display screen (Step S109). The power supply stop completion status displayed on the power supply stop completion status display screen is updated each time a power supply stop completion report is received, for example, when receiving a power supply stop completion report from a plurality of store terminals.

  FIG. 7 is an explanatory diagram illustrating an example of a power supply stop completion status display screen. As shown in FIG. 7, the power supply stop completion status display screen includes a display area 201 for displaying the power supply stop completion status, a display area 202 for displaying the total amount of power reduced by the power supply stop, and a power supply stop. An end button 203 that is pressed when the completion status display screen is closed, and a switching button 204 that is pressed when the display screen is switched to an operation status list display screen (hereinafter referred to as “honeycomb screen”) (see FIG. 9). Is provided.

  The administrator X grasps the power supply stop completion status by viewing the display area 201 of the power supply stop completion status display screen, and grasps the total amount of power reduced by viewing the display area 201.

  When receiving a switching request due to the pressing of the switching button on the power supply stop completion status display screen (Y in step S110), the power management server 10 refers to the electrical device operation information and displays the honeycomb screen (see FIG. 9). The generated honeycomb screen is displayed on the display device provided for itself instead of the generated power supply stop completion status display screen (step S111).

  When receiving the switching request due to the pressing of the switching button on the honeycomb screen (Y in Step S112), the power management server 10 changes to the honeycomb screen and displays the power supply stop completion status display screen (see FIG. 7). It is displayed again on the display device provided (step S109).

  When receiving an end request due to pressing of the end button on the power supply stop completion status display screen or the honeycomb screen (Y in step S113), the power management server 10 ends the processing here.

  As described above, in response to the operation of the administrator X managing the power management server 10, the power management server 10 instructs the electrical device to forcibly present power supply to the store terminal 21. In response to the instruction from the store terminal 21, a process of urgently stopping the power supply to the electrical device is executed.

  In the above example, a case has been described in which the power management server 10 mainly instructs the electrical device to instruct the one shop terminal 21 to present power supply, but the power management server 10 You may make it instruct | indicate to instruct | indicate with respect to a several store terminal to the electric equipment compulsorily to supply electric power. When the power management master as shown in FIG. 2 is registered, an instruction to forcibly present power supply to each store terminal managed by store A, store B, and store C, respectively. A process of instructing the electric device to perform is executed.

  In the above example, the power management server 10 is configured to issue an instruction to urgently stop power supply to each electrical device via the store terminal 21. However, the power management server 10 urgently supplies power directly to each electrical device. It may be configured to give an instruction to stop.

  In the above example, the process for forcibly stopping the power supply to the electrical equipment installed in the retail store has been described, but the electrical equipment may be installed in other facilities instead of the retail store. Good.

  FIG. 8 is a flowchart showing an example of honeycomb screen display processing in the power management system 100 of the present example. Here, when the power management server 10 performs processing for generating and displaying a honeycomb screen or updating the display content of the honeycomb screen in accordance with an operation of the administrator X who manages the power management server 10 or the like Will be described as an example. It should be noted that explanations may be omitted except for processing particularly related to the present invention.

  In the honeycomb screen display process, first, the power management server 10 generates a honeycomb screen by referring to the electrical equipment operation information when a predetermined operation is performed by the administrator X (for example, when the power is turned on or when the software is started). Then, the generated honeycomb screen is displayed on the display device provided in itself (step S201).

  FIG. 9 is an explanatory view showing an example of a honeycomb screen. When the honeycomb screen is closed, for example, as shown in FIG. 9, the operation status list display area 301 formed in a honeycomb structure in which the operation status display areas 301 a to 301 g of substantially regular hexagons are arranged substantially without gaps is closed. An end button 302 to be pressed and a switch button 303 to be pressed when switching the display screen to a power supply stop completion status display screen (see FIG. 7) are provided. The honeycomb screen is a display screen that displays electrical device operation information, and in each of the operation status display areas 301a to 301g provided for each type of electrical device, the name of the electrical device, the power source type used, The number of devices, the number of operating electrical devices, and the amount of power consumption are displayed. In addition, in FIG. 9, in addition to the name of the electric device, one or more pieces of information (for example, the number of electric devices and the number of electric devices in operation) are displayed in each of the operation status display areas 301a to 301g. An example will be described.

  Next, when the administrator X performs a selection operation of the operation status display areas 301a to 301g (for example, touch operation on the touch panel, click operation with the mouse), selection of the operation status display area is accepted (Y in step S202). (Hereinafter, the case where selection of the operation status display areas 301a and 301b is received will be described as an example.), The power management server 10 changes the display color of the operation status display areas 301a and 301b that have received the selection, Instead of the number of operating electrical devices, the number of stopped electrical devices is displayed (step S203). The number of stopped electrical devices is calculated by the power management server 10 by subtracting the number of operating devices from the total number of applicable electrical devices (“number” in FIG. 3).

  FIG. 10 is an explanatory diagram illustrating an example of the honeycomb screen when the display color of the operation status display area that has received the selection is changed. As shown in FIG. 10, the number of stopped electrical devices is displayed in the operation display areas 301 a and 301 b that have received the selection.

  Next, when the power management server 10 receives a power supply stop report from the store terminal 21 (Y in step S204), the power management server 10 updates the electric device operation information (step S205). That is, in order to reflect that the power supply of the electric device indicated by the power supply stop report is stopped, the number of operating electric devices in the electric device operation information is updated (subtracted).

  In this example, the store terminal 21 receives the power supply stop notification indicating that the power supply is stopped from the electrical device when the power supply is stopped in the electrical device. It is assumed that a process of transmitting a power supply stop report for reporting that the power supply of the electrical device is stopped to the power management server 10 is performed.

  When the electric device operation information is updated in step S205, the power management server 10 reverse-displays the operation status display area in which the electric device operation information with the updated operation number is displayed (hereinafter, operation display regions 301a and 301b). Is displayed as an example.) As in step S203, the number of stopped electrical devices is displayed instead of the number of operating electrical devices (step S206).

  FIG. 11 is an explanatory diagram illustrating an example of a honeycomb screen when an operation status display area in which updated electrical device operation information is displayed is highlighted. As shown in FIG. 11, the number of stopped electrical devices is displayed in the operation display areas 301 a and 301 b that are highlighted.

  Next, when the power management server 10 receives a power supply start report from the store terminal 21 (Y in step S207), the power management server 10 updates the electric equipment operation information (step S208). That is, in order to reflect that the power supply of the electric device indicated by the power supply start report is started, the number of operating electric devices in the electric device operation information is updated (added).

  In this example, when the store terminal 21 receives a power supply start notification indicating that power supply is started from the electrical device when an operation to start power supply is performed on the electrical device, It is assumed that a process of transmitting a power supply start report for reporting that the power supply of the electric device is started to the power management server 20 is performed.

  When the electric equipment operation information is updated in step S208, the power management server 10 updates the honeycomb screen (step S209). Specifically, the power management server 10 updates the value indicating the number of operating units (or the number of non-operating units) displayed in the operating status display area.

  When the honeycomb screen is updated, the power management server 10 refers to the timing result started in step S108 in the power management process, and has exceeded the stop continuation allowable time indicated by the stop continuation allowable time information (time-up) It is determined whether there is a device (step S210). If it is determined that there is no electrical device that has exceeded the allowable stop duration time (N in step S210), the power management server 10 proceeds to the process in step S202.

  On the other hand, if it is determined that there is an electrical device that has exceeded the allowable stop duration time (Y in step S210), the power management server 10 instructs the start of power supply to the electrical device that has exceeded the allowable stop duration time. Is transmitted to the shop terminal 21 via the communication network 30 (step S211).

  When the start command is transmitted and, for example, a report indicating that the supply of electricity is started is received from the store terminal 21, the power management server 10 updates the electric equipment operation information (step S212). When the electric operation information is updated, the power management server 10 updates the honeycomb screen based on the updated electric operation information, and proceeds to the process of step S202.

  As described above, in the above-described embodiment, the power management server 10 that manages the power source of the electric device that operates by the supplied power includes the name of the electric device, the power source type, and the number of the electric devices. The electric device operation information DB 12 stores electric device operation information associated with the number of electric devices in operation for each type of electric device, and includes an operation state display area (for example, a plurality of operation items) having a substantially regular hexagon. An operation status list display screen including an operation status list display region 301 formed in a honeycomb structure in which the status display regions 301a to 301g) are arranged substantially without gaps is displayed. Update the electrical equipment operation information, and change the name of the electrical equipment indicated by the electrical equipment operation information, the power source type used, the number of electrical equipment, and the number of electrical equipment in operation. Since the structure for displaying the respective operating status display area, it is possible to grasp the operational status of the installed electrical equipment throughout efficiently.

  In other words, information on the operating status of the electrical equipment installed at various locations in the operating status list display area formed in the honeycomb structure, and a plurality of operating status display areas constituting the operating status list display area for each type of electrical equipment By displaying on each, it becomes possible to efficiently grasp the operating status of the electrical equipment installed in each place.

  Further, in the above-described embodiment, the power management server 10 is operated by the user, and the selected operating status display area (for example, the operating status display) is selected in response to the operating status display area being selected by the user's operation. The display mode of the areas 301a and 301b) is changed to a predetermined mode (for example, a color indicating that it has been selected; see the operating status display areas 301a and 301b in FIG. 10), and the operation in the operating status display area is changed. Since the configuration is such that the number of non-operating electrical devices is displayed instead of the number of electrical devices in the middle, the operating status can be displayed in a display mode more suitable for the user. In other words, information can be displayed in a form that is easy for the user to understand by displaying the same information with different viewpoints.

  In the above-described embodiment, the power management server 10 receives the power supply stop notification indicating that the power supply is stopped from the electrical device when the power supply is stopped by the electrical device. From the terminal (for example, the store terminal 21), the power supply stop report for reporting that the power supply of the electric device is stopped is received (for example, step S204), and the electric power is received in response to the reception of the power supply stop report. The device operation information is updated (for example, step S205), and the display state of the operation status display area in which the updated electric device operation information is displayed in response to the update of the electric device operation information is specified (for example, displayed) (Refer to the operation status display areas 301a and 301b in FIG. 11) and the operating electricity in the operation status display area in which the display mode is changed. Since instead of vessels of the number has a configuration for displaying the number of electrical equipment out of service, it is possible to display the operational status in a display mode more suitable for the user.

  Further, in the above-described embodiment, the power management server 10 receives the power supply start notification indicating that the power supply starts from the electrical device when the power supply start operation is performed by the electrical device. From the terminal (for example, the store terminal 21), the power supply start report for reporting that the power supply of the electric device is started is received, and the electric device operation information is updated in response to the reception of the power supply start report. In response to the update of the electrical equipment operation information, the value of the number of active electrical equipments in the operation status display area where the updated electrical equipment operation information is displayed is updated. It becomes possible to display efficiently.

  Further, in the embodiment described above, the stop continuation allowable time in which the power management server 10 stores the stop continuation allowable time indicating the allowable time for allowing the continuation of the power supply stop state of the electric device for each type of the electric device is stored. The information DB 13 is provided, the time from when the electric power supply of the electric device is stopped is counted, and the electric power supply to the corresponding electric device is performed in accordance with the measured time reaching the stoppage allowable time of the corresponding electric device. Since the power supply start command for instructing the start of the power supply is transmitted via the communication network, the power consumption can be reduced within a range in which the failure of the electric device due to the stop of the power supply does not occur. It becomes like this.

  Although not particularly mentioned in the above-described embodiment, the power management server 10 performs the above-described various processes (for example, FIG. 5) according to a processing program (power management processing program) stored in a storage medium included in the power management server 10. , 8).
