Description

  The present invention relates to a power distribution system and a power distribution method for distributing power to power consuming devices used in a building, and in particular, priority devices to which power is preferentially supplied and non-priority devices other than priority devices. The present invention relates to a power distribution system and a power distribution method for distributing power to each device in a building where is installed.

  Development of a system to reduce environmental load by reducing power consumption in buildings by using sensors and IT technology, including Home Energy Management System (HEMS) and Building Energy Management System (BEMS) Is currently being actively conducted.

  Many of the above systems are systems that manage power consumption in buildings. One of the functions of these systems is “how much power is used in the building, when, where, and what. It is possible to visualize and present it to the user (so-called “visualization”). Another function of the system includes controlling the operation of the power consuming equipment in the building so that the power consumption in the building is optimized.

  By the way, as a technique for managing power consumption in a building, an upper limit value (target value) of power consumption within a predetermined period is set in advance, and the upper limit value and the actual power consumption during the predetermined period are set. An apparatus that presents the difference (more specifically, the remaining time during which power can be used in a predetermined period) to a resident of a house has already been disclosed (see, for example, Patent Document 1). The device described in Patent Document 1 also controls indoor power supply by intermittently connecting the indoor power distribution system when the actual power consumption exceeds a target value during a predetermined period. Thereby, in the house where the apparatus of patent document 1 was installed, appropriate management comes to be performed so that electric power is consumed systematically.

Japanese Utility Model Publication No. 5-4731

  However, in the technique disclosed in Patent Document 1, the power consumption is managed in units of houses, and as described above, the indoor power distribution system is intermittent when the actual power consumption exceeds the target value during a predetermined period. Therefore, while the indoor power distribution system is interrupted, even the equipment that should originally supply power is not supplied with power.

  On the other hand, when managing the power consumption in a house, it is also conceivable to manage the power consumption for each power consuming device used in the house and to control the operation status for each power consuming device. However, when managing the power consumption of individual devices, the total power consumption of all the power consumption devices in the house may not be reduced unless the operating status of other devices is taken into consideration. Can not be expected to reduce the environmental load. Even if the amount of electric power can be reduced by operation control for one device, the above power reduction is offset when power is wasted in other devices in the house. .

  Therefore, the present invention has been made in view of the above problems, and its purpose is to plan and rationalize each power consuming device in the building while optimizing the power consumption in the entire building. A power distribution system and a power distribution method for distributing power to

  The problem is that, according to the power distribution system of the present invention, both of the priority devices in the building in which the priority devices to which power is preferentially supplied and the non-priority devices other than the priority devices are installed. A power distribution system that distributes power to each of the power consuming devices, the measuring device installed to measure at least the power consumption of the non-prioritized device among the both power consuming devices, and the measuring device And an information processing server capable of communicating with the information processing server, wherein the information processing server sets a total target amount of power consumption consumed during a predetermined period in the entire building, A setting unit that is set for each power consuming device that is consumed during the predetermined period, and a measurement that indicates the measurement result by causing the measurement device to measure at least the power consumption of the non-priority device periodically during the predetermined period. A measurement data acquisition unit that acquires data, and the non-priority device is actually consumed between the start of the predetermined period and the time when the measurement device performs the most recent measurement. An accumulated amount calculating unit that calculates an accumulated amount of the consumed power, the target amount during the predetermined period of the non-priority device set by the setting unit, and the accumulated amount calculated by the accumulated amount calculating unit A processing execution unit that obtains a difference and executes a process according to the difference, and the setting unit sets the total target amount in advance, and then sets the target amount of each of the two power consuming devices. The target amount is set for each of both the power consuming devices so that the total does not exceed the total target amount, and the process execution unit performs a presentation process for presenting the difference to the user as the process. It is solved by executing.

  In the above power distribution system, since the total target amount of power consumption consumed during the predetermined period in the entire building is preset, if power is supplied to the building with the supply amount corresponding to this total target amount, the building It is possible to systematically reduce the overall environmental burden. And when setting the target amount of each of the priority devices and non-priority devices installed in the building, the total amount is set so as not to exceed the above total target amount. Compared with the case of managing consumption, it becomes possible to rationally distribute power to each power consuming device in the building. Specifically, the target amount of power consumption of non-priority equipment within the range of the amount obtained by subtracting the amount required to operate the priority equipment from the preset total target amount of power consumption of the entire building. Therefore, the power distribution amount to each of the priority device and the non-priority device is appropriately set. On the other hand, the user of the system (specifically, a resident of a building) can confirm the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption. It is possible to grasp the remaining time during which the non-priority device can be used during the period, and to raise the user's awareness of energy saving. As described above, according to the configuration of the present invention, the power distribution that can systematically and rationally distribute power to each power consuming device in the building while optimizing the power consumption in the entire building. A system is realized.

  In the power distribution system, the process execution unit displays information corresponding to the difference on a display screen of the user terminal as a presentation process toward a user terminal that can communicate with the information processing server. It is preferable to execute a process of transmitting information display data for the purpose.

  In the power distribution system, when the difference becomes 0, the process execution unit executes an interruption process for interrupting the distribution of power to the non-priority devices until the end of the predetermined period. The effect of this invention comes to be show | played effectively. In other words, in the above power distribution system, when the cumulative amount of power consumption actually consumed by the non-priority device exceeds the target amount, the operation of the non-priority device is forcibly terminated. As a result, it is possible to manage the power consumption in the entire building so as not to exceed the total target amount while continuing the operation of the priority device.

  Further, in the above power distribution system, when the notification process for notifying the user that the difference has reached a predetermined amount greater than 0 is performed by the user terminal, the process execution unit is configured so that the difference is When the predetermined amount is reached, it is even more preferable to execute a process of outputting a signal that instructs the user terminal to execute the notification process. With this configuration, it is possible to make the user aware that the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption has reached a predetermined amount, and promote energy saving behavior.

  Further, in the above power distribution system, the information processing server includes a control unit for adjusting the operation status of the non-priority device, and the user terminal adjusts the operation status of the non-priority device in the control unit. A receiving unit that receives an input operation performed by a user when performing the operation, a permission determination unit that determines whether to accept the input operation by the receiving unit, and a display unit that displays a determination result of the permission determination unit on the display screen And when the difference becomes zero, the process execution unit executes a process of transmitting a rejection signal for causing the permission determination unit to reject acceptance of the input operation by the accepting unit toward the user terminal. Then, it is more suitable. With this configuration, the user can confirm on the display screen of the user terminal that the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption is zero. In addition, since the user terminal side does not accept an input operation for adjusting the operation status of the non-priority device, the operation restriction of the non-priority device after the above difference becomes 0 is appropriately realized. Can do.

  In the above power distribution system, the setting unit may prevent the amount obtained by multiplying the total of the target amounts of the both power consuming devices by a predetermined safety factor from exceeding the total target amount. It is even more preferable to set the target amount for each of the both power consuming devices. According to such a configuration, it is possible to ensure a certain amount of electric power that can be used in the building in preparation for an emergency or emergency.

Further, according to the power distribution method of the present invention, the above-described problem is in a building in which power consumption devices of both priority devices to which power is preferentially supplied and non-priority devices other than the priority devices are installed. A power distribution method for distributing power to each of both of the power consuming devices, wherein a total target amount of power consumption consumed during a predetermined period in the entire building is set, and the power consumption of both the power consumption devices is set. A setting step for each power consuming device that each consumes during the predetermined period, and periodically during the predetermined period, using a measuring device, at least of the non-priority devices among the two power consuming devices A measurement data acquisition step of measuring power consumption and acquiring measurement data indicating a measurement result, and when the measurement data is aggregated and the latest measurement is performed by the measurement device from the start of the predetermined period A cumulative amount calculation step of calculating a cumulative amount of power consumption consumed by the non-priority device in the past, and the target amount during the predetermined period of the non-priority device set in the setting step, A process execution step of obtaining a difference from the cumulative amount calculated in the cumulative amount calculation step and executing a process according to the difference, and in the setting step, the total target amount is set in advance Then, the target amount of each of the both power consuming devices is set so that the total of the target amount of each of the both power consuming devices does not exceed the total target amount, and in the processing execution step, As a process, the present invention is solved by executing a presentation process for presenting the difference to the user.
In the above power distribution method, the power consumption target of the non-priority device is within the range obtained by subtracting the amount required for the operation of the priority device from the preset total target amount of power consumption of the entire building. The amount will be set. Thereby, the power distribution amount to each of the priority device and the non-priority device is appropriately set. On the other hand, since the user can check the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption, the remaining amount that can use the non-priority device during the predetermined period By grasping the time, it becomes possible to raise the user's awareness of energy saving. As a result, power can be distributed systematically and rationally to each power consuming device in the building while optimizing the power consumption in the entire building.

  According to the power distribution system and the power distribution method of the present invention, since the total target amount of power consumption consumed during the predetermined period in the entire building is set in advance, the supply amount corresponding to the total target amount is set in the building. If power is supplied, it will be possible to systematically reduce the environmental impact of the entire building. And when setting the target amount of each of the priority devices and non-priority devices installed in the building, the total amount is set so as not to exceed the above total target amount. Compared with the case of managing consumption, it becomes possible to rationally distribute power to each power consuming device in the building. In addition, since the user of this system can check the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption, the user can use the non-priority device for a predetermined period. By grasping the remaining time, it becomes possible to raise the user's awareness of energy saving. As a result, power can be distributed systematically and rationally to each power consuming device in the building while optimizing the power consumption in the entire building.

Below, the mechanism regarding power management is mainly demonstrated about the house H as an example of the building which mounts the power distribution system (henceforth this system S) which concerns on this embodiment. However, the house H is merely an example of a building, and the power distribution system of the present invention can be used in other buildings such as an office building, a building in a factory, a store, and the like.
In the following description, the user is a resident of the house H, in other words, a user of the system S.

  As shown in FIG. 1, the house H receives power from the commercial power source CP and distributes it to each of the power consuming devices installed in the house H through the distribution board 1. Here, the power consuming devices installed in the house H will be mainly divided into two types. One type is a priority device that is a device to which power should be preferentially supplied. The priority device corresponds to a device to which power should be constantly supplied (in other words, a device in a constantly operating state), and in the example illustrated in FIG. 1, a refrigerator corresponds.

  The other type is a non-priority device that is a power consuming device other than the priority device, such as a device whose power consumption varies depending on the lifestyle of the user. In the example shown in FIG. Applicable to electric water heaters. It should be noted that the type of each of the power consuming devices installed in the house H, which is a priority device or a non-priority device, may be determined in advance at the time of occupancy. It is good also as setting arbitrarily. In addition, when a new power consuming device is purchased, an input for registration may be performed on a registration screen (not shown), and priority device / non-priority device may be selected at the time of the input.

The power (system power) from the commercial power source CP is supplied to these power consuming devices via a wiring (not shown).
On the other hand, the user can visually recognize the power consumption of each device through a predetermined monitor (specifically, a display screen 21 of the operation pad 20 described later). Further, the user who has confirmed the power consumption of each device adjusts the operation status of each device in order to reduce the power consumption as an energy saving action.

  In order to provide the house H with the above performance, the present system S is mounted in the house H. More specifically, the system S has a role of measuring the power consumption of each individual power consuming device and the entire house H via a predetermined measuring device, and a role of visualizing the measurement result and presenting it to the user. In addition, it plays a role of controlling the operating status of each power consuming device in accordance with an instruction from the user. Here, the operation status is a concept indicating whether or not the power consuming device is operating (stopped), and in what operating conditions (for example, set temperature) when operating. is there.

  In addition to the above-described role, the system S manages the difference between the target amount set in advance for the power consumption and the actual power consumption for each device, and the power consumption device whose difference has reached a predetermined value. Also plays a role in blocking the distribution of power for a certain period.

  In order to describe the above role in more detail, the configuration of the system S will be described below with reference to FIGS. 1, 2A, and 2B. As shown in FIG. 1, this system S includes a home server 2 as an information processing server, a smart meter 3 as a measuring device installed to measure the power consumption of the entire house H, and individual power consumption. A CT sensor 4 as a measuring device installed for each device in order to measure the quantity is a main component.

  The home server 2 is a system server installed in the house H, and includes a CPU 11, a memory 12, a hard disk drive (hereinafter referred to as HDD) 13, and a communication interface 14 as shown in FIG. 2A. The above-mentioned role is realized by the cooperation. The memory 12 and the HDD 13 of the home server 2 store a program for causing the home server 2 to perform the above-described role. In addition, although it is good also as installing the information processing server which is an apparatus for implement | achieving the above-mentioned role in the house H like this embodiment, it is not limited to this, The outside of the house H ( For example, it may be set in the management company of the house H.

The home server 2 is communicably connected to the smart meter 3 and the CT sensor 4 via the home network N1. And the in-home server 2 makes these measuring devices measure power consumption regularly, and acquires the measurement data which shows a measurement result.
In the present embodiment, the smart meter 3 is a prepaid wattmeter, and, for example, as shown in FIG. 1, through the Ethernet (registered trademark; hereinafter the same) N2, for example, management of the power company EC (commercial power supply CP). It is communicably connected to a center server 5 installed in the company. Since the smart meter 3 is installed in the house H, the power consumption fee is prepaid, and the power consumption in the entire house H is managed so as to be within a range corresponding to the prepaid charge. Is possible.

  More specifically, the user uses the card reader (not shown) installed in the house H to the electric power company EC for the power consumption (expected amount) for a predetermined period (for example, the period from the beginning of the month to the end of the month). A corresponding power usage fee can be paid before the predetermined period. The electric power company EC supplies electric power (system power) from the commercial power supply CP with the power consumption corresponding to the prepaid power usage fee as an upper limit for a predetermined period.

  On the other hand, the smart meter 3 is installed in a power distribution line L that is laid in order to draw system power into the house H, and measures power consumption in the entire house H. The measurement result by the smart meter 3 is transmitted as electronic data (measurement data) to the home server 2 through the home network N1 and to the center server 5 of the power company EC through the Ethernet N2.

  If the power consumption of the entire house H exceeds the amount corresponding to the prepaid power usage amount during the predetermined period, the power company EC pays the user additional payment of the power usage amount. If the command is not accepted, the power transmission to the house H is temporarily interrupted.

  By the way, the home server 2 can communicate with the power consuming device in the house H and the operation pad 20 used by the user in the house H through the home network N1. And if a user performs input operation for adjusting the driving condition of each power consumption apparatus through the operation pad 20, the home server 2 will control each power consumption apparatus according to the said input operation. That is, in the present system S, each power consuming device is controlled via the home server 2.

  More specifically, the operation pad 20 operated by the user is a touch panel type user terminal, specifically a tablet terminal (portable information terminal). Through the display screen 21 of the operation pad 20, the user can check the operation status and power consumption of each device, and can further adjust the operation status of each device.

The display screen 21 of the operation pad 20 will be described more specifically with reference to FIG.
The operation pad 20 displays the management window W shown in FIG. 3 on the display screen 21, and through the management window W, it is possible to check the operating status and power consumption of each device. In the present embodiment, as shown in FIG. 3, the management window W is divided by the number of power consuming devices in the house H, so the user confirms the driving status, power consumption, etc. for each device. can do. Further, since the management window W is provided with a space for displaying the power consumption of the entire house H, the user can check the power consumption of the entire house H through the management window W. .

  On the other hand, the management window W is provided with an operation button for changing the operating state of the power consuming device, and the user presses an area of the display screen 21 of the operation pad 20 where the operation button is displayed. Thus, the operation status of the power consuming device can be adjusted. In other words, the operation pad 20 can accept a user input operation through the display screen 21.

  More specifically, as shown in FIG. 3, the management window W includes a column C1 indicating the start / stop status of each power consuming device and a column C2 indicating operating conditions (set temperature in the case shown in FIG. 3). Is displayed. The management window W includes a button for switching on / off of the power consuming device (hereinafter referred to as “start / stop switching button”) B1, and buttons for changing operating conditions (hereinafter referred to as “setting change buttons”) B2a and B2b. Is provided for each device. When the user presses these buttons B1, B2a, and B2b, the operation pad 20 receives user input operations. Thereafter, the operation pad 20 outputs a signal corresponding to the user's input operation to the in-home server 2, and the in-home server 2 that has received the signal is the target of the user's input operation based on the signal. Control the operating status of power consuming equipment.

  In the present embodiment, among the power consuming devices in the house H, the device that satisfies a predetermined requirement is forcibly interrupted, and the operation pad 20 is also used to adjust the operation status of the device. The user's input operation is not accepted. More specifically, as shown in FIG. 4, during the management window W, the buttons B1, B2a, and B2b for adjusting the operation status of the device that satisfies the predetermined requirement are not displayed. Such processing will be described in detail later.

  As described above, in this embodiment, confirmation and switching of the driving status of all the power consuming devices in the house H are integrated into one operation pad 20, and the user can use the operation pad 20 to change the house. It is possible to check and switch the operating status of all the power consuming devices in H. However, the present invention is not limited to this, and an interface for confirming or switching the driving status may be provided for each device, such as a conventional remote control or operation panel.

  In the present embodiment, an example in which the operation pad 20 is a tablet terminal (portable information terminal) has been described. However, the present invention is not limited thereto, and may be a PC, a smartphone, a fixed operation panel, or the like. .

  By the way, in the present system S, as described above, the difference between the target amount set in advance for the power consumption and the actual power consumption is managed for each device, and the device for which the difference has reached a predetermined value is constant. Periodic power distribution is to be cut off. In order to explain this function, the configuration of the system S will be described again from the functional aspect.

As shown in FIG. 2B, the home server 2 includes a setting unit 15A, a measurement data acquisition unit 15B, a cumulative amount calculation unit 15C, a process execution unit 15D, and a control unit 15E as components.
Hereinafter, each part of the home server 2 will be described.

  The setting unit 15A includes the CPU 11, the memory 12, the HDD 13, the communication interface 14, and a target setting program of the home server 2, and targets for power consumption consumed during a predetermined period of each power consuming device in the house H. The amount is set in advance for each power consuming device. Here, as described above, each power consuming device in the house H includes a priority device and a non-priority device, and the setting unit 15A according to the present embodiment uses power for both the priority device and the non-priority device. Set the target amount of consumption.

  In the present embodiment, a target amount of power consumption consumed for one month is set as a target amount of power consumption consumed during a predetermined period. More specifically, the setting is performed by the user performing an operation (target setting operation) for setting the target amount through the operation pad 20 at a predetermined time (for example, a predetermined time on the day corresponding to the beginning of the month). The unit 15A sets the target amount for the current month for each device in accordance with the operation. Note that the target amount setting cycle is not limited to one month, and can be set arbitrarily such as one day or one week.

  In addition, the setting unit 15A according to this embodiment sets the target amount of power consumption for the current month for each of the priority device and the non-priority device, and the power consumption consumed during the current month in the entire house H. The total target amount of quantity is preset. That is, in this embodiment, after setting the total target amount of the power consumption consumed in the whole house H during the predetermined period in advance, the target amounts of both the power consumption devices are set. Note that the total target amount of power consumption consumed by the entire house H is also set according to a target setting operation performed by the user through the operation pad 20 at a predetermined time.

  Furthermore, in this embodiment, after setting the total target amount of power consumption consumed during the current month for the entire house H, the target for the current month's power consumption for each of the priority device and the non-priority device. When setting the amount, the target amount of each of the power consuming devices is set so that the total target amount of both of the power consuming devices does not exceed the total target amount. The procedure for setting the target amount by the setting unit 15A will be described in detail later.

  As described above, when the target amount of each power consuming device and the total target amount for the entire house H are set, data indicating these target amounts is generated by the home server 2, and the data is operated through the home network N1. Received by the pad 20. On the operation pad 20 side, the received data is expanded and each target amount is displayed on the display screen 21 (more specifically, the management window W) (see FIG. 3).

  The measurement data acquisition unit 15B includes the CPU 11, the memory 12, the HDD 13, the communication interface 14, and the measurement execution program of the home server 2, and regularly measures the power consumption of the entire house H during the month. To obtain measurement data indicating a measurement result. Similarly, the measurement data acquisition unit 15B causes the CT sensor 4 to measure the power consumption of each power consuming device in the house H, and acquires measurement data indicating the measurement result for each device. The measurement data acquired by the measurement data acquisition unit 15B is temporarily stored in the memory 12, and then stored in the HDD 13 in units of power consuming devices.

  In addition, the measurement data acquisition process by the measurement data acquisition unit 15B is performed every predetermined time, and is performed every hour in the present embodiment. However, the present invention is not limited to this, and the measurement cycle can be arbitrarily set.

  The cumulative amount calculation unit 15C includes the CPU 11, the memory 12, the HDD 13, and the cumulative amount calculation program of the home server 2, reads the accumulated measurement data, aggregates the measurement data, and starts the current month (specifically Specifically, the cumulative amount of power consumption from midnight on the day corresponding to the beginning of the month is calculated for each power consuming device. In other words, the cumulative amount calculation unit 15C actually consumes power from the start of the current month until the time when the latest measurement by the CT sensor 4 is executed (hereinafter, the time when the latest measurement data acquisition process is executed). The cumulative amount is calculated.

  Note that the cumulative amount calculation step by the cumulative amount calculation unit 15C is periodically performed, and in this embodiment, is performed every time the measurement data acquisition step is executed. However, the present invention is not limited to this, and the period for calculating the cumulative amount can be arbitrarily set.

  Furthermore, in the present embodiment, the cumulative amount calculation unit 15C calculates the cumulative amount for each power consuming device in the house H, and actually performs from the start of the current month to the execution time of the latest measurement data acquisition process. The total cumulative amount of power consumption consumed in the entire house H is calculated. When the cumulative amount of power consumption for the current month is calculated for each power consuming device and the entire house H, data indicating these cumulative amounts is generated by the home server 2, and the data is manipulated through the home network N1. Received by the pad 20. On the operation pad 20 side, the received data is expanded, and each accumulated amount is displayed on the display screen 21 (more specifically, the management window W) (see FIG. 3).

  The process execution unit 15D includes the CPU 11, the memory 12, the HDD 13, the communication interface 14, and the process execution program of the home server 2, and the target amount and cumulative amount calculation unit of the current power consumption set by the setting unit 15A for the current month. A difference from the accumulated amount of power consumption of the current month calculated by 15C is obtained, and processing corresponding to the difference is executed.

  Here, as described above, the target amount is set for each power consuming device in the house H, and is also set for the power consumption in the entire house H. Similarly, as described above, the cumulative amount from the start point of the current month to the execution point of the most recent measurement data acquisition process is calculated for each power consuming device, and also calculated for the power consumption of the entire house H. The For this reason, when the process execution unit 15D obtains the above difference, it obtains the difference between the corresponding target amount and the accumulated amount. For example, the difference for the entire house H is obtained by subtracting the cumulative amount of power consumption for the entire house H for the current month from the target amount for the power consumption for the entire house H for the current month.

  And the process execution part 15D performs a predetermined | prescribed process according to the difference calculated | required with respect to each of a non-priority apparatus among the calculated | required differences. More specifically, the process execution unit 15D executes a presentation process for presenting the above difference to the user as a process. In particular, in the present embodiment, the process execution unit 15D divides the magnitude of the difference into three stages. Execute the process. Hereinafter, the process of each step will be described.

First, the first stage process will be described.
The first stage process corresponds to the presentation process described above, and the difference obtained for the non-priority device is from the aforementioned target amount to a predetermined amount (specifically, the amount set for the second stage process). When it is within the range, this is a process of transmitting information display data for displaying information corresponding to the difference on the display screen 21 of the operation pad 20 toward the operation pad 20. When the operation pad 20 receives the information display data, the operation pad 20 expands the data and displays the amount of power corresponding to the difference obtained for the non-priority device in the corresponding area (the power for the non-priority device). In the display area). By confirming such display, the user can compare the target amount of power consumption for the current month set for the non-priority device, and the amount of power that can be consumed during operation of the non-priority device during the current month. It is possible to grasp the rest of

  In the present embodiment, the amount of power corresponding to the difference is displayed, and the power consumption time corresponding to the difference (in other words, the remaining time during which the power consumption device can be operated in the current month) is also displayed ( (See FIG. 3). In other words, in the information display data, the power amount corresponding to the difference obtained for the non-priority device and the power consumption time corresponding to the difference are displayed together on the display screen 21 of the operation pad 20. Will be included. The information corresponding to the difference may be information other than the information described above (specifically, the amount of power and power consumption corresponding to the difference). For example, the amount of money (electricity corresponding to the difference described above) Or a symbol, graph or illustration corresponding to the above difference.

  Further, in the present embodiment, the process execution unit 15D obtains the difference between the target amount and the cumulative amount (actual amount) of the power consumption for the non-priority device, and similarly applies the difference for the priority device and the entire house H. Is supposed to ask for. The information display data includes the above information (specifically, the amount of power corresponding to the difference) for the difference obtained for the priority equipment and the entire house H, as well as the difference obtained for the non-priority equipment. And data for displaying the power consumption time).

Next, the second stage process will be described.
The second stage process corresponds to the above-described presentation process, and outputs a predetermined signal toward the operation pad 20 through the home network N1 when the difference obtained for the non-priority device reaches a predetermined amount. This is signal output processing. When the operation pad 20 receives the signal output by the signal output process, a notification process for notifying the user that the difference has reached a predetermined amount is performed.

  More specifically, when the cumulative amount of power consumption actually consumed by a non-priority device during the current month approaches the target amount set for that device for the current month, When the discrepancy (that is, the difference) becomes smaller than a predetermined amount, the process execution unit 15D outputs a signal for instructing the operation pad 20 to execute the notification process in order to notify the user of the fact. .

  Note that the set amount for defining the execution point of the signal output processing (that is, the above-described predetermined amount) is an amount larger than 0, and is preferably set with reference to the target amount. It is desirable to set within a range of 5 to 20% of the above. However, this range is merely an example, and can be set to any amount as long as the amount is larger than zero. As a notification method performed on the operation pad 20 side, any warning sound, lamp lighting, or any other suitable notification means can be used without limitation.

Finally, the third stage process will be described.
In the third stage, the power supply circuit to the non-priority device is shut off when the difference obtained for the non-priority device reaches 0, and the power to the non-priority device is terminated until the end of the current month. Suspend processing to interrupt the distribution of

  More specifically, the process execution unit 15D determines that a certain non-priority device when the accumulated value of the power consumption actually consumed in the month reaches a target amount and the above difference becomes zero. By operating a cutoff switch (not shown) provided in the power supply circuit, the power supply circuit is cut off and the operation of a certain non-priority device is forcibly stopped. Thereafter, the above-described cutoff switch is kept in the on state until the end of the current month, and as a result, the interruption of power distribution to a certain non-priority device is maintained until the end of the current month.

  In the present embodiment, even when the difference obtained for the priority device reaches 0, the distribution of power to the priority device is continued without interruption. This is because priority devices such as refrigerators are highly required to continue operation. However, the present invention is not limited to this, and power distribution may be stopped for priority devices when the above difference reaches zero.

  Further, in the present embodiment, when the difference obtained for the non-priority device reaches 0, the process execution unit 15D determines the operation status of the non-priority device in addition to the above-described interruption process as a third-stage process. A process of restricting an input operation performed by the user for adjustment is executed.

  More specifically, the in-home server 2 includes a control unit 15E as a component as shown in FIG. 2B. The control unit 15E includes the CPU 11, the memory 12, the HDD 13, the communication interface 14, and a processing execution program. The control unit 15E outputs a signal output from the operation pad 20 (specifically, for adjusting the operating status of the power consuming device). The operation status of each of the power consuming devices including the non-priority devices is adjusted based on the signal according to the input operation performed by the user.

  On the other hand, on the operation pad 20 side, as shown in FIG. 2B, a receiving unit 22A that receives an input operation performed by the user through the display screen 21, a permission determination unit 22B that determines whether to accept an input operation by the receiving unit 22A, And a display unit 22C for displaying the determination result of the permission / refusal determination unit 22B on the display screen 21.

  The accepting unit 22A accepts an input operation performed by the user when the control unit 15E of the in-home server 2 adjusts the driving status of the non-priority device only when the permission determination unit 22B permits, and the permission determination unit 22B rejects Does not accept the above input operation. When the acceptance / rejection determination unit 22B determines whether or not the input unit 22A accepts the input operation, the determination result is displayed on the display screen 21 by the display unit 22C. More specifically, when the decision to accept the input operation is made, the above-described start / stop switching button B1 and temperature setting buttons B2a and B2b are displayed on the display screen 21, whereas the decision to refuse the acceptance is made. In such a case, these buttons B1, B2a, B2b are not displayed (see FIG. 4).

Then, when the difference obtained for a certain non-priority device becomes 0, the processing execution unit 15D of the home server 2 rejects the permission determination unit 22B to accept the input operation toward the operation pad 20. A process of transmitting a signal is executed. This restricts the acceptance of user input operations for certain non-priority devices (devices with a difference of 0).
To explain in an easy-to-understand manner, on the side of the operation pad 20 that has received the rejection signal, the acceptance / rejection determination unit 22B performs a user input operation performed when adjusting the driving state of a certain non-priority device by the reception unit 22A. Make a decision to refuse acceptance. In accordance with this determination, the display unit 22C hides the start / stop switching button B1 and the temperature setting buttons B2a and B2b for a certain non-priority device. As a result, the user's input operation to a certain non-priority device cannot be accepted.

  As described above, a non-priority device with a difference of 0 is in a state where it cannot accept a user input operation for adjusting the driving situation, and the display screen 21 of the operation pad 20 displays the output for the device. The stop switching button B1 and the temperature setting buttons B2a and B2b are not displayed. This state continues until the end of the current month, and if the user checks the display screen 21 of the operation pad 20 during this period, the non-priority devices that cannot accept the input operation (that is, the buttons B1, B2a, and B2b are not displayed). For the non-priority device displayed), it can be grasped that the difference is zero.

  In the present embodiment, the non-priority device is the only device that cannot accept the user's input operation for adjusting the driving situation when the above difference becomes zero. However, the present invention is not limited to this, and the priority device may not accept the user's input operation for adjusting the driving situation when the above difference reaches zero.

  When the third stage processing is performed, that is, when a non-priority device having the difference of 0 is generated, as described above, power distribution to the non-priority device is interrupted, And the state which does not receive the user's input operation for adjusting the driving | running state of the said non-priority apparatus is maintained until the end time of this month. On the other hand, when the current month ends and the next month starts, the above state is canceled, and power distribution to the non-priority devices for which power distribution has been suspended is resumed to adjust the operating status of the non-priority devices. It becomes possible again to accept the user's input operation.

  Under the above configuration, in the present system S, as described above, the target amount preset for the power consumption, the accumulated amount of the actual power consumption, and the difference between the two can be confirmed for each device. For non-priority devices whose difference has reached 0, power distribution will be cut off until the end of the current month. As a result, a system capable of systematically and rationally distributing power to each power consuming device in the house H while optimizing the power consumption in the entire house H is realized. .

  More specifically, if a total target amount of power consumption consumed during the current month in the entire house H is set in advance and the amount of power supplied according to the total target amount is distributed in the house H, It becomes possible to systematically advance the reduction of the environmental load in the entire house H.

  In addition, when setting the target amount for each of the priority equipment and non-priority equipment installed in the house H, the total amount is set so as not to exceed the total target amount. Compared with the case where the power consumption of each power consuming device is managed without considering the above, it becomes possible to rationally distribute power to each power consuming device in the house H. In other words, in the present embodiment, the power consumption of the non-priority device is within the range obtained by subtracting the amount required for the operation of the priority device from the preset total target amount of the power consumption of the entire house H. A target amount will be set. As a result, the power distribution amount to each of the priority device and the non-priority device is appropriately set.

  Further, the system S presents the user with the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption, so that the user can confirm the difference and It becomes possible to grasp the remaining time in which the priority device can be used, and to raise the user's awareness of energy saving.

  With the above operation, the present system S can distribute power in a planned and rational manner to each power consuming device in the house H while optimizing the power consumption in the entire house H. It is. Also, as in this embodiment, when the smart meter 3 is installed and the upper limit of power consumption in the entire house H in the current month is set to an amount corresponding to the prepaid power usage fee, The above-described effects are particularly effective.

  In other words, when the total target amount of power consumption for the entire house H is set and the power usage fee corresponding to the total target amount is paid in advance, the total target amount is supplied to the house H in the current month. Therefore, when setting the target amount of each of the priority device and the non-priority device, if the total amount is set so as not to exceed the above upper limit, the power consumption of the entire house H The power consumption required for the operation of the priority device can be secured while suppressing the above within the above upper limit range.

Next, the power distribution method by this system S which produces the above effect is demonstrated, referring FIGS.
The power distribution method according to the present system S is a power distribution method for distributing power to each of both power consuming devices in a house H in which both power consuming devices, both priority devices and non-priority devices, are installed. Is adopted in the power distribution process. The process proceeds in the order shown in FIG. 5 and starts with a setting step by the home server 2 (S001).

  The setting step S001 sets a total target amount of power consumption consumed in a predetermined period in the entire house H, and power consumption consumed by each of the priority device and the non-priority device during the same period. This step is set for each device, and in this embodiment, a target amount of power consumption (target amount for the current month) to be consumed in one month is set.

  And in this embodiment, after presetting the total target amount in the entire house H for the current month, the total target amount of each power consuming device does not exceed the above total target amount. Set the target amount.

  In particular, in the present embodiment, the target amount of each power consuming device is set so that the amount obtained by multiplying the total target amount of each power consuming device by a predetermined safety factor does not exceed the above total target amount. . As a result, it is possible to secure a certain amount of power that can be used in the house H in preparation for an emergency or emergency. For example, even if the total amount of power consumption of each power consuming device exceeds the initial estimated amount, the amount obtained by multiplying the estimated amount by the safety factor does not exceed the target amount. If the amount is set, the amount of power required for the operation of the priority device can be secured. In the present embodiment, a surplus of power consumption is secured by multiplying the total target amount of each power consuming device by a predetermined safety factor, but the present invention is not limited to this. It is also possible to secure the surplus by adding (adding) a certain amount of power consumption to the sum of the above.

  The setting step S001 is executed by the setting unit 15A when the user performs an operation (target setting operation) for setting the target amount through the operation pad 20 at a predetermined time at the beginning of the month. In the present embodiment, as described above, in the setting step S001, first, the total target amount of power consumption in the entire house H for the current month is set, and then the target amount of power consumption for each power consuming device for the current month. Is set for each device.

  A procedure for setting each target amount in the setting step S001 will be described with reference to FIGS. First, the user performs a predetermined operation to set a total target amount of power consumption for the entire house H on the display screen 21 of the operation pad 20 (target amount setting window Wm1 shown in FIG. 6). ) Is displayed. In this target amount setting window Wm1, the cumulative amount (actual amount) of power consumption consumed in the entire house H in the previous month (last month) is displayed, and the total target amount for the current month is set. Buttons (hereinafter referred to as total target amount setting buttons) B3a, B3b, and B3c are provided.

  When any one of the total target amount setting buttons B3a, B3b, and B3c is pressed by the user, a signal corresponding to the pressed button is transmitted from the operation pad 20 to the home server 2. Is done. When the home server 2 receives the signal, the setting unit 15A sets the total target amount for the current month based on the signal (S011 in FIG. 9). More specifically, the setting unit 15A displays the increase / decrease rate displayed on the button pressed by the user among the total target amount setting buttons B3a, B3b, B3c (in the example shown in FIG. 6, + 10%, 0%, −10%) is set as the total target amount by adding to the cumulative amount of power consumption in the previous month (last month).

  As described above, in the present embodiment, the rate of increase / decrease with respect to the accumulated amount of power consumption in the entire house H in the previous month (last month) is set to the operation pad 20 (more specifically, the total target on the display screen 21). The user is made to select through the amount setting buttons B3a, B3b, B3c), and the total target amount is set based on the selection result. However, the above procedure is merely an example of a procedure for setting the total target amount, and the total target amount is set by other procedures, for example, a method of directly inputting a numerical value corresponding to the total target amount. Also good.

  After setting the total target amount of power consumption of the entire house H, a window (target amount setting window Wm2 shown in FIG. 7) for setting the target amount of power consumption of the priority device is displayed on the operation pad 20. It is displayed on the display screen 21. The target amount setting window Wm2 displays a cumulative amount (actual amount) of power consumption consumed by the priority device in the previous month (last month), and a button for setting the target amount for the current month (hereinafter referred to as the target amount). , Target amount setting buttons) B4a, B4b, B4c are provided. When one of the target amount setting buttons B4a, B4b, and B4c is pressed by the user, a signal corresponding to the pressed button is transmitted from the operation pad 20 to the home server 2. The Thereafter, the target amount of power consumption of the priority device is set by the same procedure as that for setting the total target amount of power consumption of the entire house H (S012 in FIG. 9).

  When a plurality of priority devices are installed in the house H, the target amount of power consumption is set for each priority device. Specifically, the target displayed on the display screen 21 of the operation pad 20 is set. The amount setting window Wm2 is switched for each priority device. Then, when the target amount of power consumption for the current month is set for all the priority devices, the setting of the target amount for the priority device is completed.

  After setting the target amount of power consumption of the priority device, a window (target amount setting window Wm3 shown in FIG. 8) for setting the target amount of power consumption of the non-priority device is displayed on the operation pad 20. It is displayed on the screen 21. In this target amount setting window Wm3, the cumulative amount (actual amount) of power consumption consumed by non-priority devices in the previous month (last month) is displayed, and a button ( Hereinafter, target amount setting buttons) B5a, B5b, and B5c are provided.

  When any one of the target amount setting buttons B5a, B5b, and B5c is pressed by the user, a signal corresponding to the pressed button is transmitted from the operation pad 20 to the home server 2. The When the home server 2 receives the above signal, the setting unit 15A sets the month of the previous period by the amount corresponding to the increase / decrease rate displayed on the button pressed by the user among the target amount setting buttons B5a, B5b, and B5c. An amount obtained by adding the accumulated amount of power consumption of last month) is calculated as a temporary target amount (S013 in FIG. 9). When a plurality of non-priority devices are installed in the house H, the provisional target amount is calculated for each non-priority device.

  After the provisional target amount for the non-priority device is calculated, the setting unit 15A of the home server 2 determines the provisional target amount (the sum of the provisional target amounts when a plurality of non-priority devices are installed). ) And the target amount of power consumption of the priority device. If the total exceeds the total target amount of power consumption of the entire house H (Yes in S014 in FIG. 9), the setting unit 15A displays data for displaying an error message on the display screen 21 of the operation pad 20. Is transmitted toward the operation pad 20. On the operation pad 20 side that has received the data, the above error message is displayed on the display screen 21 and the user is requested to redo the input operation.

  Furthermore, in the present embodiment, the setting unit 15A multiplies the above total by a predetermined safety factor, and when the amount obtained as the product exceeds the target amount of the entire house H (Yes in S015 in FIG. 9), As in the case of, data for displaying an error message on the display screen 21 of the operation pad 20 is generated and transmitted. On the other hand, when the amount obtained by multiplying the above total by a predetermined safety factor does not exceed the total target amount of the entire house H, the temporary target amount calculated for the non-priority device is used as the regular target amount. Accordingly, the target amount for the current month for the non-priority device is set (S016 in FIG. 9).

  Through the series of procedures described above, the total target amount of power consumption of the entire house H in the current month and the target amount of power consumption of each power consumption device in the current month are set. The setting unit 15 </ b> A generates data for displaying each set target amount on the display screen 21 of the operation pad 20 and transmits the data to the operation pad 20. On the operation pad 20 side that has received the data, processing for analyzing the data and displaying each target amount on the display screen 21 (more specifically, the management window W) is executed.

  Thereafter, during this month, power from the commercial power supply CP is distributed to each power consuming device, and each power consuming device is operated under the operating conditions adjusted by the user through the operation pad 20 under the control of the control unit 15E of the home server 2. I will drive.

  On the other hand, during the current month, the measurement data acquisition process by the measurement data acquisition unit 15B is periodically executed (S002). In this process S002, while measuring the power consumption of the whole house H using the smart meter 3, the measurement data which shows the said measurement result are acquired, and the power consumption of each power consumption apparatus is calculated using the CT sensor 4. Measurement is performed to obtain measurement data indicating the measurement result. The acquired measurement data is temporarily stored in the memory 12 and then stored in the HDD 13 for each device.

  During the current month, the cumulative amount calculation step is also periodically executed (S003). In particular, in this embodiment, this step S003 is executed each time the measurement data acquisition step S002 is executed. In this step S003, the cumulative amount calculation unit 15C of the home server 2 totals the measurement data, and each power consuming device actually consumes from the start time of the current month to the execution time of the latest measurement data acquisition process. Calculate the cumulative amount of power consumption for each device. Moreover, in this process S003, measurement data is totaled and the total accumulation amount of the electric power consumption actually consumed in the whole house H from the start time of this month to the execution time of the latest measurement data acquisition process is calculated. To do.

  Then, for each power consuming device and the entire house H, when the cumulative amount of power consumption from the start of the current month to the execution time of the latest measurement data acquisition step is calculated, data indicating these cumulative amounts is obtained. The data generated by the home server 2 is received by the operation pad 20 through the home network N1. On the operation pad 20 side, the received data is expanded, and each accumulated amount is displayed on the display screen 21 (more specifically, the management window W).

  Furthermore, in the present embodiment, every time the cumulative amount calculation step S003 is executed, a process execution step in which the process execution unit 15D of the home server 2 executes a predetermined process is performed (S004). In this step S004, first, a difference from the cumulative amount calculated in the cumulative amount calculation step S003 set in the setting step S001 is obtained, and processing corresponding to the difference is executed. In addition, about a difference, it calculates | requires according to the power consumption apparatus installed in the house H, Furthermore, it calculates | requires also about the whole house H. In the present embodiment, the processing according to the above difference is executed only for non-priority devices among the power consuming devices installed in the house H.

As described above, the process executed in this step S004 is divided into three stages according to the magnitude of the difference, and the process in the first stage is performed by displaying the operation pad 20 toward the operation pad 20. This is a process of transmitting information display data for displaying information corresponding to the difference on the screen 21.
The first stage processing is executed when the above difference has not reached a predetermined amount (set amount for the second stage processing) greater than 0 (S021, S22 in FIG. 10).

  On the other hand, on the operation pad 20 side that has received the information display data, the amount of power corresponding to the difference obtained for the non-priority device is displayed in the corresponding area on the management window W. By confirming such a display, the user compares the target amount of power consumption for the current month set for the non-priority device with the remaining amount of power consumed by operating the non-priority device during the current month. It becomes possible to grasp the amount. And by said effect | action, a user is aroused energy saving consciousness and comes to perform energy saving action, such as adjusting the driving | running state of a non-priority apparatus according to the magnitude | size of the displayed difference.

  In the present embodiment, as described above, the amount of power corresponding to the difference is displayed, and the power consumption time corresponding to the difference (that is, the remaining time during which the power consumption device can be operated in the current month) is also displayed. Is displayed. Thereby, it becomes easy for the user to manage the power consumption, and thus it is possible to promote the practice of the energy saving action.

  The second-stage process is a process that is executed when the difference obtained for the non-priority device reaches a predetermined amount, and outputs a signal that instructs the operation pad 20 to execute the above-described notification process ( In FIG. 10, S023 and S024). On the operation pad 20 side that receives this signal, a notification process (specifically, generation of a warning sound or lamp lighting) is performed to notify the user that the above difference has reached a predetermined amount. As a result, the difference between the target amount of power consumption of the non-priority device and the cumulative amount of actual power consumption has reached a predetermined amount (for simplicity, if the operation of the non-priority device is maintained as it is, It is possible to make the user aware that the above difference will soon be zero) and to encourage the user to save energy.

In the third stage, the power supply circuit to the non-priority device is shut off when the difference obtained for the non-priority device reaches 0, and the power to the non-priority device is terminated until the end of the current month. Is interrupt processing (S025 in FIG. 10).
By executing such processing, the effect of the system S described above is effectively exhibited. In other words, in the present system S, when the cumulative amount of power consumption actually consumed by the non-priority device exceeds the target amount, the operation of the non-priority device is forcibly stopped and maintained in a stopped state until the end of the current month. To do. As a result, in the present system S, it is possible to manage the power consumption in the entire house H so as not to exceed the set total target amount while continuing the operation of the priority device.

Further, in the third stage process, in addition to the above-described process, a rejection signal is transmitted to the operation pad 20 to reject the acceptance of the input operation performed by the user when adjusting the driving status of the non-priority device. Execute the process. On the operation pad 20 side that has received the rejection signal, the permission / rejection determination unit 22B determines to reject the acceptance of the user's input operation to the non-priority device whose difference is 0, and reflects the determination result to display the display screen. The start / stop switching button B1 and the temperature setting buttons B2a and B2b for the non-priority device displayed on the screen 21 are not displayed.
By executing such a process, the user has found that the difference between the target amount of power consumption of the non-priority device and the accumulated amount of actual power consumption has become zero (turned to the non-priority device). Can be confirmed on the display screen 21 of the operation pad 20. Further, since the input operation for adjusting the operation status of the non-priority device cannot be accepted on the operation pad 20 side, it is possible to appropriately limit the operation of the non-priority device after the above difference becomes zero. it can.

<< Other Embodiments >>
In the above embodiments, the power distribution system and the power distribution method of the present invention have been mainly described. However, the above embodiment is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.

  In the above embodiment, the power supply source to the power consuming device in the house H is only the commercial power supply CP. However, the present invention is not limited to this. As a power supply source, in addition to the commercial power supply CP, a power generation mechanism that generates power using natural energy such as solar energy, and a storage battery that stores power and discharges it as necessary However, the present invention is also applicable.

  In the above embodiment, the smart meter 3 is installed, and the upper limit of the power consumption of the entire house H in the current month is set to an amount corresponding to the prepaid power usage fee. . However, it is not limited to this, and there is no upper limit for the normal form, that is, the power consumption of the entire house H in the current month, and the amount of power used according to the cumulative amount of power consumption in the current month. The present invention is applicable even if the payment is made after the end of the current month.

  Further, in the above embodiment, a measuring device (CT sensor 4 in the above embodiment) for measuring the power consumption is provided for each of the power consuming devices in the house H. However, the present invention is not limited to this, and a measuring device is installed to measure at least the power consumption of the non-priority device among the priority devices and non-priority devices that are power consuming devices installed in the house H. It is good to be. For non-priority devices, this is a device whose power consumption can be reduced by reviewing the driving situation by the user's energy-saving behavior, so at least the power consumption of non-priority devices among the priority devices and non-priority devices This is because monitoring is necessary.

  Furthermore, in the above embodiment, a measuring device (smart meter 3 in the above embodiment) for measuring the power consumption of the entire house H is provided separately from the measuring device for each power consuming device. did. However, it is not limited to this, and the power consumption of the entire house H is not measured by installing a separate measurement device, but the measurement results of the measurement devices installed for each power consumption device are aggregated. And it is good also as making it the electric power consumption of the whole house H.

  Further, in the above-described embodiment, for the power consumption of each power consuming device installed in the house H, the cumulative amount from the start time of the current month to the execution time of the latest measurement data acquisition process is calculated, and the house H Regarding the overall power consumption, the cumulative amount during the same period was calculated. However, the present invention is not limited to this, and a cumulative amount of power consumption actually consumed by at least the non-priority device in the period may be calculated. That is, it is not necessary to calculate the cumulative amount of power consumption of the priority device and the entire house H.

  In the above embodiment, the total target amount of power consumption of the entire house H and the target amount of power consumption of each power consuming device are set based on a user input operation performed through the operation pad 20. did. However, the present invention is not limited to this, and, for example, the home server 2 may be set automatically (not based on a user input operation) with reference to past power consumption.

In the above embodiment, as an example of the power distribution system of the present invention, the system that distributes power based on the difference between the target amount of power consumption and the cumulative amount of actual power consumption has been described. As the power distribution system according to the present invention, not only the power consumption but also a system that manages not only the power consumption but also the power consumption (the amount of work that current flows per unit time) can be considered.
When describing such a system, first, a target upper limit value of power consumption in the entire house H is set, and then a target upper limit value is set for each power consuming device. At this time, the total target upper limit value of each power consuming device is set so as not to exceed the target upper limit value of power consumption in the entire house H. Then, the power distribution is temporarily interrupted for power consuming devices (especially non-priority devices) whose actual power consumption exceeds the target upper limit value. According to such a system, power can be systematically and rationally distributed to each power consuming device in the house H while optimizing both the power consumption and the power consumption in the entire house H. In other words, in the above system, a certain power consuming device (specifically, a non-priority device) consumes excessive power, causing a breaker to fall and other power consuming devices (specifically, priority devices). A problem that power is not supplied can be prevented.
