A distribution board 20 is provided in the body.

[Embodiment]
First, an example of a measurement system 1 according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a measurement system according to the embodiment.

[Measurement system]
As shown in FIG. 1, the measurement system 1 includes a power meter 10, a distribution board 20, an electric device LD, a controller CT, and a user terminal UT. The distribution board 20 includes a main breaker 30, a plurality of branch breakers 40a to 40b, a router 50, an HGW (Home Gate Way) 60, and a measuring device 100. In the example shown in FIG. 1, the power supply wiring is indicated by a solid line, and the wired or wireless communication path capable of transmitting and receiving information is indicated by a dotted line. In addition, the connection relationship of each structure of the measurement system 1 is not restricted to the connection relationship shown in FIG. 1, and may be another connection relationship. For example, information may be transmitted and received between components connected by a solid line, or an electrical connection relationship may be established between components connected by a dotted line. In the following description, it is assumed that the measurement system 1 is installed in a home.

  The power meter 10 is a meter that measures power supplied from a predetermined power system CP. For example, the power meter 10 is installed outside the house and measures the total amount of power consumed by the electric equipment LD such as a home appliance installed in the house. Thus, the total amount of power measured by the power meter 10 is, for example, the amount of power purchased from the power system CP side.

  The distribution board 20 is a device that divides electricity into wiring that supplies power to the electric device LD. For example, the distribution board 20 is supplied with power from the power system CP via a main wiring that is a main power supply wiring. In addition, the distribution board 20 branches the main wiring into a plurality of branch wirings, and distributes the electric power supplied via the main wiring to each branch wiring. And the distribution board 20 supplies the electric power distributed to each branch wiring to each electric equipment LD installed in each room in the house. For example, the distribution board 20 includes a branch wiring that supplies power to the electrical equipment LD installed in the living room, a branch wiring that supplies power to the electrical equipment LD installed in the kitchen, and an electrical equipment LD installed in the bathroom. Power is supplied to a branch wiring that supplies power to the cable. In the following description, the main wiring and each branch wiring may be collectively referred to as “each wiring” in some cases.

  The main breaker 30 is an earth leakage circuit breaker or a circuit breaker arranged in the main wiring. For example, in the main breaker 30, a maximum value of the amount of current flowing through the main wiring is set in advance according to the power purchase contract, the amount of power allowed by the home wiring, and the like. Then, when the amount of current flowing through the main wiring exceeds a preset maximum value, the main circuit breaker 30 opens the connection of the main wiring and supplies power to the electrical equipment LD in order to prevent leakage. Shut off.

  The branch breakers 40a to 40c are a plurality of earth leakage breakers or wiring breakers arranged in each branch wiring. In the following description, branch breakers 40a to 40c may be collectively referred to as “branch breaker 40”. For example, in the branch breaker 40, the maximum amount of current flowing through the branch wiring is set in advance according to the amount of power allowed by the wiring of each branch wiring, and the amount of current flowing through the branch wiring is set in advance. If the maximum value is exceeded, the connection of the branch wiring is released, and the power supply to the electric equipment LD connected to the branch wiring is cut off.

  In the example illustrated in FIG. 1, the three branch breakers 40 a to 40 c are described. However, the embodiment is not limited to this, and the measurement system 1 includes an arbitrary number of branch breakers 40. Good. Moreover, the measurement system 1 does not need to have the branch breaker 40 in every branch wiring, and may have the branch breaker 40 which interrupts | blocks branch wiring by arbitrary granularity, such as one or several branch wiring. In the following description, the main breaker 30 and the branch breaker 40 may be collectively referred to as “respective breakers 30 and 40”.

  The router 50 is a router device that is connected to the external network NT through an optical line or the like and relays between the measurement system 1 installed in the house and the external network NT. In addition to the measurement system 1, the router 50 may relay various networks installed in the home and the external network NT.

  The HGW 60 is a gateway device that converts a communication protocol when communicating with the measurement system 1 and the external network NT. For example, the HGW 60 relays various communications between the external server SV and the measurement device 100, the electric device LD, and the controller CT included in the measurement system 1. Here, in the measurement system 1 shown in FIG. 1, the router 50 and the HGW 60 are installed in the casing of the distribution board 20, and have a function of relaying communication between the home network and the external network NT. That is, the distribution board 20 has not only a function as a distribution board that distributes power but also a function as a router device and a gateway device. Further, power is supplied to the router 50 and the HGW 60 from the primary side of the main breaker 30, and electric power is supplied even when the main breaker 30 is cut off. It should be noted that the power line connecting the primary side of the main breaker 30 to the router 50 and the HGW 60 has a protection circuit such as a breaker that cuts off the conduction of the power line in order to protect the power line when a failure occurs in the router 50 or HGW 60 May be connected. With this configuration, even if the main breaker 30 is shut off, a PC or a portable terminal equipped with a battery can communicate with the server SV via the router 50 and also with the HGW 60. Similarly, the measuring device 100 may be supplied with power.

  The measuring device 100 is a measuring device that measures the amount of power supplied through the breakers 30 and 40, that is, the amount of power supplied through the main wiring and the branch wiring. For example, the measuring device 100 collects information (for example, a current value) indicating the amount of current from the current measuring device installed before and after each breaker 30, 40 or in each breaker 30, 40, and based on the collected information. Thus, the amount of electric power supplied via each breaker 30, 40 is specified. In the example illustrated in FIG. 1, the measuring device 100 collects the values of currents that flow to the electrical system CP side of the breakers 30 and 40, but the embodiment is not limited to this. That is, the measuring device 100 may measure the amount of power in an arbitrary manner as long as the amount of power supplied via the breakers 30 and 40 can be appropriately measured.

  In addition, the measuring device 100 notifies the controller CT of the measured electric energy via the HGW 60. The controller CT is a control device that controls the electric device LD and the home measurement system 1. For example, the controller CT has a function of displaying the amount of power measured by the measuring device 100, the power consumption of the electric device LD, the setting content of the electric device LD, and the like.

  The user terminal UT is a terminal device used by a user of the measurement system 1 and is, for example, a mobile terminal device such as a PC (Personal Computer), a smartphone, or a tablet. Note that the user terminal UT may be connected to the measurement network 1 via an external network NT such as a mobile communication network.

  Note that the measurement system 1 may have a configuration other than the configuration shown in FIG. For example, the measurement system 1 may include a storage battery that supplies electric power used in the house and a power generation device such as a photovoltaic panel.

[Measurement processing]
Here, when an electric leakage occurs or when the amount of power supplied exceeds a predetermined threshold due to the use of the electric device LD, the breakers 30 and 40 cut off the power supply. When each of the breakers 30 and 40 cuts off the power supply, the user goes to the vicinity of the distribution board 20 and manually selects a breaker (so-called broken breaker) that cuts off the power supply among the breakers 30 and 40. The power supply is resumed by operating. For this reason, when it is not known which breaker cut off the power supply, it is difficult to restart the power supply.

  In addition, if a leakage occurs, the power supply cannot be resumed even if the breaker is manually operated. However, if the power supply is interrupted due to the use of the electric device LD, the electric device LD The power supply can be resumed by operating the breaker after the use is stopped. However, it is difficult to specify whether a leakage has occurred when the power supply is cut off or whether the power supply is cut off with the use of the electric device LD.

  Therefore, the measurement system 1 executes measurement processing. First, the measurement system 1 collects information indicating the amount of current flowing through each of the breakers 30 and 40 (hereinafter sometimes referred to as “current amount”). And the measurement system 1 outputs the information regarding the interruption | blocking of the electric power supply based on the collected information (Hereinafter, it may be described as "the interruption | blocking information.").

  For example, when an electric leakage occurs, the amount of current flowing through the main wiring and the branch wiring closer to the main wiring than the location where the electric leakage occurs increases rapidly, and then the power supply is cut off. On the other hand, when the electrical equipment LD is used more than prescribed, the amount of current flowing through the main wiring and each branch wiring gradually increases with the use of the electrical equipment LD, and exceeds the preset maximum value. After this state continues, the power supply is cut off. In addition, when the use of all the electric devices LD is finished, it is considered that the amount of current flowing through each wiring gradually decreases.

  Therefore, the measuring device 100 determines whether an electric leakage has occurred or whether the electric device LD is used more than specified according to a change in the amount of current measured until the power supply is cut off. In addition, the measuring device 100 identifies the breaker that has cut off the power supply.

  For example, in the measuring instrument 100, when the amount of current flowing through the main line increases rapidly and then the amount of current flowing through the main line changes rapidly to “0”, a leakage occurs, and the main breaker 30 It is determined that the power supply has been cut off. In addition, when the amount of current flowing through the main wiring gradually increases and then the amount of current flowing through the main wiring rapidly changes to “0”, the measuring device 100 causes a main circuit breaker to be used along with the use of the electric device LD. It is determined that 30 has cut off the power supply.

  On the other hand, in the measuring instrument 100, the amount of current flowing through one of the branch lines increases rapidly, and then the amount of current flowing through the branch line does not become “0” but the amount of current flowing through the branch line becomes “0”. In the case of a sudden change, it is determined that a leakage has occurred and the branch breaker 40 installed in the branch wiring has cut off the power supply. In the measuring instrument 100, the amount of current flowing through one of the branch wirings gradually increases, and thereafter, the amount of current flowing through the main wiring is not “0”, but the amount of current flowing through the branch wiring is “0”. If the electric power supply LD is used, it is determined that the branch breaker 40 installed in the branch wiring has cut off the power supply.

  As described above, the measuring device 100 is configured to determine whether or not a leakage has occurred, whether or not the power supply is interrupted due to the use of the electric device LD, and whether the breaker that has cut off the power supply corresponds to the change in the current amount. Identify which breakers are. And the measuring device 100 outputs the information which shows specific content to the user terminal UT and controller CT as interruption | blocking information. As a result, when the power supply is cut off, the user determines whether or not a leakage has occurred, whether or not the power supply is cut off due to the use of the electric device LD, and the breaker that cuts off the power supply You can recognize which breaker. For this reason, the user can easily restore the power supply.

[Information provision processing]
In the processing described above, the measuring device 100 outputs the cutoff information when the cutoff of the power supply by the main breaker 30 or the branch breaker 40 occurs. However, the embodiment is not limited to this. For example, even if the power supply is not actually cut off, the measuring device 100 may output various types of information that can be information for preventing the occurrence of the power supply cut-off as the cut-off information.

  For example, the measuring device 100 continuously measures the amount of current flowing through the main wiring and the branch wiring, and based on the measured current amount, the current measured in a predetermined period (for example, every few hours or the same day). Specify the maximum instantaneous value. And the measuring device 100 may output the specified maximum instantaneous value and the time zone when the maximum instantaneous value was measured as the cutoff information. Here, the measuring device 100 may output the maximum instantaneous value and the time zone when the maximum instantaneous value is measured for each main wiring and branch wiring.

  In addition, the measuring device 100 generates advice on the use of power based on the difference between the amount of current that the main breaker 30 cuts off the power supply and the amount of current that flows through the main wiring. For example, the measuring device 100 calculates the difference between the amount of current that the main breaker 30 cuts off the power supply and the amount of current that flows through the main wiring for each time period, and the margin until the main breaker 30 cuts off the power supply A time zone in which is below a predetermined threshold is specified. And the measuring device 100 may produce | generate the advice which shows that there is no remaining power until the main breaker 30 interrupts | blocks electric power supply in the specified time slot | zone, and may output the produced | generated advice.

  In addition, the measuring device 100 specifies a time period in which a margin until the branch breaker 40 that supplies power to the electric device LD installed in the living room cuts off the power supply is equal to or less than a predetermined threshold, for example. And the measuring device 100 may output the advice that there is no remaining power until the power supply to the living room is cut off in the specified time zone. Moreover, the measuring device 100 may specify a time zone in which there is no remaining power until the power supply is cut off by the breakers 30 and 40 from the history of the measured electric energy, and may output advice indicating the specified time zone.

  Each of the breakers 30 and 40 cuts off the power supply when the amount of current flowing through the wiring exceeds a predetermined threshold value, but the power consumption is often described in the electric device LD used by the user. For this reason, the measuring device 100 may output an advice indicating the margin until the breakers 30 and 40 cut off the power supply, not the amount of current but the amount of power.

  For example, it is assumed that the amount of current flowing through the main wiring in a certain time zone is “25 A (ampere)”. In addition, the main breaker 30 cuts off the power supply when a current of “30 A” flows through the main wiring. Further, it is assumed that the voltage applied to the main wiring is “100 V (volts)”. In such a case, the measuring device 100 calculates a margin until the main breaker 30 cuts off the power supply in that time zone as “100 V × (30−25) A = 500 W (watts)”. And the measuring device 100 outputs the advice that the allowance until the main breaker 30 interrupts | blocks an electric power supply in the time slot | zone is "500W" as interruption | blocking information.

[Configuration example of measuring equipment]
Next, the configuration of the measuring device 100 will be described with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of the measurement device according to the embodiment. As illustrated in FIG. 2, the measuring device 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

  The communication unit 110 is realized by a predetermined communication circuit, for example. For example, the communication unit 110 relays communication with the HGW 60. In addition, when the communication unit 110 receives information indicating the amount of current from current measuring devices installed before and after each of the breakers 30 and 40 or in the breaker, the communication unit 110 transmits the received information to the collection unit 131.

  The storage unit 120 is realized by, for example, a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. As illustrated in FIG. 2, the storage unit 120 according to the embodiment includes a history storage unit 121 and a breaker information storage unit 122.

  The history storage unit 121 stores history information indicating the history of the amount of power supplied via the breakers 30 and 40. For example, FIG. 3 is a diagram illustrating an example of information stored in the history storage unit according to the embodiment. As illustrated in FIG. 3, information having items such as “breaker information”, “measurement time”, and “power consumption (W)” is registered in the history storage unit 121. Here, “breaker information” is information indicating a breaker that supplies power. The “measurement time” is information indicating the time when the amount of power is measured. “Power consumption (W)” is information indicating the measured power consumption.

  For example, in the example illustrated in FIG. 3, the history storage unit 121 indicates that “2800” watts of power was being supplied when the “main breaker” was “2015/11/30/12: 00”. Information, “Master trunk breaker” is “2015/11/30/12: 01”, information indicating that “3000” watts of power was supplied, “Master trunk breaker” is “2015/11/30 / Information indicating that the power of “2500” watts was supplied at the time of “12:02” is registered.

  The breaker information storage unit 122 stores information on the breakers 30 and 40 included in the measurement system 1. For example, FIG. 4 is a diagram illustrating an example of information registered in the breaker information storage unit according to the embodiment. As shown in FIG. 4, information having items such as “breaker information”, “supply position”, and “capacity” is registered in the breaker information storage unit 122. Here, the “supply position” is information indicating the position in the house where power is supplied through the breaker indicated by the associated “breaker information” such as “main trunk wiring”, “kitchen”, “living room”, etc. is there. The “capacity” is the amount of current allowed by the breaker indicated by the associated “breaker information”. When a current exceeding this amount of current flows, the power supply is cut off.

  For example, in the example shown in FIG. 4, power is supplied to the breaker information storage unit 122 when the “main trunk breaker” supplies power to the “main trunk wiring” and an amount of current exceeding “30 A” flows. Information to block is registered. Further, in the example shown in FIG. 4, power is supplied to the breaker information storage unit 122 when “branch breaker # 1” supplies power to “kitchen” and an amount of current exceeding “10 A” flows. Information indicating that the supply is shut off is registered. Further, in the example shown in FIG. 4, power is supplied to the breaker information storage unit 122 when “branch breaker # 2” supplies power to “living” and an amount of current exceeding “15 A” flows. Information indicating that the supply is shut off is registered.

  Returning to FIG. 2, the description will be continued. The control unit 130 has an internal memory for storing a program that defines various processing procedures and the necessary data, and executes various processes by using these programs. Particularly, as closely related to the present invention, A collection unit 131, a determination unit 132, and an output unit 133 are included.

  The collection unit 131 collects information indicating the amount of current supplied through each of the breakers 30 and 40 that cuts off the power supply when the amount of current flowing through the wiring exceeds a predetermined value. For example, the collection unit 131 acquires information indicating the amount of current from a current measurement device that measures the amount of current flowing through each wiring at predetermined time intervals. Then, the collection unit 131 determines the value of the amount of power supplied through each wiring, that is, each breaker 30 based on the information indicating the acquired current amount and the value of the voltage applied to each wiring in the house. , 40 is calculated as the power consumption. Thereafter, the collection unit 131 registers the breaker information of each of the breakers 30 and 40, the measurement time when the current amount is measured, and the calculated power consumption value in association with each other in the history storage unit 121.

  The determination unit 132 determines whether or not a leakage has occurred based on the collected information. For example, the determination unit 132 refers to the power consumption value registered in the history storage unit 121 and determines whether or not a leakage has occurred based on a change in the power consumption value. To describe a more specific example, the determination unit 132 extracts a transition of power consumption for each breaker information every time a new power consumption value is registered in the history storage unit 121, and the transition of the extracted power consumption Based on the above, the breaker that cuts off the power supply is identified.

  For example, the determination unit 132 identifies all breakers whose power consumption calculated last time is larger than a predetermined threshold among the breakers whose new power consumption is “0”. More specifically, the determination unit 132 extracts the “capacity” value of the breaker whose new power consumption is “0” from the breaker information storage unit 122, and the previously calculated power consumption is the breaker information storage unit. All breakers that exceed the value extracted from 122 are identified.

  And the determination part 132 specifies the breaker installed in the position nearest to the electric power grid | system CP among the identified breakers, ie, the breaker arrange | positioned most upstream, as a breaker which interrupted | blocked electric power supply. For example, when the determination unit 132 identifies the main breaker 30 and the plurality of branch breakers 40, the determination unit 132 identifies the breaker installed at a position closest to the power system CP, that is, the main breaker 30 as a breaker that cuts off the power supply. To do.

  Moreover, the determination part 132 extracts the transition of the power consumption in the specified breaker, when the breaker which interrupted | blocked electric power supply is specified. Then, the determination unit 132 determines whether or not a leakage has occurred at a location in the house where power is supplied via the specified breaker, based on the transition of power consumption in the specified breaker.

  For example, FIG. 5 is a diagram illustrating an example of processing executed by the determination unit according to the embodiment. In the example shown in FIG. 5, an example of the transition of power consumption when the power supply is cut off with the use of the electric device LD, and the power consumption when the power supply is cut off due to the occurrence of electric leakage. An example of transition was described.

  For example, as shown in FIG. 5A, when the power supply is cut off with the use of the electric device LD, the power consumption gradually increases with time, and is shown in FIG. As described above, the power consumption transitions to “0” after the power consumption exceeds the predetermined threshold “L” and the time has elapsed. For this reason, as shown in (A) of FIG. 5, the determination unit 132 is accompanied by the use of the electric device LD when the power consumption gradually changes to “0” after gradually increasing. Then, it is determined that the power supply is cut off with the use of the electric device LD.

  On the other hand, as shown in FIG. 5C, when the power supply is interrupted due to the occurrence of a leakage, as shown in FIG. 5D, the power consumption suddenly increases to a predetermined threshold “L”. After that, the power consumption rapidly changes to “0”. For this reason, as shown in (C) of FIG. 5, when the power consumption has suddenly increased and the power has suddenly changed to “0”, the determination unit 132 determines that the power It is determined that the supply has been cut off.

  Note that the process for identifying the breaker that cuts off the power supply, the process for determining whether or not a leakage has occurred, and the process for determining whether or not the power supply has been cut off in accordance with the specifications of the electrical equipment LD are described above. It is not limited to processing. That is, the measuring device 100 may specify a breaker that cuts off the power supply using any technique, whether or not a leakage has occurred, or whether or not the power supply is cut off according to the specifications of the electric device LD. It may be determined.

  In the above description, the determination unit 132 determines whether there is a breaker that interrupts power supply or leakage, based on the amount of power consumption registered in the history storage unit 121. However, the embodiment is not limited to this. It is not limited. For example, the determination unit 132 may determine the presence or absence of a circuit breaker that has cut off the power supply, a leakage, or the like based on the value of the current amount collected by the collection unit 131.

  Returning to FIG. 2, the description will be continued. The output unit 133 outputs blocking information based on the information collected by the collection unit 131. For example, the output unit 133 outputs information indicating a breaker that has cut off the power supply as the cutoff information. Moreover, the output part 133 outputs the information which shows generation | occurrence | production of an electrical leakage as interruption | blocking information, when the determination part 132 determines with the electrical leakage having generate | occur | produced.

  For example, when the determination unit 132 identifies a breaker that cuts off the power supply, the output unit 133 identifies the position where the identified breaker is set, such as the position in the distribution board 20 that has cut off the power supply. Is output to the controller CT and the user terminal UT, and the output information is displayed. To describe a more specific example, the output unit 133 may output blocking information such as “Please raise the second breaker from the right”.

  Further, when it is determined by the determination unit 132 that a leakage has occurred, the output unit 133 indicates the position in the house where power is supplied by the breaker that has cut off the power supply, that is, the “supply position”, as the breaker information storage unit 122. May be displayed on the controller CT or the user terminal UT to indicate that leakage has occurred at the extracted position.

  Similarly, when the output unit 133 determines that the power supply has been cut off due to the use of the electric device LD, the output unit 133 similarly has a position in the house where power is supplied by the breaker that cuts off the power supply, that is, the “supply position”. Is extracted from the breaker information storage unit 122. Then, the output unit 133 may cause the controller CT and the user terminal UT to display information that proposes to refrain from using the electrical device LD at the extracted position.

  As described above, when the power supply is interrupted by the breakers 30 and 40, the output unit 133 is configured to interrupt the power supply, the position in the house where the power supply is interrupted, and the reason why the power supply is interrupted. Is identified. And the output part 133 outputs the information containing specific content as interruption | blocking information. In addition to the above information, the output unit 133 may output information such as the time when the power supply interruption occurs as the interruption information.

  Further, the output unit 133 outputs information regarding the maximum value of the current flowing through the wiring within a predetermined period as the cutoff information. Further, the output unit 133 outputs advice on the use of power based on the difference between the amount of current flowing through the wiring and a predetermined value at which each breaker 30 or 40 cuts off the power supply as the cut-off information. That is, the output unit 133 outputs information indicating a margin until the power supply is cut off, information for preventing the power supply cut-off, and the like even if the power supply is not cut off.

  For example, the output unit 133 refers to the history storage unit 121 at a predetermined time every day, and specifies the maximum value of the power supplied by the main breaker 30 on the day and the time when the value is measured.

Next, the flow of measurement processing in the measurement system 1 will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of measurement processing by the user according to the embodiment. For example, the measuring device 100 collects power values indicating the amounts of power supplied by the breakers 30 and 40 (step S101). Subsequently, the measuring device 100 determines whether or not power interruption has occurred (step S102). And when the interruption | blocking of electric power has not generate | occur | produced (step S102: Yes), the measuring device 100 performs step S101 again.

  On the other hand, when the interruption occurs (step S102: Yes), the measuring device 100 identifies the interruption point where the interruption of electric power, that is, the breaker that interrupted the electric power (step S103). In addition, the measuring device 100 identifies the interruption content such as whether or not a leakage has occurred, whether or not the power supply has been cut off as the electric device LD is used (step S104). Then, the measuring device 100 outputs blocking information including the specified blocking location and blocking content to the controller CT and the user terminal UT (Step S105), and ends the process.

[Information provision processing flow]
Next, the flow of information provision processing in the measurement system 1 will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of information providing processing by the user according to the embodiment. For example, the measuring device 100 determines whether it is the advice output timing (step S201). For example, the measurement device 100 determines that it is the advice output timing when the user requests the advice output or when a predetermined time is reached. If it is not the advice output timing (step S201: No), the measuring device 100 waits until the output timing.

  If it is the advice output timing (step S201: Yes), the measuring device 100 acquires the history of the power supplied by each of the breakers 30 and 40 (step S202), and generates the advice based on the acquired history. (Step S203). More specifically, the measuring instrument 100 generates various advices based on the time period during which each breaker 30, 40 supplied the most power and the margin until each breaker 30, 40 cuts off the power supply. To do. Then, the measuring device 100 outputs the generated advice to the controller CT and the user terminal UT (Step S204), and ends the process.

[Execution subject]
In the above description, the measurement process and the information providing process are realized by the measurement device 100 installed in the distribution board 20. However, the embodiment is not limited to this. For example, the measuring device 100 may be a device installed independently of the distribution board 20. Various functions exhibited by the measuring device 100 may be realized by the HGW 60, the controller CT, and the user terminal UT. For example, the distribution board 20 has only the function exhibited by the collection unit 131, and the functions performed by the determination unit 132 and the output unit 133 are executed by the HGW 60, the controller CT, and the user terminal UT. It may be realized with.

  Further, the function exhibited by the measuring device 100 may be realized by, for example, an external server SV installed outside the measurement system 1. That is, the above-described measurement process and information providing process may be realized by any device installed in the house or any device installed outside the house alone or in cooperation.

[advice]
Moreover, the measuring device 100 may output arbitrary advice in addition to the various advices described above. For example, the measuring device 10 may output various advices based on the power consumption history registered in the history storage unit 121. To give a more specific example, the measuring device 10 is based on the power consumption history registered in the history storage unit 121, so that the time until the breakers 30 and 40 are likely to close up the power supply is tight. It is also possible to output advice indicating that the electric device LD is not used in the specified time zone.

  In addition, the measuring device 100 may output advice indicating a position or time zone in the home where a margin until the power supply is cut off is likely to be tight. For example, the measuring device 100 may provide advice such as “the kitchen power is tight from 7 pm to 8 pm”, advice such as “the living room power is tight from 5 pm to 6 pm”, “8 pm From 9 o'clock to 9 o'clock, since the power in the house is tight, let's output advice such as “Let's reduce power consumption”.

  Note that the measuring device 100 may collect the operation state of each electric device LD via the HGW 60 and output advice based on the collected operation state. For example, the measuring device 100 is, for example, an electric device LD that consumes a large amount of power, such as a microwave oven and a toaster, among the electric devices LD installed in the kitchen, where the margin of a breaker that supplies power to the kitchen is tight. May be output, such as “Let's refrain from using a microwave oven and a toaster”.

  In the above description, the measuring device 100 outputs advice when there is a request from the user or at a predetermined timing. However, the embodiment is not limited to this. For example, the measuring device 100 determines whether or not the margin for shutting off the power supply of the breakers 30 and 40 is tight, and if not tight, does not output advice and tightly Advice may be output only if That is, the measuring device 100 determines whether or not to output advice according to a margin until the power supply to each breaker 30 and 40 is cut off, a history of power consumption, and the like, and determines that the advice is to be output.
