In recent years, in order to encourage power consumers to improve their power saving awareness, they have measured electricity consumption of electrical devices used in their homes, and provided with a management device that notifies power consumers of the measurement results A device management system has been proposed.
In addition, as a technique used in such a system, for example, as described in Non-Patent Document 1, for example, by measuring a voltage / current waveform at an outlet of an outlet provided in a home, There is a technology to identify the type of electrical equipment that is used.

George W Hart “Nonintrusive Appliance Load Monitoring” [online], [March 27, 2012 search], Internet <http://georgehart.com/research/nalm.html>

In order to identify the type of electrical equipment used in the home by measuring the voltage / current waveform as described above, the voltage consumed at each outlet of the multiple outlets installed in the home・ It is necessary to measure the current and acquire the waveform data. For this purpose, a sensor capable of detecting a voltage / current with a high-speed sampling cycle and an arithmetic unit for processing the detection result at high speed are required at each insertion port.
However, such high-performance sensors and computing units are expensive, and more than one outlet (insertion port) is generally provided in the house. If an arithmetic unit is provided, the entire system becomes very expensive.

  For this reason, for example, it is conceivable to install a central device that collects and manages data obtained from the outlets of the outlets in the home, and to provide the central device with a function for specifying the type of electrical equipment. In this case, the waveform data of the voltage / current measured at each insertion port may be transmitted to the central device.To this end, a sensor capable of detecting the voltage / current with a high-speed sampling cycle is provided at each insertion port. In addition, a communication device capable of transmitting a large amount of information acquired at a high-speed sampling cycle is required, and the entire system becomes expensive.

  In addition, by measuring the voltage and current waveforms on distribution boards that distribute power to multiple outlets (plugs) in the home, the type of electrical equipment connected to these plugs is specified. I think it can be done. However, in this case, it cannot be determined to which insertion port the electrical device whose type is specified is connected.

  Therefore, the present invention makes it possible to grasp the usage status of what kind of electrical equipment is connected to which outlet of the outlet and power is consumed, and this can be done at low cost. It aims to be feasible.

(1) The electrical equipment management system of the present invention is consumed by all of the electrical equipment connected to the outlets of a plurality of outlets that measure the grid power grid side from the distribution board and distribute power from the distribution board. A measurement unit for acquiring information on the power to be detected, and the type of the electrical device connected to the insertion port based on the information, and the type of the specified electrical device and each of the specified electrical device Acquisition that identifies and acquires, for each insertion port, specific information that generates specific information that indicates power consumption and individual information that indicates individual power consumption consumed by the electrical devices connected to each of the insertion ports. And a discriminating unit that discriminates an insertion port that is a connection destination of the electrical device whose type is specified by the specifying unit based on the specifying information and the individual information. And wherein the door.

According to the present invention, by identifying the outlet of the outlet that is the connection destination of the electric device whose type is specified by the specifying unit, what type of electric device is connected to which outlet and power is consumed. It becomes possible to grasp the usage situation about what is being done.
In the present invention, the information used by the specifying unit to specify the type of electrical equipment connected to the outlet is not acquired for each outlet, but the power grid side is measured from the distribution board. Acquired by targeting. For this reason, it is not necessary to provide a high-function device that performs processing at a fine sampling cycle in order to specify the type of electric device for each outlet, and it is only necessary to provide it from the distribution board to the grid power network side. It becomes possible to contribute to cost reduction.

(2) Moreover, the measurement unit measures the measurement target at a first sampling period, and the acquisition unit acquires the individual information at a second sampling period larger than the first sampling period. Is preferred.
(3) In particular, the first sampling period is preferably 10 microseconds or more and 1 millisecond or less, and the second sampling period is preferably 1 second or more and 60 seconds or less.
In this case, the measuring unit that measures the grid power grid side from the distribution board requires a highly functional device that performs processing in a fine first sampling period.
On the other hand, an acquisition part should just acquire individual information with a sampling period larger than this 1st sampling period. Therefore, it is only necessary to measure and transmit individual power consumption with a large sampling period on the outlet side of the outlet that is the source of this individual information, and it is a highly functional device that performs processing with a fine sampling period. Etc. need not be provided for each insertion port. Therefore, even if there are a plurality of outlets (inserts), it is possible to prevent the entire system from becoming costly.

(4) Moreover, the measurement unit measures the measurement target at a first sampling period, and the identification unit generates the identification information at a third sampling period larger than the first sampling period. Is preferred.
In this case, the measuring unit that measures the grid power grid side from the distribution board requires a highly functional device that performs processing in a fine first sampling period.
On the other hand, the identification unit may generate the identification information with a third sampling period that is larger than the first sampling period. For this reason, in a specific part, the highly functional apparatus like a measurement part becomes unnecessary, and it can hold down cost.

(5) Further, each of the individual information and the specific information includes information indicating a measurement time of power consumption, and the determination unit includes a time when the power consumption indicated by the individual information changes, It is preferable to determine the insertion port that is the connection destination of the electric device whose type is specified by the specifying unit by comparing the time when the power consumption amount indicated by the specifying information is changed.
In this case, the time when the power consumption amount indicated by the individual information changes matches the time when the power consumption amount indicated by the specific information matches, so that the specified electrical device is connected to which outlet. It becomes possible to grasp the usage situation about whether there is.

(6) Furthermore, in the electrical equipment management system according to (5), the determination unit collates the power consumption amount indicated by the specific information with the power consumption amount indicated by the individual information. Thus, it is preferable to determine the insertion port that is the connection destination of the electrical device whose type is specified by the specifying unit.
In this case, further, the power supply amount indicated by the individual information matches the power consumption amount indicated by the specific information, and which plug is connected to the specified electrical device. It becomes possible to grasp the use situation about.

(7) Furthermore, the electrical equipment management system measures the individual power consumption of the electrical outlet connected to the electrical outlet connected to the electrical outlet connected to the electrical outlet connected to the electrical outlet and the measured result. It is preferable to further include an outlet device that includes a communication unit that transmits the information to the acquisition unit in association with the identification information of the insertion port.
In this case, an electrical equipment management system including an outlet device is configured.
Then, in this way, the measurement result is associated with the identification information of the outlet of the outlet and transmitted from the communication unit to the acquisition unit, so that the acquisition unit is connected by the electrical device connected to each of the insertion ports. It becomes possible to identify and acquire individual information indicating individual power consumptions for each insertion slot.

(8) Moreover, the electrical equipment management method of the present invention is based on all the electrical equipment connected to the outlets of a plurality of outlets that are subject to measurement from the distribution board to the grid power network side and are divided from the distribution board. Acquires information on the power consumed, identifies the type of electrical equipment connected to the outlet based on the information, and identifies the type of electrical equipment identified and the power consumption of each of the identified electrical equipment Specific information indicating the individual power consumption amount consumed by the electrical equipment connected to each of the outlets is identified and acquired for each outlet, and the specific information and the individual Based on the information, the insertion port that is the connection destination of the electrical device whose type is specified is determined.
According to the present invention, it is possible to achieve the same effects as the electrical equipment management system described in (1).

  According to the present invention, by identifying the outlet of the outlet that is the connection destination of the electric device whose type is specified, what type of electric device is connected to which outlet and power is consumed. It is not necessary to provide a high-functional device that performs processing at a fine sampling cycle for each electrical outlet, in order to identify the type of electrical device, It is possible to contribute to cost reduction.

Embodiments of the present invention will be described below.
[General configuration of electrical equipment management system]
FIG. 1 is an explanatory diagram of a house 2 in which an electrical equipment management system 1 according to the present invention is installed. The house 2 is supplied with power from the grid power network through the power line 3. A power meter 4 and a distribution board 5 are connected to the power line 3, and the power meter 4 manages the amount of power supplied from the grid power network. The distribution board 5 has a main circuit breaker 5 a and sub circuit breakers 5 b and 5 c, and each of the sub circuit breakers 5 b and 5 c is connected to outlets 6 and 7 installed in the house 2.

  An identification number (outlet ID) is set for each outlet, and the first outlet 6 with the outlet ID “001” has three insertion ports 6a, 6b, and 6c. The second outlet 7 that is “002” has three insertion ports 7a, 7b, and 7c. As described above, power is supplied from the grid power network side to these insertion ports. The outlet 6 constitutes a first outlet device 30 together with a processor 31 (see FIG. 2) to be described later, and the outlet 7 has a second outlet device 40 together with a processor 41 (see FIG. 2) to be described later. Configure.

  The electrical equipment management system 1 includes a management device 10 and a measurement unit 20. In the present embodiment, the measurement unit 20 is installed in the distribution board 5, but may be installed outside the distribution board 5. The management device 10 is installed in the house 2 and is informed to a power consumer (resident of the house 2) based on information acquired at the measurement unit 20 and the outlets 6 and 7 (each outlet). It has a function to generate and output information.

[Outlet devices 30, 40]
FIG. 2 is a block diagram of the outlet device. The first outlet device 30 and the second outlet device 40 have the same configuration. Therefore, here, the first outlet device 30 will be described as a representative. The outlet device 30 includes an outlet 6 having three insertion ports 6a, 6b, and 6c, a processor 31 having a CPU and the like, a sensor unit 32, a relay control unit 33, a communication unit 34, and a memory 35. The processor 31 performs processing (calculation) for performing various functions according to the computer program stored in the memory 35.

  Electrical plugs (not shown) can be connected to the outlets 6a, 6b, 6c of the outlet 6, respectively. The sensor unit 32 measures the individual power consumption (wattage) of the electrical equipment connected to each of the outlets 6 a, 6 b, 6 c of the outlet 6. That is, although the three insertion openings 6a, 6b, and 6c are provided, the sensor unit 32 can individually measure the power consumption amount of the electrical equipment connected to each of the insertion openings 6a, 6b, and 6c.

  Further, insertion port identification information (insertion port ID) is set in each of the insertion ports 6a, 6b, and 6c. The identification information of the insertion openings 6a, 6b, and 6c is “00A”, “00B”, and “00C”.

  The processor 31 generates individual information X indicating the measurement result measured by the sensor unit 32. In addition, the information on the measurement result included in the individual information X is associated with the outlet ID and the insertion slot ID that are measured by the sensor unit 32. That is, when an electric device is connected to the outlet 6a of the outlet 6 and power is consumed, when the power consumption of the electric device is measured by the sensor unit 32, the measurement result is given to the outlet 6. The individual information X in which the outlet ID “001” and the outlet ID “00A” are associated is generated. The processor 31 and the sensor unit 32 have a clock function, and the individual information X includes information indicating the measurement time of the power consumption.

The sampling period Ta for measuring the power consumption by the sensor unit 32 is 1 to 60 seconds, and the period for generating the individual information X is also the same as this sampling period Ta.
The communication unit 34 includes an interface that performs information communication with the management apparatus 10, and transmits the individual information X generated by the processing of the processor 31 to the management apparatus 10. This transmission cycle may be the same as or different from the sampling cycle Ta. When this transmission cycle is different from the sampling cycle Ta, it is preferable to set the transmission cycle to be larger than the sampling cycle Ta. In this case, by collecting and transmitting individual information X (a plurality of measurement data) It becomes possible to reduce the communication load.

  As will be described later, the relay control unit 33 individually cuts off (off) the power supply of each of the insertion ports 6a, 6b, and 6c based on a command signal from the control command unit 18 (see FIG. 4) of the management device 10. Or return (turn on). For example, the relay control unit 33 can cut off the supply of power to the electrical device based on the command signal from the state where the electrical device is connected to the insertion opening 6a and power is consumed. The power supply to this electric device can be restored based on the above.

  As described above, the outlet device 30 can measure the individual power consumptions of the electrical devices connected to the outlets 6a, 6b, and 6c of the outlet 6, and the measurement result includes the outlet ID and the outlet ID. The individual information X associated with the insertion slot ID can be transmitted to the communication unit 12 of the management apparatus 10.

[Measurement unit 20]
FIG. 3 is a block diagram of the measurement unit 20. The measurement unit 20 includes a processor 21 having a CPU and the like, a communication unit 22, a sensor unit 23, and a memory 24. The processor 21 performs processing (calculation) for performing various functions according to the computer program stored in the memory 24. As a function executed by the processor 21, the measurement unit 20 can have a specifying unit 27 described later.
The communication unit 22 includes an interface that performs information communication with the management device 10, and transmits information (specific information Z) generated by the processing of the processor 21 to the management device 10.

The sensor unit 23 measures the power grid side from the distribution board 5 as a measurement target. That is, the sensor unit 23 measures the amount of electricity, voltage, current, and phase of electricity flowing through the power line 3. Then, the processor 21 generates information for identification including the measurement time of the voltage / current by the sensor unit 23 in the measurement result. In addition, since the electric energy etc. which the sensor part 23 measures are the electric energy etc. of the electricity which flows through the power line 3 (refer FIG. 1), the measured value is set to all the outlets 6 and 7 (all the insertion ports). The total amount of power consumed by all connected electrical devices.
In other words, the sensor unit (measuring unit) 23 is configured to obtain information on the power consumed by all the electrical devices connected to the outlets of the two outlets 6 and 7 that are divided from the distribution board 5 (specific information). ) Can be obtained.

Then, the identification unit 27 by the processor 21 performs processing for identifying the type of the electrical device that is connected to each of the outlets of the outlets 6 and 7 and consumes power based on the information for identification. This process is called “specific process (or identification process)”.
The specific process will be described. It is generally known that the waveform of electricity (current / voltage) consumed by an electrical device varies depending on the type of electrical device. Therefore, the specifying unit 27 acquires the feature of the waveform based on the specifying information, and specifies the type of the electric device based on the feature point.

The specific process will be described in detail. The memory 24 of the measurement unit 20 includes a database that associates various types of electrical equipment with the characteristics (features) of electricity consumed by each of the electrical equipment. . Note that an identifier is assigned to each type of electrical equipment in the database. The feature (feature value) includes a voltage value, a current value, and a phase difference.
When an electrical device is connected to the outlet of the outlet and consumes electric power (however, the outlet of the outlet is unknown), the electric current (current) flowing through the power line 3 is detected by the sensor unit 23. Voltage is sampled at a high speed (for example, 10 to 20 kHz), information for identification including the measurement result and measurement time is generated, and the identifying unit 27 includes a current value included in the information for identification, Features (features) specific to the electric device are extracted from the data such as the voltage value and the phase difference. Then, the specifying unit 27 compares the feature (feature amount) extracted from the information for specification with the feature (feature amount) in the database, thereby connecting the connected electrical device (electricity in the on state). Equipment).

  In addition, when a plurality of electric devices are connected to a plurality of insertion openings, electricity consumed by these electric devices flows through the power line 3 and the sensor unit 23 samples this. In this case, the features (features) of electricity consumed by these electric devices overlap, but the specifying unit 27 can identify them. For example, if a plurality of electrical devices are connected to the outlets of the outlets 6 and 7 at different times, current and voltage change at the connection start time. It is possible to identify them, and it is possible to specify the type of each of these electric devices. In addition, this specific process may be based on another method.

  In addition, the database in the memory 24 includes information on power consumption in addition to various types of electrical devices and characteristics (features) of electricity consumed by each of these electrical devices. It is accumulated corresponding to the kind of. Note that, as described above, the database includes the voltage value, current value, and phase difference of each electrical device as the feature amount. From these, the power consumption amount of each electrical device can be calculated.

Therefore, the specifying unit 27 can obtain the power consumption consumed by each specified electric device as follows.
In other words, the electric power consumption (in an on state) where the total power consumption (total power consumed by all electric devices) is obtained by the sensor unit 23 at each time. Can be determined by the specifying unit 27, the power consumption of the electrical equipment in the ON state can be obtained based on the information in the database.
In addition, even in the case of an electric device having another state other than the two states of on / off, the power consumption can be obtained in the same manner based on the information in the database. For example, in an electrical device, when there are three states of on (mode 1), on (mode 2), and off, the feature amount in the database includes each of on (mode 1) and on (mode 2). Since the information on the characteristics (features) in the state and the information on the power consumption are accumulated, if the identifying unit 27 can determine the state change of the electrical equipment, the consumption in such electrical equipment The amount of power can be determined.

  Further, the specifying unit 27 can also obtain the power consumption consumed by each specified electric device as follows. As described above, electricity (current / voltage) flowing through the power line 3 is sampled in order to extract features (features) unique to electrical equipment, and data such as current values, voltage values, and phase differences between them are acquired. Therefore, the specifying unit 27 can individually obtain the power consumption consumed by the specified electric device. In addition, when a plurality of electrical devices are connected to the outlets of the outlets 6 and 7, if the connection start time is different as described above, a change in current or voltage occurs at the connection start time. Based on this, it is possible to determine the amount of power consumed by each of the plurality of connected electrical devices.

As described above, the specifying unit 27 can specify the type of electrical device connected to each of the outlets of the outlets 6 and 7 based on the information (specific information) acquired by the sensor unit 23. it can.
Further, the specifying unit 27 generates specific information Z indicating the type of the specified electrical device and the power consumption consumed by each of the specified electrical devices. For the type of electrical equipment, the identifier of the electrical equipment set in the database is included in the specific information Z.
In addition, the processor 21 and the sensor unit 23 have a clock function, and the specific information Z includes information indicating the measurement time of the power consumption by the sensor unit 23 in addition to the identifier of the electrical device. Further, the specific information Z includes an on / off state change of the electric device and a time (state change time).

The sampling period Tb for measuring the amount of power by the sensor unit 23 can be 10 microseconds to 1 millisecond. Based on the information acquired at such a relatively fine sampling period Tb, the specifying unit 27 Identify the type of electrical equipment connected to the outlet.
Then, the communication unit 22 acquires the specific information Z and transmits the specific information to the management device 10.
The period Tc for generating the specific information Z may be sufficiently larger than the sampling period Tb by the sensor unit 23, and is, for example, 1 to several seconds (or 60 seconds). Further, the transmission cycle of the specific information Z to the management device 10 may be the same as or different from the cycle Tc for generating the specific information Z. When this transmission cycle is different from the sampling cycle Tc, it is preferable to set the transmission cycle to be larger than the sampling cycle Tc. In this case, the communication load is reduced by collecting and transmitting the specific information Z. It becomes possible.

[Management device 10]
FIG. 4 is a block diagram of the management apparatus 10. The management apparatus 10 includes a processor 11 having a CPU and the like, a communication unit 12, a monitor 13, and a memory 14. The processor 11 performs processing (calculation) for performing various functions in accordance with the computer program stored in the memory 14. As functions executed by the processor 11, the management device 10 can include a determination unit 17 and a control command unit 18 which will be described later.

The monitor 13 displays information (management information) on the result of processing by the processor 11 and notifies the power consumer of this information. FIG. 9 is an explanatory diagram of a display example of the monitor 13. On the monitor 13, information on the outlet (connection destination) of the outlet, the current state, and the usage duration is displayed as management information for each electric device (type). In addition to the name of the device, the attached information such as the manufacturer, model, model number, date of manufacture, and the like can be displayed together with the electrical device (type). This attached information is information stored in the database in association with the identifier.
The information shown in FIG. 9 is displayed on the monitor 13, so that the electric power consumer who sees the information uses what electric equipment is connected to where and consumes electric power. Can be grasped, and energy saving awareness can be promoted.

In FIG. 4, the communication unit 12 includes an interface that performs information communication between the measurement unit 20 and the outlet devices 30 and 40. The communication unit 12 can receive the individual information X transmitted from the outlet device 30 (40), can receive the specific information Z transmitted from the measurement unit 20, and serves as an acquisition unit that acquires various types of information. It has the function of
Note that the individual information X is information in which the outlet ID and the outlet ID are associated with the measured values of the individual power consumptions of the electrical devices connected to the outlets of the outlet as described above. When the communication unit 12 acquires the individual information X, the communication unit 12 identifies information indicating the individual power consumption consumed by the electrical equipment connected to each of the plurality of outlets 6 and 7 for each outlet and each outlet. Can be acquired.
Further, the specific information Z is information indicating the type of the electric device specified by the specifying unit 27 and the power consumption consumed by each of the specified electric devices, and the communication unit 12 stores the specific information Z. Can be acquired.

  Then, the determination unit 17 by the processor 11 has a function of determining the outlet of the outlet that is the connection destination of the electrical device whose type is specified by the specification unit 27 based on the specific information Z and the individual information X. ing. The determination process by the determination unit 17 will be described with a specific example later.

In addition, when the determination unit 17 determines the outlet of the outlet to which the electrical device is connected and generates management information based on the determination result, the control command unit 18 by the processor 11 determines the management information based on the management information. Can function.
For example, from the state where the management information shown in FIG. 9 is generated, for example, a plug is connected to the outlet 6a of the outlet 6 with the outlet ID “001” and the outlet 6a with the outlet ID “00A”. It is assumed that the electrical equipment management system 1 detects that an overcurrent is about to flow through the electrical equipment. In this case, the control command unit 18 quickly generates a command signal E indicating that the supply of power is forcibly cut off to the insertion port 6a, and the command signal E is transmitted from the communication unit 12 to the outlet device. It transmits to 30 communication parts 34.

The relay control unit 33 of the outlet device 30 that has received this command signal E cuts off the power supply to the insertion port 6a based on the command signal E. Thereby, the electric device in which the plug is connected to the insertion opening 6a can be automatically turned off. The relay control unit 33 can also automatically switch from the off state to the on state.
Since such automatic turn-off control can be performed, for example, before the main circuit breaker 5a of the distribution board 5 (see FIG. 1) functions due to an overcurrent and stops power supply to the outlets 6 and 7, for example. Thus, it is possible to stop power supply only to a part of the insertion opening 6a, and to prevent all electric devices from being turned off.

  Hereinafter, a specific example of the electrical device management method performed by the electrical device management system 1 configured as described above will be described.

[About electrical equipment management method (specific example 1)]
In FIG. 1, one electrical device (identifier “α”) is connected to the outlet 6a of the outlet 6 whose outlet ID is “001” (this inlet ID is “00A”), and the outlet ID is A case where no electrical device is connected to the outlet 7 which is “002” will be described. FIG. 10 is a flowchart for explaining the electrical device management method.

  When the power consumption consumed by the electrical device connected to the insertion port 6a is measured by the sensor unit 32 (see FIG. 2) of the outlet device 30 (step S1 in FIG. 10), the processor 31 Individual information X including the measurement value and the measurement time is generated (step S2). The sensor unit 32 also measures the other insertion openings 6b and 6c, and the measured value and the measurement time are included in the individual information X. In addition, although no electrical device is connected to the outlet 7, the sensor unit 42 measures the power consumption of the outlets 7a, 7b, and 7c of the outlet 7, and the processor 41 determines the measured value (zero). Individual information X including the measurement time is generated.

  FIG. 5 is an explanatory diagram of information included in the individual information X. The individual information X includes measurement values for each outlet ID and each insertion port ID for each measurement time. That is, according to the individual information X shown in FIG. 5A, the time “101” is set to the start time of the outlet with the outlet ID “001” and the outlet ID “00A”. It is shown that 100 watts of power is consumed, and 100 watts of power is continuously consumed at time “102” after this time “101”. Note that the individual information X shown in FIG. 5A is information generated by the processor 31 of the outlet device 30.

  Further, according to the individual information X shown in FIG. 5B, between the times “100” to “102”, the outlet ID is “002”, and the outlet ID is “00D” to “00F”. There is no power consumption at the slot. The individual information X shown in FIG. 5B is information generated by the processor 41 of the outlet device 40.

The individual information X generated in this way is transmitted from the communication units 34 and 44 of the outlet devices 30 and 40 to the communication unit 12 of the management device 10 (step S2).
As a result, the individual information X transmitted from the outlet devices 30 and 40 and indicating the individual power consumption consumed by the electrical devices connected to the outlets of the outlets 6 and 7 is transmitted to the outlet by the management device 10. Each is identified and acquired (step S20 in FIG. 10).

In addition to the processing in the outlet devices 30 and 40, the following processing is also executed in the measurement unit 20 (see FIG. 3).
When the sensor unit 23 measures the amount of electricity, voltage, current, and phase of electricity flowing through the power line 3 (step S11 in FIG. 10), the processor 21 uses the measurement value and the measurement time for specifying. Information is generated (step S12). In addition, since the electric energy etc. which the sensor part 23 measures are the electric energy etc. of the electricity which flows through the power line 3 (refer FIG. 1), the measured value is all connected to the outlet of the outlets 6 and 7. The total amount of power consumed by the electrical equipment. As described above, the measurement unit 20 has the grid power grid side as a measurement target from the distribution board 5 and is consumed by all the electric devices connected to the outlets of the outlets 6 and 7 that are divided from the distribution board 5. The information on the power to be used (information for identification) can be acquired (step S12).

And the specific | specification part 27 specifies the kind of electric equipment connected to the insertion port of the outlet sockets 6 and 7 based on this information for specification (step S13). Note that the specifying unit 27 cannot specify which outlet of each outlet is connected to which electrical device is connected.
Further, the specifying unit 27 generates specific information Z indicating the type of the specified electrical device and the power consumption consumed by each of the specified electrical devices (step S14). This power consumption is associated with the time measured by the sensor unit 23. The electrical device identification processing and the processing for obtaining the power consumption consumed by each of the identified electrical devices are as described above, and the description thereof is omitted here.

FIG. 6 is an explanatory diagram of information included in the specific information Z. The specific information Z includes the type (identifier) of the specified electrical device, the on / off state change, and the power consumption for each measurement time.
In the present embodiment, as described above, one electrical device is connected to the outlet 6a of the outlet 6 whose outlet ID is “001” (this outlet ID is “00A”). As shown in the figure, as the specific information Z, at time “101”, information indicating that the state of the electric device having the identifier “α” changes from “off to on” and the power consumption is “100 W”. Is generated by the specifying unit 27.

In this way, the measurement unit 20 identifies the type of the electrical device connected to the outlets of the outlets 6 and 7 based on the identification information, and identifies the identified type of the electrical device and the specified type. Specific information Z indicating the amount of power consumed by each electrical device is acquired.
The specific information Z is transmitted to the communication unit 12 of the management device 10 (step S14), and the specific information Z is acquired by the management device 10 (step S20).

Based on the individual information X (FIGS. 5A and 5B) transmitted from the outlet devices 30 and 40 and the specific information Z transmitted from the measurement unit 20 (FIG. 6), the type is specified by the specifying unit 27. The outlet of the outlet that is the connection destination of the electrical device having the identified identifier “α” is determined (step S21).
That is, the determination unit 17 of the management device 10 collates the individual information X shown in FIG. 5 with the specific information Z shown in FIG. 6 (matching process). In the case of the present embodiment, the same time “101” is included in both the individual information X and the specific information Z as the time when the state of power consumption has changed from “0 W” to “100 W”. Thus, it can be determined that the connection destination of the electrical device with the identifier “α” is “the outlet with the outlet ID“ 001 ”and the outlet with the outlet ID“ 00A ””.

As described above, the determination unit 17 collates the time “101” when the power consumption amount indicated by the individual information X is changed with the time “101” when the power consumption amount indicated by the specific information Z is changed. The outlet of the outlet that is the connection destination of the electric device whose type is specified by 27 is determined. In other words, the time when the power consumption amount indicated by the individual information X changes and the time when the power consumption amount indicated by the specific information Z coincides with each other, so that the specified electrical device can be inserted into which outlet. It is possible to grasp the usage status as to whether it is connected.
When such determination processing is performed by the determination unit 17, the processor 11 can display the result on the monitor 13 of the management apparatus 10 (step S22 in FIG. 10).

[About electrical equipment management method (specific example 2)]
In FIG. 1, one electrical device (identifier “α”) is connected to the outlet 6a of the outlet 6 whose outlet ID is “001” (this inlet ID is “00A”), and the outlet ID is A case will be described in which one electrical device (identifier “β”) is connected to the insertion port 7a of the outlet 7 that is “002” (this insertion port ID is “00D”).

When the power consumption consumed by the electrical device connected to the insertion port 6a is measured by the sensor unit 32 (see FIG. 2) of the outlet device 30 (step S1 in FIG. 10), the processor 31 Individual information X including the measurement value and the measurement time is generated (step S2). The sensor unit 32 also measures the other insertion openings 6b and 6c, and the measured value and the measurement time are included in the individual information X.
Further, when the power consumption consumed by the electrical device connected to the insertion port 7a is measured by the sensor unit 42 of the outlet device 40 (step S1 in FIG. 10), the processor 41 determines the measured value and Individual information X including the measurement time is generated (step S2). In addition, the sensor part 42 also measures about the other insertion ports 7b and 7c, and the measured value and measurement time are included in the said individual information X.

  FIG. 7 is an explanatory diagram of information included in the individual information X. The individual information X includes measurement values for each outlet ID and each insertion port ID for each measurement time. That is, according to the individual information X shown in FIG. 7A, the time “101” is set to the start time of the outlet with the outlet ID “001” and the outlet ID “00A”. It is shown that 100 watts of power is consumed, and 100 watts of power is continuously consumed at time “102” after this time “101”. Note that the individual information X shown in FIG. 7A is information generated by the processor 31 of the outlet device 30.

  Further, according to the individual information X shown in FIG. 7B, the time “101” is set as the start time for the outlet with the outlet ID “002” and the outlet ID “00D”. It is shown that 200 watts of power is consumed, and 200 watts of power is continuously consumed at time “102” after this time “101”. Note that the individual information X shown in FIG. 7B is information generated by the processor 41 of the outlet device 40.

The individual information X generated in this way is transmitted from the communication units 34 and 44 of the outlet devices 30 and 40 to the communication unit 12 of the management device 10 (step S2).
Thus, the individual information X transmitted from the outlet devices 30 and 40 and indicating the individual power consumption consumed by the electrical devices connected to the outlets of the outlets 6 and 7 is inserted by the management device 10. Each mouth is identified and acquired (step S20 in FIG. 10).

In addition to the processing in the outlet devices 30 and 40, the following processing is also executed in the measurement unit 20 (see FIG. 3).
When the sensor unit 23 measures the amount of electricity, voltage, current, and phase of electricity flowing through the power line 3 (step S11 in FIG. 10), the processor 21 uses a specific value including the measurement value and the measurement time. Information is generated (step S12). In addition, since the electric energy etc. which the sensor part 23 measures are the electric energy etc. of the electricity which flows through the power line 3 (refer FIG. 1), the measured value is all connected to the outlet of the outlets 6 and 7. The total amount of power consumed by the electrical equipment. Thus, the measurement unit 20 makes all the electric equipment connected to the outlets of the outlets 6 and 7 divided from the distribution board 5 by measuring the grid power network side from the distribution board 5. Thus, information on the power consumed (information for identification) can be acquired (step S12).

And the specific | specification part 27 specifies the kind of electric equipment connected to the insertion port of the outlet sockets 6 and 7 based on this information for specification (step S13). Note that the specifying unit 27 cannot specify which outlet of each outlet is connected to which electrical device is connected.
Further, the specifying unit 27 generates specific information Z indicating the type of the specified electrical device and the power consumption consumed by each of the specified electrical devices (step S14). This power consumption is associated with the time measured by the sensor unit 23. The electrical device specifying process is as described above, and the description thereof is omitted here.

FIG. 8 is an explanatory diagram of information included in the specific information. The specific information Z includes the type (identifier) of the specified electrical device, the on / off state change, and the power consumption for each measurement time.
In the present embodiment, as described above, one electrical device is connected to the outlet 6a of the outlet 6 whose outlet ID is “001” (this outlet ID is “00A”). As shown in the figure, as the specific information Z, at time “101”, information indicating that the state of the electric device having the identifier “α” changes from “off to on” and the power consumption is “100 W”. Is generated by the specifying unit 27.
Further, in the present embodiment, since one electrical device is connected to the outlet 7a of the outlet 7 whose outlet ID is “002” (this outlet ID is “00D”), it is shown in FIG. As described above, as the specific information Z, information indicating that the electrical device having the identifier “β” changes its state from “off to on” at time “101” and its power consumption is “200 W”. It is generated by the specifying unit 27.

In this way, the measurement unit 20 identifies the type of the electrical device connected to the outlets of the outlets 6 and 7 based on the identification information, and identifies the identified type of the electrical device and the specified type. Specific information Z indicating the amount of power consumed by each electrical device is acquired.
The specific information Z is transmitted to the communication unit 12 of the management device 10 (step S14), and the specific information Z is acquired by the management device 10 (step S20).

Based on the individual information X (FIGS. 7A and 7B) transmitted from the outlet devices 30 and 40 and the specific information Z transmitted from the measurement unit 20 (FIG. 8), the type is specified by the specifying unit 27. And the outlet of the outlet that is the connection destination of the electrical device with the identifier “α” and the electrical device with the identifier “β” identified (step S21).
That is, the determination unit 17 of the management device 10 collates the individual information X shown in FIG. 7 with the specific information Z shown in FIG. 8 (matching process). In the case of this embodiment, the same time “101” is included in both the individual information X and the specific information Z as the time when the state of power consumption changes from “0 W” to “100 W”. Since both the individual information X and the specific information Z include the same power consumption “100 W” at the same time “101”, the connection destination of the electrical device with the identifier “α” is “outlet ID. It is possible to determine that the outlet is “001” and the insertion port ID is “00A”.
Furthermore, the same time “101” is included in both the individual information X and the specific information Z as the time when the state of the power consumption has changed from “0 W” to “200 W”. And the specific information Z include the same power consumption “200 W” at the same time “101”, the connection destination of the electrical device with the identifier “β” is “Outlet ID is“ 002 ”. It is possible to determine that the outlet is an outlet having an insertion slot ID “00D”.

In this manner, the determination unit 17 collates the time “101” when the power consumption amount indicated by the individual information X has changed with the time “101” when the power consumption amount indicated by the specific information Z has changed, and the individual information X Is compared with the magnitude of the power consumption amount indicated by the specific information Z, and the outlet of the outlet that is the connection destination of the electrical device whose type is specified by the specifying unit 27 is determined. That is, since the information indicated by the individual information X and the information indicated by the specific information Z coincide with each other, it is possible to determine the usage status as to which outlet of the specified electrical device is connected. It becomes possible to grasp.
When such determination processing is performed by the determination unit 17, the processor 11 can display the result on the monitor 13 of the management apparatus 10 (step S22 in FIG. 10).

[Electrical equipment management system 1 and management method]
According to the electrical device management system 1 according to the above embodiment, the identifying unit 27 of the measurement unit 20 identifies the type of electrical device connected to the outlets of the outlets 6 and 7, and generates the measurement unit 20. The specified information Z includes the type of the specified electrical device and the power consumption consumed by each specified electrical device. Further, in the individual information X generated by the outlet devices 30 and 40, information indicating individual power consumption consumed by the electrical equipment connected to the outlets of the outlets 6 and 7 is identified for each outlet. Has been included.
Therefore, the determination unit 17 of the management apparatus 10 can determine the outlet of the outlet that is the connection destination of the electrical device whose type is specified by the specification unit 27 based on the specific information Z and the individual information X. As a result, it becomes possible for the management apparatus 10 to grasp the usage status of what type of electrical equipment is connected to which outlet of the outlet and power is consumed.

  Therefore, for example, as the automatic off control performed by the electrical device management system 1 using the relay control unit (33, 43) of the outlet device (30, 40), the electrical device currently used is used. Of these, if it is necessary to cut off the power supply from the lowest priority, it is necessary to know what electrical device is connected to which outlet of which outlet. According to the electrical device management system 1, since this can be grasped, it is possible to cut off the power supply in order from the electrical device with the lowest priority. In addition, as an electrical apparatus with high priority, there exists a refrigerator, for example, and there exists an air-conditioning installation (air conditioner) as an electrical apparatus with low priority.

Further, in the electrical equipment management system 1 according to the present embodiment, information used by the identifying unit 27 to identify the type of electrical equipment connected to the electrical outlets of the outlets 6 and 7 is acquired for each electrical outlet. Instead, it is obtained by measuring the power line 3 on the grid power network side from the distribution board 5. For this reason, even if the number of outlets (plugs) increases, a highly functional device that performs processing at a fine sampling cycle to specify the type of electrical equipment is provided for each plug of outlets 6 and 7. There is no need to provide one, and it is only necessary to provide one on the distribution board 5 or the power line 3 on the grid power network side of the distribution board 5. That is, it is only necessary that the single measuring unit 20 has such a high-functional device.
For this reason, even if the number of outlets increases, it is not necessary to provide a high-functional device or the like for each outlet of the outlet, so that it is possible to prevent the entire electric device management system 1 from increasing in cost.

  Further, the sampling period Ta for measuring the power consumption of each electrical device by the sensor unit 32 (42) of the outlet device 30 (40), and the sampling period for measuring the current / voltage flowing through the power line 3 by the sensor unit 23 of the measurement unit 20 Tb and the period Tc in which the specifying unit 27 of the measurement unit 20 generates the specific information Z will be described.

In the measurement unit 20, the electricity (current and / or voltage) flowing through the power line 3 is measured by the sensor unit 23 (measurement unit) with a fine first sampling period Tb. The sampling period Tb is 10 microseconds or more and 1 millisecond or less, but preferably 10 microseconds or more and 100 microseconds or less. However, the identification unit 27 may generate the identification information Z by performing the identification process at the third sampling period Tc (1 to several seconds) sufficiently larger than the sampling period Tb, and the same period. The specific information Z may be transmitted to the management apparatus 10 at Tc (Tb << Tc).
In the outlet device 30 (40), the sampling period Ta for measuring the individual power consumption of the electrical equipment is 1 second or more and 60 seconds or less, preferably 1 second or more and 10 seconds or less. is there. Further, the generation cycle of the individual information X based on the measurement result and the transmission cycle of the individual information X may be the same as or different from the sampling cycle Ta.
As a result, in the management device 10, if the communication unit 12 acquires the individual information X and the specific information Z at the second sampling period Ta (1 to 60 seconds) sufficiently larger than the fine first sampling period Tb. Good (Tb << Ta). In the present embodiment, the sampling period Tc and the sampling period Ta are the same (Tc = Ta).

That is, the sensor unit 23 of the measurement unit 20 is a highly functional device that performs processing at a fine sampling period Tb (10 microseconds to 1 millisecond).
On the other hand, the communication part 12 of the management apparatus 10 should just acquire the individual information X (and specific information Z) with a sampling period (1 to several seconds) larger than this sampling period Tb. Therefore, it is only necessary to measure and transmit the individual power consumption at a large sampling period (1 to several seconds) on the side of the outlet devices 30 and 40 that are the generation sources of the individual information X. It is not necessary to provide a high-functional device or the like that performs processing in seconds to 1 millisecond) for each outlet device 30, 40. Therefore, even if there are a plurality of outlet devices 30 and 40, it is possible to prevent the entire electrical equipment management system 1 from becoming costly.

In addition, embodiment disclosed this time is an illustration and restrictive at no points. The scope of rights of the present invention is not limited to the above-described embodiments, but includes all modifications within the scope equivalent to the configurations described in the claims.
For example, in the embodiment (FIG. 1), the number of outlets is “2”, but other numbers may be used, and the number of sub-breakers may be changed according to the number of outlets. Also, the number of outlets of each outlet can be changed.

The measurement unit 20 may be installed outside the distribution board 5 instead of inside the distribution board 5, and the wiring (power line 3) from the distribution board 5 on the grid power network side, that is, the current / voltage flowing through the main trunk. Just measure. For example, the measurement unit 20 may be installed in the power meter 4.
Transmission / reception of information between the management device 10, the measurement unit 20, and the outlet devices 30 and 40 may be wireless, but may also be power line carrier communication (PLC).
The management apparatus 10 may be connected to a communication network such as the Internet through a communication line.
