Description

  The present invention relates to a plug receptacle and a power strip provided with a tag reader that reads identification information added to an IC (integrated circuit) tag of an insertion plug, and in particular, a home energy management system (home energy management system) that uses the plug receptacle as an embedded outlet. energy management system: hereinafter referred to as HEMS).

  In conventional home automation (especially HEMS), information technology (Information Technology: IT) is used to connect each electrical device such as an air conditioner in a house, energy consuming devices such as hot water supply devices, and a central controller via a network. Thus, the energy consumption and / or security management and comfort in the house are provided, such as monitoring and automatically controlling the energy consumption such as the power consumption and the operation state in the energy consuming equipment such as each electric equipment. The monitor installed in the central control unit of the HEMS digitizes the power consumption and the operating status of each electrical device, compares it with past data, and provides energy-saving advice and visualization of CO2 reduction amount. Expectation is expected as a countermeasure technology to the problem of composting. In addition, the smart grid concept integrates the power supply and demand situation in a large-scale power system and the amount of electricity consumed in each house, as well as the photovoltaic power generators, fuel cells or wind power generators installed individually in each house. In order to grasp the power consumption of each house, the installation of watt-hour meters with communication functions is being promoted by the efforts of each power company. However, there is a limit to the acquisition of individual information in each house, and there are limits to the difficulty. In order to realize efficient energy saving and countermeasure technology against global warming problems with these technologies, it is necessary to install “HEMS” in the house. It is expected that it will be indispensable to grasp the individual electricity consumption and operation status of the installed electrical equipment and the like and to control the individual operation.

In the home energy management system by “HEMS”, communication between the central controller and each electrical device is indispensable. However, as a communication method, (1) power line communication (X10, INSTEON, KNX, LONWORKS, etc.), (2) Those using another communication line (KNX, LONWORKS, etc.), and (3) Those using wireless communication (X10, INSTEON, KNX, etc.). In addition, as the operation control method of each electric device, the above-described communication method is used to directly control each electric device or the like, and each electric device connected to the outlet is provided with an ON-OFF function in the outlet. Indirect control by turning the outlet on and off.
For example, the following conventional techniques can be cited as communication methods and operation control methods for each of these electrical devices.

  A conventional web access mechanism incorporates a web access function in a device including a web server that provides device web pages. The device includes a built-in network interface that allows access to the device web page from a web browser. The user of the web browser accesses the user interface functions for the device through the device web page. It provides a user-friendly screen-based interface for various devices without the need to develop expensive hardware and software applications for each different device (see, for example, US Pat.

In addition, in conventional electronic devices, TVs, VTRs, and PCs are connected via a network such as a LAN. Further, this network is connected to a public line via a gateway unit in order to exchange information with the outside. ing. A private address among IP addresses used in the Internet is assigned to each electronic device and gateway unit in the home. Each electronic device has a built-in WWW server having a function of sending data written in HTML by HTTP, and each electronic device has a WWW browser having a function of displaying HTML data received by HTTP on the screen. Built-in (see, for example, Patent Document 2).

  In addition, the conventional timer outlet has a time measuring unit, and when it coincides with the time set by the remote control transmitter via the signal receiving unit of the remote control, the control signal for controlling the specified outlet with the same time from the control unit to the specified operation. Then, the supplied commercial power supply is supplied to an output outlet through a switch circuit that performs ON-OFF control. Also, the timer outlet is provided with a remote control signal transmission unit, and the setting data stored in the timer outlet memory is converted into a remote control signal according to the designation from the remote control transmitter, and displayed on the display unit of the remote control transmitter (for example, (See Patent Document 3).

  Furthermore, the conventional power management system is composed of a table tap having a plurality of outlets, and a home server that controls the outlets and can communicate with the push type telephone via the network, and transmits from the push type telephone to the home server. It is possible to check the power supply state for the electrical equipment connected to a plurality of outlets provided at the table tap at home, or switch the power supply state if necessary by the control signal thus generated (for example, patents) Reference 4).

  In addition, the conventional remote control method for electrical equipment is such that electrical equipment used in homes and the like is connected to a power source via a control connector, and the characteristic current waveform of the electrical equipment is stored in a server database in advance. The electric device is identified from the current waveform currently transmitted from the electric device by accessing a mobile phone, etc., the state of the electric device is detected, and a measure corresponding to this is taken based on this detection (For example, see Patent Document 5).

  In addition, the conventional electrical product management system has a control function in which a general line connected to the Internet network and a home distribution line connected to the power line of the power company are drawn into the home component, and signals are superimposed. Power is supplied to the fourth electrical product corresponding to the attached power strip and the communication network. In the first to third electrical products, the current status of the electrical product and the power on / off control are performed by the power tap with a control function. The instruction is given by the portable terminal of the outside component unit. In the case of the fourth electric product, not only power on / off but also remote control of various functions is possible. Since the power line is used, the configuration and control are simplified (for example, see Patent Document 6).

  However, the above-described techniques (Patent Document 1 to Patent Document 6) can be used for the purpose of controlling the communication and operation of each electric device (turning on / off the power supply). In order to control each electric device or the like, there is a problem that a subsystem for communication and control is required on the electric device side. In other words, incorporating this subsystem into electrical equipment not only leads to an increase in manufacturing costs, but also cannot be applied to general electrical equipment that is currently in widespread use, so these methods have become widespread in all electrical equipment. Without it, it cannot be realized.

  Further, among the communication methods (1) to (3) described above, it is considered that the method (2) can realize the communication / control subsystem at the lowest cost. However, in this method (2), there is a problem that the user is always forced to connect both the power cable and the communication cable to the electric device, which is not realistic.

Speaking of a method in which each electrical device is controlled indirectly by ON / OFF of the outlet, in particular, the conventional timer outlet described in Patent Document 3 and the conventional power management system described in Patent Document 4 are targeted for the control unit. The outlet number (ID number) of the outlet (timer outlet) is recognized, but since the control unit does not have a means for recognizing information on the electrical equipment connected to the target outlet, Accordingly, there is a problem that it is not possible to turn on / off the power supply of the outlet.

  In addition, the conventional remote control method for electrical devices described in Patent Document 5 identifies each electrical device and various types of electrical devices for electrical devices connected to different outlets in the same outlet. There is a problem that is difficult.

  In addition, according to the conventional electrical product management system described in Patent Document 6, an electrical product operator initially registers electrical products (except electrical products compatible with a power supply network) that use a power strip with a control function. Thereafter, there is a problem that it is necessary to make an input request every time a change occurs and to update the memory with the change contents.

  As described above, Patent Documents 1 to 6 first describe that, in the case of controlling by directly communicating with an electric device, the electric device requires a communication function, and the general electric device currently in widespread use. And secondly, it is necessary to register the electrical equipment information when connecting to an outlet that controls the outlet by communicating with the outlet, and when replacing, it is necessary to register again. It is difficult to reliably identify the electrical equipment connected to the outlet, etc. ”, and it can be broadly classified and has problems that are difficult to realize. The current situation is not reached.

  As means for solving these problems at the same time, a conventional power strip has a power plug at one end and a plurality of outlets at the other end. An RFID tag is attached or embedded in the power plug. A power line communication (PLC) modem is connected to the power line between the power plug and the outlet. The RFID tag reader reads identification information of an RFID tag attached to a power plug connected to an outlet. For the control circuit, a technique has been proposed in which the identification information read by the RFID tag reader is notified to the management server by the PLC modem together with the identification information of the power strip (for example, see Patent Document 7).

JP 10-149270 A JP 10-191463 A JP-A-4-372894 JP 2002-44882 A JP 2003-2559569 A JP 2002-305845 A JP 2007-88957 A

However, the conventional power tap described in Patent Document 7 has a power plug of an electronic device that is received by the blade holder in order to efficiently generate electromagnetic induction between the antenna coil of the RFID tag reader and the antenna coil of the RFID tag. It is considered that the direction of the strong magnetic field generated concentrically based on the current flowing through the blade is parallel to the winding direction of the antenna coil of the RFID tag. For this reason, in the conventional power strip, the CPU (central processing unit) of the RFID tag is activated by electromagnetic induction with a strong magnetic field generated concentrically, and the identification information stored in the RFID tag in the power plug of the electronic device Is overwritten or initialized and erased, and it is difficult to continuously manage RFID tags, and re-registration is indispensable every time a power plug is replaced with an outlet. .

  Further, since the conventional power strip described in Patent Document 7 has a built-in transformer in the PLC modem, it leads to an increase in the manufacturing cost of the power strip, and it is not assumed that the power line passes an electric signal having a high frequency. However, there is a problem that a leaked radio wave due to power line communication may affect wireless communication using a short wave band and medical equipment.

  In addition, the conventional power tap described in Patent Document 7 communicates with the PLC modem of the management server via the power line by the PLC modem provided. However, in order to use the power line as a communication path, the connected information device There is a possibility that information leaks from the high-frequency information signal from the house to the outside, and there is a problem in terms of security that communication contents in the house are not leaked to the outside.

  The present invention has been made to solve the above-described problems, and the identification information stored in the RFID tag (IC tag) in the power plug (plug-in plug) of the electronic device (electric device) is electronic. It provides a plug holder that is not erased by overwriting or initialization by electromagnetic induction with a strong magnetic field generated from the blade of the power plug (plug-in plug) when the device (electric device) is energized. is there.

  The present invention also provides a home energy management system that does not require a built-in PLC modem in the embedded outlet and can reduce the manufacturing cost of the embedded outlet. In addition, the present invention can eliminate the possibility that leakage radio waves due to power line communication affect wireless communication using a short wave band and medical equipment, and information signals due to power line communication flow out from the house to the outdoors. It provides a home energy management system that prevents information leakage and strengthens security.

  The tag reader 2 is branched and connected to an electric wire connecting the residential distribution board 30 and the insertion slot 1 and reads the identification information added to the IC tag 411 of the electric device 400, as shown in FIG. As shown, an antenna coil 2a, a power supply circuit 2b, a CPU 2c, a radio frequency circuit 2d, a modulation circuit 2e, and a demodulation circuit 2f are provided.

The antenna coil 2a is configured such that the center axis O2 of the antenna coil 2a of the tag reader ₂ and the IC tag 411 are obtained in order to obtain a radio wave intensity necessary for transmission / reception of radio waves with the antenna coil 411a in the IC tag 411 of the electric device 400. was coincident with the center axis O ₁ of the antenna coil 411a, it is disposed at positions the antenna coil 411a and the counter of the IC tag 411.

  The power supply circuit 2b rectifies the alternating current supplied from the commercial power supply 20 via the residential distribution board 30 and supplies it to the CPU 2c.

  When transmitting a signal radio wave of a specific frequency from the antenna coil 2a, the CPU 2c outputs a signal to the modulation circuit 2e, the modulation circuit 2e modulates the signal, and outputs the signal to the radio frequency circuit 2d. 2d is converted into an electric signal that becomes a radio wave of a specific frequency and is output to the antenna coil 2a.

  On the other hand, when the antenna coil 2a receives a signal radio wave of a specific frequency, the radio frequency circuit 2d converts the signal radio wave of the specific frequency received into an electrical signal and outputs it to the demodulation circuit 2f. It demodulates to the command signal which CPU2c can recognize, and outputs it to CPU2c.

However, having a central axis O ₃ substantially parallel to the center axis O ₂ of the antenna coil 2a in the tag reader 2, as long as being disposed near the antenna coil 2a, is not limited to this configuration. For example, as shown in FIG. 5, the protective coil 3a is composed of a single protective coil 3a, and the central axis O ₃ of the protective coil 3a is aligned with the central axis O ₂ of the antenna coil 2a so that the antenna coil 2a is included. It may be configured to.

  Further, as shown in FIG. 6 (a), the protection coil 3a generates a magnetic field H1 that penetrates the coil (protection coil 3a) in accordance with an alternating current from the commercial power source 20, thereby showing the protection coil 3a in FIG. 6 (b). As shown in FIG. 6C, the antenna coil in the IC tag 411 of the electric device 400 generates a magnetic field H2 generated concentrically based on the current flowing in the blade 412 of the insertion plug 410 received by the blade receiver 12. Tilt to the surface S including 411a.

  That is, the protective coil 3a tilts the magnetic field H2 with respect to the surface S including the antenna coil 411a, so that the identification information added to the IC tag 411 in the plug 410 of the electric device 400 is overwritten or initialized. It can be prevented from being erased.

  Note that the inclination of the magnetic field H2 with respect to the plane S including the antenna coil 411a is ideally 90 degrees, but in reality, it is a combined vector of 90 degrees of the magnetic field H1 and the magnetic field H2, and therefore 45 degrees. Is the maximum tilt angle.

  The high-frequency conversion unit 3b is branched and connected to an electric wire connecting the residential distribution board 30 and the insertion port unit 1, and converted into a rectifier 3c that converts an alternating current of the commercial power supply frequency from the commercial power supply 20 into a direct current.

For example, the home server 40 (HEMS central control device 50) is connected via the home LAN such as a LAN cable or a router / hub. )It is connected to the. The IP network connection unit 7 does not need to be directly connected to the home server 40 (HEMS central control device 50) via a home LAN, and uses power line communication (hereinafter referred to as PLC). Using an existing PLC product, a slave device of the PLC product is connected to the IP network connection unit 7 via a LAN cable, and the master device of the PLC product is connected to the home server 40 (central control of the HEMS via a LAN cable or a router / hub). It is good also as a structure connected to the apparatus 50). As described above, the use of the PLC product is a case where a normal outlet in which a LAN cable passes through a wall or under the floor of a house or the like and is not laid in advance to the insertion port is replaced with the power management outlet 10 according to the present embodiment. It is effective for. However, using a PLC product may cause information leakage in which a high-frequency information signal from the electric device 400 (information device) connected to the power management outlet 10 flows out of the house 100 to the outside. Is preferably used.

As a premise, the electric power from the commercial power source 20 is supplied to the high frequency conversion unit 3b via the residential distribution board 30, and the alternating current of the commercial power source frequency is converted into a direct current by the rectifier 3c of the high frequency conversion unit 3b. The converted direct current is converted into a high-frequency alternating current by the inverter 3d of the high-frequency converter 3b, and is supplied to the protective coil 3a. That is, the protective coil 3 a generates a magnetic field H <b> 1 that penetrates the coil according to the alternating current from the commercial power supply 20.

  First, the user of the power management outlet 10 inserts the blade 412 of the insertion plug 410 of the electric device 400 into the blade receiving hole 11 of the insertion section 1 of the power management outlet 10, and The blade receiver 12 is caused to receive the blade 412 of the insertion plug 410.

  The electric device 400 is based on the current flowing through the blade 412 of the insertion plug 410 received by the blade receiver 12 when power from the commercial power supply 20 is supplied via the residential distribution board 30 and the insertion port 1. Thus, the magnetic field H2 is generated concentrically.

  In this case, the magnetic field H1 generated based on the current flowing through the protective coil 3a tilts the magnetic field H2 generated based on the current flowing through the blade 412 of the insertion plug 410, and the IC tag in the insertion plug 410 of the electric device 400 The identification information added to 411 is prevented from being overwritten or initialized.

  In addition, the tag reader 2 is supplied with power from the commercial power supply 20 via the residential distribution board 30, and the CPU 2c generates a command signal for reading the identification information from the IC tag 411, and the modulation circuit 2e and Radio waves are transmitted from the antenna coil 2a to the antenna coil 411a of the IC tag 411 via the radio frequency circuit 2d.

  In the IC tag 411, the CPU 411c reads the identification information stored in the memory 411g via the radio frequency circuit 411d and the demodulation circuit 411e based on the radio wave received by the antenna coil 411a.

  The IC tag 411 transmits radio waves from the antenna coil 411a to the antenna coil 2a of the tag reader 2 through the modulation circuit 411f and the radio frequency circuit 411d, with the identification information read from the memory 411g by the CPU 411c.

  Based on the radio wave received by the antenna coil 2a, the tag reader 2 acquires the identification information added to the IC tag 411 via the radio frequency circuit 2d and the demodulation circuit 2f, and outputs it to the control unit 6.

  The control unit 6 is connected to the home LAN via the IP network connection unit 7 by using the IP address stored in the IP address storage unit 8 by the communication circuit 6b, and the acquired identification information is centrally controlled by the HEMS. To device 50. Moreover, the control part 6 calculates the information which shows the electricity supply state to the electric equipment 400 connected to the insertion port part 1 with the drive measurement circuit 6a based on the value measured by the measurement part 9, as needed, The state of the electrical device 400 is detected from the change in the energized state, the power consumption of the electrical device 400 is integrated from the information indicating the energized state, and these calculation results are transmitted to the central control device 50 of the HEMS. .

  The central control apparatus 50 of HEMS acquires the identification information of the electric equipment 400 connected to the insertion port 1. Moreover, the central control apparatus 50 of HEMS acquires the calculation result by the drive measurement circuit 6a as needed.

  Then, the central control device 50 of the HEMS determines whether it is necessary to supply power to the electrical device 400 based on the obtained identification information of the electrical device 400 and / or the calculation result by the drive measurement circuit 6a. When it is determined that it is necessary to supply power, control information is transmitted to the control unit 6 of the power management outlet 10 to which the electric device 400 is connected.

  Then, the control unit 6 to which the control information is transmitted supplies power to the electric device 400 by releasing and releasing the excitation of the switch unit 4 connected to the insertion port 1 to which the corresponding electric device 400 is connected. To stop.

  In this case, the power management outlet 10 includes a transmission unit (not shown) that transmits an operation signal (for example, a radio signal such as infrared rays or radio waves) for remotely operating the target electric device 400.

  In addition, the HEMS designates a custom code for distinguishing the electric device 400 and each operation (for example, if the electric device 400 is a “television receiver”, “power ON / OFF”, “channel switching”, etc.). A database (not shown) is stored which stores a series of codes composed of combinations with data codes (in this case, “power ON” data codes).

  With these configurations, the central control device 50 of the HEMS acquires identification information of the electrical device 400 connected to the insertion port 1 when the insertion plug 410 of the electrical device 400 is inserted into the insertion port 1. .

  Then, the central control device 50 of the HEMS generates a series of codes composed of a combination of the custom code and the data code (“power ON”) of the electric device 400 based on the acquired identification information of the electric device 400, and the HEMS database. Read from.

  Then, the central control device 50 of the HEMS transmits a series of codes read from the HEMS database to the control unit 6 of the power management outlet 10 to which the target electric device 400 is connected.

  When receiving a series of codes, the control unit 6 of the power management outlet 10 controls a transmission unit (not shown) and transmits the series of codes to the outside of the power management outlet 10 as an operation signal. Upon receiving the operation signal, the target electric device 400 turns on the power based on the data code (“power ON”).

(Other embodiments of the present invention)
The HEMS (power management outlet 10, power strip 500) according to the first embodiment, the second embodiment, and the third embodiment described above realizes, for example, the following six functions depending on the usage of the user. can do.

The functions that can be realized are not only for energy saving but also for the purpose of ensuring the safety and security of electricity use.
1. Peak cutting of load due to smart grid / HEMS support The central control device 50 of the HEMS according to the present embodiment determines which of the outlets 1 of each power management outlet 10 and each outlet 501 of each power tap 500 Whether such an electric device 400 is connected can always be grasped.

  The central control device 50 of the HEMS stores the identification information of the electric device 400 recorded in the IC tag 411 of the electric device 400 and a database (information on the function and power consumption of each electric device 400) installed on the Internet 300. DB) and the function and power consumption of each electric device 400 can be recognized.

  Thereby, the central control device 50 of HEMS judges whether it is the electric equipment 400 which requires constant operation, such as PC, or the electric equipment 400 which does not require constant operation, such as an electric stove, and always operates. It is possible to turn off only the electric device 400 that is not required, or to turn off the power according to the priority of the electric device 400.

  In particular, each insertion port 1 of each power management outlet 10 in the building, each insertion port 501 of each power tap 500, and the electric devices 400 connected thereto can function as the end of the smart grid. It is possible to connect the electrical device 400 to the electrical device 400 that can be turned off at the time of peak power demand.

The power supply can be turned off in units of 1 (insertion port portion 501).

2. Wiring guide that can easily cope with peak cut of load To enhance the effect of peak cut as described above, combination of electrical equipment with high priority and electrical equipment with low priority, or electrical equipment that requires constant operation It must be avoided that a combination with an electrical device that does not require constant operation is connected to one outlet of an embedded outlet by a multi-tap. This is because, for example, a high-priority electrical device and a low-priority electrical device are connected to each multi-tap outlet, and the multi-tap plug is connected to one of the embedded outlets. This is to avoid a situation in which the power of a low-priority electrical device cannot be turned off in order to prevent the power of a high-priority electrical device from being turned off in a situation where it is connected to one outlet. .

  As described above, the HEMS (power management outlet 10, power strip 500) according to the present embodiment detects wiring based on a combination of electrical devices 400 having different priorities or a combination of electrical devices 400 having different necessity for continuous operation. It is possible to prompt the user to change the wiring to the optimum combination.

3. Potential danger prevention by octopus foot wiring In the field, power consumption exceeding the rated current may be concentrated at one outlet of the embedded outlet due to so-called octopus foot wiring.

  On the other hand, since the HEMS according to the present embodiment can identify the electrical device 400 connected to each insertion port 1 of each power management outlet 10 and each insertion port 501 of each power tap 500, the power supply It is possible to predict the total power consumption when all of the power sources of the plurality of electrical devices 400 connected to the single outlet portion 1 of the management outlet 10 via the power tap 500 are turned on.

  For this reason, the HEMS (power management outlet 10, power strip 500) according to the present embodiment turns on the power of each electrical device 400 when there is a risk of exceeding the maximum power of the outlet of the embedded outlet or the multi-tap. The user can be alerted to detect the danger in advance before turning it on, and to stop the octopus foot wiring that causes accidents such as electric leakage and fire.

4). Facilitating the recall of electrical equipment (electric products) In recent years, the recall of electrical equipment (electric products) such as petroleum fan heaters and refrigerators has continued. In response to such a recall related to human life, a manufacturer company must spend a huge amount of money and continue to search for electrical devices (electric products) to be recalled.

  On the other hand, in the electrical device 400 having the plug 410 corresponding to the HEMS according to the present embodiment, the plug 410 is inserted into the outlet portion 1 or the power strip of the power management outlet 10 when it is to be recalled. By being connected to the 500 insertion ports 501, it is detected as a recall target by the HEMS according to the present embodiment. In particular, in the case of a serious recall, it is possible to automatically turn off the power supply of the electrical device 400 to be recalled and forcibly prohibit the use of the electrical device 400 to be recalled.

5. Cooperation with Indoor Camera The HEMS (power management outlet 10, power tap 500) according to the present embodiment is in the vicinity of a person in the house 100 by cooperating with a person in the house 100 and an indoor camera that recognizes the electric device 400. It is possible to realize a function of turning on or off the power source of only the electric device 400 located in the position.

6). Application to Home Security (especially Safety Confirmation System) As described above, the HEMS according to the present embodiment is connected to the outlet 1 (the outlet 501) of the power management outlet 10 (the power tap 500). The device 400 and the power consumption of the electric device 400 can be grasped in real time. The identification of electrical devices that consume power and the monitoring of the power consumption are important elements as safety information for elderly people (especially living alone). For this reason, the HEMS according to the present embodiment is applied to an existing technology (safety confirmation system) for notifying a user's mobile phone of the safety of an elderly person or the like by monitoring the trend of power consumption of an electric device. The safety of the elderly person or the like can be provided to the user of the safety confirmation system in more detail (along with information on the usage state (start, continuation, end) of the electric device 400 by the elderly person or the like).

The business prospects and advantages of the HEMS (power management outlet 10, power strip 500) according to the first, second, and third embodiments described above will be described below.
Conventionally, the reason why the proposal like the HEMS according to the present embodiment has not been made is that the wiring system is standardized and fixed, so that it is interpreted that there is no room for change in the wiring system. It is done. On the other hand, electric power companies are one of the few organizations that are in a position to ask the world for such proposals and promote standardization.

  Under such circumstances, the HEMS (power management outlet 10, power strip 500) according to the present embodiment is an effective method for incorporating the home electric device 400 into the peak cut of the load. If spread, the predicted value of the peak of power demand can be lowered, and the capital investment of power generation, transformation and transmission facilities can be suppressed.

  Here, a case where the HEMS (power management outlet 10, power strip 500) according to the present embodiment is not used, for example, a case where a communication and control subsystem is incorporated in an electrical device (electric product) will be considered.

  In this case, if a subsystem is to be incorporated in all electrical equipment (electric products), consumers who do not currently need communication and control functions in the electrical equipment (electric products) are also required to incorporate the subsystem. By purchasing an electrical device (electrical product) that adds an additional cost to the price, the additional cost is borne.

  This is for a small number of users who need communication and control functions for electrical equipment (electrical products), and for the majority of consumers who do not currently need communication and control functions for electrical equipment (electrical products). It will bear the cost, and contrary to the principle of beneficiary payment, it is difficult to think that it will be realized.

  For this reason, at present, it is considered that the subsystem is incorporated in only a small part of the electrical equipment (electrical products) having many varieties.

  However, in this case, when trying to use the communication and control functions of the electric device (electric product), there are few electric devices (electric products) incorporating the subsystem, and the degree of freedom to select the electric device (electric product) is significantly lost. In the end, the communication and control functions of electrical equipment (electric products) end without spreading.

On the other hand, in the HEMS (power management outlet 10, power strip 500) according to the present embodiment, the IC tag 411 is pasted on the plug plug 410 without modifying a general electric device that is currently popular. It can be used as it is. As will be described later, as long as the home-side system is constructed, the additional cost required for the electric device 400 is only the IC tag 411 of the plug plug 410, so that the additional cost by the IC tag 411 is negligible. . In addition, if a function for registering information in the IC tag 411 is provided in the central control device 50 of the HEMS, a user of the HEMS purchases a dedicated (rewritable) IC tag 411 and installs the IC in the plug plug 410 himself. Because the central controller 50 automatically registers information in the IC tag 411 simply by pasting the tag 411, a general household user who does not have specialized knowledge and skills constructs the system himself, It is possible to respond freely to system expansion.

  Note that the majority of the additional costs required for the HEMS (power management outlet 10, power strip 500) according to the present embodiment is that the power management outlet 10 (the terminal of HEMS and Cost for the power strip 500, including installation work), and the principle of beneficiary burden is maintained. That is, the HEMS (power management outlet 10, power strip 500) according to the present embodiment is introduced by the user into the house 100 as necessary, and can be gradually spread.

  In addition, when the HEMS (power management outlet 10, power strip 500) according to the present embodiment becomes widespread, home appliance manufacturers incorporate new functions (communication and control) by incorporating the IC tag 411 into the plugs 410 of each electrical device 400. It can be differentiated from products that do not support new functions (communication and control functions).

  In addition, it is considered to be welcomed by home appliance manufacturers that the foundation of the home appliance network by the HEMS according to the present embodiment is prepared together with the sales of the power management outlet 10 and the power strip 500.

  Further, considering the function capable of dealing with the recall described above, refusing to deal with the HEMS (power management outlet 10, power strip 500) according to the present embodiment may cause a situation where corporate social responsibility is accused. Since it may invite, the home appliance maker thinks that it does not oppose the proposal like HEMS concerning this embodiment.

  Also, in recent years, organizations that have spread the platform as a foundation, rather than just individual technologies, tend to take the lead in all industrial fields.

  In other words, with proposals such as HEMS according to the present embodiment, the power company including the applicant of the present application becomes a platform for home appliance networks such as HEMS, and it is possible to create a composition that leads hardware manufacturers such as the home appliance industry. It is considered to be.
