本発明の一実施形態による無線通信装置を備えた無線通信システムについて図面を参照して説明する。図１は無線通信システムの構成を示す。図１（図３も同様）において、破線は無線による接続を示す。無線通信システム１００は、宅内各所に電力を分配供給する分電盤１と、通信機能を有するスマートメータ（電力メータ）２と、エアコン、冷蔵庫、洗濯機等の各種の家電機器３等によって構成される。分電盤１には、家電機器３の他、太陽光発電機４、燃料電池５、蓄電池６、電気自動車７及び情報処理端末８等が必要に応じて接続される。家電機器３、電気自動車７及び情報処理端末８の動作に必要な電力は、分電盤１及び蓄電池６から供給される。蓄電池６には、太陽光発電機４、燃料電池５によって得た電荷が貯えられる。太陽光発電機４、燃料電池５及び蓄電池６は、停電時の自家発電にも利用できる。   A wireless communication system including a wireless communication apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a wireless communication system. In FIG. 1 (also in FIG. 3), a broken line indicates a wireless connection. The wireless communication system 100 includes a distribution board 1 that distributes and distributes power to various places in a home, a smart meter (power meter) 2 having a communication function, various home appliances 3 such as an air conditioner, a refrigerator, and a washing machine. The In addition to the home appliance 3, a solar power generator 4, a fuel cell 5, a storage battery 6, an electric vehicle 7, an information processing terminal 8, and the like are connected to the distribution board 1 as necessary. Electric power necessary for the operation of the home appliance 3, the electric vehicle 7 and the information processing terminal 8 is supplied from the distribution board 1 and the storage battery 6. In the storage battery 6, electric charges obtained by the solar power generator 4 and the fuel cell 5 are stored. The solar power generator 4, the fuel cell 5, and the storage battery 6 can also be used for in-house power generation during a power failure.

分電盤１と、家電機器３、太陽光発電機４、燃料電池５、蓄電池６、電気自動車７及び情報処理端末８等とは、相互に通信可能でありＨＥＭＳネットワークを構成する。分電盤１に接続されるこれらの機器は、その全てが通信機能を有している必要はなく、その一部が通信機能を有していればよい。家電機器３の移動や増設時等の施工の容易さを考慮すると、ＨＥＭＳネットワーク内の通信には、無線を用いるのが望ましいが、頻繁に移動させない機器同士では、有線を用いて通信してもよい。   Distribution board 1, home appliance 3, solar power generator 4, fuel cell 5, storage battery 6, electric vehicle 7, information processing terminal 8, and the like can communicate with each other and constitute a HEMS network. All of these devices connected to the distribution board 1 do not need to have a communication function, and some of them need only have a communication function. Considering the ease of construction when the home appliances 3 are moved or added, it is desirable to use wireless for communication within the HEMS network, but devices that do not move frequently may communicate with each other using wired communication. Good.

分電盤１には、ＨＥＭＳ管理装置１０が設けられ、ＨＥＭＳ管理装置１０は、太陽光発電機４及び燃料電池５による発電、蓄電池６の充電、家電機器３等による電力消費等を管理する。太陽光発電機４及び燃料電池５による発電状況、蓄電池６の充電状況、家電機器３等による電力消費状況は、情報処理端末８によって表示することができる。情報処理端末８に表示された情報を確認しながら、必要に応じて情報処理端末８を操作等することにより、各機器の動作を設定し電力の流れを最適化することができる。情報処理端末８は、分電盤１の近傍の壁面等に設置された専用のモニタ装置であってもよいし、スマートフォン等の携帯型情報処理端末であってもよい。   The distribution board 1 is provided with a HEMS management device 10 that manages power generation by the solar power generator 4 and the fuel cell 5, charging of the storage battery 6, power consumption by the home appliance 3 and the like. The power generation status by the solar power generator 4 and the fuel cell 5, the charging status of the storage battery 6, and the power consumption status by the home appliance 3 can be displayed by the information processing terminal 8. By checking the information displayed on the information processing terminal 8 and operating the information processing terminal 8 as necessary, the operation of each device can be set and the power flow can be optimized. The information processing terminal 8 may be a dedicated monitor device installed on a wall surface in the vicinity of the distribution board 1, or may be a portable information processing terminal such as a smartphone.

スマートメータ２は、分電盤１に有線にて接続されており、送電線から電力の供給を受けて分電盤１に供給すると共に、宅内において累積して消費された電力を表示する。上述の通りスマートメータ２は、通信機能を有し、他宅に設置されているスマートメータ２等を介して電力会社のサーバ５０に接続され、スマートメータネットワークが構成される。複数のスマートメータ２間の通信及びスマートメータ２とサーバ５０との通信は、有線又は無線を介してなされる。   The smart meter 2 is connected to the distribution board 1 by wire, receives power from the power transmission line, supplies the distribution to the distribution board 1, and displays the electric power accumulated and consumed in the house.

For example, it is possible to construct and operate a more advanced HEMS by receiving hourly charge information and power provision information transmitted from an electric power company and reflecting them in the power consumption in the house. More specifically, when the electricity rate is different for each time zone, the HEMS management device 10 controls the home appliance 3 so that the home appliance 3 is operated preferentially at a time when the rate is low, so that the monthly The electricity bill to pay can be reduced.

The PLC modem 16 is directly connected to the trunk line 13, superimposes a high-frequency information signal on the alternating current flowing through the trunk line 13, and performs bidirectional communication with the smart meter 2 by wire. In addition, a second communication unit 15B that performs wireless two-way communication with the home appliance 3 in the HEMS network is configured by the control unit 17, the transmission unit 18, the reception unit 19, and the antenna 20 or the like. .

制御部１７は、無線通信装置１５の各部の制御を司る。例えば、制御部１７は、受信部１９を介して得たＨＥＭＳネットワーク内の家電機器３等の情報を、ＰＬＣモデム１６を介してスマートメータ２に伝達したり、送信部１８を介して情報処理端末８に送信したりする。また、電力会社から送信されスマートメータ２及びＰＬＣモデム１６を介して得た情報を、送信部１８を介して情報処理端末８に送信したり、同情報に基づいて、ＨＥＭＳネットワーク内の家電機器３等を制御する信号を送信部１８に送信させたりする。このとき、ＰＬＣモデム１６とスマートメータ２間においてなされる有線通信のプロトコルと、ＨＥＭＳネットワーク内でなされる無線通信のプロトコルとは異なっているので、制御部１７は、プロトコル変換部（通信データ変換部）として機能する。制御部１７は、この機能により、通信データのプロトコルを相互に変換し、それにより、通信データを相互に通信可能に変換する。すなわち、制御部１７は、ＰＬＣモデム１６を含む第１通信部１５Ａで送受信されるＰＬＣのプロトコルと、送信部１８及び受信部１９を含む第２通信部１５Ｂで送受信されるＨＥＭＳネットワークのプロトコルを相互に変換するゲートウェイ機能を有する。   The control unit 17 controls each unit of the wireless communication device 15. For example, the control unit 17 transmits information on the home appliances 3 and the like in the HEMS network obtained via the reception unit 19 to the smart meter 2 via the PLC modem 16 or information processing terminal via the transmission unit 18. Or send to 8. Information transmitted from the electric power company and obtained via the smart meter 2 and the PLC modem 16 is transmitted to the information processing terminal 8 via the transmission unit 18, or the home appliance 3 in the HEMS network based on the information. For example, the transmission unit 18 is caused to transmit a signal for controlling and the like. At this time, since the protocol of wired communication performed between the PLC modem 16 and the smart meter 2 is different from the protocol of wireless communication performed in the HEMS network, the control unit 17 is configured to transmit the protocol conversion unit (communication data conversion unit). ). With this function, the control unit 17 converts the communication data protocol to each other, and thereby converts the communication data so that they can communicate with each other. That is, the control unit 17 exchanges the protocol of the PLC transmitted / received by the first communication unit 15A including the PLC modem 16 and the protocol of the HEMS network transmitted / received by the second communication unit 15B including the transmission unit 18 and the reception unit 19. It has a gateway function to convert to

図３は、参考例として従来の分電盤２０１に特許文献１に記載された技術を適用した無線通信システム２００を示す。この無線通信システム２００においては、本実施形態のＨＥＭＳ管理装置１０の替わりに、特許文献１に記載された無線通信装置を有し、ＨＥＭＳネットワーク内で通信を司るＨＥＭＳコントローラ２１０が適用される。ＨＥＭＳコントローラ２１０は、ＨＥＭＳネットワークを介した家電機器３等の制御機能を有する。   FIG. 3 shows a wireless communication system 200 in which the technology described in Patent Document 1 is applied to a conventional distribution board 201 as a reference example. In this wireless communication system 200, instead of the HEMS management apparatus 10 of the present embodiment, a HEMS controller 210 that includes the wireless communication apparatus described in Patent Document 1 and manages communication within the HEMS network is applied. The HEMS controller 210 has a control function of the home appliance 3 and the like via the HEMS network.

ＨＥＭＳコントローラ２１０のＡＣアダプタ（図示せず）は、分電盤２０１から分岐された壁コンセントに接続され、ＨＥＭＳコントローラ２１０に電力を供給する。このＨＥＭＳコントローラ２１０には、電力計測部１４が存在しないので、電力を計測する機能と無線通信機能を有する電力計測ユニット２１４がＨＥＭＳネットワーク内に別途設けられる。なお、電力計測ユニット２１４は、電力計測部１４と同様に、分電盤２０１内の幹線１３に接続される。   An AC adapter (not shown) of the HEMS controller 210 is connected to a wall outlet branched from the distribution board 201 and supplies power to the HEMS controller 210. Since the HEMS controller 210 does not include the power measurement unit 14, a power measurement unit 214 having a function of measuring power and a wireless communication function is separately provided in the HEMS network. The power measurement unit 214 is connected to the main line 13 in the distribution board 201 in the same manner as the power measurement unit 14.

また、屋外に設置されたスマートメータ２と屋内に設置されたＨＥＭＳコントローラ２１０との間で、建物の壁越しに無線通信が行われるので、建物の構造（鉄筋などの配置、壁の材質、厚み）等によっては電波の減衰が生じて、通信品質が低下する虞がある。また、ＨＥＭＳコントローラ２１０のＡＣアダプタが接続されたプラグに隣接するプラグに家電機器３が接続された場合、家電機器３が発生するノイズが壁コンセントやＡＣアダプタを介してＨＥＭＳコントローラ２１０に混入することがある。その場合、ノイズがＨＥＭＳコントローラ２１０の通信品質に悪影響を及ぼす虞がある。   In addition, since wireless communication is performed through the wall of the building between the smart meter 2 installed outdoors and the HEMS controller 210 installed indoors, the structure of the building (arrangement of reinforcing bars, wall material, thickness, etc.) ) Or the like, radio wave attenuation may occur and communication quality may be degraded. In addition, when the home appliance 3 is connected to a plug adjacent to the plug to which the AC adapter of the HEMS controller 210 is connected, noise generated by the home appliance 3 is mixed into the HEMS controller 210 via a wall outlet or an AC adapter. There is. In that case, noise may adversely affect the communication quality of the HEMS controller 210.

これに対して、図１に示した本実施形態の無線通信システム１００においては、上述したＡＣアダプタに相当する構成が不要となる。従って、無線通信システム１００の構成が簡素化され、コストダウンを図ることができる。また、電力計測ユニット２１４に相当する構成は、分電盤１の内部のＨＥＭＳ管理装置１０に実装されているので、同構成を別途設置する手間を省くことができる。   On the other hand, in the wireless communication system 100 of the present embodiment shown in FIG. 1, a configuration corresponding to the above-described AC adapter is not necessary. Therefore, the configuration of the wireless communication system 100 is simplified, and the cost can be reduced. In addition, since the configuration corresponding to the power measurement unit 214 is mounted on the HEMS management apparatus 10 inside the distribution board 1, it is possible to save the trouble of separately installing the configuration.

また、屋外のスマートメータ２と屋内のＨＥＭＳ管理装置１０との間では、有線にて通信がなされるので、建物の構造の影響を受けることなく、良好な通信品質を安定して確保でき通信の信頼性を高めることができる。なお、スマートメータ２とＨＥＭＳ管理装置１０との通信は、既存の電力線すなわち系統電源線を用いた電力線通信である。従って、別途通信線を施工する必要がないので、無線通信システム１００の導入に要するコストと手間を削減できる。特に、マンションなどの集合住宅においては、スマートメータネットワーク内の通信方式に電力線通信を採用することが多く、その場合、スマートメータ２に搭載する通信方式を電力線通信に統一することができる。これにより、スマートメータ２の構成がより一層簡素化され、無線通信システム１００のさらなるコストダウンを図ることができる。   In addition, since communication is performed by wire between the outdoor smart meter 2 and the indoor HEMS management apparatus 10, it is possible to stably secure good communication quality without being affected by the structure of the building. Reliability can be increased. Communication between the smart meter 2 and the HEMS management apparatus 10 is power line communication using an existing power line, that is, a system power supply line. Therefore, since it is not necessary to construct a separate communication line, the cost and labor required for introducing the wireless communication system 100 can be reduced. In particular, in a housing complex such as a condominium, power line communication is often adopted as a communication method in the smart meter network. In this case, the communication method mounted on the smart meter 2 can be unified with power line communication. Thereby, the configuration of the smart meter 2 is further simplified, and the cost of the wireless communication system 100 can be further reduced.

また、本実施形態のＨＥＭＳ管理装置１０は、分電盤１の内部に設けられていることから、家電機器３からは比較的離れた場所に位置される。（分電盤１の近傍には、家電機器３が設置されることが少ない、のが通常である。）従って、家電機器３が発生するノイズは、ＨＥＭＳ管理装置１０に到達するまでに減衰し、家電機器３が発生するノイズによって無線通信装置１５の通信品質が悪化する虞を抑制できる。   Moreover, since the HEMS management apparatus 10 of this embodiment is provided in the inside of the distribution board 1, it is located in the place comparatively distant from the household appliances 3. FIG. (It is normal that home appliances 3 are rarely installed in the vicinity of the distribution board 1.) Therefore, noise generated by the home appliances 3 attenuates before reaching the HEMS management device 10. The possibility that the communication quality of the wireless communication device 15 deteriorates due to noise generated by the home appliance 3 can be suppressed.

図４は、本発明による無線通信システムの変形例の構成を示す。また、図５は、同変形例に適用される無線通信装置及びその周辺の構成を示す。無線通信システム３００は、分電盤１の替わりに電力計測通信装置３１４を有する分電盤３０１を備え、ＨＥＭＳコントローラ２１０と同等のＨＥＭＳコントローラ３１０をさらに備える点で、無線通信システム１００とは相違する。電力計測通信装置３１４は、宅内で消費される電力の計測機能と、スマートメータ２との通信機能等を備える。ＨＥＭＳネットワークを介した家電機器３等との通信及び家電機器３等の制御は、ＨＥＭＳコントローラ３１０が司る。   FIG. 4 shows a configuration of a modification of the wireless communication system according to the present invention. FIG. 5 shows a configuration of a wireless communication apparatus and its surroundings applied to the modified example. The wireless communication system 300 is different from the wireless communication system 100 in that it includes a distribution board 301 having a power measurement communication device 314 instead of the distribution board 1 and further includes a HEMS controller 310 equivalent to the HEMS controller 210. . The power measurement communication device 314 has a function of measuring power consumed in the home, a function of communicating with the smart meter 2, and the like. The HEMS controller 310 governs communication with the home appliance 3 and the like through the HEMS network and control of the home appliance 3 and the like.

すなわち、分電盤３０１には、電力計測通信装置３１４が設けられ、電力計測通信装置３１４は、宅内で消費される電力を計測し、ＨＥＭＳコントローラ３１０に計測した電力量の通知などの通信を行う。ＨＥＭＳコントローラ３１０は、太陽光発電機４及び燃料電池５による発電、蓄電池６の充電、家電機器３等による電力消費等を制御する。太陽光発電機４及び燃料電池５による発電状況、蓄電池６の充電状況、家電機器３等による電力消費状況は、情報処理端末８によって表示することができる。情報処理端末８の機能等については、上記と同様である。   That is, the distribution board 301 is provided with a power measurement communication device 314. The power measurement communication device 314 measures power consumed in the home and performs communication such as notification of the measured power amount to the HEMS controller 310. . The HEMS controller 310 controls power generation by the solar power generator 4 and the fuel cell 5, charging of the storage battery 6, power consumption by the home appliance 3 and the like. The power generation status by the solar power generator 4 and the fuel cell 5, the charging status of the storage battery 6, and the power consumption status by the home appliance 3 can be displayed by the information processing terminal 8. The functions of the information processing terminal 8 are the same as described above.

図５は、分電盤３０１の構成を示す。分電盤３０１は、分電盤１と同様に、電力計測通信装置３１４、主幹ブレーカ１１、複数の分岐ブレーカ１２を有する。主幹ブレーカ１１は、主幹ブレーカ１１から延出された系統電源線である幹線１３を介して分岐ブレーカ１２と接続されている。分岐ブレーカ１２は、幹線１３から分岐して、各系統の壁コンセントに電力を供給する。また、分岐ブレーカ１２は、各系統の壁コンセントを介して家電機器３等の負荷に過電流が流れたとき、その系統の回路を遮断する。各分岐ブレーカ１２の電流の総和が過大になったときには、主幹ブレーカ１１が作動して全ての系統の回路を遮断する。   FIG. 5 shows the configuration of the distribution board 301. Similar to the distribution board 1, the distribution board 301 includes a power measurement communication device 314, a main breaker 11, and a plurality of branch breakers 12. The main breaker 11 is connected to the branch breaker 12 via a main line 13 that is a system power line extending from the main breaker 11. The branch breaker 12 branches from the main line 13 and supplies power to the wall outlets of each system. Further, when an overcurrent flows to a load such as the home appliance 3 through the wall outlet of each system, the branch breaker 12 interrupts the circuit of that system. When the sum of the currents of the branch breakers 12 becomes excessive, the main breaker 11 is activated to shut off all the circuits of the system.

電力計測通信装置３１４は、主幹ブレーカ１１から延出された幹線１３に直接的に接続され、幹線１３から電力の供給を受けて動作する。また、電力計測ユニットは、幹線１３に接続されている複数の分岐ブレーカ１２のうち、ＨＥＭＳ管理装置１０に電力を供給するために設けられている専用の分岐ブレーカ１２に接続されていてもよい。いずれの場合にあっても、電力計測ユニットは、分電盤１の内部の系統電源線に直接的に有線で接続される。電力計測通信装置３１４は、電力計測部１４と、無線通信装置１５等を有する。電力計測部１４は、幹線１３に接続され、宅内で消費される電力を計測する。電力計測部１４によって計測された電力の情報は、ＰＬＣモデム１６を介してスマートメータ２に送信されたり、送信部１８を介してＨＥＭＳコントローラ３１０や情報処理端末８に送信されたりする。   The power measurement communication device 314 is directly connected to the main line 13 extended from the main breaker 11 and operates by receiving power supply from the main line 13. The power measurement unit may be connected to a dedicated branch breaker 12 provided to supply power to the HEMS management device 10 among the plurality of branch breakers 12 connected to the main line 13. In any case, the power measurement unit is directly connected to the system power supply line inside the distribution board 1 by wire. The power measurement communication device 314 includes a power measurement unit 14 and a wireless communication device 15. The power measurement unit 14 is connected to the trunk line 13 and measures the power consumed in the house. Information on the power measured by the power measurement unit 14 is transmitted to the smart meter 2 via the PLC modem 16 or transmitted to the HEMS controller 310 and the information processing terminal 8 via the transmission unit 18.

参考例として図３に示した無線通信システム２００においては、スマートメータネットワーク及びＨＥＭＳネットワークがそれぞれ独立して進化する過程で、互換性の問題が発生することがある。しかしながら、本発明による無線通信システムの変形例として図４，５に示した無線通信システム３００にあっては、以下の効果が生ずる。すなわち、両ネットワークの通信方式の差異を電力計測通信装置３１４によって吸収することにより、それぞれのネットワークの進化に自由度を持たせることができる。例えば、ＨＥＭＳネットワークの通信方式を変更する場合であっても、電力計測通信装置３１４によって適宜対応させることにより、スマートメータ２の仕様に影響を及ぼすことが少ないため、ＨＥＭＳネットワークの進化を妨げる虞が少ない。スマートメータネットワークの通信方式を変更する場合も同様である。   In the wireless communication system 200 shown in FIG. 3 as a reference example, a compatibility problem may occur in the process in which the smart meter network and the HEMS network evolve independently of each other. However, in the radio communication system 300 shown in FIGS. 4 and 5 as a modification of the radio communication system according to the present invention, the following effects are produced. In other words, the power measurement communication device 314 absorbs the difference between the communication methods of the two networks, so that the degree of freedom of the evolution of each network can be given. For example, even when the communication method of the HEMS network is changed, the power metering communication device 314 appropriately responds, so that the specification of the smart meter 2 is hardly affected, which may hinder the evolution of the HEMS network. Few. The same applies when the communication method of the smart meter network is changed.

以上のように、本実施形態の無線通信装置１によれば、分電盤１内の系統電源線である幹線１３に直接的に接続され、幹線１３から電力の供給を受けて動作するように構成されているので、停電時以外の平穏時において電源を喪失することがない。   As described above, according to the wireless communication device 1 of the present embodiment, it is directly connected to the main line 13 that is the system power supply line in the distribution board 1 and operates by receiving power supply from the main line 13. Because it is configured, the power supply is not lost in a peaceful time other than during a power failure.

また、ＰＬＣモデム１６、制御部１７、送信部１８及び受信部１９等によって構成される無線通信装置１５の本体部分が、分電盤１の筐体１Ａによって覆われて保護される構成を有している。従って、長年の使用においても粉塵等の侵入を防止することができ、結線部の漏電に伴う火災の発生を抑制することができる。   Further, the main body portion of the wireless communication device 15 configured by the PLC modem 16, the control unit 17, the transmission unit 18, the reception unit 19 and the like is covered and protected by the casing 1A of the distribution board 1. ing. Therefore, even when used for many years, intrusion of dust and the like can be prevented, and the occurrence of a fire due to leakage in the connection portion can be suppressed.

なお、本発明は上記実施形態の構成に限られることなく、少なくとも無線通信装置１が分電盤１内の系統電源線である幹線１３に直接的に接続され、幹線１３から電力の供給を受けて動作するように構成されていればよい。   The present invention is not limited to the configuration of the above embodiment, and at least the wireless communication device 1 is directly connected to the trunk line 13 which is a system power line in the distribution board 1 and receives power supply from the trunk line 13. As long as it is configured to operate.

また、本発明は種々の変形が可能である。例えば、ＰＬＣモデム１６、制御部１７、送信部１８及び受信部１９等によって構成される無線通信装置１５の本体部分が、分電盤１の筐体１Ａの内部に配設され、アンテナ２０は、分電盤１の筐体１Ａの外部に露出して配設される形態であってもよい。この形態においては、筐体１Ａの外部に配設されたアンテナ２０によってＨＥＭＳネットワーク内の各機器との無線通信性能を高めることができる。特に、筐体１Ａが金属材料で形成されている場合であっては、静電遮蔽による無線通信性能の低下を抑制できる。   The present invention can be variously modified. For example, the main body portion of the wireless communication device 15 configured by the PLC modem 16, the control unit 17, the transmission unit 18, the reception unit 19, and the like is disposed inside the housing 1A of the distribution board 1, and the antenna 20 The form arrange | positioned exposed to the exterior of the housing | casing 1A of the distribution board 1 may be sufficient. In this form, the wireless communication performance with each device in the HEMS network can be enhanced by the antenna 20 disposed outside the housing 1A. In particular, when the housing 1A is formed of a metal material, it is possible to suppress a decrease in wireless communication performance due to electrostatic shielding.

また、無線通信装置１５は、分電盤１の筐体１Ａの外部に配設されていてもよい。この場合、無線通信装置１５は、分電盤１の筐体１Ａに連接して配設されているのが好ましい。この場合においては、収容空間が狭い分電盤にも本発明を適用可能となる。また、専用の分電盤１を新設することなく、既存の分電盤２０１を用いて本発明の無線通信システム１００を構築することができる。また、筐体１Ａが金属材料で形成されている場合も、上記と同様である。   The wireless communication device 15 may be disposed outside the housing 1A of the distribution board 1. In this case, it is preferable that the wireless communication device 15 is arranged in a manner connected to the housing 1A of the distribution board 1. In this case, the present invention can be applied to a distribution board having a small accommodation space. Moreover, the radio | wireless communications system 100 of this invention can be constructed | assembled using the existing distribution board 201, without newly installing the exclusive distribution board 1. FIG. The same applies to the case where the housing 1A is formed of a metal material.

また、スマートメータ２と第１通信部１５Ａとの間の通信には、無線を用いるように構成されていてもよい。この場合にあっては、電力線通信のためのＰＬＣモデム１６が不要となり、スマートメータ２との間で無線通信を行うための送受信部がアンテナと共に設けられる。スマートメータネットワークの通信方式における物理層と、ＨＥＭＳネットワークの通信方式における物理層が同一である場合は、第２通信部１５Ｂの送信部１８、受信部１９及びアンテナ２０を第１通信部１５Ａと兼用するように構成されていてもよい。   The communication between the smart meter 2 and the first communication unit 15A may be configured to use radio. In this case, the PLC modem 16 for power line communication is unnecessary, and a transmission / reception unit for performing wireless communication with the smart meter 2 is provided together with an antenna. When the physical layer in the communication system of the smart meter network is the same as the physical layer in the communication system of the HEMS network, the transmission unit 18, the reception unit 19 and the antenna 20 of the second communication unit 15B are also used as the first communication unit 15A. It may be configured to.

また、無線通信装置１５及び無線通信システム１００は、ＨＥＭＳネットワーク以外の種々の無線通信ネットワークに広く適用可能である。これに伴い、電力計測部１４が計測する電力は、宅内に限られず、所定の閉じた領域内で消費される電力であってもよい。   Further, the wireless communication device 15 and the wireless communication system 100 can be widely applied to various wireless communication networks other than the HEMS network. Accordingly, the power measured by the power measuring unit 14 is not limited to the home, but may be power consumed in a predetermined closed area.
