In the combined use of the conventional automatic energy meter reading system and the Internet system for each household of the apartment house, as shown in FIG. 4, the automatic energy meter reading system and the Internet system are installed independently. The distribution board room 1 is in the apartment house, and the meter storage box 2 is outside the indoor partition wall 3W of each home 3.

電力量自動検針システムは、電力会社の営業所等と接続される集合住宅外部の自動検針回線（ネットワーク）４と、集合住宅分電盤室に設置される外部自動検針回線４の終端装置である伝送装置５と、集合住宅分電盤室１と各家庭をＰＬＣで接続する場合に必要となる電気信号を電力線に重畳するためのＰＬＣ親機６と、ＰＬＣを使用する場合の集合住宅分電盤室１から各家庭３にAC100Vを供給するための配電線７と、各家庭のメータ収納箱２に設置されるＰＬＣ子機８と、電力使用量を計量するために各家庭に設置されている通信機能付電力量計９と、通信機能付電力量計９とＰＬＣ子機８とを接続するためのインタフェース装置１０とで構成されている。９通信機能付電力量計の通信は一般的にカレントループ方式が用いられており、ＰＬＣ子機８の持つインタフェースは一般的にイーサネット（登録商標）（登録商標）を使用しているため両者を接続するためにはインタフェース装置１０が必要となる。 The electric energy automatic meter reading system is a terminating device for an automatic meter reading line (network) 4 outside the apartment house connected to a power company sales office and the like, and an external automatic meter reading line 4 installed in the apartment house distribution board room. Transmission unit 5, PLC housing unit 1 and PLC master unit 6 for superimposing electric signals necessary for connecting each household with a PLC on the power line, and apartment housing distribution when using PLC A distribution line 7 for supplying AC100V from the panel room 1 to each home 3, a PLC slave unit 8 installed in the meter storage box 2 of each home, and installed in each home to measure the amount of power used The communication function-equipped watt-hour meter 9 and the interface function 10 for connecting the communication function-equipped watt-hour meter 9 and the PLC slave unit 8 are configured. 9 The communication loop of the watt-hour meter with a communication function generally uses the current loop method, and the interface of the PLC slave unit 8 generally uses Ethernet (registered trademark). In order to connect, the interface apparatus 10 is required.

インタネットシステムは、集合住宅に接続するための光ファイバ等の高速インタネット回線１１と、集合住宅分電盤室に設置され高速インタネット回線１１と接続された伝送装置１２と、分電盤室に設置され伝送装置１２と接続されたxDSL用親機１３と、分電盤室１と各家庭３とを接続している通信線１４と、各家庭に設置されxDSL用親機１３と通信線１４を介して接続されたxDSL子機１５と、xDSL子機１５と接続され各家庭で使用されるパーソナルコンピュータ（以下「以下パソコン」と略記する）１６とで構成されている。 The Internet system is installed in a distribution board room, a high-speed Internet line 11 such as an optical fiber for connecting to a housing complex, a transmission device 12 installed in the housing distribution board room and connected to the high-speed Internet line 11. An xDSL master unit 13 connected to the transmission device 12, a communication line 14 connecting the distribution board room 1 and each home 3, and an xDSL base unit 13 and communication line 14 installed in each home. Are connected to each other, and a personal computer (hereinafter abbreviated as “PC”) 16 connected to the xDSL slave 15 and used in each home.

以下に従来技術例１の動作について説明を行う。 The operation of the prior art example 1 will be described below.

これまでは、ＰＬＣは認可されている使用周波数帯域（10〜450ｋHz）の関係で、低速
のＰＬＣが用いられている。電力会社が設置している低速ＰＬＣを使用した電力量検針システムは一般的に図４のような構成をしており、電力会社の営業所等から検針指令がでると、自動検針回線４、ＰＬＣ親機６、配電線７、ＰＬＣ子機８を経由して通信機能付電力量計９に指示が伝わり、その応答として電力量計９の計量値が前述の検針指令とは逆のルートで返送され、自動検針回線４を介して営業所等でデータの収集が可能となる。 Until now, low-speed PLCs have been used because of the use frequency band authorized (10 to 450 kHz). A power meter reading system using a low-speed PLC installed by an electric power company is generally configured as shown in FIG. 4. When a meter reading command is issued from a power company sales office or the like, an automatic meter reading line 4, PLC An instruction is transmitted to the watt-hour meter 9 with communication function via the master unit 6, the distribution line 7, and the PLC slave unit 8, and as a response, the measured value of the watt-hour meter 9 is returned by the route opposite to the above-described meter reading command. Then, data can be collected at a sales office or the like via the automatic meter reading line 4.

インタネット等の用途に用いられる集合住宅のxDSL回線は、一般的に図４に示すような構成であり、集合住宅外部のインタネット高速回線１１と各家庭３とがxDSL回線で接続され各家庭のパソコン１６でインタネットが楽しめる構成となっている。 The xDSL line of an apartment house used for applications such as the Internet is generally configured as shown in FIG. 4, and the Internet high-speed line 11 outside the apartment house and each home 3 are connected by an xDSL line, and the personal computer of each household 16 can enjoy the Internet.

従来技術１の構成では、検針業務とインタネット等通信業務の事業者が別であり、これらのシステムを構成する装置や機器の設置、工事の施行等すべて別々に行われている。すなわち集合住宅分電盤室から各戸入り口まで２系統の伝送路および通信デバイスが必要となり、システムコストが非常に高価になるという欠点があった。また、通信線を宅内に入れるために、壁に２系統の伝送路用の２つの穴ＰＴ１，ＰＴ２を開けたり、夫々の伝送路の引き込みの工事が必要になるなどそれなりの工事が必要になった。機器設置スペース、機器の設置、取り付け工事コスト等の増加もシステム導入に大きな影響を与えるなどの問題があった。 In the configuration of the prior art 1, the operator for the meter reading work and the communication work such as the Internet are separate, and the installation of the devices and devices constituting these systems and the execution of the construction are all performed separately. In other words, two transmission lines and communication devices are required from the housing distribution board room to the entrance of each door, and there is a drawback that the system cost becomes very expensive. In addition, in order to put a communication line into the house, it is necessary to perform some kind of work such as opening two holes PT1 and PT2 for two transmission lines in the wall, or drawing in each transmission line. It was. Increases in equipment installation space, equipment installation, installation work costs, etc. have also had a significant impact on system introduction.

特開２００６-２５３９７１号公報（図２及びその説明）Japanese Patent Laying-Open No. 2006-253971 (FIG. 2 and its description)

前述のように、従来技術１の電力量自動検針システム及びインタネット併用システムでは、集合住宅分電盤室から各戸入り口まで２系統の伝送路および通信デバイスが必要となり、また、伝送路を宅内に入れるために、壁に２つの穴を開けることや、夫々の伝送路の引き込みの工事が必要になるなどそれなりの工事が必要になり、機器設置スペース、機器の設置、取り付け工事コスト等の増加もシステム導入に大きな影響を与えるなどの問題があった。
従来技術２によれば、ユニット装置を集合住宅分電盤室に配置することにより、集合住宅分電盤室から各戸入り口まで１系統の伝送路および通信デバイスでよくなり、機器設置スペース、機器の設置、取り付け工事コスト等の増加を抑制できる。しかし、従来技術２では電力量のデータがインタネットを流れることにより、セキュリティ上で問題である。
また、前記低速ＰＬＣとは違って、高速ＰＬＣは特性上分電盤とか分岐回路があると信号の減衰が大きく、それに伴い伝送速度が大幅に落ちることが知られている。 As described above, the automatic power meter reading system and the Internet combined system of the prior art 1 require two transmission lines and communication devices from the apartment house distribution panel room to each door entrance, and the transmission lines are put in the house. Therefore, it is necessary to do two kinds of work such as making two holes in the wall and drawing in each transmission line, and the system installation space, equipment installation, and installation work costs are also increased. There were problems such as having a big impact on the introduction.

Increase in installation and installation work costs can be suppressed. However, in the prior art 2, there is a problem in terms of security because power amount data flows through the Internet.
Further, unlike the low-speed PLC, it is known that a high-speed PLC has a characteristic that if a distribution board or a branch circuit is present, the signal is greatly attenuated, and the transmission speed is greatly reduced accordingly.

この発明は前述のような課題を解決するためになされたものであり、集合住宅の各家庭での使用電力量の自動検針と、各家庭での電力量とは異なる他の情報の通信とを、搬送波の周波数がＭＨｚ帯の高速ＰＬＣで共用する情報通信機能付電力量自動検針システムとした場合、セキュリティを確保し、高速ＰＬＣでの信号の減衰を低減して、集合住宅への情報通信機能付電力量自動検針システムの導入をし易くすることを目的とするものである。 The present invention has been made to solve the above-described problems, and performs automatic metering of the amount of electric power used in each household of an apartment house and communication of other information different from the amount of electric power in each household. , when the frequency of the carrier wave is a high-speed PLC information communication function with electric energy automatic meter reading systems sharing in the MHz band, to ensure security, to reduce the attenuation of the signal at high speed PLC, the information communication function to the apartment The purpose is to facilitate the introduction of an automatic power meter reading system.

高速ＰＬＣは特性上分電盤とか分岐回路があると信号の減衰が大きく、それに伴い伝送速度が大幅に落ちることが知られている。宅内用高速ＰＬＣ親機２５２は家庭内の分電盤より負荷側に設置される案もあるが、この場合にはアクセス系高速ＰＬＣの通信路に電力量計２６、家庭内分電盤２７等が入るため減衰が大きくなり通信速度が遅くなり家庭内でインタネット通信が困難になる可能性が高い。そこで、本実施の形態１では、宅内系高速ＰＬＣの親局２５２を、電力量計２６の近傍に、電力量計２６を経由しないように信号結合器２５２１を電力量計２６の負荷側電力量計端子台２６Ｔ２に接続して設置し、電力量計２６における信号レベルの減衰を回避し、分電盤２７での減衰に対しては宅内用高速ＰＬＣ親機（図示ＨＡ親機）の増幅機能で信号強化し、アクセス系高速ＰＬＣと宅内系高速ＰＬＣ間で高い信号レベルでの通信を行うことを可能にしてある。 It is known that a high-speed PLC has a characteristic that if a distribution board or a branch circuit is present, the signal is greatly attenuated, and the transmission speed is greatly reduced accordingly. There is a plan that the home high-speed PLC master unit 252 is installed on the load side from the distribution board in the home. In this case, the watt hour meter 26, the home distribution board 27, etc. are provided in the communication path of the access high - speed PLC. Therefore, there is a high possibility that the attenuation will increase and the communication speed will slow down, making Internet communication difficult in the home. Therefore, in the first embodiment, the signal combiner 2521 is connected to the load-side electric energy of the watt hour meter 26 so that the master station 252 of the home high - speed PLC is not passed through the watt hour meter 26 in the vicinity of the watt hour meter 26. Installed in connection with meter terminal block 26T2, avoids signal level attenuation in watt-hour meter 26, and amplifies function of high-speed PLC master unit for home ( HA master unit in the figure ) for attenuation at distribution board 27 The signal is strengthened by this to enable communication at a high signal level between the access high - speed PLC and the home high - speed PLC.

Therefore, the Internet information is superimposed on the distribution line 24 that penetrates the distribution line through hole PT1 of each indoor / outdoor partition wall 3W. In -n, the amount of power and the Internet information can be obtained by the common in-house distribution line 24. Accordingly, in order to enable Internet communication at each home 3, 3-2, 3-n, a conventional through hole PT2 for an Internet communication line as shown in FIG. No construction is required. Furthermore, the transmission terminal 25 has a configuration in which a high-speed PLC slave unit 251 and an adapter 253 for meter reading data signal system are housed, and a high-speed PLC device master unit (HA master unit) 252 for home use is also housed.

以上のように、本実施の形態１のような多機能化した伝送端末器２５を用いることによりシステム構築コスト、機器を設置するための工事費用等の削減ができる。さらに通信機能付電力量計の近傍で検針用高速ＰＬＣモデムと宅内用高速ＰＬＣモデムを中継することにより、設備工事コストを最小限に留めながらＰＬＣ信号強度を保つことで、効率的にインタネット通信速度を確保できる。また、家庭内と各家庭メータ収納室間は配電線のみで、新たな通信線は不要であり、容易にシステムを構築することが可能となる。 As described above, by using the multi-function transmission terminal 25 as in the first embodiment, it is possible to reduce the system construction cost, the construction cost for installing the equipment, and the like. In addition, by relaying the high-speed PLC modem for meter reading and the high-speed PLC modem for home use in the vicinity of the watt-hour meter with communication function, the PLC signal strength is maintained while minimizing the cost of equipment construction. Can be secured. Further, only a distribution line is provided between the home and each home meter storage room, and no new communication line is required, so that a system can be easily constructed.

本実施の形態３は、伝送端末器２５を、宅内用高速ＰＬＣ機器親機２５２をユニット化し伝送端末器２５に着脱可能とした伝送端末器２５とした事例である。 The third embodiment is an example in which the transmission terminal 25 is a transmission terminal 25 in which the home high-speed PLC device base unit 252 is unitized and detachable from the transmission terminal 25.

具体的には、図３において、宅内用高速ＰＬＣ機器親機２５２は、その一部が伝送端末器２５に収納されているが、伝送端末器２５に着脱可能に取り付けられており、宅内用高速ＰＬＣ機器親機２５２と電力量計２６の負荷側電力量計端子台２６Ｔ２との間の配電線２４は伝送端末器２５の外側に配設されている。すなわち、宅内用高速ＰＬＣ機器親機２５２を内蔵したい場合は、伝送端末器２５に内蔵可能であり、宅内用高速ＰＬＣ機器親機２５２が不要な場合には伝送端末器２５から取り外すことが可能な構成となっている。 Specifically, in FIG. 3, a part of the home high-speed PLC device base unit 252 is housed in the transmission terminal 25, but is detachably attached to the home terminal high-speed PLC device 252. A distribution line 24 between the PLC device main unit 252 and the load-side watt-hour meter terminal block 26T2 of the watt-hour meter 26 is disposed outside the transmission terminal 25. That is, when it is desired to incorporate the home high-speed PLC device master 252, it can be built into the transmission terminal 25, and when the home high-speed PLC device master 252 is not necessary, it can be detached from the transmission terminal 25. It has a configuration.

電力会社が設置する自動検針機能部は集合住宅全軒に設置する必要があり、設置しないと電力量の計量値を読むため設置しない家に検針員が訪問する必要が発生するため非常に効率が悪い。一方、各家庭のインタネットは希望の家庭のみが使用料金を支払って導入するシステムであり、希望しない家庭には宅内系高速ＰＬＣ機能は不要となる。本実施の形態３はこのような２種類の対応に対し効率よく経済的なシステムを供給する観点から発明されたものであり、伝送端末器２５の宅内用高速ＰＬＣ機器親機２５２を着脱式にし、インタネットが必要な家庭には宅内用高速ＰＬＣ機器親機２５２を実装した伝送端末器２５を設置し、インタネットが不要な家庭であれば宅内用高速ＰＬＣ機器親機２５２を実装しない伝送端末器２５を設置することが可能となる。また、当初インタネット機能が不要であった家庭でも将来インタネット機能を追加することも考えられ、この場合は宅内用高速ＰＬＣ機器親機２５２のみを追加で伝送端末器２５に実装可能であり、必要最小限のユニットコストのみで増設工事が対応可能であり非常に効率的で経済的なシステムの供給が可能となる。 The automatic meter reading function set up by the electric power company must be installed in all apartment buildings, and if not installed, the meter reading needs to be visited at the house where the meter is not installed to read the measured electric energy. bad. On the other hand, the Internet of each home is a system in which only a desired home pays a usage fee, and a home high-speed PLC function is not required for a home not desired. The third embodiment was invented from the viewpoint of supplying an efficient and economical system for these two types of correspondences. The home high-speed PLC device base 252 of the transmission terminal 25 is made detachable. A transmission terminal 25 in which a home high-speed PLC device base unit 252 is installed is installed in a home where the Internet is required, and a transmission terminal unit 25 in which the home high-speed PLC device base unit 252 is not installed in a home where the Internet is not required. Can be installed. In addition, it is conceivable to add an Internet function in the future even in a home where the Internet function is not required at the beginning. In this case, only the high-speed PLC device for home use 252 can be additionally mounted on the transmission terminal 25, and the minimum necessary Expansion work can be handled with only a limited unit cost, and a very efficient and economical system can be supplied.
