In addition, when presenting a list of the estimated power consumption per appliance to a user, the power consumption estimation device refers to an installation location database (350) in which the installation locations of the appliance operating sound monitoring means (120) that detected the changes in the appliance operating sounds are registered, and presents the power consumption per appliance as well as the installation locations to the user.

Description

消費電力推定装置、消費電力推定システム、消費電力推定方法および消費電力推定プログラムを格納した非一時的なコンピュータ可読媒体Non-transitory computer-readable medium storing power consumption estimation apparatus, power consumption estimation system, power consumption estimation method, and power consumption estimation program
　本発明は、消費電力推定装置、消費電力推定システム、消費電力推定方法および消費電力推定プログラムを格納した非一時的なコンピュータ可読媒体に関し、特に、各機器が発する動作音を用いて、多様な機器の動作状況を推測し、それを基に各機器の消費電力量を推定する消費電力推定装置、消費電力推定システム、消費電力推定方法および消費電力推定プログラムを格納した非一時的なコンピュータ可読媒体に関する。 The present invention relates to a power consumption estimation device, a power consumption estimation system, a power consumption estimation method, and a non-transitory computer-readable medium storing a power consumption estimation program, and in particular, various devices using operation sounds generated by each device. The present invention relates to a power consumption estimation device, a power consumption estimation system, a power consumption estimation method, and a non-transitory computer readable medium storing a power consumption estimation program. .
　従来の家庭内の電気機器の消費電力の測定方式に関しては、配電盤に測定器を設置することによって、家庭全体の電力消費量の推移を測定して、ユーザにその情報を提示する方式や、コンセントに測定器を設置し、コンセント単位で電力消費量を測定し、ユーザにその情報を提示する方式がある。 With regard to conventional methods for measuring the power consumption of electrical equipment in the home, a measuring instrument is installed on the switchboard to measure the transition of the power consumption of the entire home and present the information to the user. There is a method in which a measuring instrument is installed in the terminal, the power consumption is measured in units of outlets, and the information is presented to the user.
　配電盤に測定器を設置する方式の場合、家庭全体のすべての電気機器（以下、「機器」と略称する）の総電力消費量しか分からず、機器単位での電力消費状況が不明である。また、コンセントに測定器を設置する方式の場合、コンセント単位での設置が必要なため設置コストが高くなるとともに、コンセント単位でしか電力消費量が分からない。さらには、コンセントに接続している機器を変更した場合や、コンセントの先にさらに延長コンセントを接続して、さらに複数の機器が接続されている場合も想定され、機器単位の詳細な消費電力量を把握することが困難である。 In the case of a method in which a measuring instrument is installed on a switchboard, only the total power consumption of all electrical devices in the entire home (hereinafter referred to as “device”) is known, and the power consumption status in units of devices is unknown. In addition, in the case of a method in which a measuring instrument is installed in an outlet, the installation cost is increased because the installation is required in units of outlets, and the power consumption is known only in units of outlets. In addition, when the equipment connected to the outlet is changed, or when an extension outlet is connected to the end of the outlet and more than one equipment is connected, detailed power consumption for each equipment is assumed. It is difficult to grasp.
　特許文献１の特開２００３-９４３０号公報「遠隔電気機器監視方法および装置並びにそれを利用した消費電力測定方法および装置」には、配電盤に設置された電力測定装置を用いて、配電盤を流れる総負荷電流を測定し、測定した総負荷電流を基本波並びに高調波成分に変換してから、変換した基本波並びに高調波成分ごとの時間変化差分を用いて、稼働中の機器を特定し、機器単位の電力消費量を推定する技術が開示されている。 Japanese Patent Application Laid-Open No. 2003-9430 “Remote Electric Appliance Monitoring Method and Device and Power Consumption Measurement Method and Device Using the Same” discloses a total power flowing through the distribution board using a power measurement device installed on the distribution board. After measuring the load current, converting the measured total load current into fundamental wave and harmonic components, using the converted fundamental wave and time difference difference for each harmonic component, identify the equipment in operation, and Techniques for estimating unit power consumption are disclosed.
　しかしながら、該特許文献１に記載の技術の問題点としては、総負荷電流の解析のみによって機器単位の消費電力を推定するというものであり、稼働中の機器を特定して、機器単位の電力消費量を推定する際の精度に関しての問題がある。さらに、総負荷電流の変化量の特徴を機器単位に分離することができたとしても、その分離された特徴が、実際に、どの機器に相当するのかを特定するためには、該特許文献１の段落［００２１］、［００２２］に記載されているように、機器固有の動作特性モデルの情報を各機器ごとの消費電力特性情報として事前に保持しておくことが必要になる。その際、全く同一種別の機器が複数個存在している場合には、どちらの機器が動作して電力を消費しているかを判別することができない。 However, the problem of the technique described in Patent Document 1 is that the power consumption in units of equipment is estimated only by analyzing the total load current. There is a problem with accuracy when estimating quantities. Furthermore, even if the feature of the amount of change in the total load current can be separated for each device, in order to specify which device the separated feature actually corresponds to, Patent Document 1 As described in paragraphs [0021] and [0022] of the above, it is necessary to hold in advance information on the operation characteristic model unique to the device as power consumption characteristic information for each device. At this time, if there are a plurality of devices of the same type, it is not possible to determine which device is operating and consuming power.

　以上のように、現状の消費電力の推定技術においては、機器単位の消費電力推定手段として、高コストの機器単位の電力測定装置の設置もしくは各機器の消費電力特性情報等の事前の準備が必要であるという点に問題がある。 As described above, in the current power consumption estimation technique, it is necessary to install a high-cost power measurement device for each device or to prepare in advance such as power consumption characteristic information of each device as a device-based power consumption estimation means There is a problem in that.

　（４）本発明による消費電力推定プログラムを格納した非一時的なコンピュータ可読媒体は、少なくとも前記（３）に記載の消費電力推定方法を、コンピュータに実行させるを特徴とする。 (4) A non-transitory computer-readable medium storing a power consumption estimation program according to the present invention is characterized by causing a computer to execute at least the power consumption estimation method described in (3).
　本発明の消費電力推定装置、消費電力推定システム、消費電力推定方法および消費電力推定プログラムを格納した非一時的なコンピュータ可読媒体によれば、以下のような効果を奏することができる。 According to the non-transitory computer-readable medium storing the power consumption estimation apparatus, power consumption estimation system, power consumption estimation method, and power consumption estimation program of the present invention, the following effects can be obtained.
　第１の効果は、電力消費量や電気機器（以下、「機器」と略称する）の動作状況をモニタリングするための高価な専用機器の機器単位の設置工事が不要になることである。その理由は、機器動作音モニタ手段を家屋内に複数個配置するだけで、家屋内の各機器の動作音の変化を捉え、その動作音の変化情報を基に、各機器の状態変化を推定するように動作することを可能にしているためである。機器動作音モニタ手段は家庭内に設置された機器の数だけ設置する必要はなく、家屋内の複数の部屋それぞれに、１個ないし数個ずつ設置すれば良い。 The first effect is that it is not necessary to install an expensive dedicated device for each device in order to monitor the power consumption and the operation status of an electrical device (hereinafter referred to as “device”). The reason for this is that by simply placing multiple device operation sound monitoring means in the house, changes in the operation sound of each device in the house are captured, and the state change of each device is estimated based on the change information of the operation sound. This is because it makes it possible to operate. It is not necessary to install the device operation sound monitor means by the number of devices installed in the home, and it is sufficient to install one or several devices in each of a plurality of rooms in the home.
　第２の効果は、機器単位の消費電力の推定およびユーザへの情報提示を行う際に、各機器の消費電力特性情報等の事前の準備が不要になることである。その理由は、相関解析手段によって、音を基にして機器動作音モニタ手段が検出した機器の動作状態の変化と、総電力消費量測定記録手段によって測定・記録された総使用電力量の変化との相関を解析して、動作状態の変化と総使用電力量の変化との対応関係を特定し、該当する機器の消費電力量を推定するように動作することを可能にしているためである。 The second effect is that, when estimating the power consumption of each device and presenting information to the user, it is not necessary to prepare in advance the power consumption characteristic information of each device. The reason for this is that the correlation analysis means changes the operating state of the equipment detected by the equipment operating sound monitoring means based on the sound, and the total power consumption measured and recorded by the total power consumption measurement recording means. This is because it is possible to identify the correspondence between the change in the operating state and the change in the total power consumption, and to estimate the power consumption of the corresponding device.
　第３の効果は、多様な機器の動作音データとその動作音を発生させる機器名称との組からなるデータベースを事前に準備する必要もないことである。その理由は、機器動作音モニタ手段は、単純に、各機器が発する機器動作音の特徴の変化だけを捉え、該機器動作音の特徴の変化を該当する機器の動作の変化状況を示す情報として、機器動作変化記録手段を通して記録しているだけで十分であるからである。また、機器単位の消費電力量をユーザに提示する際に、機器ごとの種別や名称、商品名等のデータベースを事前に準備する必要もない。その理由は、機器動作音モニタ手段が検出した動作音と、実際にその動作音を発生させた機器との対応関係をユーザに提示する機器消費電力提示手段としては、機器動作音モニタ手段の設置場所情報を基に、該当する場所に設置されている機器がこれだけの電力を消費している、といったような形式の情報提示を行うだけで、該当する機器の種別、名称、商品名を用いた情報の提示は行わないようにしているためである。かくのごとき提示形式であっても、ユーザは、機器消費電力提示手段が提示している機器と、家屋内に設置されている実際の機器との対応関係を十分に把握することができる。 The third effect is that it is not necessary to prepare in advance a database comprising a set of operation sound data of various devices and device names that generate the operation sounds. The reason for this is that the device operation sound monitoring means simply captures only changes in the features of the device operation sounds emitted by each device, and uses the changes in the features of the device operation sounds as information indicating the change status of the operation of the corresponding device. This is because it is sufficient to record through the device operation change recording means. In addition, when presenting the power consumption of each device to the user, it is not necessary to prepare in advance a database of types, names, product names, etc. for each device. The reason for this is that equipment operating sound monitoring means is installed as equipment power consumption presenting means for presenting the user the correspondence between the operating sound detected by the equipment operating sound monitoring means and the equipment that actually generated the operating sound. Based on the location information, the device type, name, and product name of the applicable device were used simply by presenting information in a format such that the device installed at the relevant location consumes this much power. This is because information is not presented. Even in such a presentation format, the user can sufficiently grasp the correspondence between the device presented by the device power consumption presenting means and the actual device installed in the house.

（本発明の特徴）
　本発明の実施の形態の説明に先立って、本発明の特徴についてその概要をまず説明する。本発明は、電気機器（以下、「機器」と略称する）単位の高コストの電力測定装置が不要で、かつ、各機器の消費電力特性情報の事前の準備を不要とする、機器単位の消費電力推定の仕組みを備えたことを主要な特徴としている。なお、本発明の消費電力推定システムとは、家庭内の機器の消費電力を推定するシステムであり、家庭内の各機器と、各機器へ電力を配電する配電盤または分電盤と、各機器単位の消費電力量を推定し、推定した各機器単位の消費電力量をユーザに提示する消費電力推定装置とから構成されているものである。 (Features of the present invention)
Prior to the description of the embodiments of the present invention, an outline of the features of the present invention will be described first. The present invention eliminates the need for a high-cost power measurement device in units of electrical equipment (hereinafter referred to as “devices”) and eliminates the need for prior preparation of power consumption characteristic information of each device.

　より具体的には、家屋内の複数個所にそれぞれ配置された複数個の機器それぞれが発する機器動作音の変化を検出する機器動作音モニタ手段により各機器の稼働状態の変化を推定するとともに、配電盤に設置された総電力消費量測定記録手段によって総電力使用量の変化を記録し、機器の稼動状態の変化と総使用電力量の変化との両者の変化の相関を相関解析手段によって解析することによって、機器単位の消費電力量を推定する仕組みを備えていることを主要な特徴としている。 More specifically, a change in the operating state of each device is estimated by device operation sound monitoring means for detecting a change in device operation sound emitted by each of a plurality of devices respectively arranged at a plurality of locations in the house, and the switchboard Record the change in total power consumption by the total power consumption measurement and recording means installed in the system, and analyze the correlation between the change in the operating status of the equipment and the change in the total power consumption by the correlation analysis means. The main feature is that it has a mechanism for estimating the power consumption of each device.
　また、推定された機器単位の消費電力量の一覧をユーザに提示する際には、機器動作音の変化を検出する機器動作音モニタ手段それぞれの設置場所の情報を用いて、設置場所ごとの各機器の電力消費量として提示することによって、推定された機器単位の電力消費量と、実際に設置されている機器との対応関係を、ユーザが容易に把握することができる仕組みを備えていることも主要な特徴としている。 In addition, when presenting a list of estimated power consumption for each device to the user, information on each installation location of each device operation sound monitoring means for detecting a change in device operation sound is used. Provide a mechanism that allows the user to easily understand the correspondence between the estimated power consumption of each device and the actually installed device by presenting it as the power consumption of the device Is also a key feature.
　さらに説明すると、本発明の消費電力推定装置は、家屋内に複数個設置された機器動作音モニタ手段と、各機器動作音モニタ手段によって検出された機器動作音の変化を機器動作の変化を示す情報として記録する機器動作変化記録手段と、配電盤に設置され、家屋全体の総使用電力量を測定し記録する総電力消費量測定記録手段と、前記機器動作変化記録手段および前記総電力消費量測定記録手段それぞれによって記録された機器動作の変化と、総使用電流量の変化との両者の相関を解析し、機器単位の消費電力量の推定を行う相関解析手段とを備えている。 More specifically, the power consumption estimation apparatus according to the present invention shows a change in device operation by a plurality of device operation sound monitoring means installed in the house and a change in device operation sound detected by each device operation sound monitor means.

　さらに、本発明の消費電力推定装置は、各機器動作音モニタ手段の設置場所の情報を用いて、前記相関解析手段によって推定された機器単位の消費電力量および現在の推定動作状態を、場所情報を付与した上でユーザに提示する、機器消費電力提示手段を備えている。 Furthermore, the power consumption estimation apparatus of the present invention uses the information on the installation location of each device operation sound monitor means to calculate the power consumption amount and the current estimated operation state of each device estimated by the correlation analysis means as location information. Is provided with a device power consumption presentation means for presenting to the user.
　以上のような構成により、本消費電力推定装置上の各手段は次のように動作する。複数の部屋に設置された、それぞれ１ないし複数個の機器動作音モニタ手段は、各機器動作音モニタ手段に接続されたマイクからの音声入力データを常時モニタし、何らかの機器動作音の変化を検出すると、機器動作変化記録手段を用いて、動作音変化の種類、変化発生時間およびその変化を捉えた機器動作音モニタ手段の識別コード等からなる機器動作の変化を示す機器状態変化情報として随時記録していく。 With the above configuration, each means on the power consumption estimation apparatus operates as follows. One or a plurality of device operation sound monitoring means installed in a plurality of rooms constantly monitor voice input data from microphones connected to each device operation sound monitoring means to detect any change in device operation sound.

FIG. 2 is a flowchart illustrating an example of an operation flow of the power consumption estimation apparatus according to the first embodiment illustrated in FIG. 1. FIG. 3 is a sequence diagram illustrating an example of exchange of various types of information in the power consumption estimation apparatus according to the first embodiment illustrated in FIG.
　センサ装置１００～１０Ｎは家屋内の複数個所に設置され、各センサ装置１００～１０Ｎの機器動作音モニタ手段１２０は、本機器動作音モニタ手段１２０に接続されたマイク１１０からの音声入力データを常時モニタし、機器動作音の変化がないか監視している（図２、図３のステップＡ１）。センサ装置１００～１０Ｎの設置箇所に関しては、家屋内の各部屋に１つずつ配置しても良いし、各部屋に複数個ずつ配置し、それぞれを各部屋内の異なる場所に配置するようにしても良い。 The sensor devices 100 to 10N are installed at a plurality of locations in the house, and the device operation sound monitoring means 120 of each sensor device 100 to 10N always receives the voice input data from the microphone 110 connected to the device operation sound monitoring means 120. Monitoring is performed to check whether there is a change in the device operating sound (step A1 in FIGS. 2 and 3). As for the installation locations of the sensor devices 100 to 10N, one may be arranged in each room in the house, or a plurality of sensors are arranged in each room, and each is arranged in a different place in each room. Also good.
　センサ装置１００～１０Ｎにはそれぞれ一意に特定することが可能な識別コードが付与されており、センサ装置１００～１０Ｎの識別コード（すなわち機器動作音モニタ手段１２０それぞれをユニークに特定することが可能な識別コード）と、センサ装置１００～１０Ｎの設置場所情報（すなわち機器動作音モニタ手段１２０の設置場所情報）との組が、解析装置３００の設置場所データベース３５０に格納されている。センサ装置１００～１０Ｎの設置場所情報の例としては、緯度経度情報でも良いし、「会議室１」のような部屋名称であっても良いし、または、家屋平面図上のＸＹ座標であっても良い。 Each of the sensor devices 100 to 10N is provided with an identification code that can be uniquely specified, and the identification code of the sensor devices 100 to 10N (that is, each of the device operation sound monitoring means 120 can be uniquely specified). A set of the identification code) and the installation location information of the sensor devices 100 to 10N (that is, the installation location information of the device operation sound monitoring means 120) is stored in the installation location database 350 of the analysis device 300. Examples of the installation location information of the sensor devices 100 to 10N may be latitude / longitude information, a room name such as “conference room 1”, or XY coordinates on the house plan view. Also good.
　機器動作音モニタ手段１２０は、機器動作音の変化を検出すると、検出した機器動作音の変化情報を、送信モジュール１３０を用いて、解析装置３００の受信モジュール３１０宛に送信する（図２、図３のステップＡ２）。機器動作音の変化の例としては、機器のスイッチ押下音の発生や、モータやファン動作音の発生もしくは停止、機器が発する電子音の発生等が挙げられる。 When the device operation sound monitoring unit 120 detects a change in the device operation sound, the device operation sound monitoring unit 120 transmits the detected change information of the device operation sound to the reception module 310 of the analysis device 300 using the transmission module 130 (FIGS. 2 and 2). 3 step A2). Examples of changes in device operating sound include generation of switch pressing sound of a device, generation or stop of motor or fan operation sound, generation of electronic sound generated by the device, and the like.
　また、これらの機器動作音の変化の解析方法としては、音圧レベルを監視し、音圧レベルの短時間での急激な変化（増加もしくは減少）を機器動作音の変化として捉える方法や、周波数解析を行い特定周波数のみに着目してその急激な変化もしくは特定周波数のレベルが一定時間以上連続して継続しているといった解析を行う方法、また、あらかじめ準備された代表的な音データベースとのパターンマッチング解析を行う、といった方法が例として挙げられる。 In addition, as a method of analyzing the change in device operation sound, the sound pressure level is monitored, and a rapid change (increase or decrease) in the sound pressure level in a short time is recognized as a change in device operation sound. Analyzing and analyzing only a specific frequency and analyzing the abrupt change or the level of a specific frequency continuously for a certain time or more, and a pattern with a typical sound database prepared in advance An example is a method of performing matching analysis.
　音圧レベルの解析手法を用いると、音の発生、停止を捉え易く、周波数解析を用いた手法を用いると、特定種類の音（モータ、ファン、人の声）の発生、停止および連続した再生状態を識別し易い。また、音データベースとのパターンマッチング手法を用いると、準備した音データベースに応じて多様な種類の動作音の識別が可能になる。一方で、音データベースに用いる音データの量を増やすと、音データベースの構築に手間が掛かるので、ここでは、汎用的に利用可能な動作音のみを音データベースとして準備することを想定している。 Using the sound pressure level analysis method, it is easy to detect the occurrence and stop of sound, and using the method using frequency analysis, the generation, stop and continuous playback of a specific type of sound (motor, fan, human voice) It is easy to identify the state. Further, when a pattern matching method with a sound database is used, various types of operation sounds can be identified according to the prepared sound database. On the other hand, if the amount of sound data used in the sound database is increased, it takes time to construct the sound database. Here, it is assumed that only operation sounds that can be used for general purposes are prepared as the sound database.
　以上のように、機器動作音の変化の解析手法によって得意とする検出対象の機器動作音が異なるため、今回の機器動作音モニタ手段１２０の代表的な実装例としては、図４に示すように、複数の音解析手段を並列に備えた構成を想定しており、それぞれが得意なタイプの機器動作音の検出を行い、検出結果を出力する。図４は、図１に示す第１の実施の形態の消費電力推定装置における機器動作音モニタ手段１２０のブロック構成例を示すブロック図である。 As described above, since the device operation sound to be detected is different depending on the analysis method of the change in the device operation sound, a typical implementation example of the device operation sound monitoring unit 120 of this time is as shown in FIG. A configuration in which a plurality of sound analysis means are provided in parallel is assumed, each of which detects a type of device operation sound that is good at each, and outputs a detection result. FIG. 4 is a block diagram illustrating a block configuration example of the device operation sound monitoring unit 120 in the power consumption estimation apparatus according to the first embodiment illustrated in FIG. 1.
　図４に示す機器動作音モニタ手段１２０の構成においては、複数の音解析手段の一例として音圧解析手段１２１、周波数解析手段１２２、音パターンマッチング手段１２３の３種類の機器動作音の変化の解析手段を備え、マイク１１０からの音声データ入力を機器動作音モニタ手段１２０内の機器動作音の変化の各解析手段に並行して入力する例を示しており、機器動作音の変化の解析手段のいずれかにて機器動作音の変化を検出した場合には、その旨を検出結果として出力する。 In the configuration of the device operation sound monitoring unit 120 shown in FIG. 4, analysis of changes in three types of device operation sounds, a sound pressure analysis unit 121, a frequency analysis unit 122, and a sound pattern matching unit 123, as an example of a plurality of sound analysis units. And a voice data input from the microphone 110 is input to each of the device operating sound change analyzing means in the device operating sound monitoring unit 120 in parallel. If any change in device operating sound is detected, this is output as a detection result.
　機器動作音変化の検出結果は、動作音変化の種類名称、変化発生時間およびその変化を捉えた機器動作音モニタ手段１２０が搭載されているセンサ装置１００～１０Ｎの識別コード（すなわち該当の機器動作音モニタ手段１２０をユニークに特定する識別コード）を含む。 The detection result of the device operation sound change includes the type name of the operation sound change, the change occurrence time, and the identification code of the sensor devices 100 to 10N equipped with the device operation sound monitoring means 120 that captures the change (that is, the corresponding device operation sound). Including an identification code for uniquely identifying the sound monitoring means 120.
　機器動作音変化の種類名称の一例としては、例えば、音圧解析手段１２１が、音圧の変化に関して、あらかじめ定めた一定時間以下の短時間内であらかじめ定めた音圧閾値以上に音圧が上昇したことを検出した場合は、「音圧上昇」、該一定時間以下の短時間内で該音圧閾値以上の上昇と元のレベルに戻る現象とが発生したことを検出した場合は、「音圧上下降」、また、周波数解析手段１２２があらかじめ定めた周波数閾値以上の高周波数の音声があらかじめ定めた一定継続時間以上に継続したことを検出した場合は、「高周波数継続」といった種類名称を付すことが挙げられる。 As an example of the type name of the device operation sound change, for example, the sound pressure analysis means 121 increases the sound pressure above a predetermined sound pressure threshold within a short time of a predetermined time with respect to the change of the sound pressure. If it is detected that the sound pressure has risen, the sound pressure threshold is increased within a short period of time less than the predetermined time, and the phenomenon of returning to the original level occurs. If the frequency analysis means 122 detects that a high-frequency sound equal to or higher than a predetermined frequency threshold has continued for a predetermined duration or longer, a type name such as “high-frequency continuation” is used. It is mentioned.
　ここで、機器動作音変化の種類名称それぞれは、必ずしも、実際の機器の動作名称例えば「炊飯器スイッチオン」、「エアコンモータ作動中」との一対一の対応までは行わないことにしている。その理由は、ここで挙げた機器動作音モニタ手段１２０の各種音解析手段のみでは、実際の機器の動作まで特定する能力を備えていないためである。なお、本実施の形態においては、後述する相関解析手段３４０における総電力消費量との相関解析および設置場所データベース３５０を用いた機器設置場所の特定および機器消費電力提示手段３６０によるユーザへの提示方式を採用することにより、ユーザが、直感的にどの機器に関しての情報であるのかを把握し易いようにすることによって補うことにしている。 Here, each type name of the device operation sound change is not necessarily performed in a one-to-one correspondence with an actual device operation name, for example, “rice cooker switch on” or “air conditioner motor in operation”. The reason is that only the various sound analysis means of the equipment operation sound monitoring means 120 mentioned here do not have the ability to specify the actual operation of the equipment. In the present embodiment, a correlation analysis with total power consumption in correlation analysis means 340, which will be described later, a device installation location using installation location database 350, and a presentation method to the user by device power consumption presentation means 360 are shown. By adopting the above, it is made up by making it easy for the user to grasp intuitively which device the information is about.
　かくのごとく、現実の機器動作との一対一の対応および特定を行わないことにより、既存技術で必要とされた、機器単位の消費電力特性情報や、個別の動作音データベース等が不要になるという効果が得られる。 As described above, by not performing one-to-one correspondence and identification with actual device operation, it is unnecessary to use power consumption characteristic information for each device, individual operation sound database, and the like, which are required in the existing technology. An effect is obtained.
　また、機器動作音モニタ手段１２０の設置場所および家屋内の機器の設置場所、機器の種別によっては、複数の機器の動作音が一つの機器動作音モニタ手段１２０にて検出されてしまい、今回検出した音がいずれの機器が発した音かを特定することができない状況も発生し得る。この点に関しても、機器動作音モニタ手段１２０における機器動作音の変化のみによる検出の段階においては、該当する機器の分離、特定を実施しないままにして、解析装置３００の機器動作変化データベース３３０に随時記録していく。そして、後述する相関解析手段３４０における総電力消費量との相関解析によって、機器ごとの使用電力状況の分離を可能にしている。 In addition, depending on the installation location of the device operation sound monitoring unit 120, the installation location of the device in the house, and the type of device, the operation sound of a plurality of devices may be detected by one device operation sound monitoring unit 120, which is detected this time. There may be a situation where it is not possible to specify which device the generated sound is. Also in this regard, in the stage of detection based on only the change in the device operation sound in the device operation sound monitoring means 120, the device operation change database 330 of the analysis apparatus 300 is stored as needed without separating and specifying the corresponding device. Record it. Then, by using a correlation analysis with the total power consumption in the correlation analysis unit 340 described later, it is possible to separate the power usage status for each device.
　図２のフローチャート、図３のシーケンス図に戻って、解析装置３００の受信モジュール３１０にて受信したセンサ装置１００～１０Ｎからの機器動作音変化の検出結果は、機器動作変化記録手段３２０によって機器動作変化データベース３３０に機器状態変化情報として記録、蓄積されていく（図２、図３のステップＡ３）。ここで、機器状態変化情報は、機器動作音検出結果の情報であり、前述したように、具体的には、機器動作音変化の種類名称、変化発生時間およびその変化を捉えた機器動作音モニタ手段１２０が搭載されているセンサ装置１００～１０Ｎの識別コード（すなわち該当の機器動作音モニタ手段１２０をユニークに特定する識別コード）を含む。 Returning to the flowchart of FIG. 2 and the sequence diagram of FIG. 3, the detection result of the device operation sound change from the sensor devices 100 to 10N received by the reception module 310 of the analysis device 300 is detected by the device operation change recording unit 320. It is recorded and accumulated as device state change information in the change database 330 (step A3 in FIGS. 2 and 3). Here, the device state change information is information on the device operation sound detection result, and specifically, as described above, the device operation sound change type name, the change occurrence time, and the device operation sound monitor that captures the change. The identification code of the sensor devices 100 to 10N on which the means 120 is mounted (that is, the identification code that uniquely identifies the corresponding device operation sound monitoring means 120) is included.
　また、機器動作音モニタ手段１２０の機器動作音の変化の検出動作と並行して、総電流記録装置２００の総電力消費量測定記録手段２２０は、家屋の配電盤に設置された配電盤メータ２１０の情報を常時読み取り、家屋内の総使用電力量の変化を総電力消費量データベース２４０に随時記録している（図２、図３のステップＡ４）。ここで、本実施の形態においては、家屋全体の配電盤に、１個、総電流記録装置２００を設置することを想定しているが、分電盤ごとに、総電流記録装置をそれぞれ設置することによって、分電盤単位の消費電力量を個別に記録する構成であっても良い。 In parallel with the detection operation of the change in the device operation sound of the device operation sound monitoring unit 120, the total power consumption measurement recording unit 220 of the total current recording device 200 is information on the switchboard meter 210 installed in the switchboard of the house. Is constantly recorded, and changes in the total power consumption in the house are recorded in the total power consumption database 240 as needed (step A4 in FIGS. 2 and 3). Here, in this embodiment, it is assumed that one total current recording device 200 is installed on the distribution board of the entire house, but the total current recording device is installed for each distribution board. Therefore, a configuration may be used in which the power consumption amount for each distribution board is individually recorded.
　機器動作変化記録手段３２０によって機器状態変化情報が機器動作変化データベース３３０に記録されると、次に、解析装置３００の相関解析手段３４０が起動され、相関解析手段３４０は、機器動作変化記録手段３２０によって機器動作変化データベース３３０に記録された機器状態変化情報を取得し（図２、図３のステップＡ５）、さらに、総電流記録装置２００の総電力消費量測定記録手段２２０によって総電力消費量データベース２４０に記録された総使用電力量の変化情報の取得を行う（図２、図３のステップＡ６）。ここで、総電流記録装置２００の総電力消費量データベース２４０に記録された総使用電力量の変化情報の取得の際には、相関解析手段３４０の要求を総電流記録装置２００に送出することによって、総電流記録装置２００の総電力消費量データベース２４０に記録された総使用電力量の変化情報が、送信モジュール２３０および受信モジュール３１０を通して、相関解析手段３４０に送信されてくる。 When the device state change information is recorded in the device operation change database 330 by the device operation change recording unit 320, the correlation analysis unit 340 of the analysis apparatus 300 is started next, and the correlation analysis unit 340 is connected to the device operation change recording unit 320. To acquire the device state change information recorded in the device operation change database 330 (step A5 in FIG. 2 and FIG. 3), and further, the total power consumption measurement database 220 of the total current recording device 200 performs the total power consumption database. The change information of the total power consumption recorded in 240 is acquired (step A6 in FIGS. 2 and 3). Here, when acquiring the change information of the total power consumption recorded in the total power consumption database 240 of the total current recording device 200, the request of the correlation analysis means 340 is sent to the total current recording device 200. The change information of the total power consumption recorded in the total power consumption database 240 of the total current recording device 200 is transmitted to the correlation analysis unit 340 through the transmission module 230 and the reception module 310.
　得られた両者の変化情報を、相関解析手段３４０にて相関解析することによって、機器状態変化情報と、総使用電力量の変化情報との対応関係を特定し、機器単位の電力消費量を推定する（図２、図３のステッブＡ７）。相関解析手段３４０における相関解析の実施手順の具体例については、図５のフローチャートを用いて後述する。 Correlation analysis is performed on the obtained change information by the correlation analysis unit 340, thereby identifying the correspondence between the device state change information and the change information of the total power consumption, and estimating the power consumption for each device. (Step A7 in FIGS. 2 and 3). A specific example of the procedure for performing the correlation analysis in the correlation analysis unit 340 will be described later with reference to the flowchart of FIG.
　相関解析手段３４０にて機器単位の電力消費量を推定すると、次に、機器消費電力提示手段３６０を起動して、推定された消費電力量をユーザに提示する手順に進む。機器消費電力提示手段３６０は、相関解析手段３４０によって推定された機器単位の電力消費量をユーザに提示する際に、機器動作変化データベース３３０にあらかじめ記録されている機器状態変化情報に含まれている該当状態変化を捉えた機器動作音モニタ手段１２０の識別コード（すなわちセンサ装置１００～１０Ｎの識別コード）と、設置場所データベース３５０に格納された当該識別コードと設置場所との対応情報とを用いることによって、場所情報も含めた上で、機器単位の電力消費量情報をユーザに提示する（図２、３のステップＡ８）。 If the correlation analysis means 340 estimates the power consumption for each device, the device power consumption presentation means 360 is then activated to proceed to a procedure for presenting the estimated power consumption to the user. The device power consumption presentation unit 360 is included in the device state change information recorded in advance in the device operation change database 330 when presenting the power consumption of each device estimated by the correlation analysis unit 340 to the user. Use the identification code of the device operation sound monitoring means 120 that captures the change in the state (that is, the identification code of the sensor devices 100 to 10N) and the correspondence information between the identification code stored in the installation location database 350 and the installation location. Thus, the power consumption information for each device is presented to the user after including the location information (step A8 in FIGS. 2 and 3).
　推定された消費電力量のユーザへの提示の具体例を挙げると次の通りである。例えば、機器動作音モニタ手段１２０が、リビング、ダイニング、子供部屋、寝室、キッチン、浴室のそれぞれの部屋に設置されていたとする。かかる場合には、解析装置３００の設置場所データベース３５０には、各部屋それぞれに設置された各機器動作音モニタ手段１２０それぞれの識別コードと対応付けられた形式で、「リビング」、「ダイニング」、「子供部屋」、「寝室」、「キッチン」、「浴室」といった設置場所に関する情報が格納されている。 A specific example of presenting the estimated power consumption to the user is as follows. For example, it is assumed that the device operation sound monitoring means 120 is installed in each of a living room, a dining room, a children's room, a bedroom, a kitchen, and a bathroom. In such a case, the installation location database 350 of the analysis apparatus 300 includes “living room”, “dining room”, “dining room”, and the like in a format associated with each identification code of each device operation sound monitoring unit 120 installed in each room. Information on the installation location such as “child's room”, “bedroom”, “kitchen”, and “bathroom” is stored.
　機器消費電力提示手段３６０は、設置場所データベース３５０の設置場所に関する情報と、相関解析手段３４０によって得られた消費電力量に関する情報とを基にして、「リビング」の機器Ａは本日１８：００に起動されて２０：００に終了、その間の消費電力量は１０ＯＷ、同じく、「リビング」の機器Ｂは１５：００に起動されて、現在も起動中、時間単位の消費電力量は１０ＯＷ／ｈ、「寝室」の機器Ｃは、２１：００に起動されて、２２：００に終了、その間の消費電力量は４００Ｗといったように、各設置場所における、機器単位の稼動情報および消費電力情報を提示する。 The device power consumption presenting means 360 uses the information on the installation location in the installation location database 350 and the information on the power consumption obtained by the correlation analysis means 340 for the device A of “living room” at 18:00 today. It is activated and ends at 20:00, and the power consumption during that time is 10 OW. Similarly, the “Living” device B is activated at 15:00 and is still active, and the power consumption per hour is 10 OW / h. The device C in the “bedroom” is activated at 21:00, ends at 22:00, and presents operation information and power consumption information for each device at each installation location such that the power consumption during that time is 400 W. .
　かくのごとく、本実施の形態においては、各機器の具体的な種別や名称、例えば、電子レンジやエアコン等までの特定を実施することなく、機器消費電力提示手段３６０によって提示された設置場所と消費電力量との情報を基にして、ユーザ自身で実際の機器を判断することを想定している。なお、設置場所と各機器の具体的な種別や名称との対応関係を、ユーザがあらかじめ登録することにし、機器消費電力提示手段３６０は、該当の設置場所に登録された機器の名称を検索して、検索した機器の名称をユーザに提示するという仕組みを採用するようにしても良い。 As described above, in the present embodiment, the specific location and the name of each device, for example, the installation location presented by the device power consumption presenting means 360 without specifying the microwave oven, the air conditioner, etc. It is assumed that the user himself / herself determines the actual device based on the information on the power consumption. Note that the correspondence between the installation location and the specific type and name of each device is registered in advance by the user, and the device power consumption presentation unit 360 searches for the name of the device registered in the installation location. Thus, a mechanism of presenting the searched device name to the user may be adopted.
　次に、相関解析手段３４０における相関解析の実施手順の具体例については、図５のフローチャートを用いて詳細に説明する。図５は、図１に示す第１の実施の形態の消費電力推定装置における相関解析手段３４０の相開解析処理の一例を示すフローチャートである。なお、相関解析に用いる要素としては、機器状態変化情報の発生した時間および場所および状態変化の種別、さらに、その時間近傍の電力消費量の変化量を少なくとも含んでいる。また、機器状態変化情報の発生場所としては、その変化情報を捉えた機器動作音モニタ手段１２０が含まれるセンサ装置１０ｉ（ｉ＝０～Ｎ）の識別コード（すなわち該当の機器動作音モニタ手段１２０をユニークに特定する識別コード）を用いる。相関解析の結果としては、電力消費の観点から有意な機器状態変化情報と、それに対応する消費電力量を算出する。 Next, a specific example of the correlation analysis execution procedure in the correlation analysis unit 340 will be described in detail with reference to the flowchart of FIG. FIG. 5 is a flowchart showing an example of the phase opening analysis process of the correlation analysis unit 340 in the power consumption estimation apparatus according to the first embodiment shown in FIG. The elements used for the correlation analysis include at least the time and place where the device state change information is generated, the type of state change, and the amount of change in power consumption near that time. Further, as the place where the device state change information is generated, the identification code of the sensor device 10i (i = 0 to N) including the device operation sound monitoring unit 120 that captures the change information (that is, the corresponding device operation sound monitoring unit 120). Is used to uniquely identify the ID. As a result of the correlation analysis, significant device state change information and a corresponding power consumption amount are calculated from the viewpoint of power consumption.
　図５のフローチャートにおいて、最初の解析手順として、まず、センサ装置１００～１０Ｎの識別コード単位に、機器動作変化データベース３３０に格納されていた機器状態変化情報を分類する（図５のステップＢ１）。次に、機器動作変化データベース３３０に格納されていた識別コード単位ごとのデータ群内の一つ一つの機器状態変化情報ごとに、その状態変化が発生した時間近傍で、総使用電力量の変化が発生したか否かを確認し、機器状態変化情報と、その際の総使用電力量の変化量とを組にした情報を記憶していく（図５のステップＢ２）。 In the flowchart of FIG. 5, as the first analysis procedure, first, the device state change information stored in the device operation change database 330 is classified into the identification code units of the sensor devices 100 to 10N (step B1 in FIG. 5). Next, for each piece of equipment state change information in the data group for each identification code unit stored in the equipment operation change database 330, a change in total power consumption occurs near the time when the state change occurs. Whether or not it has occurred is confirmed, and information that is a combination of the device state change information and the change amount of the total power consumption at that time is stored (step B2 in FIG. 5).
　次に、同一識別コード内の機器状態変化種別とその際の電力変化量との組に着目して、毎回同じ総使用電力量の変化が発生していたか否かの解析を行う（図５のステップＢ３）。より具体的には、同一識別コード内で、同じ機器状態変化種別のデータが複数個存在していた場合に、それぞれの総使用電力量の変化量を比較し、毎回同じ変化が発生していた場合には、当該機器状態変化種別が、消費電力量の変化に関連した動作音であることが分かり、その際の消費電力量の変化量も判明することになる。なお、毎回、正確に同一の変化量を示さなくとも、あらかじめ定めた回数を超える多くのケースで、同様の変化量が発生しているという場合であっても良い。 Next, paying attention to the combination of the device state change type in the same identification code and the power change amount at that time, an analysis is performed as to whether or not the same change in total power consumption has occurred each time (FIG. 5). Step B3). More specifically, when there are multiple pieces of data of the same device state change type in the same identification code, the amount of change in the total power consumption is compared and the same change occurs every time. In this case, it is found that the device state change type is an operation sound related to the change in the power consumption, and the change in the power consumption at that time is also found. Even if the same amount of change is not shown every time, the same amount of change may occur in many cases exceeding a predetermined number of times.
　一方、毎回全くランダムに消費電力の変化量が異なる場合、および、毎回消費電力量の変化が発生していない場合は、当該機器状態変化情報は消費電力量の変化とは関係しない機器動作音であることが推定される。 On the other hand, when the amount of change in power consumption is completely different each time, and when there is no change in power consumption every time, the device state change information is a device operation sound not related to the change in power consumption. It is estimated that there is.
　ここで、
１）当該機器動作音モニタ手段１２０が検出した機器状態変化情報とほぼ同じ時刻に、偶然、他の場所に設置されている機器の動作によって消費電力量が変化した場合、
および、
２）複数個所に設置された複数の機器動作音モニタ手段１２０が同一の機器から発した同一の機器動作音をそれぞれ検出した場合、
といったように、センサ装置１００の識別コード（すなわち搭載している機器動作音モニタ手段１２０をユニークに特定するためのコード）が示す設置場所とは異なる設置場所に配置されている機器から発生した機器状態変化情報の影響を考慮することが必要である。 here,
1) When the power consumption changes by the operation of a device installed in another place by chance at almost the same time as the device state change information detected by the device operation sound monitoring means 120,
and,
2) When a plurality of device operation sound monitoring means 120 installed at a plurality of locations detect the same device operation sound emitted from the same device,
As described above, a device generated from a device arranged at a different installation location from the installation location indicated by the identification code of the sensor device 100 (that is, the code for uniquely identifying the installed device operation sound monitoring means 120). It is necessary to consider the effect of state change information.
　このため、ステップＢ３の処理を同一識別コード内で実施した後に、異なる識別コード間での機器状態変化情報と消費電力量の変化情報との組に関しての解析処理を実施する（図５のステップＢ４）。 For this reason, after performing the process of step B3 within the same identification code, an analysis process is performed on a set of device state change information and power consumption change information between different identification codes (step B4 in FIG. 5). ).
　具体的な解析手順の一例としては、１）の当該機器動作音モニタ手段１２０が検出した機器状態変化情報とほぼ同じ時刻に、偶然、他の場所に設置されている機器の動作によって消費電力量が変化した場合については、ステッブＢ３における同一識別コード内の解析によって、高い確率で、機器状態変化情報と消費電力変化情報との関係が推定することができたものに関しては、他の場所に設置されている機器の動作の影響を消費電力量データから差し引いた上で、再度、ステップＢ３を実行することによって、この影響を排除することができる。 As an example of a specific analysis procedure, the amount of power consumption is caused by the operation of a device installed in another place by chance at almost the same time as the device state change information detected by the device operation sound monitoring unit 120 in 1). As for the case in which the relationship between the device state change information and the power consumption change information can be estimated with high probability by the analysis within the same identification code in step B3, install it elsewhere. This effect can be eliminated by subtracting the influence of the operation of the device being performed from the power consumption data and executing step B3 again.
　なお、高い確率で、機器状態変化情報と消費電力変化情報との関係が推定できたものとは、同じ機器状態変化種別のデータが複数あり、各データそれぞれの組になっている消費電力量の変化情報として、毎回、ほぼ同じ電力変化量を示している場合である。一方、同じ機器状態変化種別の複数個のデータに対して、毎同異なる電力消費量を示している場合には、他の設置場所に配置されている機器の電力消費の影響が含まれているケースが想定される。 It should be noted that the relationship between the device state change information and the power consumption change information with a high probability is that there is a plurality of data of the same device state change type, and the amount of power consumption of each data set. This is a case where almost the same amount of power change is shown each time as the change information. On the other hand, when the same amount of power consumption is shown for a plurality of data of the same device state change type, the influence of the power consumption of devices arranged at other installation locations is included. A case is assumed.
　１）の場合については、かくのごときステップＢ３、Ｂ４の処理を複数繰り返すことによって、さらに、より良く、他の設置場所に配置されている機器による影響を排除することができる。 In the case of 1), by repeating the processes of steps B3 and B4 a plurality of times as described above, it is possible to more effectively eliminate the influence of the devices arranged at other installation locations.
　一方、２）の複数個所に設置された複数の機器動作音モニタ手段１２０が同一の機器の同一の機器動作音をそれぞれ検出した場合については、ステップＢ３の解析結果に関して、異なる識別コードを持ちながら、同じ時刻に発生した同じ機器状態変化種別、同じ消費電力変化を示すデータがあるか否かをチェックすることによって洗い出すことが可能である。この結果として洗い出された同一機器の同一動作音に関しての、異なる識別コードを持った機器動作音モニタ手段１２０間に跨ったデータに関しては、一つのみを残して他のデータを削除する。どのデータを残すべきかの基準に関しては、例えば、各機器動作音モニタ手段１２０にて収集された機器動作音のうち、音量が最も大きい機器動作音を検知した機器動作音モニタ手段１２０の機器状態変化情報に関するデータのみを残すようにしても良い。 On the other hand, when the plurality of device operation sound monitoring means 120 installed at a plurality of locations in 2) detect the same device operation sound of the same device, the analysis result of step B3 has different identification codes. It is possible to find out by checking whether there is data indicating the same device state change type and the same power consumption change that occurred at the same time. As a result, with regard to the data straddling between the device operation sound monitoring means 120 having different identification codes regarding the same operation sound of the same device that has been identified, only one is left and the other data is deleted. With regard to the criteria for which data should be left, for example, the device state of the device operation sound monitoring unit 120 that detects the device operation sound having the highest volume among the device operation sounds collected by each device operation sound monitoring unit 120 You may make it leave only the data regarding change information.
　相関解析の最後のステップとして、同一識別コード内において、ステップＢ４までの解析によって有意な関連があると解析された機器状態変化情報と消費電力量変化情報との組それぞれ同士の関連を解析する（図５のステップＢ５）。この解析の目的は、各機器動作音モニタ手段１２０が検出した機器動作音に、複数の機器の動作音が含まれている場合に、それらを区別して、単一の機器の動作状態の変化、および、その際の消費電力量の変化を取り出すためである。 As the last step of the correlation analysis, in the same identification code, the relationship between each set of the device state change information and the power consumption change information analyzed as having a significant relationship by the analysis up to step B4 is analyzed ( Step B5 in FIG. The purpose of this analysis is to change the operating state of a single device by distinguishing them when the device operating sounds detected by each device operating sound monitoring means 120 include operating sounds of a plurality of devices. This is because a change in power consumption at that time is taken out.
　具体的な関連の解析方法としては、或る機器に関して、電源をＯＮすることにより一定の電力消費が発生し、その後、電源をＯＦＦすることにより電力消費が'０'に戻るといった一連の変化が、同一識別コード内の機器状態変化情報と消費電力量変化との組内に含まれているか否かを洗い出すことにし、これによって、複数機器の動作音が混ざっている場合であっても、それぞれの動作状態の変化およびその際の消費電力の変化を機器単位で切り出すことが可能となる。 As a specific related analysis method, for a certain device, a certain power consumption occurs when the power is turned on, and then the power consumption returns to “0” when the power is turned off. , To determine whether it is included in the set of device status change information and power consumption change in the same identification code, even if the operation sound of multiple devices are mixed, It is possible to cut out the change in the operation state and the change in power consumption at that time in units of devices.
　以上のような相関解析手順が、最も単純な解析手順となるが、機器状態変化情報の発生した時間、場所および状態変化種別、さらに、その時間近傍の電カ使用量の変化量といった要素に対する多様な相関解析手段を用いて、互いの相関を解析し、最終的に、機器状態変化情報と、それに対応する機器単位の消費電力量および現在の動作状態とを推定するようにしても良い。 The correlation analysis procedure as described above is the simplest analysis procedure, but there are a variety of factors such as the time, place and status change type when the device status change information occurred, and the amount of change in power usage near that time. Such correlation analysis means may be used to analyze the correlation between each other, and finally, the device state change information, the corresponding power consumption amount of the device unit and the current operation state may be estimated.

　次に、本第１の実施の形態の効果について説明する。 (Effects of the first embodiment)
Next, the effect of the first embodiment will be described.
　本第１の実施の形態の効果は、電力消費量や機器の動作状況をモニタリングするための高価な専用機器の機器単位の設置工事が不要になることである。その理由は、機器動作音モニタ手段１２０を家屋内に複数個配置するだけで、家屋内の各機器の機器動作音の変化を捉え、その機器動作音の変化情報を基に、各機器の状態変化を推定するように動作することを可能にしているためである。機器動作音モニタ手段１２０は機器の数だけ設置する必要はなく、家屋内の複数の部屋それぞれに、１個ないし数個ずつ設置すれば良い。 The effect of the first embodiment is that it is not necessary to install an equipment unit for an expensive dedicated device for monitoring the power consumption and the operation status of the device. The reason is that by simply arranging a plurality of device operation sound monitoring means 120 in the house, the change in the device operation sound of each device in the house is captured, and the state of each device is determined based on the change information of the device operation sound. This is because it is possible to operate so as to estimate the change. It is not necessary to install the device operation sound monitoring means 120 by the number of devices, and one or several devices may be installed in each of a plurality of rooms in the house.
　また、本第１の実施の形態の別の効果は、機器単位の消費電力の推定およびユーザへの情報提示を行う際に、各機器の消費電カ特性情報等の事前の準備が不要になることである。その理由は、相関解析手段３４０によって、音を基にして機器動作音モニタ手段１２０が検出した機器の動作状態の変化と、総電力消費量測定記録手段２２０によって記録された総使用電力量の変化量との相関から、機器の動作状態変化と総使用電力量の変化との対応関係を特定し、該当機器の消費電力量を推定するように動作することを可能にしているためである。 In addition, another effect of the first embodiment is that when power consumption is estimated for each device and information is presented to the user, prior preparation such as power consumption characteristic information of each device is unnecessary. That is. The reason is that the correlation analysis unit 340 detects a change in the operation state of the device detected by the device operation sound monitoring unit 120 based on the sound, and a change in the total power consumption recorded by the total power consumption measurement recording unit 220. This is because it is possible to identify the correspondence between the change in the operating state of the device and the change in the total power consumption from the correlation with the amount, and to operate so as to estimate the power consumption of the corresponding device.
　さらには、別の効果として、多様な機器の動作音データとその動作音を発生させる機器名称との組からなるデータベースを事前に準備する必要もないことがある。その理由は、機器動作音モニタ手段１２０は、単純に、各機器が発する機器動作音の特徴の変化だけを捉え、機器状態変化情報として機器動作変化記録手段３２０を通して機器動作変化データベース３３０に記録するだけで十分であるからである。つまり、機器状態変化情報として記録した機器動作音モニタ手段１２０が検出した機器動作音の変化と、実際にその機器動作音の変化を発生させた機器との対応関係を機器消費電力提示手段３６０がユーザに提示する際には、当該機器動作音を捉えた機器動作音モニタ手段１２０の設置場所情報を基に、該当の場所に設置されている機器がこれだけ電力を消費している、といったような形式の情報提示を行い、機器の種別、名称、商品名を用いた情報提示は行わないようにしているためである。かくのごとき提示方法であっても、ユーザは、機器消費電力提示手段３６０が提示している機器動作音を発生させた機器と、家屋内に設置されている実際の機器との対応関係を十分に把握することができる。 Furthermore, as another effect, there is a case where it is not necessary to prepare in advance a database comprising a set of operation sound data of various devices and device names that generate the operation sound. The reason is that the device operation sound monitoring unit 120 simply captures only a change in the characteristics of the device operation sound generated by each device and records it as device state change information in the device operation change database 330 through the device operation change recording unit 320. Because it is enough. In other words, the device power consumption presenting means 360 shows the correspondence between the change in the device operation sound detected by the device operation sound monitoring means 120 recorded as the device state change information and the device that actually caused the change in the device operation sound. When presenting to the user, based on the installation location information of the device operation sound monitoring means 120 that captures the device operation sound, the device installed in the corresponding location consumes this much power. This is because information is presented in a format, and information presentation using the device type, name, and product name is not performed. Even in the presentation method like this, the user has sufficient correspondence between the device that has generated the device operation sound presented by the device power consumption presentation unit 360 and the actual device installed in the house. Can grasp.
