Description

本発明は、エネルギーを管理するエネルギー管理システムに関する。   The present invention relates to an energy management system for managing energy.

一般に、学校、病院、中規模工場といったビル設備のエネルギー管理業務において、法律の改正により従来なかった省エネ管理およびその国への報告義務が課せられるようになった。そのため、当該ビル用にもエネルギー管理システムおよび専門の管理技術者の配置が必要となり、エネルギー管理コストの増大が避けられない状況になってきた。   In general, in the energy management work of building facilities such as schools, hospitals, and medium-sized factories, the revision of the law has imposed an unprecedented energy conservation management and reporting obligation to the country. For this reason, it is necessary to arrange an energy management system and a specialized management engineer for the building, and an increase in energy management cost is inevitable.

このような要望に答えるものとして、従来、省エネルギーサービスのための顧客データを管理システムに取り込み、そのデータに基づく省エネルギーサービス対価計算手段を提供し、システム導入前後のコスト低減よりサービス対価を計算する手段と各設備が最適条件で運転されている場合のエネルギーコストを算出する事ができ、またエネルギー使用量についても同様に比較出来るシステムが知られている(例えば、特許文献1参照)。   In response to such demands, conventionally, customer data for energy-saving services is taken into the management system, energy-saving service consideration calculation means based on the data is provided, and service consideration is calculated from cost reduction before and after system introduction. In addition, there is known a system that can calculate the energy cost when each piece of equipment is operated under optimum conditions, and can also compare the amount of energy used in the same manner (for example, see Patent Document 1).

また、他の従来の技術として、各エネルギー需要者のエネルギー消費状況の計測データを管理システムに取り込み、人数、使用電気製品のエネルギー消費特性、設定条件といった需要者属性情報を用い、属性が同類需要者との比較によりエネルギー使用状況を分析する方法、装置、およびそのサービスを提供する事業者が存在する場合のシステムも知られている(例えば、特許文献2参照)。
特開2001−282889号公報(段落番号0040−0053、図1) 特開2003−316922号公報(段落番号0016−0024、図1−6)
As another conventional technology, the measurement data of the energy consumption status of each energy consumer is taken into the management system, and the customer attribute information such as the number of people, the energy consumption characteristics of the electric appliances used, and the setting conditions is used. A method, an apparatus for analyzing an energy usage situation by comparison with a person, and a system in the case where there is a provider providing the service are also known (see, for example, Patent Document 2).
JP 2001-282889 A (paragraph number 0040-0053, FIG. 1) JP 2003-316922 A (paragraph number 0016-0024, FIG. 1-6)

上記従来技術のエネルギー管理システムでは、大規模施設および棟の管理を目的としており、顧客の1つの施設、棟におけるエネルギー供給装置単位でのデータ分析は可能であったが、顧客の所有する複数の施設、棟からなるビル群を管理する場合には、専門員が複数のビルに赴き、エネルギー情報を当該サイトの管理システムから取得、あるいは管理システムが無い場合は個々の監視対象のエネルギー監視装置からエネルギー情報を測定装置により自動で読み取っていたため、ビル群全体のエネルギー情報の現在データを把握するのが困難であった。また、個別に集計したエネルギー計測値を統計処理する場合は、管理装置への人手による入力処理が必要であったため、専門員の作業負担が大きく手間取るため、現時点での統計情報を把握するのが困難であった。また専門員が必要な事からコスト面も高くなっていた。   The above-mentioned energy management system of the prior art is intended for managing large-scale facilities and buildings, and it was possible to analyze data in units of energy supply units in one facility and building of the customer. When managing a building group consisting of facilities and buildings, specialists go to multiple buildings and obtain energy information from the management system at the site, or from individual energy monitoring devices when there is no management system. Since energy information was automatically read by a measuring device, it was difficult to grasp current data of energy information of the entire building group. Also, when statistically processing individually measured energy measurement values, manual input processing to the management device was necessary, so the work load of the specialist is large, so it is necessary to grasp the current statistical information It was difficult. Also, the cost was high due to the need for specialists.

また従来のエネルギー管理システムでは、各エネルギー計測値を計測した結果の統計情報を閲覧するためには、各施設、棟単位で専用のコンピューター装置、および表示装置、印刷装置等が必要になり、非常にコストが高くなる問題があった。   In addition, the conventional energy management system requires a dedicated computer device, display device, printing device, etc. for each facility and building unit in order to view statistical information on the results of measuring each energy measurement value. There is a problem that the cost becomes high.

本発明の目的は、顧客の所有するビル群における各種エネルギー計測データの測定、各種エネルギー計測データを自動収集して一括管理すると共に専門員の巡回作業を廃し、安価なサービスを可能としたエネルギー管理システムを提供することにある。   The purpose of the present invention is to measure various energy measurement data in a group of buildings owned by a customer, collect all energy measurement data automatically and manage them collectively, and eliminate the patrol work of specialists, enabling energy-saving services To provide a system.

上記目的を達成するため、本発明では、複数の顧客ビルで使用する電気、ガス、油、水等の各種のエネルギー関連データを取得して管理するエネルギー管理システムにおいて、前記顧客ビルに設けられ前記各種エネルギーデータを収集する端末装置と、この端末装置と通信回線を介して接続し、前記端末装置で収集した各種のエネルギーデータを集計、計算して統計データとして保存するデータセンターと、このデータセンターと通信回線を介して接続し、前記データセンターで保存する統計データを読出し、エネルギー消費報告書を作成する顧客エネルギー管理部とから構成したことを特徴とする。   In order to achieve the above object, in the present invention, in an energy management system for acquiring and managing various energy-related data such as electricity, gas, oil and water used in a plurality of customer buildings, the customer building is provided with the A terminal device that collects various energy data, a data center that is connected to the terminal device via a communication line, collects and calculates various energy data collected by the terminal device, and stores it as statistical data, and this data center And a customer energy management unit that reads out statistical data stored in the data center and creates an energy consumption report.

このように構成したため、複数施設および棟からなるビル群を所有する顧客よりビル群の管理を委託されている管理会社は、顧客に義務付けられている各種エネルギー使用量計測データの取得および、管轄の役所への報告に必要な処理、さらに顧客への省エネ情報提供等のための当該ビル群の集計データ算出、また統計処理、およびグラフ化を効率的に行い、顧客が所有するビル群の施設や棟の各サイトに、エネルギー管理システムを置く事も、エネルギー計測、集計のための専門員を置く必要がなくなり、設備費用、人件費の削減につながる。また一方、顧客は所有するビル群のエネルギー管理情報を専用のコンピューター装置を必要とせず、顧客が通常業務で使用のパーソナルコンピューターとインターネット回線のみが有れば入手出来るため、エネルギー管理のための費用削減を図る事ができる。   Because of this configuration, the management company entrusted with the management of the building group by the customer who owns the building group consisting of multiple facilities and buildings acquires various energy usage measurement data required by the customer and Efficiently perform processing necessary for reporting to government offices, calculate aggregate data for the building group to provide energy-saving information to customers, etc., statistical processing, and graphs, etc. Placing an energy management system at each site in the building eliminates the need for specialists for energy measurement and aggregation, leading to reductions in equipment costs and labor costs. On the other hand, the energy management information of the buildings owned by the customer does not require a dedicated computer device, and can be obtained if the customer has only a personal computer and an internet connection used for normal business. Reduction can be achieved.

本発明によれば、顧客の所有するビル群における各種エネルギー計測データの測定、各種エネルギー計測データを自動収集して一括管理すると共に専門員の巡回作業を廃し、安価なサービスを提供することができる。   According to the present invention, measurement of various energy measurement data in a building group owned by a customer, automatic collection of various energy measurement data and collective management, and the traveling work of specialists can be eliminated, and an inexpensive service can be provided. .

以下、本発明の実施形態を図面に基づき説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.
