Description

この発明は、Ｗｅｂ機能を用いてビル設備の状態監視及び操作を行うビル管理システムに関するものである。   The present invention relates to a building management system for monitoring and operating a building facility using a Web function.

従来、この種のビル管理システムにおいて、テナント別に設備の監視及び操作項目を制限する必要がある場合に、テナント毎にＷｅｂページを用意してテナント特定のＵＲＬ（Uniform Resource Locator）をアクセスする方式のものがある。   Conventionally, in this type of building management system, when it is necessary to limit facility monitoring and operation items for each tenant, a web page is prepared for each tenant and a tenant-specific URL (Uniform Resource Locator) is accessed. There is something.

また、利用者識別コードの他にアクセスする端末構成情報によるチェックを介入させることにより利用者識別コードが第三者に漏洩した場合でも機密情報の漏洩を防止するものがある（例えば、特許文献１参照）。さらに、電子証明書を用いてインターネットに接続可能にするものがある（例えば、特許文献２参照）。   In addition, there is an apparatus that prevents leakage of confidential information even when the user identification code is leaked to a third party by intervening a check based on terminal configuration information to be accessed in addition to the user identification code (for example, Patent Document 1). reference). Furthermore, there is one that enables connection to the Internet using an electronic certificate (see, for example, Patent Document 2).

特開平１１−３２８１２０号公報（第３頁）JP 11-328120 A (page 3) 特開２００２−２１７８９９号公報（第２頁）JP 2002-217899 A (second page)

しかしながら、テナント毎にＷｅｂページを用意してテナント特定のＵＲＬをアクセスする方式のものは、他のテナントが当該テナントのＵＲＬを知ると、他のテナントからもアクセス可能になるという欠点があった。また、上述した端末構成情報として、パスワードを用い、ＵＲＬへのアクセスをパスワードによって制限する場合があるが、パスワードによるセキュリティレベルはあまり高いものとは言えない。すなわち、ユーザ名やパスワードによるユーザ識別では高いセキュリティ性が期待できず、ユーザ側でもパスワードを入力する手間が生じることになる。   However, the method of preparing a Web page for each tenant and accessing a tenant-specific URL has a drawback that when another tenant knows the URL of the tenant, the tenant can also access it. Further, there is a case where a password is used as the terminal configuration information described above and access to the URL is restricted by the password, but the security level by the password is not very high. In other words, high security cannot be expected by user identification using a user name or a password, and the user has to input a password.

この発明は上述した点に鑑みてなされたもので、デジタル証明書をベースとしてユーザを特定し、不正アクセスの防止とユーザの設備管理レベルに応じた監視及び操作を可能にすることができるビル管理システムを提供することを目的とする。   The present invention has been made in view of the above-described points, and it is possible to specify a user based on a digital certificate, and to enable building management capable of preventing unauthorized access and monitoring and operating according to the user's facility management level. The purpose is to provide a system.

この発明に係るビル管理システムは、ビル内の設備を監視及び操作するビル管理装置と、前記ビル管理装置とＩＰ網を介して接続される設備操作用端末と、前記設備操作用端末に、拡張情報として前記ビル管理装置が監視及び操作する設備とその管理レベルが予め記憶されたデジタル証明書を配布すると共に、前記ビル管理装置に利用者登録を行うアクセス管理センターとを備え、前記ビル管理装置は、ユーザに応じて監視及び操作する設備種別とその設備名を予め記憶したユーザ情報テーブルを有し、前記設備操作用端末からのアクセス時に前記デジタル証明書から証明者名の会社名と氏名とを抽出し、前記ユーザ情報テーブルを参照して、利用権限のある設備の操作メニューを生成して前記設備操作用端末に操作メニューの画面を表示させるものである。   The building management system according to the present invention is extended to a building management apparatus that monitors and operates facilities in a building, a facility operation terminal connected to the building management apparatus via an IP network, and the facility operation terminal The building management apparatus includes an equipment that is monitored and operated by the building management apparatus and a digital certificate in which the management level is stored in advance, and an access management center that performs user registration in the building management apparatus. Has a user information table that pre-stores the equipment type to be monitored and operated according to the user and the equipment name, and the company name and name of the prover name from the digital certificate when accessed from the equipment operation terminal, Referring to the user information table, an operation menu for equipment with authority to use is generated and an operation menu screen is displayed on the equipment operation terminal. Is shall.

この発明のビル管理システムによれば、デジタル証明書をベースとしてユーザを特定し、不正アクセスの防止とユーザの設備管理レベルに応じた監視及び操作を可能にすることができる。   According to the building management system of the present invention, it is possible to identify a user based on a digital certificate, and to prevent unauthorized access and monitor and operate according to the user's facility management level.

図１は、この発明の実施の形態に係るビル管理システムの全体構成を示すブロック図である。図１に示すように、アクセス管理センター１とパーソナルコンピュータでなるユーザの設備操作用端末２は、ＩＰ網３を介して監視及び操作対象ビルのビル管理装置５に接続されている。   FIG. 1 is a block diagram showing the overall configuration of a building management system according to an embodiment of the present invention. As shown in FIG. 1, an access management center 1 and a user equipment operation terminal 2 composed of a personal computer are connected to a building management apparatus 5 of a building to be monitored and operated via an IP network 3.

アクセス管理センター１は、ユーザからの利用申込みに応じてデジタル証明書を発行すると共に、ビル管理装置４に対して利用者登録を行い、登録後は、ユーザ（アクセス管理者）に対して登録通知を行いユーザの設備操作用端末２にデジタル証明書を配布する。設備操作用端末２は、配布されたデジタル証明書を用いてビル管理装置４にアクセスすることで、ビル管理装置４により基本認証が行われ、その認証に基づいてアクセス権に応じた操作画面が送信されるようになされている。なお、監視及び操作対象ビルは、Ａビルの他、Ｂビル、Ｃビル、Ｄビル等複数のビルを監視及び操作対象とすることができる。   The access management center 1 issues a digital certificate in response to a use application from a user, and performs user registration with the building management apparatus 4. After registration, the user (access manager) is notified of registration. The digital certificate is distributed to the user equipment operation terminal 2. The facility operation terminal 2 accesses the building management apparatus 4 using the distributed digital certificate, whereby the building management apparatus 4 performs basic authentication, and an operation screen corresponding to the access right is displayed based on the authentication. It is supposed to be sent. Note that the building to be monitored and operated can be the object to be monitored and operated in addition to the A building, such as a B building, a C building, and a D building.

図２は、デジタル証明書の内容を示すものである。図２に示すデジタル証明書は、ＩＴＵ（International Telecommunications Union：国際電気通信連合電気通信標準化部門）が定めたデジタル証明書の標準仕様であるX.509v3という書式に従うもので、アクセス管理センター１により、証明書の基本情報となるバージョン情報、証明書番号、署名アルゴリズム、証明書の証明者情報、証明書有効期限、証明書が証明する対象の情報としての証明者（本人）名、証明書に含まれる公開鍵情報、この証明書を使って何が証明できるかの情報が書き込まれるVer.2の拡張情報、Ver.3の拡張情報、証明書発行局である認証局の署名が予め書き込まれて、各設備操作用端末２に配布される。   FIG. 2 shows the contents of the digital certificate. The digital certificate shown in FIG. 2 conforms to the format of X.509v3, which is a standard specification of a digital certificate defined by the ITU (International Telecommunications Union). Version information that is basic information of the certificate, certificate number, signature algorithm, certificate certifier information, certificate expiry date, name of the certifier (person) as information to be certified, and included in the certificate Public key information to be written, information about what can be proved using this certificate, Ver.2 extended information, Ver.3 extended information, and the certificate authority's certificate authority's signature are written in advance , Distributed to each equipment operation terminal 2.

ここで、デジタル証明書の証明者（本人）名の欄には、例えば会社名と氏名が記載される。また、Ver.3の拡張情報の欄には、図３に示すように、拡張フィールド識別子の欄に、ビル管理装置４が監視及び操作する設備種目が状態参照か発停制御かのいずれかの情報と共に書き込まれ、解釈の必須度欄には必須か非必須かの情報が書き込まれ、拡張フィールドの値の欄には、管理レベルとして、拡張フィールド識別子の欄に書き込まれた設備に対する状態参照と発停制御のいずれかの情報を「許可」とするのかまたは「非許可」とするのかの管理レベルが書き込まれて設定されている。   Here, for example, the company name and name are described in the column of the name of the prover (person) of the digital certificate. Further, as shown in FIG. 3, the extended information column of Ver. 3 includes, in the extended field identifier column, whether the facility type monitored and operated by the building management apparatus 4 is state reference or start / stop control. It is written together with the information, information on whether it is required or not required is written in the compulsory level column, and in the extended field value column, as a management level, the status reference for the facility written in the extended field identifier column is stored. A management level is written and set as to whether any of the start / stop control information is “permitted” or “not permitted”.

また、図４は、前記ビル管理装置４に予め格納されるユーザ情報テーブルを示す図である。図４に示すように、ユーザ情報テーブルには、ユーザの「会社名」と「氏名」、これに応じて監視及び操作する「設備種別」とその具体的な「設備」が予め記憶されており、ビル管理装置４は、設備操作用端末２からのアクセス時にデジタル証明書から証明者名の「会社名」と「氏名」とを抽出し、前記ユーザ情報テーブルを参照して、利用権限のある設備の操作メニューを生成して設備操作用端末２に操作メニューの画面を表示させるようになされている。   FIG. 4 is a diagram showing a user information table stored in advance in the building management apparatus 4. As shown in FIG. 4, in the user information table, the “company name” and “name” of the user, the “equipment type” to be monitored and operated in accordance with this, and the specific “equipment” are stored in advance. The building management apparatus 4 extracts “certificate name” and “name” from the digital certificate at the time of access from the equipment operation terminal 2, refers to the user information table, and has authority to use. An equipment operation menu is generated and an operation menu screen is displayed on the equipment operation terminal 2.

ビル管理装置４により生成される操作メニューとして、図５に示すように、操作メニューには、「１Ｆ照明ａ」の設備に対して、「ＯＮ」と「ＯＦＦ」操作釦が表示され発停制御の権限が与えられ、「３Ｆ空調ａ」の設備に対して、状態がＯＦＦであることのみが表示され参照のみの権限が与えられる。このようにして、管理レベルに応じて操作メニューに表示する設備項目の表示形態を変えることができる。   As the operation menu generated by the building management apparatus 4, as shown in FIG. 5, the operation menu displays “ON” and “OFF” operation buttons for the equipment of “1F illumination a”, and start / stop control. Is granted, and only the fact that the state is OFF is displayed for the equipment of “3F air conditioning a”, and the authority of reference only is given. In this way, the display form of equipment items displayed on the operation menu can be changed according to the management level.

次に、上記構成を備えるビル管理システムの動作について図５に示すタイムチャートを参照して説明する。まず、ユーザの設備操作用端末２は、ブラウザから設備操作用ＵＲＬを指定し、事前に配布されたデジタル証明書を提出することで、ＩＰ網３を介して監視対象ビルのビル管理装置４にアクセス要求する。   Next, the operation of the building management system having the above configuration will be described with reference to the time chart shown in FIG. First, the facility operation terminal 2 of the user designates the facility operation URL from the browser and submits a digital certificate distributed in advance to the building management apparatus 4 of the monitored building via the IP network 3. Request access.

ビル管理装置４は、提出されたデジタル証明書がアクセス許可になっているか否かをチェックする。チェック結果、ＮＧの場合は、アクセス非許可を表示するＷｅｂ表示ページを生成し、設備操作用端末２に送信する。他方、提出されたデジタル証明書が事前に利用者登録されたものと一致しチェック結果ＯＫとなった場合には、当該デジタル証明書中の証明者（本人）名の欄に記載されているユーザの「会社名」と「氏名」等を抽出すると共に、図３に示すVer.3の拡張情報を抽出し、図４に示すユーザ情報テーブルを参照して、デジタル証明書に記載されているユーザの利用権限をチェックし、設備操作用端末２に表示させる図３に示す操作メニューを生成する。そして、生成された操作メニューのＷｅｂ表示ページをＩＰ網３を介して設備操作用端末２に送信して表示させる。   The building management apparatus 4 checks whether or not the submitted digital certificate is permitted to be accessed. If the result of the check is NG, a Web display page that displays access denial is generated and transmitted to the equipment operation terminal 2. On the other hand, if the submitted digital certificate matches the one registered in advance and the check result is OK, the user listed in the column of the prover (person) name in the digital certificate "Company name" and "name" etc. are extracted, and Ver.3 extended information shown in FIG. 3 is extracted, and the user described in the digital certificate is referred to the user information table shown in FIG. 3 is checked, and an operation menu shown in FIG. 3 to be displayed on the equipment operation terminal 2 is generated. Then, the generated web display page of the operation menu is transmitted to the equipment operation terminal 2 via the IP network 3 and displayed.

例えば、図３に示すデジタル証明書中のVer.3の拡張情報の例には、拡張フィールド識別子の欄に記載された「空調設備（状態参照）」、「電源設備（状態参照）」、「照明設備（状態参照）」のみが対応する拡張フィールドの値の欄に「許可」となっており、これらの設備項目について当該デジタル証明書のユーザに利用権限が与えられている。   For example, in the example of the extended information of Ver. 3 in the digital certificate shown in FIG. 3, “air conditioner (state reference)”, “power supply facility (state reference)”, “ Only the “lighting equipment (see status)” is “permitted” in the value field of the corresponding extended field, and the user of the digital certificate is given authority to use these equipment items.

さらに、図４には利用権限が与えられた設備種目の具体的な設備名が設定されていて、例えば、「会社名」が「Ａ社」、「氏名」が「Ｚ氏」のユーザに対しては、空調の設備項目の具体的な設備名として、「１Ｆ−１」、「１Ｆ−２」が、電源の設備項目の具体的な設備名として、「１Ｆ−ＣＢ１」が、照明の設備項目の具体的な設備名として、「１Ｆ−１」「１Ｆ−２」がそれぞれ設定されており、これら具体的な設備名に対して状態参照が可能な操作メニューが生成される。   Furthermore, in FIG. 4, a specific equipment name of the equipment type to which the use authority is given is set. For example, for a user whose “company name” is “Company A” and whose “name” is “Mr. Z” In particular, “1F-1” and “1F-2” are the specific equipment names of the air conditioning equipment items, and “1F-CB1” is the lighting equipment equipment as the specific equipment names of the power supply equipment items. “1F-1” and “1F-2” are respectively set as specific facility names of items, and an operation menu capable of referring to the state for these specific facility names is generated.

なお、図３では、操作メニューとして状態参照部分だけが生成されているが、例えば、図３に示すデジタル証明書中のVer.3の拡張情報の例において、拡張フィールド識別子の「空調設備（発停制御）」に対応する拡張フィールドの値の欄に「許可」が与えられている場合、つまり発停制御の権限が与えられる場合には、例えば、図５に示すように、操作メニューには、「１Ｆ照明ａ」の設備に対して、「ＯＮ」と「ＯＦＦ」操作釦が表示され発停制御の権限が与えられ、「３Ｆ空調ａ」の設備に対して、状態がＯＦＦであることのみが表示され参照のみの権限が与えられるようにしてもよい。このようにして、管理レベルに応じて操作メニューに表示する設備項目の表示形態を変えることができる。   In FIG. 3, only the state reference portion is generated as the operation menu. For example, in the example of the extended information of Ver. 3 in the digital certificate shown in FIG. When “permitted” is given in the value field of the extended field corresponding to “stop control)”, that is, when the right of start / stop control is given, for example, as shown in FIG. , “ON” and “OFF” operation buttons are displayed for the equipment of “1F lighting a”, and the authority of start / stop control is given, and the state of the equipment of “3F air conditioning a” is OFF. Only may be displayed and the authority of reference only may be given. In this way, the display form of equipment items displayed on the operation menu can be changed according to the management level.

このようにして、ビル管理装置４により、利用権限がある設備のみ操作できるメニューがＷｅｂ表示ページとして生成され、設備操作用端末２に送信されて、設備操作用端末２に設備操作メニューの画面が表示される。   In this way, the building management device 4 generates a menu that can be operated only by the facility for which the user has authority to use as a Web display page, is transmitted to the facility operation terminal 2, and the facility operation menu screen is displayed on the facility operation terminal 2. Is displayed.

この発明によれば、デジタル証明書をベースにしてユーザを特定し、ユーザの管理レベルに応じた監視及び操作が可能な設備項目のみをメニュー表示することができ、不正アクセスの防止及びメニュー表示の制限に対応できる。   According to the present invention, a user can be specified based on a digital certificate, and only the equipment items that can be monitored and operated according to the management level of the user can be displayed in a menu. Can handle restrictions.
