Zusammenfassung: | PROBLEM TO BE SOLVED: To inexpensively and efficiently connect a device where communication protocols for a management network such as BACnet are not installed, to the management network.SOLUTION: An adapter device 2 receives, from each of indoor devices 3a for operations connected to a device network 9, a model publication message including an object being a set of properties into which a function provided by the indoor device 3a for operations is modeled (in S11), stores the object in the model publication message (received in S11) into a device DB 21, and transmits a device entry message including the object stored in the device DB 21 and an address of a management network 8 which is assigned to the indoor device 3a for operations so as to be unequivocal in the management network 8, to a management device 1 via the management network 8 (in S13), thereby registering the indoor device 3a for operations with the management device 1 as a device in the management network 8.SELECTED DRAWING: Figure 2
【課題】BACnetなどの管理網の通信プロトコルを搭載していない機器を、低コストかつ効率的に管理網に接続させること。【解決手段】アダプタ装置2は、機器網9に接続される各業務用室内機3aから、その業務用室内機3aが提供する機能をモデル化したプロパティの集合体であるオブジェクトを含むモデル公開メッセージ(S11)を受信し、モデル公開メッセージ(S11)内のオブジェクトをデバイスDB21に格納し、デバイスDB21に格納されたオブジェクトと、業務用室内機3aに対して管理網8内で一意になるように割り当てた管理網8のアドレスとを含む機器参入メッセージ(S13)を、管理網8を介して管理装置1に送信することで、管理網8のデバイスとして業務用室内機3aを管理装置1に登録させる。【選択図】 図2 |
