Abstract: Disclosed is a dynamic facility management system that is able to start quickly and monitor a state when various measuring instruments are attached to or removed from the facility to be securely monitored and maintained. The system includes a sensor as a measuring instrument. A measuring instrument reading device, which is a lower level device, transmits a type of the measuring instrument and a purpose of connecting the measuring instrument to a directory server. The directory server generates an instance by referring to class information and generates and registers a relation instance by referring to an inter-class relationship. The directory server transmits the generated instance to related devices on the basis of an inter-instance relationship, and the directory server exchanges facility management data between instances on the basis of the inter-instance relationship.

Abstract: In order to set automatically related software in a facility management system and to start quickly and easily a state monitoring when various measuring instruments are attached to or removed from a facility to be monitored, secured, and maintained, when a sensor which is the measuring instrument is connected, a measuring-instrument reading device which is a lower level device transmits a type of the measuring instrument and a purpose of connecting the measuring instrument to a directory server, the directory server generates an instance by referring to class information and generates and registers a relation instance by referring to an inter-class relationship, the directory server transmits the generated instance to a related devices on the basis of an inter-instance relationship, and the directory server exchanges facility management data between instances on the basis of the inter-instance relationship.
