In order to collect data stored in a specific device, the client X must first search for a service registered in the device data collection device connected to the specific device. The service search (S 300) is performed by transmitting and receiving a service list request and response between the client X and a service relaying device storing the service list 450 registered by the plurality of device data collecting devices. That is, the client X requests the service list from the service relay apparatus connected through the network (S400), and receives the service list stored in the service relay apparatus in response to the request (S 402). The service list includes services registered by a plurality of device data collection devices. Each service includes a service ID for identifying a service, a device ID for a device storing data to be received through the service, and a client (X). It contains interface information that defines a method and communication protocol for accessing the equipment data collection device. The client X receives a service list from the service relay device and selects a device data collection device capable of receiving desired data. That is, the client X selects a service to be received. Referring to the service list 450 of FIG. 4, it is assumed that the selected service is a service A (indicated by underlining) provided by the equipment data collection device A.

The client X selects a service to be received from the received service list 450, and thus, the device data collection device capable of receiving the service is selected. In the next step, the client X requests and receives the metadata 460 to the device data collection device A to select data to be collected from the selected device data collection device A, and receives the received metadata ( Based on step 460, a metadata search step (S 302) for selecting data to collect is performed.

Referring to the metadata retrieval step (S 302) in more detail, the client (X) requests the user authentication and login request to the equipment data collection device (A) to receive the service retrieved from the received service list 450 (S 404) Will be sent. Upon receiving the user authentication request and the login request, the device data collection device A determines whether to accept the user authentication request and the login request of the client X based on the stored user information.

The client X selects the data IDs 1001, 1002, 1003 and 1004 selected through the metadata retrieval step S 302, and the number of selected data IDs 4. G), a data collection plan (DCP) is created (S412) including the collection interval information to receive the data value for the selected data ID, and the created DCP is transmitted to the equipment data collection device (A). As a result, the DCP registration request (S414) is made. Upon receiving the DCP registration request, the device data collection device A stores the received DCP, registers it in the DCP list, and manages it (S416). The initially registered DCP remains inactive. Here, the inactive state refers to a state in which the device data collection device A does not transmit the data value for the data ID defined in the DCP to the client X requesting the DCP registration, and the DCP activation request is received from the client X. It will remain inactive until it exists. There are only two DCPs (DCP Y: DCP registered by the client Y, DCP Z: DCP registered by the client Z) on the DCP list 470 before the DCP requested by the client X for DCP registration is registered. After (X) registers DCP, DCP X registered by client (X) is in an inactive state in DCP list 480.
