An aging environment measurement apparatus measures aging environment data within an oak barrel and transmits the measured aging environment data within the oak barrel to a server, and the aging environment measurement apparatus is mounted in a bung of the oak barrel.

Apparatus and method for measuring aging environment

Provided are a system and method for supporting a logical sensor network (LSN) separate from an actual physical sensor network (PSN) to readily obtain sensing data required by a user or application program in an environment consisting of various types of PSNs. The system includes a metadata database (DB) for storing metadata of a plurality of available PSNs each having a plurality of sensor nodes, a LSN generation module for generating a LSN including one or more PSNs among the PSNs registered in the metadata DB or one or more sensor nodes in the PSNs, and storing metadata of the generated LSN in the metadata DB, a LSN update module for updating the metadata of the LSN including the PSNs or the sensor nodes in the PSNs when a state of the PSNs or the sensor nodes is changed, and a query processing module for, when a query about the LSN is received from an application program, collecting sensing data from the PSNs or the sensor nodes included in the LSN, generating query result data for the LSN using the collected data, and providing the query result data to the application program.
