First Claim
Patent Images
1. A sensor network system, comprising:
- distributed servers that process data transmitted from sensor nodes; and
a management server connected with the distributed servers through a network,wherein the management server comprises;
a model list that stores preset model names;
a semantic interpretation list that stores semantic information corresponding to a value of the data; and
an event-action controller including an action executer that executes processing previously specified when an occurrence of an event is indicated from the distributed servers, andthe distributed servers comprise;
an event table that stores monitoring conditions of values of data corresponding to the model names; and
an event generator that receives data corresponding to the model names from the sensor nodes, and notifies the management server of an occurrence of an event when receiving data satisfying the monitoring conditions from the sensor nodes.

Abstract
This invention enables to easily retrieve real-time information from a large number of sensors connected to a network. A sensor network system includes data collectors that collect data from plural sensors at a specified cycle, a directory server that manages locations and identifiers of data from the sensors, and an event-action controller that, of the data collected from the sensors, monitors preset data to be monitored, and when the data satisfies a preset monitoring condition, executes preset processing.
