Abstract
A processing method of data transmitted from sensor nodes, including: providing a model list that stores preset model names; providing a semantic interpretation list that stores semantic information corresponding to a value of the data; providing an event table that stores monitoring conditions of values of data corresponding to the model names; receiving data corresponding to the model names from the sensor nodes; notifying an occurrence of an event when receiving data satisfying the monitoring conditions from the sensor nodes; and executing processing previously specified when an occurrence of an event is notified.
Claims17
A processing method of data transmitted from sensor nodes, comprising:
- providing a model list that stores preset model names;
- providing a semantic interpretation list that stores semantic information corresponding to a value of the data;
- providing an event table that stores monitoring conditions of values of data corresponding to the model names;
- receiving data corresponding to the model names from the sensor nodes;
- notifying an occurrence of an event when receiving data satisfying the monitoring conditions from the sensor nodes;
- and
- executing processing previously specified when an occurrence of an event is notified.
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
- the distributed servers comprise:
- an event table that stores monitoring conditions of values of the data corresponding to the model names;
- an event action controller including an event generator that receives data corresponding to the model names from the sensor nodes and generates an event when receiving data satisfying the monitoring conditions from the sensor nodes, and a first action executer that executes first processing previously specified based on an occurrence of the event.
