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.

Claims

1. 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.

2. The processing method of data according to claim 1,

wherein the model list of the management server further stores information storage destinations of the data corresponding to the model names, and the method further comprising:

receiving a model name from a user terminal, and semantic information indicating a state of the model name;

selecting a information storage destination and data to be monitored by referring to the model list based on the model name,

deciding a condition of data to be monitored by referring to the semantic interpretation list based on the semantic information; and

storing the monitoring object and the condition in the event table.

3. The processing method of data according to claim 1, further comprising:

receiving data including identifiers from the sensor nodes;

extracting the identifiers from data received from the sensor nodes;

searching the event table for the condition, based on the extracted identifiers, and

comparing the searched condition with the data to determine whether the condition is satisfied, and

generating an event, when the condition is satisfied.

4. The processing method of data according to claim 2, further comprising:

providing a first action table that stores in advance processing performed when the condition is satisfied, correspondingly to the identifiers, and

performing processing stored in the first action table, based on the identifiers, when the event generator generates an event.

5. The processing method of data according to claim 2, further comprising:

processing the data when processing stored in the first action table is processing that processes data transmitted from the sensor nodes, and

adding an identifier to the processed data.

6. The processing method of data according to claim 4, further comprising:

receiving a model name from a user terminal, and semantic information indicating a state of the model name;

selecting an information storage destination and data to be monitored by referring to the model list based on the model name;

deciding a condition of data to be monitored by referring to the semantic interpretation list based on the semantic information;

sending the selected monitoring object and the decided condition to the information storage destination,

notifying the processing to be executed, based on a request from the user terminal, and

setting the processing to be executed in the first action table based on the notification.

7. The processing method of data according to claim 3, further comprising:

providing a first action table in which file names of files describing processing to be executed are specified correspondingly to the identifiers;

providing a second action table that stores the files describing the processing to be executed, and

executing processing of files stored in the second action table, based on file names stored in the first action table based on the identifiers.

8. The processing method of data according to claim 7, further comprising:

comparing the condition with the data in place of the event condition parser to determine whether the condition is satisfied, when executing a file stored in the second action table; and

deciding processing to be executed when the condition is satisfied.
