Abstract

A sensor net system including: a sensor node which includes: a sensor which obtains sensor data of a worker; a radio frequency circuit which notifies a server of the sensor data; and a server which includes: a relation list for correlating the sensor data with work status of the worker; a unit for confirming the work status of the worker based on the obtained sensor data by using the relation list; a unit for displaying the confirmed work status on a display unit connected to the server.

Claims

1. A sensor net system comprising:

a plurality of sensor nodes, where each sensor node is held on a person of a differing worker, and each sensor node includes;

a sensor which obtains sensor data of a worker;

a radio frequency circuit which notifies a server of the sensor data; and

a server which includes;

a unit for storing a relation list for correlating the sensor data with a work category of the worker;

a unit for confirming a coworker who works together with the worker based on a plurality of obtained sensor data; and

a unit for confirming a work category in which the worker and the coworker are engaged based on the confirmed coworker and the relation list.

2. The sensor net system as claimed in claim 1, wherein

confirmed work categories for the worker are graphically shown in chronological order on a display unit connected to the server.

3. The sensor net system as claimed in claim 1, wherein

a location where the worker and coworker are engaged in the work category, is displayed on a display unit connected to the server.

4. The sensor net system as claimed in claim 1, wherein

work barometer when the worker is engaged in the work category is displayed on a display unit connected to the server.

5. The sensor net system as claimed in claim 4, wherein

the work barometer is a degree of activity or a speech frequency.

6. The sensor net system as claimed in claim 1, wherein

the server further has a unit for storing an interest list for storing a keyword related to the each of workers in a correlative manner, and

if a keyword extracted in relation to the worker coincides with the keyword correlated with the coworker included in the interest list, the server notifies the worker of information on the coworker.

7. The sensor net system as claimed in claim 1, wherein

the server further has a unit for storing an interest list for storing a keyword related to the each of workers in a correlative manner, and

if a keyword extracted in relation to the worker coincides with the keyword correlated with the coworker included in the interest list, the server notifies the coworker of information on the worker.

8. A sensor net system comprising:

a plurality of sensor nodes, where each sensor node is held on a person of a differing worker, and each sensor node includes;

a sensor which obtains sensor data of a worker on whom it is held; and

a radio frequency circuit which notifies a server of the sensor data; and

a server which includes;

a unit for storing a relation list for correlating the sensor data with a work category of the worker;

a unit for confirming another worker who is working near the worker, based on a plurality of sensor data;

a unit for confirming a work category in which the worker and the another worker are engaged, based on the confirmed another worker and the relation list.

9. The sensor net system as claimed in claim 8, wherein

a location where the worker and the another worker are engaged in the work category, is displayed on a display unit connected to the server.

10. The sensor net system as claimed in claim 8, wherein

a degree of activity or a speech frequency of the worker is displayed on a display unit connected to the server.
