Abstract

A work content analyzing apparatus of the present embodiment includes a first database storing state information indicating a state of each of one or a plurality of workers in association with time information and identification information of the worker, an estimation unit estimating the work content executed by the worker on the basis of at least two pieces of state information associated with same time in the state information stored in the first database, a specification unit specifying work time spent for the estimated work content on the basis of the state information stored in the first database and the time information associated with the state information, and an analysis unit analyzing the work content on the basis of the estimated work content and the specified work time.

First claim

The invention claimed is:

1. A work content analyzing apparatus analyzing work content of a worker on the basis of a state of the worker, the apparatus comprising:
at least one sensor attached to or installed around the worker to monitor the state of the worker and to output state information indicating the state of each of the worker or a plurality of workers in association with time information and identification information of the worker;
a first database storing the state information indicating the state of each of the worker or the plurality of workers in association with the time information and identification information of the worker, the state information including at least any one of positional information of the worker, motion information indicating whether a hand of the worker is moving or not, and information indicating an operating state of an equipment around the worker;
a determination unit determining whether the work content analyzing apparatus is operating with a required performance or not;
a processing unit storing first fixed data as the state information in the first database when the determination unit determines that the work content analyzing apparatus is operating with the required performance, and storing second fixed data as the state information in the first database when the determining unit determines that the work content analyzing apparatus is not operating with the required performance, in the case where no state information can be acquired;
an estimation unit estimating the work content executed by the worker on the basis of at least two pieces of state information associated with same time in the state information stored in the first database, the work content including indicating whether the worker is doing work or is not doing work;
a specification unit specifying work time spent for each estimated work content indicating whether the worker is doing work or is not doing work on the basis of the state information stored in the first database and the time information associated with the state information;
an analysis unit analyzing the work content on the basis of the estimated work content and the specified work time; and
a display to graphically display an output of the analysis unit.

2. The work content analyzing apparatus analyzing work content of a worker on the basis of a state of the worker, the apparatus comprising:
at least one sensor attached to or installed around the worker to monitor the state of the worker and to output state information indicating the state of each of the worker or a plurality of workers in association with time information and identification information of the worker;
a first database storing the state information indicating the state of each of the worker or the plurality of workers in association with the time information and identification information of the worker, the state information including at least any one of positional information of the worker, motion information indicating whether a hand of the worker is moving or not, and information indicating an operating state of an equipment around the worker;
a processing unit acquiring second state information by executing averaging and/or majority decision processing for one or a plurality of pieces of first state information in the pieces of the state information, and storing the first state information indicating a plurality of pieces of position information in a short period and the second state information in the first database;
an estimation unit estimating the work content executed by the worker on the basis of a least two pieces of state information associated with same time in the state information stored in the first database, the work content including indicating whether the worker is doing work or is not doing work;
a specification unit specifying work time spent for each estimated work content indicating whether the worker is doing work or is not doing work on the basis of the state information stored in the first database and the time information associated with the state information;
an analysis unit analyzing the work content on the basis of the estimated work content and the specified work time; and
a display to graphically display an output of the analysis unit.

3. The work content analyzing apparatus according to claim 1 or 2 , wherein the first database stores information of the sensor in association with identification information of the worker to which the sensor is attached or identification information of the worker existing within a predetermined distance from a place in which the sensor is installed.

4. The work content analyzing apparatus according to claim 1 or 2 , further comprising:
a second database storing standard time determined in advance for each of the work contents; and
a work time comparison unit comparing the specified work time with the corresponding standard time for the estimated work content.

5. The work content analyzing apparatus according to claim 4 , wherein a result of the comparison includes a difference between the work time and the corresponding standard time or a ratio of the work time to the corresponding standard time.

6. The work content analyzing apparatus according to claim 5 , further comprising:
a display control unit displaying the difference or the ratio for each of the work contents.

7. The work content analyzing apparatus according to claim 5 , wherein the analysis unit further analyzes the work content of the worker on the basis of the difference or the ratio.

8. The work content analyzing apparatus according to claim 1 or 2 , further comprising:
a display control unit displaying an analysis result acquired with the analysis unit.

9. The work content analyzing apparatus according to claim 8 , wherein
the specification unit further specifies a time period corresponding to the estimated work content on the basis of the state information stored in the first database, and
the display control unit displays a work result diagram displaying the work content on a time axis as the analysis result on the basis of the specified time period.

10. The work content analyzing apparatus according to claim 1 or 2 , wherein
each of the workers belongs to any of groups into which each of the workers is classified in advance,
the identification information includes group information designating the group to which the worker belongs,
the estimation unit estimates the work content executed by the group on the basis of at least two pieces of state information associated with same time in state information stored in the first database for the workers belonging to same group,
the specification unit specifies work time spent for the estimated work content on the basis of the state information stored in the first database for the workers belonging to the same group, and
the analysis unit analyzes the work content of the group on the basis of the estimated work content and the specified work time.

11. Work content analyzing apparatus according to claim 1 or 2 , wherein the state information further includes at least any one of movement information indicating whether the worker is moving or not, vital information of the worker, voice information of the worker, ambient sound information of the worker, and ambient image information of the worker.

12. The work content analyzing apparatus according to claim 1 or 2 , wherein the time information stored in the first database is synchronized with clocking means of a system connected with the work content analysis device itself.

13. The work content analyzing apparatus according to claim 1 or 2 , wherein the work content estimated
