Working time measurement system and working time measurement method

摘要

PROBLEM TO BE SOLVED: To provide a work time measurement system and a measurement method for improving the accuracy of the measured work time. A work time measurement system 10 measures at least a time determined to correspond between a zone specified by an object identification unit 20 and a work space specified by a worker identification unit 50 as a work time. It is equipped with a working time measurement unit 60. As a result, it is possible to prevent the time in this state from being erroneously measured as the work time when the worker exists in a certain work space but the object does not exist in the corresponding zone.
