Abstract

The present invention discloses a method for monitoring the status of a transmission mechanism, comprising: generating a status monitoring curve using direct position information and indirect position information; identifying the current status of the transmission mechanism based on said status monitoring curve. In the mainembodiment said status monitoring curve is a backlash distibution curve. In addition, the present invention also provides a system for monitoring the status of a transmission mechanism.
