The Study Of The Monitor Method To Tension Difference Of Multi-rope Friction Hoister Based On CCD Technology

This paper synthesizes the research result of monitoring multi-rope tension of friction winder at homeland and abroad, and studies a new monitor method on the difference of tension among cables based on CCD technology. Firstly, this paper analyzes the transformation rule between the tension difference among cables and the difference of stretch deformation due to it in detail, and establishes the more exact mathematic model describing their relation. Then the tension difference among cables can be measured by detecting the altitudinal difference among the signs on cables. This paper studies the possibilities of measuring the altitudinal difference among the signs on cables using CCD technology, and detecting the difference of tension among cables. It also develops the main software and hardware for the whole detecting system based on CCD technology. Finally, the detecting system which is developed is analyzed in the lab. The result indicates that this system using in the difference of tension detection is feasible, and has lots of merits such as contactless on-line and real-time measurement.
