Position Sensor U sing FixedMagnitute-Pointsfor Guiding Self-Propelled Transportation Machine

摘要

In order to guide a self-propelled transportation machine the guideline and position reasuring system must be used. U sually a fixed guide1ine is used. By this kind of method guide system would be achieved conveniently. But it is difficult and expensive to alter such a fixed guideline when the working route varies. We have investigated a method using ferite magnetic disks as guide points to form the changeable guideline. And a special measuring system has been researched. In this paper we discuss the principle of the method first， then carry out the simulation， and finally analyze the results obtained from both simulation and real system.
