POSITION TRACKING DEVICE IN TUBES USING SONIC WAVE AND POSITION TRACKING METHOD USING THE SAME DEVICE

摘要

The objective of the present invention is to provide an apparatus for detecting a position of a transfer body in a tube using a sonic wave capable of grasping the position of the transfer body which is moved by pneumatic pressure, and a method for tracking the position using the same. The apparatus for detecting the position of the transfer body by the present invention to achieve the objective includes a position tracking unit which is configured to detect the position of the transfer body in a movement route moving or existing through the inside thereof. The position tracking unit includes a position tracker which discharges the sonic wave as to a medium in the movement route where the transfer body moves, and measures the position of the transfer body by detecting a reflected wave reflected from the transfer body.
