SELF CALIBRATED BENDING RADIUS MEASUREMENT SYSTEM FOR UNDERGROUND PIPE LINE OF ELECTRIC POWER AND BENDING RADIUS MEASUREMENT METHOD USING THE SAME

摘要

The present invention relates to a system for measuring a radius of curvature for an underground wiring pipe having a self calibration function. The present invention comprises: a first pipe diameter measurement means measuring an inner diameter of an underground pipe; a second pipe diameter measurement means measuring the inner diameter of the underground pipe and having a length different from the length of the first pipe diameter measurement means; a communication means transmitting the measured diameter of the pipe to a central processing unit; and the central processing unit calculating the actual diameter (D) of the underground pipe and calculating a radius of curvature of the underground pipe. According to the present invention, the system is capable of constructing more accurate data with respect to the underground wiring pipe and further improving a construction quality of the underground wiring pipe.
