R & D of Electric Control System for Steel Pipe Head-tail Aligning Operation of Ultrasonic Detection Line

Elaborated in the essay are the main aspects concerning an home-made electric control system for steel pipe head-tail aligning operation of the ultrasonic detection line，including the work principle，the theoretic basis， the calculation process and the configuration of the hardware， etc.This electric control system gets the dynamic distance issue into a time-related one，and employs the PLC computation and timing functions to perform accurate tracking of non-hitting pipe aligning operation as required by the detector proper.The 5-year long operation history of the said electric control system has shown its operational consistency，safety and reliability，and high profitability，being absolutely worth substituting relevant similar imported equipment.
