Research on Real-Time Measurement and Control System for Electrode Length Based on Ultrasonic Sensor

By means of ultrasonic precision proximity sensor, an electrode length real-time measurement and control system, which used industrial control computer as the core and MCGS configuration software as the devebping platform, was developed and designed. The method used to measure the electrode length and to control the pushing speed real-time was presented. The electrode length was calculated by measuring the distance between the electrode terminal and the ultrasonic sensor. With the electrode length as the feedback, a real-time close-loop control system of pushing speed was obtained, and zero speed halt was realized. Industrial operating results proved that this system was reliable and the error was smaller than 10 mm.
