This article describes the use of single-board machine control on-line detection system to measure the geometry of the fuse part of the probe and intelligent research on the sensor, as well as to achieve the function of the detection system to establish mathematical processing methods, such as the size of the ultra- , Sensor output characteristics of the computer linearization, peak discrimination and if necessary, follow-up characteristics of the mechanical measuring device analysis. The detection system can measure the actual value of measured geometry online, calculate the average, standard deviation, adjust the amount of knife, and display or print out data processing results, and has self-diagnosis, alarm and other functions. The detection system is the displacement obtained by the measuring head to the eddy current sensor is converted into electricity, and then through the thirteen A / D conversion board into digital, and after the single board machine analysis and display or print the results. Through the laboratory simulation test, the repeatability of the detection system is better than 0.065%, indicating the stability is better than 0.020%.
