Design of Automatic Control System for NDT Device

The article designed a kind of new nondestructive testing device control system to increase the test efficiency and improve the reliability of computed tomography. This system could not only precisely locate and control the turntable and lifting platform by adopting digital control, servo control and other advanced control methods, but also develop a high-precision servo turntable by using a three-layers closed-loop controller. This system, whose workpiece rotate platform is particularly suitable for small-space detection, has an increasingly improved automatic detection efficiency of 20 work-pieces at a time and a wider detection scope of maximum height of up to 50cm. By the means of pre-setting parameters, high-precision servo turntable can rotate to any regulated angle, offering a satisfactory platform for computed tomography. The system, as a new type of automatic non-destructive testing platform, adapts to the digital transformation of traditional X-ray detection device as well.
