Design of Hardness Sorter Based on Pulsed Eddy Current Non destructive Testing Technology
摘要
Abstract
This paper describes a kind of hardness sorter based on nondestructive testing technology. The field programmable gate array is taken as the central control platform. and the frequeney of DDS signal generator based on FPGA is used to modulate its pulses. At the same time the signal acquisition circuit is designed.The software synchronization sampling technique is used to col ect the feedback status data and then pick up the data related to the hardness of material. At last,the correlativity between the hardness of material and characteristic data is established to distinguish the hardness status.关键词
