| Abstract: | Eddy current detection technology futures high accuracy and pollution-free and is applicable to the detection of metal micro-crack.This paper designs a eddy current detection system.It can sample at high speed and display continuously.When micro-cracks on the metal are detected it will alarm with sound and light.It is based on the high-speed interface of the processor ADSP-BF531,uses high speed ADC to sample data.And it can display the results clearly and continuously with the synchronization dynamic random access memory(SDRAM) and TFT-LCD.The system has simple structure,fast sampling speed,and small volume.So it has a wide practical application value. |
