| Abstract: | A four channel ultrasonic flaw detection module based on ARM and FPGA is introduced in this paper,giving its whole structure scheme,illustrating hardware design ideas and hardware expansion of multi-channel ultrasonic flaw detection device with the 4 channel ultrasound analog signals as a group.These are discussed including high speed LVDS data collection,signal processing,timing synchronization function in FPGA,bus interface between ARM and FPGA,function in ARM embedded system and the network communication.The practical application shows that the function module can reach the design requirement,and can realize hardware expansion easily. |
