In order to solve the questions such as high requirement for inspection personnel, low detection efficiency, easy to leak detection and false detection for the ultrasonic detection to large object's defects, a multi-channel automatic ultrasonic testing system was designed. FPGA and ARM were used as core chip to design its hardware circuit,VHDL language was used to write the software of FPGA, C language was used to write the software of ARM. UDP/IP protocol was used to write the Ethernet communication software between the multi-channel automatic ultrasonic testing system and the upper computer, the upper computer software is designed by Lab VIEW. The results of experiment show that this system can realize functions such as the automatic ultrasonic testing for defects of large object, real time display of C scan imaging and defects locating. This system has many advantages such as high precision, high detection efficiency and operating convenience.
