| Abstract: | In this paper, using high-speed and high-performance programmable logic device FPGA, with Nios Ⅱ embedded processor, loading μC/OS-Ⅱ real-time operating system, based on NicheStack TCP/IP protocol stack, using Socket API programming, the design of embedded Gigabit Ethernet in a multi-channel ultrasonic inspection system used in testing Hollow shaft of motor car is described in detail. Testing with Wireshark Network Analyzer installed in the host computer, and the results show that data transmission, receiving and sending data are in exactly the same data, no errors and omissions, the transmission speed is stable with continuous 24-hour transmission test. |
