The data transfer interface of the Front End Electronics ( FEE) is designed in for the Water Cherenk-ov Detector Array ( WCDA) in Large High Altitude Air Shower Observatory ( LHAASO) .To meet the require-ment of high-speed data transfer over many front end nodes scattered in a large area, a data transfer interface is specially designed based on the TCP/IP protocol and 1000 M ethernet, which is implemented using the em-bedded system in an FPGA device.Test results in the laboratory indicate that a data transfer rate more than 237 Mbps is achieved, beyond the application requirement.We also conducted 24-hour tests to evaluate the stabil-ity of the data transfer speed, also with good results as expected.
