The technical problem that an existing high-speed serial interface data encoding and decoding method for resisting single event upset and single event transient is large in error correction time or hardware cost is solved. The high-speed serial interface data encoding and decoding method for resisting single event upset and single event transient comprises the steps of encoding and parallel-serialconversion of sent low-speed parallel data by a sending end, and serial-parallel conversion and decoding of received high-speed serial signals by a receiving end. According to the method, the new data formed by splicing the data bits of the multi-beat parallel data are coded respectively, the error data are corrected in the decoding process, the error data can be directly corrected, retransmission is not needed, and the efficiency is high; In the used coding mode, the error correction process is carried out according to columns, even if continuous multi-bit data errors occur, only one error data exists in the error c
