Abstract

The invention belongs to the technical field of data transmission and particularly relates to an avionics target hardware equipment Ethernet data loading method. A data loading module, a FIND processing module, a TFTP protocol module, an ARINC665-3 protocol file processing module, a log module and a state reporting module are used for achieving the avionics target hardware equipment Ethernet data loading method. Compared with the prior art, the avionics target hardware equipment Ethernet data loading method can meet the file transmission requirements of different Ethernet environments of avionics, effective file transmission under the avionics Ethernet environment is achieved, data transmission operation can be controlled according to the specific operation situation of target equipment, flexibility is high, received loading file format and integrity can be checked, and accordingly the safety of needed data is high.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to an Ethernet data loading method of an avionics target hardware device. Background technique [0002] Ordinary TFTP (Trivial File Transfer Protocol, simple file transfer protocol) is a protocol in the TCP / IP protocol family for simple file transfer between the client and the server, providing uncomplicated and low-cost file transfer services . It is implemented based on the UDP protocol. This protocol is designed to transfer small files, so files can only be obtained or written from the file server, and directories cannot be listed, and authentication is not performed. TFTP format such as figure 1 shown. Opcode: operation code, RRQ is 1, WRQ is 2, DATA is 3, ACK is 4, ERROR is 5; file name: the file name is a NETASCII code character and ends with 0; Mode: this interface is fixed as "octet"; block Number: start encoding with 1, add 1 for each data block, ...
