Printing method for achieving ARINC 744A-1 standard based on Ethernet and printing conversion device

Abstract

The invention provides a printing method for achieving the ARINC 744A-1 standard based on the Ethernet. The printing method includes the steps that a printing file sent by an avionic system is received through a 429 bus; the printing file is converted into a file format which can be recognized by a printer; the converted printing file is sent to the printer. The invention further provides a printing conversion device. According to the printing method for achieving the ARINC 744A-1 standard based on the Ethernet and the printing conversion device, the printing file of the avionic system based on the 429 bus can be converted into data with an Ethernet format, and then the printing file is printed by the Ethernet printer.

Description

technical field [0001] The invention relates to a printing method and a device, in particular to a printing method and a printing conversion device for completing the ARINC744A-1 specification based on the Ethernet. Background technique [0002] At present, the printing technology of the avionics system on the aircraft is either directly connected to the printer in the cockpit or the cabin based on the 429 bus, or directly connected to the printer in the cockpit or the cabin based on Ethernet, so as to realize it through the driver or the corresponding printing standard. Printing tasks of text or graphics. [0003] Aviation printers include Ethernet printers that follow the 429 bus protocol and the LPD / LPR protocol. In an aircraft using the 429 bus avionics system, if a printer that follows the 429 bus protocol is used to connect to the avionics system, two An independent 429 bus is used for data transmission. If two independent 429 buses are used to connect the avionics sy...

[0003] Aviation printers include Ethernet printers that follow the 429 bus protocol and the LPD / LPR protocol. In an aircraft using the 429 bus avionics system, if a printer that follows the 429 bus protocol is used to connect to the avionics system, two An independent 429 bus is used for data transmission. If two independent 429 buses are used to connect the avionics system and the printer, the weight of the aircraft will be further increased; if an Ethernet printer following the LPD / LPR protocol is used, although it is not necessary Adding an independent 429 bus to connect with the avionics system, but, because the 429 format data words transmitted by the 429 bus cannot comply with the existing data transmission protocol for printing, there is an urgent need for a method that can convert the data in the 429 format into compliance with A data method that can be recognized by the printer of the LPD / LPR protocol requires a method that can reduce the weight of the aircraft and also enable the avionics system using the 429 bus to connect to the printer that follows the LPD / LPR protocol, and complete ARINC744A-1 based on Ethernet standardized method
