Abstract

The invention is applicable to the field of communication technology and provides a communication method based on an ARINC 429, a device thereof and an expansion interface. The method comprises a step of receiving a data sending request sent by an X86 system bus, a step of obtaining a data package bit number preset by an ARINC 429 transceiver and packaging the data to be sent to be a data package to be sent according to the data package bit number, a step of obtaining the identification number of the buffer area of the data package, obtaining a buffer area corresponding to identification number from a plurality of preset buffer areas according to the identification number, and storing the data package into the obtained buffer area, and a step of sending the data package into the obtained buffer area to the ARINC 429 transceiver. According to the communication method, the device and the expansion interface, the distinction of the buffer area by the identification number of the buffer area is realized, the isolation of buffer related in a data sending process and buffer related in a data receiving process of the ARINC 429 transceiver is realized at the same time, and the efficiency of data communication and communication reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an ARINC 429-based communication method, device and extended interface. Background technique [0002] Because the ARINC (Aeronautical Radio Incorporated) 429 bus has simple structure, stable performance, strong anti-interference, high reliability, and adopts decentralized control, it is widely used in the aviation field. The X86 system buses commonly used by motherboards using the X86 system include LPC (Low Pin Count), SPI (Serial Peripheral Interface), PCI (Peripheral Component Interconnect), PCIX (PCI-X) and I2C (Inter-Integrated Circuit), etc. The interface directly connected to the ARINC429 bus, therefore, if the computer / device using the X86 system needs to communicate with other peripherals on the ARINC 429 bus, the existing technology has poor scalability, and the direct communication between the X86 system and the ARINC 429 bus cannot be realized . ...
