Design of aviation bus protocol interface based on FPGA

According to the key technology of offline test of analogy ARINC429 aviation bus,a novel automation test system based on 8-bit single-chip is designed.

Considering the complexity of both the AFDX protocol and the layout of the aviation bus,simulation can shorten the construction cycle of the network and reduce the investment risk.

The characteristics of the interface control document(ICD) and its function in the avionics bus testing system are analyzed,the shortage of traditional ICD design method is pointed,and the universal ICD design method of avionics buses is described.

Kinds of avionics buses are applied in avionics system presently,but there is still not an integrated,normative and universal method for the buses as well as a strict standard.

The ARINC429, MIL-STD-1553B and CAN avionics bus interface communication system based on Field Programmable Gate Array(FPGA) are designed, which links different bus instruments.

Based on the complex programmable logic device and microprocessor technology,the device is developed to generate multiplex ambipolar serial data which meet the avionics data bus standards for ГОСТ18977-79 and PTM1495-75 of Russia.

A radiation hardened aero-bus transceiver,which can perform high driving capability,low noise and low power supply,is designed based on the analysis of the features of devices in radiation conditions.
