Design and Implementation of Multi-Channel ARINC429 Bus

摘要: 为了解决传统ARINC429总线电路设计中采用进口协议芯片带来的占用面积大、不便灵活扩展等问题，提出一种基于国产FPGA的ARINC429总线协议的设计方案，并结合国产驱动芯片，设计了多通道ARINC429的硬件原理图。利用硬件描述语言VerilogHDL进行了发送部分和接收部分的总线协议的设计，并且对其进行了仿真和验证。除FPGA外，外围电路只需要搭配国产总线驱动器，简化了PCB电路的设计，节省了板卡面积，可灵活扩展ARINC429总线通道，有效地提升了数据通信模块的处理能力和集成度。

Abstract: In order to solve the problems of large occupied areas and inconvenient and flexible expansion caused by the use of imported protocol chips in traditional ARINC429 bus circuit design, a design scheme of ARINC429 bus protocol based on domestic FPGA is proposed, and com-bined with domestic driver chips, a multi-Hardware schematic of channel ARINC429. Using hard-ware description language Verilog HDL, the design of the bus protocol of the sending part and the receiving part is carried out, and it is simulated and verified. In addition to FPGA, peripheral cir-cuits only need to be equipped with domestic bus drivers, which simplifies the design of PCB cir-cuits, saves board area, flexibly expands ARINC429 bus channels, and effectively improves the pro-cessing capability and integration of data communication modules.
