ARINC429是一种快速、可靠和高效的航空电子设备及其系统之间通信的规范。本文研究了基于Field-Programmable GateArray(FPGA)的ARINC429协议的板卡,该板卡的主要功能就是通过PCI总线来进行2个设备之间的数据通信,通信数据使用ARINC 429协议编码。硬件电路设计主要包括电源复位电路、下载配置电路、PCI电路以及接收和发送电路。系统程序设计主要分为上位机和下位机。经过软件仿真和现场调试后,板卡性能稳定,各项指标和功能均达到了预期的要求。
The ARINC429 is a fast, reliable and efficient specification of avionics and their systems. This paper studies the board of ARINC429 based on Field-Programmable GateArray (FPGA). The main function of this board is to carry on the data communication between two devices through the PCI bus, and the communication data is encoded by ARINC 429 protocol. Hardware circuit design includes power reset circuit, download configuration circuit, PCI circuit and receiving and sending circuit. System programming is mainly divided into upper computer and lower computer. After software simulation and on-site debugging, board performance is stable, the indicators and functions have reached the expected requirements.
