摘　　要：针对目前ARINC429航空总线的研究情况,采用SoPC技术设计多通道ARINC429总线收发装置,解决了目前使用常规芯片导致的系统复杂,使用不便,价格昂贵的缺点。在需要多通道数据收发的场合中,能够有效降低系统的复杂度,提高系统配置的灵活性。另外,在接收过程中研究了改进型倍频容错数据采集方法,首次将其应用于ARINC429航空总线,实验证明该方法能够大大提高数据接收的准确性和可靠性。A muhi-channel aviation bus ARINC429 transmitter-receiver set was designed, in which Sopc technology was adopted to solve the problems such as system complexity, inconvenient application, high cost caused by conven- tional chips used in the current systems. In occasions that require a multi-channel data transceiving, it can effective- ly reduce the complexity of the.system, and improve the flexibility of system configuration. Further, the improved fault-tolerant data acquisition methods were studied in the receiving process, and applied to the ARINC429 aviation bus for the first time. The experiments prove that this method can greatly improve the accuracy and reliability of da- ta reception.
