基于模拟ARINC429总线自动测试的系统设计与实现

System design and implementation of automatic test based on the ARINC 429 bus

在TDC-1综合信号装置自动测试系统中,针对模拟ARINCA29航空总线进行脱机检测这一关键技术,设计了基于8位单片机的新型自动测试子系统。设计中严格遵循ARINCA29规范,采用429专有芯片HS3282和HS3182完成模拟信号收发工作,单片机完成部分信号控制与处理,虚拟仪器完成软件开发。该系统为ARINC429输入信号的产生提供了简单实用的方法,在航电系统中具有典型性和实用性。

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. ARINC429 Protocol Tutorial is Strictly executed and Special CMOS chip HS3282/HS3182 of ARINC429 are adopted to accomplish analogy signal transmission, part of signal is controlled and managed by single-chip, software is developed by VI. It is a simple and utility method of simulation ARINC429 Bus for portable and offline test system,which is of typicalness and practicability in avionics system.
