新一代军用航空总线系统测试方法研究

摘要

为确保新一代军用航空总线系统——军用1394总线的性能及功能正确性、总线协议符合性及系统应用可靠性,对总线进行系统测试成为必要.搭建总线系统测试平台,从总线电气特性、总线协议符合性、系统应用方面对总线系统测试方法进行研究,经过总线系统的联试、试验及试飞任务,充分表明所描述的系统测试方法有效、可行,为新一代航空系统的飞行安全提供了可靠性保障.%In order to ensure the correctness of the new generation of aviation bus——Military 1394 bus's performance andfunction,and it's protocol conformance and reliability of system application,thesyster test of bus becomes a necessary means.In this paper,it sets up a test platorm for bus system,and researches test methods of this bus system from bus electricalcharacteristics,bus protocol conformance,system application.Through the joint-test,experiments and flight tests of the bus system,it is proved that the system test method described in this paper is effective and feasible,which provides a reliable guarantee for the flight safety of the new generation of aviation system.
