综合化飞机环境监视系统研究及其数字仿真测试

 综合模块化航空电子(IMA)技术日益成为飞机航电系统开发的主流构型。基于美国航空无线电技术委员会(RTCA)对飞机环境监视系统(AESS)的定义,分析了AESS的发展过程及技术趋势,以空客A380、Boeing787飞机的AESS为例进行现状分析,依据ARINC768规范开展了综合飞机环境监视系统(IAESS)方案及架构设计,实现了由综合飞机环境监视系统处理单元(IAESSPU)对T3CAS(TCAS、TAWS和ATCRBS)和WXR数据综合与处理的统一,开展了基于高级体系结构(HLA)的IAESS数字仿真系统设计、测试用例和性能分析,验证了IAESS具有高可靠性、低功耗、低总量等优点,未来IAESS发展也将进一步使得系统具备多功能特点。

Study on Integrated Aircraft Environment Surveillance System and Its Digital Simulation Test

Integrated modular avionics (IMA) technology is becoming the main trend of modern avionics. Based on the definition of Radio Technical Commission for Aeronautics (RTCA), this paper introduces the development process and technology tendency of aircraft environment surveillance system (AESS). With Airbus A380, Boeing787 AESS as examples, it also analyzes the status quo for AESS. According to ARINC768 standards, the prototype and framework of ａ so-called integrated aircraft environment surveillance system (IAESS) is designed, which realizes the data synthesis and the information processing consistency for T3CAS (TCAS, TAWS and ATCRBS) and WXR by the integrated aircraft environment surveiuance system processing unit (IAESSPU). Then a digital simulation for the IAESS is performed based on high level architecture (HLA). The test examples and simulation performance are analyzed too. The results verify the high reliability, low power consumption and low volume of the IAESS. Future development of IAESS is also discussed.
