GPWS ( Ground Proximity Warning System(GPWS) ) is an important aviation electrical equipment which is used to ensure flight safety, its faults have great impact on the flight safety. GPWS(近地警告系统(GPWS))作为保证航空器飞行安全的重要电子设备,其产生的故障对飞行的影响是十分巨大的。
The Ground Proximity Warning Computer System is a kind of electronics warning equipments, which is widely installed in various transporter currently. It receives the data, which is sent out by inertia! 近地告警计算机(GroundProximityWarningComputer,GPWC)系统是目前各种运输机上普遍安装的一种电子告警设备。
This paper analyses the principle and structure of ground proximity warning computer. Based on it, the test system structure, the software algorithm and the key problem are particularly narrated. 在分析告警计算机工作原理和组成结构的基础上,详细叙述了近地告警计算机自动测试系统的软硬件设计,重点分析了设计中的难点问题。
