某型机载综合显示系统自动测试仪的设计

空情信息感知能力是决定飞机战斗力强弱的主要因素之一;机载综合显示系统能将大量、复杂、融合的空情信息,直观地显示给飞行员,为其完成飞行训练及作战任务提供首要的决策依据;此机载综合显示系统自动测试仪是一个基于计算机的智能化的测控系统,可以实现对机载综合显示系统工作状态的高效测试和故障诊断;首先介绍了基于PC的自动测试仪的设计思想,重点分析了测试仪的硬件及软件的实现方法;此外在软件部分提出了一种利用Windows API简化编程实现串口通信的新方法;系统总体设计先进、精度和自动化程度高、通用性好,完全满足测试及诊断的需要,可方便地推广应用到新型机载综合显示系统上。

Design of Automatic Test Equipment for Airborne Integrated Display System

The sensibility of flight information is one of major factors that determines the force of fighter.A mass of complex and blended flight information can be displayed by Airborne Integrated Display System to pilot,and it is the ehief condition of flight training and fight. This Automatic Test Equipment is the intelligent computer measurement and control system,can realize a effective test of the working state of Airborne Integrated Display System and failure diagnosis.The design idea of Automatic Test Equipment on PC is introduced firstly,and the realization technique of hardware and software is diseussed chiefly.Noticeably,the new way of realizing serial interface communicating based on Windows API simplified program is described in software.The system is advanced with high performance of accuracy and automa- tion and good at currency,it can fully meet the demand of test and diagnosis and can be applied to new style of Airborne Integrated Display System.
