【摘要】 综合测试技术是计算机技术、总线技术、虚拟仪器技术以及数据库技术的集成化前沿技术。本文基于测试系统小型化、硬件化、通用化以及标准化,设计了符合某型号飞行器在真实环境下飞行中被控参量的检测、分析和保存。具体研究内容包括以下几个部分:根据某飞行器综合测试需求,提出了基于MFC和虚拟仪器的软件设计方案,并对其关键技术进行了研究;以PXI总线仪器为核心,以信息采集为主线,将PXI总线自动测试技术、面向对象的程序设计技术相结合,应用于某飞行器综合测试系统的相关研发;各个模块化功能的设计,其中包括人机交互界面、数据采集模块、设备自检模块、测试流程解释模块和数据存储模块等以及设计相应的数据库结构。此外,在测试流程中应用多线程访问的方法对仪器资源进行获取,有效防止死锁现象,而且利用前后台程序实时显示脉冲信号以及关键模拟信号。利用系统能够在测试过程中对数据进行采集与存储,同时,在后续应用中可以对存储数据进行查看和进一步的解析。经过与被测对象模拟装置进行仿真联调以及对现场调试后,结果均表明本次设计的测试系统具有良好的人机交互界面,稳定,易于操作,精确等特点,满足系统设计的要求。
【Abstract】 Comprehensive testing technology is the integration frontier technology of computer technology,bus technology,virtual instrument technology and database technology.Based on the miniaturization,hardware,generalization and standardization of the test system,this paper designs the detection,analysis and preservation of the controlled parameters of a certain type of aircraft in real flight environment.Specific research contents include the following parts: According to the requirement of integrated test of an aircraft,a software design scheme based on MFC and virtual instrument is proposed,and its key technologies are studied;With PXI bus instrument as the core and information acquisition as the main line,PXI bus automatic test technology and object-oriented programming technology are combined to be applied to the research and development of an aircraft integrated test system;The design of functional modules,including man-machine interface,data acquisition module,device self-test module,test flow interpretation module and data storage module,and the design of the corresponding database structure.In addition,multi-threaded access method is applied to acquire instrument resources in the test process,which can effectively prevent deadlock.The front and back-end programs are used to display pulse signals and key analog signals in real time.The system can collect and store data in the testing process.At the same time,the stored data can be viewed and further analyzed in subsequent applications.
