【摘要】 目前,自动测试系统在航空、航天、国防、交通、能源等重要领域发挥着关键的支持保障作用。自动测试系统的研究正向着通用化、标准化、网络化和智能化的方向发展。为了减少系统开发中对指定仪器的依赖,减少开发成本,同时弱化测试人员对测试仪器性能的了解,本文结合“虚拟仪器测试软件开发环境”软件开发项目,研究面向信号技术在自动测试系统中的应用。本文首先介绍了自动测试系统的发展现状和发展的各个阶段,介绍了虚拟仪器在自动测试系统中的应用。随后介绍了自动测试系统中的测试泛环境标准集,并在此基础上提出了面向信号的软件体系结构分层,对各个逻辑层次定义了相应的功能和接口。接着给出了相应的实现机制,在分析了完备的信号分类的基础上,使用数据库技术实现真实资源到虚拟资源的映射,并针对自动测试系统在网络化远程方面的应用给出了改进的任务调度算法,通过实例证明,该算法拥有更好的调度效率。本文对虚拟资源管理模块进行了封装,给出了面向信号技术的实现和应用。结果表明,虚拟资源管理模块能够较好的实现仪器的无关性,运行结果体现了面向信号的思想。最后对全文进行了总结,分析并指出进一步的研究方向。更多还原

【Abstract】 Currently, the automatic test system (ATS) plays a key role in the fields of aviation, aerospace, defense, transportation, energy and other important areas. The development of ATS is towards to universal, standardization, networking and intelligent directions. This paper is based on the project of“Virtual Instrument Test Environment”. The application of the ATS based on Signal-Oriented is researched in this paper.First, the development of ATS and virtual instrument in the application of the automatic test system was introduced. Then the standard set of ABBET (A Broad Based Environment for Test) applied in the area of ATS was also introduced. The software architecture based on Signal-Oriented was presented. And the function & interface for every logic layer was also defined.The realization based on the standard signal classifies, with database mapping the real resource and virtual resource was also elaborated in this paper. For the application in parallel heterogeneous Wide Area Network, a priority of the task scheduling algorithm was researched in this article. It was shown that the algorithm has a better scheduling efficiency.Based on the platform of the existing ATS, the resource management module was packaged, and the application of the signal-oriented technology was also proposed. The result indicated that the resource management module could incarnate the Signal-Oriented technology unrelated with instrument.Finally, the paper gives a conclusion of the work and some suggestions for the future research.更多还原
