Based On The General Ats Framework Of The Test System Software Development

With the development of the test technology based on computer, automatic test system becomes larger and more complicated. The traditional software development method is difficult to constitute the automatic test system which accord with the user's requirement in restricted time and budget. The applied software of ATS urgently needs an efficient, comprehensible, extensible and systemic software development method. The development of ATS applied software bases on the open framework is researched in this thesis.Firstly, an introduction of the present situation about ATS and the development method of testing software are given. The research plan of the object-oriented framework about automatic test domain is discussed. Through domain demand analysis, a kind of open ATS architecture is brought forward. The function requirements of ATS are analyzed distinctly by use case model of UML. The main objects about ATS domain are abstracted from physical and logistic entities. After structure and operation of the objects and the relation between them are explained, the meta-model of ATS is formed, which includes the object structure model and the object behavior model.Secondly, the development principium of the object-oriented framework is discussed. The ATS open framework is expatiated roundly in four aspects: hot-spots identification, framework design, framework implementation and framework validation. The basal components of the open framework are detailedly designed in this thesis.Finally, an integrative avionic testing system is developed by reusing the design principium and the architecture of the open ATS framework. In this system, the detailed design of the testing management subsystem, the signal testing, the fault diagnoses subsystem and the data recurrence subsystem is compeleted. The whole application framework is extended by using design patterns. The ATS open framework is validated through developing the integrative avionic testing system. Also, pivotal techniques of this system such as: waveform analysis, multithreading technique, the connection between Labwindows/CVI and database are discussed in this thesis.Project development indicates that the application development method based on the open framework is far more likely to reduce the workload and can guarantee...
