Vxi Bus Test Software Platform To Connect Technology Research And Implementation,

The Master Dissertation was written with the VXI_BUS Test Software Platform which is a project of tenth five year plan of Equipment Department of National Defense and the task I have accomplished.Brought forward in 80's later and developed fast in 90's ,VXI_BUS is a standard and open instrument bus that is applied to measurement ,control , national defence ,etc. VXI_BUS Test Platform consists of software and hardware parts. The VXI_BUS Test Software Platform is part of software content. It provides a visual programming environment for Automatic Test System (ATS). User can develop ATS conveniently through the software without knowing advanced programming language. This project will supply a gap of VXI_BUS Test Software Platform in China. It's achievement advances application level and ability of research and development for VXI technology .The research of line is belonged to system frame and running mechanism of VXI_BUS Test Software Platform. Being one of two programming element ,the line plays an important role in Software Platform. It shows the connection and control relation of object and is the direct factor which decides the running sequence for objects. The thesis discusses line questions of VXI_BUS Test Software Platform with emphasis . The content as following:Research and realizing of line algorithm. Based on some examples, we study the math-model of line and research the line algorithm. System can get the track of line quickly by using strategies of heuristic search ,depth limited search ,etc.Realizing of line function. According to Object Oriented Programming, the line function class completes the basic function of line.Correlative debugging and testing for line.In addition, the paper discusses briefly the work that makes object perfectly according to what I have done.The result of testing and application indicates that the line algorithm can meet the need of real-time for large application. It is function enough to program. The job will make a great contribution to the application of VXI_BUS Test Software Platform in the future.
