Development Of Virtual Test Equipment Components Aided Generation Software

With the development of computer technology, especially the development of virtual test technology, the design, testing and running of complex system in concepts and methods, has had new leap, being targeted at efficient, optimized, low cost, and low risk, virtual test technology and other advanced methods used in design, test and measuring of system has become the development direction of equipment technology.In connection with virtual test technology status, we propose a new type of virtual testing system architecture and develop corresponding support software platform for large-scale integrated emulation task application. Virtual test system support software platform is a comprehensive test software platform based on component-based design. It introduce component model to realize the package and reference of test equipments. The purpose of this task is to develop the featured test equipment components aided generation software to solve the questions such as great difficult, long cycle of software development, difficult to extend the code test, poor reliability when testing personnel test equipment expansion.Base on the comprehensive analysis of virtual test system architecture and the operation principle and components constructed of supporting software platform, propose the construction method of equipment components object. Abstract the test equipment component function to propose the basic framework of IPO model of the external structure and internal logic of the expression device. For making the interface for Virtual test system software platform support, design the equipment component base class and define a set of fully functional component interface service. Base on the equipment component base class, we propose a more flexible definition method on the external properties and interface component of test equipment. Propose basic control unit that takes Behavioral model of test equipment dynamic link library as development framework, behavior manager mode as device interface behavior. This unit can support the user to extend and customize the device behavior. Develop a standard equipment component object template to achieve a treatment of standard component model. Standard equipment model support GJB289A, RS422, network etc. to achieve fast docking with real equipment. Modeling is according to object-oriented software idea of analysis and development, using UML modeling tool for software requirements, static structure and dynamic behavior. Develop the software using Microsoft Visual Studio.Net 2005 framework which is a development platform for enterprise applications.Software testing both in actual use and laboratory results indicates that the software can satisfy the needs of users, also can support the construction of virtual test system and meet the needs of test tasks operation.
