The Design and Develop Of Virtual Experimental Testing Platform
Abstract
This paper presents the simulation of virtual test platform, to achieve the functional of Analog Test Platform, the VC++ visual programming technology and DLL Dynamic Link Library Technology have been used. The concrete realization function includes: Loading the DLL , the right bank of DLL function call , Reading information , painted map devices, imposing signals to the pin, the infliction continuous signal . And Loading DLL is used in the operation of dynamically loaded,DLL library of function calls is used in the base class function to set up virtual interface,then indicators such objects such Lane called the virtual function to achieve the right type of derivative function call to realize the idea. The function of the platform can meet the different needs of the test. The paper also gave a brief description of the significance of the virtual experimental platform, DLL library technology, VC++ Visual Programming Environment and some difficulties in the preparation of a simulation platform, the Loading of DLL Dynamic Link Library and DLL library function derived more difficult to understand, The methods of their realization in this paper has been introduced.
