Design Of Data Acquisition And Analysis Software On Radar Simulation Testing

This subject developed a data acquisition and analysis system software, which is based on component technology. So far, most of data acquisition softwares are suitable for special signal and special testing method, which makes the maintenance and expansion very difficult. The software of data acquisition and analysis on radar simulation testing system in this subject can extend the signal types and the testing methods, and meet the requirement of the users.The software is Based on the Object-Oriented program idea, and component technology. It is designed the modules as components, which have special use, and the software integrates these components to meet the function requirements of the system. This dissertation uses the UML software tool to model the function, static construction and dynamic act of the software.Using Visual C++ development platform and the powerful MFC, this subject develops software which manages and controls components. The software can edit virtual devices and control the actions of the components, so it ensures the diversification application and enhances the generality of the software. Besides, it uses multi-thread technology to realize parallel signals data acquisition, uses ADO(ActiveX Data Objects) technology to access the resource of database, uses COM (Component Object Model) to develop data-acquisition components, data-process components, and so on, uses SQL Server 2000 to design database, since SQL Server 2000 has powerful management functions, and provides plentiful management tools to support integrity, security and operation management of task.The application to be used by the users indicates that this software is not only reliable, but also generality and expansibility. What's more, it reduces the requirements to software user's professional knowledge, and meets the needs of the users.
