Research On Supporting System For Fault Diagnosis And Maintenance Of Missile

As the network communication develops and the weapon tested complicates, the traditional ATS(automatic test system) begins to turn to the direction of distributed architecture and universal frame. Meanwhile, the system with fault diagnosis and maintenance support is drawing more and more attention. The purpose of the task is to develop a new generation of the system for fault diagnosis and maintaince of missile based on virtual test supporting platform.The hardware of the system is based on VXI bus, and several most useful instrument modules are selected. The unit adapter enables different UUT(Unit under Test) is designed. To separate the test mission and test program, the test mission is stored in the database independently; The test flow program supports the jump, end and condition judge operation function, and the fault diagnosis combines the fault variables with their logical relationship; The test mission analysis and every equipment control are capsulated in components, and not only can they combine to construct a project, but also every one of them can run independently; The driver of the instrument module and the function of VISA are imported, which achieves the goal of controlling VXI in MFC; The distributed architecture of the platform is utilized to support network communication, which enable the function of remote fault diagnosis maintenance support. The whole software system is developd successfully under the environment of visual studio 2005.After unit testing and system testing,it has shown that the system has strong versatility and extensibility to achieve the design requirements and performance target put forward by the design book. At the same time, the software is reliable, user-friendly, and could satisfy the need for a new generation of the system for fault diagnosis and maintenance of missile to the user.
