Design And Study Of Software Architecture For AMU Test System Based On PXI-bus

The object of this thesis is software structure model of Automated Test Equipment(ATE)which is designed for Audio Management Unit(AMU). On basis of study and research of Component Maintenance Manual(CMM) of AMU, the top level software structure and realization of ATE that are satisfied by test steps and communication protocols which are specified by CMM are profoundly discussed.First of all, the background of project for AMU automated test equipment based on PXIbus is briefly introduced. Then, by the contrast of features of the different buses, advantage of apply the PXI-bus into the project is demonstrated. Furthermore, through deeply analyzing architecture of PXI-bus hardware platform, as well as study the correlativity of test tasks that are specified in CMM and all kinds of parallel test algorithms adaption to the project, Quantum Genetic Algorithm(QGA) is selected as scheduler algorithm. By consulting the modern Virtual Instrument design pattern, ACP simulator is designed to satisfy the protocol between ACP and REU. The upper software is constructed through TestStand4.0, and the bottom functional implementation is completed by VC++. Multi-thread and Oriented Object Programming design thought is merged into the whole software to enhance the reusability and parallelism. Finally, partial items tests of test software according to CMM are executed which indicates the high efficiency of software system.
