基于PXI总线的遥测数字量变换器测试台的研制

摘要

根据数字量变换器的功能和特点,制定了基于PXI总线的数字量变换器测试台的设计方案,并对其工作原理进行了阐述.根据设计方案,对测试台硬件进行了设计,并编制了专用的测试软件.该测试台采用了先进的PXI总线结构,整套系统通用性强、可靠性高.目前,该测试台已经完成与数字量变换器的联调,并交付靶场使用.实践证明测试台设计满足使用要求.%According to the functions and characteristics of the digital-converter, the solution of the digital-converter test system is developed based on PXI-bus, and working principle is explained. Then the hardware of test system is designed, and a special test software is compiled. The advanced PXI-bus configuration is adopted, so it has the advantages of interchangeability and reliability. Debugging between test system and digital-converter is completed, and the test system has been delivered to range. Practice proves that the test system is satisfied with the using request.
