基于虚拟仪器的T/R电源自动测试系统的设计与实现

摘要

介绍了一种基于LabVIEW的T/R电源自动测试系统的设计方法,重点阐述了该测试系统的硬件和软件的设计思想和具体实现.针对T/R电源测试涉及仪表种类多、程控接口多样的特点,系统硬件采用混合总线接口设计以适应测试需求,软件采用层次化、模块化的设计思想,并将时间片轮转和事件触发相结合,流程控制和系统状态监测相结合,对T/R电源的静态和瞬态参数输出特性进行测试.测试流程设计合理,测试效率高效且最大限度保护被测对象,测试结果稳定可靠,满足测试需求.%A design method for T/R power automatic test system based on LabVIEW is introduced,and the design philosophy and concrete realization of the hardware and software are emphasized.In allusion to multi species of instruments and numerous programme control interfaces for T/R power test,the system hardware adopts a design of multi-bus interface to meet test requirement.The software adopts a design philosophy of hierarchicalization and modularization,and combines the time-sharing cycle with event-driven,the flow-control with system state monitor,to test the static and transient parameter output characteristics of T/R power.The test flow designs are reasonable,and the test result is stable and reliable,which can meet the test requirement.
