摘　　要：为提高技术保障的效率,以PXI测试仪器为硬件平台,设计基于故障树的推理软件平台。通过对测试点的测试数据进行采集,再进行故障的合理识别、推理和判断,推断出正确的结果,将故障定位在板级(即最小可更换单元)。结果表明,该系统自动化程度高、操作方便,能实现对电台故障"板级定位"的模块化、快速化和自动化测试。In order to improve the technology maintenance efficiency,the radio fault diagnosing system uses a PXI test unit as the hardware platform.Design reasoning software platform based on the fault tree.Then carry out fault rational reorganization,reasoning,and judgment,deduce the correct result,and locate fault in board-level（that is the minimum alterable unit）.The result shows that the system is high automation degree and easy to operation,which can realize module,fast and automatic testing for radio station fault ＂board-level location＂.
