针对自行火炮随动系统检测维修设备较为匮乏的现状,以具有PCI总线的工控机为平台,采用研华数据采集卡、I/O控制卡、RS - 232串口并辅以相关传感器及信号调理电路,构建了自行火炮随动系统测控系统硬件结构；通过分析目前较成熟的故障诊断专家系统的特点及随动系统故障特性,设计和实现了基于案例推理的故障诊断专家系统；最后介绍了基于VB和DLL技术下的系统软件的开发；使用表明,测控系统有效地提高了装备维修保障能力.%Aimed at the present condition that test and maintenance equipment of self—propelled artillery servo system is short of, using industrial controlling computer as platform which has PCI bus, Advantech data acquisition card, control card for I/O、 RS —232 COM port and assisting with related sensor and signal adjust circuit, the hardware structure of a test and control system of self —propelled artillery servo system is constructed. By analysising current developing fault diagnosis expert systems' feature and servo system's fault characteristic, fault diagnosis system based on Case—based reasoning is designed and realized. Finally software develpment based on VB and DLL techniques is introduced. It is proved that the system effectively improves the ability of equipment maintenance.
