【摘要】：针对现有测试系统可扩展性差且无法准确获知伺服机构健康状态的问题,以导弹伺服机构测试系统研制为背景,提出一种基于PXI总线和虚拟仪器的自动化测试方案。从系统总体设计出发,详细阐述测试系统的软、硬件设计,并利用虚拟仪器和PXI总线仪器,搭建了具有高可靠性、便捷性和实用性的伺服机构测试平台,最后提出基于模糊层次分析的数据融合方法,对各项测试指标隶属度进行融合,进而得到伺服机构的健康状态等级。实验结果表明:该系统能够较好地实现各项功能,并具有一定的可移植性和扩展性,能够实现不同伺服机构的测试要求,为装备测试系统开发提供了一定借鉴价值,对长期贮存装备的维护与保养具有十分重要的意义。
[Abstract]:Aiming at the problem that the existing test system has poor expansibility and can not accurately know the health state of servo mechanism, an automatic test scheme based on PXI bus and virtual instrument is proposed based on the development of missile servo mechanism test system.Starting from the overall design of the system, the software and hardware design of the test system is described in detail, and a high reliability, convenience and practicability test platform of servo mechanism is built by using virtual instrument and PXI bus instrument.Finally, a data fusion method based on fuzzy analytic hierarchy process (FAHP) is proposed to fuse the membership degree of each test index, and then get the health status grade of the servo mechanism.The experimental results show that the system can achieve various functions well, and has certain portability and expansibility. It can meet the test requirements of different servo mechanism, and provides a certain reference value for the development of equipment test system.It is of great significance to the maintenance and maintenance of long-term storage equipment.
