【摘要】：测控装备多布设于高山海岛,传统排除故障的手段多是人员乘车前往或者电话咨询,由于天气原因,车辆原因,人员不在现场不能可视化的看到故障现象等因素,往往会影响排除故障的及时性和准确性;随着雷测,光测,遥测等测控装备不断向高集成化,高自动化发展的特点,都迫切需要我们设计和实现一套测控装备远程故障诊断系统。本文从测控装备故障诊断的实际需求出发,以故障树,故障字典诊断技术为理论背景,NI公司的虚拟仪器硬件和虚拟仪器测试技术[1-2]为基础,设计并实现了测控装备远程故障诊断系统[3-5]。论文首先从实际装备的战术指标分析,研究了装备故障的特性及测试部分,选取了虚拟仪器硬件系统;根据故障诊断系统的功能特点设计了测控装备远程故障诊断系统的总体结构。其次,对系统所用到的理论和关键技术进行深入的研究,设计了系统的自动检测故障树模型,手动检测故障树模型,详细阐述了故障字典原理,采用故障树与故障字典相结合的方式,构建了测控装备远程故障诊断系统,并将该方法整合到软件的实现中。最后,设计了测控装备远程故障诊断系统的中心端软件和装备端软件,基于虚拟仪器体系结构,选取了适应测控装备测试的硬件部件,利用Labview和SQLServr2005实现了测控装备远程故障诊断系统。系统在实际应用中验证了正确性,可靠性和有效性。
[Abstract]:Most of the measuring and control equipment is arranged in the alpine islands. The traditional means of troubleshooting are mostly personnel travelling by car or telephone consultation, due to weather reasons, vehicle reasons, and the fact that the personnel are not able to visualize the failure phenomenon at the scene, and so on. It often affects the timeliness and accuracy of troubleshooting. With the development of lightning, optical and telemetry, etc., the equipment is becoming more and more integrated and automatic. It is urgent for us to design and implement a remote fault diagnosis system for measuring and controlling equipment. In this paper, based on the theory background of fault tree and fault dictionary diagnosis technology, the virtual instrument hardware and virtual instrument testing technology [1-2] of NI Company are considered as the basis of the actual requirement of fault diagnosis of measuring and controlling equipment. The remote fault diagnosis system of measuring and controlling equipment [3-5] is designed and implemented. Firstly, from the analysis of the tactical index of the actual equipment, the characteristics of the equipment fault and the test part are studied, and the hardware system of virtual instrument is selected. According to the functional characteristics of fault diagnosis system, the overall structure of remote fault diagnosis system for measuring and controlling equipment is designed. Secondly, the theory and key technologies used in the system are deeply studied, and the automatic fault tree model and manual fault tree model are designed, and the principle of fault dictionary is described in detail. The remote fault diagnosis system of measuring and controlling equipment is constructed by combining fault tree and fault dictionary, and the method is integrated into the realization of software. Finally, the central software and equipment software of remote fault diagnosis system of TT & C equipment are designed. Based on the architecture of virtual instrument, the hardware components adapted to the testing of TT & C equipment are selected. The remote fault diagnosis system of measuring and controlling equipment is realized by LabVIEW and SQLServr2005. The system is proved to be correct, reliable and effective in practical application.
