基于虚拟仪器的智能远程诊断系统的研究

Foundation into the Remote Instrument Fault Diagnosis Based on Virtual Instrument

对虚拟仪器和远程诊断技术作了简要的分析,提出了一种基于虚拟技术的智能远程诊断系统模型,并提出了如何构建系统模型.模型采用三级网络结构:设备现场故障监控系统;车间或企业局域网故障监控中心;远程监控中心.对每级的任务进行了分析和规划,每级通过Intranet或Internet实现网络间的相互通讯,实现设备的智能远程故障诊断.

In this paper, we analyze the virtual instrument and the remote fault diagnosis, put forward a system model of a remote intelligent fault diagnosis system based on virtual instrument, and discuss how to build the system model. The system is divided into three parts: the field equipment fault monitoring system, the workshop or enterprise local fault monitoring center and the remote monitoring center. Then we assign and analyze its functions. The long-distance fault diagnosis is realized by the communication via Intranet and Internet.
