故障信息标准化描述及网络传输方法研究

Research on Implementation Method for Fault Information Standardized Description and Network Transmission

为满足网络故障诊断中跨平台故障信息标准描述和网络传输的需要,基于LabVIEW的跨平台和XML的标准语言描述能力,开展相应的详细设计与实现方法研究,给出典型故障的XML描述方法;通过TCP协议,借助局域网中的客户机/服务器模式来实现故障信息的网络传输;在服务器端,采用VI脚本技术动态创建和运行软件模块,以满足不同故障信息传输和处理的需要;在客户端,供应商和客户模式被用于增强安全性以避免数据丢失;构建的仿真系统验证了设计的可行性,研究成果对今后进一步实现实用的网络化故障诊断系统具有一定的参考价值。

The detailed planning and implementation method are introduced based on LabVIEW for the sake of satisfying the need of cross platform,fault information standard description,and network transmission in networked fault diagnosis.Relevant research was based on the capacities of LabVIEW cross platform and of XML standard description.The XML description method of typical fault information was given.Network transmission of fault information was realized by means of the client/server mode in a LAN through TCP protocol.The technique of VI Scripting was adopted to create and run software module dynamically in the server to meet the need of transmitting and processing different fault information in future.In the client,producer and consumer mode was used to enhance the security to avoid the loss of data.A constructed simulation system verified the feasibility of planning.The research production is useful for implementing practical networked fault diagnosis system further in future.
