problem in the development of modern monitoring system. The successful application of Industrial Control Software (ICS) provides a good idea for the development of network-based Online Monitoring and Diagnosis System (OMDS). Although the ICS emphasize on control function while the OMDS put more attention on the data acquisition, signal analysis and save of long-running data, the “configurable” approach during the development of ICS can make the OMDS well adapt to various machinery and become “flexible”. Additionally, the OMDS become more smarted by integrating the information fusion methods and neutral network with normal frequency-spectrum analysis methods, and enhance the capability of fault diagnosis and safety assessment for rotating machinery [7].
因此，有效地和可靠地开发系统已成为现代监测系统发展的关键问题。工业控制软件（ICS)的成功应用为基于网络在线监测和故障诊断系统（OMDS)提供了一个好的思想。尽管工业控制软件强调控制功能而在线监测和故障诊断系统专注于数据采集，信号分析和长期数据的保存，在工业控制软件的发展过程中“结构配置”的方法能使得在线监测和故障诊断系统很好的适应各种机械装置和成为“柔性化”。此外，在线监测和故障诊断系统通过集成的信息融合法和带有正常频谱的神经网络分析法而变得更加智能，它提高了故障诊断和旋转机械的安全评估能力。
