摘　　要：当今日益飞速发展的自动化控制技术使得工厂的自动化程度越来越高,然而带来的问题就是一旦检测设备发生故障,会带来控制系统的崩溃,轻则带来经济损失重则造成工业事故。本文就工业故障诊断技术利用OPC(OLE for processing Control)技术设计1种容错控制数据平台来解决这一问题。通过OPC服务获得工业现场数据,利用故障诊断技术对工业数据进行诊断,检测辨识故障传感器,隔离故障传感器,采用已知数据回归法(KnownDataRegression)重构故障数据,作为上层控制软件的输入从而可以使控制系统稳定运行,故障监控软件给操作人员发出检修信号。实验室仿真结果表明该平台可以稳定运行,这为故障诊断和容错技术实际工程应用奠定了基础。Today＇s rapid development of factory automation control technology makes the higher degree of automation, however, once the detection equipment failure, it will bring about the collapse of the control system, and lead to economic losses and even industrial accidents. Fault diagnosis technology, Known Data Regression and OPC technology are integrated to design a fault-tolerant control data platform to address this issue. Industry data obtained through the OPC（OLE for Processing Control） on-site services, and processed by fault diagnosis technology. Sensors＇ faults have been detected by PCA method, and failure sensors isolated. Fault data has been reconstructed by Known Data Regression method, as the input of upper control software, fault monitoring software shows failure to remind operators. The results show that the platform can operate stably, which laid the foundation for engineering applications of fault diagnosis and fault-tolerant technology.
