Abstract:

A kind of shield monitoring system is developed on basis of C# selfdeveloping mode under .NET framework, so as to realize the centralized monitoring, control, data storage, fault alarm, and multilanguage interchange of each system of shield machine. In this article, the developing environment and the operating software and hardware environment of the monitoring system is presented briefly; then the monitoring system is discussed in respect of the OPC agreement between the bottom level and PLC, the multilanguage interchange of the selfdefined control, composite page, alarming page, curve page and grouting page, and data storage mode and visualized statistical analysis of the mass data. Conclusions drawn are as follows: 1) It is demonstrated that the monitoring system developed is interfacefriendly, stable and reliable and can meet the requirements of the shield machines; 2) The Supervisory Control and Data Acquisition (Scada) used in the HumanMachine Interface (HMI) of the monitoring system of shield machines can be used in other industrial control systems after function developing.
