为实现对盾构各系统集中监视、控制、数据存储、故障报警、界面多语言切换等功能，采用NET框架下C#自主开发的方式，开发出盾构上位机监控系统。首先简要介绍系统的开发环境和运行的软硬件环境，然后按软件部分系统逻辑分层顺序，分别从以下3个方面进行详细描述： 1）底层负责与PLC通讯的OPC协议； 2）自定义控件、组合显示界面、报警界面，曲线图界面及注浆界面的多语言切换； 3）数据存储格式、海量数据的形象化统计分析。主要研究结论如下： 1）系统经过中铁号百余台盾构的实际应用证明设计符合盾构监控要求，界面友好、稳定可靠； 2）系统虽为盾构量身定做，但其人机界面软件部分包含了组态软件的大部分功能，进行功能扩展后可以移植到其他工业控制系统。

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.
