摘　　要：介绍振弦式传感器的基本工作原理、特点和工程中的应用情况,并以其为主要传感器构建监测节点模块,给出一种钢构建筑集散式监测预警系统设计方案和监测软件的设计方法。监测预警系统由中心站、区域子站和监测节点模块三个层次的网络构成,通讯采用RS485串行方式。监测软件在Windows环境下用C#语言开发,给出了软件各个功能模块设计的关键技术。该系统可以对大型钢构建筑的安全状况进行监测评估,在桥梁、涵洞、水利、水电、矿山等领域具有广阔的应用前景。The application in project as well as principle and characteristic of vibrating-wire micro-displacement transducers are introduced, based on the transducers, the monitoring node module is composed, and the design schemes of the distributed monitoring and early warning system of steel construction safety as well as the design scheme of the monitoring software are shown here. The monitoring and early warning system is composed of three level of networks which are centre station, sub-regional station and monitoring node module. The method of communication is RS-485 serial communication. Monitoring software is developed by the language of C# in Windows operating system, the key technique in the function modules of the software are explained in detail. The system can monitor and evaluate the safety of large-scale steel construction, it has a broad application prospects in the field of bridges, culverts, irrigation, hydropower and mining etc.
