摘要
为了对结构工程进行长期健康监测,并可根据监测数据进行分析、评估结构安全性,设计了一套实用性较强的无线监测系统。该系统采用由微功耗的单片机控制的24位模数转换器完成模数转换,加入太阳能充电方式来保证节点可以长时间工作。数据通过针对实际应用定制的网络协议进行传输,用户可以根据不同应用场合选择现场或者远程监控模式,上位机软件实时显示监控状态并给出可视化图形分析结果。测试实验证明,该系统具有工作时间长、低功耗、易维护和搭建和移动方便等优点。
A wireless monitoring system is designed for long-term structural health monitoring（SHM）in civil engineering in this paper.In this monitoring system,one microprocessor with low power dissipation is used to process the data received from the 24-bit analog-to-digital converter.The system enhances energy performance by using solar technology.Data can be transmitted using customized network protocol and user can choose on-site or remote monitoring mode according to different needs.And the program of host computer has a view interface to display all the results and messages.Experimental result proves that the system has the advantages such as long work time,low power dissipation and the flexibility of deployment and movement.
