摘　　要：运用TinyOS软件对无线传感器编程,使节点构成无线传感器网络,并将其应用于大型土木结构的健康监测。首先介绍了无线传感器网络的特征和TinyOS操作系统,然后叙述了采用Micaz构成的无线传感器网络进行悬臂梁模态频率测试的过程,最后讨论了程序编写和试验方法的有关问题,并将试验结果与有线传感器及有限元分析结果进行了比较。结果表明,该试验方法是有效可行的。Programming wireless sensor using TinyOS software to form wireless sensor networks was applied to large-scale civil structural health monitoring. Firstly, the characteristics of the wireless sensor networks and TinyOS operation system were introduced. Then, the whole process of the modal frequency test of a cantilever beam using Micaz smart sensor was depicted. Finally, some relative problems of programming and experimental method were discussed, and the experiment result was compared with wired sensor and finite element analysis. The results show that the experimental method is feasible and effective.
