摘　　要：将新型树状结构的无线传感器网络应用于桥梁健康监测,保留了有线网络监控的优点,弥补了其布线复杂问题的不足.桥梁建筑在使用运行时,由于材料性能随着时间推移而老化,从而导致桥梁结构安全性能下降.基于新型树状结构的无线传感器网络利用业务方向性特点,有效减少资源浪费,提高通信效率.通过数据采集,传送或接收及网络数据分析,建立了基于新型树状结构的桥梁监测系统,提高了系统的能效和生命周期,并在系统鲁莽性和数据传输效率方面得到了提高.Wireless sensor network with new tree structure applied in bridge health monitoring keeps the advantages of wired network monitoring and covers the shortage of complex wiring. With the material performance aging over time, the safety performance of the bridge structure will decrease. Due to the feature of service direction,the waste of resources can be reduced and the communication efficiency can be improved. Through data collection,transmission and receiving and data analysis, bridge monitoring sys- tem based on novel tree structure is established, which improves the system energy efficiency and life cy- cle and also increases the system crudeness and data transmission efficiency.
