基于无线传感器网络构建了桥梁健康监测网络系统,为了实时检测和获取桥梁状态信息,研究了无线传感器网络桥梁健康监测系统中传感器节点间数据传输的时间同步问题。同时通过时钟同步算法仿真,验证了自适应式时间同步算法在无线传感器桥梁健康监测系统中的有效性与可靠性。仿真结果表明,非对称式自适应时钟同步算法能够较好地实现时钟同步并对桥梁的健康状况进行实时监测。
Based on the wireless sensor network, a bridge health monitoring network system is constructed. In order to detect and obtain the bridge status information in real time, the time synchronization of data transmission between sensor nodes in the wireless sensor network bridge health monitoring system is studied. At the same time, through the simulation of clock synchronization algorithm, the validity and reliability of adaptive time synchronization algorithm in wireless sensor bridge health monitoring system are verified. The simulation results show that the asymmetric adaptive clock synchronization algorithm can achieve the clock synchronization well and monitor the bridge health in real time.
