基于传感网络的混凝土坝体振动信息检测的布置

在混凝土坝体振动检测的过程中,需要对传感网络节点进行合理布置。但是,在坝体振动信号的传递过程中,对于路由单个传感网络节点的依赖性过大,造成布置过程负载不均匀,检测精确度下降。提出一种基于密度自动调节的传感网络节点布置方法,并应用到了坝体振动检测中。利用得到的坝体节点初始坐标位置。利用振动反馈理论判断坝体上的节点密度情况,根据判断结果调整节点的最优位置。实验结果表明,利用该方法进行大型坝体振动检测,能够提高检测的振动时间,提高了检测的效率。

Based on sensor network layout of concrete dam body vibration information detection

In the process of concrete dam body vibration testing, need reasonable decorate on sensor nodes. However, in the process of dam body vibration signal transfer, for routing the dependence of the single sensor network node is too big, cause uneven load arrangement process, detection accuracy. Put forward a kind of sensor network node layout method based on density automatic adjustment, and apply to the dam vibration tests. Using the node initial coordinates of arch dam. Using the theory of vibration feedback judge the node density on the dam body, adjust the optimal position of the node according to the judgment. The experimental results show that the large dam vibration tests using this method, can improve the detection of vibration time, improve the efficiency of detection.
