基于卫星定位的一类位移监测系统的设计与实现
|
摘要
在卫星定位技术以及无线传感器网络技术的基础上设计了一种位移监测系统。当节点所在位置发生移动时,系统能够及时发现并向用户发出警报。系统包括硬件和软件两个方面。其中,硬件方面负责采集卫星定位数据并通过无线方式将其发送至上位机。软件方面则用来对数据进行分析和处理。为了提高系统精度,设计了一种基于滑动均值滤波和一阶前向差分的位移报警算法,并通过大量现场实验数据得出了合理的阈值,使该算法的精度达到了期望要求。
A displacement monitoring system based on satellite positioning and wireless sensor network is designed in this paper.When the node moves,the system can promptly detect the displacement of the node,and be able to alert users in time.The displacement monitoring system includes two aspects:the hardware part and the software part.The hardware part is responsible for collecting satellite positioning information and transmitting it to the control center.Displacement monitoring software is used to summarize and analyze the data.In order to improve accuracy of the system,a warning algorithm based on sliding mean filtering and first order forward difference is proposed.The most reasonable threshold is obtained by field experiment,which makes the algorithm more effective.
