基于无线传感器网络的多点位物体流量监测系统的应用

Application of multi-point flow monitoring based on WSNs

针对目前对物体流量信息采集所存在的多点位同时监测和被检物体的区别化识别两大问题,设计了一种基于无线传感器网络的物体流量监测系统。该系统由监测节点、基站节点及上位机组成,监测节点之间构成链状拓扑结构,将监测到的数据汇总到基站节点,再由基站节点与上位机相连,将数据传到上位机进行流量统计与数据分析。系统中所涉及的监测过程无需外设辅助标签,同时实现对多点位物体的流量监测,并解决识别物体种类的问题。

Aiming at two major problems in object flow information collection that multi-point monitoring and object type distinguishing can＇ t be realized, a system for object flow information monitoring based on WSNs is designed. The system is composed of the monitoring nodes, the base station node and the upper. The monitoring nodes send the monitored data to the base station node through a chain topology structure. Then the data are sent to the upper computer for statistics and data analysis. This system can realize multi-point object flow monitoring and object type distinguishing without any auxiliary aided labeling.
