Abstract
针对无线传感网络节点在采集数据时存在大量冗余信息、数据准确性不高及系统监控不方便的问题，提出了一种基于无线传感网的数据采集及远程监控系统的设计方案。系统利用WSN节点完成对外部环境各参数的实时采集，对WSN节点的网络组建、数据传输、数据融合及传输到上位机进行了软件设计，并通过WIFI作为传输手段，构建了远程监控平台。测试结果表明，该系统可实现对外部环境远程实时监测，且使用数据融合算法使得节点间传输速率增大和数据准确性提高。 A data acquisition and remote monitoring system based on technique of WSN for solving the prob-lems of a large number of redundant data, low data accuracy and monitoring inconvenient was put forward when WSN nodes collect data. The system finished real-time acquisition of external envi-ronment parameters by WSN nodes and a software design for building network, data transmission, data fusion and transmit to the monitoring center. A means of transmission by WIFI was to build the remote monitoring platform in system. Test results indicate that: the system can accomplish remote monitoring for external environment and improve data accuracy and transmission rate by using data fusion.
