摘　　要：为解决现有室内环境监测系统存在的布线繁琐,成本高,功耗大等问题,设计了一种基于无线传感器网络(WSNs)的远程室内环境监测系统。以CC2530为核心开发无线传感器节点,完成对环境因子的监测。基于Cortex-A7微处理器MT7623A和Linux构建网关节点,兼具高性能路由器与Zig Bee协调器的功能。将节点所采集的数据发送至远程服务器,并通过二级数据融合对环境质量进行评估。初步实验表明:系统具有低功耗、组网灵活、扩展性强等优点,能够较好地满足室内环境监测的应用需求。A remote indoor environment monitoring system based on wireless sensor networks （WSNs） is designed to deal with problems in current indoor environment monitoring system, such as complicated routing, high cost, high power consumption. Environmental factors monitoring is achieved by developing wireless sensor node which chooses CC2530 as the core. Gateway node is structured based on Cortex-AT MT7623A microprocessor, and Linux operating system, which has functions of high-performance router and ZigBee coordinator. The data collected by sensor node is sent to remote server,and the environment quality grade is evaluated through two-level data fusion. Preliminary experiments show that the system which has advantages of low power consumption, flexible networking and strong expandability, which meet the application requirements of indoor environment monitoring excellently.
