摘　　要：设计一种基于ZigBee的室内监控系统,该系统采用低功耗无线收发芯片CC2530及传感器构建室内局域网,包含物联网的感知层、网络层及应用层三层结构,传输协议选用ZigBee;感知层包括温湿度、光敏、摄像头图片数据采集;网络层主要是ZigBee无线网络,数据汇聚至网关;应用层包括手机、PC机等;网络拓扑结构采用星形网络结构;给出软硬件实现方法,主要有节点设计、网络组建及软件设计等;实验在长6m宽3m的室内进行,测试正常室温,温度传感器附近放置低于室温10℃和高于室温10℃物体改变环境温度;光敏传感器测试采用日照强度,遮挡及部分遮挡传感器改变光照强度;人员在摄像区域内外移动测试摄像清晰度及监控范围;测试结果表明系统工作正常,PC机终端软件显示各传感器随环境变化相应变化值。This paper designs an interior monitoring system based on ZigBee. The system adopts CC2530 wireless receives ~ sends chip and sensor to construct interior local area network including perception layer, network layer and application layer. Transfer protocol adopts ZigBee. Perception layer includes temperature, humidity, and light, camera data collecting. Network layer includes ZigBee wireless network and data is converged to gateway. Network topology is star network. The realization of hardware and software is presented, including termi- nal node design, network construction and software realization, etc. Experiments were accomplished in the indoor with 6 m length and 3 m width. Temperature sensors were tested by changing circumstance temperature reaches 10 degrees below or above the room temperature. Op- tic sensors were tested by changing sunlight intensity. The definition and range of cameras were tested when people entered or left the exam area. Tests indicate the system can stably run and PC can display sensor variation with the circumstances.
