摘　　要：为了有效实施农业大棚温度动态实时监控,提出采用Zigbee无线网络和Linux嵌入式操作系统设计大棚温度监控系统。系统采用C/S结构设计,分为下位机和上位机2部分。下位机系统分为温度采集节点和汇聚节点,温度采集节点完成大棚内不同地点的温度信息采集和无线数据传输功能;汇聚节点除了完成数据中继任务外,还可根据上位机反馈的控制指令完成排风扇的打开或电热系统的开启工作;服务器端的上位机系统完成数据的储存和分析,并根据分析结果完成对下位机系统的实时控制。实践证明,该系统可精确监控大棚温度,有效降低布线成本,有助于降低劳动成本和提高农作物产量。In order to dynamically real-time monitor the agricultural greenhouse temperature effectively, it proposed to designing a greenhouse temperature control system based on Zigbee wireless network and Linux embedded operating system. The system designed with C/S structure, was composed of lower computer and upper computer in two parts. The lower computer system including temperature acquisition nodes and aggregation nodes： the temperature acquisition nodes complete function of temperature information collection and wireless data transmission in different locations inside the greenhouse, aggregation nodes in addition to completing the data gathering tasks can turn on the fans or heating systems according to feedback control commands from upper computer. The server-side upper computer system stores and analyzes data, and real-time controls lower computer system according to its analysis results. It had proved in practice that the system can accurately monitor the greenhouse temperature, effectively reduced wiring costs and it is helpful to reduce labor costs and increase crop yields.
