摘　　要：针对传统温室环境监测系统布线繁琐、维护困难等问题,基于ZigBee技术搭建无线传感器网络对温室环境信息进行采集,并通过网关将数据上传上位机,在上位机上开发人机交互界面便于实时监测。同时,为了降低WSN节点能耗,延长网络寿命,设计了1种基于RSSI的发射功率自适应机制。实验表明,该机制能够有效降低节点能耗,整个监测系统具有可靠性高、工作稳定等优点,能够满足温室环境监测的需求。Aiming at the problems of traditional greenhouse environment monitoring systems such as complicated wiring and difficult maintenance, this paper constructed a wireless sensor network based on ZigBee technology to collect environment information in greenhouse, designed the gateway node to send data to upper machine and developed an interactive interface on the host machine for monitoring. Meanwhile, an adaptive mechanism of transmit power based on RSSI is designed to reduce energy consumption and increase the lifetime of nodes. The experimental results show that the mechanism is helpful with energy saving and the whole system is proved with the advantages of high reliability, stable work and is able to meet the demand of environment monitoring in greenhouse.
