采用ZigBee技术的温室环境监控系统设计

Design of greenhouse environment monitor system based on ZigBee technology

为了解决我国北方冬季寒冷干旱地区蔬菜种植的问题,最佳的温室气候所发挥的作用变得更加显著。设计实现基于ZigBee技术的温室环境监测系统,给出了系统的总体方案。结合温室环境变化特性及采集要求,给出了网络中节点硬件和软件的设计方案,构建无线数据采集网络。该系统把某区域采集到的温湿度参数数据传送到ZigBee协调器节点,再由协调器节点传输到PC。然后,在IAR IDE环境中对无线传感器节点程序进行设计和调试,从而实现对温室环境的监测与控制。实验表明该系统运行效果良好,被测数据可以实时上传到上位机进行显示和记录。

In order to solve the problems of planting vegetable in northern cold-arid areas, the optimal greenhouse climate adjustment plays the very important role. The design and implementation methods of greenhouse environmental monitoring system based on ZigBee technology were proposed and system＇ s overall program was constructed. Combined with environment change and collect requirement, hardware design and software solution are given, so that constructed data colIecting network. The system collects the temperature and humidity data to transport to ZigBee coordinator, and then uploads to PC. The wireless module software is programmed in IAR 1DE, which implements measuring and controlling greenhouse. Tests indicate that the system runs well, and data can be uploaded to host compuler for real-time display and record.
