基于ZigBee网络的温室环境远程监控系统设计与应用

针对温室环境数据信息监控特点，本文进行了基于ZigBee协议的传感器节点技术的开发，并在此基础上组成现场监控无线传感器网络，通过网络汇聚节点与无线移动网络（GPRS/CDMA）和INTERNET的无缝连接，实现数据远程传输至指定数据库服务器。无线传感器网络组建采用星型拓扑结构，通过软件设置在需求时唤醒ZigBee网络节点，使监控设备具有组网灵活、拆移便捷等优点。通过在实际生产过程中应用表明，该系统工作性能稳定，在数据采集和传输等方面均达到了设计要求，尤其是有效简化了现场设备安装与拆移等过程，使之更适合各类农业现场数据监控的需要。

Design and application of ZigBee based telemonitoring system for greenhouse environment data acquisition

Focused on the data and information monitoring of greenhouse environment, in this paper, the design and development of sensor node technology were introduced, and wireless sensor network of field monitoring was constructed based on ZigBee protocol. Through network sink node as well as integrating wireless mobile network (GPRS/CDMA) with INTERNET, field acquired data were transmitted to designated database server. The star-type network topology was adopted for the wireless sensor network which could be awakened up by software settings in the requirements and had many advantages, such as moving conveniently, flexible networking. The applicable results in the practical production show that the working performance of the system is quite stable and can reach the design requirements in real-time data acquisition and remote transmission. Especially, by effectively simplifying the design of field communication wiring and device installation, it becomes more useful and convenient in data monitoring in different kinds of agricultural sites.
