摘 要: 在温室栽培中,温度是作物培育的重要参数,但是采用一般的办法并不能完成实际需求任务。针对这一问题,提出一种以Zigbee为基础、无线网络为媒介的温室栽培温度监测系统。使用Zigbee协议栈搭建网状拓扑的无线网,网络终端为插在土壤中的传感器节点,采集土壤的温湿度数据,利用无线网络,数据发送到网关后并上传到控制端,再由控制端的监控系统对数据进行相关的再处理。通过简单操作,节点可以快速、灵活地组成无线传感器网络,整个网络性能稳定,可靠性强。开发的Zigbee无线传感器网络不仅可以在温室中应用,还可以将其作为一个后期继续研究的开放平台。

Abstract:In greenhouse cultivation temperature is an important parameter of crop cultivation but the general method can not fulfill the actual required task. Aiming at this problem a kind of greenhouse cultivation temperature monitoring system based on Zigbee and wireless network is proposed. Zigbee protocol stack is used to build mesh topology of wireless networks network terminal is the sensor node inserted in a soil which could collect soil temperature and humidity data;using the wireless network after the data sent to the gateway and uploaded to the control side the data is related to processing again by the control of the monitoring system. Through simple operation the node can quickly and flexibly set up the wireless sensor network. The whole network performance is stable the reliability is good. The developed Zigbee wireless sensor network not only can be used in the greenhouse but also can be used as an open platform for further research.

引言
温室栽培是现代农业的主要内容之一,也是作物培养和农业研究的必要手段。重点是基于温室环境和各种调控方为作物提供最适宜的生长条件,摆脱季节和环境的制约,实现农产品的全年供给[1]。而在当前国内的基础运营中却已发现农业生产过程现代化程度较低、缺少温室支持的相关技术等问题。针对这一现状,就需要对温室环境融入更多的自动化调控,为农业生产中的作物生长这一环节创造智能有利的技术支持。然而,由于人工培育主要依托经验而难以臻至精确,无法将土壤温湿度实时控制在适宜范围内。因此,研究经济实用而设计合理的温室土壤监测系统则尤显得必要与重要。
