中文摘要：

作物生长与环境温度、光照强度、CO_2、土壤湿度等众多因素有关。为了及时掌握设施农业中各参数实时值以及随时间变化的关系。本文设计了一种基于ZigBee的多环境参数监测系统。系统采用星形网络结构,各传感器节点将采集的数据通过ZigBee网络传输给基站,基站对数据分析处理后通过串口传输给PC机,并以VB编写的上位机界面将各点环境参数按照与时间变化的关系以曲线的形式显示出来,通过上位机界面不但可以观看实时数据,还可以查询历史数据,为农作物管理提供了决策依据。

英文摘要：

Crop growth is connected with environmental temperature,light intensity,CO2,soil moisture and many other factors.In this paper,in order to know the real value of the parameters and the variation of parameters with time in the agricultural facilities in time,a multi-channel environmental parameters monitoring system was designed based on ZigBee.In the system,the star network structure was applied,each sensor node collected data through the ZigBee network transmission to the base station.After analyzing and processing,the data was transferred to PC through the serial port ,the environmental parameters of various points were displayed as curves according to the relationship with time by VB-programmed upper PC interface.Viaupper PC, not only real-time data could be viewed, but also the historical data could be queried, so as to provide the decision-making basis for crop management.
