基于无线传感器网络的温室智能监测系统研究

摘要

温室大棚内使农作物反季节生长的核心要素即为温度及湿度,因而对温度及湿度进行监测是至关重要的.针对当前通过人工采集模式及通过有线控制网络监测模式检测温湿度中所存在的问题,结合温室环境变化特性及采集要求,提出了利用无线传感器网络改进监测系统的思想,设计实现了一种基于ZigBee的温室智能监测系统,该系统由PC管理机节点、温室基站节点及传感器节点三部分组成.实验结果表明,该系统具有检测精度高、误差小及可靠性高的优点.%The key element for greenhouse to grow out -of -season fruit lies in specific temperature and humidity. So it is of great importance to read the temperature and humidity at the spot and to make adjustment accordingly. This research proposes a theory of using wireless sensor network to improve the monitoring system so as to solve the problems exiting in manual data collection mode and the mode of detecting temperature and humidity by wired control network. An intelligent greenhouse monitoring system based on ZigBee is designed, which is composed of three nodes at PC station, greenhouse base station and the sensor. The experimental results indicate that the system owns advantages of high detection precision, minimum error and high reliability.
