一种适宜于农业监测和控制的WSN应用框架

A WSN Application Framework for Agricultural Environment Monitoring and Controlling

随着微电子系统、无线通信、信号处理等技术的飞速发展,无线传感器网络(WSN)作为一个新的研究领域已经成为国内外关注的热点。针对农业生产中的不同问题,国内外已有众多学者提出了多种基于WSN的解决方案,提高了生产效率。WSN在农业应用中涉及多个环节,包括田间信息采集、数据传输、信息的管理和显示。然而,已有的研究大多只关注WSN解决方案的各环节本身,较少提及各个环节之间的数据流及实现方法。针对WSN在农业应用中较多涉及的信息监测和自动控制,提出了一种适宜于农业监测和控制的WSN应用框架(WSNFFA),为WSN在农业中的应用提供了一个合理优化的解决方案。框架不仅描述了各层内部的关键技术和方法,而且给出了各层之间数据流传输方法,并搭建了基于WSNFFA的平台用于实现对苹果园环境的监测。实际运行结果表明:系统总体运行稳定,能满足农业环境监测的要求。

The WSN has become the research focus both at home and abroad with the development of microelectronics technique,wireless communication,signal processing technology etc.Many solutions have been proposed based on the WSN to solve the corresponding problem in agricultural production,and the production efficiency was improved.When applying the WSN to the agriculture,more than on segment was involved including the data collection in the farm,the data transmission,and the data management and display.However,most of the researchers paid much attention on the segment themselves,and the data stream between the adjacent segments was rarely involved.Most of the WSN applications in the agriculture were to realize data collection and controlling,a WSN application framework WSNFFA was proposed for agricultural monitoring and controlling.A reasonable and optimized solution was raised for the WSN application in the agriculture.The framework not only described the key technologies and methods in each segment,but also designed the data transmission method between the adjacent segments.A WSN platform was constructed following WSNFFA to monitor the apple orchard.The experimental results showed that the system run stably,and met the requirements for apple orchard monitoring.
