摘要
针对传统温室监控系统成本高、移动性差的问题,设计了基于无线传感器网络的嵌入式温室监控系统。介绍了系统的整体结构,分别以S3C2410和MSP430F149为核心设计了汇聚节点与子节点的结构组成,实现了系统的硬件基础。在此基础上,又提出了一套适用于该系统的无线网络通信协议,规定了无线通信的数据传输格式。同时,还规划了汇聚节点的工作流程。最后通过采用休眠-唤醒模式,使节点的寿命得到了显著提高。WSN的引入精简了通信线路铺设,缩短了工程建设周期,方便了系统维护与扩展,并对提高温室管理水平和国家发展农业自动化具有重要意义。
An embedded greenhouse monitoring and control system based on wireless sensor networks was presented, in order to solve problems in traditional systems, such as high maintenance cost and low mobility. This paper introduced the overall structure of system, and then accomplished hardware platform of system by means of designing the architectures of sink-node and leaf- node. Based on this, a suitable protocol of wireless communications which set the standards of data packet was proposed. The flow chart of nodes was programmed carefully as well. Finally, it extended the lifetime of nodes by adopting the sleep-wake mode. The introduction of WSN simplified the laying of communication lines and reduces its construction period, moreover, facilitated the maintenance and update of the system. It is significant for improving management of greenhouse and development of national agricultural automation.
