无线温室信息监测系统设计

Design of Wireless Surveillance System in Greenhouse

针对传统温室监控系统存在成本较高、可靠性和移动性较差等问题,设计了一种无线温室信息监测系统。文中介绍了系统整体架构,设计了传感节点的硬件结构并基于此提出了适用于温室环境的无线通信协议,协议中规定了传输方式和数据格式,最后通过试验证明,休眠-唤醒模式能够有效延长传感节点的待机时间。将WSN引入温室监控,对于精简通信线路铺设,缩短工程建设周期,方便系统维护更新,提高接口扩展性能都具有重要意义。

This paper designs a novel wireless surveillance system in greenhouse,in order to solve long-existing problems in tradi-tional systems,such as high maintenance cost,low robustness and mobility,etc.We first introduce the system architecture,with hardware structure defined and carefully designed on sensor,then we proposed the wireless communication protocol including trans-mission and data format applicable in the greenhouse.Experiments showed sleep-wake mode increased lifetime of sensors quite effi-ciently.The introduction of WSN has remarkable meaning in the design of greenhouse surveillance systems,as it could not only sim-plify the design of communication circuitry so as to reduce the period of the whole system implementation;but also extend the func-tion and performance of interfaces,then facilitate the maintenance and update of the system.
