奶牛场无线传感器网络设计研究

Research on Design of Wireless Sensor Networks for Dairy Farms

针对奶牛养殖场数据采集时不易实现检测区域的完全覆盖和铺设线缆繁琐的问题,设计了由高性能、低功耗单片机ATmega32L和无线通信模块CRM2400CNC,建立奶牛养殖场无线传感器网络。同时,重点讨论了系统结构、传感器节点的硬软件设计和通信协议等关键问题,结合奶牛场的实际对系统结构的简化进行了研究,并提出了一种新的适合动态网络的跨层技术。试验结果表明,该系统具有结构简单、成本低、功耗低等特点。

Aiming at the current situation that dairy farms digital management system is difficult to cover the detection area and the tedious work of laying cables,this paper proposes a method to build a free communication system with high reliability,low consumption micro-processor ATmega32L,and the wireless communication module CRM2400CNC.The designs of system structure,hardware,software and protocols are discussed in detail.According to the actual conditions of dairy farms,the design of simplified architecture of WSN system and a new cross-layer network model are studied.The system has the characteristics of simple framework,low cost and low power.
