摘要
为了对各养殖场内的温湿度信号进行自动化采集、传输、存储和显示,提供全天候、无人看守、免维护的无线监控服务,基于ZigBee技术,采用CC2430射频芯片和温湿度传感器SHT11搭建了养殖场监测网络。文章主要探讨了无线传感网络的协调器主节点、各传感器节点的结构设计及程序流程,给出了上位机的软件设计。研究表明,采用SHT11高精度、高集成度的温湿度数字传感器以及CC2430芯片作为节点的主处理和射频模块,并利用节点的休眠功能可降低系统功耗,其无论在投入成本和数据检测精度上都基本符合设计要求。
In order to collect,transmit,store and monitor temperature and humidity signals in livestock farms and provide wireless monitoring service around the clock,we set up a monitoring network with CC2430 RF chip and humidity sensor SHT11 based on Zigbee technology.This paper mainly discusses the main nodes of coordinators of the wireless sensor network and the structural design of all the sensor nodes as well as programming procures and presents an upper PC software design.Research reach shows that using SHT11and high accurate and concentrated temperature and humidity digital sensor as well as CC2430 chip as the main processor and RF module of the nodes and the use of hibernation function can reduce system power consumption and can basically meet the requirement of design in terms of cost investment and data detection accuracy.
