摘要
在分析粮食科技物流中心的发展趋势的基础上,提出了一种基于SHT71的分层结构的温湿度监控系统,介绍了监控系统的网络结构。该系统以数字式温湿度传感器SHT71和STC单片机构成智能化的监控节点,结合触摸屏、GPRS模块构成仓房分布式监控系统实现温湿度的远程多点监控。对智能传感器节点电路及软件进行了设计,给出了详细的框图、程序流程图和组态画面。
After analysing the development trend of science and technology of grain , this paper proposes a kind of temperature and humidity monitoring system based on SHT71 hierarchical structure , and introduces the network structure about monitoring sys-tem . Intelligent control node of the distance system is formed by SHT71 （ the temperature ＆ humidity sensor ） and STC microcon-troller , combined with touch screen and GPRS modules , warehouse DCS monitor system can monitoring and control multi-locations temperature and humidity . Intelligent sensor node circuit and software are designed , and a detailed block diagram , process flow chart and configuration graph are given .
