在社会信息化的推动下，作为其核心的数字化技术已步入研究开发阶段。为了实现粮库的温湿度自动检测，提高粮库储粮的安全性是粮库管理实现自动化、智能化。我们提出基于ZigBee多点粮库温湿度检测的方案。为此论文开展于无线传感器网络技术的温湿度数据采集系统的研制工作。ZigBee无线传感器网络是一种新兴的传输技术，将其应用于室内温度和湿度的采集，进而构成无线温湿度采集系统。论文介绍了无线传感器网络系统的体系结构及关键技术。-In society, driven by information technology, as part of its core digital technology has entered a stage of research and development. Depot in order to achieve automatic detection of the temperature and humidity to enhance the security of grain storage grain depot management is automated, intelligent. ZigBee Based on our multi-point detection of grain temperature and humidity program. Carried out for this thesis in the wireless sensor network technology, temperature and humidity data acquisition system development. ZigBee wireless sensor networks is a new transmission technology, will be applied to the indoor temperature and humidity of the collection, which constitutes a collection system of wireless temperature and humidity. This paper introduces wireless sensor network system architecture and key technologies.
