基于GPRS的土壤温湿度采集系统

设计了一种基于GPRS的土壤温湿度实时采集系统,给出了一种基于无线传感器网络的环境监测方案。无线传感器网络是由大量随机分布的传感器节点,通过无线通信技术自组织构成的网络,传感器节点具有数据采集处理、无线通信和自动组网能力。文中利用Telosb节点平台设计了传感器节点的硬件结构,并在TinyOS操作系统的基础上,完成了节点的软件设计。该系统可以对目标监测区内多点的温湿度进行实时采集,实现单跳和多跳的数据传输,同时利用GPRS进行高效可靠的远程传输,实现长期动态监测。

Design of Soil Moisture and Temperature Real-time Monitoring System Based on GPRS

This article presents a soil temperature sampling system based on the GPRS and an environment survey plan based on the wireless sensor network.The wireless sensor network consists of a large number of wireless sensor nodes which are randomly distributed.All theses nodes are connected with each other by wireless communication technology,capable of data sampling,processing,wireless communication and auto network connection.Telosb platform is used to complete the design of the hardware structure of the sensor nodes and the software design is completed on the TinyOS.The whole system can solve the humidity and temperature sampling problems for the target zone,realizing both the single and muti-hop data transfer meanwhile the long term dynamic surveillance can be also realized by efficient and reliable GPRS long range transmission.
