基于GPRS的无线传感器网络数据中转器的设计

介绍了数据中转器的必要性和GPRS网络的特点和连接方法，提出了一种嵌入式数据采集无线传输的方法。采集数据通过ZigBee网络传至汇聚节点再传到数据中转器ARM芯片，ARM芯片完成采集数据存储和无线数据传送的功能。采集数据存储在铁电存储器中；无线数据传送部分采用SIM300C模块，通过GPRS网络将采集的数据传送到远程服务器上。该软件设计方案不仅满足系统实时性要求，而且具有数据传输稳定、可靠等优点。

Design of Wireless Sensor Network Data Transponder Based on GPRS

The necessity of data transponder and the features and the connection method of GPRS are introduced, a way that is applied to the embeded data acquisition and the wireless data transmission is proposed. Data acquired are transferred to the sink nodes via ZigBee network firstly, and then the sink nodes transfer the data to ARM chip of the data transponder which implements the functions of data storage and wireless data transmission. Data acquired are stored in Ferroelectric Nonvolatile RAM and transmitted to the remote server via GPRS network by using SIM300C module. The design of software not only fulfills the requirement of being a real-time system, but also guarantees the stability and reliability of data transmission.
