基于无线传感网络的自动气象站节点的设计

Design of Automatic Weather Station Node Based on Wireless Sensor Network

针对目前自动气象站布线复杂、成本高、维护不方便等情况,介绍一种基于无线传感网络的自动气象站节点,阐述该自动气象站节点的总体设计、硬件结构和驱动程序。该节点以S3C2410作为主控芯片进行数据处理,以CC2420作为无线射频芯片进行数据传输。经测试,使用该节点可降低布线成本,使数据传输更加稳定可靠。

Aimed at several disadvantages of present automatic weather station, such as complex routing, high cost and difficult maintaining, an automatic weather station node was introduced based on wireless sensor network, including its general design, hardware structure and driver program. S3C2410 was adopted as the main-control chip to process data, and CC2420 was used as the wire- less radio frequency chip to transmit data. Test results indicate that present design can reduce the design cost and enhance the stability of data transmission.
