中文摘要：

将无线传感器网络技术应用于水情信息采集系统,用无线传输方式替代传统的有线传输方式,方便用户使用,降低安装和维护成本。用高性能的微控制器C8051F和低功耗的无线通信模块CC1020设计汇聚节点,采用基于时隙的通讯协议接收传感器节点发送过来的水情数据,用串行口通过GPRS将数据发送给信息中心。系统有很好的灵活性和扩展性,为水资源管理和农业生产提供技术支持,具有广阔的应用前景。

英文摘要：

Applying wireless sensor network technology to water regime collecting system and replacing the traditional cable transmission with the wireless transmission can reduce installation and maintenance costs and is convenient for users.This system designs the sink nodes with high-performance single-chip microcontroller C8051F and low-power communication module CC1020,receives the water regime sensor node data using the protocol which based on time slot,then sends the data through UART to information center by GPRS.It has good flexibility and scalability,can provide technical support for water resources management and agricultural production,and has a broad application prospect.
