提出了一种基于无线传感器网络的水质监测传感节点设计方案,该节点由传感器模块、主处理器模块与无线通信模块和能量供应模块组成,其中传感器模块采用独立的模块结构,与主处理器之间由 RS-485 总线相连,主处理器与无线通信模块是以符合 IEEE 802.15.4 协议的 CC2430 芯片为基础设计的.多个传感器节点采用 Zig Bee 协议栈实现自组网,从而构建一个参数设置灵活、节点布置快速的水质自动监测系统.%A design scheme of water quality monitoring sensor node based on wireless sensor networks is presented. The node consists of sensor module, main processor module, wireless communication module and power supply module. The sensor module which is connected to the main processor by RS-485 bus uses separate sensor module structure. The main processor and the wireless communication modules are designed based on CC2430 chip which is consistent with the IEEE802.15.4 protocol. Several sensor nodes make up networks use Zig Bee stack protocal automatically to build up an automatic water quality monitoring system with flexible set up of parameters and rapid deployment of nodes.
