针对现有水环境监测手段的不足之处，可以把无线传感器 络技术应用到水 环境监测中，设计并制作面向水环境监测的无线传感器 络监测节点，为野外获 取研究数据提供方便。根据水质监测无线传感器 络节点设计的要求，设计了4 个模块：传感器模块、信号调理模块、CC2430 模块和电源模块。通过PH 传感 器、溶解氧传感器采集监测水域的PH 值和溶解氧含量，为了保证CC2430 模块 对信号的正确处理，需要将采集到的数据送入信号调理电路，经过信号调理电路 之后的信号是经过放大的较为稳定的信号，再由CC2430 模块的A/D 转换将模拟 信号转换为数字信号，然后进行数据处理和数据传输。最后利用无线传感器 络 特有的自组 特点，实现对被监测区域水环境的实时监测。 关键词 水质监测，无线传感器 络，节点设计 Title The Node Design of Wireless Sensor Networks for Water Q ality Monitoring Abstract In view of the existing deficiencies of the way for water q ality monitoring, the wireless sensor networks technology can be applied to the water q ality monitoring. The wireless sensor networks nodes were designed for water q ality monitoring which provide the convenience of the data acq isition o tside. According to the req irements of the node design of wireless sensor networks for water q ality monitoring, fo r main parts were incl ded: the sensor mod le, the signal conditioning mod le, the CC2430 mod le and the power mod le. By sing the sensors of PH and the sensors of dissolved oxygen, the val es of PH and dissolved oxygen are collected. In order to ens re processed by CC2430 mod le acc rately, the collected data sho ld be sent to the conditioning mod le. And the signal which is amplified and stabilized in conditioning mod le are converted from the analog signal to the digital signal by the A/D channel of CC2430. After that, the data processing and transmission can be carried o t. At last, the real time monitoring for water q ality is realized with the pec liar characteristics - ad hoc network of wireless sensor networks.
