Abstract: Water attainment detection lays the foundation for optimal use of water resource. Wireless sensors are used to sampling water. Data of sampling is sent by Wireless Sensor Network(WSN) to base station in which data fusion is handled. After receiving the sampling data, the data server implements application decision. Based on a three-level structure of WSN, base station and data server, water attainment sampling algorithms by predicate are designed and simulated. Experimental result shows the practicability and high-efficiency of the algorithm.

Key words: Wireless Sensor Network(WSN), predicate, water attainment detection, sampling algorithm, data fusion

摘要： 水质达标检测是水资源优化利用的基础。利用无线传感器对水质进行采样，通过无线传感器网络将达标结果发送给基站进行融合处理，数据服务器在接收到采样数据后实施应用决策。在无线传感器网络、基站和数据服务器三层结构的基础上讨论基于谓词的水质达标采样算法，对算法进行分析、设计和仿真。实验结果表明，该算法实用且高效。
