中文摘要: 在电力监测无线传感器网络中,由于节点环境变化、电磁干扰、测量误差、网络延迟等因素的客观存在,导致获得的感知数据经常是不确定的。围绕提高WSN中感知数据的质量,业已提出了很多方法。但这些研究工作大多都是针对一些WSN实验原型系统开展研究,且研究工作不系统,没有成熟的方法可供使用。为此,本课题以提高电力监测无线传感器网络中感知数据的质量为目的,重点研究:1)研究传感器节点采集数据质量控制技术,提高传感器节点的数据采集质量,减少错误或误差;2)研究不确定感知数据检测与修复方法,提高感知数据库的质量;3)研究容忍不确定感知数据的近似查询机制,获得满足电力系统运行需求的计算结果。利用已建立的无线传感器网络开发试验平台,对所提出的理论和方法进行验证,其研究成果将为无线传感器网络在电力系统中的大规模应用提供技术支撑。

英文摘要: Due to the objective factors such as measurement errors, network bandwidth limitation, communication unreliability, etc, the data captured by wireless sensor networks used to monitor power usage are often uncertain. There have some methods to improve the quality of sensor data in wireless sensor network. However, those researches are based on some experimental prototype system, and they are not systematic. To improve the quality of sensor data in power monitoring wireless sensor networks, this project will focus on the following issues. (1) To study the technology of data quality control in sensor node, aiming to improve the sensor data acquisition quality, and reduce errors; (2) To investigate error detection, recovery theory and algorithm over uncertain to improve the quality of sensor data; (3) To design uncertain data tolerance and approximate query technology, in order to obtain results that satisfy the demand of the power system. At last, we will verify our proposed theories and methods on our wireless sensor network platform. The research results of this project can provide technical support for wireless sensor networks to monitor a large scale power system.
