职业:用于高密度远程水质监测的超低功耗嵌入式传感器

基本信息

项目摘要

In this five-year proposed CAREER project, newly developed ultra low-power chemical andturbidity sensors will work alongside low-power commercially-available temperature, pressureand flow sensors to provide high-density remote sampling of the watershed environment ineastern Kentucky.Scientific Merit:The scientific goal of this project is to build and use a low-cost sensor platform for real-timewater quality monitoring. Original research will be conducted into ultra low-power chemical andturbidity sensors. These micro- and nanofabricated components will be integrated into amacroscale sensor network using off-the-shelf wireless networking hardware and open-sourcesoftware that has recently become available. Wireless communication nodes will each connect todozens of low-power submersible sensors at different depths; since depths and sensor typesdepend on the application, a standard electrical and mechanical sensor interface will allow usersto easily customize the network. The end result will be a new set of low-cost research toolsavailable to help environmental and geological researchers ask new scientific questions, backedby the ability to carry out watershed monitoring projects with greater data resolution than everbefore.Broader Impact/Educational Activities:Educational activities focus on using the sensor network to monitor water quality in easternKentucky. Due to the rugged Appalachian terrain, previous studies of the region's water qualityhave not been carried out at high resolution. Mining, agriculture, and natural events contribute toboth degradation of water quality and changes in the hydrological dynamics of ground andsurface water flow, yet the impracticality of accessing a remote streambed during a storm, and thelow spatial density of conventional sampling, have made it difficult to pinpoint the source of achange in water quality without after-the-fact laboratory techniques. The broader impact of theseremote access real-time water quality maps will be an improved ability to monitor, understand,and mitigate sources of pollution affecting human and ecological communities.Two groups of Kentucky students, one in urban Louisville and another in rural easternKentucky, will participate in the project's educational activities. Sensor fabrication and testingwill be conducted at the University of Louisville by first-year students in our Introduction toEngineering curriculum. Because this project fits into the larger context of improving the naturalenvironment, it may attract students who have not previously considered majoring in electricaland computer engineering due to unfamiliarity with the purpose and variety of career options inthe field. These underrepresented students come disproportionately from the female and minoritypopulation.This project will also establish a collaborative link between the engineering school at theUniversity of Louisville and Eastern Kentucky University, which does not have an engineeringdepartment. Field testing, data collection, and analysis will be conducted by students at EasternKentucky University via the Eastern Kentucky Environmental Research Institute, which wascreated in 2005 with funds from the National Science Foundation's Experimental Program toStimulate Competitive Research (NSF-EPSCoR). Its purpose is to foster interdisciplinaryresearch into understanding the effect of environmental function on eastern and centralKentucky's land, air and water, and to encourage both undergraduate and graduate studentparticipation in the design and execution of research projects, particularly field-based researchactivities. Early in the project, professors, students and community members will specify sensorsto best complement the monitoring methods they are currently using. In return, they will obtainnew research instruments, and hands-on experience with cutting-edge wireless sensor network technology.
在这个为期五年的CAREER项目中,新开发的超低功耗化学和浊度传感器将与低功耗商用温度、压力和流量传感器一起工作,为肯塔基州东部的流域环境提供高密度的远程采样。科学价值:本项目的科学目标是建立并使用低成本的传感器平台进行实时水质监测。将对超低功耗化学和浊度传感器进行初步研究。这些微型和纳米制造的组件将使用现成的无线网络硬件和最近可用的开源软件集成到一个宏观传感器网络中。每个无线通信节点将连接数十个不同深度的低功率潜水传感器;由于深度和传感器类型取决于应用,标准的电气和机械传感器接口将允许用户轻松定制网络。最终的结果将是一套新的低成本研究工具,可以帮助环境和地质研究人员提出新的科学问题,并有能力以比以往更高的数据分辨率开展流域监测项目。更广泛的影响/教育活动:教育活动的重点是使用传感器网络监测肯塔基州东部的水质。由于阿巴拉契亚山脉地形崎岖,以前对该地区水质的研究并没有以高分辨率进行。采矿、农业和自然事件都会导致水质的退化以及地面和地表水的水文动态变化,然而,在暴风雨期间访问偏远河床的不切实际,以及传统采样的低空间密度,使得在没有事后实验室技术的情况下很难确定水质变化的来源。这些远程访问实时水质地图的更广泛影响将是提高监测、了解和减轻影响人类和生态社区的污染源的能力。肯塔基州的两组学生,一组在城市路易斯维尔,另一组在肯塔基州东部农村,将参与该项目的教育活动。传感器的制造和测试将由路易斯维尔大学工程入门课程的一年级学生进行。因为这个项目符合改善自然环境的大背景,它可能会吸引那些以前没有考虑过主修电气和计算机工程的学生,因为他们不熟悉该领域的目的和职业选择的多样性。这些未被充分代表的学生不成比例地来自女性和少数族裔。该项目还将在路易斯维尔大学的工程学院和没有工程系的东肯塔基大学之间建立合作联系。现场测试、数据收集和分析将由东肯塔基大学的学生通过东肯塔基环境研究所进行,该研究所于2005年由美国国家科学基金会刺激竞争性研究实验计划(NSF-EPSCoR)资助创建。其目的是促进跨学科研究,以了解环境功能对肯塔基州东部和中部土地,空气和水的影响,并鼓励本科生和研究生参与研究项目的设计和执行,特别是基于实地的研究活动。在项目早期,教授、学生和社区成员将指定传感器,以最好地补充他们目前使用的监测方法。作为回报,他们将获得新的研究仪器,并获得尖端无线传感器网络技术的实践经验。
