生活在你的脚下：一个端到端的土壤生态传感器网络，数据库，Web服务器和分析服务
Life Under Your Feet: An End-to-End Soil Ecology Sensor Network, Database, Web Server, and Analysis Service
摘要：
无线传感器网络可以通过提供以前不可能的时间和空间粒度的测量来彻底改变土壤生态学。本文介绍了一个土壤监测系统，我们开发和部署在巴尔的摩的城市森林实现这一愿景的第一步。这个网络中的微粒每分钟都在现场测量和保存土壤湿度和温度。原始测量值由传感器网关定期检索，并存储在中央数据库中，其中导出并存储校准版本。测量数据库通过Web Services接口发布。此外，分析工具让科学家分析当前和历史数据，并帮助管理传感器网络。本文介绍了系统设计，我们从部署中学到了什么，以及从传感器获得的初步结果。该系统以前所未有的时间精度测量土壤因素。然而，部署需要设备级编程，跨空间和时间的传感器校准，以及与外部源的交叉参考测量。数据库、Web服务器和数据分析设计需要大量的创新和专业知识。计算机科学家和生态学家的比例是3：1。在传感器网络能够发挥其作为科学家可以轻松部署的工具的潜力之前，这些技术问题必须得到解决，以便比率是每十个生态学家中有一个书呆子。
英文摘要：
Wireless sensor networks can revolutionize soil ecology by providing measurements at temporal and spatial granularities previously impossible. This paper presents a soil monitoring system we developed and deployed at an urban forest in Baltimore as a first step towards realizing this vision. Motes in this network measure and save soil moisture and temperature in situ every minute. Raw measurements are periodically retrieved by a sensor gateway and stored in a central database where calibrated versions are derived and stored. The measurement database is published through Web Services interfaces. In addition, analysis tools let scientists analyze current and historical data and help manage the sensor network. The article describes the system design, what we learned from the deployment, and initial results obtained from the sensors. The system measures soil factors with unprecedented temporal precision. However, the deployment required device-level programming, sensor calibration across space and time, and cross-referencing measurements with external sources. The database, web server, and data analysis design required considerable innovation and expertise. So, the ratio of computer-scientists to ecologists was 3:1. Before sensor networks can fulfill their potential as instruments that can be easily deployed by scientists, these technical problems must be addressed so that the ratio is one nerd per ten ecologists.
