本文概述并讨论了智慧城市方法在城市地下基础设施测绘和状况评估方面的一些相关细节。地下设施是所有现代城市的关键基础设施。它们携带饮用水、雨水、污水、天然气、电力、电信、蒸汽等。在大多数城市，地下基础设施反映了城市的发展和历史。许多组件老化，在未知的位置和拥塞配置中，处于未知的状态。该技术利用传感和信息技术来确定基础设施的状况，并以适当、及时和安全的方式提供给管理人员、规划人员和用户。传感器包括探地雷达和埋地传感器，用于持续感知局部条件。信号处理和模式识别技术转换信息数据库中的数据，用于分析、图形表示、计量和规划。本文的数据来自佛蒙特州伯灵顿市圣保罗街CCTA公交车站项目的建设；VT .威诺斯基的公用事业更换场地；以及智能手机位置注册和磁信号的实验室测试。所遇到的土壤条件对探地雷达传感有利，可以定位埋管和土层。目前的技术水平是，数据收集和处理过程是手动的，有些繁琐，但自动化这些过程的解决方案似乎是可行的。移动永磁体的磁信号有可能通过其他电磁波基本上无法穿透的土壤发送低频遥测信号。
This paper outlines and discusses a few associated details of a smart cities approach to the mapping and condition assessment of urban underground infrastructure. Underground utilities are critical infrastructure for all modern cities. They carry drinking water, storm water, sewage, natural gas, electric power, telecommunications, steam, etc. In most cities, the underground infrastructure reflects the growth and history of the city. Many components are aging, in unknown locations with congested configurations, and in unknown condition. The technique uses sensing and information technology to determine the state of infrastructure and provide it in an appropriate, timely and secure format for managers, planners and users. The sensors include ground penetrating radar and buried sensors for persistent sensing of localized conditions. Signal processing and pattern recognition techniques convert the data in information-laden databases for use in analytics, graphical presentations, metering and planning. The presented data are from construction of the St. Paul St. CCTA Bus Station Project in Burlington, VT; utility replacement sites in Winooski, VT; and laboratory tests of smart phone position registration and magnetic signaling. The soil conditions encountered are favorable for GPR sensing and make it possible to locate buried pipes and soil layers. The present state of the art is that the data collection and processing procedures are manual and somewhat tedious, but that solutions for automating these procedures appear to be viable. Magnetic signaling with moving permanent magnets has the potential for sending lowfrequency telemetry signals through soils that are largely impenetrable by other electromagnetic waves.
