项目摘要

Modern societies depend critically on their transportation infrastructure, in particular on the networks of roads. Hence, there is a growing need for an accurate and reliable assessment of the structural health condition of roads, especially of their subsurface courses (layers) responsible for roads’ structural strength and performance. The approaches to addressing these needs must be pervasive, scalable, sustainable, wireless, low-cost, low-power, high-resolution, and deployable for long durations of time, with negligible disturbances to the courses. Currently, existing monitoring techniques fall short of fulfilling these requirements, in one way or another. The project seeks to develop foundational technology that addresses this challenge. The key enablers of the proposed technology are tiny wireless Backscatter-based, Batteryless, Radiofrequency Sensors (BBRS), which sense the communication channel between themselves while communicating using backscatter modulation. BBRS measure the phase and amplitude of the communication links, which allow discerning of various material properties, and enable simultaneous monitoring of distances, relative displacements, strain, cracking, stiffness, humidity, and temperature throughout continuums of subsurface courses. BBRS are powered by an external RF signal provided by exciters installed on moving vehicles; the same RF signal which supplies the carrier for the backscattering. Information is carried among BBRS via multihop networking. BBRS are able to carry out some basic data processing. The aim of this project is to generate preliminary results to demonstrate the feasibility of multiparameter, almost-continuous monitoring of pavement subsurface courses enabled by embeddable BBRS; protocols that enable readout from thousands of densely dispersed embedded BBRS using mobile exciters and receivers; and physics-informed machine learning algorithms for evaluation of current condition and performance of monitored courses, and for predictive modeling of their deterioration over time.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
现代社会严重依赖其交通基础设施,特别是道路网络。因此,越来越需要准确和可靠地评估道路的结构健康状况,特别是负责道路结构强度和性能的地下层(层)。解决这些需求的方法必须是普遍的、可扩展的、可持续的、无线的、低成本的、低功耗的、高分辨率的,并且可以长时间部署,对课程的干扰可以忽略不计。目前,现有的监测技术或多或少都不能满足这些要求。该项目旨在开发解决这一挑战的基础技术。该技术的关键实现因素是微型无线后向散射、无电池射频传感器(BBRS),它们在使用后向散射调制进行通信时感知彼此之间的通信信道。BBRS可以测量通信链路的相位和振幅,从而可以识别各种材料特性,并可以同时监测整个地下连续体的距离、相对位移、应变、开裂、刚度、湿度和温度。BBRS由安装在移动车辆上的激励器提供的外部射频信号供电;为后向散射提供载波的相同射频信号。BBRS之间通过多跳网络传输信息。BBRS能够进行一些基本的数据处理。该项目的目的是产生初步结果,以证明采用嵌入式BBRS对路面地下过程进行多参数、几乎连续监测的可行性;使用移动激励器和接收器从数千个密集分散的嵌入式BBRS读取数据的协议;以及基于物理的机器学习算法,用于评估监测课程的当前状况和性能,并对其随时间的恶化进行预测建模。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
