The use of wireless sensors for bridge assessment has been investigated extensively in the past decades. However, in most field applications, current sensors and sensing systems still rely on wired connectivity for communication and power. This is the case even though tethered sensors require extensive cabling throughout a structure resulting in long installation processes, and their maintenance may increase the total cost of Structural Health Monitoring systems and impede their broader use, especially when rapid infrastructure assessment is needed. One possible explanation of this slow adoption of wireless sensors is the use of sensing units that have not been tested for decades as their wired counterparts. This paper presents a suite of wireless sensors that were developed through the transformation of established wired sensors into wireless units. The objective was to explore whether it was possible to transform such wired sensors into wireless units and then confirm successful transformation with laboratory and field applications. The sensors presented here focus on accurate measurements of displacement, strain, and acceleration with units that are rugged, have a long service life and are used primarily for rapid structural assessment. With this transformation, the authors wanted to accomplish the goal of rapid installation and sensing reuse, and achieve accurate wireless measurements guaranteed by the wired sensors of established sensing vendors. In this study, the wireless sensors were tested first in laboratory conditions along with wired sensors for comparison and then were successfully tested in the field.

使用有线传感器衍生的无线传感系统，对公路结构变形进行快速，稳健的测量

在过去的几十年中，已经广泛研究了使用无线传感器进行桥梁评估。但是，在大多数现场应用中，当前的传感器和感测系统仍依赖有线连接来进行通信和供电。即使系留传感器需要在整个结构中进行大量布线，导致安装过程较长，情况仍是如此，并且其维护可能会增加结构健康监测系统的总成本并妨碍其广泛使用，尤其是在需要快速基础架构评估的情况下。无线传感器这种缓慢采用的一种可能解释是使用了几十年来未经过测试的传感单元作为其有线对应单元。本文介绍了一套无线传感器，它是通过将已建立的有线传感器转换为无线单元而开发的。目的是探索是否有可能将这种有线传感器转换为无线单元，然后确认在实验室和现场应用中是否成功转换。此处介绍的传感器专注于使用坚固耐用，使用寿命长且主要用于快速结构评估的单元对位移，应变和加速度进行精确测量。通过这种转换，作者希望实现快速安装和传感重用的目标，并通过已建立的传感供应商的有线传感器来保证准确的无线测量。在这个研究中，
