对重要基础设施(如桥梁)进行全面评估,采用结构健康监测(SHM)过程。SHM系统的开发和实现通常基于无线传感器网络(WSN)平台。然而,大多数WSN平台都是电池供电的,因此,电池寿命有限。功率约束通常通过应用能量收集(EH)技术来解决。因此,存在大量的WSN平台和EH技术。在开发和实施SHM系统期间,特定平台和技术的使用是重要因素,并且取决于各种操作条件。因此,有必要执行系统的文献综述(SLR)的WSN平台和EH技术在SHM的背景下的桥梁。尽管最先进的评论文章呈现了该领域的多个角度,缺乏对不同WSN平台和EH技术进行深入比较研究的SLR。此外,还需要系统分析,以探索其他设计考虑因素,如检查规模(全球/本地),响应类型(静态/动态),和传感器的类型。因此,本单反选择46篇文章(2007-2023年),与桥梁SHM中的EH技术和WSN平台有关。选定的文章分为三类:WSN平台,能量收集技术,以及两者的结合。随后,对WSN平台和EH技术进行了比较分析。此外,选定的文章(共=46)也在传感器类型方面进行了探索,检查刻度,和响应类型。因此,确定了17种不同的传感器类型。这项研究具有重要意义,因为它可以在选择适当的WSN平台期间促进域的各个利益相关者,EH技术,和相关的设计问题。
To perform a comprehensive assessment of important infrastructures (like bridges), the process of structural health monitoring (SHM) is employed. The development and implementation of SHM systems are generally based on wireless sensor networks (WSN) platforms. However, most of the WSN platforms are battery-powered, and therefore, have a limited battery lifetime. The power constraint is generally addressed by applying energy harvesting (EH) technologies. As a result, there exists a plethora of WSN platforms and EH techniques. The employment of a particular platform and technique are important factors during the development and implementation of SHM systems and depend upon various operating conditions. Therefore, there is a need to perform a systematic literature review (SLR) for WSN platforms and EH techniques in the context of SHM for bridges. Although state-of-the-art review articles present multiple angles of the field, there is a lack of an SLR presenting an in-depth comparative
study of different WSN platforms and EH techniques. Moreover, a systematic analysis is also needed for the exploration of other design considerations such as inspection scale (global/local), response type (static/dynamic), and types of sensors. As a result, this SLR selects 46 articles (during 2007-2023), related to EH techniques and WSN platforms in SHM for bridges. The selected articles are classified into three groups: WSN platforms, energy harvesting techniques, and a combination of both. Subsequently, a comparative analysis of WSN platforms and EH techniques is made. Furthermore, the selected articles (total = 46) are also explored in terms of sensor type, inspection scale, and response type. As a result, 17 different sensor types are identified. This research is significant as it may facilitate the various stakeholders of the domain during the selection of appropriate WSN platforms, EH techniques, and related design issues.
