Abstract Guided waves based structural health monitoring systems have been proposed to ensure reliability and structural integrity of pipelines. These systems are designed with permanently attached transducers that are able to detect automatically early state damage that could occur during the lifetime of a pipeline. Actually, the transducers are responsible for generating ultrasonic guided waves signals which propagate through the pipeline and interact with damage. Therefore, the interpretation of the received signals leads to ascertain if the pipeline is damaged or not. However, these signals are very complicated and may contain not only information about damage, but also the effects of environmental and operational conditions (temperature, flow rate etc.) and the effects of the transducers issues (fracture, debonding etc.). If these effects are not taken into account they would result in false indication of damage (false alarm). This paper presents a literature synthesis review of different methods and strategies that have been developed to reduce false alarms during in-situ monitoring of pipelines using guided ultrasonic waves technique. A critical view of each method is provided to determine which method is suitable for which context. Basing on this review and the field experience of the authors, recommendations are provided in order to help designers and practitioners in their decision-making. Although the paper focuses on pipeline safety, the recommendations could be applicable to other structures such as (rails, plates, cables etc.).

减少管道导波结构健康监测中的误报:综述和辩论

摘要 已经提出了基于导波的结构健康监测系统来确保管道的可靠性和结构完整性。这些系统设计有永久连接的传感器,能够自动检测管道使用寿命期间可能发生的早期状态损坏。实际上,换能器负责产生通过管道传播并与损坏相互作用的超声波导波信号。因此,接收信号的解释导致确定管道是否损坏。然而,这些信号非常复杂,可能不仅包含有关损坏的信息,还包含环境和操作条件(温度、流速等)的影响以及换能器问题的影响(断裂、脱粘等)。如果不考虑这些影响,它们将导致错误的损坏指示(错误警报)。本文对已开发的不同方法和策略进行了文献综合综述,这些方法和策略是在使用引导超声波技术对管道进行现场监测期间减少误报。提供了每种方法的关键视图,以确定哪种方法适用于哪种上下文。根据这篇评论和作者的现场经验,提供了一些建议,以帮助设计师和从业者做出决策。尽管本文侧重于管道安全,但这些建议也适用于其他结构,例如(栏杆、板、电缆等)。本文对已开发的不同方法和策略进行了文献综合综述,这些方法和策略是在使用引导超声波技术对管道进行现场监测期间减少误报。提供了每种方法的关键视图,以确定哪种方法适用于哪种上下文。根据这篇评论和作者的现场经验,提供了一些建议,以帮助设计师和从业者做出决策。尽管本文侧重于管道安全,但这些建议也适用于其他结构,例如(栏杆、板、电缆等)。本文对已开发的不同方法和策略进行了文献综合综述,这些方法和策略是在使用引导超声波技术对管道进行现场监测期间减少误报。提供了每种方法的关键视图,以确定哪种方法适用于哪种上下文。根据这篇评论和作者的现场经验,提供了一些建议,以帮助设计师和从业者做出决策。尽管本文侧重于管道安全,但这些建议也适用于其他结构,例如(栏杆、板、电缆等)。提供了每种方法的关键视图,以确定哪种方法适用于哪种上下文。根据这篇评论和作者的现场经验,提供了一些建议,以帮助设计师和从业者做出决策。尽管本文侧重于管道安全,但这些建议也适用于其他结构,例如(栏杆、板、电缆等)。提供了每种方法的关键视图,以确定哪种方法适用于哪种上下文。根据这篇评论和作者的现场经验,提供了一些建议,以帮助设计师和从业者做出决策。尽管本文侧重于管道安全,但这些建议也适用于其他结构,例如(栏杆、板、电缆等)。
