智能技术的不断发展，如无线传感器网络、微机电系统（MEMS）、计算机视觉、光纤和先进的数据解释技术，可能会彻底改变结构健康监测（SHM）。桥梁资产的专用SHM有可能产生有价值的数据集，并为业主和管理人员提供信息，以帮助解决关键问题，例如：当前性能，安全裕度，实际载荷，应力历史和疲劳风险，劣化程度和剩余寿命。然而，从资产所有者、设计者、承包商和研究人员等不同利益攸关方的角度来看，所测量的参数和所获得数据的价值将有所不同。在本文中，监测的目的进行审查。提出了一种方法，以促进在指定任何部署之前主要利益攸关方之间的正式讨论，并确保稀缺资源不会浪费在追求数据而不是信息上。
On-going developments in smart technologies such as wireless sensor networks, micro-electro-mechanical systems (MEMS), computer vision, fibre optics and advanced data interpretation techniques may revolutionise structural health monitoring (SHM). Dedicated SHM of bridge assets has the potential to produce valuable data-sets and provide owners and managers with information to aid with key questions such as: current performance, margins of safety, actual loading, stress history and risk of fatigue, extent of deterioration and residual life. However, the parameters measured and value of the data obtained will differ when viewed from the perspectives of different stakeholders such as asset owners, designers, contractors and researchers. In this paper the purposes of monitoring are reviewed. A methodology is proposed to facilitate formal discussions between the key stakeholders before any deployment is specified and to ensure that scarce resources are not wasted in the pursuit of data as opposed to information...
