作为有效桥梁管理系统的一部分，传感器网络可以提供数据来支持检查和评估。无线传感器网络（WSNs）有可能提供显着的优势，传统的有线监测系统的传感器，布线，安装成本以及可扩展性。然而，无线传感器网络存在与功率、数据带宽和鲁棒性有关的缺点。为了评估潜在的无线传感器网络用于桥梁管理，一个网络的7个传感器节点安装在Ferriby路桥，一个三跨钢筋混凝土桥。三个位移传感器节点被放置在桥的拱腹上的裂缝上，以测量裂缝宽度的变化。三个倾角传感器节点安装在两个弹性轴承垫上，以测量轴承垫的倾角变化，而最后一个节点监测包含网关的盒子中的温度。无线传感器网络的安装进行了讨论，并从这个网络的数据进行了分析。最后，使用传感器网络，以支持检查和评估进行了讨论。
As part of an effective bridge management system, sensor networks can provide data to support both inspection and assessment. Wireless sensor networks (WSNs) have the potential to offer significant advantages over traditional wired monitoring systems in terms of sensor, cabling, and installation costs as well as expandability. However, there are drawbacks with WSNs relating to power, data bandwidth, and robustness. To evaluate the potential of WSNs for use in bridge management, a network of seven sensor nodes was installed on the Ferriby Road Bridge, a three-span reinforced concrete bridge. Three displacement transducer nodes were placed across cracks on the soffit of the bridge to measure the change in crack width. Three inclinometer sensor nodes were mounted on two of the elastomeric bearing pads to measure the change in inclination of the bearing pads while a final node monitored temperature in the box that contained the gateway. The installation of the WSN is discussed and data from this network is analyzed. Finally, the use of sensor networks to support inspection and assessment is discussed.
