Design of Structural Health Monitoring Using Wireless Sensor Network Case Study Pasupati Bridge

Abstract

Structural health monitoring (SHM) of civil infrastructure using wireless sensor networks (WSNs) has received significant public attention in recent years. The benefits of WSNs are that they are low-cost, easy to install, and provide effective data management via on-board computation. This paper reports on the designing SHM using WSN on the Pasupati Bridge a cable-stayed bridge in Bandung with a construction 303-m long bridge across the valley , including a cable stayed bridge along 161-m. The design central components of the WSN that will be proposed are the Imote2 smart sensor platforms, a custom-designed sensor boards, and gateway. In total, 42 sensor nodes and one gateway will be proposed to monitor the bridge using autonomous SHM application with vibration triggering the system to initiate monitoring.

Applying Sensor-Based Technology to Improve Construction Safety Management

“…For example, temperature sensors embedded in concrete can record the concrete hardening process in an early phase, which has been used to evaluate the quality, compressive strength and flatness of concrete [ 64 ]; optical fiber sensors embedded in concrete have been applied to monitor the strain and cracks of structures [ 65 ]. In recent years, WSN has been widely utilized in structural health monitoring of bridges [ 66 , 67 , 68 , 69 , 70 , 71 ], dams [ 72 , 73 ] and other important infrastructures concerning people’s life. For example, Shen et al [ 74 ] developed a WSN for structural health monitoring of China National Stadium (Bird’s Nest).…”

Wireless Sensor Placement Optimization for Bridge Health Monitoring: A Critical Review

“…In addition to acceleration sensors, strain sensors, magnetic sensors, ultrasonic sensors, piezoelectric sensors, and specialized WSNs integrated with GPS are employed in bridge projects owing to their respective advantages [3,9,10]. Regarding wireless sensor hardware, current research endeavors focus on enhancing measurement accuracy [7,11], reducing node energy consumption [12], lowering sensor costs [1,10], and minimizing sensor dimensions [13].…”

“…Strategies to enhance efficiency include employing wireless sensor nodes with a high sampling rate or configuring nodes within a topological network, thereby augmenting both data collection speed and coverage area [7,16]. Moreover, enhancing data storage primarily involves hardware improvements, such as increasing the memory capacity of nodes to extend storage capabilities and monitoring durations [1,12], and streamlining transmission post-acquisition to alleviate data congestion [7]. Mitigating power consumption relies on employing low power, low-duty cycle transmission protocols like ZigBee [11,12], or implementing specific acquisition and transmission schedules to keep nodes in a low-current dormant state when not in operation [8].…”

“…Furthermore, digital filtering and secure copy protocols significantly enhance data security and quality, facilitating robust node-to-node communication [13,15]. Topological network architectures and multi-hop communication protocols enable long distance data transmission across extensive bridge spans through the extensive deployment of wireless sensor nodes [12,14]. This approach is further augmented by utilizing specialized radio communication bands [8].…”
