Flexible smart sensor framework for autonomous structural health monitoring
Wireless smart sensors enable new approaches to improve structural health monitoring (SHM) practices through the use of distributed data processing. Such an approach is scalable to the large number of sensor nodes required for high-fidelity modal analysis and damage detection. While much of the technology associated with smart sensors has been available for nearly a decade, there have been limi...
متن کاملWireless Intelligent Sensor Network for Autonomous Structural Health Monitoring
Life cycle monitoring of civil infrastructure such as bridges and buildings is critical to the long-term operational cost and safety of aging structures. The widespread use of Structural Health Monitoring (SHM) systems is limited due to unavailability of specialized data acquisition equipment, high cost of generic equipment, and absence of fully automatic decision support systems. The goals of ...
متن کاملA Reconfigurable Wireless Sensor Network for Structural Health Monitoring
The paper presents a reconfigurable wireless sensor network for structural health monitoring. Real-time and periodic structural health monitoring can reduce the probability of collapse and the consequences of potential life-threatening conditions. The monitoring system is composed of two parts: the wireless network in which the sensor nodes are equipped with a 3axis accelerometer and a temperat...
متن کاملHardware-accelerated wireless sensor network for distributed Structural Health Monitoring
Civil infrastructure objects are subject to safety-related issues such as increasing loads and extended service live. Costly manual inspections of these structures should therefore be supplemented by automated continuous monitoring. In this work, a hardwareaccelerated wireless sensor network built entirely with energy-efficient embedded components is proposed as the basis for a distributed stru...
متن کاملSmart Sensing Technology for Structural Health Monitoring
“Smart” sensors with embedded microprocessors and wireless communication links have the potential to fundamentally change the way civil infrastructure systems are monitored, controlled, and maintained. Indeed, a 2002 National Research Council Report [1] noted that the use of networked systems of embedded computers and sensors throughout society could well dwarf all previous milestones in the in...
