Abstract
Present-day technologies used in SHM (Structural Health Monitoring) systems in many implementations are based on wireless sensor networks (WSN). In the context of the continuous development of these systems, the costs of the elements that form the monitoring system are decreasing. In this situation, the challenge is to select the optimal number of sensors and the network architecture, depending on the wireless system’s other parameters and requirements. It is a challenging task for WSN to provide scalability to cover a large area, fault tolerance, transmission reliability, and energy efficiency when no events are detected. In this article, fundamental issues concerning wireless communication in structural health monitoring systems (SHM) in the context of non-destructive testing sensors (NDT) were presented. Wireless technology developments in several crucial areas were also presented, and these include engineering facilities such as aviation and wind turbine systems as well as bridges and associated engineering facilities.
Highlights
The implementation and development of wireless communication for unlocking the potential of structural health monitoring (SHM) systems in aerospace, bridge structures, and wind turbines seems to be an essential and most urgent research problem as well as a technical one
The aerospace industry ought to consider the substitution of some aerial-vehicle sensor wiring with wireless communications; the related sensors are known as aerospace wireless sensors (AWSs)
Wireless sensor networks which have the advantages of reducing the costs concerning the implementation of SHM systems and enhancing data processing efficiency have become an attractive option for traditional tethered sensor systems
Summary
The implementation and development of wireless communication for unlocking the potential of SHM systems in aerospace, bridge structures, and wind turbines seems to be an essential and most urgent research problem as well as a technical one. Wireless sensor networks (known as WSNs) which have the advantages of reducing the costs concerning the implementation of SHM systems and enhancing data processing efficiency have become an attractive option for traditional tethered sensor systems. Wireless technologies have been considered in terms of their applicability in WSN (Wireless Sensor Networks), SHM (Structural Health Monitoring), and communication of the main subsystems in aircraft—ASN (Avionics Sensor Network) and WAN (Wireless Avionics Network). The possibility of remote, wireless access to information on the current state of the structure allows cost savings related to inspections and periodic reviews. Still, above all, it increases the safety of the structure and its users. Examples of applications in this type of construction are presented in a further chapter of the paper
