Optimal Sensor Placement And Damage Detection In Health Monitoring

Electronics and communication engineering

Abstract: Advanced engineering technologies are an emerging research area with multiple applications such as medical fields, home appliances, transportations, electrical systems, civil and mechanical systems, all manufacturing industry like chemical, fabrics, electronics equipment, structural like buildings, bridges, towers and so on, in our lives. It relies heavily on the pervasive civil infrastructure in which industrialized nations have huge investments. Malfunctioning of civil infrastructure has caused tremendous economic loss and claimed numerous human lives. To properly manage civil infrastructure, its condition or serviceability must be assessed and to be monitored. So nowadays, a sophisticated sensor usage in all fields is increased to monitor the condition of the structures. Hence continuous monitoring of structures is necessary and it is monitored by using Structural Health Monitoring (SHM) systems. Considering cost, reliable data, accuracy of results, and computation time into account the proper deployment of sensors becoming a challenging task in SHM. There are several methods for optimal sensor placement and in this study, ‘MSE’ technique has been introduced for the sensor placement. Genetic algorithm, an evolutionary algorithm belonging to the area of artificial intelligence is used for the optimization of the number of sensors.
