Abstract
The historical buildings of a nation are the tangible signs of its history and culture. Their preservation deserves considerable attention, being of primary importance from a historical, cultural, and economic point of view. Having a scalable and reliable monitoring system plays an important role in the Structural Health Monitoring (SHM): therefore, this paper proposes an Internet of Things (IoT) architecture for a remote monitoring system that is able to integrate, through the Virtual Reality (VR) paradigm, the environmental and mechanical data acquired by a wireless sensor network set on three ancient buildings with the images and context information acquired by an Unmanned Aerial Vehicle UAV. Moreover, the information provided by the UAV allows to promptly inspect the critical structural damage, such as the patterns of cracks in the structural components of the building being monitored. Our approach opens new scenarios to support SHM activities, because an operator can interact with real-time data retrieved from a Wireless Sensor Network (WSN) by means of the VR environment.
Highlights
Cultural Heritage (CH) offers value and attractiveness to the cities and places of a nation
BEYOND NUMERICAL RESULTS From a technical point of view, the use of a Wireless Sensor Network (WSN) and of an Unmanned Aerial Vehicle (UAV) can be quite effective in acquiring a rich set of data to provide both experts and local authorities with a comprehensive description over time of the health of any ancient structure
The design of such a support system for decision making met the constraints of modularity, flexibility, and minimally invasiveness; its features allow to customize the installation and the monitoring process, respecting the peculiarities of the inspected architectural asset
Summary
Cultural Heritage (CH) offers value and attractiveness to the cities and places of a nation. Other remote techniques have been used in this context, further than UAVs. For instance, in [30], the authors survey the use of Global Navigation Satellite System (GNSS)-based technology, like multi-sensor and multi-constellation data acquisition techniques, to support monitoring activities for towers, buildings, and bridges. THE PROPOSED MONITORING SYSTEM AND THE THREE REAL CASE STUDIES The whole system is configured as shown in Figure 1: data collected by sensor nodes and by the UAV is sent to the remote server for data processing and storing. Several preliminary campaigns have been conducted to identify the most suitable placement locations for the sensor nodes in the monitored buildings, in order to: (i) install the minimum number of devices necessary to support SHM activities; (ii) limiting obtrusive installations; (iii) respecting enforced regulations on any placement on ancient surfaces (like walls). The sensors placement has been performed so to achieve minimal visual impact, while contemporary providing the desired detection of the structure modes
