In Peru, there are many monuments of high cultural and historical value, and with this, a rising need to ensure their conservation and optimal preservation over the years. Future structural damage situations can be avoided, and better restoration plans can be proposed by using non-invasive diagnostic techniques. This requires a constant process of monitoring to evaluate their structural state over time. For this purpose, a remote monitoring visualizing tool was proposed by using simple and reliable off the shelf applications. By establishing this system, it is now possible to visualize real time data from different projects, enabling the access to this data from any electronic device with internet connection through the web platform. The paper shows a detail description of the developed tool based on the following stages: (i) Acquisition and centralization of acceleration data, (ii) Wireless transfer/reception and processing of acquired data in a base station; and (iii) Dynamic visualization of processed data through a web platform. Accelerometers, data acquisition system, data processing software (LabVIEW), file transferring software (Bitvise and OneDrive), as well as web server services (Amazon Web Server) were used to acquire, transmit, process and visualize the changes in acceleration. The developed tool is use to monitor the “Church of San Juan Bautista de Huaro”. In this case study, the tool presents real time information about modal frequencies, damping, maximum accelerations, and maximum RMS, which are relevant to understand the current “health” of the structure. |
