Geotechnical Monitoring System Related to Hillsides in Real Time
landslides slopes; sensing, MEMS technologies, and monitoring.
Understanding the geokinetic behavior of mass movements in landslides is of vital importance as a way of preventing and mitigating human and environmental damage. In this study, the development of a Real Time Hillside Geotechnical Monitoring System (SMGRETR), model was implemented in an urban area susceptible to landslides, within the Metropolitan Region of Recife-PE, Brazil. For this, a set of geotechnical and pluviometric measurement equipment using instruments such as: inclinometer, pluviometer, soil moisture content measurement sensors (magnetometry and electromagnetic wave emission), were integrated with electronic devices and analysis methods, in order to guarantee the functionality and automation of the systems, as described below: 1) software (server) with processing and storage in clouds and hardware based on the concepts of internet of things - IOT; 2) Communication technologies – LoRa, GPRS/GSM and GPS/GNSS; 3) Microelectromechanical system – MEMS; 4) a system for processing and storing data in clouds (SPAN), which receives information (data) from its respective sensors and the Pernambuco Water and Climate Agency – APAC; 5) Energy management system with the respective energy modules (photovoltaic plate). In addition, as a methodological strategy, an automated system for measuring soil moisture content was developed using a microwave oven to allow calibration and measurement of the system's moisture content sensors. The experimental results demonstrate that the proposed model can provide accurate information on geotechnical aspects with a greater breadth of analysis, establishing a comprehensive method for the investigation and monitoring of slopes. On the other hand, even due to the reduction of operational costs and materials used in this project, the system can offer an affordable and reliable strategy compared to other system models on the market.
