Desenvolvimento e validação de sistema vestível para monitoramento de cães de busca e resgate

Abstract

The operational efficiency of cynotechnical teams in search and rescue missions is conditioned by communication effectiveness and the monitoring of canine behavioral patterns. However, remote supervision in scenarios of high structural complexity or dense vegetation still faces tactical and technological limitations. This study aimed to develop a monitoring system for search and rescue dogs, which comprised the engineering of a transmitter prototype based on a microcontroller, integrating an accelerometer, a gyroscope, and a sound detector. The system underwent an experimental protocol with dogs from the Search Dog Company (CBCães/CBMCE). Results showed that the fusion of kinematic and sound data enabled the identification of resting, displacement, and alert barking states with an overall accuracy of 98.70%. The LoRa protocol ensured the stability of real-time telemetric transmission with a reduced standard deviation (± 0.35), providing objective metrics for the handler's decision-making. In conclusion, the device demonstrates high technical and operational robustness, mitigating the subjectivity of human observation and optimizing assertiveness in victim localization in disaster scenarios.
