Inovação tecnológica e sua aplicabilidade em sistemas de alertas sonoros eletrônicos para evacuação em massa

Abstract

With the growing number of hydroelectric plants located near habitable areas, there was a need to mitigate the risks and their factors, which can trigger dam ruptures, putting the population in danger near the areas in the face of a possible dam rupture, so in this perspective, sound alert systems have contributed to the protection of the population in risk zones near hydroelectric and mining plants, in order to save and protect the lives of residents, by triggering high-powered acoustic sirens to evacuate the population in advance in emergency situations of dam failure. Based on this preliminary information, this study aimed to evaluate the implementation of a high-power sound warning system developed for emergency notification of mass population evacuation of residents near dams of the Rio do Peixe Power Plant. To this end, after the construction of the theoretical framework, focused on technological innovation, intellectual production, specificities of a sound alert system, material and operational parameters were established to analyze and study the TELEVALE emergency notification system (SNE-T), idealized and designed by the researcher, with wireless radio frequency siren activation, and use of solar panels to provide electrical energy. In the field research, initially the Rio do Peixe Plant sent data in the form of previous mapping of the Self-Rescue Zone (ZAS). Subsequently, the Remote Alert Stations were installed at strategic points defined by the plant, followed by the open field simulations to validate the sound pressure level of at least 70 dB, and also to collect data and information aligned with the objectives of this study. The results indicate that the SNE-T is effective, safe and reliable, considering that all measurements performed were above 70 dB, meeting the requirements of the National Dam Safety Policy. It is important to report that due to the success of the SNE-T, the researcher and TELEVALE were awarded, in 2022, by the National Innovation Award, referenced, for the technical, acoustic and technological aspects, as well as for the low cost of production and implementation, since the SNE-T is 100% national development. It is inferred that the innovative technology of the emergency alert system, analyzed in this research, is reliable, effective and safe, in addition to being financially viable.
