Summary

Mining industry plays an important role for economy, yet it is characterized as an extremely dangerous industry, with a high accident rate, endangering the health and safety of workers. Today's security systems are unable to meet the need for real-time risk detection. The subject of this thesis is the design, implementation and programming of an original biometric vest with built-in sensors (Biometric Search & Rescue Vest). The main features of the biometric vest are its capabilities for continuous and real-time monitoring of user’s biometric data, the immediate notification of the information control center when the recorded value exceeds predefined threshold, as well as its low cost. It has the ability to collect and transmit data to mobile devices with a user-friendly interface, or, to a server, enabling the creation of the user's biometric profile, as well as, save the data for further study. In addition, it collects and monitors environmental indicators related to safe work while simultaneously combining and transmitting multi-user data, giving the ability of mapping the working conditions of the wider area. Specifically, with built-in sensors, it provides real-time measurement of the user's heart rate, temperature, exact location, as well as the presence of hazardous chemicals, such as carbon dioxide, carbon monoxide, LPG and other harmful chemicals in the environment. Vest’s sensors have also the ability of detecting a possible fall, while the operation time of the prototype is estimated at 15 hours.During the dissertation, the evaluation of the biometric vest was carried out in a quarry in the area of Rethymno where hazardous working conditions prevail, with frequent exposure to harmful chemicals and dust. Therefore, an important part of the study is the collection and processing of data on occupational safety hazards during quarrying, and the combination of biometric vests with the simultaneous use of unmanned aerial vehicles, offering plenty of opportunities in transportation of medical equipment or medicines in an emergency situation. The biometric vest can be used in a variety of industries, such as oil rigs, mineral quarries, and mines. More generally, the idea of the biometric vest is based on the effort to create a personal guard for citizens of all ages protecting them from both working and environmental, as well as, daily hazards, especially for sensitive groups of citizens with health problems.
