Description

Electronic device for monitoring the location of a protected person based on a sound signal and method of operation thereof The present invention relates to a technology for transmitting a sound source signal and analyzing it to accurately determine the location of a target. In particular, it can be usefully utilized in environments with many constraints, such as when communication is not smooth, and can be applied to various fields, such as determining the location of workers, the elderly, young children, and missing persons through the analysis of the sound source signal. Technology for accurately locating targets plays a crucial role in various industrial and security fields. For example, real-time tracking of workers' locations in industrial sites can ensure their safety in hazardous environments, while tracking the locations of vulnerable individuals requiring protection, such as the elderly or young children, can prevent accidents. However, conventional positioning technologies have often been implemented based on image analysis or through radar and lidar technologies; these methods have limitations, such as requiring expensive equipment and potentially losing accuracy under specific environmental conditions. For instance, positioning methods based on image analysis may suffer from reduced reliability and accuracy in environments with insufficient light or numerous obstacles, while radar and lidar technologies have the disadvantage of requiring expensive equipment and high maintenance costs, making commercialization difficult. In particular, these technologies are difficult to apply in environments with poor communication or enclosed spaces, and they have limitations in satisfying all the specific conditions of various industrial sites. To overcome these limitations, there is a need to develop technology capable of tracking targets with high accuracy in various environments at a low cost. This invention is a technology that determines the precise location of a target based on the analysis of sound source signals. Since sound waves can pass through walls or obstacles and can operate even in environments where communication connections are unreliable, this technology can be effectively utilized in various industrial and service sectors.
