Description

Multi-sensor and AI-based space sterilizer The present invention relates to a multi-sensor and AI-based space sterilizer, and more specifically, to a multi-sensor and AI-based space sterilizer capable of air purification, deodorization, and sterilization based on a photocatalyst, and capable of improving operational efficiency by predicting indoor air pollution by identifying the number of people and movements in places with a high volume of indoor traffic, such as government offices, and automatically adjusting the photocatalytic reaction intensity, natural light lamp intensity, and fan accordingly. This invention is a result carried out with support from the 'Eco-Startup Support Program' promoted by the Ministry of Environment and operated by the Korea Environmental Industry & Technology Institute. (Project No.: E1002025021304) Recently, as the atmospheric environment deteriorates due to factors such as fine dust, interest in personal health has increased, leading to the widespread use of air purifiers. Air purifiers operate by absorbing ambient air and then re-releasing it after it has been purified by filters. Generally, space sterilizers measure the indoor air quality only at the installation location within the indoor space and operate based on the measured air quality. However, in spaces with high foot traffic, such as government offices, pollution levels may be measured differently depending on the installation location or the size of the space; consequently, there is a possibility that the sterilizer may operate under conditions different from the actual air quality or fail to provide sufficient purification. Furthermore, due to the structure of the air purifier that involves the repetitive intake, purification, and exhaust of air during operation, there is a problem of low power efficiency relative to its purification capacity. Meanwhile, because government offices are frequented by many people, various odors, such as sweat and cosmetics, often mix together. Consequently, there is a high likelihood that various bacteria exist within the space. However, conventional air purifiers currently lack adequate measures to address this issue. Therefore, there is a need for a high-performance device capable of not only air purification but also deodorization and bacterial sterilization, as well as a system that can predict indoor air pollution by detecting the number of people entering and moving within the space without direct user operation, and operate automatically accordingly.
