Recently, Coronavirus disease (COVID-19) has been characterized as a pandemic, which is a serious threat to public health as well as the economy of the world. According to the medical authority’s statement, the COVID-19 mainly spreads through respiratory droplets and contact transmission. Besides, people in confined space, such as offices, cruise ships, classrooms, and workshops, are more likely to be infected through aerosol transmission. Hong Kong is a densely populated city. And there are so many confined spaces in high buildings. People in confined spaces are in danger nowadays. The current sterilization measure is spraying disinfectants manually. The concentration and volume of disinfectants are predefined, which cannot be changed during spraying. However, the concentration of bacteria and virus in confined space is always changing. Without environment monitoring and dynamic controlling system, we cannot complete comprehensive disinfection. A lower concentration or smaller volume will reduce the effect of disinfectants. A higher concentration or larger volume is a waste of resource, even damaging people’s health. This project aims to develop an intelligent monitoring and disinfecting system for the disinfection of confined space. With the help of artificial intelligence and cloud platform, the system can achieve dust particles’ monitoring, as well as temperature and humidity monitoring. When germs and viruses’ concentration is increasing, the system will conduct comprehensive sterlization using slightly acidic electrolyzed water with the help of the air-conditioning system. The new system is effective and easy-using. Besides, the cost of installing and upgrading is not very high. Therefore, the system could be widely used in confined spaces, such as offices and cruise ships.
