Description

Classroom ultraviolet sterilizing system and its sterilizing control method

The invention relates to a disinfection and sterilization system, in particular to a classroom ultraviolet sterilization system and a corresponding sterilization control method. The classroom ultraviolet sterilization system can carry out targeted disinfection and sterilization on classrooms.

At the beginning of the Spring Festival in 2020, the sudden outbreak of new coronary pneumonia has made people pay more attention to environmental hygiene, and at the same time restricted people's normal living activities to a certain extent. For example, in order to prevent the spread of the novel coronavirus pneumonia epidemic in a large area, the opening time of various schools has been postponed again and again. Even if school starts as scheduled, schools need to pay more attention to disinfection and sterilization in classrooms than before.

As an important place for students to study and live on campus, classrooms have a certain number of students who gather for a long time every day. For example, about 40-60 students in each classroom in primary and secondary schools stay together for 6-8 hours every day, and for example, each classroom in a university campus has different students entering classes or self-study at regular intervals. The limited space in the classroom and the short-term gathering of people lead to more bacteria, which in turn increases the risk of spreading the source of infection. In order to provide students with an excellent learning and living environment, it is necessary to carry out more accurate and efficient disinfection and sterilization of classrooms.

For specific limited spaces such as classrooms where people often have intensive activities, in order to achieve good disinfection and sterilization effects, ultraviolet sterilization is the preferred method among existing disinfection and sterilization methods. When using ultraviolet sterilization to disinfect and sterilize classrooms, it is necessary to consider the possible damage caused by ultraviolet rays to the human body.
