Core technical advantages: First, dual disinfection technology, UV-C ultraviolet destroys the DNA/RNA structure of microorganisms, low-temperature plasma decomposes harmful microorganisms and odor molecules, dual effects realize full-space disinfection, sterilization rate 99.99%, can effectively kill COVID-19, influenza virus, Escherichia coli, Staphylococcus aureus, etc.; Second, intelligent human body induction, adopting millimeter wave radar + infrared dual induction, recognizing personnel entry within 0.5 seconds, immediately stopping ultraviolet disinfection to avoid human exposure and ensure riding safety; Third, full-time control, two modes of timed disinfection and induction disinfection can be set. Plasma continuous disinfection is used during peak hours, and UV-C deep disinfection is used during low peak hours to achieve 24-hour protection; Fourth, safety and environmental protection, no chemical agents, no ozone residue, no secondary pollution, no noise during disinfection, and no impact on the normal use of the elevator; Fifth, IoT management, the system is connected to the elevator IoT platform, which can remotely monitor the disinfection status, equipment failure, consumable life, automatically push maintenance reminders, and realize remote operation and maintenance. At present, the system has been installed and applied in more than 300,000 elevators in public places such as hospitals, shopping malls, schools, and subways nationwide.
