Controlling the source of infection, cutting off the transmission route, and protecting the susceptible population are the most important three measures in preventing infectious diseases. The new coronavirus has strong transmission performance, can survive in the air for a period of time, can be transmitted in the form of air aerosol and in the form of an attached object, and is very easy to infect parts such as the mouth, the nose and the eyes after the fingers contact. In life, particularly in high-rise buildings, the elevator is frequently used.

The elevator working state judgment logic is that 1: waiting for the person to use the elevator; 2: after the elevator reaches the target floor (the acceleration is changed, reversely changed and returned to 0), the door is opened and closed, whether the elevator is occupied or not is judged, and if the elevator is occupied, the process 2 is carried out again until no person enters the disinfection stage. The control logic of the disinfection equipment is that when the elevator is static, the door is closed and no person is in the situation, the working indicator lamp is turned on, the timer is turned on, the relay 11 is turned on so that the ultraviolet disinfection lamp 1 starts disinfection work, the timer, the working indicator lamp 8 and the relay 11 are turned off after the 10-second disinfection process is finished, the elevator enters the working logic again, and the next user is waited. In addition, in the disinfection process, the acceleration sensing module 5 and the infrared photoelectric sensor 4 poll the flag bit to check whether the elevator runs to other floors or the elevator door of the floor is opened, so that the ultraviolet disinfection lamp 1 is prevented from damaging the elevator user; at the same time, an emergency stop button 7 is provided to manually stop the disinfection process.
