Install the escalator disinfection device at the bottom of the handrail belt at the entrance of the escalator, isolated from the handrail area that passengers come into contact with, to prevent accidents where passengers' fingers could be caught in the escalator disinfection device. Combined with an intelligent control method, a corresponding timed sterilization and disinfection strategy is formulated based on the actual operation of the escalator, ensuring the hygiene of the escalator handrail belt and making passengers feel more reassured and safe when riding the escalator.
