The traditional elevator product is single, and the human elevator interaction method is unchanged. Since the new crown epidemic has been rampant, people are prone to virus infection when they press the button in the elevator. The intelligent and contact-free elevator can effectively stop the virus infection. Raspberry Pi, which uses Linux as its core architecture, has developed a :“contact-free” elevator control system through the use of artificial intelligence, big data, Internet of Things and other fields. The traditional physical buttons that require manual clicking are replaced with voice control, face retrieval, voice synthesis, and NFC near field communication, creating a variety of new elevator control solutions. The necessary information is displayed in real time via OLED, and can then be monitored or commanded from a desktop or mobile terminal. It has operating software for web, iOS and Android. Tests have shown that the Contactless intelligent elevator system is functional and stable in operation, building a life-safety line of defense for people in communities, public places, hospitals, etc.
