Description

Elevator non-contact virtual button operation method

Technical Field

The invention relates to the technical field of application of elevator buttons, in particular to a contactless virtual button operation method for an elevator.

Background

In recent years, due to rapid development and application of computer vision technology, various industries apply the technology to practical application. The elevator trade is usually through push type entity button to come to select the floor that the elevator will arrive, along with the continuous progress of science and technology, people have had new requirement to quality of life, and elevator manufacturer replaces the virtual button of touch-sensitive screen with original push type entity button, has promoted the happiness of taking the elevator personnel greatly. The outbreak of new crown epidemic situation makes elevator contact button become the main route that virus spread produced cross infection. The traditional elevator key can not disinfect everyone in time after operation, and can not meet the epidemic prevention requirement of eliminating viruses in time.

Chinese patent No. CN211781218U discloses a lighter for epidemic prevention, which uses a lighter to replace a hand to operate a button in an elevator during epidemic situation, and the method adds a U-shaped metal rod at a fire outlet of the lighter, and uses the U-shaped metal rod to replace a finger to press the button, so that after the button of the elevator is pressed, the lighter is ignited, and the U-shaped metal rod is disinfected by high temperature. However, the method is inconvenient, the lighter needs to be carried with the elevator matched with the entity button all the time, and the lighter is small in size and easy to lose, so that complete elimination of viruses and bacteria cannot be guaranteed; for the elevator matched with the touch screen virtual buttons, the touch screen is easily abraded and even damaged due to the metal surface of the elevator.
