Contact-free elevator key control device

Abstract

The invention relates to the technical field of elevator control, in particular to a contact-free elevator key control device. The technical problems that an existing device is complex in operation, inconvenient to adjust and prone to generating germs are solved. In order to solve the technical problems, the contact-free elevator key control device is provided and consists of a main control mechanism, a trigger mechanism and a disinfection mechanism. By arrangement of a Raspberry Pi control module, an Arduino control module, a voice recognition module, an infrared photoelectric sensor, a pickup microphone, an electromagnet and a relay, a user can achieve key pressing without touching an elevator button with the hand during use, and therefore, the possibility of epidemic situation cross infection is avoided, the spreading risk is greatly reduced, and a safer elevator taking space is provided for passengers; and when the user cannot conveniently press the elevator button with the two hands, control over elevator floor keys can be achieved in a voice mode, and convenience and rapidness are greatly improved.

Description

technical field [0001] The invention relates to a contact-free elevator key control device, in particular to a contact-free elevator key control device, which belongs to the technical field of elevator control. Background technique [0002] The access to high-rise buildings depends on elevators, especially in office buildings, residential areas, shopping malls and other public places with dense traffic. At present, most elevators reach the desired floor by touching the floor buttons, and a large number of bacteria remain on the elevator buttons. In the current outbreak of the epidemic, facilities that are frequently touched by the public, such as door handles and elevator buttons in common places, may have the risk of cross-infection due to mutual contact, and the elevator is a confined space. During the special period of epidemic prevention and control, cling film, tissue paper and even toothpicks and ballpoint pens have become the standard equipment for prevention and con...

AI Technical Summary

Problems solved by technology

[0003] It is difficult to refit the existing elevator button control device in the elevator equipment. At the same time, it is necessary to take out the mobile phone to open the designated interface every time when taking the elevator, which will bring great inconvenience to the use, and also make the old people, children It is difficult for people such as other people to operate; the existing elevator button control device is usually unable to adjust, and cannot be applied to different elevator button spacing; the existing elevator button control device usually does not have a disinfection device, and people who have not used it are easy to go directly Touching the device, which can lead to cross-contamination
