Non-contact induction elevator button and control method

Abstract

The invention provides a non-contact induction elevator button and a control method. The non-contact induction elevator button comprises a button body, wherein the outer surface of the button body isprovided with a transmitting device, a receiving device and a prompting device, the transmitting device comprises an infrared transmitting tube, the receiving device comprises an infrared receiving tube and an infrared sensor, the prompting device comprises an acousto-optic prompter, the bottom of a button fixing plate is provided with an operation box, and a microprocessor and a power supply arearranged in the operation box. According to the button and the method, the infrared receiving tube receives infrared light beams shielded by the human body and sends a received first signal to the microprocessor, the infrared sensor receives infrared light radiated by the human body and sends a received second signal to the microprocessor, when the microprocessor detects the first signal and the second signal at the same time, the microprocessor sends the signals to a control cabinet, the control cabinet drives an elevator to operate, and double signal superposition control prevents elevator operation system disorder caused by accidental touch of other articles and prevents human body illness caused by cross infection due to direct contact between the human body and the button.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and in particular relates to a non-contact induction elevator button and a control method. Background technique [0002] In the long river of history, various infectious and parasitic diseases have been prevalent in different periods and regions, and have seriously threatened the survival and development of human beings. Even today, although great achievements have been made in the fight against infectious and parasitic diseases, some new problems have emerged. For medical workers engaged in infectious diseases and infectious diseases, they face huge challenges. [0003] At the beginning of 2020, the novel coronavirus pneumonia epidemic is raging all over the world. Due to the complex transmission routes, including but not limited to air transmission, aerosol transmission, droplet transmission, fecal-oral transmission and other ways. Therefore, people should take isolation and pro...

Problems solved by technology

[0005] In order to prevent the human body from directly touching the elevator buttons, some passengers press the buttons with toothpicks or paper towels to avoid cross-infection, but toothpicks or paper towels are for one-time use, which is a serious waste, not energy-saving, not environmentally friendly, and the cleanliness of the items cannot be guaranteed , easy to cause infection through items
