Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0042] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for controlling a physical button of the present invention, which may specifically include the following steps:

[0043] Step 101, emitting infrared light;

[0044] In the embodiment of the present invention, firstly, an infrared light emitting module may be used to emit infrared light, and the infrared light may be linear infrared light. The infrared light emitting module has a point infrared light emitter and a grating, and the point infrared light emitted by the point infrared light emitter is refracted through the grating to form a linear infrared light. The emission port of the infrared light emitting module is parallel to the pla...

Abstract

The embodiment of the invention provides a method and device for controlling physical keys. In the embodiment, infrared light is emitted, when the infrared light is reflected to generate reflection light spots, coordinate information of the reflection light spots is obtained, key numbers are determined by adopting the coordinate information, and the physical keys corresponding to the key numbers are controlled, so that non-contact control over the keys is achieved, bacteria and viruses are prevented from being reserved and propagated, and meanwhile, the physical keys do not need to be replaced, so that the hardware cost is greatly reduced while the mounting efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of button control, in particular to a method and device for controlling a physical button. Background technique [0002] With the continuous outbreak of the new coronavirus pneumonia, public health issues have been paid more and more attention, and contactless key technology has also been promoted and applied. Contactless button technology, that is, a technology that can control the state of a button without touching the physical button. After the keys of the elevator are touched and pressed by many people, some bacteria or viruses may survive on the surface of the keys. By clicking the keys in a non-contact way, there is no need to touch the surface of the keys, which can prevent bacteria and viruses from infecting other users. [0003] At present, the non-contact button solution in the elevator industry is mainly to replace the elevator buttons with non-contact function. The elevator buttons are m...
