System and method for achieving contactless control of existing button

Abstract

The invention provides a system and a method for realizing contactless control of an existing button. The system enabling an existing button to achieve non-contact control comprises a shell; and a device groove which is formed in the shell. According to the system and method for achieving non-contact control over the existing buttons, by arranging the non-contact control system, the non-contact control system is installed at the positions of the existing buttons in the using process, each button can be correspondingly provided with one system, each system is independently arranged, and therefore installation can be selected according to the actual using condition, the system cannot be limited by excessive existing buttons, and the system is more flexible to install; according to the system, the control mainboard, the non-contact sensor, the electromagnet, the elastic structure and other structures are mainly used for being arranged in a matched mode, during pressing, the non-contact sensor detects signals, and finally, the trigger block starts the button; non-contact control is achieved, pressing by means of an isolator is not needed, operation is easy, and the system is simple instructure and convenient to use; the trigger time is short, and the use is very convenient.

Description

technical field [0001] The invention relates to the field of non-contact control, in particular to a system and method for realizing non-contact control of existing buttons. Background technique [0002] The button is a commonly used control electrical component. It is often used to turn on or off the control circuit. The current is very small, so as to achieve the purpose of controlling the operation of the motor or other electrical equipment. The button is divided into: normally open button, switch A button with an open contact; a normally closed button, a button with a switch contact on; a normally open, normally closed button, a button with both on and off contacts; an action click button, a mouse click button; in general, The red button is used to stop a certain function, while the green button can start a certain function. The shape of the button is usually round or square. Most electronic products use buttons, the most basic human-machine interface tool. With the indu...

Problems solved by technology

[0005] The present invention provides a system and method for enabling the existing buttons to achieve non-contact control, which solves the problem that the existing elevators or other selective switches in other environments cannot achieve non-contact control well, and thus people can only rely on When pressing the button of the spacer, the operation is not convenient enough, and there is a risk of infection
