Non-contact inductive switchgear and control method thereof

Abstract

The invention relates to a non-contact inductive switchgear and a control method thereof. The switchgear comprises an inductive information input unit, an electric device and a control unit, wherein the inductive information input unit can input hand induction information in a non-contact way and is provided with an inductive signal output end; the electric device can move under the action of electric excitation and is provided with a fixed end and a power output end; the fixed end is connected with the device body; the power output end is at least connected with an induction information input unit and can at least drive the induction information input unit or components therein to move; the control unit receives an induction signal for inducing the induction information input unit and generates the electric excitation which can drive the electric device to move; a signal input end of the control unit is connected with the signal output end of the induction information input unit; and an electric excitation output end of the control unit is connected with an electric excitation input end of the electric device. When the distance from the hand to the surface of an induction region of the induction information input unit reaches an effective induction trigger distance H, the surface of the induction region instantaneously moves for a distance of delta distance in the direction away from the hand so as to prevent the hand from touching the surface of the induction region.

Description

technical field [0001] The invention relates to a switch device, in particular to a non-contact induction switch device and a control method thereof. Background technique [0002] Mechanical key switches and push button switches are widely used in various known switch devices. Existing electronics, electrical equipment and electrical equipment such as elevator buttons and wall switch buttons belong to this type of switch device. These switchgears need to be touched by human hands and exert a certain force to realize the operation, which is very unhygienic, and the switchgears used by many people, especially in public places, are easy to spread viruses and bacteria. The spread of the SARA virus in 2003 has given us a warning, and the current spread of influenza A (H1N1) around the world makes people urgently need a non-contact inductive switch device. [0003] The disclosed non-contact induction switch device, such as CN 2619415Y non-contact / contact double-function elevator ...

AI Technical Summary

Problems solved by technology

The advantage of this type of non-contact induction switch device is that the non-contact induction operation can prevent the spread of viruses and bacteria, and has certain safety. The disadvantage of CN 2909701Y is that the light emitting component and the receiving component are very close to the button area, and the hands need to be slow and careful. If you are not careful, you will touch the surface of the button, and there is still a chance to contact the virus, which loses the meaning of non-contact operation

The disadvantage of CN2909701Y is that the light emitting component and the receiving component are far away from the button area, which can reduce the chance of touching the button area, but the deep sensing space sunken in the surface gives people a sense of insecurity, and the function characters on the button Difficult to see from certain angles, requires a lot of space

Setting luminous indications on the surface of the induction information unit and setting sound prompts in the switch may reduce this kind of false contact, but it cannot fundamentally solve it.
