Capacitive non-contact elevator button

Abstract

The invention discloses a capacitive non-contact elevator button which comprises a non-contact MCU, a power module, an induction antenna, a relay, an indicator lamp and a socket interface. The non-contact MCT is connected with the relay, the power module and the induction antenna. The relay, the indicator lamp and the power module are respectively connected with the socket interface. The aperture of the socket interface is 2.54 mm. A touch chip is arranged inside the non-contact MCU. The indicator lamp adopts an LED lamp. The capacitive non-contact elevator button is concaved in a button box by 14 mm, the non-touch function is started as long as a hand stretches into the button frame, so that when an elevator is crowded, the elevator button cannot be triggered mistakenly. A capacitive non-contact technology replaces a traditional mechanical button, and since the hand is not in direct contact with the elevator button, the service life of the elevator button is prolonged, and bacterial infection, which is caused by the fact that people are in contact with the surface of the elevator button, can be avoided.

Description

technical field [0001] The invention belongs to the technical field of non-contact buttons, and in particular relates to a capacitive non-contact elevator button. Background technique [0002] The traditional elevator buttons in the prior art usually use mechanical buttons, and the user needs to press the button to reach the floor with his hand to trigger the button. The traditional mechanical buttons in the prior art have the following defects: 1. Because the traditional elevator buttons in the prior art are mechanical buttons, each user needs to touch the surface of the button with his hand and press the button when using the elevator. As the number of times of use increases, the life of the elevator button will decrease. 2. When people touch the buttons, they may spread the bacteria on their hands to the surface of the elevator buttons, so that the bacteria can be easily transmitted to each other by hands. It will become an urgent demand for people to provide a capacitiv...
