Password input panel and control method thereof

Abstract

The invention discloses a password input panel and a control method thereof. The password input panel comprises a panel body, a control chip, and a light unit, an input detecting device and a brightness detecting device respectively electrically connected with the control chip. The panel body comprises a password input area which inputs a password, the light unit is disposed on the periphery of the password input area, and the input detecting device is connected to the panel body. When the panel body is operated, the input detecting device generates a detection signal, and transmits the detection signal to the control chip. The brightness detecting device is controlled by the control chip, to detect ambient brightness information around the panel body. The control chip is used to activatethe brightness detecting device to detect ambient brightness information when receiving the detection signal, and adjust brightness of the light unit according to the ambient brightness information. The password input panel automatically adjusts panel light according to the ambient brightness, bringing about more intelligent use experience and effectively reducing power consumption.

Description

technical field [0001] The invention relates to the technical field of intelligent door locks, in particular to a password input panel and a control method thereof. Background technique [0002] In the related prior art, the environment and human body are detected by the environment brightness sensor and the human body sensor, and the backlight brightness of the screen is adaptively adjusted according to the current environment brightness value when the user is operating, so that the user can see the screen display more clearly. Content; if the current ambient brightness value is small, the controller will automatically reduce the brightness of the backlight of the screen so that the user does not feel glare. When no one is operating, the controller will reduce the brightness of the screen to achieve the effect of energy saving and emission reduction. However, the human body sensor is easily affected by the environment, temperature, etc., resulting in inaccurate brightness ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the human body sensor in the prior art is easily affected by the environment, temperature, etc., resulting in inaccurate brightness adjustment; people and animals passing by unintentionally will also cause the human body sensor to misoperate; When no one is operating, only reducing the brightness of the screen, there are still problems such as waste of energy, a password input panel and its control method are provided
