TWM555496U - An automatic screen switching system with infrared detection shielding - Google Patents

Abstract

The invention relates to an automatic switching system for a shielding sensing screen, which includes an infrared transmitting unit, an infrared receiving unit, a person sensing unit and an automatic screen switching unit. The infrared emitting unit is disposed at a preset position in front of the front of the screen and is opposite to the front of the screen to emit infrared light to the front of the screen. The infrared receiving unit is disposed outside the screen and opposite to the front of the infrared emitting unit. To receive infrared rays emitted by the infrared emitting unit; the human sensing unit is electrically connected to the infrared emitting unit and the infrared receiving unit to sense whether a person is in a preset position in front of the screen and send a person Sensing signal; the screen automatic switch unit is electrically connected with the human sensing unit to receive the human sensing signal and switch the power switch of the screen according to the human sensing signal. Therefore, a masked sensing screen automatic switch system that can effectively save energy and improve convenience is formed.

Description

Screen-sensing screen automatic switch system

This creation relates to an automatic switch system of a cover-sensing screen, especially an automatic switch system of a cover-sensing screen that can determine whether an operator is in place. The human sensing unit and related components can be used to detect whether the operator It is located in a preset position in front of the screen, and the power switch of the screen is turned on and off according to the sensing result, which can effectively save energy and improve convenience.

Press to learn how to use the computer screen to turn on and off. Most of the time, you can manually move the mouse to turn on the hibernation screen, or manually turn on and off the screen's power switch.

However, the manual movement of the mouse to turn on the hibernation screen appears redundant when the screen display content does not need to be changed; the manual power switch of the screen's power switch is particularly labor-intensive and does not meet the convenience of modern life Sexual needs.

In view of the lack of convenience derived from the conventional computer screen switching method, the present invention provides an automatic screen switch system for shielding and sensing, which includes an infrared transmitting unit, an infrared receiving unit, a person sensing unit, and an automatic screen switching unit.

This creation provides an automatic switch system for the screen of the sensing type Obstacle reflection detects the distance of obstacles. It detects whether a person is in a preset position in front of a screen and turns on or off the power switch of the screen according to the detection result.

FIG. 1 is a schematic diagram of the electrical connection of the units in one embodiment of the present invention.

Please refer to FIG. 1. This creative system provides an automatic switching system for a cover sensing screen. The automatic switching system for a cover sensing screen includes an infrared transmitting unit 10, an infrared receiving unit 11, a person sensing unit 12 and an Screen automatic switch unit 13. The infrared emitting unit 10 is disposed at a preset position in front of the front of the screen and is opposite to the front of the screen to emit infrared light to the front of the screen. The infrared receiving unit 11 is disposed outside the screen and front of the infrared emitting unit 10 In contrast, it is used to receive infrared rays emitted by the infrared emitting unit 10; the human sensing unit 12 is electrically connected to the infrared emitting unit 10 and the infrared receiving unit 11 to sense whether a person is located in front of the screen in front of the screen. Set the position and send a person sensing signal; the screen automatic switch unit 13 is electrically connected to the person sensing unit 12 to receive the person sensing signal and switch the power switch of the screen according to the person sensing signal .

The above description is a specific description of one of the feasible embodiments of this creation, but this embodiment is not intended to limit the scope of patents of this creation.
