Embodiment Construction

[0031] figure 1 It is a schematic diagram of a device for avoiding accidental touch of a power switch according to an embodiment of the present invention. Please refer to figure 1 , the connection relationship and usage of each component in this embodiment will be described below. The device 101 for avoiding accidental touch of the power switch is applicable to the electronic device 100 and includes a three-dimensional sensing unit 102 and a control chip unit 103 . The 3D sensing unit 102 continuously detects the position change of the electronic device 100 to generate 3D data when the system power is turned off. Among them, the three-dimensional sensing unit 102 can detect the change of the gravitational acceleration of the electronic device 100 in the three-dimensional space on the X-axis, Y-axis, and Z-axis to establish three-dimensional acceleration information, so the three-dimensional sensing unit is placed at the center of gravity of the electronic device 100 The pos...

Abstract

The invention provides a method and device for avoiding the erroneous touch of a power switch. The device is used in an electronic device in order to avoid the startup of a power supply when the electronic device shakes intensively or is placed reversely. At first, when a system power supply is turned off, positional change of the electronic device is constantly detected in order to establish three-dimensional array data. Secondly, whether the power switch is enabled is detected in order to generate a system power supply turn-on signal. Finally, a tilt angle and a movement variable of the electronic device are calculated in accordance with the system power supply turn-on signal and the three-dimensional array data, in order to facilitate the judgment on whether the system power supply is turned up. If the tilt angle is within an angle interval and the movement variable is smaller than a movement threshold value, the system power supply is turned on. Otherwise, the system power supply is constantly turned off.

Description

technical field [0001] The present invention relates to a method and device for avoiding false touch of a power switch, and in particular to a method and device for avoiding false touch of a power switch by using a three-dimensional sensor (3D sensor). Background technique [0002] When a user is carrying an electronic product, he or she may accidentally touch the power switch of the electronic device to turn on the device, consuming excess power and easily causing internal hardware damage. In order to avoid accidentally touching the power switch, in the past, the power switch is placed under the upper cover of the foldable or slide-type electronic device or a sliding switch is used to reduce the probability of accidentally touching the power switch. But many portable electronic devices, such as all-in-one (All-In-One) computers, mobile phones, etc., still have the problem of false touches because there is no upper cover in the structure of such electronic devices. In the p...
