However, when the user tilts the electronic device to a certain angle, the proximity sensor also tilts accordingly, so even if there is someone in front of the electronic device, the distance sensor may not be able to detect it, causing the system to enter sleep mode, which not only wastes the user's time, waste of resources

Embodiment approach
[0017] After receiving the angle value sent by the inclination sensing unit 300, the processing unit 100 determines the angle value θ of the electronic device 10 relative to the vertical direction, and compares it with a predetermined angle value, and if the angle value θ does not exceed the predetermined value angle value, the control power management unit 500 distributes a voltage for the distance sensing unit 400, thereby turning on the distance sensing unit 400, and when the angle value θ exceeds the predetermined angle value, the control power management unit 500 does not provide voltage for the distance sensing unit 400. The sensing unit 400 distributes a voltage, thereby turning off the distance sensing unit 400 . The predetermined angle value can be preset and stored in the memory 700 by the system, or can be set by the user through the input unit 800 . In a preferred implementation manner, the predetermined angle value may be 45 degrees. In other embodiments of the p...

The invention provides an electronic device with a mode switching function and a control method thereof. The electronic device comprises a distance sensing unit, a processing unit and an inclination sensing unit, wherein the distance sensing unit is used for sensing whether someone exists in a certain range or not; the processing unit controls the electronic device to enter a sleep mode when the distance sensing unit senses that nobody exists in the certain range; the inclination sensing unit is used for periodically sensing angles of the electronic device relative to X, Y and Z axes and sending obtained angle values to the processing unit; the processing unit compares the received angle values sent by the inclination sensing unit with a preset angle value, switches on the distance sensing unit when the angle values do not exceed the preset angle value and switches off the distance sensing unit when the angle values exceed the preset angle value. According to the electronic device and the control method thereof, when the electronic device inclines to a certain angle, the distance sensing unit is switched off, so that resources are saved.
Description
technical field [0001] The invention relates to an electronic device and its control method, in particular to an electronic device with mode conversion function and its control method. Background technique [0002] In order to save energy, the existing electronic devices generally have the function of switching between normal working mode and sleep mode. A common practice is to install a distance sensor on the electronic device. When the distance sensor detects a person within a certain range, the electronic device is controlled to enter the normal working mode. When present, the control electronics go into sleep mode. However, when the user tilts the electronic device to a certain angle, the proximity sensor also tilts accordingly, so even if there is someone in front of the electronic device, the distance sensor may not be able to detect it, causing the system to enter sleep mode, which not only wastes the user's Time and resources are wasted.
