Problems solved by technology

However, when the mobile terminal is blocked by external equipment, it will affect the detection of the SAR sensor, and the SAR sensor will cause misadjustment of the transmission power. For example, when the mobile terminal is connected to an extension device, the SAR sensor may mistakenly believe that the human body is approaching The mobile terminal then reduces the transmission power when it should not be reduced, which affects the user experience

Abstract

The invention discloses a control method and electronic equipment. The method comprises: detecting whether the electronic equipment is connected with an extension device, wherein the extension devicecan be detachably connected with the electronic device, and the extension device is used for enhancing a function of the electronic equipment; determining a response policy to an SAR (Synthetic Aperture Radar) sensor of the electronic equipment based on the detection result that the electronic equipment is connected with the extension device; and responding to sensing information detected by the SAR sensor when the electronic equipment is connected with the extension device based on the response policy.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic wave absorption ratio (SAR, Specific Absorption Rate), in particular to a control method and electronic equipment suitable for SAR sensors. Background technique [0002] Mobile terminals, such as mobile phones and tablet computers, are favored by users because of their portability. There are generally SAR sensors in mobile terminals, which can detect capacitance changes in a certain area, so that when the human body is close to the mobile terminal, the transmission power of the mobile terminal can be reduced to avoid damage to the human body caused by high transmission power. [0003] The SAR sensor triggers the electronic device to reduce the transmission power based on the SAR threshold. The SAR sensor compares the detected data with the SAR threshold. When the data detected by the SAR sensor is less than or equal to the SAR threshold, it means that the human body is very close t...
