Abstract

The invention relates to a device and method for adjusting radiation power and electronic equipment. The device comprises a first distance sensor, a processor and a modem, The first distance sensor isused for detecting whether a user is close to the first distance sensor; The processor is electrically connected with the first distance sensor and used for calculating the capacitance value variation of the capacitance of the first distance sensor according to the voltage of the first distance sensor; And the modem is electrically connected with the processor and is used for adjusting the radiation power of the wireless communication module according to the capacitance variation. According to the embodiment, the radiation power of the wireless communication module is adjusted through the capacitance value variation, so that the power consumption of the electronic equipment can be reduced, the influence of radiation signals on a user can be reduced, the problem of overlarge noise during optical detection in the prior art can be avoided, and the detection and control precision can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of electromagnetic compatibility, and in particular to a device and method for adjusting radiation power, and electronic equipment. Background technique [0002] With the development of communication technology, electronic devices such as smart phones or smart computers have become indispensable electronic devices in daily life. When using the electronic device, the electronic device needs to establish a communication link with a communication device (such as a base station, a router, etc.) to obtain data (such as a short message, a call, a video), and at this time, the electronic device has relatively large radiation power. For example, when a user makes a call with a smart phone, since the smart phone has established a communication link with the base station, the user is in a strong electromagnetic field at this time, which may affect the health of the user. [0003] In the related art, a distan...
