Method and system for utilizing distance sensing to reduce mobile phone radiation

Abstract

The invention discloses a method and system for utilizing distance sensing to reduce mobile phone radiation. The method includes the steps of S1, answering a mobile phone; S2, utilizing a distance sensor to detect the distance between a tested target and the mobile phone; S3, judging whether or not the distance between the target and the mobile phone satisfies a preset condition and obtaining a judgement result; S4, according to the judgement result, conducting corresponding adjustment on the radio frequency power of the mobile phone. The system includes a signal detection module, a comparisonmodule connected with the signal detection module and an adjustment module connected with the comparison module; the signal detection module detects the distance between the mobile phone and the cheek of a user; the comparison module compares the distance detected between the mobile phone and the cheek of the user by the signal detection module with a set distance to determine whether or not thedistance between the mobile phone and the cheek of the user is in accordance with the set distance, and obtains a judgement result; the adjustment module carries out corresponding adjustment on the radio frequency power of the mobile phone according to the judgement result. The method and system can be used for reducing the radio frequency power when it is detected that the cheek of the user approaches the mobile phone, the mobile phone radiation is decreased without adding SAR sensors and increasing the cost of hardware, and the practicability is high.

Description

technical field [0001] The invention relates to the field of reducing mobile phone radiation, in particular to a method and system for reducing mobile phone radiation by using distance sensing. Background technique [0002] When a cell phone is used to make a call, it emits radio waves (also known as radio frequency energy) that can be picked up by the nearest base station. Once the base station receives the radio waves from the mobile phone, it will be transmitted to the switching station, and the switching station will transfer the call to another base station or fixed telephone line network according to the type of the current call, so as to realize the call. This is the essence of mobile communication. Basic working principle. When people use mobile phones, the mobile phone will transmit radio waves to the base station, and any kind of radio waves will be more or less absorbed by the human body, thereby changing human tissues and possibly affecting human health. These r...
