Terminal electromagnetic radiation detection method, apparatus and terminal

Abstract

The embodiments of the invention disclose a terminal electromagnetic radiation detection method, apparatus and terminal. The method herein uses a capacitive touch screen which is disposed in a terminal to set a non-shielding region for sensing terminal electromagnetic radiation on the basis of the fact that electromagnetic wave often affects the capacitance of a capacitor; then compares and analyzes capacitor detection values of the capacitive touch screen, and if the capacitor detection value is smaller than a touch operation threshold value, which means the capacitor detection value meets preset conditions for an early warning of terminal electromagnetic radiation, then a corresponding early warning alert operation is executed so as to alert a user to use the terminal properly. According to the embodiments of the invention, by innovating current capacitive touch screens, the method herein can directly detect electromagnetic radiation of the current terminal and the actual electromagnetic radiation of the ambient environment on the current terminal, and can increase the accuracy in detecting terminal radiation; and based on the corresponding relation between the detected capacitance and the safe threshold of preset electromagnetic radiation amount, fast implements early warning operation, obviates the need for complex data calculation, and can ensure in-timeness of radiation early warning.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal electromagnetic radiation detection method, device and terminal. Background technique [0002] With the development of technology, the use of mobile terminals such as mobile phones and smart watches is becoming more and more popular. When a user uses a mobile terminal, radio waves are transmitted between the mobile terminal and the cellular base station, and these radio waves are called terminal electromagnetic radiation. [0003] The electromagnetic waves radiated by the above terminals not only affect the health of the human body, but also affect the normal operation of the electronic devices inside the mobile terminal. For example, when the radiation intensity of the terminal is too high, it may cause misoperation of the capacitive touch screen of the terminal. For this reason, the capacitive touch screen in the existing terminal is usually provided ...
