Embodiment 1

[0031] see figure 1 , the method described in this embodiment is based on the device. The two pressure sensors on the left and right sides collect the pressure data of the body held on the left and right sides of the mobile terminal to identify whether the mobile terminal is out of the user's hand; the light sensor collects the pressure data on the front and back of the mobile terminal. Light data, through the light data difference between the front and back to identify whether the mobile terminal is on the front or the back when it falls; the two distance sensors on the front and back are used to collect the distance data of the mobile terminal from the ground when it falls, when the mobile terminal leaves the human body or the desktop When falling, the distance sensor measures the height and distance data from the ground in real time. When the height distance is close to the dangerous distance value, the controller controls the drive circuit to drive the anti-drop device to w...

Abstract

The invention discloses a mobile terminal fall-off identification method comprising the following steps: determining whether a present mobile terminal has left a hand or not according to pressure sensor data on the left and right sides of the mobile terminal; if not, determining whether the present mobile terminal may fall or not according to the light sensor data from the front and back surfaces of the mobile terminal; if yes, determining whether the falling acceleration speed of the present mobile terminal is similar to or equal to the gravitational acceleration speed or not according to the distance sensor data from the front and back surfaces of the mobile terminal; if yes, determining the present mobile terminal is in a falling state. The method can accurately identify whether the present mobile terminal is in the falling state or not, thus providing accurate signals for opening an anti-falling device, allowing the falling mobile terminal to safely land, preventing the mobile terminal from being damaged, and increasing the service life.

Description

technical field [0001] The invention relates to the field of mobile terminal safety protection research, in particular to a method for identifying the fall of a mobile terminal. Background technique [0002] With the rapid development of society, mobile terminals (including mobile phones, tablet computers, etc.) have become an indispensable tool in our daily life, and its development makes our life more convenient. But at the same time, mobile terminal users have been plagued by a real problem, that is, mobile terminals often fall due to carelessness. Once they fall from a high place to the ground, they will cause a certain degree of damage. Most of them are broken screens and shells. Cracks, and some internal circuits will be loose or damaged, resulting in malfunction. [0003] In order to prevent damage caused by falling mobile terminals, R&D personnel have conducted various researches on hardware and software, and one of the core points is how to accurately identify whet...
