Embodiment Construction

[0027] In some examples, please refer to figure 1 as shown, figure 1 It is a schematic diagram of a hand-held device falling freely according to an embodiment of the present invention, which includes a hand-held device 100 and a free-fall height H. Please also refer to image 3 , image 3 It is a schematic block diagram of a handheld device circuit according to an embodiment of the present invention. The handheld device 100 includes a central processing unit 101, a sensing unit 102, a drop control unit 103, a memory unit 104, a communication module 105, and a battery exchange unit 106 , a main battery 107 , a backup battery control unit 108 , and a backup battery 109 .

[0028] Wherein, the connection relationship of each component of the handheld device 100 is as follows: the central processing unit 101 is respectively coupled to the sensing unit 102 , the drop control unit 103 , the memory unit 104 and the communication module 105 . The drop control unit 103 is coupled t...

Abstract

The invention relates to a method for preventing data loss after free falling and a handheld device thereof, the method is used for the handheld device, and the method comprises the following steps: adetection step; a dormancy step; a switching step; a step of starting a flight mode; and a step of completing a sleep mode and a restarting step. In the detection step, when detected falling acceleration exceeds a critical value, a first trigger signal and a second trigger signal are generated. In the dormancy step, power supply of a main battery is stopped and a dormancy mode is executed according to the first trigger signal. In the switching step, a standby battery is started according to the second trigger signal. In the restarting step, after falling, impacting and standing, the standbybattery is switched back to the main battery.

Description

technical field [0001] The present invention relates to a method for preventing data loss and its handheld device, in particular to a method for preventing free-fall data loss and its handheld device, so as to avoid the loss of operating data when the handheld device falls or hits . Background technique [0002] Due to the advancement of technology, the existing handheld devices have become smaller and smaller in size and thinner in thickness. However, when the user is using the handheld device, it may accidentally drop or drop it. In other words, the falling impact may cause the battery to fall off, causing the handheld device to shut down due to a momentary power failure, and the program in execution to be saved, resulting in data loss of the handheld device. [0003] Therefore, someone proposes an improved method for the battery structure of the handheld device, so as to prevent the battery from falling off when the handheld device hits the ground. For example, re-mold...
