Portable electronic device and information protecting method thereof

Abstract

The invention relates to a portable electronic device which is provided with a volatile memory, a nonvolatile memory, a processing unit and an acceleration sensing module, wherein the acceleration sensing module is used for detecting an acceleration value of the portable electronic device; and the processing unit processes acceleration information and transmits a command to copy information in the volatile memory into the nonvolatile memory when the acceleration value is larger than or equal to a safe moving range parameter. The portable electronic device can sense the moving acceleration thereof and start a backup program during falling down; therefore, the portable electronic device has enough reaction time for copying the probably lost information and prevents the information loss caused by falling. The invention also provides an information protecting method of the portable electronic device.

Description

Technical field [0001] The present invention relates to a portable electronic device, and more particularly to a portable electronic device capable of completely backing up data when falling to prevent data loss. Background technique [0002] Existing portable electronic devices, such as mobile phones, media players, etc., if they accidentally fall to the ground while in use, not only will they cause damage to their appearance, but more seriously, the battery of the portable electronic device may become loose or even loose due to falling to the ground. If the portable electronic device is suddenly powered off, the information in the random access memory (RAM) is lost. Even if the battery is installed again, the information in the original operation process has been lost, causing inconvenience to the user. [0003] To solve this problem, some portable electronic devices are equipped with power-off protection devices. The power-off protection device includes a battery current detect...

AI Technical Summary

Problems solved by technology

[0004] This power-off protection device is a passive protection device, that is, when the power-off protection device detects a sudden drop in circuit voltage, it will activate the backup battery or capacitor, but the sudden drop in voltage is very rapid. If the mobile phone falls to the ground and hits Violent, if the battery comes out too quickly, the protection device may not be able to respond in time, and the backup battery or capacitor will be activated in time, resulting in the loss of information in the random access memory.

Moreover, due to the small size of the mobile phone itself, limited by the internal space of the mobile phone, the spare battery and capacitor are small in size and store less power, which can only be maintained for a very short period of time. If this time is exceeded, the battery still cannot recover If the mobile phone is powered, the information in the random memory of the mobile phone will be lost due to power failure, which will cause inconvenience to the user.
