Problems solved by technology

But now most desktop computers use household power as the main power supply method, and there is a problem: when there is a sudden power failure, the desktop computer will stop working, and some important data in our hard disk will often be lost because of this; Electricity will cause the read-write head of the hard disk to rub violently against the disk, causing damage to the hard disk and causing immeasurable losses

Embodiment 1

[0027] see Figure 1~2 , in an embodiment of the present invention, a computer power-off protection system includes a data protection control module 100, a log generation module I300, a log generation module II400, a hard disk module 500, and an energy storage capacitor 800;

[0028] In this embodiment, the log generation module 1300 communicates with the data protection control module 100 for recording all data information to be read and written by the hard disk module 500 when a power failure occurs;

[0029] The log generation module II400 communicates with the data protection control module 100, and is used to record the read and write records of all data information to be read and written under the power supply of the energy storage capacitor 800;

[0030] The data protection control module 100 controls the reading and writing work of the hard disk module 500 until the hard disk head is reset, and executes the power-off program. After the computer is normally turned on, t...

Embodiment 2

[0036] see image 3 , in an embodiment of the present invention, a computer power-off protection method, comprising the following steps:

[0037] S1, after the external power supply is cut off, the detection module sends a message to the power control module after detecting the voltage change signal, and makes the energy storage capacitor supply power through the power switching circuit;

[0038] S2, under the continuous power supply of the energy storage capacitor, control the reading and writing work of the hard disk module 500 until the hard disk head is reset, and execute the power-off process. The data information is written into a log, and the log generation module II400 writes the read and write records of all data information to be read and written after this part of the power is cut off into a log;

[0039] S3, after the computer is turned on, control the hard disk module 500 to send the results of the log generation module I300 and the log generation module II400 to...

Abstract

The invention discloses a computer power-off protection system, which relates to the technical field of computers, and comprises: a log generation module I which communicates with a data protection control module and is used for recording all data information to be read and written by a hard disk module when power off occurs; a log generation module II which communicates with the data protection control module and is used for recording read-write records of all data information to be read and written under the power supply of the energy storage capacitor; a data protection control module whihch is used for controlling the read-write work of the hard disk module until the hard disk magnetic head is reset and executing a power-off program. The beneficial effects of the invention are that:during power failure of computer, power supply is continuously kept through the energy storage capacitor, and after the computer is normally started, results of the log generation module I and the log generation module II are sent to the computer processor, so that a user knows which data is read and written completely after power failure and which data is not read and written or stopped, and the user knows the data conveniently.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a computer power-off protection system and method. Background technique [0002] The emergence and development of computers is one of the most important scientific and technological achievements in the 20th century. Computers have penetrated into various fields of the national economy and society, greatly changing people's lifestyles and working methods, and becoming a huge productive force to promote social development. At the same time, with the development of modern technology, new types of computers such as notebook computers and all-in-one computers have also appeared. But now most desktop computers use household power as the main power supply method, and there is a problem: when there is a sudden power failure, the desktop computer will stop working, and some important data in our hard disk will often be lost because of this; Electricity will make the read-write head of ...
