Problems solved by technology
[0004] There is following shortcoming in above-mentioned method: because not every kind of application program has automatic saving function, therefore, when the situation such as sudden power failure occurs, the computer data of the application program that does not have automatic saving function will be lost, and this will cause unnecessary loss to the user. Loss
[0005] For applications with automatic save function, the degree of computer data protection is limited by the interval time of automatic save, that is, if a sudden power failure occurs before the next save interval, some computer data will be lost due to not being saved. Actual data protection is less than ideal

Description
technical field [0001] The invention relates to the field of electronic information security, in particular to a computer automatic protection power supply device and protection method for preventing sudden power failure. Background technique [0002] The wide application of computers has greatly enhanced the ability of human beings to transform nature. Nowadays, new computer technologies are constantly emerging, and people can use computers to implement various applications, which makes people's life and work more convenient and efficient. [0003] Since computers process data through programs to realize various applications, it is very important to protect computer data against emergencies. In particular, the protection of computer data is very important when the power is cut off (that is, the external AC power supply is powered off). The prior art realizes the protection of computer data, generally through the automatic saving function of the application program, that is...
