Data storage method and system for abnormal power failure of computer

Abstract

The invention provides a data storage method and system for abnormal power failure of a computer. The method comprises the steps of monitoring whether a power supply supplies power normally or not inreal time; when it is monitored that the power supply stops supplying, sending power-off information to the CPU, switching capacitor discharging supply, and controlling a preset capacitor to conduct discharging in a preset time period; and after the CPU receives the power-off information, starting a data storage program, and storing the application program in the process. According to the invention, the capacitor is preset in the power supply; then the computer power supply is monitored in real time; when it is monitored that the power supply stops supplying; the capacitor is switched to discharge so as to maintain the normal operation of the computer. According to the method, a standby power supply does not need to be connected, the user data can be protected under the conditions that thepower supply is powered off, the power line accidentally falls off and the like, the manufacturing cost is low, and the method is effective.

Description

technical field [0001] The invention relates to the field of data security, in particular to a data storage method and system for abnormal power failure of a computer. Background technique [0002] With the increasing level of science and technology, computer office has long been popularized by most companies and individuals in the world. Computers can be configured and installed with various office software, which can assist users to complete a large amount of data calculation and statistical tasks, provide convenient interaction and simplify user work. Unnecessary operations in the computer improve office efficiency, but computers rely on power to support their work, so in the event of a sudden abnormality in the power supply, user data may be lost. [0003] In the prior art, there are some solutions to sudden power outages, such as enabling the backup power supply, using UPS power supply, etc. The backup power supply refers to the power box supplied by the generator or th...
