Embodiment Construction

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0024] The power failure protection method provided by the embodiments of the present invention is applied to the X86 architecture. When the system is powered off, the backup battery is activated to save data and program operation breakpoints; the power supply is detected, and the backup battery is charged when the power supply is restored.

[0025] Such as figure 1 As shown, the power-off protection method provided by the embodiment of the present invention includes the following steps:

[0026] In step S101, when the PC is turned on, the AC is powered on, and the system starts to run window XP an...

Abstract

The present invention, which is applicable to the computer field, provides a power failure protection method. The method includes: starting a standby battery to supply power to a computer system in power failure and storing data and program break point in a memory into a special storage device; utilizing a recovered AC power supply to charge the standby battery. When the AC power supply of the computer system is abnormal, the embodiment of the present invention utilizes the standby battery for power supply and automatically protects the field program data and the break point. After recovering, the AC power is used to charge the standby battery so as to ensure the standby battery can work when the AC power is off and increase the reliability of power failure protection.

Description

Technical field [0001] The invention belongs to the computer field, and particularly relates to a power failure protection method, device and system. Background technique [0002] Like the commercial machine, the power supply of the industrial computer is also the alternating current (AC) power supply of the mains. When the AC power supply is abnormal, such as power failure, undervoltage, peak pulse, etc., it may cause the industrial computer to shut down or restart unsafely. Therefore, in addition to the part of the software that comes with the function of refreshing and saving data regularly, other on-site operating environments, parameters, and data of the industrial computer will be lost, which may cause catastrophic losses to customers applied to industrial sites. [0003] In view of this, the power-off protection scheme of industrial computer is generally introduced, such as using the automatic save function of the software, regardless of whether the AC power supply is abnorm...
