Abstract

The invention discloses a power failure protection method, device and system, wherein the method comprises following steps of detecting whether a single board for bearing service has a service abnormity or not; detecting whether a power supply board has undervoltage alarm or not; detecting whether the current voltage of the power supply board is normal or not; when the single board has the service abnormity, the power supply plate has the undervoltage alarm and the current voltage of the power supply board is normal, restarting the single board, thus reconfiguring the single board. Through adoption of the method, the device and the system, the problem that the service is interrupted all the time is solved, the problem results from the fact that the output of the power supply module for supplying power to the single board central processing unit for bearing the service is not switched off, while the output of the power supply module of a service chip is powered off, and the service of the single board is prevented from being interrupted all the time.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a power-down protection method, device and system thereof. Background technique [0002] Usually, a communication device at one end consists of two or more single boards. At present, two or more power modules are generally used to supply power to a single board. The threshold value of each power module output shutdown is different. When a power failure occurs, it will be replaced by a battery for power supply. Due to the limited capacity of the battery, the output voltage It will gradually drop to the point where the equipment cannot operate; when the voltage drops to a certain range, the output of some power modules inside the board will be turned off, while some power modules will work normally. [0003] If the normal power supply is restored in this case, the output of the power supply module powered by the single-board central processing unit (CPU) that carries the busines...
