Embodiment Construction

[0014] Paralleling is a common application scenario for power supplies, and redundant backup of power supplies can be achieved through paralleling to avoid serious consequences caused by system power outages. In this application scenario, there are usually 1+1 backups, 2+2 backups, or 3+3 backups. For 2, 4 or 6 power supplies inserted into the system chassis, the order of power-on must be different. For the standby power supply that is powered on later, its processor takes power through the bus. At this time, the standby power supply will report the alarm information of input power failure and output voltage failure. In the working state, the alarm cannot be cleared actively.

[0015] Such as figure 1 As shown in the schematic diagram of the power supply structure of the first preferred embodiment of the device for clearing the power failure alarm information of the present invention, the input voltage of the power supply is converted into a DC voltage by the rectification m...

Abstract

The invention discloses a method and a device for clearing power-off alarm information. Wherein, the method includes: detecting the output voltage of the auxiliary power supply of the main power supply; when detecting that the output voltage of the auxiliary power supply rises, clearing the power-down warning information of the power supply; or detecting the input voltage of the power supply; When the input voltage to the power supply rises and the rising range satisfies a preset threshold, the power-down warning information of the power supply is cleared; the present invention also provides a power-down warning information clearing device. The present invention solves the problem that after the power is supplied, the power warning indicator light is not cleared in time, which increases the burden on the system, and the power indicator light keeps on or flashes to remind, which affects the user experience.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a method and device for clearing power-off alarm information. Background technique [0002] The protection and alarm function of the communication chassis and cabinet power supply system is a necessary part of the communication power supply. This function can effectively prevent equipment damage and communication link interruption caused by power failure. Paralleling is a common application scenario for power supplies. Paralleling is used to implement redundant backup of power supplies to avoid serious consequences of business interruption caused by system power outages. [0003] The power-on sequence of parallel power supplies is different. Taking 1+1 backup as an example, it is assumed that the main power supply is powered on first, and then the backup power supply is powered on. After the main power supply is powered on, the standby power supply has no input, but its processor o...
