A power monitoring method, system and server

Abstract

The invention discloses a power supply monitoring method, which detects whether the communication link between the power supply and a monitoring device for monitoring the working status of the power supply is interrupted; if it is not interrupted, it is determined that the power failure alarm of the monitoring device is valid; if interrupted, the Determine that the power failure alarm of the monitoring device is invalid, and reset the communication port of the power supply and the monitoring device and the communication bus between the two, so as to repair the communication link between the two. It can be seen that when the communication between the monitoring device and the power supply is interrupted, the present application determines the false alarm of the monitoring device and repairs the communication link between the monitoring device and the power supply, thereby avoiding the false alarm problem caused by the interruption of communication between the monitoring device and the power supply. The invention also discloses a power monitoring system and a server, which have the same beneficial effects as the above power monitoring method.

Description

technical field [0001] The invention relates to the field of power monitoring, in particular to a power monitoring method, system and server. Background technique [0002] The server in the data center plays an important role in data calculation and storage. Once the power supply of the server fails, the server will be down, which will easily cause the data loss of the server. At present, in order to avoid data loss caused by power failure, a power system consisting of two identical power supplies is configured for the server, and a monitoring device for monitoring the working conditions of the two power supplies is configured for the power system. When the monitoring device monitors When one power supply fails, another power supply takes over the power supply to continue to ensure the normal operation of the server. However, during the communication process between the monitoring device and the power supply, electromagnetic interference may cause the handshake failure and ...

AI Technical Summary

Problems solved by technology

However, during the communication process between the monitoring device and the power supply, due to electromagnetic interference, the handshake between the two may fail and the communication may be interrupted. At this time, the monitoring device cannot monitor the power supply, and will issue a power failure alarm, thereby causing false alarms.
