Power supply control method and control system

Abstract

The invention discloses a power supply control method and control system and relates to the technical field of communication system power supply. The method and system are used for improving load power supply rate of external power supply devices. The power supply control method includes acquiring a power supply signal of an external power supply device and starting a backup power source for supplying power for a load when power supply to the load from the external power supply device is interrupted; controlling the external power supply device to supply power to the load independently at a first preset voltage when the external power supply device restores power supply; if that the power supply duration of the external power supply device supplying power to the load independently reachesa target time length, controlling the external power supply device to supply power to the load and the backup power source at the same time at a second preset voltage, wherein the second preset voltage is greater than the first preset voltage. The method and system provided by the invention are used for power supply control for communication devices in a communication system.

Description

technical field [0001] The present invention relates to the technical field of communication system power supply, in particular to a power supply management and control method and a management and control system. Background technique [0002] At present, in industries involving data communication such as communications, servers, and monitoring security, in order to ensure the stable use of each communication system, a backup power supply is usually configured for each communication system, so that when the external power supply equipment is powered off, the backup power supply is used to supply power to each communication system. The load of the communication system is directly powered or inverted. Since the backup power supply is usually a rechargeable power supply, after the external power supply equipment resumes power supply, it is generally necessary for the external power supply equipment to charge the backup power supply immediately, so as to prepare for emergency use...

AI Technical Summary

Problems solved by technology

[0003] However, when the external power supply equipment resumes power supply, the external power supply equipment not only needs to supply power to the loads of each communication system, but also needs to supply power to its backup power at the same time, so that the power capacity required by the external power supply equipment can not only meet the needs of the loads. In addition to the load power supply capacity, it is also necessary to reserve enough charging capacity for each backup power supply to store electricity, such as reserving 15% of the total power capacity of the external power supply equipment, so that it is easy to restore power at the beginning of the external power supply equipment, due to the large number of backup power supplies Centralized charging causes the problem of additional load power supply capacity of external power supply equipment, resulting in low load power supply rate of external power supply equipment
