Power supply power management method and device as well as modularizing equipment

Abstract

The invention provides power supply power management method and device as well as modularizing equipment. The method comprises the following steps of: setting corresponding power-off strategies of business modules when all power supply modules and the combination of various power supply modules can not supply power according to the available power of all the power supply modules, the needed powerof all the business modules and the priority of all the business modules; detecting power supply states of all the power supply modules in real time; and if detecting that one power supply module cannot normally supply power, controlling the corresponding business module to carry out the power-off operation according to the power-off strategy. The invention realizes the rapid powering-off of thebusiness modules on the basis of not adding additional power supply into the modularizing equipment or temporarily carrying out polling judgment operation of power on all the business modules when the output power of a power supply is insufficient, rapidly solves the problem of output power shortage of the power supply and prevents the generation of the whole machine power-off phenomenon caused by overlong overloading time of a bus power supply.

Description

technical field [0001] The invention relates to power management technology, in particular to a power management method, device and modular equipment, belonging to the field of electronic technology. Background technique [0002] With the rapid development of network technology, the port density, bandwidth, and speed of modular equipment are getting higher and higher, resulting in more and more power consumed by modules. At the same time, the number of service module slots set by modular equipment is increasing. , and further requires modular equipment to provide greater system power to meet the power requirements of multi-service modules. In order to meet this demand, the modular equipment proposes a multi-power supply cooperation scheme, that is, multiple power supplies are installed in a modular equipment at the same time to provide the required power for each business module. Therefore, in the working process of a switching system with multiple power supplies, multiple...
