Switch power supply rectifier module monitoring and early warning method and system

Abstract

The invention provides a switch power supply rectifier module monitoring and early warning method and system. The method comprises the steps that the historical operation data and the real-time operation data of a switch power supply are acquired; according to the formula that n=If+Ib / Im, the rectifier module number of the switch power supply is calculated; whether the rectifier module number of the switch power supply and the registered rectifier module number of the switch power supply are the same is judged; if so, the rectifier module number of the switch power supply is output; and otherwise, early warning information is output. Compared with the prior art, the method and the system, which are provided by the invention, have the advantages that the shortcomings of a man-made notification way are overcome; the accuracy and the timeliness of switch power supply rectifier module monitoring are improved; the problem of switch power supply rectifier module miss monitoring is prevented; and the safety of the power supply of a switch power supply system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of communication power supply monitoring, in particular to a monitoring and early warning method and system for a switching power supply rectifier module. Background technique [0002] In the mobile communication network, the switching power supply provides DC current for the communication equipment, which is the guarantee for the uninterrupted operation of the entire mobile communication network. The rectifier module in the switching power supply is responsible for completing the conversion of AC to DC current. It is the core part of the power output of the switching power supply and plays a vital role in the switching power supply system. In the switching power supply system, multiple rectification modules are generally connected in parallel. The sum of the output currents of each rectification module is the total output current of the system. The position of the rectification module in the switching power...
