CN103744705A - Design method capable of identifying AC\DC input and automatically starting active and standby function of power supply - Google Patents

Abstract

The invention provides a design method capable of identifying an AC\DC input and automatically starting active and standby functions of power supply and belongs to the field of power-supply operation. The design method adds the identification of the AC\DC input to the design of power supply software and automatically enables the PSU of the DC input to enter a standby state in the AC\DC input state. According to this arrangement, the design method has the advantages of being simple in power-supply operation and flexible in the power supply of servers.

Description

A kind of method for designing that judges alternating current-direct current input self-opening power supply active+standby function

 

Technical field

The present invention relates to power operation technical field, specifically a kind of method for designing that judges alternating current-direct current input self-opening power supply active+standby function.

Background technology

Along with the application that starts of server power supply active+standby function, and the bringing into use of high voltage direct current power supply technique, the operation that reply different situations realize this function becomes the focus that everybody pays close attention to.Use AC DC power and allow DC enter the backup of standby state in the situation that, although by the operation of instruction, can realize the operation of opening this function, more loaded down with trivial details, so we need to design new method, the operation of simplification to power supply.

Summary of the invention

The object of this invention is to provide a kind of method for designing that judges alternating current-direct current input self-opening power supply active+standby function, the judgement of increase to alternating current-direct current input, and according to judgement automatically AC allow the PSU of DC input enter standby state DC input in the situation that.

Thisly judge that the method for designing of alternating current-direct current input self-opening power supply active+standby function is achieved as follows:

With the state (one-byte instruction) of 80h return input, bit0 represents the state of AC, and bit1 represents the state of DC.

Such as, the content of reading from 80h is " 0x01 ", represents it is AC input at present.

The content of reading from 80h is " 0x02 ", represents it is DC input at present.

The content of reading from 80h is " 0x00 ", represents not have at present power cable to insert.

When power supply is that AC inputs or DC inputs by the judgement of state return message value when having input, and set in program, an AC input, in the time of a DC input, acquiescence enters standby state by the PSU of DC input, only have module when AC input to break down or when civil power AC disconnects, the module of DC input just can enter active state from standby state.

This method for designing can make to open active+standby function in the situation that AC DC inputs and must operate simpler.

The invention has the beneficial effects as follows:

Not only can judge AC or DC input, and can be according to the return message of input, allow AC DC input in the situation that, the PSU of DC input enters standby state.This design greatly simplified AC open the operation of active+standby function during DC input; Improve the dirigibility of server power supply, improved the competitive power of corporate server product.

Embodiment

Thisly judge that the method for designing of alternating current-direct current input self-opening power supply active+standby function is achieved as follows:

With the state (one-byte instruction) of 80h return input, bit0 represents the state of AC, and bit1 represents the state of DC.

Such as, the content of reading from 80h is " 0x01 ", represents it is AC input at present.

The content of reading from 80h is " 0x02 ", represents it is DC input at present.

The content of reading from 80h is " 0x00 ", represents not have at present power cable to insert.

When power supply is that AC inputs or DC inputs by the judgement of state return message value when having input, and set in program, an AC input, in the time of a DC input, acquiescence enters standby state by the PSU of DC input, only have module when AC input to break down or when civil power AC disconnects, the module of DC input just can enter active state from standby state.

Claims (1)

1. the method for designing that can judge alternating current-direct current input self-opening power supply active+standby function, is characterized in that concrete grammar is as follows:

With the state (one-byte instruction) of 80h return input, bit0 represents the state of AC, and bit1 represents the state of DC;

Such as, the content of reading from 80h is " 0x01 ", represents it is AC input at present;

The content of reading from 80h is " 0x02 ", represents it is DC input at present;

The content of reading from 80h is " 0x00 ", represents not have at present power cable to insert;

When power supply is that AC inputs or DC inputs by the judgement of state return message value when having input, and set in program, an AC input, in the time of a DC input, acquiescence enters standby state by the PSU of DC input, only have module when AC input to break down or when civil power AC disconnects, the module of DC input just can enter active state from standby state.
