Abstract
The embodiment of the invention provides a single-power multi-mainboard power supply management system. The power supply management system comprises a plurality of mainboards and an ATX power source used for powering the mainboards and connected with the mainboards through power lines with switch circuits thereon. The power supply management system further comprises a power supply management module which is connected with each mainboard through a data cable and also connected with the switch circuits. The shutdown signal of each mainboard is sent to the power supply management module through the data cable, rather than to the ATX power source; the switch circuit on the power line corresponding to the mainboard sending the shutdown signal is turned off by the power supply management module according to the received shutdown signal, so that the single-power multi-mainboard power supply management is realized, and the reliability of the mainboard running is ensured without configuring a plurality of power sources.
Description
Technical field
the present invention relates to field of information security technology, especially relate to a kind of many main board power supplies of single supply management system.
Background technology
along with scientific and technological development, popularizing of computing machine is more and more higher.At present, the power supply that microcomputer mainly adopts mostly is ATX power supply, and its effect is that the power supply of alternating current 220V is converted to direct current 3.3V, the 5V of computer motherboard and peripheral hardware use, the power supply of 12V, 24V.
power supply is compared AT type power supply has increased "+3.3V ,+5VSB, PS-ON " three outputs.Wherein "+3.3V " output is mainly for internal memory, and "+5VSB ", " PS-ON " output has embodied the feature of ATX power supply.The topmost feature of ATX power supply is exactly, whether it does not adopt traditional urban electric power switch to control power supply and works, but the combination that adopts "+5VSB, PS-ON " realizes the opening and closing of power supply, as long as control the variation of " PS-ON " signal level, just can control the opening and closing of power supply.Power-on when " PS-ON " is less than 1V volt, powered-down while being greater than 4.5 volts.During shutdown, ATX power supply itself does not have thorough power-off, but has maintained a fainter electric current.It utilizes this electric current to increase a power management function simultaneously, is called Stand-By.It can allow operating system directly power supply be managed.By this function, user just can directly realize soft-off by operating system.Due to the These characteristics of existing ATX power supply, cause existing ATX power management to be also only suitable in the situation of single supply single operating system simultaneously.
if a computing machine has plural mainboard, and each mainboard has all moved operating system, the power management of the operating system of each mainboard will tanglewrack, probably cause one of them mainboard just when working procedure, the power management routines of the operating system of another mainboard is but controlled ATX power supply shutdown, causes that system is unstable and data security is poor.
Summary of the invention
for the problem of current computer poor stability, the embodiment of the present invention has proposed a kind of many main board power supplies of single supply management system that can make each operating system manage power supply in the situation that of many mainboards of single supply.
to achieve these goals, the embodiment of the present invention provides a kind of many main board power supplies of single supply management system, comprising: a plurality of mainboards and for giving the ATX power supply of a plurality of main board power supplies; Wherein this ATX power supply connects described a plurality of mainboard by power lead respectively, and described power lead is provided with on-off circuit; Also comprise power management module, described each mainboard connects described power management module by data line, and described power management module connects described on-off circuit.
as technique scheme preferably, described system also comprises man-machine interface, described man-machine interface connects described power management module.
as technique scheme preferably, described mainboard is x86 mainboard.Described power management module is A8 double-core arm processor.
the invention has the beneficial effects as follows: the present invention proposes a kind of many main board power supplies of single supply management system, the off signal of each mainboard is not to send to ATX power supply by data line, but send to power management module, then according to the off signal that receives, close by power management module the on-off circuit sending on the power lead that the mainboard of this off signal is corresponding.So just can realize the many main board power supply management of single supply, without a plurality of power supplys of configuration, can guarantee again each mainboard reliability of operation.
Accompanying drawing explanation
by the description of a preferred embodiment of the present invention being carried out below in conjunction with accompanying drawing, it is clearer that technical scheme of the present invention and technique effect thereof will become, and easy to understand more.Wherein:
fig. 1 is the principle schematic of many main board power supplies of single supply management system of the embodiment of the present invention;
fig. 2 is the circuit connection diagram of Fig. 1.
Embodiment
below with reference to appended accompanying drawing, a preferred embodiment of the present invention is described.
the embodiment of the present invention low problem of security that the power management confusion under many mainboard structure causes for the ATX power supply of prior art Computer, a kind of many main board power supplies of single supply management system has been proposed, its structure as shown in Figure 1, comprises a plurality of mainboards 2 and for the ATX power supply 3 to a plurality of mainboards 2 power supplies in this main frame 1; Wherein this ATX power supply 3 connects described a plurality of mainboard 2 by power lead respectively.As shown in Figure 1, also comprise power management module 4, described each mainboard 2 connects described power management module 4 by data line, and described power lead is provided with on-off circuit, the described on-off circuit of described power management module 4 connection.Like this when work, the off signal of each mainboard 2 is not to send to ATX power supply 3 by data line, but send to power management module 4, then according to the off signal receiving, close by power management module 4 on-off circuit sending on the power lead that the mainboard of this off signal is corresponding.So just can realize the many main board power supply management of single supply, without a plurality of power supplys of configuration, can guarantee again each mainboard reliability of operation.As shown in Figure 1, this main frame 1 also comprises man-machine interface 5, and described man-machine interface 5 connects described power management module 4, to control described power management module 4 and it is programmed.Wherein said ATX power supply 3 is direct-current switch power supply.
as shown in Figure 2, described mainboard 2 is x86 mainboard.Described power management module 4 is A8 double-core arm processor.
the said system that the embodiment of the present invention proposes, can utilize any type of computer hardware to realize, and the present invention does not make restriction to this.
for person of ordinary skill in the field, along with the development of technology, the present invention's design can realize by different way.Embodiments of the present invention are not limited in embodiment described above, and can change within the scope of the claims.
