The invention provides an energy-saving type computer power, which comprises a main power controller and a power interface connected with the main power controller. The energy-saving type computer power is characterized by also comprising a timing judging module and a switching module, wherein the timing judging module is respectively connected with the power interface and the main power controller and is used for timing the lasting time of a computer under a standby state, and when the lasting time achieves standard time, the timing judging module gives out a command to the main power controller so as to control the main power controller to cut off the power energy supply of the computer; and the switching module is connected with the main power controller and used for controlling the main power controller to supply power to the computer again. As the timing judging module and the switching module are additionally arranged on the foundation of the current power, the power supply on the computer can be automatically cut off after the computer is under the standby state for a period of time, thereby achieving the purpose of saving energy.
Description
[technical field]
The invention provides a kind of power supply, refer to a kind of energy-saving computer power that can after computer is in following a period of time of holding state, cut off automatically especially the supply of electrical energy of computer.
[background technology]
Nowadays, along with population growth and industrial development, using electricity wisely more and more comes into one's own.At present under the shut down of computer state, power supply still can export to computer main board+the wait voltage of 5V, like this, and the small part line work on the computer main board, computer is in holding state.Under holding state owing to have+5V waits for the power supply output of voltage, so still have kwh loss, especially along with the popularizing and being extensive use of of computer, the waste of getting off for a long time is still very big.
In view of this, be necessary to develop a kind of energy-saving computer power in fact, utilize this power supply, just can after computer is in following a period of time of holding state, cut off supply of electrical energy automatically, thereby reach purpose of energy saving computer.
[summary of the invention]
The object of the present invention is to provide a kind of energy-saving computer power, utilize this power supply, just can after computer is in following a period of time of holding state, cut off supply of electrical energy automatically, thereby reach purpose of energy saving computer.
For achieving the above object, the invention provides a kind of energy-saving computer power, described power supply comprises a main power control device and a power interface that is connected with described main power control device, wherein, described main power control device is in order to link to each other with civil power, described power interface is characterized in that in order to link to each other with computer described power supply also comprises:
One timing judge module, it is connected respectively with described power interface, described main power control device, described timing judge module is used for described computer is in the duration of holding state and carries out timing, when the duration reaches a standard time, described timing judge module sends an instruction to described main power control device, to control the supply of electrical energy of described main power control device cut-out to described computer;
One switch module, it is connected with described main power control device, is used to control described main power control and thinks highly of newly described computer is powered.
Especially, described switch module also is used for being in duration under the holding state when also not reaching above-mentioned standard time at computer, just controls described main power control device and cuts off supply of electrical energy to described computer.
Especially, described main power control device also cuts off the supply of electrical energy to described power interface and described timing judge module in the supply of electrical energy that cuts off described computer.
Especially, described energy-saving computer power supply also comprises a setting module, and it is connected with described timing judge module, and described setting module is in order to set the above-mentioned standard time.
Compared to prior art, the present invention just can cut off the supply of electrical energy to computer automatically, thereby reach purpose of energy saving by increase a timing judge module and a switch module on the basis of existing power supply after computer is in following a period of time of holding state.
For purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 is the block diagram of a preferred embodiment of the energy-saving computer power of the present invention.
[embodiment]
See also Fig. 1, be the block diagram of a preferred embodiment of the energy-saving computer power of the present invention, power supply 1 comprises: main power control device 11, power interface 12, timing judge module 13, setting module 14, switch module 15.Wherein, the electric energy output end of main power control device 11 links to each other with the electric energy input end of power interface 12; Power interface 12 has a PS-ON# signal end, and the input end of timing judge module 13 links to each other with the PS-ON# signal end of power interface 12, and the output terminal of timing judge module 13 links to each other with a control input end of main power control device 11; The output terminal of setting module 14 links to each other with a set input of timing judge module 13; The output terminal of switch module 15 is connected with a control input end of energy supply control module 11.
See also Fig. 1, in present embodiment, the electric energy input end of main power control device 11 links to each other with civil power 2, and the electric energy output end of power interface 12 links to each other with the input end of computer 3, thereby main power control device 11 and the power interface 12 of civil power 2 by power supply 1 provides electric energy for computer 3.
When power supply 1 respectively with after civil power 2, computer 3 are connected, the wait voltage of power supply 1 meeting generation+5V is given computer 3, computer 3 is in holding state, this moment, PS-ON# signal end signal was a high level, simultaneously, timing judge module 13 begins the duration that PS-ON# signal end signal is under the high level state is carried out timing:
1. if when the duration reaches the standard time of setting module 14 settings (as: half an hour), computer 3 is not start operation still, timing judge module 13 will send instruction to main power control device 11, after the instruction that main power control device 11 reception timing judge modules 13 send, cut-out is to the supply of electrical energy of power interface 12 and timing judge module 13, thereby cut off the supply of electrical energy to computer 3.
2. if reached in the duration before the standard time of setting module 14 settings, computer 3 existing start operations, then the PS-ON# signal end signal of power interface 12 becomes low level state, timing judge module 13 will be counted zero clearing, and main power control device 11 provides the operate as normal required voltage by power interface 12 for computer 3.
3. if reached in the duration before the standard time of setting module 14 settings, need to cut off supply of electrical energy to computer 3, then need operation switch module 15 so that main power control device 11 is controlled, the supply of electrical energy that main power control device 11 is cut off power interface 12 and timing judge module 13.
At the supply of electrical energy of main power control device 11 cut-outs to power interface 12 and timing judge module 13, after promptly cutting off supply of electrical energy to computer 3, if the user need reuse computer 3, the user at first needs operation switch module 15, so that main power control device 11 is controlled, make main power control device 11 reclose power supply supply, and then computer 3 started shooting to make the PS-ON# signal end signal of power interface 12 be that low level gets final product in operation power interface 12 and timing judge module 13.
Should be appreciated that those skilled in the art, do not break away from itself under the prerequisite of the spirit and scope of the invention that appended claims limits, can make multiple change.
