Fig. 2 is a kind of side being powered based on CPCI power supplys to the mainboard of terminal according to an exemplary embodiment
The flow chart of method.As shown in Fig. 2 this method is used in terminal, the terminal is configured with CPCI power supplys, mainboard and single-chip microcomputer.The party
Method comprises the following steps：
Step 201：In the case where external power supply is powered, when mainboard detects power-on operation, send and open to single-chip microcomputer

Fig. 3 A are that a kind of according to an exemplary embodiment is powered based on CPCI power supplys to the mainboard of terminal
The flow chart of method.The embodiment of the present invention will carry out expansion discussion with reference to accompanying drawing 1 to the embodiment shown in Fig. 2.This method is used for
CPCI power supplys, mainboard and single-chip microcomputer are configured with terminal, in terminal, is comprised the following steps：
Wherein, the terminal can not only be configured with CPCI power supplys, mainboard and single-chip microcomputer, and alternatively, the terminal can also wrap
Electric pressure converter is included, can first 301-302 be obtained by electric pressure converter in accordance with the following steps in the case where external power supply is powered
The second output voltage is obtained, operating voltage is provided for single-chip microcomputer and provides standby voltage for the holding state of mainboard.Need to illustrate
, external power supply is generally the alternating current of 220V (volt), is normal voltage the most frequently used in current most of living scenes.
Step 301：In the case where external power supply is powered, electric pressure converter is changed to the voltage of external power input
Processing, obtains the second output voltage.
Due to the mainboard of terminal, required standby voltage is relatively low in the standby state, and required work when single-chip microcomputer works
Voltage is relatively low, and CPCI power supplys can not provide this kind of relatively low voltage, and then cannot be provided for the mainboard of terminal and treat electromechanics
Pressure, operating voltage can not be provided for single-chip microcomputer, therefore can be changed the alternating voltage of external power supply by electric pressure converter
For the second output voltage, standby voltage is provided for mainboard, and operating voltage is provided for single-chip microcomputer.
It should be noted that the operating voltage needed for standby voltage and single-chip microcomputer needed for mainboard is generally 5V direct current
Electricity, therefore, full bridge rectifier can also be included in electric pressure converter, alternating current can be changed by the full bridge rectifier
For 5V direct current.
Step 302：Electric pressure converter exports the second output voltage respectively to single-chip microcomputer and mainboard, to provide work for single-chip microcomputer
Make voltage, and standby voltage is provided for mainboard.
For example, after external electric power starting, 220V alternating current can be exported, the alternating current to CPCI power supplys except supplying
It is electric outer, 5V direct current by electric pressure converter, can also be exported, for providing operating voltage for single-chip microcomputer, is ensured single
Piece machine normal work, while providing the voltage required for holding state for mainboard.
Second output voltage is converted to by electric pressure converter, to provide operating voltage for single-chip microcomputer, and is mainboard
After providing standby voltage, mainboard can be in holding state, and single-chip microcomputer can also be in normal operating conditions, afterwards can be according to
Following steps 303-305 opens mainboard, makes mainboard in running order.
Step 303：In the case where external power supply is powered, when mainboard detects power-on operation, send and open to single-chip microcomputer
Machine signal.
Because, in the case where external power supply is powered, CPCI power supplys can start immediately in correlation technique and output voltage,
Be, no matter whether mainboard open, CPCI power supplys all can output voltage, however, in the case where mainboard is closed, CPCI power supplys are defeated
The voltage gone out can not be effectively utilized, and therefore, can cause the certain power consumption of CPCI power loss.Therefore, in the present invention
In embodiment, CPCI power supplys are opened while being opened with control mainboard, to reduce the power consumption of CPCI power supplys.At this time, it may be necessary to will
The starting-up signal of mainboard is sent to CPCI power supplys, however, because mainboard does not have the function of being communicated with CPCI power supplys, because
This, in embodiments of the present invention, adds a single-chip microcomputer, by the communication between chip microcontroller mainboard and CPCI power supplys, this
Sample, in the case where external power supply is powered, a starting-up signal can be produced when mainboard detects power-on operation, and this is opened
Machine signal is sent to single-chip microcomputer.
Wherein, referring to Fig. 1, in the case where terminal includes button 107, user can be with pressing keys 107, and then trigger and open
Machine operates, naturally it is also possible to power-on operation is triggered by other means, such as, triggered out by the control of other remote terminals
Machine operates, and the present invention is without limitation.In addition, referring to Fig. 1, in the case where terminal includes alternating-current switch, for the ease of behaviour
Make, CPCI power supplys can be connected with external power supply all the time, when needing external power supply to power, alternating-current switch can be opened, when not
When needing the external power supply to power, alternating-current switch can be closed.
It is worth noting that, in the embodiment of the present invention, mainboard can be believed to the starting-up signal that single-chip microcomputer is sent by numeral
Number form realize, certainly, in practical application, can also be realized by the form of high level signal or low level signal, such as,
Mainboard can send a low level signal to single-chip microcomputer, to represent starting-up signal.
For example, when external power supply is powered, user can be with pressing keys 107, and now mainboard can detect power-on operation, enter
And producing a starting-up signal PS_ON, it is assumed that starting-up signal PS_ON realizes in the form of low level signal, now, mainboard meeting
A low level signal is sent to single-chip microcomputer, to transmit starting-up signal PS_ON to single-chip microcomputer.
Step 304：When single-chip microcomputer receives the starting-up signal of mainboard transmission, sent to the first control terminal of CPCI power supplys
First level signal, and after preset duration, second electrical level signal is sent to the second control terminal of CPCI power supplys.
In order to reach startup CPCI power supplys while mainboard is opened, to save the purpose of power consumption, when single-chip microcomputer receives
During the starting-up signal that mainboard is sent, the starting-up signal can be sent to CPCI power supplys.Due in the embodiment of the present invention, single-chip microcomputer
It can be connected with the first control terminal of CPCI power supplys, also, for the ease of realizing, single-chip microcomputer can be to the first control of CPCI power supplys
End processed sends the first level signal, to indicate that mainboard currently has been switched on by the first level signal.Again due to CPCI power supplys from
Starting-up signal is received to also needing to experience a period of time between normal work, and in the embodiment of the present invention, single-chip microcomputer can be with
The second control terminal connection of CPCI power supplys, therefore, single-chip microcomputer can also be after preset duration, to the second control terminal of CPCI power supplys
Second electrical level signal is sent, the output voltage for being used to refer to CPCI power supplys is normally established, can that is to say with normal work,
The first output voltage of output can be started and think main board power supply.
It should be noted that after preset duration receives starting-up signal for power supply, until can be that is to say with normal work,
Output voltage normally establishes required duration.In actual implementation process, the preset duration is generally 0.1 second~0.5 second.Separately
Outside, the first level signal and second electrical level signal are different types of level signal, example, if the first level signal is low electricity
Ordinary mail number, second electrical level signal can be high level signal, certainly, if the first level signal is high level signal, second electrical level
Signal can be low level signal.
Because the embodiment of the present invention employs single-chip microcomputer and CPCI power supplys are used in combination, by single-chip microcomputer to CPCI power supplys
First control terminal, the second control terminal configure different level signal, and by the start in these different level signals and mainboard
Signal is mapped, it is possible to achieve the opening of CPCI power supplys is controlled using single-chip microcomputer, and then realizes and is opened while mainboard is opened
Dynamic CPCI power supplys.
For example, when single-chip microcomputer receives the starting-up signal PS_ON of mainboard transmission, the starting-up signal is sent to CPCI electricity
Source, it is assumed that starting-up signal PS_ON is realized in the form of low level signal, that is to say, the first level signal is with low level shape
Formula is realized, because single-chip microcomputer can be connected with the first control terminal of CPCI power supplys, it is assumed that the first control terminal is programmable pin
The low level signal can be sent to the pin EN# of CPCI power supplys by EN#, now, single-chip microcomputer, for indicating present motherboards
Open.Assuming that preset duration is 0.2 second, because single-chip microcomputer can be connected with the second control terminal of CPCI power supplys, it is assumed that the second control
End processed is programmable pin INH#, and second electrical level signal is realized in the form of high level, therefore single-chip microcomputer can be to after 0.2 second
The pin INH# of CPCI power supplys sends the high level signal, for indicating that CPCI power supplys can start normal work.
Further, because CPCI power supplys are from starting-up signal is received to when also needing to undergo one section normal work
Between, it that is to say, when CPCI power supplys receive starting-up signal, normal work will not be got started, and then would not get started
Export the first output voltage.Again because the embodiment of the present invention using CPCI power supplys provides operating voltage for mainboard, if CPCI is electric
Source does not export the first output voltage, and mainboard can not then start, and then mainboard can not detect whether CPCI power supplys have begun to
Normal work, therefore, after preset duration, after single-chip microcomputer sends second electrical level signal to the second control terminal of CPCI power supplys,
Single-chip microcomputer can also send enabling signal to mainboard, and the enabling signal is used to indicate that mainboard starts to start.Wherein, for the ease of reality
Existing, enabling signal can be realized by the form of second electrical level signal, that is to say, second electrical level signal is sent to master by single-chip microcomputer
Plate, to represent that power supply is already prepared to, it can start to export the first output voltage, for mainboard normal work.
, can be with after single-chip microcomputer sends second electrical level signal to the second control terminal of CPCI power supplys for example, after 0.2 second
An enabling signal is sent to mainboard, the enabling signal is second electrical level signal, it is assumed that second electrical level signal is believed with high level
Number form realize, that is to say, the P_OK signals in mainboard are realized in the form of high level, for indicating that power supply has been prepared for
