Step 406: the system that detects hot-plug equipment sends querying command to equipment interface once more.
Step 407: the response of whether receiving hot-plug equipment in default wait duration is judged by the system that detects hot-plug equipment, if then continue step 403, otherwise continue step 408.
Step 408: the system that detects hot-plug equipment determines that no hot-plug equipment is connected with FIU facilities interface unit, and flag is changed to 0 with identifier.
Above flow process is an one-period, and after the system of detection hot-plug equipment determined that no hot-plug equipment inserts equipment interface, through the preset period duration, the equipment interface to self sent querying command once more, and promptly execution in step 401.
By above description, to have understood and detected the implementation procedure that whether has hot-plug equipment to insert, this process mainly realizes by the system that detects hot-plug equipment, inner structure and the function to the system that detects hot-plug equipment is introduced below.
Referring to Fig. 5, the system that detects hot-plug equipment in the present embodiment comprises: FIU facilities interface unit 501, electric supply installation 502 and control device 503.
FIU facilities interface unit 501 is used to connect hot-plug equipment.
The power end of the voltage output end connection device interface arrangement 501 of electric supply installation 502 is used to equipment interface power supply or outage.
The data terminal of the data terminal connection device interface arrangement 501 of control device 503, and control end EN1 connects the control end of electric supply installation 502, be used for sending querying command to FIU facilities interface unit 501, when not receiving the response of hot-plug equipment, by powering on behind the electricity under the power end of electric supply installation 502 opertaing device interface arrangements 501, and send querying commands to FIU facilities interface unit 501 once more.Control device 503 specifically is used for sending first signal that is used to indicate the electric supply installation outage to the control end of electric supply installation 502, and the control end to electric supply installation 502 sends the secondary signal that is used to indicate the electric supply installation power supply behind the delay duration that postpones to preset.Control device 503 is once more after FIU facilities interface unit 501 sends querying commands, determines that no hot-plug equipment is connected with FIU facilities interface unit 501 during the response of not receiving hot-plug equipment.
The voltage output end of electric supply installation 502 is also by electric capacity 504 ground connection, referring to shown in Figure 6.The power supply of hot-plug equipment was stable when this electric capacity 504 was used to guarantee the hot-plug equipment operate as normal.
The voltage output end of electric supply installation 502 is also by electric discharge device 505 ground connection.This electric discharge device 505 is used for shortening the discharge time of electric capacity 504, but can not making the voltage of FIU facilities interface unit 501 become 0 at once when 501 outages of 502 pairs of FIU facilities interface unit of electric supply installation.Electric discharge device comprises the switching device of being with control end, manages as Metal-oxide-semicondutor (MOS) etc.
Another control end EN2 of control device 503 connects the control end of switching device, and passes through the break-make of this control end gauge tap device.
Wherein, control device 503 comprises processing unit and converting unit.
Processing unit (as CPU) is used to realize software logic.
Converting unit is used for the software command that processing unit generates is converted to electric signal output, and receives electric signal, and is converted to form of software and sends to processing unit.
Concrete, the order of processing unit generated query also sends to converting unit.Converting unit sends to FIU facilities interface unit 501 by data terminal.Whether processing unit receives hot-plug equipment in default wait duration response, if, then defining hot-plug equipment and insert, flag is changed to 1 with identifier, otherwise generates first signal (EN1=0) and the 3rd signal (EN2=1).Converting unit is that high level (also can be low level) signal sends to electric supply installation 502 with first conversion of signals, indicates its outage; And be that high level (if electric discharge device 505 is low level conductings, can be low level also then, adopt the electric discharge device of high level conducting in the present embodiment) signal sends to electric discharge device 505 with the 3rd conversion of signals, indicate it to begin discharge.Processing unit postpones default delay duration (as 1ms) back and generates secondary signal (EN1=1) and the 4th signal (EN2=0).Converting unit is converted to low level (also can be high level) signal with secondary signal and sends to electric supply installation 502, indicates its power supply; And be that low level (also can be high level) signal sends to electric discharge device 505 with the 4th conversion of signals, indicate it to stop discharge.Processing unit is through postponing behind the duration generated query order once more and sending to converting unit, and judge the response of in default wait duration, whether receiving hot-plug equipment, if, then defining hot-plug equipment is connected with FIU facilities interface unit, flag is changed to 1 with identifier, otherwise determine that no hot-plug equipment is connected with FIU facilities interface unit, flag is changed to 0 with identifier.Generated query order once more behind the processing unit process preset period duration (as 5s).
Be used to realize that the software of the embodiment of the invention can be stored in storage mediums such as floppy disk, hard disk, CD and flash memory.
When the system that detects hot-plug equipment in the embodiment of the invention does not receive hot-plug equipment at the response of querying command, control the power end electricity and powering on down of the equipment interface of self, send querying command to hot-plug equipment once more after powering on.Under the situation that has hot-plug equipment to insert, the response of not receiving hot-plug equipment, then deadlock may take place in hot-plug equipment.The system that detects hot-plug equipment descends electricity and powers on hot-plug equipment is restarted by the power end to equipment interface, no longer needs the artificial hot-plug equipment of plug again, also just can not occur the situation of VOUT electric voltage dropping again.The system that detects hot-plug equipment sends querying command to hot-plug equipment once more, and this moment, hot-plug equipment recovered normally can receive querying command.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
