A kind of information processing method provided by the embodiments of the present application specifically can be applied to have in the electronic equipment of disk,
The electronic equipment can be the electronic equipments such as mobile phone, digital camera/tablet computer, laptop, be also possible to other electricity
Sub- equipment, here, just different one schematically illustrating.
With reference to the accompanying drawing to main realization principle, specific embodiment and its correspondence of the embodiment of the present application technical solution
The beneficial effect that can reach is explained in detail.
Embodiment one
Referring to FIG. 1, the embodiment of the present invention provides a kind of information processing method, comprising:
S101: in the first preset time period, processor detection obtains the first access letter of the access for multiple disks
Breath, wherein the processor is connect with the multiple disk；
S102: being based on first access information, determine the first disk, which is first preset time
The disk of access is not received in section in the multiple disk；
S103: control the first disk power down.
In the embodiment of the present application, specifically: by taking multiple disks include disk A, disk B, disk C and disk D as an example, place
Reason device is connect with disk A, disk B, disk C and disk D respectively, and detection is directed to the access of multiple disks within a preset period of time,
And obtain the first access information.
In the embodiment of the present application, since detected first parameter is different, the specific implementation of step S102 is not
Together, specifically, step S102 at least has following two specific implementation, but both implementations are not limited only to:
First way: according to the corresponding relationship of preset interface class and disk, determined from the multiple disk with
The corresponding disk for receiving access of the interface class and the first disk for not receiving access.
Disk can receive the access by particular types interface, and when there is the access for disk to occur, detection is connect
The interface class of access is received, and then can determine the disk of access needle pair according to interface class.In the embodiment of the present application, after
It is continuous to continue to use above example, specifically: the access for passing through A class interface is received with disk A, disk B receives the visit for passing through B class interface
It asks, disk C is received through the access of C class interface, for disk D receives the access by D class interface, when there is the visit for disk
When asking generation, detection receives the interface class of access, when detecting the interface for receiving access is A class interface, determines to access
For disk A, it can then determine that disk B, disk C and disk D are not received by access within a preset period of time.
The second way: according to the corresponding relationship of the interrupt number of the preset access and disk, from the multiple disk
The middle determination disk for receiving access corresponding with the interrupt number of the access and the first disk for not receiving access.
In the embodiment of the present application, specifically: with preset access interrupt number be 1 when, determine access needle to magnetic
Disk A；When the interrupt number of access is 2, determine access needle to disk B；When being 3 in the interrupt number of access, access needle pair is determined
Disk C；When the interrupt number of access is 4, for determining access needle to disk D.When there is the access for disk to occur, processing
Device detection obtains the interrupt number of access, then true according to the interrupt number detected when the interrupt number for determining access is 1 and 2
It makes disk A within a preset period of time and disk B receives access, so that it is determined that going out disk C and disk D within a preset period of time
It is not received by access.
In the specific implementation process, the uninevitable corresponding relationship of the interrupt number and disk of access, in above-mentioned implementation
Citing only for convenience of understand, the corresponding relationship between interrupt number and disk accessed in the specific application process can be according to reality
Border situation is arbitrarily arranged, here, in the embodiment of the present application with no restrictions.
After executing completion step S102, the method in the embodiment of the present application just executes step S103, it may be assumed that control bus
First output state of expander pin, so that Power Management Unit is based on first output state and cuts off the power and described the
The connection of one disk.
In the embodiment of the present application, specifically: a pin of bus extender respectively corresponds a disk, is determining
When disk is not received by access in preset time period, processor controls the output shape of bus extender pin corresponding with disk
State when Power Management Unit detects the output state of pin, is cut off the power the connection with disk according to the output state of pin.
For example, with the corresponding disk A of the pin 1 of bus extender, the corresponding disk B of pin 2, the corresponding disk C of pin 3, pin 4
Corresponding disk D, the corresponding disk of pin is power-up state when pin is high level output state, and pin is low level output state
When the corresponding disk of pin be power-down state for.When processor detects that disk C within a predetermined period of time and disk D do not connect
When receiving access, the pin 3 and pin 4 for controlling bus extender corresponding with disk C and disk D are low level output state,
At this point, Power Management Unit detect bus extender pin 3 and pin 4 be low level output state when, cutting disk C and
The connection of disk D and power supply.
In the specific implementation process, the output state of bus extender pin and to disk power on or the control of lower electricity between
Uninevitable corresponding relationship, the citing in above-mentioned implementation is only for convenience of understanding, bus extension in the specific application process
The output state of device pin and to disk power on or the control of lower electricity between corresponding relationship can arbitrarily set according to the actual situation
It sets, here, in the embodiment of the present application with no restrictions.
In order to make the disk for being in power-down state receive access after can recover immediately work, the side in the embodiment of the present application
Method can also execute following steps:
The processor detection obtains the second access information for being directed to the multiple disk access；
Based on second access information, the second disk for receiving access is determined；
When the second disk is power-down state, the second disk is waken up.
In the present embodiment, continue to continue to use above example, specifically: after control disk C and disk D power down, after
Continuous detection is determined corresponding with the second access information for the access of multiple disks when having detected the second access information
The disk of access needle pair, when determining access needle to disk C, the pin 3 of processor control bus expander and corresponding disk C
For high level output state, it is high level output that Power Management Unit detection, which obtains bus extender pin 3 corresponding with disk C,
When state, the connection of turn-on power and disk C wakes up disk C and restores to work normally.
