Step S301：The default binding catalogue and device path are read from the specified file.
Electronic equipment can be connected computer, with logical by the present embodiment when carrying out electronic equipment interfaces test by serial ports
Cross the test information that correlation was checked or printed to serial ports, such as test equipment designation number, testing time, writing speed, reading speed
Spend and be successfully tested failure information etc..
Step S302：Confirm that the External memory equipment whether there is.
Wherein, when the default binding catalogue and device path can be read in step S301, determine that the outside is deposited
Store up equipment to exist, continue follow-up writing speed and reading speed test；Catalogue and set when the default binding can not be read
During standby path, determine that the External memory equipment is not present, perform step S310 and directly export the test that detection device is not present
Failure information, the information of dependence test failure is exported or printed by serial ports of computers.
Step S303：The NUL stream file of default file size is write simultaneously to the default binding catalogue by dd orders
Record the beginning and ending time.
Step S304：Writing speed is calculated according to the default file size of the NUL stream file and beginning and ending time.
So, in step S303 and step S304, size and the time of write-in file data are copied according to dd orders, very
The writing speed of the interface of the electronic equipment is easily calculated.
Step S305：Whether the writing speed that judgement detects is up to standard.
Wherein, also it is not quite similar for different types of electronic equipment interfaces, the standard of writing speed.In the present embodiment
In, then continue the test of follow-up reading speed when writing speed is up to standard, step S310 is performed when writing speed is not up to standard
Writing speed and test crash information are directly exported, exports or print related writing speed and test crash by serial ports of computers
Information.
Step S306：The data file and note of default file size are read in the default binding catalogue by dd orders
Record the beginning and ending time.
Step S307：Reading speed is calculated according to the default file size of the data file and beginning and ending time.
So, in step S306 and step S307, size and the time for reading file data are copied according to dd orders, very
The reading speed of the interface of the electronic equipment is easily calculated.
Step S308：Whether the reading speed that judgement detects is up to standard.
Wherein, also it is not quite similar for different types of electronic equipment interfaces, the standard of reading speed.In the present embodiment
In, when reading speed is not up to standard, execution step S310 directly exports writing speed, reading speed and test crash information, passes through
Serial ports of computers exports or printed the information of related writing speed, reading speed and test crash.
Step S309：When the reading speed is up to standard, writing speed, the reading speed of the electronic equipment interfaces are exported
With dependence test successful information.

Standby partition table and device node, and obtain the file system format of each subregion.
The binding processing unit 1022 includes zoned format judging unit 10221 and selection binding unit 10222, is used for
The system format select command of the partitioned file read according to the hot plug processing unit 1021 binds the equipment section
Point binds catalogue to default.The zoned format judging unit 10221, for judge the partitioned file system format whether
For new technology file system.The selection binding unit 10222, described in judging when the zoned format judging unit 10221
When the system format of partitioned file is new technology file system, device node described in ntfs-3g command bindings is selected to default binding
Catalogue, and when the zoned format judging unit 10221 judges the system format of the partitioned file not for NTFS files
During system, device node described in mount command bindings is selected to default binding catalogue.Wherein, the default binding catalogue is interior
Core automatically create with zone name identical catalogue, the equipment is bound according to the system format select command of the partitioned file
Node binds catalogue to default.
The storage unit 103, for the default binding catalogue and device path to be saved in specified file.So
The External memory equipment detected is tied to default binding catalogue by the binding unit 102 by hot plug mechanism, and electronics is set
It is standby can be by reading the default binding catalogue and device path in the specified file, to the external storage of access
Equipment carries out follow-up reading by the read or write speed detection unit 105 and write-in is tested.
The confirmation unit 104, for read from the specified file it is described it is default binding catalogue and device path with
Confirm that the External memory equipment whether there is.The present embodiment can lead to electronic equipment when carrying out electronic equipment interfaces test
Serial ports connection computer is crossed, so that the test information of correlation, such as test equipment designation number, test are checked or printed by serial ports
Time, writing speed, reading speed and it is successfully tested failure information etc..The confirmation unit 104 reads the default binding
When catalogue and device path, determine that the External memory equipment is present, row write can be entered subsequently through read or write speed test cell 105
Enter speed and reading speed test；When the confirmation unit 104 can not read the default binding catalogue and device path,
Determine that the External memory equipment is not present, then the test crash information that directly output detection device is not present, pass through computer
Serial ports exports or the information of printing dependence test failure.
The read or write speed detection unit 105, for confirming that the External memory equipment confirms when the confirmation unit 104
In the presence of, the writing speed and reading speed of the electronic equipment interfaces are detected by sense command.Fig. 6 is real for the present invention second
