Number when, the second end of the 3rd controlled switch 106 is connected with first end, in the 3rd controlled switch 106
The 3rd end when obtaining cut-off signal, the second end of the 3rd controlled switch 106 and first end disconnect.
When the first usb 1 01 is connected with the USB interface of measured terminal 200, and the 2nd USB
When interface 102 is connected with the USB interface of calculation machine 300, calculation machine 300 can be to quilt
Survey terminal 200 and carry out USB interface test, wherein USB interface test includes resting state test
With non-sleep state test.Setting up between calculation machine 300 and measured terminal 200 has USB
During data cube computation, measured terminal 200 can not enter resting state, therefore can not carry out resting state survey
Examination, can only carry out non-sleep state test.
When calculation machine 300 will carry out non-sleep state test to measured terminal 200, pass through
Data wire 120 sends the first switching command, switching control module 103 to switching control module 103
Receive the first switching command that calculation machine 300 sends, and produced even according to the first switching command
Messenger is to control between the first usb 1 01 and the corresponding pin of secondary USB interface 102
Connection.
When calculation machine 300 will carry out resting state test to measured terminal 200, by number
Send the second switching command according to line 120 to switching control module 103, switching control module 103 connects
The second switching command that Acceptance Tests computer 300 sends, and disconnection is produced according to the second switching command
Signal is to control the interruption of the first usb 1 01 and the corresponding pin of secondary USB interface 102
Open.
Specifically, when switching control module 103 produces communications signals, this communications signals is respectively
Input to the 3rd end of the first controlled switch 104, the 3rd end of the second controlled switch 105 and
3rd end of three controlled switch 106 is so that the first end of the first controlled switch 104 and the second end connect
The logical, first end of the second controlled switch 105 connects with the second end, the of the 3rd controlled switch 106
One end connects with the second end.So that the VBUS pin and second of the first usb 1 01
The VBUS pin connection of usb 1 02, the D+ pin and second of the first usb 1 01
The D+ pin connection of usb 1 02, the D- pin of the first usb 1 01 and the 2nd USB
The D- pin connection of interface 102.Now set up between calculation machine 300 and measured terminal 200
Usb data connects, and calculation machine 300 can send to measured terminal 200 or receive USB number
According to so that measured terminal 200 can carry out non-sleep state test.
When switching control module 103 produces cut-off signal, this cut-off signal is separately input into first
3rd end of controlled switch 104, the 3rd end of the second controlled switch 105 and the 3rd controlled switch
106 the 3rd end is so that the first end of the first controlled switch 104 and the second end disconnect, second is subject to
The first end of control switch 105 and the disconnection of the second end, the first end and second of the 3rd controlled switch 106
End disconnects so that the VBUS pin of the first usb 1 01 and secondary USB interface 102
The disconnection of VBUS pin, the D+ pin of the first usb 1 01 and secondary USB interface 102
D+ pin disconnect, the D- pin of the first usb 1 01 and secondary USB interface 102
D- pin disconnects.Now it is not set up USB between calculation machine 300 and measured terminal 200
Data cube computation is so that measured terminal 200 can carry out resting state test.
Wherein, during measured terminal 200 carries out resting state test, calculation machine 300 can
The setting time delay corresponding time, specifically can be after calculation machine 300 sends the second switching command
Counted, during counting, calculation machine 300 will not be attempted entering with measured terminal 200 at once
Row usb communication.
Measured terminal 200 can carry out resting state test by running resting state test script,
And this resting state test script can be logical before sending the second switching command by calculation machine 300
In the usb data linkup transmit set up before this to measured terminal 200.
After the completion of resting state test, calculation machine 300 can be by data wire 120 to switching
Control module 103 sends the first switching command so that calculation machine 300 and measured terminal 200
Re-establish usb data to connect, calculation machine 300 is connected from tested end by usb data
End 200 acquisition resting state test result.
In the present embodiment, due to setting up USB between calculation machine 300 and measured terminal 200
During data cube computation, measured terminal 200 can not enter resting state, thus resting state can not be completed
Test, therefore the device automatically controlling USB cable break-make of the present invention is arranged on calculation machine 300
And measured terminal 200 between, when measured terminal 200 need to carry out resting state test, this device
Produce cut-off signal by obtaining the second switching command from calculation machine 300, and according to disconnection
Signal controls controlled switch to disconnect the usb data between measured terminal 200 and calculation machine 300
Connect, so that measured terminal 200 can enter resting state, to complete resting state test.
In the present embodiment, calculation machine 300 can provide the corresponding controlling interface with instruction user to be
No measured terminal 200 is carried out non-sleep state test or resting state test.It is right to select in user
When measured terminal 200 carries out non-sleep state test, the corresponding generation first of calculation machine 300 is cut
Change order, when user selects measured terminal 200 is carried out resting state test, calculation machine
300 corresponding generation the second switching commands.
Therefore in the present embodiment, when measured terminal 200 carries out resting state test, achievable quilt
Survey the USB pin docking between terminal 200 and calculation machine 300 automatically to disconnect, need not be artificial
Operation, thus drastically increase testing efficiency.
