Such as, in the above example, the control that one-time continuous pressing signal is corresponding is received in presetting scheduled duration
Signal processed is 00, and control signal corresponding when receiving 1 single depression signal is 01, receives 2 lists
Control signal corresponding during secondary pressing signal is 10, receives control letter corresponding during 3 single depression signals
Number it is 11.
Control chip 160, is used for adding terminal 142 by data and data subtracts terminal 143 and export control signal.
Control chip adds terminal 142 by data and data subtract terminal 143 output voltage, by controlling data
Add terminal 142 and voltage difference that data subtract between terminal 143 is believed to the control exporting binary-coded character form
High level 1 in number and low level 0, when data add terminal 142 and data to subtract the voltage difference of terminal 143 big
In or during equal to voltage threshold, represent the high level 1 in control signal；When data add terminal 142 and data subtract
When the voltage difference of terminal 143 is less than voltage threshold, represent the low level 0 in control signal, voltage threshold by
Systemic presupposition or User Defined.
Control chip binary-coded character serial transmission by turn from low order character to high-order character to control signal,
Such as, voltage threshold is 0.5V, and control signal is 01, then control chip adds terminal output by controlling data
Voltage 2.7V, controls data and subtracts terminal output 2.0V, the voltage difference that data add terminal and data subtract between terminal
Value is that 0.7V is more than voltage threshold 0.5V, i.e. achieves output low order character 1；Control chip is by controlling number
According to adding terminal output voltage 2.3V, controlling data and subtract terminal output 2.0V, data add terminal and data subtract terminal
Between voltage difference be 0.3V, less than voltage threshold 0.5V, i.e. achieve output high-order character 0.
In sum, the USB interface plug that disclosure embodiment provides includes button, USB plug and control core
Sheet, button includes press section and lead-out terminal, and USB plug includes that power supply terminal, data add terminal, data
Subtracting terminal and ground terminal, control chip is connected with the lead-out terminal of button, control chip the most respectively with USB
The power supply terminal of plug, data add terminal, data subtract terminal and are connected with ground terminal；Solve currently used
Interface plug be all plastic cement material, be only capable of the USB interface preventing foreign body from carrying out USB device, utilization rate is relatively low
Problem；Reach USB interface plug and included control chip and circuit connection structure, enter USB device in grafting
Time, can not only prevent foreign body from entering the USB interface of USB device, moreover it is possible to receive button operation and generate control
USB device is controlled by signal, improves the effect of the utilization rate of USB interface plug.

The number of signal processed, generates the control instruction corresponding with the number of control signal.
The corresponding different control instruction of control signal of different numbers, the number of control signal and control instruction
Corresponding relation is systemic presupposition or is preset by USB device by user.Such as, control signal
It is a binary-coded character, in being set in advance in scheduled duration, receives the control of control signal 1 correspondence
Instruction is to take pictures, and receiving control instruction corresponding during two control signals 1,1 in scheduled duration is screenshotss,
Then when USB device receives two control signals 1,1 in scheduled duration, the control generating screenshotss refers to
Order.
Optionally, when receiving control signal, generate the control instruction corresponding with the type of control signal.
The corresponding different control instruction of the type of different control signals, the type of control signal and control instruction
Corresponding relation be systemic presupposition or preset by USB device by user.Such as, letter is controlled
Number being two binary-coded characters, the control instruction of default settings control signal 00 correspondence is to take pictures, control signal
The control instruction of 01 correspondence is screenshotss, and the control instruction of control signal 10 correspondence is to open bluetooth, control signal
The control instruction of 11 correspondences is to open torch, then USB device is when receiving control signal 10, generates and beats
Open the control instruction of bluetooth.
In step 404, USB device performs control instruction.
After USB device equipment performs control instruction, continue executing with the program interrupted before.
In sum, the control method that disclosure embodiment provides, USB device receives USB interface plug and sends
Control signal, generate control instruction perform control instruction according to control signal, reached to beat need not
