Specifically, control module includes Interference Detection unit, interference judging unit, WIFI state judging unit and control letter
Number generation unit, after determining and accessing USB3.0 interface from equipment, control module is not carried out to from equipment control module at once
Identification and initialization, but detection, when not being associated from equipment with control module, the communication network of WIFI module has existed
The first noise intensity；After having detected the first noise intensity, control module just to being identified and being initialized from equipment, is detected
Second noise intensity of the communication network of WIFI module.Interfere judging unit according to the first noise intensity and the second noise intensity
Size relation determines from whether equipment generates interference to WIFI module, is determining to generate interference, WIFI to WIFI module from equipment
State judging unit judges that WIFI module is in after receiving state signal, and control signal generation unit generates control signal.It is right
The device that WIFI module generates interference is not necessarily generated by the slave equipment for accessing USB3.0 interface, it may be possible to other equipment
It generates, for example, multiple bluetooth equipments of main equipment where access control module or other communication channels and WIFI module is logical
The equipment closed on of letter channel, the device provided in an embodiment of the present invention for preventing USB3.0 equipment interference WIFI module, from equipment
Carry out data transmission being associated with control module and successively the noise intensity of WIFI module is detected, so that it is determined that WIFI module
Noise intensity whether generated by the slave equipment for accessing USB3.0 interface, when avoiding not interfering the generation of WIFI module from equipment
The data transmission procedure between equipment and control module is interrupted, the high data for further making full use of USB3.0 technology to provide
Transmission rate.

, link state adjustment module adjusts the on-off of data transmission link to control the transmission state of data transmission link, specific packet
First switch unit and second switch unit are included, controls data transmission link and data receives link respectively.
It should be noted that since the device provided in an embodiment of the present invention for preventing USB3.0 equipment interference WIFI module is
The data-transmission interruptions between equipment and control module are controlled by controlling the on off operating mode of data transmission link, from equipment
Data transmission with control module is all respectively carrying out always, only because the disconnection of data transmission link causes both sides to receive not
The data sent to other side, are not control module active break data transmission procedure, thus both sides can inquire respectively
The data packet of loss, WIFI module be in data send state when, can the data packet to loss transmitted again, rather than
Only newly generated data packet is transmitted.
Transmission data packet from equipment is sent to for control module, confirmation data packet can be returned after receiving successfully from equipment
To control module, determination receives successfully from equipment after control module obtains confirmation data packet；For being sent to control mould from equipment
The data packet of block, is the received data packet of control module, and control module can be controlled to from a certain number of data packets of device request
Module may determine whether that whole received data packets are properly received by detecting the quantity of received data packet.Optionally, in order to
Realize the packet retransmission to loss, the transmission data packet write-in of control module sends mark, receives control from equipment
After the transmission data packet of module, the confirmation mark of the confirmation data packet of return identifies identical with corresponding transmission；Control module
Transmission mark, the association corresponding with the data packet that control module is requested of transmission mark is written from equipment in received data packet.It controls as a result,
Molding block can be identified by detection confirmation mark and transmission, it is determined whether have the data packet of loss.
In order to realize the packet retransmission to loss, control module further includes mark recognition unit, data packet detection
Unit and data packet retransmission unit；Wherein, mark recognition unit is used for the confirmation mark to the confirmation data packet sent from equipment
Transmission with transmission data packet is identified；Data packet detecting unit member is used to be identified according to confirmation, detection control module hair
Send the transmission data packet of failure；It is identified according to transmission, detects the received data packet of control module reception failure；Data packet retransmission list
Member is used to send the transmission data packet to fail to from equipment transmission again when WIFI module is in and sends signal condition；Again
Request the received data packet from equipment transmission reception failure.As shown in connection with fig. 3, further, the control module 1 further includes
One link interference detection unit 11 and the first link interference judging unit 12；
The first link interference detection unit 11 is used to interfere in described generate the WIFI module 3 from equipment of judgement

The specific data transmission link for generating interference to WIFI module out can also further allow subsequent link control to be more directed to
Property.
Further, the control signal generation unit 8 is specifically used for:
First noise intensity and the third noise intensity phase are determined in the first link interference judging unit 12
The same and described WIFI module 3 is in after receiving state signal, is generated first switch and is controlled signal；Wherein, the first switch
Control signal disconnects and controls the second switch unit closure for controlling the first switch unit；
First noise intensity and the 4th noise intensity phase are determined in the first link interference judging unit 12
The same and described WIFI module 3 is in after receiving state signal, is generated second switch and is controlled signal；Wherein, the second switch
Control signal is disconnected for controlling the first switch unit closure and controlling the second switch unit；
Determine that the third noise intensity and the 4th noise intensity are equal in the first link interference judging unit 12
The not identical and described WIFI module 3 is in after receiving state signal with first noise intensity, generates third switch control
Signal；Wherein, the third switch control signal is disconnected for controlling the first switch unit and the second switch unit
It opens.
Specifically, by the first link interference detection unit and the first link interference judging unit it can be concluded that WIFI mould
After block generates the specific link of interference, control module generate corresponding control signal to generate the data transmission link of interference into
The adjustment of row transmission state, continues to tend to remain on to the data transmission link for not generating interference.Specifically, if generating interference
Only data transmission link, control signal generation unit generate first switch control signal, control first switch unit disconnect with
Avoid the communication of WIFI module impacted, second switch unit is connected so that the data transmitted on the link are completely received；
If generating the only data receiver link of interference, control signal generation unit generates second switch and controls signal, and control second is opened
It is impacted to avoid the communication of WIFI module to close unit disconnection, the conducting of first switch unit is so that the data transmitted on the link
It is completely received；If generating not only including data receiver link but also including data transmission link for interference, signal generation unit is controlled
