Into another playback equipment.In use, will be connect with screen transmitter output interface in equipment input interface to be shown,
(for example, by using HDM interfaces).Transmitter should carry an APP.It will be inserted into screen device and show (such as computer, electricity in the display equipment
Depending on machine etc.).Mobile phone setting -- display -- Wireless Display is opened, searches the equipment, it can be with screen in connection.With screen device mesh
In the preceding family for being widely used in people, work.But there is also certain deficiencies for traditional wireless same screen device, i.e., it is traditional
Same screen device do not have the function of networking in itself, the AP hot spots launched are not networked, and user is upper with screen using mobile phone connection
Device can cause mobile phone to disconnect network.For example, see Patent No.：201620232065.3 Chinese utility model patent explanation,
Disclose it is a kind of with screen device, the technical solution used for：Including：Main control unit, radio receiving unit, data processing unit
And data outputting unit, further include the serial ports control unit for controlling output equipment.The technical solution is the basic technology with screen device,
There is no the functions of solving not networking in itself with screen device for it.In addition, see that number of patent application is：201610077632.7 China
Application for a patent for invention prospectus, it discloses a kind of with screen method and terminal.The technical solution is also without solution with screen
The function that device can not network in itself.
Invention content：
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of wired with screen with wireless router
Device, this also has radio router function with screen device.
In order to solve the above-mentioned technical problem, present invention employs following technical proposals：A kind of having with wireless router
Line is with shielding device, including main control unit, this with screen device further include the wired network interface being connect with main control unit, network receiver,
Power interface, storage unit, video output interface, audio output interface and wireless transmission unit；The cable network connects
Mouth receives the data of network transmission, and network data transmission will be received to main control unit, and through master control by network receiver
Wireless transmission unit is transmitted data to after cell translation.
Furthermore, in above-mentioned technical proposal, the power interface uses the Micro USB type interfaces of 5V/2A, leads to
The power interface is crossed to power to main control unit.
Furthermore, in above-mentioned technical proposal, the wired network interface uses RJ45 interfaces, which passes through
One network receiver is connect with main control unit.

Furthermore, in above-mentioned technical proposal, this is additionally provided with button with screen device, which connect with main control unit.
Furthermore, in above-mentioned technical proposal, the storage unit includes the DDR for storing data during program operation
With the flash for store code.
Furthermore, in above-mentioned technical proposal, the main control unit includes video decoding unit and audio decoding unit.
Furthermore, in above-mentioned technical proposal, the CPU includes video decoding unit and audio decoding unit, described
Video decoding unit receives video data and carries out video decoding, is subsequently sent to HDMI/VGA interface output signals, the sound
Frequency decoding unit receives audio data and carries out audio decoder, is subsequently sent to the audio output interface output signal.
Present invention can apply to the mobile terminal devices such as mobile phone, tablet, not only have the function of existing same screen device, simultaneously
The present invention also has a wireless routing function, is to connect with not needed to after shielding device using advantage by the way of wired network interface in the present invention
Other operations can directly surf the Internet, and a wireless router can be equivalent in the same screen device free time and is used.
Description of the drawings：
Fig. 1 is the circuit structure diagram of the same screen device of the present invention
Specific embodiment：
The embodiment of the present invention is further illustrated with reference to specific embodiments and the drawings.
