Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Referring to Figure 1, Fig. 1 is that the implementation method of main screen synchronous sharing of the present invention to multiple vice screen curtains is preferably implemented
The flow chart of example.As shown in Figure 1, the main screen synchronous sharing provided in an embodiment of the present invention is to the realization side of multiple vice screen curtains
Method, comprising steps of
Step S100, main screen terminal is measured in real time the instruction of the File Open of specified extension name, when detecting this
File Open then obtains the corresponding file data of desktop present displayed content when instructing；
Step S200, when secondary screen terminal and main screen terminal, which establish Wi-Fi, to be wirelessly connected, then main screen terminal will be literary
Number of packages evidence is sent to secondary screen terminal；
Step S300, secondary screen terminal receives the file data, and shows the file data.
The present invention by Wi-Fi module by the corresponding file data synchronous transfer of main screen terminal present displayed content at most
It is a therewith by the secondary screen terminal of Wi-Fi connection, secondary screen terminal include user it is portable as mobile phone, tablet computer,
The intelligent terminals such as laptop.When secondary screen terminal receives the file data, the file data is restored (as decompressed institute
State file data), and local file identical with file data type is generated, it realizes main screen terminal and user carries
Secondary screen terminal file-sharing, substantially increase the utilization rate of secondary screen terminal as user and understand that conference content provides very
Big help.
It further, include: when main screen terminal detects that preassembled desktop sharing is answered before the step S100
When being started with program, then Wi-Fi Hotspot is opened.Please refer to Fig. 2, the Wi-Fi module in main screen terminal 10 is used as local
Wi-Fi Hotspot, it is each pair screen terminal 20 on Wi-Fi module be then used as local Wi-Fi client, main screen terminal 10 passes through
Local Wi-Fi Hotspot transmits file data that its desktop is shown to multiple vice screen curtain terminals, so that not having broadband Wi-Fi
When network, the data transmission for being also able to achieve high speed is shared, avoids the restriction of Wi-Fi wide area broadband network, that is, does not depend on broadband
Wi-Fi wide area network.
For example, when showing PPT file in the main screen terminal in meeting room, and pass through projector projects to projection screen
On, when main screen terminal detects that the desktop shares application program launching, then main screen terminal program can open main screen
Wi-Fi module in terminal is simultaneously set as Wi-Fi Hotspot Host, and Wi-Fi Hotspot has a default title, such as " PPT_
Share ", user can modify the Wi-Fi Hotspot title in the setting option that the desktop of main screen terminal shares application program, simultaneously
The login password of the settable Wi-Fi Hotspot is set as no password.After being provided with and operate normally of main screen terminal,
The file data currently shown on its desktop is shared away by the Wi-Fi Hotspot of the machine with broadcast mode.
Further, the specified extension name includes document suffix, table suffix, lantern slide suffix and video suffix.Tool
Body, the document suffix includes doc, docx etc., and the table suffix includes xls, xlsx etc., and the lantern slide suffix includes
Ppt, pptx etc., the video suffix include avi, mp4, rm, rmvb etc..Above-mentioned file extension is only used for illustrating, specific real
It applies and is not limited to above-mentioned listed item.
Further, the step S200 is specifically included:
Step S201, secondary screen terminal is shared application program launching to the desktop of user and is detected, when detecting desktop
Then judge whether the Wi-Fi Hotspot searched in specified range when sharing application program launching；
Step S202, Wi-Fi Hotspot column are then obtained when the Wi-Fi Hotspot in vice screen curtain terminal searching to specified range
Table, and established and be wirelessly connected according to Wi-Fi Hotspot corresponding with main screen terminal in Wi-Fi Hotspot list；
Step S203, the corresponding file data of present displayed content is sent to secondary screen terminal by main screen terminal.
The desktop of secondary screen terminal is shared application program and is mounted in secondary screen terminal, when the vice screen curtain terminal operating desktop
When sharing application program, which, which shares application program, can automatically open the Wi-Fi module of secondary screen terminal and actively search for Wi-
Fi hot spot clicks corresponding hotspot name and inputs correct password, through master when searching main screen terminal Wi-Fi Hotspot
Pair screen terminal can establish Wi-Fi connection with main screen terminal after the hot spot of screen terminal is verified.When it is implemented, vice screen
When curtain terminal is less than distance threshold (such as 10-100m) at a distance from main screen terminal, then secondary screen terminal can be with main screen terminal
Establish Wi-Fi connection.
Further, in the step S300 further include: secondary screen terminal carries out the Fileview operational order of user
Real-time detection then carries out file data according to Fileview operational order when detecting the Fileview operational order of user
Corresponding operation.
User is can be in secondary screen terminal as needed to the file data edlin, when it is implemented, such as the text
The type of number of packages evidence is PPT, can be according to the page number number for the synchronous documents that secondary screen terminal receives come organization file data i.e. PPT
The page number sequence of file.Secondary screen terminal is synchronized with main screen terminal and shows under normal circumstances, when vice screen curtain terminal user needs
When read to prevpage or other pages having been displayed, then user's operation is secondary screen terminal according to main screen terminal
The local file of display and generation, in user's Hui Yue file, secondary screen terminal backstage, which still synchronizes, receives main screen terminal
Synchronous documents refresh, and secondary screen terminal can receive simultaneously if main screen terminal has updated the page during secondary screen terminal Hui Yue
It is stored in this document and is browsed with standby user.After the completion of user browses, interface can automatically return to the shape synchronous with main screen terminal
State presses scheduled key and is quickly returning to the state synchronous with main screen terminal current desktop.
As it can be seen that the present invention passes through the file data real-time synchronization that shows main screen terminal and saves to multiple and main screen
Terminal passes through the secondary screen terminal of Wi-Fi connection, and audience is made to can use oneself portable intelligent terminal as vice screen curtain
Terminal shares the file data of main screen terminal, and user is facilitated to grasp the file data that main screen terminal is shared locally
Make.
Based on above method embodiment, the present invention also provides a kind of main screen synchronous sharings to the realization of multiple vice screen curtains
System, as shown in figure 3, the system comprises:
Main screen desktop acquisition module 100 carries out the File Open instruction of specified extension name for main screen terminal real-time
Detection, the corresponding file data of desktop present displayed content is then obtained when detecting this document open instructions；
Sending module 200, for when secondary screen terminal and main screen terminal are established Wi-Fi and are wirelessly connected, then main screen
File data is sent to secondary screen terminal by terminal；
