Hold it is above-mentioned, for the application mode of foregoing WiFi Y-connections, as route WiFi module firmware program, it is necessary to
Support WDS functions.It is well known that WDS (Wireless Distribution System), Chinese is wireless distributed system
System, it is the agreement of two access points (AP) of wireless connection；In whole WDS wireless networks, multiple AP by bridge joint or in
Connected after mode, make whole LAN wirelessly based on.Wherein WDS has repeater mode Repeater and bridge joint
Two kinds of Mode B ridge, the main difference of both of which is：For repeater mode, its information received from a certain access point
Bag can be forwarded to another access point by WDS connections；And bridge mode, its packet received by WDS connections can only
Being forwarded to cable network, (such as by wireless bridging pattern, route WiFi module 251 shown in Fig. 2 will can receive
Packet is forwarded to arm processor 211 through networking PHY chip 212) or wireless host.
In wireless bridging pattern, it is each from control WiFi module itself except Station (client mode) and itself
Original AP (access point) focus, then a virtual AP focus can come out again, with provide can logon web page configuration interface IP,
Can thus solve the problems, such as that being unable to logon web page interface when WiFi module is in wireless bridging pattern is configured.
In order to realize data transfer during WiFi module Y-connection, routeing the firmware program of WiFi module also needs what is supported
Function has：The open and close of DHCP functions, the power-off control operation to routeing WiFi module, to the soft multiple of route WiFi module
The operation such as position, factory reset, and log in the IP configuration features of the WEB configuration interfaces of route WiFi module；Fig. 3 is route
A kind of configuration interface schematic diagram of WiFi module.
It can be clearly seen that in figure 3：Under the configuration interface of route WiFi module, some as shown in Figure 3 be present
Function, by upper computer software, user can set the opening and closing of the DHCP functions of route WiFi module, to realize difference
The demand of user.
Furthermore as shown in figure 3, it can also be realized in the advanced settings options of configuration interface to the soft of route WiFi module
Reset, the operation such as factory reset, mode all notice roads that the two operations are realized by WiFi module the IP that logs in, then
It could be communicated by being realized between HTTP and route WiFi module.The mode of http communication is such as：http://
192.168.10.1/:.wop:Reset, this order is sent to route WiFi module by routeing the LAN mouths of WiFi module,
After route WiFi module receives, reply OK and represent communications setting success.
Another function of the embodiment of the present invention is exactly that the setting that IP is logged in WiFi can be realized by upper computer software, is used
Family can log in IP according to the use environment of oneself, the self-defined setting WiFi of oneself, and the IP of current default is 192.168.10.1
(as shown in Figure 3).
In addition, it is to go to operate by two ways that the power-off restarting of current route WiFi module, which operates, one is and LED
What the power-off restarting of display control program terminal software was set together, break when LED display control programs terminal is set by user
After electricity is restarted, system first can carry out power down process to the system for routeing WiFi module, and then LED display control programs are entered again
Row power down process operates；Another is on configuration interface as shown in Figure 3, can be implemented separately and route WiFi module is broken
Electric reboot operation, to meet the application demand of different occasions.
Setting shown in figure 3 above on configuration interface can only all realize communication under WiFi common route pattern, in nothing
It is that can not realize communication under line bridge mode, user can only be logged in route WiFi module by WEB webpages and web interface is carried out
The operation such as configuration.
It can carry out routeing the switching of WiFi module mode of operation, current WiFi in the WEB interface of route WiFi module
Pattern switching distinguishes two kinds of different modes, and one kind is to switch to wireless bridging pattern from common route pattern：Due to common road
Logged in knowable to IP is user, therefore directly can be handed over by HTTP orders and route WiFi module as the WiFi under pattern
Mutually, realize and common route pattern is switched into wireless bridging pattern；Another kind is from wireless bridging pattern switching to common route
Pattern：Route WiFi module fictionalizes 1 wireless aps focus, dedicated for being arranged to wireless bridging pattern in route WiFi module
When, the standby AP focuses of the route WiFi module are connected for being provided to terminal user, and WEB interface is logged on by it, it is real
Now from wireless bridging pattern switching to the function of common route pattern.
Finally it should be noted that the WiFi Y-connection schemes that the embodiment of the present invention proposes are not limited to cylindrical LED screen,
It is also applied in the production ageing link of LED display control programs.Furthermore the bimodulus LED display control programs shown in Fig. 2
The citing of the LED display control programs of WiFi module is only configured with, it is not used for limiting the present invention, such as it can also be
The LED display control programs for the configuration route WiFi module that can only operate under asynchronous mode are (such as by structure shown in Fig. 3
Video decoding module 240 dispenses).In addition, it is necessary to explanation, using multiple LED display controls systems of WiFi Y-connections
The quantity of system (being each configured with routeing WiFi module) is not limited to five shown in Fig. 1 or other quantity, as long as energy
Ensure it is each from control WiFi module be located in the wireless signal coverage of master control WiFi module.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the technical spirit pair according to the present invention without departing from technical solution of the present invention content
Any simple modification, equivalent change and modification that above example is made, in the range of still falling within technical solution of the present invention.
