Hold above-mentioned, for the application mode of aforementioned WiFi Y-connection, as the firmware program of route WiFi module, need to support WDS function.As everyone knows, WDS (WirelessDistributionSystem), Chinese is wireless distribution system, and it is the agreement of wireless connections two access points (AP); In whole WDS wireless network, multiple AP is coupled together by bridge joint or trunking scheme, make whole LAN be main wirelessly.Wherein WDS has repeater mode Repeater and bridge mode Bridge two kinds, and the main difference point of two kinds of patterns is: for repeater mode, and its packets of information received from a certain access point can be forwarded to another access point by WDS connection; And bridge mode, it connects by WDS the packets of information received can only be forwarded to cable network (such as by wireless bridging pattern, the packets of information received can be forwarded to arm processor 211 through networking PHY chip 212 by the route WiFi module 251 shown in Fig. 2) or wireless host.
When wireless bridging pattern, each is from controlling WiFi module self except Station (client mode) and original AP (access point) focus of self, then can a virtual AP focus be out again, can the IP of logon web page configuration interface to provide, so just can solve when WiFi module is in wireless bridging pattern can not the problem that is configured of logon web page interface.
In order to realize the data transmission during Y-connection of WiFi module, the firmware program of route WiFi module also needs the function supported to have: the open and close of DHCP function, to the power-off control operation of route WiFi module, to the warm reset of route WiFi module, the operations such as factory reset, and the IP configuration feature of WEB configuration interface logging in route WiFi module; Fig. 3 is a kind of configuration interface schematic diagram of route WiFi module.
Can be clearly seen that in figure 3: under the configuration interface of route WiFi module, there are some functions as shown in Figure 3, by upper computer software, user can arrange the opening and closing of the DHCP function of route WiFi module, to realize the demand of different user.
Moreover, as shown in Figure 3, the warm reset to route WiFi module can also be realized in the advanced settings options of configuration interface, the operations such as factory reset, the mode that these two operations realize all must know that road logs in IP, then just by realizing between HTTP with route WiFi module communicating by WiFi module.The mode of http communication as: http: // 192.168.10.1/:.wop:reset, this order is sent to route WiFi module by the LAN mouth of route WiFi module, after route WiFi module receives, replys OK and namely represent communications setting success.
Another function of the embodiment of the present invention is exactly the setting realizing logging in WiFi IP by upper computer software, user can according to the environment for use of oneself, the self-defined WiFi arranging oneself logs in IP, and the IP of current default is 192.168.10.1 (as shown in Figure 3).
In addition, the power-off restarting operation of current route WiFi module goes operation by two kinds of modes, one is be set together with the power-off restarting of LED display control program terminal software, after LED display control program terminal is arranged power-off restarting by user, system first can carry out power down process to the system of route WiFi module, and then carries out power down process operation to LED display control program; Another one is on configuration interface as shown in Figure 3, can realize separately operating the power-off restarting of route WiFi module, with the application demand of satisfied different occasion.
Setting on configuration interface shown in above Fig. 3 all can only realize communication under the common route pattern of WiFi, is to realize communication under wireless bridging pattern, and user can only log in route WiFi module to operations such as web interface are configured by WEB webpage.
The switching of route WiFi module work pattern can be carried out in the WEB interface of route WiFi module, current WiFi pattern switches the different mode of differentiation two kinds, one switches to wireless bridging pattern from common route pattern: be user because common WiFi in routing mode logs in IP, therefore can directly be undertaken alternately by HTTP order and route WiFi module, realize common route pattern to switch to wireless bridging pattern; Another kind is switched to common route pattern from wireless bridging pattern: route WiFi module fictionalizes 1 wireless aps focus, be specifically designed to when route WiFi module installation is wireless bridging pattern, for providing the AP focus for subsequent use connecting this route WiFi module to terminal user, and log on WEB interface by it, realize the function switching to common route pattern from wireless bridging pattern.
Finally it should be noted that, the WiFi Y-connection scheme that the embodiment of the present invention proposes is not limited to cylindrical LED screen, can also be applied in the production ageing link of LED display control program.Moreover, bimodulus LED display control program shown in Fig. 2 is only the citing of the LED display control program being configured with WiFi module, it is not used for limiting the present invention, and such as it also can be the LED display control program (such as being dispensed by the Video decoding module 240 in structure shown in Fig. 3) of the configuration route WiFi module that can only work in asynchronous mode.In addition, it should be noted that, the quantity of multiple LED display control programs (being configured with route WiFi module respectively) of WiFi Y-connection is adopted to be not limited to five shown in Fig. 1, also can be other quantity, as long as can ensure that each is positioned at the wireless signal coverage of master control WiFi module from control WiFi module.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
