1) dock by hardware the agreement that 1 GPIO mouth realizes separately a communication, pattern is switched;
2) the factory reset button (being such as positioned on the radio communication daughter board 35 shown in Fig. 3) by route WiFi module carries out multiplexing functions, by the length of button by short by time realize switching;
3) because the MAC Address of other modules (or being referred to as LED display control module) in route WiFi module and LED display control program is unique, therefore also can set up corresponding communication protocol implementation pattern in MAC layer to switch, but this kind of mode implements relatively complicated.
As shown in Figure 4, the operation such as WiFi warm reset, WiFi factory reset can also be realized in the advanced settings options of configuration interface, 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.
The another one 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 4).
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 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 module; Another one is on configuration interface as shown in Figure 4, can realize separately operating the power-off restarting of route WiFi module, with the application demand of satisfied different occasion.
In sum, previous embodiment of the present invention can reach following one or more beneficial effect: a) can by the radio communication between the LED display control program of WiFi serial connection realization configuration route WiFi module; B) compared with pure 3G application scheme, flow cost can be saved; And c) hardware environment building method is comparatively simple, drops into, whole system structure composed advantage of lower cost without the need to wired cost.In addition, be understandable that, the core board 31 shown in Fig. 3, base plate 33 also can be incorporated into same circuit board with each element on radio communication daughter board 35 but not be divided on the different circuit board of polylith.
Finally it should be noted that, the WiFi that the embodiment of the present invention proposes is connected in series scheme and is not limited to multiple lamp stand LED screen, and it is suitable for the LED display of other types equally, as long as its LED display control program connected is configured with route WiFi module.Moreover, bimodulus LED display control program shown in Fig. 3 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 340 in structure shown in Fig. 3) of the configuration route WiFi module that can only work in asynchronous mode.
