Detailed description of the invention
Full-color LED display screen control system disclosed in this utility model is a kind of low cost, high data rate, high flexibility system.Full-color LED display screen control system based on WIFI is a kind of framework based on C/S, and C/S framework is a kind of typical two-tier system, i.e. client and service end.When full-color LED display screen control system is as C/S framework, client is that one or more operates in a kind of human-computer interaction interface on the equipment such as PC, mobile phone, PAD, and server is a kind of service end unit communicated with client by Socket.WIFI medium of communication as client and service end in full-color LED display screen control system serves a bridge beam action.
In order to make the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and this utility model is described further by detailed description of the invention.
As depicted in figs. 1 and 2, this utility model provides a kind of full-color LED display screen control system, it includes client 1, wireless module 2, Date Conversion Unit 3 and service end 4, and client 1 is for being configured to control card or obtain control card state or to controlling holding firmware upgrading etc..
Client 1 is sent data to Date Conversion Unit 3 by wireless module 2, after data being identified and change by Date Conversion Unit 3, it is sent to service end 4 again by wireless module 2, data are resolved by service end 4, and then control to have blocked corresponding operation, such as control perhaps to feed back client in LED display is play and currently control the state of card.Wherein, service end 4 is provided with command analysis module 41, this command analysis module 41 is for resolving the data that client 1 sends, what i.e. client 1 was sent by service end 4 is used for setting or obtains the control instruction that data parsing is control card controlling card state or upgrading control holding firmware, makes control card according to the instruction corresponding action of execution.
Date Conversion Unit 3 includes encrypting-decrypting module 31, authentication module 33, key management module 34 and data conversion module 32.Encrypting-decrypting module 31 receives the data of wireless module 2 transmission and data is encrypted/decryption processing；After data are processed by encrypting-decrypting module 31, it is sent directly to data conversion module 32 or sends to data conversion module 32 after authentication module 33 certification and key manage module 34 management.Encrypting-decrypting module 31 and authentication module 33, key management transmit data by mac-layer protocol between module 34, data conversion module 32.
The wireless module 2 of the present embodiment and service end 4 are arranged on the control card of LED display, and wireless module 2 is as the medium of communication between client 1 and service end 4, and this medium of communication is realized by RLT8188 WIFI module；Service end is for storing and process the data that client sends, and then resolves to the control instruction controlling card, in order to controls card and performs corresponding action according to control instruction.
For medium of communication RTL8188 WIFI module, it supports ap mode, STA mode, and transfer rate can reach 150Mbps, and transmission range can reach more than 30 meters.When RTL8188 WIFI module as ap mode when, client 1 carries out data exchange by connecting this focus and service end 4.When RTL8188 WIFI module as STA mode when, service end 4 is connected to wireless router by WIFI module and is connected to the client 1 of wireless router and carries out data exchange.
Principle when client 1 is connected to the focus of RTL8188 WIFI module and service end 4 carries out data interaction:
Client 1 sends an information frame, and information frame arrives first at the radio physical layer interface of AP and is then submitted to encrypting-decrypting module 31, and AP judges that the type of information frame is Frame or management frame.If Frame, then get to data conversion module 32 by the transmission of MAC layer association；If management frame, then it is sent to authentication module 33 and key management module 34 by mac-layer protocol, authentication module 33 and key management module 34 are authenticated according to the information provided in management frame, connect or after the operation such as handover, it is sent to data conversion module 32 and carries out data conversion, and provide feedback information (success or failure) to client 1.
Service end 4 is built STA mode by RTL8188 WIFI module and is connected to wireless router and is connected to the client 1 of wireless router and carries out data exchange, now client 1 and server are all in the same LAN built by wireless router, the principle of the exchange of data:
First ARP cache(cache can be searched for when client 1 sends message) purpose IP is mated, if the match is successful, ARP(address resolution protocol) IP address correspondence MAC Address will be returned to the application program continuation encapsulation of client 1, if it fails to match, can initiate an ARP request, ARP request is broadcast on LAN each equipment.If there being the service end 4 that purpose IP is corresponding in LAN, then service end 4 can return the MAC Address of oneself to the client 1 initiating ARP request.Now client 1 application program continuation encapsulated message is subsequently sent to wireless router, router can judge after receiving message that whether client 1 and server are at same LAN, if being just by two layers of forwarding at same LAN, three layers of forwarding otherwise will be carried out.
Finally should be noted that; above example is only in order to illustrate the technical solution of the utility model; rather than the restriction to this utility model protection domain; although having made to explain to this utility model with reference to preferred embodiment; it will be understood by those within the art that; the technical solution of the utility model is modified or equivalent, all belong to protection domain of the present utility model.
