Description

A kind of wireless system for transmitting data

Technical field

The utility model relates to the radio transmission techniques field, especially a kind of wireless system for transmitting data based on bluetooth and wifi/wapi (Wireless Fidelity/WLAN Authentication and Privacy Infrastructure) technology.

Background technology

Existing bluetooth (BT) technology has been widely used in various electronic, becomes one of standard configuration on mobile communication equipment substantially, by file-sharing between the bluetooth realization mobile device and transmission mutually.Simple, convenient owing to having, Bluetooth technology is along with universal the obtaining of mobile communication equipment used fast and widely, and the mobile phone of the nearly all support bluetooth of Chinese market can both carry out the transmission of bluetooth file.

At present, the not practical application as yet of bluetooth 3.0 standards, bluetooth 2.1+EDR transmission rate theoretical peak is 3Mbps.Be subject to Bluetooth technology itself, hardware interface, memory read write operation and bluetooth drive all multifactor influences such as optimization, and the Bluetooth transmission file speed of mobile phone only is about 60-100kB/s at present.In the big file of transmission, can't meet the demands.Make a general survey of the wireless files transfer function of mobile phone on the market, still adopt the mode of bluetooth OPP and File Transfer Protocol basically, transmission rate is slow, and once can only send a file.

Along with the device end that has the wifi/wapi function at present is more and more, there is scheme to propose to utilize wifi/wapi to carry out the high-speed transfer of two equipment rooms, implemented two steps, one: set up network, two: seek network, transmitting software.The method of performing step one has two kinds: one, two equipment connect common wireless aps (wireless access node or local area network (LAN)) respectively, make two equipment be in consolidated network.Two, utilize the adhoc technology of wifi/wapi to set up adhoc network (being called multi-hop wireless network again), the step operation of this type of networking is trouble very.The software of performing step two all is flying pigeon and ftp etc. generally, and the operation of transmitting software is more loaded down with trivial details and mixed and disorderly, and needs two equipment to move corresponding software simultaneously.This shows that existing wifi/wapi high speed data transfer implements following problem: one, traditional BT transmits, and speed slow excessively (having only about 60-100Kb/s) can only be transmitted very little file.Two, utilize the wifi/wapi transmission, condition is too harsh, and setting operation is too complicated, adds the transmitting software variation, makes that build bad border of transmission bothers very much, and can not initiatively find other equipment in equipment end.

The utility model content

The purpose of this utility model provides a kind of wireless system for transmitting data based on bluetooth and wifi/wapi technology.

The purpose of this utility model is achieved by the following technical solution:

Wireless system for transmitting data, comprise WLAN (wireless local area network) and two or more data communication equipments, wherein each data communication equipment comprises main circuit board, CPU, memory cell and the wireless signal transceiver module that power supply is connected with mutual circuit, described wireless signal transceiver module comprises bluetooth module and wifi/wapi module, bluetooth module comprises Bluetooth chip and the Bluetooth antenna that mutual circuit connects, and the wifi/wapi module comprises wifi/wapi chip and the wifi/wapi antenna that mutual circuit connects;

Described two or more data communication equipments are set up signal connection and transmission data by bluetooth module;

Perhaps, two or more data communication equipments are set up signal by bluetooth module and are connected, by WLAN (wireless local area network) and wifi/wapi module transmission data.

As optimal technical scheme of the present utility model, described data communication equipment comprises mobile phone, PDA or notebook computer.

The beneficial effects of the utility model are: with respect to prior art, the utility model adopts BT+wifi/wapi to carry out transfer of data, equipment end can be by the equipment around the BT search, after searching, can dispose complicated adhoc configuration automatically by BT, finally carry out high speed data transfer by wifi/wapi.

The utlity model has following advantage: 1, simple, mode of operation remains the Bluetooth transmission mode, utilize wifi/wapi and adhoc to carry out complexity with respect to traditional third party software and be provided with, use easier, the more convenient operation of BT-wifi/wapi transmission means.2, quick, conventional mobile phone generally can only once transmit a file, and the utility model can any a plurality of files of disposable transmission, for example transmit a large amount of pictures, song or phone directory etc. simultaneously.3, quick, the highest 1MB/s that surpasses of BT+wifi/wapi transmission rate also more than 800kB/s, is about 10 times of general mobile phone generally, has improved the practicality of mobile phone wireless transfer files greatly.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is the flow chart of the utility model client;

Fig. 2 is the flow chart of the utility model server end.

Embodiment

As depicted in figs. 1 and 2, wireless system for transmitting data, comprise WLAN (wireless local area network) and two above data communication equipments, wherein each data communication equipment comprises main circuit board, CPU, memory cell and the wireless signal transceiver module that power supply is connected with mutual circuit, described wireless signal transceiver module comprises bluetooth module and wifi/wapi module, bluetooth module comprises Bluetooth chip and the Bluetooth antenna that mutual circuit connects, and the wifi/wapi module comprises wifi/wapi chip and the wifi/wapi antenna that mutual circuit connects; Described two or more data communication equipments are set up signal connection and transmission data by bluetooth module; Perhaps, two or more data communication equipments are set up signal by bluetooth module and are connected, by WLAN (wireless local area network) and wifi/wapi module transmission data.In the present embodiment, described data communication equipment comprises mobile phone, PDA or notebook computer.
