Abstract
The utility model relates to a 3G USB flash drive, comprising a CPU processing system for controlling the communication connection of a 3G module, controlling the data transmission of a USB interface and maintaining the storage space of a SD memory, a 3G radio communication module for performing the dialing network connection under the control of a CPU to realize the radio communication and downloading the file on a server in a radio communication mode to a SD card memory in an equipment, a SD storage module for storing the data and transmitting the same to the subscriber equipment when the USB flash drive is connected with the subscriber equipment, and a USB interface for accomplishing the connection of the USB flash drive and the subscriber equipment. According to the utility model, the 3G USB flash drive combines a 3G communication technology, a FLSH storage technology and a USB communication technology, the radio communication, the transmission control, the data receiving and the like are built-in, the data is transmitted to the field directly by using the 3G wireless to be stored on the FLUSH, then the data is used for the subscriber by the USB.
Description
Technical field
The utility model relates to a kind of USB flash disk, particularly a kind of 3G flash disk that can wirelessly transmitting data.
Background technology
Wireless communication technology is a technology that has vigor and potentiality at present most, from the first generation (1G) voice communication, develop into widely used second generation today (2G) and 2.5G voice communications versus data communications, just brought into use the 3G communication technology at present, compare 1G-2.5G, 3G communication has higher transmission speed, estimates also can start the brand-new radio communication epoch.
Radio communication also has shortcomings such as use cost height, utilization structure trouble at present.Such as data transmission, the user need set up data server, needs fixing communication IP, need write server software, writes the Data Receiving process software.In general, all at present used wireless files transmission all be unable to do without computing machine, because need programmed control.
Existing USB flash disk has only the function of storage file, must be connected the transmission that could realize file with computing machine.
The utility model content
The purpose of this utility model is with up-to-date 3G wireless communication technology and ripe FLASH storing technology, the combination of usb bus technology, provides a kind of directly by the 3G flash disk, and with literal, picture, content delivery such as video are to remote client's product.
A kind of 3G flash disk of the utility model comprises: the CPU disposal system, provide one main one from 2 USB interface, described main USB interface is connected with the 3G module, described from USB interface as the external USB interface of equipment.The SD storage interface that CPU provides is connected with the SD storer.Simultaneously, CPU control 3G module communicates to connect the data transmission of control USB interface and the storage area of safeguarding the SD storer.The 3G wireless communication module carries out Dial-up Network and connects under CPU control, realize radio communication, and the mode of the file on the server by radio communication downloaded on the SD card memory in the equipment.The SD memory module is used for storing data, when USB flash disk is connected with subscriber equipment, is transferred to subscriber equipment again.And USB interface, be used for finishing being connected of USB flash disk and subscriber equipment.
The utility model 3G flash disk is with the 3G communication technology, the CPU control technology, the FLSH storing technology, the usb communication technology combines, functions such as radio communication, transmission control, Data Receiving is built-in, directly utilize 3G wireless with data transmission to on-the-spot, be stored on the FLASH, use for the user by USB.The user uses these data no longer to be concerned about wireless transmission, and just with respect to the USB flash disk copied files.
The utility model has following advantage:
1) function is single-minded, uses simple;
2) need not to install any program, plug and play;
3) interface is unified, and use-pattern is unified, and is non-maintaining;
4) use no requirement (NR), can use as long as can read the place of USB flash disk.
Description of drawings
Fig. 1 is the utility model 3G flash disk structured flowchart.
Embodiment
Below, describe in detail in conjunction with the accompanying drawings according to preferred embodiment of the present utility model.
The utility model 3G flash disk main body is Embedded CPU disposal system, more preferably, can adopt the ARM9 system of minimal configuration, master chip ATSM9260T, dispose 2 32M storage chips, 2 32M FLASH chips constitute 64M RAM, the minimum ARM system in 64MFLASH space, draw a USB that chip carries simultaneously from interface, be used for communicating by letter, draw a USB main interface and be used for and 3G communication module interface, simultaneously the SD card of ARM system oneself is drawn with main process equipment.The 3G module can be any 3G module, adopts the EVDO module just to support EVDO, adopts the WCDMA module just to support WCDMA, adopts TDSCDMA just to support TD.With embedded OS on the system loads, hardware just can be connected from interface by USB with computing machine or equipment, and the SD card is exactly the storer of module simultaneously.
During use, write conventional dial-up program, carry out 3G and connect, use http communication protocol access file server, download the file that needs, be stored in the file of SD card appointment, like this file just from downloaded to the 3G flash disk.Controller is controlled USB interface and user's computer or other devices communicatings subsequently, subscriber computer or other equipment just find that the storer of a USB occurs, the file of direct control storer, the file of having downloaded in the storer is directly offered external equipment, and the function of whole 3G flash disk has just realized.
In actual applications, the file transfer that much depended on computer program originally can use this 3G flash disk to realize.Such as: the video ads of ad playing machine upgrades, and can directly plug this 3G flash disk, and self-timing upgrades the video of advertisement machine; The business personnel can directly take out on the computing machine that flash disk is inserted in the client at curstomer`s site, waits a moment, and the file that the client needs, picture, program, quotation waits and has just passed to USB flash disk from company, and this does not need the user to operate; For another example, the software of software company's distribution has not spent site certificate sequence number update program, the user wants refresh routine at every turn, just plugs USB flash disk and directly installs, and arrives up-to-date file and the program of this installation is an auto-update, and pirate user do not have the 3G flash disk, just can not upgrade yet.
Described in this instructions is several preferred embodiment of the present utility model, and above embodiment is only in order to the explanation the technical solution of the utility model but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within scope of the present utility model.
