Description
Technical field
The present invention relates to a kind of device that utilizes file in the cell phone managing USB flash disk, relate in particular to a kind of device that utilizes mobile phone USB Host (host side) function and switching cable directly to read the USB flash disk file.The invention still further relates to the method for utilizing file in the cell phone managing USB flash disk.
Background technology
The MP3 mobile phone of current trend generally is with jumbo NAND type flash memory (NANDFLASH) in all, perhaps with the function of extrapolation storage card (MEMORY CARD), can support to store the song of how first MP3 format.The mobile holder of popular in the market USB interface has also that capacity is big, the advantage of highly versatile.But the USB interface of mobile phone of not utilizing the mobile phone of present stage realizes the external USB flash disk of mobile phone, and play-overs the function of song in the USB flash disk.Existing other relevant patent is supported external USB flash disk, but all needs just can play the file copy in the USB flash disk to this machine.
The mobile phone of present stage is basically all with the Mini-USB Header connector (micro USB male connector) of slave controller (slave controller) function and the standard of USB1.1, switch by the switch on hardware circuit and the software design, can finish initial password by micro USB Header connector and download (code download), realize in the development process Debug trace, charging and with functions such as the transfer of data of calculator is synchronous, transmit data but all can not be connected with the USB slave (USB slave devices) of outside.
USB-OTG (USB On-The-Go) technology is the technology that developed recently gets up, the role that it is defined as various device " host side ", " equipment end " or has dual identity as required, thereby realization direct connection each other.But this function is based upon on USB 2.0 bases, also to receive relevant mandate expense in addition and on USB 2.0 bases, add the USB-OTG function, present mobile phone all is the low-speed device of USB 1.1 standards, so the present invention is an economical plan before support USB-OTG scheme is arrived in the complete upgrading of the USB of mobile phone socket.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and a kind of device that utilizes file in the cell phone managing USB flash disk is provided, and it will have mobile phone and a USB switching cable of USB HOST function and realize directly reading the USB flash disk file.For this reason, the present invention also will provide a kind of method of utilizing file in the cell phone managing USB flash disk.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of device that utilizes file in the cell phone managing USB flash disk, comprise usb host end module, USB slave module, power module, it also comprises: analog switch module, micro USB Socket connector modules and switching cable, described analog switch module is connected with usb host end module, USB slave module, micro USB Socket connector modules and power module respectively, switches mutually with the path of realization USB subordinate end equipment and the path of usb host end equipment.
A kind of method of utilizing file in the cell phone managing USB flash disk, the mobile phone in this method have USB subordinate end and usb host end interface, comprise the steps:
(1) is provided with the analog switch module before the USB interface of cell phone mainboard circuit, be arranged to use the pattern of USB flash disk when mobile phone interface, described analog switch module switches to the path of usb host end equipment, be arranged to accept the pattern of computer when mobile phone interface, described analog switch module switches to the path of USB subordinate end equipment;
(2) mobile phone interface is arranged to use the pattern of USB flash disk;
(3) end of switching cable connects mobile phone, and the other end connects USB flash disk, docks with the turnover data flow of USB flash disk with the turnover data flow that realizes mobile phone usb host end;
(4) utilize the management tool of mobile phone that the file in the USB flash disk is managed.
The device and method that utilizes file in the cell phone managing USB flash disk of the present invention, the mobile phone and a USB switching cable that only need have the USBHOST function with two MINI-USB Socket Connector (micro USB female connector), just can realize directly reading the function of USB flash disk file, also can revise the setting of embedded in mobile phone MP3 player software simultaneously, the file path that makes the user can select MP3 to play, the present invention also support to duplicate, delete or the USB flash disk of renaming in file.
Description of drawings

Fig. 2 is a switching cable schematic diagram of the present invention.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment.
Present stage, the baseband chip or the Backend IC (rear end picture processing chip) of some middle and high end mobile phones can have USB slave (USB subordinate end) and USB host (usb host end) function, all were the low speed controllers (controller) that meets USB 1.1 versions.USB host port generally is used for and inner other IC (integrated circuit) communications of mobile phone white mourning dress data flow, as and bluetoothIC (bluetooth IC) etc., and now common Bluetooth IC uses UART (UART Universal Asynchronous Receiver Transmitter) interface and goes communication, the speed of general UART port is enough, so USB Host can vacate.
As shown in Figure 1, the present invention utilizes the device of file in the cell phone managing USB flash disk to comprise: usb host end module, USB slave module, power module, also comprise: analog switch module, micro USB Socket connector modules and switching cable, described analog switch module is connected with usb host end module, USB slave module, micro USB Socket connector modules and power module respectively, switches mutually with the path of realization USB subordinate end equipment and the path of usb host end equipment.
Described switching cable, the one end is provided with USB Header connector, the other end is provided with the USBSocket connector, described USB Header connector is connected with mobile phone, described USB Socket connector is connected with USB flash disk, dock with the turnover data flow of USB flash disk with the turnover data flow that realizes mobile phone usb host end, provide the voltage (see figure 2) by battery of mobile phone.
Be arranged to use the pattern of USB flash disk when mobile phone interface, described analog switch module switches to the path of usb host end equipment, when if the port of software control USB device (USB Devices Enablecontrolled by software) detects the available signal of USB flash disk insertion in the mobile phone at this moment, mobile phone realizes that just by the path of usb host end equipment the turnover data flow of usb host end is docked with the turnover data flow of USB flash disk.
When realizing that the present invention utilizes the method for file in the cell phone managing USB flash disk, at first mobile phone interface is arranged to use the pattern of USB flash disk, the analog switch module just switches to the path of usb host end equipment, end with the switching cable connects mobile phone again, the other end connects USB flash disk, dock with the turnover data flow of USB flash disk with the turnover data flow that realizes mobile phone usb host end, described switching cable one end is provided with the USBHeader connector, the other end is provided with USB Socket connector, described USB Header connector is connected with mobile phone, described USB Socket connector is connected with USB flash disk, and power module provides voltage, finishes the physical connection of usb communication.At last, just can utilize the management tool of mobile phone that the file in the USB flash disk is managed, comprise the file in the USB flash disk that duplicates, deletes, renames, and the file directory management of disposing corresponding MP3 player, directly to read the file in the USB flash disk.Because general USB flash disk all is with Windows FAT32 file format, so mobile phone of the present invention must be supported the file management of FAT32.
