Abstract
The utility model discloses a movable storage device switching device that consists of a switching box(1) and the storage device driver(2) inside the switching box(1) which is provided with a connector data switching board(8) which has mutually connected USB encoding/decoding circuit(9) and a USB control circuit(10), the USB encoding/decoding(9) circuit is connected with the storage device driver(2) through a data wire(7) and a power cord, the switching box(1) is provided with a USB connector(4) and a DC electricity connector(3), both of which are connected with the connector data switching board(8) through conductors. The utility model support electric swap and fully utilize the property of high speed and large amount of information transmission of the hard disk and the optical-driver.
Description
Technical field
The utility model relates to a kind of memory device switching device, is used for two data interchanges between separate computer.
Background technology
People because of need of work often the data on the computer, move on on another computer and handle, but depending merely on CD or floppy disk installs on another computer, often can not satisfy the needs of large information capacity, this just needs the whole storage device driver of a computer directly to be connected with another computer, and energy plug and play, but existing computer with the hard disk drive of ide interface do not support with inserting with usefulness, can not warm swap, after opening cabinet and twisting screw, just can choose and neither domestic consumer can accomplish.
Summary of the invention
The purpose of this utility model provides a kind of energy warm swap, and can be with the movable memory equipment switching device of inserting with usefulness.
The technical scheme that realizes above-mentioned purpose is: a kind of movable memory equipment switching device, comprise the storage device driver in interconnecting device and the interconnecting device, has the interface data change-over panel in the interconnecting device, have interconnective USB coding/decoding circuit and USB control circuit on the interface data change-over panel, this USB coding/decoding circuit is connected with storage device driver with power lead by data line, have USB interface and DC power interface on the interconnecting device, and this USB interface is connected with the interface data change-over panel by lead with the DC power interface.
After adopting technique scheme, be provided with USB interface on the interconnecting device, and the hot swap characteristics of USB makes the driver of memory device can insert other computer at any time easily, make things convenient for duplicating and moving of data, give full play to the characteristic that hard disk, CD-ROM drive transmit information at a high speed, in a large number, DC interface external power supply on the interconnecting device can provide internal circuit work and the required power supply of storage device driver work, and driver can be worked reliably.USB coding/decoding circuit on the data-switching plate and USB control circuit become the storage device driver conversion of signals usb signal of standard, export by USB interface, and pass the signal along on other computer by the USB interface on other computer, and whole switching device volume is little, be more convenient for carrying than notebook computer, on different computers, handle same data message for people and bring great convenience.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is inner annexation figure of the present utility model;
Fig. 4 is the circuit theory diagrams on the interface data change-over panel among Fig. 3.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～4, a kind of movable memory equipment switching device, comprise the storage device driver 2 in interconnecting device 1 and the interconnecting device 1, has interface data change-over panel 8 in the interconnecting device 1, have interconnective USB coding/decoding circuit 9 and USB control circuit 10 on the interface data change-over panel 8, this USB coding/decoding circuit 9 is connected with storage device driver 2 with power lead 6 by data line 7, have USB interface 4 and DC power interface 3 on the interconnecting device 1, and this USB interface 4 is connected with interface data change-over panel 8 by lead with DC power interface 3.USB coding/decoding circuit 9 is made up of integrated circuit NEET2270 and peripheral circuit thereof, and USB control circuit 10 is made up of integrated circuit AM1 (microprocessor) and AM29F010 peripheral circuits such as (storeies).
As shown in Figure 1, 2, USB interface 4 and DC power interface 3 all are arranged on the back side of interconnecting device 1.Adopt this structure to be convenient to interconnecting device 1 and plug main frame.
Shown in Fig. 2,4, interconnecting device 1 back side also has internal drive interface 5, have inner drive signaling conversion circuit 11 on the interface data card extender 8, internal drive interface 5 is connected with storage device driver 2 with this inner drive signaling conversion circuit 11 by lead.This structure is convenient to being connected of interconnecting device 1 and main frame inside.
Principle of work of the present utility model is as follows: when boxcar 1 inserts main frame inside, interface data change-over panel 8 recognizes it in main frame inside, do not worked by the usb signal change-over circuit that USB coding/decoding circuit 9 and USB control circuit 10 are formed, storage device driver 2 data-signals are sent to main frame by inner drive signaling conversion circuit 11 conversion backs by internal drive interface 5.When interconnecting device 1 takes out, can link to each other with the computing machine that has USB interface arbitrarily by the USB interface 4 of outside, then with DC power interface 3 external DC power supplys, USB coding/decoding circuit 9 and USB control circuit 10 operate as normal, storage device driver 2 data-signals are converted into the usb signal that any computing machine can both be discerned, the memory device conversion equipment just can be given full play to the characteristic that hard disk, CD-ROM drive transmit information at a high speed, in a large number by USB interface 4 and other host exchanging data.
