Abstract
The utility model provides an electronic device with dual USB (Universal Serial Bus) interface, wherein the electronic device mainly comprises a first USB interface module, a second USB interface module, a storage module, a control storage module electrically connected with the storage module, and a switch module respectively electrically connected with the control storage module, the first USB interface module and the second USB interface module, when the switch module is switched on, the control storage module is used for carrying out data storage on the storage module through the first USB interface in the electronic device, and when the switch module is switched off, the control storage module is used for carrying out data storage on the storage module through the second USB interface module in the electronic device. The electronic device with the dual USB interfaces is capable of storing materials, can be connected to a computer through the other USB interface for correcting data during material storage, thereby saving time, reducing insert and draw frequency and effectively preventing from damaging the USB interfaces.
Description
Technical field
The utility model relates to a kind of electronic installation, relates in particular to a kind of electronic installation with double-USB interface.
Background technology
At present, USB flash disk on the market generally only has a USB interface, and plug and play during use, purposes are extremely wide, but generally speaking only are used as memory storage.
In storing process, owing to need constantly plug USB flash disk, be easy to injure the surface of contact of the USB interface on the USB flash disk, and result in the USB flash disk loose contact, can not use.
When USB flash disk uses when low end (for example oscillograph) is upper, if the data that the user wants real time modifying to deposit into, then need USB flash disk is taken off from low end, after inserting computer, carry out again the modification to data, in this process that repeatedly plugs and revise, not only waste user's time, and injure easily the surface of contact of USB interface.
Summary of the invention
In view of the above problems, the utility model provides a kind of electronic installation with double-USB interface, not only can store simultaneously data, but also can utilize another interface to be connected to computer data is made amendment.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of electronic installation with double-USB interface, and wherein, this electronic installation mainly comprises the first usb interface module; The secondary USB interface module; Memory module; Control store module with this memory module electric connection; And switch module, be electrically connected with this control store module, the first usb interface module and secondary USB interface module respectively, when this switch module is opened, this control store module is stored data by this first usb interface module to memory module in this electronic installation, when this switch module was closed, this control store module was stored data by this secondary USB interface module to memory module in this electronic installation.
Better, the utility model provides a kind of electronic installation with double-USB interface, and wherein, this electronic installation also comprises the first display module that is electrically connected with this first usb interface module.
Better, the utility model provides a kind of electronic installation with double-USB interface, and wherein, this electronic installation also comprises the second display module that is electrically connected with this secondary USB interface module, and described the first display module and the second display module are the LED lamp.
Better, the utility model provides a kind of electronic installation with double-USB interface, and wherein, described control store module is EEPROM (Electrically Erasable Programmable Read Only Memo).
Compared to prior art, the utility model provides a kind of electronic installation with double-USB interface, not only can be when storing data, can utilize another USB interface to be connected to computer, the while Update Table, thus save time, and reduce the plug number of times, effectively avoided the damage USB interface.
Description of drawings
Fig. 1 is block diagram of the present utility model
Embodiment
Please refer to shown in Figure 1ly, be block diagram of the present utility model.The utility model provides a kind of electronic installation 10 with double-USB interface, not only can when storing data, can utilize another USB interface to be connected to computer, the while Update Table, thereby save time, and reduce the plug number of times, effectively avoided the damage USB interface.
Wherein, described electronic installation 10 with double-USB interface mainly comprises the first usb interface module 101, secondary USB interface module 102, control store module 103, memory module 104, switch module 105, the first display module 106 and the second display module 107.
Again, described control store module 103 is electrically connected with this memory module 104, controls with the data storage to this memory module 104.
Described switch module 105 is electrically connected with this control store module 103, the first usb interface module 101 and secondary USB interface module 102 respectively, the first display module 106 is electrically connected with this first usb interface module 101, and the second display module 107 is electrically connected with this secondary USB interface module 102.
So, when this switch module 105 is opened, this control store module 103 is stored data in this electronic installation by 101 pairs of memory modules 104 of this first usb interface module, when this switch module 105 was closed, this control store module 103 was stored data in this electronic installation by 102 pairs of memory modules 104 of this secondary USB interface module.
In present embodiment, described the first display module 106 and the second display module 107 are the LED lamp.Wherein, the first usb interface module 101 and secondary USB interface module 102 connect together via control loop, and then are connected in the USB interface of computer, with the storage data.This control store module 103 can be utilized EEPROM (EEPROM (Electrically Erasable Programmable Read Only Memo), get final product the ROM (read-only memory) of user's change) set, when the first usb interface module 101 in read-write, utilize switch module 105 to disconnect the control loop of secondary USB interface module 102, thereby avoid the user to do the action of access data at the first usb interface module 101 and secondary USB interface module 102 simultaneously, and cause the access data failure.In addition, because this first usb interface module 101 and secondary USB interface module 102 connect respectively the LED lamp, the user can learn current USB flash disk whether in reading according to the light and shade of LED, and the action of avoiding this first usb interface module 101 and secondary USB interface module 102 to read simultaneously.
