Abstract
The invention provides an electronic device provided with two USB interfaces. The electronic device mainly comprises a first USB interface module, a second USB interface module, a memory module, a control storage module electrically connected with the memory module, and a switch module which is electrically connected with the control storage module, the first USB interface module, and the second USB interface module respectively. When the switch module is turned on, data storage of the memory module is performed by the control storage module of the electronic device via the first USB interface module; and when the switch module is turned off, data storage of the memory module is performed by the control storage module of the electronic device via the second USB interface module The electronic device provided with two USB interfaces can be connected with a computer via the other USB interface when data storage is performed, and data can be modified at the same time, so that time is saved, plugging and unplugging times are reduced, and damages on the USB interfaces are avoided effectively.
Description
Technical field
The present invention relates to a kind of electronic installation, relate 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, plug and play during use, and purposes is extremely wide, but is generally speaking only used as memory storage.
In storing process, because needs constantly plug USB flash disk, be easy to injure the surface of contact of the USB interface on USB flash disk, and result in USB flash disk loose contact, can not use.
For example, when USB flash disk is used when low end (oscillograph) is upper, if the data that user wants real time modifying to deposit into, need USB flash disk to take off from low end, insert after computer, carry out again the modification to data, in the process that repeatedly plugs and revise at this, not only waste user's time, and easily injure the surface of contact of USB interface.
Summary of the invention
In view of the above problems, the invention provides a kind of electronic installation with double-USB interface, not only can store data simultaneously, but also can utilize another interface to be connected to computer, data are modified.
In order to achieve the above object, the present invention 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; 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 is closed, this control store module is stored data by this secondary USB interface module to memory module in this electronic installation.
Preferably, the invention provides a kind of electronic installation with double-USB interface, wherein, this electronic installation also comprises the first display module being electrically connected with this first usb interface module.
Preferably, the invention provides a kind of electronic installation with double-USB interface, wherein, this electronic installation also comprises the second display module being electrically connected with this secondary USB interface module, and described the first display module and the second display module are LED lamp.
Preferably, the invention provides a kind of electronic installation with double-USB interface, wherein, described control store module is EEPROM (Electrically Erasable Programmable Read Only Memo).
Compared to prior art, the invention 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, while Update Table, thus save time, and reduce plug number of times, effectively avoided damage USB interface.
Accompanying drawing explanation
Fig. 1 is block diagram of the present invention
Embodiment
Please refer to shown in Fig. 1, is block diagram of the present invention.The invention 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, while Update Table, thereby save time, and reduce plug number of times, effectively avoided damage USB interface.
The electronic installation 10 wherein, 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, with the data storage to this memory module 104, controls.
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 is closed, this control store module 103 is stored data in this electronic installation by 102 pairs of memory modules 104 of this secondary USB interface module.
In the present embodiment, described the first display module 106 and the second display module 107 are 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, to store 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 is in read-write, utilize switch module 105 to disconnect the control loop of secondary USB interface module 102, thereby avoid user at the first usb interface module 101 and secondary USB interface module 102, to do the action of access data, and cause access data failure simultaneously.In addition, because this first usb interface module 101 and secondary USB interface module 102 connect respectively LED lamp, user can learn that current USB flash disk is 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 simultaneously to read.
