Technical field
The utility model belongs to technical field of data transmission, relates to a kind of Bus isolation device, relates in particular to a kind of intrinsic safety and non-intrinsic safety usb bus spacer assembly.
Background technology
Along with the development of robotization, informationization technology, the intelligent equipment used under coal mine is more and more, needs the data volume of storage, transmission also increasing.And usb bus is as high speed data transfer bus that can hot plug, the frequency of utilization in the digitizing mine is also more and more higher.
The reason that the restriction USB device is used in down-hole at present is that the most profile of USB device is less, be inconvenient to make the flame proof form, can only be as the intrinsic safety type equipment making, and usb host is (for example: industrial computer) be mostly the flame-proof type structure, can't directly be connected with the intrinsic safety type USB device.
The flame proof industrial computer of current down-hole need to be opened flameproof enclosure when at needs, connecting the peripheral hardwares such as mouse, USB flash disk, then accesses USB device, inefficiency, and the property grasped is not high.
In view of this, nowadays in the urgent need to designing a kind of new usb bus spacer assembly, to overcome the above-mentioned defect of existing transmission mode.
The utility model content
Technical problem to be solved in the utility model is: a kind of intrinsic safety and non-intrinsic safety usb bus spacer assembly are provided, can improve the convenience of transmission data, improve data transmission efficiency.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of mine intrinsic safety and non-intrinsic safety usb bus spacer assembly, described spacer assembly comprises: intrinsic safety USB interface, USB isolating chip, non-intrinsic safety USB interface, intrinsic safety side power supply;
Described intrinsic safety USB interface is connected with the intrinsic safety type USB device, and described intrinsic safety side power supply provides power supply for described intrinsic safety type USB device;
Described intrinsic safety USB interface is connected with the USB isolating chip, and the USB isolating chip is connected with non-intrinsic safety USB interface, and non-intrinsic safety USB interface is connected with non-intrinsic safety usb host.
As a kind of preferred version of the present utility model, described spacer assembly also comprises the mode of operation selector switch, and this mode of operation selector switch is connected with described intrinsic safety USB interface.
As a kind of preferred version of the present utility model, described intrinsic safety side power supply provides intrinsic safety electric source for the intrinsic safety type USB device.
As a kind of preferred version of the present utility model, described intrinsic safety type USB device is intrinsic safety type mouse or intrinsic safety type keyboard or intrinsic safety type USB storage.
