Utility model content
Technical problem to be solved in the utility model is: a kind of information equipment shared device is provided, has feature simple to operate, easy to use, effectively realized most optimum distribution of resources, save operation cost, and greatly reduce the fault rate to computer operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of information equipment shared device, comprise shell and be positioned at several usb host interfaces and several USB information equipment interfaces on shell, also comprise the control change-over switch matching with usb host interface, and be positioned at USB 2.0 HUB master control IC and the power modules of shell, wherein usb host interface connects control change-over switch, control change-over switch and connect USB 2.0 HUB master control IC, USB 2.0 HUB master control IC connect USB information equipment interface, and power module connects USB 2.0 HUB master control IC.
Described control change-over switch is that key switch, its button are positioned on shell.
Described key switch is the interactive key switch of four linkage interlocked self-lockings.
Described usb host interface is female mouthful of four A type USB, and the stitch that each A type USB is female mouthful accesses the stitch of corresponding button in the interactive key switch of four linkage interlocked self-lockings.
Described USB 2.0 HUB master control IC are the FE1.1S type USB 2.0 HUB chips of Taiwan Tang Ming company, the interactive key switch bus of four linkage interlocked self-lockings is accessed in one end of FE1.1S type USB 2.0 HUB chips, and the other end expands four stitch access USB information equipment interfaces.
Described USB information equipment interface is female mouthful of four A type USB.
The beneficial effect that adopts technique scheme to produce is:
1, simple to operate, easy to use, make easily, with low cost, and be convenient to quick failure judgement.
2, effectively realized most optimum distribution of resources: be the USB information equipment that a computing machine is equipped with printer and so under normal circumstances, but can be used alternatingly same printer by multicomputer after using this device, resource utilization is more reasonable.
3, greatly reduce the fault rate to computer operation: for example clerical workforce uses information Intranet machine and information outer net machine simultaneously, or dispatching and monitoring person need to be in the face of many cover mouses and keyboards while using information Intranet machine and dispatching and monitoring machine simultaneously, can make mistakes unavoidably when blocked operation back and forth.And only needing a set of mouse-keyboard can be connected on many computing machines after using this device, the history of " looking for keyboard or mouse " has not existed, and greatly improves operation accuracy.
