Abstract
Of the present utility modelly belong to electronic circuit technology field, specifically provide a kind of can to multiple devices operation intelligent keyboard, it mainly comprises USB passage a(1), USB passage b(2), Channel-shifted button (3), Channel-shifted execution module (4), keyboard (5).By operating walk way switching button, to freely to USB passage a(1) and USB passage b(2) switch, thus can make with a keyboard two operates.This device is applicable to operate two main frames with a keyboard, has to simplify existing needs and use multiple keyboard to carry out the complexity of multiple devices operation, reduces the number advantage simple to operate of desk circuit.
Description
Technical field
Of the present utility modelly belong to electronic circuit technology field, specifically provide and can, to the intelligent keyboard of multiple devices operation, be applicable to operate two main frames with a keyboard.
Background technology
Computing machine (computer) is commonly called as computer, is a kind of robot calculator device for supercomputing, can carries out numerical evaluation, can carry out logical calculated again, also have store-memory function.Can run according to program, automatically, the modernization intelligent electronic device of high speed processing mass data.Along with the development of science and technology, computing machine be dissolved into we study, work, go in life, people will spend a large amount of time in face every day on computers.In computed process, often run into such sight, need to operate multiple devices simultaneously, the technology of existing keyboard can only to same operate, if desired multiple devices are operated and just need multiple keyboard, the number of wires of desktop will be increased like this, increase the mixed and disorderly degree of desktop.
For this situation, the utility model provides the intelligent keyboard to multiple devices operation, by operating walk way switching button, to freely switching USB passage a and USB passage b, thus can make with a keyboard two operates.
Summary of the invention
Object of the present utility model is that the technology of existing keyboard to same operate, if desired can only be carried out operation to multiple devices and will increase multiple keyboard, thus increases operation complexity and the various problem of circuit.
For this reason, the utility model provides a kind of can, to the intelligent keyboard of multiple devices operation, it is characterized in that comprising: USB passage a, USB passage b, Channel-shifted button, Channel-shifted execution module, keyboard.
Described Channel-shifted execution module, it comprises microprocessor, channel switch, power supply.
Described Channel-shifted execution module, its input end is the output terminal of keyboard signal, and the output terminal of its inner passage switch is connected with the input end of USB passage b with USB passage a respectively.
Described keyboard, Channel-shifted button is equipped with on its surface.
Described microprocessor, its input end is connected with Channel-shifted button, and its output terminal is connected with channel switch.
Described power supply is the chip power supply of whole device.
The beneficial effects of the utility model: use single keyboard can complete operation to multiple devices, simplifying existing needs uses multiple keyboard to carry out the complexity operated, and reduces the number of desk circuit.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation

Embodiment
Embodiment 1
To the connection diagram of the intelligent keyboard of multiple devices operation, can comprise: USB passage a1, USB passage b2, Channel-shifted button 3, Channel-shifted execution module 4, keyboard 5 if Fig. 1 is that the utility model is a kind of.
The inside connection layout of the Channel-shifted execution module 4 in Fig. 1 as shown in Figure 2, comprises and comprises microprocessor 6, channel switch 7, power supply 8.
Composition graphs 1, Fig. 2, its annexation is:
Described Channel-shifted execution module 4, its input end is the output terminal of keyboard signal, and the output terminal of its inner passage switch is connected with the input end of USB passage b2 with USB passage a1 respectively.
Described keyboard 5, Channel-shifted button 3 is equipped with on its surface.
Described microprocessor 6, its input end is connected with Channel-shifted button 3, and its output terminal is connected with channel switch 7.
Described power supply 8 is the chip power supply of whole device.
Its principle of work is: be connected respectively to by USB passage a1 and USB passage b2 on two different equipment respectively, work if current duty is USB passage a1, microprocessor 6 can with the mode monitoring channel switching button 3 of down trigger, when Channel-shifted button 3 is pressed time, microprocessor 6 will change the duty of channel switch 7, make it be transformed into USB passage b2 from USB passage a1 work to work, thus to an other operate.
Embodiment 2
On the basis of embodiment 1, keyboard 5, there is a square Channel-shifted button 3 at the middle part on its surface.
Embodiment 3
On the basis of embodiment 1, microprocessor 6, its can be various types of single-chip microcomputer as, MSP430 series, 51 series etc.
Embodiment 4
On the basis of embodiment 1, power supply 8, it is button cell, can complete the chip power supply to whole keyboard, when running down of battery, can change.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection domain of the present utility model with the same or analogous design of the utility model.
