Or panel shines, and button letter can be also clearly seen that in the case where not turning on light at night.Keyboard is connect using USB mostly
Head, and connected by the USB interface of USB joint and host, and current host often provides 3.0 liang of USB 2.0 and USB
Kind interface.According to relevant consensus standard, the supply voltage of USB 3.0 is direct current 5.0V ± 5%, the power supply with standard USB 2.0
Voltage is identical.The difference is that standard regulation 3.0 maximum output currents of USB are not less than 0.9A, and the maximum output of USB 2.0
Electric current maximum 0.5A, in contrast USB 3.0 can export the power of bigger.If backlight keyboard is set as maximum defeated in manufacture
Enter the current standard that electric current is not less than 0.9A USB 3.0, host can be burnt out when then being connected with 2.0 host interface of USB；If the back of the body
Light keyboard is set as the current standard of maximum input current 0.5A USB 2.0 in manufacture, then with 3.0 host interface of USB
When being connected, and the advantage of keyboard cannot be played.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of energy effective protection host
The keyboard system with automatic identification electrical parameter of USB interface sharpest edges can be played again.
The technical solution adopted in the present invention is：The present invention includes that processor, key-press module, LED light module and USB connect
Mouthful, the keyboard system with automatic identification electrical parameter further includes handover module, the key-press module, LED light module, institute
It states handover module to be electrically connected with the processor, the power cord of the USB interface is electrically connected with the handover module, institute
It states LED light module to be electrically connected with the handover module, the power line data line and the processor of the USB interface are electrical
Connection；When work, the electrical parameter that the processor accesses the USB interface is identified, and then the processor controls institute
State handover module and by LED light module described in corresponding plant-grid connection.
Further, the handover module includes switching switch, the first power supply circuit and the second power supply circuit, and described first supplies
Circuit and second power supply circuit are in parallel and switch and be electrically connected with the switching, the power cord of the USB interface and
The switching switch electrical connection, the switching switch are connect with the processor signal.
Further, the keyboard system with automatic identification electrical parameter further includes the finger being electrically connected with the processor
Show lamp.
Further, the maximum current that first power supply circuit provides is 0.5A.
Further, the electric current that second power supply circuit provides is not less than 0.9A.
The beneficial effects of the invention are as follows：Since the present invention uses the design of automatic identification electrical parameter, including processor, button
Module, LED light module and USB interface, the keyboard system with automatic identification electrical parameter further includes handover module, described
Key-press module, LED light module, the handover module with the processor be electrically connected, the power cord of the USB interface with
The handover module is electrically connected, and the LED light module is electrically connected with the handover module, the power supply of the USB interface
Line data line is electrically connected with the processor；When work, the electrical parameter that the processor accesses the USB interface is known
Not, then the processor controls the handover module by LED light module described in corresponding plant-grid connection, so, the present invention
The fine protected host of energy, and USB interface sharpest edges can be played.
Description of the drawings
Fig. 1 is the principle of the present invention structure chart.
Specific implementation mode
As shown in Figure 1, in the present embodiment, the present invention includes processor 1, key-press module 2, LED light module 3 and USB
