Technical field
The present invention relates to a kind of Wireless Keyboard, particularly a kind of Wireless Keyboard of multi-functional USB.
Background technology
Along with the prosperity of computer industry, the related quick change that causes each item periphery.Especially input equipment (keyboard, mouse or Contact plate etc.) also begins to become wireless transmission from existing wired connection.Because the relation of wireless transmission, the user can move and adjust the most comfortable typewriting environment easily.
Each item of online is handled though the user can conveniently typewrite; But for fear of the signalling formula of Wireless Keyboard, the user can't directly operate through the return function that Wireless Keyboard personal computer carries out machine open/close, Basic Input or Output System (BIOS).The user need install wired keyboard separately just can use above-mentioned functions.Just lost the convenience of Wireless Keyboard thus.
Summary of the invention
In view of above problem, fundamental purpose of the present invention is to provide a kind of Wireless Keyboard of multi-functional USB, is used to trigger the control function of personal computer.
For achieving the above object, the Wireless Keyboard of the multi-functional USB that the present invention disclosed comprises keyboard body, receiver module and embedded controller.The keyboard body has a plurality of buttons, signal transmitting module and coding circuit, and coding circuit produces corresponding character signal when being pressed according to button, and signal transmitting module converts character signal wireless signal into and sends wireless signal; Receiver module is with the transmission of wireless signals that is received to personal computer; And embedded controller is arranged among the personal computer; Also comprise clock pulse control pin in the universal serial bus module of receiver module, universal serial bus module is electrically connected at the embedded controller of personal computer; Embedded controller sends the corresponding function trigger pip according to the compressing time length of received wireless signal to the South Bridge chip group.
The present invention provides a kind of Wireless Keyboard of supporting USB, and the user can pass through existing button, and through different compressing times, so as to carrying out function corresponding.Thus, the user can not need open the casing of personal computer, can accomplish data recovery or removing to motherboard.
Describe the present invention below in conjunction with accompanying drawing and specific embodiment, but not as to qualification of the present invention.

Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and principle of work are done concrete description:
Please refer to shown in 1 figure, it is a configuration diagram of the present invention.The Wireless Keyboard of USB of the present invention comprises keyboard body 110, on personal computer, then is provided with the receiver module 120 of corresponding keyboard body 110, and also is provided with an embedded controller 130 in this personal computer.The kind of USB is mini joint A (mini-A) or mini joint B (mini-B).
Keyboard body 110 has a plurality of button 111, signal transmitting module 112 and coding circuit 113.Coding circuit 113 produces corresponding character signal when being pressed according to button 111.Signal transmitting module 112 converts character signal into wireless signal and sends wireless signal and give personal computer.Wherein, button 111 is when different compressing times, and coding circuit 113 can produce the function corresponding signal according to the time length of pushing.
Embedded controller 130 is set among the personal computer; Embedded control 130 devices are electrically connected at receiver module 120 through clock pulse control pin 122, and embedded controller 130 sends the corresponding function trigger pip according to the compressing time length of received wireless signal to South Bridge chip group 100.
Please cooperate shown in Figure 3ly, it is an operation workflow synoptic diagram of the present invention.The present invention includes following steps:
Step S310: the user pushes the button on the Wireless Keyboard, and Wireless Keyboard converts character signal into wireless signal through signal transmitting module and sends wireless signal and give personal computer;
Step S320: receiver module is sent to the embedded controller in the personal computer with received wireless signal through clock pulse control pin;
Step S330: received wireless signal is decoded by embedded controller; And
Step S340: embedded controller carries out the control corresponding function according to the South Bridge chip group that decoded result drives in the personal computer.
For clearly demonstrating different compressing time of the present invention, thus be each item function of following table 1 as explanation, but the present invention only is confined to this.
| Control function/corresponding hot key | Compressing time |
| Increase volume (Fn+ " 3 ") | 50ms |
| Reduce volume (Fn+ " 4 ") | 30ms |
| Burning BIOS in POST (power key+" F ") | 100ms |
| Open BIOS (power key+" F2 ") | 200ms |
| Open CD-ROM drive (Fn+ " C ") | 300ms |
| Hard disk is carried out redundant (power key+" X ") | 400ms |
| Carry out start (power key) | 500ms |
| Open Boot menu (power key+" F12 ") | 600ms |
Table 1. control function and compressing time correspondence table
When personal computer when shutdown (meaning is promptly crossed the machine of establishing by cable), the part assembly in the personal computer still has electric current to be passed through, and so as to keeping those assemblies running is provided.For example, set (as: system time, device setting or peripheral kind etc.) in the middle each item that can write down personal computer of complementary metal-oxide layer-semiconductor (Complementary metal-oxide-semiconductor is called for short CMOS).Therefore, receiver module 120 can keep its operating state through this electric current.Therefore after the present invention can be applied to personal computer and not start shooting preceding or started shooting.After the receiver module 120 of personal computer receives, wireless signal is sent to embedded controller 130.Convert wireless signal to corresponding operational order by embedded controller 130 to personal computer.Then, embedded controller 130 drives corresponding apparatus through South Bridge chip group 100.
Below be to describe when not starting shooting with personal computer.When the user pushed function key (corresponding to " Fn " key) and other button on the keyboard body 110, coding circuit 113 produced the function corresponding signal according to the time span that button 111 is pressed.For example: when pushing Fn and numerical key " 3 " and reaching 30 microseconds, then signal transmitting module 112 can be sent a wireless signal that increases volume to personal computer.Perhaps, when pushing Fn and letter key " C " and reaching 300 microseconds, then signal transmitting module 112 can be sent a corresponding wireless signal and give personal computer, and sends the wireless signal of a unlatching CD-ROM drive, and drive optical drive is opened and moved back the sheet mouth.
The present invention provides a kind of Wireless Keyboard of supporting USB, and the user can pass through existing button 111, and through different compressing times, so as to carrying out function corresponding.Thus, the user can not need open the casing of personal computer, can accomplish data recovery or removing to motherboard.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
