Abstract
The utility model discloses a kind of USB+PS2 double nip keyboard, described keyboard structure comprises Keyboard Control plate, and the structure of described Keyboard Control plate comprises MCU control chip, keyboard array interface, PS/2 signaling interface and USB interface.The use of a kind of USB+PS2 double nip of the utility model keyboard, can make the keyboard equipment of double nip make user only buy a keyboard equipment and just can use flexibly according to objective circumstances.
Description
Technical field
The utility model relates to computer peripheral equipment technical field, is specifically related to a kind of USB+PS2 double nip keyboard.
Background technology
The current information age, computer application field is ubiquitous, the technical merit of computer peripheral equipment is also improving constantly, such as keyboard equipment, from the initial USB interface keyboard not supporting PS/2 interface keyboard, the finally hot-swappable use of hot plug, arrive the wave point keyboard that current appearance is portable again, the Consumer's Experience of keyboard is become better and better.
USB interface keyboard is the apolegamy peripheral hardware of current computer main flow, and the market share of PS2 interface keyboard progressively declines, some main frame is all default PS/2 interface.But in some special industries, the USB interface of the main frame particularly under concerning security matters environment is limited to use, and therefore, also must use PS2 interface connecting key mouse equipment.
Summary of the invention
The technical problems to be solved in the utility model is: patent of the present invention provides a kind of USB+PS2 double nip keyboard, and the keyboard equipment of double nip makes user only buy a keyboard equipment just can to use flexibly according to objective circumstances.
The technical scheme that the utility model adopts is:
A kind of USB+PS2 double nip keyboard, described keyboard structure comprises Keyboard Control plate, and the structure of described Keyboard Control plate comprises MCU control chip, keyboard array interface, PS/2 signaling interface and USB interface.
The structure of described Keyboard Control plate also comprises keyboard state lamp interface.
Described keyboard structure also comprises keyboard case, keyboard array and pilot lamp, and described Keyboard Control plate, keyboard array and pilot lamp are arranged in keyboard case, USB and PS/2 signal leads to respective standard male interface.Connect main frame with the optional one of USB or PS/2 interface to use.
Note: MCU (MicroControllerUnit) Chinese name micro-control unit, also known as one chip microcomputer (SingleChipMicrocomputer), refer to the appearance along with large scale integrated circuit and development thereof, by the CPU of computing machine, RAM, ROM, timing number device and multiple I/O Interface integration on one chip, form the computing machine of chip-scale, do various combination for different application scenarios and control.In fact, be exactly our said single-chip microcomputer at ordinary times.
The beneficial effects of the utility model are: the use of a kind of USB+PS2 double nip of the utility model keyboard, the keyboard equipment of double nip can be made to make user only buy a keyboard equipment and just can use flexibly according to objective circumstances.
Accompanying drawing explanation
Fig. 1 is the utility model Keyboard Control plate theory diagram;
Fig. 2 is the utility model MCU workflow diagram.
Embodiment
With reference to the accompanying drawings, by embodiment, the utility model is further illustrated:
Embodiment 1:
As shown in Figure 1, a kind of USB+PS2 double nip keyboard, described keyboard structure comprises Keyboard Control plate, and the structure of described Keyboard Control plate comprises MCU control chip, keyboard array interface, PS/2 signaling interface and USB interface.
Embodiment 2:
On the basis of embodiment 1, the structure of Keyboard Control plate described in the present embodiment also comprises keyboard state lamp interface.
Embodiment 3:
On the basis of embodiment 1 or 2, keyboard structure described in the present embodiment also comprises keyboard case, keyboard array and pilot lamp, described Keyboard Control plate, keyboard array and pilot lamp are arranged in keyboard case, USB and PS/2 signal leads to respective standard male interface.
Connect main frame with the optional one of USB or PS/2 interface to use.
MCU control chip scans keyboard array actuation of keys and sends to main frame equipment by PS/2 or USB interface; Keyboard CapLock, ScrollLock and NumberLock state that main process equipment returns is received by MCU by PS/2 or USB interface, and carries out state display by keyboard state lamp interface.
As shown in Figure 2, after device power, when equipment Inspection has main frame to connect to PS/2 interface, complete the initialization procedure of PS/2 interface according to the configuration information of the transmission of main frame, then can use keyboard normal through PS/2 interface; When equipment does not detect that PS/2 Interface Host connects, whether have main frame connect, if any connection, USB interface enumerates initialization, then can use keyboard normal through USB interface if detecting USB interface subsequently.
It should be noted that, PS/2 interface, according to PS/2 agreement, does not support that hot plug uses, and first must connect and restart main frame.
