Description

A kind of muliple keyboards computer input

Technical field

The present invention relates to a kind of computer input, especially a kind of muliple keyboards computer input.

Background technology

At present, along with society and the development of science and technology, also the great attention of countries in the world is subject to the development and apply day of computer science and technology, along with the development and apply of network, large data, cloud platform more and more becomes the performance of national competitiveness, and all these process and application all be unable to do without the typing of data, the machine of current each large computing machine manufacturers produce is all acquiescence QWERTY keyboard, one mouse, multiple USB storage device, what support is the using forestland of people one machine, computing machine not to be classified process to all keyboard input informations, a QWERTY keyboard all as acquiescence processes, this pattern limits computer application in any case, particularly environment for use requires to realize data processing by a common program, when needing multiple manual keyboard to input, prior art mode is except with high cost, take up room more, the multiple terminal networking pattern of one station server, almost there is no other feasible method.Such as: teacher is in the classroom instruction or examination of one-to-many, the multimedia teaching method adopting the projector of computer to add audio amplifier at present more, knowledge output can only be carried out to student, can not input students situation, thus the effect of teaching can not be understood in time.For another example: at microcomputer room teaching process, everyone computer, watches computer screen, grievous injury student eyesight for a long time; Student has conputer controlled to weigh simultaneously, does the unallowed thing in classroom sometimes, and teacher is also difficult to find; Simultaneously micro-computer classroom cost is high, duty large, student writes in microcomputer room, draw, listen to the teacher also not too convenient.For another example: during the games various, race to be the first to answer a question problem, mostly be to realize making this function by special question-and-answer game apparatus at present, question-and-answer game apparatus reality is also controlled by CPU stamen sheet, its time precision and process timeliness are more than not computer, and question-and-answer game apparatus major applications still will be connected on computer, inappropriately add cost.

In Patents report, also the mode having employing to connect multi-way switch carries out muliple keyboards input, but such system not only increases the cost purchasing multi-way switch, importantly the same time still only allows a keyboard to be connected with computer, can not realize multiple keyboard and input computer simultaneously.Also have by being connected special additional microcontroller with computer, be then connected with muliple keyboards again by microcontroller, but inappropriately like this add cost.

Universal due to computer, the development of internet, in computer, a little change, is all can produce far-reaching influence to society.

Summary of the invention

For solving an above existing difficult problem, the invention discloses a kind of muliple keyboards computer input.

A kind of muliple keyboards computer input, comprise multiple keyboard, computer, display device (as projector, large screen television etc.), described muliple keyboards computer input is undertaken being connected by computer and muliple keyboards and the computer in muliple keyboards computer input and display device is carried out connecting and composing this system.

A nearly step, described muliple keyboards is directly connected with computer respectively.

A nearly step, described muliple keyboards computer input also comprises USBHUB, and described muliple keyboards connects USBHUB, and described USBHUB connects computer and requires that carrying out classification to input information keypad device number processes by computer foundation.

Beneficial effect; In teaching application, teacher not only can make full use of directly perceived, the vivid advantage of existing multimedia teaching, when investing little, as long as every student joins a keyboard, just can realize the interaction of teaching process, real-time detection students situation record, if the computer networking in classroom, the large data that these teaching produce, not only can point out teacher's students knowledge, level and the quality of the teaching of every, each department teacher can also be weighed, thus provide possibility for the large data platform analysis of nationwide teaching.As a rule; micro-computer classroom also can become a computer; multiple input keyboard; by teacher's main control system; no matter student typewrites, programme, working procedure can stare at computer screen; as long as and by program, for wanting to see that the classmate of screen divides a giant-screen region and just can realize, thus protect student eyesight.In the application scenarios that match is raced to be the first to answer a question, computer in most cases directly can be used to connect multiple keyboard, not only reduce the investment buying question-and-answer game apparatus, computer is more convenient to the process of racing to be the first to answer a question result, more practical simultaneously.In election voting and industrial aspect, also there is very large application prospect.
