Description

Multi-keyboard computer input system

Technical field

[0001] The present invention relates to a computer input system, and more particularly to a multi-keyboard computer input system for teaching. Background technique

[0002] At present, with the continuous development of society and science and technology, the development and application of computer science and technology has also been highly valued by countries all over the world. With the development and application of the network, big data and cloud platforms have become more and more national competitiveness. The performance, and all these processing and application are inseparable from the data entry. At present, the machines produced by major computer manufacturers are defaulted to a standard keyboard, a mouse, and multiple USB storage devices, supporting the use of one person and one machine. Mode, the computer does not classify all keyboard input information, and treats it as a default standard keyboard. This mode restricts the application of the computer under certain circumstances. In particular, the use environment requires a common program to implement data processing. In the case of multiple manual keyboard input, the prior art method has almost no other feasible methods except for using a high cost, a large space occupation, and a server multiple terminal networking mode. For example: In a one-to-many classroom teaching or examination, teachers often use computerized projectors and multimedia teaching methods for speakers. They can only output knowledge to students, and cannot input the students’ mastery. The effect of teaching. Another example: In the teaching process of the computer room, one computer per person, watching the computer screen in the long room, seriously hurts the students' vision; the students have computer control, and there are things that are not allowed in the classroom, and the teacher is hard to find. The computer labs in Tongyi are expensive and occupy a large space. It is not convenient for students to write, draw, and attend classes in the computer room. For example: In the course of various competitions, the answering problem is currently realized by a special responder to achieve this function. The responder is actually controlled by the CPU chip, and its inter-turn accuracy and processing efficiency are far less than the computer. Most of the applications of the responder still need to be connected to the computer, which increases the cost. What's more important is that both the teaching process and the rushing process require multiple keyboards to input information in the same order, regardless of the order.

technical problem

[0003] In order to solve the problem that multiple keyboards can input information in the same order, without prioritization In the related patent reports, there are also ways to connect multiple keyboards to connect multiple keyboards. However, such a system not only increases the cost of purchasing multiple channels, but also allows only one keyboard and the same time. The computer is connected, and multiple keyboards cannot be input to the computer. There is also a dedicated add-on microcontroller connected via a computer, which is then connected to multiple keyboards by the microcontroller, but this adds to the cost and adds a description of the technical problem description here.

The input information is classified by keyboard according to the requirements of the computer.

[0008] The data integrity guarantee mechanism is as follows: It is known by computer principle that a computer keyboard event is generated, and data is transmitted in units of characters. In a character transmission process, the host does not respond to any event. This in principle ensures that the integrity of the data input from multiple keyboards is not destroyed. It is known from the computer principle that the computer interrupt uses the interrupt list, so the keyboard events that occur at the same time can be saved. In the stored interrupt table, in the case where the host system processing speed is much higher than the manual input, there is no loss of input data. In the communication process of the same computer, the communication between the keyboard CPU and the host computer uses data verification and error retransmission mechanism, which ensures that the transmission data is not damaged by chance.

. At present, the operating system can support up to 127 port addresses, so the number of keyboards that can be connected to one host in this system is less than 127. [Note: Connections not indicated in this solution, such as the connection between the display device and the computer, the connection between the USB HUB and the computer, the normal connection according to the product manual or technical operation specification, the keyboard can be a wired keyboard, or wireless keyboard】

Advantageous effects of the invention
