technical field

The present invention relates to a computer and its communication method, especially a computer with multiple wired and wireless terminals and its communication method.

Background technique

With the development of science and technology, personal computer (Personal Computer, PC) has increasingly become an important tool in people's work, study, life, communication, entertainment and other aspects. Existing PCs are mainly designed for personal use. Each host is connected to a set of user terminal equipment (including monitors, keyboards, mice, CD-ROM readers, U disks, speakers, cameras, etc.) through corresponding signal lines. Usually only one user can be served when in use. For PCs whose computing power is not too strong in the early stage, this usage method is suitable, because its computing power can only meet the requirements of one user. However, with the improvement of PC computing power in recent years, especially the emergence of hyper-threading and multi-core technology, ordinary users only use a small part of the computing power of the computer most of the time. For example, many users use computers for text operations on a daily basis. Or browse the web, the computer is idle or running at low speed most of the time. Therefore, in some occasions that do not require strong computer computing capabilities, such as inquiries in libraries and reading rooms, audio-visual teaching, student computers in multimedia classrooms, etc., providing each user with an independent computer will significantly increase the construction cost. Cause a waste of software and hardware resources.

On the other hand, due to technical limitations, the transmission rate of the previous wireless transmission technology can only realize data transmission of low-speed devices such as mouse and keyboard, but cannot meet the requirements of real-time transmission of large amounts of data such as video, making most monitors, U disks, etc. The terminal device can only be connected to the host computer through the signal line, which limits the location where the user can use the computer, and it is troublesome to rearrange and move the computer. Therefore, in many occasions, the user prefers a terminal that can move freely. With the advancement of technology, a variety of new wireless transmission technologies have emerged in recent years, making it possible to transmit data at a high speed within a short distance. For example, the current ultra-wide-band (UWB) wireless transmission technology can It provides a data transmission rate of up to 480Mbps between 10.6GHz and 10.6GHz frequencies, which provides a good technical basis for solving the above problems.

(2) in the host transceiver, order that the line termination unit interface will be imported and data are sent to the main frame channel controller, for the terminal equipment that special purpose interface is arranged in the host interface circuit, the main frame channel controller directly is sent to main frame by special purpose interface with its data, for using the terminal equipment that shared interface transmits in the host interface circuit, the main frame channel controller is according to the terminals different in the terminal device interface circuit and the input interface of equipment, in order and data, add terminal and equipment mark, send to main frame with the form of the packet shared interface by correspondence in the host interface circuit;

(3) data that send for interface from certain terminal equipment special use, main frame is handled accordingly according to the terminal equipment of interface correspondence; For the packet that sends from a plurality of terminals or the shared interface of equipment, main frame carries out decapsulation to it, and handles accordingly according to terminal and device identification in the bag.

6. computer according to claim 4 carries out the method for main frame and terminal communication, it is characterized in that order and data that described main frame mails to each wireless terminal transmit according to the following steps:

(1) main frame order or the data that will give particular device in certain terminal send to host transceiver by the interface that is connected with host transceiver, wherein, interface for certain terminal equipment special use, main frame directly will be ordered and data send by this interface, for a plurality of terminals or the shared interface of equipment, main frame adds terminal and device identification on order that will transmit and data, send by this interface with the form of packet;

(2) host transceiver receives the data that main frame sends and delivers to the main frame channel controller by its host interface circuit, interface for certain terminal equipment special use in the host interface circuit, the main frame channel controller adds terminal and equipment mark on its order that sends and data, send to the terminal transceiver that is connected with target terminal by wireless transport module with the form of packet; For the shared interface of a plurality of terminals or equipment in the host interface circuit, the main frame channel controller sends to the terminal transceiver that is connected with target terminal with its packet that sends by wireless transport module;

(3) after the wireless transport module of terminal transceiver receives the packet that host transceiver sends with wireless mode, packet is delivered to the terminal channel controller, the terminal channel controller is the packet decapsulation, and delivers in the terminal device interface circuit corresponding apparatus interface according to device identification in the bag and export;

(4) after terminal equipment receives the data that the terminal transceiver sends by holding wire, handle accordingly.

7. computer according to claim 4 carries out the method for main frame and terminal communication, it is characterized in that order and data that described each wireless terminal mails to main frame transmit according to the following steps:

(1) terminal equipment receives the order and the data of user's input, and the terminal device interface that provides by the terminal transceiver is input to the terminal transceiver;

(2) in the terminal transceiver, order that terminal device interface will be imported and data send the terminal channel controller to, the terminal channel controller is according to adding terminal and equipment mark in the do not coexist order and the data of interface of input, send by its wireless transport module with the form of packet;

(3) after the wireless transport module in the host transceiver receives packet, send it to the main frame channel controller, for the terminal equipment that special purpose interface is arranged in the host interface circuit, the main frame channel controller is the packet decapsulation, and data directly are sent to main frame by the special purpose interface of correspondence; For using the terminal equipment that shared interface transmits in the host interface circuit, the main frame channel controller sends to main frame with packet by shared interface corresponding in the host interface circuit;
