Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
The invention provides a kind of data entry device, the method (is equivalent to remote desktop system for a main frame
As the computer of server in system), this main frame (is equivalent to long-range table by local bus and a client computer
As the computer of client computer in plane system) connect, see Fig. 1, the method comprises the following steps:
S101: determine data to be output；
S102: described data to be output are sent to described client computer by described local bus.
Wherein, the data to be output determined for main frame potentially include multiple situation.Such as, in client computer
When being initially connected to main frame, need to export main interface (desktop) video data of main frame to client computer, with
Just on the display device of client computer, demonstrate the desktop of main frame.Desktop display data is being sent to client computer
Afterwards, user just can see the desktop of main frame on the display device of client-side, the most just can utilize
The input equipment such as mouse, keyboard, performs the mobile operation such as mouse, click at client-side.This in execution
During operation, need to be obtained, by local bus, the operation that user carries out at client-side operating by main frame
(including the particular type etc. of mouse position, action, wherein, the particular type of action includes mouse in instruction
Click, double click operation etc.), then this operational order is processed, produces result, this process is tied
Fruit needs to be sent to client-side.Now, data to be output also include that main frame receives for from client-side
Operational order produce data processed result.
For common remote desktop system, the RDP client modules by being arranged on client-side is needed to log in
To host side RDP service (terminating service module, it is allowed to multidigit user terminal connects and uses main frame,
And show desktop and application program on the remote computer, be remote desktop, express user conversion, remotely
Assist and the base structure of terminal server), then RDP service just can create one for this client computer
Session (session), carries out the mutual of data when this session persistence.And in the embodiment of the present invention
In, in order to reduce complexity and the cost of client-side, client-side does not include RDP client modules, if
According to the scheme of prior art, client computer will be unable to be directly logged onto the RDP service, Jin Erhou of main frame
Continuous operation the most just cannot complete.
To this end, embodiments provide following solution: increase main frame RDP client in host side
Module, when client computer is connected to main frame by the local bus of main frame, first by this main frame RDP client
Module is initiated to log in (i.e. simulation client computer RDP to the terminating service module (RDP service) of host side
Client modules is to the login of the terminating service module (RDP service) of host side), so, terminal takes
Business module (RDP service) will create a session for client computer, determines data to be output (such as
Host table video data), then described data to be output are issued main frame RDP visitor by terminating service module
Family end module, aft engine RDP client modules described data to be output are passed through local bus further
It is sent to client computer, display device that is that such client-side includes or that connect further just can show that
Described data to be output (such as host table).
Wherein, as a example by the view data that data to be output are to be output, described image to be output is eventually
End service module (RDP service) is a series of continuous print desk-top picture image positions of the display generation of a session
Figure, terminating service module (RDP service) is sent to main frame RDP client by session these bitmaps
End module, main frame RDP client modules and then these bitmaps are sent to client computer by local bus.
Wherein, it is the operation that client computer creates session for main frame RDP client modules, can be by external number
According to triggering, such as, user the modes such as certain Menu key specified (software keys or hardware button) are pressed；
In embodiments of the present invention, it is also possible to automatically monitored by main frame RDP client modules, i.e. monitor described client
Whether machine is connected to the local bus of described main frame, if it is, main frame RDP client modules simulation client computer
Log in, and be that described client computer creates a session by terminating service module (RDP service).
The data processed result that produces for the operational order that receives from client-side about main frame is this to be treated
Output data, concrete processing procedure can be such that the behaviour assuming that user moves mouse at client-side
Making, main frame RDP client modules can obtain this operational order by the local bus of main frame, give main frame
The input processing module of terminating service module (RDP service), input processing module can obtain after processing
Obtain the action of corresponding desktop picture.Such as, if mouse is moved on certain icon by user, double-click is performed
These icons etc. operate, and terminating service module (RDP service) can be made to get mouse location information,
Know the operational order double-clicking this icon of user, and perform this operational order, produce corresponding desktop action
(such as opening the window that described icon is corresponding), then exports corresponding desktop picture to main frame RDP client
End module, and export further to client computer.
Visible, in embodiments of the present invention, owing to main frame RDP client modules can be increased in host side,
Therefore, client computer need not RDP client modules, it is possible to directly will be received by local bus
Data to be output export, such as, and content demonstrating host side etc..Obviously, in this case, right
The requirement of client capabilities is low-down, and client computer is even without the behaviour with powerful CPU and complexity
Make system, more need not set up applications, it is only necessary to pure hardware handles, it becomes possible to by defeated for treating in main frame
Go out data to be shown by display screen, or play by sound-box device, etc..Below client-side is carried out
Introduce.
Due to the data to be output of host side involved in the embodiment of the present invention can include view data or
Voice data, for client computer, outut device has only to the display device (such as display) with correspondence
Or audio-frequence player device (such as audio amplifier).Certainly, in the case of need not playing audio-fequency data, client computer
Outut device have only to display device.As long as additionally, client computer has input equipment, example again
Such as keyboard, mouse or touch pad/touch screen etc..
Certainly, in embodiments of the present invention, be connected with client computer by the local bus of main frame rather than
It is connected by network.About the local bus of main frame, in a particular application, can be usb bus (or,
Can also be FIREWIRE (1394), PCIE bus).So, client-side needs have parsing USB
The ability of agreement.And usb protocol is fairly simple, realizing easily by hardware, even input and output set
Standby can self-carried USB interface (as with the display of USB interface, mouse, keyboard etc.), even if defeated
Go out equipment self without USB interface, it would however also be possible to employ simple hardware device completes the solution of usb protocol
Analysis.That is, host-host protocol can be realized by simple hardware, without by CPU and operation system
System.By contrast, it is higher that the procotol (such as TCP/IP etc.) that parsing is complicated then needs client computer to have
Performance, this is because, realize the procotols such as TCP/IP with pure hardware extremely complex, i.e. allow to reality
Now be also required to the highest cost, and if use software realize, be just necessarily required to client-side and there is CPU
And operating system, it is clear that also cannot fundamentally reduce the cost of client computer.
It is to say, each outut device and each input equipment at client-side all have USB interface (example
As, with display, mouse or the keyboard of USB interface) in the case of, by a USB Hub (USB
Hub) each equipment is linked together.So, client computer just can be only by outut device, defeated
Enter equipment and USB connects equipment composition, if client-side has cabinet, then have only to this company
The equipment of connecing is placed in cabinet, therefore, it can be substantially reduced the cost of client computer, it is achieved truly
Thin-client.
Certainly, in actual applications, client computer can be a real physical equipment, it is also possible to if be by
The logical client of dry discrete USB device composition.Such as, these physical equipments may include that one
USB-VGA (VGA:Video Graphics Array shows drawing array) output conversion device, this turn
The effect of changing device is exactly the usb data that Receiving Host is sent, and the display that will decapsulate according to usb protocol
Data are changed, and (the interface difference of certain display device can use to be then output to VGA display device
Different conversion equipments, such as USB-HDMI or USB-DP)；These physical equipments can also include: one
Individual or multiple USB mouse or keyboard.These equipment connected by usb hub or be directly connected to main frame (or
Server) on, it is subordinate to and same session, thus logically constitutes a client computer.
It should be noted that as it was noted above, for the view data transmitted by local bus, client computer
End needs have the bitmap ability by the VGA video frequency output such as (or HDMI), by connecing over that interface
Display show.
In a word, during the embodiment of the present invention realizes remote desktop, if this locality that client computer is by main frame
Bus is connected to main frame, it is possible to the data to be output output determined by main frame, it is achieved remote desktop shows.
And in the process, client computer need not include RDP client modules, it is not required that include resolving network
The module of agreement or software, all process of client-side all can use simple hardware to complete, therefore
It is easy to reduce the cost of client computer.
The above describes a main frame and connects the situation of a client computer, in actual applications, it is also possible to
There is a main frame and connect the situation of multiple stage client computer.Now, the method utilizing the embodiment of the present invention, as long as
Multiple stage client computer is connected on main frame, and main frame by the local bus (such as USB interface) of main frame
Just can realize including multiple main frame RDP client modules (or running multiple RDP client instance).When
So, obscure in order to avoid the data to be output between multiple stage client computer, in addition it is also necessary to set up described client computer
Corresponding relation with the local bus port being connected, in order to according to described corresponding relation to from each client computer
User operation respond respectively, and data processed result is returned to respectively corresponding client computer.
Connect the situation of multiple stage client computer about an above-mentioned main frame, concrete implementation mode can have multiple,
Such as, one of which implementation method may is that
A client-side management software module is realized, when this client-side management software module is at main frame in host side
Local runtime time, a client-side management interface can be ejected.It is inserted into by USB interface when there being equipment
Time on main frame, this client-side management software module is able to detect that these equipment, and can be on this interface
Display has been inserted at the USB device list on this main frame.
Wherein, when being real physical equipment for client computer, the equipment in USB device list is corresponding
Be exactly each client computer, the user of host side can select to set up in menu the option of RDP client, visitor
Family end managing software module just can trigger the running example creating multiple RDP client modules, each example
Corresponding to a guest physical equipment.RDP client running example when some physics client computer corresponding
After being connected to RDP service, video data corresponding to this physics client computer will be output this client computer；
And the input of this client computer, RDP service process will be sent to, to produce corresponding desktop action.With
Reason, the RDP client of other logical client and correspondence thereof is operated the most in this way.
When the logical client that client computer is made up of several discrete USB devices, this client
In the USB device list that end managing software module demonstrates, display will be the most discrete USB device,
For example, it may be possible to include multiple USB video card, multiple USB sound card, multiple USB mouse, keyboard etc., it is
System possibly cannot go out the logical relation between each USB device, therefore, concrete processing method by automatic distinguishing
Can be slightly different.Concrete can be carried out as follows: the user of host side passes through mouse drag, can be USB
A USB video card, the sound card of a USB, a USB mouse and a USB in list of devices
Keyboard is put under a catalogue, and clicks on confirmation, and at this moment client-side management software just can be these four equipment
Logically it is linked together, constitutes the client computer of a logic.The input equipment of this client computer is this mouse
And keyboard, outut device is USB video card and sound card.It is similar to, it is also possible to another USB video card, separately
The sound card of one USB, another USB mouse and another USB keyboard are put under another catalogue, and
Clicking on and confirm, at this moment client-side management software just can logically be linked together this other four equipment,
Constitute the client computer of another logic, by that analogy.Then RDP client is set up during user selects menu
Option, client-side management software module just can trigger and create the operation of multiple main frame RDP client modules in fact
Example.When the running example of the RDP client modules of some logical client corresponding is connected to RDP
After service, the video data of this logical client will be output to the USB video card of this logical client；
Voice data will be output to the USB sound card of this logical client；And the USB mouse of this logical client and
The input of keyboard, will be sent to RDP service process, to produce corresponding desktop action.In like manner, its
The RDP client of his logical client and correspondence thereof is operated the most in this way.
It is further to note that be connected to the situation of a main frame, different use in aforementioned multiple stage client computer
Family operation in different client computer will not interact, and the operation in each client computer is independent.Example
As, if initially there being client computer A to be connected to main frame, a certain moment, user passes through client computer A to master
Machine has carried out certain operation so that demonstrate on the display of client computer A is no longer the main interface of this main frame；
If at this moment another client computer B is connected with this main frame by the local bus of this main frame, then visitor
On the display device of family machine B, the main interface remaining this main frame of display rather than the display of client computer A set
Standby currently displaying picture.
Visible, that the embodiment of the present invention provides remote desktop scheme based on local bus, goes for little
In type office or domestic environment, multiple users share the scene of same main frame.The advantage of this scheme is,
The complexity of client can be substantially reduced, thus be substantially reduced the cost of client, finally create for user
