Fig. 1 is the flow chart of the method that provides of the embodiment of the invention;
Fig. 2 is the schematic representation of apparatus that the embodiment of the invention provides.
Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The invention provides a kind of data entry device; This method is used for a main frame (being equivalent to the computer of remote desktop system as server); This main frame is connected through local bus and a client computer (being equivalent in the remote desktop system computer as client computer); Referring to Fig. 1, this method may further comprise the steps:
S101: confirm data to be exported;
S102: data said to be exported are sent to said client computer through said local bus.
Wherein, the dateout of determining for main frame of treating possibly comprise multiple situation.For example, when client computer begins to be connected to main frame, need main interface (desktop) video data of main frame be exported to client computer, so that on the display device of client computer, demonstrate the desktop of main frame.After the desktop video data was sent to client computer, the user just can see the desktop of main frame on the display device of client-side, just can utilize input equipments such as mouse, keyboard then, carried out operations such as rolling mouse, click at client-side.In the process of carrying out this operation; Need obtain the operational order that the user operates at client-side through local bus by main frame and (comprise the particular type of mouse position, action etc.; Wherein, the particular type of action comprises the clicking of mouse, double click operation etc.), then this operational order is handled; Produce result, this result need send to client-side.At this moment, treat that dateout comprises that also main frame is directed against the data processed result that the operational order that receives from client-side produces.
For common remote desktop system; Need sign in to the RDP service (terminating service module of host side by the RDP client modules that is installed in client-side; Allow the multidigit user terminal to connect and the use main frame; And on remote computer, show desktop and application program; Be the foundation structure of remote desktop, user's conversion fast, remote assistance and terminal server), RDP service just can create a Session (session) for this client computer then, under the state of this session persistence, carries out the mutual of data.And in embodiments of the present invention; For the complexity and the cost that reduce client-side, client-side does not comprise the RDP client modules, as if the scheme according to prior art; Client computer can't directly sign in to the RDP service of main frame, and then follow-up operation also just can't be accomplished.
For this reason; The embodiment of the invention provides following solution: increase main frame RDP client modules in host side; When the local bus of client computer through main frame is connected to main frame; At first initiate login (promptly simulating of the login of client computer RDP client modules) to the terminating service module (RDP service) of host side to the terminating service module (RDP service) of host side by this main frame RDP client modules; Like this; Terminating service module (RDP service) will be created a session for client computer, confirms data to be exported (for example main frame desktop video data), and terminating service module is issued main frame RDP client modules with data said to be exported then; Main frame RDP client modules further sends to client computer through local bus with data said to be exported afterwards, just can demonstrate data said to be exported (for example main frame desktop) on the client-side display device that comprise or that further connect like this.
Wherein, With data to be exported is that view data to be exported is an example; Image said to be exported is that terminating service module (RDP service) is a series of continuous desktop picture bitmap of the demonstration generation of a session; Terminating service module (RDP service) sends to main frame RDP client modules to these bitmaps through session, main frame RDP client modules and then these bitmaps are sent to client computer through local bus.
Wherein, be the operation that client computer is created session for main frame RDP client modules, can trigger by external data, for example, press the Menu key modes such as (software keys or hardware button) of certain appointment by the user; In embodiments of the present invention; Can also monitor automatically by main frame RDP client modules; Promptly monitor said client computer and whether be connected to the local bus of said main frame; If main frame RDP client modules is simulated client logon, and create a session for said client computer by terminating service module (RDP service).
About data processed result this treat dateout of main frame to the operational order generation that receives from client-side; Concrete processing procedure can be following: suppose that the user carries out the operation of rolling mouse at client-side; Main frame RDP client modules can obtain this operational order through the local bus of main frame; Give the input processing module of the terminating service module (RDP service) of main frame, can obtain the action of corresponding desktop picture after input processing module is handled.For example, if the user moves to mouse on certain icon, carry out operations such as double-clicking this icon; Can make terminating service module (RDP service) get access to mouse location information; Know the operational order of this icon of double-click of user, and carry out this operational order, produce corresponding desktop action (such as opening the corresponding window of said icon); Export corresponding desktop picture then and give main frame RDP client modules, and further export to client computer.
It is thus clear that, in embodiments of the present invention, owing to can increase main frame RDP client modules in host side; Therefore, do not need the RDP client modules on the client computer, just can directly the dateout of treating that receives through local bus be exported; For example, demonstrate the content or the like of host side.Obviously, in this case, be low-down to the requirement of client capabilities; Client computer even need not have powerful CPU and complicated operations system; More do not need set up applications, only need pure hardware handles, just can the dateout of treating in the main frame passed through display screen and show; Perhaps pass through the audio amplifier device plays, or the like.Introduce in the face of client-side down.
Because the dateout of treating of related host side can comprise view data or voice data in the embodiment of the invention, for client computer, output equipment only need have corresponding display device (like display) or audio-frequence player device (like audio amplifier).Certainly, under the situation that does not need playing audio-fequency data, the output equipment of client computer only needs display device to get final product.In addition, client computer is as long as have input equipment, for example keyboard, mouse or touch pad/touch-screen or the like again.
Certainly, in embodiments of the present invention, be that the local bus through main frame links to each other with client computer, rather than link to each other through network.About the local bus of main frame, in concrete the application, can be usb bus (perhaps, also can be FIREWIRE (1394), PCIE bus).Like this, client-side need have the ability of resolving usb protocol and gets final product.And usb protocol is fairly simple; Realize through hardware easily; Even input-output equipment can the self-carried USB interface (as having display, mouse, keyboard of USB interface etc.); Even output equipment self does not have USB interface, also can adopt simple hardware device to accomplish the parsing of usb protocol.Also promptly, can realize host-host protocol through simple hardware, and need be by CPU and operating system.By contrast; Resolving complicated procotol (like TCP/IP etc.) then needs client computer to have higher performance, and this is because realize very complicacy of procotol such as TCP/IP with pure hardware; Even also needing can realize very high cost; And if employing software is realized, just must need client-side to have CPU and operating system, obviously also can't fundamentally reduce the cost of client computer.
That is to say all have under the USB interface situation of (for example, having display, mouse or the keyboard of USB interface) at each output equipment and each input equipment of client-side, through a USB Hub (usb hub) each equipment being linked together gets final product.Like this, client computer just can only be made up of output equipment, input equipment and USB connection device, if client-side has cabinet; So only need this connection device be placed in the cabinet and get final product; Therefore, can reduce the cost of client computer greatly, realize thin-client truly.
Certainly, in practical application, client computer can be a real physical equipment, the logical client that also can be made up of several discrete USB devices.For example; These physical equipments can comprise: a USB-VGA (VGA:Video Graphics Array; Show the drawing array) output conversion device, the effect of this conversion equipment is exactly to receive the usb data that main frame is sent, and will change according to the video data of usb protocol decapsulation; Export to VGA display device (the interface difference of display device can be used different conversion equipments certainly, such as USB-HDMI or USB-DP) then; These physical equipments can also comprise: one or more USB mouses or keyboard.These equipment connect through usb hub or are directly connected on the main frame (or server), are subordinate to and same session, thereby from constituting a client computer in logic.
Need to prove that of preamble, for through local bus image transmitted data, client-side need have the ability of bitmap through VGA (or HDMI etc.) video output, is shown by the display that is connected on this interface.
In a word, the embodiment of the invention realizes that in the process of remote desktop, the local bus that client computer needs only through main frame is connected to main frame, just can the dateout of treating that main frame is determined be exported, and realizes that remote desktop shows.And in this process, client computer need not comprise the RDP client modules, need not comprise the module or the software of resolving procotol yet, and all processing of client-side all can adopt simple hardware to accomplish, and therefore is convenient to reduce the cost of client computer.
The situation that the above has introduced a client computer of a main frame connection in practical application, also possibly exist a main frame to connect the situation of many client computer.At this moment, utilize the method for the embodiment of the invention,, and comprise on the main frame that a plurality of main frame RDP client modules (or moving a plurality of RDP client instances) just can realize as long as the local bus (for example USB interface) of many client computer through main frame is connected to main frame.Certainly; The dateout of treating for fear of between many client computer is obscured; Also need set up the corresponding relation of said client computer and the local bus port that is connected; So that according to said corresponding relation the user's operation from each client computer is responded respectively, and data processed result is returned to corresponding client computer respectively.
About the situation of many client computer of above-mentioned main frame connection, concrete implementation can have multiple, and for example, wherein a kind of implementation method can be:
Realize a client-side management software module in host side, when the local runtime of this client-side management software module, can eject a client-side management interface at main frame.When equipment was inserted on the main frame through USB interface, this client-side management software module can detect these equipment, and can show the USB device tabulation that has been inserted on this main frame on this interface.
Wherein, For client computer is the situation of real physical equipment; What the equipment in the USB device tabulation was corresponding is exactly each client computer; The user of host side sets up the option of RDP client in can choice menus, and the client-side management software module just can trigger the running example of creating a plurality of RDP client modules, and each instance is corresponding to a client computer physical equipment.After the RDP client running example of the some physics client computer of correspondence was connected to RDP service, the corresponding video data of this physics client computer will be by this client computer of output; And the input of this client computer will be sent to RDP service to handle, to produce corresponding desktop action.In like manner, other logical client and corresponding RDP client thereof are all carried out work in this way.
The situation of the logical client of forming by several discrete USB devices for client computer; What show in the USB device tabulation that this client-side management software module demonstrates will be discrete one by one USB device; For example, possibly comprise a plurality of USB video cards, a plurality of USB sound card, a plurality of USB mouse, keyboard or the like, system possibly can't go out the logical relation between each USB device by automatic distinguishing; Therefore, concrete processing method can be slightly different.Concrete can carry out as follows: the user of host side pulls through mouse; Can be put into a USB video card, the sound card of a USB, a USB mouse and the USB keyboard in the USB device tabulation under the catalogue; And click and confirm; At this moment client-side management software just can logically be related to these four equipment together, constitutes the client computer of a logic.The input equipment of this client computer is this mouse and keyboard, and output equipment is USB video card and sound card.Similarly; Can also be put into the sound card of another USB video card, another USB, another USB mouse and another USB keyboard under another catalogue; And click and confirm; At this moment client-side management software just can other logically be related to this together by four equipment, constitutes the client computer of another logic, by that analogy.Set up the option of RDP client then in user's choice menus, the client-side management software module just can trigger the running example of creating a plurality of main frame RDP client modules.After the running example of the RDP of the some logical client of correspondence client modules is connected to RDPservice, the video data of this logical client will be outputed to the USB video card of this logical client; Voice data will be outputed 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 to handle, to produce corresponding desktop action.In like manner, other logical client and corresponding RDP client thereof are all carried out work in this way.
Need to prove that in addition be connected to the situation of a main frame in aforementioned many client computer, the operation of different users on different client computer can not interact, the operation on each client computer all is independently.For example, if there is a client computer A to be connected to main frame at first, in a certain moment, the user has carried out certain operation through client computer A to main frame, makes that what demonstrate on the display of client computer A no longer is the main interface of this main frame; If at this moment another client computer B is connected with this main frame through the local bus of this main frame, the main interface that remains this main frame that then on the display device of client computer B, shows, rather than the current picture displayed of the display device of client computer A.
It is thus clear that the remote desktop scheme based on local bus that the embodiment of the invention provides goes in minimized office or the domestic environment, a plurality of users share the scene of same main frame.The advantage of this scheme is, can reduce the complexity of client greatly, thereby reduce the cost of client greatly, and finally be user's creation of value.
In order to understand the technical scheme that the embodiment of the invention provides better, at length introduce from application point of view with the example in the practical application below.
On the main frame that is provided with a terminating service module (RDP service); A main frame RDP client modules is set; The function that replaces being installed in originally the RDP client modules on the client computer by this main frame RDP client modules; Terminating service module on main frame (RDP service) is initiated login, and sets up session (session).In concrete processing procedure, mainly can following steps:
Step 1: when client computer is connected on the local bus of main frame, triggers main frame RDP client modules and start operation, initiate logging request to terminating service module (RDP service);
Step 2: terminating service module (RDP serrvice) responds the login of this main frame RDP client modules, creates a RDP session;
Login process comprise with client logic on be connected, and to authentication of client computer or the like;
Step 3: terminating service module (RDP service) sends to this main frame RDP client modules with the corresponding video data of this session (session);
Step 4: this main frame RDP client modules sends to client computer with video data through local bus;
Demonstrate the main interface (being desktop) of main frame on the display device that this moment, client-side comprised or connect, the user can carry out operations such as mouse-keyboard;
Step 5: when user's executable operations, this main frame RDP client modules receives the operation input information from client computer through local bus, and this input information is sent to terminating service module (RDPservice);
For example, user's operation possibly be a rolling mouse, and what this main frame RDP client modules obtained is the input information that has cursor position information, and sends to terminating service module (RDP service);
Step 6: terminating service module (RDP service) is according to the input information that receives; Other assemblies on host operating system are handled input information; The corresponding desktop window that produces changes;, and the desktop video data that will upgrade this moment sends to this main frame RDP client modules;
Step 7: this main frame RDP client modules sends to client computer with video data through local bus, and the display device that is comprised by client-side or connect shows.
It is thus clear that main frame RDP client modules receives the input of client, is transmitted to terminating service module (RDP service); And then the desktop video data of the renewal that produces terminating service module (RDP service) to this input, being transmitted to client computer, the display device through client-side shows.Like this, the user of operation client computer is like having a computer that oneself exclusively enjoys.
As previously mentioned, can have a plurality of such main frame RDP client modules on the main frame, and connect a plurality of client computer simultaneously.Each main frame RDP client modules all links to each other with a client computer, and like this, the user who operates each operation client computer seems to have a computer that oneself exclusively enjoys.
In a word; The embodiment of the invention is through operating in the RDP client modules on the have terminating service module main frame of (RDP service); Give client computer by this RDP client modules handle that operates on the main frame from the video data of terminating service module (RDP service) then, send to terminating service module (RDP service) to input information from client computer.Like this, just can not comprise any additional modules on the client computer or any software is not installed only have the most simply demonstration and mouse/keyboard input function and get final product.And then client computer just can be done very simply, and cost is very low.
