Embodiment
As stated in the Background Art, the mode of existing use TELNET/SSH or Telnet is accessed in the scheme of remote virtual machine, require that user has a physical computer, corresponding access or control operation could be realized, and the cost of physical computer drops into, the not factor such as portability and running environment demand, all limits the access of remote virtual machine or control, have impact on the realization carrying out remote virtual machine accessing operation whenever and wherever possible.
For above-mentioned problem, the present invention proposes a kind of scheme of carrying out remote virtual machine access by existing display device, do not need configures physical computing machine, just can be accessed the remote virtual machine of oneself by existing display device (as televisor, handheld terminal etc.) and network (cable network and wireless network) whenever and wherever possible.
As shown in Figure 1, for the schematic flow sheet of a kind of long-range control method proposed by the invention, be applied in the system at least comprising display device, input equipment, connector and remote virtual machine, wherein, connector is connected with remote virtual machine with display device, input equipment respectively, and the method specifically comprises the following steps:
Step S101, when connector starts, connector generates log-on message User Interface, and is shown by display device.
It is to be noted, above-mentioned generation log-on message User Interface, it can be the local Interface debond operation performed after connector starts, also can be store a log-on message User Interface in advance in the connectors, after connector starts, directly display device is sent to show the log-on message User Interface prestored.
Due to corresponding interface formats and the contents of a project that comprise relatively fixing; and generating mode is simple; therefore; the local Interface debond operation that concrete employing is above-mentioned; or adopt the interface operation that prestores to adjust according to the actual needs, such change does not affect protection scope of the present invention.
Step S102, connector receive the information corresponding with each entry in log-on message User Interface that input equipment sends, and are shown in log-on message User Interface by display device.
In concrete enforcement scene, above-mentioned procedure for displaying is actual is directly transmitted to display device by the information that input equipment inputs for connector, and corresponding position directly shows in log-on message User Interface.
In such processing procedure, the information that connector is equivalent to being inputted by input equipment directly forwards to display device, to carry out the display of corresponding information input condition in the display device.
When connector receives the connection request of input equipment transmission, connector determines whether each entry in current log-on message User Interface has all been filled in.
If judged result is yes, perform step S103.
If judged result is no, then show corresponding information in the display device, prompting proceeds filling in of log-on message, or is pointed out by corresponding prompt tone, returns step S102 afterwards and proceeds corresponding Information Inputting Process.
The login request message of the information of carrying each entry sends to the remote virtual machine corresponding to connection request to verify by step S103, connector.
In order to ensure that the result of login authentication can not be interfered because of the ruuning situation of network traffic conditions or virtual machine, can arrange the corresponding response time in connector, concrete judgment rule is as follows:
(1) if connector judges the response message not receiving remote virtual machine in Preset Time, the connection failure of connector determination remote virtual machine.
In the case, can be shown the hint image of connection failure by display device, this picture can be preset equally in the connectors, when connector judges remote virtual machine connection failure, sends this hint image and shows to display device.
(2) if connector receives the response message of remote virtual machine in Preset Time, connector identifies the content of response message further.
When connector identification response message is login success message, perform step S104.
When connector identification response message is login failure message, connector is by the hint image of display device display login failure.
In above-mentioned situation, operation interface is that remote virtual machine returns to connector, connector sends to display device to show after extracting this interface, and the hint image of login failure can be pre-set in connector, when connector identification response message is login failure message, display device is sent to show the hint image of default login failure, also can be carried in login failure message by remote dummy equipment and send to connector, after connector receives login failure message, the hint image of corresponding login failure is obtained from this message, display device is sent to show.
Above-mentioned method of carrying corresponding hint image by response message can be avoided arranging too much hint image in the connectors; save the storage resources connected wherein; the mode presetting hint image in connector then can reduce the quantity of information of carrying in response message; simultaneously for same result; different hint images can not be produced because of the arranging difference of remote virtual machine; keep the unification of display format; in the application of reality; can the corresponding scheme of selective gist according to actual needs, such change can not affect protection scope of the present invention.
Step S104, connector receive the operation interface that remote virtual machine returns, and are shown by display device.
Concrete, above-mentioned operation interface is carried in other message that the response message returning to connector or the remote virtual machine received send to send to connector, after connector judges that response message is specially login success message, obtain the operation interface carried in the message of this login success message or the transmission of follow-up remote virtual machine, and shown by display device.
So far, complete the login process of remote virtual machine, follow-up access and the control operation can carrying out remote virtual machine according to the prompting of corresponding operation interface, namely perform step S105.
The operation instruction that the input equipment received sends directly is sent to remote virtual machine by step S105, connector, and receives the operating result that remote virtual machine returns, and connector shows corresponding operating process and operating result by display device.
In the process, connector is equivalent to the direct forward node of operation instruction, corresponding operating result and image information, itself does not carry out any process to above-mentioned information, all process operations complete by remote virtual machine, thus, weaken the processing capacity demand of connector itself to greatest extent, the configuration reducing connector needs.
After remote virtual machine is determined to login successfully, the present invention also further provides the escape mechanism of connector, specifically comprises following three kinds.
(1) escape mechanism is logged in.
When connector receives the stopping request of input equipment transmission, connector exits the login of remote virtual machine.
Exiting like this is exiting for logging status, and connector directly will stop request sending to remote virtual machine accordingly, and remote virtual machine optionally retains corresponding working site, and cuts off the communication connection between connector.
(2) remote virtual machine shutdown mechanism.
When connector receives the virtual machine turn-off request of input equipment transmission, connector forwards virtual machine turn-off request to remote virtual machine, receives the interface of the shutdown process that remote virtual machine returns, and shows in the display device.
Because remote virtual machine is closed, register before can be terminated and exit naturally.
The proposition of this mechanism can save corresponding energy consumption further, when not needing remote virtual machine to work on, remote virtual machine can be closed, continue to avoid remote virtual machine to open the energy ezpenditure caused, in the process, connector is the forward node of virtual machine turn-off request, be also the forward node of closing picture, but itself can not process operation accordingly simultaneously.
(3) improper escape mechanism.
Above-mentioned two kinds of modes be all based on normal control that instruction carries out exit process, but in the application scenarios of reality, due to some emergency case, often cause the improper interruption connected, the fault of the fault of such as connector itself or power breakdown, remote virtual machine itself or power breakdown, and the communication disruption etc. that network connectivity fai_lure between the two causes, all cannot ensure communication.And the normal transmission of corresponding operation instruction or result, access and the control of above-mentioned remote virtual machine cannot proceed, and therefore, the present invention it is also proposed corresponding processing mode to abnormal condition in this.
First the release time can presetting certain length is interval, keep current logging status during this period, wait for communication recovery, if it is interval to exceed this release time, being then considered as fault cannot recover, exit corresponding login process, wherein, if remote virtual machine itself does not have fault, and failure judgement cannot be recovered, the then corresponding working site of optional reservation, and cut off the communication connection between connector.
It is pointed out that above-mentioned escape mechanism can be used alone also can combinationally use, such change can't affect protection scope of the present invention.
Further, no matter adopt which kind of above-mentioned escape mechanism, namely when connector exits the login of remote virtual machine, or connector determination remote virtual machine is closed, or connector is when determining cannot be connected with remote virtual machine, for connector itself, follow-up operation can adopt any one of following situation, comprising:
Connector shuts down; Or,
Connector is by display device display log-on message User Interface; Or,
Connector is by the hint image of display device display connection failure.
On the other hand, consider that the core of technical scheme proposed by the invention is to utilize existing display device to carry out the display of corresponding information and result screen, therefore, due to the display output of existing display device, screen size, the difference of the series of displays parameters such as resolution, if do not processed accordingly, corresponding display frame is probably caused to show, or picture is out of shape, the appearance of the situations such as distortion, therefore, technical scheme proposed by the invention further proposes the display parameter that connector reports display device, remote virtual machine or virtual machine management program carry out adaptation processing according to the image information of corresponding display parameter to feedback, to ensure the normal display of picture, concrete process comprises:
Connector sends the display parameter of display device to remote virtual machine;
Connector receives the display frame adaptive according to display parameter that remote virtual machine returns, and is shown by display device.
It is to be noted; above-mentioned real reporting parameters process (login request message in such as step S103) can report in the lump when first time information reporting; also can give the correct time on having information to need each time to carry out to remote virtual machine and all once report; or set up independent display parameter and report process; report separately relevant parameter, the above-mentioned that reporting schemes of embody rule can't affect protection scope of the present invention.
It is further noted that, it is logic independently relation between above-mentioned each equipment, in the application of reality, connector can be an independently physical equipment, also a physical equipment can be integrated into display device and/or input equipment, such as be built in the display devices such as televisor, or mobile phones etc. comprise in the mobile terminal of display device and input equipment simultaneously, because the functional requirement of connector itself is very simple, therefore, can combine with the form of pluggable chip or functional module and corresponding equipment completely, and utilize the expansion interface of existing device to be connected with miscellaneous equipment accordingly, this will strengthen application scalability and the convenience of connector further, such change can't affect protection scope of the present invention.
Compared with prior art, technical scheme proposed by the invention has the following advantages:
By applying technical scheme of the present invention, introduce the forward node of connector as steering order and image information, utilize existing display device and input equipment realization to the access of remote virtual machine and control, thus, make user without the need to configures physical computing machine, only need to utilize existing display device and input equipment, even mobile terminal, just access and the control of remote virtual machine can be carried out, the cost not only reducing Long-distance Control drops into, also reduce the scene restriction demand of Long-distance Control simultaneously, make to carry out remote virtual machine access whenever and wherever possible and become possibility.
In order to set forth technological thought of the present invention further, now in conjunction with concrete application scenarios, technical scheme of the present invention is described.
The present invention proposes a kind of method by existing display device access remote virtual machine, thus make the access of remote virtual machine and control to be no longer the prerequisite of necessity with physical computer, everybody can access oneself remote virtual machine whenever and wherever possible by existing display device and network.
As shown in Figure 2, following equipment is at least comprised in the application scenarios of the technical program:
(1) input equipment.
As equipment such as keyboard, mouse, touch-screen, TV remote, be mainly used to the input of information or operation.
(2) display device.
As TV, graphoscope, screen of handheld terminal, projector etc., be mainly used to the image information showing remote virtual machine, certainly, in concrete application scenarios, if display device self has audio playing function, then can also play the audio-frequency information of remote virtual machine.
(3) remote virtual machine.
By this remote virtual machine, user can surf the Net or office etc.
Obviously, if remote virtual machine is a physical computer, technical scheme proposed by the invention is applicable equally, namely can realize access and the control of remote physical computing machine.
(4) connector.
Be the device coupled together by above-mentioned three kinds of units, its effect mainly comprises:
Receive the input information of input equipment, and this information is real-time transmitted to display device (during entry stage) or remote virtual machine (during the manipulation stage), receive the information such as audio frequency, image that returns of remote virtual machine, and this information is real-time transmitted to display device and carries out playing or showing.
In concrete application process, connector participates in calculating hardly, mainly carry out information forwarding, so to process chip, internal memory less demanding, even do not need the hard disc module in physical computer, one piece of flash memory is only needed to preserve the information such as user identity or virtual machine mark, thus also fairly simple to operating system call.
So compare with physical computing machine host, the cost of connector will reduce greatly.
In concrete application scenarios, if connector is specially the physical equipment of a platform independent, so, except above-mentioned parts, connector also at least comprises following external components:
(1) physical interface be connected with input equipment or wireless module (as bluetooth etc.).
(2) physical network interface be connected with network or wireless module (as WIFI, 3G etc.).
(3) link block of the physical interface be connected with display device or application other technologies.
In order to promote Consumer's Experience, during specific implementation, the various module on physical computer or interface can be increased on connector as required.
In concrete application scenarios, the operating system in connector can provide a management function (being managed by display device) further, can be configured, as information such as configuration of IP address the parameter of connector; Further, in order to the peripheral hardware such as USB, printer, scanner allowing virtual machine access connector end, these peripheral hardwares can be shared by the management function of connector, and shared user profile (as user name, password) etc. is set.
If above-mentioned connector is the functional module be embedded in display device or input equipment (be such as integrated in the modular unit in relevant device, or the chip etc. inserted in the Function Extension groove of relevant device), so, above-mentioned various interface or link block directly can utilize interface or the link block of embedded equipment self.
Be presented above the two kind existence forms of connector in practical application scene, concrete which kind of form that adopts can be selected according to actual needs, and such change does not affect protection scope of the present invention.
For convenience of description, independently physical equipment is below adopted to be described technical scheme of the present invention as the application scenarios of connector, specifically comprise entry stage, manipulation stage and shut-down-phase three phases, and similar with the respective handling process of the connector of the form of embedded connection existence, no longer repeat specification.
(1) entry stage
After connector normally starts, enter entry stage, corresponding processing procedure as shown in Figure 3, specifically comprises the following steps:
Step S301, connector create log-on message User Interface, and send the information at this interface to display device and show.
In the application scenarios of reality, the entry comprised in log-on message User Interface at least comprises:
(1) identification information of remote virtual machine, as IP address information etc.
(2) identity information of login user, as username and password etc.
Step S302, user use the entry information needed for input equipment input log-on message User Interface.
Above-mentioned information, by being connected between connector with input equipment, sends to connector.
Step S303, user input in the process of the information of each entry, and connector is also sent to display device in real time according to the information structuring image that user inputs and shows.
Connector does not process the input information received, and is direct composition and forwards, and whether image shown on display device can point out the corresponding entry of user to fill in complete.
Step S304, user send connection request by input equipment.
User self judges to complete filling in of entry information, when can proceed the attended operation of remote virtual machine, triggers corresponding connection request, and send to connector by input equipment.
After step S305, connector receive user's connection request, judge whether each entry information of user fills in complete.
If entry information solicitation is imperfect, then user is pointed out to re-enter or continue to fill in.
If entry information solicitation is complete, then perform step S306.
Step S306, connector send connection request to target remote virtual machine.
The identity information of above-mentioned login user is comprised in connection request.
Corresponding to (1) in aforesaid step S103, if connector does not receive response message within the response time of presetting, then represent remote virtual machine or network failure, such as, if target machine is physical equipment, be likely then because equipment is in off-mode, now, connector will send the image of time-out and the information such as audio frequency to point out user overtime or connection failure to display device.
Corresponding to (2) and (3) in aforesaid step S103, if all are normal for remote virtual machine and network, remote virtual machine will receive the connection request of the identity information comprising login user, and remote virtual machine verifies identity information.
If verification is not passed through, then remote virtual machine returns login failure information to connector, and connector is by the hint image of display device display login failure.
If verification is passed through, then remote virtual machine returns login success message to connector, and sends the operation interface of virtual machine to connector, performs step S307.
Step S307, connector receive login success message, obtain the operation interface that returns of remote virtual machine, and send this operation interface to display device and show.
After connector receives the response message of remote virtual machine, judge user's whether Successful login, if login failure, then the information such as image and audio frequency constructing login failure sends display device to and carries out showing or playing, and then reenters step S302; If logined successfully, the operation interface received is real-time transmitted to display device by connector to carry out showing or playing, and after this enters the normal manipulation stage.
It is to be noted; above-mentioned operation interface directly can be carried in login success message and send to connector; also can be carried at login success message after other message in send to connector; connector obtains operation interface from corresponding message; and send display device to and show, specifically adopt which kind of mode to transmit operation interface can't to affect protection scope of the present invention.
So far, entry stage completes, user's Successful login remote virtual machine, and shows corresponding operation interface on the display device.
It is further noted that, in concrete application scenarios, remote virtual machine can carry out unified management by virtual machine management program, and in such application scenarios, above-mentioned will be processed by virtual machine management program the process that identity information verifies:
If verification is not passed through, then return the information of login failure to connector.
If verification is passed through, then return the message logined successfully to connector.
Subsequently, virtual machine management program judges whether corresponding object remote virtual machine starts, if this remote virtual machine is not activated, then start this remote virtual machine, and the information such as image and audio frequency when being started by this remote virtual machine sends connector to, if and this remote virtual machine has been in upstate, then send the operation interface of this remote virtual machine to connector.
Such technical scheme belongs to protection scope of the present invention equally.
(2) stage is manipulated
After user logins successfully, enter the manipulation stage, concrete processing procedure as shown in Figure 4, comprises the following steps:
Step S401, user are by input equipment input information or executable operations, and corresponding information or operation instruction send to connector.
Step S402, connector send the input information of user or operation to remote virtual machine in real time.
Step S403, remote virtual machine resolve the information executable operations that receive.
The information such as image during operation and audio frequency are real-time transmitted to connector by step S404, remote virtual machine.
The information such as the image received and audio frequency are real-time transmitted to display device by step S405, connector, display device shows corresponding image, and plays corresponding audio-frequency information by self audio playing function or the audio-frequence player device of peripheral hardware that is connected to display device.
Certainly, if connector is directly connected with other audio-frequence player devices, image information also can be referred in this step to send to display device, and audio-frequency information is sent to the audio-frequence player device be connected with connector.
The information of user according to display device proceeds other operations, repeats above-mentioned step S401 to step S405, completes different Information Inputting Process or operating process with this.
(3) shut-down-phase
This stage is not the necessary stage, user can exit at any time in the process using remote virtual machine, comprise exiting initiatively (user sends exit instruction) and passive exit (situation such as connector power-off or Internet Transmission interruption) two kinds of situations, now, remote virtual machine will retain the working site of user.
And for the consideration of energy-conserving and environment-protective, the energy caused in order to avoid startup remote virtual machine lasting when unmanned use and network resource consumption, user also manually can perform the operation of closing remote virtual machine, just as closedown physical computer, therefore, the embodiment of the present invention proposes corresponding closing process, as shown in Figure 5, comprises the following steps:
Step S501, user perform power-off operation by input equipment, and shutdown instruction is sent to connector.
Step S502, connector send the power-off operation of user to remote virtual machine in real time.
Step S503, remote virtual machine perform power-off operation after resolving the information received.
Step S504, remote virtual machine (or the virtual machine management program at this remote virtual machine place) send the information such as the image of shutdown process and audio frequency to connector in real time.
The information such as the image received and audio frequency are real-time transmitted to display device by step S505, connector, display device shows corresponding image, and plays corresponding audio-frequency information by self audio playing function or the audio-frequence player device of peripheral hardware that is connected to display device.
Certainly, if connector is directly connected with other audio-frequence player devices, image information also can be referred in this step to send to display device, and audio-frequency information is sent to the audio-frequence player device be connected with connector.
Above-mentioned closing process is actually the closing process to remote virtual machine, so, to close or except whether available mode except by the respective picture (and the auditory tone cues play) shown by display device, user confirms whether remote virtual machine completes, connector equally can according to the duty of corresponding rule judgment remote virtual machine, and concrete judgment mode comprises multiple:
(1) duty of virtual machine management program proactive notification remote virtual machine.
Under the scene that there is virtual machine management program, after remote virtual machine has shut down, this remote virtual machine of virtual machine management program notice connector completes power-off operation.
(2) duty of the active inquiry remote virtual machine of connector.
If connector does not receive the information of remote virtual machine at the appointed time, then initiatively send a request with the state of inquiring about this remote virtual machine to this remote virtual machine, if this remote virtual machine duty is normal, can feed back accordingly, connector is normal according to this remote virtual machine duty of this feedback acknowledgment, on the contrary, if do not receive the feedback of remote virtual machine within certain response time, and not receiving other information of this remote virtual machine transmission, then connector confirms that this remote virtual machine is current unavailable.
Under the scene that there is virtual machine management program, if connector does not receive the information of remote virtual machine at the appointed time, then initiatively send a request with the state of inquiring about this remote virtual machine, after virtual machine management program receives this request, the state of this remote virtual machine is sent to connector, the duty of this remote virtual machine determined accordingly by connector.Such method connector equally also can obtain the information whether this remote virtual machine shuts down.
(3) connector directly judges that remote virtual machine is unavailable.
If connector does not receive the information of remote virtual machine at the appointed time, then connector thinks that this remote virtual machine or network connection are broken down, and sends the information such as the disabled image of this remote virtual machine and audio frequency directly to display device.
In the application scenarios of reality, above-mentioned any one mode can be adopted to carry out the acquisition of the duty of remote virtual machine, concrete which kind of scheme that adopts can't affect protection scope of the present invention.
Further, connector is after discovery remote virtual machine shuts down or be unavailable, and action subsequently can have multiple choices, as:
(1) connector also performs power-off operation.
If adopt this situation, so, preferably the shutdown of the shutdown of connector and remote virtual machine can be combined, what namely user triggered is the power-off operation of connector, but, in order to save Internet resources and the energy, the power-off operation (shutdown process described above) of connector direct trigger remote virtual machine before shutdown, and after remote virtual machine has been closed, just close connector, such process can effectively save Internet resources and energy resource consumption.
(2) connector returns the image information of user's login interface to display device, namely returns to the state of step S301.
