Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a schematic diagram of a remote control system 100 according to an embodiment of the invention.
As shown in fig. 1, the remote control system 100 includes a master terminal 110 and a controlled terminal 120, where the master terminal 110 and the controlled terminal 120 are arranged at different geographical locations, in other words, the controlled terminal 120 is a remote device having a certain distance with respect to the master terminal 110. The master terminal 110 may request to establish a remote communication connection with the controlled terminal 120, and after establishing the remote communication connection with the controlled terminal 120, the user of the master terminal 110 may remotely control the operating system of the controlled terminal 120 based on the control desktop.
Specifically, the master control terminal 110 and the controlled terminal 120 respectively include an operating system, and the operating system includes a corresponding control desktop. Here, the kinds of operating systems of the master terminal 110 and the controlled terminal 120 are the same. It should be understood that a control desktop is an interface provided by an operating system for an end user to interact with the operating system, and the control desktop can receive control information input by the user to communicate with the operating system. In order to distinguish the master terminal 110 from the controlled terminal 120, the control desktop of the master terminal 110 is named as a first control desktop 115, and the control desktop of the controlled terminal 120 is named as a second control desktop 125.
In an embodiment of the present invention, the operating systems of the master terminal 110 and the controlled terminal 120 may be implemented as Linux operating systems, but the present invention is not limited thereto.
According to an embodiment of the present invention, after the remote communication connection is established between the master terminal 110 and the controlled terminal 120, the controlled terminal 120 may create a sub-desktop window (hereinafter referred to as a second sub-desktop window 126) on a control desktop (a second control desktop 125) of the controlled terminal, and the second sub-desktop window 126 is nested in the control desktop 125 and may communicate with the control desktop. By creating the second child desktop window 126, the remote control command is executed at the second child desktop window 126.
In one embodiment, after the controlled terminal 120 creates the second sub-desktop window 126 on the second control desktop 125, the original control desktop 125 can jump from the original control desktop 125 to the newly created second sub-desktop window 126 as a "springboard machine" by starting the system desktop service on the sub-desktop window 126, so as to associate the second sub-desktop window 126 with the remote operation of the controlling terminal 110, and execute the remote control command on the second sub-desktop window 126.
According to an embodiment of the present invention, the master control terminal 110 may request the controlled terminal 120 to obtain information of the second sub desktop window 126 of the controlled terminal. The controlled terminal 120 sends the information of the second sub desktop window 126 to the master terminal 110 in response to the request of the master terminal 110. In this way, the master terminal 110 may generate a corresponding first sub desktop window 116 based on the information drawing of the second sub desktop window 126, and display the first sub desktop window 116 on the first control desktop 115 of the master terminal 110. Here, the first sub desktop window 116 is drawn by simulating the second sub desktop window 126 of the controlled terminal 120, and has the same content as the second sub desktop window 126 of the controlled terminal 120, so as to synchronously display the sub desktop window environment of the controlled terminal 120 on the first control desktop 115 of the master terminal 110.
It should be noted that the first sub desktop window 116 generated by the master terminal 110 is associated with the second sub desktop window 126 of the controlled terminal 120. Specifically, the user may perform a control operation and send control information, for example, perform a keyboard or mouse operation, in the first sub-desktop window 116 of the master terminal 110, and send the corresponding control information to the second sub-desktop window 126 of the controlled terminal 120 for execution, so as to control the operating system of the controlled terminal 120. That is, the master terminal 110 may control the operating system of the controlled terminal 120 based on the first sub desktop window 116. And, the main control terminal 110 may synchronously simulate and execute corresponding keyboard or mouse operations in the first sub-desktop window 116.
Further, the master terminal 110 may send control information to the controlled terminal 120 through the first sub-desktop window 116, so as to send the control information to the control desktop 125 of the controlled terminal 120, and send the control information to the second sub-desktop window 126 of the controlled terminal 120 via the control desktop 125, so as to execute a corresponding control command on the second sub-desktop window 126 of the controlled terminal 120. Thus, after the control information is sent by the main control terminal 110, the user executes the corresponding control command in the sub desktop window of the controlled terminal 120, and does not execute the control command in the original control desktop 125 of the controlled terminal 120. The user of the controlled terminal 120 can perform control operation on the original control desktop in parallel without being interfered by the main control terminal, so that the control operations of the user of the main control terminal and the controlled terminal are isolated from each other, and the control operation of the controlled terminal is not interfered by the main control terminal. Also, the controlled terminal 120 may monitor the operation of the master terminal based on the second sub desktop window 126.
The control information is, for example, control information input by a user through a keyboard or a mouse at the main control terminal 110, but is not limited thereto.
In one embodiment, the service 130 is included on the operating system of the controlled terminal 120. The operating system of the main control terminal 110 includes an application 113 corresponding to the service program 130. The application 113 of the master terminal 110 may establish a remote communication connection with the service 130 of the controlled terminal 120 in order to transmit control information to the controlled terminal 120.
In one embodiment, the application 113 of the controlling terminal 110 may establish a remote communication connection with the service 130 of the controlled terminal 120 based on the SSH protocol. In other words, the application 113 of the master terminal 110 may be implemented as an SSH application, and the service program 130 of the controlled terminal 120 may be implemented as an SSH service program 130, so that the master terminal 110 may remotely communicate with the controlled terminal 120 based on an SSH protocol. In this way, in response to a keyboard and mouse operation of the user in the first sub-desktop window 116 of the main control terminal 110, the main control terminal 110 sends corresponding control information to the service program 130 of the controlled terminal 120 through the application program 113, and then the service program 130 transmits the control information to the control desktop of the controlled terminal 120, and then the control desktop transmits the control information to the sub-desktop window, so as to implement execution of a control command corresponding to the control information in the second sub-desktop window 126 of the controlled terminal 120.
It should also be noted that the second control desktop 125 of the controlled terminal 120 is connected to the second sub-desktop window 126 based on SSH, so that the second control desktop 125 can forward the control information to the second sub-desktop window 126 after receiving the control information of the master terminal 110.
In an embodiment, the service program 130 of the controlled terminal 120 may be specifically implemented as an X Server, and the application program 113 of the master terminal 110 may be specifically implemented as an X Client. Accordingly, the application program X Client of the master terminal 110 may establish a remote communication connection with the servlet X Server of the controlled terminal 120 based on SSH-X. It should be understood that the controlled terminal 120 may perform the graphic DISPLAY based on the X Server, and the master control terminal 110 may remotely connect to the controlled terminal 120 based on the SSH-X by configuring a corresponding DISPLAY variable in the X Client to point to the X Server of the controlled terminal 120, and further may send the graphic DISPLAY request to the X Server of the controlled terminal 120, that is, the request sent by the master control terminal 110 to the controlled terminal 120 to obtain the information of the second sub-desktop window 126. In this way, the main control terminal 110 may obtain the graphic information of the second sub desktop window 126, so as to simulate and display the same graphic interface (i.e. the first sub desktop window 116 drawn by the main control terminal) as the second sub desktop window 126 on the main control terminal 110.
In one embodiment, the controlled terminal 120 creates a second sub-desktop window 126 on the control desktop 125 through Xephyr.
In an embodiment of the present invention, the operating system of the controlled terminal 120 is adapted to perform the remote control method. The remote control method 300 of the present invention will be described in detail below.
According to the remote control system 100 of the present invention, after the remote communication connection between the main control terminal and the controlled terminal is established, the nested sub-desktop window is established on the original control desktop of the controlled terminal, so that the control information sent from the main control terminal to the controlled terminal by the user can be sent to the sub-desktop window through the original control desktop of the controlled terminal, and the control command of the main control terminal is executed in the sub-desktop window. Based on that the controlled terminal executes the control command of the main control terminal in the sub-desktop window, the user of the controlled terminal can perform control operation on the original control desktop in parallel without being interfered by the control operation of the main control terminal, thereby achieving the effect of isolating the control operation of the main control terminal and the controlled terminal from each other. And the controlled terminal can monitor the operation of the main control terminal in the sub desktop window.
In one embodiment, the master terminal 110 and the controlled terminal 120 in the remote control system 100 of the present invention may be respectively implemented as a computing device 200. When the controlled terminal 120 is implemented as the computing device 200, the remote control method of the present invention is made executable in the computing device 200.
FIG. 2 shows a schematic diagram of a computing device 200, according to one embodiment of the invention.
As shown in FIG. 2, in a basic configuration 202, a computing device 200 typically includes a system memory 206 and one or more processors 204. A memory bus 208 may be used for communication between the processor 204 and the system memory 206.
Depending on the desired configuration, the processor 204 may be any type of processing, including but not limited to: a microprocessor (UP), a microcontroller (UC), a digital information processor (DSP), or any combination thereof. The processor 204 may include one or more levels of cache, such as a level one cache 210 and a level two cache 212, a processor core 214, and registers 216. Example processor cores 214 may include Arithmetic Logic Units (ALUs), Floating Point Units (FPUs), digital signal processing cores (DSP cores), or any combination thereof. The example memory controller 218 may be used with the processor 204, or in some implementations the memory controller 218 may be an internal part of the processor 204.
Depending on the desired configuration, system memory 206 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 206 may include an operating system 220, one or more applications 222, and program data 224. The application 222 is actually a plurality of program instructions that direct the processor 204 to perform corresponding operations. In some embodiments, application 222 may be arranged to cause processor 204 to operate with program data 224 on an operating system.
Computing device 200 also includes storage device 232, storage device 232 including removable storage 236 and non-removable storage 238.
Computing device 200 may also include a storage interface bus 234. The storage interface bus 234 enables communication from the storage devices 232 (e.g., removable storage 236 and non-removable storage 238) to the basic configuration 202 via the bus/interface controller 230. At least a portion of the operating system 220, applications 222, and data 224 may be stored on removable storage 236 and/or non-removable storage 238, and loaded into system memory 206 via storage interface bus 234 and executed by the one or more processors 204 when the computing device 200 is powered on or the applications 222 are to be executed.
Computing device 200 may also include an interface bus 240 that facilitates communication from various interface devices (e.g., output devices 242, peripheral interfaces 244, and communication devices 246) to the basic configuration 202 via the bus/interface controller 230. The example output device 242 includes a graphics processing unit 248 and an audio processing unit 250. They may be configured to facilitate communication with various external devices, such as a display or speakers, via one or more a/V ports 252. Example peripheral interfaces 244 may include a serial interface controller 254 and a parallel interface controller 256, which may be configured to facilitate communication with external devices such as input devices (e.g., keyboard, mouse, pen, voice input device, touch input device) or other peripherals (e.g., remote control machines, scanners, etc.) via one or more I/O ports 258. An example communication device 246 may include a network controller 260, which may be arranged to facilitate communications with one or more other computing devices 262 over a network communication link via one or more communication ports 264.
A network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, and may include any information delivery media, such as carrier waves or other transport mechanisms, in a modulated data signal. A "modulated data signal" may be a signal that has one or more of its data set or its changes made in a manner that encodes information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or private-wired network, and various wireless media such as acoustic, Radio Frequency (RF), microwave, Infrared (IR), or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
In a computing device 200 according to the present invention, the operating system 220 includes thereon a plurality of program instructions for performing the remote control method 300, which may instruct the processor 204 to perform the remote control method 300 of the present invention such that the operating system of the computing device 200 performs the remote control method 300 of the present invention.
FIG. 3 shows a flow diagram of a remote control method 300 according to one embodiment of the invention. The method 300 is suitable for execution in an operating system of a controlled terminal 120, such as the aforementioned computing device 200. The operating system of the controlled terminal 120 includes a control desktop 125, and the control desktop can receive control information input by a user and communicate with the operating system.
In an embodiment of the present invention, the operating system of the controlled terminal 120 is, for example, a Linux operating system, that is, the Linux operating system is included in the controlled terminal 120. However, the present invention is not limited thereto.
As shown in fig. 3, the method begins at step S310.
In step S310, the controlled terminal 120 establishes a remote communication connection with the master terminal 110 in response to the request for establishing a remote communication connection transmitted by the master terminal 110.
Subsequently, in step S320, the controlled terminal 120 establishes the child desktop window 126 on the control desktop 125. Here, the child desktop window 126 is nested within the control desktop 125 and can communicate with the control desktop 125.
In one embodiment, after the controlled terminal 120 creates the sub desktop window 126 on the control desktop 125, the original control desktop 125 can be used as a "springboard machine" to jump from the original control desktop 125 to the newly created sub desktop window 126 by starting the system desktop service on the sub desktop window 126, so as to associate the sub desktop window 126 with the remote operation of the controlling terminal 110, and execute the remote control command on the sub desktop window 126.
Subsequently, the master control terminal 110 may request the controlled terminal 120 to acquire information of the child desktop window 126 of the controlled terminal 120. The controlled terminal 120 responds to the request of the main control terminal for acquiring the information of the sub desktop window, and sends the information of the sub desktop window 126 to the main control terminal 110, so that the main control terminal 110 generates a corresponding first sub desktop window 116 based on the information drawing of the sub desktop window 126, and displays the first sub desktop window 116 on the control desktop (the first control desktop 115) of the main control terminal 110. Here, the first sub desktop window 116 is drawn by simulating the sub desktop window 126 of the controlled terminal 120, and realizes a synchronous display of the sub desktop window environment of the controlled terminal 120 on the screen of the master terminal 110, in the same manner as the contents of the sub desktop window of the controlled terminal 120.
It should be noted that the first sub desktop window 116 generated by the master terminal 110 is associated with the sub desktop window (the second sub desktop window 126) of the controlled terminal 120. Specifically, the user may perform a control operation and send control information, for example, perform a keyboard or mouse operation, in the first sub-desktop window 116 of the master terminal 110, and send the corresponding control information to the second sub-desktop window 126 of the controlled terminal 120 for execution, so as to control the operating system of the controlled terminal 120. That is, the master terminal 110 may control the operating system of the controlled terminal 120 based on the first sub desktop window 116. And, the main control terminal 110 may synchronously simulate and execute corresponding keyboard or mouse operations in the first sub-desktop window.
In step S330, the control desktop of the controlled terminal 120 may receive the control information sent by the master terminal 110 in the first sub-desktop window 116 thereof, and send the control information to the sub-desktop window (the second sub-desktop window 126) of the controlled terminal 120, so that the sub-desktop window of the controlled terminal 120 executes a corresponding control command based on the control information.
Thus, after the control information is sent by the main control terminal 110, the user executes the corresponding control command in the sub desktop window of the controlled terminal 120, and does not execute the control command in the original control desktop of the controlled terminal 120. The user of the controlled terminal 120 can perform control operation on the original control desktop in parallel without being interfered by the main control terminal, so that the control operations of the user of the main control terminal and the controlled terminal are isolated from each other, and the control operation of the controlled terminal is not interfered by the main control terminal. And, the controlled terminal 120 may monitor the operation of the master terminal at the created sub desktop window.
The control information is, for example, control information input by a user through a keyboard or a mouse at the main control terminal 110, but is not limited thereto.
According to one embodiment, the service program 130 is included on the operating system of the controlled terminal 120. The application 113 corresponding to the service program 130 is included in the main control terminal 110. The application 113 of the master terminal 110 may establish a remote communication connection with the service 130 of the controlled terminal 120 in order to transmit control information to the controlled terminal 120.
In one embodiment, the application 113 of the controlling terminal 110 may establish a remote communication connection with the service 130 of the controlled terminal 120 based on the SSH protocol. In other words, the application 113 of the master terminal 110 may be implemented as an SSH application, and the service program 130 of the controlled terminal 120 may be implemented as an SSH service program 130, so that the master terminal 110 may remotely communicate with the controlled terminal 120 based on an SSH protocol. In this way, in response to a keyboard and mouse operation of the user at the first sub-desktop window 116 of the main control terminal 110, the main control terminal 110 sends corresponding control information to the service program 130 of the controlled terminal 120 through the application program 113, and then the service program 130 transmits the control information to the control desktop of the controlled terminal 120, and then the control desktop transmits the control information to the sub-desktop window, so as to implement execution of a control command corresponding to the control information at the sub-desktop window of the controlled terminal 120.
It should be further noted that the second control desktop 125 of the controlled terminal 120 is also connected to the second sub-desktop window 126 based on SSH, so that the second control desktop 125 can forward the control information to the second sub-desktop window 126 after receiving the control information of the master terminal 110.
In an embodiment, the service program 130 of the controlled terminal 120 may be specifically implemented as an X Server, and the application program 113 of the master terminal 110 may be specifically implemented as an X Client.
Accordingly, the application program X Client of the master terminal 110 may establish a remote communication connection with the servlet X Server of the controlled terminal 120 based on SSH-X. It should be understood that the controlled terminal 120 may perform a graphic DISPLAY based on the X Server, and the master terminal 110 may send a graphic DISPLAY request to the X Server of the controlled terminal 120, that is, a request sent by the master terminal 110 to the controlled terminal 120 to obtain information of the second sub-desktop window 126, after the remote connection to the controlled terminal 120 based on SSH-X is performed by setting a corresponding DISPLAY variable in the X Client. In this way, the main control terminal 110 may obtain the graphic information of the second sub desktop window 126, so as to simulate and display the same graphic interface (i.e. the first sub desktop window 116 drawn by the main control terminal) as the second sub desktop window 126 on the main control terminal 110.
In one embodiment, the controlled terminal 120 creates a second sub-desktop window 126 on the control desktop 125 through Xephyr.
According to the remote control method 300 of the present invention, after the remote communication connection between the main control terminal and the controlled terminal is established, the nested sub-desktop window is established on the original control desktop of the controlled terminal, so that the control information sent from the main control terminal to the controlled terminal by the user can be sent to the sub-desktop window through the original control desktop of the controlled terminal, and the control command of the main control terminal is executed in the sub-desktop window. Based on that the controlled terminal executes the control command of the main control terminal in the sub-desktop window, the user of the controlled terminal can perform control operation on the original control desktop in parallel without being interfered by the control operation of the main control terminal, thereby achieving the effect of isolating the control operation of the main control terminal and the controlled terminal from each other. And the controlled terminal can monitor the operation of the main control terminal in the sub desktop window.
