Method of establishing a management list

The present invention relates to a method of establishing a management list; in particular, the present invention relates to a method for establishing a personalized management list for a remote management system.

The Keyboard-Video-Mouse Switch (KVM Switch) allows users to control multiple controlled computers with a single keyboard, screen and mouse, saving space, energy and hardware costs. In addition, please refer to the first A picture, the IP-based KVM switch 15 further enables a user of a central control computer 30 (generally a desktop or laptop computer) to pass through The network manages a plurality of remotely controlled computers (or target computers) 20 and views the images transmitted by the controlled computers via the network. For example, in Taiwan, managers in Taiwan can remotely manage servers located in the US computer room through a networked KVM switch.

At present, a single network type KVM switch 15 may be able to manage up to 40 target computers 20. If the network PC switch is connected in series by appropriate means, the managed target computer 20 can be up to 20 Thousands of units. In order to manage these large number of target computers, the network type KVM switch 15 must appropriately provide a management interface 35 for the user U. This management interface 35 lists the status of the target computers 20 connected to all the ports, the status of these ports, and provides some management operations to allow the user U to operate.

However, as shown in FIG. A, the conventional management interface 35 lists only the names of the target computers connected to each of them based on words or numbers, which are short (limited length) characters, such as a string of words. Meta, numbers, or a combination thereof are used to describe different target computers 20. Because after all, The recognition or segmentation that the word can provide is not very obvious. Therefore, the user U may not be able to see the target computer 20 at a glance, and other shortcomings are still relatively standardized, and it is impossible to provide a more personalized effect. In addition, it must be noted that the names of different target computers 20 displayed on the management interface 35 are established by the administrator, and are not established by the user according to their preferences or cognition, so that the user often does not understand the administrator. The meaning of naming does not know how to select the target computer 20.

Referring to FIG. 1B, for the above problem, a so-called Panel Array Mode 31 or a so-called Picture-In-Picture (PIP) mode is generated, which is to use a plurality of target computers 20 A thumbnail of the output desktop image is simultaneously presented in an array in the concept of the central computer 30. The advantage is that the user of the KVM can have a clearer understanding of the segmentation of each target computer 20, and can view the desktop images of the plurality of target computers 20 at a time.

In the panel array mode, the image signal 22 of the desktop outputted by different target computers 20 is sequentially captured by the network type KVM switch 15 and transmitted to the central control computer 30 via the network after appropriate image processing or compression. The central control computer 30 decompresses and arranges them into an appropriate array. Because the formation process of the panel array mode 31 involves a scale-down process of the original image size of the desktop of the target computer 20, it consumes more resources or occupies more network bandwidth.

On the other hand, in recent years, with the rise of tablets, smart phones or other handheld mobile devices, the computer devices that can be used as consoles for networked KVM switches are no longer limited to traditional desktop computers or It is a laptop computer. That is, tablets or other handheld mobile devices can replace desktop or laptop computers as network-based KVM switches, just because tablet or other handheld mobile devices usually have smaller screen sizes. Therefore, the management interface of the desktop computer or laptop computer must be simplified, but the simplified management interface on the handheld mobile device still has the above-mentioned text, system, and can not provide more changeable individuals. The shortcomings of the effect. It is also considered to be less lively for the use of tablets or other handheld mobile devices.

For the Panel Array Mode, which can view the status of multiple target computers at a time, or the so-called Picture-In-Picture (PIP) mode, you can check it once. Look at the thumbnails of multiple target computer desktops, but the process of forming the thumbnails as described above is due to the scale-down process involving the original image for tablets, smartphones or other handheld mobile devices. It is a heavy burden, so it does not seem to be suitable for moving the panel array mode from a desktop or laptop directly to a tablet or similar mobile device. Therefore, it is necessary to propose a solution to the above problems.

It is an object of the present invention to provide a method of establishing a management list that reduces the amount of network floor usage.

Another object of the present invention is to provide a method of establishing a management list that provides a personalized function to improve user convenience.

A flow chart of an embodiment.

The invention is a method for establishing a management list, in particular, a personalized management list, which is suitable for managing a plurality of target computers in a remote management system. In a preferred embodiment, the method for establishing a management list of the present invention can be used in a system having a keyboard-Video Mouse (KVM), and the target computer includes at least a first target computer and a first Two target computers, but are not limited to this.

Please refer to the second figure, which is an embodiment of the remote management system of the present invention. In this embodiment, the remote management system includes at least one remote management device 100, wherein the remote management device 100 is configured to manage at least one target computer 200. Specifically, the present invention provides a method of establishing a personalizedized management list to meet different needs of an individual for managing a target computer, which can be displayed in a central control computer 300. The description will explain in detail various embodiments of the second to fourth embodiments of the present invention in accordance with the flow chart of the fifth figure, the method comprising at least the following steps S010 to S070.

First, as shown in the fifth figure, step S010 includes providing a remote management device. As shown in the second figure, the remote management system of the present invention includes at least one remote management device 100. In this embodiment, the remote management device 100 is preferably a network-type keyboard-Video-Mouse Switch, which can be switched between the target computers 200 to A user U can be used by the remote management device 100 to use any of the target computers 200 by the remote end. However, in other different embodiments, the remote management device 100 can also be other electronic products. In this embodiment, the target computer 200 can be a computer, a server, a device, or the like. For example, the target computer 200 can be one of a plurality of servers in a data center or a machine device on a production line in a manufacturing plant.

Step S020 includes coupling the remote management device to one of the control interfaces of each target computer. As shown in the second figure, the remote management device 100 further has a computer interface 115 and a network interface 120. The computer interface 115 is used to connect to at least one target computer 200. The network interface 120 is coupled via a network. To the central control computer 300, the central control computer 300 and the remote management device 100 can communicate according to an appropriate network communication protocol (such as a TCP/IP protocol group) to exchange images and keyboard/mouse related instructions. And data. The computer interface 115 has one or more computer ports 115a that can be connected to the target computer 200. In a preferred embodiment, the remote management device 100 is powered The brain port 115a can further have an image input terminal and a keyboard/mouse output port. The image input port is used to connect the image output port of the controlled computer 200; the keyboard/mouse output port is used to connect the keyboard/mouse input port of the target computer 200.

As shown in the second figure, the remote management device 100 is coupled to each target computer 200. In this embodiment, it is assumed that the target computer 200 is a computer or a machine device, and the remote management device 100 will be connected to the control interface of the computer or the machine device. For example, if the target computer 200 is a server, the server control interface will include at least one input/output port, such as an image signal output port, a mouse signal input port, and/or a keyboard signal input port. The video signal output port may include a video signal transmission mode such as a VGA (Video Graphics Array), a DVI (Digital Visual Interface), or an HDMI (High-Definition Multimedia Interface). In this embodiment, the control interface of the target computer or device 200 may also be connected to the remote management device 100 by using a universal serial bus (USB) or the like. For the remote management device 100, the image input port and the keyboard/mouse output may be integrated into a single port; for the target computer 200, the control interface (image output port and keyboard/mouse input port) It may also be integrated into a single port.

The difference from the general remote control software (such as Virtual Network Computer; VNC) is that the remote management device 100 is externally connected to one of the hardware devices of the target computer 200. For the target computer 200, the remote management device 100 is only a set of a keyboard, a screen, and a mouse. There is no direct connection between the two, so the remote management device 100 does not need to be attached to the target computer 200. system. Moreover, the target computer 200 does not need to install a server software similar to the VNC architecture, so even if the target computer 200 is in the BIOS stage or cannot be loaded into the operating system due to a failure, the remote management device 100 can still capture the target. The desktop image output by the computer 200 is then transmitted to the central control computer 300 in a network manner.

In another embodiment, in order to extend the distance between the remote management device 100 and the target computer 200, the remote management device 100 may include a plurality of RJ-45 connectors, each of which is used to connect the respective target computers 200. Control interface. In this embodiment, the remote management device 100 can be connected to each target computer 200 via a CAT-5 Cable or the like. That is, one of the five types of lines is connected to the remote management device 100, and the other end is connected to the control interface of the target computer 200.

Step S030 includes enabling the remote management device to be controlled by a central control computer via the network. Still referring to the second figure, the remote management device 100 can be coupled to the central control computer 300 via a network. The user U in front of the central control computer 300 can control the remote management device 100 via the network by using the central control computer 300. In this embodiment, the central control computer 300 can include electronic products such as a desktop computer, a notebook computer, a smart phone, and a tablet computer. In an embodiment, the user U can open a web browser 320 on the central control computer 300, such as Apple Computer's Safari, Google's google chrome, and Microsoft Corporation. A web browser such as Internet Explorer. In this embodiment, after the user U opens the web browser 320, the network address of the remote management device 100 can be set by the keyboard or screen touch mode at the network address input location 322 of the web browser 320. Input to web browser 320. At this time, the web browser 320 will retrieve and display a login screen 324 from the remote management device 100 via the network. Specifically, the communication method between the web browser 320 and the remote management device 100 of the present embodiment is preferably performed by a Hypertext Transfer Protocol (HTTP). After the user name and password are entered on the login screen 324 and the login is successful, the user U will be able to manage, control and operate the remote management device 100 via the network via the central control computer 300.

However, other communication protocol methods may also be used in other different embodiments. If the login program is not performed with the remote management device 100 by using the web browser, the central control computer 300 can also provide the login program according to an application. Alternatively, in this embodiment, an application program can be executed on the central control computer 300, and the user can also download the application corresponding to the remote management device 100 from the official website of Acer Automation Technology Co., Ltd. Program.

Step S040 includes causing the first or second target computer to be controlled by the central control computer via the remote management device. Specifically, taking the second figure as an example, after the user U successfully logs in to the remote management device 100 from the central control computer 300 through the network, the central control computer 300 can control the remote management device 100 while remotely managing. The device 100 also provides that the central control computer 300 can control any of the services of the target computer or device 200 connected to the remote management device 100. In other words, after successfully logging into the remote management device 100, the user U can control any of the target computers 200 through the remote management device 100 via the network. In fact, the remote management device 100 may be coupled to hundreds of target computers and/or (production line) devices 200, so that in order to more easily understand the present invention, the following The description will explain the spirit of the present invention in the manner of the first target computer 210 and the second target computer 220 in the plurality of target computers 200.

As shown in the second figure, the target computer 200 further includes a first target computer 210 and a second target computer 220, that is, the first target computer 210 and the second target computer 220 are coupled to the remote management device 100. After the user logs in successfully, the first target computer 210 and the second target computer 220 will be controlled by the remote control via the remote management device 100 by the remote control computer 300. Specifically, in an embodiment, as shown in FIG. 3A, after logging in to the remote management device 100, through the appropriate interface, the window S of the central control computer 300 can display the output of a controlled computer 200. The image (for example, its desktop), after which the user U can draw a shape B on the window S of the central control computer 300 by touch or mouse cursor, and the shape B defines a desktop of the target computer 200. A local area, and the local area can represent the target computer 200.

In this embodiment, the remote management device 100 can capture the image signal V output by the first target computer 210 (or the second target computer 220). Taking the third B picture as an example, after the user U switches to the first target computer 210, the remote management device 100 captures the image signal V of the first target computer 210 and transmits it to the central control computer 300 for display in the central control. On the window S of the computer 300. Specifically, the image signal (for example, VGA signal) output by the target computer 200 in response to the control signal of the central control computer 300 or the video signal output from the control signal not controlled by the central control computer 300 is received by the remote management device 100. The capture becomes a plurality of consecutive image frames, which are then converted into network packets and transmitted back to the central control computer 300 via the network according to an appropriate network communication protocol. And this capture may include the process of converting the analog signal to a digital signal and/or other image processing/compression steps.

In more detail, the remote management device 100 converts the image signal output by the target computer 200 into a continuous plurality of image frames (for example, 30 frames per second) according to a frequency, for example, every 30 minutes. The level of the analog image signal outputted by the control panel (image output port) of the target computer 200 is converted into a pixel value (Pixel Value) and stored in the memory to become an image frame. For example, a color depth of twenty-four bits (or 256 colors) may be used, and the pixel values corresponding to the RGB components may be zero to 255. After the central control computer 300 restores the received network packet to the image signal readable by the screen window S, the user U of the central control computer 300 can see the image output by the target computer 200 from one end of the network and control the image. Target computer 200, as if directly controlling the target computer 200. This restoration process may include the resolution of the network packet and the steps of reassembling the image data into analog signals.

On the other hand, when the user U of the central control computer 300 operates the target computer 200 via the keyboard/mouse or other control device at the end of the central control computer 300, the central control computer 300 controls the output of the keyboard/mouse. The signal is converted to a network packet in accordance with an appropriate network communication protocol (eg, including at least a portion of the TCP/IP protocol suite) for transmission to the remote management device 100 via the network. Moreover, the remote management device 100 can receive the network packet sent by the central control computer 300 via its network interface, and then convert the control signal contained in the network packet into a format readable by the target computer 200 via an appropriate component. For example, a standard USB signal or a PS/2 signal is emitted as if it were directly connected to a keyboard/mouse connected to the target computer 200. That is, the remote management device 100 can restore the network packet transmitted from the central control computer 300 to the original control signal and output it to the target computer 200 to further control the target computer 200. However, the remote management device 100 can also convert the network packet sent by the central control computer 300 into a different control signal and output it to the controlled computer 200, for example, the PS/2 keyboard/mouse signal of the central control computer 300. It is converted to a USB keyboard/mouse signal and supplied to the target computer 200. Alternatively, for example, the USB keyboard/mouse signal of the central control computer 300 is converted to a PS/2 keyboard/mouse signal and supplied to the target computer 200.

Therefore, taking the third B diagram as an example, when the user U switches to the first target computer 210 via the remote management device 100, the remote management device 100 captures the video signal V output by the first target computer 210 and The conversion process of the network packet is transmitted to the central control computer 300 via the network, so that the central control computer 300 can restore the received network packet to the image signal readable by the screen window S. That is, as shown in FIG. B, if the video signal output by the first target computer 210 is a picture of a flower, the above-mentioned program captured by the remote management device 100 and transmitted to the central control computer 300, the central control computer 300 can display the flower picture in the window S. In other words, the window S displayed on the central control computer 300 is related to the image signal captured by the first target computer 210 or the second target computer 220 after being output to the remote management device 100.

Step S050 includes circle-selecting an area on the window by using a touch control or a mouse cursor through the central control computer, so that the area becomes the first object that can represent one of the first target computers. This area may be the area that the user U is most interested in or most concerned with the target computer 200 (or device), or the part that is most representative of the target computer. Please also refer to the third B picture, in one In the embodiment, after the user U switches to the first target computer 210 (or the second target computer 220), an area A can be circled on the window S by the central control computer 300 by touch or mouse cursor. The area A becomes the first object R1 which can represent one of the first target computers 210.

Specifically, as shown in FIG. B, it is assumed that the user U circled a rectangular area A on the window S, and the picture included in the area A will become the first object R1 representing the first target computer 210. In this embodiment, the first object R1 is a static icon and can represent the first target computer 210. Thus, the user can associate the first target computer 210 with the static picture of the flower of the first object R1. However, in other different embodiments, the first object R1 may also be a dynamic picture, for example, because the image output by the target computer 200 is updated (the update frequency may be 60 to 75 Hz), the first object R1. The content displayed will also be updated. However, the frequency at which the target computer 200 is updated with the first object R1 may be the same or different. In a preferred embodiment, the frequency at which the first object R1 is updated may be lower. For another example, a continuous animation can be repeatedly played like a GIF image, such as a dynamic picture in which the flowers in the first object R1 are blown in the wind. It should be noted here that the range circled by the user U in the present invention is not limited to the rectangular area. Specifically, the area A circled by the user U may be various shapes such as a circle, an ellipse, a triangle, a polygon, and the like, and may be a regular or irregular shape.

Step S060 includes repeating steps S040 to S050 for the second target computer to generate a second object R2 to represent the second target computer 220 of the third A picture, and the second object R2 can be as shown in FIG. When proceeding from step S050 to step S060, as shown in FIG. 3B, the user U can switch to another target computer 200, such as the second target computer 220, via the remote management device 100. The user U can circle another area A (second area) on the window S of the central control computer 300 according to the foregoing procedure, so that the area A becomes a second object R2 which can represent one of the second target computers 220. In this step, the step of generating the second object R2 is actually the same as the generation of the first object R1 described above, and therefore will not be explained here. User U can continue to repeat steps S050 and S060 to generate more objects to represent more different target computers 200 until all target computers 200 have their corresponding objects.

Step S070 includes generating a management list according to the first object and the second object generated in steps S050 and S060. Please refer to Figures 4A and 4B. Figures 4A and 4B are shown. Different embodiments of the user interface of the management list L of the present invention are shown. As shown in Figure 4A, whether the central control computer 300 is an electronic product such as a desktop computer, a laptop computer, a smart phone, a tablet computer, or whether it is managed through a web browser or an application and remotely. The device 100 performs a communication connection. In this embodiment, the remote management device 100 can generate a management list L according to at least the first object R1 and the second object R2 generated by the foregoing or other objects.

For the embodiment in FIG. 4A, the central control computer 300 can divide the window S into a plurality of (for example, nine) regions to display respective objects corresponding to different target computers 200, such as the first object R1 and the second object. Object R2. In this embodiment, the remote management device 100 records the corresponding object selected by the user for all the target computers 200, and when the user wants to preview the target computer currently controlled by the remote management device 100 by the central control computer 300. In the management list of 200, the remote management device 100 transmits a management list L having the first object R1 and the second object R2 (and objects corresponding to other target computers) to the central control computer 300 for centrally controlling the computer. 300 can display the management list L. Alternatively, in this embodiment, the remote management device 100 manages the items required to generate the list L, and when the central control computer 300 requests, the objects and related instructions are transmitted to the central control through the network. The computer 300 further generates the management list L by the central control computer 300.

However, in other different embodiments, the generation of the management list L can be performed entirely by the central control computer 300. In the present embodiment, the central control computer 300 will record the corresponding items selected by the user U for all the target computers 200, and generate the management list L from these items. The central control computer 300 records the shape and size of each object (such as the first object R1 and the second object R2) and the relative position in the corresponding image of the target computer 200. In another embodiment, the management list L or the items required to form the management list L can also be uploaded by the central control computer 300 to the remote management device 100, so that the other central control computers 300 can be remotely accessed via the network. The management device 100 downloads and displays the management list L.

As shown in FIG. 4A, a plurality of different objects, such as the first object R1 and the second object R2, are displayed in the window S of the central control computer 300 to represent the first target computer and the second target computer, respectively. Although in the embodiment, the window S has only nine objects in space, the user can drag or scroll the screen of the window S by the touch method or the mouse cursor method to display the page S for display. Manage more items on the list L. In an embodiment, When the user clicks on an object on the window S (such as the first object R1 or the second object R2), the remote management device 100 transmits the image of the target computer 200 corresponding to the object to the central control computer 300. The user can start to manipulate the target computer 200. Moreover, in another embodiment, the window S of the central control computer 300 may also include a tool bar T (Tool bar). Tool example T can include buttons for the previous and next pages for displaying objects of different pages.

Please refer to FIG. 3B and FIG. 4A simultaneously. In an embodiment, the remote management device 100 may periodically or irregularly update the objects displayed by the central control computer 300. Specifically, the remote management device 100 updates the corresponding object displayed by the central control computer 300 according to the update of the image signal captured by each target computer 200. For example, if the image signal of the first target computer 210 is updated, the remote management device 100 will update the content of the first object R1 in the window S of the central control computer 300. In other words, the remote management device 100 only updates the content of the first object R1 on the central control computer 300 from the region of the updated image signal of the first target computer 210 corresponding to the region of the first object R1. In this way, the remote management device 100 does not need to encode and transmit the entire image signal of the captured target computer 200 to the central control computer 300, so the remote management device 100 only needs to correspond to the object (such as the first object R1). Or the image signal of the range of the second object R2) may be encoded/transmitted. In this way, the invention can partially display the image of each target computer 200 to achieve a reduction in the usage of the network bandwidth, and at the same time reduce the amount of image processing at the end of the central control computer 300.

Please refer to FIG. 4B, which is another embodiment of the management interface of the present invention. In this embodiment, the window S of the central control computer 300 can be divided into two areas, namely, an area for managing the list L and a part for displaying partial images of the plurality of target computers 200. Taking the fourth B picture as an example, the area of the right half belongs to the area of the display management list L, and the left part belongs to the area where the partial pictures of the plurality of target computers 200 are displayed, and the partial pictures of the plurality of target computers 200 are Arranged in a vertical column, for example, the object R1 is located above the object R2, and there are other objects below the object R2. As shown in FIG. 4B, the right half area may include the items of the management list L (eg, the first item R1, the second item R2, and other items). The user can browse or manage other objects in the list L by dragging or scrolling up and down the area of the management list L by means of a mouse cursor or touch. When the user wants to control the target computer 200 corresponding to an object in the management list L, the user can click the object in the management list L to make the central control computer 300 in the left half. The image screen of the target computer 200 corresponding to the object is displayed, and the screen size displayed in the left half area is larger than the screen size of the right half area. For example, if the user selects the first object R1 in the management list L, the central control computer 300 displays the first target computer (or device) 210 corresponding to the first object R1 in the left half of the window S. Image screen 324.
