1 is a schematic diagram showing the configuration of a lecture system through a network according to the present invention.

The lecture system 100 through a network according to the present invention includes a master server 110 and a plurality of slave servers 120, 130, 140. Here, the master server 110 and the plurality of slave servers 120, 130, 140... N are connected to each other through a hub, a cable, and a LAN card (not shown).

The master server 110 installs a program in which a screen multi viewer 111, a screen multi viewer 112, and a screen share 113 are integrated.

In addition, the master server 110 designates a specific group through a unique IP address assigned to each slave server 120, 130, 140 ... n by an administrator running a program, and the number and size of monitoring windows and automatic screen movement. When the screen multi viewer 111 is driven and the administrator selects a specific group, the slave server 120, 130, 140... n) attempts to connect to the screen agents 121, 131, 141 ... n1 at 1: 1 by TCP / IP, and sends an authentication message to each screen agent 121, 131, 141 ... n1 if the connection is successful. When the screen agent 121, 131, 141... N1 grants a service, image data transmitted from each slave server 120, 130, 140. Automatic screen display The monitoring window is moved sequentially according to the movement setting.

In addition, the master server 110 selects a specific slave server 130 by selecting the screen single viewer 112 while the program is running and clicking an IP input or a monitoring window of the corresponding slave server 130. Attempts to connect to the screen agent 131 of the 130 through TCP / IP, and when the connection is completed through the authentication process, the image data transmitted from the specific slave server 130 is preset in the window of the master server 110. Display in size. In this case, the error is transmitted when the image data is transmitted from the specific slave server 130 to the master server 110.

In addition, the master server 110 generates an event corresponding to a control command through a keyboard or a mouse on the screen of the specific slave server 130 displayed in the window of the master server 110 to the specific slave server 130. The image data transmitted from the screen agent 131 of the specific slave server 130 is displayed in a window.

In addition, when the master server 110 selects a specific slave server 130 by clicking the IP input or a window of the corresponding slave server 130 by selecting the screen share 113 while the program is running, the specific slave server 130. Attempts to connect to the screen share 132 of) through TCP / IP, and when the connection is completed through the authentication procedure, the screen share 132 of the specific slave server 130 transmits the image data. Then, the image data is captured by each slave server (120, 140… n) and the master server 110 and displayed in the window. Here, the master server 110 transmits the image data of the master server 110 itself to the outside when the administrator selects the master server 110 through the screen share 113, so that each slave server 120, 130 , 140... N, display image data of the master server 110. Here, the reason for capturing image data in the slave servers 120, 140... N and the master server 110 is that the slave servers 120, 140. This is because distributing the images one by one requires a lot of loading time.

Meanwhile, when the master server 110 generates an event corresponding to a control command through a keyboard or a mouse on the screen of the specific slave server 130 displayed in the window, the master server 110 transmits the event to the specific slave server 130 and the specific slave server 130. ) Captures the image data sent out from) and displays it in the window.

Hereinafter, a method of teaching through a network according to the present invention will be described in detail with reference to FIGS. 2 to 9.

〈Initial Settings and Screen Multi Viewer〉

FIG. 2 is an explanatory diagram showing how to set up a monitoring system in each slave server in a lecture method through a network according to the present invention, and FIG. 4 is an explanatory diagram showing a state of setting through the network, Figure 4 is an explanatory diagram showing the setting of the size and number of the monitoring window of the lecture method through the network according to the present invention, Figure 5 is through a network according to the present invention It is an explanatory diagram showing a state in which the screen multi viewer is driven in the lecture method, and FIG. 6 is an operation flowchart for explaining the initial setting and operation of the screen multi viewer in the lecture method through the network according to the present invention.

First, a unique IP address is assigned to each slave server (120, 130, 140 ... n) (S100). For example, the first computer 120 is assigned 111, 111, 100, the second computer 130 is 111, 111, 101, the third computer 140 is 111, 111, 102, the nth computer. Is given as 111, 111, nnn.

In this state, a program in which the screen multi viewer 111, the screen single viewer 112, and the screen share 113 are integrated is installed in the master server 110, and each slave server 120, 130, 140... N1 is installed in the master server 110. A program in which the screen agents 121, 131, 141 ... n2 and the screen shares 122, 132, 142 ... n are integrated is installed (S101).

When the installation of the program is completed, each of the slave servers 120, 130, 140... N runs the program, and as shown in FIG. 2, the assigned IP address (first computer 120 has 111, 111, 100, etc.). To the second computer 130, 111, 111, 102 for the third computer 140, 111, 111, nnn for the nth computer n, and the like. It is set (S102).

When the setting of the monitoring system is completed, the administrator runs a program on the master server 110 to designate a new group. As shown in FIG. 3, the IP address of the entire group is input, and a specific group A of all the specified groups is provided. As shown in FIG. 4, after determining the number and size of the monitoring windows, automatic screen movement (for example, four monitoring windows move from left to right every 10 seconds) is set (S103).

After all settings are completed, after the administrator drives the screen multi viewer 111 in the master server 110 (S104) and selects a specific group (A) (S105), the screen multi viewer 111 is assigned to a specific group. The screen agent 121, 131, 141… n1 of each of the slave servers 120, 130, 140... N are simultaneously attempted to connect to 1: 1 by TCP / IP (S106). If the administrator selects the screen share 113, the screen single viewer 112, etc. without selecting the screen multi viewer 111, the master server 110 processes the routine (S111).

Thus, when the connection is completed through the authentication process (S107), the screen agents 121, 131, 141 ... n1 of each slave server (120, 130, 140 ... n) transmit the image data (S108), the master server The screen multi viewer 111 of 110 masters the image data transmitted from the screen agents 121, 131, 141... N1 of each slave server 120, 130, 140... N1 as shown in FIG. 5. Each of the monitoring windows of the server 110 is displayed (S109), and the monitoring windows are sequentially moved according to the setting of the automatic screen movement (S110). Here, the screen multi viewer 111 of the master server 110 attempts to connect to the screen agents 121, 131, 141 ... n1 of each slave server 120, 130, 140. If the connection fails, wait for a predetermined time (for example, 10 seconds) (the waiting message is displayed on the monitoring window at this time) (S112), and then try to connect to the specific screen agent 141 again (S113). . Thus, when the connection is completed through the authentication process (S114), the process returns to the previous step 108 (S108), and if the connection and authentication fails, it is determined whether the predetermined number of times, that is, n times, if the number is less than n times, before the step 112 (S112) If it is returned more than n times, it is regarded as a connection failure (at this time, a connection failure message is displayed on the monitoring window assigned to the specific slave server 140).

Here, the screen agents 121, 131, 141 ... n1 of each slave server 120, 130, 140... N1 continue to display images on the screen multi viewer 111 of the master server 110 when the display screen changes. The data is transmitted so that the current screen of the slave servers 120, 130, 140... N is always displayed in the monitoring window of the master server 111.

〈Screen Single Viewer〉

7 and 8, when the administrator drives the screen single viewer 112 in the master server 110 (S200), inputting a specific IP or clicking a specific monitoring window (S201), the screen of the master server is displayed. The single viewer 112 attempts to connect to the screen agent 131 of the specific slave server 130 through TCP / IP (S202).

Thus, when the connection is completed through the authentication process (S203), the screen agent 131 of the specific slave server 130 transmits the image data of the currently displayed screen to the screen single viewer 112 of the master server 110 ( S204). Here, the screen single viewer 112 of the master server 110 attempts to connect with the screen agent 131 of the specific slave server 130 and fails to connect. After waiting for a predetermined time (for example, 10 seconds), In operation S213, a connection is attempted with the screen agent 131 again. Thus, when the connection is completed through the authentication process (S215), the process returns to the previous step 204 (S204), and if the connection and the authentication fails, it is determined whether the predetermined number of times, i.e., n times, and before the step 213 (S213). If it returns, n or more times, it is considered as a connection failure.

Then, the screen single viewer 112 of the master server 110 determines whether there is an error, that is, distortion, in the transmitted image data, and if there is no error (S205), the screen single viewer 112 displays the preset size in the window as shown in FIG. 7. (S206). If the image is distorted when the image data is transmitted from the slave server 130 to the master server 110, the screen single viewer 112 of the master server 110 sends the image to the screen agent 131 of the specific slave server 130. Performs correction by requesting retransmission of data.

In this state, when the administrator generates an event corresponding to the control command through the keyboard or the mouse on the screen of the specific slave server 131 displayed in the window of the master server 110 (S207), the screen single of the master server 110 The viewer 112 transmits this to the screen agent 131 of the specific slave server 130 (S208).

When an event is transmitted from the screen single viewer 112, the screen agent 131 transmits the corresponding event to the slave server 130, that is, the system of the third computer, so that the corresponding operation is performed (S209), and the currently displayed screen. The image data corresponding to the screen is transmitted to the screen single viewer 112 of the master server 110 (S210).

Then, the screen single viewer 112 of the master server 110 checks whether there is distortion of the transmitted image data, and if there is no distortion (S211), displays it on the window (S212).

〈Screen Share〉

In operation S302, a screen share 113 of the master server 110 attempts to connect to the screen share 122 of the specific slave server 120 through TCP / IP. Here, in addition to the master server 110, a specific slave server 120 may be selected by driving the screen shares 132, 142,... In another preset slave server 130, 140..., And the master server 110. You can also select the master server itself in.

Thus, if the connection is successful, the screen share 113 of the master server 110 transmits an authentication message to the screen share 122 of the specific slave server 120, and services the screen share 122 of the specific slave server 120. If is allowed, that is, when the connection is completed through the authentication process (S303), the specific slave server 120 transmits the video data (S304). Here, the screen share 113 of the master server 110 attempts to connect with the screen share 122 of the specific slave server 120, and if the connection fails, waits for a predetermined time (for example, 10 seconds), and then ( In step S311, a connection with the screen share 122 is attempted (S312). Thus, if the connection is completed through the authentication process (S313), the process returns to the previous step 304 (S304). If the connection and the authentication fails, it is determined whether the predetermined number of times, i.e., n times, is less than n times. If it returns, n or more times, it is considered as a connection failure.

When the image data is sent from the screen share 122 of the specific slave server 120, each of the slave server (130, 140 ... n) and the master server 110 to capture the image data and display in the window (S305).

In this state, when an event corresponding to the control command is generated through the keyboard or the mouse on the screen of the specific slave server 120 displayed in the window of the master server 110 or the designated slave server (130, 140…), (S306) The screen share 113 of the master server 110 or the screen shares 132, 142… of the designated slave servers 130, 140… transfer this to the screen share 122 of the specific slave server 120 (S307). When the event is transmitted, the screen share 122 of the specific slave server 120 transmits it to the specific slave server 120, that is, the system of the second computer, so that the corresponding operation is performed in the second computer (S308). ).

The screen share 122 of the specific slave server 120 transmits image data corresponding to the currently displayed screen (S309), and each slave server 130, 140... N or the master server 110 transmits image data. Is captured and displayed on the window (S310).
