The size information of the screen display area is calculated and rendered on the web browser 400. Further, when the size of the Web browser 400 is changed and a setting operation (described later) of the monitoring screen display area is performed, the monitoring screen display area creation unit 220 sends the size information of the monitoring screen display area to the Web browser (Cookie) And the size information of the monitor screen display area after the change is transmitted to the server device 10.

  Next, a process in which the client terminal 14 logs into the server device 10 will be described with reference to the flowchart of FIG.

  First, for example, as illustrated in FIG. 5, the client terminal 14 accesses the server device 10 with the Web browser 400 and logs in (step S <b> 101). In this case, for example, a user name and password set in advance are input and the login button 403 is pressed. When the login button 403 is pressed, for example, as illustrated in FIG. 6, login information such as a user name, a password, and a terminal ID is transmitted to the server device 10. That is, a log-in request notification is transmitted from the client terminal 14 to the server device 10 together with the ID (identification information: terminal ID) of the client terminal 14 (step S102). When the server device 10 receives the login request notification and the terminal ID, the setting file of the client terminal 14 that has transmitted the login request notification is stored in the storage unit 11 included in the server device 10 based on the received terminal ID. Is checked (step S103). If the server device 10 determines in step S103 that the setting file of the client terminal 14 that transmitted the login request notification is stored, the setting file is read from the storage unit 11 and the client terminal 14 Web A request to store the setting file in the cookie of the browser 400 is transmitted to the corresponding client terminal 14 (step S104). On the other hand, if the server device 10 determines in step S103 that the setting file of the client terminal 14 that transmitted the login request notification is not stored, for example, as shown in FIG. Is newly allocated and transmitted together with a notification that the setting file is not stored in the corresponding client terminal 14 (step S104). Note that the information on the size of the monitoring screen display area 401 is stored in the storage unit 11 when the setting is performed by the monitoring screen display area setting function.

  If it is determined in step S104 that the setting file of the client terminal 14 is stored, the client terminal 14 sets the window size of the monitoring screen display area 401 in the cookie of the Web browser 400 based on the received setting file, for example. Store information. Thereafter, the client terminal 14 checks whether the window size information of the monitoring screen display area 401 is stored in the cookie of the Web browser 400 (step S105). When performing the check in step S105, the layout display control application 202 performs, for example, a page load process for displaying a web page in the window of the web browser 400, so that the size information of the monitoring screen display area 401 is stored in the cookie. Check if it is. If the layout display control application 202 determines in step S105 that the window size information of the monitoring screen display area 401 is stored in the cookie of the Web browser 400, for example, as shown in FIG. The window size information of the monitoring screen display area 401 stored in the cookie 400 is read, and the window of the web browser 400 and the monitoring screen display area 401 are drawn (step S106). The monitoring screen display area 401 is drawn using, for example, Java (registered trademark) Applet. In this case, the window size information of the monitoring screen display area 401 is not transmitted to the server device 10 and stored. It is also possible to transmit the window size information to the server device 10 for storage.

  On the other hand, if it is determined in step S104 that the setting file of the client terminal 14 is not stored, the client terminal 14 stores the window size information of the monitoring screen display area 401 in the cookie of the Web browser 400. Is checked (step S105). If the layout display control application 202 determines in step S105 that the window size information of the monitoring screen display area 401 is not stored in the cookie of the web browser 400 (the size information of the monitoring screen display area 401 is stored in the cookie). If it is not stored, it means that the setting file is not stored in the server device 10, so that the size information of the appropriate monitor screen display area is calculated from the desktop resolution of the LCD 17, and the information is stored in a cookie). The size information (window size) of the monitoring screen display area 401 is calculated from the resolution of the above or the window size of the Web browser 400 (described later) and stored in a cookie. Then, for example, as shown in FIG. 9, the monitor screen display area 401 is drawn based on the stored cookie (step S106). In this case, the window size information of the monitoring screen display area 401 is not transmitted to the server device 10 and stored. It is also possible to transmit the window size information to the server device 10 for storage.

  Next, FIG. 10 is a diagram schematically showing a multi-window display function provided in the client terminal 14. As shown in the figure, the client terminal 14 has a multi-window display function, and displays a Web browser 400 for displaying the monitoring screen display area 401 and, for example, simultaneously displays a window 500 of another application program. can do. In addition, a monitoring screen menu area (described later) 402 is displayed on the Web browser 400.

  The Web browser 400 is activated on the client terminal 14 that displays the monitoring screen to access the server device 10 that distributes information necessary for plant monitoring, and the plant received from the server device 10 in the monitoring screen display area 401 of the Web browser 400 Etc. are displayed (described later).

  FIG. 11 is a diagram schematically showing the Web browser 400 displayed on the LCD 17 of the client terminal 14 in more detail.

  In the monitoring screen display area 401 displayed on the Web browser 400, as described above, a monitoring screen menu area that displays links to each function of the monitoring screen (for example, a graphic screen display function and a trend graph display function). 402 and a monitoring screen display area 401 for displaying the monitoring screen function selected in the monitoring screen menu display area 402. A user (for example, a plant supervisor) selects “graphics” and “trend” from the monitoring screen menu display area 402 (by pressing each button), and thereby based on the monitoring information of the plant and the like accumulated in the server device 10. Each screen with a graphic screen (a screen such as a bar graph or a circle graph) or a trend graph (a graph representing data transition such as a line graph) created in this manner can be displayed in the monitoring screen display area 401. Furthermore, alarm information to be notified when a preset threshold value is reached by the user selecting “alarm list” and “display area setting” from the monitoring screen menu display area 402 (by pressing each button). A list screen of an alarm list to be displayed and a screen (to be described later) for displaying display area settings can be displayed in the monitoring screen display area 401.

  In addition, each screen displayed by pressing each button of the monitoring screen menu display area 402 is processed by the layout display control application 202 when the process of drawing the monitoring screen display area 401 is performed. Is called. That is, first, the layout display control application 202 reads the display size information of the monitoring screen display area 401 stored in the cookie of the Web browser 400, and displays the screen at an appropriate size based on the read display size information. Do. For example, when the resolution of the LCD 17 is 1024 * 768 as shown in FIG. 11, the layout display control application 202 receives the resolution information (for example, 1024 * 768) of the LCD 17 from the OS 201 and displays it on the Web browser 400. Set the possible range. That is, the layout display control application 202 sets the displayable range of the Web browser 400 so that the Web browser 400 is displayed within 1024 * 768 which is the resolution of the LCD 17. The user can change the display size of the Web browser 400 within the set displayable range of the Web browser 400 (1024 * 768). For example, when the display size of the Web browser 400 is set as 650 * 500 by the user as shown in FIG. 11, the monitoring screen display area 401 is based on the display size 650 * 500 of the Web browser 400. Is created (calculated). That is, an area obtained by dividing the display size 650 * 500 of the Web browser 400 by 160 * 500 which is the monitor screen menu display area 402 and 650 * 50 which is the frame area of the Web browser 400 is the monitor screen display area 401. The display size is 490 (W) * 450 (H).

  As described above, when the monitoring screen display area 401 is created on the Web browser 400, the layout display control application 202 displays the size information of the display area of the monitoring screen display area 401 in cooperation with the Web browser 400. The layout display control application 202 transmits the size information of the display area of the monitoring screen display area 401 to the server apparatus 10 and stores it in the server apparatus 10 while storing it in the cookie.

  As described above, the method for determining the monitoring screen display area 401 includes a method for determining a display area by an operation of the monitoring screen display area setting function (an operation for changing the display size of the Web browser 400 by the user). As a method for determining (calculating) the monitoring screen display area 401, there is a display area determining method based on the resolution of the display device of the computer. The method for determining the monitor screen display area 401 based on the resolution of the LCD (display device) 17 of the computer is used to set the monitor screen display area 401 in a state where the display area is not determined by the monitor screen display area setting function. To do. In the determination method of the monitoring screen display area 401 based on the resolution of the LCD 17, the area is calculated as an optimized area when the Web browser 400 is displayed on the entire LCD 17. For example, as shown in FIG. 11, when the resolution of the LCD 17 is 1024 * 768 and the display area is not determined by the monitoring screen display area setting function, the Web browser 400 is displayed on the entire LCD 17. The display size of the monitoring screen display area 401 is obtained by dividing the display size 1024 * 768 of the Web browser 400 by 160 * 500 which is the monitoring screen menu display area 402 and 650 * 50 which is the frame area of the Web browser 400. 864 (W) * 718 (H).

  Next, a layout display method to which the information processing apparatus and layout display system of the present invention are applied will be described with reference to the sequence diagram of FIG.

  In a state where the Web browser 400 is displayed on the LCD 17 of the client terminal 14, for example, as shown in FIG. 13, the user presses the display area setting button in the monitoring screen menu display area 402 of the Web browser 400. (Step S201). The layout display control application 202 displays a message label 500 or a dialog or the like indicating that the display area setting button 404 is pressed after the window size of the Web browser 400 is determined in response to the notification of the pressing of the display area setting button (step) S202).

  Subsequently, when the display area setting button 404 is pressed by the user (step S203), the layout display control application 202 receives a notification that the display area setting button 404 is pressed, and displays the monitoring screen from the window size of the Web browser 400. The area 401 is calculated (step S204). For example, the layout display control application 202 calculates the monitoring screen display area 401 as vertical Y1 and horizontal X1, as shown in FIG. The layout display control application 202 transmits the information (for example, vertical Y1 and horizontal X1) of the calculated monitoring screen display area 401 to the server device 10 together with the identification information (for example, product serial number) of the client terminal 14 ( Step S206). The server device 10 stores the received information on the monitoring screen display area 401 in association with the identification information of the client terminal 14 as a setting file (step S207). The layout display control application 202 creates (draws) the calculated monitoring screen display area 401 on the Web browser 400 of the client terminal 14 (step S208).

  Next, processing when the window size of the Web browser 400 is changed by the user will be described with reference to FIGS.

  For example, as shown in FIG. 14, the user changes the window size of the Web browser 400 by moving the window frame of the Web browser 400 using a mouse pointer 501 or the like. In this case, by expanding the window size of the Web browser 400, the window size of the monitoring screen display area 401 is maintained, so that an area 403 where nothing is displayed on the Web browser 400 appears. Subsequently, as shown in FIG. 15, when the display area setting button 404 is pressed by the user, display area setting (change of the size of the monitoring screen display area 401) is started by pressing the monitoring screen display area setting button. . The client terminal 14 calculates (creates) the monitoring screen display area 401 from the window size of the Web browser 400 in response to the notification that the display area setting button 404 is pressed. For example, vertical Y2 and horizontal X2 are calculated as the expanded monitoring screen display area 401, and the calculated area is drawn as the monitoring screen display area 401. That is, the monitor screen display area 401 displayed in the vertical Y1 and horizontal X1 is drawn as a vertical Y2 and horizontal X2 area. Thereafter, the layout display control application 202 transmits vertical Y2 and horizontal X2 information as size information indicating the monitoring screen display area 401 together with the identification information of the client terminal 14 to the server device 10. The server device 10 stores the received size information of the monitoring screen display area 401 in association with the identification information of the client terminal 14 as a setting file.

  In this way, the window size of the Web browser 400 is changed while the monitoring screen display area 401 is displayed, and the display area of the monitoring screen display area 401 is calculated according to the changed size by pressing the monitoring screen display area setting button 404. And draw.

  The monitoring screen display area by the monitoring screen display area setting function is set by the above procedure.

  According to the above-described embodiment, the user (plant supervisor or the like) can freely set the monitoring screen display area on the Web browser of the client terminal. In addition to being able to draw the monitoring screen display area in accordance with the Web browser displayed by the user in any size, even when the size of the Web browser displaying the monitoring screen display area is changed, the display area setting button is pressed. Otherwise, the display size of the monitoring screen display area being displayed can be prevented from changing. For this reason, for example, in a state where a window of another application is displayed using the multi-window function while the Web browser 400 displaying the monitoring screen display area 401 is displayed on the LCD 17, for example, it is easy to see the other application. Therefore, even when the window size of the Web browser 400 on which the monitor screen display area 401 is displayed is reduced, the size of the monitor screen display area 401 is not changed without permission, and the monitor screen display area 401 is displayed. The display format of each displayed display does not collapse.

  The information processing apparatus according to the present embodiment can be realized not only by a computer but also by various consumer information processing apparatuses such as a PDA (Personal Digital Assistant). Furthermore, the function of the input control application can be realized by hardware such as a DSP or a microcomputer.

  Further, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the gist thereof in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine a component suitably in different embodiment.
