  The display information updated in the display information generation unit 26 is transmitted to the portable terminal 40 via the terminal communication interface unit 24 and the network 30 (S10).

  The updated display information transmitted from the monitoring server 20 is received by the server communication interface unit 43 of the portable terminal 40 and displayed on the display unit 44 (S11). An example when the updated display information is displayed on the display unit 44 is shown in FIG.

  In FIG. 5, among the display information generated as shown in FIG. 4, the numerical symbol corresponding to the dial button “2” operated by the monitor is enlarged and displayed as the numerical symbol 12a. At this time, the numerical symbol 12a is displayed in the vicinity of the position where the numerical symbol 2a before enlargement was displayed, so that the supervisor recognizes that the numerical symbol 2a has been enlarged.

  When the numerical symbol selected in this way is enlarged and displayed, the process value displayed in the frame of the numerical symbol is easily visible.

  According to the above embodiment, the process flow screen generated in the monitoring server is displayed on the display screen of a general-purpose portable terminal, and the process value of the desired plant can be easily enlarged and displayed with a simple operation. it can. Therefore, in the plant monitoring information display system of this embodiment, it is not necessary to install a program dedicated to process flow screen display for plant monitoring on each portable terminal, and general graphic processing and transmission / reception processing with a monitoring server can be executed.

  In the state where the screen configuration information is stored in the portable terminal 40 as described above, monitoring information such as process values in the plant is displayed on the portable terminal 40 in an emergency such as a periodic inspection of the plant or when an abnormality occurs. The processing when it is displayed on the unit 44 and provided to the supervisor will be described with reference to the sequence diagram of FIG.

  In FIG. 8, since the process of step S21-S25 is the same as the process of step S1-S5 in 1st Embodiment, detailed description is abbreviate | omitted.

  When the monitoring server 20 receives the monitoring information request transmitted from the portable terminal 40 via the terminal communication interface unit 24, the process value extraction unit 25 obtains the latest process value at the location specified by the monitoring information request. Extracted from the process value storage unit 23.

  The process value extracted by the process value extraction unit 25 is transmitted to the portable terminal 40 via the terminal communication interface unit 24 and the network 30 (S26).

  The process value transmitted from the monitoring server 20 is received by the server communication interface unit 43 of the mobile terminal 40 (S27), and the display information generation unit 46 uses the screen configuration information stored in the screen configuration information storage unit 45. Display information of a process flow screen in which the received process value is graphically superimposed on a screen showing a process flow using icons and numerical symbols is generated.

  The display information generated by the display information generation unit 46 is displayed on the display unit 44 as shown in FIG. 4 (S28).

  As in the case of the first embodiment, when the dial button “2” in the dial button unit 41 corresponding to the process value to be confirmed by the monitor is operated, the operation content is acquired by the operation button information acquisition unit 42. Then, it is sent to the display information generation unit 46 (S29).

  When the information on the dial button “2” operated by the monitor is acquired from the operation button information acquisition unit 42, the display information generation unit 46 expands the numerical symbol 2a corresponding to the information on the dial button “2”. The display information is updated so that it is displayed.

  The display information updated in the display information generation unit 46 is displayed on the display unit 44 as shown in FIG. 5 (S30).

  According to the above embodiment, the process value of the desired plant can be easily enlarged and displayed on the process flow screen displayed on the display screen of the portable terminal with a simple operation. In the present embodiment, a general-purpose device can be used as long as it is a terminal having a program recording and operation function that meets a required condition, such as a mobile phone terminal capable of installing a game program.

  In the plant monitoring information display system according to this embodiment, there is no need to transmit / receive display information (image information) between the monitoring server and the mobile terminal, and the amount of data to be transmitted / received is reduced compared to the case of the first embodiment. In addition, if a standardized process flow display program is installed in the portable terminal in advance, it is possible to reduce the load of display processing for customization. As a typical technique for operating the mobile terminal according to the second embodiment, there is a method of combining a JAVA applet and an XML format.

  In the screen configuration information of the plant monitoring information display system according to the present embodiment, the case has been described in which numerical symbol frames and dial button display buttons are distinguished only by color. However, in the XML format screen configuration information, the monitoring server 20 and the mobile phone are displayed. By preliminarily negotiating the color code with the terminal 40, it is possible to set information for distinguishing the frame of the numerical symbol and the corresponding button display more variously than the HTML format standard.

  For example, it is possible to set in a simple format that different colors are used depending on the presence or absence of blinking, such as continuous red lighting and red flashing lighting. When the number of numerical symbols to be displayed is large and the corresponding dial buttons are also large (up to 12 in the case of the dial buttons in FIG. 2), it is difficult to differentiate by visual recognition only by identifying colors. By setting decoration information such as the presence or absence of blinking as described above, it becomes possible to distinguish the frame of the numerical symbol and the display of the dial button with a small number of color information, and by the visual of the observer Color judgment mistakes can be avoided.

  In the first embodiment and the second embodiment described above, a case has been described in which a corresponding dial button is selected by selecting a process value to be confirmed. A desired numerical symbol may be selected from a process flow screen displayed by using a sub-dial for specifying up, down, left, and right provided in the mobile phone terminal, and the selected numerical symbol may be enlarged. . At this time, the numerical symbols displayed by operating the sub dial can be selected in order from the upstream of the process flow, and if you want to select the numerical symbol at the skipped position, You may make it selectable by operating the dial button corresponding to the color of a frame.

  In the first and second embodiments described above, the case where the enlarged numerical symbol is displayed in the vicinity of the display position of the numerical symbol before enlargement has been described. However, the present invention is not limited to this. 9 (a) is displayed at the center of the process flow screen, or as shown in FIG. 9 (b), it is displayed at the edge of the screen or in a blank area so as not to disturb the display in the process flow screen. You may make it do.

  In the first embodiment and the second embodiment described above, the dial button display displayed by the dial button display information corresponds to the numeric keypad arrangement of a general-purpose mobile phone terminal as shown in FIGS. Although the case where it is displayed in the format has been described, the present invention is not limited to this, and the dial buttons may be displayed side by side as shown in FIG.
