Description

  The present invention relates to a plant monitoring apparatus that performs operation, control, operation, and monitoring of a plant.

  In general, in a plant monitoring apparatus such as power generation, measurement values are collected from facilities or equipment to be monitored, display information is generated based on the collected measurement values, and displayed on the display apparatus. The display information is created by dividing it into a plurality of monitoring screens according to the function and configuration. However, since the number of monitoring screens increases in a large-scale plant, the display information is classified and hierarchized by the function and configuration. The plant operator follows the hierarchy and displays a desired monitoring screen.

The plant operator who performs the operation by looking at the display device in the central monitoring room is generally an expert in monitoring work, which screen belongs to which hierarchy, and in what case which screen is viewed. I know a lot. However, a worker who performs a maintenance inspection on the site with a portable terminal such as a tablet is generally not an expert in monitoring work, and therefore does not always store the classification and hierarchical structure of monitoring functions. For this reason, in order to display a desired monitoring screen, it is necessary to acquire knowledge about the function and configuration of the plant, the hierarchical structure of the screen, and the operation method.

  In Patent Document 1, selection function information for selecting a monitoring function of a desired hierarchy from hierarchized monitoring functions is recorded in an IC tag, and the IC tag is read by a portable terminal, for example. By displaying the monitoring screen based on the information, the time required to select and display the monitoring screen is reduced.

JP2007-310802 (paragraph number 13)

  According to Patent Document 1, since a monitoring screen corresponding to a desired monitoring function can be automatically displayed by simply holding the IC tag, it is necessary for an operator to sufficiently learn the hierarchical structure and operation procedure. Absent.

  However, the information embedded in the IC tag is fixed, and only a specific monitoring screen (including the case of a plurality of images) can be selected and displayed. For example, when it is desired to select a target that dynamically changes according to the current state of the plant, such as a screen related to a currently occurring alarm, the conventional operation is required. In addition, if you want to search for monitoring screens to be displayed from various viewpoints, such as screens related to equipment to be inspected and screens related to specific input / output points, advanced knowledge of the plant and monitoring work is required.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a plant monitoring apparatus according to Embodiment 1 of the present invention. In FIG. 1, the display management unit 1 generates display information based on the screen information acquired from the screen information providing unit 5 and the plant data acquired from the plant data providing unit 6, and outputs the display information to the display device 9. How to generate the display information is determined based on the display rule extracted from the display rule storage unit 2 and the point of interest. In the drawings, the same reference numerals denote the same or corresponding parts, and this is common to the entire text of the specification and all the drawings. Furthermore, the form of the constituent elements appearing in the whole specification is merely an example, and is not limited to these descriptions.

  The display management unit 1 includes a display information generation unit 11, a focus information extraction unit 13, a display magnification calculation unit 14, and a display information update unit 12. The display magnification calculation unit 14 calculates the display magnification from the input event received from the event processing unit 7. The target information extraction unit 13 extracts target target information from the plant data and the screen information according to the display rule and the target point. Based on the screen information acquired from the screen information providing unit 5, the display information generating unit 11 generates display information in a table format with one or more monitoring screens as components. The display information updating unit 12 acquires plant data from the plant data providing unit 6 for information that needs to be updated, re-extracts attention information as necessary, and redraws the changed portion.

  In response to a request from the display management unit 1, the screen information providing unit 5 provides monitoring screen information stored in the monitoring screen information storage unit 4 and a monitoring screen image stored in the thumbnail information storage unit 3. The plant data providing unit 6 provides plant data in response to a request from the display management unit 1.

  The event processing unit 7 receives an input event generated by a user's touch operation / mouse operation / keyboard input from the input device 10 and passes it to the display management unit 1. The point-of-interest input unit 8 passes information on the input point of interest to the display management unit 1.

  In this apparatus, first, a point of interest is set. Here, the point of interest is “alarm currently occurring”. The point of interest may be input by the user by menu selection using the input device 10 or may be input by a person other than the user through a network or the like. For example, an administrator who gives a work instruction sets “work target device” as a point of interest. In addition, when there is no input, what is the point of interest may be determined in advance.

  The event input will be described by taking a user's scaling operation as an example. Multi-touch enlargement / reduction operations include pinch-out (moving two fingers apart and widening between fingers) and pinch-in (tucking two fingers together, between fingers Narrowing). Examples of pinch-in and pinch-out are shown in FIGS. In the case of a pen or mouse operation, there is selection from a menu or a button, and in the case of keyboard input, there is a numerical input to an input field.

  When an event generated from the input device 10 is transmitted to the event processing unit 7, the event processing unit 7 passes the operation type and parameters to the display management unit 1. For example, in the case of pinch-in, the type is reduced and the parameter is the finger movement distance. The display magnification calculator 14 calculates the display magnification from the type and parameter. In the case of a button or numerical input, the display magnification is the input numerical value itself.

  A display example of the monitoring screen will be described. For example, when the display magnification is 1, the monitoring screen itself (displayed in the entire display area of the monitoring screen), when the display magnification is larger than 1, an enlarged display of the monitoring screen, and when the display magnification is smaller than 1, a plurality The monitoring screen is arranged in a list. For example, in the case of a list display, when the display magnification is large (the number of component monitoring screens is about 2 to 3), the screen is displayed according to the plant data in the same manner as the monitoring screen with the display magnification of 1. Update the display. In the case of medium (several sheets), only the information of interest is emphasized and the display is updated. If it is smaller (10 or more), the display of each monitoring screen is not updated, and only the presence / absence of the information of interest is identified. These are defined in the display rules. The drawing method, the display update method, and the drawing method of the point of interest may be methods other than this example.

  A specific example of the display rule is shown in FIG. The display rule defines, for each display magnification, a screen configuration method for configuring the screen, a component monitoring screen drawing method, and a point-of-interest drawing method. In the example of FIG. 4, there are five levels depending on the display magnification. The monitoring screen displays the monitoring up to the second stage. The monitoring display is a display method in which a variable part associated with the plant data among the parts constituting the monitoring screen changes the drawing in conjunction with the change of the plant data. Examples of the variable parts include a part indicating the open / closed state of the valve (61 in FIG. 5) and a numerical part (62 in FIG. 5) that changes according to the temperature value. In the third and subsequent stages, the monitoring image is not displayed and a thumbnail image is drawn. This is because, as the reduction ratio increases, the components that make up the monitoring screen become smaller and the monitoring status becomes difficult to see, and as the number of monitoring screens increases, the number of plant data to be acquired increases and the processing load increases. Because.

  As a drawing method of the point of interest, no special display is performed for the point of interest in the first-stage same-size or larger enlarged display. This is because the monitoring screen to be browsed has already been selected. In the second stage, the monitoring screen is displayed in a reduced size, and the monitoring screen frame is highlighted with a thick colored frame so that it can be identified that the monitoring screen includes the point of interest. In the third and fourth stages, in addition to the highlight frame display, the part of interest is drawn larger on the monitoring screen. Since only the component of interest is drawn large, it is easy to identify. In the fifth stage, since more monitoring screens are arranged and the individual monitoring screens become smaller, highlighting of the component of interest is stopped, and only the highlighted frame of the monitoring screen is drawn.

  The procedure until the monitoring screen is displayed will be described with reference to the flowchart of FIG. 6, taking as an example a case where the focus is “currently occurring alarm” and the display magnification is 1. An example of the screen when the display magnification is 1 is shown in FIG. The display management unit 1 takes out the display rule corresponding to the display magnification from the display rule storage unit 2 (step S1). Based on the display rule screen composition method, a monitor screen to be displayed is determined (step S2). Here, since the display magnification is 1, there is only one target monitoring screen.

  Next, the processing of steps S4 to S9 is repeated for the monitoring screen to be displayed. In step S4, the screen information of the monitoring screen is acquired from the screen information providing unit 5. Here, since the monitor screen drawing method of the display rule is monitoring display, the monitor screen information is acquired as the screen information. When performing the monitoring display (step S5), the plant data necessary for drawing the variable part from the monitoring screen information is acquired from the plant data providing unit 6 (step S6). Here, plant data is acquired for monitoring display.

  Next, when drawing a focused point according to the focused point drawing method of the display rule (step S7), plant data related to the focused point is acquired from the plant data providing unit 6 (step S8), and the focused information is extracted. (Step S9). Here, no process is performed because the point of interest is not drawn. The processing is repeated for the number of monitoring screens (step S3), information necessary for drawing is acquired, and the screen layout is performed (step S10). Here, since one image is displayed, the target monitoring screen is simply positioned in the entire display area. Subsequently, a monitoring screen is drawn based on the acquired information (step S11). Further, the point of interest is drawn as necessary (steps S12 and S13). Here, the point of interest is not drawn.

  When plant data changes periodically or sporadically, the display on the monitoring screen is updated. The procedure for displaying and updating the monitoring screen is shown in the flowchart of FIG. When monitoring display is performed (step S21), plant data necessary for drawing variable parts is acquired from the plant data providing unit 6 (step S22), and the monitoring screen is redrawn to update the display (step S23). ).

  Next, when drawing a point of interest (step S24), plant data necessary for drawing the point of interest is acquired from the plant data providing unit 6 (step S25), and the attention information is re-extracted as necessary (step S25). Step S26), the display of the point of interest is updated (Step S27). If the point of interest is an alarm that is currently occurring, the attention information changes according to the alarm that is occurring. If the point of interest is a device subject to maintenance and inspection, the attention information does not change, so no processing is performed.

  A process when the display magnification is changed is shown. When a pinch-in is performed by a touch operation while the monitoring screen is displayed, the display information generation unit 11 superimposes and displays on the monitoring screen that the pinch-in is being performed (FIG. 8). The pinch-in event is passed to the display management unit 1 through the event processing unit 7. The display magnification calculator 14 calculates the display magnification from the finger movement amount parameter.

  Here, it is assumed that the display magnification is changed from 1 to 0.8 by the reduction operation by pinch-in. An example of the screen before and after the pinch-in operation is shown in FIG. The display management unit 1 acquires the corresponding second-stage display rule from the display rule storage unit 2. (Step S1). Subsequently, a monitoring screen to be displayed is calculated from the display area, and three monitoring screens are determined (step S2). Here, in order to perform monitoring display, monitoring screen information and plant data are obtained for the three monitoring screens in the same manner as the display magnification 1. In order to display a highlight frame on the monitoring screen when the point of interest is included, plant data related to the point of interest, that is, the currently occurring alarm is acquired (step S8), and variable relating to the currently occurring alarm is obtained as the attention information. A part is extracted as a target part (step S9).

  In the screen layout, three screens are arranged in a horizontal row (step S10). In drawing the point of interest, the frame of the monitoring screen including the part of interest is drawn with a bold line and highlighted (step S13). At the time of drawing update, re-acquisition of attention information is performed.

  When the pinch-in operation is continued and the display magnification is halved, the display rule becomes the third level. An example of the screen before and after the pinch-in operation is shown in FIG. At this time, the monitoring screen displays a thumbnail image. The thumbnail image is obtained by saving a snapshot of the monitoring screen as a still image. When making a snapshot into an image, the amount of information to be displayed is adjusted according to the reduction ratio. For example, a numerical display component that changes according to analog plant data is not drawn when the magnification is below a certain level. This is because if the reduction ratio is high, the characters are crushed and cannot be read. Since no monitoring display is performed here, plant data for drawing variable parts is not acquired.

  In the screen layout, four monitoring screens are arranged. In drawing the point of interest, in addition to highlighting the monitoring screen, highlighting of the target component is performed. Therefore, the plant data necessary for drawing the target component is acquired. When drawing the point of interest, the part of interest is drawn with a higher emphasis than the reduction rate of the monitoring screen (101 in FIG. 11). If the monitor screen is simply reduced and displayed, the display content becomes too fine and it is difficult to grasp the screen status. However, only the target component is displayed in a large size with the thumbnail image adjusted for easy viewing. This makes it easier to identify the target object.

  Further, when the pinch-in operation is continued and the display magnification becomes less than ¼, the display rule becomes the fifth level and is displayed in four horizontal rows (FIG. 12). Here, only the highlight frame display of the monitoring screen including the target object is performed without performing the monitoring display or the emphasis of the target part.

  As described above, the display management unit 1 that generates display information from the monitoring screen and outputs it to the display device 9, the configuration and drawing method of the monitoring screen of the display information according to the display magnification, and the drawing method of the point of interest are defined. A display rule storage unit 2 that stores display rules, a plant data provision unit 6 that provides measurement values from the plant in response to a request from the display management unit 1, and a thumbnail information storage unit that stores still images of screen images of the monitoring screen 3, the monitoring screen information storage unit 4 storing the monitoring screen information of the monitoring screen, and the image extracted from the thumbnail information storage unit 6 in response to a request from the display management unit or the monitoring screen information stored in the monitoring screen information storage unit 4 A screen information providing unit 5 that provides a message, an event processing unit 7 that processes an input event from the input device 10 and passes it to the display management unit 1, and sets a point of interest in the display management unit 1. And an eye-point input unit 8.

  In addition, the display management unit 1 calculates the display magnification from the input event, the display magnification calculation unit 14, the display rule taken out from the display rule storage unit 2 and the plant data acquired from the plant data providing unit 6 according to the point of interest. A focus information extraction unit 13 that extracts focus information based on the screen information acquired from the screen information providing unit 5; and a display information generation unit 11 that generates display information in a tabular format using one or more monitoring screens as components. , Including a display information updating unit 12 that acquires plant data from the plant data providing unit 6 for information that needs to be updated and updates the display, and generates display information so that the display management unit 1 can easily identify the point of interest. Therefore, since it becomes easy to identify the monitoring screen of the target object from the display information in the table format having the monitoring screen as a constituent element, it is possible to easily search the monitoring screen of the browsing target. Kill. This is because the monitoring screen is displayed as a list in a tabular format, and the target monitoring screen and the components in the monitoring screen are displayed in an easily identifiable shape according to the display magnification. In addition, even an on-site inspection / maintenance worker who is not an expert in monitoring work can easily identify a point of interest, so that a monitoring screen to be viewed can be easily searched and displayed.

  In other words, a display management unit that generates display information from the monitoring screen and outputs it to the display device, a plant data providing unit that provides plant data in response to a request from the display management unit, and a monitoring screen that is in response to a request from the display management unit A screen information providing unit that provides still image of the image and monitoring screen information of the monitoring screen, an event processing unit that processes an input event from the input device and passes it to the display management unit, and a focus that sets a point of interest in the display management unit A point input unit, a display information monitoring screen configuration and drawing method according to the display magnification, and a display rule storage unit that stores a display rule that defines the drawing method of the point of interest. A display magnification calculation unit for calculating a display magnification, a focus information extraction unit for extracting focus information from plant data and monitoring screen information according to a display rule and a focus point, A display information generation unit that generates display information in a tabular format and a display information update unit that acquires plant data and updates the display, and generates display information so that the point of interest can be easily identified. Therefore, it is possible to easily search for the monitoring screen to be browsed from the display information in the table format having the monitoring screen as a constituent element.

Embodiment 2. FIG.
FIG. 13 is a block diagram showing a plant monitoring apparatus according to the second embodiment. In FIG. 13, the display management unit 1 has a scroll control unit 15. The scroll control unit 15 receives an event related to scrolling passed from the event processing unit 7 and controls scrolling according to the presence or absence of a point of interest. The scroll control rule storage unit 16 stores a scroll control method. The target of scrolling is the screen on the display device 9.

  In general, there are normal scrolling and high-speed scrolling. Examples of normal scrolling include a slide for a touch operation (an operation of moving a finger while touching the display surface) and a drag of a scroll bar for a mouse operation. In normal scrolling, the display area is often changed while visually confirming the display contents. Examples of high-speed scrolling include a swipe of touch operation (operation to lightly touch and touch a finger) and wheel scroll (operation to rotate a wheel button of a mouse).

  An example of a swipe operation to pay to the left is shown in FIG. In high-speed scrolling, the display contents are often overlooked while scrolling quickly. Since the scrolling continues even after the finger is released, it is necessary to actively stop the scrolling, such as touching the screen or operating the mouse when a place you want to see appears while scrolling. There is a possibility of passing through the place you want to see in time or stopping scrolling in unexpected places.

  Here, an example of an operation of performing high-speed scrolling in the horizontal direction when a list of monitoring screens is displayed in a table format of four horizontal rows at the fifth level of the display rule in FIG. 4 will be described.

  An event generated by the swipe operation is passed to the display management unit 1 through the event processing unit 7. During scrolling, display information is generated according to the procedure shown in FIG. At this time, it is assumed that the focus information is included in the monitoring screen newly visualized by scrolling. FIG. 15 is a diagram in the case where the target monitoring screen 151 appears at the lower right corner of the screen by a swipe operation to pay to the left. At this time, the scroll control unit 15 controls the scrolling so that it is easy to see when the target monitoring screen is located near the center of the list display. The vicinity of the center may be just in the middle, or a position close to the middle with a layout that is easy to see in the list display. FIG. 16 shows an example in which a target monitoring screen 161 is displayed near the center.

  The scroll control unit 15 controls scrolling based on the scroll control rules stored in the scroll control rule storage unit 16. An example of the scroll control rule is shown in FIG. When the ID is 1, the scroll speed is kept as it is, and the scroll is automatically stopped when the target monitoring screen is located near the center. When the ID is 2, when the information of interest enters the visualization region, the scrolling is decelerated and then automatically stops. When the ID is 3, the scroll is decelerated until it reaches near the center position, but when it passes near the center position, the scroll speed is accelerated to the original scroll speed. Deceleration makes it easy to check the target monitoring screen, but if it is not the browsing target monitoring screen, it can be continuously searched. Since scrolling does not stop, there is no need to scroll again.

  As described above, the scroll control rule storage unit 16 storing the scroll control method and the scroll control unit 15 are provided in the display management unit 1, and the scroll control unit 15 controls the scrolling so that the monitoring screen including the point of interest is easy to see. Therefore, when searching for a monitoring screen by scrolling from many monitoring screens displayed in a tabular format, the monitoring screen including the point of interest can be easily viewed, and the monitoring screen to be browsed can be easily searched.

  In addition, since the display management unit includes a scroll control unit that controls scrolling of the screen of the display device, it is automatically performed when the target monitoring screen enters the visible region during scrolling in the list display state. By stopping or slowing down the scrolling, an effect can be obtained that a target monitoring screen can be easily found from a large number of monitoring screens. In particular, the effect is exhibited in a portable terminal such as a tablet operated by a finger.
