Description

  The present invention relates to a monitoring control system for industrial systems such as steel plants and papermaking plants, water supply and sewage systems, and other public systems, and more particularly to a screen development method for monitoring screens for monitoring the operating state of a plant and controlling equipment.

  In general, monitoring screens used in monitoring operations such as control operations using conventional plant monitoring control devices and plant state monitoring operations include various screens (plant system screens) that differ depending on the monitoring target (plant system). It is set so that it can be displayed on the display of the plant monitoring control device.

  As a method for displaying a monitoring screen in such a case, a method of selecting and switching a plant system screen from a plant system menu screen or displaying a plurality of screens simultaneously is known.

  However, in the above-described switching method of the plant system screen in the plant monitoring and control apparatus, the current plant system screen is temporarily terminated to display the next screen, and then the plant system menu screen is displayed. Since it was necessary to select the plant system screen to be monitored by switching to, the operation was complicated and the work efficiency was not good.

  Also, in the method of displaying multiple screens at the same time, the individual screen size is reduced more than necessary due to restrictions on display dimensions for displaying multiple screens and screen size restrictions to enable simultaneous layout of multiple screens. In some cases, there may be inconveniences such as overlapping between adjacent screens, hiding information on the overlapped portion, or displaying unnecessary information.

  By assigning property information related to the monitoring screen to the component set in advance for the monitoring screen as a display target component that can be displayed graphically on the monitoring screen displayed on the display for the plant monitoring control device Create an object that has a function to instruct switching of the display from the monitoring screen to another monitoring screen, paste this object at an arbitrary position on the monitoring screen, and display it on the display to execute the function of the functional object Thus, there is a monitoring screen switching method of the plant monitoring control device that controls display switching from the monitoring screen on the display to another monitoring screen (see, for example, Patent Document 1).

  These components are created by a user using a graphic drawing tool or by using an actual photographic image such as a JPG file. Also, since the screen using photographic images is two-dimensional, only the part that is reflected can be monitored, so for the monitored device that is hidden on the screen, take a picture from another angle, and this photo A monitoring screen is created from.

  The method for displaying the screen of the location to be monitored using the monitoring screen created in this way is to prepare and expand the monitoring menu screen displaying the title or image in advance for each monitoring screen. Because of this method, the geometric position of the current monitoring screen in the entire plant, that is, the positional relationship between this monitoring screen and the point to be monitored next in the entire plant. Cannot expand the screen by recognizing if there is.

In video monitoring in a conventional remote monitoring system, for example, a plurality of monitoring cameras installed in each monitoring area and a monitoring station that receives video captured by each monitoring camera are connected via a network. Then, the monitoring station cuts out images from the video of each monitoring camera at regular intervals to create thumbnail images, combines these thumbnail images and distributes them in a stream format, and the image creation processing device A terminal device that receives the composite image distributed from the mobile phone, divides the composite image into thumbnail images corresponding to each monitoring area, and displays the thumbnail images while updating them to the corresponding positions on the map. In some cases, it is possible to continuously monitor the entire status of each monitoring area (see, for example, Patent Document 2).
