Description

  The present invention relates to a touch operation (touch operation) on a monitor screen of a display device attached to an operator monitoring operation terminal having an operation display control function by digital processing in a plant monitoring control system that performs operation control by monitoring plant equipment. ) For a plant monitoring control touch operation system suitable for maintenance inspections and the like.

  In recent years, with the progress of digital technology, a contact operation (referred to as touch operation) is applied to many of the monitoring screens of a display device attached to an operator monitoring operation terminal in a plant monitoring control system. According to the touch operation, by touching symbols of various plant devices displayed on the monitoring screen, it is possible to instruct operations such as opening / closing of a valve and starting / stopping of a pump.

  In addition, since the system drawings of multiple plant equipment can be displayed on multiple pages on the monitoring screen, individual hard switches are used for operating instructions to valves and pumps, and water level, pressure, etc. Compared to the case where individual indicators are used for parameters, the central control room can be reduced in size as a monitoring control panel, can reduce the quantity of various plant equipment, and is equipped with an operator monitoring operation terminal Reduction in size (compacting) can be realized.

  FIG. 3 shows a plurality of plants in a plant monitoring control touch operation system to which an existing touch operation is applied (a screen monitoring operation type display device for plant monitoring control which is not a known invention but is generally known). It is the figure which illustrated the display screen for plant monitoring control (what is called a monitoring screen) of the systematic drawing concerning an apparatus.

  In this monitoring screen, a device display area 101 displaying a system drawing in which the members of the symbols of the tank 103a, the pump 104, the valve 105, and the tank 103b, which are various plant devices, are connected by a symbol of piping, The button operation area 106 which is a plant operation mode for instructing the operation to the valve 105 of the plant equipment, the automatic operation button 107, and the button display area 102 on which the opening operation button 108 is displayed is configured. .

  When the operator (operator) causes the operation of the valve 105 to be executed by an operation instruction as the operation control on the monitoring screen, first, when the symbol of the valve 105 in the device display area 101 is touched, the valve as shown in the button display area 102 is displayed. Since the close operation button 106, the automatic operation button 107, and the open operation button 108, which are plant operation modes for 105, are displayed, for example, the open operation button 108 is touched as the operation content displayed in the button display area 102 subsequently. Then, after confirming the operation content, an opening operation for the valve 105 may be instructed and executed.

  However, the information related to the valve 105 displayed in the button display area 102 here is mainly limited to the basic operation state such as opening / closing or the contents of the operation mode for automatically performing these operations. Therefore, for additional additional information other than the screen display information of the plant equipment (valve 105), it is necessary to individually refer to the display contents on other display devices. In addition, the contents displayed in the equipment display area 101 are limited to typical plant equipment and piping lines so that the overall flow of the process in the system drawing can be understood. For this, detailed display screen information corresponding to an auxiliary device or the like created in another list format must be operated and displayed.

  In other words, the touch operation system applied to the current plant monitoring and control system has basically the same specifications as when operating an existing hard switch or display, and is conventionally displayed on the monitoring screen with the index finger. After selecting the operation target by touching the plant equipment to be instructed for operation, an operation mode button (for example, starting / stopping the pump 104 or the valve 105 for instructing the operation displayed on the same monitoring screen) The operation is instructed to operate by touching (open / closed etc.).

  As described above, the reason why the monitoring screen is displayed for operation in the same manner as existing hardware switches and displays can be roughly divided into two.

  The first reason is that many of the operators (operators) of plant monitoring and control systems at the time when the current touch operation system began to be introduced were familiar with analog equipment, so that the operation of known hardware equipment The application of a user interface that is significantly different from the base (operation switch, push button, etc.) is because it was considered that there is a possibility of hindering system operation (operation control) by monitoring related to plant equipment. Therefore, by adopting the same operation procedure as the operation base of known hardware devices, it is possible to flexibly cope with the transition period to an operator monitoring operation terminal having an operation display control function by digital processing without great difficulty. There is a background that it was possible.

  The second reason is due to the technical level related to the operation display control function of the operator monitoring operation terminal at the time of introduction of the touch operation. The touch operation at the time of introduction is mainly performed in a general industrial market in which the operation is performed only by a simple touch with one finger, and there is a background that there is no exception in the plant monitoring control system.

  In order to improve such a background, several techniques for improving the touch operation function have been proposed in the field related to the touch operation system for plant monitoring and control. Specifically, a “monitoring control device and an event detection recording medium used in this monitoring control device” that can realize various functions similar to those by a mouse operation by touch operations on the touch panel (see Patent Document 1). In the touch panel input system, when the operator moves the cursor by touching the touch panel, the “touch panel display device” that prevents the cursor from being hidden by the finger and disappearing (see Patent Document 2), reliability with improved operability For example, a “plant monitoring device” (see Patent Document 3) of a highly-functional digital instrumentation control system may be used.

JP 2003-58318 A Japanese Patent Laid-Open No. 9-237157 JP-A-9-149515

Since various operability related to touch operation that can be constructed with the operation display control function by digital processing of terminal devices that are mainstream in the general industrial field is hardly applied for plant monitoring control, There is an inconvenience (problem) that the operability by the touch operation is not excellent, and intuitive and efficient monitoring control cannot be performed.

  For example, in the existing plant monitoring control touch operation system, the density of screen display information displayed on one monitoring screen is set to be less than or equal to a specified level in a system diagram in which connections of pumps, pipes, tanks, etc. are displayed as plant equipment. In order to design the screen in this way, one system drawing may be displayed over a plurality of pages, or the detailed part of the screen display information may be displayed in a list format in another menu without displaying as a system drawing. is there. In such a case, when moving to another screen in page feed or list format, additional operations such as returning to the original screen again are required to confirm the relevant part, so operation by touch operation on the monitoring screen It is inconvenient because it is not excellent.

  Moreover, in the technique of Patent Document 1, in order to realize a function similar to a mouse operation, a double touch (multiple touch operation) function corresponding to a double click function in a mouse operation is provided as one of touch operations. In the technique of Patent Document 2, a touch panel is applied to a process operation console for performing an operation, and after touching the touch panel, the finger is touched so that it is not necessary to lift the finger from the touch panel to see the cursor hidden behind the finger. In the technology of Patent Document 3, a long press operation is performed by pressing a finger within a predetermined time within a predetermined range on the CRT screen where the plant operation is performed by touching the screen. If a part or display is hidden behind a finger or a finger touches multiple parts, It has to have a function to be much screen display.

  However, for any of the techniques according to Patent Documents 1 to 3, detailed information that is not normally displayed about symbols of plant equipment effective for performing operation control by specifically monitoring plant equipment, Alternatively, an operation display control function for displaying additional information related thereto is not established, and screen display information for one page of a system diagram that cannot be displayed on the monitoring screen is displayed, or a specific display As a result, the operation display control function effective for plant monitoring and control such as displaying the screen display information on another page by moving to another page for the screen display information of the plant equipment has not been sufficiently constructed. Inconvenience (problem) that operability by touch operation on the monitoring screen is not excellent and intuitive and efficient monitoring control cannot be performed. A.

  In short, in addition to the multi-touch operation, long-press operation, and slide operation described in each patent document at present, for example, a multi-touch operation that picks up and zooms in / out / rotates a target symbol is used for an operator monitoring operation terminal. As a touch operation, we will fully utilize the various operability related to touch operation built with the operation display control function by digital processing of recent terminal devices, and have excellent operability for touch operation effective for plant monitoring control The operation display control function is not established.

  The present invention has been made to solve such problems, and its technical problem is that it effectively applies the diversity of operation display control functions of recent terminal devices and is effective for plant monitoring control. An object of the present invention is to provide a touch operation system for plant monitoring and control that is excellent in operability and is capable of intuitive and efficient monitoring and control by touch operation on a monitoring screen by constructing an operation display control function.

  Hereinafter, a touch operation system for plant monitoring control according to the present invention will be described in detail with reference to the drawings.

  First, a technical outline of the touch operation system for plant monitoring control according to the present invention will be described. This touch operation system is a contact-type operation for a monitor screen of a display device attached to an operator monitoring operation terminal having an operation display control function by digital processing in a plant monitoring control system that performs operation control by monitoring plant equipment. Is for doing. As is well known, the operator monitoring operation terminal here is provided with a display device (monitor) having a display screen as a monitoring screen, as well as a CPU, main memory, auxiliary storage unit ( In addition to a storage device such as an HDD, an input / output device such as a keyboard / mouse is also provided. The operation unit has a display screen (monitoring) of the display device by an operation display control function of the CPU. A function for performing a contact operation (touch operation) on a screen is constructed.

  In general, in a plant monitoring control system, an operator performs a monitoring operation at an operator monitoring operation terminal, but the operator monitoring operation terminal has an image data acquisition means (image) for acquiring image data of a system drawing related to plant equipment. Scanner, digital camera, screen shot, CAD, etc.) and a control LAN are connected. Further, a controller is connected to the plant equipment via a process I / O device for inputting and outputting various signals for monitoring and operating the state of the plant equipment, and the controller controls the plant equipment. Further, a control LAN is connected to the controller, and bidirectional communication is possible with the operator monitoring operation terminal using the control LAN as a communication path.

  The characteristic function of the touch operation system constructed on the monitor screen of the display device in such an operator monitoring operation terminal is as a touch operation by the operator for the device display area on the monitor screen by the operation display control function. Multi-touch operation to pick up and push the target symbol of plant equipment displayed with multiple fingers, or to expand or contract, or torsionally rotate, and multiple touch operation to touch plant equipment target symbol multiple times with at least one finger And a long-pressing operation in which the target symbol of the plant equipment is pressed for at least one finger for a predetermined time and a sliding operation in which the target symbol of the plant equipment is slid while being touched with at least one finger. Is.

  However, in multi-touch operation, the detailed screen display information related to plant equipment in the equipment display area is normally hidden and displayed only when necessary so that it can be enlarged and reduced by pushing and shrinking. This corresponds to the function of rotating display by rotating the display and pushing and twisting, thereby realizing hierarchical display of screen display information. The multiple touch operation or long press operation corresponds to the function of displaying an additional information display button in the equipment display area in the vicinity of the symbol of the plant equipment in addition to the screen display information related to the plant equipment. Display is realized. However, it is preferable that the items included in the additional information display button can be variably set according to the plant operation mode related to the plant equipment, or can be customized and variably set by a user mainly an operator. The slide operation includes a function for displaying the additional information of the equipment symbol related to the additional information display button in the equipment display area by touching the additional information display button in the display development direction, and the outside of the plant equipment symbol in the equipment display area. A function to display the screen display information related to plant equipment by touching to the page (forward or backward of the page) and display on the equipment display area by touching the symbol of the plant equipment in the equipment display area This corresponds to the function of sliding the screen display information of the non-display portion for one page related to the system drawing of the plant equipment that is not cut.

  Hereinafter, the plant operation control touch operation system according to some embodiments will be described in detail.

  FIG. 1 shows a device display area 101 for a plant monitoring control display screen (monitoring screen) of a system diagram related to a plurality of plant devices in a plant monitoring control touch operation system to which a touch operation according to Embodiment 1 of the present invention is applied. In order to explain a state in which detailed screen display information that is not normally displayed is enlarged and switched as an enlarged display area E2 by a multi-touch operation on the symbol of the valve 105 which is a plant device in the normal display area E1 in FIG. It is the schematic which illustrated.

  Here, the system diagram itself relating to the plurality of plant devices on the monitoring screen has the same display contents as the device display area 101 shown in FIG. 3, and the buttons on the monitoring screen are the same as in the conventional touch operation system. It is assumed that the display area 102 is displayed at the same time. However, in the device display area 101, for example, the display position of the main piping line connecting the valve 105 and the tank 103b or the pump 104 (normal display area E1 including the symbol of the valve 105) is actually shown in the enlarged display area E2. In order to maintain appropriate display density on the monitor screen and the location of detailed screen display information that is not normally required, such as the drain pipe and drain valve 105b for the valve 105a, The portion of the display information is omitted as non-display from the display on the normal monitoring screen.

  Therefore, in the touch operation system according to the first embodiment of the present invention, the operation display control function is used to assume two fingers of the symbol of the valve 105 in the normal display area E1 as a touch operation (generally, a thumb and an index finger are assumed). However, other forms such as the use of the index finger and middle finger may be used, and detailed screen display information that is not normally displayed as shown in the enlarged display area E2 by performing a multi-touch operation by picking and spreading it. Is built in with other parts. According to the existing touch operation system, when displaying detailed screen display information that is not normally displayed as the enlarged display area E2, it is displayed in a list format in another menu or displayed on another screen. Therefore, when acquiring such detailed screen display information, additional operations such as returning to the original screen again and confirming related portions are necessary (for example, the name and device of the drain valve 105b to be operated). However, in this case, if a multi-touch operation is performed by picking up and pushing the symbol of the valve 105 in the normal display area E1 with two fingers, the drain for the valve 105a that is not normally displayed is displayed. Detailed screen display information showing the components of the piping and drain valve 105b is enlarged and displayed at a predetermined magnification including the other parts as an enlarged display area E2. Which is switching displayed.

  By the way, in multi-touch operation using the operation display control function, it can be picked up with two fingers and expanded to display it in a magnified view, or it can be reduced by pressing it with two fingers and shrunk, or it can be picked up with two fingers and twisted. You may make it respond | correspond to the function to change and display an angle (angle) by rotating. However, these are functions for an initial operation as a multi-touch operation. However, for example, when a finger is picked up with two fingers to expand and displayed in an enlarged size, and then enlarged with a two fingers and pressed down, an enlarged display area E2 is displayed. A display function for returning from the reduced display area to the normal display area E1 when the two fingers are pressed and shrunk and then expanded by pressing with two fingers. It is also possible to do. In addition, even when picking and rotating with two fingers, it is possible to have a function to rotate and display each angle by rotating clockwise or counterclockwise as if moving the actual object on the plane figure. It is. These various operation display control functions may be used together as necessary.

  In any case, the multi-touch operation according to the first embodiment basically has a function of displaying the enlarged display area E2 including the detailed screen display information related to the non-displayed plant equipment at a normal time when necessary. In the entire display of the system drawing including other main plant equipment such as 105, the valve 105 in the normal display area E1 is confirmed while checking the position in the entire system drawing without switching the equipment display area 101 itself of the monitoring screen. By performing a multi-touch operation on the symbol, the components of the drain piping and drain valve 105b, which are detailed screen display information that is normally hidden, are displayed as other enlarged display areas E2 on the device display area 101 of the monitoring screen when necessary. It is possible to perform switching display to enlarge the display together with the part.

  Therefore, according to the touch operation system having the operation display control function that enables the multi-touch operation according to the first embodiment, connection by piping such as the pump 104, the valve 105, and the tanks 103a and 103b, which are plant devices, is displayed. In the system drawing, in the normal state, the screen display information 101 is not displayed in the device display area 101 so that the entire system drawing can be easily grasped. For example, the normal display area E1 can be used when trouble or maintenance is necessary. A screen transition display that is intuitive and easy to understand on one monitoring screen is obtained by performing a multi-touch operation on the symbol of the valve 105 and enlarging and displaying a portion of detailed screen display information as shown in the enlarged display area E2. It becomes possible. As a result, the screen transition can be easily confirmed by an intuitive multi-touch operation, so that the screen display information is appropriately hierarchized to improve the monitoring operability, and the operation for the operator (operator) can be improved. The burden can be reduced.

  FIG. 2 shows a device display area 101 for a plant monitoring control display screen (monitoring screen) of a system diagram related to a plurality of plant devices in a plant monitoring control touch operation system to which the touch operation according to the second embodiment of the present invention is applied. It is the schematic illustrated in order to demonstrate a mode that the symbol of the valve 105 which is a plant apparatus in this is touch-operated or long-pressed several times, and the additional information display buttons 109a-109d are displayed in the vicinity of the symbol. ) Is a diagram related to the vicinity of the symbol of the valve 105 before the operation, and FIG. 5B is a diagram related to various additional information display buttons 109a to 109d in the vicinity of the symbol of the valve 105 after the operation.

  The existing touch operation system is designed to operate the valves and pumps represented by the symbols of the plant equipment such as valves and pumps. Only a single touch operation of the book was performed.

  On the other hand, in the second embodiment, as shown in FIG. 2A, for example, at least one finger (generally one thumb or index finger) is used for the symbol of the valve 105 of the plant equipment. Assuming that other forms such as middle finger, index finger, and middle finger may be used), perform a multiple touch operation by pressing twice (continuously touching twice), or at least one finger for a predetermined time As shown in FIG. 2B, additional information display buttons 109a to 109d for displaying various additional information as shown in FIG. 2 (b) are displayed on the plant equipment. By performing a slide operation that slides the finger in the direction in which the additional information display buttons 109a to 109d are deployed, for example, displayed around the symbol of a certain valve 105, for example, vertically and horizontally.

  Specifically, in FIG. 2B, the additional information display button 109a above the symbol of the valve 105 is for displaying an item of device design information, and the additional information display button 109a is displayed. When the slide operation is performed, specific device design information related to the valve 105 is displayed on the device display area 101 of the monitoring screen.

  Further, the additional information display button 109b on the left side of the symbol of the valve 105 is for displaying an inspection record item. If the additional information display button 109b is slid, the additional information display button 109b is displayed on the device display area 101 on the monitoring screen. Shows a specific inspection record relating to the valve 105.

  Further, the additional information display button 109c on the lower side of the symbol of the valve 105 is for displaying an item of operation history isolation information (abbreviated as isolation information), and the additional information display button 109c is slid. For example, specific isolation information related to the valve 105 is displayed on the device display area 101 of the monitoring screen.

  In addition, the additional information display button 109d on the right side of the symbol of the valve 105 is for displaying items of a maintenance drawing (abbreviated as maintenance drawing), and if the additional information display button 109d is slid, A specific maintenance drawing relating to the valve 105 is displayed on the device display area 101 of the monitoring screen.

  As the type operation procedure as the touch operation, for example, by pressing the symbol of the valve 105 shown in FIG. 2A twice or long-pressing, the device design information and inspection as shown in FIG. Various additional information display buttons 109a to 109d linked to the recording, isolation information, and maintenance drawings are displayed on the top, bottom, left and right of the symbol of the valve 105, and thereafter, the desired information on the additional information display buttons 109a to 109d If a displayed item is selected and a finger is slid in the developing direction, specific additional information (illustrated) can be displayed in the device display area 101 of the monitoring screen.

  Here, regarding the items held in the additional information display buttons 109a to 109d displayed on the top, bottom, left, and right of the symbol of the valve 105, the plant operation mode (start / stop, normal) is selected according to the type of plant equipment by the operation display control function. If the variable display setting is made so that the menu is frequently used according to driving, periodic inspection, etc.), it can be expected to further improve convenience. For example, during normal operation, four types of buttons are displayed: operation history, equipment design information, links to related parameter screens, and related parameter history display, and equipment design information, inspection records, isolation information, maintenance drawings during periodic plant inspections The case where four types of buttons of the link to the symbol are displayed on the top, bottom, left, and right of the symbol after long-pressing the symbol of the plant equipment can be illustrated.

  Further, the items included in the additional information display buttons 109a to 109d can be arbitrarily set by the user by the operation display control function, and can be customized and variably set according to the preference of the operator (operator). It is preferable to have it.

As a result, more additional information (especially maintenance information for plant operation) than the existing touch operation system can be displayed intuitively, especially when long-pressing a plant equipment symbol. If the item of the information display button is variably set according to the plant operation mode, it is preferable because the additional information required by the operator (operator) can be displayed appropriately and in a timely manner.

  In the existing touch operation system, the page change (page advance and retreat) for the display of the screen display information related to the symbol of the plant equipment is performed by the dedicated button in the button display area. In the third embodiment, the operation display control is performed. A function for changing pages by sliding a finger after touching one place other than a symbol of a predetermined plant device (for example, valve 105) in the device display area 101 of the monitoring screen by the function is constructed. Specifically, at least one finger other than the plant equipment symbol (in this case, it is assumed that one thumb or index finger is used for general purposes, but the middle finger, index finger and middle finger are used, etc.) It is also possible to move the page forward by sliding the finger to the left after touching it in the other form), and to move the page backward by sliding the finger to the right. Operation becomes possible.

  In addition, the display related to the screen display information of the system drawings including various plant devices may have screen display information of a non-display portion for one page that is not displayed in the device display area 101 of the monitoring screen. In such a case, a plant device that is not completely displayed on the device display area 101 of the monitoring screen by the slide operation to the symbol of the plant device (for example, the valve 105) in the device display area 101 of the monitoring screen by the operation display control function. It is effective to have a function of slidingly displaying the screen display information of the non-display portion for one page related to the system diagram of (valve 105). For example, assuming that there is about half of the non-display portion for one page related to the system drawing that cannot be displayed on the right side on the device display area 101 of the monitoring screen in FIG.
