Description

  The present invention relates to a monitoring panel display device and a monitoring panel display method for displaying a monitoring panel for monitoring the state of facilities and equipment groups, and more specifically, an image that allows a computer to handle a monitoring panel that is easy to see and has excellent visibility. The present invention relates to a monitoring panel display device and a monitoring panel display method.

  Conventionally, as a monitoring panel for monitoring the status of facilities and equipment groups such as power systems and plants, many mosaic blocks with illuminants and figures and characters that schematically represent the structure of the facilities and equipment groups are drawn. Mosaic type monitoring boards are used that are arranged in a grid (see, for example, Patent Document 1 and Patent Document 2). In the mosaic type monitoring board, the joints between the mosaic blocks arranged in a grid are visually recognized as lines, and a natural grid pattern is formed. It becomes the reference of the viewpoint when visually recognizing a figure representing the facility or equipment group, and has the advantage of good visibility. However, the mosaic monitoring panel displays a wide range of facilities and equipment groups such as power systems and plants using a number of physically substantial mosaic blocks. Wiring and the like for lighting the body is required, and there is a drawback that it takes cost and time to create and maintain.

On the other hand, in order to solve the above-mentioned drawbacks of the mosaic type monitoring panel, a single line diagram created using a computer is displayed on a display device in which one or more large video projectors or liquid crystal panels are arranged, It has also been proposed to use a monitoring panel (see, for example, Patent Document 3). However, the monitoring panel displayed by this large video projector or liquid crystal panel simply displays the arrangement status and connection relationship of facilities and equipment groups as a planar two-dimensional image consisting of figures and lines connecting them. Therefore, there is a lack of realism as a monitoring board, and there is no lattice-like ground pattern that was in the mosaic type monitoring board, so there is a disadvantage that visibility is poor.

It solves the above problems.

  Further, the present invention is a monitoring panel display method for displaying a monitoring panel for monitoring the state of a facility or a group of facilities as an image, and the displayed monitoring panel image schematically shows the configuration of the facility or the group of facilities. An image and a display image representing the state of a facility or equipment group that changes based on an external telemeter signal, and (a) reads out subdivided background images constituting the background image stored in the background image storage means (B) a step of generating a background three-dimensional model corresponding to the read subdivision background image and (c) the steps (a) to (b) are all subdivision background images constituting one background image. (D) a step of reading a display image to be displayed based on an external telemeter signal from a display image storage means for storing the display image, and (e) a read table.

A step of arranging at a predetermined position on the front side of the surface, a step of texture mapping the subdivided background image to be displayed on the background surface of the background 3D model, and a surface serving as a display device of the display 3D model. The specified display part from the step of texture mapping the display image to be displayed and the background 3D model and display 3D model placed in the 3D space A monitoring board display method comprising: a rendering step including a step of obtaining a corresponding two-dimensional image; and (i) a step of storing or displaying the obtained two-dimensional image. Is a solution.

  In the monitoring panel display device and the display method of the present invention, the display device image includes a figure, a number, a symbol, a code, a character, or a combination of two or more of these indicating the type, state, and / or name of the facility or equipment. This is an image to which colors are given as necessary. These images may be created each time, but are preferably stored in the display image storage means for storing the display image, and appropriately from the display image storage means based on an external telemeter signal. Read out. An image such as a predetermined character can be superimposed on the display image when reading from the display image storage means. In addition, it is optional to appropriately enlarge or reduce the read display image.

  The read display image is texture-mapped to a display three-dimensional model corresponding to the display image. The display three-dimensional model corresponding to the display image is a three-dimensional model having a surface for texture mapping of the display image, and such a three-dimensional model may be generated each time. However, it may be generated by storing it in the storage means in advance and reading it as needed. The surface on which the display image is texture-mapped is usually a plane having the same or similar shape as the shape of the display image, although it depends on the type of the display. Such readout of the display device image and texture mapping to the display device three-dimensional model are performed for all of the display device images to be displayed.

  On the other hand, in the monitoring panel display device and the display method of the present invention, the background image schematically showing the configuration of the facility or the equipment group is stored in the background image storage means as one or a plurality of subdivided background images. Images are sequentially read out from the background image storage means and texture-mapped on the background surface of the corresponding background three-dimensional model. The background three-dimensional model corresponding to the subdivision background image is a three-dimensional model having a surface for texture mapping of the subdivision background image, and such a three-dimensional model may be generated each time. Alternatively, it may be generated by storing in advance in the storage means and reading out as needed. The surface on which the subdivision background image is texture-mapped is usually a plane having the same or similar shape as the subdivision background image. Such texture mapping of the subdivided background image to the background three-dimensional model is performed for all subdivided background images constituting one background image, and thus is assumed in advance by the subdivided background image subjected to texture mapping. One background image, that is, a monitoring board image is formed. If one background image is composed of one subdivided background image, it is a matter of course that the subdivided background image is read out and its texture mapping only needs to be performed once.

  The background 3D model and the display 3D model are arranged in a virtual 3D space in the computer. First, the background three-dimensional model is arranged at a position corresponding to the position in the background image of the subdivided background image corresponding to the background three-dimensional model. At this time, it goes without saying that the background three-dimensional model is arranged such that the surfaces on which the subdivision background image is texture-mapped are oriented in the same direction and form one surface continuously. The position of the subdivision background image in the background image can be known, for example, by including position information in the file name of the subdivision background image. Note that the texture mapping of the subdivision background image to the background 3D model may be performed before the background 3D model is placed in the 3D space, or after the background 3D model is placed in the 3D space. Moreover, it may be performed after a two-dimensional image of the background three-dimensional model is obtained by projection conversion. In any case, one or a plurality of background three-dimensional models arranged in the three-dimensional space constitutes a surface to be one background image in the three-dimensional space by the surface to be texture-mapped.

  Next, the display 3D model is placed at a predetermined position in the same 3D space as the background 3D model. The predetermined position is a position where a display image corresponding to the three-dimensional model of the display is to be arranged in a background image schematically representing a facility or equipment group. The information about this position is obtained by, for example, determining the correspondence between the position of data in the external telemeter signal corresponding to the display image and the position where the display image is to be displayed in advance. Can be obtained at the time when the display device image to be displayed is read out. Note that the 3D model of the display unit is such that the surface on which the display unit image is texture-mapped is directed to the same side as the surface on which the subdivision background image is texture-mapped in the background 3D model. The background image is arranged in front of the surface on which texture mapping is performed. The texture mapping of the display image to the display 3D model may be performed before placing the display 3D model in the 3D space, or after placing the display 3D model in the 3D space. Further, it may be performed after a two-dimensional image of the display three-dimensional model is obtained by projection conversion. By performing the arrangement of the display 3D model in the 3D space for all the display images to be displayed, a surface on which the display image is texture-mapped is provided at a predetermined position in the 3D space. Display 3D model can be arranged.

  In the monitoring panel display device and the monitoring panel display method of the present invention, a rendering means or a rendering step is provided, in addition to the arrangement of the background three-dimensional model and the display unit three-dimensional model in the three-dimensional space described above, For the background 3D model and the display 3D model placed in the 3D space, set the viewpoint so that the display 3D model is in front of the background 3D model. The two-dimensional image to be displayed can be obtained by arranging and converting to a two-dimensional coordinate system, and further performing texture mapping of the subdivision background image and the display image. Although it depends on the size of the two-dimensional image to be displayed, the size of the view screen that is the projection surface during rendering is usually smaller than the size of the entire surface that is a single background image formed in the three-dimensional space. By moving the viewpoint position in parallel with the surface to be the background image, the portion to be rendered, that is, the position in the background image of the two-dimensional image to be displayed can be selected. In addition, by moving the viewpoint position in the direction perpendicular to the background image, the two-dimensional image obtained by rendering can be enlarged or reduced.

  In the monitoring panel display device and the monitoring panel display method of the present invention, a plurality of sets of subdivided background images having different drawing magnifications are stored in the background image storage means, and the background is selected according to an enlargement or reduction instruction from the outside. By providing means or step for selecting a set of subdivided background images to be read from the image storage means, it is possible to change the display magnification of the displayed monitor panel. In accordance with the drawing magnification of the selected subdivision background image, the size of the display device image and the display device three-dimensional model corresponding to the display device image are also changed. At this time, with respect to the display image, a plurality of sets of display images having different drawing magnifications may be stored in the display device image storage means in correspondence with sets of subdivided background images having different drawing magnifications. The display device image may be used after being appropriately enlarged or reduced.

  The monitoring panel display device and the monitoring panel display method of the present invention include means or steps for changing the color of the display device image designated by the telemeter signal at a predetermined period based on the telemeter signal from the outside. Is desirable. For example, for a specific display image, the display image can be displayed in flicker by alternately switching the color between “red” indicating lighting and “white” indicating extinction at a predetermined cycle. .

  In the monitoring panel display device and the monitoring panel display method of the present invention, at least for the display image, the generation of the display 3D model corresponding to the reading of the display image to be displayed, and the 3D of the display 3D model By providing means or steps to repeat rendering including placement in space and texture mapping every predetermined time, the image of the display whose state may change sequentially is updated at predetermined time intervals. As a result, the state of the facility or equipment group to be monitored can be displayed in real time.

  In the monitoring panel display device and the monitoring panel display method of the present invention, the telemeter signal from the outside is usually an actual telemeter signal indicating the state of the facility or equipment group to be monitored. It may be a simulated telemeter signal. In this case, the monitoring board display device of the present invention can be used as a monitoring board display device for training, and the monitoring board for training can be displayed by the monitoring board display method of the present invention.

  The monitoring panel display device and the monitoring panel display method of the present invention can be realized by a computer having an appropriate storage device, arithmetic processing device, and input / output device, and a program for causing the computer to perform a predetermined operation. The program which recorded the procedure which performs the monitoring board display method of this invention is also the object of this invention. The program of the present invention may be recorded on an appropriate recording medium, may be present in a storage device of a computer, or may be prepared to be transmitted via communication means. good.

  There is no particular limitation on the monitoring panel targeted by the present invention, not only the power system monitoring panel that monitors the state of the power system, but also the monitoring panel that monitors the operation state of the plant, and the monitoring status that shows the operation status of trains, trains, etc. The present invention is intended for all types of monitoring boards that monitor the state of facilities or equipment groups. The monitoring board image obtained by the present invention can be displayed as a monitoring board image on a normal display device attached to a computer such as a liquid crystal display device or a CRT display device. Not to mention projectors, large liquid crystal display devices and plasma display devices, it is also possible to display on a multi-screen display device in which a plurality of them are arranged in a row or matrix, It is also possible to display on a normal display device attached to the computer as a monitor image displaying the configuration and state of the facility or equipment group to be monitored.

  According to the monitoring panel display device and the monitoring panel display method of the present invention, various displays are displayed as images on a background image schematically representing facilities and equipment groups using a three-dimensional computer graphics technique. Therefore, it is possible to display not only background images but also display images that change sequentially as images with a three-dimensional effect that mimics a mosaic-type monitoring panel that is usually familiar to observers. An excellent advantage is obtained in that a monitoring panel having almost the same visibility and visibility as the monitoring panel can be provided. Moreover, since the monitoring board image obtained by the present invention is a computer image, it is easy to maintain, does not require a large number of mosaic blocks and light emitters, and can be used to change the configuration of facilities and equipment groups to be monitored. By changing the background image or the display device image, or by changing the table designating the type and display position of the display device image read out by an external telemeter signal, there is an advantage that it is possible to respond quickly. In particular, prepare multiple types of tables that specify the background image, display image, and the type and display position of the display image read by the telemeter signal from the outside according to the type of facility and equipment group to be monitored. In this case, it is very convenient because the facilities and equipment groups displayed on the monitoring panel can be changed at any time by appropriately selecting and using them. This advantage is particularly useful in a monitoring panel display device that may change various facilities and equipment groups to be displayed, such as a training monitoring panel display device.

  Such a monitoring panel display device and a monitoring panel display method of the present invention can be realized by an ordinary computer and a program of the present invention describing a procedure for causing the computer to execute the monitoring panel display method of the present invention. Can be constructed very simply. The program of the present invention can be constructed using a commercially available application program interface (API) for computer graphics, and can flexibly respond to changes and edits on the user side according to individual monitoring panels. It has the advantage that.

  Hereinafter, the present invention will be described with reference to the drawings regarding a power system monitoring panel that is the most typical monitoring panel, but the present invention is not limited to the display device and the display method of the power system monitoring panel illustrated. Of course.

  FIG. 1 is a block diagram showing an outline of a monitoring panel display device according to the present invention, wherein 1 is a monitoring panel display computer, 2 is a CPU of the monitoring panel display computer 1, and 3 is a storage device. The storage device 3 includes a background image storage unit 4, a display unit image storage unit 5, a design table 6 storing a display design, and a layout table 7 storing a display layout. The background image storage unit 4, the display device image storage unit 5, the design table 6, and the layout table 7 may all be a partial storage area in the storage device 3, or any one or Two or more may be separately independent storage devices, or may be storage devices in remote locations that are appropriately connected to the monitor panel display computer 1 via a network or communication means. The storage device 3 also stores the program of the present invention describing the procedure for causing the monitoring panel display computer 1 to execute the monitoring panel display method of the present invention. As the monitoring panel display computer 1, an appropriate computer such as a normal personal computer can be used.

  Reference numeral 8 denotes a graphic processor unit (GPU). The GPU 8 includes an appropriate geometric engine and rendering engine (not shown). Reference numeral 9 is a video memory, and 10 is a display device. The display device 10 is not particularly limited as long as the monitor panel image can be displayed, and an appropriate display device such as a liquid crystal display device, a plasma display device, a video projector, or a CRT display device can be used. Reference numeral 11 denotes a bus, and the CPU 2, the storage device 3, and the GPU 8 are connected to each other via the bus 11. Reference numeral 12 denotes a monitoring panel controller, which processes various measurement signal data transmitted from remote monitoring devices 13a, 13b, 13c,... Is supplied to the bus of the computer 1. As will be described later, when the monitoring panel display device of the present invention is used as a training monitoring panel display device, various measurement signal data transmitted from the remote monitoring devices 13a, 13b, 13c,. Instead, simulated measurement signal data transmitted from the training computer is input to the monitoring panel controller 12. Alternatively, measurement signal data already processed into a predetermined format by the training computer may be supplied to the bus 11 via the monitoring panel controller 12 or not.

  FIG. 2 is a diagram illustrating an example of a background image stored in the background image storage unit 4. The background image 14 corresponds to the whole of a single monitoring panel, and mainly a semi-fixed configuration that does not change in a short period, such as the type and arrangement of facilities and equipment groups, and the mutual connection relationship, is schematically illustrated by a figure or the like. It is shown. The background image 14 is positioned as a background of a display device image to be described later in the monitoring panel image displayed by the present invention. Although the background image 14 mainly schematically shows a semi-fixed configuration by a figure or the like, the figure corresponding to the background image also corresponds to a portion that must be changed in a short time based on a telemeter signal or the like. It's okay to draw etc.

  In the case of the example shown in FIG. 2, the background image 14 is composed of 12 × 6 = 72 subdivided background images 15 having 12 columns A to L in the horizontal direction and 6 rows in the vertical direction 1 to 6. Each of the subdivided background images 15, 15, 15... Is given a name such as A 1 or B 2 corresponding to the position occupied in the background image 14. It is possible to know at which position in the background image 14 it should be arranged. For example, the subdivided background image 15 indicated by F3 in FIG. 2 occupies the position of F columns and 3 rows in the background image 14 as indicated by the broken line in the figure, and is displayed as, for example, “subdivided background image F3”. can do.

  Since the subdivided background images 15, 15, 15... Constituting the background image 14 can be drawn using a normal graphic tool, they can be easily edited or changed. There is an advantage of being able to respond quickly to changes. Further, since the subdivided background images 15, 15, 15... Are stored in the background image storage unit 4 as individual files for each subdivided background image 15, the file name of each subdivided background image 15 is described above. By attaching a combination of alphabets and numbers representing the columns and rows, it is possible to easily know the position that should be occupied in the background image 14 when reading the file. Alternatively, the subdivided background image 15 at a specific position in the background image 14 can be read by specifying a file name. Of course, the number of subdivided background images 15 constituting the background image 14 varies depending on the size of the monitoring board to be displayed and the size of the subdivided background image, and is more than 72 shown in FIG. The background image 14 may be composed of a single subdivided background image 15 in an extreme case.

  FIG. 3 is an enlarged view of an example of the subdivided background image 15 and corresponds to the subdivided background image at the position F3 in FIG. In FIG. 3, 16 and 16 are equipment name displays, which are not scheduled to be changed in the short term, and the equipment itself is not monitored, so it is drawn as a semi-fixed background image. Yes. Reference numerals 17, 17, and 17 denote power transmission lines that connect the respective facilities. Since the state is not a monitoring target, it is drawn as a semi-fixed background image. Reference numeral 18 denotes a line switch, and 19a, 19b, and 19c circuit breakers. These are also figures corresponding to a display that needs to be changed and displayed based on a telemeter signal, but it is easy to see the entire subdivided background image 15. In order to do this, it is drawn for convenience. Since the line switch 18 and the circuit breakers 19a, 19b, 19c drawn on the subdivided background image 15 are three-dimensionally superimposed on the display image that changes based on the telemeter signal, as will be described later. Even if the line switch 18 and the circuit breakers 19a, 19b, and 19c are drawn on the subdivided background image 15, there is no problem.

  Reference numeral 20 denotes an electric station name display. The electric place name display 20 is a portion corresponding to a place name display for displaying the name of a facility or equipment whose color or the like must be changed based on a telemeter signal. In the subdivision background image 15 shown in FIG. Is white and plain. Reference numeral 21 denotes a portion corresponding to a numerical display that displays a numerical value that changes such as a voltage based on a telemeter signal, and a figure imitating the shape of the numerical display is drawn.

  The above-mentioned figures of the power transmission line 17, the line switch 18, the circuit breakers 19a, 19b, 19c, the name display 20 and the numerical display 21 are all imitating the figures representing them in the mosaic type monitoring panel. And, it does not give a sense of incongruity to the observer who is familiar with the conventional mosaic type monitoring board. Furthermore, in the subdivision background image 15, a graphic 22 simulating a lattice pattern formed by the joint portion of the mosaic block in the mosaic type monitoring board is drawn. The presence of this grid pattern as a ground pattern in the background of the monitoring panel image can give the viewer a reference point of view, so that it is easier to see and see than when the monitoring panel is drawn on a completely plain background. There is an advantage that the performance is improved.

  Returning to FIG. 1, a procedure for forming a background image of the monitoring board by the monitoring board display device of the present invention will be described first. When the CPU 2 receives a background image creation command via an input / output device (not shown) or according to the activated program of the present invention, the CPU 2 subdivides the background image 15A1, 15B1, 15C1,. Are sequentially read out and sent to the GPU 8. The GPU 8 recognizes the position of the subdivided background image in the background image 14 from the order of the subdivided background images 15A1, 15B1, 15C1... Or the combination of alphabets and numbers assigned to the file names. . The GPU 8 further creates a background three-dimensional model corresponding to the sent subdivided background images 15A1, 15B1, 15C1,..., And performs coordinate conversion based on the position of the corresponding subdivided background image in the background image 14. And place it in a virtual three-dimensional space. The background three-dimensional model may be generated whenever necessary, or may be generated by reading out a background three-dimensional model stored in advance from the storage device.

  The 3D shape of the background 3D model is not particularly limited as long as a surface for texture mapping of the subdivision background image is provided, but in order to avoid unnecessary complexity, the 2D shape of the subdivision background image is changed to A cubic or rectangular parallelepiped three-dimensional model having a combined surface is preferable, and one surface of the cube or rectangular parallelepiped is preferably a surface on which the subdivision background image is texture-mapped. In addition, although there is no particular limitation on the expression method of the background three-dimensional model, the expression by a triangle or a quadrilateral polygon is preferable from the viewpoint of ease of generation of the three-dimensional model.

  The background 3D model is placed in the 3D space in such a way that the subdivision background images in each background 3D model are all texture-mapped so that all the texture-mapped images are oriented in the same direction. It goes without saying that they are arranged so as to constitute one background image as a whole. Note that the texture mapping of the individual subdivided background images 15A1, 15B1, 15C1,... To the corresponding background three-dimensional model may be performed before the background three-dimensional model is arranged at a predetermined position in the three-dimensional space. It may be performed after the arrangement, or may be performed after the conversion to the two-dimensional image is completed after setting the viewpoint described later.

  FIG. 4 is a diagram showing an example of a graphic display image stored in the display image storage means 5. The display device image is defined as an image on a background image having a grid-like ground pattern as in the subdivision background image. As shown in FIG. 4, symbols such as “TYPE 1”, “TYPE 2”,... For example, “TYPE 1” is the circuit breaker 19, “TYPE 2” is the line switch 18, “TYPE 3” is the ground, “TYPE 4” to “TYPE 7” is the electric bus, and “TYPE n” is the large name display. “TYPEm” is a graphic representing a small place name display, and in the example of FIG. 4, four types of graphics are displayed for each type (in FIG. 4, the difference in color is “white”, “black”). , “Fine hatching” and “coarse hatching”) are defined as images and stored in the display image storage means 5. Reading of the display image from the display image storage means 5 is performed by cutting out only the portion corresponding to the corresponding display image, as indicated by the arrow in the figure.

  FIG. 5 is a diagram showing an example of a display image of numbers and signs stored in the display image storage means 5. As shown in FIG. 5, a plurality of sets (C1 to C7) are defined and stored as numbers 0 to 9, plus or minus signs, up or down arrows, left or right arrows, and decimal points. However, for example, the set of C1 is “green”, the set of C2 is “red”, and the set of C3 is “yellow”. C0 is a set of blank graphics, and when no numbers or symbols are displayed, this C0 blank graphic set is used. In FIG. 5, the character “E” shown in the row E represents “error”, and each character displayed as “EEEEEEEE” is “E” having a different color. In the leftmost column of the “EEEEEEEE” column, a blank figure without the “E” character is defined. This is used when no error display is performed. Similarly to the reading of the display image shown in FIG. 4, the reading of the display image of numbers and signs is performed only for the portion “1” if the number is “1”, and “+” if the number is “+”. This is done by cutting out only the part of “”. The images of figures, numbers, characters, codes, etc. shown in FIGS. 4 and 5 are merely examples, and figures, numbers, characters, signs, symbols, etc. other than those shown in FIGS. 4 and 5 are defined as figures. Needless to say, it may be stored in the display device image storage means 5.

  In the present invention, reading of the display device image from the display device image storage means 5 based on the telemeter signal from the outside is performed as follows, for example. That is, as shown in FIG. 1, various measurement signal data transmitted from the remote monitoring devices 13a, 13b, 13c... Existing in the remote place are arranged in a predetermined format by the monitoring panel controller 12. A series of telemeter signal data is supplied to the bus of the monitor panel display computer 1. On the other hand, the monitor panel display computer 1 is provided with a layout table 7. The layout table 7 defines the correspondence between the position of data in the transmitted telemeter signal and the display to be displayed. It has been. For example, the data from the first bit to the second bit of the data portion of the telemeter signal data is data indicating the state of the circuit breaker of TYPE1, and the circuit breaker should be displayed at any position in the background image 14. Whether there is any is described in the layout table 7. Further, the design table 6 describes, for example, in which location in the display image storage means 5 the four types of display images having different colors of TYPE 1 are stored.

  Therefore, when the CPU 2 receives the telemeter signal, it recognizes that the data from the first bit to the second bit of the data part in the telemeter signal is data about the circuit breaker of TYPE 1 based on the layout table 7. Information about the type of the display to be displayed, information about the colors included in the data from the first bit to the second bit, and display of the display image of TYPE 1 described in the design table 6 The display image of the circuit breaker of the specified color of TYPE 1 is read from the display image storage means 5 based on the information about the storage location in the display device storage means 5 and specified in the display image and the layout table 7 The information on the position to be displayed in the background image 14 that is displayed is associated with G It is possible to convey to the U8.

  Similarly, the CPU 2 recognizes that the data from the 3rd bit to the 4th bit of the data portion in the telemeter signal is the data for the line switch of TYPE2, and about the type of the display to be displayed. Information about the colors included in the data from the 3rd bit to the 4th bit, and the storage location in the display storage means 5 of the display image of TYPE 2 described in the design table 6 Based on the information, the display image of the line switch of the specified color of TYPE 2 is read from the display image storage means 5, and the display image and the display in the background image 14 specified in the layout table 7 are displayed. The information about the position to be associated is transmitted to the GPU 8 in association with the information. In the display image of the circuit breaker or the line switch, the color, that is, the color is a symbol representing the state. For example, if it is “green”, it is in the “cut” state, if it is “red”, it is in the “entered” state, and the correspondence between these can be determined in advance.

  In addition to the relationship between the position of the data in the telemeter signal and the type of display image to be displayed, the layout table 7 can include information about the characters to be displayed in that type of display image. For example, the data from the 5th bit to the 6th bit of the data portion in the telemeter signal is data on a name display image that displays the name of the electric station of TYPEn. In the name display image, A designation to represent the characters “Hamamatsu” can be determined in the layout table 7. This designation can also include information about the font and size of the character to be displayed, its position in the name display image, and the like.

  Therefore, based on the layout table 7, the CPU 2 recognizes that the data from the 5th bit to the 6th bit of the data portion in the telemeter signal is the data for the name display of TYPEn, and this should be displayed. Information about the display type, information about the colors included in the data from the 5th bit to the 6th bit, and the display storage of the name display image of TYPEn described in the design table 6 Based on the information about the storage location in the means 5, the image of the place name indicator of the specified color of TYPEn is read from the display image storage means 5, and should be expressed in the layout table 7. Based on the information about the character, the specified character is superimposed on the read name indicator image, and the character is superimposed. As an indicator image images, in association with information about the position to be displayed in the background image 14 that is specified in the layout table 7, and to convey the GPU 8.

  This is basically the same even if the display image is a numerical display. However, regarding the numerical display, the type of display image is determined according to the number of digits of the numerical value to be displayed, the up / down / left / right arrow symbols, and the necessity of displaying a sign such as plus / minus. Regarding the numerical display, the layout table 7 includes information on the correspondence between the position of the data in the telemeter signal and the type of the numerical display to be displayed, and the position of the numerical display in the background image. In addition, information such as the correspondence between the state of the bit at the specified position and the color such as the number to be displayed, and the correspondence between the state of the bit at the specified position and the position of the decimal point to be displayed is included. be able to.

  Therefore, when the CPU 2 receives the telemeter signal, based on the layout table 7, the data from the 11th bit to the 26th bit of the data portion in the telemeter signal, for example, displays three digits in the up and down arrows. Information about the type of numerical display to be displayed, information about the type of numerical display to be displayed, numbers to be displayed included in the data from the 11th bit to the 26th bit, etc. Information about colors, information about codes to be displayed, information about numerical values to be displayed, information about positions of decimal points to be displayed, and display of images such as numbers described in the design table 6 Based on the information about the storage location in the storage device 5, the upward or downward of the designated color from the display device image storage device 5 The image of the designated arrow is read out, then the designated number image of the designated color is sequentially read out for three digits, and the arrow and the three number image are designated in the layout table 7 as a set of display images. The information about the position to be displayed in the background image 14 that is displayed is associated with the information to the GPU 8.

  The GPU 8 creates a display 3D model corresponding to the sequentially displayed display images, performs coordinate conversion based on the position of the corresponding display image in the background image 14, and generates a virtual 3D Place in space. Generation of such a display three-dimensional model and arrangement in a three-dimensional space are performed for all displays to be displayed. The display three-dimensional model may be generated whenever necessary, or may be generated by reading a display three-dimensional model stored in advance from the storage device.

  As with the background 3D model, the 3D shape of the display 3D model is not particularly limited as long as a surface for texture mapping of the display image is provided, but in order to avoid unnecessary complexity It is preferable to use a cube or rectangular parallelepiped three-dimensional model with a surface that matches the two-dimensional shape of the display image, and one surface of the cube or rectangular parallelepiped is used as a surface for texture mapping of the display image. preferable. In addition, although there is no particular limitation on the representation method of the display three-dimensional model, in terms of the ease of generation of the three-dimensional model, the representation by a triangular or quadrangular polygon is preferable like the background three-dimensional model. As for the display image of the numerical display, one display three-dimensional model is generated for each read code and number, and a predetermined number of the display three-dimensional models are arranged to form one numerical value. It is good also as a display 3D model corresponding to a display, and you may make it produce | generate one display 3D model with respect to one numerical display comprised by several code | symbol or a numerical image.

  The arrangement of the display 3D model in the 3D space is such that the surface on which the display image in each display 3D model is texture mapped is the surface on which the background image in the background 3D model is texture mapped. It is done so as to face the same direction. The texture mapping of the display image to the corresponding display 3D model may be performed before or after the display 3D model is arranged at a predetermined position in the 3D space. However, after the viewpoint to be described later is set, the conversion to the two-dimensional image may be performed.

  As described above, when the background three-dimensional model and the display unit three-dimensional model are arranged in the three-dimensional space, the GPU 8 sets the viewpoint in the three-dimensional space, and the light source according to a normal rendering method. Set up. FIG. 6 schematically shows the relationship between the background three-dimensional model 23 arranged in the three-dimensional space, the display unit three-dimensional model 24, and the viewpoint 25 in a simplified manner. Although the background three-dimensional model 23 is represented as a single thin rectangular parallelepiped in FIG. 6, it is actually composed of a large number of background three-dimensional models. One background image, that is, one monitoring board image is formed on the entire surface. The display 3D model 24 is disposed on the near side of the background 3D model with the texture-mapped surface facing the viewpoint 25 side. In FIG. 6, the display three-dimensional models 24, 24, 24 are expressed as thin rectangular parallelepipeds, but it goes without saying that the display three-dimensional model is not limited to the illustrated shape.

  A viewpoint 25 is set in such a three-dimensional space. As shown in the figure, the viewpoint 25 is set at a position where the display 3D model is in front of the background 3D model, and the light source (not shown) is texture-mapped to the background 3D model and the display 3D model. The position is set so that the surface is evenly illuminated. A region surrounded by an alternate long and short dash line extending from the viewpoint 25 is a view volume, and a background three-dimensional model and a display three-dimensional model located in the view volume are projected on a view screen 26 set at an appropriate position. Then, a hidden surface process is performed and converted into a two-dimensional image. The region converted into the two-dimensional image is a region indicated by A surrounded by a solid line on the background three-dimensional model 23. After the conversion into the two-dimensional image, the background image and the display device image are texture-mapped to the background three-dimensional model and the display device three-dimensional model, respectively, thereby obtaining a monitoring board image to be displayed. The GPU 8 can appropriately store the monitor board image created in this way in the video memory 9 and display it on the display device 10. The texture mapping can be performed at an appropriate timing, and may be performed before the background 3D model and the display 3D model are arranged in the 3D space. It may be done before conversion.

  FIG. 7 shows an example of the monitoring board image created as described above, with only a portion corresponding to one subdivision background image shown in FIG. 3 taken out. As shown in FIG. 7, the electric station name display 20, which was blank in FIG. 3, contains “Hamamatsu” and its ground color is “white”. The display image of the electric name display 20 is, for example, a “white” name display image at the top of the name display image of the type shown as TYPEn in FIG. When reading the place name display image, the CPU 2 superimposes the characters “Hamamatsu” based on the designation of the layout table 7 and sends them to the GPU 8.

  On the other hand, the line switch 18 and the circuit breaker 19a are displayed in “red” (“black” in the drawing). For example, the line switch 18 is in the “on” state and the circuit breaker 19a is in the “on” state. It is shown that. The circuit breakers 19b and 19c are displayed in “green” (“white” in the figure), which indicates that, for example, the circuit breakers 19b and 19c are in the “cut” state. A numerical value “777” is also displayed on the numerical display 21, which indicates that the voltage value represented by the symbol V is “777 kilovolts”, for example.

  FIG. 8 shows another example of the monitoring board image extracted only for a portion corresponding to one subdivided background image. As shown in FIG. 8, the electric station name indicator 20 is obtained by superimposing the characters “Shizuoka” on the uppermost image of the name indicator image of TYPEm shown in FIG. The displayed downward arrow and the number “0” are based on the telemeter signal, the image of the downward arrow specified by the display image shown in FIG. 5 and the number “0” of the specified color. It is an image obtained by reading out an image and texture-mapping it to the corresponding three-dimensional display model. If the numerical indicator 21 is a type that displays an arrow pointing in either up or down direction and three digits, a blank is placed between the downward arrow and the numeral “0” in the numerical indicator 21. That is, there are two display device images to be shown. This numerical display displays the passing electric power in the direction of the arrow as a numerical display. Reference numerals 27a to 27d denote electric power buses to be monitored, which are images obtained by texture mapping the image of TYPE 5 in FIG. 4 to the corresponding three-dimensional display model. In the case of FIG. 8, the electric power buses 27a to 27d are displayed as the ground color (indicated by “hatching” in the figure), indicating that there is no abnormality. The circuit breakers 19a and 19b are in the “ON” state indicated by “red” (indicated by “black” in the figure), while the circuit breakers 19c and 19d are indicated by “green” (indicated by “white” in the figure). The displayed “cut” state. Reference numerals 1B, 2B, and 3B denote transformers, which are drawn as background images.

  As described above, according to the monitoring panel display device and the monitoring panel display method of the present invention, the state of the facility or equipment group to be monitored at a certain time point is displayed on the appropriate display device 10 as a monitoring panel image. Can do. On the other hand, from the remote monitoring devices 13a, 13b, 13c... Shown in FIG. 1, various measurement signal data representing the state of the facility or equipment group to be monitored are sequentially transmitted to the monitoring panel controller 12. In order to display this as a monitoring board image in real time, it is necessary to rewrite the monitoring board image at regular time intervals. For this reason, the CPU 2 requests the monitor panel controller 12 to transmit the telemeter signal data at regular time intervals, for example, every 0.5 seconds, and displays all the displays to be displayed based on the transmitted telemeter signal data. The display device image is read out, and the read display device image is associated with the information about the position to be displayed in the background image 14 of the display device image specified in the layout table 7 and transmitted to the GPU 8. It becomes.

  The GPU 8 generates a display three-dimensional model in the same procedure as described above, and places the generated display three-dimensional model in the three-dimensional space based on the position information to be displayed. At this time, since it is not necessary to rewrite the background image, the previously used arrangement data in the three-dimensional space can be used as it is for the background three-dimensional model. In addition, since it is not necessary to change the viewpoint 25 and the position of the light source, the previous data can be used as it is.

  Subsequently, the GPU 8 performs conversion into a two-dimensional image by the same procedure as described above, performs texture mapping of the subdivision background image and the display image, and obtains a monitoring board image to be displayed. If the texture-mapped data of the previously used subdivision background image is available, the texture mapping can be omitted for the subdivision background image. Although it depends on the performance of the GPU 8 and the size of the monitoring board image to be displayed, it usually takes 0.5 seconds to obtain the monitoring board image to be displayed by rendering after reading the display image based on the telemeter signal. There is no particular problem in updating the monitoring panel image at a time interval of 0.5 seconds. Note that the time interval for updating the monitoring panel image is not limited to 0.5 seconds, and may be longer or may be shorter if the performance of the GPU 8 permits. As described above, at least a display image is updated at predetermined time intervals, and by repeatedly creating a monitoring panel image, the state of the facility or equipment group to be monitored is displayed as a monitoring panel image in real time. It becomes possible.

  FIG. 9 shows a state where the monitoring board image shown in FIG. 8 is updated. That is, of the two electric station buses 27a and 27b in the upper and lower systems, an abnormality occurs in the electric station bus 27b. Therefore, the display of the electric station bus 27b is “red” (indicated by “black” in the drawing) indicating the abnormality. ing. In addition, because an abnormality has occurred in the electric power station bus 27b, the circuit breakers 19a and 19b of the transformer 3B connecting the electric power station bus 27b and the electric power station bus 27c are in a “cut” state, which is the case of the circuit breakers 19a and 19b. This is indicated by the display changing from “red” to “green” (“black” to “white” in the figure). The electric power buses 27a, 27c, and 27d are not abnormal and are displayed as the ground color (indicated by “hatching” in the figure). Similarly, the color of the ground in the electric station name display 20 changes from “white” indicating a light-off state to “amber” (indicated by hatching in the figure), indicating that there is an abnormality. Moreover, the numerical value of the numerical indicator 21 displays the electric power passing through the transformer as a numerical value display.

  In order to alert the monitoring staff that the display of the electric power station bus 27b has changed to “red” indicating an abnormality, for example, the “red” display of the electric power station bus 27b is blinked at a predetermined time interval. Flicker display. The flicker display command can be included in the telemeter signal data by providing a bit for specifying whether or not the flicker display is necessary in the telemeter signal data, for example. When such a flicker display command is issued for a specific display image, the CPU 2 or the GPU 8 is turned off every other time when updating the monitoring panel image separately from the “red” display command by the telemeter signal data. The color designation for the display device image is changed so that “white” indicating “” is displayed. For example, when there is a flicker display command for a faulty electric power station bus 27b together with a “red” display command indicating an abnormality, the CPU 2 or the GPU 8 updates the display of the electric power station bus 27b to the monitoring panel image. In accordance with this timing, “red” → “white” → “red” → “white” is switched, and in the monitoring panel image, the display of the electric station bus 27b becomes a flicker display in which “red” flashes. Such a flicker display command can be performed not only for the electric power station bus 27b but also for other indicators, and it is possible to monitor a display whose state has changed, particularly a numerical indicator whose value has changed. Can be used to call attention. The flicker display can be terminated by eliminating the abnormal state, elapse of a predetermined time, completion of updating of the monitoring panel image a predetermined number of times, confirmation operation by a monitor, and the like.

  The display area can be changed by the monitoring board image by changing the position of the viewpoint set in the three-dimensional space. That is, as shown in FIG. 10, when the viewpoint 25 is set at the position shown in the figure, the monitoring board image projected on the view screen 26 is an area indicated by A in the figure, but the viewpoint 25 is set to the viewpoint 25 ′. When the position is moved parallel to the texture mapping surface of the background three-dimensional model to the position, the monitoring board image becomes an area indicated by A ′ in the figure projected onto the view screen 26 ′. This makes it possible to display an arbitrary area of a wide monitoring panel as an image. Note that the area to be displayed can be specified or moved on the display screen via an appropriate input device such as a mouse or a keyboard. Also, create a list table of names of facilities and equipment displayed as background images and display images, display them appropriately as a window on the display screen, and specify the names on the displayed table with a mouse or the like. Thus, the area displayed as the monitoring board image may be changed. Furthermore, you may make it change the area | region displayed as a monitoring board image by carrying out the voice input of the name of the plant | facility and equipment which should be displayed as a monitoring board image via a voice input device.

  The monitoring board display device and the monitoring board display method of the present invention can be provided with means or steps for enlarging or reducing the displayed monitoring board image. That is, in the monitoring panel display device and the monitoring panel display method of the present invention, in order to enlarge or reduce the displayed monitoring panel image, the background image storage means 4 stores a set of a plurality of subdivided background images having different drawing magnifications. This can be done by providing means or steps for selecting a set of subdivided background images to be read from the background image storage means 4 in response to the designated display magnification or enlargement / reduction instruction. For example, in the example shown in FIG. 2, one monitoring panel image is composed of a total of 72 subdivided background images of 12 columns by 6 rows, but the size of one subdivided background image is not changed. If the background image drawn on each subdivision background image is enlarged, the number of subdivision background images required to construct one monitoring board image increases. For example, in FIG. The size of the model 23 is larger than the size of the region A or A ′ converted into the two-dimensional region, and the monitoring board image is enlarged.

  Conversely, if the background image drawn on each subdivided background image is reduced without changing the size of one subdivided background image, the number of subdivided background images required to construct one monitoring board image decreases. For example, in FIG. 10, if the size of the background three-dimensional model 23 constituting one monitoring board image is the same as or smaller than the size of the area A or A ′ converted into the two-dimensional area, the monitoring board Can be displayed as a single monitoring panel image. In this case, the monitoring board image is reduced. In the monitoring panel display device and the monitoring panel display method of the present invention, a plurality of sets of subdivided background images having different drawing magnifications are stored in the background image storage means 4 in accordance with a display magnification change command. By selecting a set of subdivided background images to be read from the background image storage means 4, the monitoring panel image displayed on the display device 10 can be enlarged or reduced.

  As described above, in the monitoring panel display device and the display method of the present invention, the image is not simply enlarged or reduced on the software based on the display magnification change instruction or the display image enlargement or reduction instruction. Since a set of subdivided background images that are actually enlarged or reduced and stored is stored and used in such a manner that the images are not coarsened even if the display image is enlarged, Further, even if the display image is reduced, the figure and characters are not crushed, and the image can always be clearly displayed.

  Regarding the display image, a plurality of sets of display images having different drawing magnifications are stored in the display image storage means 5 in stages, and the display image storage means 5 stores the display image based on the display magnification change command. Of course, a set of display images to be read may be selected. However, the display image is a relatively simple image, and even when enlarged or reduced on the software, the image is less likely to be disturbed. Therefore, the display image matches the drawing magnification of the subdivided background image read from the background image storage means 4. Thus, it can be used by being enlarged or reduced as appropriate on the software. In addition, when the drawing magnification of the subdivision background image read from the background image storage unit 4 is changed, the background image is also rendered including the arrangement of the corresponding background 3D model in the 3D space and texture mapping. Needless to say, it is necessary to perform processing and update the monitoring panel image.

  As described above, the display image can be greatly enlarged or reduced. However, if the display image is slightly enlarged or reduced, for example, in FIG. 10, the position of the viewpoint 25 is perpendicular to the background three-dimensional model 23. It can be done by moving to. That is, when the viewpoint 25 is brought close to the background three-dimensional model 23, the size of the area A projected onto the view screen 26 is reduced, so that the two-dimensionally converted image is enlarged, and conversely, the viewpoint 25 is changed to the background three-dimensional model. When moving away from the model 23, the size of the area A projected on the view screen 26 increases, and the two-dimensionally converted image is reduced. In the monitoring panel display device and the display method of the present invention, a plurality of sets of subdivided background images having different drawing magnifications are prepared in advance, and the display image is enlarged and reduced by switching and used, and the viewpoint is moved. By using a combination of enlargement and reduction of a display image, it is possible to perform smooth enlargement and reduction of the image and to obtain an advantage that the clearness of the image is not impaired.

  When there are a plurality of types of monitoring board images to be displayed, a plurality of sets of subdivided background images 15, 15, 15... Corresponding to each monitoring board image are stored in the background image storage means 4. In addition, a plurality of sets of display device images corresponding to the respective monitoring panel images are stored in the display device image storage means 5, and a plurality of types of design tables 6 and layout tables 7 are stored in the storage device 3. The monitor panel image to be displayed can be changed as appropriate by appropriately changing the subdivision background image set, display image set, design table 6 and layout table 7 to be used. The display image set and the design table 6 do not need to be changed if there is no need to change the monitoring panel image.

The computer 1 displays the monitoring board image on the monitoring board 10 in accordance with the above-described procedure.

  The training computer 28 displays, for example, a monitor image similar to the monitor screen of the command stand in the actual power supply command room on the trainee monitors 30, 30, 30, and the trainer monitors 32, 32, 32. , 32 also display a monitor image for the trainer. Of course, these monitor images correspond to the current state of the power system displayed on the monitoring panel 10 based on the simulated measurement signal data generated by the training computer 28.

  The training computer 28 changes the state of the power system to be trained based on a preset program or based on instructions from the training trainer tables 31a, 31b, 31c, 31d, The change is sent to the monitoring board controller 12 as a change in the simulated measurement signal data, and the monitoring board 10 changes the displayed monitoring board image. At the same time, the monitor images displayed on the trainee monitors 30, 30, and 30 are also changed, and the trainee is the trainee who is installed on his / her table and the monitor panel image of the monitor 10 that has changed. In response to changes in the monitor images displayed on the monitors 30, 30, 30, appropriate operations and instructions are executed, and training is performed.

A plurality of types of tables 7 are stored in the storage device 3, and the monitor panel image to be displayed is changed by appropriately changing the subdivided background image set, display image set, design table 6, and layout table 7 to be used. It is possible to change and respond to changes in the power system to be trained as needed.

  In the above-described example, the monitoring panel display device and the monitoring panel display method of the present invention are used only for displaying the monitoring panel image on the monitoring panel 10. The board display method can also be used to display monitor images on the trainee monitors 30, 30, 30, and the trainer monitors 32, 32, 32, 32.
