Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration example of a display system according to Embodiment 1 of the present invention.
As shown in FIG. 1, the display system includes a data processing device 1 and a display data generation device 2.

The data processing device 1 performs processing for reducing the amount of data per file for acquired data (simulation data). As illustrated in FIG. 1, the data processing apparatus 1 includes an acquisition unit 101, a division unit 102, and a recording unit 103.

The acquisition unit 101 acquires simulation data as a simulation execution result from an external device (simulation execution device). Here, the acquisition unit 101 acquires, as simulation data, simulation data of a substance that is acted on by a device, and simulation data of a part that acts on the substance and a part that is acted on by the substance. It shall be. Each of these simulation data is composed of one file.

The division unit 102 divides the simulation data acquired by the acquisition unit 101 into a plurality of files according to the division condition. Here, examples of the division condition for the simulation data of the substance include a condition relating to time, a condition relating to a space in which the device is installed, and a condition combining both of the above conditions.

The recording unit 103 records the data divided into a plurality of files by the dividing unit 102 in association with the division parameters (time, position, etc.) corresponding to the division conditions.

Note that the hardware configuration for realizing the data processing device 1 includes a receiving device 51, a processor 52, and a memory 53 as shown in FIG.
In FIG. 2, the acquisition unit 101 shown in FIG. Also, the recording unit 103 shown in FIG. 1 is implemented by a processor 52 that executes a program recorded in the memory 53. In addition, a plurality of processors 52 and a plurality of memories 53 may cooperate to execute the above function.

The display data generation device 2 generates display data to be displayed on a display (not shown) using the data processed by the data processing device 1, such as a tablet PC, a notebook PC, or a mobile PC. It is mounted on an inexpensive general-purpose PC. As shown in FIG. 1, the display data generating apparatus 2 includes a designation receiving unit 201, a reading unit 202, a three-dimensional moving image data generating unit 203, and a display data generating unit 204.

The designation receiving unit 201 receives designation of a division parameter to be read from the user.
The reading unit 202 reads data associated with the division parameter received by the designation receiving unit 201 from the recording unit 103 of the data processing apparatus 1. Note that the communication between the data processing device 1 and the display data generation device 2 may be performed online or offline.

The 3D moving image data generation unit 203 generates 3D moving image data from the data read by the reading unit 202.
The display data generation unit 204 generates display data using the 3D moving image data generated by the 3D moving image data generation unit 203 and the 3D data of the device. Note that the three-dimensional data of the device is data that is three-dimensionalized except for a location where the substance is applied from the device and a location where the substance is applied, and is created in advance. In generating display data, three-dimensional data other than the device may be used in addition to the three-dimensional data of the device.

Next, an operation example of the display system configured as described above will be described. In addition, below, it demonstrates as an example the case where the simulation data with respect to the rolling plant provided with the rolling mill 11 (equipment) which rolls the steel material 12 (substance) is used.

In this rolling plant, for example, as shown in FIG. 3, a plurality of rolling mills 11 are arranged on the production line. In the example of FIG. 3, seven rolling mills F1 to F7 are arranged. In each rolling mill 11, a work roll 111 and a backup roll 112 are respectively arranged above and below. Hereinafter, the work roll 111 is referred to as a roll 111. Although not shown, the gap between the upper and lower rolls 111 of each rolling mill 11 is set so as to become narrower in the rolling direction of the steel material 12. Then, the steel material 12 heated to a high temperature is bitten between the rolls 111 of these rolling mills 11 so that the steel material 12 is gradually formed into a thin plate shape.

In the simulation for this rolling plant, the simulation of the steel material 12 and the part of the roll 111 that is the location where the steel material 12 of the rolling mill 11 acts and the location where the steel material 12 acts are performed.

In the simulation of the steel material 12, a surface (plane) obtained by equally dividing the steel material 12 from one end to the other end in the depth direction (rolling direction), and a surface obtained by dividing the steel material 12 by a predetermined number in the width direction and the height direction, respectively. The coordinate value (width direction x, height direction y) of the intersection with (not necessarily a plane) is calculated. This coordinate value (x, y) is associated with the element number (xNum, yNum, zNum) of the lattice point constituted by the intersection point, and is recorded as a coordinate point together with the elapsed time (seconds) from the start of the simulation. For each lattice point, parameters such as temperature and flatness representing the plate shape generated by rolling are also calculated and recorded. Since the simulation space in the depth direction of the steel material 12 is equally divided, the recording of the coordinate value (z) is omitted.

In the simulation of the roll 111 portion of the rolling mill 11, the gap (gap size) between the rolls 111, the load and tension acting on the contact point between the roll 111 and the steel material 12, and the bender load acting on the roll 111 are calculated, and the simulation is started. It is recorded with the elapsed time (seconds) from. The load and tension have a distribution in the width direction.

First, an operation example of the data processing apparatus 1 will be described with reference to FIG.
In the operation example of the data processing device 1, as shown in FIG. 4, the acquisition unit 101 first acquires simulation data from an external device (step ST401). Here, the acquisition part 101 shall acquire the simulation data of the steel material 12, and the simulation data of the roll 111 part of the rolling mill 11, respectively.

Here, the amount of the simulation data is very large (several GB or more). For this reason, when three-dimensional display is performed using this simulation data as it is, a memory capable of reading an enormous amount of data is required. In addition, reading a huge amount of data at a time leads to a delay in processing, and in the worst case, there is a possibility of hanging up. Also, when acquiring simulation data online, it takes a long time to acquire depending on the communication speed. Therefore, realization with a general-purpose PC is difficult.
Further, for example, when it is desired to check the simulation result after one minute at the stage where the simulation data from the start of the simulation to the fifth second is read, it is necessary to wait until the simulation data after one minute is read. Alternatively, it is necessary to interrupt the reading process and retrieve the corresponding data from the entire simulation data. Therefore, even in such a case, it leads to processing delay and is difficult to be realized on a general-purpose PC.

Therefore, the dividing unit 102 divides the simulation data acquired by the acquiring unit 101 into a plurality of files according to the dividing condition (step ST402). Hereinafter, the division | segmentation method with respect to the simulation data of the steel material 12 and the simulation data of the roll 111 part of the rolling mill 11 is demonstrated.

First, a method for dividing the simulation data of the steel material 12 will be described. Here, a case is shown in which the division condition is a condition related to a space in which the device is installed and a condition related to time.

In the division of the simulation data of the steel material 12, for example, as shown in FIG. 3, the division is performed at the arrangement interval of the rolls 111 in the installation space of the rolling mill 11 (F1 to F7). One group divided in space is called an object. In the example of FIG. 3, the portion from the insertion opening of the steel material 12 to immediately before the roll 111 of the rolling mill F1 is defined as the 0th object (Object.0), and the next rolling mill F2 to F7 is directly under the roll 111 of each rolling mill F1 to F6. The first to sixth objects (Object. 1 to 6) immediately before the roll 111 are set as the seventh object (Object. 7), for example, 6 m away from immediately below the roll 111 of the rolling mill F7, and 120 m from the end of the seventh object. The preceding is the eighth object (Object.8).

The dividing unit 102 sets a division pitch (Register Pitch) that is a data reading interval in the depth direction of the steel material 12 when performing the above-described division processing.
Further, the division unit 102 can change the division pitch for each object. Specifically, in the 0th object and the 8th object, which are areas not affected by the roll 111, the division pitch in the depth direction is increased to reduce the weight of the data.

Further, the above objects are further divided every time Δt (seconds) from the start of the simulation.
In this way, by dividing the simulation data for each arrangement interval of the rolls 111 and each time from the start of the simulation, simulation data that is several GB or more can be divided into data of about several hundred kilobytes. As a result, the amount of data per file can be reduced, leading to faster processing in the display data generating apparatus 2. It should be noted that in the above objects, objects in time zones that do not have any parameters such as temperature and flatness are deleted.

Moreover, in the three-dimensional display of the rolling plant, there are cases where it is desired to represent the heated steel material 12 with a realistic image (see FIG. 6). In order to perform such display, the dividing unit 102 may assign a numerical value exceeding 1 to the luminance value of the grid point for each object data in accordance with the temperature. This makes it possible to easily reproduce a realistic image in the three-dimensional display in the display data generation device 2. Details thereof will be described later.

Next, a method for dividing simulation data of the roll 111 portion of the rolling mill 11 will be described.
In the division of the simulation data of the roll 111 portion of the rolling mill 11, the division is performed for each data type. That is, the simulation data is divided into files of gaps between the rolls 111, loads, tensions, and bender loads.
Further, the file for each data type is further divided for each rolling mill 11 (divided into seven in the example of FIG. 3).

Next, the recording unit 103 records the data divided into a plurality of files by the dividing unit 102 in association with the division parameter corresponding to the division condition (step ST403). That is, the division file relating to the simulation data of the steel material 12 includes a serial number indicating the time from the start of the simulation, an object number, a division pitch number in the depth direction (element number of the grid points), and a division number in the width direction (of the grid points). Element number), division number in the height direction (element number of grid points), coordinate values (x, y), data indicating parameters such as temperature and flatness, and luminance value are included. Further, the division file relating to the simulation data of the roll 111 portion of the rolling mill 11 includes data type, data indicating a device number for identifying the rolling mill 11, and various data (gap, load, tension, or vendor load between the rolls 111). And are included.

Next, an operation example of the display data generating apparatus 2 will be described with reference to FIG.
In the operation example of the display data generating device 2, as shown in FIG. 5, first, the designation receiving unit 201 receives designation of a division parameter to be read from the user (step ST501). At this time, the user designates, for example, a time zone in which the simulation result is desired to be confirmed.

Next, the reading unit 202 reads data associated with the division parameter received by the designation receiving unit 201 from the recording unit 103 of the data processing apparatus 1 (step ST502). Here, the data processing apparatus 1 divides simulation data composed of one file into a plurality of files under a predetermined division condition, and records them in association with corresponding division parameters. Therefore, data corresponding to the division parameter specified by the user can be read out instantaneously. This eliminates the need for a long-time reading process and search process as in the prior art, leading to an increase in processing speed. Note that the reading process by the reading unit 202 can be temporarily stopped by a user operation. If reading of data in a time zone designated by the user is not completed, the data in that time zone is read preferentially.

Next, the 3D moving image data generation unit 203 generates 3D moving image data from the data read by the reading unit 202 (step ST503).

Next, the display data generation unit 204 generates display data using the 3D moving image data generated by the 3D moving image data generation unit 203 and at least the 3D data of the device (step ST504). In the case of a rolling plant, the three-dimensional data of the equipment is the three-dimensional data of the casing portion of the rolling mill 11.
Thereafter, the display data is displayed on the display.

The following shows the processing from reading data in the time zone specified by the user to drawing. Here, a description will be given by taking as an example a case where a division file related to simulation data of the steel material 12 is read and drawn. Further, it is assumed that the display data generation device 2 checks the recording start time of each object recorded in the recording unit 103 of the data processing device 1 in advance.

In this case, first, the reading unit 202 reads the data at the first time in the time zone specified by the user from the recording unit 103 of the data processing apparatus 1. At this time, the reading unit 202 reads the coordinate values (x, y) at each division pitch in the depth direction of the steel material 12. The coordinate value (z) in the depth direction is calculated from the element number (zNum) of the grid point corresponding to the division pitch. The reading unit 202 also reads temperature, flatness, and luminance value. Note that if the read target time is less than the object recording start time, the read processing for the object is skipped.

Next, the three-dimensional moving image data generation unit 203 generates polygon generation data based on the data read by the reading unit 202. At this time, the three-dimensional moving image data generation unit 203 first calculates the number of polygons from the data read by the reading unit 202, and creates serial number vertex numbers. Then, a coordinate value (x, y, z) is assigned to each vertex number.
At this time, first, the assignment is started from the forward end in the width direction of the steel material 12 and the closest coordinate value in the depth direction, and then the assignment is performed while shifting one by one in the depth direction. When the end in the depth direction is reached, the assignment is made by shifting by one in the negative direction in the width direction, and then the assignment is performed while shifting in the depth direction as described above.

Also, the three-dimensional moving image data generation unit 203 generates a numerical value converted into color information according to display settings from the temperature, flatness, and luminance value based on the data read by the reading unit 202.

In addition, since a polygon forms a triangle by combining three vertices, the number of the vertices constituting the polygon is recorded in order. The designation order is selected with reference to the element numbers of the grid points so that the order of connecting the vertices of the triangle is counterclockwise, and the vertex numbers corresponding to the coordinates are recorded.

In addition, the 3D moving image data generation unit 203 simultaneously generates 2D development coordinate values for texture projection. In this case, one triangle of three vertices and a polygon adjacent to the hypotenuse are treated as a set of quadrilaterals, and the maximum length on a square two-dimensional plane with one side length of 1. Expand to the size of.

Thereafter, the processing of the reading unit 202 and the three-dimensional moving image data generation unit 203 is performed at the next time. By repeating this, it is possible to read data in a specified time zone and create various data.

Thereafter, the display data generation unit 204 performs polygon drawing processing. If the creation of polygon generation data for the designated time period has not been completed, the creation of the data is executed before the polygon rendering process. On the other hand, if polygon generation data exists, polygon rendering processing is performed based on the data. Further, the display data generation unit 204 does not execute the drawing process on the object space where the steel material 12 has not reached.

Next, an example of display data generated by the display data generation unit 204 will be described.
FIG. 6 shows a part of a moving image of rolling of the steel material 12. In FIG. 6, in addition to the visualization of the existing rolling simulation, a realistic expression as if the steel material 12 heated to a high temperature was actually photographed is performed.

When the expression shown in FIG. 6 is reproduced by the conventional method, the thermal energy for each lattice point of the steel material 12 is calculated from the simulation data, the light energy is calculated from the thermal energy, and then converted into a drawing pixel. Drawing, and the calculation load is high. Moreover, the animation as shown in FIG. 6 is data that is not used for the analysis and verification purposes of the rolling plant. Therefore, in the present invention, reproduction is performed with a pseudo expression with a low calculation load.

Specifically, in the data processing apparatus 1, a numerical value exceeding 1 is assigned to the luminance value of each lattice point of the steel material 12 according to the temperature of each. In the 3D moving image data generation unit 203, when performing 3D drawing, a luminance value is assigned to a drawing pixel of the steel material 12, and if the value is a certain value (eg, 1.1 or more), the drawing pixel Performs processing to expand the color. By performing such processing, the display as shown in FIG. 6 can be performed by two-dimensional processing, and the calculation load can be suppressed. The luminance of the drawing pixel is usually expressed in a range from 0 which is black to 1 which is white. Therefore, a drawing pixel having a value exceeding 1 is a part that is intentionally specified, and the other part (for example, a white part of the rolling mill 11) does not appear to expand and emit light.

Conventionally, three-dimensional display is performed only in one object space using a high-performance simulation PC. Further, even in such a limited three-dimensional display, a lot of time (about half a day to about a day) is required for pre-calculation. On the other hand, in the present invention, even with an inexpensive general-purpose PC, since the data amount per file of data to be read is reduced, the entire rolling plant as shown in FIG. 6 can be easily displayed in three dimensions. It becomes possible.

Further, in the present invention, it is specialized in the confirmation work of the simulation result, and is configured in a form independent of the simulation execution apparatus. Thereby, functions can be limited, easy operability can be provided to the user, and the ability of the general-purpose PC on which the display data generating device 2 is mounted can be kept low.

Further, the sub-selection items included in the display content operation function unit 301 are also displayed at the bottom in the same manner only when various functions are selected. As a result, intuitive operability for the user can be provided, and confusion prevention associated with access to the target function is realized. For example, FIG. 7 illustrates a case where a camera angle selection unit 3011 that is an example of a sub-selection item of the display content operation function unit 301 is displayed. The camera angle selection unit 3011 can perform a three-dimensional display viewed from a desired direction. Furthermore, the user can freely change to an angle other than a fixed camera angle by operating the pointer.
Further, the time operation function unit 302 colors the region of the time zone in which the reading of the simulation data is completed, so that the current reading processing progress status can be confirmed at a glance.

As described above, according to the first embodiment, the acquisition unit 101 that acquires simulation data, the division unit 102 that divides the simulation data acquired by the acquisition unit 101 into a plurality of files according to the division condition, and the division unit The data processing apparatus 1 having the recording unit 103 that records the data divided into a plurality of files by the 102 in association with the division parameter corresponding to the division condition, and reads the data associated with the corresponding division parameter from the recording unit 103 A reading unit 202; a 3D moving image data generating unit 203 that generates 3D moving image data from the data read by the reading unit 202; a 3D moving image data generated by the 3D moving image data generating unit 203; and at least a device Display that generates display data using 3D data Since a display data generating apparatus 2 and a data generation unit 204, be a general purpose PC, it is possible to perform three-dimensional display by suppressing processing delay. As a result, using simulation data that has been used for analysis and verification, to realize 3D display that can be used for technical explanations, appeals of technical efforts, and attracting customers in places such as conference rooms or exhibitions. Can do.

In the above, a case is shown where the acquisition unit 101 acquires both the simulation data of the substance acted on by the device and the simulation data of the location where the material acts on the device and the location acted on by the material. It was. However, the present invention is not limited to this, and only simulation data of a substance that is acted on by the device may be acquired.

Embodiment 2. FIG.
FIG. 8 is a diagram showing a configuration example of a display system according to Embodiment 2 of the present invention. The configuration example of the display system according to Embodiment 2 shown in FIG. 8 is obtained by adding an empty data deletion unit 104 to the configuration example of the display system shown in FIG. Other configurations are the same, and only the different parts are described with the same reference numerals.

The empty data deleting unit 104 deletes empty data from the file divided by the dividing unit 102.
The recording unit 103 records the data of the file that has been divided into a plurality by the dividing unit 102 and from which the empty data is deleted by the empty data deleting unit 104 in association with the division parameter.

For example, in the simulation of the roll 111 portion of the rolling mill 11, the portion where the steel material 12 has not reached is a portion where no tension or the like is generated, and normally zero data such as 0 is recorded. However, this empty data is not necessary for three-dimensional display. Therefore, by deleting this empty data, the data amount of each file recorded in the recording unit 103 can be further reduced, and the processing in the display data generating apparatus 2 can be speeded up.

Embodiment 3 FIG.
The third embodiment shows a case where animation display data and detail display (cross-section display) data are recorded separately. FIG. 9 is a diagram showing a configuration example of a display system according to Embodiment 3 of the present invention. The configuration example of the display system according to Embodiment 3 shown in FIG. 9 is obtained by adding an internal data deletion unit 105 to the configuration example of the display system shown in FIG. Other configurations are the same, and only the different parts are described with the same reference numerals.

The internal data deleting unit 105 deletes internal data from the file divided by the dividing unit 102. Here, the internal data refers to simulation data relating to the inside other than the material and the surface of the device which are not necessary for displaying the animation.
In addition to the data divided into a plurality of files by the dividing unit 102, the recording unit 103 separately records the data of the file from which the internal data is deleted by the internal data deleting unit 105 in association with the division parameter.

In the animation display that displays only the appearance of the substance and device, the simulation data inside the substance and the device are not required. Therefore, this internal data is deleted. Moreover, the data for animation display and the data for other detailed display (section display of steel material 12 and roll 111 etc.) are recorded separately. As a result, the amount of data for animation display can be further reduced, and the processing in the display data generation device 2 can be speeded up.

In the above description, the case where the internal data deletion unit 105 is added to the display system according to the first embodiment has been described. However, the present invention is not limited to this, and the internal data deletion unit 105 may be added to the display system according to Embodiment 2, and the same effect can be obtained.

Embodiment 4 FIG.
FIG. 10 is a diagram showing a configuration example of a display system according to Embodiment 4 of the present invention. The configuration example of the display system according to Embodiment 4 shown in FIG. 10 is obtained by adding the second dividing unit 106 to the configuration example of the display system according to Embodiment 1 shown in FIG. Other configurations are the same, and the same reference numerals are given and description thereof is omitted.

The second division unit 106 divides the file divided by the division unit 102 into a plurality of files for each division pitch.
The recording unit 103 records the data of the file divided into a plurality by the dividing unit 102 and divided by the second dividing unit 106 for each division pitch in association with the division parameter.

In the present invention, it is also possible to display cross sections of the steel material 12, the roll 111, and the like. In this case, it is not necessary to read data other than the cross section. Therefore, the file is further subdivided for each division pitch. As a result, the amount of data per file recorded in the recording unit 103 can be further reduced, and the processing in the display data generating apparatus 2 can be speeded up.
Note that the data divided for each division pitch is not divided by the division unit 102 every time Δt from the start of simulation. That is, the data of all the time when the substance exists at the point is recorded in the file divided for each division pitch. In addition, when performing cross-sectional display, predetermined data (for example, data for seven locations immediately below the roll 111) is read out of the data divided for each division pitch.
