BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Embodiment 1

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 is provided with a data processing apparatus 1 and a display data generating apparatus 2. [

The data processing apparatus 1 performs processing for reducing the amount of data per file for the acquired data (simulation data). 1, the data processing apparatus 1 includes an acquisition unit 101, a partitioning unit 102, and a recording unit 103. [

The acquisition unit 101 acquires simulation data, which is the simulation execution result, from an external device (simulation execution device). Here, the obtaining unit 101 obtains, as simulation data, simulation data of a substance to be acted on by the device, and simulation data of a portion of the device acting on the substance and a portion of the device acting on the substance, respectively do. These simulation data are each composed of one file.

The division unit 102 divides the simulation data acquired by the acquisition unit 101 into a plurality of files in accordance with the division condition. Here, the division condition for the simulation data of the material includes a condition about a time, a condition about a space where the apparatus is installed, and a condition combining the above two conditions.

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

The hardware configuration for implementing the data processing apparatus 1 includes a receiving apparatus 51, a processor 52, and a memory 53 as shown in Fig. 2, for example.

2, the acquisition unit 101 shown in FIG. 1 is realized by the reception device 51. In FIG. The recording unit 103 shown in Fig. 1 is realized by the memory 53. Fig. 1 is realized by the processor 52 that executes the program recorded in the memory 53. [ A plurality of processors 52 and a plurality of memories 53 may cooperate to execute the above function.

The display data generation device 2 is for generating display data for display on a display (not shown) using data processed by the data processing device 1, and is used for a tablet PC, a notebook PC, a mobile PC And other low-cost general-purpose PCs. 1, the display data generating device 2 includes a designation accepting unit 201, a reading unit 202, a three-dimensional moving image data generating unit 203, and a display data generating unit 204 have.

The designation reception unit 201 accepts 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 reception unit 201 from the recording unit 103 of the data processing apparatus 1. [ The communication between the data processing apparatus 1 and the display data generating apparatus 2 may be performed either online or offline.

The three-dimensional moving image data generation unit 203 generates three-dimensional moving image data from the data read by the reading unit 202. [

The display data generation section 204 generates display data using the three-dimensional moving image data generated by the three-dimensional moving image data generation section 203 and the three-dimensional data of the device. Further, the three-dimensional data of the apparatus is three-dimensional data except for the portion that acts on the substance from the device and the portion that is acted on by the substance, and is prepared in advance. In generating the display data, in addition to the three-dimensional data of the apparatus, three-dimensional data other than the apparatus may also be used.

Next, an operation example of the display system configured as described above will be described. In the following, the case of using simulation data for a rolling mill having a rolling mill 11 (equipment) for rolling a steel material 12 (material) will be described as an example.

In this rolling plant, for example, as shown in Fig. 3, a plurality of rolling mills 11 are arranged on a 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 disposed above and below, respectively. Hereinafter, the work roll 111 is referred to as a roll 111. The clearance between the upper and lower rolls 111 of each rolling mill 11 is set so as to become narrow toward the rolling direction of the steel material 12. [ The steel material 12 heated at a high temperature is interposed between the rolls 111 of the rolling mill 11 so that the steel material 12 is gradually formed into a thin plate.

In the simulation for this rolling plant, the simulation of the steel material 12 and the simulation of the portion of the roll 11 acting as a part of the steel material 12 and the portion of the roll 111 as a part acting by the steel material 12 are performed .

In the simulation of the steel material 12, the surface (plane) in which the one end to the other end are evenly divided in the depth direction (rolling direction) of the steel material 12 and the plane (The width direction x and the height direction y) of the intersection between the divided planes (not limited to the plane) are calculated. The coordinate value (x, y) is associated with the element number (xNum, yNum, zNum) of the lattice point formed by the intersection point and is recorded as the coordinate point together with the elapsed time (second) from the start of the simulation. For each lattice point, parameters such as temperature and flatness indicating the plate shape generated by rolling are also calculated and recorded. In addition, 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 dimension) between the rolls 111, the load and tension acting on the contact between the roll 111 and the steel 12, ) Is calculated and recorded together with the elapsed time (seconds) from the start of the simulation. Further, the load and the 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 apparatus 1, as shown in Fig. 4, first, the acquisition unit 101 acquires simulation data from an external device (step ST401). Here, it is assumed that the obtaining unit 101 obtains the simulation data of the steel material 12 and the simulation data of the roll 111 of the rolling mill 11, respectively.

Here, the amount of data of the simulation data is very large (several GB or more). Therefore, when the simulation data is used as it is and three-dimensional display is performed, a memory capable of reading a large amount of data is needed. Also, reading large amounts of data at one time may lead to delays in processing, and in the worst case, the data may be hung up. Further, even in the case of acquiring simulation data on-line, it takes a long time to acquire simulation data depending on the communication speed. Therefore, realization on a general-purpose PC is difficult.

Also, for example, if it is desired to check the simulation result after 1 minute in the step of reading the simulation data from the start of the simulation to the 5th second, it is necessary to wait until the simulation data after 1 minute is read. Alternatively, it is necessary to stop the reading process and search for the corresponding data in the entire simulation data. Therefore, even in such a case, the process is delayed and it is difficult to realize in a general-purpose PC.

Thus, the division unit 102 divides the simulation data acquired by the acquisition unit 101 into a plurality of files in accordance with the division condition (step ST402). Hereinafter, the simulation data of the steel material 12 and the method of dividing the simulation data of the roll 111 portion of the rolling mill 11 will be described.

First, a method of dividing the simulation data of the steel material 12 will be described. Here, the dividing condition is a condition relating to the space in which the apparatus is installed, and a condition relating 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 intervals of the rolls 111 in the installation space of the rolling mills 11 (F1 to F7). Also, a group divided into spaces is called an object. In the example of Fig. 3, from the insertion port of the steel material 12 to the point immediately before the roll 111 of the rolling mill F1 is referred to as the 0th object (Object.0), and from the rolls 111 of the respective rolling mills F1 to F6, (Object.7 to 6) from immediately below the roll 111 of the rolling mill F7 to 6 meters before the roll 111 of the rolling mill F7 are referred to as first to sixth objects (Objects 1 to 6) , And the end from the end of the seventh object, for example, up to 120 m, is referred to as the eighth object (Object.8).

In the dividing section 102, a division pitch (Register Pitch), which is a reading interval of data with respect to the depth direction of the steel material 12, is set when the dividing process is performed.

Further, in the division unit 102, the division pitch can be made variable for each object. Specifically, in the zero-th object and the eighth object which are regions affected by the roll 111, the dividing pitch in the depth direction is impaired and the data is lightened.

Further, further division is performed for each of the objects at each time DELTA t (seconds) from the start of the simulation.

As described above, by dividing the simulation data for each interval between the rolls 111 and each time from the start of the simulation, simulation data of several GB or more can be divided into data of about several hundreds of kbytes. Therefore, the amount of data per file can be reduced, leading to an increase in processing speed in the display data generating device 2. [ Also, in the object, the object of the time zone in which no parameters such as the temperature and the flatness are held is deleted.

Further, in the three-dimensional display of the rolling plant, there is a case where the heated steel material 12 is expressed as an image having a reality (see Fig. 6). In order to perform such display, the division unit 102 may assign a numerical value exceeding 1 to the luminance value of the lattice point with respect to the data of each object in accordance with the temperature. Thereby, it becomes possible to easily reproduce an image having a reality in the three-dimensional display in the display data generating device 2. [ Details thereof will be described later.

Next, a method of dividing the simulation data of the roll 111 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 the files of the gap, load, tension, and bender load between the rolls 111, respectively.

Further, the file for each data type is further divided for each rolling mill 11 (divided into seven in the example of Fig. 3).

Then, the recording unit 103 records the data divided into the plurality of files by the partitioning unit 102 in association with the corresponding partitioning parameter of the partitioning condition (step ST403). That is, the division file relating to the simulation data of the steel material 12 includes the number of consecutive numbers indicating the time from the start of the simulation, the object number, the divided pitch number in the depth direction (element number of the lattice point) (Element number of the lattice point), coordinate value (x, y), temperature and flatness, luminance value, and the like. The division file relating to the simulation data of the roll 111 of the rolling mill 11 includes data indicating the data type and the equipment number identifying the rolling mill 11 and various data such as a gap between the rolls 111, , Tensile or bender loads).

Next, an operation example of the display data generating device 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 accepting unit 201 accepts designation of the division parameter to be read from the user (step ST501). At this time, the user designates, for example, the time zone in which the simulation result is to be confirmed.

Then, the reading unit 202 reads data associated with the division parameter received by the designation reception unit 201 from the recording unit 103 of the data processing apparatus 1 (step ST502). Here, in the data processing apparatus 1, the simulation data including one file is divided into a plurality of files under a predetermined division condition, and is recorded in association with the corresponding division parameter. This makes it possible to instantaneously read the data corresponding to the division parameter designated by the user. Therefore, the long-term read processing and the search processing as in the conventional art become unnecessary, leading to an increase in processing speed. Also, the reading process by the reading unit 202 may be temporarily stopped by a user operation, and if the reading of data in the time zone specified by the user is not completed, the data in the time zone is read first.

Then, the three-dimensional moving image data generation unit 203 generates three-dimensional moving image data from the data read by the reading unit 202 (step ST503).

Subsequently, the display data generation section 204 generates display data using the three-dimensional moving image data generated by the three-dimensional moving image data generation section 203 and at least three-dimensional data of the device (step ST504) . Further, in the case of the rolling plant, the three-dimensional data of the apparatus is three-dimensional data of the housing portion of the rolling mill 11.

Thereafter, display data is displayed on the display.

Hereinafter, the processing from reading data in a time zone designated by the user to drawing is described. Here, a case where a divided file relating to the simulation data of the steel material 12 is read and drawing is described as an example. It is assumed that the display data generation device 2 has previously examined the recording start time of each object recorded in the recording unit 103 of the data processing apparatus 1. [

In this case, first, the reading unit 202 reads the data of 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 value (x, y) at each divisional 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 lattice point corresponding to the division pitch. Further, the reading section 202 also reads the temperature, the flatness, and the luminance value. When the time of the read object does not fill the recording start time of the object, the read processing for the object is skipped.

Then, the three-dimensional moving image data generation unit 203 creates 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 the vertex number of the serial number. Then, coordinate values (x, y, z) are assigned to each vertex number.

At this time, the allocation is first carried out starting from the coordinate values in the depth direction of the steel material 12 at the forward end in the width direction of the steel material 12, and then shifted one by one in the depth direction. When reaching the end in the depth direction, one is shifted in the negative direction in the width direction, and thereafter, the allocation is made while shifting in the inward direction as described above.

Further, the three-dimensional moving image data generation unit 203 creates numerical values converted into color information in accordance with the display settings, based on the data read by the reading unit 202, from the temperature, the flatness, and the luminance value.

Further, since the polygon constitutes one triangle by combining the three vertices, the number of the constituent vertices is sequentially recorded. The order of designation is selected by referring to the element number of the grid point so that the order of connecting the vertices of the triangle is counterclockwise, and the vertex number corresponding to the coordinate is recorded.

In addition, the three-dimensional moving image data generation unit 203 simultaneously generates a two-dimensional development coordinate value for texture projection. At this time, one triangle of polygons composed of three vertices and polygons adjacent to the polygon are treated as one set of tetragons, and the maximum size is set on a square two-dimensional plane having a length of one side of 1 Respectively.

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

Thereafter, the display data generation unit 204 performs polygon rendering processing. If the creation of the polygon generation data in the specified time period is not completed, the data is created before the polygon rendering process. On the other hand, when polygon generation data exists, the polygon rendering process is performed based on the data. Further, in the display data generation unit 204, the drawing process is not performed on the object space in which the steel material 12 has not reached.

Next, an example of display data generated by the display data generation unit 204 is shown.

6 shows a part of the rolling of the steel material 12 reproduced in a moving picture. In Fig. 6, in addition to the conventional visualization of the rolling simulation, there is a reality expression such as actually photographing the steel material 12 heated at a high temperature.

In the case where the expression as 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 the calculation load is high. The animation shown in Fig. 6 is data that is not used for analysis and verification of the rolling plant. Thus, in the present invention, reproduction is performed in a pseudo-expression in which the calculation load is low.

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 in accordance with the temperature of each lattice point. When three-dimensional drawing is performed in the three-dimensional moving image data generation unit 203, a luminance value is assigned to a rendering pixel of the steel material 12. If the value is a certain value or more (for example, 1.1 or more) A process of expanding the color of the rendering pixel is performed. By performing such processing, the display as shown in Fig. 6 can be performed by the two-dimensional processing, and the calculation load can be suppressed. Also, the luminance of the rendering pixel is normally expressed in a range from 0, which is black, to 1, which is white. Therefore, the drawing pixel having a value exceeding 1 is an intentionally designated part, and the other part (for example, the white part of the rolling mill 11) is not expanded and becomes the appearance of light emitted.

Further, conventionally, a high-performance simulation PC is used to perform three-dimensional display in only one object space. Further, even with such limited three-dimensional display, it takes a lot of time (about one day to one day from the half day) in the pre-calculation. On the other hand, in the present invention, since the amount of data per file of the data to be read is made small even in the inexpensive general-purpose PC, the entire rolling plant as shown in Fig. 6 can be easily displayed in three dimensions.

Further, in the present invention, it is configured in a form independent of the execution device of the simulation, specifically in the confirmation of the simulation result. This makes it possible to limit the functions, to provide easy operability to the user, and to suppress the ability of the general-purpose PC on which the display data generation device 2 is mounted to be low.

Also, the sub-selection items included in the display content manipulation function unit 301 are displayed in the lower part in the same manner only when various functions are selected. Thereby, it is possible to provide an intuitive operability to the user, and to prevent confusion accompanying access to the objective function. For example, Fig. 7 shows a case in which the camera angle selection unit 3011, which is an example of a sub-selection item of the display content operation function unit 301, is displayed. The camera angle selecting unit 3011 can perform three-dimensional display in a desired direction. Further, the user can freely change the angles other than the fixed camera angle by operating the pointer.

Further, the time manipulation function unit 302 colors the area at the time when the reading of the simulation data is completed, so that the progress of the current reading process can be confirmed at a glance.

As described above, according to the first embodiment, the acquisition section 101 for acquiring the simulation data, the division section 102 for dividing the simulation data acquired by the acquisition section 101 into a plurality of files according to the division condition, And a recording unit 103 for recording the data divided into the plurality of files by the division unit 102 in association with the corresponding division parameter of the division condition, A three-dimensional moving image data generation unit 203 for generating three-dimensional moving image data from the data read by the reading unit 202, a three-dimensional moving image data generation unit 203 for generating three- (2) having a display data generation unit (204) for generating display data using at least three-dimensional moving picture data of the apparatus and three-dimensional moving picture data generated by the display unit Because, even if a general-purpose PC to suppress the processing delay can be made a three-dimensional display. As a result, by using the simulation data used for analysis and verification, it is possible to realize the appeal of technical commentary and technical effort and the three-dimensional display that can be utilized by the visitor in a meeting room, an exhibition, or the like.

In the above description, the acquisition unit 101 acquires simulation data of a substance to be acted on by the device, and simulation data of a portion of the device acting on the substance and a portion of the device acting on the substance . However, the present invention is not limited to this, and it is also possible to acquire only simulation data of a substance to be operated by the device.

Embodiment 2 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 the second embodiment shown in Fig. 8 is obtained by adding the empty data deletion unit 104 to the configuration example of the display system shown in Fig. Other configurations are the same, and the same reference numerals are given and only different parts are described.

The blank data deletion unit 104 deletes the blank data from the file divided by the division unit 102. [

The recording unit 103 also records the data of the file in which the blank data is deleted by the blanking unit 102 and the blank data is deleted by the blank data deletion unit 104 in association with the partitioning parameter.

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

Embodiment 3:

Embodiment 3 shows a case where data for animation display and data for detailed display (single-sided display) are separately recorded. 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 the third embodiment shown in Fig. 9 is obtained by adding the internal data deletion unit 105 to the configuration example of the display system shown in Fig. Other configurations are the same, and the same reference numerals are given and only different parts are described.

The internal data deletion unit 105 deletes the internal data from the file divided by the partitioning unit 102. [ Here, the internal data refers to simulation data relating to the inside of the surface other than the surface of the material and the equipment unnecessary for displaying the animation.

In addition to the data divided into a plurality of files by the partitioning unit 102, the recording unit 103 records data of the file in which the internal data is deleted by the internal data deletion unit 105, do.

In the animation display that shows only the appearance of the material and the device, the inside of the material and simulation data of the inside of the device are unnecessary. Therefore, this internal data is deleted. Further, data for animation display and data for other details (cross-sectional display such as the steel material 12 and the roll 111) are separately recorded. Thereby, the amount of data for animation display can be further reduced, leading to a higher speed of processing in the display data generating device 2. [

In the above description, the internal data deletion unit 105 is added to the display system according to the first embodiment. 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 the second embodiment, and the same effect can be obtained.

Embodiment 4.

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 the fourth embodiment shown in Fig. 10 is obtained by adding the second division unit 106 to the configuration example of the display system according to the first embodiment shown in Fig. Other configurations are the same, and the same reference numerals are given and the 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 also records the data of the file divided 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 the cross section of the steel material 12 and the roll 111 or the like. In this case, reading of data other than the cross section is unnecessary. So, we break down the file further per division pitch. This makes it possible to further reduce the amount of data per file recorded in the recording unit 103, leading to a higher speed of processing in the display data generating apparatus 2. [

Further, with respect to the data divided for each division pitch, the division unit 102 does not perform division every time from the start of the simulation. That is, data of all the times when the material exists at the point are recorded in the file divided for each division pitch. When performing a single-sided display, predetermined data (for example, seven pieces of data immediately under the roll 111) among the divided data for every division pitch is read.

In the above description, the second division unit 106 is added to the display system according to the first embodiment. However, the present invention is not limited to this, and the second divisional section 106 may be added to the display system according to the second and third embodiments.

In the above description, the simulation data for the rolling plant having the rolling mill 11 (equipment) for rolling the steel material 12 (material) is used as an example, but the present invention is not limited thereto. For example, the present invention can also be applied to a case where three-dimensional display is performed using simulation data for air conditioning equipment (equipment) and air (material) which is hot air or cold air flowing out from the air conditioning equipment.

The present invention can be modified within the scope of the invention, and any component of the embodiment or any component of the embodiment can be omitted.

The display system according to the present invention can be applied to a data processing apparatus that can perform three-dimensional display by suppressing a processing delay compared with the conventional configuration and reduce the amount of data per file with respect to the acquired data, And a display data generation device for generating display data using the data processed by the display data generation device.
