Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Fig. 1 is a diagram showing an example of the configuration 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 generating device 2.
The data processing apparatus 1 performs the following processing: the amount of data of one file on average is reduced for acquired data (analog data). As shown in fig. 1, the data processing apparatus 1 includes an acquisition unit 101, a dividing unit 102, and a recording unit 103.
The acquisition unit 101 acquires simulation data as a result of simulation execution from an external device (simulation execution device). Here, the acquisition unit 101 acquires, as simulation data, simulation data of a substance acted on by the machine, and simulation data of a position acted on by the substance and a position acted on by the substance in the machine. These simulation data are each composed of one file.
The dividing unit 102 divides the simulation data acquired by the acquiring unit 101 according to the dividing conditions. Here, as the division condition of the simulation data for the substance, a condition related to time, a condition related to a space where the device is installed, and a condition in which the above two conditions are combined are listed.
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.
As shown in fig. 2, for example, the hardware configuration for realizing the data processing device 1 includes a receiving device 51, a processor 52, and a memory 53.
In fig. 2, the acquisition unit 101 shown in fig. 1 is realized by the reception device 51. The recording unit 103 shown in fig. 1 is realized by the memory 53. The divider 102 shown in fig. 1 is realized by the processor 52 executing a program recorded in the memory 53. In addition, the above functions may also be performed by a plurality of processors 52 and a plurality of memories 53 in combination.
The display data generating device 2 generates display data for display on a display (not shown) using the data processed by the data processing device 1, and the display data generating device 2 is mounted on an inexpensive general-purpose PC such as a tablet PC, a notebook PC, or a mobile PC. As shown in fig. 1, the display data generating device 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 specification receiving unit 201 receives specification of a division parameter to be read from a 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. The communication between the data processing device 1 and the display data generating device 2 may be performed on-line or off-line.
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 generator 204 generates display data using the three-dimensional moving image data generated by the three-dimensional moving image data generator 203 and the three-dimensional data of the device. The three-dimensional data of the machine is data that is three-dimensional except for a position on which the material is acted by the machine and a position on which the material is acted, and is created in advance. In addition, in the generation of the display data, three-dimensional data other than the machine may be used in addition to the three-dimensional data of the machine.
Next, an operation example of the display system configured as described above will be described. In the following, a case will be described as an example where simulation data for a rolling mill including a rolling mill 11 (equipment) that rolls a steel material 12 (material) is used.
In this rolling facility, for example, as shown in fig. 3, a plurality of rolling mills 11 are arranged in a production line. In the example of fig. 3, 7 rolling mills F1 to F7 are arranged. Further, work rolls 111 and support rolls 112 are disposed vertically on each rolling mill 11. 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 to be narrower in the rolling direction of the steel material 12. Then, the steel material 12 heated to a high temperature is engaged between the rolls 111 of the rolling mill 11, and the steel material 12 is gradually formed into a thin plate shape.
In the simulation of the rolling facility, the simulation of the steel material 12 and the simulation of the roll 111 portion, which is the position of the rolling mill 11 on which the steel material 12 acts and the position on which the steel material 12 acts, are performed.
In the simulation of the steel material 12, coordinate values (in the width direction x and the height direction y) of intersection points between a surface (plane) obtained by dividing the steel material 12 equally from one end to the other end in the depth direction (rolling direction) and surfaces (not limited to planes) obtained by dividing the steel material 12 by a predetermined number in the width direction and the height direction are calculated. The coordinate value (x, y) is associated with an element number (xNum, yNum, zNum) of a lattice point formed by the intersection, and is recorded as a coordinate point together with an elapsed time (second) from the start of the simulation. Further, parameters such as the calculated temperature and the flatness of the plate shape by rolling are also calculated and recorded for each lattice point. Further, since the simulation space in the depth direction of the steel material 12 is divided equally, recording of the coordinate value (z) is omitted.
In the simulation of the roll 111 portion of the rolling mill 11, the interval (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 bending load acting on the roll 111 are calculated and recorded together with the elapsed time (seconds) from the start of the simulation. In addition, 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. 4.
In the operation example of the data processing device 1, as shown in fig. 4, first, the acquisition unit 101 acquires analog data from an external device (step ST 401). Here, the acquisition unit 101 is configured to acquire simulation data of the steel material 12 and simulation data of the roll 111 portion of the rolling mill 11, respectively.
Here, the analog data has a very large size (several GB or more). Therefore, when three-dimensional display is performed using the analog data as it is, a memory capable of reading enormous data is required. Further, reading a large amount of data at a time may cause a delay in processing, and in the worst case, may cause an unexpected stop. In addition, even when analog data is acquired online, a long time is required for acquisition due to the communication speed. Therefore, implementation with a general-purpose PC is difficult.
Further, for example, when it is desired to check the simulation result after 1 minute at the stage of reading the simulation data from the start of the simulation to the 5 th second, it is necessary to wait until the simulation data after 1 minute is read. Alternatively, it is necessary to interrupt the reading process and search the entire simulation data for the data. This causes a delay in processing even in such a case, and makes implementation with a general-purpose PC difficult.
Then, the dividing unit 102 divides the simulation data acquired by the acquiring unit 101 into a plurality of files according to the dividing conditions (step ST 402). Next, a method of dividing the simulation data of the steel material 12 and 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, a case is shown in which the division condition is a condition relating to a space in which the machine 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 mill 11(F1 to F7). In addition, a group divided in space is called a target. In the example of fig. 3, the target 0 (object.0) is set from the insertion port of the steel material 12 to the position immediately before the roll 111 of the rolling mill F1, the targets 1 to 6 (object.1 to 6) are set from the position immediately below the roll 111 of each rolling mill F1 to F6 to the position immediately before the roll 111 of the next rolling mill F2 to F7, the target 7 (object.7) is set from the position immediately below the roll 111 of the rolling mill F7 to, for example, 6m, and the target 8 (object.8) is set from the end of the target 7 to, for example, 120 m.
When the dividing unit 102 performs the dividing process, a dividing Pitch (Register Pitch) which is a data reading interval is set in the depth direction of the steel material 12.
In addition, the dividing section 102 can change the dividing pitch for each object. Specifically, in the 0 th and 8 th targets which are regions not affected by the roller 111, the division pitch in the depth direction is increased, and the weight of data is reduced.
The targets are further divided at each time Δ t (second) from the start of simulation.
By dividing the analog data at the arrangement interval of the rollers 111 and at each time from the start of the simulation, it is possible to divide the analog data of several GB or more into several data of about 100 kbytes. This can reduce the average data amount of one file, and increase the speed of processing in the display data generation device 2. Among the above-described targets, a target in a time zone in which one of parameters such as temperature and flatness is not owned is deleted.
In addition, there is a case where the heated steel material 12 is intended to be represented by a real image in the three-dimensional display of the rolling facility (see fig. 6). In order to display the data, the dividing unit 102 may assign a value exceeding 1 to the brightness value of the lattice point in advance depending on the temperature for each target data. This makes it possible to easily reproduce a real image in the three-dimensional display in the display data generating device 2. The details of which will be described later.
Subsequently, a description will be given of a method of dividing the simulation data of the roll 111 portion of the rolling mill 11.
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 the interval between the rollers 111, the load, the tension, and the bending load.
Further, the file of each data type is further divided (into 7 in the example of fig. 3) for each rolling mill 11.
Subsequently, the recording unit 103 records the data divided into a plurality of files by the dividing unit 102 in association with the division parameters corresponding to the division conditions (step ST 403). That is, the divided file relating to the simulation data of the steel material 12 contains data indicating parameters such as the number of the serial number indicating the time from the start of the simulation, the target number, the division pitch number in the depth direction (element number of lattice point), the division number in the width direction (element number of lattice point), the division number in the height direction (element number of lattice point), the coordinate values (x, y), the temperature, and the flatness and luminance value. The divided file related to the simulation data of the roll 111 portion of rolling mill 11 includes data indicating the data type, data identifying the machine number of rolling mill 11, and various data (the interval between rolls 111, the load, the tension, or the bending load).
Next, an operation example of the display data generating device 2 will be described with reference to fig. 5.
In an operation example of the display data generating device 2, as shown in fig. 5, first, the specification accepting unit 201 accepts specification of a division parameter to be read from a user (step ST 501). At this time, the user specifies, for example, a time period in which the simulation result is to be confirmed.
Subsequently, 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 ST 502). Here, in the data processing apparatus 1, the simulation data constituted by one file is divided into a plurality of files under a predetermined division condition, and is recorded in association with the corresponding division parameters. Therefore, data corresponding to the division parameter specified by the user can be read instantaneously. This eliminates the need for a long-time reading process and a search process as in the conventional art, and increases the speed of the process. The reading process by the reading unit 202 can be temporarily stopped by a user operation, and when the reading of the data in the time zone designated by the user is not completed, the data in the time zone is read preferentially.
Subsequently, 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 ST 503).
Subsequently, the display data generating unit 204 generates display data using the three-dimensional moving image data generated by the three-dimensional moving image data generating unit 203 and at least the three-dimensional data of the device (step ST 504). In addition, in the case of a rolling plant, the three-dimensional data of the machine described above is the three-dimensional data of the box portion of the rolling mill 11.
Then, the display data is displayed on the display.
Next, data of a time period designated by the user is read out and processing to perform drawing is shown. Here, a case will be described as an example where a divided file relating to simulation data of the steel material 12 is read and plotted. In the display data generating device 2, the recording start time of each object recorded in the recording unit 103 of the data processing device 1 is examined in advance.
In this case, first, the reading unit 202 reads data at the first time of a 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 lattice point corresponding to the division pitch. The reading unit 202 also reads the temperature, the flatness, and the luminance value. When the time to read the target is less than the target recording start time, the reading process for the target is skipped.
Subsequently, the three-dimensional moving image data generation unit 203 creates data for polygon generation 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 numbers of the run numbers. Coordinate values (x, y, z) are assigned to the vertex numbers.
At this time, first, the distribution is started from the forward direction end in the width direction of the steel material 12 and the most forward coordinate value in the depth direction, and then the distribution is performed while shifting one by one in the depth direction. When the terminal end in the depth direction is reached, the cutting is performed while shifting the terminal end in the depth direction by one in the negative direction in the width direction and then shifting the terminal end in the depth direction in the same manner as described above.
The three-dimensional moving image data generation unit 203 generates a numerical value converted into color information in accordance with the display setting from the temperature, the flatness, and the luminance value based on the data read by the reading unit 202.
Since a polygon is composed of three vertices, each of the three vertices is numbered in order. The designated sequence refers to and selects the element number of the lattice point so that the order of connecting the vertices of the triangle is counterclockwise, and records the vertex number corresponding to the coordinate.
Further, the three-dimensional moving image data generation unit 203 generates two-dimensional expansion coordinate values for texture projection at the same time. In this case, one polygon of a triangle formed by three vertices and a polygon adjacent to the hypotenuse are collectively treated as a set of quadrangles, and the size of each square is maximized on a two-dimensional plane of the square whose one side is 1 in length.
Then, the processes of the reading unit 202 and the three-dimensional moving image data generation unit 203 are performed for the next time. By repeating the above-described processing, data can be read in a predetermined time period and various data can be created.
Thereafter, the display data generation unit 204 performs polygon rendering processing. If the generation of the data for generating the polygon in the predetermined time period is not completed, the generation of the data is executed before the polygon rendering processing. On the other hand, when data for polygon generation exists, polygon rendering processing is performed based on the data. In the display data generation unit 204, the painting process is not performed for the target space to which the steel material 12 has not yet arrived.
Next, an example of the display data generated by the display data generating unit 204 will be described.
Fig. 6 shows a part of a view for reproducing a moving image of rolling of the steel material 12. In fig. 6, in addition to the visualization of the rolling simulation which has been conventionally performed, a certain realistic expression is performed such as whether or not the steel material 12 heated to a high temperature is actually photographed.
In the case of reproducing the expression shown in fig. 6 by the conventional method, it is necessary to calculate the thermal energy for each lattice point of the steel material 12 from the simulation data, calculate the optical energy from the thermal energy, convert the optical energy into the drawing pixel, and perform drawing, 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 mill. Therefore, in the present invention, the reproduction is performed with the expression of the simulation with a low calculation load.
Specifically, in the data processing device 1, the brightness value of each grid point of the steel material 12 is assigned a numerical value exceeding 1 according to the temperature of each grid point. Then, in the three-dimensional moving image data generating unit 203, when performing three-dimensional rendering, a luminance value is assigned to a rendering pixel of the steel material 12, and when the value is equal to or greater than a certain value (for example, equal to or greater than 1.1), processing for expanding the color of the rendering pixel is performed. 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. In addition, the luminance of the painting pixel is generally expressed in a range from 0, which is black, to 1, which is white. Accordingly, the picture pixel having a value exceeding 1 is an intentionally specified portion, and does not have an appearance that other portions (for example, white portions of the rolling mill 11) are expanded and emit light.
In addition, conventionally, a high-performance simulation PC is used to perform three-dimensional display while being limited to one target space. Even in the three-dimensional display defined as above, much time (from half a day to one day) is required for the calculation in advance. In contrast, in the present invention, even with an inexpensive general-purpose PC, the data amount of one file on average of the read data is reduced, and therefore, the entire rolling facility as shown in fig. 6 can be easily displayed three-dimensionally.
In the present invention, the operation of confirming the simulation result is specialized and is configured independently of the simulation execution device. This makes it possible to limit the functions, provide easy operability for the user, and reduce the capability of the general-purpose PC on which the display data generating device 2 is mounted.
Note that the sub selection items included in the display content operation function portion 301 are displayed in the lower portion in the same manner only when various functions are selected. This can provide intuitive operability for the user, and prevent confusion associated with access to a target function. For example, fig. 7 shows a case where the photographing angle selecting section 3011 is an example of a sub selection item of the display content operation function section 301. The imaging angle selection unit 3011 can perform three-dimensional display viewed from a desired direction. Further, by operating the pointer, the user can freely change the direction of the image to an angle other than the fixed shooting angle.
In addition, the time operation function unit 302 can confirm the progress of the current reading process at a glance by coloring the area of the time zone in which the reading of the analog data is completed.
As described above, according to embodiment 1, the present invention includes: a data processing device 1 having an acquisition unit 101 for acquiring simulation data, a dividing unit 102 for dividing the simulation data acquired by the acquisition unit 101 into a plurality of files according to a dividing condition, and a recording unit 103 for recording the data divided into the plurality of files by the dividing unit 102 in association with a dividing parameter corresponding to the dividing condition; and a display data generating device 2 having a reading unit 202 for reading out data associated with the division parameter from the recording unit 103, a three-dimensional moving image data generating unit 203 for generating three-dimensional moving image data from the data read out by the reading unit 202, and a display data generating unit 204 for generating display data using the three-dimensional moving image data generated by the three-dimensional moving image data generating unit 203 and at least three-dimensional data of the device, so that it is possible to perform three-dimensional display while suppressing processing delay even with a general-purpose PC. As a result, it is possible to realize a three-dimensional display that can be effectively used for calling for technical explanation and technical effort and for calling customers in a conference room, a show, or the like, using simulation data used for analysis and verification.
In the above description, the case where the acquisition unit 101 acquires both the simulation data of the substance acted on by the machine and the simulation data of the position acted on by the substance and the position acted on by the substance in the machine is shown. However, the present invention is not limited to this, and only simulation data of a substance acted on by a machine may be acquired.
Fig. 8 is a diagram showing an example of the configuration of the 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 an example in which the blank data deleting unit 104 is added to the configuration example of the display system shown in fig. 1. Other configurations are the same, and the same reference numerals are used to describe only different portions.
The null data deleting unit 104 deletes null data from the file divided by the dividing unit 102.
The recording unit 103 records the data of the file divided into a plurality by the dividing unit 102 and the null data deleted by the null 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 does not reach is a portion where tension or the like is not generated, and normally, null data such as 0 is recorded. However, this null data is not needed for three-dimensional display. By deleting the dummy 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 device 2 can be speeded up.
Embodiment 3.
In embodiment 3, a case is shown in which data for animation display and data for detailed display (cross-sectional display) are separately recorded. Fig. 9 is a diagram showing an example of the configuration of the 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 an example in which the internal data deleting unit 105 is added to the configuration example of the display system shown in fig. 1. Other configurations are the same, and the same reference numerals are used to describe only different portions.
The internal data deleting unit 105 deletes the internal data from the file divided by the dividing unit 102. Here, the internal data is analog data relating to an unnecessary substance for displaying moving images and an internal part other than the surface of the device.
In addition to the data divided into a plurality of files by the dividing unit 102, the recording unit 103 records the data of the file from which the internal data has been deleted by the internal data deleting unit 105 in association with the division parameter.
In an animation display that displays only the appearance of a substance and the appearance of a machine, simulation data of the inside of the substance and the inside of the machine are not necessary. Then, the internal data is deleted. Further, data for animation display and data for other detailed display (section display of the steel material 12, the roller 111, and the like) are separately recorded. This can further reduce the amount of data for animation display, and can speed up the processing in the display data generation device 2.
In the above description, the case where the internal data deleting unit 105 is added to the display system according to embodiment 1 is described. However, the present invention is not limited to this, and the same effect can be obtained by adding the internal data deleting unit 105 to the display system according to embodiment 2.
Embodiment 4.
Fig. 10 is a diagram showing an example of the configuration of the 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 an example in which the second dividing unit 106 is added to the configuration example of the display system according to embodiment 1 shown in fig. 1. The other structures are the same, and the same reference numerals are used to omit descriptions thereof.
The second dividing unit 106 further divides the file divided by the dividing unit 102 into a plurality of files at the 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 at the division pitch in association with the division parameter.
In the present invention, the cross section of the steel material 12, the roll 111, and the like can be displayed. In this case, reading of data other than the cross section is unnecessary. Then, the file is further subdivided in accordance with the division pitch. This can further reduce the amount of data of one file on average recorded in the recording unit 103, and can speed up the processing in the display data generating device 2.
The data divided at the division pitch is not divided at each time Δ t from the start of simulation in the dividing unit 102. That is, data of all times when a substance exists at the place is recorded in a file divided at the division pitch. In the case of displaying the cross section, predetermined data (for example, data of 7 positions directly under the roller 111) among the data divided at the division pitch is read.
In the above description, the second division portion 106 is added to the display system according to embodiment 1. However, the present invention is not limited to this, and the second division unit 106 may be added to the display systems according to embodiments 2 and 3.
In the above description, the case of using simulation data for a rolling mill including a rolling mill 11 (machine) that rolls a steel material 12 (material) has been described as an example, but the present invention is not limited to this. For example, the present invention is also applicable to a case where three-dimensional display is performed using simulation data for an air conditioner (equipment) and air (material) flowing out of the air conditioner as warm air or cool air.
In the present invention, any component of the embodiment may be modified or omitted within the scope of the invention.
