Description

  The present invention relates to a parameter setting support apparatus for setting parameters in a simulator, a control method thereof, and a program, and more particularly to a parameter setting support apparatus and the like suitable for efficiently changing and setting parameter values.

  In recent years, with the improvement of computer performance, CAD used in machine design work is rapidly shifting from two-dimensional CAD to three-dimensional CAD. Also, in order to shorten the development period and man-hours, design verification is being performed using a simulator utilizing three-dimensional data before actual machine verification. In addition, machine durability tests prior to the start of mass production, such as copying machines, set parameters in consideration of the results of durability tests such as roller wear and electromagnetic clutch connection delay, and verify the design on the simulator. Efforts are being made.

  When performing the simulation, the user sets parameters (parameter values) necessary for the simulation such as material, friction, density, Young's modulus, force, heat quantity, air volume, and voltage to the simulator, and constrains the mechanism and contact surface. Conditions are given, and the simulator divides necessary parts such as a mechanism part and a contact surface into a mesh or the like as necessary, solves an equation, and calculates a simulation result.

  In addition, since the validity of the parameter value has a great influence on the simulation result, the parameter value is accurately obtained by repeating the experiment, and further, the parameter value database is being developed so that it can be used in various simulators.

  Also, recent simulators such as mechanism analysis software provide a mechanism for setting parameter values by reading parameter files and setting parameter values, assuming parameter exchange with the outside. The operability may be improved.

  Further, there is a document describing a method for efficiently managing a combination of a large amount of input data (see Patent Document 1). However, in Patent Document 1, parameter input is closed in the system, and an external It doesn't mention the cooperation with the database. There is no document describing the method of generating input data.

  Furthermore, efforts have been made to efficiently set parameters by calculating variation parameters using a predetermined interpolation function. For example, regarding a method for changing parameter values at the time of designing a semiconductor, a mechanism has been proposed in which parameter values can be set efficiently using an interpolation function (see Patent Document 2).

In addition, the optimal parameter values obtained by the wiper analysis simulator are output once to an intermediate file, passed to the spreadsheet software, and then linked to the 3D CAD while checking the parameter values on the spreadsheet software. Attempts are being made to model, that is, to create a template for the design.

  However, there are still many points to be solved in order to verify the effectiveness on the simulation without making an actual machine. In addition, at present, it cannot be said that the simulation with durability is efficiently performed from the created design data.

  For example, even if a result according to the design specification is obtained in the simulation in the case where the design value is set, the result as the simulation may not be obtained when actually operating with the actual machine. As one of the factors, a tolerance existing in each part of the machine can be considered, and it is necessary to perform a simulation in consideration of these tolerances.

  Based on the design drawing received from the design department, in order to perform accurate simulation with a combination of several parameter values that take into account the tolerance of parts in the verification department, It is necessary to read various information. In addition, since it takes a long time to read various information such as tolerances from the design drawing, it may be possible to set a parameter value that takes into account the tolerance in the design department, but in this case, parameter setting Since an unskilled person in the design department sets a large amount of parameter values, there is a possibility that the parameter values may be omitted.

  In addition, data other than tolerances, for example, data of each part after the durability test is often managed not by the design department but by a department (for example, a quality assurance department) that actually performs the durability test. In this case, a person in the verification department or the design department that performs the simulation needs to obtain data from a department such as the quality assurance department.

  As described above, various parameters necessary for the simulation are scattered in a plurality of departments. However, conventionally, a mechanism for efficiently exchanging these parameters between departments has not been established.

  In general, simulator software has a function of outputting a parameter file as an external file. However, the format of the parameter file is not uniform between the simulator software or its production companies, and the file data However, it was difficult to understand what was written, and it was necessary to understand it using the output format specification.

  The present invention has been made to solve such a problem, and an object of the present invention is to make it possible to efficiently change and set parameter values when performing simulation while changing parameter values. The object is to provide a setting support apparatus, a control method thereof, and a program.

A parameter setting support apparatus according to the present invention includes a reading unit that reads a parameter file output from a simulator for verifying a design of a machine having components used in a plurality of use conditions, and a parameter file that is read by the reading unit Display means for displaying the parameter values of the parameters in a table in a predetermined format, designation means for designating the parameter values displayed in the table based on user instructions, and changing the parameter values designated by the designation means A change means, a database storing the maximum and minimum values of the parameter values for each of the plurality of use conditions for each of the parts with respect to the parameters, and displayed in the table after the change processing by the change means Output parameter values in a file format that can be processed by the simulator. And an output means for said change means, when the setting of the maximum value or the minimum value of the parameter value for the parameter is instructed by the user, the maximum value of the parameter values in the finger indicated parameters from the database or get the minimum value, and changes the maximum value or the minimum value of the parameter values for the finger indicated parameters to the maximum or minimum value of the acquired parameter values.

  According to the present invention, it is possible to provide a parameter setting support device, a control method thereof, and a program capable of efficiently changing and setting parameter values when performing simulation while changing parameter values. Become.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

[Device configuration]
FIG. 2 is a block diagram showing a schematic configuration of the parameter setting support apparatus according to the embodiment of the present invention. In FIG. 2, 17 is a central processing unit (CPU), 18 is a display device, 19 is an input device, and 20 is a storage device. The central processing unit (CPU) 17 performs various processes such as a parameter change process in response to an instruction from the input device 19. The input device 19 includes a pointing device such as a keyboard and a mouse, and can input commands and data necessary for parameter change, a menu selection instruction, and the like.

  The display device (display) 18 has a three-dimensional shape, a parameter display model (not shown), a parameter table 41 (see FIG. 6 etc.), and input data (various parameters) according to the processing of the central processing unit (CPU) 17. Etc. are displayed. The storage device 20 is configured by all or a part of various memories such as a ROM (Read Only Memory), a RAM (Random Access Memory), and an HDD (Hard Disk Drive).

  The HDD (hard disk drive) includes a system program (OS), an application program (input / output program shown in FIGS. 1 and 5) and a simulator 45 (see FIG. 4). The IF program 42 (see FIG. 4), a database (not shown), the parameter display model, and the like are stored in advance. The HDD also stores parameter files 43 and 44 (before and after parameter change), which will be described later. The ROM stores a boot program, font data, and the like in advance, and the RAM is used as a work area.

  In this parameter setting support device, a printer (not shown) that outputs information displayed on the display device 18 to paper may be connected to the central processing unit 17 and other peripheral devices may be connected as necessary. May be. Further, the parameter setting support device does not have to be a dedicated device, and can be configured by a general computer system such as a personal computer.

  Under such a configuration, the central processing unit 17 displays the parameter file output from the simulator on the display device 18 in a predetermined table format, and changes the parameter value using the input device 19 on the display screen. Then, a series of parameter changing processes of outputting the changed parameter file to the storage device 20 in a file format corresponding to the simulator is managed.

  Next, an outline of the operation of the parameter setting support apparatus will be described with reference to the flowchart of FIG.

  First, the central processing unit 17 reads the parameter file (see FIG. 3) output from the simulator (see FIG. 4) from the HDD into the RAM (step S1). Next, the central processing unit 17 analyzes the contents of the parameter file, and assigns a variable to the parameter name and its value so that it can be processed in the parameter setting support device (step S2). Thereafter, the central processing unit 17 displays the parameter name and its value on the display device 18 as a parameter table in a predetermined table format (step S3).

  The user changes the parameter value to be changed in the parameter table displayed on the display device 18 by using the input device 19 (step S4). For example, when examining the influence of the roller wear rate on the overall paper transport operation in verifying the paper transport variation, the cell related to the parameter of the roller radius on the parameter table is activated, and the parameter value of the roller radius is set. change.

  Next, the central processing unit 17 files the parameters (parameter names, parameter values) on the parameter table after the change processing in a file format (format, data format) corresponding to the simulator of the output source (step S5). The data is output to the HDD (step S6).

[Example of parameter file]
FIG. 3 exemplifies a parameter file output from the simulator. The parameter file has a unique file format (file format) by a commercially available simulator. For example, the parameter file shown in FIG. 3 is a parameter file output by the paper conveyance simulator, and various parameters relating to items such as the name of the roller, the conveyance efficiency (slip rate), the radius, and the rotation speed are in a predetermined format. (Data format).

[Cooperation between simulator and parameter setting support device]
FIG. 4 shows a data flow when the simulator and the parameter setting support apparatus cooperate through a parameter file. Here, the simulator 45 is assumed to be a simulator for performing design verification of the copying machine.

  The simulator 45 outputs to the HDD of the storage device 20 a parameter file 43 in which parameters defined by the simulator 45 are collected into one file. The IF program 42 (IF means an interface) analyzes the contents of the parameter file 43 output from the simulator 45 to the HDD, and a parameter table 41 in a predetermined table format (table format) as shown in FIG. Is generated and displayed on the display device 18. The parameter table 41 is used to check and change many parameter names and their values set in the simulator 45 at a time without looking at the property window.

  Since the parameter file 43 output from the simulator 45 is normally described in a text format as shown in FIG. 3, it can be analyzed, but it takes time to find a parameter to be changed. Therefore, in the present embodiment, a parameter name, its value, etc. are displayed in a table format so that a desired parameter can be found quickly. The parameter table 41 will be described later in detail.

  After the parameter value is changed on the parameter table 41, the IF program 42 creates a parameter file 44 in which the parameter name and its value of the parameter table 41 are filed in a file format that can be processed by the simulator 45 of the output source. Output to HDD.

[Detailed processing procedure in parameter setting support device]
Next, a detailed processing procedure of the parameter setting support apparatus will be described based on the flowchart of FIG.

  First, the central processing unit 17 displays various parameter display models, that is, various models of the parameter table 41 on the display device 18, and allows the user to select the parameter table 41 of a desired model (step S51). These models of the parameter table 41 are such that some parameters extracted from a large number of parameters stored in the parameter file 43 output from the simulator 45 are displayed in a table format. The model of the parameter table 41 corresponds to each department such as the design department, the verification department, and the quality control department, for example. In the parameter table 41 of the model corresponding to a certain department, the parameter value is changed in the department. Parameters that are unlikely to perform are excluded.

  In the model of the parameter table 41, the position (row, column) where various buttons such as “parameter file read button” and the extracted parameters (paper size, motor speed, radius, conveyance rate, etc.) are displayed. , Title) and the like.

  Next, when the user selects a desired model in the parameter table 41, specifies the parameter file 43 output from the simulator 45 on the parameter table 41 related to the selection, and presses the “parameter file read button”, The central processing unit 17 reads the designated parameter file 43 from the HDD into the RAM. (Step S52).

  Next, the central processing unit 17 analyzes the contents of the parameter file 43 related to reading by executing the IF program 42 (step S53), and only the parameter values of the parameters displayed in the parameter table 41 related to selection are displayed. Is extracted from the parameter file 43 for reading and displayed in the parameter table 41 (step S54). In this way, by narrowing down the parameter values to be displayed, it is possible to easily find the parameter value to be changed, and it is possible to quickly proceed with the parameter value changing operation.

  The user instructs a parameter value to be changed on the displayed parameter table 41 (step S55). This instruction is performed by designating the column displaying the parameter value to be changed by the input device 19. In this case, the designated column is highlighted in red or the like by the IF program 42.

  Next, the user changes the parameter value by specifying the parameter value changing method using the input device 19 (step S56). As this change method, there are “arbitrary designation change”, “maximum value / minimum value change”, “calculation formula change”, and “interpolation function change”. Specify the change method by pressing. Note that changing the maximum value and the minimum value means changing the tolerance.

  The above-mentioned “arbitrary change” is a method of actually inputting a parameter value, and “maximum value / minimum value change” is a database by pressing a button in order to save the trouble of checking a past database each time. This is a method of automatically inputting the maximum value or the minimum value in cooperation with the system. Also, “change calculation formula” automatically changes other parameter values so as to maintain consistency using a calculation formula when one parameter value is changed for a group of parameters related to each other. “Interpolation function change” is a method of changing parameter values at random using, for example, a wear interpolation function derived from past experiments. These changing methods will be described later in detail.

  Next, the central processing unit 17 changes the display form of the parameter value changed in step S56 to a special display form by the IF program 42 (step S57). That is, when there are many parameter values to be changed, which parameter value is the original design value (standard value, parameter value that has not been changed) and what change has been made to which parameter value As a result, the parameter value changing operation cannot be performed smoothly. Therefore, in the present embodiment, for example, the parameter value is input as black if it is a standard value, red if it is changed to the maximum value, blue if it is changed to the minimum value, and an arbitrary specified value. In such a case, the changed parameter value is displayed in a color corresponding to the change method, such as green in the case of change, yellow in the case of change by the calculation formula, and bluish green in the case of change by the interpolation function.

  When the parameter value changing operation is completed, the user designates a folder for outputting the changed parameter file, and presses the “parameter file output” button on the displayed parameter table 41 (step S58). In response to this button operation, the central processing unit 17 uses the IF program 42 to parameterize the parameter names and values of the parameter table 41 being displayed in a file format that can be processed by the simulator 45 of the output source. 44 is created (step S59) and stored in a folder according to the designation on the HDD (step S60).

  The simulator 45 can perform a simulation with the parameter value related to the change by importing the parameter file 44. When there are a large number of parameter files 44 in which parameter values have been changed, the simulator 45 imports the large number of parameter files 44 all at once or sequentially and repeats the simulation to thereby improve the efficiency. It is possible to perform simulation well.

[Detailed description of parameter table]
Next, the parameter table 41 will be described in detail with reference to FIGS. In the parameter table 41, as shown in FIG. 6, the parameter value to be changed can be quickly displayed by dividing a plurality of parameters relating to the parts such as a paper model, a motor, and a roller and displaying them together. And I am trying to find it without omission.

  In the parameter table 41 shown in FIG. 6, as the parameters relating to the paper model, three parameters of the paper model name, the vertical length, and the horizontal length (unit: mm) are collectively displayed. The lengths of the first and second sheets can be changed in units of 1 mm without omission. Also, as the parameters relating to the rollers, four parameters of the roller name, material, radius, and conveyance rate are collectively displayed. For example, when a simulation with a worn roller is desired, the parameter value of the conveyance rate is reduced. Or the radius parameter value can be reduced. Further, as parameters relating to the motor, parameters such as paper speed (mm / s), motor speed (rpm), motor settling constant (msec) and the like are collectively displayed. In the case of a stepped motor, the parameter values to be changed for each motor can be found quickly and without omission by displaying the parameters divided into a plurality of lines in the same column for each motor.

  In the parameter table 41, various function buttons are arranged as shown in FIG. The “parameter file read” button 71 shown in FIG. 7 is a button for instructing reading of the parameter file 43 output from the simulator 45, and the “parameter file output” button 72 is a parameter table 41 that has been subjected to parameter value change processing. This is a button for instructing output of the parameter file 44 according to the above.

  As will be described later, the “motor speed calculation” button 73 calculates a motor speed corresponding to the paper speed by a predetermined calculation formula when the user changes the parameter value of the paper speed on the parameter table 41, for example. This is a button for automatically overwriting the corresponding cell of the parameter table 41 with the motor speed. As will be described later, the “paper speed calculation” button 75 calculates a paper speed corresponding to the motor speed by a predetermined calculation formula when the user changes the parameter value of the motor speed on the parameter table 41, for example. This is a button for automatically overwriting the corresponding cell of the parameter table 41 with the paper speed.

  The “maximum value reflection” button 74 is a button for automatically searching and setting the maximum value or the minimum value of the parameter relating to the designation on the database. Thus, by automatically setting the maximum value or the minimum value using the database, it becomes possible to set the maximum value or the minimum value quickly and accurately.

  When a database is used, for example, parameter values such as part tolerance data managed by the design department and durability test data managed by the quality assurance management department are integrated into one database and managed centrally. By doing so, it is possible to efficiently exchange parameter values between departments, and further, it is possible to proceed quickly and accurately to change parameter values.

  The “all reset” button 77 is a button for resetting all currently displayed parameter values to “0”, and the “reflect standard value” button 78 is a button for resetting the value of a parameter related to designation to “0”. Further, the “reflect all standard values” button 79 is a button for changing all displayed parameter values to “standard values”, and the “change interpolation function” button 80 is a parameter value using an interpolation function as described above. This button is used to change the value at random. In addition, the code | symbol 81 shown in FIG. 7 has shown the state highlighted, such as the frame of the cell designated by the user being displayed thickly, or blinking.

[Change by calculation formula]
The significance of providing the “motor speed calculation” button 73 and the “paper speed calculation” button 75 is as follows. That is, some parameters are independent (such as paper size) and some are related to each other. For example, the paper speed (paper transport speed) varies depending on the radius of the transport roller, the gear ratio, the motor speed, the transport efficiency (slip rate), etc., and the relational expression shown in FIG. 8 is established. Therefore, for example, when the transport efficiency is changed, it is necessary to change the paper speed that changes accordingly. In such a case, if the user's confidence calculates and resets the paper speed, a great amount of labor is required, and there is a possibility that consistency between the conveyance efficiency and the paper speed cannot be obtained due to a calculation error.

  However, as described above, when the value of a certain parameter is changed by the user, the appropriate value of other parameter (or a plurality of parameters) related to the parameter is automatically calculated and set again. As a result, it is possible to reset the parameter values related to the parameters changed by the user quickly and without omission in a form that maintains consistency. Note that the parameter table 41 related to another model is provided with a calculation button for instructing another calculation. In addition, it is possible to obtain the same effect by using a lookup table storing corresponding parameter values for parameters related to each other without using a calculation formula. In this case, however, the memory capacity becomes enormous. .

[Change by interpolation function]
As shown in FIG. 9, by using the “change interpolation function” button 80, the values of the parameters related to the designation are changed randomly, and thousands of kinds of parameter files 44 related to various combinations of parameter values are obtained. Can be created easily and quickly.

  Regarding the value of each parameter, the maximum value and the minimum value are stored in the database (see FIG. 11), but when the intermediate parameter value is also stored in the database (or lookup table), as described above The memory capacity becomes enormous. Therefore, in the present embodiment, parameter values between the maximum value and the minimum value are automatically generated using an interpolation function. The method of changing the intermediate parameter value with respect to the maximum value and the minimum value differs depending on the parameter characteristics. For example, there are various changes such as “sine curve type”, “average type”, “proportional type”, and “discrete type” shown in FIG.

  Therefore, in the present embodiment, an interpolation function corresponding to how the intermediate parameter value changes with respect to the maximum value and the minimum value is stored in the database in association with each parameter, and “interpolation” is performed with the parameter specified. When the “change function” button 80 is pressed, the central processing unit 17 reads, from the database, the maximum value and the minimum value of the parameter relating to the designation and the interpolation function corresponding to the parameter relating to the designation by the IF program 42, The read maximum value and minimum value are given to the read interpolation function to calculate intermediate parameter values for the maximum and minimum values, and a parameter file is created and output for each calculated intermediate parameter value. . In this case, the number of intermediate parameter values to be calculated can be specified in the input area located on the “change interpolation function” button 80.

  With this configuration, for example, when a simulation of an endurance test is performed, it is possible to efficiently provide parameter values according to the way of wear of parts to the simulator 45 in a form close to an actual machine.

[Maximum and minimum values in the database]
As shown in FIG. 11, the database storing the maximum value and the minimum value of each parameter stores the maximum value and the minimum value of various parameters related to the component for each component, for example. When the parameter is designated and the “reflect maximum value” button 74 or the “reflect minimum value” button 76 is pressed, the maximum value or the minimum value of the specified parameter can be quickly searched.

  Also, as shown in FIG. 12, for example, even if a roller is used under the same conditions, the wear rate of the roller varies depending on the material. Further, when the roller is worn, the diameter of the roller gradually decreases. Therefore, when the wear rate of the roller differs depending on the material, even when the durability test is performed under the same conditions, it is necessary to set different maximum and minimum values (tolerances) of the roller diameter depending on the material of the roller. Therefore, in the present embodiment, for a predetermined part such as a roller, a material database storing a maximum value and a minimum value under each use condition is separately prepared for each material, and the material is displayed on the parameter table 41 being displayed. When specified and instructed to set the maximum and minimum values, the maximum and minimum values are obtained by accessing the material database.

[Optional change]
This is performed by an operation in which a user directly inputs and changes a parameter displayed on the parameter table 41.

  As described above, in this embodiment, the parameter value of the parameter file output from the simulator is displayed in a parameter table in a predetermined table format, and button operations such as a calculation button and an interpolation function change button on the parameter table are displayed. The function to change parameter values automatically, the function to display the changed parameter values in a color corresponding to the changing method (the above buttons, etc.), the function to change parameter values in cooperation with the database, etc. The parameter value in the parameter table after the change process is output in a file format that can be processed by the simulator of the output source. Changes, management, and settings can be performed.

  The present invention is not limited to the above-described embodiment. For example, the parameter setting support device and the simulator are configured by separate computers, and the parameter file between the parameter setting support device and the simulator is The exchange can be performed via a portable storage medium such as a floppy (registered trademark) disk, or via a communication line such as a LAN.

  Moreover, since commercially available simulators usually have a function of outputting parameter files to the outside, they can be directly applied to these commercially available simulators simply by preparing an IF program corresponding to these commercially available simulators. . In addition, the parameter values after the change are displayed in a visual identification form other than color, for example, an identification form by font, an identification form by a difference in halftone pattern in a shaded display, and an identification form by a difference in blinking pattern in a blinking display It is also possible to do.

  Furthermore, an object of the present invention is to supply a storage medium (or recording medium) in which a program code of software that realizes the functions of the above-described embodiments is recorded to a system or apparatus, and to perform computer (or CPU or MPU) of the system or apparatus. Needless to say, this is also achieved by reading and executing the program code stored in the storage medium. In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.

  Further, by executing the program code read by the computer, not only the functions of the embodiments described above are realized, but also an operating system (OS) running on the computer based on the instruction of the program code, etc. However, it is needless to say that a case where the function of the above-described embodiment is realized by performing part or all of the actual processing and the processing is included.

  Further, after the program code read from the storage medium is written in a memory provided in a function expansion card provided in the computer or a function expansion unit connected to the computer, the function expansion card or It goes without saying that a case where the CPU or the like provided in the function expansion unit performs part or all of the actual processing and the functions of the above-described embodiments are realized by the processing. When the present invention is applied to the storage medium, the storage medium stores program codes corresponding to the flowcharts (shown in FIGS. 1 and 5) described above.
