[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computing system using the Internet, and more particularly, to a network capable of obtaining calculation results by inputting calculation conditions from a computer connected to the Internet to a server. Regarding services.

[0002]

2. Description of the Related Art In the technical calculation field, at the time of product concept design or early design, a design object is modeled into a simple shape, and is manually calculated by a calculator using a formula or the like.
Consider guidelines for design variables. It is also known that a simple calculation program or the like that supports official calculation is used. Based on these calculations, a guide to the design variables is grasped, and a transition to detailed design is made. Next, it is known that detailed modeling is performed by a CAE system, and calculation is performed by a calculation program represented by the finite element method. Each of these processes is a form in which a computer is used to perform a calculation process, and it is assumed that a calculation program is purchased.

[0003] In addition, a calculation service using the Internet is also known. By accessing a site where the calculation program can be used for free or for free on the Internet, calculation processing can be performed even if the user does not have the calculation program. Such calculation services are used in various fields such as profit and loss calculation of stock price information and calculation of environmental impact assessment.

[0004]

In a manual calculation by a calculator using a formula, there is a possibility that a long time is required for the calculation or a calculation error occurs, and the calculation efficiency and the reliability of the calculation result are impaired. In addition, programs that perform simple calculations in design are available on the market.
It takes time to upgrade the version.

Further, in order to use a CAE system or a calculation program typified by a finite element method analysis program, advanced utilization techniques and knowledge are required, and enormous time and cost are required to train skilled personnel.

The CAE system and the calculation program are expensive programs, and a high cost is required to introduce a license to all individual designers.

[0007] For this reason, attention has been paid to a mechanism for obtaining a program from the Internet as needed. As a result, an expensive calculation program can be used at a low cost.

In such a calculation service provided by the Internet, a calculation condition is input on a calculation condition input screen, and a calculation is executed by a calculation execution button. Then, a method is generally used in which a calculation is performed on the server side and a screen displaying the calculation result is displayed.

[0009] However, if a calculation requiring a long time to complete the calculation is performed by this method, the calculation may be interrupted due to a timeout of the session on the server side. In a large-scale calculation using an analysis program, it may take several hours to complete the calculation. Performing such a calculation requiring a long time until the end of the calculation cannot be realized by the above-described method.

[0010] Further, in order to make the system easy to use, means for storing and reusing calculation conditions and calculation results is also required. It is possible to develop a program that runs on a Web browser and save the calculation conditions and calculation results in a file. However, in the Internet environment, the operation of saving a file using such a program is a dangerous act from the viewpoint of security and has a problem. Further, performing the calculation processing only by the server has a problem that the load is concentrated.

An object of the present invention is to propose a calculation system having means for realizing a calculation that cannot be processed by a normal server in a calculation service available via the Internet.

It is another object of the present invention to provide a calculation system which can solve a problem such as interruption of calculation due to timeout of a session on a server side in a calculation service available via the Internet.

Another object of the present invention is to provide a calculation system that makes it impossible for a third party to view the calculation contents and the calculation results.

[0014]

Another object of the present invention is to provide a computer system which is connected to the Internet, displays a screen for inputting the type of calculation and its data on a user computer, and executes the calculation. In, when it is determined that the time required for the calculation takes a long time,
This is achieved by providing a function of transmitting the end of the calculation.

Another object of the present invention is to provide a computer which is connected to the Internet and allows a user computer to display a screen for inputting the type of calculation and its data. In the calculation system to be executed, when it is determined that the time required for the calculation requires a long time, the calculation result is achieved by providing a function of displaying a screen for allowing the user to select a transmission method on the user side computer.

In this case, the computer which performs the calculation process reads the result and displays a calculation result report. As a result, the user can obtain the calculation result without being conscious of the calculation program. Further, even when the calculation program exists in another computer, the calculation can be performed by the same processing.

According to the ninth aspect of the present invention, when it is determined that the calculation by the server-side computer requires a long time, the end of the calculation is transmitted to the user-side computer. Since the connection with the local computer is temporarily terminated, the situation such as interruption of the calculation due to timeout is eliminated.

According to the tenth aspect of the present invention, the user can select a method of transmitting the calculation result that suits the user, so that the possibility of the third party being informed of the calculation contents and the calculation result is reduced.

The calculation mediation program is used in the control unit 19, and transmits and receives data and executes the calculation program 23 in cooperation with the calculation control program read by the control unit 11 of the server 10. The storage means 23 stores a calculation program. A plurality of calculation programs may exist depending on the type of calculation, and are used in the control unit 19. The configuration of the calculation server 102 is the same.

Next, the operation of this embodiment will be described. Here, the terminals 103, 104, 105,... Are connected to the server 10 to perform communication. However, for convenience of explanation, the following description will be made assuming that the terminal 103 is connected to the server 10. In addition, each program stored in the storage unit of the server 10 and the calculation servers 101 and 102 is read by the control unit 11 or the control unit 19 to perform a process. For convenience of explanation, “... Is expressed as

When the terminal 103 is connected to the server 10, the control means 11 detects this connection via the input means 12, and controls the terminal 103 according to the calculation control program 14. FIGS. 4 and 5 are flowcharts showing the operation of the calculation control program.

First, in step Sa1 shown in FIG. 4, the calculation control program 14 displays a log-in screen for the system as shown in FIG. The user is prompted to enter a user name in field 201 and a password in input field 202. On the display unit of the terminal 103, a mouse cursor MC is displayed, and various operations can be performed by clicking a predetermined place. When the mouse cursor MC is positioned in the display area of the button 203 and a click operation is performed, the input user name and password are sent to the control unit 11. Then
When detecting this, the control means 11 determines whether or not the use registration has been made by the user authentication program 14.
Here, if the user name and password are not registered, the process proceeds to step Sa2, and the display unit of the terminal 103 displays
Displays an error message that prompts for the correct username and password. If the use registration has been made, the procedure proceeds to step Sa3, and the calculation control program 14
Thus, the display unit of the terminal 103 is controlled to display a calculation system menu screen as shown in FIG.
Thus, for convenience of description, performing a click operation with the mouse cursor positioned in the display area of the button is expressed as selecting the button with the mouse.

Now, on this calculation system menu screen, buttons 211 to 214 corresponding to the respective calculation processes of “structural calculation”, “vibration calculation”, “heat transfer calculation” and “fluid calculation” are shown, and the terminal operator is instructed. On the other hand, the user is prompted to select any desired processing. The terminal operator selects a button corresponding to an item for performing a desired calculation with a mouse.
Hereinafter, a case where “structural calculation” is selected will be described.
When the button 211 corresponding to “structural calculation” is selected with a mouse, the calculation control program 14 controls the display unit of the terminal 103 to display the screen shown in FIG. The selection of the item for which the target calculation is to be performed has a hierarchical structure, and the selection operation proceeds to finally reach the target calculation item. Here, the case where “beam calculation” is selected will be described. By selecting beam calculation button 215 with the mouse, the calculation type is determined to be “beam calculation” of “structural calculation”. The calculation control program 14 determines the type of calculation, displays a calculation condition input screen according to the type of calculation, and determines a calculation program to be used for calculation.

With this operation, the step proceeds to Sa4, and the calculation control program 14 controls the display unit of the terminal 103 to display a calculation condition input screen corresponding to the calculation type as shown in FIG. .

On the calculation condition input screen, an explanatory diagram 225 for explaining the symbol L indicating the dimension of the beam length in the input field 211 is displayed to clearly indicate what the symbol L indicating the beam length means. In this case, it is possible to reduce errors in inputting data to the input field. Input field 221
If the value of the moment of inertia to be input to the terminal 103 is unknown, the user selects button 226 with the mouse to
Is controlled to display the second moment of area calculation screen shown in FIG. Here, when the terminal operator selects a range of the figure corresponding to the target cross-sectional shape with a mouse, the calculation control program 14 displays a second moment of area calculation screen of the selected shape on the display unit of the terminal 103. To control. For example, when the area 227 is selected by a mouse, a calculation screen of a square cross section is displayed, and when the area 228 is selected by a mouse, a calculation screen of an ellipse cross section is displayed. As described above, the cross-sectional shape is displayed in a format that can be intuitively determined, and by selecting it, the operability is improved. After calculating the second moment of area, the terminal operator inputs the calculation conditions in the input field 221 and proceeds to step Sa5. When there are many calculation condition items to be input, the screen may be divided into a plurality of input screens, and input is performed by switching the screens. In step Sa5, if it is necessary to input material property information or the like when inputting the calculation conditions, the user proceeds to step Sa6 by selecting the property value search button 222 with a mouse, and performs a search using the calculation information database 18. FIG. 12 shows a search screen for the Young's modulus of the calculation information database. After inputting all the calculation conditions, the button 223 is selected with a mouse, and the process proceeds to Step Sa7. In step Sa5, when it is not necessary to search for calculation information, button 223 is selected with a mouse, and the process proceeds to step Sa7.

In step Sa7, the calculation control program 14 performs an operation of displaying the input information confirmation screen shown in FIG. 13 on the terminal 103, and prompts the terminal operator to confirm the input information from the input information list 231. The terminal operator checks whether the input information is correct. Next, the process proceeds to Step Sa8. In step Sa8, if there is a mistake in checking the input information, the terminal operator selects the button 232 for returning to the calculation condition input screen with the mouse. Upon detecting this, the calculation control program 14 returns to step Sa4, and controls the display unit of the terminal 103 to display the calculation condition input screen of FIG. 10 again. The terminal operator corrects the calculation conditions of the input field 221 and proceeds to step Sa7.
If there is no mistake in the input, the terminal operator selects the calculation execution button 234 with the mouse. The calculation control program 14 that has detected this proceeds to step Sb1 in FIG.

The processing of Sb1 to Sb9 described below is automatically processed by the calculation control program 14. Steps
In Sb1, it is determined whether or not the calculation requires time, depending on the type of calculation and the calculation condition. Here, the process of step Sb2 when it is determined that no time is required will be described. The processing in the case where time is required will be described later.

In step Sb2, the type of calculation is determined, and it is determined whether preprocessing of the calculation conditions is necessary. For example, preprocessing is required in the case of a calculation program using a finite element method that requires calculation input data obtained by processing calculation conditions. Here, a case of a calculation program using a finite element method that requires preprocessing will be described. If it is determined in step Sb2 that pre-processing is necessary, step Sb3
Proceed to. Here, a calculation model is created from the calculation conditions,
Perform automatic element division. Next, the process proceeds to step Sb4 to create calculation input data according to the input format of the calculation program. Next, the process proceeds to step Sb5. Step Sb5
Then, it is determined whether to request the calculation processing to the calculation server.
Here, the calculation program used for the calculation is the server 10
The process that proceeds to step Sb6 without requesting the calculation server to perform processing will be described on the assumption that the process exists in the calculation server. On the other hand, if the calculation program does not exist on the server 10, the calculation processing is requested to the calculation server. The procedure for requesting the calculation server to perform a calculation process will be described later.

In step Sb6, the calculation input data is passed to the calculation program 15, and the calculation is executed. Next, the process proceeds to step Sb7, where the calculation result of the calculation program 15 is read. Next, the process proceeds to step Sb8, where a report of the calculation result is created. Next, the process proceeds to step Sb9, where a report of the calculation result is displayed on the display unit of the terminal 103. The calculation result report displays calculation conditions and calculation results in a list format. If necessary, graphs, figures, and the like are displayed. Further, in the calculation of the three-dimensional model, the calculation result may be converted into three-dimensional display data to display the result. For three-dimensional display data, display is performed by dedicated software. FIG. 14 shows an example of the calculation result report display.

On the other hand, if it is determined in step Sb1 that the pre-processing is unnecessary, the process proceeds to step Sb10, where the calculation conditions are passed to the calculation program 15 and the calculation is executed. Subsequent processing from step Sb7 to step Sb9 is the same as the above-described processing.

Next, a procedure for requesting a calculation server to perform a calculation process in step Sb5 will be described. The calculation control program 14 requests the calculation server to perform the calculation processing when the target calculation program does not exist in the server 10 or when the load of the server 10 is distributed, and the control information is registered in the calculation control program 14. Have been. If it is determined in step Sb5 that the calculation server is requested to perform the calculation process, a calculation server to request the calculation is determined based on the control information registered in the calculation control program 14, and the process proceeds to step Sb11. Here, for convenience of explanation,
The following description is based on the assumption that the calculation server 101 has been determined. In step Sb11, the calculation control program 14 cooperates with the calculation mediation program 22 of the calculation server 101 via the local area network LAN, and
The calculation input data is transmitted from the output control means 13 to the input control means 20 of the calculation server 101. The calculation mediation program 22 temporarily stores the received calculation input data, and proceeds to step Sb12. Step Sb1
In 2, the calculation control program 14 requests the calculation mediation program 22 to execute the calculation. The calculation mediation program 22 that has received the request transfers the calculation input data to the calculation program 23, executes the calculation, and proceeds to step Sb13.
In step Sb13, the calculation control program 14 executes the calculation mediation program 22 and the local area network LA
Output control means 2 of the calculation server 101 in cooperation with each other
1 to the input control means 12 of the server 10 to receive calculation result data. The calculation control program 14 temporarily stores the received calculation result data, and proceeds to step Sb7.
Proceed to. Thereafter, the same processing as described above is performed.

Next, storage of calculation conditions and calculation results will be described. When designing a product, calculation conditions are changed little by little and recalculation is performed, and a parameter survey for finding optimal design variables is performed. When there are many input items of the calculation condition, it is troublesome to re-input the calculation condition. In addition, in order to perform a calculation by correcting a previously performed calculation condition, it is necessary to save the input calculation condition. Further, by storing the calculation result, it is possible to redisplay the calculation result that was previously executed without performing the calculation again.

In order to save the calculation conditions, the save calculation condition button 233 in FIG. 13 is selected with a mouse. This allows
The calculation condition storage screen shown in FIG. 15 is displayed on the display unit of the terminal 103. In the scrollable text area 241, items of calculation conditions are displayed in a text format. This text data can be stored in the storage area of the terminal 103 by cut-and-paste by the terminal operator.

When performing calculations with the calculation conditions modified,
The item of the saved text data is corrected with a text editor or the like, and the calculation condition text input button 223 in FIG. 10 is selected with a mouse. Thus, the calculation condition text input screen shown in FIG. 16 is displayed on the display unit of the terminal 103.
Next, the corrected text data is stored in the text area 251.
When the user clicks the execute button 252 with the mouse, the calculation conditions are input to the system, and the input information confirmation screen of FIG. 13 is displayed on the display unit of the terminal 103. Subsequently, the calculation can be executed by selecting the calculation execution button 234 with a mouse.

The calculation results are also displayed on the display unit of the terminal 103 in a dedicated format in a text format on a screen similar to that shown in FIG. 15, so that the calculation result data can be stored. The saved calculation result data is cut and pasted into the text area on the same screen as in FIG.
By selecting the execution button with the mouse, a report of the calculation result can be displayed.

What has been described above provides means for storing the calculation conditions and calculation results input by the user. Thus, in calculating many input items of the calculation conditions, the text file in which the calculation conditions are stored is corrected by a text editor or the like, so that the same calculation can be efficiently executed without inputting again on the calculation condition input screen. It is possible. This is effective for a parameter survey in which the calculation is repeated while changing the calculation conditions little by little to find the optimal design variable. In addition, by storing the calculation results, it is possible to easily call back the past calculation results, and there is an advantage that comparison and comparison of the calculation results can be easily performed.

Next, a case where it is determined in step Sb1 that it takes time to complete the calculation will be described. The processing time required for calculation differs depending on the calculation program used. Further, in a calculation program such as a finite element method, the calculation load increases as the number of element divisions of the calculation model increases. Further, the processing time differs depending on the processing capacity of the calculation server. Therefore, the calculation control program 14 stores a factor for the processing capacity of the calculation server, a factor for the processing time depending on the type of the calculation program, and a table for calculating the factor for the calculation load from the number of element divisions of the calculation model. The time required for the calculation is calculated by multiplying the factors, and if the calculated time exceeds the time-out period of the session, it is determined that it takes time to complete the calculation. This prevents calculation from being interrupted due to a session timeout.

In the above processing, when it is determined that it takes time to complete the calculation, the calculation control program 14 accepts the calculation, performs the calculation in the background, and notifies the terminal operator of the end of the calculation after the calculation is completed. Means and means for displaying the calculation result are provided to the terminal operator.

As means for displaying the calculation result, the following 3
Offers one. The first is "Issue a calculation ID immediately." This can be inquired of the calculation state by the calculation identification ID, and is effective when the terminal operator keeps using the terminal. The second is "identification of calculation
Issuing ID by email ". This means that the end of the calculation can be known by the arrival of the mail, and the identification ID of the calculation
It is possible to display the calculation result. The third is "Deliver the calculation result URL by e-mail". In this case as well, the end of the calculation can be known by the arrival of the mail, and the calculation result can be displayed by specifying the address (URL) of the calculation result in the Web browser.

As described above, from the viewpoint of the terminal operator, there is no need to wait in front of the computer for the completion of the calculation, and it is confirmed by the calculation-specific identification ID or mail whether the calculation has been completed in a vacant time. can do. Also,
It is also possible to execute a plurality of calculations at once and display the results collectively later.

If it is determined in step Sb1 that the calculation requires time, the process proceeds to step Sc1 in FIG. If “Issue a calculation ID immediately” is selected in step Sc1, the process proceeds to step Sc2, and a calculation status confirmation screen as shown in FIG. Identification of calculation
The ID is displayed in the input field 261. The calculation identification ID is automatically determined by the calculation control program 14. When calculation status confirmation button 262 is selected with a mouse, the calculation ID specified in input field 261 is passed to calculation control program 14. Identification of the specified calculation
If the calculation performed by the ID is in the middle of calculation, a screen describing a message indicating that the calculation is being performed is displayed on the display unit of terminal 103. If the calculation is completed, a calculation result report screen is displayed on the display unit of the terminal 103.

Next, if "delivery of calculation ID by e-mail" is selected in step Sc1, the flow advances to step Sc3.
A screen for prompting the user to input a mail address as shown in FIG. The terminal operator inputs the mail address of the terminal operator into the input field 271,
The execute button 272 is selected with a mouse. After the calculation is completed, the calculation control program 14 gives the terminal operator the identification ID of the calculation.
And send an email with The terminal operator can know the end of the calculation by receiving the mail. The terminal operator displays the calculation status confirmation screen of FIG. 17, inputs the identification ID of the calculation in the input field, and selects the calculation status confirmation button 262 with a mouse, so that the calculation result report is displayed on the display unit of the terminal 103. Can be displayed.

Next, if "delivery of URL of calculation result by e-mail" is selected in step Sc1, the process proceeds to step Sc3,
A screen for prompting the user to input a mail address as shown in FIG. The terminal operator inputs the mail address of the terminal operator into the input field 271,
The execute button 272 is selected with a mouse. After the calculation is completed, the calculation control program 14 displays the address (UR) of the calculation result page for displaying the calculation result report to the terminal operator.
Send an email with L). Identification of the address of the calculation result page to display the calculation result of the terminal operator
ID is included. The terminal operator can know the end of the calculation by receiving the mail. The terminal operator can display a calculation result report on the display unit of the terminal 103 by accessing using the address of the calculation result page.

Further, the terminal operator can display the list of identification IDs of the calculations performed by the terminal operator on the display unit of the terminal 103 by executing the list of calculation IDs. The identification ID of the calculation performed by the terminal operator can be specified from the user name / password input by the terminal operator. The calculation identification ID list displays the calculation status such as “calculation in progress” and “calculation end” together with the identification ID of the calculation. The terminal operator can display the calculation result report on the display unit of the terminal 103 by selecting the identification ID of the calculation displayed as “end of calculation”.

The calculation result data is sent to the server 10.
The data can be stored in two ways, and the terminal operator can make a selection. The first is a method of storing data with a time limit. The calculation result data that has passed the predetermined time limit is automatically deleted by the calculation control program 14. 2
The third is a method in which an upper limit of a storage area is determined for each terminal operator, and data can be stored within the range regardless of a time limit. The terminal user can apply for the upper limit of the storage area. The terminal operator is charged according to the size of the area. The calculation result data is stored together with various information such as a calculation identification ID, a result storage date and time, and a comment. By executing the calculation result storage data list, the terminal operator can display a list of calculation results stored by the terminal operator on the display unit of the terminal 103 together with various information. The terminal operator can display the saved calculation result by selecting the target calculation result. Unnecessary calculation results can be deleted using a list.
