Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a WWW data server device for accessing component information stored in a database using a WWW (World Wide Web), and more particularly to an improvement in a method of displaying component information.

[0002]

2. Description of the Related Art In recent years, electric appliances such as home electric appliances have become very complicated, incorporating many functions. When assembling and manufacturing such electrical appliances, thousands to tens of thousands of parts must be manufactured based on design drawings. In the process up to the final product, each part is assembled into a parent part, and a larger part is assembled from such a parent part.

[0003] In an electric appliance maker, a large number of technical departments cooperate with each other to carry out everything from design to manufacturing, quality control, and after-sales care after sales. I'm communicating. Conventionally,
Such technical information is handed over on a paper basis, and the technical management department has to make a large number of copies every day, sort and distribute these copies. Also,
The technical department that received the copy also secured a place to store the ever-increasing number of technical documents and continued to struggle with version control.

[0004] On the other hand, attempts have been made to solve the problem by converting the technical document into an electronic file. That is, the technical document is converted into an electronic file, stored in a database, and accessed from a terminal installed in each department via a network. In particular, recent WWW (Worl
With the rapid development and spread of the d Wide Web, techniques for searching the database using the WWW are spreading. For example, a WWW server device has a function of executing a gateway script, and the WWW client device can cause the WWW server device to search a database using the function. Therefore, if the technical document is stored in the database of the WWW server device, the above-mentioned problem can be solved.

[0005]

SUMMARY OF THE INVENTION However, WWW
When referring to a technical document from a client device, when a keyword for issuing a query to a database is input, a current display method of displaying a list of data including the keyword is used in displaying the technical information as described above. It must be said that it is inadequate. For example, if the design of a part is changed for reasons such as cost reduction, even if it is necessary to know how the change affects a product or another part, a large number of various data including the part name are simply listed. It is difficult to predict the impact of a design change just by doing so.

[0006] Further, the design change of a component also affects a component that is not displayed even if a database is searched using the component name of the component whose design is changed as a key, such as a child component of a child component of the component. In many cases, there is a problem that the search must be repeated using the component name of the related component found in the first search as a key. The present invention relates to a WW for accessing, via WWW, a database storing technical information on a product composed of a number of parts.
It is an object of the present invention to provide a W data server device that displays data including the relationship between parts, in particular.

[0007]

In order to achieve the above object, a WWW data server apparatus of the present invention stores data including information on each component and configuration information indicating a parent-child relationship between the components. A database that has a database and is connected to a WWW client device via a network.
A WWW data server device, a display request receiving unit for receiving a display request for data stored in the database from a WWW client device, and a data extracting unit for receiving the display request and extracting data stored in the database; Using the configuration information, first display information for displaying, on the WWW client device, a tree in which the information of the parent part is arranged on the root side of the tree and the information of the child part is arranged on the branch side of the tree, using the configuration information. And a display information sending unit that sends the first display information to the WWW client device. By doing so, the parent-child relationship of the parts becomes clear at a glance, and it is easy to grasp which parts are affected by a design change or the like of a specific part. In particular, when it is desired to consider the reduction of the number of parts for cost reduction or the like, the child parts and grandchild parts can be overlooked.

The first display information created by the first display information creating means is a tree in which information of a parent part is arranged on the root side of the tree and information of a child part is arranged on a branch side of the tree.
It is preferably the first Web page to be displayed on the W client device. Further, the first Web page is characterized by including data of each component constituting the tree and a script for causing a WWW client device to create the tree using the data. If you do this,
Since the processing load for creating the tree can be distributed to the WWW client device that displays the tree, the processing load does not concentrate on the WWW data server device, and the efficiency of the tree creation process can be increased.

[0009] Further, a component designation receiving means for receiving from the WWW client device a component designation for designating one component information from the component information displayed in the tree, and when the component designation is received, the component information is used. And generating second display information for displaying a tree in which the information of the specified part is arranged at the root of the tree, the information of the child part is arranged at the root of the tree, and the information of the parent part is arranged at the branch side of the tree. 2 display information creating means, wherein the display information sending means comprises:
Further, the second display information is sent to the WWW client device.

[0010] By constructing the tree in this way, parts having a specified part as a constituent part and a product using the specified part can be seen at a glance. You can easily know the effect on the product. For example, when changing the size or shape of a part,
It is necessary to consider whether a part whose size or shape has been changed can be successfully incorporated into the parent part. According to this tree display, the parent part can be easily specified. For example, a CAD drawing of the parent part can be created immediately. Can be displayed. Therefore, it is possible to greatly save the trouble of searching for drawings, so that design work can be efficiently and smoothly performed.

The second display information created by the second display information creation means is such that the information of the designated part is the root of the tree, the information of the child part is on the root side of the tree, the information of the parent part is Is a second Web page that displays a tree in which is arranged on the branch side of the tree. Further, the second display information creation means creates the second display information by sequentially searching the database for a parent part having a part included in the predetermined data as a child part, and The sequential search is started from a search for a parent component having the component included in the specified data as a child component.
In this way, a tree as described above can be created.

Further, the second Web page stores data of each component constituting the tree and a WW using the data.
A script for causing the W client device to create a tree is included. With this configuration, the processing load for creating the tree can be distributed to the WWW client device that displays the tree, so that the processing load does not concentrate on the WWW data server device, and the efficiency of the tree creation process can be increased. .

[0013] The first display information includes a script for sending, to the WWW data server device, a component designation for designating the information of the clicked component when the component information displayed in the tree is clicked. It is characterized by including. By doing so, it is possible to specify a part while the tree is displayed and send it to the WWW data server device, so that it is possible to reduce the trouble of displaying the tree with the part as the root.

The data stored in the database includes file information indicating an electronic file associated with the data, and type information indicating a type of the electronic file, respectively. And a storage request receiving means for receiving a storage request for storing the electronic file and the type of the electronic file in the database, wherein the database stores a distribution destination table indicating destinations for distributing the electronic file for each type. ,
A storage unit that stores the electronic file and the type according to the storage request in the database; and a distribution unit that distributes the electronic file to a destination corresponding to the type according to the storage request with reference to a distribution destination table. And

[0015] In this way, the user who registers the technical document does not need to know the destination to which the technical document is to be distributed and specify the destination, and the distribution route of the technical document can be related to the technical document by the WWW data server device. Since it can be centrally managed, the trouble of distributing technical documents can be reduced and at the same time erroneous distribution can be eliminated. Further, the WWW data server device according to the present invention is characterized in that the WWW data server device includes a reception confirmation unit for confirming that the destination has received the electronic file.

[0016]

FIG. 3 is a diagram showing the structure of the database. The database includes a parts database including a parts list, a technical document list, and a child parts list, and three master files of a technical document type master, a distribution destination master, and a department code master. The component list of the component database stores the component codes and component names of all components including products that have no parent component. The technical document list stores the codes of the components listed in the component list and the technical document codes, technical document names, and technical document types of the technical documents related thereto. Further, the child part list is a list showing child parts of each part, and includes a part code of each part, a child part code which is a part code of a child part of the part indicated by the part code, and a child part code. The part name of the part to be stored is stored.

As described above, the master file has three files: a technical document type master, a distribution destination master, and a department code master. The technical document type master corresponds to the technical document type and each technical document type. It is a correspondence table of a technical document type name. The distribution destination master is a file indicating the department that distributes the technical document corresponding to the technical document type, and is a correspondence table between the technical document type and the department code. Further, the department code master includes a list of department codes, department names, and mail addresses. In addition, the e-mail address attaches a newly registered technical document or a revised technical document to the e-mail,
This indicates the destination of the e-mail to be sent to a specific department. Therefore, when a technical document type is designated, these master files are sequentially referred to to determine a destination to distribute a technical document having the technical document type, that is, a mail address.

The child parts list of the parts database is stored in the WW format when a CAD drawing compliant with JIS (JIS Z8311: drawing size and drawing) is registered in the database.
It is updated by the W data server device 2. That is,

FIG. 5 is a diagram exemplifying the reference screen. On the reference screen 20, all parts are displayed in a tree based on their relevance. In other words, a branch is extracted from a product or part, and a part having the product or part as a parent part is displayed. At this time, at the position corresponding to the root of the tree (hereinafter referred to as “root”), information on the product, which is a part having no parent part, is arranged, and on the same line, an icon representing the product, a product code, and a product name Are displayed side by side. For components other than products, icons representing the components, component codes, and component names are also displayed side by side in one node at the nodes of the tree.

In FIG. 5, for example, for the product 1, an icon 23 representing the product 1 and a part code 2 are provided at the root of the tree.
1, a part name 22 is displayed, and a branch (a broken line in the drawing) from the icon 23 indicates a part 1, 7,
And 8 are drawn out. Further, an icon 24 representing a component is displayed on the component 1, and a branch is drawn out toward the component 2 having the component 1 as a parent component.
From the parts 3 and 4 with the part 2 as the parent part, and the part 4
, Branches are drawn out toward the parts 5 and 6 having the part as a parent part. In this way, by displaying the parts in a tree view, the relationship between the parts becomes clear at a glance, and for a specific part, the material used for the part can be easily referred to.

Further, the icons displayed on the reference screen 20, for example, the icons 23 and 24, are linked to the component information reference screens of the corresponding components, and when one of these icons is clicked, the icon is clicked. The component information reference screen of the corresponding component is displayed in another window. Therefore, it is possible to refer to the technical information of each component while viewing the tree display.

FIG. 6 is a diagram showing an example of the component information reference screen. The component information reference screen 30 is a multi-frame window including four frames of a data display frame 31, a technical document frame 32, a parent component frame 33, and a child component frame 34. Data display frame 31
In the text box, a part code, a part name, a registration date, and a person in charge are displayed, and technical information such as a rated voltage is also displayed. These pieces of technical information can also be updated on the component information reference screen 30. The technical document frame 32 is a frame that lists the file names of technical documents (electronic files) related to the components displayed in the data display frame 31. A link is set to each of the displayed file names, and when the place where the file name is displayed is clicked with a mouse, the content of the electronic file, that is, the content of the technical document is displayed.

The parent component frame 33 is a frame that lists component codes and component names of parent components of the component displayed on the component information reference screen 30. The child part frame 34 is a frame that lists the part codes and the names of the child parts of the parts displayed on the part information reference screen 30. The frames 31 to 34 are
When the display data cannot be completely displayed in the frame, a scroll bar for moving the display data up and down, such as the scroll bars 36 and 37, is displayed to enable scrolling.

When the "register" technical document button 35 is clicked on the component information reference screen 30, a technical document registration screen shown in FIG. 7 is displayed. The technical document registration screen 40 displays the technical document code, technical document name,
And text boxes 41, 42, and 45 for inputting a technical document type and a text box 46 for displaying a component code of a component to be mainly described in the technical document. Further, two buttons of a reference 43 and a registration 44 are also displayed.

When a "reference" button 43 is clicked on the technical document registration screen 40, the Ja attached to the Web page is clicked.
The va script is activated and the storage device (HD, FDD, etc.) of the WWW client device displaying the screen
Is referred to, and the content is displayed in another window. When the user selects the file name of the technical document to be registered, the file name of the technical document is input to the text box 42. When the text box 45 is clicked, a list of all technical document types is displayed, and a technical document type to be input can be selected from the list. Similarly, when the text box 46 is clicked, a list of component codes is displayed, and a component code to be input can be selected from the list.

When the "Register" button 44 is clicked on the technical document registration screen 40, the file entered in the text box 42 is stored in the database. The file name of the technical document registered in the document frame 32 is displayed. At the time of registration, the files of the technical document type master, the distribution destination master, and the department code master are referenced according to the technical document type, and the mail address of the distribution destination to distribute the registered technical document is determined.
The registered technical document is finally attached to an e-mail and transmitted to the e-mail address.

"Registration" button 12 on entry screen 10
When clicking, the component information reference screen 30 of FIG. 6 is displayed. At this time, nothing is displayed in the text box of the data display frame 31, and the technical document frame 3
2. Nothing is displayed on the parent part frame 33 and the child part frame 34. Frames 31, 33, and 34 other than the technical document frame 32 are registered by directly inputting data. Further, the technical document can be registered by clicking the technical document “register” button 35. When a component is registered on the component information reference screen 30 in this way, the registered component is automatically added to the tree of the reference screen. (Generation of Tree) Now, a generation procedure of the tree shown in FIG. 5 in the WWW data server device 2 will be described.
The HTTP server of the WWW data server device 2 is WWW
When a request for displaying the reference screen 20 is received from the client device 4, the gateway program is started and an HTML (Hypertext Markup L) for displaying a tree is displayed.
(anguage) is created. FIG. 8 is a flowchart showing a procedure in which the gateway program generates a tree. When activated by the HTTP server, the gateway program issues a query to the RDBMS and searches for a product, that is, a component having no parent component (step S1). More specifically, a part code that does not appear in the part code section of the child parts list is searched by comparing the part code section of the parts list with the part code section of the child parts list. A list of products found as a result of the search is created (step S2). FIG. 9 is a diagram showing the result of step S2 when the tree shown in FIG. 5 is created. For each product found by the search, a product code and a product name are displayed next to the icon indicating the product. This list is created as a Web page.

The information on each product found in step S1 includes information on the child parts (child part code and child part name) of the product, and the information is used immediately after each product in the list using the information. Add and insert the display of child parts of the product.
That is, an icon representing a component, a component code, and a component name are displayed for each component following the symbol character representing the branch of the tree, and a first-stage tree is generated (step S3). FIG.
(B) is a diagram showing a first-stage tree. The child parts of each product are displayed so as to be connected to a branch extending from each parent part product.

Next, with respect to each component constituting the tree of the first stage, a child component thereof is further searched (step S).
3). If no child part is found (N in step S4)
O), the process ends. If a child part is found (YES in step S4), the newly found child part is displayed on the line next to the line on which each part in the first row is displayed, and is set as a tree in the second row (step S5). ). For each component displayed in the second tree, an icon representing the component, a component code, and a component name are displayed side by side. FIG. 9 (C) shows 2
It is a figure showing the tree of the stage. In FIG. 9C, the component 1
In contrast, a part 2 which is a child part of the part 1 is additionally displayed. When step 6 is completed, the process returns to step S4, and for each of the components constituting the tree of the last added stage, further searching for child components thereof (step S4).
3) This process is repeated until there are no child components whose parent component is the component displayed in the tree. In this way, a product or a component can be displayed in a tree based on the component configuration information, so that the component configuration of the product or the component can be easily grasped.

When the "registration" button 44 is clicked on the registration screen 40 shown in FIG. 7, the gateway program performs the following processing. FIG. 10 is a flowchart showing the process. First, the gateway program issues a query to the RDBMS, and causes the distribution destination master to search for a department code corresponding to the input document type (step S10). Next, a department code obtained by the search is designated, and a query for searching for the department name and the mail address corresponding to the department name is issued from the department code master (step S11). The gateway program inserts the department name and the document name obtained by the search into a standard mail text (step S1).
2) After the registered document is encoded into an attached file format (step S13), the document is attached to the e-mail (step S14), and a transmission is requested to the mail server (step S13).
15). The mail software installed in the mail terminal that is the destination of the e-mail has a function of automatically notifying the source of the e-mail when the user opens the received e-mail. Whether or not to use the function is specified by the sender of the e-mail attaching predetermined information to the e-mail. This allows the WWW data server device 2 to manage information on whether or not a technical document including information on a specification change or the like has been delivered to the relevant department. Also, when attaching a technical document to an e-mail, it is preferable to attach only a changed page, since the amount of communication can be reduced.

Although the present invention has been described based on the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and the following modifications can be made. (Modifications) (1) In the above-described embodiment, the case where a product is arranged at the root when displaying a tree on the reference screen 20 has been described. It is good. FIG. 11 is a diagram showing a reference screen 50 replacing the reference screen 20. Like the reference screen 20, the reference screen 50 is activated by clicking the "reference" button 11 on the entry screen 10, and displays a tree in which products are arranged at the root. Also, reference screen 5
0 has a menu bar 51 unlike the reference screen 20, and the menu bar 51 is provided with a “tree update” button 53. When the icon of any component displayed on the screen is clicked, the reference screen 50 reversely displays the icon. Further, when the "tree update" button 53 is clicked in this state, the selected component is arranged at the root of the tree, and the product or component having the component as a component is arranged at the node of the tree. indicate.

For example, in FIG. 11, the "tree update" button 5
When 3 is clicked, a tree as shown in FIG. 12 is displayed. That is, the icon 52 of the component 2 is arranged at the root,
The component 1, the product 2, and the product 3 having the component 2 as a child component are displayed at the ends of the branches extending from the icon 52 of the component 2.
Further, the product 1 having the component 1 as a child component is displayed at the tip of a branch extending from the component 1. At this time, the menu bar 51
Further, a "return" button 54 is displayed. When the "return" button 54 is clicked, the reference screen 50 is displayed again in FIG.
Display 1 tree. When the icon of any product or component displayed on the screen is double-clicked, the reference screen 50 starts the component information reference screen of the product or component.

FIG. 13 is a flowchart showing an operation of updating the tree by the gateway program. When the "tree update" button 53 is clicked, the gateway program creates a Web page displaying the clicked component (step S20). Next, RDBMS
Is issued, and a parent part of the clicked part is searched (step S21). If the parent component is not found as a result of the search (NO in step S22), the process ends. If YES in step S22, the Web page is updated, and the found parent part is added to the tree (step S23). When step 23 is completed, the parent component is further searched for each component constituting the tree of the stage added last (step S21), and this processing is performed until there is no parent component having the component displayed in the tree as a child component. repeat.

FIG. 14A is a view showing the Web page created in step S20 after the "tree update" button 53 is clicked while the icon 52 in FIG. 11 is highlighted. Only the part 2 for which is clicked is displayed. FIG. 14B is a diagram showing the Web page updated only once in step S23, in which parts 1, product 2, and product 3, which are parent parts of part 2, are added to the tree. FIG. 14C is a view showing the Web page updated twice in step 23, and the product 1 which is the parent part of the part 1 is added to the tree.

By doing so, it is possible to designate a part and to display a parent part having the part as a child part and the parent parts of those parent parts in a tree view, so that the design of a specific part can be changed. In addition, it is possible to easily know the parts that are technically or costly affected by the change. (2) In the above, the WWW data server device creates a tree in advance and displays the tree on the Web.
The page was sent to the WWW client device,
Instead, a Java script for creating a tree and information (including information on parent-child relationships) of parts constituting the tree are attached to a Web page and sent to a WWW client device, and the WWW client device transmits the Java script. It may be executed to create and display a tree.

In this way, the processing load for creating a tree can be prevented from being concentrated on the WWW data server device, and the processing load can be distributed to each WWW client device that wants to display the tree. Therefore, especially when a plurality of trees must be created at the same time, the processing time for creating the trees can be reduced.

(3) In the above embodiment,
When the tree is generated, all parts having no parent part, that is, all products are searched first (step S1), and all trees having these as roots are generated. Instead, the following is performed. May be. That is, first, WW
The W data server device displays a Web page on the WWW client device, and allows the user to search for and specify a product or component to be arranged at the root of the tree to be displayed, using a component code or the like as a keyword. Further, in the Web page, it is determined whether to generate a tree in which child parts of the specified part are arranged in a branch of the tree having the specified part as a root, or to generate a tree in which parent parts are arranged. Let the user specify it. Then, the WWW data server device generates a Web page for displaying a tree based on these designations in the same manner as in the above embodiment, and causes the WWW client device to display the generated Web page.

When the user clicks an icon of any part on the Web page displaying the tree,
This is notified to the WWW data server device, and the WWW data server device allows the user to specify which of the parent component and the child component of the component is to be arranged at the branch of the tree having the component at the root. Is displayed on the WWW client device. Then, when the user designates the arrangement on the Web page, a Web page for displaying a tree is generated in the same manner as in the above-described embodiment, and is displayed on the WWW client device.

In this way, only the tree that the user wants to display can be displayed on the WWW client device, so that the Web page for displaying the tree can be made compact. Therefore, a Web page for displaying all the trees with each product as a root is generated, and the Web page is transmitted from the WWW data server device to the WWW server.
A WWW data server device required for transferring to the WWW client device and displaying on the WWW client device;
The load on the WWW client device and the network can be reduced.

(4) In the above embodiment,
The mail software installed in the WWW client device 4 automatically notifies the sender of the e-mail when the user opens the received e-mail, but the following may be adopted. That is, the electronic mail transmitted by the gateway program when the “register” button 44 is clicked is assumed to be an HTML mail, for example, <form action = "http: // [program name]"><input type = "submit" value The user who receives the e-mail by inserting a text such as = "Receipt notification"></form>, where the program name is the name of a program that returns a receipt notification to the WWW data server device The reception may be confirmed by activating a predetermined program.

In this way, since the person who has been notified of the registration returns a notification of his / her own volition, it is possible to clearly confirm that the notified person has approved the reception of the notification. (5) In the above embodiment, the WWW data server device is provided with the mail server.
The W data server device may be used as a mail client, and electronic mail may be transmitted and received via a mail server provided separately. By doing so, the processing load on the WWW data server can be reduced.

(6) In the above embodiment,
Although the technical document is updated (registered, modified, deleted) from the WWW client device, the update of the technical document from the WWW client device is prohibited, and only a specific client device, for example, a client installed in the technical management department The technical document may be updated only from the device. By limiting the means for updating the technical document in this way, it is possible to prevent the technical document from being altered or lost intentionally or by mistake, and to improve security.

(7) In the above embodiment,
Attach the Java script to the Web page,
Although the va script is configured to execute various processes, the va script may instead be activated to cause the WWW data server device to execute a program for performing the process in response to an instruction from a Web page.

As described above, according to the present invention,
Since all parts are displayed in a tree based on the parent-child relationship of the parts, the relation between the parts becomes clear at a glance, and for a particular part, the material used for the part can be easily referred to. In addition, the parent part that has the specified part as a child part is displayed as a tree, including the parent part of the parent part, so that the cost of that part, such as design change and cost of a specific part, affects which parts and products. Can be easily known.

Further, when distributing technical documents,
Registering the relationship between departments in the master file in advance and automatically distributing technical documents to the required departments by e-mail according to the master file, distribute the technical documents only by registering the technical documents in the database can do. Therefore, since the user who registers the technical document in the database does not need to specify the distribution destination of the technical document, there is no need to know the change of the department in charge or the person in charge and specify the destination, and distribute the technical document. Time and effort can be reduced.
