Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION In a railway that can run only on laid rails, that is, it can run while avoiding other vehicles, when a large number of vehicles have to come and go at the same time, collision and contact are prevented. I have to
The safety device therefor is an interlocking device. The interlocking device is equipped with detailed logic that controls traffic lights and rolling devices. The interlocking device is the key to the safety of railway operation. The present invention relates to generation of a "linkage chart" that is a document that describes the linkage logic of a linkage device.

[0002]

2. Description of the Related Art The shape of a track is drawn on paper and an expert traces it with his hands and eyes to determine the logic. The determined logic is tabulated as a "linkage table". (A "wiring diagram" that draws the wiring of the track and a "interlocking table" that lists the interlocking logic are called a "interlocking diagram.") If the campus has many tracks, the enumeration items will be enormous. However, since we want to reduce the writing amount as much as possible for handwriting, and because the interlocking chart is an official document for security assurance and some reorganization requires an official procedure, a small amount is required.・ It has become a notation that pursues simplicity. Therefore, there are many conventions and special symbols, and what is considered to be common sense in the world, that is, what you can naturally learn if you are skilled, and what you can infer from the matters that are exposed, the rule is not to write Is very difficult to understand. The skilled person naturally creates the interlocking logic by taking into consideration various surrounding factors such as topographical constraints, train operation density, equipment cost, etc.

The enormous amount of work involved in creating interlocking diagrams is due to the so-called clean copy work of preparing the formats of wiring diagrams and interlocking tables.
It can be broadly classified into trial and error and confirmation work for deciding logic before clear copy.

As a support method for creating an interlocking chart, it is widely used to use a drawing or tabulation tool. This only reduces the clean copy work, and does not change the burden of human thought during trial and error and confirmation. As an attempt to reduce trial and error and confirmation work, there is JP-A-6-191407. Here, the devices that make up the interlocking logic are represented by blocks to input the information necessary for control to eliminate human omissions and mistakes when creating the logic. It is necessary to manually perform the two steps of creating a wiring diagram and interpreting it to express a block. JP-A-6-120
In the publication No. 55, the drawing made on the screen is used not only as a clear copy but also as original data for extracting information specific to the wiring diagram. However, the drawing method here can be used after the position of the track circuit boundary and the shape of the track circuit are determined, and is not suitable for support when the position of the track circuit boundary itself is still subject to trial and error.

"Track circuit": An "electric circuit" (detection device), which is originally a "track circuit" for detecting the presence of trains. In turn, the line range in which it is placed and the on-rail detection unit. Where there is a branch in the station yard, the track may be branched, and even if a considerable number of branches are included, it may be a single track circuit, so the track range recognized as a single track circuit may have a considerably wide spread. is there.

[0006]

[Problems to be Solved by the Invention] Since it is difficult to create an interlocking chart, it is necessary to decide the contents before the fair copy.
It is an object of the present invention to support trial and error and content confirmation work at the content determination stage. That is, when the content of the interlocking chart is decided, the problems of the present invention are as follows: (1) Different considerations depending on the creator: safety and efficiency, or a large number of considerations that extend to the business environment and their objective judgment criteria. Because of the inadequacies, the logic is constructed with thinking that depends on the skill and experience of the person in charge. In addition, the "interlocking table" simply leaves only the final result, without leaving any thought process or reason in the middle. Therefore, even if different "interlocking tables" are created for different people, other people (unskilled people) may not understand the reason for the difference. (2) Careless mistakes are hard to get rid of: Careful mistakes such as oversights can occur when setting a complicated course in a large campus because a person is a skilled person. Therefore, it is said that several people will take several days to several months for the confirmation work. It is necessary to reduce the load due to these obstacles. The present invention provides a method capable of shortening the training time for linked engineers, shortening the linked chart creation time, improving accuracy, and / or ensuring objectivity up to the result (completion of linked chart) and sharing knowledge. It is to be.

[0007] Of the various surrounding requirements considered by the skilled person, the matters concerning safety and efficiency are objectively classified.

[0008]

[Means for solving the problem] The boundary and criteria of the surrounding conditions to be considered such as topographical constraints, train operation density, equipment cost of interlocking device, etc. are not clear at present. It is impossible to automate and human intervention is essential. Therefore, we adopt a method that allows people and computers to work together in a coordinated manner. Input and output (confirmation of results) are performed in the form of figures that are most easy for humans to understand, and the computer is in charge of simple but enormous labor-intensive processing such as searching in the middle and listing results. Use the power of the computer to enumerate even a large amount of information that is likely to be a reference material for human judgment. The present invention decomposes the process from the wiring schematic diagram to the interlocking table, which has been processed in the human head until now, and presents the process to the human, thereby prompting the human to think, and the correct interlocking table. To support the output of.

BEST MODE FOR CARRYING OUT THE INVENTION As one embodiment of the present invention, the present invention is incorporated in a device called "interlocking diagram creation support tool". Therefore, before starting the description of the scope of the invention, the development purpose, configuration, and effect of the entire apparatus will be first outlined. The following is a description of the entire device and the description of the present invention, with reference to the drawings. [Explanation of the entire device] 1 Necessity of interlocking diagram creation support tool The interlocking diagram is a diagram showing the equipment configuration and interlocking mechanism of the interlocking device at the station or the stop, and the signal / replacement sign at the station. -It also includes the equipment status of the rolling equipment and the contents of train operation on the premises. In other words, it is the basis of all work related to train operation. Therefore, in terms of security, the interlocking conference including all related departments will decide the creation and modification of the interlocking chart.

[0010] The general flow until the final interlocking chart is created is such as determining the train operation policy at that station, determining the track shape, determining the signal equipment, and determining the interlocking. This series of examinations is not always decided in order, and for example, the shape of the tracks and the layout of signal equipment may be restricted by the terrain, and as a result, the examination may go back to the stage of reviewing the operation itself. Thus, a great deal of study work is required before the final determination of the interlocking chart.

Further, even when the manufacturer converts the determined interlocking chart into the data for the electronic interlocking device, work by a skilled person is required. First, an expert in signal business analyzes the interlocking chart presented by the railway company to create a data table for interlocking device, and converts this into final data by the interlocking data conversion system. The interlocking chart contains items related to security and operation that are very centralized and described, and since there are many parts that depend on the know-how of skilled personnel, these operations also take time and labor, and the electronic interlocking device It is a big limitation in the process of new introduction / repair.

In order to solve the above problems, various techniques have been studied so far for creating an interlocking chart.

Regarding the method of creating the interlocking table from the information of the wiring diagram, the derivation of basic conditions such as locking, locking and signal control has been reported in [1] and [2]. However, the detailed conditions included in the actual interlocking table, such as the conditions of equipment outside the route, the closed loop lock, and the phoneme, have not yet been considered. In [3], conditions such as closed-loop lock, approach-lock, single-lock, etc. are also taken into consideration, but this is treated as information that can be additionally input by the expert's judgment.

In order to consistently support the interlocked chart creation work, it is desirable that the system automatically extracts the candidates of various conditions necessary for the interlocked chart as much as possible. This report describes the configuration and features of the interlocking diagram creation support tool (hereinafter referred to as support tool) developed to solve this problem. 2 Concept of support tool As mentioned in the previous chapter, there are a lot of tasks until completion of the interlocking chart. For example, in any task such as decision of train operation policy, linear selection suitable for operation, and signal equipment arrangement. Tool support is desired. The purpose of this support tool is to realize a function that supports the task of creating the interlocking table from the wiring schematic input.

In the creation of the interlocking chart, the correction / change of the contents in the upstream process (operation policy / linearity / course setting)
The wiring diagram and the interlocking table as a whole are greatly affected. Therefore, a great deal of labor is required to confirm the wiring schematic and the contents of the interlocking logic. Therefore, by automating this work process,
The efficiency of creating interlocking charts can be greatly improved. 3 Configuration of Support Tool Figure 1 shows the procedure for creating data for electronic interlocking devices using the support tool. The support tool is composed of the following three modules.

(1) Drawing input interface (2) Interlocking logical data creation module (3) Input wiring schematic diagram in drawing input interface of interlocking table data output module (1), analyze the data, and interlock (2) The basic data of the interlocking table is created by the logical data creation module. This data has a general-purpose structure so as to be compatible with various interlocking table formats. The interlocking table data output module of (3) outputs the interlocking table in a predetermined format. The following modules will be described. 3.1 Drawing input interface When creating a new interlocking diagram, input the line configuration and signal equipment layout as a drawing using the drawing input interface shown in Fig. 2. The parts necessary for drawing the wiring diagram are prepared in the input interface, and the wiring diagram can be easily created simply by arranging the line patterns and traffic signals.

The information to be input is basically ・ Track information ·traffic light ・ Course information Is.

(1) A track part is drawn by dragging and dropping a track part from the track information part menu. The track circuit only needs to place the boundary components at the appropriate places on the track. The name of the track circuit is automatically recognized as the name of the track circuit only by appropriately arranging the parts. To enter the name of a part, use the dialog by double-clicking the part (or selecting the menu). For other parts, various attributes can be specified in the dialog as well.

The branch is also placed at the branch part of the line to place the switch part. It is determined that the rolling machines with the same number (difference of Iroha) will automatically perform two motions (or three motions or more).

A drawing component for a three-dimensional intersection of railroad tracks is also prepared, which is distinguished from the crossing.

The contact limit indicator can also be placed as a component and is used to determine whether or not the signal control of the track circuit is affected.

(2) Traffic signals As traffic signals, various traffic signal parts such as on-site / departure traffic signals, interchange traffic signals, and ATC traffic signals are prepared. The displayed pattern can be specified by a dialog as an attribute of a traffic light, and is automatically reflected in the display of parts. Other information that can be specified by the dialog includes a route indicator and a hold.

A planting position part for a traffic light is also prepared, and the installation location of the traffic light can be described explicitly. The installation position of the traffic signal is used for automatic determination of the closing condition by the determination based on the positional relationship with the track circuit boundary.

(3) Route information The route can be specified by explicitly associating the route name (traffic light) with the starting point and the ending point. Input method is as follows: ・ List of route name, starting point and ending point: You can specify the route name on the wiring diagram and the link between the starting point and the ending point by the route table and the parts for specifying the route. Is.

The overrunning protection range can also be designated by the overrunning section termination component in the same manner as the course. The drawing input interface is realized by an extension function of a general-purpose drawing tool, and it is possible to input a wiring schematic diagram intuitively and efficiently. 3.2 Interlocking logical data creation module The interlocking logical data creation module automatically extracts basic interlocking logical data by extracting the route configuration and signal conditions from the graphic data created by the drawing input interface and the attributes related to the equipment. create. FIG. 4 is an interface screen of this module. The processing in this module will be described below.

(I) Drawing Component Recognition Wiring Diagram Since the drawing data is basically only the drawing information and component attributes of the component, individual component information is analyzed in order to recognize the wiring diagram and extract the route information. . For example, in order to recognize the track circuit, all the intersections of the line components and the track circuit boundary are obtained, and the information is configured as each track circuit. Then, the positional relationship with the track circuit name component is checked to recognize the name of each track circuit. Also, the connection relation of each track circuit is recognized from the continuity of the line parts and the branch position. FIG. 3 shows a wiring diagram drawing component.

Similarly, the relationship between the traffic signal, the route, the starting point and the starting point is recognized and configured based on the information and attributes of the respective drawing parts.

(Ii) The connection of the track circuits extracted in the track information recognition (i) is searched, and the information of the track circuits / rollers and the adjacent track circuits included from the starting point to the ending point of the track is obtained. Extract. When a plurality of routes are detected for one set of starting and ending points by the search, all are presented to the user as options. Here, in order to avoid detecting meaningless routes that are impossible in reality,
The search direction is limited to the direction in which the train can proceed. For this reason, reference is made to the crossing angle of the track at the branch or intersection. Information about the recognized path can be confirmed graphically. Information about the path recognized by the tool,
Display using the graphic data created by inputting the wiring diagram. It is possible to visually confirm the starting and ending points, the adjacent track circuits, and the names of the rolling devices included in the route. FIG. 5 shows a route information display screen.

(Iii) The route candidates extracted by the route candidate generation search are output as a list. It also displays all the possibilities (multiple routes, overruns, opening levers, etc.) for one course. In order to provide the user with information that cannot be explicitly determined only from the wiring diagram, a lot of information regarding the route is enumerated. The information described in the normal interlocking table is very concentrated in order to simplify the description, and the know-how and judgment of experts are often incorporated. In this tool, by enumerating the information of the process of deriving the interlocking logic, it is possible to share the items related to expert know-how as clear information.

FIG. 6 shows a table of route candidate information. The main items extracted from this list are the track name, starting point and starting point track circuit, overrun protection limit, passing track, track circuit inside track and rolling device, adjacent track circuit and rolling device, closed circuit. Conditions etc.

Items to be selected by the user, for example, the type of lock when overrunning, passage route, out-of-course track circuit and rolling device to be considered are operated from this list.

Further, as the information regarding the route, a route-to-route relation table in which all the generated route candidates are checked for a competitive relationship is also generated at the same time. This table enumerates relationships between various paths, such as the direction of the path, the intersection of the paths, and the inclusion relationship of adjacent track circuits. Figure 7
A list of inter-course relations is shown in. These related information can also be confirmed on the route information display screen of FIG.

After the selection items are designated, the route candidate list is converted into route information as shown in FIG. The user uses this table to add information such as railroad crossing conditions, approach lock conditions, and time points that cannot be determined only by the line shape. 3.3 Interlocking table data output module The route information list generated by the interlocking logical data creation module is a file of a general-purpose format. The interlocking table output module converts it into a desired format and outputs it as an interlocking table. The output format depends on the user's request, but since detailed information is listed in the route information list, it is possible to correspond to a general interlocking table format.

FIG. 9 shows an output example of the interlocking table. The interlocking table data in this format can be automatically converted into electronic interlocking device data by a data conversion tool at our company.

As described above, the efficiency of the work from the wiring schematic data input to the interlocking table creation is greatly improved by this support tool. 4 Features of support tools The features of creating interlocking diagrams with support tools are summarized below. -Automation of extraction and verification of various information related to interlocking logic The process that used to rely on manual work has been automated.

Work items: extraction and confirmation of the layout relationship between the route, the track circuit and the rolling machine, verification of the obstacle relation between the multiple routes,
Section where overrun should be taken into consideration ・ Confirmation of the position of vehicle contact limit, etc. ・ Data consistency guarantee by electronic computerized management of drawings From data input to interlocking table output, data is electronically managed, so interlocking The data update work for renovation becomes easy. -Applying drawing data and interlocking logic data to peripheral devices Drawing data can be easily applied to various screen data such as interlocking device terminals. Of the data related to linkage created by this tool, route information, screen data, operating conditions, etc. can also be applied to operation management systems. By sharing data among various signal-related systems, system development efficiency and data maintainability can be improved. -Improvement of work efficiency by creating interactive charts Applicable to planning and pre-evaluation when introducing a new interlocking device. Furthermore, even in interlocking renovation, it can support trial and error work from the planning stage and improve productivity. Can be made. -Sharing and inheritance by sharing technology and knowledge electronically Candidates for matters that need to be taken into consideration when constructing logic are clearly indicated, so that knowledge that was the know-how of experts can be shared and inherited. It can also be used for interlocking device education for newcomers. [Explanation of the Present Invention] The present invention is the method adopted in the "interlocking logical data creation module for analyzing basic wiring diagram data by analyzing wiring schematic data" in the above description.

FIG. 9 shows the configuration of this method. In the figure, 1 is a schematic wiring diagram drawn by hand, 2 is a human thought for interpreting the judgment, 3 is an interlocking table created by a human, 4 is a schematic wiring diagram input on a computer screen, 21 is a computer process and human cooperation. 2 shows the alternative processing steps of 2 so far, 14 is the interlocking table obtained from 21.

FIG. 10 is a detailed version of the contents of 21 in FIG. 9. 5 and 6 are information that can be obtained from the wiring schematic diagram of 4, 7 is information that cannot be obtained from the wiring schematic diagram, and 8 and 9 are human judgments. 1
Reference numerals 0 and 11 indicate the meaning of coalescing and collating the information, 12 is a table arranged as route information, and 13 is the content thereof. Of the 5 and 6 information that can be obtained from the wiring diagram, 5 is the information obtained from the wiring diagram as it is and flows to the course information 12, and 6 is information obtained from the wiring diagram that is selected by human judgment and the course information 12 Indicates that

The path may be determined by the information alone,
In order to improve efficiency (to move as many trains as possible within the station yard), it is necessary to consider the relationship with other routes. Relations with other routes are calculated at 15. Based on the result, a person decides whether the information on the route is over or under 1
7 or logic 18 is used for determination and reflected in the route information 19. The track information 12 or 19 is included in the interlocking table 14.

11 to 8 show, in order, the method of obtaining 5 and 6 which are the source of the route information in FIG. 9 or 10.

FIG. 11 shows the definitions of "route", "route", and "step".

When the train runs from the starting point 26 to the ending point 27 of a certain route, the train actually steps on the track indicated by 28.

A course is defined by a train circuit sequence including a stepping track, and in the case of this course, 29, 30, 31, 3
It consists of two orbital circuits (the "path" in general recognition).

Here, a "route" is defined as a track circuit which is decomposed along a route through which a train can pass. Even if there is a branch in the track, the train does not bend in an acute angle, so the route of the track circuit 29 is 33, the route of the track circuit 30 is 34 and 35, and the route of the track circuit 31 is 36, 37 and 38. ,
The path of the track circuit 32 becomes 39.

The trains 33, 34, 37 and 39 of the routes forming the route 28 on which the train actually travels are defined as "steps".

Since the possibility of contact between trains greatly affects the logic related to the safety of interlocking, the logic cannot be precise unless the places where train cars actually pass and the places where train cars do not pass are clarified. “Tread” is the concept introduced for that purpose. When humans (experts of interlocking) think about the interlocking logic, they are aware of it, but it was not explicitly shown as a matter of course. "Track circuit" was recognized as the minimum recognition unit. For humans, especially for experts, it is "what you can see", but since it was necessary to make a fine classification to perform a mechanical search with a computer that has no eyes and no can, "route""step" Introduced the idea of, and made the resolution of recognition finer.

Prior to collecting route information from the wiring diagram,
As a preprocessing, the track circuits and the "paths" belonging to them are recognized for all the lines in the figure.

FIGS. 12 and 13 show the collection order of information collected from the wiring schematic diagram as a source of the information of the route.

A path, a track circuit, and a tumbling device having a range of influence and a range of influence may be searched centering on a step.

At 40, the starting and ending points designated as the route are recognized.

At 41, a route group connecting the starting route and the ending route is extracted. This is a footpath.

At 42, a track circuit is extracted from the track determined at 41.

At 44, the rolling device in the step is extracted from the step determined at 41.

At 45, the track circuit extracted at 42 and 4
From the rolls extracted in 4, the rolls that are in the path but not in the footpath are extracted.

In 46, the rolling device extracted in 44 is moved to extract the rolling device in another track circuit which is simultaneously moved.

In 47, the rolling device extracted in 45 is moved to extract the rolling device in another track circuit that is simultaneously moved.

At 48, a route which comes into contact with a route forming a step, that is, a route which faces the contact limit point is extracted.

At 50, a track circuit adjacent to the track circuit group including the track obtained at 42 is extracted.

At 51, the rolling devices included in the track circuit group obtained at 50 are extracted.

From the above, the track circuit / roller on the "pedestal" which must be taken into consideration when setting the course,
The track circuits and rolling devices around the pedestrians that have certain influences or may have been extracted have been extracted.

14 and 15 re-enumerate the track circuit / roller obtained in FIGS. 12 and 13. The arrows in the figure indicate the extraction order described above.

Reference numeral 64 indicates a route which constitutes a step.

Reference numeral 65 indicates a track circuit including a path forming a step.

This is the "path" in the general definition,
It is a range where the train cars pass, and even if they do not pass, they belong to the same track circuit and can be detected as if they were passing.

Reference numeral 66 denotes a route which does not constitute a footpath and belongs to a track circuit including a route which constitutes a footpath.

Reference numeral 67 indicates a rolling device included in a path which does not constitute a footpath belonging to a track circuit including a path which constitutes a footpath.

Reference numeral 68 denotes a turning device that simultaneously converts with a turning device included in a path that does not form a footpath that belongs to a track circuit that includes a path that forms a footpath.

Reference numeral 69 denotes a rolling device included in the route forming the footpath.

Reference numeral 70 designates a turning device which is simultaneously converted with a turning device included in a path forming a footpath.

There is a type of tumbler which is designed to move a plurality of trolleys with a single operation instruction.

In the case of such a multi-action switch, one side split is moving in another track circuit not included in the route.

Reference numeral 71 denotes a track circuit adjacent to a track circuit including a route forming a step.

Reference numeral 72 designates a turning device included in the track circuit adjacent to the track circuit including the path forming the step.

Reference numeral 73 designates a turning device which simultaneously converts with a turning device included in a track circuit adjacent to a track circuit including a path forming a step.

Reference numeral 74 denotes a track circuit which is adjacent to a track circuit including a path forming a step and which is in contact with the track circuit.

This is a track circuit in which a contact accident occurs when a train vehicle exists at the same time as a train vehicle exists at the walkway.

Reference numeral 75 denotes a track circuit which is adjacent to a track circuit including a path forming a footpath and which violates the contact limit depending on the orientation of the rolling device.

Reference numeral 76 denotes a track circuit which is adjacent to a track circuit including a path forming a step and which does not violate the contact limit.

Although it is not always the case, it is a track circuit in which there is a danger of contact and collision depending on the terrain, train speed and train density.

Although it is allowed to run as a route from the starting point to the finishing point, it is necessary to be prepared for an overrun (the driver intends to stop but cannot stop for some reason). The range "overrun protection zone (taken 150m or more from the past accident experience starting point)" is also defined as "overrun track" according to the track, and is considered in the same way as the normal "track". That is, for the detailed classification of the contents of the route information,
The "track" and the "overrun track" are treated as one without distinction.

FIG. 16 is a classification of the route information extracted from the figure. The number 5 shown in FIG. 9 or 10 is 80 in FIG.
Then, 6 corresponds to 81.

As 80, that is, "indispensable requirements for ensuring the safety of the route", 64, 74, 75, 69 and 70 are grouped. 81, that is, 76, 72, 7 as the “requirements to be sorted out in consideration of safety and efficiency of course”
Group 3, 67 and 68. The "interlocking table" may differ depending on the person, but the main cause is 81
It depends on how to judge and select the item. This part contains the thoughts of a skilled person.

With respect to 76 and 72, the content of the judgment is how wide to secure the range of the course of itself, that is, the range where the other course cannot approach the course of the course. Regarding the risk of contact and collision of train cars, as long as multiple cars exist in a limited area at the same time,
It is almost impossible to defend completely. What kind of situation is assumed and what to do is decided based on experience (cases of past accidents) and sentiment (just in case of the surrounding situation).

With regard to 67 and 68, this tipping device is not used by itself, but if it is possible to take another course depending on the turning direction, that is, if it can be used in another course because it is an empty place without safety problems The decision is to try to increase the train density by using it as much as possible. Even if the train does not run on itself, the turning device in the track circuit in the course keeps the turning direction of the rolling device at the moment the train enters the track circuit. It will be hardened (67 has a Tessa lock). Naturally, the turning direction of the turning device 68 having the same number as that of the turning device 68 is fixed at the same time. If the situation is such that depending on the direction of 68, you can go through another route, do not leave it unprotected, 67,6
It is good to convert with caution before applying the lock at 8.

At 81, candidates to be considered are listed. Whether to adopt the listed candidates,
It is automatically determined by a certain predetermined logic or it is a human judgment. When making a human judgment, an interface is provided to allow it to be accepted.

In the judgment made at 81, whether it is 76, 72 or 68 is a major factor in judging the degree of involvement with another route in the selection. Therefore, as shown by reference numeral 15 in FIG. 12, if a logic for determining the relationship between the routes is provided, the determination at 81 can be performed more quickly and reliably.

[0087]

According to the present invention, as long as the wiring diagram is drawn, the information (track circuit, switch) related to the route, which is the core of the interlocking logic, is automatically extracted.
This frees you from the troublesome and persistent work of stroking the wiring diagram by hand. In addition, the extracted information is classified into those that require human judgment and those that do not require human judgment for adoption / non-adoption, and thus humans can focus on and focus only on judgment. In this way, the extraction and sorting are fully automated, so there is a great labor saving effect in creating and confirming the interlocking table as compared to the case of manually processing everything. The effect goes beyond that. By visualizing the above process, the factors that made the difference in the completion by each person become apparent, and information can be shared among the parties involved in creating the interlocking logic. Therefore, it becomes easier to negotiate and better linkage can be made quickly. It also has the educational effect of making it easier for non-skilled people to pass on the know-how. Further, conventionally, since the wiring schematic and the interlocking table were made separately, it took a lot of time to collate and manage documents, but according to the present invention, the flow from the figure can be unified, so collation and document management can be performed easily. Become.
