Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an equipment layout diagram creating apparatus capable of creating an equipment layout diagram showing a layout state of various types of equipment in a drawing area.

[0002]

2. Description of the Related Art Conventionally, railway companies have created various equipment layout drawings such as a driving track diagram, a station platform facility diagram, and a layout drawing of a driving office and a command room on each station platform. I have.

[0003] Driving track diagrams include, for example, a schematic diagram of track wiring between two stations including a station and a train station, linear conditions necessary for train operation and vehicle replacement, driving safety equipment such as traffic signals and signs, and the like. Operating conditions such as ATC signal presentation are represented by symbols (symbolization), and are widely used in crews and other command and planning businesses. The station platform equipment diagram is a symbolized illustration of equipment necessary for train handling and passenger handling, such as a driving office, a departure course opening indicator, a movement prohibition beacon, and an ITV for train monitoring.

[0004]

By the way, various types of equipment described in the above-described equipment layout are partially rehabilitated (for example, addition of new equipment,
Replacement of old equipment, abolition of old equipment, etc.) are repeated. Information on such equipment repair (hereinafter referred to as equipment information) is registered and managed in forms such as an equipment ledger in accordance with the contents.

On the other hand, with respect to the equipment layout drawing, a great deal of labor and time is required for the work from the creation of the original drawing to the calibration, and it is practically difficult to re-create the equipment layout drawing every time a small repair is performed. . For this reason, at present, the data is re-created every certain period (for example, every five to seven years).
For equipment that has been newly renovated, the latest equipment information is manually added to the equipment layout drawing, and if necessary, the latest form information is also referred to when referring to the equipment layout drawing. We are taking measures such as checking the equipment information of

However, even if the equipment information is manually added to the equipment layout drawing, there is no guarantee that all the equipment information in the form is added, and it is difficult to obtain highly reliable information only from the equipment layout drawing. However, it is difficult to accurately grasp the actual arrangement of the equipment even if the equipment layout is viewed while referring to the forms.

[0007] In particular, when it is desired to know the arrangement state of equipment at a certain time in the past, or the history of equipment repair in the past,
Although it is possible to find a stored past facility layout drawing, it is only assured that the drawing is accurately drawn only when the facility layout drawing is created. Therefore, for example, by specifying specific date conditions that are unrelated to the creation date of the equipment layout drawing, the equipment layout at that time can be grasped from the equipment layout drawing, and the transition per unit day elapsed can be grasped from the equipment layout drawing It was difficult to do.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to create an accurate equipment layout diagram at a desired time as needed even if partial equipment repair has been repeated in the past. An object of the present invention is to provide a possible equipment layout drawing creating apparatus.

[0009]

Means for Solving the Problems and Effects of the Invention According to the present invention, which has been made to achieve the above object, a facility layout diagram showing the layout state of various facilities is drawn as described in claim 1. An equipment layout map creation device that can be created in an area, wherein equipment information storage means for storing equipment information including data indicating the type, arrangement position, and usage period of the equipment, and the equipment information storage Equipment information selecting means for selecting only equipment information whose use period data satisfies a specific time condition from the equipment information stored in the means, and an arrangement in the equipment information selected by the equipment information selecting means A drawing position determining means for determining a drawing position in the drawing area based on the position data; and a drawing position determined by the drawing position determining means, wherein the drawing position is selected by the equipment information selecting means. Characterized by comprising a symbol generator means for generating a symbol corresponding to the type data in the facility information.

[0010] In the facility layout drawing creating apparatus, the facility information storage means is a means in which facility information to be added as needed is written, and the facility information is stored so as to be readable as needed. For example, it is configured using a magnetic disk device or the like.

The equipment information selecting means reads out the equipment information stored in the equipment information storage means, checks whether the use period data in the equipment information data satisfies a specific time condition, and checks the specific equipment information. This is a means for performing data processing for selecting only one, specifically, for example, using a computer. As the specific time condition, a date is normally considered.For example, when a certain date is specified, it is checked whether the date is included in the usage period indicated by the usage period data and included. Only the equipment information determined to be is selected. However, in addition to the date, the above specific time condition may be a month or year, or optionally arbitrarily determined year, first half, second half, etc., and in some cases, various time conditions such as hours, minutes, and seconds may be considered. Conditions can be considered. Further, the usage period data satisfies such a time condition means that the specified time condition is completely included in the usage period and that the specified time condition partially overlaps with the usage period. Such a case is also conceivable.

The drawing position determining means is means for determining a drawing position in the drawing area based on the equipment information selected by the equipment information selecting means. As the drawing area, for example, an area virtually set on a memory, an area on a screen where display is performed by a display device, or an area on a paper surface where recording is performed by a printer or a plotter can be considered. These areas are usually provided with addresses and coordinates, and the drawing position can be determined by converting the arrangement position data into the addresses and coordinates in the equipment information. Such data conversion processing can be realized by a computer.

The symbol generation means is means for generating a specific symbol based on the equipment information selected by the equipment information selection means. The form in which the symbols are generated changes depending on the drawing area. For example, in the case of a memory, forming a bit pattern corresponding to a symbol by combining on / off of bits corresponds to generating a symbol. In the case of a display device, displaying a symbol on a screen corresponds to generating a symbol. In the case of a printer or a plotter, recording a symbol on paper corresponds to generating a symbol. As a specific means for controlling the memory, the display device, the printer, the plotter, and the like, a means configured using a computer can be considered. Regarding the symbols, the relative arrangement and positional relationship of various facilities and the information on each facility are represented by various figures, characters, and symbols, but the specific designs and contents are not limited. Further, it is needless to say that the symbol size and shape may be abstracted different from the actual equipment.

[0014] According to the facility layout drawing creating apparatus configured as described above, the facility information selecting means determines that the use period data in the facility information is a specific time from the facility information stored in the facility information storage means. Only the equipment information that satisfies the objective conditions is selected. Then, based on the selected equipment information, the drawing position determining means determines the drawing position in the drawing area in accordance with the arrangement position data in the equipment information, and the symbol generating means sets the drawing position in the equipment information to the drawing position. A symbol corresponding to the type data is generated.

[0015] Therefore, if equipment information that has been registered and managed in a form and is conventionally stored in equipment information storage means every time equipment is repaired, necessary equipment information can be stored based on the equipment information. A facility layout can be created at any time. In particular, the equipment information stored in the equipment information storage means includes data indicating the period of use, and when the symbol generation means generates a symbol in the drawing area, the equipment information selection means sets a specific time condition. Only matching equipment information is selected. Therefore, instead of being limited to dates such as the creation date of equipment layout drawings and the registration date of equipment information, for example, you can create a facility layout drawing for the current day by specifying a certain date condition in the past, or By specifying conditions, it is possible to create a facility layout drawing so that the process of facility repair can be understood on a yearly basis. That is, even if partial equipment repair has been repeated in the past, an accurate equipment layout diagram at a desired time can be created as needed.

Next, when the equipment layout drawing is created by the equipment layout drawing creating apparatus of the present invention, if a drawing faithfully reproducing the layout including the relative distances between the equipments is to be created, the entire drawing area is to be created. The coordinate system may be set to have a uniform scale over the symbols, and the symbols may be generated according to the coordinate system. However, for example, as in the case of a driving track diagram, there are many facilities around the station, but various facilities are not concentrated between the stations as much as around the station. If the drawing is performed, the symbols are intensively generated only in the vicinity of the station in the drawing area, and there is a problem that the drawing is not always easy to see.

According to a second aspect of the present invention, there is provided a facility layout drawing creating apparatus for generating a sketch in a drawing area representing a reference facility serving as a reference when arranging the facility; Scale setting means for setting a coordinate system necessary for determining the drawing position at a scale defined for each part of the sketch generated by the generating means, wherein the drawing position determining means sets the scale setting. The drawing position is determined according to a coordinate system set by the means.

According to such a facility layout drawing creating apparatus,
The coordinate system required for the scale setting means to determine the drawing position is set on the scale defined for each part of the sketch generated by the sketch generating means. Therefore, if the drawing position determining means determines the drawing position in accordance with the coordinate system set by the scale setting means, the symbols generated by the symbol generating means will be dispersedly arranged according to the draft, It is possible to create a facility layout diagram that is easier to see.

Therefore, for example, as shown in the above-mentioned operation track diagram, there are many facilities around the station, but if various facilities are not concentrated between the stations as much as around the station, the station must be Prepare a layout drawing of the track with the periphery enlarged as a draft. Then, the scaled-up coordinates are defined in advance for the area drawn for the vicinity of the station, while the scaled-down coordinates are defined for the area drawn for the stations. This makes it possible to obtain a very easy-to-see driving track diagram.

It is to be noted that both the sketch generating means and the scale setting means may be configured as a specific means using, for example, a computer. The sketch generated by the sketch generating means is a picture generated by generating various line segments and graphics based on a data sequence representing the type of the graphic and the coordinates in the drawing area, similarly to the symbol generated by the symbol generating means. I just need. Further, the image may be a picture in which pattern data optically read by an image scanner or the like is developed as it is in a drawing area.

By the way, when the sketch generation means as described above is adopted, the equipment layout is composed of sketches and symbols, but there is a possibility that the reference equipment represented by the sketches will also be modified. There is a case where the form changes. Therefore, in order to cope with such a change in the reference equipment, for example, from among the equipment information stored in the equipment information storage means, the reference equipment which selects the equipment information of the reference equipment to be generated as a sketch by the sketch generation means is selected. Based on the equipment information selected by the information selection means and the reference equipment information selection means, the time condition not included in the use period of the reference equipment is the specific condition which is a selection criterion by the equipment information selection means. It is preferable to provide a warning unit that warns that there is an error in the specific time condition when the time condition is satisfied.

In such a configuration, the reference equipment information selecting means and the warning means perform a consistency check between the service period of the reference equipment drawn in the sketch and the service life of the symbolized equipment. This is a means for issuing a warning in the case of inconsistency. More specifically, for example, it is configured using a computer and issues a warning by screen display or sound. This way,
When a temporal condition that is not included in the use period of the reference facility is a specific temporal condition that is a selection criterion by the facility information selecting unit, the warning unit has an error in the specific temporal condition. Therefore, it is possible to prevent a sketch and a symbol that cannot be present at the same time from being simultaneously drawn.

Next, the arrangement position data in the equipment information is data indicating the actual arrangement position of the equipment, and is not data in consideration of the layout on the equipment layout drawing. Therefore, when two or more facilities exist at the same arrangement position or very close arrangement positions, the drawing position determination means simply determines the drawing position in the drawing area according to the arrangement position data in the equipment information. There may be a case where two or more symbols overlap due to the arrangement position data. In such a state, for example, there is a possibility that all the symbols are seen in the overlapping state and the shape of the symbols becomes unclear, or a problem that only the uppermost overlapping symbol is seen.

In order to solve such a problem, the equipment layout drawing apparatus according to the present invention is arranged such that two or more symbols overlap with the drawing position determined by the drawing position determining means due to the layout position data. A drawing position correcting means for shifting the drawing position to a position where the symbols do not overlap.

According to such a facility layout drawing creating apparatus,
When two or more symbols overlap, the drawing position correction unit shifts the drawing position to a position where the symbols do not overlap. Therefore, the symbol generated at the corrected drawing position does not cause such a problem that the shape of the symbol becomes unclear as described above or that only the symbol overlapping the uppermost part is seen.

The method of shifting the drawing position is not particularly limited. However, since the size of each symbol is usually known in advance for each symbol, the size of each overlapping symbol is taken into consideration and another symbol is taken into account. The drawing position may be shifted to a nonexistent area.
If the shift amount of the drawing position is determined based on the largest symbol, the drawing position can be shifted without having to judge the size of the symbol.

Next, the equipment layout diagram creating apparatus configured as described above can create the arrangement state of various facilities. Particularly, when creating a railroad operation track diagram, it is described in claim 4. Like the equipment layout diagram creation device,
The sketch generation means generates a sketch representing a railway line, and the symbol generation means generates a first symbol group to be generated by overlapping on the sketch line, and does not overlap on the sketch line. Preferably, a second symbol group to be generated is generated.

According to such a facility layout drawing creating apparatus,
This is useful for creating railway tracks, especially for railways.
The equipment arranged on the track and the equipment arranged on the side of the track can be plotted by dividing them by the first and second symbol groups. In particular, when two or more symbols overlap with the drawing position determined by the drawing position determining means due to the layout position data as in the equipment layout drawing creating apparatus according to claim 5, Drawing position correcting means for shifting the drawing position to a position where symbols do not overlap, wherein the drawing position correcting means shifts the drawing position in a direction along the route for the first symbol group; Regarding the second symbol group, if the drawing position is shifted in a direction away from the route, even if the drawing position is shifted, the equipment arranged on the track is , The symbols will be generated by overlapping on the sketch line, while for the equipment located beside the track, the symbols will be emitted without overlapping on the sketch line. It means to be, it is possible to create a line diagram closer to actual conditions. In addition, when checking facilities while following a route in the drawing area, there is no possibility of accidentally overlooking equipment on the track or causing unexpected equipment on the track to make it difficult to see the figure. .

Next, the equipment layout drawing apparatus described above can be developed and operated as a dedicated apparatus having the above functions. A storage medium recording a facility layout drawing creation processing program for creating a facility layout drawing in which a state is represented in a drawing area, and includes data indicating a type, a placement position, and a use period of the facility. Equipment information reading means for reading the equipment information from equipment information storage means for storing the obtained equipment information, and selecting only the equipment information whose use period data satisfies a specific time condition from the read equipment information. Processing, a drawing position determining process for determining a drawing position in the drawing area based on the arrangement position data in the equipment information selected by the equipment information selecting process, and the drawing position Making the computer execute a symbol generation process for generating a symbol corresponding to the type data in the facility information selected by the facility information selection process at the drawing position determined by the fixed process, If there is a recording medium on which the processing program is recorded, a general-purpose computer system can read the facility layout drawing creation processing program from the recording medium without necessarily configuring a dedicated facility layout drawing creating apparatus, and can therefore make a claim. Functions equivalent to those of the facility layout drawing creating apparatus described in Item 1 can be realized on a general-purpose computer system.

The recording medium may be a computer-readable recording medium such as a magnetically readable recording medium (eg, a magnetic tape, a flexible disk, etc.) or an optically readable recording medium (eg, an optical disk, a magneto-optical disk, etc.). -A well-known recording medium which can read the recorded content by the system can be arbitrarily adopted.

The following first to fourth modified examples of the recording medium storing the facility layout drawing creation program according to claim 6 can be considered. The first modification is
7. A recording medium on which the facility layout drawing creation program according to claim 6 is recorded, wherein at least before the execution of the drawing position determination processing, a draft representing a reference facility for arranging the facility is drawn in the drawing area. A sketch generation process to be generated, and a scale setting process for setting a coordinate system required to determine the drawing position at a scale defined for each portion of the sketch generated in the sketch generation process to the computer. A storage medium storing a facility layout drawing creation processing program, wherein the drawing position determination processing is performed to determine the drawing position according to the coordinate system set in the scale setting processing.

This makes it possible to realize, on the above-mentioned computer system, functions equivalent to those of the facility layout drawing creating apparatus according to the second aspect. According to a second modification, in a recording medium storing a facility layout drawing creation program according to claim 6 or the first modification, the drawing position determined by the drawing position determination processing is added to the convenience of the layout position data. Recording two or more equipment layout drawing creation processing programs, wherein, when two or more symbols overlap, the computer executes a drawing position correction process of shifting the drawing position to a position where the symbols do not overlap. Medium.

This makes it possible to realize, on the computer system, functions equivalent to those of the facility layout drawing creating apparatus according to the third aspect. In a third modification, a sketch representing a railway line is generated in the sketch generation process on a recording medium that records the facility layout drawing creation program described as the first variation, and the symbol generation process includes A facility layout drawing creation program for generating a first symbol group to be generated on the sketch line and a second symbol group to be generated without overlapping on the sketch line is recorded. Recording medium.

This makes it possible to realize, on the computer system, functions equivalent to those of the facility layout drawing creating apparatus according to the fourth aspect. A fourth modified example is that, in a recording medium on which a facility layout drawing creation program described as a third modified example is recorded, two or more drawing positions determined by the drawing position determination processing process are added due to the layout position data. In the case where symbols overlap, the computer causes the computer to execute a drawing position correction process of shifting the drawing position to a position where the symbols do not overlap, and in the drawing position correction process, the The drawing position is shifted in a direction along the line, while the drawing position of the second symbol group is shifted in a direction away from the route. recoding media.

This makes it possible to realize, on the above-mentioned computer system, functions equivalent to those of the facility layout drawing creating apparatus according to the fifth aspect.

[0036]

Next, an embodiment of the present invention will be described with reference to an example. As shown in FIG. 1, a facility layout drawing creating apparatus 1 shown as one embodiment of the present invention is a facility layout drawing used by a railway company, specifically, a driving track diagram, a station platform facility drawing, and a driving office layout. It can create diagrams and the like.

The equipment layout drawing making apparatus 1 is configured using a computer system constructed by arranging various peripheral devices around a computer main body 2. As the peripheral devices, a display device 3 capable of displaying arbitrary characters and figures, a keyboard 4 capable of inputting arbitrary characters and various instructions by key operations, and a mouse 5 capable of specifying an arbitrary position on the screen of the display device 3 A magnetic disk device 6 which stores a processing program and various data, and which can arbitrarily read the stored data from the computer main body 2;
An image scanner 7 that optically reads figures and tables and converts them into image data, a printer 8 that can print figures and tables on recording paper, and a magnetic tape device 9 that can input and output magnetic tapes that are exchangeable recording media, etc. These are all connected to the computer main body 2.

The equipment layout drawing creating apparatus 1 configured as described above reads out various processing programs stored in the magnetic disk device 6 onto a memory built in the computer main body 2 and executes the same in the computer main body 2. .
The various processing programs are usually provided in a state of being recorded on a magnetic tape as a recording medium, read out by using the magnetic tape device 9 before execution, and stored in the magnetic disk device 6. .

Next, a description will be given based on the equipment information input processing and the equipment layout drawing creation processing executed in the equipment layout drawing creating apparatus 1. The equipment information input processing and the equipment layout drawing creation processing are executed by selecting an item representing each processing from various functions listed in a menu format as an initial screen on the screen of the display device 3.

The facility information input process described above is a process of additionally registering information on the various facilities in the facility information file in the magnetic disk device 6 every time the various facilities are modified. As shown in FIG. 2, when the facility information input process is started, the computer main body 2 first displays a list of facility types that can be registered in the facility information file as facility information on the screen of the display device 3 and registers the list. It waits until the type of equipment to be specified is specified (S102). The types of equipment information displayed in a list can be broadly classified into those used exclusively for driving track diagrams, station platform equipment diagrams, and operation office layout diagrams, or two of the above three types. Some are commonly used by more than one species. In addition, there are two types of equipment: a reference equipment drawn as a sketch in the equipment layout drawing creation processing described later, and equipment other than the reference equipment. For example, in the case of facility information used in a driving track diagram, typical examples of reference facilities include a track, a platform, and the like. On the other hand, facilities other than the reference facilities can be classified into facilities that are superimposed on the track and those that are not superimposed on the track in the railway diagram.Typical examples of the former are tunnels and those of the latter. A typical example is a ground signal. It should be noted that there are several tens of types in addition to the above representative examples. However, since the specific contents of these types are not the main part of the present invention, they are limited to the above examples.

Here, the user performs an input operation for designating the type of equipment to be registered among the types displayed in the list.
Incidentally, as the input operation, specifically, an operation of placing a mouse cursor on a predetermined item on the screen and clicking a button of the mouse 5 or an operation of pressing a predetermined key on the keyboard 4 can be considered. In the description above, it is simply referred to as “performing an input operation”.

When the type is specified in the process of S102, the input items determined according to the type are displayed in a list on the screen of the display device 3, and the process waits until necessary input items are input (S104). ). Although the input items differ depending on the type of equipment, input items for inputting at least information corresponding to the arrangement position of the equipment and the usage period are always included regardless of the type of equipment. More specifically, in the case of facility information used for creating a driving track diagram, the present apparatus uses information corresponding to the location of the facility as a kilometer (based on the departure station at the end of the track, The location of the equipment is the distance along the track from the departure station), the type of up / down line, the number of the line, etc. As the use period, a use start date and a use end date can be input. However, the end date of use need not be entered if the corresponding facility is in operation.

Here, the user performs a data input operation for necessary input items, and then performs an input operation for instructing completion of the input. After the input operation, various error checks are performed to determine whether or not the input information includes unauthorized information as facility information, and processing such as prompting re-input is performed as necessary. However, these specific processes can vary depending on the type of equipment, the degree of importance, and the like, and are not a main part of the present invention.

When the processing of S104 is completed, the computer main body 2 additionally registers the input equipment information in the equipment information file in the magnetic disk device 6 (S10).
6). By the above-described facility information input processing, facility information is accumulated in the facility information file. The equipment information stored in the equipment information file is also used as data for drawing in the equipment layout drawing creation processing described later, but is basically information for equipment management,
It is used in a form such as printing in a form that can be stored in various forms, or displaying and browsing the content on the screen of the display device 3.

The equipment layout drawing creation processing described below is processing for creating a equipment layout drawing based on the equipment information in the equipment information file. This equipment layout drawing creation processing is processing for creating any of a driving track map, a station platform equipment drawing, and a driving office layout drawing. Which of these is to be created is individually displayed among various functions listed in a menu format as an initial screen on the screen of the display device 3, so that when an item corresponding to the creation target is selected, , Which figure to create. However, the basic processing flow is
The same is true for all figures, so in the following description
The description will be made on the assumption that a driving track diagram is created.

As shown in FIG. 3, when the facility layout drawing creation process is started, the computer main body 2 first reads out the stored outline information on the sketch from the magnetic disk device 6 (S202). The summary information includes heading data given when the sketch is saved, place data drawn in the sketch, use start date data of the equipment (reference equipment) drawn in the sketch. The computer main body 2 displays these items in a list on the screen of the display device 3 and waits until a sketch is designated (S204).

Here, the user determines a necessary sketch from the information displayed in the list, and performs an input operation for selecting a specific sketch. If the required sketch does not exist, an input operation for instructing the creation of a new sketch can be performed. However, here, the description will be continued assuming that the necessary sketch exists.

In the process of S204, when a specific sketch is selected, the sketch data, which is the substance of the sketch, is read from the magnetic disk device 6 (S206). Here, the sketch data read from the magnetic disk device 6 is, for example, C
This is a data string representing the type of graphic and the coordinates in the drawing area, such as that handled by AD, or pattern data optically read by an image scanner or the like.

Then, the scale information set for the selected sketch is read from the magnetic disk device 6 (S20).
8). Here, the scale information read from the magnetic disk device 6 is data indicating which range of the sketch is represented at what scale. Note that the scale information is data set arbitrarily by the user for each part of the sketch after the creation of the sketch, and there is a case where the uniform scale is set for the whole sketch, but only the part of the sketch is the same as the remaining part. May be set to a different scale.

After reading out these data,
A draft is generated in the drawing area (S210). S210
The specific processing changes according to the format of the read data. For example, when a data string representing the type of a figure and the coordinates in the drawing area is read, various line segments are read based on the data string. And a process of generating a graphic. If the data is optically read pattern data, the pattern data is developed in a drawing area in a predetermined procedure. Also, based on the scale information, a scale is drawn at the lowest position of the drawing area in units of kilometers to indicate the scale in the horizontal direction as a part of the sketch. The scale set for the sketch can be known by referring to the scale in the drawing area.

In the process of S210, a process of generating a sketch on the screen of the display device 3 is performed.
However, this processing is, strictly speaking, the computer main body 2
This is a process for generating a bit pattern corresponding to a sketch in a drawing area virtually set on a built-in graphic display memory. Then, the bit pattern (draft) created in the drawing area on the graphic display memory is displayed in the drawing area set on the screen of the display device 3 by a standard function of the computer main body 2. Incidentally, the sketch displayed on the screen of the display device 3 is such that, for example, as shown in FIG. 4, the arrangement of the tracks around the station is drawn in the upper area A1, and in the lower area A2,
This is a diagram in which a scale indicating a horizontal scale is drawn.

After the process of S210 is completed, a screen for designating symbol generation conditions is displayed, and the process waits until symbol generation conditions are designated (S212). Here, the user sets the symbol generation conditions as date conditions,
Perform an input operation to specify the placement position condition, type condition, and the like. The date condition is a condition for selecting only equipment that was in use on the designated date (year, month, day, hour, minute) as a drawing target. The date that can be specified here is at least a date within a period during which the reference equipment drawn as a sketch is in use, and a date outside this period is treated as an error processing target. The layout position condition is a condition for selecting only equipment that should be drawn in a certain area on the sketch as a drawing target. In the case of a driving track diagram, by specifying a kilometer, the horizontal range within the drawing area For, the drawing target range can be limited. The type condition is a condition for selecting only equipment of a desired type (a plurality of types can be specified) from all the equipments as a drawing target.

When the conditions are specified in the process of S212, the facility information is read from the facility information file in the magnetic disk device 6 (S214). Then, it is checked whether or not the equipment information is necessary equipment information, that is, whether or not the date condition, the arrangement position condition, and the type condition are all satisfied (S216).

Here, when all the above conditions are satisfied, it is determined that the information is necessary equipment information (S216: YE).
S) In this case, based on the scale information read out in S208, the arrangement position data in the facility information is converted into a drawing position in the drawing area (S218). Then, a symbol corresponding to the type data in the equipment information is generated at the drawing position in the drawing area (S220). The symbol to be generated here has a design determined in advance according to the type data, and the design and a variable portion such as a character added to the design are stored in a predetermined position on the memory as a bit image.

In the case of this apparatus, the drawing area for one drawing is 25.
The figure, which is divided into six layers and is obtained by superimposing symbols and sketches generated on each layer, is displayed as a figure drawn in the drawing area. The symbols generated in the process of S220 are drawn in a memory corresponding to a layer different from the sketch described above, and each symbol is also drawn in a memory corresponding to a different layer according to the type data. In displaying the drawing area, display / non-display of each of these layers can be arbitrarily switched individually for each layer. Similarly, when printing, printing / non-printing of each layer can be individually designated.

When the processing of S220 is completed in this way, or when it is determined in the processing of S216 that the information is not necessary equipment information (S216: NO), the processing proceeds to S2.
Returning to the process of 14, the processes of S214 to S220 are repeated until all the equipment information is processed. Then, when the end of the equipment information file is detected in the processing of S214 (S214: EOF), this processing ends.

By the equipment layout drawing creation processing described above,
On the screen of the display device 3, a driving track diagram as illustrated in FIG. 5 is displayed. This driving track diagram is a diagram in which symbols representing various facilities are superimposed and displayed on the sketch shown in FIG. In particular, since a specific date condition is specified and the equipment information is selected based on whether the date condition is satisfied, the arrangement of the equipment on the specified date is accurately represented. Therefore, if this device is used,
Even if a partial repair of the track and the equipment around the track has been repeated in the past, it is possible to create an accurate operation track diagram at a desired time at any time.

The operating line diagram created by the facility layout drawing creating process can be printed out to the printer 8 by a standard function of the computer main body 2.
Further, the completed operation track diagram itself can be stored in the magnetic disk device 6 as it is. In this case, if necessary, the saved operation track diagram is copied to the magnetic disk drive 6.
The driving line diagram thus read out can be displayed on the screen of the display device 3 or the printer 8.
It can also be printed out.

By the way, in the equipment layout drawing creation processing described above, the drawing position of the symbol is determined based on the layout position data in the equipment information. However, two or more facilities are located at the same layout position or very close layout positions. If they exist, two or more symbols may overlap. In such a state, the symbols drawn on the uppermost layer become invisible, and the symbols drawn on the lower layer become invisible.

Therefore, in order to eliminate such symbol overlap, the present apparatus is configured to execute the drawing position correction processing shown in FIG. When the drawing position correction processing is started, the computer main body 2 checks whether or not two symbols A and B occurring at the overlapping position exist (S302), and if they do not exist (S302:
NO), this process ends as it is.

On the other hand, when there are two symbols A and B occurring at the overlapping position (S302: YES), a symbol having a lower priority order is selected from the symbols A and B as a correction target (S304). ). This priority is determined in advance for each symbol, and the description will be continued here assuming that the priority of the symbol B is low.

Subsequently, it is checked whether or not the symbol B selected in the processing of S304 is to be generated by overlapping on the route drawn as a sketch (S30).
6). If it should be generated on the route (S30
6: YES), the drawing position of the symbol B is shifted by an amount corresponding to the size of the symbol A along the extending direction of the route (S308). More specifically, for example, as shown in FIG. 7A, a symbol A drawn in a rectangular area of size a × b and a symbol B drawn in a rectangular area of size c × d
Are both drawn at the drawing position P1 (e, f) on the route C, the size a of the symbol A is added to the coordinate e to shift the drawing position of the symbol B in the extending direction of the route C, and the symbol B Is shifted to the drawing position P2 (e + a, f). As a result, as shown in FIG. 7B, the overlap between the symbols A and B is eliminated.

On the other hand, if the symbol is not a symbol to be generated on the route (S306: NO), the drawing position of the symbol B is shifted in a direction away from the route by an amount corresponding to the size of the symbol A (S310). More specifically, for example, as shown in FIG. 7C, a symbol A drawn in a rectangular area of size a × b and a symbol B drawn in a rectangular area of size c × d are both near the route C. Is drawn at the drawing position Q1 (g, h), the size b of the symbol A is added to the coordinate h so as to shift the drawing position of the symbol B away from the route C, and the symbol B is drawn at the drawing position Q2 ( g, h + b). As a result,
As shown in FIG. 7D, the overlap between the symbols A and B is eliminated.

When the processing of S308 or S310 is completed, the symbol B drawn at the drawing position before correction in the drawing area is deleted (S312), and a new symbol B is generated at the corrected drawing position. (S314). The overlapping of the two symbols is eliminated by the drawing position correction processing described above. In particular, even if the drawing position of the symbol is shifted, the equipment on the track is drawn on the track and the equipment outside the track is drawn outside the track, so it is erroneous whether the equipment is on the track or outside the track. There is no. Also, for equipment outside the track, the coordinates in the direction along the track do not change,
It can be accurately grasped that the equipment exists at the same position.

The drawing position correcting process may be executed by designating a specific symbol by the user, or may be performed for all symbols.
May be automatically and repeatedly executed. Also,
When a large number of symbols are to be processed in the drawing position correction processing, there is a high possibility that the corrected drawing position overlaps the drawing position of another symbol. So, in that case,
Whenever a new drawing position is calculated, check whether a new overlap occurs.If a new overlap occurs, take measures such as further increasing the shift amount or changing the shift direction. To calculate the drawing position again.

Although the embodiments of the present invention have been described above, various specific embodiments other than those described above are conceivable for the embodiments of the present invention. For example, in the above description,
As a specific example of the equipment layout diagram, each process has been described while exemplifying an operation track diagram.However, according to the equipment layout creation device of the present invention, even for a facility layout diagram other than the operation track diagram, It can be created by the same procedure. More specifically, various equipment layout drawings such as station platform equipment drawings and layout drawings of a driving office and a command room on each station platform can be created. Also, by recording and accumulating the equipment information for each of the various equipment arrangement drawings, the equipment arrangement drawing at a desired time can be arbitrarily created later.

By the way, the task of creating a driving line diagram by printing and storing the printed matter as in the prior art is simply systematized and realized by a computer system, that is, a computer system at an appropriate time. Even with a system that creates a driving track diagram and stores it in the auxiliary storage device, the work of searching for the required driving track diagram by looking at the form later can be performed using a computer, so that the work can be speeded up. You can do it.

However, such a system is merely a computerized management of a driving track diagram, and a driving track diagram close to a desired one is selected from a large number of driving track diagrams created on a specific date. You can only select figures. On the other hand, in the present invention, since the information on the equipment is made into a database, the equipment information is selected on a desired date condition, and the operation line diagram is created based on the selected equipment information, the equipment information is registered. It is possible to designate a specific date irrespective of the date, and to create an operation track diagram in which the equipment arrangement as of that date is accurately represented at any time.
