Here, the process caused by selecting the region 211 to the region 217 is referred to as “moving process” in the specification.
Say

Next, the operation procedure of the route designation and the accompanying transition of the display contents on the screen will be described.

FIG. 3 shows an example of a route information input start screen. This screen is the initial screen shown in FIG. 2. First, the zoom level control area 209 is operated to generate a designated frame of a size corresponding to the zoom level on the entire map displayed in the area 204. Move the designated frame with the mouse and position it in the desired area. When the mouse is instructed to end the positioning operation of the designated frame, the route map of the map area in the designated frame appears on the screen instead of the entire map as shown in FIG. The display content on the screen can be changed by operating the scroll button 208.

In this example, the route map includes station names, station marks,
It consists of a line segment showing the route. Station names are code A to Q
The station mark is represented by a white circle. The display of the station mark is, for example, a station designated as a boarding station, an alighting station, or the like, or an expression format is appropriately changed so that a specific station can be distinguished from other stations, and an operator can select a route, or Make it easy to understand the input status of route information. In addition, the lines are curves 301 and 30 that connect stations.
2, 303, 304 and 305 are displayed. The route may be expressed by a method of connecting the stations with a straight line in order to improve the drawing speed. In the present embodiment, the display format of the line segment indicating the route is changed depending on the type of the route and the selected state, so that the operator can easily grasp the work situation.

When the station J is selected by the input device 5 in the route display area 204 shown in FIG. 3, the screen changes to the state shown in FIG. The pointing for selecting a station may be a station mark or a station name. In this example,
The station first designated by the operator on the route map is controlled so as to be automatically treated as the "boarding station". For example, by selecting the boarding station name display area 201, the input mode is changed to "boarding station input mode". After that, the first input station may be treated as the boarding station. According to the latter method, although the number of operations increases, the input items can be determined by the operator's will. Therefore, depending on the operator's convenience, the getting-off station name display area 202 can be selected first, and the getting-off station can be designated before getting on You can also specify the station.

In FIG. 4, the selected station mark J is
The display mode (filled triangle) showing the boarding station has changed. At this time, routes that can be boarded from station J, that is, route 301 and route 304 are displayed in the form of lines that can be selected from the thin solid lines that indicate the normal state (hereinafter referred to as “branch line”).
Change to a thin broken line. Control of display contents and status of stations / routes on these screens will be described later in detail. When the display screen changes to the above state, routes other than the branch routes 301 and 304, for example, routes 302 and 3
The input operation for selecting 03 or 305 becomes invalid.

Assuming that the operator selects the route 301 from the branch routes, as shown in FIG. 5, the name of the route 301 is displayed in the display area 203 indicating "the route of interest", and the route map is displayed. The route 301 is changed to a display form (thick broken line) that can be distinguished from other routes. In addition, the above route 301
Lines 305 and 305, which can be changed at stations other than the boarding station J, are set as new branch lines, and the display form of these branch lines changes from thin solid lines to thin broken lines. To do. On the other hand, route 30 that was not selected
4 returns from the display form of the branch line (thin broken line) to the display form of the normal line (thin solid line).

Next, assuming that the operator has designated the station P on the branch line 305, the designated station P is treated as the "departure station" and the screen transits to the "route confirmation screen" shown in FIG. On the route confirmation screen, the station mark indicating the station P is changed to a display mode (filled rectangle) indicating the exit station. Also,
A display form in which the section from the station J on the line 301 to the station M which is the transfer station to the line O and the section from the station M on the line 305 to the station P which is the alighting station show the "fixed line" (thick solid line ) Has changed.

The control method for realizing the above-mentioned screen change will be described below.

FIG. 7 shows a schematic processing flowchart of the control program executed by the terminal device 1. This control program consists of the following processing steps 701 to 707.

The present invention is characterized by the control when specifying a physically and logically continuous path, but the above processing flowchart shows the flow of processing of the entire system. Here, an example of application to a system that centrally manages requests from the terminal 1 by the central device 11 is shown. In particular, in order to specifically show a route, an example of application to a system that sells train tickets is taken as an example. The following will be explained.

Process 701: As pre-process, information other than route information is input. Specifically, it is information such as whether or not the passenger seat is a non-smoking car, whether it is a round-trip ticket, and how many tickets are required. In this processing, the boarding station or part of the route may be input. Process 702: Input a route. This is a part that executes a characteristic function of the present invention, and details thereof will be described later with reference to FIG. Step 703: Convert the routing information into an information format to be transmitted to the central unit (center) 11. Process 704: The generated electronic message is transmitted to the central center. Process 705: Waiting for a response from the central center 11 to the transmitted electronic message. If there is a response, the process proceeds to process 706. Process 706: The corresponding process is executed based on the response information from the central center 11. For example, ticket printing, ticketing processing, and the like. Process 707: If the next process is to be executed, the process returns to process 801.

In the above flowchart, the process 70
1. The implementation method of processing 703 to processing 707 is not specified. Further, the processing 701 and the processing 702 are non-procedural, and it is possible to transit to mutual processing in the middle.

Details of the route input process 702 will be described below with reference to the flowchart shown in FIG. The execution program of this processing flow is the route input program 14,
The activation is performed by the route input activation means 16, and when this is activated, the route map is displayed on the CRT, and the route can be input. This program consists of the following processing steps.

Process 801: Waiting for input from the operator. Process 802: Based on the coordinate information from the input device 5 designated by the operator, it is determined which one of the regions on the CRT 2 has been selected. Process 803: It is determined whether or not the information input in process 802 specifies a valid area. If the designated area is the “confirm button” 206 or the “cancel button” 207, the processing proceeds to step 809. If the designated area is other than the valid area, the processing proceeds to step 804. If there is no valid area corresponding to the designated area, the processing proceeds to step 808. ..

Process 804: It is determined whether or not the designated area is the route diagram area. In the case of the route map area, the processing proceeds to step 805, and in the other areas, the processing proceeds to step 806. Process 805: A route input process is performed. After the processing is completed, the processing proceeds to processing 807. Process 806: Perform a process corresponding to each area. Details of the processing content will be described with reference to FIG. Process 807: Update the contents displayed on the screen according to the input information. Details of the processing content will be described later with reference to FIG. Process 808: Notify that the specified area is invalid. Examples of the notification method include output of a caution sound or screen display of a message. When this is done,
The state transits to the input waiting state 801 again. Process 809: Input the determined route into the input information analysis program 1
Then, the route input process is terminated. At this time, a process for eliminating duplicated information of the decided route is performed.

FIG. 9 shows the structure of the data file used in this embodiment. The data file is usually stored in the storage medium 9 and is expanded in the MM 4 according to the processing content of the CPU 8. The data file includes a drawing route table 901 that holds information about routes, a drawing station table 902 that holds information about stations, and a branch route table 903 that shows the connection relationship between routes.

The drawn route table 901 is a route name 904 indicating the name of a route, a display level 905 indicating the zoom level at which the route is displayed, the number of entries 906 indicating the number of stations belonging to the route, and the station on the route is a drawing station table. It is composed of a station index 907 indicating which record of 902 starts.

The drawing station table 902 is composed of a station name 908, a station display level 909 indicating a zoom level at which the station is displayed, and a station coordinate 910 indicating coordinates displayed by the station, for each station in the route to be drawn. .. Here, station coordinates 910
For the coordinate values of, the coordinate system that is centrally managed in the entire route map is used. In the present embodiment, since the route is expressed by a straight line, the line can be drawn by connecting the adjacent coordinate information managed here with a straight line. Further, by arranging adjacent stations in a continuous record, it is possible to improve the drawing performance and reduce the data capacity by not holding the adjacent information of the sense of station.

The branch route table 903 has a route name 91.
1, a station name 912 indicating the name of a station connected to another line, and a branch line name 913 indicating the name of the connected line.

Reference numeral 914 is a route table for storing the input route, which is the route name 915, the route display level 916, the station name 917, the station coordinates 918, and the station display level 91.
It is composed of 9. This table is updated every time a route is specified. For example, the record structure in the route table 914 is such that the boarding station is a station on line A, the transit station is b1 station where line A and line B intersect, and the getting-off station is b2 station on line B. Is shown.

FIG. 10 shows the station / route drawing processing 80 described above.
7 shows a detailed flowchart of No. 7, which comprises the following processing steps.

Process 1001: The control variable i is initialized to 1. Process 1002: It is determined whether the route i is a drawing target. The criterion for judgment is that the current display level is the route display level 905.
In the above cases, it is determined to be the drawing target, and in other cases, it is determined that the drawing target is not the drawing target. When drawing, processing 100
If no drawing is performed, the process proceeds to step 1010. Process 1003: The route i is designated to be drawn. Process 1004: The control variable j is initialized to 1.

Process 1005: The station j on the line i is drawn and determined. As a criterion for determination, if the current display level is equal to or higher than the route display level 909, it is determined to be a drawing target, and in other cases, it is determined not to be a drawing target. If it is a drawing station, process 10
If the drawing station is not 06, the process proceeds to step 1007. Process 1006: Station j is drawn and designated. Process 1007: The station j is designated not to be drawn. Process 1008: It is checked whether or not all stations on the route i have been processed, and if the process is not completed, the process 100
9. If completed, go to processing 1010. Process 1009: Increase j by 1.

Process 1010: It is determined whether or not all routes have been processed, and if the process has been completed, process 1012.
If not, the process proceeds to process 1011. 9 Process 1011: Increase i by 1. 9 Process 1012: The coordinate conversion process of the drawing object is executed.
Details of this processing will be described later.

FIG. 11 shows the relationship between the route map display area 204 and the corresponding partial area (route map projection area) 1102 in the entire route map area 1101. In the present invention, the route information is set so that it is easy to understand the positional relationship of each element.
One feature is that it is expressed on a dimensional plane. In this case, all route information is managed by unified coordinates so that the degree of detail of the route map displayed in a fixed area on the screen and the position and range of the partial area to be displayed can be arbitrarily adjusted.
This method divides the route map into a plurality of areas and manages independent coordinate systems. (1) Since the areas are not divided, it is not necessary to be aware of the boundaries of the areas. Also, an arbitrary rectangular area in the entire route map can be displayed. When the route map is divided and managed in a plurality of coordinate systems, the process is simpler than that in which the coordinates of both regions need to be corrected and displayed in order to display a rectangle containing the divided regions. ..

(2) It can be displayed on the screen by enlarging or reducing it to any magnification.

(3) Since the route map coordinate management information is unified when the route data is updated, it is impossible to have the route information redundantly. Therefore, the number of correction points can always correspond to the number of correction items.

There are advantages such as

In the example shown in FIG. 11, the entire route map drawing area is all over Japan. In this case, the origin of the centralized coordinates national, and the upper left point R ₀ of expanded plane (0,0), the point R _e in the lower right coordinates (Rxmax, Rymax). Hereinafter, this coordinate system is referred to as "nationwide centralized coordinate system". In this, the position and range of the route map projection area 1102 are adjusted according to the input request from the operator, and the contents to be expanded in the route map drawing area 204 on the CRT are controlled. The parameter to control is the point Q (R
x0, Ry0) and the area sizes RLx, RLy of the route map projection area 1102.

The coordinates of the upper left point Q (Rx0, Ry
0) is the coordinate value of the national unified coordinate system. This area is expanded in the route map display area 204. Therefore, the point D ₀ (Dx0, Dy0) at the upper left of the route map display area 204 is Q (Rx0, Ry0) in the national unified coordinate system, and the point D _e (Dxmax, Dymax) at the lower right is the route map projection area. The lower right point of 1102 (Rx0 + RLx, Ry0 + RL
y) corresponds. Therefore, the position (Rx, Ry) of the national unified coordinate system corresponding to the input coordinates (Dx, Dy) of the route map display area input by the operator uses the width and height DLx, DLy of the route map drawing area 204. It is expressed by the following formula.

Rx = Rx0 + (Dx−Dx0) / (Dxmax−Dx0) × RLx Ry = Ry0 + (Dy−Dy0) / (Dymax−Dy0) × RLy ... Equation 1 The station disease described above is held in the file 902. Station coordinates 91
0 is the value of the nationally unified coordinates, and the coordinate conversion in the process 1012 follows the formula 1.

FIG. 12 shows the table required for the coordinate conversion processing.

The coordinate management table 1201 is a table for managing the position of the route map projection area 1102 in the national unified coordinate system. The coordinate management table 1201 stores the x-direction component Rx of the upper left coordinate Q ₀ of the route map projection area 1102.
0 (1202), y-direction component Ry0 (1203), the width RLx (1204) of the area of the route map projection area 1102, the height RLy (1205), and the movement amount Sx (12) during scrolling.
06) and Sy (1207). The route map projection area 1102 has Rx0 (1202) and Ry0 (1
203), RLx (1204) and RLy (1205). Here, RLx (120
4) and RLy (1205) change depending on the zoom level.

The variable management table 1208 includes Rx0 (1202), Ry0 (1203) and RL for each zoom level.
x (1204), RLy (1205), Sx (120
6) and Sy (1207) are stored, ZRx0 (120
9), ZRy0 (1210), ZRLx (1211),
ZRLy (1212), ZSx (1213), ZSy
(1214).

Next, the route input processing 805 of FIG. 8 will be specifically described with reference to FIGS. 13 and 14. Here, update control for the route or station designated by the operator is taken as an example. When an input operation is performed by the operator, if the selection area determined in the input information analysis processing 802 is “station” in the route map drawing area 204, the drawing route table 90
The coordinates of the drawing station table 902 are sequentially read based on the station index of 1 (FIG. 9), and when the coordinates corresponding to the coordinates of the selected area are found, the record of the table 901 or the record of the table 902 corresponding to the index. The route name 904 and the route display level 905 recorded in
Route name 915 and route display level 9 in the confirmed route table
Substituting 16 for each, station name 908, station display level 9
09 and coordinates 910 are respectively substituted into the station name 917, station coordinates 918, and station display level 919 in the route table.

When the selected area is "route", similarly to the above, the station drawing table 902 is sequentially searched to find a station close to the selected area, and the route name 9 of the route corresponding to this is found.
04 and the route display level 905 are respectively substituted into the route name 915 and the route display level 916 in the fixed route table.

13 and 14, 1301 and 13
02, 1401, and 1402 indicate screen transitions (scene 1 to scene 4) accompanying the operation. Also, 1303, 1304,
Reference numerals 1403 and 1404 represent the contents of the route table 914 corresponding to the scenes 1 to 4, respectively. In addition,
In the route table, the station of the first entry is "boarding station"
The line indicates the line on which the passenger boarded the train. The station of the second entry indicates "the station that got off the line of the first entry". Then, the route for the second entry is the second
Shows the route from the entry station. In this way, the route is stored in a form in which the stations and lines of the entry are sequentially connected alternately. Hereinafter, each scene of FIGS. 13 and 14 will be described. In this example, the operator is
Enter the route to reach station P10 via route c and route a.

Scene 1: Shows a state in which the operator designates the station P3, which is a boarding station, with the input device 5. Definite route table 1
Information about the station P3 (name, station display level, station coordinates) is stored in the station of the first entry 303, and the display of the station P3 is changed to the mark (triangle mark) of the boarding station on the screen. Since the route from the station P3 that can be boarded is only route A, the information of the route A (name, route display level) is stored in the route of the first entry. At this time, the route A is defined as the "attention line", and the route A on the screen is changed to a display format showing the "attention line" different from other normal routes. Further, the route (route c in this example) connected to the noted route A is defined as a “branch route”, and the display on the screen is changed to a display form indicating it.

Scene 2: Shows a state in which the operator selects the route c. Station P4, which is a transfer station for route A and route C, is set as the station of the second entry in the confirmed route table 1304. At the same time, the route c is set for the route of the second entry. Here, the route c becomes a new target route, and the display of the route c on the screen becomes the display form of the target route. Further, the display from the first entry to the station of the second entry in the fixed route table is changed to the display form of “fixed route”. The display of the final station P4 on the confirmed route changes to a mark (square mark) indicating "getting off station". In addition, the branch line will also be updated to Route A, which is a connecting route of Route C, which is a new hot line. When the operator selects the confirm button 206 in this state, the information of the confirmed route is set as the confirmed route information, and the route input program 14 is terminated.

Scene 3: Shows a state in which the operator has selected station P7. Station P7 is set as the station of the third entry in the confirmed route table 1403. As a result, the confirmed route on the display screen is extended from the state of scene 2 by the section corresponding to the station P4 to the station P7. At the same time, the disembarking station mark moves from station P4 to station P7. Since the designated station in this example is the station on the target route, the target route remains the same as the route c, and the target route on the display screen is the same as in scene 2.

Scene 4: Shows a state where the operator selects the station P10. Even if this operation is performed immediately after the scene 2, exactly the same result is obtained. Definite route table 1
The station of the third entry 404 is the station P8 which is a transfer station from the route C to the route A, and the route of the third entry is the route B. Further, the station P10 is set as the station of the fourth entry.

The above-mentioned routing is realized by the above operation and control. As the states of the fixed route table, there are two types of states, such as a state in which a route is set and a state in which a station is set, as in scenes 2 and 3. In the state where the route is set, the route of the last entry becomes the target station, and the station to the last entry becomes the confirmed route. In addition, the station of the last entry is considered as the disembarking station. On the other hand, in the state where the station is installed, the set station is set as the disembarkation station and the previous entry is set as the confirmed route. In addition, the route of the entry immediately before the final entry becomes the attention route.

FIG. 15 is a flow chart showing details of the individual area processing 806 of FIG. This routine consists of the following processing steps.

Process 1501: It is determined whether or not the designated region is the scroll button region, and if they match, then process 1502

The screen shifts to the boarding station P3.

Process 1507: It is judged whether or not it is in the disembarkation station movement button area. If they match, the process proceeds to process 1508, and if they do not match, the process proceeds to process 1509.

Process 1508: The process of moving to the disembarking station is performed.
By substituting the station coordinates in the last entry of the route table 914 into SRx and SRy of the equation 4, the disembarking station is changed to a display state in which it is located in the center of the route map area.

Process 1509: It is judged whether or not it is the station move button area. If they match, the process proceeds to process 1510, and if they do not match, the process proceeds to process 1511.

Process 1510: This station move process is performed. By using the terminal information table shown in FIG. 21,
The station where the ticket issuing terminal is installed is changed to a display state in which it is located in the center of the route map area.

The terminal information table 2100 has a process name 2101, a station name 2102, and a station display level attribute 210.
3 and station coordinates 2104. In the present embodiment, the number of entries in the table is 3, and it is composed of a record for this station movement processing, a standard 1 movement processing record, and a standard 2 movement record. The order of arranging these records is arbitrary, and by increasing the number of table entries, it is possible to meet the increase request of the movement processing type. In addition, the terminal information table 2100 is the station movement processing 1
In addition to 510, it is used in standard 1 movement processing 1512 and standard 2 movement processing 1514.

Process 1511: It is determined whether or not it is the forward tracking button region, and if they match, the process proceeds to process 1512, and if they do not match, the process proceeds to process 1513.

Process 1512: A forward movement process is performed.
In the forward movement processing, there are the following cases as the first station displayed at the center position after updating the route table or the condition. Display the boarding station. Only execute after the boarding station movement process is executed. Display the nearest transit station displayed in the current route map area.

When this area is selected for the first time after the route is specified, the boarding station is displayed at the center of the route map area by referring to the first entry in the route table 914.
After that, unless a new route is determined, each time this area is selected, the transit station of the second entry and the third entry is sequentially selected while referring to the route table until the arrival station is reached. , Display contents are changed in such a manner that a new transit station is sequentially located at the center of the route map area. By repeating this processing, when the alighting station is located at the center of the route diagram area 204, no further change in the screen display position occurs.

Process 1513: It is determined whether or not it is the backward tracking button area, and if it is one tracking button area, processing 1514 is performed.
Otherwise, to step 1515.

Process 1514: A backward moving process is performed.
In the backward movement processing, after updating the route table, there is a station that first moves to the central position, or there is the following hair ground as a condition. Disembarkation station Not executed unless the disembarkation station move processing is executed. The nearest transit station currently displayed on the route map area will be described here. When this area is selected for the first time after the route is designated, the last entry of the route table 914 is referred to and the alighting station is displayed at the center of the route map area. After that, unless a new route is determined, each time this area is selected, the transit station is selected sequentially while referring to the route table, and the display content is displayed so that it is located in the center of the route map area. Change. By repeating this processing, when the boarding station is located at the center of the route diagram area 204, no further change in screen display position occurs.

Process 1515: It is determined whether or not it is the standard 1 button region. If it is the standard 1 button region, the process proceeds to process 1516, and if not, the process proceeds to process 1517.

Process 1516: The standard 1 move process is performed.
Using the record information whose process name 2101 in the terminal information table 2100 is “standard 1”, the preset station is displayed according to the equation 4 so as to be the center of the route map area.

Process 1517: It is determined whether or not it is the standard 2 button region, and if it is the standard 2 button region, the process proceeds to process 1517.

Process 1518: Standard 2 move process is performed.
Using the record information with the process name 2101 “standard 2” in the terminal information table 2100, the display is changed according to the equation 4 so that the preset station is the center of the route map area.

In the station moving process, the standard 1 moving process, the standard 2 moving process, the forward tracking process, and the backward moving process described above, the operator explicitly specifies the display position. Some move processes are not explicitly performed. For example, when the route input program 14 is started, a desired display level and station can be displayed on the route map area. Such processing will be referred to as "initial movement processing" in this specification.

In the initial movement process, first, the station name 2102, the station display level 2103, and the station coordinates 2104 are read from the record having the process name 2101 “initial movement” in the terminal information table 2100, and the preset station is The display is changed using Equation 4 so that it is located at the center of the route diagram area.

FIG. 22 shows an example of a screen when the initial moving process is performed. In this example, the station P3 on the route A is the initial moving station and the initial zoom level is "region". This screen 2200 is a screen immediately after starting the route input program.

Next, the terminal information (terminal information table 2101) update screen displayed when the terminal information update starting means 17 is selected will be described with reference to FIG.

Area 2305: a scroll button,
The mouse is clicked when moving the area displayed in the route map display area. In this example, the display position can be fixedly moved in four directions, but the type / number of directions can be arbitrarily set according to the application.

Area 2306: a zoom level control area, which is used for controlling the resolution of the area displayed on the route map or the switching of the display area. By controlling this area, the operator can refer to the narrower range in detail and the wider range in general. The number of switching steps can be designed arbitrarily.

Area 2307: This is an initial movement button, and after clicking this area, selecting a station in the route chart time area 2301 updates the record relating to the initial movement in the terminal information table.

Area 2308: This station button, and by clicking this area, selecting a station in the route chart time area 2301 updates the record relating to the movement of this station in the terminal information table.

Area 2309: Standard 1 button. By clicking this area and selecting a station in the route chart time area 2301, the standard 1 in the terminal information table is selected.
The move record is updated.

Area 2310: Standard 2 button. By clicking this area and selecting a station in the route chart time area 2301, standard 2 in the terminal information table is selected.
The move record is updated.

Next, the terminal information updating process will be described. The operator firstly updates the items, that is, the initial move button 2306, the station button 2307, and the standard 1 button 230.
8 or standard 2 button 2309 is selected. This area determination is performed by the same process as the route input program 14. Next, a scroll button, a zoom level, etc. are operated and a desired station is displayed and selected. The information about the selected station, for example, the station name and the station coordinates are substituted into the record of the corresponding terminal information table 2100. At this time, as the station display level, the station display level 909 which is information on the station may be used, or the current display level may be used. The operator ends the terminal information update program by selecting the confirmation area 2303 after inputting the terminal information to be updated. Cancel end button 2
When 304 is selected, the terminal information table 2100
The terminal information update program is terminated without updating.

In this example, the realization method of displaying the designated station on the screen is shown. However, the display position of the desired station selected in the terminal information updating process is used as the display position in the moving process or in the upper left of the screen. Modifications such as displaying at a specific position such as an edge are possible.
