Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a route change technique, and more particularly to a data editing and data management technique when changing a cable route of a communication network or the like.
[0002]
[Prior art]
In a standard facility management system, graphic data of a facility on a map and the like and data accompanying the graphic data (generally called "attribute data") are linked and managed, and a data input function and a data editing function are used. It has a function, a search function, a drawing printing function, and the like. As for the data editing function of the facility management system, as described in Japanese Patent Application Laid-Open No. 7-244995, a technology for realizing an easy-to-understand GUI has been studied. One of the standard functions of the data editing function of the equipment management system is, for example, a cable route changing function. Changing the route of a cable means arbitrarily changing the route of a section from a given utility pole to a utility pole for a registered cable.
[0003]
With reference to FIG. 19, a general operation method of the route change function will be described. First, a cable whose route is to be changed is specified on the drawing (screen). In the example shown in FIG. 19A, a power pole B, a power pole C, and a power pole D are present on the way from the power pole A to the power pole E, and cables are stretched in that order. Next, when the utility pole (the utility pole B) for starting the route change of the cable is designated (FIG. 19 (2)), and the adjacent utility pole (the utility pole C) is designated, the cable figure between the designated utility poles B to C is displayed, for example. It is selectively displayed with a bold line (FIG. 19 (3)). In this manner, the adjacent utility pole is designated until all the cable figures of the section to be changed are selected (in this case, up to utility pole D), and the change section designation is completed by pressing, for example, the Enter key for confirmation. Then, the system enters the post-change route designation waiting state (FIG. 19D).
[0004]
Next, the route change destination is designated by sequentially selecting telephone poles from the drawing (in this example, the telephone pole F, the telephone pole G, and the telephone pole H are sequentially specified) (FIGS. 19 (5) and (6)). Finally, when the last electric pole (the electric pole D in this example) of the route change section is designated and the Enter key is pressed, the change section is redrawn and the new route (the electric pole A to the electric pole B to the electric pole F to the electric pole G to the electric pole G) is drawn. Cables of utility pole H to utility pole D to utility pole E) are drawn (FIG. 19 (7)). By the above procedure, the cable route can be changed.
[0005]
[Problems to be solved by the invention]
However, when the above-described route change function is used, the operation is complicated because it is necessary to specify each utility pole of the section to be changed. In particular, when the section to be changed is long and a large number of utility poles are provided therebetween, a large number of utility poles must be designated in the drawing. Further, when there is a place where the cable is looped (it passes between two telephone poles a plurality of times), it is not possible to judge how many times the cable is looped in the loop section. There is also a problem that the processing becomes complicated.
An object of the present invention is to improve the operability of a function of changing a cable route.
[0006]
[Means for Solving the Problems]
According to one aspect of the present invention, there is provided a route change system for changing a route having points at both ends and a middle of the route, wherein the point management unit manages the route for each point-to-point information divided by the adjacent points. By specifying a database having an information table, a route change section start point for starting a route change, and a route change section end point for ending a route change, the route change section start point and the route change section end point A route change system is provided which has a route extracting means for extracting a route connecting between the two, and a route selecting means for selecting a route to be changed from the extracted routes.
[0007]
According to the route change system, since the route change system has the point-to-point information table that manages the route for each point-to-point information divided by the adjacent points, the route change section start point for starting the route change and the route By designating the route change section end point at which the change of the route is completed, it is possible to extract all routes between the points without selecting a midway point.
Further, it is preferable to have a point-to-point information updating means for updating the contents of the database based on the contents of the change processing of the selected route. The point-to-point information after the change can be newly made into a database.
[0008]
The point-to-point information table stores the point-to-point information and the order of the point-to-point information counted from one end of the both ends in association with each other. When a route connecting a point and the route change section end point has a loop that passes through the same section a plurality of times, the route is distinguished for each connection form of the plurality of point information and the order of the point information is determined. It is preferable to extract as the change target route a combination of the order sequences related to each other, the combination having the same order as the order of following the route.
[0009]
By using the above system, a change target route in a change target section can be extracted without duplication.
According to another aspect of the present invention, there is provided a route change system for changing a route having a plurality of points, comprising a point-to-point information table that manages the route for each point-to-point information sectioned by adjacent points. By specifying a database and a route change section start point for starting a route change and a route change section end point for ending a route change, the route change section start point and the route change section end point can be specified. A route change system is provided that has a display unit that extracts a connecting route and prompts the user to select a route to be changed from the extracted routes.
[0010]
Since the route change system has a point-to-point information table that is managed for each point-to-point information, the route change section start point and the route change section end point are designated to prompt selection of the route to be changed. A route selection table can be displayed, and the route can be changed by a simple operation. For example, it is also possible to automatically analyze a route pattern connecting two facilities passing through a designated route from a map screen, display the pattern on a list screen, and display a route selected in the list on the map screen. It is possible.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
The inventor has conceived of managing a cable for each cable figure (point-to-point information) divided by an adjacent point when changing the route of a cable or the like having points at both ends and the middle of the route. When actually changing the route, the route configuration in the route change target section is managed for each cable figure, so if you specify the start and end points of the route change target section, all routes will be extracted can do.
[0012]
Hereinafter, based on the above consideration, a cable route changing technique according to an embodiment of the present invention will be described with reference to the drawings, taking a communication network equipment management system as an example.

The table has a cable graphic ID and management items as management items.
[0023]
Next, a description will be given of a cable route change operation procedure by the cable route change function according to the embodiment of the present invention with reference to FIGS. Hereinafter, an example will be described in which the route changing function is used to change the cable passing through the utility poles A to B to C to D to the route of the utility poles A to B to F to G to D to E. FIG. 3A shows a state before the route change. Between the closure α and the closure β, between the pole A and the pole E, there are the pole B, the pole C, and the pole D, and between these poles between the pole A and the pole E. Cables are provided. FIG. 3B shows a state in which a cable whose route is to be changed is specified. When the route change target cable displayed on the display is designated by, for example, a mouse, the designated cable is selectively displayed.
[0024]
FIG. 3C shows a state in which the starting equipment of the route change section is designated. When the electric pole B serving as the start end of the section for which the route is changed is designated using, for example, a mouse or the like, the designated electric pole is selectively displayed. FIG. 3D shows a state in which the terminal equipment of the route change section is specified. When the electric pole D which is the end of the section for which the route is to be changed is designated by a mouse, the designated electric pole is selected and displayed, and the cable figure between the electric poles B to C to D, which is the section defined by the starting equipment and the end equipment, is routed. Designated as a change section. At this time, a rubber band (lead line) is displayed from the start equipment of the changed section.
[0025]
FIG. 4 (5) shows a state in which the change destination route is being specified, and FIG. 4 (6) shows a state in which the change destination route has been specified. The route to be changed is specified by sequentially specifying telephone poles on the map. When the process up to the terminal equipment of the route change section is specified and the process is confirmed by, for example, pressing the Enter key, the change destination route specification process is completed. FIG. 4 (7) shows a state in which the route change processing has been completed. The cable figure of the section before the change is deleted, and the cable is changed to a cable passing through the utility poles AB, BF, GH, and DH.
[0026]
FIGS. 5 to 7 illustrate the operation procedure of the route change function according to the present invention when the cable is looped and there are a plurality of routes connecting the start and end equipment of the change section. In such a case, it is necessary to analyze the loop structure of the cable. FIG. 5A is a diagram illustrating an example of a route change process for a looped cable. The cable before the route change actually takes the route of telephone poles A to B to C to E to B to C to D, and passes twice between the pole B and the pole C respectively. In this manner, a cable that has passed through the same facility (electric pole) twice or more is referred to as a looped cable. An example in which the “B-C-E-B-C” section (before the change) of the cable is changed to the cable route “B-FC” (after the change) will be described.
[0027]
FIG. 5 (2) shows a state in which a route change target cable is designated, FIG. 5 (3) shows a state in which a utility pole B which is a route change section starting end equipment is designated, and FIG. 6 (4) shows a route change. It is a figure which shows the state which specified the electric pole C which is a section terminal equipment. When there are a plurality of patterns as sections connecting the start end and the end of the route change section, when a change section end equipment is designated, a change section selection screen is displayed. The change section selection screen displays a list of all the patterns of the section connecting the start equipment and the end equipment of the route change section. A method for creating this pattern will be described later.
[0028]
In the example of (4) in FIG. 6, there are four routes connecting the utility pole B to the utility pole C, and these are displayed as a list. Note that there are two patterns “B to C”. These are a pattern in which the cable figure of order 2 shown in FIG. 5A is a change section and a pattern in which the cable figure of order 5 is a change section, and indicate different sections. FIG. 6 (5) shows the map screen when each of the four patterns is selected in the list. When any of the patterns in the list of the change section selection screen displayed in FIG. 6 (4) is clicked with the mouse, the cable figure of the selected section is highlighted on the display 1 as shown in FIG. 6 (5). Is displayed. When the section to be changed is “B-C-E-B-C”, when the pattern 2 is clicked on the list, as shown in the pattern 2 in FIG. All the cable figures between the power poles EB and between the power poles BC are highlighted.
[0029]
When the "OK" button is pressed in this state, the selected pattern is designated as the route change section, the change section selection screen disappears, and a rubber band is displayed from the route change section start end equipment as shown in (6) of FIG. Then, the route designation processing after the change can be performed. FIG. 7 (7) shows a state in which a route change destination is being specified, and FIG. 7 (8) shows a state after execution of the route change. The operation is the same as when the cable is not looped, and the route change is completed by the above processing.
[0030]
FIGS. 8 and 9 are diagrams for explaining the function of the “display” button (hereinafter referred to as “pattern display function”) in the change section selection screen of FIG. 6D. The pattern display function is used to distinguish patterns having the same display on the list, such as “pattern 1 (paths B to C)” and “pattern 4 (paths B to C)” in FIG. This is the function used. When a pattern is selected from the list and the "display" button is pressed, a symbol indicating the position is displayed on the cable, and the cable moves from the beginning to the end of the cable. The first symbol, for example, is displayed in black while the symbol is passing through the route change target section, and the second symbol, for example, is displayed in white while passing through the other sections. It is easy to identify the currently selected section by checking at which point (in the section moving) the symbol changes to black.
[0031]
FIG. 8 shows an example in which “pattern 1 (routes B to C)” is selected on the change section selection screen in FIG. 6D and the “display” button is pressed. First, a rhombus symbol moves in the direction of the arrow on the cable from the telephone pole A, which is the starting end of the cable, to the telephone pole B, which is the next transit facility. Since this section (AB) is not included in the “B to C” section selected in the list, the symbols are displayed in white. Next, as shown in FIG. 8B, the symbol moves from the utility pole B to the utility pole C. Since this section is a section currently selected in the list, the symbols are displayed in black, which is different from white. Next, as shown in FIGS. 8 (3) and (4), the symbol moves from the utility pole C to the utility pole E and from the utility pole E to the utility pole B. Since these are outside the section selected in the list, the symbols are displayed in white. Next, as shown in FIG. 9 (5), the symbol moves from the utility pole B to the utility pole C. The pattern selected in the list is "B to C", but indicates the cable figure of order 2, and the currently passed cable pattern of order 5 is selected in the list. It is out of the section and the symbol is displayed in white. When the symbol moves to the end D of the cable as shown in FIG. 9 (6), the symbol disappears, the display returns to a state waiting for an instruction from the operator on the change section designation screen, and the processing by the pattern display function is completed.
[0032]
FIG. 10 is a flowchart illustrating the flow of the cable route change process. The route change process will be described with reference to FIG.
(1) A cable designation process is performed (step S1001). Accepts the operator's specification and selects and displays the route change target cable. (2) Perform route change section start end equipment designation processing (step S1002). Accepts the operator's designation and selects and displays the start equipment of the route change section. (3) Route change section terminal equipment designation processing is performed (step S1003). Accepts the operator's designation and selects and displays the route change section terminal equipment. In the cable route change technology according to the present embodiment, the utility pole is designated as the start and end equipment of the change section. However, other equipment, such as a closure or a cable figure, is designated, and the start section of the change section is determined from those utility pole IDs. A method of performing the following processing after obtaining the power pole and the terminal power pole may be adopted. (4) Automatically analyze the pattern of the section connecting the start and end facilities of the route change section (step S1004). Details of the pattern analysis processing will be described later with reference to FIGS. 11, 12, and 13. If the number of patterns is two or more, a change section selection screen is displayed (step S1006). When "OK" is pressed on the change section selection screen, the pattern selected in the list is set as a route change target section, and when "Cancel" is pressed, the command is terminated (step S1007). (5) Route change destination designation processing is performed (step S1009). From the start equipment of the route change section, a rubber band connecting the designated telephone poles is displayed, and the information on the designated telephone poles is stored. (6) Execute a route change process (step S1010). Update figures and databases. This processing will be described later with reference to FIG.
[0033]
FIG. 11 is a flowchart of the pattern automatic analysis, FIG. 12 is a flowchart of the subroutine of FIG. 11, and FIG. 13 is a data example of the pattern automatic analysis based on the same data as FIG. With reference to these figures, the automatic analysis processing of the section connecting the route change section start and end facilities will be described. As shown in FIG. 11, in the pattern automatic analysis processing, first, a pattern in the forward direction of the cable is searched (step S1101), and then a pattern in the reverse direction of the cable is searched (step S1102). These processes will be described with reference to FIGS.
[0034]
In FIG. 13A, there is a cable of a route called "electric pole ABCBECD", and a route from the electric pole B (change section start end) to the electric pole C (change section end) is routed. It indicates that it has been specified as a change target. As the cable graphic, a cable graphic ID, a cable ID, a terminal 1 power pole ID, a terminal 2 power pole ID, and an order in a route of “power pole ABCCBCD” are shown. I have. The cable graphic ID is designated from α to ξ, and the cable ID is one cable and is set to 1. Orders 1 to 6 are assigned to respective route sections between the terminal 1 pole and the terminal 2 pole.
[0035]
FIG. 13B shows a pattern of a route connecting the electric pole B and the electric pole C in the above data example. When the cable is traced from the beginning, the section that becomes the utility poles B to C is "A- BC -E-B-C-D "and" A- BCEBC -D "" A-B-C-E- BC -D ". It is not necessary that the direction of the cable coincides with the direction of specifying the change section when selecting the cable route change target section. Next, when the section that follows the cable from the reverse direction and becomes the utility poles B to C is searched, "AB- CEB -CD ". In the pattern automatic analysis processing, a pattern in the forward direction is searched first, and then a pattern in the reverse direction is searched. FIG. 12 shows a flowchart of the process (steps S1101 and S1102 in FIG. 11) of searching for the respective patterns in the forward direction and the reverse direction. The pattern search process will be described with reference to the data examples of FIGS.
[0036]
(1) First, a pattern in the forward direction is searched. The utility pole ID of the utility pole (the utility pole B) designated as the start utility pole of the route change section is stored in the variable s, and the utility pole ID of the utility pole (the utility pole C) designated as the terminal equipment is stored in the variable e (step S1201, step S1202). ).
[0037]
(2) As search A, a cable graphic record having a terminal ID of the first pole of the variable s is acquired from the cable graphic table (step S1204). In the example of FIG. 13, when a cable figure record having the utility pole ID of the utility pole B as the terminal 1 utility pole ID is searched, the cable figures β and ε are acquired as shown in FIG.
[0038]
(3) As the search B, a cable graphic record having the value of the variable e in the terminal pole ID is acquired from the cable graphic table (step S1205). In the example of FIG. 13, when a cable figure record having the utility pole ID of the utility pole C in the end two utility pole IDs is searched, the cable figures β and ε are searched as shown in FIG.
[0039]
(4) The cable figures obtained in the search A and the search B are combined two by two in a round robin manner (from step S1206 to step S1210, the patterns in FIGS. 13 (3) and 13 (4)), and the “order” of the cable figures Compare. Assuming that the two cable figures to be compared in order are m and n, respectively, if the order satisfies m ≦ n, it can be determined that the combination is one of the route change section patterns (step S1210). In the example of FIG. 13, as shown in FIG. 13 (5), there are four combinations, and when judging from the value of “order”, the three types indicated by ○ in the table are route change section patterns.
[0040]
(5) For the combination that has become the route change section pattern in the above (4), a cable figure of the route to be routed is searched, and a character string indicating the route such as “Route B to C” is created (step S1211). This pattern character string is used to display the route that has become the route change pattern on the change section selection dialog of FIG. 6D. FIG. 14 shows an example of pattern character string generation. FIG. 14 illustrates the pattern character string generation processing by taking the combination of the order 2 and the order 5 indicated by * in FIG. 13 (5) as an example. When the records having the order of 2 or more and 5 or less are searched from the cable graphic table in the ascending order of the order, the cable figures β, γ, δ, and ε are obtained. By arranging the utility poles of these cable figures in order, a character string “Route B to C to E to B to C” is generated. The other patterns (orders 2 and 2 and orders 5 and 5) selected as the route change patterns in FIG. 13 (5) are also the same as the pattern character strings (“paths B to C” and “paths B to C”). )). Thus, the pattern analysis in the forward direction is completed.
[0041]
(6) Next, a pattern in the reverse direction is searched. The utility pole (the utility pole C) designated as the route change section terminal equipment is stored in the variable s, and the utility pole (the utility pole B) designated as the starting equipment is stored in the variable s (steps S1201, S1203).
[0042]
(7) As search A, a cable figure having the utility pole of the variable s as the terminal 1 equipment ID is acquired (step S1204). In the example of FIG. 13, a cable figure having the utility pole C as the end one utility pole ID is searched, and the cable figures γ and ζ are acquired as shown in FIG.
[0043]
(8) As the search B, a cable figure having the utility pole of the variable e in the end two utility pole ID is acquired (S1205). In the example of FIG. 9, a cable figure having the utility pole B as the end two utility pole ID is searched, and the cable figures α and δ are acquired as shown in FIG.
[0044]
(9) The cable figures obtained by the search A and the search B are combined in a round robin manner (step S1206 to step S1210). When the “order” of the two records is compared (step S1210), two cable figures for comparing the order are obtained. Are m and n, respectively, as shown in FIG. 13 (8), there are four combinations in all rounds, and if determined by the value of “order”, one pattern indicated by a circle in the table becomes a route change section pattern. .
[0045]
(10) With respect to the combination that has become the route change section pattern in (9), a route to be passed is searched for and a pattern character string is generated. When the records in the order of 3 or more and 4 or less are searched from the cable figure table in descending order of the order, the cable figures γ and δ are obtained. By arranging the electric poles in these cable figures in the order of the end 2 electric pole ID and the end 1 electric pole ID, a character string “Route B to E to C” is generated. Thus, the pattern analysis in the reverse direction is completed, and a total of four patterns are searched for in the forward direction and the reverse direction.
[0046]
The above analysis processing can be briefly summarized as follows. In the extraction of the selected section, a combination of the order of the cable figure is first extracted by considering it as a section of the cable figure. That is, a correct combination is a combination from small to large when viewed in ascending order, or a combination of completely equal (single) sections. When viewed in descending order, the combination is large to small. Other combinations are out of scope.
[0047]
FIG. 15 is a flowchart illustrating the flow of the route change execution process. The route change execution process will be described with reference to FIG.
(1) A cable figure table record, a cable figure management table record, a cable figure management table record, and a cable figure figure element corresponding to a cable figure of a route change section are respectively represented by a cable figure table, a cable figure management table, and a cable figure layer. , (Step S1501).
(2) It is checked whether the designated direction of the route change section matches the direction of the cable (step S1502). If the direction is the reverse direction, the route change section is reversed and the route change section is reversed, and the change section start end equipment and end equipment Are exchanged (Step S1503, Step S1504). For example, in the case of FIG. 13 (2), when “routes B to E” are selected, the telephone pole C is internally designated as the start end of the route change section, and the telephone pole B is specified as the end of the route change section. Shall be.
(3) Draw a cable graphic symbol between the utility poles from the pole at the beginning of the route change section to the pole at the end of the route change section via the pole designated as the route change destination (step S1506) and newly register it. The “order” of the cable graphic records is acquired (step S1507), the cable graphic records are registered in the cable graphic table (step S1508), and the cable graphic management records linking the graphic and the cable graphic records are registered in the cable graphic management table.

FIG. 16 is a diagram illustrating values of the cable connection table and the cable graphic table before and after executing the route change function of FIGS. 5 to 7. The attribute database whose data is updated by the route change function is only the cable graphic table, and the value of the cable connection table is not updated. FIG. 16A shows the values of the database before the route change, and FIG. 16B shows the values of the database after the route change. The record of the cable figures β, γ, δ, and ε between the power poles B to C to E to B-C, which is the route change section, is deleted, and connects the power poles B to F to C as the post-change route cable figure. Cable figures η and θ are registered.
[0049]
The “order” value of the newly registered cable figure is given so that the intervals between the records before and after the route change section, that is, the “order” values of the cable figures α and に な る become equal. In this example, since the order of the cable figure α is 1 and the order of the cable figure ζ is 6, the values between them are evenly divided, and from the front, 1, 2.667, 4.333, 6 (interval is 1. 666 to 1.667).
[0050]
FIG. 17 is a flowchart illustrating a flow of a process for acquiring the “order” value of the new cable graphic. The “order” value acquisition processing will be described with reference to FIGS. 16 and 17.
(1) The number of new route cable figures after the change is counted and stored in a variable n (step S1701). In the example of FIG. 16, there are two cable figures at the route change destination between the telephone poles BF and between the telephone poles FC.
[0051]
(2) A record immediately before the change section is searched from the cable figure table (step S1702). If there is no data (the cable figure at the beginning of the cable is included in the route change target section), 0 is set to the variable s. Is stored (step S1704), and if there is data, the order value of the record is stored in the variable s (step S1705). In the example shown in FIG. 16, the cable figure α is retrieved, and 1 is stored in s.
[0052]
(3) The record after the change section is searched from the cable figure table (step S1706). If there is no data (the cable end cable figure is included in the route change target section), “1” is set to the variable “inc”. Is stored (step S1708). If there is data, the order value of the record is stored in the variable next, and (next-s) / (the number of cable figures + 1) is stored in inc (steps S1709 and S1710). In the example shown in FIG. 16, the cable figure 検 索 is searched and next is 6, so (6-1) /3=1.66666... Is the value of inc.
[0053]
(4) The order of each cable figure is obtained by s + (inc * i) (step S1711). i is an index when the cable figure to be newly registered is 1, 2,. In the example of FIG. 16, the cable figure order between the utility poles BF is 1+ (1.6666... * 1) = 2.6666..., And the cable figure order between the utility poles FC is 1+ (1.6666... * 2). = 4.3333. Through the above processing, the “order” of the new cable graphic is obtained.
[0054]
FIG. 18 is a flowchart of the pattern display function. The pattern display processing will be described with reference to FIG. (1) The display interval of the symbol corresponding to the current map display scale is acquired (step S1801). (2) Retrieve all cable figures of the route change target cable in ascending order of “order” (in descending order when the designated direction of the change section is the reverse direction to the cable) (step S1802). (3) A loop is performed for the number of searched cable figures, and display is performed for each figure (step S1803). First, it is determined whether the cable figure is included in the section of the currently selected pattern (step S1804). If it is included, the symbol display color is set to black, and if not, the symbol display color is set to white (step S1804). S1805, step S1806).
[0055]
(4) The coordinate data of the cable graphic is obtained (step S1807), and the symbol is displayed at a position advanced by w meters from the start coordinate of the cable graphic to the coordinate of the end point for a predetermined time (step S1808). When the designated direction of the change section is the opposite direction to the cable, the display is performed from the end point coordinates to the start point coordinates. (5) After displaying for a fixed time, the symbol is deleted (step S1809). (6) Repeat until the end of the cable is repeated by the number of cable figures (step S1810, step S1811). Thus, the pattern display processing is completed.
