Description

TECHNICAL FIELD [0001] The present invention relates to a method for correcting information in a linear infrastructure management system,

The present invention relates to GIS-based facilities management, and more particularly to linear network data and facility management systems attached thereto.

Geographic Information System (GIS) is a computer system that can visualize the spatial location and property information of natural objects and artifacts, input, edit and analyze these data. Geographic Information Systems (GIS) can gather and use computer hardware, software, and geographic data that are designed to collect, store, update, coordinate, analyze, and represent all types of geographically referential information effectively.

GIS is a system for storing, extracting, managing, and managing information by linking geographical information that represents a spatial location for various earth surface information references and non-graphic attribute information that explains and complements its form and function with graphical and database management functions. It is an information system related technology to analyze, and it is a comprehensive analysis means that expresses the spatial relation of map by adding characteristic (attribute) information of the geographical information. Geographic data occupying spatial position and related attribute data are integrated and processed. GIS can be widely used in land information management, facility management, transportation, urban planning and management, environment, weather forecasting, agriculture, disaster and disaster, education and population prediction.

From the point of view of the purpose of use, GIS can be divided into Facility Management (FM) system and decision support system for planning support, Land Information System (LIS) (UIS: urban information system).

Conventionally, the city information system of GIS manages only the location (space) information of the facilities, and the linear information correlated with the facilities is provided in the form of a background map. In addition to the linear spatial information, which is the matrix of the facility, the system manages only the information of the simple facilities and focuses on the management of individual facilities.

In the case of such a conventional system, there is no shortage in the management of individual facilities, but there is no relation with the linear form of parent spatial information (for example, roads, railways, etc.) It is difficult to support. Also, there have been pointed out problems such as limitation of usability due to simple location identification method, analysis of facilities and inaccuracy of statistics.

From the 1970s to the present, if the construction of the road sector tended to focus mainly on new roads, it is now necessary to have huge funds to maintain and repair the existing roads. It is a situation.

The conventional GIS system for facility management manages only the location (space) information of the facility, and the linear information correlated with the facility is served in the form of a background map. In addition to the linear spatial information, which is the matrix of the facility, the system manages only the information of the simple facilities and focuses on the management of individual facilities.

In the case of such a conventional system, there is no shortage in the management of individual facilities, but there is no relation with the linear form of parent spatial information (for example, roads, railways, etc.) It is difficult to support. Also, there have been pointed out problems such as limitation of usability due to simple location identification method, analysis of facilities and inaccuracy of statistics.

In addition, there is a problem of management inefficiency that the location information of the facility to be managed must be manually modified when the linear object is updated, and it is difficult to correct the facility location information to reflect the change in the information or spatial shape of the linear object .

It is an object of the present invention to provide a linear infrastructure management system that interoperates with a GIS base and stores and manages information related to a linear object such as a road in correlation with a property of a linear object.

It is another object of the present invention to provide a linear infrastructure management system that can automatically correct facility locations without manual operation when updating linear objects.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the present invention will be realized and attained by the structure particularly pointed out in the claims, as well as the following description and the annexed drawings.

The linear infrastructure management system according to the present invention is expected to provide a smart environment for facility management linked to a network in conjunction with various GIS spatial information based analysis functions other than linear object unit inquiry operations.

The present invention relates to a line segment object having a direction and an event (e.g., peripheral facilities, ancillary items, etc.) linked to the linear object and managing the linear object, (For example, surrounding facilities, accessories, etc.) can be easily corrected.

The linear infrastructure management system according to the present invention can represent and manage information of events (e.g., nearby facilities, appendages, etc.) more intuitively than the conventional management system.

In addition, when the linear object is updated, the function of automatically correcting the location of the facility is implemented without any manual work, and the relative position information of the facility and the ambiguity of the management information due to frequent updating of the map are removed.

Recently, government ministries and municipalities are planning to actively introduce the latest information technology (IT) for integrated management of road pavement, traffic, and facilities. In particular, the introduction of information technology (IT) is strongly recommended to the municipalities in order to improve the efficiency of the management of roads and auxiliary facilities. Although information technology (IT) has been used in some fields of road facility management in the past, the present invention aims to integrate the road management system into one and eliminate redundant and inefficient work such as reproduction of information, As a different approach from the existing method, we proposed a linear infrastructure management system.

The node table stores information expressing the correlation between the information about the linear point of the linear object and the linear objects.

The cross-reference information table stores connection information between the linear object and the facility.

The linear information table stores and manages additional information of the linear object.

The block diagram of FIG. 1 also shows the configuration of the control unit according to the present invention.

FIG. 2 is a diagram illustrating a linear infrastructure management model according to the present invention, and FIG. 6 is a flowchart illustrating a facility management method according to the present invention.

In the present invention, a linear object to be managed (for example, a linear object A and a linear object B) is referred to as a unit linear object, and a unit linear object is composed of a repetition of a straight line and a curve and has a direction from the viewpoint to the end point.

6, the management system 100 refers to the storage information of the facility management unit 200 and the linear object management unit 300 to register the facilities and the facilities Search for adjacent linear objects and find the normal and intersection points (Mp) between the detected linear objects and facilities. (S110)

The management system 100 obtains the distance M from the viewpoint of the linear object to the intersection Mp and obtains the straight line distance D to the intersection Mp and the facility. (S120 to S130) In addition, the direction information of the facilities on the linear object is calculated based on the clockwise direction in which the end point of the linear object is oriented. Then, a sequence number (SEQ) is allocated to each facility using the distance M. (S140 to S150)

Thereafter, when the new facility is added (registered), the management system 100 calculates the sequence number (SEQ) of the additional facility using the distance M and calculates the number of the additional facility based on the calculated sequence number SEQ Adjust the order of other connected facilities (s). (S160 to S170) The management system 100 arranges and manages the order of the facilities in the order of the closest distance M from the viewpoint of the linear object.

If the position or shape of the linear object or the facility is changed in the future, the management system 100 calculates the linear object-based facility correction position using the detected normal line and the intersection Mp. (S160 to S170)

The calculated information (e.g., linear object ID, distance between facilities M, SEQ information, correction position information, facility direction information, etc.) Lt; / RTI >

The management system 100 according to the present invention supports efficient facility management by allowing a plurality of linear objects (e.g., linear object A, linear object B) to form one line, as shown in FIG. In this case, each linear object forming one line is referred to as a unit linear object, and the unit linear object is composed of a repetition of a straight line and a curve, and has a start point and an end point.

The information of the route, which is a group of linear objects, is defined in the route management table as shown in Table 1 below.

[Table 1]

The management system 100 defines the connection type of the linear objects based on the TAG (field item) of the continuous point in the above [Table 1]. For example, if a linear object B is connected after the linear object A, the ORD (field item) of the linear object A is assigned 1 and the ORD (field item) of the linear object B is assigned 2. If the point of the linear object B is connected to the linear object A, the point TAG (field item) of the linear object B is set to the 'point of view'.

Figure 3 is an illustration of a facility management model for a linear object having no normals.

For facility registration, the management system 100 first searches for a linear object closest to the facility, and finds the normal and intersection Mp between the linear object and the facility searched.

In this example where there is no normal line between the searched linear object and the facility, the management system 100 designates the inflection point of the shortest distance point from the facility as an intersection Mp, Mp), and obtains the straight line distance (D) from the intersection (Mp) to the facility.

FIG. 4 is a diagram illustrating a procedure for assigning and managing a facility number in accordance with the present invention.

When the management system 100 obtains all kinds of information (e.g., normal line, intersection Mp, distance M, straight line distance D, direction information of facilities, etc.) defining the relationship between the linear object and the facility, (SEQ) to each facility (e.g., facility 1 and facility 2) as shown in FIG. 4A.

When a new facility (e.g., facility 3) is added, the sequence number (SEQ = 2) of the additional facility 3 is calculated using the distance M, and the calculated number And adjusts the order of the other facility (s) connected to the linear object based on the sequence number (SEQ = 2).

FIG. 5 is an exemplary diagram of a management model for a line composed of several unit linear objects according to the present invention.

As shown in FIG. 5, the unit linear object B is connected in the reverse direction to the neighboring linear objects (e.g., the unit linear object A and the unit linear object C). In the present invention, when some unit linear objects are connected in the reverse direction, the facilities can be sequentially inquired by searching the sequence in reverse order. This is possible because the present invention assigns and manages individual attributes to each unit linear object.

The present invention supports an efficient facility management service by comparatively analyzing or automatically assigning properties of facilities (events) connected with properties of a unit linear object.

FIG. 7 is an exemplary view of a facility management model when the shape of a linear object is changed. FIG.

7, when the shape of a linear object is changed (modified), the present invention moves the facilities on the existing linear object (e.g., linear object A) to the changed linear object (linear object A ') So that even if a change occurs in the linear object, the unique position of the facility at the time of occurrence is maintained as it is. When the individual unit linear object is changed, the position of the facility (event) is automatically adjusted through the distance (M) and the straight line distance (D) without user's input.

7, the management system 100 may calculate the location of the facility 1 (e.g., a milestone) based on the connection information stored in the storage unit 500. In this case,

8 is an operation algorithm of the facility management method when the shape of the linear object is changed.

The management system 100 first searches all the facilities connected to the linear object A on the basis of the sequence (SEQ), and creates a list (List L) about the detected facilities. (S210) Then, the system checks the distance M from the time point of the linear object A before updating to the facility (for example, N = 1) by sequentially inquiring from the first facility (for example, N = 1) do. (S220 to S240)

Then, a point (X, Y) separated by the distance M from the time point of the updated linear object (e.g., the preceding object A ') is calculated and the facilities (e.g., N = (X ', Y'). (S250 to S260)

Then, the connection location information of the facility is updated to (X, Y) and (X ', Y'). (S270)

The management system 100 repeats the above procedure for the remaining facilities on the list L (S280 to S290), and updates the connection location information of all the facilities on the list L (List L).

FIG. 9 is an exemplary view of a facility management model when the length of a linear object is changed. FIG.

As shown in Fig. 9, this example is a case where the length of the object is shortened (or longer), and the position information of the facility is corrected by adding the changed length alpha to the distance M of each facility.

10 is an operation algorithm of the facility management method when the length of the linear object is changed.

As shown in FIG. 10, the management system 100 searches all the facilities connected to the linear object A based on the sequence SEQ and creates a list (List L) about the detected facilities. (S310) Then, the system checks the distance M from the time point of the linear object A before updating to the facility (for example, N = 1) by sequentially inquiring from the first facility (for example, N = 1) do. (S320 to S340)

The new distance information M 'is calculated by adding the changed length M to the confirmed distance M in step S350 and the distance information M of the facility is updated with the new information M' . (S360)

The management system 100 repeats the above procedure for the rest of the facilities on the list L to update the distance information M of all the facilities on the list L through steps S370 to S380.

11 is an exemplary diagram of a facility management model for a case where linear objects are merged.

11, this example shows the distance from the new point of view (e.g., Node B) of the merged linear object (e.g., Linear Object A, Linear Object B) ) To reconnect the facilities based on the new time (eg, Node B).

In the case of a facility management model in which linear objects (e.g., linear object A and linear object B) are merged, the management system 100 calculates the distance (M ') between the point of the merged linear object and the point of the linear object before merging And calculates and manages the distance (M + M ') from the new viewpoint in addition to the existing distance (M).

12 is an operation algorithm of the facility management method when the linear objects are merged.

12, the algorithm of the present example adds the maximum sequence number (SEQ) among the sequence numbers (SEQ) of the facilities connected to the linear object A to the sequence number (SEQ) value of the facilities connected to the linear object B, (SEQ) of the facilities connected to the facility.

The management system 100 first searches all the facilities connected to the linear object B based on the sequence (SEQ), and creates a list (List L) about the detected facilities. (S410) Then, it inquires from the first facility (for example, N = 1) on the list (List L) sequentially and confirms the distance M from the viewpoint of the linear object A before the update to the facility do. (S420 to S440)

The new distance information M 'is calculated by adding the length of the preceding object A to the determined distance M. (S450)

The management system 100 then adds the largest sequence number (SEQ) of all facility sequences (SEQ) of the linear object A to the sequence (SEQ) of the facility (for example, N = 1) (SEQ) < / RTI > (S460)

The distance information M of the facility (for example, N = 1) is updated with the linear object A '(S470) by updating the connected linear object (e.g., linear object B) And the sequence number (SEQ) to the new value (M ', SEQ'). (S480)

The management system 100 repeats the above procedure for the rest of the facilities on the list L at steps S490 to S500 so that the distance information M and the SEQ of all the facilities on the list L Update.

13 is an exemplary diagram of a facility management model for a case where a linear object is divided.

13, this example shows a linear object (e.g., linear object A) when one linear object (e.g., linear object A) is divided into two (e.g., linear object A ', linear object B) To be connected to a separate linear object (e.g., linear object B).

14 is an operation algorithm of a facility management method when a linear object is divided.

As shown in FIG. 14, the management system 100 searches all the facilities connected to the linear object A based on the sequence (SEQ) and creates a list (List L) about the detected facilities. (S510) Then, the sequence (SEQ) of the facilities distant from the viewpoint of the linear object A to the facility is distant from the Node B point is derived, and the sequence (SEQ) is set to the value of PIVOT. (S520)

(N = PIVOT) from the derived sequence (SEQ) in the list (List L), and calculates the distance from the time point of the linear object A before the update (e.g., N = PIVOT) (M). (S530 to S550)

The new distance information M 'is calculated by subtracting the length of the segmented linear object (e.g., the preceding object A') from the identified distance M. (S560)

The management system 100 then subtracts the PIVOT value from the SEQ of the facility (e.g., N = PIVOT) and then adds 1 to the facility (e.g., N = PIVOT) (SEQ '). (S570)

[Equation]

Sequence (SEQ ') = Sequence of facility (SEQ) - PIVOT + 1

Then, update the connected linear object (eg, linear object A) of the facility (eg, N = PIVOT) to linear object B. (S580) Further, the distance information M and the sequence number of the facility (for example, N = PIVOT) are updated to new values M 'and SEQ'. (S590)

The management system 100 repeats the above procedure for the remaining facilities on the list L in steps S600 to S610 so that the distance information M and the sequence number of all the facilities on the list L Update.
