Description

{Method For Auto-Making A Topography}

The present invention relates to a method for automatically creating a state diagram and contour lines using surveying point information at a construction site.

The conventional survey method is that after the surveyor goes out to the field to survey the land using a level and a prism, the surveyor stores the station information in the field, or stores it in a memory card of the instrument. The design was brought to the design room, and a road design was constructed using a computer aided design (CAD) program or the like based on the point information.

However, the conventional point information as described above simply includes general information about the coordinates and the ground elevation of the surveyed area. Therefore, in order to generate complex drawings such as the current state map and the contour line using the point information as described above, the memo for each side is memorized. By manually inputting the CAD drawing manually, there was an inconvenience of creating a current state map by querying the code of the inputted point on the CAD.

In addition, in the conventional survey method as described above, since various types of drawings created by using the point information can be managed only individually, a plurality of drawings created by using the point information cannot be managed collectively. There was this. That is, the user can create a plurality of drawings, such as the current state diagram, contour lines, vertical and horizontal drawings of the complex and the road, by using the point information file. In this case, there was a problem in that cumbersome processes had to be performed. For example, in the case of modifying the point information file, the current state diagram created using the point information file needs to be called and corrected again, and similarly, the contour drawing created using the point information file needs to be called again and corrected. There was a ham.

The present invention for solving the problems as described above, by assigning a code necessary for the current state map and contour line based on a user-defined list of the surveyed point value in the field of use to manage the point information, the point information during the office visit Provides a method for automatically creating a status diagram to automatically create a status diagram and contour lines based on a user-defined list, and to manage a plurality of drawings created using the point information as a project file. Its purpose is to.

According to the present invention for achieving the above object, in the present state diagram automatic generation method applied to the surveying system, according to the survey point value (N, E, Z value) and the user-defined list for creating the state diagram from the instrument 20 A first step of receiving and storing point information including P code information assigned to the measured value; A second step of receiving a state diagram creation request for a plurality of point information inputted through the first step; According to the current state diagram preparation request, the station value (N, E, Z value) of the station information is extracted, and the code (P code) given to the station value is compared with the user-defined list to compare the code (P). extracting information meant by code); A fourth step of outputting the point value on the drawing and outputting content corresponding to the extracted information of the code (P code) on the drawing; And a fifth step of creating a current state diagram by repeatedly performing the third and fourth steps with respect to all the stored point information, wherein the information represented by the code of the third step is And at least one of an item of a code, a symbol name, a symbol mark, a ground height, a status line connection, a symbol sequence, a scale, a rotation, and a closure, and the displayed information is displayed on the drawing through the fifth step. It is characterized by outputting.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A is a configuration diagram of an embodiment of a surveying system to which the present invention is applied, and FIG. 1B is a configuration diagram of an embodiment of a personal computer to which the present invention is applied.

First, a surveying system to which the present invention as shown in FIG. 1A is applied includes a surveyor 20 for performing surveying at various civil works sites and a personal computer for executing an automatic drawing method according to the present invention. 10) is configured to include.

In this case, the personal computer 10 may be a desktop computer and a notebook computer. Notebook computers are preferable given their use in the survey site. Therefore, in the following description, a desktop computer and a notebook computer are collectively referred to as a personal computer 10 except when performing a survey at a survey site (in this case, a notebook computer is used as the personal computer 10).

In addition, the personal computer 10 may not only receive information on the point surveyed from the instrument 20 from the instrument 20 directly through wired or wireless communication as shown in FIG. If you are at a distance, you can receive via wired or wireless networks. In addition, when the personal information 10 is stored in a portable storage medium 30, such as a floppy diskette, a compact disk (CD) or flash memory, surveying information surveyed at the survey site through the reader of the storage medium; Station information may also be input.

Next, FIG. 1B is an internal configuration diagram of a personal computer to which the present invention is applied, and the personal computer 10 to which the present invention is applied has the same configuration as a general personal computer.

That is, the personal computer 10, as shown in the figure, an input unit 13 for receiving information, a storage program for storing the surveying program and the surveyed point information for implementing the present invention, etc. And a control unit for executing the survey program used in the present invention by using information collected through the interface 11, the interface, the input unit, and the storage unit for exchanging information with the instrument (or network) via wire or wirelessly. And an output unit 14 for outputting various results executed through the control unit.

That is, the method for automatically generating a present state diagram according to the present invention is implemented by a survey program stored in the storage unit 15, and the survey program is executed under the control of the controller 12.

In this case, the survey program is implemented based on a computer aided design (CAD) program, so that various status data required based on the survey data can be input, modified, and output in various forms. In addition, although the survey program may be used when performing a direct survey, the survey program may be used to automatically create a current state map, contour lines, a complex, and a road design using the surveyed survey information.

In other words, the present invention may receive the point information directly through the surveying device 20 in the field, and automatically generate the present state map, but the nature of the personal computer (convenience of movement) is measured rather than surveying in the field. It is preferable to apply the method to automatically generate the present state map by receiving point information (N, E, Z, P Code).

Accordingly, the personal computer 10 receives the surveying information surveyed in the field through a wired / wireless network through a personal digital assistant (PDA) or other communication terminal, or a portable storage medium 30 or a surveying device storing the survey data as described above. It is input through.

Hereinafter, a method for automatically creating a current state diagram according to the present invention implemented through the survey program will be described by dividing into four parts as shown in FIG. 2.

2 is a flowchart illustrating an embodiment of a method for automatically generating a status diagram according to the present invention.

That is, the first process is a process of receiving the survey information from the instrument through various paths as described above (100).

The second process is a process of automatically generating a state diagram in which various related points are connected to a state line, and various symbols and characters are displayed (200).

A third process is a process of displaying contour lines on the drawing by forming a triangular network by applying a break line using the point information (300).

Finally, the fourth process is a process of creating a project file to collectively manage information created in the survey program using the state diagram information, contour information, and other point information generated using the same point information (400). .

That is, the present invention is based on the automatic creation method of the present state diagram, and includes a contour creation method and a project file creation method.

FIG. 3 is an exemplary view of a user-defined list used in a station information input process in a method for automatically generating a state diagram according to the present invention, and FIG. 3 is a diagram of a user-defined list file used in the point information input process 100 shown in FIG. 2. An example is shown.

First, as described above, the surveying program for implementing the automatic present state map generating method according to the present invention is mounted in the storage unit 15 of the personal computer 10 and executed. It is input through various paths as shown.

Hereinafter, various paths for receiving point information from the personal computer 10 will be described. In this case, the station information refers to information consisting of the coordinates of the station, the ground elevation, and the station code, and the station information for a plurality of stations is one station information file [* .NEZ, * .ELT, * .ENZ, etc. ] Can be managed.

First, there is a method of inputting station information by direct surveying. That is, as mentioned in the description of FIG. 1A, after the personal computer 10 is connected to the instrument 20 at the survey site, measurement information is transmitted from the instrument in real time.

At this time, the process of receiving the point information by the survey in more detail as follows.

First, the instrument 20 is set up at a position to be surveyed, the personal computer 10 is connected to the instrument 20, and then a survey program driven by the personal computer 10 is executed to execute the survey program 20. Enter the instrument point coordinates, azimuth, prism height, and instrument height.

Next, the poleman is moved to the position to be measured and the measurement is performed by the instrument 20.

In this case, when the measurement is performed by the instrument 20, a distance and an azimuth angle between the mechanical point and the pole man can be obtained. The instrument 20 uses these two values and the machine point coordinates to determine the station value of the pole man position (N, E). , Z value) to be transmitted to the personal computer 10 via wire or wireless.

On the other hand, after the user executes the survey program on the personal computer 10 and before receiving and storing the point information, the user may draw a desired state diagram based on a 'user-defined list' as shown in FIG. 3. You will be prompted to enter the code. In this case, the 'user-defined list' includes all symbols provided by the National Geographic Information Institute (NGIS) and has various forms of connection of the present line.

That is, when the user stores the station value (N, E, Z value) transmitted from the instrument 20, the code to be assigned to the station value (for example, 'AAB001' or 'R') with reference to FIG. Etc. (hereinafter, simply referred to as "P code") are selected and stored together. At this time, the measured value and the P code are stored in a file (* .NEZ file, etc.) as described above. Hereinafter, the information including the station value (N, E, Z value) and P code will be referred to as station information.

Meanwhile, the 'user-defined list' illustrated in FIG. 3 is managed as a separate file (hereinafter, simply referred to as a "user-defined list file"). The items will be described below.

First, the code (that is, P code) is a standard schematic code of the National Geographic Information Institute (NGIS), and the principle of displaying the status diagram for the code is controlled by the items indicated by 1 and 0. In other words, it is activated in case of “1” and inactive in case of “0”.

In addition, since the user code start item has a different name for assigning a P code to a site and a company, the P code used at each site and a company is replaced with the standard schematic code.

In addition, when describing each item, "symbol name" refers to a symbol name for the code, except for "starting user code", and assigns the same name as the code, and otherwise (user code start corresponding column). The code should be a user defined code name in the "Code" field and the standard schematic code of the National Geographic Information (NGIS) in the "Symbol Name".

In addition, the description may include a name or description to describe the symbol. “Symbol” should be written as “1” if the symbol is marked for the code, or “0” if not indicated. As in the above description, the “Geometric Heights” should be written as “1” when marking the elevation, and “0” when not indicated. The “status line” should be marked as “1” when connecting to all points and present lines with the same code, and “0” otherwise. "Symbol continuation" can be used to represent symbols at continuous regular intervals such as barbed wire, fence, and stonework. “Scale” is the part that determines the size of the symbol, so the user should keep in mind that the CivilPro symbol is sized to fit the 1/1000 drawing, and should be scaled for other scales. "Rotate" is used to rotate the symbol. Finally, the “close” item is used when a line such as a house, block, or fence wants to close.

That is, the station information inputting the P code to the station value through the above-described process is stored in the personal computer 10, and the above operation is repeatedly performed for each measured station value.

Second, there is an input method through a wired or wireless network. That is, when the personal computer is connected to a wired or wireless network, first, the surveying device of the surveying site transmits the surveying point information through the wired / wireless network using a terminal capable of communication, and then the personal computer ( 10) is connected to the wired or wireless network to receive the point information.

Third, there is an input method through a portable storage medium. In other words, first, the surveying device for the portable storage medium 30 is stored in the portable storage medium 30, such as floppy diskette, compact disc (CD) or flash memory, by the instrument of the survey site stored in the survey information by the method described above; Is connected to the personal computer 10 to receive the point information.

That is, according to the present invention, a method for automatically generating a present state map includes a present state map, contour lines, a complex, a road design, and a project using the point information input by the above method in the personal computer 10 having the survey program. It relates to how to perform tasks such as file creation.

4A to 4D are various screen configuration diagrams used for the status map creation process among the automatic status map generation method according to the present invention, and various screen configurations for explaining the status map creation process 200 shown in FIG. It is shown.

First, FIG. 4A illustrates a state in which a point information file (for example, a * .NEZ file) stored through the process described with reference to FIG. 3 is opened through an 'open' menu on the survey program. It can be seen that only basic information (N, E, Z values) of the station is displayed as shown in FIG.

In this case, click each station with the mouse (or position the mouse on the station, or right-click the mouse on the station and select View Information from the menu that appears) or use the 'Search Station Information' menu for the station. Various information, for example, the N, E, Z value, P code information and information about the side number may be activated to appear.

On the other hand, a user selects a menu for automatically creating a status diagram of the survey program while the point information file is opened, and the control unit 12 selects the point in the user-defined list file as shown in FIG. 3. After extracting the item corresponding to the P code of the information, the current state diagram is automatically created according to the contents defined in the above item.

That is, the control unit 12, after acquiring a symbol (symbol name) among the items corresponding to the P code of the point information in the user-defined list file, whether the symbol is marked (0-notation, 1-symbol notation) ) And whether the ground height [Z] is marked (0 not indicated, 1- ground height [Z] notation) and output.

In addition, the control unit 12, whether the present status line is displayed through the items (if there is a station of the same code consecutively connected all points and the present status line, 0-not connected, 1-status line connection) and symbol continuous It is determined whether or not to display the symbols acquired at regular intervals, not 0-notation, and other symbol-integer intervals.

In addition, the controller 12 extracts information such as scale (size of the marked symbol), rotation (rotation of the marked symbol), closing or not (0-closing, 1-status closing) through the items. It will be printed on the drawing according to the item.

On the other hand, the control unit 12 outputs the corresponding contents according to the item contents as described above for one point, and repeats the above operation using another point information, for all the point information After performing the above operation will be terminated.

An example of a state diagram created through the above process is illustrated in FIG. 4B.

Meanwhile, FIG. 4C is an enlarged part of the present state diagram shown in FIG. 4B, and the information known from the present state diagram will be described below with reference to FIG. 4C.

That is, when querying the information of one of the points (A) of the plurality of points shown in Figure 4c, it can be seen that the side number (PNo) of the station (A) is 87, P code is L.

At this time, if you check the P code L in the user-defined list file (Codetemp.txt) shown in Figure 3, it can be confirmed that the data shown in Table 1 below.

That is, in the case of the point A, the street lamp AE141 is inputted as the scale 1, and the ground elevation is also indicated, and the contents defined in the user-defined list (Codetemp.txt) shown in FIG. 3 are automatically displayed. It can be seen that it is written in the drawing as it is.

In the following description, a method of connecting the current status line in the automatic creation of the current status will be described in detail with reference to FIG. 4D.

That is, as described above, a P code is assigned to the point information, and a current line is connected to the points having the same P code based on the closed status information.

In this case, conventionally, in assigning a P code to the closing points as shown in FIG. 4D, since only one P code may be assigned to one station, the overlapping point may be measured twice to each station. According to the code assigned, the status line is automatically connected. For example, by assigning each P code to each of the closed groups (Groups A and B), in the case of overlapping points (points 3 and 4), the P code assigned to each group is determined by two surveys. (A, B) is given. In other words, it was inconvenient to perform two surveys in order to assign a code designated in each group to the current line connection.

However, in the present invention, as shown in FIG. 4D, the P code is assigned to the stations 3 and 4 by combining the A code and the B code (A + B), thereby providing two overlapping points for the current line connection. It is possible to obtain the necessary status line with a single measurement without measuring.

That is, when measuring points 3 and 4, when the P code for the points is input in the form (A + B), the controller 12 has the points having the A code and the B codes. By identifying the points common to the stations, each status line is automatically connected according to each code when creating the status line.

As described above, the method for automatically generating a present state diagram according to the present invention automatically creates a present state diagram using the point information measured by the instrument 20, and also duplicates the work in connecting the present state lines of the present state diagram. It can be omitted.

5A to 5F are various screen configuration diagrams used for the contour line creation process among the automatic state diagram creation method according to the present invention, and show various screen configurations for explaining the contour line creation process 300 shown in FIG. .

That is, the method for automatically generating a present state map according to the present invention is implemented through the survey program, and includes a method of creating a state map as well as a contour line as described above. Hereinafter, referring to FIGS. 5A to 5F. I will explain how to create contours. At this time, the contour line means that a point having the same height is connected with a line by using a triangular network constructed based on the point information.

On the other hand, in general, a method of creating a contour line using the triangular network after forming a triangular network using the point information is used. However, the present invention is characterized by the fact that it is possible to create a contour line that is more similar to the actual shape by constructing a contour line through a break line by using the current state map created through FIGS. 4A to 4D after constructing a triangular network using the point information. have.

In order to prepare a contour line, first, the control unit 12 constructs a triangular network by using point information of the point information file.

In other words, triangulation is an initial step of contour creation, and triangulation is constructed based on one point and a neighboring point. At this time, the reason for constructing the triangular net is to automatically calculate the ground elevation of each area by equally distributing the ground height difference between the station and the station. On the other hand, Figure 5a is an example of the triangular network is configured by the control unit 12 by selecting the [triangular network configuration] menu of the [contour contour creation] menu on the survey program is output through the output unit 14 It is shown.

When the triangular net is configured through the above process, the brake line is configured next. At this time, the break line creation process is intended to draw the contour line most similar to the actual terrain.

That is, the break line creation is for keeping one side of a triangle of a triangle network on a designated line so that the triangle network does not pass, and is mainly applied to a place where the elevation changes constantly. At this time, Figure 5a shows a triangular net is not subjected to the above-described break line creation process, Figure 5b shows a triangular net changed by the application of the break line as described above, as shown in the figure It can be seen that the sides and the brake lines of the do not overlap. In addition, FIG. 5C illustrates the change of the contour line when the contour line is made and the rough line is not subjected to the brake line process as described above.

On the other hand, the brake line application process as described above with reference to Figures 5d to 5f in more detail as follows.

In other words, if the present state data for the retaining wall is described as an example, the present state diagram is as shown in FIG. 5D. That is, the present state line shown in FIG. 5D represents a retaining wall, and the left side of the retaining wall represents an altitude with an elevation of 5, and the right side of the retaining wall represents a low elevation with an elevation of 1.

At this time, if the triangular network is configured by using the four points shown in Figure 5d is configured as shown in Figure 5e. However, in the triangular network shown in Fig. 5E, the ground height of the retaining wall A point is calculated as three. Because the ground elevation appears to be placed between the 5 and 1 stations. However, if the present state diagram of FIG. 5D is confirmed, it can be confirmed that point A is the middle point of the retaining wall and the ground height is five. Therefore, when contour lines are drawn using only the triangular network obtained through Fig. 5E, data different from the actual shape is inevitably obtained.

On the other hand, when the triangular network is configured by applying the current line (retaining wall) shown in FIG. 5D as a brake line as in the present invention, the triangular network is configured as shown in FIG. 5F and the height of the A point is 5 as shown in the current state diagram. It can be found.

That is, the brake line application process is a process for drawing contour lines close to the actual shape by absorbing the current line of the current state diagram as one side of the triangular network.

On the other hand, the user can set whether to display the contour line in two or three dimensions when outputting to the output unit (14). At this time, if the default value is set in advance in 2D or 3D, the above setting process can be omitted.

The user can also select the curve of the contour. In other words, the contour curve can be defined from 0 to 10. If the curve is 0, the polyline is drawn with a hard feeling without the curve. In this case, in general, when the contour of the contour is selected to about 2 to 4, the contour can be made to look good without twisting.

As described above, when the user configures a triangular network through the point information file and performs a breakline creation process, when the user selects the [contour drawing] menu among the heavy menus, the control unit 12 includes the triangular network configuration information and The contour line is created using the break line information, and the generated contour line is output through the output unit 14.

Meanwhile, hereinafter, the project file creation process 400 shown in FIG. 2 will be described in detail.

The user can not only make the present state map and contour line by using the present state automatic drawing method according to the present invention as described above, but also the longitudinal cross-sectional drawing of the complex and the road (hereinafter, simply referred to as the "cross-sectional view"), etc. I can write it.

That is, the user can open a single point information file and generate a plurality of drawings, such as a current state diagram, a contour line, and a vertical cross section drawing, wherein the current state map, contour lines, and vertical cross section drawings, respectively, are separate drawing files. Can be stored.

On the other hand, if the individual management of each of the drawing files when the modification and editing work is to occur the problem as mentioned in the description of the prior art, in order to solve this problem in the present invention, each of the drawing files It can be managed by creating a project file of.

The process of generating the project file as described above is as follows.

First, a state diagram file, a contour file, a longitudinal drawing file, a cross-sectional drawing file, and the like generated through the survey program are stored in a folder in which a project file is generated. At this time, the number of drawings to be stored is not limited, but it is preferable to store about four drawing files due to the limitation of the screen size of the output unit 14.

When the drawing file is stored through the above process, the user selects the [Save station file] menu of the survey program (because a station information file (* .NEZ file, etc.) is required to manage the project file). The station information file used by the drawing files is stored in the folder.

On the other hand, when storing the point information file, a message window for querying whether to generate a project file is activated on the screen of the output unit 14, and presses [Yes]. Project files (* .CPJ) with file paths for files, contour files, profile drawing files and cross-sectional drawing files, etc.) are stored in this folder.

That is, a project file named [* .CPJ] is created and stored in the folder with the same name as the point information file (* .NEZ), and when the project file (* .CPJ) is opened in a notepad, it is combined into a project. It can be seen that information on the paths of the respective drawing files is input.

In other words, the folder uses the respective drawing files (status file, contour file, profile drawing file and cross-sectional drawing file, etc.) and a project file (* .CPJ) for managing the drawing files. The point information file (* .NEZ) being stored is stored, and the respective drawing files by the project file (* .CPJ) as described above are collectively managed.

Meanwhile, when opening the point information file (* .NEZ) stored together with the project file (* .CPJ) in the folder, a message asking whether to open the project file is displayed on the screen of the output unit 14. do.

At this time, if a menu of "Yes" is selected, the controller 12 refers to the project file (* .CPJ), and the drawings (status diagram file, contour file, longitudinal drawing file) stored by the project file. And cross-sectional drawing files, etc.) are output through the screen of the output unit 14, and thus, the user can manage a plurality of drawing files stored as project files through one screen. Interworking between drawings according to the regeneration of the data, data modification and plan modification can be performed easily.

On the other hand, if a menu of "no" is selected, the controller 12 outputs only the point information file (* .NEZ) through the screen of the output unit 14.

That is, the present invention as described above, by assigning the P code to the point information surveyed through the instrument, it is not only able to automatically create a state diagram and contour lines, but also created state diagram file, contour file, longitudinal drawing file and traverse It provides a method to manage drawing files and the like as a project file.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

The present invention as described above has an excellent effect of automatically generating a variety of complex status maps and contour lines using the point information measured by the instrument.

In addition, the present invention provides a function to manage the status map file, contour file, profile drawing file, and cross-sectional drawing file created using the point information as one project file, so that the user can easily modify the drawing files. And good management.
