Description

Stakeout point derivation method based on computer-aided design method {DERIVATION METHOD OF SURVEY POINT USING COMPUTER AIDED DESIGN}

The present invention relates to a method for deriving a staked point based on a computer-aided design method.

In the conventional survey method, a surveyor surveys the current situation using a survey instrument (level) and a scale (prism) in the field, stores the survey information on a diskette, etc., and brings it to the design room, based on the survey information. As a result, the construction of roads or buildings, etc. was performed separately using a computer aided design (CAD) program. In this survey method, real-time parallelism between surveying and drawing was impossible. Therefore, recently, a surveying method using a virtual reference station (VRS), which can display information on a surveyed structure directly on a portable terminal using surveying information collected in the field through a surveying device, has been provided. . Recently, the term Network RTK has been used in a wide concept including a VRS server. That is, the network RTK refers to an RTK surveying method using a network, and examples thereof include VRS, MAX, and FKP.

Surveying and stakeout are used separately. Surveying is a commonly used method of surveying the current situation. It is mainly used to find out the current status of structures that have been constructed, and in the case of earthwork, to obtain quantities such as the area and volume of the spot. Stakeout is used for the purpose of displaying the coordinates in the drawing as a flag on the actual site in order to find out where to install the structure before constructing the structure.

When staked out, the user (survey) performs the display operation while moving to the stake out points corresponding to the coordinates on the drawing. In order to move to the desired stake out point, it is necessary to know the position of the stake out point before moving. Conventionally, a separate compass or the like was used to determine the location of the stake out point. However, in the case of using a compass, there is a difference between the true north and the magnetic north indicated by the needle of the compass.

The present invention is to solve the problems described above, when the stake out point is selected by selecting the entity (entity) on the CAD drawing output from the user terminal, and displays the relative position of the user relative to the stake point on the display screen of the user terminal The purpose of the present invention is to provide a method for deriving stakeout points based on computer-aided design method that enables users to move quickly and accurately to a desired stakeout point.

According to an aspect of the present invention, there is provided a method for deriving a staked point based on a computer-aided design method, the method including: executing a survey program mounted on a user terminal; Executing a coordinate stakeout menu included in the survey program to perform a coordinate stakeout; Activating a direction menu using the sun among a plurality of direction menus included in the stakeout window according to an execution result of the coordinate staked out menu; Receiving location information on a staked point on a CAD drawing output to the user terminal using the direction menu; And displaying a location of a user and a stakeout point and a separation distance between the user and the stakeout point on the CAD drawing.

According to the present invention, a method of deriving a stake out point based on a computer-aided design method may display a user's relative position with respect to a desired stake out point on a screen of a user terminal through a survey program installed in the user terminal. In this way, the present invention provides an effect that can dramatically increase the work efficiency by allowing the user to move quickly and accurately to the desired stake point without the hassle of correction compared to the prior art, and without the inconvenience of having additional configuration means. do.

The instrument 20 measures the height, length, coordinates, etc. of the structure in the civil construction site, or checks the coordinates of the drawings on the actual site in order to find out where to construct the structure before constructing the structure. It may include various types and types of surveying devices used to indicate. The instrument 20 includes a receiver 50 for receiving position information from the satellite 30 through a global navigation satellite system (GNSS).

The user terminal 10 communicates with the instrument 20 by wire or wirelessly. The user terminal 10 receives survey information through communication with the instrument 20. The user terminal 10 incorporates a survey program to visually display survey information.

The survey program is based on computer aided design (CAD). Computer-aided design (CAD) uses design information stored in a computer such as a user's terminal to allow a user to draw a map or various types of structures while viewing the screen, and output the drawn map or structure on the screen. It's a way to do it.

Because the survey program is implemented based on computer aided design (CAD), the corrected survey information can be displayed on the CAD drawing in various forms. In addition, the survey program may provide editing and output functions such as status line connection and text notation, and various types of symbols may be input on a CAD drawing through a user. In other words, the survey program applied to the present invention is a CAD program supporting computer aided design (CAD), which combines a survey-related program with various survey information including coordinate information of a structure surveyed by the survey instrument 20. Not only can be displayed in the CAD drawing, but can also provide a function to edit it in various forms. In other words, the survey program applied to the present invention displays various structures on the drawing using survey information, and not only displays the structures graphically, but also displays the structures on the CAD base to enable various editing and application. It has the feature of being able to display.

In particular, the survey program applied to the present invention finds and automatically accesses a mount point that can communicate with a VRS server when a traffic jam such as a congestion of traffic, a traffic limit, etc. occurs with a network RTK server. It includes a function of displaying the status. Since the communication connection between the user terminal 10 and the Network RTK server is very simple through this survey program, the work efficiency is greatly improved as compared with the user's conventional access.

The user terminal 10 carrying the survey program as described above may be manufactured in various types of electronic devices, and in particular, may be manufactured by a personal digital assistant (PDA). The user terminal 10 indicates a portable device capable of collecting, storing, creating, searching, and communicating information.

2 is a diagram illustrating an internal configuration of a user terminal 10 illustrated in FIG. 1.

As shown in FIG. 2, the user terminal 10 includes an input unit 13 for receiving various types of information, a storage unit 15 for storing a survey program and survey information, an instrument 20, and a wired or wireless (Bluetooth) device. Control unit 12 and control unit for executing a survey program using the information collected through the interface 11, the interface 11, the input unit 13, the storage unit 15, etc. And an output unit 14 for outputting various result information executed through 12.

The method of surveying and transmitting in the user terminal 10 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.

At this time, the survey program applied to the present invention is characterized in that it is configured based on a computer aided design (CAD) method as described above. In other words, as described above, conventional surveying programs merely collect survey information transmitted from the instrument or sketch it in a simple form based on the collected survey information. The inconvenience of having to enter the survey information after executing the support design program. However, the survey program used in the present invention has a feature that, based on a computer-aided design (CAD) program, survey related programs are combined, so that survey information can be displayed and edited in various forms.

In addition, the survey program applied to the present invention is characterized by having a function of displaying the relative position of the user to the desired stake point on the screen of the user terminal, including the coordinate stake out function. Through this surveying program, the present invention allows the user to quickly and accurately move to a desired stake point without the hassle of correction and the inconvenience of having to provide additional configuration means (for example, a compass). Greatly increase

FIG. 3 sequentially shows a process of deriving a stakeout point and a user's position on a CAD drawing using a surveying program in a method of deriving a staked point based on a computer-aided design method according to the present invention. 4 to 6 are exemplary views corresponding to each step of FIG. 3.

Referring to FIG. 3, in the method of deriving a staked point based on a computer-aided design method according to the present invention, a survey program is executed by a user's command (S10). The main screen of the user terminal 10 to which the present invention is applied is as shown in FIG. 4. The user terminal 10 to which the present invention is applied is equipped with a survey program. The user (surveyor) clicks and executes a survey program on the main screen through an input unit of the user terminal.

The screen output when the user executes the survey program is shown in FIG. 5. FIG. 5 shows an example of a survey program executed through a user terminal, and it can be seen that the CAD program is executed as described above. As shown in FIG. 5, the survey program includes various main menus such as 'File', 'View', 'Edit', 'Settings' and 'Status', and each of the main menus can perform various functions again. It contains detailed menus.

In accordance with the present invention, the method for deriving a stake out point based on a computer-aided design method executes a 'stake out stake' menu according to a user's command to derive the stake out point and the user's position (S20). 'Coordinated stakeout' may be included in the 'status' menu as a detailed menu as shown in FIG.

When the 'stake out stake' menu is executed, a message 'Please enter the stake out point:' appears on the lower menu bar of the display screen of the user terminal as shown in FIG. In this case, the user may directly input the coordinate information of the stake out point, when the stake out point is shown in the CAD drawing the station number (indicated by '1' and '5' in Fig. 5A) of FIG. You can select a stake out point by typing (B) and pressing the Enter key, or by clicking on an entity (such as a point or line) in the CAD drawing directly with the stylus pen. . As such, when the stake out point is inputted to a station number output on the CAD drawing or directly selected from an entity on the CAD drawing, the stake out window is displayed as shown in FIG. 5C.

In this case, the user may select any one of three direction types from the 'direction' menu located at the lower left of the stakeout window. Among the kinds of directions, 'movement' indicates the stakeout point and the user's position based on the user's moving direction, and 'north' refers to the 12 o'clock direction of the user terminal as the north, and the stakeout point and the user based on the direction. The position of is to appear, the 'sun' is to show the location of the stake out point and the user relative to the direction of the sun. In view of the accuracy or promptness of location derivation, it is more preferable to select 'sun' than to select 'movement' or 'north' (S30). That is, since the location information of the sun by measurement location and measurement time can be fixed to a certain value, deriving the stakeout point and the user's location based on the direction of the sun can greatly secure the speed and accuracy. do.

5 (C) shows the relationship between the stakeout point and the user's separation distance (13.279) and relative position when the 'sun' is selected. To reach the desired stake out point, the user moves along the arrow toward the circle center until the separation distance is zero. For example, if the 12 o'clock position is set to the position of the sun on the screen of the user terminal output unit, and the user places the 12 o'clock position of the user terminal on the same line as the position of the sun, the control unit is the current time, By using the position, the position of the sun and the position of the stake out point is output the direction and distance that the user should proceed toward the stake point based on the sun direction (12 o'clock direction).

In the computer-aided design method based stakeout method according to the present invention displays the location of the user and the stakeout point and the separation distance between the user and the stakeout point on the CAD drawing (S40). If you click on the 'drawings' menu on the bottom left of the screen of the stake out window as shown in Figure 6 (A), as shown in Figure 6 (B) the actual position of the user and the stake out point is indicated by a red arrow on the CAD drawing It can be seen that the actual separation distance is displayed on the CAD drawing. Meanwhile, the user may perform the stakeout operation based on the location information displayed in the stakeout window or the CAD drawing according to the situation. In addition, when the 'ESC' key located in the lower middle of the CAD screen shown in FIG. 6B is pressed, the screen of the user terminal is changed to FIG. 6A. That is, the user may go to the stake point while alternately or simultaneously checking the CAD drawing and the map while floating the map for finding the stake point on the CAD drawing.

When you want to stake out the next station immediately in the stake out window as shown in Figure 6 (A) it is to activate the 'stake out point' menu located on the upper left. In this case, enter the station number in the 'Enter the stake out point:' on the lower menu bar of the CAD screen as shown in FIG. 6 (C), or click the next stake out point directly with a stylus pen. The distance value / direction for the next point is indicated as shown in. When the user inputs the stake out point at the bottom of the CAD screen of FIG. 6 (C), the user returns to the stake out window as shown in FIG. 6 (A), and the user can perform the stake out operation based on the information displayed in the stake out window. Will be.

As described above, according to the present invention, the method for deriving a stake out point based on a computer-aided design scheme may display a user's relative position with respect to a desired stake out point on a screen of the user terminal through a survey program installed in the user terminal. . Through this, the present invention can significantly increase the work efficiency by allowing the user to move quickly and accurately to the desired stake point without the hassle of correction compared to the prior art, and without the inconvenience of having to provide additional configuration means.
