Description

Method for Calculating An Amount Of Materials

The present invention relates to a method for automatically performing a quantity calculation required for a ready-made work to be able to know the progress and progress of work in civil construction sites such as roads and complex construction.

First of all, it means the work of submitting the grounds for working for a certain period of time at the civil construction site in order to receive payment from the contractor according to the work history of the civil contractor for a certain period of time.

In this case, in particular, the earthwork is the most important problem because it refers to how much soil is cut and stacked in the existing ground, and accordingly, the amount of the dozer and the dump truck is determined and the amount of work is determined. Measuring the amount of change in earthwork is called quantity calculation.

That is, the quantity calculation required for the existing work that is currently performed on a monthly or quarterly basis is one section in which the long section is divided by a certain distance in a civil construction having a long section such as each section or station (in this case, a station or a road). Data is collected by hand (hereinafter, simply referred to as "station"), and the survey data are manually created on the blueprint drawings to calculate the area using a quadrature or the drawing work in a computer-aided design (CAD) program. After that, I am using the method of creating a loading table in a general text editor.

For example, after drawing the survey performance data on the design drawing, the method of calculating the area using a quadrature is explained as follows.

That is, the inflection point, which is the point where the terrain is changed, is checked, and the area is calculated by the closing ratio, and the average value is repeated three or more times as a whole. In addition, the obtained area is inputted in the document editing program again, and then the quantity performance is generated. At this time, the method of producing the volume performance using the quadrature as described above is the difference in the volume of the line thickness according to the scale, the difference in the volume in the operation of the archer, the difference in the amount of reading in the measurement line of the drawing, the difference according to the data input error And there is a problem that can not calculate the exact amount according to the difference in the user reading (when several people work in one drawing) and the like.

In addition, the quantity calculation method using a computer aided design (CAD) program requires drawing a survey line on a design drawing file (DWG file) and designating an area to draw an inflection point in the program and output the area. The work speed is relatively faster than the method of calculating the size, but it is cumbersome to input it into an Excel file, which is also a text editing program, to obtain the volume.

That is, the conventional method has consumed a lot of time because it has to go through all the work process by hand, and there is a problem in that it is difficult to progress because it requires a variety of tools and programs.

In addition, such a conventional method not only causes a lot of manpower and time waste, extends the construction period, but also affects the cost reduction, and the cumulative and cumbersome work accumulated by the employees loses efficiency and indolence. There is a problem that brings.

In order to solve the above problems, the present invention divides a construction section into a plurality of stations, but manages information about each station as a single station information file, and displays cross-sectional views according to survey values actually measured for each station. A quantity calculation method for calculating the area by outputting the station information file together on the original design drawing for each station and using the area information and each station information in the station information file to calculate a volume of a desired station section. The purpose is to provide.

In order to achieve the above object, the present invention provides a method for calculating a quantity applied to a surveying system, comprising: a first step of receiving station information on a road design drawing and generating a station information file (* .STL); A second step of generating a cross-sectional information file (* .SCT file or * .ESC file) by using surveyed survey values for a point corresponding to each station at a civil engineering site; A third step of inserting a survey line (cross section drawing) according to a survey value for a specific station in the cross information file on the cross section view of the specific station in the station information file (* .STL); A fourth step of calculating an area of a desired place after checking the closing of the cross section and the measurement line of the specific station; And a fifth step of calculating a volume for a desired portion of the station by using the station information of the station information file (* .STL) and the area information calculated through the fourth step.

On the other hand, the quantity calculation method according to the present invention can be largely applied to the road quantity calculation and only the quantity calculation, but there is no difference in the method that is basically carried out, the difference is that in case of only one station as in the case of road It is not organized into stations, but rather divided into blocks (cells). That is, in the case of a complex case, since the width is generally longer than the width of the road, it means that there are several drawings for one station. Therefore, the following description will mainly be described in the calculation of the volume of the road, it can be equally applied to the volume calculation of the complex.

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

In addition, the main terminal 30 calculates various quantities by using the survey value received from the surveying device 40 through a network or inputted through a storage medium 50 and a station information file input from a user. For carrying out, it includes a quantity calculation program for performing the function.

Meanwhile, hereinafter, the method for calculating the quantity according to the present invention will be mainly described as being implemented through the main terminal 30. However, the present invention is not limited thereto. Thus, the method for calculating the quantity according to the present invention is the personal portable terminal (or laptop). Computer (10) directly. That is, when the personal portable terminal (or notebook computer) 10 stores a quantity calculation program and a station information file for implementing the present invention, the quantity calculation method according to the present invention is carried out at the site of civil engineering. It may also be implemented directly via the terminal (or notebook computer) 10.

On the other hand, Figure 1b is an internal configuration of an embodiment of the main terminal to which the present invention is applied, the main terminal 30 to which the quantity calculation method according to the present invention is applied may be a general desktop computer (PC), As described above, notebook computers, personal digital assistants (PDAs) or other terminals capable of computing can be used.

That is, the main terminal 30, as shown in the figure, an input unit 33 for receiving information, a storage unit 35 for storing a quantity calculation program and input station information, etc. for implementing the present invention ), The quantity calculation program used in the present invention is executed by using the information collected through the interface 31, the interface, the input unit, and the storage unit for exchanging information with the surveying device (or network) via wire or wirelessly.

Will have the same configuration.

Meanwhile, FIG. 1C is a diagram for explaining a basic structure and a station of a road, and a road design drawing records information on a shape, curvature, distance, slope, width, and road depth of a road to be constructed (details thereof). (Not shown), the actual construction site divides the road design drawings as shown in Figure 1c for each section to create a cross-sectional view of each section, and then proceed with the construction substantially using the cross-sectional view of each section or I am making ready-made.

That is, FIG. 1C illustrates an example of a road design drawing applied to the present invention. As shown in the drawing, the road is perpendicular to the center point every 20 meters based on the center point A of the road viewpoint. The road was divided by a predetermined section across, and hereinafter, a line vertically crossing the road in the above will be simply referred to as a station (B).

At this time, each of the stations (B) is a reference of the survey in the quantity calculation method according to the present invention, for example, when the section from the start point of the road to the end point is divided into 10 stations After surveying the surrounding area on the basis of each cross-sectional view for to calculate the quantity for each station.

Meanwhile, in the case of the road design drawing shown in FIG. 1C, as described above, a station is set every 20 meters to divide a total of 200 m sections into 10 stations. It is also made based on the 10 stations. However, the length of 20 meters is an arbitrary number, and may be individually set according to the state of the terrain. That is, a station may be set every 10 meter intervals, and even if set at 10 meter intervals, a separate station may be set between two stations if necessary.

Hereinafter, as described above, the quantity calculation method required when preparing the ready-made roads will be described, and the same may be applied to the quantity calculation method required when preparing the ready-made roads.

2 is a flowchart illustrating an embodiment of a method for calculating a quantity according to the present invention, and FIGS. 3A to 3J are various exemplary views of a screen on which the quantity calculating method according to the present invention is implemented.

First, referring to Figure 2 briefly described the method of calculating the quantity according to the present invention.

That is, the first process of the quantity calculation method according to the present invention is to receive each station information on the road design drawing to generate a station information file (* .STL) (202). That is, as described above, the road design drawing (including the cross-sectional drawing for each station) for road construction only has information about length, depth, width, etc., but does not have information such as coordinates, ground elevation, etc. Therefore, the present invention In order to apply, the station number is received for each station of the road design drawing (original design drawing) and the station number is designated, and the necessary information such as coordinate information, ground elevation, plan height and scale for each cross section drawing is designated. It must be received and saved. On the other hand, in the design of the road, as described above by setting the stations at intervals of about 20M to create a ready-made, if the case of constructing a road of about 10Km as an example, at least 500 stations must be, each station is crossing A station information file (* .STL) is generated by receiving drawings and various information. That is, the station information file (* .STL) includes 500 cross-sectional drawing information for each of the 500 stations. Hereinafter, a case in which 500 station information is used to construct a road of 10 km will be described as an example.

After generating the station information file (* .STL) as described above, surveying is performed on the point corresponding to each station at the civil construction site to generate the cross-section information file (* .SCT file or * .ESC file). (204) In this case, conventionally, a method of acquiring a lateral survey value of 90 ° angle by moving the instrument to the center of each station is used, but in the quantity calculation method according to the present invention, it is possible to acquire terrain data of a station using a contour of the terrain. For example, by extracting coordinate values within the allowable range of the station and converting the coordinate value into the terrain data, the terrain data of the station can be easily obtained.

Next, a survey line (cross section diagram) according to a survey value for a specific station of the cross-section information file generated through the process 204 (ie, a cross section diagram generated according to a value actually measured for each station) ( In the following, a " measuring line " is simply inserted into the cross section of the station in the station information file (* .STL) (206). At this time, in the past, the measurement data measured in the field was drawn on a blueprint or by using a general CAD program, but the quantity calculation method according to the present invention is a survey line surveyed through the process 204 on the cross section of each station. It is automatically inserted to be drawn.

Next, after checking the closing of the cross section and the survey line for each station, the desired area is calculated (208). That is, it is possible to determine how much work has been carried out by calculating the area by merging the cross-sectional drawing on the station information file (* .STL) and the surveying line measured through the surveying process 204. On the other hand, the above method is generally applied to the first ready work by using the ground elevation and the survey line, and in the subsequent ready work, the survey line surveyed immediately before and the survey line surveyed through the current survey is closed. You can also track the progress of your work. That is, in the related art, a method of checking an inflection point using a quadrature or checking an area with an area function in a general CAD program has been used, but in the quantity calculation method according to the present invention, Soil, ripping rock, blasting rock, etc.) can be selected to display the total area immediately.

As a final step of the present invention, the volume is calculated and output (210). That is, although the volume was calculated by using an Excel program or a calculator (both section average method) in the related art, in the quantity calculation method according to the present invention, the station information input in advance and the area calculated through the process 208 are calculated. Volumes can be obtained simply and conveniently with data alone.

Hereinafter, each process described above will be described in detail.

As a first process, a process 202 of generating a station information file (* .STL) will be described in detail as follows.

First, station information is received and stored before generating a station information file (* .STL). That is, the coordinates, ground elevations (DL), plan heights (GL), scales (Scale) and storage paths of each cross-sectional drawing from the user through the input unit 33 while the cross-sectional diagram of each station is open (hereinafter, referred to as " , Simply called "station information" and save it. In this case, the method of receiving the station information may be classified into two methods, a method of directly inputting the drawing on the drawing as shown in FIG. 3A and a method of inputting through a dialog box as shown in FIG. 3B.

In this case, as shown in FIG. 3B, a method of inputting through a dialog box outputs a dialog box for inputting various station information for one station, and receives and stores necessary information in the dialog box.

On the other hand, in the case of the above example, each station information for 500 stations is received and stored through the above method.

Station information is input for each station as described above, and the 500 station information is made into one station information file (* .STL). 3C illustrates a process of receiving station information for two stations having numbers 120140 and 120160 among 500 stations to create a station information file (* .STL). That is, when 500 stations are received and stored through the above process, 500 station numbers are displayed in the right column (D) of FIG. 3C, and when the [Save Station] menu is selected, the 500 stations are displayed. The station information for a station is made into a single station information file (road.STL file).

Meanwhile, if the [Open Station Information] menu is selected for the station information file (* .STL), the station information for each station can be checked as shown in FIG. 3D. That is, FIG. 3D is an exemplary view of a screen outputting station information of a station having a station number 120140.

As a second process, a process of generating a cross-sectional information file (* .SCT or * .ESC file) by performing a survey on a point corresponding to each station at a civil construction site is as follows (204).

After generating (202) a station information file (* .STL) as described above, surveying is performed on a point corresponding to each station at a civil construction site to receive a survey value (204). In this case, conventionally, a method of acquiring a sine survey value of 90 ° angle by moving the instrument 10 to the center of each station is used, but in the quantity calculation method according to the present invention, the terrain data of the station is acquired using the contour of the terrain. It is possible to simply obtain the terrain data of the station by extracting coordinate values within the allowable range of the station and converting the coordinate values into the terrain data.

For example, a surveyor performs a survey by using a surveyor 10 at a civil engineering site, and the main terminal 30 to which the present invention is applied has a measurement value according to the survey as described above. Or through the input unit 33, and stores the input measurement value as a cross-sectional information file (* .SCT file or * .ESC file) using the station information file (* .STL).

That is, the control unit 32 of the main terminal 30 analyzes the inputted survey value with the information of the station information file (* .STL), and the station corresponds to the number of stations, and the center of the station. It calculates information about how much the left and right distance (offset) from the point is, and the ground height is stored as a cross information file. In this case, when the coordinate information of the surveyed station is out of the tolerance from the station, the surveyed station is not stored.

On the other hand, Figure 3e is an exemplary view showing the information on the station number, offset, ground elevation, etc. for all the stations surveyed through the above process, the cross-sectional information file (* .SCT file or * .ESC file) Information such as 3e is included. In this case, information about six stations is shown in FIG. 3E, where the station number 001 is a point belonging to the cross-sectional view of the first station of the road design drawing shown in FIG. 3A, and is located from the center point. It can be seen that it is 1M away in the + direction (right direction) and the ground elevation is 10M.

In other words, the survey value surveyed from the survey instrument 10 has only information about coordinates and ground elevation for each station, and the control unit 32 of the main terminal 30 stores the coordinate value of the survey value as the station information. By comparing the information of the file (* .STL) with each station, it is determined which station corresponds to the cross section of the station, and the station information as shown in FIG. 3E is converted into a cross-sectional information file (* .SCT file or * .ESC file). Will be saved as).

On the other hand, as described above, the measurement itself applied to the present invention can be performed using various methods conventionally used, except that the control unit 32 drives the quantity calculation program for implementing the present invention, each survey By comparing the value with the station information file, the survey value corresponds to the number of stations, and automatically calculates the left and right offset information and the ground height, and generates a cross-sectional information file (* .SCT file or * .ESC file). will be.

At this time, the types of survey values may be distinguished, for example, whether the survey values are rocky terrain or sedimentary terrain, and accordingly, different colors may be given to connection lines (that is, survey lines) of the survey values.

In addition, information about the number of ready-made cross information files to be prepared can also be input. That is, since the quantity calculation method according to the present invention is to be repeatedly performed at a predetermined time period as described above, it is necessary to clearly distinguish whether or not the cross-sectional file corresponding to the number of ready-made.

Meanwhile, as described above, a personal digital assistant (PDA) or a notebook computer on which the station information file (* .STL) is mounted is connected to the instrument 10 to receive a survey value directly from the instrument. The survey value may be stored as a crossing information file (* .SCT file or * .ESC file) using the station information file.

As a third process (206), the process of inserting a survey line for a particular station in the cross-section information file generated by the process (204) into the cross-sectional view of the station in the station information file (* .STL) Is as follows. That is, the present process uses the cross-section information file (* .ESC or * .SCT file) generated in the second process to convert the survey line (measured cross-sectional view) of each station into each station information file (* .STL). It is the process of marking on the cross section of the station.

That is, after executing the quantity calculation program on the main terminal 30 in which the cross information file (* .SCT or * .ESC) and the station information file (* .STL) are stored, the cross file batch menu is selected. When the desired station information file (* .STL) is selected, each station information corresponding to the station information file (* .STL) is displayed on the screen. In this case, select the desired station and then select the cross-sectional insert menu. As shown in FIG. 3F, the survey line (cross section diagram) surveyed through the second process is output together with the selected station cross section diagram.

That is, the control unit 32 reads and outputs the cross-sectional drawing E according to the design information of the selected station from the station information file (* .STL). The cross section (F) is to be read from the cross section information file (* .SCT or * .ESC) and output. In this case, although not shown in the drawings, it is also possible to output the cross-sectional drawing created at the time of the existing ready-made.

As a fourth process, a process 208 for calculating the area of a desired place after checking the closing of the cross section and the surveyed survey line (cross section) on the design drawing of each station is described as follows.

An area closure test is performed prior to area calculation.

That is, the cross-sectional view E outputted from the station information file (* .STL) among the cross-sectional views shown in FIG. 3F is manufactured by a drawing designer using a drawing creation program such as CAD. As shown in FIG. 3G, the seam g may not be completely closed, and in this case, since the complete area is difficult to calculate, the process of closing the seam of each line should be performed before calculating the area.

In this case, the region closing test as described above is performed when the [region closing] menu is selected in a state in which the drawing as shown in FIG. 3F to activate the area is activated. By finding and connecting the line that is closest to each other, all areas are closed.

On the other hand, when the area closing test is performed as described above, the controller 32 does not recognize each line on the drawing as an area concept of a CAD program (a polyline). Will be recognized as).

That is, after performing the area closing test, the user selects an area to obtain an area in FIG. 3F as shown in FIG. 3H, and the selected area H is activated by one polyline (light blue).

At this time, if the [area calculation] menu is input by the user, the control unit 32 calculates and outputs the area of the selected area by using the distance information according to the coordinate information on the drawing, and the output area information is the area information. Saved as a file (* .GPA). In addition, the area information file (* .GPA) may store the information on the area to be obtained together with the station information. That is, as shown in FIG. 3I, one station may be divided into a plurality of areas such as soil, ripping arm, blasting rock, etc., and the area thereof may be calculated and stored.

Meanwhile, the area of each part of the cross section is calculated through the above process for each station.

As a final process of the present invention, a process 210 for calculating and outputting a volume is as follows.

That is, the volume of the desired section can be obtained by calculating and storing the area of the cross section of each station through the process 208 and setting the section of the station to obtain the volume. In this case, since the area is separately classified and stored according to the soil, rock, etc., when calculating the area on the same cross section as described above, the volume calculation can be performed as described above. . Accordingly, the user can select the volume of the desired section by selecting the [Ships Table] menu among the menus of the quantity calculation program.

First, the user selects the [Site Table] menu as described above to obtain the volume, and at this time, the station number for which the volume is to be obtained and the quantity information to be output on the soil table (for example, earth and sand) , Partial components, such as a ripping arm, etc.), may be selected and input.

In this case, the controller 32 selects the selected station using the inputted information, each station section information of the station information file (* .STL), and an area information file (* .GPA) obtained through the fourth process. Volume information about is output as shown in FIG. 3J.

For example, when the volume between the first station and the second station is referred to as the volume of the first station, the controller 32 first generates the area information file (* .GPA) for the first station and the second station. While receiving the corresponding area information through the input, the distance between the first station and the second station through the station information file (* .STL) to receive the volume of the first station using the distance information and area information Will be.

In other words, the quantity calculation method according to the present invention as described above, by making a number of cross-sectional drawings required for the road design for each station to receive and store the information, while automatically measuring the surveyed value measured by the instrument After storing by dividing by station, insert the survey line (cross section drawing) according to the survey value on the cross section of each station, and after closing the surface formed by the cross section and the survey line, The volume is calculated using the separation distance between the stations and the area information so that the quantity calculation at the time of ready-made preparation can be performed automatically.

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 the excellent effect that it is possible to easily perform the calculation of the volume at the civil engineering site, the ready to be prepared monthly or quarterly when performing the civil engineering.

In addition, the present invention can automatically perform the area closing test for the CAD (CAD) drawings, there is an excellent effect that the area and volume can be obtained more easily.
