Description

Recording Apparatus for Architecture using the Laser Distance Measuring Machine and Recording Media of the Programm to activate the Measuring Apparatus}

The present invention relates to a building detecting device using a laser range finder, and more specifically, to compare and detect an error between a design drawing and an actual building length by comparing the length of the building measured using the laser range finder and the length shown in the drawing. The present invention relates to a building detection apparatus using a laser range finder.

In conventional construction and engineering supervision, field inspections have been carried out by carrying expensive equipment such as primitive measurement tools (tape tape), confirmation drawings, and optical diggers if necessary. However, these primitive measurement tools have a disadvantage in that a lot of time and expense are wasted because of the inconvenience of use and a lot of errors in the measurement is required to correct or supplement them.

To solve this problem, many small range finders have been developed, one of which is a laser range finder.

A laser range finder is a device that measures the distance between buildings according to the shape and time by which a laser beam is reflected. The laser range finder is compact and easy to carry, can measure distances of several meters to several tens of meters, and has almost no error compared to conventional measuring tools such as a tape measure.

The laser range finder has hundreds of memories, which can store a large number of measurement data, as well as the ability to calculate areas, volumes, etc. as well as distance measurements. You can also send and receive measurement data to and from your PC using an interface such as RS-232C.

However, even when using the laser range finder, the detector carried out the measurement by directly comparing the length displayed on the laser range finder and the length shown in the drawings while carrying a design drawing of the building or the plant separately.

The detector measures the distance to the components of the building shown in the drawing by using a laser range finder and compares the design length shown in the drawing to calculate how much error has occurred and how much the error rate is in the drawing. Had to be marked.

If the error between the drawing and the actual length is out of a certain level, it should be described in the drawing and a record must be kept for further action.

However, in a large apartment or plant construction site, the length of a large number of components must be detected, and this conventional method has a disadvantage in that a lot of time is wasted and the detection or supervision becomes formal.

In addition, the responsibility for post-problem becomes clear when the inspector leaves accurate information about the time and place of the inspector, but such information is rarely left because various information cannot be recorded by the conventional method. There is a disadvantage.

The present invention has been made to solve the above-mentioned problems, by comparing the length of the component measured by the laser range finder and the length of the component shown in the drawing to measure the construction error of the corresponding component in real time in the field An object of the present invention is to provide a building detection device using a laser range finder.

In addition, the present invention compares the design length of the component and the actual measurement length is displayed in red in the drawing when the error is large, and in the drawing is blue in the drawing when the error is small to easily determine whether the error of the length An object of the present invention is to provide a building detection device using a range finder.

In addition, the present invention provides a building detection apparatus using a laser range finder to wirelessly transmit and receive data between the laser range finder and the user terminal, so that the detector can be compared remotely without carrying the user terminal directly. For the purpose of

A description with reference to the drawings is as follows.

1 is a conceptual diagram showing an example of use of the building detection apparatus according to an embodiment of the present invention, will be described with reference to this.

The building detecting apparatus 100 using the laser range finder 100 includes a laser range finder 120 and a user terminal 140.

The laser range finder 120 refers to a device for measuring a distance by irradiating a laser beam, and includes all types of range finders capable of measuring a distance using a laser or the like and storing the data or transmitting the data to another terminal.

In addition, other types of range finders capable of measuring distances using ultrasonic waves or radio waves may be applied.

The laser range finder 120 is conventionally used as a conventional detection device, and its configuration and operation are not essential contents of the present invention, and thus detailed description thereof will be omitted.

The user terminal 140 stores drawing data and compares the measurement data input from the laser range finder 120 with the drawing data and displays the result.

The laser range finder 120 and the user terminal 140 may be connected by wire using a serial port or a USB port, or may be wirelessly connected using an RF frequency method.

In addition, methods for enabling data transmission and reception between two devices may be applied.

The user terminal 140 may be a PC, a notebook, a tablet PC, or the like. In addition, a processing apparatus capable of storing drawing data and displaying a drawing may be used.

2 is a structural diagram illustrating a structure of a user terminal according to an exemplary embodiment of the present invention, which will be described with reference to the figure.

The user terminal 140 includes a CPU 141, a memory 142, an output device 143, an input device 144, a drawing database 145, a measurement database 146, a data comparison module 147, and an error database ( 148).

The CPU 141 and the memory 142 control the operation and data processing of the user terminal 140.

The output device 143 is a device for electronically displaying a design drawing of a building or a plant, and a monitor included in a PC or the like is typical.

The input device 144 is a means for inputting measurement data about the building transmitted from the laser range finder 120 and selecting a component of the building to be detected by the user.

That is, when a detector inputs a selection signal for selecting a component to be detected from among a plurality of components included in the building, the detector transmits the selection signal to the CPU 141.

A device such as a touch screen may be used as an input device 144 at the same time as the output device 143 since the device may select a specific part of the drawing while simultaneously outputting the drawing of the building.

The drawing database 145 stores drawing data including information on a design drawing of a building or a plant. The drawing data includes information such as length, area, and angle of components included in a building.

Drawings of buildings that are generally used are created by CAD program. Drawings created by CAD program can be selected or separated by using the minimum lines for each line representing the component.

Thus, it is possible to compare the length of each line with the length between the components of the actual building that the lines represent.

The drawings included in the drawing data are divided into a plurality of cells having a predetermined area, and an identification code for identifying the plurality of cells is assigned to each cell.

The detector may select a portion to be detected by clicking a specific portion of the touch screen, or may specify a detection target by inputting an identification code of a specific cell through the input device 144.

The identification code is composed of alphabets, numbers, special symbols, etc. The size of the cell, the dividing line of the cell, the size and color of the identification code can be freely modified by the detector.

The measurement database 146 stores actual measurement data input from the laser range finder 120.

The actual measurement data is data obtained by measuring the length and the area of the component of the building using the laser range finder 120, and includes the name and location of the component, the date of inspection, the person in charge of the inspection, and other information.

Measurement data is stored and managed for each cell.

On the other hand, the detector may be stored together with the photo information or the voice annotation of the detector to facilitate the evaluation of the detection operation in the future. For this purpose, a digital recorder, a digital camera, a camcorder, or the like may be used. When calling the measured data stored for each cell, the video information and the audio information can be called together.

The data comparison module 147 compares the data about the design length of the building and the like included in the drawing data with the data about the actual measurement length included in the measurement data and calculates an error between the two data.

When the error between the drawing data and the measurement data for the component to be detected exceeds the predetermined range, the data comparison module 147 changes the color of the component in which the error occurs to red and outputs the actual measurement length. On the drawing.

In addition, when the error does not exceed a predetermined range, the color of the component is changed to blue to be output, and the actual measurement length is also displayed on the drawing.

When the building is completed, the construction is checked to see if it conforms to the design drawing. Actually, the range of errors that the completed building can have is determined, and the critical construction errors beyond the error are reconstructed or inspected.

Therefore, the detector can determine the range of the error in consideration of this, and the data comparison module 147 determines whether the range of the predetermined error is exceeded.

Through this operation, the detector can easily check the part where the error occurs and the part that is not in the drawing, and can easily find the target even when performing the follow-up action.

The error database 148 stores information on the error between the drawing data and the measurement data, wherein the identification number of the cell where the error occurred, the name of the part where the error occurred, the detection date, the detection person, the design length and the actual length, Information including the magnitude of the error, the ratio of the error, and the like is stored.

In addition, when reserving a follow-up action on a portion where an error occurs, information on this may also be stored.

The information on the error includes the date of the inspection and the information of the person in charge of the inspection in order to clarify the responsibility and facilitate the re-examination or correction in the event that the reliability of the inspection becomes a problem in the future.

Such drawing data, measurement data, error data, etc. may be converted into an Excel file, a word file, or a general text file, and selectively call or view data on a specific part of the data of the cell or the entire drawing.

As a method of measuring the distance of a building using the building detecting apparatus 100, there are a single person inspection, a double person inspection, or a majority detection method.

That is, one detector may carry the laser range finder 120 and the user terminal 140 connected by wire, and simultaneously perform distance measurement and comparison with the drawing.

Alternatively, the detector may carry the laser range finder 120 wirelessly connected to the user terminal 140 and measure the distance while moving in the building, and the administrator who manages the user terminal 140 receives and records data at a specific location. Detection can also be done in a concise manner.

In the state that the plurality of laser range finder 120 is connected to the user terminal 140, the distance is measured simultaneously in a plurality of locations, and transmitted to one user terminal 140 and stored so that the detection is performed in a faster manner. Detection will also be possible.

In the case of conducting the detection by wireless connection, a communication device for communication between the detector and the manager should be provided, and such communication equipment may be installed in the laser range finder 120 and the user terminal 140 itself. .

3 is a flowchart illustrating a detection method using a building detection device, which will be described with reference to this.

In order to detect a building or a plant, a detector inputs and stores data about a design drawing in a drawing database 145 of the user terminal 140. (S100)

The input drawing refers to drawing data created by a CAD or similar program and is divided into a plurality of cell units having a predetermined area.

The detector sets the environment of the laser range finder 120 and the user terminal 140 for detection.

Included in the configuration is the input port of the laser range finder 120, the range of tolerance and the display color of the drawing, the information of the person in charge and the name of the drawing, the display state of the grid, and the like, as well as information on the equipment used. do.

It is also possible to classify cells in units having an identification code for the drawings which are not divided in units of cells.

When the CPU 141 calls the drawing data stored in the drawing database 145 and displays the drawing data on the output device 143, the inspector checks the object (e.g., the length of the wall, Distance between the columns, height and width of the window, etc.) (S120).

The selection may be made by entering an identification number of a cell and a name of an element, or may be simply selected by clicking a corresponding element in a drawing displayed on an output device 143 such as a touch screen.

As described above, since the drawing is created by a program such as CAD, the entire component can be selected by clicking a certain position.

The detector places the laser range finder 120 at the selected position and measures the length of the measurement object. (S130) Data about the measured length is transmitted to the user terminal 140 via wire or wirelessly, and the measurement database 146 Are stored in.

After the detection is completed, the data comparison module 147 calls the data stored in the drawing database 145 and the measurement database 146, and compares data for the same component with each other (S140).

It is determined whether the error generated by comparing the two data is within the range of the preset error (S150), and if the error exceeds the preset range, it is recorded and stored in the error database 148 (S160).

In addition, in the drawing displayed on the output device 143, the portion where the error occurs is changed to red and the actual measurement length is displayed.

As a result of the comparison by the data comparison module 147, after recording the data on the error that does not exceed the preset range or exceeds the preset range, the specialty about the component to be detected is recorded to measure the measurement database. After the recording at 146, the detection is finished. (S170)

After measuring the distances to the three points of the starting point, the vertical point and the end point, the distance of the object to be detected can be calculated by the Pythagorean theorem.

By calculating by using the vertical distance to the wall, the distance to both end points, etc., it is possible to grasp the position where the laser range finder 120 is placed. In this way, the automatic calculation of the machine point coordinates is possible.

In addition, the laser range finder 120 can also measure the accuracy of the direct detection of firing the laser directly to measure the distance.

In addition, by expanding the method of indirect detection while rotating the laser range finder 120 horizontally, three-dimensional indirect detection will be possible.
