Description

[0001] The present invention relates to a safety inspection apparatus for a civil engineering structure using a digital camera,

The present invention relates to a method of operating a safety inspection system for a civil engineering structure using a digital camera for diagnosing a displacement of a structure by analyzing an image of the exterior of the structure, and more particularly, The image is uploaded to the safety diagnostic terminal and the safety diagnostic terminal analyzes the displacement using either normal AUTO CAD, photoshop or illust program, It is economically advantageous not to use the program, and it is possible to accurately determine the abnormality such as the displacement of the civil engineering structure. Also, by the weight including the digital camera and the fixing part, And is rotated by a deceleration motor when the rotating body rotates Using a digital camera to facilitate relates to an operating method of the civil engineering structures safety inspection device.

Artificial structures formed of naturally formed natural structures, civil engineering, and architectural structures, especially large buildings and bridges, are generally verified for safety through thorough supervision from design to completion, and periodic safety diagnosis after completion.

In the following description, the civil engineering structure or structure will be described as including civil engineering structure, building structure, artificial structure, and natural structure.

All structures are built well, and even after passing safety diagnosis safely, they are always in danger of collapsing due to various causes of internal and external use during use.

In order to prevent structural collapse and large-scale disasters, it is necessary to always provide a surveillance and alarm system capable of promptly taking measures such as evacuation, suspension, etc. in case of displacement, obstacle, .

General safety diagnosis methods of these structures include non-destructive testing (NDT) such as radiation penetration and ultrasonic inspection in addition to the most basic appearance inspection, and it is possible to precisely diagnose the safety of the structure through such non-destructive inspection .

These nondestructive tests are necessary for safety diagnosis on a regular or irregular basis after the construction process and construction, but they are generally not suitable as an ongoing monitoring means. In other words, the nondestructive inspection must be carried out in a very wide variety according to the characteristics of the structure, it must be done by experts in each field, and it takes a long time to prepare and diagnose for the inspection.

In addition, there is no need to consider the economical efficiency of the monitoring system at all times, and the nondestructive inspection requires high-quality manpower and expensive equipment, which is not economical.

In the conventional technology related to the constant monitoring of the safety of the structure, the internal cracks of the building structure, etc., are disclosed in Korean Patent Laid-open Publication No. 10-2000-0065831 (November 15, 2000) Discloses a technology related to a detection sensor that can be monitored.

In the prior art, an optical fiber is buried in a concrete forming a structure together with an optical connector at the end of the optical fiber, an optical fiber cable is connected to each optical connector, and a light transmitting device and a light receiving device Respectively, to constitute a detection sensor.

The sensing sensor penetrates the fiber optic cable into the body made of the same material as the structure (concrete) and embeds it in the structure. Such a conventional sensing sensor is a construction intended to be broken or deformed when internal cracks of the structure occur and cause a substantial error or obstacle to the optical transmission function.

In the structure where the sensor is embedded, the laser light is received at one end of the optical fiber cable and the laser light is received at the other end, so that the internal crack or the like of the structure can be monitored by analyzing the light reception or light amount change .

Detection sensor system using fiber optic cable can be continuously monitored only when the fiber optic cable embedded in the structure is safely installed and well preserved. If the optical fiber cable embedded by the internal cracks of the structure is cut or damaged, the optical fiber cable There is a problem that the use time is limited for a limited time because it can not be reused or restored. That is, in the prior art, if the optical fiber cable buried in the structure is damaged and the original function is lost, the safety of the structure should be monitored or diagnosed in a different manner.

In addition, due to the characteristics of the optical fiber cable in the prior art, it is easy to damage the optical fiber cable during the placement and curing of the structure (concrete), and once it is damaged, it is almost impossible to recover and it is difficult to apply it to wooden or steel frame Still remains.

As a conventional technique in which such a problem is partially improved, a laser target is configured in a portable form in Korean Patent Application No. 10-2001-0052103 (filed on August 28, 2001) "Optical Structure Safety Monitoring Device".

An improved prior art is a structure in which a linear image sensor and a beam splitter, which are laser targets, are installed on a structure in a removable and detachable manner, and a laser is outputted toward a target with a laser oscillator to measure a displacement of the structure.

However, the improved prior art is complicated in construction because the optical structure safety monitoring device is movable and has to use a plurality of lasers to measure the displacement of the structure in various places, there is a problem that the construction cost burden is increased, Therefore, real-time diagnosis such as moving the displacement sensor every measurement and fixing the reference position precisely remains.

Also, since the conventional techniques are relatively easy to approach or diagnose the safety of a structure located at a short distance, there is still a problem that it is difficult to safely diagnose a structure that is difficult to access at all times.

It is easy to operate, maintain, and diagnose safety easily, and it can be applied to safety diagnosis of all kinds of structures by remote optical photographing of the safety diagnosis of a structure which is difficult to access by using an optical telephoto lens. It is necessary to develop a technique for safely protecting the operator by securing the safety of the operator in accordance with the safety diagnosis of the difficult structure.

Therefore, the applicant of the present invention has proposed, in order to solve some of the problems of the prior art, an improved optical system using an optical lens and a telephoto lens in the safety diagnosis of civil engineering structures and buildings, which is disclosed in Korean Patent No. 10-1503693 Precision safety diagnosis method 'to solve the problem.

1 is an exploded perspective view explaining a structure of a precision safety diagnosis apparatus using an optical telescopic lens in the safety diagnosis of civil engineering structures and buildings according to an embodiment of the prior art.

Referring to FIG. 1, the improved prior art has an advantage of detecting a displacement of a building structure by measuring a difference between an angle of inclination of a reference line and an outline of a structure by applying a digital signal processing (DSP) .

However, since the improved prior art uses such an expensive digital signal processing technology, it is limited in use such that it is difficult for general workers to use and requires an experienced operator. In order to shoot a structure, There is a problem that the camera is sagged in the up / down direction due to its own weight or the like when the camera is rotated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

13 to 15, the operator installs the tripod 500 on a ground plane a certain distance from the civil engineering structure to be photographed. At this time, the worker is installed to be able to maintain the horizontal position between the tripod 500 and the ground through the level system 520 provided on the tripod 500.

The protruding portion 510 and the adjusting body 410 on the upper portion of the tripod 500 installed to be horizontal with respect to the ground can be hinged by the fixing handle 420 so that the adjusting body 410, 410 are installed so as to be adjustable in an up / down direction.

The adjusting body 410 may be fixed or detachable to the protruding portion 510 by pressing the fixing handle 420 hinged to both sides of the adjusting body 410. [

The driving unit 300 is mounted on the mounting body 430 so as to be detachably attached to the mounting body 430 through the detachable pin 433 capable of elastic restoration.

The protruding protrusion 431 protruded from the upper portion of the mounting body 430 is inserted into the guide groove 331 formed in the lower portion of the coupling plate 330. The fixing bolt 437 is screwed into the coupling hole 333 So that the coupling plate 330 is fixed to the upper portion of the mounting body 430.

The coupling plate 330 restricts the movement distance through the stopper 435 protruding from the mounting body 430.

The drive shaft 321 and the shaft insertion hole 213 protruding from the front surface of the support plate 310 are fixedly coupled to each other so that the outer surface of the roller 215 is in surface contact with the front surface of the support plate 310, Thereby allowing the body 210 to rotate leftward and rightward.

A fixing pin 233 inserted through the seating plate 230 and a lower portion of the digital camera 100 are screwed to each other and fixed to each other.

The digital camera 100 is moved in a forward direction and a backward direction along an elongated groove 235 formed in the seating plate 230 and fixed with a fixing pin 233 after the forward and backward movement is adjusted.

The insertion hole 231 of the seat plate 230 provided with the digital camera 100 and the adjustment hole 217 formed at the rear of the upper portion of the horizontal plate 210a are opposed to each other and the insertion hole 231 and the adjustment hole 217 are inserted, and then the digital camera 100 is fixed to the rotating body 210 by screwing.

The pair of fastening screws 237 are preferably screwed so that no flow occurs between the rotating body 210 and the seating plate 230.

The horizontal sensor 220 is checked to detect the horizontal state of the digital camera 100 and the deceleration motor 320 is rotated in the left or right direction through the switch unit 620 or the corresponding control command, The horizontal state is adjusted.

After the civil engineering structure confirmed through the monitor screen 110 provided at the back of the digital camera 100 with the horizontal state adjustment is photographed, the diagnostic image I is uploaded to the safety diagnosis terminal C. Here, the digital camera 100 controls, selects, shoots, and stores the focus, magnification, pixel, exposure, storage format, and the like in accordance with a control command so that the image of the subject or the specified civil engineering structure is accurately photographed And transmitted to the safety diagnosis terminal (C).

(V) programmed via the safety diagnosis terminal (C) is loaded and activated, and the diagnostic image (I) is loaded on the verification means (V) executed to determine the inclination degree of the photographed civil engineering structure (Detected).

That is, the civil engineering structure safety diagnosis apparatus 1 using the digital camera of the present invention includes a digital camera 100, a fixing unit 200, a driving unit 300, an angle adjusting unit 400, a tripod 500, 600, and a user terminal (C).

16 and 17, the safety diagnosis terminal C executes the AutoCAD program, which is one of the verification means V, and transmits the diagnostic image I ) Is loaded and displayed.

The safety diagnosis terminal C draws a center line G1 on the diagnostic image I by executing a command of a line which is a tool for drawing an arbitrary vertical line or a horizontal line by using a control command by means of a control command.

On the other hand, the safety diagnosis terminal C draws an arbitrary virtual line G2 along the center of the diagnostic image I based on the drawn center line G1.

The safety diagnosis terminal C detects the inclination angle A between the arbitrary imaginary line G2 and the center line G1 through the confirmation means V. Therefore, (C), and diagnoses, judges, or confirms the safety.

The safety diagnosis terminal C is connected to the digital camera 100 and uses a portable terminal such as a notebook computer, a personal computer, a laptop computer, or a dedicated terminal so that the degree of inclination of the civil engineering structure can be judged through the diagnostic image (I) .

The civil engineering structure safety diagnosis apparatus 1 using the digital camera thus configured uploads the diagnostic image taken by the digital camera 100 to the safety diagnosis terminal C installed with the civil structure diagnosis program. On the other hand, the safety diagnosis terminal C is relatively inexpensive and analyzes the diagnostic image I in which the civil structure is photographed using the verification means V such as AutoCAD, which is generally used, so that the displacement state or stability There is an advantage that it can be detected and diagnosed.

On the other hand, the apparatus 1 for safety analysis of a civil engineering structure using a digital camera analyzes the diagnostic image I without using expensive programs such as digital signal processing (DSP), and determines the inclined displacement state of the civil structure It is economical to use one of Auto CAD, Photoshop and Illust programs with a relatively low price in S (V), which is advantageous in that maintenance cost is low.

The apparatus for safety diagnosis of a civil engineering structure using a digital camera has a roller 215 which is in surface contact with the front surface of the support plate 310 differently from the conventional one to detect the weight of the digital camera 100, The rotation body 210 is prevented from being inclined upward (downward) by the rotation body 210 and the rotation body 210 is easily rotated when the rotation body 210 is rotated by the reduction motor 320.

18 is a flowchart for explaining a method of operating a civil engineering structure safety diagnosis apparatus using a digital camera according to an embodiment of the present invention.

Hereinafter, the digital camera 100, the horizontal control unit 600, and the safety diagnostic terminal C installed with the program are operated in an active state (S1010).

When it is determined that the corresponding control command signal for starting the safety control is inputted by the horizontal control unit 600 in step S1020, the fixing unit 200 installed in the digital camera 100 monitors the horizontal sensor 220, (S1030).

If it is determined by the horizontal control unit 600 that the fixing unit 200 is tilted to the left, the left LED L2 (hereinafter referred to as the left LED and L1 as the right LED) The driving unit 300 is driven to emit light so that the fixing unit 200 provided with the digital camera 100 is driven to rotate right (S1040).

If it is determined by the horizontal control unit 600 that the fixing unit 200 is not tilted to the left, it is determined whether the tilting of the fixing unit 200 is to the right (S1050).

If it is determined that the fixing unit 200 is tilted to the right by the horizontal control unit 600, the driving unit 300 is controlled while the right LED L1 is lit by the corresponding control signal to install the digital camera 100 And drives the fixing unit 200 to make a left turn (S1060).

Since the driving unit 300 includes the deceleration motor 320 rotating at 1 to 2 RPM, the right or left angle can be precisely controlled and adjusted.

The horizontal control unit 600 outputs a control signal to the digital camera 100 to notify that the camera is ready for photographing, if it is determined that the fixing unit forms and maintains the horizontal position through the left rotation control or the right rotation control of the deceleration motor 320 (S1080).

The digital camera 100 confirms a signal in a photographable state and selectively controls a focus, a magnification, an exposure, a pixel, and a storage format for photographing according to the corresponding control command signal. The digital camera 100 photographs a civil engineering structure, The diagnostic image I is uploaded to the safety diagnosis terminal C and stored (S1090).

In the digital image, the values of the pixels constituting the image and the format for storing the image are stored in the JPEG, TIFF, and so on.

Therefore, in the digital camera, it is very natural that many of the focus, magnification, exposure value, pixel, and format are designated in advance by a general value or method, and that any one of the values can be selected and set by the corresponding control command. A detailed description thereof will be omitted.

The safety diagnosis terminal C stores the uploaded diagnostic image I in the allocated area and selects either the AUTO CAD, the photoshop or the illust program as the verification means V It is loaded and operated in an active state.

The safety diagnosis terminal C visually displays the stored diagnostic image I by loading and displaying the stored diagnostic image I using the verification means V activated by the corresponding control command (S1100).

The safety diagnosis terminal C sets the center line G1 to the checking means V and sets the virtual line G2 to the diagnosis image I according to the corresponding control command so as to be displayed respectively at SS1110.

The safety diagnosis terminal C checks whether the center line G1 and the virtual line G2 coincide with each other by the corresponding control command in operation S1120. If it is determined that the center line G1 and the virtual line G2 do not coincide with each other, (A) formed from a state in which one end of the virtual line G1 intersects with the one end of the virtual line G2 (S1130).

It is a matter of course that the various processes described above can be variously modified, modified and improved by the development of the technology.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
