Description

{a control method of A control system that manages the construction of paving roads or bridges with concrete}

The present invention relates to a control method for a control system that manages and supervises a construction site where roads or bridges are paved with concrete.

Generally, when a road or bridge is constructed, construction is performed to pave the surface of the road or bridge with concrete.

In addition, the life cycle of concrete paved on a road or bridge surface is much shorter than that of bridge superstructures such as girders and slabs, so maintenance must be performed at an appropriate time.

Concrete pavement construction for roads or bridges is a task that has a significant impact on the lives and property of many people as well as the national operating system, so management and supervision to check whether the concrete construction on the roads is being carried out normally is essential.

In addition, since this construction involves a huge amount of manpower and budget, it is necessary to accurately identify the materials and equipment needed to complete the construction.

In the past, it was common for such management supervision and measurement of equipment, manpower, and budget to be delegated to a specific manager or person in charge of the construction site, or to be in charge at a remote location far from the construction site.

However, when such work is entrusted to an individual or a specific group, there is a problem that objectivity is low or quantitative judgment cannot be guaranteed, and objectivity cannot be guaranteed when the person in charge or the construction site changes.

In particular, road or bridge paving construction is performed by laying thin concrete over a large area, and is greatly affected by air temperature and wind. Specifically, daytime work during the summer must be sensitive to site conditions and be supervised, as there is a risk of immediate plastic shrinkage cracking. In addition, when the above-mentioned management and supervision are performed remotely, there is a problem in that weather conditions at the construction site cannot be accurately determined and time differences occur, making it difficult to accurately manage construction.

Furthermore, when the measurement of equipment, manpower, and budget is performed remotely, there is a problem of not being able to respond immediately when various variables occur at the construction site.

In particular, management and supervision of construction materials must obtain material information and transmit this information in real time to ensure quality control. However, at current construction sites, certified testing agencies measure the discharge amount of each material during a specific time using a mobile mixer and calibrate it for management. However, in reality, most mixers use foreign equipment or imported used foreign equipment, and the form of the concrete production management panel differs depending on the manufacturer and model, making unified management and supervision impossible.

The present invention aims to solve the problem of providing a control system that can film, store, and supervise road or bridge pavement construction sites in real time.

Below, an embodiment in which the control system of the present invention grasps the construction information will be described.

Figure 3 shows one embodiment of the deck finisher of the present invention.

The control system of the present invention may include a camera unit capable of photographing the road 100 or the construction site.

The camera unit may be installed on the deck finisher 400 disposed at the construction site.

The deck finisher 400 is an essential component at a construction site where concrete (C) is paved on the road 100, and is always placed at the construction site. In addition, since the deck finisher is configured to be placed at the upper part of the construction site, when the camera unit is installed in the deck finisher, it is possible to prevent creating a separate space to place the camera unit at the construction site, and the camera unit It can also block the movement of other equipment or workers located at the construction site. Moreover, by being fixed to the deck finisher 400, the camera unit can be fundamentally prevented from interfering with the construction site.

Specifically, the deck finisher 400 moves back and forth between a support frame 410 disposed in the width direction of the road at the top of the road and a lower part of the support frame 410 to remove the concrete laid on the road. It may include a pressurizing flattening device 420.

The camera unit may include a deck camera (510, 520) that is coupled to the support frame and photographs the concrete laid on the road.

The deck cameras 510 and 520 may be provided to directly photograph the concrete laid on the road or to film a construction site where the concrete is laid. The deck cameras (510, 520) can photograph the overall progress of construction, such as the laying state of the concrete, the leveling state of the concrete, and the curing state of the concrete.

The deck cameras 510 and 520 may be placed on the leveling device 420, but are placed on the support frame 410 so that they can photograph the construction site from a higher place than the leveling device 420.

In addition, the deck cameras 510 and 520 are arranged on the support frame 410, so that the installation position is fixed and the area to be photographed can be photographed for a long time. As a result, the deck camera can also detect changes in the shooting area in real time.

The deck cameras 510 and 520 may store the construction information in real time while photographing the construction site, and may transmit the captured images to the control room 700 or the management vehicle 200.

For this purpose, the control system of the present invention may further include deck transmission equipment 430 that receives images captured by the deck cameras 510 and 520 and transmits them to the control room 700 or the management vehicle 200. The deck transmission equipment 430 may be equipped with any configuration, such as VPN equipment, as long as it can connect to a common network and transmit the video. Accordingly, the captured image can be transmitted to the control room 700 or the management vehicle 200 without a separate transmission device in the deck cameras 510 and 520 or the deck finisher 400.

Meanwhile, the deck cameras 510 and 520 may be equipped to operate with a power or voltage different from the power or voltage at which the deck finisher operates. To this end, the control system of the present invention may be equipped to supply customized power to the deck camera by arranging a deck generator 440 provided separately from the deck finisher. Accordingly, even if the deck finisher is not in operation, the deck camera can capture and record the construction site for a long time. The deck generator 440 may be placed and fixed on the support frame 410.

Meanwhile, the deck cameras 510 and 520 are fixed to the support frame 410 and can immediately capture the surface condition of the concrete distributed and leveled by the leveling device 420. Therefore, the control room 700 and the management vehicle 200 or the portable management equipment 220 can immediately confirm and inspect the construction status of the concrete (C) paved on the road. As a result, many people can check the construction status, thereby maximizing the completeness of the concrete paving construction.

The control room 700 and the management vehicle 200 may store the captured images. As a result, deficiencies in the construction can be easily checked and immediately corrected even after the fact through analysis of the captured images.

The deck cameras 510 and 520 may be arranged to be spaced apart in plural numbers on the support frame 410. As a result, the deck cameras 510 and 520 can capture, transmit and record a wider construction site.

The deck cameras 510 and 520 are provided in plural numbers and arranged to be spaced apart from each other, so that even if the paved road is a wide road with two or more lanes, the entire construction area A2 can be photographed simultaneously.

Meanwhile, even if the deck cameras 510 and 520 are provided in plural numbers, they can be provided to photograph the same construction area (A2).

The deck cameras 510 and 520 are fixed to the support frame 410 and are fixed to the first camera 510, which photographs the concrete pressed by the leveling device 420, and are spaced apart from the first camera. It may include a second camera 520 that photographs the concrete pressed by the leveling device. The first camera 510 and the second camera 520 may be equipped to photograph the same area.

The construction area A2 may be defined as an area corresponding to a portion of the concrete surface paved on the road through the leveling device 420. The deck cameras 510 and 520 can capture three-dimensional image information about the construction area A2 by photographing the construction area A2 from different positions. As a result, managers located in the control room 700, etc. can identify and inspect with realism whether the construction area A2 has been properly constructed.

In order to accurately photograph the shape of the construction area, the deck cameras 510 and 520 may include a video camera that determines the shape of the concrete laid on the road. The video camera may be provided as an IP camera or the like.

Meanwhile, the deck cameras 510 and 520 may include a video camera that determines the shape of the concrete laid on the road and a thermal image camera that determines the temperature of the concrete laid on the road.

The deck cameras 510 and 520 may be provided with only the video camera or only the thermal imaging camera. When provided in plural, some of the deck cameras 510 and 520 may be provided with video cameras and others may be provided with thermal imaging cameras.

In other words, the deck cameras 510 and 520 may be at least partially applied as thermal imaging cameras for the purpose of quality (temperature) control of the concrete being laid. However, a video camera may also be provided to capture an actual visually recognizable image of the road.

When the deck cameras 510 and 520 include a thermal imaging camera, the deck camera can determine the state of the concrete being laid and the curing or leveling state of the paved concrete.

The control room 700, etc. contains the temperature of the concrete discharged from the mobile mixer 200 when it is in a normal state, the temperature of the concrete when the leveling operation is normally completed, and the temperature of the concrete when it is normally hardened over time. All temperatures may be stored in a table, etc.

The operator or calculation server 711, which receives the temperature information of the concrete through the deck cameras 510 and 520 in the control room 700, etc., compares and analyzes the temperature of the concrete according to the construction situation and the temperature of the concrete in a normal state. Thus, it is possible to accurately and numerically check whether the construction is being performed normally for each process. Through this, the control room 700 can deliver accurate instruction information to the construction site.

Hereinafter, the deck cameras 510 and 520 will be described assuming that all of the deck cameras 510 and 520 are equipped with thermal imaging cameras. However, this is only an example and does not exclude an embodiment in which only some of the deck cameras 510 and 520 are equipped with thermal imaging cameras and the rest are equipped with video cameras.

In addition, the description is based on the fact that two deck cameras (510, 520) are provided, but this is only an example and does not exclude that three or more deck cameras (510, 520) are provided.

The deck cameras 510 and 520 are fixed to the support frame 410 and are fixed to the first camera 510, which photographs the concrete pressed by the leveling device 420, and are spaced apart from the first camera. It may include a second camera 520 that photographs the concrete pressed by the leveling device.

The first camera 510 and the second camera 520 may be equipped to photograph the same area.

However, the temperature ranges that the first camera 510 and the second camera 520 can capture may be set differently. The temperature range that the first camera 510 can detect may be set higher than the temperature range that the second camera 520 can detect. For example, the first camera 510 detects whether the concrete is placed, paved, and flattened, and the second camera 520 detects whether the leveling is completed and the curing or hardening process is completed. You can detect whether it is normal.

As a result, the control system of the present invention includes a camera unit coupled to the deck finisher 400, a self-generator that supplies power to the camera unit, and a self-transmitting device that transmits the image captured by the camera unit to the outside of the construction site. Including, the construction site (A2) can be effectively identified and managed and supervised in real time or after the fact from a remote location.

Figure 4 shows an image actually captured when the deck camera is composed of a plurality of cameras.

The camera unit of the control system of the present invention may include a plurality of video cameras and a plurality of thermal imaging cameras mounted on the deck finisher 400.

Referring to Figures 4(a) and 4(b), the control system of the present invention captures the construction area (A2) with a plurality of video cameras and provides visual information about the construction status of the construction area (A2) from various directions. It can be obtained.

In addition, referring to Figures 4(c) and 4(d), the control system of the present invention photographs the construction area (A2) with a plurality of thermal imaging cameras to provide information on the construction status of the construction area (A2) from various directions. Thermal information can be obtained.

Accordingly, the control system of the present invention can generate at least part of the construction information by combining the visual information and the thermal information. Additionally, the construction information can be stored or analyzed to generate accurate instruction information.

Figure 5 shows one embodiment of the mobile mixer of the present invention.

The control system of the present invention may include a camera unit capable of photographing the road 100 or the construction site.

The camera unit may be installed on the mobile mixer 300 located at the construction site.

The mobile mixer 300 is an essential component at a construction site where concrete (C) is paved on the road 100, and is always placed at the construction site.

In addition, since the mobile mixer 300 is configured to be placed and move along the longitudinal direction of the construction site, when the camera unit is installed in the mobile mixer 300, the concrete is laid along the longitudinal direction of the road and The packaging condition can be continuously monitored.

As a result, the control system of the present invention can prevent the creation of a separate space to place the camera unit at the construction site, and can also prevent the camera unit from interfering with the movement of other equipment or workers located at the construction site. there is. Moreover, by fixing the camera unit to the mobile mixer 300, it is possible to fundamentally prevent the camera unit from interfering with the construction site.

Specifically, the mobile mixer 300 includes a mobile vehicle 310 that transports the concrete, and a discharge unit 320 that is coupled to or extends from the mobile vehicle 310 to discharge the concrete onto the road 100. It can be included.

The control system of the present invention may be equipped with a camera unit coupled to the mobile mixer 300 to photograph the concrete discharged from the discharge unit 320. In other words, the camera unit may include a mixer camera 530 that is coupled to the mobile vehicle 310 and photographs the concrete discharged from the discharge unit 320 or laid on the road.

The mixer camera 530 is disposed above the discharge unit 320 and can capture the concrete being laid on the road 100 from the discharge unit 320 in real time.

The mixer camera 530 may store the construction information in real time while photographing the construction site where the concrete is laid, and may transmit the captured image to the control room 700 or the management vehicle 200.

For this purpose, the control system of the present invention may further include mobile transmission equipment 330 that receives the image captured by the mixer camera 530 and transmits it to the control room 700 or the management vehicle 200. The mobile transmission device 330 may be equipped with any configuration, such as a VPN device, as long as it can connect to a common network and transmit the video. Accordingly, the captured image can be transmitted to the control room 700 or the management vehicle 200 without a separate transmission device in the mixer camera 530 or the mobile mixer 300.

Meanwhile, the mixer camera 530 may be configured to operate at a power or voltage different from the power or voltage at which the mobile mixer 300 operates. To this end, the control system of the present invention may be equipped to supply customized power to the mixer camera 530 by arranging a mobile generator 430 provided separately from the mobile mixer 300.

Custom power could be 220v for example.

Meanwhile, the mixer camera 530 is fixed to the rear of the mobile vehicle 310 and can immediately capture the state of concrete being laid from the discharge unit 320. Therefore, the control room 700, the management vehicle 200, or the portable management equipment 220 can immediately confirm and inspect the condition of the concrete (C) laid on the road.

As a result, many people can check the construction status and accurately check the condition of the concrete being laid.

The control room 700 and the management vehicle 200 may store the captured images. As a result, it is possible to check whether the concrete laid on the road is in normal condition and of the correct amount through analysis of the captured image even after the fact.

The mixer camera 530 may be installed on a fixed plate that does not rotate or move on the back of the mobile vehicle 320.

Additionally, the mixer cameras 530 may be provided in plural numbers and arranged to be spaced apart from each other.

For example, the mixer camera 530 may include a video camera to photograph the amount of concrete being laid from the discharge unit 320 and the form of concrete starting to be laid on the road.

In addition, the mixer camera 530, including a thermal imaging camera, can photograph the state of concrete being laid from the discharge unit 320 and the state of concrete starting to be laid on the road.

The control room 700 may have normal concrete conditions stored in advance. For example, in normal cases, the shape, temperature, and discharge of concrete may be stored.

Accordingly, the control room 700 can determine whether the concrete discharged from the mobile mixer 300 is in a normal state by comparing and analyzing the stored information and the image information captured by the mixer camera 530.

Additionally, the control room 700 can calculate the amount of concrete discharged from the mobile mixer 300 and quantitatively measure the amount of concrete input into construction.

Figure 9 shows an embodiment of additionally understanding the construction information.

The control system of the present invention may further include a sensor unit 800 disposed on the road 100 and capable of measuring road conditions.

The sensor unit 800 may be placed on the road while being spaced apart from both the mobile mixer 300 and the deck finisher 400. The sensor unit 800 may be disposed on the road 100 to detect the road condition 100 before the concrete is paved and the road condition 100 on which the concrete is at least partially paved. .

Specifically, the sensor unit 800 may be provided to measure the road not only in the longitudinal direction of the road and the width direction of the road, but also in the height direction of the road.

The sensor unit 800 can measure the road 100 in three dimensions at the deployed location by measuring all three directions on the deployed road 100.

The sensor unit 800 may include a main body 810 that measures the road 100, and a support 820 that supports the main body 810 by spacing the main body 810 at a certain height from the road. there is.

The main body 810 may include a measuring unit that measures the road in three dimensions, a storage unit that temporarily stores the survey information measured by the measuring unit, and a communication unit that can transmit the survey information on a public network. You can.

As a result, the sensor unit 800 can transmit the measurement information by connecting to the control room 700, the management vehicle 200, or portable equipment, and the control system of the present invention can accurately determine the three-dimensional condition of the road on which concrete is laid. You can.

The control system of the present invention detects the condition of the road surface in three dimensions through the measurement information measured by the sensor unit 800 and determines one or more of the amount of materials including concrete required to pave the road, construction equipment, and construction date. can do.

Figure 10 shows how the sensor unit is utilized.

The sensor unit 800 measures the state of the road 100 in 3D based on the deployed location. Accordingly, the more the sensor unit 800 measures the road 100 while changing its arrangement position, the more accurately the measurement information of the road 100 can be obtained.

As a result, the control system of the present invention can achieve the effect of 3D scanning the road 100 by arranging the sensor unit 800 throughout the road 100.

The sensor unit 800 may be placed on a concrete surface 110 on which paving has already been completed, or on the surface 120 of a road that has not yet been paved.

When the sensor unit 800 is disposed on the concrete surface 100, a detailed 3D map of the surface of the concrete paved on the road 100 can be obtained. As a result, the control system of the present invention can obtain specific information about the amount of material such as concrete paved on the road 100 and the shape of the surface paved with concrete through the 3D information.

Additionally, as the sensor unit 800 is disposed on the surface 120 of the road, a specific 3D map of the surface 120 of the road 100 can be obtained. As a result, the control system of the present invention can obtain specific information about the amount of materials such as concrete required to pave the road 100, the construction date, and construction equipment that can be deployed.

Meanwhile, more of the sensor units 800 may be placed on the unconstructed road 120 than on the constructed road 110.

For example, on the concrete-paved road 110, measurement information can be obtained by sequentially placing positions 1, 2, and 3, and on the concrete-paved road 120, positions 5 to 5 are located. It is placed sequentially in 10 places and survey information can be obtained.

As a result, the control system of the present invention can more reliably calculate the amount of materials such as concrete required to pave the road 100, the construction date, and the construction equipment that can be deployed.

In addition, the control system of the present invention can obtain 3D information of the road by matching the measurement information in the sensor unit 800 itself or in the control room 700 that has received the measurement information acquired by the sensor unit 800. .

The control system of the present invention can store the 3D information acquired by the sensor unit 800 in the calculation server 711 as a database, and the database can be utilized in various ways in various portable devices or the situation room 720. there is.

Figure 11 shows a state in which the sensor unit measures an actual road.

Referring to Figure 11(a), the road 100 may be provided in a state before concrete is yet paved.

Referring to FIG. 11(b), the sensor unit 800 is placed at a specific location on the road 100, and 3D surveys the road 100 based on the specific location and obtains measurement information. .

The survey information may include an image in which the state of the road 100 is reinterpreted in 3D based on the disposed sensor unit 800.

The sensor unit 800 or the control room 700 can match the survey information to obtain 3D information on the road that is the same as the actual road 100 condition and output specific construction information.

The sensor unit 800 may be equipped with a LiDAR sensor to 3D scan the road 100. Additionally, the control system can realize actual road conditions in 3D by matching point cloud data measured by the LiDAR sensor.

Specifically, in order to measure and scan the road in 3D, point cloud data can be collected by measuring the road 100 at a specific point through the sensor unit 800.

The control system can obtain the three-dimensional shape of the road 100 by performing a matching process to convert data acquired from many measuring points into one data with a unified coordinate system.

In other words, the sensor unit 800 acquires scan data from a point measured at one point of the road 100, that is, one measuring point, and the data can be stored as point cloud data with a local coordinate system.

However, since it is impossible to generate all information about the road 100 only with data acquired from one measuring point, the sensor unit 800 is measured at several measuring points of the road 100 to obtain a plurality of point cloud data, and the present invention The control system performs a matching step to convert this into a single point cloud data with a unified coordinate system through data collection and processing devices such as the server room 710.

As a result, the control system of the present invention converts all data measured by the sensor unit 800 into 3D space through a matching process of arranging point cloud data acquired from multiple measuring points centered on one or multiple objects into a common coordinate system. It can be reconstructed.

To this end, the sensor unit 800 may be equipped with a lidar sensor corresponding to a 3D laser scanner. Point cloud data is collected through this device, and 3D modeling is created through a matching process based on the collected point cloud data. The LIDAR currently has a variety of common and complementary technologies that can map the surroundings and measure object speed.

When the sensor unit 800 is equipped with a LiDAR sensor, it can detect objects from several meters to more than 200 meters away, and due to its ability to aim laser light, it uses a short wavelength of 905 to 1550 nm to detect objects at a distance of 0.1°. It is possible to secure spatial resolution that can be divided into units. Accordingly, the sensor unit 800 can depict the characteristics of objects in 3D as a scene without back-end processing.

The sensor unit 800 may use either a time-of-flight (TOF) method or a phase-shift method depending on the laser signal modulation method. The TOF method makes it possible to measure distance by measuring the time when a laser emits a pulse signal and reflected pulse signals from objects within the measurement range arrive at the receiver. The phase-shift method calculates time and distance by emitting a laser beam that is continuously modulated with a specific frequency and measuring the amount of phase change in the signal reflected back from objects within the measurement range.

The laser light source used in the sensor unit 800 may have a specific wavelength in the wavelength range from 250 nm to 11 μm or may be a laser light source whose wavelength can be varied.

Additionally, the sensor unit 800 can recently use a semiconductor laser diode that is small and low-power.

The sensor unit 800 may be provided as either a fixed lidar or a mechanical lidar that rotates 360°. The solid-state lidar has an excellent horizontal field of view (FOV), but the mechanical lidar system that rotates 360° has the widest field of view among all ADAS (Advanced Driver Assistance Systems) technologies. Additionally, LIDAR is known to have an advantage over radar in angular resolution (both viewing angle and elevation).

If the sensor unit 800 is equipped with the fixed LiDAR, it is cheaper because there are no rotating mechanical components and the FOV is reduced, and by fusing survey data measured at multiple measurement points, a FOV comparable to that of the mechanical LiDAR is created. You can lose.

Therefore, the control system of the present invention may be equipped with the sensor unit 800 as a fixed lidar. As a result, the road 100 can be measured without difficulty even in an environment where the construction site is not large enough to use a mechanical LIDAR and a vehicle equipped with a mechanical LIDAR cannot pass.

Meanwhile, the control room 700 can receive measurement data from the sensor unit 800 and match them. Specifically, registration of 3D point cloud data can be done using either coarse registration methods that utilize the characteristics of points, lines, and surfaces, or fine registration methods that increase registration precision.

When the control room 700 of the present invention uses a feature-based rough matching method, points, lines, and surfaces are selected from objects with properties that do not change over a certain period of time, such as the edges and outlines of buildings on scan data, roads, roofs, and road signs. Matching between scan data is performed using criteria such as: The application methods of these point-based methods, line-based methods, and surface-based methods vary depending on the subject of the scan.

The control room 700 of the present invention can also match point cloud data using a fine matching method.

The control room 700 of the present invention can use any one of ICP, Random Sample Consensus Methods (RANSAC), Normal Distribution Transform Methods (NDT), and Methods with Auxiliary Data. .

Meanwhile, the control system of the present invention can also be used in BIM technology through this 3D scanning method.

Building Information Modeling (BIM) is a technology that digitally creates one or more accurate virtual models of a building, supporting design step by step and enabling more effective analysis and control than manual processes.

Therefore, the control system of the present invention can be equally applied to the BIM technology in addition to managing and supervising the concrete pavement construction of the road 100.

Figure 12 shows an example of scanning a road before and after construction using the sensor unit.

The drawing on the left shows the road before the concrete is paved, and the drawing on the right shows the road after the concrete is paved.

The control system of the present invention can measure roads by placing them in various locations before concrete is paved through the sensor unit 800. The control system of the present invention can match road survey information measured by the sensor unit 800 when it is provided as point cloud data.

When specific 3D shape information is obtained through a matching process, the 3D shape can be adjusted to match the actual length.

To this end, the sensor unit 800 or the control system can measure the exact length of the actual road 100. As a result, it is possible to obtain realistic 3D road scan information by providing an accurate length standard to the 3D shape and store it as a database in the calculation server 711, etc.

Additionally, the control system of the present invention can scan the paved road 100 in the same manner through the sensor unit 800.

The paved road 100 may correspond to a road under construction or a road whose construction has been completed.

As a result, the control system of the present invention can check the concrete pavement status of a road on which construction has been at least partially completed in 3D. Furthermore, by comparing a road where construction has not been completed with a road where construction has been completed, the amount of material required can be calculated by comprehensively calculating the area of concrete to be paved and the thickness of the concrete to be paved.

As a result, when measuring the construction site through the sensor unit 800, the control system of the present invention can measure the condition of the road 100 without difficulty even at night. In addition, the control system of the present invention can accurately measure the condition of the road 100 even without a deck finisher or mobile mixer before actual construction begins.

In addition, the control system of the present invention provides data on the road condition before construction measured by the sensor unit 800, the road condition after completion of construction measured by the sensor unit 800, or the road condition after partial completion of construction through a 3D map. You can compare above. As a result, the control system of the present invention can calculate whether the construction is structurally progressing normally, whether the concrete is curing or hardening normally, and the specific amount of material required for the construction, all based on data.

Additionally, the control system of the present invention may utilize all of the above-described camera unit and the sensor unit 800, or may utilize only some of them.

Figure 13 shows an embodiment of the control method of the control system of the present invention.

The control system of the present invention can perform a detection step (S1) of measuring the road 100 before construction using the sensor unit 800.

The sensing step (S1) may include 3D sensing or measuring the road 100. The detection step (S1) may be performed repeatedly by changing the location on the road 100. For example, the detection step (S1) may be performed repeatedly while changing at least three of the longitudinal direction of the road 100 and the width direction of the road 100.

When the detection step (S1) is performed, the control system of the present invention may include a data construction step (S2) of constructing a database necessary to convert the survey information measured by the sensor unit 800 into a 3D map. .

The data construction step (S2) is a process of matching the survey information and may correspond to a pre-processing step for implementing the 3D map.

When the data construction step (S2) is completed, the control system of the present invention can perform a scanning step (S3) to implement the road 100 as a 3D map on the data.

Through this process, the control system of the present invention can accurately recognize the condition of the road 100 based on data. That is, the control system of the present invention can obtain specific information about the actual width, actual length, and actual shape of the road 100 as data.

As a result, the control system of the present invention can perform a calculation step (S7) to specifically calculate the equipment, amount of materials, and time needed to actually construct the road 100 and accurately establish a construction plan.

When the detection step (S1), construction step (S2), and scan step (S3) performed before constructing the road 100 are completed, the calculation step (S7) can be performed normally.

The calculation step (S7) may be performed in the control room 700 or in a portable device, and may be one of the area of the concrete to be laid on the road, the height of the concrete, and the amount of concrete material required for paving the road. Instruction information including the above can be calculated.

The control system of the present invention can perform construction of paving the road 100 with concrete through the instruction information performed in the calculation step (S7).

In any case, whether in the process of performing the construction or in a state in which the construction is completed, the control system of the present invention performs a re-detection step (S4) of measuring the state of the road on which the concrete is at least partially paved with the sensor unit 800. can do.

The re-sensing step (S4) may include 3D sensing or measuring the road 100. The re-detection step (S4) may be performed repeatedly by changing the location on the road 100. For example, the re-detection step (S4) may be performed repeatedly while changing at least three of the longitudinal direction of the road 100 and the width direction of the road 100.

When the re-detection step (S4) is performed, the control system of the present invention will include a data reconstruction step (S5) of constructing a database necessary to convert the survey information measured by the sensor unit 800 into a 3D map. You can.

The data reconstruction step (S5) is a process of matching the survey information and may correspond to a preprocessing step for implementing the 3D map.

When the reconstruction step (S5) is completed, the control system of the present invention implements the road 100 as a 3D map on the data and performs a comparison step (S6) to compare it with the previous 3D map.

When the comparison step (S6) is performed, the control system of the present invention specifically calculates the equipment, amount of material, and time required to additionally construct the road 100, and accurately establishes a construction plan (S7). ) can be performed.

The calculation step (S7) performed after the scan step (S3) and the re-detection step (S4) includes at least one of the calculated area of the concrete, the height of the concrete, and the amount of material of the concrete, and the pavement on the road. It may further include comparing at least one of the area, height, and material amount of the concrete to determine the progress of the construction.

In addition, the calculation step (S7) may further include calculating at least one of the area, height, and material amount of the concrete required to complete paving of the road.

As a result, the instruction information to be calculated may vary depending on the time when the calculation step (S7) is performed and the state in which construction is progressing, and the control system of the present invention transmits instruction information that varies in real time to the construction site to Construction can be managed, supervised, and instructed in real time.

Although not shown, the control system of the present invention may further include a final detection step (S8) in which the state of the road on which construction has been completed is measured by the sensor unit.

When the final 3D map of the road 100 is acquired as data through the final detection step (S8), the control system of the present invention uses the final 3D map in the calculation step (S7) and the instructions designed through the calculation step before construction. By comparing the information, it is possible to determine whether the construction was completed normally.

As a result, the control system of the present invention can compare actual instruction information with the road pavement condition on site, accurately determine the deficiencies and contents, and perform customized inspection and additional repair work.

In addition, the control system of the present invention collects all images or 3D data about the construction information before construction measured by one or more of the camera unit 500 and the sensor unit 800, construction information during the construction process, and construction information after construction completion. All can be saved and stored, and can be used as a database to effectively carry out the next construction.

Figure 14 shows an embodiment of paving, maintaining and repairing the road through the control method.

Figure 14(a) shows the calculated and designed instruction information for normally paving the road in the calculation step (S7) performed before the construction.

The instruction information may include a target state for completely paving the road 101 before construction. The target state is the material and thickness of the deteriorated member 102, which is primarily paved on the road 101 or slab before construction, and the material and thickness of the concrete 103, which is secondarily paved on top of the deteriorated member 102. It can be included.

Figure 14(b) shows the 3D survey state of the road 100 actually measured in the re-detection step (s4) or the final detection step (s8).

As a result of measuring the road 100 in 3D, it can be seen that the pavement is insufficient in a specific area. For example, the control system of the present invention measures the surface of the road 100 with the sensor unit 800, detects areas where the surface of a specific area (A1) is different from that of a low height, and performs construction in the specific area. This defect can be judged.

In addition, the control system of the present invention can additionally accurately calculate the amount of one or more materials among concrete and deteriorated members required to repair the specific area (A1).

The control system of the present invention determines how low the height is in the specific area in the control room 700 through the calculation step (S7), determines whether the deterioration member 102 is insufficient, and if the deterioration member is insufficient, determines the actual shortage amount, If there is a shortage of concrete (103), one or more of the actual shortage amounts can be calculated.

In other words, rather than simply calculating the amount of concrete by simply calculating the collapsed or unconstructed volume in the road 100, the control system of the present invention calculates the material layer that must be placed according to the actual thickness of the road 100. By calculating the arrangement and thickness of and the type and amount of each material to be constructed in the caved or unconstructed volume of the road 100, the materials actually needed and the construction steps to be performed sequentially can be accurately identified.

As a result, the specific area (A1) can be repaired using the optimal method and construction without wasting materials, and the integrity of the specific area (A1) can be guaranteed so that it can be constructed in almost the same condition as other areas. .
