Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an unmanned construction system and method for prefabricated buildings. Background Technology

[0002] With the development of modern industrial technology, houses can be manufactured in batches, much like machine production. All that's needed is to transport the prefabricated house components to the construction site and assemble them.

[0003] Prefabricated construction began to attract attention in the early 20th century and was finally realized in the 1960s. Britain, France, and the Soviet Union were among the first to experiment with it. Due to its rapid construction speed and low production costs, prefabricated buildings quickly spread throughout the world.

[0004] Early prefabricated buildings had rather rigid and uniform appearances. Later, improvements were made in design, increasing flexibility and diversity, enabling mass production and a wide variety of styles. In the United States, there is a type of mobile home, a more advanced form of prefabricated building. Each unit is like a large trailer; it is towed to the site by a special vehicle, then lifted by a crane onto floor blocks and connected to pre-installed plumbing, power, and telephone systems, making it ready for use. The mobile homes include heating, bathrooms, kitchens, dining rooms, and bedrooms. Mobile homes can stand alone or be interconnected.

[0005] In existing technologies, the construction of prefabricated buildings requires on-site workers to perform engineering surveys and install prefabricated components. While these tasks effectively complete the construction of prefabricated buildings, they require significant manpower and resources. Furthermore, the on-site work exposes workers to wind, rain, and intense sunlight, posing safety risks. Additionally, the varying skill levels of the workers can impact the construction efficiency of prefabricated buildings. Summary of the Invention

[0006] The main objective of this invention is to provide an unmanned construction system and method for prefabricated buildings, aiming to solve the technical problems existing in related technologies, such as the fact that construction workers need to work on-site during construction, which makes their personal safety affected by wind, rain or scorching sun, and the fact that the varying quality of construction workers also affects the construction efficiency of prefabricated buildings.

[0007] To achieve the above objectives, in a first aspect, the present invention proposes an unmanned construction system for prefabricated buildings, which is applied to the unmanned construction of the prefabricated building at the construction site, wherein the prefabricated building is assembled from multiple prefabricated components.

[0026] The control subsystem can control the walking component to walk on the construction site according to the path planned by the engineering drone, so as to transport the prefabricated component mounted on the second mounting mechanism to the target installation position.

[0027] Optionally, the prefabricated component is provided with a plurality of second connectors;

[0028] The second mounting mechanism includes:

[0029] A second connecting frame, the second connecting frame being mounted on the mounting surface; and...

[0031] Optionally, the prefabricated component is further provided with a plurality of spaced-apart third connectors;

[0032] The installation mechanism includes:

[0033] At least two flip-up members are circumferentially spaced and mounted on the sides of the second connecting frame, and the flip-up members are detachably connected to the third connecting member; and,

[0034] At least two mounting pieces, the number of which is the same as the number of the flipping pieces, are arranged one-to-one on the side of the second connecting piece;

[0035] The plurality of flipping components can cooperate with each other to remove the prefabricated component from the second mounting component and flip it to the target installation position, and the plurality of mounting components can cooperate with each other to install the prefabricated component flipped to the target installation position.

[0036] Based on the same technical concept, in a second aspect, the present invention also proposes an unmanned construction method for prefabricated buildings, which applies the unmanned construction system for prefabricated buildings described in the first aspect.

[0037] The unmanned construction method for prefabricated buildings includes the following steps:

[0038] The construction site is surveyed and scanned using the unmanned aerial vehicle (UAV) subsystem to form a first database of the construction site in the control subsystem; wherein, the first database includes spatial coordinate data information of the construction site;

[0039] Based on the first database, the control subsystem controls the engineering drone to measure and lay out the preset construction outline of the prefabricated building at the construction site; wherein, the preset construction outline includes a preset installation path, and multiple spaced target installation positions are formed on the preset installation path;

[0040] The control subsystem is used to control the prefabricated component assembly subsystem to transport the prefabricated component to one of the target installation locations and install it;

[0041] According to the preset construction path, the steps of using the control subsystem to control the prefabricated component assembly subsystem to transport the prefabricated component to one of the target installation locations and install it are repeated until the installation of the prefabricated building is completed.

[0042] Optionally, the step of controlling the engineering drone to measure and lay out the preset construction outline of the prefabricated building at the construction site using the control subsystem based on the first database includes:

[0044] All the prefabricated components in the BIM model database are coded to form a preset layout path;

[0045] According to the preset layout path, the control subsystem controls the engineering drone to measure and lay out the preset construction outline of the prefabricated building at the construction site.

[0046] Optionally, before the step of using the UAV subsystem to perform surveying and scanning of the construction site to form a first database of the construction site in the control subsystem, the method further includes:

[0047] The construction site was mapped using the engineering drone to obtain the dispatch location;

[0048] Control the scheduling drone to fly to the scheduling location to establish a communication link.

[0049] This invention's technical solution involves setting up a control subsystem, a drone subsystem, and a prefabricated component assembly subsystem. The control subsystem is positioned outside the construction site, while the drone subsystem is deployed above the site. The drone system's dispatching mechanism executes dispatch commands over the construction site, and at least one engineering drone flies over the site to execute engineering instructions. Under these conditions, a transporter within the prefabricated component assembly subsystem transports the prefabricated components to the target installation location, and an installation mechanism installs the components there. This allows the invention to facilitate prefabricated building installation operations through the coordinated use of the control subsystem, drone subsystem, and prefabricated component assembly subsystem. Because the engineering drone flies over the construction site, it can perform tasks on-site. The system enables the transmission of engineering commands such as surveying, setting out, monitoring, and data transfer, eliminating the need for on-site construction workers. Furthermore, by utilizing a prefabricated component assembly subsystem to assemble prefabricated components to their target installation positions, and then using an installation mechanism to install them, the invention allows for the simultaneous installation of prefabricated components using a control subsystem and a drone subsystem, eliminating the need for on-site construction workers. This solves the technical problems inherent in related technologies where on-site construction workers are exposed to wind, rain, or intense sunlight, posing safety risks. Additionally, the varying skill levels of construction workers can negatively impact the efficiency of prefabricated building construction. Attached Figure Description

[0067] The inventive concept of the present invention will be further explained below with reference to some specific embodiments.

[0068] This invention proposes an unmanned construction system and construction method for prefabricated buildings.

[0069] like Figures 1 to 9 As shown, an embodiment of the unmanned construction system and construction method for prefabricated buildings of the present invention is presented.

[0070] This type of unmanned construction system for prefabricated buildings is used for unmanned construction on the construction site of prefabricated buildings. The prefabricated buildings are assembled from multiple prefabricated components.

[0071] The unmanned construction system for prefabricated buildings includes:

[0072] Control subsystem 200 is located outside the construction site;

[0073] A drone subsystem 300 is deployed over the construction site. The drone subsystem 300 includes a dispatch drone 310 and at least one engineering drone 320. The dispatch drone 310 integrates a communication link module 330 that simultaneously communicates with the control subsystem 200 and the at least one engineering drone 320. The engineering drone 320 can fly over the construction site to execute engineering commands sent by the control subsystem 200 through the communication link module.

[0074] The prefabricated component 100 assembly subsystem is connected to the communication link module. The prefabricated component 100 assembly subsystem includes at least one transporter 410 and at least one installation mechanism 420. The transporter 410 is loaded with prefabricated components 100, and at least one installation mechanism 420 is installed on each transporter 410. The installation mechanism 420 is used to install the prefabricated component 100 to the target installation position.

[0075] The control subsystem 200 can control the engineering drone 320 to plan and navigate the transport vehicle 410 at the construction site, and enable the transport vehicle 410 to transport the prefabricated component 100 to the target installation location.

[0076] It is important to note that, for the convenience of technicians, the control subsystem 200 needs to include a flight control module for controlling the UAV subsystem 300, an assembly control module for controlling the prefabricated component 100 assembly subsystem, a data processing module for data processing, and an operation module for executing BIM information input by construction personnel. All modules are communicatively connected. It is worth noting that this embodiment only sets up the relevant functional modules and does not improve or design the specific working principles of each functional module; therefore, the specific usage methods of each functional module will not be described in detail here.

[0077] To facilitate a better understanding of this invention by construction personnel, the unmanned construction system for prefabricated buildings exemplified by this invention will be described and explained in detail in this embodiment:

[0078] To more clearly and explicitly demonstrate the unmanned construction function of prefabricated buildings of the present invention, when using the unmanned prefabricated construction system of the present invention for prefabricated construction, a control subsystem 200 can be first set up in an area outside the construction site. After the control subsystem 200 is set up, the control subsystem 200 is used to control the engineering drone 320 to fly to the construction site and perform surveying and scanning of the construction site to obtain the spatial coordinate information of the construction site. After obtaining the spatial coordinate information of the construction site, and combining it with the construction data of the prefabricated building, at least one scheduling position is determined in the airspace above the construction site. After the scheduling position is determined, the control subsystem 200 is used to control the scheduling drone 310 to fly to the scheduling position to complete the establishment of the communication link system. After the communication link is established, the control subsystem 200 is used to control the prefabricated component 100 assembly subsystem to move to the construction site to complete the preparation before construction.

[0079] It needs to be further clarified and explained that, in this embodiment, when determining the scheduling location, the scheduling operation of the entire construction process at the construction site should first be considered. It is clear that throughout the entire construction process, the scheduling drone 310 can always provide scheduling instructions for all equipment at the construction site, and these instructions will not be interfered with by any external structures. Simultaneously, when the prefabricated component 100 assembly subsystem moves to the construction site, the control subsystem 200 can directly control the movement of the prefabricated component 100 assembly subsystem to the construction site, or the control system can control multiple engineering drones 320 to hoist and deploy the prefabricated component 100 assembly subsystem to the construction site.

[0080] To enable construction workers to better understand this invention, its application scenarios are not limited to prefabricated building construction on land in safe environments. It can also be applied to construction in contaminated areas where direct access by construction personnel is unsuitable, and even to prefabricated building construction in outer space. Furthermore, when the unmanned prefabricated building construction system of this invention is applied to prefabricated building construction in outer space, the unmanned subsystem and the prefabricated component 100 assembly subsystem can be replaced with equipment or devices adapted to the outer space environment. This only provides one application environment for the unmanned prefabricated building construction system of this invention, but the invention is not limited to this application environment. Therefore, specific equipment or devices adapted to the outer space environment will not be described in detail here.

[0081] It should also be noted that in this embodiment, other functions in the example drone control subsystem 200 are similar to those in existing drones. Known mature technologies for drones can also be applied in this invention. Therefore, this part of the technology will not be described in detail.

[0082] In this embodiment, by setting up a control subsystem 200, a drone subsystem 300, and a prefabricated component assembly subsystem, the control subsystem 200 is deployed outside the construction site, and the drone subsystem 300 is deployed above the construction site. The scheduling drone 310 within the drone subsystem 300 executes scheduling commands over the construction site, and at least one engineering drone 320 flies over the construction site to execute engineering commands. Under this premise, the transporter 410 in the prefabricated component 100 assembly subsystem transports the prefabricated component 100 to the target installation position, and the installation mechanism 420 installs the prefabricated component 100 at the target installation position. This allows the invention to achieve prefabricated building installation operations through the cooperation of the control subsystem 200, the drone subsystem 300, and the prefabricated component 100 assembly subsystem. Since the engineering drone 320 flies over the construction site... The system operates from above, allowing for the execution of engineering commands such as surveying, monitoring, and data transmission at the construction site. This eliminates the need for on-site construction workers. Furthermore, the prefabricated component 100 assembly subsystem assembles the prefabricated component 100 to the target installation position, and the installation mechanism 420 then installs it there. This allows the invention to simultaneously install the prefabricated component 100 to the target installation position during the construction of prefabricated buildings, utilizing the coordination of the control subsystem 200 and the drone subsystem 300, thus eliminating the need for on-site construction workers. This invention solves the technical problems inherent in related technologies where on-site construction workers are exposed to wind, rain, or intense sunlight, posing safety risks. Additionally, the varying skill levels of construction workers can negatively impact the construction efficiency of prefabricated buildings.

[0083] In some specific embodiments, the engineering drone 320 includes:

[0084] Flight body 321, on which a data processor is installed, the data processor being connected to a communication link module; and,

[0085] Measuring device 322 is installed on the flight body 321. Measuring device 322 is used to measure the spatial coordinate information of the construction site. Measuring device 322 is connected to the data processor. The control subsystem 200 can control the data processor to plan the travel path of the transporter 410 according to the spatial coordinate information and navigate the transporter 410 according to the travel path through the communication link module.

[0086] In this embodiment, by setting up the flight body 321 and the measuring device 322, the present invention can directly use the engineering drone 320 to carry out surveying, measurement, layout and monitoring of the construction site without the need for additional equipment, which can reduce costs and effectively ensure the safety of the airspace where the construction site is located.

[0087] It should be specifically and clearly stated that, in this embodiment, the example measuring device 322 is an existing device or equipment used to measure the spatial coordinate information of the target construction area. This embodiment only applies it and does not involve any improvement or design of the structure of the example measuring device 322 itself. Therefore, it will not be described in detail here. However, it can be listed that the example measuring device 322 in this embodiment can be, but is not limited to, a photographic camera capable of oblique photogrammetry modeling in the prior art.

[0088] In some specific embodiments, each engineering drone 320 is also provided with a first connecting member 110 that is spaced apart from the measuring device 322;

[0089] The unmanned aerial vehicle subsystem 300 also includes a first mounting mechanism 340, which can be detachably connected to at least one first connector 110.

[0095] At least two first mounting components 343 are spaced apart on the side of the connecting frame away from the mounting component 422, and all mounting components can be detachably connected to external components.

[0096] In this embodiment, by setting a first connecting frame 341, at least two spaced first mounting members 422342 are installed on the first connecting frame 341, so that the first mounting members 422342 can be detachably connected to the first connecting member 110. This allows the engineering drone 320 to be connected to the first mounting members 422342 according to actual needs during use, thereby enabling the engineering drone 320 to have better working performance.

[0097] It should be specifically and clearly stated that, in this embodiment, the first mounting component 343 on the example first mounting mechanism 340 includes, but is not limited to, a robotic arm, a robotic claw, or an automatic hook as in the prior art.

[0101] The second mounting mechanism 413 is mounted on the mounting surface and is detachably connected to the prefabricated component 100.

[0102] The control subsystem 200 can control the walking component 412 to walk on the construction site according to the path planned by the engineering drone 320, so as to transport the prefabricated component 100 mounted on the second mounting mechanism 413 to the target installation position.

[0103] In this embodiment, by setting up a chassis 411, a walking component 412, and a second mounting mechanism 413, the present invention can drive the prefabricated component 100 placed on the second mounting mechanism 413 to move autonomously within the construction site through the walking component 412, so as to realize the function of transporting the prefabricated component 100 to the target installation position.

[0104] It should be specifically and clearly stated that, in this embodiment, the example walking component 412 may be, but is not limited to, a transportation platform that can achieve autonomous walking under the control of the control subsystem 200 and the tracking and navigation of the unmanned aerial vehicle subsystem 300, and the example second carrying mechanism 413 may be, but is not limited to, a robotic arm, robotic claw, or automatic hook in the prior art.

[0107] The second connecting frame 4131 is mounted on the mounting surface; and...

[0108] At least two second mounting members 4132 are spaced apart and mounted on the side of the connecting frame away from the mounting surface, and each second mounting member 4132 can be detachably connected to any second connecting member 120.

[0113] At least two flip-up members 421 are circumferentially spaced and mounted on the sides of the second connecting frame 4131, and the flip-up members 421 are detachably connected to the third connecting member; and,

[0114] At least two mounting pieces 422, the number of mounting pieces 422 is the same as that of the flipping pieces 421 and they are arranged one-to-one on the side of the second connector 120;

This enables the invention to achieve unmanned installation of the prefabricated component 100 in specific use.

[0117] It should be specifically and clearly stated that, in this embodiment, the example mounting component 422 can be configured according to the specific installation and connection method of each prefabricated component 100. Specifically, the connection between the mounting component 422 and the flipping component 421 is detachable. The example mounting component 422 can be, but is not limited to, an electric wrench, an automatic grouting pipe, or an automatic welding gun.

[0118] Based on the same technical concept, in the second aspect, please refer to Figures 7 to 9 The present invention also proposes an unmanned construction method for prefabricated buildings, which applies the unmanned construction system for prefabricated buildings in the first aspect.

[0119] The unmanned construction method for prefabricated buildings includes the following steps:

[0120] S100: The construction site is surveyed and scanned using the UAV subsystem 300 to form a first database of the construction site in the control subsystem 200; wherein, the first database includes spatial coordinate data information of the construction site;

[0121] In this embodiment, when using the UAV subsystem 300 to survey and scan the construction site, the engineering UAV 320 is mainly used to survey and scan the construction site. After the scan is completed, the control subsystem 200 can process the data measured by the engineering UAV 320, and then combine it with the construction data of the prefabricated building to draw a BIM model of the prefabricated building that can be adapted to the construction site, thus forming the first database of the construction site.

[0122] S200. Based on the first database, the control subsystem 200 controls the engineering drone 320 to measure and lay out the preset construction outline of the prefabricated building at the construction site; wherein, the preset construction outline includes a preset installation path, and multiple target installation positions are formed on the preset installation path at intervals.

[0123] In this embodiment, after the first database is formed, the control subsystem 200 controls the engineering drone 320 to measure and lay out the preset construction outline of the prefabricated building at the construction site. When measuring and laying out the preset construction outline, the engineering drone 320 can be used to perform oblique photogrammetry or only spatial coordinate measurement of the construction site.

[0124] It should be specifically and clearly stated that, in this embodiment, when measuring and setting out the pre-set construction outline at the construction site, attention should be paid to carrying out the measurement and setting out of the pre-set construction outline once after the completion of each segment of construction.

[0125] S300: Using the control subsystem 200 to control the prefabricated component 100 assembly subsystem to transport the prefabricated component 100 to one of the target installation locations and install it;

[0126] S400. Following the preset construction path, repeatedly execute the steps of using the control subsystem 200 to control the prefabricated component 100 assembly subsystem to transport the prefabricated component 100 to one of the target installation positions and install it, until the installation of the prefabricated building is completed.

[0127] In some specific embodiments, the step of controlling the engineering drone 320 to measure and lay out the preset construction outline of the prefabricated building at the construction site using the control subsystem 200, based on the first database, includes:

[0128] S310. Based on the first database and combined with the preset construction data, a BIM model database of prefabricated buildings is formed in the control subsystem 200; wherein, the BIM model database includes multiple prefabricated component 100 models, and the number of prefabricated component 100 models is consistent with the number of prefabricated components 100 and they correspond one-to-one.

[0129] S320. Encode all prefabricated components 100 in the BIM model database to form a preset layout path;

[0130] S330. Based on the preset layout path, the control subsystem 200 controls the engineering drone 320 to measure and lay out the preset construction outline of the prefabricated building at the construction site.

[0131] In some specific embodiments, prior to the step of using the unmanned aerial vehicle subsystem 300 to perform surveying and scanning of the construction site to form a first database of the construction site in the control subsystem 200, the method further includes:

[0132] S500, using engineering drones 320 to survey the construction site to obtain dispatch location;

[0133] The S600 controls and schedules the UAV 310 to fly to the scheduling location to establish a communication link.

[0134] In this embodiment, by setting up a control subsystem 200, a drone subsystem 300, and a prefabricated component assembly subsystem, the control subsystem 200 is deployed outside the construction site, and the drone subsystem 300 is deployed above the construction site. The scheduling drone 310 within the drone subsystem 300 executes scheduling commands over the construction site, and at least one engineering drone 320 flies over the construction site to execute engineering commands. Under this premise, the transporter 410 in the prefabricated component 100 assembly subsystem transports the prefabricated component 100 to the target installation position, and the installation mechanism 420 installs the prefabricated component 100 at the target installation position. This allows the invention to achieve prefabricated building installation operations through the cooperation of the control subsystem 200, the drone subsystem 300, and the prefabricated component 100 assembly subsystem. Since the engineering drone 320 flies over the construction site... The system operates from above, allowing for the execution of engineering commands such as surveying, monitoring, and data transmission at the construction site. This eliminates the need for on-site construction workers. Furthermore, the prefabricated component 100 assembly subsystem assembles the prefabricated component 100 to the target installation position, and the installation mechanism 420 then installs it there. This allows the invention to simultaneously install the prefabricated component 100 to the target installation position during the construction of prefabricated buildings, utilizing the coordination of the control subsystem 200 and the drone subsystem 300, thus eliminating the need for on-site construction workers. This invention solves the technical problems inherent in related technologies where on-site construction workers are exposed to wind, rain, or intense sunlight, posing safety risks. Additionally, the varying skill levels of construction workers can negatively impact the construction efficiency of prefabricated buildings.
