Description

Technical Field

[0001] This invention relates to the field of intelligent construction management technology, specifically to a data center project management method and system based on AR+BIM technology. Background Technology

[0002] BIM technology refers to the creation of a virtual 3D model of a building project, the use of digital technology to provide a complete and consistent building project information database for this model, and the overlay of AR technology on top of BIM technology. Through high-precision positioning, the BIM model of the positioned area is displayed on the screen of a mobile device or through AR glasses, thereby restoring the BIM model to the site environment.

[0003] When building a data center, it is necessary to pre-mark the layout of the server rack system and cable tray system to ensure that the server racks and cable trays are accurately installed in the designated locations and to guarantee the fiber optic cabling requirements. Currently, there are two main pre-marking and positioning methods:

[0004] 1. Workers measure and mark the positions of server racks on the ground of the data center according to the construction drawings. Then, they erect scaffolding and measure and mark the positions of the hangers on the roof. This marking and positioning method requires multiple people to work together and repeatedly look at the drawings to confirm the positions. The marking efficiency is low, and working at height is also relatively dangerous. Climbing up and down and erecting scaffolding also delays the construction process.

[0005] 2. In some data center projects, AR+BIM technology is used to assist construction workers in pre-marking, verifying, and maintaining the model. During the marking phase, workers can visually see the model's location through mobile devices. When a worker walks to the corner of the model, he will inform another worker to mark it there. Although this method eliminates the reliance on drawings and measuring equipment on-site and has high marking accuracy, in actual marking, the AR+BIM model lacks a direct connection with the final marking, requiring multiple people to collaborate. Errors can occur during communication and transmission, and high-altitude operations are also required.

[0006] In summary, there is a need for a data center project management method based on AR+BIM technology that offers higher marking efficiency and security. Summary of the Invention

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0044] Figure 1 A schematic diagram of the data center project management system based on AR+BIM technology of the present invention is shown; Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] To address the technical issues mentioned in the background section, the following data center project management method based on AR+BIM technology is proposed:

[0048] The present invention provides a data center project management method based on AR+BIM technology, the method comprising the following steps:

[0049] S1. Construction of the original data center model, resulting in the original data center model:

[0050] Back-end designers create the original building model in the BIM model cloud platform based on the construction drawings;

[0051] The environmental model acquisition terminal enters the data center site, collects original building images of various locations in the data center, and uploads them to the BIM model cloud platform.

[0052] Back-end designers use the BIM model cloud platform to match the original building images with the original building model to obtain the original model of the data center.

[0053] S2. Data Center Construction Model Setup:

[0054] The BIM model cloud platform combines construction drawings with the original data center model, and draws the cabinet system on the ground of the original data center model to obtain the first BIM model; the first BIM model includes cabinet models and communication equipment models of various sizes;

[0055] The BIM model cloud platform combines construction drawings with the original data center model, and draws the cable tray system on the top surface of the original data center model to obtain a second BIM model; the second BIM model includes cable tray model, hanger model, and optical cable model;

[0056] S3, Construction Pre-marking:

[0057] The marking control terminal enters the data center site. The marking control terminal has a built-in touch screen, environmental camera component, marking component, real-time positioning module, BIM model storage module, and BIM model display module. The marking component is always within the lens coverage area of ​​the environmental camera component.

[0058] The central control terminal downloads the first BIM model and the second BIM model from the BIM model cloud platform, and both the first BIM model and the second BIM model are stored in the BIM model storage module.

[0059] Operators view the first or second BIM model through a touch screen, adjust the marking components, and finally print the first entity mark on the ground of the data center and the second entity mark on the top surface of the data center. The first entity mark includes the installation area, reserved holes, reserved slots, and reserved areas of each size and model of cabinet; the second entity mark includes the installation area, reserved holes, reserved slots, and reserved areas of each size and model of hanger.

[0060] S4. Construction personnel install server rack systems and cable tray systems:

[0061] S5. The supervisors use the BIM model display module in the mobile device to inspect the cabinet system and cable tray system. After the inspection is passed, the next step is carried out. During the inspection, the workers hold the mobile device and compare the first BIM model and the second BIM model displayed on the mobile device with the physical equipment to judge whether the distribution and installation position are qualified.

[0062] S6. Maintenance personnel can perform maintenance on the cabinet system and cable tray system through the BIM model display module in the mobile device. During operation and maintenance, the first BIM model and the second BIM model displayed in the mobile device allow workers to intuitively see the internal components of the cabinet system and cable tray system, assisting them in quickly determining the inspection, disassembly, and maintenance plan.

[0063] As an improvement to the above technical solution, the specific steps for printing the first entity mark on the data center ground are as follows:

[0064] Adjust the marker components and environmental camera components to align with the data center floor;

[0065] The environmental camera component transmits real-scene images to the touch screen for display; the real-time positioning module uploads real-time coordinates to the BIM model display module, and the BIM model display module retrieves the local first BIM model corresponding to the real-time coordinates; the local first BIM model and the real-scene image coexist and are displayed together on the touch screen, and the real-scene image always contains a marker component;

[0066] The operator adjusts the alignment of the marking component with the boundary in the local first BIM model, and then controls the marking component to print the first entity mark on the data center floor.

[0067] As an improvement to the above technical solution, the specific steps for printing the second entity mark on the top surface of the data center are as follows:

[0068] Adjust the marker components and environmental camera components to align with the top surface of the data center;

[0069] The environmental camera component transmits real-scene images to the touch screen for display; the real-time positioning module uploads real-time coordinates to the BIM model display module, and the BIM model display module retrieves the corresponding local second BIM model based on the real-time coordinates; the local second BIM model and the real-scene images coexist and are displayed together on the touch screen, with marker components always present in the real-scene images;

[0070] The operator adjusts the alignment of the marking component with the boundary in the local second BIM model, and then controls the marking component to print the boundary entity marking of the cable tray on the data center floor.

[0071] As an improvement to the above technical solution, the coexistence and combination display specifically involves: the BIM model display module matching the real scene image with the original building image of the local model, so that the local model is displayed in the corresponding area of ​​the real scene image; this step achieves the matching and fusion of the real scene image and the local model, which is a local first BIM model and a local second BIM model.

[0072] In this embodiment, the local BIM model, real-scene image, and marking component are displayed together on the touch screen. When the marking component is aligned with the corner of the local base map model, the marking component can be controlled to move, and the marking component can print physical marks on the wall or ground. In this way, the marking is more intuitive by combining virtual and real methods, eliminating the need for repeated measurements and multiple people to collaborate and communicate repeatedly to confirm, which greatly improves the marking efficiency and expands the application scenarios of AR+BIM technology.

[0073] Example 2

[0074] like Figure 1 As shown, to address the technical issues in the background section, a data center project management system based on AR+BIM technology is presented. The specific content of the project management system is as follows:

[0075] This includes a BIM model cloud platform, which connects to an environmental model acquisition terminal, mobile devices, and a marking control terminal. The environmental model acquisition terminal is used to acquire original building images and upload them to the BIM model cloud platform. The BIM model cloud platform is used to draw and store the BIM model. The marking control terminal is used to mark entities based on the BIM model.

[0076] The BIM model cloud platform includes an external communication module, a BIM model database, a BIM model building module, a BIM model retrieval module, and a location receiving module.

[0077] The marking control terminal includes a main unit housing, inside which a control motherboard and a touch screen are installed. The control motherboard has embedded a power supply module, a Bluetooth module, a main control processor, and a first wireless communication module. The main control processor has built-in BIM model storage and BIM model display modules. The outer side of the main unit housing is rotatably connected to a support component. One end of the support component is fitted with a marking component, and the other end is fitted with an environmental camera component. The environmental camera component and the marking component are positioned opposite each other. The bottom of the main unit housing is equipped with casters, and the side wall of the main unit housing has a handle.

[0078] The rotating support assembly allows for easy adjustment of the marking position of the marking assembly, enabling marking of the data center's floor, side walls, and ceiling, thus broadening its applicability.

[0079] As an improvement to the above technical solution, the support assembly includes a first support plate, a second support plate, and a third support plate. The first support plate is rotatably connected to the outer side of the main unit chassis. The end of the first support plate is hinged to the end of the second support plate. The side wall of the second support plate is provided with a connecting plate.

[0080] When the second support plate is unfolded, it is rotatably fixed to the top of the first support plate, and the second support plate and the first support plate are continuous as one piece; when the second support plate is folded, the second support plate rotates and is placed side by side with the first support plate; a third support plate is slidably connected to the inner wall of the first support plate, and a slider is provided on the back of the third support plate. A marking component is installed at one end of the outer side of the third support plate, and an environmental camera component is installed at the other end; the third support plate is fixed by a locking knob.

[0081] The combination of the first, second, and third support plates allows the system to be folded together to meet the needs of ground marking, or unfolded and extended to meet the marking needs of side walls and the top surface; it is easy to adjust and more efficient to change.

[0082] In this way, when it is necessary to mark high-altitude areas, workers can operate the marking control terminal on the ground. The marking components and environmental camera components are located on the roof of the data center. Operators can see the real-time location model and marking components through a touch screen. When the marking components match the model, the movement of the marking components can be controlled, enabling accurate marking of high-altitude areas from the ground, eliminating the need for high-altitude marking operations and greatly improving the deployment efficiency of the cable tray system.

[0083] As an improvement to the above technical solution, the environmental model acquisition terminal includes an environmental acquisition camera, an acquisition positioning module, and a second wireless communication module. The acquisition positioning module is deployed at various corners of the data center site to facilitate the environmental acquisition camera's measurement of the site dimensions.

[0084] The data acquisition and positioning module can be deployed at the boundary of the data center to facilitate the production of a positioning coordinate system. After the environmental acquisition camera enters the data center site, it can identify and scan the original building images to meet the needs of establishing the original model of the data center.

[0085] As an improvement to the above technical solution, the environmental camera component includes a fixed plate, a camera, and a real-time positioning module. The real-time positioning module is provided on one side of the fixed plate and the camera is provided on the other side. LED beads are provided on the outer ring of the camera, and the camera is located directly above the hole in the main frame.

[0086] The camera is integrated with a real-time positioning module. The real-time positioning module can collect real-time coordinates, which can be used as the basis for retrieving the BIM model display module, and only the local base map model associated with the real-time coordinates can be retrieved. The camera can collect images of the area to be marked in real time so that the local base map model can be combined with the real-time image.

[0087] The design of the camera's position relative to the main frame ensures that the four boundary markers are always in the real-time image, making it easy for operators to quickly and accurately determine the marker positions.

[0088] The design of the LED beads can enhance the brightness of the area covered by the camera and improve image clarity.

[0089] Example 3

[0090] Based on the above embodiments, this embodiment further provides the following:

[0091] When marking the cabinet boundary, the marking component cannot cover such a large area; when marking other reserved mounting holes and areas, the marking areas are small and vary. To solve these problems and satisfy the marking requirements for cabinet boundary marking, marking of various reserved mounting holes and areas, the following solution is proposed:

[0092] The marking component includes a main frame, which is a rectangular frame structure. The main frame is assembled and connected to the support component. Movable positioning components are installed at the four corners of the main frame. The four movable positioning components are located on the diagonals of the main frame and slide along the diagonals. Boundary marking plates are fixedly connected to the inner ends of the four movable positioning components. Each boundary marking plate has an L-shaped cross-section. The four boundary marking plates are set independently and arranged in a rectangular pattern. The four boundary marking plates are located in the inner holes of the main frame and are positioned directly opposite the environmental camera component.

[0093] As an improvement to the above technical solution, the movable positioning component includes a movable plate and a drive gear. The boundary marking plate is located at the inner end of the movable plate. A guide frame is provided at the bottom corner of the main frame. The movable plate slides through the guide frame. The drive gear is installed on the bottom surface of the main frame and meshes with the movable plate. The drive gear is located on the inner side of the guide frame. The drive gear is used to drive the movable plate to move along the diagonal of the main frame, thereby changing the marking range of the boundary marking plate.

[0094] The drive gear is connected to the drive motor, which is mounted on the bottom of the main frame. The drive motor drives the drive gear to rotate, which in turn engages with the drive plate to move diagonally. The guide frame guides the movement of the drive plate, thereby changing the marking position of the boundary marker plate. The four drive gears and the drive plate move synchronously, which in turn drives the four boundary marker plates to move synchronously, changing the area enclosed by the four boundary marker plates.

[0095] In this embodiment, the active positioning component can drive the boundary marker plate to extend and retract along the diagonal. In this way, the overall area enclosed by the four boundary marker plates can be changed simultaneously, thereby meeting the marking requirements of each reserved mounting hole and reserved mounting area, making the marking range of the marker plate wider.

[0096] The boundary marking plates are designed in an L-shape and arranged in a rectangular pattern with four plates. This allows for the selection of a single boundary marking plate with a suitable opening orientation based on the location to be marked when marking cabinet boundaries or other large-sized equipment boundaries, thus meeting the marking needs of large areas. In addition, the L-shaped structure can also meet the marking needs of circular holes and slots, as long as the boundary marking plate is tangent to the outer ring of the hole or slot model.

[0097] To ensure the boundary markers fulfill the aforementioned functions, the following issue needs to be addressed: when marking large areas, any one of the four boundary markers can operate independently; however, when marking small areas, all four boundary markers must operate synchronously. To resolve this issue, the following solution is proposed:

[0098] The boundary marking plate has a nozzle embedded inside, and the movable plate has a liquid guide tube embedded inside. The liquid guide tube is connected to the paint supply component, which is used to discharge paint of different colors to the boundary marking plate. A solenoid valve is installed on the liquid guide tube.

[0099] As an improvement to the above technical solution, the paint supply assembly includes two sets of paint storage boxes. Each paint storage box has three independent liquid storage chambers. Each of the three liquid storage chambers is equipped with an independent solenoid valve. The three solenoid valves are connected in parallel to the liquid pump. The outlet of the liquid pump is connected to the main pipe. The main pipe is connected to two boundary marking plates through the branch hoses. Each paint storage box supplies liquid to the boundary marking plates on both sides.

[0100] The solenoid valves of the paint storage box, the liquid guide tube, the real-time positioning module, and the camera are all wirelessly connected to the marking control terminal.

[0101] Each boundary marking plate uses a spray-paint marking method. The paint supply component draws paint to the boundary marking plate to be worked on, and then the paint is sprayed downwards through the nozzle to achieve the boundary marking. This method is simple to control and can be arbitrarily controlled as needed, resulting in higher flexibility and efficiency. Different colors of paint can be supplied according to different equipment to be installed. Thus, workers can quickly identify the equipment to be installed based on the marking color during construction, further improving equipment installation efficiency and accuracy.

[0102] When using the above spraying method, because the spray nozzle needs to spray different colors of paint, paint residue remains in the main hose, branch hoses, and inside the spray nozzle. As a result, when the paint is changed next time, the initial spray of paint colors is chaotic, and the spraying time is short. Therefore, the marking colors are easily confused, affecting the judgment of subsequent workers. To solve the above problems, the following solution is proposed:

[0103] The bottom surface of the boundary marking plate is covered with a shielding plate. The bottom surface of the movable plate is symmetrically provided with a constraint groove. A spring is installed inside the constraint groove. The constraint groove is located inside the guide frame. A constraint block is provided on the inner wall of the inner end of the shielding plate. The constraint block is slidably embedded in the constraint groove and abuts against the inner end of the spring. The bottom surface of the guide frame is provided with a traction assembly, which includes a traction motor and a traction rope. The traction motor is installed on the bottom surface of the guide frame. A traction wheel is provided at the output end of the traction motor. A traction rope is wound around the outer wall of the traction wheel. The end of the traction rope is fixedly connected to the shielding plate.

[0104] When not in use, the shield should be placed below to protect the nozzle and prevent dust and impurities from entering.

[0105] During the initial painting stage, the masking plate remains in a masking state for 0.5-1 second, allowing residual paint to be sprayed onto the masking plate instead of onto the wall. After the holding time ends, the traction motor drives the traction wheel to rotate, which in turn pulls and retracts the traction rope. The masking plate is pulled away from the boundary marker plate, and the constraint block moves along the constraint groove and compresses the spring until the masking plate is completely disengaged from the boundary marker plate. In this way, the boundary marker plate can spray the desired color of paint onto the wall. After the painting is completed, the traction motor drives the traction wheel to reverse, and the spring drives the masking plate to reset.

[0106] As the movable platform moves, the traction motor rotates synchronously, causing the traction rope to be released, thus meeting the subsequent traction needs of movable platforms of different lengths.

[0107] In operation, this embodiment is as follows:

[0108] When marking the ground of a data center:

[0109] At this time, the second support plate is folded together in parallel with the side of the first support plate, and the third support plate can be vertically adjusted along the first support plate so that the marking component is in a suitable position above the ground. Finally, the third support plate is fixed on the second support plate by locking the knob.

[0110] The environmental camera component, touch screen, and marking component are activated. The real-time local first BIM model, boundary marker plate, and real-scene image are displayed together on the touch screen. When the boundary marker plate moves next to the equipment, the predetermined spray color is selected according to the equipment type. Then, the boundary marker plate with the appropriate opening orientation is selected. The corner of the boundary marker plate is adjusted to align with the corner of the local first BIM model. Then, the liquid pump, color solenoid valve, and boundary marker plate solenoid valve are activated. The boundary marker plate sprays out paint. The first sprayed paint is blocked by the shielding plate. Then, the traction component drives the shielding plate to retract, exposing the nozzle. Finally, the first solid mark is sprayed on the ground.

[0111] Repeat the above steps to mark the placement locations of the data center ground equipment. Since most of the equipment placed on the ground is large, only one paint spraying plate needs to work at a time. If an area needs to be painted with pre-drilled holes, the four drive gears can be controlled to move synchronously, so that the four movable plates and boundary marking plates move synchronously to adapt to the size requirements of the pre-drilled holes.

[0112] When it is necessary to mark the roof of the data center, rotate the support assembly upwards, then rotate the second support plate to align with the first support plate, and move the third support plate to adjust the height of the marking assembly so that the environmental camera assembly and the marking assembly are aligned upwards with the roof.

[0113] Adjust the four boundary marker plates and select appropriate colors, so that the four boundary marker plates can simultaneously spray out the second entity mark.
