Description

Technical Field

[0001] This invention relates to the field of interior decoration technology, and more specifically, to a production system for collaborative design schemes of BIM and prefabricated interior decoration. Background Technology

[0002] Currently, in construction scenarios based on BIM and prefabricated interior decoration collaborative design, on-site personnel frequently need to use laptops for tasks such as model viewing, dimension verification, scheme adjustment, and production data synchronization. Traditional laptops only have basic functions and can only be used in fixed scenarios such as flat desktops. However, the environment of prefabricated construction sites is complex and often lacks a suitable operating platform. When performing mobile operations such as walking inspections, on-site verification, and point confirmation, the equipment can only be held with one hand, making it difficult to operate with both hands simultaneously, which greatly affects the user experience and work efficiency.

[0003] Existing laptop supports, stands, or portable wearable structures generally have limited functions, mostly only providing simple support or portability. They cannot flexibly switch between storage, desktop support, and chest carrying, making it difficult to meet the diverse usage needs of construction sites. They also cannot provide reliable, comfortable, and efficient on-site usage conditions for BIM mobile terminals, thus restricting the digital collaborative efficiency of the entire process of prefabricated interior decoration from design, measurement to construction and verification. Therefore, we provide a production system for collaborative design solutions based on BIM and prefabricated interior decoration. Summary of the Invention

[0004] The purpose of this invention is to provide a production system for collaborative design schemes of BIM and prefabricated interior decoration, in order to solve the problems mentioned in the background art above: Some existing laptops cannot be flexibly switched between being stored and carried, used on a desktop, or worn on the chest, making it difficult to meet the diverse usage needs of construction sites and failing to provide reliable, comfortable, and efficient on-site usage conditions for BIM mobile terminals.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A production system based on BIM and prefabricated interior decoration collaborative design schemes includes a laptop. Each laptop has a first support arm rotatably connected to one of its two sides. The other end of each first support arm is fixedly connected to a fixed sleeve. The fixed sleeve contains a positioning mechanism. A second support arm is fitted onto the outside of the fixed sleeve, rotatably connected to it. The other end of the second support arm is fixedly connected to a fixed rod. The fixed rod has a first groove inside, and a first sliding rod is slidably connected inside the groove. A clamping rod is rotatably connected between the two first sliding rods. A silicone sleeve is fitted onto the outside of the clamping rod, and the silicone sleeve is fixedly connected to the first sliding rod. The system is divided into two modes: 1. Storage mode: The first and second support arms are folded and stored on the sides of the laptop, and the clamping rod is stored at the back. The clamping rod can be bent into an arc shape to act as a portable handle for easy carrying. 2. Desktop stand mode: Pressing the movable sleeve separates the locking block from the slot, causing the second support arm to rotate downwards. To achieve the desired angle, release the movable sleeve to lock it in place. The second support arm and the clamping rod together form a desktop support foot, raising the laptop to a comfortable operating angle suitable for temporary desktop work on the interior decoration site, facilitating BIM model viewing and editing. Third, in chest-back carrying mode, press the movable sleeve again to separate the insert rod from the slot, unfolding the first and second support arms to form a double-shoulder carrying structure. The clamping rod fits snugly against the back of the neck, and the silicone sleeve provides cushioning and anti-slip, stably supporting the laptop in front of the user's chest, freeing their hands. This allows for easy operation of the BIM model and verification of prefabricated component dimensions while walking on the construction site. It allows for free switching between three functional modes: storage handle, desktop stand, and chest-back carrying, perfectly matching the mobile work, temporary desktop work, and portability needs of prefabricated interior decoration construction sites. It is deeply integrated with the BIM collaborative design process. A miniature laser ranging module is fixedly connected to one side of the laptop, embedded in the front left side frame of the laptop, near the keyboard area, flush with the outer surface of the body, and not protruding from the casing.

[0006] Preferably, the positioning mechanism includes a movable sleeve slidably connected to a fixed sleeve. A support sleeve is provided inside the movable sleeve and is fixedly connected to the fixed sleeve. A first through groove is formed inside the support sleeve, and a movable frame is slidably connected inside the first through groove. Two inclined blocks are slidably connected to corresponding sides of the movable frame and are fixedly connected to the movable sleeve. One of the inclined blocks has a groove inside, and a locking block is slidably connected inside the groove. The locking block is fixedly connected to the movable frame and penetrates the fixed sleeve, extending to the fixed sleeve. The locking block is slidably connected to the fixed sleeve outside the fixed sleeve. The second support arm has a locking groove inside. The locking groove works in conjunction with the locking block. When the user applies inward pressure to the movable sleeve, the movable sleeve slides inward along the fixed sleeve and drives the inclined block to move synchronously. During the movement, the inclined block squeezes the movable frame. During the movement, the movable frame squeezes the second sliding rod through the inner wall of the second sliding groove, thereby achieving drive control of the insertion rod and controlling the engagement and disengagement state between the insertion rod and the slot. When the insertion rod and the slot are separated, the locking state between the first support arm and the second support arm is released.

[0007] Preferably, a second through groove is provided on one side of the movable sleeve. The second through groove is used in conjunction with the locking block. The second through groove is connected to the groove. The locking block is simultaneously accommodated inside the second through groove and the groove. When the user applies pressure to the movable sleeve and causes it to move axially, the locking block can be provided with corresponding movement clearance space under the combined action of the second through groove and the groove, thereby avoiding the locking block from hindering or interfering with the normal movement of the movable sleeve.

[0008] Preferably, a second sliding groove is provided on each of the corresponding two sides of the movable frame. A second sliding rod is slidably connected inside the second sliding groove. An insert rod is fixedly connected between the two second sliding rods. The insert rod passes through the fixed sleeve and extends to the outside of the fixed sleeve. The insert rod is slidably connected to the fixed sleeve. A slot is provided on each of the corresponding two sides of the notebook. The slot works in conjunction with the insert rod. When the user presses the movable sleeve, the movable sleeve drives the movable frame to move radially. Since the second sliding groove is inclined, it will exert a squeezing and guiding effect on the second sliding rod through the inner wall of the second sliding groove, driving the second sliding rod to move axially. Then, the second sliding rod drives the insert rod to move axially synchronously, thereby realizing the insertion and disengagement between the insert rod and the slot.

[0009] Preferably, a third sliding groove is provided inside the first support arm near the end of the laptop. A third sliding rod is slidably connected inside the third sliding groove. The third sliding rod is fixedly connected to the laptop. During the rotation of the first support arm relative to the laptop, the third sliding rod slides relative to the trajectory of the third sliding groove. The movement stroke of the third sliding rod is limited by the two end walls of the third sliding groove, thereby constraining the rotation angle of the first support arm.

[0010] Preferably, a tension spring is provided between the first slide groove and the first slide rod. One end of the tension spring is fixedly connected to the fixed rod, and the other end of the tension spring is fixedly connected to the first slide rod. When the user needs to attach the abutment rod to the back of the neck for support, an outward pulling force can be applied to the abutment rod. Under the action of the pulling force, the abutment rod deforms from its initial long strip structure and gradually bends into an arc-shaped structure that conforms to the contour of the back of the neck. During this process, the abutment rod simultaneously drives the first slide rod to slide outward along the first slide groove. During the sliding process, the first slide rod stretches the tension spring, allowing the tension spring to accumulate elastic restoring force. When the user finishes the operation and no longer uses the abutment rod, the external force acting on the abutment rod disappears, and the tension spring returns to its elastic restoring state. Under the action of the restoring force, the first sliding rod is pulled back inward along the first sliding groove to the initial position. A spring is provided between the movable sleeve and the supporting sleeve. One end of the spring is fixedly connected to the movable sleeve, and the other end of the spring is fixedly connected to the supporting sleeve. When the user needs to adjust the support height or lock the position, an inward pressing force can be applied to the movable sleeve. Under the action of the pressure, the movable sleeve moves inward along the supporting sleeve and compresses the spring, causing the spring to generate elastic potential energy. When the user stops pressing the movable sleeve and completes the position adjustment, the external force applied to the movable sleeve disappears, and the spring pushes the movable sleeve upward under its own elastic restoring force, causing the movable sleeve to move upward along the supporting sleeve and return to the initial position.

[0011] Preferably, both the first slide groove and the first slide rod have square cross-sections. The first slide rod can slide in a straight line within the first slide groove. Since both the first slide groove and the first slide rod have square cross-sections, their cooperation can circumferentially limit the first slide rod, effectively preventing circumferential rotation, offset, or wobbling within the first slide groove. This ensures that the first slide rod can only make stable linear reciprocating motion along the extension direction of the first slide groove. The third slide groove has an arc-shaped structure, with its center coinciding with the center of the rotation axis of the first support arm. This ensures that the arc trajectory of the third slide groove is consistent with the rotation trajectory of the first support arm. Through the cooperation of the third slide groove and the third slide rod located within it, the rotation range of the first support arm can be effectively limited. The movable frame has a parallelogram cross-section. Because the movable frame adopts a parallelogram cross-sectional shape, when the user applies axial pressure to the movable sleeve, the axial movement of the movable sleeve is converted into radial movement of the movable frame, achieving a reasonable conversion of the direction of movement.

[0012] Preferably, the top of the card block is provided with a first chamfer, which is located on both sides of the top of the card block. By providing the first chamfer on both sides of the top of the card block, it can play a guiding role when the card block and the card slot are engaged, effectively reducing the difficulty of alignment between the card block and the card slot, avoiding rigid interference or jamming between the top edge of the card block and the inner wall of the card slot, so that the card block can slide into the card slot more smoothly and accurately to achieve engagement. The outer end of the insertion rod away from the second slide rod is provided with a second chamfer. The second chamfer can form a guiding structure when the insertion rod and the slot are engaged, making it easier for the insertion rod to be smoothly inserted into the slot, reducing frictional resistance and alignment deviation during the insertion process.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1) This production system based on BIM and prefabricated interior decoration collaborative design scheme, when in use, utilizes a first and second support arm on both sides of the laptop body that can rotate in multiple stages and have adjustable angles. Combined with a bendable and resettable clamping rod and a composite positioning mechanism, it can flexibly switch between two usage modes: desktop support and chest-back support. In desktop operation scenarios, unfolding the support arm can raise the laptop to a comfortable operating height, ensuring stability and durability without wobbling. In on-site mobile operation scenarios, unfolding the support arm and using the clamping rod to conform to the neck and torso provides stable support for the laptop in front of the chest, completely freeing the hands. This facilitates operation of the BIM model and verification of prefabricated component dimensions while walking. This structure is scientifically designed, reliable, and comfortable to wear, effectively adapting to the diverse working environments of prefabricated interior decoration construction sites, significantly improving the environmental adaptability and on-site work efficiency of the mobile workstation.

[0014] 2) When using this production system based on BIM and prefabricated interior decoration collaborative design scheme, the overall structure is compact and simple. The supporting components can be completely folded and stored on both sides of the laptop body, and the clamping rod can also be stored on the back of the laptop and bent into an arc-shaped handle to achieve a portable carrying function. It occupies little space and is extremely convenient to carry and store. At the same time, this invention integrates a miniature laser ranging module on the side of the laptop body, which can perform high-precision non-contact dimensional measurement of prefabricated components such as wall panels, floors, and internal and external corners on the construction site, and synchronize the measurement data to the BIM collaborative design software in real time, thereby improving the integration level of prefabricated interior decoration collaborative design and digital construction.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0018] Please see Figures 1 to 11The system is based on BIM and prefabricated interior decoration collaborative design scheme production system, including a laptop 1. First support arms 2 are rotatably connected to both sides of the laptop 1. A fixed sleeve 3 is fixedly connected to the other end of each first support arm 2. A positioning mechanism 10 is installed inside the fixed sleeve 3. A second support arm 4 is fitted onto the outside of the fixed sleeve 3, and is rotatably connected to the fixed sleeve 3. A fixed rod 5 is fixedly connected to the other end of the second support arm 4. A first sliding groove 6 is opened inside the fixed rod 5, and a first sliding rod 7 is slidably connected inside the first sliding groove 6. A clamping rod 8 is rotatably connected between the two first sliding rods 7. A silicone sleeve 9 is fitted onto the outside of the clamping rod 8, and is fixedly connected to the first sliding rod 7. The system is divided into: 1. Storage mode, first support... Arm 2 and the second support arm 4 are folded and stored on both sides of the laptop 1. The clamping rod 8 is stored on the back of the laptop 1. The clamping rod 8 can be bent into an arc shape to serve as a portable handle for easy carrying. Second, in desktop stand mode, press the movable sleeve 12 to separate the locking block 18 from the slot 19, rotate the second support arm 4 downward to a suitable angle, and release the movable sleeve 12 to lock it. The second support arm 4 and the clamping rod 8 together form a desktop support foot, raising the laptop 1 to a comfortable operating angle suitable for temporary desktop work on-site in interior decoration, facilitating BIM model viewing and editing. Third, in chest carry mode, press the movable sleeve 12 again to separate the insertion rod 22 from the slot 23, unfold the first support arm 2 and the second support arm 4 to form a double shoulder carry structure, so that the clamping rod 8 and the back of the neck are connected. The silicone sleeve 9 provides cushioning and anti-slip, stably supporting the laptop 1 against the user's chest, freeing their hands and facilitating hands-free operation of the BIM model and verification of prefabricated component dimensions while walking on the construction site. It allows for seamless switching between three modes: storage handle, desktop stand, and chest carry, perfectly matching the mobile work, temporary desktop work, and portability needs of prefabricated interior decoration construction sites. Deeply integrated with the BIM collaborative design process, a miniature laser ranging module 11 is fixedly connected to one side of the laptop 1. The module is embedded in the front left side bezel of the laptop 1, near the keyboard area, flush with the outer surface of the casing, and does not protrude from the shell. After opening the BIM model on the construction site, the user activates the miniature laser ranging module 11 to emit a laser, and clicks on the site measurement in the BIM plugin interface. The measurement button synchronously starts the control module, enabling data acquisition and transmission. The laser emitting unit emits laser pulses towards the target component, such as a wall panel, ground, or corner, while the receiving unit captures the reflected signal. The signal processing chip calculates the time difference of flight and converts it into a straight-line distance. The data is then transmitted to the BIM collaboration software, which automatically updates the BIM model. After receiving the distance data, the software automatically matches the selected component in the current view and updates the component's length, height, flatness, and other parameters based on the measurement direction. The measurement posture is consistent with the BIM operation posture, eliminating the need for equipment flipping or additional handheld tools, thus achieving synchronous completion of operation and measurement. The module is integrated with the laptop body, requiring no additional equipment and facilitating portability and management on the construction site. Measurement data directly drives BIM model updates, enabling digital collaboration.

[0019] Furthermore, the positioning mechanism 10 includes a movable sleeve 12, which is slidably connected to a fixed sleeve 3. A support sleeve 13 is provided inside the movable sleeve 12, and is fixedly connected to the fixed sleeve 3. A first through groove 14 is formed inside the support sleeve 13, and a movable frame 15 is slidably connected inside the first through groove 14. Two inclined blocks 16 are slidably connected to corresponding sides of the movable frame 15, and are fixedly connected to the movable sleeve 12. One of the inclined blocks 16 has a groove 17 inside, and a locking block 18 is slidably connected inside the groove 17. The locking block 18 is fixedly connected to the movable frame 15, passes through the fixed sleeve 3, and extends to the outside of the fixed sleeve 3. The second support arm 4 has a locking groove 1 inside. 9. The slot 19 and the block 18 work together. When the user applies inward pressure to the movable sleeve 12, the movable sleeve 12 slides inward along the fixed sleeve 3 and drives the inclined block 16 to move synchronously. During the movement, the inclined block 16 squeezes the movable frame 15, causing the movable frame 15 to generate a corresponding displacement in the first through groove 14. During the movement, the movable frame 15 squeezes the second slide rod 21 through the inner wall of the second slide groove 20, thereby realizing the drive control of the insertion rod 22 and controlling the engagement and disengagement state between the insertion rod 22 and the slot 23. When the insertion rod 22 and the slot 23 are separated, the locking state between the first support arm 2 and the second support arm 4 is released, and the user can freely rotate the first support arm 2 and the second support arm 4 to complete the unfolding, angle adjustment and form switching of the support structure.

[0020] Furthermore, a second through groove 28 is provided on one side of the movable sleeve 12. The second through groove 28 is used in conjunction with the locking block 18. The second through groove 28 is interconnected with the groove 17. The locking block 18 is simultaneously accommodated inside the second through groove 28 and the groove 17. When the user applies pressure to the movable sleeve 12 and causes it to move axially, the second through groove 28 and the groove 17 work together to provide the locking block 18 with corresponding space for movement, thereby preventing the locking block 18 from obstructing or interfering with the normal movement of the movable sleeve 12, and ensuring that the movable sleeve 12 can smoothly and steadily complete the axial displacement in the preset direction.

[0021] Furthermore, the corresponding two sides of the movable frame 15 are provided with second sliding grooves 20, and the interior of the second sliding grooves 20 is slidably connected with second sliding rods 21. The two second sliding rods 21 are fixedly connected with a plug rod 22. The plug rod 22 passes through the fixed sleeve 3 and extends to the outside of the fixed sleeve 3. The plug rod 22 is slidably connected with the fixed sleeve 3. The corresponding two sides of the notebook 1 are provided with slots 23. The slots 23 are used in conjunction with the plug rod 22. When the user presses the movable sleeve 12, the movable sleeve 12 drives the movable frame 15 to move radially. Since the second sliding grooves 20 are inclined, the movable frame 15 will form a squeezing and guiding effect on the second sliding rods 21 through the inner wall of the second sliding grooves 20 during the radial movement, driving the second sliding rods 21 to move axially. Then, the second sliding rods 21 drive the plug rod 22 to move axially in sync, thereby realizing the insertion and disengagement between the plug rod 22 and the slot 23, and completing the locking and unlocking control between the first support arm 2 and the second support arm 4 and the notebook 1.

[0022] Furthermore, a third slide groove 24 is provided inside the first support arm 2 near the end of the laptop 1. A third slide rod 25 is slidably connected inside the third slide groove 24. The third slide rod 25 is fixedly connected to the laptop 1. During the rotation of the first support arm 2 relative to the laptop 1, the third slide rod 25 slides relative to the trajectory of the third slide groove 24. The movement stroke of the third slide rod 25 is limited by the two end walls of the third slide groove 24, thereby constraining the rotation angle of the first support arm 2 and preventing the first support arm 2 from rotating too much or exceeding the preset range during the rotation process.

[0023] Furthermore, a tension spring 26 is provided between the first slide groove 6 and the first slide rod 7. One end of the tension spring 26 is fixedly connected to the fixed rod 5, and the other end of the tension spring 26 is fixedly connected to the first slide rod 7. When the user needs to attach the abutment rod 8 to the back of the neck for support, an outward pulling force can be applied to the abutment rod 8. Under the action of the pulling force, the abutment rod 8 deforms from its initial long strip structure and gradually bends into an arc-shaped structure that conforms to the contour of the back of the neck. During this process, the abutment rod 8 simultaneously drives the first slide rod 7 to slide outward along the first slide groove 6. During the sliding process, the first slide rod 7 stretches the tension spring 26, allowing the tension spring 26 to accumulate elastic restoring force. When the user finishes the operation and no longer uses the abutment rod 8, the external force acting on the abutment rod 8 disappears. Under the action of its own elastic restoring force, the tension spring 26 pulls the first slide rod 7 back inward along the first slide groove 6 to the initial position. The first slide rod 7 then drives the abutment rod 8 to return to its original position, causing the abutment rod 8 to bend from the arc shape. The arc shape is restored to a long strip shape, realizing the automatic return and storage of the overall structure. A spring 27 is provided between the movable sleeve 12 and the support sleeve 13. One end of the spring 27 is fixedly connected to the movable sleeve 12, and the other end of the spring 27 is fixedly connected to the support sleeve 13. When the user needs to adjust the support height or lock the position, an inward pressing force can be applied to the movable sleeve 12. Under the action of the pressure, the movable sleeve 12 moves inward along the support sleeve 13 and compresses the spring 27, causing the spring 27 to generate elastic potential energy. When the user stops pressing the movable sleeve 12 and completes the position adjustment, the external force applied to the movable sleeve 12 disappears. Under the action of its own elastic restoring force, the spring 27 pushes the movable sleeve 12 upward, causing the movable sleeve 12 to move upward along the support sleeve 13 and return to the initial position, thereby realizing the automatic reset and positioning function of the movable sleeve 12 and ensuring the stability and reliability of the overall support structure during use.

[0024] Furthermore, both the first slide groove 6 and the first slide rod 7 have square cross-sections. The first slide rod 7 can slide in a straight line within the first slide groove 6. Since both the first slide groove 6 and the first slide rod 7 have square cross-sections, they cooperate to form a circumferential limit on the first slide rod 7, effectively preventing the first slide rod 7 from rotating, shifting, or wobbling circumferentially within the first slide groove 6. This ensures that the first slide rod 7 can only make stable linear reciprocating motion along the extension direction of the first slide groove 6. The third slide groove 24 has an arc-shaped structure, and the center of the arc-shaped third slide groove 24 coincides with the center of the rotation axis of the first support arm 2, so that the arc trajectory of the third slide groove 24 is aligned with the first support arm 2. The rotation trajectory remains consistent. Through the cooperation of the third slide groove 24 and the third slide rod 25 located inside it, the rotation range of the first support arm 2 can be effectively limited, the rotation angle of the first support arm 2 can be constrained, and the stability and safety of the movement between the notebook 1 and the first support arm 2 can be guaranteed. The cross-section of the movable frame 15 is a parallelogram structure. Since the movable frame 15 adopts a parallelogram cross-section shape, when the user applies axial pressure to the movable sleeve 12, the movable sleeve 12 will exert a squeezing effect on the movable frame 15 through the inclined block 16, converting the axial movement of the movable sleeve 12 into the radial movement of the movable frame 15, realizing a reasonable conversion of the movement direction.

[0025] Furthermore, the top of the locking block 18 is provided with a first chamfer 29, which is located on both sides of the top of the locking block 18. By providing the first chamfer 29 on both sides of the top of the locking block 18, it can play a guiding role when the locking block 18 and the slot 19 are engaged, effectively reducing the difficulty of alignment between the locking block 18 and the slot 19, avoiding rigid interference or jamming between the top edge of the locking block 18 and the inner wall of the slot 19, so that the locking block 18 can slide into the slot 19 more smoothly and accurately to achieve engagement, improving assembly efficiency and engagement stability. The outer end of the insertion rod 22 away from the second slide rod 21 is provided with a second chamfer 30. The second chamfer 30 can form a guiding structure when the insertion rod 22 and the slot 23 are engaged, making it easier for the insertion rod 22 to be smoothly inserted into the slot 23, reducing frictional resistance and alignment deviation during the insertion process, preventing the end of the insertion rod 22 from colliding or jamming with the opening of the slot 23, and making the engagement between the insertion rod 22 and the slot 23 more precise and reliable.

[0026] The usage steps of this invention are as follows: When using this BIM-based collaborative design system for prefabricated interior decoration, the system defaults to a storage mode: the first support arm 2 and the second support arm 4 are folded and stored on both sides of the laptop 1, and the clamping rod 8 is stored flat on the back of the laptop 1. It can be bent into an arc shape as a handle for easy carrying on-site. When a desktop stand mode is needed: press the movable sleeve 12 to move it axially along the fixed sleeve 3. The inclined block 16 pushes the movable frame 15 radially, causing the locking block 18 to disengage from the slot 19, releasing the angle lock of the second support arm 4. After rotating the second support arm 4 downwards to a suitable angle, release the movable sleeve 12. Under the action of the spring 27, the movable sleeve 12 automatically resets, and the locking block 18 re-engages into the slot 19 for positioning. At this time, the second support arm 4 and the clamping rod 8 together form a desktop support foot, supporting the laptop 1 at a comfortable operating angle, meeting the needs of temporary desktop viewing and editing of BIM models on-site. When a chest-back carrying mode is needed... When the movable sleeve 12 is pressed again, the movable frame 15 drives the second slide rod 21 and the insertion rod 22 to move axially through the inclined second slide groove 20, so that the insertion rod 22 is separated from the slot 23, releasing the rotation lock of the first support arm 2, unfolding the first support arm 2 and the second support arm 4 to form a double-shoulder carrying structure, pulling the tension rod 8 to bend it and fit against the back of the user's neck, maintaining tension and fit under the action of the tension spring 26, the silicone sleeve 9 provides cushioning and anti-slip, and the laptop 1 is stably placed in front of the chest, realizing hands-free operation while walking, which is convenient for on-site verification of the dimensions of prefabricated components and viewing the BIM model. During the operation, the micro laser ranging module 11 on the side of the laptop 1 can be used to measure components such as wall panels, ground, and internal and external corners with one click. The laser ranging data is transmitted to the BIM collaboration software in real time, automatically matching and updating the corresponding component's length, height, flatness and other parameters, realizing digital collaboration from on-site measurement to BIM model update and then to prefabricated component data synchronization.
