Description

Technical Field

[0001] This invention relates to the field of prefabricated buildings, and more particularly to an intelligent building prefabricated node construction auxiliary device. Background Technology

[0002] In recent years, prefabricated buildings have developed rapidly in the construction field due to their high efficiency and environmental protection characteristics, becoming an important force in promoting the modernization of the construction industry. In the construction process of prefabricated buildings, node construction, as the core link connecting various prefabricated components, directly affects the overall stability and safety of the building in terms of its construction quality and efficiency.

[0003] However, in terms of component connection, most of the auxiliary equipment for prefabricated node construction on the market currently relies on multiple bolts to connect steel components. This method is not only cumbersome to install, requiring workers to spend a lot of time and energy on bolt positioning and tightening, resulting in low construction efficiency, but it is also prone to bolt loosening due to external environmental factors such as building vibration, temperature changes, or improper operation during construction. Once the bolts loosen, the connection strength between components weakens, which may lead to structural instability and pose a serious safety risk to the building.

[0004] Furthermore, in large-scale construction projects, the number of construction site nodes is enormous, and existing auxiliary equipment generally lacks effective monitoring methods, making it impossible to detect the status of nodes in real time and accurately. When nodes are deformed or damaged, it is difficult to detect them in time and take repair measures, resulting in long-term safety hazards that may cause unpredictable consequences in later use.

[0005] A search revealed Chinese Patent Publication No. CN118187293B, which discloses a prefabricated building beam-column connection node. The node includes a beam-column connection sleeve and multiple beam-column stiffening ribs. Multiple fixing plates are fixedly installed on the outer side of the beam-column connection sleeve, with two fixing plates forming a group. It also includes a base beam-column and multiple sets of damping components. The advantages are: adjustable and adaptable installation to accommodate building measurement or manufacturing errors within a certain range; improved horizontal and vertical load and bending moment resistance of the connection node after installation; increased prestress in the beams and columns; and buffering and damping vibrations and impacts that the beams and columns may experience during use, reducing stress concentration on the structure and improving wind resistance and stability.

[0006] The aforementioned patent effectively solves the problem that beam-column connection nodes may have certain design errors during the manufacturing process, making them difficult to assemble and unable to be installed in an adjustable manner to address the errors. However, in actual use, the installation of multiple bolt fasteners is time-consuming and labor-intensive. Summary of the Invention

The positioning member is located in the movable opening and one end extends into the annular groove. The annular groove is located on the side of the mounting shell near the limiting plate. The inner sidewall of the annular groove has several toothed grooves. When the movable ring is pushed and moves toward the mounting shell, the positioning member cooperates with the toothed grooves to restrict the rotation of the limiting plate.

[0010] In some embodiments, the limiting mechanism further includes a plurality of connecting rods, which are spaced apart along the outer periphery of the movable ring. One end of each connecting rod is connected to the movable ring via a first rotating shaft, which is parallel to the limiting plate. The number of positioning elements is the same as the number of connecting rods. Each positioning element includes a limiting block and a toothed block. The other end of each connecting rod is connected to the limiting block via a second rotating shaft. The toothed block is fixedly connected to the side of the limiting block away from the movable ring. When the movable ring is pushed to move toward the mounting housing, the connecting rod pushes the limiting block and the toothed block, and the toothed block engages with the toothed groove.

[0011] In some embodiments, the inner wall of the movable opening has a groove arranged along the direction in which the limiting block is pushed, and a slider is fixedly connected to the limiting block, the slider being embedded in the groove.

[0012] In some embodiments, when the internal threaded ring rotates in the first direction, the internal threaded ring moves toward the mounting housing.

[0013] In some embodiments, the intelligent building prefabricated node construction auxiliary equipment further includes a plurality of alarm mechanisms, the number of which is the same as the number of connecting pipes.

[0015] In some embodiments, the intelligent building prefabricated node construction auxiliary equipment further includes a rotating disk, which is tractively connected to the first end of the active rod so that the active rod rotates together when the rotating disk rotates.

[0016] In some embodiments, the rotating disk is detachably connected to the drive rod.

[0017] In some embodiments, each driven rod is fixedly fitted with two spaced limiting rings, one of which is located inside the mounting housing and contacts the inner wall of the mounting housing, and the other is located inside the connecting tube and contacts the end face of the fixed column.

Figure 10 for Figure 1 The diagram shows a three-dimensional structure of a circular tube in an auxiliary device for constructing prefabricated nodes in intelligent buildings. Figure 11 for Figure 1 The diagram shows the location distribution of pressure sensors in the intelligent building prefabricated node construction auxiliary equipment. This invention discloses an intelligent building prefabricated node construction auxiliary equipment, which can be used to construct nodes in prefabricated buildings that require connecting components in at least two directions, such as beam-column nodes, which require connecting vertical columns and horizontal beams, or connecting horizontal beams and vertical beams.

[0038] In one embodiment, the intelligent building prefabricated node construction auxiliary equipment includes a mounting shell 1, fixed columns 2, connecting pipes 7, and a transmission mechanism; several fixed columns 2 are fixedly connected to different sides of the mounting shell 1, and several connecting pipes 7 are fitted onto several fixed columns 2; the transmission mechanism includes a driving rod 11 and several driven rods 4, the driving rod 11 passing through one side of the mounting shell 1 such that the first end of the driving rod 11 is located outside the mounting shell 1, and the second end is located inside the mounting shell 1, and the second end of the driving rod 11 is fixedly connected to a driving gear 10; the driven rods... The number of driven rods 4 is the same as the number of fixed posts 2. Several driven rods 4 pass through the side of the fixed posts 2 and the mounting shell 1 so that the first end of each driven rod 4 is located inside the mounting shell 1 and the second end is located outside the fixed post 2. The first end of each driven rod 4 is fixedly connected to a driven gear 3. Each driven gear 3 meshes with the driving gear 10. The second end of each driven rod 4 is fixedly connected to a screw 6. Each connecting tube 7 is fixedly installed with a screw hole 9 that mates with the screw 6. When the driving rod 11 rotates in the first direction, the connecting tubes 7 all move in the direction of the mounting shell 1.

[0039] In this embodiment, the mounting shell 1 is a square hollow shell. The number of fixing posts 2 can be four, each fixedly connected to one of the four sides of the mounting shell 1. These four sides are four surfaces that can be closed end-to-end, such as the upper side, right side, lower side, and left side of the mounting shell 1. The fixing posts 2 are rectangular cross-section posts, and the cross-sectional shape of the connecting pipe 7 matches the cross-sectional shape of the fixing posts 2, i.e., it is a rectangular connecting pipe 7. The driving rod 11 can be a rod with a circular cross-section. The driving rod 11 passes through the front side of the mounting shell 1 and is perpendicular to the front side of the mounting shell 1. The driving rod 11 can rotate around its axis. The driving gear 10 is located inside the mounting shell 1. The driving gear 10 is a bevel gear 10, fixed to the second end of the driving rod 11. When the driving rod 11 rotates, it drives the driving gear 10 to rotate in the same direction. The driven rod 4 can be a rod with a circular cross-section. Four driven rods 4 pass through the four fixed posts 2 and the four sides of the mounting shell 1, with the first end of each driven rod 4 located inside the mounting shell 1. All four driven rods 4 are perpendicular to the driving rod 11. The driven gear 3 is a bevel-shaped driven gear 3, fixed to the first end of the driven rod 4. All four driven gears 3 mesh with the driving gear 10. The four driven gears 3 are parallel to the upper, right, lower, and left sides of the mounting shell 1, respectively. The driving gear 10 is parallel to the rear side of the mounting shell 1. When the driving gear 10 rotates, the four driven gears 3 are also driven to rotate, thereby causing the four driven rods 4 to rotate around their respective axes. The second end of the driven rod 4, i.e., the end furthest from the mounting shell 1, is fixedly connected to a screw 6 whose axis is on the same straight line. That is, when the driven rod 4 rotates, the four screws 6 also rotate synchronously. While the connecting pipe 7 is sleeved on the fixed post 2, its internal screw hole 9 and screw rod 6 form a threaded engagement. Since the cross-sectional shape of the connecting pipe 7 is compatible with the cross-sectional shape and size of the fixed post 2, when the screw rod 6 rotates, the connecting pipe 7 is restricted from rotating by the fixed post 2 and will make a translational movement along the axial direction of the screw rod 6. By pre-setting the thread direction of each screw rod 6 and screw hole 9, when the four screw rods 6 rotate, all four connecting pipes 7 will make a translational movement in the direction of the mounting shell 1 until the end of the connecting pipe 7 contacts the side of the mounting shell 1 to complete the connection between the connecting pipe 7 and the mounting shell 1.

[0040] The driving rod 11, driving gear 10, driven rod 4, driven gear 3 and screw 6 provided in this embodiment of the invention are all made of stainless steel, which has the advantages of corrosion resistance and high hardness, thus avoiding rusting during long-term use.

[0041] Specifically, a connecting block 8 is fixedly connected to the inner wall of the connecting pipe 7, and the aforementioned screw hole 9 is opened in the connecting block 8. The axis of the screw hole 9 extends along the length direction of the connecting pipe 7 and is on the same straight line as the axis of the screw 6.

[0042] In one embodiment, the intelligent building prefabricated node construction auxiliary equipment further includes a rotating disk 14, which is connected to the first end of the active rod 11 so that the rotating disk 14 drives the active rod 11 to rotate together when it rotates.

[0043] In this embodiment, the axis of the rotating disk 14 is on the same axis as the axis of the active rod 11. The diameter of the rotating disk 14 is larger than the diameter of the active rod 11, and the rotating disk 14 is spaced apart from the side of the mounting shell 1. Compared with directly rotating the active rod 11, rotating the rotating disk 14 is more convenient for applying force.

[0044] In one embodiment, the rotating disk 14 is detachably connected to the active rod 11 and is connected when a node needs to be installed. In this way, one rotating disk 14 can be used to install multiple nodes, which can save resources on the one hand, and on the other hand, the rotating disk 14 can be removed after the node is installed to save space.

[0045] In this embodiment, a polygonal hole 12, specifically a hexagonal hole, is provided at the first end of the active rod 11. A polygonal rod 13, specifically a hexagonal rod, is fixedly connected to the side of the rotating disk 14 near the mounting shell 1. The specific shape and size of the polygonal rod 13 are adapted to the shape and size of the polygonal hole 12. Thus, the polygonal rod 13 can be inserted into the polygonal hole 12. By rotating the rotating disk 14, the active rod 11 can be driven to rotate, thereby completing the transmission connection between the rotating disk 14 and the active rod 11. It is convenient and quick to use. Furthermore, after installation, the polygonal rod 13 can be pulled out from the polygonal hole 12.

[0046] In one embodiment, each driven rod 4 is fixedly fitted with two spaced limiting rings 5, one of which is located inside the mounting shell 1 and contacts the inner wall of the mounting shell 1, and the other is located inside the connecting pipe 7 and contacts the end face of the fixed column 2.

[0047] In this embodiment, when the screw 6 rotates to drive the connecting pipe 7 to translate towards the mounting shell 1, the connecting block 8 inside the connecting pipe 7 will generate a pushing force on the driven rod 4; when the screw 6 rotates to drive the connecting pipe 7 to translate away from the mounting shell 1 (when disassembling the connecting pipe 7), the connecting block 8 inside the connecting pipe 7 will generate a pulling force on the driven rod 4. By setting two limiting rings 5 ​​fixedly connected to the driven rod 4, the driven rod 4 is fixed in its axial position, thereby preventing displacement of the driven rod 4 during use and improving safety.

[0048] Specifically, when the driven rod 4 tends to be pulled, the limiting ring 5, which contacts the inner wall of the mounting housing 1, can prevent the driven rod 4 from being pulled. When the driven rod 4 tends to be pushed, the limiting ring 5, which contacts the end face of the fixed column 2, can prevent the driven rod 4 from being pushed.

[0049] In one embodiment, the intelligent building prefabricated node construction auxiliary equipment further includes a limiting mechanism, which includes a limiting plate 15, an external threaded tube 16, an internal threaded ring 26, a movable ring 17, several positioning components, and an annular groove 24. The limiting plate 15 is disposed opposite to the mounting shell 1 and fixedly connected to the active rod 11. One end of the external threaded tube 16 is fixedly connected to the side of the limiting plate 15 away from the mounting shell 1. The internal threaded ring 26 forms a threaded engagement with the external threaded tube 16 and can move axially along the external threaded tube 16. The movable ring 17 is slidably embedded in the external threaded tube 16 and... Located between the limiting plate 15 and the internal threaded ring 26, the positioning member can push the movable ring 17 when the internal threaded ring 26 moves toward the mounting shell 1. The positioning member is connected to the movable ring 17. The limiting plate 15 has a movable opening 23. The positioning member is located in the movable opening 23 and one end extends into the annular groove 24. The annular groove 24 is located on the side of the mounting shell 1 near the limiting plate 15. Several toothed grooves 25 are provided on the inner side wall of the annular groove 24. When the movable ring 17 is pushed and moves toward the mounting shell 1, the positioning member cooperates with the toothed grooves 25 to restrict the rotation of the limiting plate 15.

[0050] In this embodiment, the limiting plate 15 is a circular plate, which is disposed opposite to the front side of the mounting shell 1 and sleeved on the first end of the active rod 11. The end face of the first end of the active rod 11 can be flush with the side of the limiting plate 15 away from the mounting shell 1, so as to expose the polygonal hole 12 on the first end of the active rod 11, which facilitates the insertion of the polygonal rod 13 connected to the rotating disk 14. Since the active rod 11 is fixedly connected to the limiting plate 15, when the active rod 11 rotates, it also drives the limiting plate 15 to rotate together. One end of the external threaded tube 16 is fixedly connected to the side of the limiting plate 15 away from the mounting shell 1, and can be arranged on the same axis as the active rod 11. In this way, when it is necessary to insert the polygonal rod 13 into the polygonal hole 12, it can be inserted from the middle of the external threaded tube 16. An internal threaded ring 26 is fitted onto an external threaded tube 16, and the threads on the inner wall of the internal threaded ring 26 engage with the threads on the outer wall of the external threaded tube 16. By rotating the internal threaded ring 26, the internal threaded ring 26 can move axially along the external threaded tube 16. For example, when the internal threaded ring 26 rotates in a certain direction, it moves along the axis of the external threaded tube 16 towards the mounting housing 1, i.e., towards the limiting plate 15. A movable ring 17 is embedded in the external threaded tube 16 and located between the limiting plate 15 and the internal threaded ring 26. Specifically, the external threaded tube 16 has an elongated insertion hole, and the inner wall of the movable ring 17 has an insert that engages with the insertion hole. The length of the insert is less than the length of the insertion hole, so as to achieve relative sliding between the movable ring 17 and the external threaded tube 16. When the internal threaded ring 26 moves toward the mounting shell 1, it pushes the movable ring 17 toward the mounting shell 1. The sliding ring drives the positioning element to move, so that the positioning element is inserted into the toothed groove 25 in the annular groove 24, thereby fixing the limiting plate 15 and the active rod 11, so that they will not rotate due to vibration after the connecting pipe 7 is fixed, thus avoiding the phenomenon of loosening between the connecting pipe 7 and the mounting shell 1.

[0051] Specifically, four positioning elements can be provided, and four movable openings 23 are also provided, corresponding to the positioning elements. The four positioning elements can be evenly spaced along the circumference of the sliding ring. The four positioning elements mesh with different toothed grooves 25 in the annular groove 24 to enhance the stability of fixing the limiting plate 15. When it is necessary to disassemble the connecting pipe 7, the internal threaded ring 26 can be rotated away from the sliding ring, and the sliding ring can be pulled to release the meshing of the positioning elements with the toothed grooves 25. A handle 27 can be fixedly connected to the outer peripheral wall of the internal threaded ring 26. The handle 27 is an L-shaped handle. By applying force to the handle 27, it is convenient to rotate the internal threaded ring 26. Specifically, four handles 27 can be provided, evenly spaced along the outer peripheral wall of the internal threaded ring 26.

[0052] In one embodiment, when the internal threaded ring 26 rotates in the first direction, the internal threaded ring 26 moves toward the mounting housing 1.

[0053] In this embodiment, the directions of the threads on the internal threaded ring 26 and the external threaded tube 16 can be preset so that when the internal threaded ring 26 rotates in the first direction, it moves towards the mounting shell 1. That is, when fixing the connecting tube 7, the driving rod 11 rotates in the first direction (e.g., clockwise), and when further fixing the limiting plate 15 and the driving rod 11, the internal threaded ring 26 also rotates in the same direction (e.g., clockwise). This avoids the external threaded tube 16 and the limiting plate 15 from rotating in the second direction (e.g., counterclockwise) when the internal threaded ring 26 is rotated, thereby preventing the driving rod 11 from rotating in the second direction and causing loosening between the connecting tube 7 and the mounting shell 1.

[0054] In one embodiment, the limiting mechanism further includes a plurality of connecting rods 19, which are spaced apart along the outer periphery of the movable ring 17. One end of each connecting rod 19 is connected to the movable ring 17 via a first rotating shaft, which is parallel to the limiting plate 15. The number of positioning elements is the same as the number of connecting rods 19. Each positioning element includes a limiting block 20 and a toothed block 22. The other end of each connecting rod 19 is connected to the limiting block 20 via a second rotating shaft. The toothed block 22 is fixedly connected to the side of the limiting block 20 away from the movable ring 17. When the movable ring 17 is pushed and moves toward the mounting shell 1, the connecting rods 19 push the limiting block 20 and the toothed block 22, and the toothed block 22 engages with the toothed groove 25.

[0055] In this embodiment, there can be four connecting rods 19. Four connecting openings 18 are spaced apart on the outer periphery of the movable ring 17. Each connecting opening 18 has a first rotating shaft, which is parallel to the limiting plate 15. One end of the connecting rod 19 is sleeved on the first rotating shaft. The limiting block 20 is located in the movable opening 23 on the limiting plate 15. Its first end protrudes from the side of the limiting plate 15 away from the mounting shell 1, and its second end protrudes from the side of the limiting plate 15 near the mounting shell 1 and extends into the annular groove 24 on the mounting shell 1. The first end of the limiting block 20 has a connecting ear 21, and a second rotating shaft passes through the connecting ear 21. Each second rotating shaft is parallel to its corresponding first rotating shaft. A toothed block 22 is fixedly connected to the side of the limiting block 20 away from the movable ring 17. The shape and orientation of the toothed block 22 are adapted to the toothed groove 25, and any toothed block 22 can mesh with any toothed groove 25 in the annular groove 24. When the movable ring 17 is pushed and moves towards the mounting shell 1, the four push rods push the four limiting blocks 20 to expand relative to the movable ring 17. This can be understood as follows: before the movable ring 17 is pushed, the four connecting rods 19 and the limiting plate 15 have a certain angle. After the movable ring 17 is pushed, the four connecting rods 19 gradually become parallel to the limiting blocks 20, so that the four toothed blocks 22 mesh with the toothed grooves 25 in four directions, thereby fixing the movable ring 17 and the external threaded tube 16 so that they do not rotate, and further fixing the limiting plate 15 and the driving rod 11 so that they do not rotate.

[0056] In one embodiment, the inner wall of the movable opening 23 has a groove (not marked in the figure) arranged along the direction in which the limiting block 20 is pushed. A slider (not marked in the figure) is fixedly connected to the limiting block 20, and the slider is embedded in the groove. The groove and the slider cooperate to limit the limiting block 20, preventing the limiting block 20 from tilting during movement, thereby ensuring that the toothed block 22 can be accurately inserted into the toothed groove 25.

[0057] In one embodiment, the intelligent building prefabricated node construction auxiliary equipment also includes several alarm mechanisms, the number of which is the same as the number of connecting pipes 7. Each alarm mechanism includes a circular pipe 29, a circular rod 33, a pressure sensor 30, a pull rope 32, and an alarm 36. One end of the circular pipe 29 is detachably connected to the connecting pipe 7. One end of the circular rod 33 extends from the other end of the circular pipe 29 into the circular pipe 29. The other end of the circular rod 33 is fixedly connected to one end of the pressure sensor 30. The other end of the pressure sensor 30 is connected to one end of the pull rope 32. The other end of the pull rope 32 is detachably connected to the limiting plate 15. The alarm 36 is electrically connected to the pressure sensor 30.

[0058] In this embodiment, since one end of the circular tube 29 is detachably connected to the connecting tube 7 and the other end of the pull rope 32 is detachably connected to the limiting plate 15, the alarm mechanism can be installed after the connecting tube 7 is tightened and fixed, thereby avoiding accidental alarm triggering during node installation. When installing the alarm mechanism, one end of the circular tube 29 can be connected to the connecting tube 7 first, and the pressure sensor 30 and the circular rod 33 can be pulled outward by the pull rope 32. The other end of the pull rope 32 can be connected to the limiting plate 15 and the pull rope 32 can be tensioned, but care should be taken not to over-tension the pull rope 32. After the node is installed, when it is subjected to great pressure, causing the limit plate 15 to rotate or the connecting pipe 7 to shift or break, the pull rope 32 will inevitably be pulled. Simultaneously, the pull rope 32 pulls the pressure sensor 30. By changing the tension of the pull rope 32 on the pressure sensor 30, the pressure sensor 30 is triggered to control the alarm 36 to sound an alarm. The alarm 36 can be a buzzer alarm or an audible and visual alarm. At this time, the staff can immediately know which node among many nodes has a problem, effectively improving its safety. By setting up an alarm mechanism with the same number as the connecting pipes 7, such as four sets of alarm mechanisms, with each set of alarm mechanisms connected to a connecting pipe 7 via its pull rope 32, it is possible to more accurately determine which connecting pipe 7 in that node has a problem.

[0059] Specifically, a connecting plate 28 is fixedly installed at one end of the round tube 29 for connecting to the connecting tube 7, and the connecting plate 28 has a connecting hole. Each connecting tube 7 has a connecting rod perpendicular to its wall surface on the side wall near the limiting plate 15. By fitting the connecting plate 28 onto the connecting rod, one end of the round tube 29 is connected to the connecting tube 7. The wall surface of the limiting plate 15 away from the mounting housing 1 has the same number of T-shaped hanging rods perpendicular to the alarm mechanism. A hook is installed at one end of the pull rope 32 for connecting to the limiting plate 15. By hanging the hook on the corresponding T-shaped hanging rod, the tensioned end is connected to the limiting plate 15.

[0060] In one embodiment, the alarm mechanism further includes an adjustment assembly, which includes a strip opening 38, a lead screw 34, and a nut 35. The strip opening 38 is formed on the side wall of the circular tube 29 and extends along the axial direction of the circular tube 29. One end of the lead screw 34 passes through the strip opening 38 and is fixedly connected to the circular rod 33. The other end of the lead screw 34 is located on the outside of the circular tube 29. The nut 35 is installed on the other end of the lead screw 34 and the bottom end of the nut 35 contacts the side wall of the circular tube 29.

[0061] In this embodiment, the adjustment component can be used to adjust the tension of the tension: after the connection between the connecting tube 7 and the mounting shell 1 is completed, and the active rod 11 is fixed by the limiting mechanism, one end of the round tube 29 is sleeved on the connecting rod of the connecting tube 7, and then the nut 35 of the adjustment component is loosened. Then, the pressure sensor 30 and the round rod 33 are pulled outward by the pull rope 32 so that the hanging ring 31 can be hung on the T-shaped rod 37. Then, the pull rope 32 is tightened by pulling the nut 35. Next, the nut 35 is tightened to fix the position of the round rod 33 and the tensioned pull rope 32. It should be noted that the pull rope 32 should not be over-tensioned to avoid accidental triggering of the pressure sensor 30.

[0062] In summary, the intelligent building prefabricated node construction auxiliary equipment provided in this embodiment of the invention has at least the following beneficial effects compared to traditional node connection equipment:

[0063] 1. By cooperating with the mounting shell, driving rod, driving gear, driven gear, driven rod, and screw, the driving rod and driving gear can be rotated by rotating the disc and polygonal rod, so that the four driven rods and screw can rotate simultaneously. This allows the threaded connection between the connecting block inside the connecting pipe and the screw to tighten the four connecting pipes at the same time when the screw rotates, thus achieving the purpose of convenient installation.

[0064] Second, through the mutual cooperation between the limiting plate, external threaded pipe, internal threaded ring, movable ring, annular groove, tooth groove and tooth block, the rotation of the internal threaded ring can drive the movable ring to move towards the mounting shell, thereby simultaneously pushing the limiting block and tooth block to expand, so that the tooth block meshes with the tooth groove, thereby locking the position of the limiting plate, effectively solving the problem of bolts easily loosening during use in traditional equipment;

[0065] Third, through the cooperation between the round tube, pressure sensor, pull rope, round rod and alarm, it is possible to change the tension of the pressure sensor by pulling the pull rope when the limit plate rotates or the connecting tube is displaced or broken, thereby controlling the alarm to issue an alarm message, effectively solving the problem that traditional equipment cannot monitor the status of nodes in real time.

[0066] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
