Description

Technical Field

[0001] This invention relates to the field of satellite positioning systems, specifically to a real-time fixed calculation data processing system for high-rise buildings based on BeiDou control and measurement. Background Technology

[0002] The core objective of real-time measurement of high-rise buildings is to ensure structural safety, guarantee controllability throughout the entire life cycle, and support closed-loop management of intelligent construction. By integrating BeiDou positioning, lidar, and multi-source sensors, it is possible to track building deformation (such as wind-induced displacement and construction load deformation) in real time, monitor construction accuracy (installation errors of steel components and concrete shrinkage deformation), and provide early warnings of risks exceeding limits.

[0003] Current technologies often employ total stations for manual measurement and static GNSS post-processing. This approach has several disadvantages: it relies on manual, rotating data collection, resulting in data update intervals of several hours and an inability to capture sudden deformations. It also suffers from poor environmental adaptability, with total stations failing in rain and fog, and limited by line-of-sight conditions, often creating blind spots due to tower cranes obstructing the view of high-rise buildings. Furthermore, existing methods using BeiDou control and measurement technology for fixed calculations on high-rise buildings involve directly fixing the BeiDou receiver equipment to the top of the building. This means that during construction, the operation of side tower cranes can obstruct the signal, reducing accuracy. Additionally, conventional solutions lack effective means to verify the calculated building tilt angle data. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a real-time fixed-resolution data processing system for high-rise buildings based on BeiDou control and measurement, thereby solving the problems mentioned in the background. This invention achieves millimeter-level static monitoring and centimeter-level dynamic tracking of high-rise buildings, significantly improving efficiency compared to traditional total stations. It integrates data from BeiDou, laser ranging, and tilt sensors, effectively eliminating single-source errors and enabling higher precision in synchronous control of ultra-high-rise construction. With the help of a mounting bracket, the BeiDou receiver can be moved to the end for rotation and flipped to a position on the top of the floor for easy operation and disassembly, making subsequent maintenance and repair simpler and more convenient. In conjunction with a cleaning component, the BeiDou receiver can also be automatically cleaned periodically.

A motor is screwed onto the surface of the front end plate. A notch is provided at the bottom of the guide sleeve. The top of the fixing plate and the side of the guide sleeve are welded and fixed together by a support frame.

[0007] Furthermore, the lead screw is connected to the output end of the motor, and the end of the lead screw is embedded into the surface of the rear end plate through a bearing. The side of the rear end plate is integrally formed with a support plate, and the end of the support plate is provided with a positioning seat.

[0008] Furthermore, the Beidou receiver includes a multi-frequency array antenna, a vertical rod, and a support rod. The top of the support rod is integrally formed with a docking sleeve, and the bottom of the vertical rod is fitted with a docking bearing. The docking bearing is integrally embedded inside the docking sleeve, and the multi-frequency array antenna is screwed to the top of the vertical rod.

[0009] Furthermore, the surface of the vertical rod is fitted with gears, the side of the support rod is integrally formed with a transmission frame, the top of the transmission frame is welded with a sliding column, the two ends of the sliding column are integrally formed with conical blocks, and the bottom of the transmission frame is welded with a threaded sleeve.

[0010] Furthermore, the sliding block is integrally embedded inside the guide sleeve, and the top of the transmission frame passes through the inside of the notch. The threaded sleeve is fitted on the surface of the lead screw, the bottom of the support rod is flush with the surface of the positioning seat, the length of the lead screw is greater than the length of the guide sleeve, and both ends of the guide sleeve are in an open state.

[0011] Furthermore, the cleaning assembly includes a column, a sliding rod, a limiting rod, and a cleaning plate. A forward protrusion is welded to the top of the guide sleeve, and a rack is provided on the side of the forward protrusion. A column is integrally formed on the top of the forward protrusion. A sliding rod and a limiting rod are welded to the top of the column.

[0016] 1.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Please see Figures 1 to 9This invention provides the following technical solution: a real-time fixed calculation data processing system for high-rise buildings based on BeiDou control and measurement, including a data acquisition and sensing module, a data transmission and communication module, a real-time calculation and intelligent control module, an early warning output module, and a visualization system. The real-time calculation and intelligent control module is equipped with a multi-source data fusion engine, and the early warning output module establishes a hierarchical early warning mechanism. The data acquisition and sensing module includes a BeiDou monitoring terminal and an environmental sensing unit. The BeiDou monitoring terminal includes multiple BeiDou receivers 3. The BeiDou receivers 3 are fixed to the top of the high-rise building to be measured by a mounting bracket 1. A cleaning component 2 is built on the top of one end of the mounting bracket 1, and a cleaning plate 21 is provided on the side of the cleaning component 2. A multi-frequency antenna array 5 is screwed to the top of the BeiDou receiver 3. The cleaning plate 21 is used to fit against the surface of the multi-frequency antenna array 5. A tilt calibration component 4 is installed on the ground below the BeiDou receiver 3. The environmental sensing unit includes an integrated tilt sensor, a laser rangefinder, a thermometer and hygrometer, and a vibration accelerometer. This processing system utilizes the high-density coverage and multi-frequency signal technology of BeiDou satellites, combined with real-time dynamic positioning algorithms, to achieve millimeter-level static monitoring and centimeter-level dynamic tracking of high-rise buildings. Compared with traditional total stations, its efficiency is significantly improved. Relying on dual-frequency anti-interference and 5G / B5G low-latency transmission, it can maintain continuous operation in extreme weather conditions such as typhoons and dense fog. It integrates data from BeiDou, laser ranging, and tilt sensors, and uses Kalman filtering for dynamic weighting to eliminate single-source errors, resulting in higher accuracy in synchronous control of ultra-high-rise construction.

[0031] In use, the Beidou receiver 3 is installed using a mounting frame 1, positioned at the edge of the top of the building to be measured. This ensures the bottom of the Beidou receiver 3 points towards the ground at the bottom of the building. A tilt calibration component 4 is then installed at the corresponding ground position. Subsequently, the motor 10 at one end of the mounting frame 1 can be activated to control the Beidou receiver 3 to move horizontally, changing the position of the multi-frequency array antenna on top of the Beidou receiver 3 and acquiring calculation data from different fixed positions. The receiver can also avoid obstacles such as tower cranes or other temporary obstacles on the side. During subsequent maintenance and repair, the receiver 3 can be moved to the far end of the mounting frame 1 for manual rotation, allowing for easy access to maintenance and repair on the roof of the high-rise building. Combined with the tilt calibration component 4, the tilt data of the high-rise building can be simultaneously acquired using a laser ranging module 37 during the real-time fixed calculation data acquisition and processing. With the cleaning component 2 on the mounting bracket 1, the top multi-frequency array antenna can also be self-cleaned by controlling the Beidou receiver 3 to move closer to the cleaning component 2.

[0032] In this embodiment, the mounting frame 1 includes a fixed plate 6, a lead screw 11, and a guide sleeve 8. A front end plate 9 and a rear end plate 12 are welded to both ends of the fixed plate 6, respectively. A motor 10 is screwed onto the surface of the front end plate 9. A notch 22 is provided at the bottom of the guide sleeve 8. The top of the fixed plate 6 and the side of the guide sleeve 8 are welded and fixed together by a support frame 7. The lead screw 11 is connected to the output end of the motor 10. The end of the lead screw 11 is embedded into the surface of the rear end plate 12 via a bearing. A support plate 13 is integrally formed on the side of the rear end plate 12, and a positioning seat 14 is provided at the end of the support plate 13. The mounting frame 1 supports the Beidou receiver 3 and fixes it to the top edge of the high-rise building to be measured. This allows for the control of the entire Beidou receiver's translational movement, avoiding the problem of tower crane obstruction causing monitoring obstacles. Furthermore, the mounting frame 1 allows the Beidou receiver 3 to be moved to the end for rotation, flipping it to a position on the top floor for easy operation and disassembly, making subsequent maintenance and repair simpler and more convenient.

[0033] Specifically, the fixing plate 6 is installed on the top of the high-rise building to be tested. After starting the motor 10, the motor 10 drives the lead screw 11 to rotate. The lead screw 11, in conjunction with the threaded sleeve 29, can directly control the entire Beidou receiver 3 to move horizontally, thereby changing the position of the Beidou receiver 3 for receiving satellite signals. At the top of the lead screw 11, the guide sleeve 8 provides limiting support for the sliding column 27 on the Beidou receiver 3, ensuring that the Beidou receiver 3 can remain stable after moving to any position. Furthermore, there is a gap between the rear end of the guide sleeve 8 and the rear end plate 12. Therefore, after controlling the entire Beidou receiver 3 to move to the very end, the sliding column 27 will be moved directly out of the tail end area of ​​the guide sleeve 8. At this point, without the restriction of the sliding sleeve, the entire Beidou receiver 3 can be directly pulled to rotate towards the front end, allowing the top multi-frequency antenna array 5 of the Beidou receiver 3 to be moved to the top of the building for operation.

[0034] In this embodiment, the Beidou receiver 3 includes a multi-frequency array antenna, a vertical rod 32, and a support rod 25. A docking sleeve 30 is integrally formed at the top of the support rod 25, and a docking bearing 31 is fitted at the bottom of the vertical rod 32. The docking bearing 31 is entirely embedded inside the docking sleeve 30. The multi-frequency array antenna is screwed to the top of the vertical rod 32. A gear 33 is fitted on the surface of the vertical rod 32. A transmission frame 26 is integrally formed on the side of the support rod 25. A sliding column 27 is welded to the top of the transmission frame 26, and conical blocks 28 are integrally formed at both ends of the sliding column 27. A threaded sleeve 29 is welded to the bottom of the transmission frame 26. The sliding block is integrally embedded inside the guide sleeve 8, and the top of the transmission frame 26 passes through the notch 22. The threaded sleeve 29 is fitted on the surface of the lead screw 11. The bottom of the support rod 25 is flush with the surface of the positioning seat 14. The length of the lead screw 11 is greater than the length of the guide sleeve 8, and both ends of the guide sleeve 8 are open.

[0035] Specifically, the Beidou receiver 3 is supported by the bottom support rod 25 and the transmission frame 26. The transmission frame 26 is powered by the threaded sleeve 29 and the lead screw 11. The sliding column 27 provides a limiting effect, enabling the Beidou receiver 3 to move stably. With the help of the gear 33 and the rack 24 at the top, the vertical rod 32 and the multi-frequency antenna array 5 above can rotate directly. The structure at the bottom of the docking sleeve 30 always maintains a fixed angle. With the help of the rotation effect, the cleaning component 2 can automatically complete the subsequent cleaning process.

[0036] In this embodiment, the cleaning component 2 includes a column 15, a sliding rod 16, a limiting rod 17, and a cleaning plate 21. A forward-convex plate 23 is welded to the top of the guide sleeve 8. A rack 24 is provided on the side of the forward-convex plate 23. The column 15 is integrally formed on the top of the forward-convex plate 23. The sliding rod 16 and the limiting rod 17 are welded to the top of the column 15. A sliding collar 18 is fitted onto the surface of the sliding rod 16 and the limiting rod 17. A spring 19 is also fitted onto the surface of the sliding rod 16. An extension rod 20 is welded to the side of the sliding collar 18. The cleaning plate 21 is installed at the end of the extension rod 20. A sponge is attached to the surface of the cleaning plate 21. The two ends of the spring 19 are welded and fixed to the surfaces of the sliding collar 18 and the column 15, respectively. The gear 33 and the rack 24 are on the same horizontal plane.

[0037] Specifically, when the Beidou receiver 3 moves towards the cleaning assembly 2 controlled by the motor 10, the outer shell of the multi-frequency antenna array 5 will eventually come into direct contact with the cleaning plate 21 in the cleaning assembly 2. At the same time, the gear 33 and rack 24 at the bottom will mesh. As the motor 10 continues to run, the gear 33 will rotate, and the outer shell of the multi-frequency antenna array 5 at the top will also rotate synchronously. This process can use the cleaning plate 21 to scrape and clean the surface of the outer shell of the multi-frequency antenna array 5. During the translation of the Beidou receiver 3, the cleaning plate 21, the extension rod 20, and the sliding collar 18 will also move along the sliding rod 16 and the limiting rod 17. The spring 19 will contract, so that the cleaning plate 21 always maintains a high pressure and is in contact with the surface of the outer shell of the multi-frequency antenna array 5.

[0038] In this embodiment, the tilt calibration component 4 includes a windproof chamber 35, a laser ranging module 37, and a calibration base 38. The top of the calibration base 38 is provided with an inclined plate 40, and one end of the calibration base 38 is provided with a reflector plate 39. A hanging plate 34 is welded to the side of the docking sleeve 30. The windproof chamber 35 is installed at the bottom of the hanging plate 34. A vertical line 36 is connected inside the windproof chamber 35, and the bottom of the vertical line 36 is connected to the laser ranging module 37. An opening is provided at the bottom of the windproof chamber 35. By building the tilt calibration component 4 at the bottom of a high-rise building, and in conjunction with the ranging unit of the Beidou receiver 3 itself, tilt data can be additionally obtained through the ranging module when the high-rise building under test is tilted. This data is used to verify the fixed calculation data obtained by the Beidou receiver 3 itself. Combined with the cleaning component 2, the Beidou receiver 3 can also be automatically cleaned periodically. Specifically, after the Beidou receiver 3 is moved to align with the calibration seat 38 at the bottom, if the entire building under test is not tilted, the laser ranging module 37 at the bottom will directly illuminate the reflector 39 at the bottom, and the collected distance signal will reach its maximum value. When the building tilts, the laser ranging module 37 will be driven to illuminate the wall or the inclined plate 40 vertically downwards, thereby changing the detected distance data. This data is then used to verify the data calculated by the Beidou receiver 3 itself. The laser ranging module 37 is an existing mature technology and is not within the scope of protection of this invention. Therefore, its internal structure, principle, specifications, and other technical contents will not be described in detail here.

[0039] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
