Description

Technical Field

[0001] This utility model belongs to the field of deformation monitoring technology, specifically a deformation monitoring device based on the combined operation of manual and GNSS automated monitoring. Background Technology

[0002] Deformation monitoring technology is a key technology for ensuring engineering safety, monitoring and preventing geological disasters, and maintaining infrastructure. Currently, commonly used deformation monitoring methods can be divided into traditional manual deformation monitoring and GNSS (Global Navigation Satellite System) automated monitoring methods. However, both methods have their own advantages and limitations, as detailed below:

[0003] Traditional manual deformation monitoring technology has the advantages of high accuracy, controllable process and quality, relatively low equipment cost, high flexibility, and mature theoretical technology. Its disadvantages include low efficiency and poor real-time performance, high labor costs, and limited operational coverage, making it suitable for short-term, high-precision local monitoring. GNSS automated monitoring, on the other hand, offers the advantages of all-weather, real-time continuous monitoring, a wide operational range, and long-term stable continuous operation. However, its disadvantages include higher investment costs, susceptibility to environmental obstruction and ionospheric effects, relatively lower monitoring accuracy (especially for elevation settlement monitoring), high reliance on algorithms for later-stage results accuracy, and relatively complex equipment installation. It is suitable for long-term, large-scale dynamic monitoring.

[0004] Currently, artificial deformation monitoring and GNSS automated monitoring are carried out separately. When conducting artificial deformation monitoring, a prism needs to be set up separately, and there is no device that can integrate the two monitoring methods. Utility Model Content

[0005] The purpose of this invention is to provide a deformation monitoring device based on the combined operation of manual and GNSS automated monitoring, and also to provide a prism connection device and method applicable to the combined operation of manual and GNSS automated monitoring, thereby overcoming the shortcomings of each.

[0006] The technical solution adopted in this utility model is: a deformation monitoring device based on the joint operation of manual and GNSS automated monitoring, including a GNSS receiver, a prism, and a connecting frame; the connecting frame is a hollow and closed frame structure with a top connector at its top, and the bottom of the GNSS receiver has a connecting hole, the top connector being detachably installed in the connecting hole of the GNSS receiver; the bottom end of the connecting frame is integrally provided with a connecting part, the connecting part being rotatably connected to the monitoring point connector at the monitoring point through a horizontal rotating structure around a vertical axis; the prism is rotatably installed at the center of the connecting frame through a vertical rotating component around a horizontal axis; the vertical central axis of the monitoring point connector, the vertical central axis of the connecting frame, the center of the prism, and the phase center of the GNSS receiver are located on the same vertical line.

[0007] Furthermore, the horizontal rotating structure includes a buckle, a vertically arranged insertion hole in the connecting part, and a horizontally arranged limiting hole in the connecting part;

[0008] The buckle is L-shaped and includes two segments, one perpendicular to each other. The first segment is disposed in the limiting hole, and its two ends slide in contact with the inner wall of the limiting hole along the longitudinal direction. The second segment is fixed to the first segment at one end along the transverse direction, and the other end extends outward to the connecting part. A telescopic spring is fixed on the left side of the first segment along the transverse direction, and the left end of the telescopic spring is fixed to the left side wall of the limiting hole. A limiting protrusion is provided on the right side where it aligns with the insertion hole.

[0009] Furthermore, the outer periphery of the monitoring point connector is provided with a concave groove; the groove is adapted to the limiting protrusion, and after the monitoring point connector is inserted into the insertion hole, the limiting protrusion is inserted into the groove to limit the monitoring point connector.

[0010] Furthermore, the vertical rotating component includes connecting shafts fixed laterally to both ends of the prism, the two connecting shafts being coaxial and rotatably mounted on the connecting frame, and a locking structure for locking the pitch angle of the prism is provided between the connecting shafts and the connecting frame.

[0011] Furthermore, the top connector is threadedly connected to the connection hole of the GNSS receiver.

[0012] Furthermore, the connecting frame is square.

[0013] This utility model has the following beneficial effects: The deformation monitoring device based on the joint operation of manual and GNSS automated monitoring disclosed in this utility model connects the GNSS receiver required for online monitoring, the measuring prism required for manual monitoring, and the monitoring points. It can simultaneously perform GNSS automated monitoring and traditional manual monitoring operations, so that GNSS automated monitoring and traditional manual monitoring can be carried out simultaneously without interfering with each other. By integrating GNSS automated monitoring and traditional manual monitoring technologies, this device can give full play to the advantages of the high accuracy of traditional manual monitoring and the real-time advantage of GNSS automated monitoring. The accuracy of automatic monitoring can be verified and corrected through the results of manual monitoring, thereby greatly improving the accuracy of GNSS automated monitoring results.

[0014] It achieves horizontal rotation and orientation adjustment of the circular prism through the horizontal rotation of the connecting frame, and achieves rotation of the circular prism around the vertical axis through the vertical rotating component, thus allowing for pitch adjustment of the circular prism's orientation. This enables manual monitoring to adjust the circular prism in all directions, adapting to complex terrain and different monitoring angles, improving flexibility and expanding the monitoring coverage. For example, it is suitable for complex scenarios such as steep slopes and bridges.

[0015] By ensuring that the phase centers of the main frame, monitoring point connectors, vertical rotating components, and GNSS receiver are located on the same vertical axis, the consistency of the phase centers during rotation is ensured, error sources are eliminated, and the accuracy of the calibration is improved.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.

Figure 1 The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] Deformation monitoring devices based on a combination of manual and GNSS automated monitoring operations, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a GNSS receiver 6, a circular prism 5, and a connecting frame 1. The connecting frame 1 is a hollow, closed-off frame structure with a top connector 4 at its top. The GNSS receiver 6 has a connecting hole at its bottom, and the top connector 4 can be detachably installed into the connecting hole of the GNSS receiver 6. A connecting part 2 is integrally formed at the bottom of the connecting frame 1, meaning that the connecting part 2 and the connecting frame 1 are a single unit. The connecting part 2 is rotatably connected to a monitoring point connector 7 at a monitoring point via a horizontal rotation structure around a vertical axis. That is, the connecting part 2 is connected to the monitoring point connector 7, and the connecting part 2 and the monitoring point connector 7 can rotate around a vertical axis, thereby allowing the connecting frame 1 to drive the GNSS receiver 6 and the circular prism 5 to rotate horizontally together. This vertical axis coincides with the vertical central axis of the connecting frame 1 and also with the vertical central axis of the monitoring point connector 7. The circular prism 5 is rotatably mounted in the hollow area of ​​the connecting frame 1 via the vertical rotating component 3 around a horizontal axis. This horizontal axis is the horizontal central axis of the circular prism 5, meaning that the circular prism 5 can rotate around the horizontal central axis, ensuring that its center remains unchanged during rotation.

[0028] The GNSS receiver 6 of this invention consists of two parts: an antenna and a receiver. The antenna is responsible for receiving signals from satellites, while the receiver is responsible for interpreting these signals. The antenna and receiver are integrated into a single unit. The phase center of the GNSS receiver 6 is the phase center of the antenna of the GNSS receiver 6. In this embodiment, the GNSS receiver 6 has a regular symmetrical structure, and its phase center is located on its central axis.

[0029] This utility model discloses a deformation monitoring device based on the combined operation of manual and GNSS automated monitoring. It connects the GNSS receiver 6 required for online monitoring, the measuring prism 5 required for manual monitoring, and the monitoring points. It can simultaneously perform GNSS automated monitoring and traditional manual monitoring, allowing them to work simultaneously without interfering with each other. By integrating GNSS automated monitoring and traditional manual monitoring technologies, this device can leverage both the high accuracy of traditional manual monitoring and the real-time advantage of GNSS automated monitoring. The accuracy of real-time monitoring can be verified and corrected through manual monitoring results, which can greatly improve the accuracy of GNSS automated monitoring results.

[0030] The circular prism 5 is horizontally rotated and its orientation adjusted by the connecting frame 1 rotating around the vertical axis, and the circular prism 5 is rotated around the horizontal axis by the vertical rotating component 3. This allows for pitch adjustment of the circular prism 5, enabling manual monitoring to adjust it in all directions, adapting to complex terrain and different monitoring angles, improving flexibility and expanding monitoring coverage. This is suitable for complex scenarios such as steep slopes and bridges.

[0031] The monitoring point connector 7 is a rod-shaped component that is fixed to the monitoring position through pre-embedding or a base. The vertical center axis of the monitoring point connector 7, the vertical center axis of the connecting frame 1, the center point of the circular prism 5, and the phase center of the GNSS receiver 6 are located on the same vertical line, ensuring that the phase center of the GNSS receiver 6 and the phase center of the circular prism 5 remain unchanged during rotation, eliminating error sources and improving the accuracy of the calibration.

[0032] The horizontal rotation structure can be a threaded structure, such as: the monitoring point connector 7 is configured as a threaded rod, and the connecting part 2 is configured with a threaded hole, with the two connected by threads. Alternatively, a sleeve connection can be used between the monitoring point connector 7 and the connecting part 2, with a limit screw installed radially to lock their positions. However, the threaded connection will change the height position of the GNSS receiver 6 and the circular prism 5 during adjustment, and the sleeve-type structure with the limit screw is inconvenient to operate. In this embodiment, as shown... Figure 5 , Figure 6 and Figure 7 As shown, the horizontal rotation structure includes a buckle 8, a vertically arranged insertion hole 201 on the connecting part 2, and a horizontally arranged limiting hole 202 on the connecting part 2; the insertion hole 201 is adapted to the monitoring point connector 7 and is used to insert the monitoring point connector 7. Figure 6As shown, the buckle 8 is L-shaped and includes two perpendicular segments, a first segment 801 and a second segment 802. The first segment 801 is disposed in the limiting hole 202, and its two ends slide in longitudinal engagement with the inner wall of the limiting hole 202. The second segment 802 is fixed to the first segment 801 at one end in the transverse direction, and the other end extends outward to the connecting part 2. A telescopic spring 9 is fixed to the left side of the first segment 801 in the transverse direction, and the left end of the telescopic spring 9 is fixed to the left side wall of the limiting hole 202. A limiting protrusion 803 is provided on the right side, aligned with the insertion hole 201.

[0033] like Figure 4 As shown, the outer periphery of the monitoring point connector 7 is provided with a concave groove 701. Figure 5 and Figure 6 As shown, the groove 701 is adapted to the limiting protrusion 803. After the monitoring point connector 7 is inserted into the insertion hole 201, the limiting protrusion 803 is inserted into the groove 701 to limit the monitoring point connector 7.

[0034] After the monitoring point connector 7 is inserted into the insertion hole 201, the limiting protrusion 803 is pushed into the groove 701 under the elastic force of the telescopic spring 9, which limits the connection frame 1 and prevents the connection frame 1 and the monitoring point connector 7 from rotating relative to each other. When it is necessary to rotate and adjust the position, press the second segment 802 of the buckle 8. The first segment 801 compresses the telescopic spring 9, and the limiting protrusion 803 leaves the groove 701 to release the limit. At this time, the connection frame 1 can be rotated. After the connection frame 1 is rotated into place, release the second segment 802, and the limiting protrusion 803 will once again limit the position in the groove 701.

[0035] The implementation of this horizontal rotation structure not only enables rapid installation between the monitoring point connector 7 and the connecting frame 1, but also makes it easier to rotate the connecting frame 1 horizontally.

[0036] The vertical rotating component 3 includes connecting shafts fixed laterally to both ends of the circular prism 5. The two connecting shafts are coaxial and rotatably mounted on the connecting frame 1. A locking structure for locking the pitch angle of the circular prism 5 is provided between the connecting shafts and the connecting frame 1. The locking structure can be a locking screw or a locking nut, etc.

[0037] The top connector 4 is threadedly connected to the connection hole of the GNSS receiver 6. This configuration allows for quick assembly and disassembly of the GNSS receiver, facilitating maintenance and upgrades.

[0038] The connecting frame 1 is square, and the top of the square connecting frame 1 is convenient for installing the top connector 4.

[0039] Although the present invention has been described herein with reference to embodiments thereof, the above embodiments are merely general implementations of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
