Description

Technical Field

[0001] This invention belongs to the field of geodesy, specifically a device for determining the height attributes of continuously operating GNSS observation towers. Background Technology

[0002] According to Appendix 1-H GNSS observation pier design drawing of the "Technical Regulations for the Construction of Infrastructure of National Modern Surveying and Mapping Benchmark System", the height of the observation pier of the continuously operating benchmark station is about 3.8 meters. It is necessary to accurately measure the height difference between the GNSS observation pier level point and the forced alignment of the top surface of the GNSS observation pier. At the same time, in order to serve the work of refining the geoid, it is necessary to accurately measure the antenna height of the GNSS observation antenna.

[0003] The traditional method for determining the height attributes of a continuously operating GNSS observation tower is to use trigonometric leveling, leveling, and steel tape measurement. Specifically, the power is cut off and the GNSS observation antenna is disassembled in advance to interrupt the acquisition of GNSS observation data. The determination is then completed using trigonometric leveling, leveling, and steel tape measurement.

[0004] However, the above-mentioned device has some problems in use. After GNSS observation is interrupted, it is necessary to work with other continuously operating GNSS observation stations in the vicinity to calculate and obtain the new coordinates of the interrupted GNSS observation station. Based on the new coordinates obtained, differential signals are re-released to provide terminal location information services. This is time-consuming and labor-intensive. The measurement site for GNSS observation piers is limited, making it difficult to carry out the measurement.

[0005] To address this issue, those skilled in the art have proposed a device for continuously operating GNSS observation pier height attribute measurement to solve the problems raised in the background art. Summary of the Invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention employs a clamp component that fits tightly against the top of a continuously operating GNSS observation pier, integrating the clamp component and the pier into a single operating platform, achieving stability in both horizontal and vertical directions. Secondly, it utilizes a leveling rod hanging component to ensure the verticality of the plumb line without manual support. Through a combination of components such as 304 stainless steel spring clips, 304 stainless steel quick-release heavy-duty rotating figure-eight rings, and leveling rod housings, rapid adjustment of the leveling rod height is achieved. Thirdly, it employs a laser leveling rod support component, integrating spatial (horizontal and vertical) aspects with the clamp component, allowing the laser leveling rod to be mounted on... On the laser level platform, height adjustment and locking are achieved, ensuring that the distance between the two reading directions of the laser level is basically consistent and that readings are taken quickly. Fourth, observation data is digitized and observation data photos are stored in categories, facilitating data quality inspection and data organization. Furthermore, the scale box can be customized according to the specific model of the supporting scale to achieve matching between the scale box and the scale, making it easy to adapt to more models of measuring scales. Furthermore, depending on the actual application, the screw can be replaced with a strong magnetic iron disc strip for convenient and quick adjustment of the laser level's height. The device has a simple structure and is easier to assemble.

[0023] This invention's device does not interrupt GNSS observations during measurement, reducing the data processing work required after GNSS observations are interrupted. The height attribute values ​​of the observation pier top surface and GNSS antenna phase center measured by this method can reach an accuracy of 1mm. Using this device can save labor efficiency, requiring only 2 to 3 people to operate. Compared with traditional methods such as trigonometric leveling and leveling, it saves about 50% of human resources. In practice, the height attribute measurement of one continuously operating GNSS observation pier can be completed in 35 minutes, improving efficiency by more than 100%. Using this device in conjunction with a customized program, it can "intelligently guide" the acquisition of observation data, "intelligently record" observation data, "intelligently process" data, and "intelligently manage" data, enabling real-time quality assessment of measurement data on-site after observation is completed and results are obtained.

[0037] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0038] Reference Figures 1-11 This invention provides a device for continuously operating GNSS observation tower height attribute determination, comprising:

[0039] Clamp component 1 is installed on the outer circumference of the GNSS observation pier near the top.

[0040] The scale hanging component 2 is installed on one side of the top outer wall of the clamp component 1. The scale hanging component 2 is T-shaped and is used to fix the measuring scale. A steel ruler is attached to one side of the outer wall of the measuring scale near the top with double-sided adhesive. The bottom end of the steel ruler is attached to the division position of the 2m scale line on the surface of the measuring scale. The reading of the steel ruler is used instead of the reading of the measuring scale.

[0041] Laser level support component 3 is installed on one side of the top outer wall of clamp component 1;

[0042] Auxiliary ruler component 4 is installed on the top surface of the GNSS observation pier near the antenna connecting rod during forced centering.

[0043] The program customization device consists of a data acquisition mobile app developed based on the Android system and a data processing PC developed based on the Windows 7 and above system.

[0044] Specifically, the clamp component 1 includes two arc-shaped steel plates 5, which are symmetrically installed on both sides of the outer circumference of the GNSS observation pier. Each end of the two arc-shaped steel plates 5 is connected to a screw rod 8, and each end of the screw rod 8 is fitted with a screw sleeve. Six iron boxes 6 are evenly distributed on the inner side of the two arc-shaped steel plates 5. The iron boxes 6 are equipped with two thickened rubber shock-absorbing pads. The iron boxes 6 divide the interior of the two arc-shaped steel plates 5 into six equal parts. A steel bar 7 for hanging the top of the observation pier is fixed at the middle position of one side of the outer wall of the two arc-shaped steel plates 5. One end of the steel bar 7 for hanging the top of the observation pier is attached to the top of the GNSS observation pier.

[0045] As can be seen from the above, the contact surface and friction between the clamp component 1 and the vertical surface of the GNSS observation pier of the base station are increased by the iron box 6 and the thickened rubber anti-vibration pad. The thickened rubber anti-vibration pad can be replaced according to the degree of wear. The steel bar 7 on the top of the observation pier is hung on the top of the GNSS observation pier of the base station to prevent the clamp component 1 from sliding up and down.

[0046] Specifically, the ruler hanging component 2 includes a clamp stabilizer 9, a square steel pipe 10, a square steel pipe 23, a ruler hanging tool 11, a 304 spring buckle 12, a 304 fast heavy-duty rotating figure-eight ring 13, and a ruler sleeve box 14.

[0047] Specifically, the clamp component stabilizer 9 includes steel plate 15, steel plate 26, steel plate 37, steel plate 48, and square steel pipe 29. Steel plate 15 has dimensions of 100mm width × 105mm length × 5mm thickness, with a radius of 280mm (arc-shaped steel plate). Steel plate 26 has dimensions of 100mm width × 105mm length × 5mm thickness, with a radius of 275mm (arc-shaped steel plate). Steel plate 37 is a circle with a thickness of 5mm and a radius of 50.76mm, divided by a chord length of 71.3mm, retaining the larger area. A 25mm × 25mm slot is cut along the parallel chord length arc edge. Steel plate 418 has dimensions of 5mm thickness × 50.76mm radius, divided by a chord length of 5... Divide the tube into sections of 0.05mm, retaining the larger area. Create a 25mm x 25mm groove on the parallel chord-length arc edge. Weld and fix square steel pipe 219 to the inner walls of groove 1 and groove 2. Insert square steel pipe 10 into the top inner wall of square steel pipe 219. Sleeve square steel pipe 423 onto the outer wall of square steel pipe 10. Square steel pipe 10 measures 24.5mm x 24.5mm and is 1300mm long. Drill holes in square steel pipe 10 at 100mm intervals, with a hole diameter of 5mm. Square steel pipe 423 measures 25mm x 25mm and is 200mm long. Drill two holes at both ends of square steel pipe 423 at 100mm intervals, with a hole diameter of 5mm.

[0048] As can be seen from the above, the clamp component stabilizer 9 is fixed by a plug, and its function is to provide horizontal and height stability support for the measuring scale.

[0049] Specifically, the measuring tool 11 includes a 25mm×25mm square steel pipe 20, the length of which is 450mm. The square steel pipe 20 is welded to the middle of a square steel pipe 23. The square steel pipe 23 is vertically installed on the top outer wall of the square steel pipe 10. Five steel bars 21 are welded at equal intervals on the top outer wall of the square steel pipe 20. The diameter of the steel bars 21 is 10mm and the length is 50mm. The interval between adjacent steel bars 21 is 80mm. A steel bar ring 22 with a diameter of 3mm is welded to one side of the outer wall of the square steel pipe 20 near the bottom of the steel bar 21.

[0050] Specifically, both ends of the 304 high-speed heavy-duty rotating figure-eight ring 13 are attached with 304 spring buckles 12. The upper 304 spring buckle 12 is attached to the inner wall of the steel ring 22. The scale box 14 includes a stainless steel block 24 with dimensions of 40mm wide × 80mm long × 120mm high. A second ring 26 is installed on the surface of the stainless steel block 24. The second ring 26 is attached to the inner wall of the lower 304 spring buckle 12. The bottom of the stainless steel block 24 has a 40mm wide × 80mm long slot for easy insertion of the measuring scale. The outer walls on both sides of the stainless steel block 24 are fitted with snap-fit ​​screw fasteners 25 near the bottom. One end of each snap-fit ​​screw fastener 25 is attached to the outer walls on both sides of the measuring scale near the top.

[0051] As can be seen from the above, the 304 fast heavy-duty rotating figure-eight ring 13 can achieve stable 360° rotation of the measuring scale without horizontal or vertical displacement, facilitating data measurement in suitable orientations.

[0052] Specifically, the laser level support component 3 includes a clamp component stabilizer 27, a T-shaped laser level support 28, and a screw 29. The clamp component stabilizer 27 is welded together from steel plates 5 30, 6 31, 7 32, 8 33, and 9 34. Steel plate 5 30 has dimensions of 100mm width × 105mm length × 5mm thickness and a radius of 275mm. Steel plate 6 31 has dimensions of 100mm width × 105mm length × 5mm thickness and a radius of 280mm. Steel plate 7 32 is a circle with a thickness of 5mm and a radius of 50.76mm, divided by parallel chord lengths of 60mm and 100mm. Steel plate 732 is vertically welded to the bottom of steel plate 631. Steel plate 833 is a circle with a thickness of 5mm and a radius of 50.76mm, divided into parallel sections with chord lengths of 60mm and 95.73mm. Steel plate 833 is vertically welded to the top of steel plate 631 and steel plate 530. Steel plate 934 is 60mm wide, 100mm long, and 5mm thick. Steel plate 934 is vertically welded to steel plate 732 and steel plate 833. T-shaped laser level support 28 is an iron block with dimensions of 100mm long, 50mm wide, and 5mm thick, used to support the laser level. Screw 229 is installed between clamp component stabilizer 227 and T-shaped laser level support 28.

[0053] Specifically, the auxiliary small ruler component 4 includes a stainless steel nut 35 and a small steel ruler 36. The small steel ruler 36 is attached to the outer wall of one side of the stainless steel nut 35 with double-sided adhesive. The stainless steel nut 35 includes three types of hexagonal nuts. The inner and outer hexagonal dimensions of the three hexagonal nuts are 11mm inner radius × 18.48mm outer hexagonal side length × 30mm height, 11mm inner radius × 18.48mm outer hexagonal side length × 50mm height, and 11mm inner radius × 18.48mm outer hexagonal side length × 60mm inner radius. The graduation line of the small steel ruler 36 is 0.5mm. The small steel ruler 36 is cut into three pieces: 0-35mm, 0-55mm, and 0-75mm to ensure that the zero point and reading of the small steel ruler 36 are clear.

[0054] Specifically, a mobile app for data acquisition was developed based on the Android system, supporting continuous field measurement data acquisition and quality inspection of the height of the observation pier at the reference station and the phase center antenna height of the receiver antenna; on the PC side for data processing, a desktop data standardization processing module was developed based on the Windows system, supporting automated batch processing of field data and photos.

[0055] When using it, follow these steps: First step: Install clamp component 1. Clamp component 1 consists of two arc-shaped steel plates 5, six iron boxes 6 welded evenly to the inner arc, a steel bar 7 for hanging on the top of the GNSS observation pier, and a screw 8 for locking the arc-shaped steel plates 5. When working, first remove the antenna cover on the top of the GNSS observation pier. Then, one person carries clamp component 1 (not tightened) and hangs it on the top of the GNSS observation pier from top to bottom. Use an electric wrench to tighten the two arc-shaped steel plates 5 of clamp component 1, ensuring that the thickened rubber shock-absorbing pads inside clamp component 1 are tightly fitted to the outer surface of the GNSS observation pier, and there is no looseness.

[0056] Step 2: Install the clamp stabilizer 9 of the hanging scale component 2. Insert the clamp stabilizer 9 of the hanging scale component 2 directly into the steel plate of the clamp component 1 using the gap between the insertion points. Insert the 1300mm long square steel pipe 10 directly into the square steel pipe 19 of the clamp stabilizer 9. Adjust the height and insert the pins to prevent vertical movement according to the hole diameter. Place the hanging scale tool 11 at the top of the square steel pipe 23. Use a steel ruler with 0.5mm graduations (e.g., 1000mm) and attach it tightly to the measuring scale with double-sided tape. Ensure that the zero point of the steel ruler is consistent with the 2000mm position of the measuring scale. The top of the measuring scale extends into the inside of the scale housing 14 and is fixed by the fasteners 25 on both sides. It is connected to the ring of the scale housing 14 by the 304 spring buckle 12. The measuring scale is hung vertically by the weight of the measuring scale itself.

[0057] Third step: Install the laser level platform component 3. First, install the clamp stabilizer 27, T-shaped laser level platform 28, and screw 29 of the laser level platform component 3 into a whole. Then, adjust screw 29 so that the distance between the top of the T-shaped laser level platform 28 and the clamp stabilizer 27 is basically the same as the installation height of the upper edge of the clamp component 1 steel plate from the GNSS observation pier. Using the slot gap of the clamp stabilizer 27, insert it directly into the steel plate of the clamp component 1. Note that the distance from the T-shaped laser level platform to the measuring scale is basically the same as the distance to the antenna connecting rod.

[0058] Step 4: Install the auxiliary ruler component 4. Based on the height of the top of the GNSS observation pier and the bottom of the antenna, select a suitable auxiliary ruler component 4 and place it tightly against the antenna connecting rod. The stainless steel nut 35 provides vertical support for the small steel ruler 36, ensuring that the zero point of the small steel ruler 36 is in contact with the top surface of the forced alignment. Three small steel rulers 36 of different heights are selected based on the height of the connecting rod of the GNSS observation antenna. Through the horizontal line of sight of the laser level, read the values ​​of the small steel ruler 36 (0.5mm division) and the steel ruler (0.5mm division) of the measuring scale. It can transmit the height of the top surface of the forced alignment to the measuring scale.

[0059] Step 5: Set up the laser level, initialize the laser level, then place the laser level on the T-shaped laser level base 28, adjust the height of the laser level to ensure that the laser line of sight is horizontal, and that the readings can be clearly read on the measuring scale and the auxiliary small ruler component 4.

[0060] Step 6: Open the mobile app, ① Enter the standard configuration for GNSS observation pier elevation attribute determination, such as instrument model, instrument number, scale number, imaging quality, observer, recorder, checker, etc.; ② Establish the base station information, such as base station name and base station number; ③ Select the base station and enter the observation date, weather, temperature, etc.; ④ Start the observation. The observation sequence is as follows: Readings on auxiliary ruler component 4 (observe once at 120° intervals around the connecting rod and record the distance between auxiliary ruler component 4 and the connecting rod) – Combining the readings of auxiliary ruler component 4, read the steel ruler reading on the measuring rod (add 2000mm to the steel ruler reading) – Raise the line of sight of the laser to the bottom of the antenna and read the steel ruler reading (add 2000mm to the steel ruler reading) – Set up the level instrument at a distance of 3m and ensure it is level, then read the measuring rod reading – Remove the measuring rod from the hanging rod component and place it on the top of the leveling point on the GNSS observation pier base platform, ensuring the measuring rod has a plumb line. Use the level instrument that was just set up to read the measuring rod reading. After one round of observation is completed, adjust the number of 304 spring clips 12 above the hanging rod component 2, re-install the measuring rod, reposition the level instrument, and begin a new round of observation according to the aforementioned observation sequence. ⑤ Observation calculation. The results of the two sets of measurements show that the difference between the height of the observation pier and the height of the connecting rod is within 1 mm, which is considered acceptable.

[0061] Step 7: Use the desktop application to organize the data. Based on the observation data and the results recorded by the APP, combined with the calibration parameters of the measuring scale, intelligent data organization and one-click output were achieved.

[0062] Using trigonometric leveling, leveling, and steel tape measurement methods, four people can complete the measurement of one GNSS observation station in one working day, which requires data recalculation and data processing. However, using this device to determine the elevation attributes of continuously operating GNSS observation stations, three people can complete the measurement of two GNSS observation stations in one working day, increasing efficiency by about 2 times and saving 50% on personnel costs.
