[0029] It also includes a calibration component for measuring the RTK body 2, which is located between the RTK body 2 and the mounting plate 3. First, the RTK body 2 is fixedly mounted on the middle of the mounting plate 3 through the calibration component, and then the aluminum profile bracket 1 is erected on the top of the boundary monument, and the support plate 4 is driven to move along the top surface of the boundary monument to the middle of the boundary monument to center it, and then the aluminum profile bracket 1 is fixed to the boundary monument through the use of the locking piece 6 and the rubber block 7. This method can reduce the RTK body 2 on the top of the boundary monument. When encountering strong winds or other external forces, it will move or be subject to other interferences, causing the instrument to be unstable, thereby causing large errors in measurement accuracy.

[0030] Furthermore, the positions of the support plate 2 5 and the support plate 1 4 are symmetrical to each other, and the midpoints of the support plate 2 5 and the support plate 1 4 are on the same horizontal line as the midpoint of the aluminum profile bracket 1 .

The clamping plate 63 is located at one end of the rotating rod 61 close to the rubber block 7, and the flange 62 is located at one end of the rotating rod 61 away from the clamping plate 63. By rotating the flange 62, the clamping plate 63 on the rotating rod 61 can be driven to rotate until it contacts and locks with the surface of the boundary monument.

[0033] See also Figures 4 to 6The utility model provides a technical solution: further, the calibration component includes a mounting bracket 8 fixedly mounted on the top of the mounting plate 3, a leveling base 9 is provided above the mounting bracket 8, and leveling bolts 10 are threadedly installed at the corners of the mounting bracket 8 and the leveling base 9, and a rotating block 11 is fixedly installed on the outer periphery of multiple leveling bolts 10, a rotating block 12 is rotatably installed on the top of the leveling base 9, a mounting block 13 is clamped and installed on the top of the rotating block 12, a measuring piece 14 is sleeved on the upper half of the mounting block 13, and an RTK body 2 is threadedly installed on the top of the mounting block 13, and a calibration piece for horizontal calibration is provided on the surface of the rotating block 12. By designing the leveling bolts 10 and the leveling base 9 and combining the use of the calibration piece, the leveling bolts 10 at the corresponding position of the leveling base 9 are adjusted by observing the level of the calibration piece, and then the horizontal position of the RTK body 2 on the leveling base 9 is adjusted, and the RTK body 2 is calibrated at a point during the measurement process;

[0034] In addition, there is no restriction on the calibration method of the calibration part. It can be calibrated by emitting laser lines, calibrating by liquid bubble and ruler composition, calibrating by comparing the object with a reference object of known accuracy, etc. The method that can ensure the accuracy and reliability of the calibration process can be selected according to actual needs.

[0035] Furthermore, the calibration component includes a level 15 fixedly mounted on the surface of the rotating block 12 .

[0036] Furthermore, a mounting hole 16 is opened at the center of the mounting bracket 8, a fixing bolt 17 is threadedly installed between the bottom of the mounting plate 3 and the mounting hole 16, and a fixing bolt 2 18 is threadedly installed between the outer side of the top of the rotating block 12 and the clamping point of the mounting block 13.

[0037] Furthermore, the length of the measuring piece 14 is greater than the radius of the RTK body 2, which can facilitate manual rotation of the direction of the measuring piece 14 during the measurement process.

[0038] Furthermore, a horizontal calibration piece is fixedly installed on the lower surface of the measuring piece 14 away from the RTK body 2 at one end. The horizontal calibration piece is used to calibrate the horizontal direction of the measuring piece 14. The horizontal calibration method of the horizontal calibration piece here is not limited. It can be a laser line calibration, a liquid bubble and a ruler composition calibration, a calibration by comparing the object with a reference object of known accuracy, etc., which can ensure the accuracy and reliability of the calibration process. It can be selected according to actual needs to avoid loosening between the RTK body 2 and the mounting block 13 during the rotation of the measuring piece 14, resulting in the center of gravity of the measuring piece 14 shifting, affecting the height data between the measuring piece 14 and the ground, thereby affecting the overall measurement accuracy.

[0039] Furthermore, a distance sensor is fixedly installed on the lower surface of the measuring piece 14 away from the RTK body 2 . The distance sensor is located above the ground and is used to measure the height between the measuring piece 14 and the ground. The distance sensor is connected to the RTK body 2 by signal.

[0040] Working principle: When the detachable multifunctional RTK equipment fixing frame is used, the mounting bracket 8 is first placed on the top of the mounting plate 3, and the mounting plate 3 and the mounting bracket 8 are fixed together by fixing bolts 17, and the mounting block 13 is placed on the top of the rotating block 12 and fixed by fixing bolts 18. Then, the measuring piece 14 is sleeved on the mounting block 13, and the RTK body 2 is installed on the top of the mounting block 13. Then, the aluminum profile bracket 1 is erected on the top of the boundary monument, and then the support plate 4 is moved to the middle of the boundary monument. By rotating the flange 62, the clamping plate 63 on the rotating rod 61 can be driven to rotate until it contacts and locks with the surface of the boundary monument. The use of the rubber block 7 can make the aluminum profile bracket 1 more firmly fixed. This method can reduce the RTK body 2 on the top of the boundary monument. When encountering strong winds or other external forces, it will move or be disturbed by other interferences, causing the instrument to be unstable, thereby causing large errors in measurement accuracy.

[0041] In addition, considering that there are certain requirements for the conversion parameters obtained during the measurement of the RTK body 2, the accuracy of the calibration point itself is also particularly important, which is related to the reliability of the results, especially the impact on the elevation. Therefore, by designing the leveling bolts 10 and the leveling base 9 and combining the use of the level 15, the leveling bolts 10 corresponding to the leveling base 9 are adjusted by observing the level of the level 15, and then the horizontal position of the RTK body 2 on the leveling base 9 is adjusted, and the RTK body 2 is calibrated during the measurement process to improve the accuracy of the measurement. In addition, considering that the top of the boundary monument may not be It is not flat, so during calibration, the level 15 can be driven to rotate to the corresponding surface by rotating the rotating block 12. After the direction of rotating the measuring piece 14, the level of the level 15 and the horizontal calibration parts on the measuring piece 14 are observed. The horizontal position of the leveling base 9 is recalibrated by the leveling bolts 10, and the tightness between the RTK body 2 and the mounting block 13 is adjusted to correct the points of the RTK body 2. Combined with the use of the aluminum profile bracket 1, the main factors such as conversion parameters, human errors and instrument stability that affect the accuracy of the RTK body 2 during the measurement process can be reduced, thereby improving the measurement accuracy.

[0042] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
