[0030] There are two low cylinders, including a first low cylinder 7 and a second low cylinder 9, and there are two high cylinders, including a first high cylinder 6 and a second high cylinder 8. The first low cylinder 7, the second low cylinder 9, the first high cylinder 6 and the second high cylinder 8 are respectively arranged at four non-adjacent positions of the base 1, and the quadrilateral formed by the connecting lines of the four cylinders is an irregular trapezoid.

[0031] A method for verifying the receiving software of a laser measuring equipment product uses the aforementioned laser measuring equipment product receiving software verification standard, measures the verification standard through the laser measuring equipment product, compares the measured data with the benchmark data of the verification standard, and provides the functional correctness of the laser measuring equipment product receiving software.

[0032] Before using the verification standard, its dimensions and form and position tolerances are tested with a coordinate measuring machine, and the data obtained are used as standard values ​​for comparison.

[0033] When the verification standard is measured by laser measuring equipment, the height difference between the high cylinder and the low cylinder is measured and evaluated, and the position between the high cylinder and the low cylinder is measured and evaluated.

[0035] Embodiment 2:

[0036] The technology of the present invention can quickly verify the receiving software of laser measuring equipment products in a simple and intuitive way. At present, there is a gap in the industry in the use reliability verification technology for similar laser measuring equipment measurement software, and there is no technology that can determine whether the receiving software of laser measuring equipment products meets the use requirements. Whether the receiving software of laser measuring equipment products covers the requirements of various functions to be used needs to be verified using certain standard digital models and physical standards. This patent is designed to verify whether the receiving software of laser measuring equipment products can be used normally and whether various functions meet the use requirements before it is put into use. The design of the present invention is simple to operate, has strong applicability, and has low design cost, and can meet various certification and audit requirements.

[0037] By using a dedicated standard to test the correctness of the function, the implementation of the function and accuracy of the laser measurement equipment product receiving software is verified; by using a dedicated standard digital model, the ability of the product receiving software to read data is verified to determine whether the product receiving software has lost or misread the digital model.

[0038] The base plate 1 is the zero point of the Z axis of the coordinate system, and requirements are put forward for its flatness and roughness as a physical feature for evaluating flatness. The positioning reference holes 2, 3, 4, and 5 are used as characteristic reference points for establishing the coordinate system, and also as characteristic elements of digital simulation. The height difference between the high cylinders 6, 8 and the low cylinders 7, 9 can be used as a physical feature for the vertical distance evaluation of the software, and also as a physical feature for position. The cone 10 is a physical feature for evaluating taper, the sphere 11 is a physical feature for evaluating roundness / sphericity, the inclined surface 12 is a physical feature for evaluating inclination / angle, the annular body 13 is a physical feature for coaxiality / axis-to-plane perpendicularity / single runout / total runout, the slotted hole 14 is a physical feature for symmetry / face-to-face parallelism / line-to-face parallelism / face-to-face perpendicularity, and the arc groove 15 is a physical feature for radius / line profile / face profile.

[0039] By using laser measuring equipment software to perform contact detection on the laser measuring equipment product acceptance software verification special standard, detect each element in the special standard, evaluate one by one, and compare the test results with the results detected by the coordinate measuring machine to verify the correctness of its function and evaluation. Some laser measuring equipment software may not be able to analyze and evaluate the position tolerance, verticality tolerance, etc., which can determine that the laser measuring equipment software cannot meet the use requirements, or the comparison results are very different. Under the premise that the laser measuring equipment itself is qualified, it can be determined that the analysis and evaluation ability of this geometric tolerance is defective. This intuitive test can be operated by non-software professional metrology and calibration personnel. It is intuitive and convenient, and does not require high professional skills.

[0040] like Figure 1 , Figure 3 , Figure 4 As shown, the base plate 1 of the special standard device for receiving software verification of laser measuring equipment products is respectively manufactured with positioning reference holes 2, 3, 4, 5, high cylinders 6, 8, low cylinders 7, 9, cones 10, spheres 11, inclined surfaces 12, annular cylinders 13, slotted holes 14, and arc grooves 15. Before use, the coordinate measuring machine is used to detect the dimensions and geometric tolerances of the special standard device, and the data obtained are used as the standard value for later judgment.

[0041] When using laser measuring equipment to measure special standards, the coordinate system establishment method and reference selection should be consistent with those when measuring with a coordinate measuring machine to ensure the rationality of the comparative evaluation.

[0042] The base plate 1 is the zero point of the Z axis of the coordinate system. The flatness of the base plate 1 is measured and evaluated by means of point sampling construction, the height difference between the high cylinders 6, 8 and the low cylinders 7, 9 is measured and evaluated, the positionality between the high cylinder and the low cylinder is measured and evaluated, the taper and angle of the cone 10 are measured and evaluated, the roundness / sphericity of the sphere 11 is measured and evaluated, the inclination / angle of the inclined surface 12 is measured and evaluated, the coaxiality / axis line to plane perpendicularity / single run-out / total run-out of the annular body 13 are measured and evaluated respectively, the symmetry / face-to-face parallelism / line-to-face parallelism / face-to-face perpendicularity of the slotted hole 14 are measured and evaluated respectively, and the radius / line profile / surface profile of the arc groove 15 are measured and evaluated respectively. By comparing the test results with those detected by the coordinate measuring machine to verify the correctness of its functions and evaluations, it can be determined that the software of the laser measurement equipment cannot meet the use requirements, or the comparison results are quite different. Under the premise that the accuracy of the laser measurement equipment itself is not qualified, it can be determined that the analysis and evaluation capabilities of the geometric tolerance are defective.
