[0057] It is found through research that the prior art has the following disadvantages: when working, the platform is leveled by the angle screw, so that the circle on the platform is horizontally centered, but at this time, the platform still has a small inclination in two orthogonal directions, which affects the measurement accuracy of the platform.

[0058] Therefore, how to improve the azimuth angle of the platform rotation more accurately is a technical problem that needs to be solved in the art.

[0059] The deficiencies of the above solutions are the results of the inventors after practice and careful research, therefore, the discovery process of the above problems and the solutions proposed by the present disclosure to solve the above problems should be the contributions of the inventors to the present disclosure in the process of the present disclosure.

[0060] It should be noted that like reference numerals and characters refer to like elements throughout the following detailed description with equal dignity, and once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0061] Some embodiments of the utility model will be described in detail below with reference to the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0062] As Figures 1 to 4 Some embodiments provide a high-precision two-dimensional level, comprising: a body 1; in order to improve the stability of the body 1, the bottom of the body 1 is provided with a base, the base is suitable for adjusting the horizontal angle of the body 1, and the body 1 is convenient to fix. Platform 2, which is arranged on the upper end of the body 1, and the upper end is provided with a circular water bubble; a measuring device is arranged on the platform 2, the measuring device is electrically connected with the control module, and the measurement data measured by the measuring device is transmitted to the control module. Horizontal assembly 3, which is arranged inside the body 1, and is provided with a double-axis tilt compensator 4 inside; when the inclination range of the platform 2 is in the range of 4', the double-axis tilt compensator 4 can accurately compensate the azimuth angle of the platform 2. The control module is electrically connected with the horizontal assembly 3, the platform 2 and the double-axis tilt compensator 4 respectively, and is configured to control the double-axis tilt compensator 4 to measure the levelness of the platform 2 relative to the horizontal plane after the circular water bubble is centered, so as to obtain a compensation coefficient. The double-axis tilt compensator 4 can output the levelness of the current instrument relative to the horizontal plane, and the measurement accuracy is ±3', so that the azimuth angle of the platform 2 rotating is more accurate. After the body 1 is placed horizontally, the measuring device is fixed on the platform 2, the levelness of the platform 2 is adjusted, so that the measuring device remains in a near-horizontal state. However, since the platform 2 cannot guarantee absolute level, after adjusting the levelness of the platform 2 relative to the horizontal plane, there is still a large error in the detection of the measuring device. Through the setting of the double-axis tilt compensator, after the water bubble is centered, the double-axis tilt compensator compensates the small inclination angle in two directions.

[0063] Reference is made to the drawings Figure 3The biaxial tilt compensator 4 comprises a compensator seat 41 arranged in the horizontal assembly 3, an accommodation groove 42 is arranged at the upper end of the compensator seat 41, and a liquid 45 is arranged in the accommodation groove 42; a liquid supplementing port 50 is arranged on the bottom wall of the compensator seat 41, and the liquid supplementing port 50 is suitable for conveying the liquid 45 into the accommodation groove 42, and the liquid 45 comprises dimethyl silicone oil. The dimethyl silicone oil has the characteristics of high transparency and suitable refractive index, good heat resistance, strong chemical stability and low volatility. A lens 43 is arranged at the upper end of the compensator seat 41 and below the liquid 45; the lens 43 comprises a converging cemented lens, and the converging cemented lens has the characteristics of good photochemical performance and strong mechanical stability. A water bubble cover 44 is arranged on the upper end of the accommodation groove 42; a gap is arranged between the liquid surface in the accommodation groove 42 and the top wall in the water bubble cover 44; a biaxial unit board 47 is arranged on the side wall of the compensator seat 41 and electrically connected with a control module; wherein the biaxial unit board 47 emits light to the lens 43, and the light is reflected by the liquid 45 and returned to the biaxial unit board 47. The light emitted by a point light source 48 is imaged on the opposite side of the lens 43 through the lens 43, and a light source image is formed at the place with equal focal length, and the image is received by the liquid 45, and the distance between the liquid 45 and the lens 43 is less than the distance between the point light source 48 and the lens 43, and a magnified image is formed.

[0064] With reference to the accompanying drawings Figure 3 A through hole 46 is arranged in the compensator seat 41, and the through hole 46 is communicated with the accommodation groove 42; the lens 43 is arranged at the upper end of the through hole 46 and abuts against the inner wall of the through hole 46.

The parallel light after passing through the lens 43 is incident into the liquid 45, reflected at the interface between the upper part of the liquid 45 and the air, and imaged on the plane array image sensor 49 (CCD or CMOS) through the lens 43; when the platform 2 is tilted forward and backward, the image of the point light source 48 moves along the X direction; and when the platform 2 is tilted left and right, the image of the point light source 48 moves along the Y direction. The distance of the movement of the image of the point light source 48 in the X (or Y) direction is measured, and the tilt angles of the X and Y axes are calculated, so that a compensation coefficient is obtained. The control module calculates the final measurement result according to the compensation coefficient and the measurement data, and the measurement accuracy is improved.

[0066] Reference is made to the accompanying drawings Figure 3 The distance from the point light source 48 to the lens 43 is greater than the distance from the lens 43 to the liquid 45, so that the light reflected to the area array image sensor 49 is projected as an enlarged image.
