Embodiment Construction

[0210] The invention mainly provides the basic principle and implementation method of the optical self-collimation dynamic precision level measurement method, and carries out the overall design of engineering technology for the key modules such as the inertial synchronous repeating platform and the level error detection tool. The invention also deduces the Measurement model and error model of optical self-collimation dynamic precision level measurement method.

[0211] The invention can adopt different technical solutions for moving objects with different dynamic ranges. When the change range of the horizontal information of the inspected object is smaller than the measuring range of the autocollimated collimator (≈12.5′), the inertial synchronous repeating platform can be omitted, and the horizontal error detection tool is only required to be directly fixedly connected to the inspected object. When the change range of the horizontal information of the object to be inspected i...

Abstract

The invention relates to an optical autocollimation-type dynamic precise horizontal measuring method, which is used for solving the problem of the horizontal information precise measurement under the situations of complete static status, quasi-static status-quasi-dynamic status and complete dynamic status. Automatic-leveling principle of liquid is used as a reference beachmark of the ground level, an autocollimation-type parallel optical tube is used as a horizontal error detection tool, an inertia synchronous repeating platform is used as a dynamic measurement transitional beachmark, an optical coding angle measuring element is used for realizing the measurement of the position of the repeating platform, and a measuring system generally consists of a detection device, an information processing and control circuit and a main monitoring platform which are connected with one another through wires and cables. Due to the adoption of the method, high-precision horizontal posture information can be provided for a movable carrier (such as a vehicle, a ship, an airplane and the like) in real time. The method can also be used for measuring horizontal structural deformation of the carriers, for identifying the inertial guidance horizontal precision, and the like.

Description

Technical field [0001] The invention relates to an optical self-collimation dynamic precision level measurement method, which belongs to the technical field including optical self-collimation measurement, inertial navigation technology, motion carrier attitude measurement, level detection technology, object structure deformation measurement, etc., especially applicable to Real-time measurement in full-static, quasi-static-quasi-dynamic, and full-dynamic situations. Background technique [0002] As a general-purpose detection and measurement tool, the horizontal error detection tool has a wide range of applications in many fields. Because of its specific use requirements and different use environments, its performance indicators and design principles vary widely. Combining image levels, electronic levels, etc. have high measurement accuracy (measurement error: ≤1″), but they are mainly used for precise level measurement in static environments. Navigation equipment based on in...
