Problems solved by technology

Applying this method, in order to ensure that the product is within the measurement range of the spatial measurement network, it is necessary to continuously move the instrument, repeatedly build the station, and once adjusted during the measurement, it needs to be recalculated. It is impossible to intervene in the adjustment operation, and the measurement process is time-consuming exhaustion, inefficiency

Abstract

The invention relates to an antenna assembly detection method. An antenna tower is a basic structure of the antenna. A set of sub-reflector assembly is respectively arranged on each side of the antenna tower. A feed assembly is respectively arranged below each sub-reflector assembly. The above-mentioned parts are assembled on an assembling platform. Detection systems employed by the detection method are a laser tracker system, a theodolite system and a laser radar system. A space calibration point is arranged, and a spatial calibration process is implemented, such that a coordinate transformation relationship among the three detection systems is determined. One detection system is used for measuring the assembling platform, and for determining the transformation relationship between the assembling platform and an assembling reference coordinate system. When the parts are installed, the parts are installed according to the installation requirements and measuring characteristics. Detection means with lower implementation intensity and higher sampling efficiency is adopted.

Description

technical field [0001] The invention relates to a posture detection technology for antenna assembly, which applies multi-measurement equipment integration technology and proposes real-time monitoring and measurement for the posture measurement of reflector components. Background technique [0002] For antenna products with curved surface parts, the traditional detection method in the assembly stage is generally theodolite detection method. Use multiple theodolites to build a space measurement network to complete the inspection of the whole process of the assembly stage. [0003] The antenna system is generally composed of reflection components (main and sub-reflectors), source support components, support components and other parts. When the antenna system has many components ( figure 1 As shown, the antenna tower body and the antenna tower top plate are used as the basic structure, and 5 sets of sub-reflector assemblies and 5 sets of feed source support assemblies are inst...
