Spacecraft assembly accuracy measurement data online acquisition system and method

Abstract

The invention discloses a spacecraft assembly accuracy measurement data online acquisition system and method. The spacecraft assembly accuracy measurement data online acquisition system comprises a lower computer control module, a communication module, an online module, a data acquisition module, a data processing module and a data management module. According to the invention, unified access andmeasurement data online acquisition of an electronic theodolite, a laser tracker and high-precision angle measuring equipment are realized, and automatic calculation of the measurement accuracy is realized through an algorithm library; automatic acquisition of a measurement preset value is realized through reading a three-dimension design model online, which supports rapid making of a measurementplan; the centralized storage of the measurement data can be realized, and the measurement data is associated with the model, the development stage and the process, so that online query and statistical analysis of the data is realized; and the spacecraft assembly accuracy measurement data online acquisition system is constructed by using a B / S architecture, which has the characteristics of convenient deployment and thin client; users can monitor the device through a browser according to permissions; and the measurement function which can only be achieved by the dedicated software deployed by asingle machine in the prior art can be realized, which is convenient for function expansion.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement, and in particular relates to an online acquisition system and method for spacecraft assembly accuracy measurement data. Background technique [0002] In order to ensure the accuracy and reliability of spacecraft assembly, it is necessary to measure, calculate and analyze precision data such as its structure, payload, installation position of instruments and equipment, and space angle during the product assembly process. At present, electronic theodolite, laser tracker and other equipment or self-developed high-precision angle measurement equipment are generally used for measurement in the field of spacecraft manufacturing at home and abroad. The measurement software of the stand-alone version is mainly deployed through industrial control computers or PCs to collect precision measurement data. Solve and store.

AI Technical Summary

Problems solved by technology

[0005] (1) Existing measurement software is generally custom-developed for a set or type of equipment, and the equipment connection, data acquisition and calculation functions are single and difficult to expand;

[0006] (2) With the method of single-machine deployment of measurement software, on the one hand, it is difficult to obtain design and process parameters online to support the rapid generation of measurement schemes; on the other hand, it is difficult to obtain real-time online measurement results, which need to be exported through storage media, which affects the efficiency of data use ;

[0007] (3) The accuracy measurement data has not been effectively organized and managed, and it is difficult to conduct historical data statistics and comparative analysis to support design and process improvement, and it is also difficult to query and trace data
