Abstract

The system and method for online acquisition of spacecraft assembly accuracy measurement data of the present invention include a lower computer control module, a communication module, an online module, a data acquisition module, a data processing module and a data management module. The invention realizes the unified access of electronic theodolites, laser trackers, and high-precision angle measuring equipment and online collection of measurement data, and realizes automatic calculation of measurement accuracy through an algorithm library; and realizes measurement preset values ​​by reading a three-dimensional design model online The automatic acquisition supports the rapid formulation of the measurement plan; it can realize the centralized storage of the measurement data, and associate the measurement data with the model, development stage, and process for management, and realize the online query and statistical analysis of the data; the system adopts B / S architecture construction , has the characteristics of easy deployment and thin client. Users can monitor the device through the browser according to the authority, and can realize the measurement function that can only be realized by the special software deployed in the original single machine, 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
