Automated control system for climatic and thermovacuum equipment parameters to test space industry products

Abstract

The work is caused by necessity to automate thermovacuum and climatic tests of space industry products at space branch enterprise. The aim of the work is the development of specialized system for monitoring modes and parameters of thermovacuum and climatic tests processes; substantiation of the chosen technologies of collecting, processing of primary data on pre-defined and current profile test as well as the data on technical condition of the applied test equipment and measuring instruments with various modifications. Methods and technologies: analysis of technological processes of product tests, design and layout of the automated control and monitoring systems, test running in a program mode, analysis of pre-defined test profile, parallel programming, object-oriented programming, object linking and embedding (OLE), storage and processing of XML-data, human-machine interaction, client-server interaction. Results: The authors have developed the automated control system for test parameters and its basic software and engineering solutions and components; have assessed the effectiveness of their application by the first results of operation. Conclusions: The use of the automated system consisting of up to several tens of test equipment units, networked and controlled by a single center by thermovacuum and climatic test processes, provides economic effectiveness, high technical-organizational and metrology level for on-ground test of space industry products.
