The Thermal Simulation and Control Technology in Spacecraft Vacuum Thermal Test
The thermal simulation and control system is the core of vacuum thermal test of the spacecraft, which is used for tests design, data acquisition, thermal simulation and control, data management. In order to meet these application requirements, research contents and methods of keys techniques were expounded, which mainly includes three aspects: modeling analysis of test design workflow based on UML, architecture design and function design of test design software based on database and ASP; establishing universal driver function library based on VISA and SCPI, parallel driver design based on multithread technology; control mode and control algorithm design based on control objects requirements of the thermal simulation. Then the paper introduces the application of the research achievements, including test design software, data acquisition software, thermal simulation and control software. Finally, the paper prospects the main development direction of the thermal simulation and control technology along with the booming development of the China`s space industry.
