Abstract:

Due to the current demand for space environment test of the spacecraft components products is increasing, the degree of automation of the test process control system requirements and its adaptability to different test requirements are more stringent. In order to improve its level of automation and flexible and adaptable, with small thermal vacuum test system demand background, the test process automation needs and suitability conditions were analyzed, an automatic control method can be adapted to different needs and conditions is proposed and designed. This method is easy to be implemented, process control and reliability protection for equipments and instruments of the system are through various sensor parameters of the test system as a reference criterion, and with a relatively intelligent control strategy to adapt to different experiment requirements of the test system flexibly. After testing to verify that the control method is suitable for small thermal vacuum testing procedures, with strong adaptability, high degree of automation, can significantly improve the small thermal vacuum test process automation level to meet demands of space environment tests for the intensive spacecraft components products.
