For the security risk caused by foreign products in aerospace ground test system, an aerospace ground test system was designed based on Kylin operating systems. Based on the analysis of the work principle of the system, a relevant application testing software by using QT on Kylin operating systems was designed. Methods of “database + binary file” database storage and driver design for the key technologies of fast data storage and data acquisition card driver design were put forward. Results of the test show that the localized test system is excellent in reliability and real - time performance to meet the requirement of aerospace ground tests.
