Abstract
With the development of aero-engine,the measured parameters needed to be acquired in the aero-engine test become more and more,and the correlative performance calculation becomes more and more complex,the amount of the data stored increases gradually,which brings higher demands for data acquisition system.The data acquisition system is introduced,which is designed based on multi-threading technique,and the development environment is MFC(Microsoft foundation classes).The different functions,such as data acquisition,realtime display and data calculation,are assigned to the different threads of concurrent execution,in the meantime,a reasonable method of thread scheduling is adopted,which can improve the overall performance of data acquisition system,thereby the system can satisfy the need of aero-engine test.关键词
