Abstract: | In order to solve the shortcomings of the existing flight test monitoring mode, such as single data source, insufficient expansibility and poor system robustness, this paper studies the multi-source data real-time monitoring technology based on DDS (data distribution service). Without changing the hardware architecture of the real-time monitoring system, according to the data characteristics and task requirements of the existing real-time monitoring system, Using task container technology to distribute and execute flight test data processing tasks, realizing distributed real-time receiving and analysis of flight test data and centralized control of flight tasks; using analytic algorithm based on template method to realize data access ability of multi-source signal sources of the system, improving the scalability of the system; using task distribution mechanism based on serialization and activity check to realize At the same time, the use of DDS communication protocol improves the communication ability of the real-time monitoring system in the bandwidth limited state. The practical application shows that the real-time monitoring system with this technology has the advantages of high reliability, high stability and dynamic scalability. |
