【Abstract】 The diversity and complexity of space tracking and control tasks continue to increase. With the change and adjustment of data sampling frequency, the original time-driven processing mode has gradually been unable to meet the demand. The data measurement software developed based on the time-driven software architecture is becoming more and more complex, and the difficulty of maintenance is increasing. In response to the above problems, this paper proposes a data-driven software architecture of the measured data’s real-time processing on tracking ships. Under the Kylin operating system, the real-time processing software for external test data is realized based on this architecture. The software is composed of multiple data-driven functional components, and each component uses a service bus to achieve data interaction and integration. Experiments show that the data-driven software of the measured data’s real-time process based on this architecture solves the problems of excessive delay and sequence alternations and can meet the requirements of current space tasks.更多还原
