Abstract:In view of the difficulties of data fusion, single transmission protocol, and poor flexibility of extension in the service-oriented client-server (C/S) architecture monitoring mode, the data distribution service (DDS) technology is introduced into the flight test real-time monitoring system, and a complete set of solutions is formed by combining the WPF graphics engine technology. On the premise of fully compatible with the current architecture specifications, DDS technology is used as the data transmission middleware, which effectively improves the real-time performance of the flight test monitoring system, strengthens the granularity of multi-source data fusion, and reduces the integration difficulty of the test resources; WPF graphics engine technology is used to build the real-time monitoring visual editing platform, and finally realizes the multi-source data reception in the air space integrated monitoring environment , processing, distribution, visual display and other key technologies. This scheme has been successfully applied in the ground real-time monitoring of flight test.
