Facing the future far sea, high speed and wide range of far sea operations, based on the analysis and research of reliable distribution and timeliness requirements of data chain messages, combined with the high dynamics of satellite communication ground combat platforms causing dynamic changes in satellite network star-ground node topology, this paper proposes a multi-star multi-link channel access technology for data chain applications, which is based on real-time access to channel connectivity and routing information. This technique selects the optimal access platform based on the real-time acquisition of channel connectivity and routing information, taking into account the channel quality and time delay. The results show that this technique is suitable for efficient addressing of data link messages, improving the message delivery rate and reducing the network load.
Aiming at the requirements of data query, monitoring, analysis and display during system operation, a real-time distributed data collection and analysis system is designed. This paper first analyzes the processing process of data acquisition and analysis, on this basis, combined with the actual application requirements, minimizes the changes to the existing equipment environment, adds intelligent acquisition cards at the device interface for signal-level or business-level data collection, and adopts cloud/server technology and MQTT lightweight communication technology to visualize the system operation process, and supports on-demand subscription to ensure that problems in the process of system operation can be found in a timely and effective manner.
