A Design for Multi-parameters Real-Time Fusion Interpretation Method of Small Satellite Time-Varying Parameters

To realize rapid batch development target of small satellites industrialization, the first problem that to be solved is how to realize the automatic real-time monitoring interpretation of working states for small satellites. Traditional means of data automatic monitoring interpretation lack real-time monitoring ability for time-varying parameters, while artificial intelligence algorithm doesn’t support the practical engineering application for small satellites at present. Taking load current which is a classic time-varying parameter as an example for the problems above, this paper firstly carefully studies the influence factors and correlation interpretation demand of load current. Secondly, it analyzes the difficulties of automatic interpretation for load current. Finally, this paper based on the difficulties above expounds the overall design idea and the concrete realization methods of multi-parameters real-time fusion interpretation method, and the operation flow and interpretation logic of key links in this method are explained in detail. The method described in this paper has experienced engineering application verification of mass production of many small satellites, and can effectively realize the automatic monitoring target of load current.
