The Study On Key Plug And Play Technologies Of Integrated Bus System In New Generation Of Satellite

Satellite-borne integrated bus system is used for the electrical connection and data alternation between satellite platform and payload aimed at the supervision of the payload status and control of the operational management. Along with the continuous development of aerospace cause, satellite system are widely used more and more because of its specialties of wide area coverage, short revisiting time and no national boundary limit, therefore it drives the development of payload technology. Through the programming and evolution for many years, satellite-borne payloads tend to the direction of complete function, great varieties and widely distributed manufacturers, resulting in the requirements of adaptability design of multi-payload to satellite common platform. So it is very important to realize wide adaptability of satellite common platform to study plug and play technology for satellite-borne integrated bus system by use for reference of plug and play technology and concept of domestic electronic products.This paper investigates the new generation plug and play satellite-borne integrated bus system and considers the characteristics and requirements of on–orbit operation spacecraft application. Furthermore, we analyze the plug and play objects from data interface, interactive content and constraint conditions. Based on the mature industrial bus and current bus technology used in the space application, we propose the combining scheme between the high speed and low speed bus for satellite, and implement a plug and play system integrated bus scheme by software for new generation satellites, design the relevant bus protocol and software architecture to guide the engineering application.In the research work, by building the experimental system consisting of the payload simulation equipment, routing unit, the central computing system, we verify our proposed software architecture and information processing flow, which can be able to meet the plug and play requirement of the payload.
