Space intelligent bus interface system and space intelligent network system using same

Abstract

The invention discloses a space intelligent bus interface system and a space intelligent network system using the same, and relates to an interface system and a network system. The problems that a traditional Space Wire bus interface does not provide a space equipment standard power supply, is low in synchronization precision, cannot synchronously work when a network or communication is interrupted, and does not have self-description, self-organization, dynamic adaptive reconfiguration, self-cognition and self-diagnosis functions are solved. The interface system comprises a Space Wire bus interface, a power supply interface, a synchronous pulse interface and a bus interface controller; the network system comprises n space intelligent interface systems; the Space Wire bus interfaces of all the space intelligent interface systems are connected in parallel; and another network system comprises a main space intelligent interface system, n slave space intelligent interface systems, a power supply distribution module, a Space Wire bus router and a synchronous distribution module. The disadvantages of the prior art are overcome by the space intelligent bus interface system and the space intelligent network system; and the space intelligent bus interface system and the space intelligent network system are suitable for being used in the fields of various space vehicle integrated electronic interface systems and network systems.

Description

technical field [0001] The present invention relates to an interface system and a network system. Background technique [0002] The Space Wire bus was jointly developed by the European Space Agency, European Space Corporation and academia. It was proposed in 2003, namely ECSS-E-50-12A[1], and a revised version ECSS-E-ST-50-12C was proposed in 2008 [2]. It can form a high-speed, point-to-point, full-duplex serial bus network, based on two commercial standards IEEE-1355-1995 and LVDS, absorbing the advantages of 1394 bus, ATM and Ethernet technology, while taking into account aerospace The characteristics of the application. This bus standard is dedicated to the processing of spacecraft payload system data and control information to meet the goal of high-performance and high-speed data transmission in the future, and provides a unified infrastructure for connecting sensors, data processing units, and large-capacity storage. In addition to having good electromagnetic compati...
