Abstract

The invention relates to a method for resisting a single event effect of a high-speed optical interface module in a space environment. The method comprises the following steps: a, classifying influences generated by the single event effect; and b, respectively performing corresponding processing according to classification results. The method has the advantages of being efficient, complete in function and rapid in recovery.

Description

technical field [0001] The invention relates to an anti-single event effect method for a high-speed optical interface module in a space environment. Background technique [0002] The information system is the core system of the space station, and the space networking communication network is the backbone of the information system, which connects the load electronic equipment of each sub-system of the space station. With the development of aerospace technology, the business that needs to be transmitted and processed in the space station has grown rapidly, and higher and higher requirements have also been placed on the internal communication system. The 1553B bus commonly used in the prior art can no longer meet this demand, so it is urgent to design a new network technology suitable for the application environment of the space station. Ethernet is the mainstream technology for terrestrial LAN networking, and Ethernet switches have been used in space cabins of space stations....
