Xinhua News Agency, Hainan Wenchang, April 23 (Reporter Wang Nannan and Chen Xi) Have you ever thought that one day astronauts can access the Internet in the same way as we do in space and quickly browse information? This is no longer a dream as the spaceship on day one frees up.
"Compared with the previous spacecraft, the spacecraft No. 1 spacecraft for the first time the application of Ethernet technology for the future space station network communication technology to provide technical verification." China Aerospace Science and Technology Group VIII Zhouzhou day measurement and control communications subsystem technology leader Feng Shuyi In an interview with reporters, said Ethernet is the most common communication protocol standard used by existing LANs today, allowing for the exchange of information without space constraints. Valuable information in the Ethernet resource integration, with a large amount of information, efficient and fast transmission characteristics.
The existing spacecraft communication network system has been unable to meet the development needs in terms of transmission speed, service quality and scalability. With the development of aerospace technology, the business that needs to be transmitted and processed in the future space station will grow rapidly, and higher and higher requirements are placed on the internal bus communication system. Therefore, designing new network technologies suitable for the space station application environment has become one of the problems that must be solved.
"The first spacecraft day spacecraft application of Ethernet technology for the first time, the purpose is to provide technical verification for the future space station networking communications." Feng Shiyi said the day boat on the 1st equipped with a special "artifact" - high-speed communications processor . The processor, developed by China Aerospace Science and Technology Corporation's eight homes, is an important part of Ethernet communications for cargo spacecraft. It acts like a large airport that can direct a variety of small and large aircraft to take off and land, receive passengers from all over the world, Passengers sent around, is a "core transport hub."
"The high-speed communications processor not only plays a huge role in the world-wide monitoring and control communications of cargo spacecraft, but also lays a solid foundation for the establishment of the space station's gigabit communications network," said Feng Shiyi.
