"Hefei Technology" sets up the "Information Highway" of the Cabin Card

How does the space station of "in" "communicate" with the ground? On July 24th, the first scientific experimental cabin of China Space Station -asked the Tian Tian experimental cabin successfully launched. The reporter was informed that many important supporting products such as optical modules, optical cables, optical cable components, and cockpit optical fiber connectors in the Tiangtian Experimental Cel were asked by the Eighth Research Institute of China Electronic Technology Group Corporation in Hefei (hereinafter referred to as "China Electric Science and Technology Section Department 8)) independently developed, and these equipment jointly "constructed" the "information highway" of the test compartment.

Gao Zeren is developing related products research and development

8 scientific researchers in China Electric Science and Technology are developing related products research and development

Recently, science+studio came to 8 China Electric Sciences to see how the researchers here "moved" the information on the ground high -speed network.

"Hefei Technology" allows the world between heaven and earth

Realize information two -way transmission

On July 25, the Shenzhou 14th astronauts have successfully entered the questioning compartment of the Qi Tian. This is the first time that Chinese astronauts have entered the scientific experimental cabin on the orbit. They will follow the plan to carry out a series of scientific experiments as planned. In the past few days, everyone has also witnessed the figures of astronauts working in the cabin on many media platforms.

The images and videos from outer space are mainly transmitted to the earth through the space station information high -speed channel built by the China Electric Science and Technology 8 developed equipment.

The reporter was informed that on the Cabin Card, many important supporting products such as optical modules, optical cables, optical cable components, and cockpit optical fiber connectors developed by China Electricity Department 8. Relying on these products, various images, voice, instructions, data and other information can be transmitted high -quality two -way high -speed transmission between the cabins and heaven and earth between the space stations.

"We have 3 series 9 products for the Sky Cabling Fangs this time, with a total of hundreds of devices. It can be said that the main information transmission on the sky cabin is performed through our device." China Electric Science and Technology 8 Gao Zeren, the person in charge of the Aerospace Component Engineering Center, introduced that the entire set of information transmission equipment has high stability and high transmission rate, which greatly improves the quality and speed of information transmission. "For example, we can clearly see the action details of the astronauts in the videos of returning, and the call between ground staff and astronauts is more stable and clear."

Break through many key technologies

Successfully developed "Curbine Fiber"

Building equipment on the earth to achieve high -speed communication is now easy, but the same scene "put in" space is not easy.

In 2014, China Electric Science and Technology 8 received the task of providing information transmission products to the space station. It took many years to study and conduct a series of key technologies such as equipment space adaptability and large -scale optical fiber interconnection connection. In 2021, some of the information transmission products developed in 8 have been configured to successfully lift off in the sky and core compartment. Among them, this time the core component of the space station on the cabin -the cabin fiber connector, which uses a number of advanced technologies.

"In order to realize the interoperability of data from inside and outside the cabin, you need to wear the cabin optical fiber. It can be understood as a fiber that extends from 'outside' to‘ inside the house ’.” Gao Zeren introduced.

But the space environment is not a simple "out -of -house". Outreach fibers must be able to resist high and low temperature and radiation resistance, and have multiple environmental adaptability. "We have re -designed, transformed and optimized through a large number of experiments for the structure of fiber material structures to solve a series of problems such as external anti -radiation large -scale light interconnection of space station compartment." Gao Zeren said that because China Space Station plans to run for more than 10 years, it is planned to run for more than 10 years. Fiber also needs to have the "long life" attribute in this environment.

Another key problem is the problem of gas sealing brought by the cabin fiber. "Outside the cabin belongs to vacuum, the cabin is normal and normal pressure. Although the fiber is put on the cabin, the cabin still needs to be seal. This is related to the safety of the space station platform." Gao Zeren introduced that after years of research and development, the team successfully solved the space environment in the space environment. The problem of air -sealing, while opening a direct channel for transmission of data inside and outside the space station, ensures a complete sealing state of the cabin.

Continuous improvement of equipment performance

The product will also be on the "Mengtian Cabin"

Starting in May last year, Gao Zeren and his team went to the location of the Cabin Cabin for many times to debug and maintain the equipment. In May this year, he and the team went to Wenchang to carry out important guarantee before launch.

"There are 6 people in the team, and they will be tested every day, and the work plan is full." Gao Zeren said that in Wenchang, the guarantee of the guarantee for the service of the skycase service from all over the country. Excited, I feel that I can contribute to the space station of the motherland. When I saw that the sky cabin was successfully lift off and the successful connection with the sky and the core cabin, Gao Zeren's heart was also very emotional.

"China Electric Science and Technology 8 has always been on the road of unremitting pursuit of aerospace dreams. Our products have been widely used in spacecraft such as China Space Station, Tiangong No. 2, Tianzhou No. 1, etc., showing 'Anhui Creation' '' Hefei Creation '' Hard power. "Gao Zeren said that at present, the eight devices in the space station are running well. On the "ground", the eight teams are still constantly engaging in technical research, hoping to further improve a series of performances such as radiation resistance of the product. "In the subsequent dream of the Dream Cabin, the information transmission equipment of 8 will also be used."
