[Reporter Wu Mengqi] On the afternoon of March 6, the opening day of the Guizhou Delegation Delegation Open Day at the 5th Session of the 12th National People's Congress was held at Beijing Guoyi Hotel. Since the world's largest single-aperture spherical radio telescope (FAST) project is located in Guizhou Province, the FAST project has become a major concern. Liao Fei, deputy to the National People's Congress and director of the Guizhou Provincial Department of Science and Technology, told the Global Times reporter that "China Skyeye" is expected to complete acceptance within two years.
Liao Fei responded to a question from the Global Times reporter about the status quo of “China’s Eye of Heaven†and stated that the general debugging period for similar devices in the world is 2-5 years. This project is more complicated. We understand that it takes two years to complete the commissioning. At present, our scientific team is still working day and night. The second half of the year may enter the commissioning stage and it is expected to be completed within two years.
Liao Fei said that "Heavenly Eye" is a major scientific and technological project and a world-class science and technology project. According to the actual situation, Guizhou is to "build up the antenna and connect well with the gas." The so-called "laying up an antenna" must be on the one hand consistent with the country's major strategic plan for building a world-leading science and technology country, and must be carried out. At the same time, it must closely track the science and technology of exploring the mysteries of the space. “Getting good gas†refers to the implementation of regional science and technology innovation strategy guided by big data.
According to Liao Fei’s introduction, Guizhou has recently had a preliminary goal of “three stepsâ€: One is to build the Guizhou Radio Astronomy Observatory with the National Astronomical Observatory. This work has not been pushed forward since it was under construction. Now we are actually Promote this work. The second is that we have a specific measure to promote the development of big data and large radios. Regardless of whether to do semantic analysis or astronomical big data processing, the needs of all parties need to be aggregated to require a relatively powerful computing device. This device should not only meet the requirements of fast numerical calculations, that is, be fast, but also have the functions of semantic analysis, visual recognition, and image recognition. In terms of image, it is the human brain, and it must be calculated quickly and logically. , There must be visual and other processing functions. These needs are put together. Our preliminary idea is called "Science Science Computing Device." It is also a brain in Guizhou that promotes science with supercomputing power. Third, on these two foundations, we must work with the National Astronomical Observatory Guizhou Radio Astronomy Observatory to promote the construction of big data astronomical data research centers and even the construction of national laboratories.
