  • Detail

The major achievements of the "Eleventh Five Year Plan" highlight the "made in China"

the national major scientific and technological achievements exhibition of the eleventh five year plan has closed successfully recently. With the theme of innovation driven and leapfrog development, this exhibition has about 600 participating projects, which vividly shows the major scientific and technological achievements made by the country in the implementation of major scientific and technological projects, the cultivation and development of strategic emerging industries, the optimization and upgrading of industrial structure, and the development of agriculture and people's Livelihood Science and technology in the past five years. The Ministry of industry and information technology took the lead in organizing the research and development of four major projects: nuclear high-base, new generation broadband wireless mobile communication, high-end CNC machine tools and basic manufacturing equipment, and commercial large aircraft, which became the highlights of the exhibition. Since the implementation of these four programs, the current phased achievements have emerged, which can not only accelerate the cultivation of China's strategic emerging industries, but also drive the healthy development of related industries, providing scientific and technological support for comprehensively improving China's core competitiveness

wireless communication: three breakthroughs in standardization, industrialization and internationalization

as one of the 16 major national science and technology projects, the new generation of broadband wireless mobile communication is considered by the industry as a major strategic measure to occupy the commanding heights of the new generation of broadband wireless mobile communication technology and industry. Its exhibition area shows the application of urban and rural informatization based on TD-CDMA. In order to demonstrate the information-based urban management system, the urban management team members can upload the accident handling information to the central control system in real time through, and the headquarters can monitor the working status of each team member during the just concluded 10th processing and trade products exhibition (hereinafter referred to as the Gabor) and know the handling of each accident point at any time. The system was first tested in Dongcheng District in 2004

so far, the application of urban informatization based on TD-SCDMA has been piloted in more than 10 cities across the country, including Beijing, Hangzhou, Wenzhou, Kaifeng, and so on. A total of about 12000 TD industry terminals have been distributed, which has increased the urban problem discovery rate of these cities by more than 60%, reduced the problem settlement time from an average week to 12 hours, reduced the system construction cost by about 50%, greatly improved the efficiency of urban management, and significantly reduced the construction and operation costs

the TD-LTE quasi 4G scale demonstration, which was first presented at the WorldExpo, is also very eye-catching in this exhibition. After the development of the Eleventh Five Year Plan period, TD-SCDMA, TD-LTE and 4G (td-lte-ad-advanced) have achieved significant landmark results

td industrial alliance system is more stable, Secretary General Yang Hua told that in the era of 2G, foreign manufacturers once had a market share of 95% in China. With the special support and promotion, TD-SCDMA has formed a complete industrial chain with domestic enterprises as the core, including chips, terminals, systems, instruments and other links. The innovation ability and market competitiveness of domestic enterprises have been significantly improved, and the domestic market share can reach 85%. Chips were once the weakness of China's electronic manufacturing industry. A mature Chinese chip is the dream of countless equipment manufacturers. Now chip manufacturers such as Datang can become mainstream chip manufacturers in 3G TD-CDMA technology

Yang Hua said that in the future, TD-CDMA will further improve its market products and get greater support from the market. TD-LTE should accelerate its maturity, because China's 3G industry started late. When we mature, the opportunity has been missed, which makes it difficult to lead domestic manufacturers to intervene in the domestic market. To seize the opportunity in 4G, we should make the time point of maturity of the industry coincide with the time point of the rise of the overall international 4G market. In this way, domestic manufacturers can participate in the international 4G market in batches

Wang Xiaoyun, vice president of China Mobile Communications Research Institute, said: during the 12th Five Year Plan period, if TD-LTE is to be truly commercial, we must race against time, because the international market cannot wait. In June this year, China Mobile will conduct trials in six cities

Wang Xiaoyun said that during the Eleventh Five Year Plan period, TD-LTE made unprecedented breakthroughs in the three major fields of standardization, industrialization and internationalization, which is of cross era significance. In fact, since TD-LTE was approved by 3GPP in 2007, the TD-LTE industry has been formed in just two years. Such a speed of development has generally shocked foreign operators. In the field of TD-LTE, a trinity support system of government, industry and enterprises has been formed, which interacts and forms a joint force to promote the maturity of 4G, realizing great changes in the industrial development mode

it is understood that since 2010, TD-LTE experiments and pre commercial network construction are being carried out worldwide. More than 26 international operators around the world have started or are about to start the construction of TD-LTE pilot networks. It is expected that more than 10 countries and regions will start the commercial deployment of TD-LTE in 2011

nuclear high-level products: provide technical support for information and modern service industries

on the nuclear high-level booth, Tianhe-1 trillion times computer has a peak speed of 1206 trillion times per second, which makes this computer named Tianhe-1 rank first among the top 100 supercomputers in China announced on the same day, and also makes China the second country in the world after the United States that can develop billions of times of supercomputers

if Tianhe-1 is used to calculate a day, a current mainstream microcomputer will be 160 years. The storage capacity of Tianhe-1 is equivalent to the sum of the book collections of the four national libraries

Tianhe-1 is a product developed in the major science and technology projects of nuclear high-tech. Nuclear high base refers to core electronic devices, high-end general-purpose chips and basic software products. It is the core and soul of China's electronic equipment and national defense equipment, the basis for improving the core competitiveness of the information industry, and the technical guarantee for the sustainable and healthy development of the information industry and modern service industry

the central task of the major nuclear high-tech project is to overcome the key technologies of high-end general-purpose chips and basic software products represented by the central processing unit and operating system, realize industrialization, improve the independent innovation ability of enterprises, and support the leapfrog development of China's electronic information industry

during the Eleventh Five Year Plan period, nuclear high-tech major projects developed high-performance computers, intelligent embedded software platforms, high-performance digital signal processors, high-performance embedded CPUs, etc., with a total of 220 projects deployed, more than 300 enterprises, universities and scientific research institutes in 23 provinces, and more than 37000 scientific and technological personnel participating in the special implementation

during the 12th Five Year Plan period, major nuclear high-tech projects will further strengthen the combination of high-end general-purpose chips and basic software products, seize the opportunities brought by networking, take major applications as the breakthrough point, take breakthroughs in core key technologies and industrialization as the central task, and take improving market share as the goal to promote the improvement of the core competitiveness of the industry. By 2015, the proportion of China's integrated circuit design industry in the world has increased to 12% - 15%, the market share of basic software products has further expanded, and the profit margin of electronic information has significantly improved

high end CNC machine tools: from low-end wandering to high-end manufacturing

different from the new generation of broadband wireless communication and nuclear high base, high-end CNC machine tools and basic manufacturing equipment are the major scientific and technological projects that are most closely related to the manufacturing industry among the 16 projects, with basic, universal and strategic characteristics

in the exhibition area, the high-end CNC system and direct drive double swing milling head processing demonstration device independently developed by Dalian Guangyang Technology Engineering Co., Ltd. have become the only high-end CNC system and key executive components exhibits in this exhibition. The staff of Dalian Guangyang proudly introduced that the product covers the scientific research achievements of four topics, which fully reflects that the technical level of Dalian's high-end CNC industry is in the leading position in China

it is understood that during the Eleventh Five Year Plan period, the special project of high-end CNC machine tools and basic manufacturing equipment focused on the needs of key fields such as aerospace, ships, automobiles, power generation equipment and national key projects, the system deployed seven key tasks, including the development of mainframe, CNC system, functional components and key components, the development of common technologies, the construction of innovation platforms, user process tests and application demonstration projects

through the implementation of special projects, during the Eleventh Five Year Plan period, China's machine tool industry continued to develop steadily, its output value and output doubled, ranking first in the world, and the CNC rate and domestic market share of domestic machine tools increased significantly. Among them, the CNC rate of domestic machine tools increased from 26.4% at the end of the tenth five year plan to 56.7% at the end of the eleventh five year plan

at the same time, the special implementation has enhanced the innovation and competitiveness of key backbone enterprises, promoted the adjustment of industrial structure, and promoted the improvement of industrial concentration. At the end of the 11th five year plan, the total sales revenue of the top 10 machine tool enterprises in China accounted for about 25% of the sales revenue of the machine tool industry

during the implementation of the special project, focusing on the needs of key areas, we have overcome a number of key technologies, such as the design and manufacturing technology of large-span and ultra heavy machine tools, the design and manufacturing technology of ultra large vertical and horizontal rotary tables, and the processing technology of ultra wide and ultra long workpieces, and developed a number of CNC heavy bridge gantry five axis combined turning and milling machine tools, Jinan testing machine factory introduces manufacturing equipment with international advanced level, such as automatic stamping production line
