Analysis of the development of domestic electronic measuring instrument industry
The electronic measuring instrument industry was highly valued by the state at the beginning of the founding of New China. During the “First Five-Year Plan” and the “Twenty-Five” Plan, there were 12 electronic measuring instruments in the 156 major projects built by the state at that time, accounting for 7.7% of the national major projects. By the end of the second five-year plan, 11 factories and 1 research institute with international advanced level at that time were basically built, which laid a preliminary foundation for the development of China's electronic measuring instrument industry.
The historical mission of the industry
Electronic measuring instruments are responsible for the important mission of national security, economic development and scientific and technological progress. Whether from an economic point of view, an industry perspective, a national security perspective, or a technological advancement perspective, it is possible to see the inextricable relationship between electronic measuring instruments and the electronic measuring instrument industry.
The electronic measuring instrument is based on circuit technology and integrates electronic test and measurement technology, computer technology, communication technology, digital technology, software technology, bus technology, etc. to form a single machine or automatic test system. In the form of electricity, non-electricity, and light quantity, measure various parameters of the measured object or control the operation of the system under test. The application of electronic measuring instruments in all fields of the national economy is an indispensable condition for realizing national scientific and technological progress and original core technologies.
Electronic measuring instruments should be synchronized or advanced ahead of other high-tech developments. It is a fusion of various high technologies and supports the development of various high technologies. Upgrade the product structure to effectively increase the domestic market share. Electronic measuring instruments are related to economic and strategic industries. Internationally, electronic measuring instruments in developed countries generally account for 4% of the gross national product, but its driving force on gross national product is 66%, and its correlation with the national economy. More than 90%. The electronic measuring instrument industry is a manifestation of a country's comprehensive technical level, an important symbol of national defense strength, and an important guarantee for the sustained and stable development of the national economy.
Diversified development model
At the beginning of the reform and opening up in 1978, the self-designed electronic measuring instruments were basically medium and low-end products, and the high-end products were in imitation. The research and development work takes the backbone enterprises as the leader to develop new products according to the division of products, and the products of the backbone enterprises represent the level of the industry products. In 1978 and before, China was strengthening the period of national defense construction. Therefore, the technological development of electronic measuring instruments is closely related to the needs of national defense. From technical indicators, measurement functions to working environments, it is necessary to adapt to the requirements of war. Development direction of integration, reliability and reliability.
The reform and opening up has made China's electronic measuring instrument industry face the new situation of challenge and development. The "challenge" mainly comes from two aspects: the first one is the serious challenge of the domestic market to China's electronic measuring instruments; the second challenge is that the technical level of domestic and foreign products is very different, and China's electronic measuring instruments are in a very passive position.
Faced with such a grim situation, China's electronic measuring instrument industry is subject to the test, the second is to calmly think, and the third is to rise up and develop. Therefore, since 1978, China's electronic measuring instrument industry has entered a new development period different from the past. Its basic characteristics are: integration into the world and rapid development.
First, adjust the industrial structure. In order to survive and develop under the reform and opening up environment, many enterprises have developed electronic medical instruments and electronic application instruments based on electronic measuring instruments. This is not only the inevitable result of the country's strategy of "embring the army and the people", but also the only way for enterprises to seek survival and development.
Second, improve product quality. After 10 years of development, the MTBF of electronic instruments (that is, the mean time between failures, the full name of English is "Mean Time Between Failure", which is a measure of the reliability of a product) is generally more than 1000-2000 hours.
Third, improve the technical level of products. While electronic measuring instruments continue to expand exports, the export of electronic medical instruments in China is also expanding. In 1989, exports were about 10 million US dollars.
Fourth, through the introduction, digestion, absorption and localization work. After 10 years of development, the development capability and production technology level of electronic measuring instruments in China have been greatly improved.
Fifth, under the impetus of the reform and opening up situation, after more than 10 years of development, China's electronic measuring instruments have achieved a number of scientific research achievements, and won dozens of scientific and technological progress awards.
Relying on technological progress to promote industrial upgrading
With the development of China's new system electronic information system and new weapons and equipment, the occupation and utilization of limited spectrum resources has become an important feature of high-tech development and military electronic technology and equipment development, which fully utilizes the amplitude and frequency of electromagnetic waves in spectrum resources. Phase and polarization information is a core feature of modern electronic equipment.
Modulation domain testing technology is a new field of testing technology that emerged at the end of the 20th century. It has become the "three-domain" testing technology of the time with the time domain testing and frequency domain testing that we have known in the past. The time domain test measures the signal value of the input signal as a function of time and is the relationship between the signal amplitude and time. The frequency domain test is a measurement of the signal value of the input signal as a function of frequency, and is the relationship between the amplitude of the signal and the frequency. The modulation domain test measures the frequency value of the input signal as a function of time. The resulting display pattern represents the modulation domain of the signal and is the relationship between the frequency value of the signal and time.
A variety of digital TV test instruments have been provided for the successful development of digital TV in China. From 2008 to 2010, cable digital TV will be greatly developed. Digital TV testing is a complex system engineering, testing a variety of projects, including: cable digital television (DBC), satellite digital television (DBS), open circuit digital television (DMBT) RF signal, demodulated signal, code stream signal (TS), decoded signal (sound, video), etc.
China's self-developed TD-SCDMA mobile communication terminal comprehensive tester has been put into use. Mobile communication testing is a complex system engineering, from core chip testing, network system testing to terminal testing, which requires a variety of test instruments with high performance requirements.
In China's previous successful satellite launches, spacecraft and other major projects, China's electronic instrument companies from the digital multimeter, oscilloscope to microwave / millimeter wave measuring instruments provide high-level, high-quality dozens of varieties of hundreds Taiwan's electronic measuring instruments have played an important role in ensuring the smooth implementation of these major projects.
Driven by the reform and opening up situation, China's basic electronic measuring instruments are aimed at the international advanced level, and develop electronic measuring instruments with international intellectual property rights with international advanced level, which fill the gap in the domestic market and reach the international advanced level. Technical indicators of international advanced products.
Backbone enterprises emerged as the times require
Three types of companies in China's electronic measuring instrument industry are typically successful:
First of all, technology innovation enterprises. The 41st Research Institute of China Electronics Technology Group Corporation is a successful technology innovation enterprise. Over the past 30 years, 41 scientific research and production scales have been continuously expanded. It has two research and production bases in Yunnan and Qingdao, and has become a scientific and technological innovation research institute.
Second, brand-name entrepreneurial enterprises. Jiangsu Luyang Electronic Instrument Group Co., Ltd. is a successful brand-name entrepreneurial enterprise. Since the brand name effect of Luyang products has won many bids in domestic and foreign bidding, the economic benefits are in a leading position in the domestic electronic measuring instrument industry, and it is a successful brand-name entrepreneurial enterprise.
Once again, export entrepreneurial companies. Dalian Liaowu Er Electric Co., Ltd. is a typical export entrepreneurial enterprise. The company's total sales in 2006 was 236.66 million yuan, and the export value was 147.398 million yuan. The export volume accounted for 61% of the total sales. It ranks 85th among the top 100 information industries in China and is a successful export-oriented enterprise.
Only with the support of the state and society can we achieve development. “Associated economy” is not “scale economy”. Multi-variety, small-batch, multi-core technology, simultaneous or advanced other technologies and industrial development are its distinctive features. Therefore, supporting the development of the electronic measuring instrument industry, that is, supporting the development of the entire national economy industry, the preferential policies of other industries should be gradually radiated to the electronic measuring instrument industry.
Chinese enterprises should provide China's first-class electronic measuring instrument products with the spirit of self-improvement. It is necessary to cultivate first-class talents and master the core technologies for the development of electronic measuring instruments in the future.
