The electronic measuring instrument industry has been highly valued by the country since the founding of New China. During the "First Five-Year Plan" and the "Second Five-Year Plan", electronic measuring instruments accounted for 12 of the 156 major national projects built at that time, accounting for 7.7% of the total national major projects. By the end of the second five-year plan, 11 factories and 1 research institute with the international advanced level at that time were basically completed, laying a preliminary foundation for the development of my country'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 technological progress. Whether from an economic perspective, an industrial perspective, a national security perspective, or a technological advancement perspective, we can see the inseparable relationship between electronic measuring instruments and the electronic measuring instrument industry.

Electronic measuring instruments are based on circuit technology and integrate electronic test and measurement technology, computer technology, communication technology, digital technology, software technology, bus technology, etc. to form a stand-alone 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 measured system. Electronic measuring instruments are used in all fields of the national economy in an all-round way, which is an indispensable condition for realizing national scientific and technological progress and original technology.

Electronic measuring instruments should be synchronized with or ahead of other high-tech developments. It is a fusion of various high-techs and supports the development of various high-techs. Upgrade the product structure to effectively increase the domestic market share. Electronic measuring instruments are related to the economy and strategic industries. The electronic measuring instruments of economically developed countries in the world generally account for 4% of the GDP, but they have a pulling force of 66% of the GDP, and are related to the national economy. Up to more than 90%. The electronic measuring instrument industry is the embodiment 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 middle and low-end products, and the products were imitated. In scientific research and development work, the backbone enterprises are the leading enterprises to develop new products according to the product category division, and the products of the backbone enterprises represent the level of the industry category products. 1978 and before was the period for my country to strengthen national defense construction. Therefore, the technological development of electronic measuring instruments is closely focused on the needs of national defense. From technical indicators, measurement functions to working environment, they must adapt to the requirements of war. Thus, the solid state of electronic measuring instruments is proposed. The development direction of integration, integration and reliability.

The reform and opening up make our country's electronic measuring instrument industry face the new situation of challenge and development first. The "challenge" mainly comes from two aspects: one is the serious challenge of the domestic market to our country's electronic measuring instruments; the second challenge is that the technical level of domestic and foreign products is very different, and our country's electronic measuring instruments are in a very passive position.

Faced with such a severe situation, my country's electronic measuring instrument industry is first to withstand the test, the second is to think calmly, and the third is to rise up and develop. Therefore, since 1978, my country's electronic measuring instrument industry has entered a new period of development that is different from the past. Its basic characteristics are: integration into the world and rapid development.

industrial restructuring. In order to survive and develop in the environment of reform and opening up, many companies have developed electronic medical instruments and electronic application instruments on the basis of electronic measuring instruments. This is not only the inevitable result of the country's strategy of "combining the army with 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 (mean time between failures, the full English name is "MeanTimeBetweenFailure", which is a measure of the reliability of a product) of electronic instruments is generally above 1000-2000 hours.

Third, improve the technical level of products. While the export of electronic measuring instruments continues to expand, the export of electronic medical instruments in my country is also expanding. In 1989, the export value was about 10 million U.S. dollars.

Fourth, through the introduction, digestion, absorption and localization work. After 10 years of development, my country's development capability and production technology level of electronic measuring instruments have been greatly improved.

Fifth, driven by the reform and opening up situation, after more than 10 years of development, my country's electronic measuring instruments have achieved a number of scientific research results and won dozens of scientific and technological progress awards.

Relying on technological progress to promote industrial upgrading

With the development of my country’s new electronic information systems and new weapons and equipment, the occupation and use of limited spectrum resources has become an important feature of the development of high-tech and military electronic technology and equipment, in which the electromagnetic wave amplitude and frequency in the spectrum resources are fully utilized. , Phase and polarization information are the characteristics of modern electronic equipment.

Modulation domain testing technology is a new testing technology field that emerged at the end of the 20th century. It has become the "three-domain" testing technology at the time as well as time-domain testing and frequency-domain testing that we are familiar with in the past. Time domain test is to measure the signal value of the input signal that changes with time, and it is the relationship between signal amplitude and time. The frequency domain test is to measure the signal value of the input signal changing with the frequency, and it is the relationship between the signal amplitude and the frequency. Modulation domain test is to measure the frequency value of the input signal changing with time. The generated display figure represents the modulation domain of the signal, and is the relationship between the frequency value of the signal and time.

Provided a variety of digital TV test instruments for the successful development of my country's digital TV. From 2008 to 2010, cable digital TV will be developed by leaps and bounds. The test of digital TV is a complex system engineering, and there are many test items, including: digital cable TV (DBC), satellite digital TV (DBS), open-circuit digital TV (DMBT) radio frequency signal, demodulation signal, code stream signal (TS), decoded signal (audio, video), etc.

The TD-SCDMA mobile communication terminal comprehensive tester successfully developed by my country has been put into use. Mobile communication testing is a complex system engineering. From chip testing, network system testing to terminal testing, a variety of test instruments with high special performance requirements are required.

In my country’s previous successful satellite launches and spacecraft missions to the sky, my country’s electronic instrument companies have provided high-level, high-quality dozens of varieties, from digital multimeters, oscilloscopes to microwave/millimeter wave measuring instruments. A set of electronic measuring instruments played an important role in ensuring the smooth implementation of these major projects.

Driven by the situation of reform and opening up, my country’s basic electronic measuring instruments aim at the international advanced level, and develop electronic measuring instruments with independent intellectual property rights that have the international advanced level, filling the gaps in the domestic market, reaching the international advanced level, and surpassing the current similar Technical indicators of internationally advanced products.

In 2006, the company's total sales were 2306.6 million yuan, and the export value was 147398 million yuan. The export value accounted for 61% of the total sales. It ranked 85th among the top 100 information industries in China.

Development can only be achieved with the support of the state and society. "Related economy" is not "economies of scale". Multi-variety, small-batch, multi-technology, synchronization or advancement of other technologies and industrial development are its salient features. Therefore, to support the development of the electronic measuring instrument industry, that is, to support the development of the entire national economic industry, the preferential policies of other industries should gradually radiate to the electronic measuring instrument industry.

Chinese enterprises should provide our country with world-class electronic measuring instrument products with the spirit of self-improvement. It is necessary to train first-class talents, but also to master the development of electronic measuring instrument technology for a period of time in the future.
