Abstract: Compared with the products and technologies of developed countries, the gap between domestic technical indicators and foreign similar products is not large, but there is a big gap between the reliability and stability of domestic instruments and foreign products. The experience of industrialized countries shows that if we want to open the international market and win in the market competition, we must first improve the reliability of the product. The United States believes that the core of product quality is reliability, and reliability can create miracles. Therefore, experts propose to build a national-level "public service platform for the reliability development of instrumentation products" to enhance the ability of scientific and technological innovation of enterprises, promote industrial technological progress, and solidify the basis for industrial development.
The “Xianmen Gate†incident highlights the obstacles to instrument development One of the major problems in the quality of instrumentation products is the problem of product life and environmental adaptability, that is, reliability issues. How to improve the reliability of instrumentation products has become an imperative for the instrumentation industry.
In January 2010, the Hainan Provincial Administration for Industry and Commerce released the latest investigation result of “Xinhuangmenâ€, which is mainly due to technical reasons that caused the first inspection error, saying that the instrument is aging and unstable and results in deviations in the test results. This survey result once again puts the reliability and stability of instrumentation products to the forefront.
Experts believe that the reliability and stability of domestic instrumentation and automation systems are very different from those of foreign products. Its reliability issues have shaken the confidence of key industries such as metallurgy, electric power, and petrochemical industries in domestic products. As a result, localization of instrumentation and automation systems has been the slowest in the nationalization of major national technical equipment. Greatly affected the improvement of equipment manufacturing technology and product quality.
Stability and reliability issues have become a serious obstacle to the development of China's instrumentation industry and technological innovation.
Compared with products and technologies from developed countries, the gap between domestic technical indicators and similar foreign products is not large, but there is a big gap between the reliability and stability of domestic instruments and foreign products. The warranty period for many foreign products after delivery has been extended to 5 or 10 years, and even the concept of lifetime warranty and invisible instruments has been proposed. Most of the national instruments are still at the level of one year warranty.
The reliability of instrumentation and stability issues have not only attracted the attention of entrepreneurs, scientists are also very concerned and anxious about this. Qian Xuesen believes that reliability is designed, reliability is produced, and reliability is managed.
Zhang Zhonghua, academician of the Chinese Academy of Engineering and chief researcher of the China Academy of Sciences, believes that the future technological development of instruments and meters should focus on the two areas of product structure and product reliability technology to accelerate construction, so as to meet the needs of various industries and improve the efficiency of users.
Development Status and Trends of Domestic Reliability Development After half a century of development, reliability research and application have become an engineering science discipline covering all disciplines and industries. From the reliability development of electronic products to the reliability of mechanical and non-electronic products. From the development of the reliability of hardware to the reliability of software, from the emphasis on the development of reliability statistical tests to the emphasis on reliability engineering tests, through the environmental stress screening and reliability enhancement tests to expose product failures and improve product reliability.
According to Professor Shi Zhenshan of the Institute of Instrument Technology and Comprehensive Technology of the Machinery Industry, in actual use, the user's response is mainly due to the stability and reliability of the product. Reliability research and application has a long history and glorious tradition in the instrumentation industry.
In 1981, the former State Administration of Instrumentation Industry proposed an exploratory experimental study of a DDZ-2 type temperature transmitter and regulator as a typical case, carried out a reliability assessment test, and explored methods, approaches, and effects of reliability application. Through improvement, the reliability index of the temperature transmitter has increased by 1.6 times and the regulator has increased by 2.9 times.
From 1986 to 1991, the former Ministry of Machinery Industry issued a notice of “Measurement of instrument and meter deadline assessment reliability indicatorsâ€, and included more than 200 products in 11 specialties of instrumentation into the scope of departmental assessment. Through this stage of practice, a series of technical documents such as instrument reliability methods, working procedures, technical specifications, etc. have been created, which has created conditions for carrying out reliability studies, tests and assessments.
In the 1990s, instrumentation and metering mainly took the approach of introducing, digesting, and attracting innovation, focusing on the introduction of manufacturing technology and no product design technology, resulting in a weak sense of reliability. In addition, the reliability practices implemented in the era of planned economy have become obsolete, and new reliability concepts, methods, and tools at home and abroad have developed rapidly. As a result, the narrowing gap with foreign countries has rapidly widened.
In 2008, Wen Jiabao’s article “Discussing the in-depth implementation of the Scientific Outlook on Development†pointed out that at present the development of the equipment manufacturing industry is lagging behind, the product reliability is poor, and the problem of complete sets of capabilities is very prominent. It is necessary to change this situation as soon as possible, improve the R&D and design capabilities, manufacturing capabilities, and integration capabilities of major equipment, develop equipment required for major complete sets of equipment, high-tech equipment, and high-tech industries, and promote the green, information, and localization of equipment manufacturing.
In September 2008, the China Instrument Management Society unanimously passed the "Recommendation on the establishment of a national laboratory for reliability of instrumentation." It is believed that the reliability of instrumentation and instrumentation is in great need of government policy guidance and strong support.
Experts: Building reliability Development of public service platforms With the increase of intelligence, automation, miniaturization, and networking, the structure of instrumentation and equipment is becoming more complicated, the scale of the system is getting bigger, and the possibility of failure is greater. The more urgent the need for reliability technology is. With the rapid construction and development of smart grids and the Internet of Things, as well as energy-saving and emission-reduction requirements, it is expected that in the “Twelfth Five-Year Plan†period, various industries will refer to the national agenda for reliability planning.
In September 2010, the “12th Five-Year Plan for Reliability of Shenzhen Power Grid†passed the review. This is the first city-level “Twelfth Five-Year Plan†reliability plan in China. The plan creatively proposes a reliability planning method based on the logical framework method, realizes the current grid reliability assessment and planning grid reliability prediction function, and can accurately calculate the impact of the relevant variables on the reliability index, and provides for China's reliability planning. New methods and ideas.
The experience of industrialized countries shows that if we want to open the international market and win in the market competition, we must first improve the reliability of the product. The United States believes that the core of product quality is reliability, and reliability can create miracles.
In view of the fact that domestic instruments have many varieties and small batches and there are no characteristics of large enterprises with particularly strong strength in the industry, experts propose to build a national-level "public service platform for reliability development of instrumentation products" in order to enhance the ability of scientific and technological innovation of enterprises and promote the industry. Technological progress has strengthened the foundation for industrial development. The platform focuses on the research and development of the reliability common technologies of key instruments and automation systems and the reliability technologies of key products.
