Intelligent into the future development trend of instrumentation

During the Eleventh Five-Year Plan period, China's instrumentation industry experienced a period of rapid development. However, entering the “Twelfth Five-Year Plan” and facing various uncertainties in the market, how to win market opportunities is a question that every company is pondering over. With the rapid development of microelectronics, computers, networks, and communication technologies and the continuous improvement of comprehensive automation, smart meters embody the requirements for intelligent, digital, and networked manufacturing, and will undoubtedly become an important direction for the future development of the instrumentation industry.

Market slowdown in instrumentation

In recent years, China's instrumentation industry has shown a trend of rapid development. According to the data released by the China Instrument Industry Association, during the “Eleventh Five-Year Plan” period, except for the impact of the global financial crisis, the growth rate in 2009 was only 8.9%, and the growth rate in other years was between 20% and 30%. . During this period, the increase in the global instrumentation market was only 3% to 4%. The rapid development of the instrumentation industry in China is evident. To sum up the reasons, it is inseparable from the economic development environment of our country:

First of all, the rapid development of China's economy has made China the world's largest emerging market. Global manufacturing has largely migrated to China, and a large number of foreign companies have begun to set up factories in China. This has created an unprecedented market demand for instrumentation products.

Second, China's new industrialization process, the deepening of the integration of the two, has led to the need for automation in various industrial fields, which has also brought prosperity to the instrumentation industry. The Chinese government has expanded the scale of the instrumentation industry to a certain extent by implementing a series of mandatory measures such as the implementation of energy-saving emission reduction targets and shutting down of outdated production capacity in major industries.

In addition, the implementation of national key projects, food safety, and pharmaceutical safety, which are related to national and people’s livelihood issues, provide opportunities for instrumentation that plays a crucial role in the intelligentization of manufacturing equipment, automation of production processes, and quality supervision and quarantine.

However, with the continuous deterioration of the international economic environment and the slowing down of China’s economic development, such as overcapacity in the iron and steel, cement, and glass industries, various problems have emerged in the areas of wind power, solar energy, rail transit, and food. The instrumentation industry also began to show a cooling trend. According to the latest data, from January to June 2012, the total industrial output value of the instrumentation industry in the country totaled 307.509 billion yuan, a year-on-year increase of 14.86%, and the sales value reached 290.936 billion yuan, a year-on-year increase of 14.94%. The slowdown in the growth of China's instrumentation industry has become apparent.

Smart meters become new highlights of the market

The rapid development of microcomputer technology and embedded systems has caused a fundamental change in the structure of instruments and meters, that is, taking the microcomputer as the main body, replacing the conventional electronic circuits of traditional instruments, and becoming a new generation of smart instruments with some intelligence. The design focus of this type of instrument has shifted from the design of analog and logic circuits to the design of dedicated microcomputer templates or microcomputer functional components, interface circuits, and input/output channels, as well as the development of application software. The various functions of the traditional analog meter are realized by the unit circuit, while in the meter with the single chip microcomputer or the embedded system as the main body, the programming software, various special and complicated function modules, and the simplified user configuration programming function And various typical application control strategy packages and other modules of software to complete numerous data processing and control tasks. This kind of meter has already realized some functions of the human brain, such as four operations, logic judgments, command recognition, etc. Some of them can also perform self-correction, self-diagnosis, and have the ability of self-adaptation and self-learning. meter".

From the perspective of the development trend of instrumentation technology, the intelligentization of instrumentation is an irreversible trend in the development of instrumentation. The application of digital technology in instrumentation has not only improved the performance and accuracy of the instrumentation, but has also been accompanied by the advent of fieldbus. , for the upgrading of instrumentation, product upgrades and to achieve further high-precision, high-performance, especially multi-parameter on-line real-time monitoring and automatic measurement and control, high stability, high reliability, high adaptability, multi-function, low consumption, etc. provide a huge Power and development space make information exchange of smart instruments faster, and pre-diagnosis, pre-maintenance and other functions become a reality.

As one of the intelligent instruments, smart meters are no longer a simple hardware entity but a combination of hardware and software. In recent years, smart meters have begun to develop from more mature data processing to knowledge processing, and their functions have been developed to a higher level.
