Objective:

"The tiger to Granville in rabbit to transport more prosperous." "Eleven five"development has a wonderful ending, "Twelfth Five Year" development is the headstart. The Central Committee of the party to map out the grand blueprint for the"Twelfth Five Year Plan" to inspire us to forge ahead of the force, the scientific development shows broad prospects, make us confident. 2011 is the "Twelfth Five Year Plan" period of the first year, more is a year of hope, the struggle of the year,ahead of the year, a new magnificent picture will thus unfold.

The prospect of "Twelfth Five Year Plan", the industrial automation Chinese have entered the twenty-first Century, the rapid development of China's manufacturing industry, pulling on Automation Instrument and control system to the development ofthe international level of demand, large new projects in China with advancedautomation instrumentation and control system of the demand has been in the advanced world level. Current our country is in the middle stage of industrialization.Industrialization, informatization, modernization, marketization and internationalizationis closely related to the "five". Informatization and industrialization will have good prospects for development, enterprises should pay attention to the new requirements,the country put forward the industrialization of the integrated, producer services, such as energy-saving emission reduction may be new technology growth, pay attention tothe new trend of the software technology, may also need new thinking (cross,intelligent space based, etc.). At the same time, saving energy and reducing consumption is still the "Twelfth Five Year Plan" period of the key problems, these problems, we have to use the "Twelfth Five Year Plan" for the vision and wisdom totake seriously. In the promotion of automation technology, the industry is moving towards digital, intelligent, networked and integrated in the direction of development,manufacturing factory is evolving towards high integration, integration processforward. But the future, along with the means for people to the application of high-endautomation technology more and more mature, we can see more likely to happen!

The trend is the people's friend, as you recognize the road ahead. This article is from the trend point of view to explore the popular technology of automation industry at present, in order to give the reader some development information.

According to the analysis, industrial automation is the current hot technology:

One, intelligent instrument

In the control system, instrument and meter as its constituent elements, technologyprogress in its development and development following control system. At pr. At present, control theory has developed to a new stage of intelligent control, intelligentautomation instrumentation has become inevitable. Development and application ofintelligent instrument is mainly due to the microprocessor and artificial intelligence technology. For example, the use of neural network, genetic algorithm, evolutionary computation, the chaos control of intelligent technology, the instrument to realize high speed, high efficiency, multifunction, high flexibility performance. Moreover, the use offuzzy reasoning of fuzzy rules, all kinds of things fuzzy relation of various types of fuzzydecision. As another example, the realization of signal filtering software, such as thefast Fu Liye transform, short-time Fu Liye transform, wavelet technology, is to simplify the hardware, improve the signal-to-noise ratio, the effective way to improve the dynamic characteristics of sensor; also like, make full use of the artificial neural network technology strong self-learning, adaptive, self-organizing ability, association,memory function and the complex nonlinear relationship between input, output of the black box mapping characteristics.

At present, the field of intelligent Chinese most weak, most in need of development is the instrument, meter, sensor and other basic industries. With the rapid development of science technology and automation degree enhances unceasingly, instrumentation industry in China will also be a new change and obtain new development.Instrumentation products with advanced technology, especially the intelligent, will become the future development of the mainstream of Instrument Science and technology and industry. Based on intelligent instrument intelligent control theorybased at roughly the progress of the following aspects:

- expert controller

Expert control system (expert control system, ECS) is a typical control system based on knowledge, it is a specialized knowledge and abundant experience of proceduresystem. It is the use of artificial intelligence technology and the computer technology,according to one or more experts in a field to provide experience and knowledge,reasoning and judgment, simulate the decision process of human experts, to solve complex problems that need a human expert to solve good.
