First, large-scale application of Fieldbus Foundation will gradually :
11 years [link widoczny dla zalogowanych], some of the world's major process automation vendors, organized and planned conduct of the Foundation Fieldbus technology, planning, research, trial [link widoczny dla zalogowanych], trial, and application in engineering practice, this is a system of unprecedented project, which has a large number of human wisdom, was appreciated by many people, especially by the "big customer" approval. Currently, FF 338 members have registered for the 227 kinds of products, by HIST interoperability testing and certification of main control system 11. Applications, 50 million field instruments, 8,000 sets of system has been applied, in which China accounted for 7%, about 80 sets of systems, mainly in the petrochemical and chemical, oil and gas, power generation in several industries, the Shanghai Secco, CNOOC / Shell Nanhai project may be the world's two major projects are in the number of major projects about to put into operation this year. These will play an exemplary role in China's large-scale applications. China also has great technical progress. Chinese Control, Shenyang Institute of Automation (in Cobo micro) and other units were developed and obtained registration of the product FF, has more than 10 kinds of professional book publishing. In particular, as several techniques have been initially popular: H1 communication theory; H1 function block configuration and the "Field Control" strategy; field equipment, auxiliary equipment and master control systems of choice; H1 network segment design and construction and installation; equipment Description Language (DDL) and interoperability. And for the enhanced EDDL and FISCO explosion of new technology such great passion, these are for future large-scale applications in China has laid a good foundation.
Present, China Instrument Industry Association Professional Committee of the fieldbus (CFFC) and 16 foreign diplomatic institutions of the Foundation Fieldbus Chinese Market Committee (FFCMC) are joint activities. Now FF is in the DCS is similar to the late 70s period in which, as a new technology to market road is hard. Through the pain, things will be like new born babies, as will thrive and grow up.
5 since April 12 ~ 14 FIA Fourth China International Fieldbus and Industrial Automation Instrumentation Exhibition (FIA) and June 14 to 17 in the ninth International Modern Factory / Process Automation Technology Equipment Exhibition (FA / PA) successfully held in Beijing, and held a number of major technology vendors exchange activities, the industrial automation market have become people attention, especially the "MM modern manufacturing," a special issue of the new automation, automation of proposed new The concept, that of industrial automation and mechatronics industry trends, it is worth our attention. I will only put forward the following few personal views, ideas of reference for active people.
Second, detection technology [link widoczny dla zalogowanych], identification technology and information fusion attention :
Sensor technology is in these years the conventional phase transition to the new sensor, which will be described in a separate post. Since only the boost fieldbus technology, digital instrumentation, intelligent, network has been a big step forward, especially in multi-variable transmitter of the successful listing, so that a differential pressure transmitter (such as Emerson 3015S and Yokogawa's EJX) can complete flow measurement and temperature and pressure compensation, flow accumulation, indicating the ball tank liquid volume, and for catheter blockage, steaming hot mix higher altitude and a series of diagnostic features, but also prepared to increase the wear plate detection capabilities This will enable device management can get more useful information. Digital field devices and networks into a wealth of information provides a smooth channel for more than a single signal to the information collected to create the conditions for change, coupled
