Inscription: in the recent CAS Shenyang Institute of Automation at the Chinese Academy of Engineering, "Industrial automation development," Engineering Science and Technology Forum, Zhejiang University, Industrial Automation National Engineering Research Center, Chinese Academy of Engineering Sun Youxian that my many large-scale equipment, such as large-scale integrated Machine tool Large Construction Machinery Large mining equipment, large-scale Metallurgy Equipment, large-scale Chemical industry Equipment, etc., have considerable manufacturing capabilities, but the lack of complete system with complete automation.

Results have been SUN Yin said, the equipment manufacturing industry especially major equipment manufacturers have their own distinctive characteristics: demand elasticity, a high degree of industrial relevance; development cycle long, will require substantial funding; sets strong need to work closely with all sectors; technically difficult, requires a variety of highly integrated high-tech; science and technology, economic growth has a strong leading role in national economic development, industrial restructuring is important. The complete automation system is an important component of large-scale equipment, there is no complete system automation, large-scale equipment would have no soul. Thus, the present development of large equipment must also complete the development of automation systems, which is key to the development of equipment manufacturing industry.

Recent years, China's industrial equipment has made great strides, for example, metallurgical equipment, China is capable of producing 1700 hot rolling, cold rolling 1780, 3500 and so has the plate rolling of hot and cold with the international advanced level rolling mill, continuous casting machines, and large cast end machine, 4063 m3 blast furnace, coke oven 6 meters, 200-ton large-scale open pit Equipment , And large coarse ALONE lead smelting furnace, smoking furnace, baking and so on.

Automation systems and equipment in metallurgy, Metallurgical Industry Automation Research Institute has been able to independently develop and complete large-scale hot strip mill control AC speed drive system technology, to capture the high-power AC-AC Inverter Design theory and manufacturing technology, alternating Inverter Hot rolling mill drive speed control and torsional vibration technology, hot rolling mill cycloconverter load eight observation and control technology, technical difficulties.

Major problem China's industrial automation systems low independent innovation ability, lack of independent intellectual property rights. Specifically expressed in the domestic high-end automation scarce, the market less competitive. At present, China-made high-end systems or complete private control optimization system is almost zero.

Most of our control system due to high reliability, high stability, high environmental adaptability, as well as digital, intelligent, integrated and so on, and there is a big gap between the foreign advanced products. Domestic control system into China's major projects critical equipment, core equipment, the main equipment is very difficult, most were dominated by foreign control. Performance gap, difficult access to major projects.

The same time control system "among strong, ends weak" a very serious problem. China-made equipment in the main control system, automation system, strong R & D, investment capital adequacy, technical achievements rich high quality. But as the control system at both ends??? Transducers and actuators, has long been a serious shortage of investment, R & D thin, poor product quality, design and manufacture our own smart transmitter in the domestic market share of foreign products is only One particularly smart actuators. And to miniaturization, digital, intelligent, integrated network into features, with high accuracy, high reliability, high adaptation targeted, small size, light weight, low cost, low power consumption compared to high-quality products , has a big gap.

Large-scale public works equipment, automatic control system is very backward. Large-scale public works equipment refers to large-scale construction machinery and equipment, large-scale mining machinery and equipment, large-scale port engineering equipment, large-scale traffic engineering equipment, engineering equipment and other large cities, a long time, insufficient capital investment, R & D is weak, the lack of modern control theory, methods, and technology integration.
