1, the development of industrial control machine and "fifteen" goal
To promote industrialization through informatization and upgrade of traditional industries with high and new technologies is a major policy of our country. Since 1983, industrial control computer included in the national computer series type spectrum and development planning, with the strong support of the country through the joint efforts of the IPC workers, the rapid development of China's industrial computer business in industrial control machine development and Industrialization and promotion have made great strides. Many industrial control technologies and products are mature and have been successfully applied in various fields. Some of them have been able to compete with foreign or overseas products, especially in DCS, IPC and some embedded control devices.
Hollysys, Zhejiang University of Technology, Xinhua, VIA and other companies of the DCS series of products have entered many large projects, and even exported abroad, according to chemical industry statistics, domestic DCS has accounted for about 50% of the market share; EVOC and other units IPC products Sheng Bo's embedded products have entered the international market, as Siemens, Alstom and other European companies supporting products; aerospace monitoring and control company's VXI, PXI products have become the focus of national defense industry ground measurement and control products; Connaught's A new generation of CompactPCI series products have been successfully developed. In addition, in the past two years, there have been new faces of foreign counterparts in the domestic market. In Taiwan's counterparts in China, apart from Advantech and Panzhi, CompactPCI, PXI series products appear in the mainland market; in the field of R & D and application of the bus, there are also great progress in China, FF, Profibus, LonWorks, CAN, etc. have many successful examples of successful applications, industrial Ethernet Great progress has been made; the development and application of industrial control software also have good results.
In recent years, the international FCS, DCS, PLC, IPC, NC and various types of embedded control devices are in rapid development, and our country's development speed ranks among the highest in the world. According to statistics, in 2000, the industrial control computer market in the world reached 30-40 billion U.S. dollars and grew at a rate of 10-15% annually. In the same period, the market size of industrial control computers in China was about 20 billion yuan.
In the Tenth Five-Year Plan for Information Industry, the industrial control machine industry will reach an annual output value of 100 billion yuan. The key points of development are: adapt to the demand of transforming traditional industries, vigorously promote the industrialized production of PLCs and embedded industrial computers, and focus on the development and production of DCSs and FCSs with independent intellectual property rights, bringing the domestic brands to more than 50% market share. In the "Tenth Five-Year Plan" period of the instruments and meters of the State Economic and Trade Commission, the corresponding goals have been put forward in the fields of electric power, metallurgy, petrochemical, environmental protection, transportation and construction. The demand for IPC is very great and the market is very vast.
During the period of "the Tenth Five-Year Plan", the automation main control system in our country will still be dominated by DCS and IPC. The situation of large-scale DCS based on foreign products will not change much in the near future. PLC and IPC-based DCS and industrial control devices are used in small and medium-sized projects Application will dominate.
2, three major changes in industrial control system
Automation technology is undergoing major changes, and our work is essentially centered around such changes. The main aspects are: fieldbus and fieldbus control system FCS; PC-based industrial control computer; integrated management and control system integration technology.
2.1 About FCS
Due to the development of fieldbus technology, a new generation of fieldbus control system FCS is moving towards practicality, which is an important hot point of automation technology. It will bring a profound revolution to automation technology. The key points of FCS are as follows: FCS is based on digital intelligent field devices; the core of FCS is the field bus protocol, that is, the bus standard; the essence of FCS is the on-site and networked information processing. FCS is developed from two aspects, one PLC, the second is DCS. After the practical application of FCS, it will inevitably affect the prospects of PLC and DCS. According to experts, FCS will gradually integrate with DCS and FCS will eventually replace DCS. However, there will be a long historical process; and PLC will have a long history Control has a unique advantage, as a station c? In the fieldbus can give full play to the advantage of PLC in the treatment of switch, so in the future will be able to follow the fieldbus communication protocol PLC or PLC can exchange information with the FCS Preferred object.
2.2 About IPC
Since its entry into industrial automation in the early 1990s, industrial PCs have been unstoppable in various fields and have been widely used. The reason is that the PC is open, it has a wealth of hardware resources, software resources and human resources, that is, the majority of engineering and technical personnel support, but also for the general population are familiar with, this is the basis of IPC heat. PC-based (including embedded PC) control system is growing at more than 20%, far beyond the DCS, PLC. It is noteworthy that the major PLC manufacturers have accepted the IPC's technical route, PLC has IPC trend. Not only that, DCS, NC also have the trend of IPC. PC-based control technology will become one of the mainstream technologies in the automation world at the beginning of this century. In the future for a long period of time, FCS, DCS, PLC, IPC, NC will complement each other and promote each other, but the advantages of IPC will be more prominent, its application will rapidly expand to all areas of automation.
Expected by 2005, PC-based industrial control machine will account for more than 50% market share. IPC market in our country (including embedded controller ) is very active, and the same as the international market, IPC is also the fastest growth rate, this is because IPC can provide a very rich open hardware and software platform, low price and easy with other information technology integrated. There are a lot of IPC manufacturers in China, mainly including EVOC, Advantech, ADLINK, Xunyi, Contotek, Kangtuo, etc. In the categories of FCS, DCS, PLC, IPC and NC, the localization of IPC is the highest, Estimated before long, and PC, IPC will be mainly dominated by domestic products, especially the mainland product world.
2.3 management and control integration system integration system and software With the Internet technology into the enterprise management and control among the combination of control system and management system become inevitable, which makes the industry automation industry long-eager integration of management, industrial enterprise information, The goal of web-based automation becomes possible. The integration of management and control can enable enterprises to choose the best solution that truly meets the new economic era so as to enhance their production efficiency and enhance their market competitiveness. This must be the integration of management and control systems integration technology and systems development. As a result, automation technology has entered a new era in the direction of open, distributed, intelligent systems over Ethernet and Web technologies, based on the technical standards for Ethernet and TCP / IP protocols, providing modular, distributed and reusable Automation program. Among them, the main area is the development of web-based engineering industrial control and management software.
