Industrial automation equipment technology and production process
With the development of national economy, the improvement of people's living standards, the need of electricity is in constant increase, the power equipment also increased accordingly, grid structure and operation mode is becoming more and more complex, people also more and more high to the requirement of power quality. In order to ensure the user's electricity, the power grid must be managed and controlled.
The task of running management and scheduling of power systems is complex, but in simple terms:
(1), as far as possible to maintain the normal operation of the power system, safety is the top priority of power system, the system in the event of accident, the harm is difficult to estimate, therefore, strive to maintain the normal operation of the power system is the primary task;
The three parameters that reflect the quality of power are voltage, frequency and waveform. These three parameters must be within the specified range to ensure the quality of the electricity. The key to stable voltage is the balance of reactive power in the regulating system, frequency
Industrial automation industry automation
The change is the balance of the active power of the whole system. The waveform is determined by the generator.
To ensure the economy of power system operation, to make the most economical.
Power system is a system with wide distribution, large amount of equipment and multiple information parameters. The power plant can send the power supply to the user, and it must be transmitted by several transformer transformer. Voltages at all levels supply power to users through transmission lines, voltage from low to high, and from high to low, to facilitate the transmission of energy. The transformation of voltage, forming different voltage levels and forming substations of different voltage levels, and the transmission lines between substations, thus form a complex power grid topology. Grid scheduling is managed and scheduled according to the topology of the power grid.
In general, the power grid sets the dispatch center according to the voltage level. The higher the voltage level, the higher the dispatch center. The whole system is a pagoda-type network diagram. Hierarchical scheduling can simplify the topology of the network, make the transmission of information more reasonable, thus save communication equipment greatly, and improve the stability of system operation. According to the situation of China, the power system scheduling is divided into the national dispatch center, the regional control center of the regional network, the provincial control center, the regional dispatch control center, and the county dispatch center. Direct management and dispatching of the next layer of dispatch center at all levels.
Power grid scheduling
Power grid dispatching automation is a general, because the task of dispatching center at all levels is different, the size of the dispatching automation system is also different, but no matter which level of dispatching automation system, is one of the most basic functions, is the Supervisory Control And Data collection system, also known as function of SCADA system (Supervisory Control And Data Acquisition).
SCADA mainly includes the following functions:
Data collection; Information display; (I) surveillance control; Handle alarm processing; Information storage and reporting sequence of events; Data calculation of the data; It has RTU (remote terminal unit) processing function; The function of remembrance event recall.
AGC function: automatic generation control AGC system is mainly required for how many is not directly controlled by power plant generators, but by the power plant of the superior dispatching center based on the principle of global optimization for control.
EDC (Economic Dispatch Control) : the purpose of EDC is to Control the power distribution of various generators in the power system so as to minimize the operation cost of the power grid. The EDC is often included in the AGC.
Security Analyze function: SA function is the grid scheduling
The function of "nip in the bud" and be equipped. It analyzes the current state of the current power grid through the computer, estimates the possible failure, takes measures in advance to avoid accidents. If the power grid dispatching automation System has the function of SCADA + AGC/EDC + SA, it is called the EMS of Energy Management System. Digital transmission technology and the increase of the optical fiber communication technology, make the power grid dispatching automation has entered the network, now most of the computer configuration of power grid dispatching adopted the development of distributed computer system. With the development of China's national economy, China has also entered the era of big power grids, large units and ultra-high voltage transmission. It can be believed that with the development of China's new power grid automation system, the automation level of China's power grid dispatch will be further improved to reach the advanced level of the world.

Flexible manufacturing
Introduction to the
Flexible manufacturing technology (FMS) is the summation of all kinds of technology of programmed flexible manufacturing process for various shape processing objects. Flexible manufacturing technology is a technology-intensive technology group, and the processing technology that focuses on flexibility and ADAPTS to multiple varieties, small and medium-sized batches (including single products) belongs to flexible manufacturing technology.
Flexibility can be expressed in two ways. The first part is the ability of the system to adapt to the change of external environment. The system can meet the requirements of new products. The second aspect is the ability to adapt to changes in internal system, available in interference (such as machine malfunction) cases, the productivity of the system and the ratio of the expected value of productivity without interference can be used to measure the flexible. "
Flexible is relative to the case of "rigidity", "traditional" rigid "of automation product line is mainly a single variety of mass production. Its advantage is that productivity is high, because the device is fixed, so the equipment utilization rate is also high, single product cost is low. But the price is quite expensive, and can only process one or several similar parts. If you want to obtain other varieties of products, it must be to adjustment of the structure, the elements for reconfiguration system, its workload and fund input and construct a new production line often. Rigid mass manufacturing automation product line is only for a few varieties of products, it is difficult to deal with many kinds of medium and small batch production. Along with the social progress and improvement of living standards, more market demand characteristic, conform to the requirements of the customers' personal styles and functions of different products. The fierce market competition forces the traditional mass production mode change, requirements for the parts of the traditional production process is improved. The traditional manufacturing system can not meet the market demand for more varieties of small batch products, which makes the system more and more important. The flexibility of the system of survival with the mass production time is gradually replaced by the dynamic production to adapt to the market, a survival ability and competition ability of manufacturing automation system depends largely on whether it can in a very short development cycle, produced with lower cost and higher quality of different varieties of products. The flexible has been occupies an important position.
classification
When the machine is required to produce a series of different types of products, the machine can process different parts with the product changes.
The process flexibility is the ability to adapt to the change of products or raw materials when the process is invariable; The second is the degree to which the manufacturing system changes the corresponding process in order to adapt to the change of the product or the raw material.
Product flexibility is the ability of the system to produce new products very economically and rapidly after the product is updated or completely changed. Second, after the product is updated, the inheriting ability and compatibility ability of the old products are useful.
Maintain flexible use
Industrial automation industry automation
The ability to query and handle faults in a variety of ways to ensure normal production.
Flexible production capacity of production capacity change, the system can also operate economically. This is especially important for the manufacturing systems that are organized and produced according to order.
It can easily extend the system structure and increase the modules to form a larger system when the production needs.
Flexible use of different machines, materials and process processes to produce a range of products and the same products for different processes.
Flexible manufacturing system
There is a computer integrated management and control system for the efficient manufacturing of small and medium bulk variety of components. It has:
Multiple standard manufacturing units, CNC machine tools with automatic upper and lower feeding functions;
A set of material storage and transportation system can be used to transport workpieces and tools between the clamping stations of the machine tool. FMS is a programmable manufacturing system which contains automatic material conveying equipment which can realize information integration and logistics integration with the support of the computer
A variety of parts that can be processed with similar features and processes;
Automatic replacement of knives and workpieces;
Easy access to the Internet, easy to integrate with other systems;
When dynamic scheduling and local failure can be carried out, the logistics path can be reorganized dynamically.
The FMS scale tends to be small, low cost, and becomes FMC. It may only have one processing center, but it has independent automatic processing power. Some FMC have the function of automatic transmission and monitoring and management. Some FMC can not operate for 24 hours. The FMS used for equipment is called the flexible equipment system (FAS).
Intelligent manufacturing
Introduction to the
Intelligent Manufacturing, Intelligent Manufacturing, IM) is a kind of Intelligent machine and human experts composed of Intelligent man-machine integration system, it can intelligence activities in the Manufacturing process, such as analysis, reasoning, judgment, and ideas. And decision making, etc. Working with intelligent machines to expand, extend, and partially replace the mental work of human experts in the manufacturing process. It updates the concept of manufacturing automation to flexible, intelligent and highly integrated.
When it comes to intelligent manufacturing, we should first introduce the research plan of international cooperation of intelligent manufacturing system IMS, which Japan initiated in April 1990. Many developed countries, such as the United States, the European Community, Canada and Australia, participated in the project. The program plans to invest $1 billion to implement early-stage research programs for 100 projects.
There is no doubt that intelligence is the development direction of automation. Artificial intelligence technology is widely used in all aspects of manufacturing processes. Expert system technology can be used in engineering design, process design, production scheduling, fault diagnosis, etc. It is also possible to apply advanced computer intelligent methods such as neural network and fuzzy control technology to product formulation, production scheduling and so on. Artificial intelligence is especially suitable for solving particularly complex and uncertain problems. But it's also clear that the whole process of making things smarter, if not completely impossible, is at least in the distant future. Some even ask this question, the next
Industrial automation industry automation
Will discipline realize intelligent automation? This intelligence is limited if only a local mitigation of the enterprise is intelligent, and the global optimization is not guaranteed.
Understanding from the broad concept, CIMS (computer integrated manufacturing system), agile manufacturing and so on can be seen as examples of intelligent automation. Indeed, in addition to manufacturing process itself can implement intelligent, can also gradually realize intelligent design, intelligent management, etc., and information integration, global optimization, and gradually improve the intelligent level of the system, eventually establish intelligent manufacturing system. This could be a viable way to achieve intelligent manufacturing.
multi-agent
Agent is the Agent, which refers to the party authorized to represent the client in commodity economy activities. Later, it was borrowed into fields such as artificial intelligence and computer science to describe the intelligent behavior of computer software, known as the smart body. In 1992, there were predictions that "Agent based computing could be a major breakthrough in the next generation of software development." As artificial intelligence and computer technology is widely used in manufacturing, multi-agent system technology to deal with product design, manufacturing and product throughout the life cycle of coordination and cooperation in various fields of provides a method of intelligent also designed for the system integration, parallel, and intelligent manufacturing provides a more effective means.
The subsystem
The basic component of the whole subsystem is the whole child (Holon). Holon borrowed from Greek, and people use Holon to represent the smallest components of the system, and the whole subsystem is made up of many different kinds of whole children. The most essential characteristic of the whole child is:
Low autonomy, each child can plan for its own operation behavior, to an accident (such as manufacturing resources, goods manufacturing task requirements changes, etc.) to react, and its behavior under control;
Cooperative, each individual can request other whole children to perform some kind of operation behavior, also can be right
Industrial automation industry automation
Other operations application provided by the whole child;
Intelligent, the whole son has reasoning, judgment and other intelligence, which is also the internal cause of its autonomy and cooperation. The above characteristics of the whole child show that it is similar to the concept of intelligent body. Because of the totipotency of the whole child, it is also translated into the universal system.
The characteristics of the whole subsystem are:
Agility, self-organizing ability, can quickly and reliably form a new system.
Flexible, there is a strong adaptability to rapidly changing market and changing manufacturing requirements. In addition, there are biological manufacturing, green manufacturing, fractal manufacturing and other modes. Manufacturing model mainly reflects the development of management science, technology and automation, system research, it will put forward the new subject of various unit automation technology, which affect on the overall development direction of manufacturing automation. Looking ahead, 21st century manufacturing automation will continue along the track of history. [3]
Hot technology
Industrial control automation technology is a kind of control theory, instruments and meters, computer and other information technology, realize detection, control and optimize the process of industrial production, scheduling, management and decision-making, to increase production, improve quality, reduce costs, ensure safety of comprehensive technology, mainly including industrial automation software, hardware and system three parts. As one of the most important technologies in modern manufacturing in the 20th century, industrial control automation technology mainly solves the problem of production efficiency and consistency. Although the automation system itself does not directly create benefits, it has a significant effect on the enterprise production process.
The development path of China's industrial control automation is mainly absorbed by the introduction of complete sets of equipment, and then the secondary development and application. China's industrial control automation technology, industry and application have developed a great deal, the industrial computer system industry in China has been formed. Industrial control automation technology is developing towards intellectualization, network and integration.
The automation of low-cost industrial control based on the industrial PC will become mainstream
As is known to all, starting in the 1960 s, the western countries are relying on technology progress (that is, the new equipment, new technology, and computer applications) on modification of traditional industries, make industry gets rapid development. The world's biggest change in the late 20th century was the formation of global markets. Global markets led to unprecedented fierce competition, enterprises must speed up new product on the Market Time (Time to Market), the improvement of Quality (Quality) and Cost (Cost) and improve the Service system (Service), which is enterprise T.Q.C.S.. Although computer integrated manufacturing system (CIMS) in combination with information integration and system integration, the pursuit of more perfect T.Q.C.S., make the enterprise to realize "at the right time, to the right information in the right way to the right people, in order to make the right decisions", "five right". However, this kind of automation requires a large amount of capital, which is a high investment, high efficiency and high risk development mode, which is difficult for most small and medium-sized enterprises to adopt. In China, small and medium-sized enterprises, as well as quasi-large enterprises, are the path of low-cost industrial control automation.
Industrial control automation mainly consists of three levels, from the bottom up to basic automation, process automation and management automation, whose core is basic automation and process automation.
The traditional automatic system, basic automation some basic monopoly by PLC and DCS, process automation and management automation part is mainly composed of various kinds of imported process computers or small, the price of its hardware, system software and application software of high to many businesses.
Since the 1990 s, because of the PC - -based industrial computer (hereinafter referred to as industrial PC) development, the industrial PC, I/O device, monitoring device, control network composed of PC - -based automation system has been spreading quickly and become an important way to implement low cost industrial automation.
With pc-based controller proved reliable can like PLC, and accepted by the operation and maintenance personnel, so, one by one of the manufacturers, at least in part of PC control scheme is adopted in production. The PC based control system is easy to install and use, and has advanced diagnostic functions. It provides a more flexible choice for system integrators. In the long term, the maintenance cost of PC control system is low. Because PLC is the most threatened by PC control, the PLC supplier is upset about the PC application. In fact, they have joined the PC control wave.
The industrial PC has developed rapidly in China. Worldwide, there are two main types of industrial PCS: IPC, Compact PCI, and their deformators, such as AT96 bus, and so on. Because of basic automation and process automation of industrial PC running stability, hot plug and redundant configuration is very high, the existing IPC has not fully meet the requirements, will gradually withdraw from the field, will be replaced by CompactPCI - -based industrial PC, and IPC will occupy management automation level. Countries in 2001 set up a "based on industrial control computer of the industrialization of open control system" industrial automation major projects, the goal is to develop with independent intellectual property rights of a PC -based control system, in 3 ~ 5 years, occupy 30% ~ 50% of the domestic market, and to realize industrialization.
A few years ago, when "soft PLC" emerged, the industry thought that the industrial PC would replace PLC. However, there are two main reasons for today's industrial PC not to replace PLC: one is the system integration reason; Another is the software operating system Windows NT. A successful pc-based control system should have two points: one is that all work needs to be completed by software on one platform; The second is to provide customers with everything they need. It can be predicted that the competition between industrial PC and PLC will be mainly in high-end applications, with complex data and high equipment integration. Industrial PC is unlikely to compete with the low price of microplc, which is the fastest growing segment of the PLC market. From the development trend, the future of the control system is likely to exist between industrial PC and PLC, and these signs of integration have emerged.
Like PLC, the industrial PC market has remained flat for the past two years. Compared with PLC, industrial PC software is very cheap.
The PLC is developing in the direction of miniaturization, networking, PC and openness
There are about 200 PLC manufacturers worldwide, producing more than 300 kinds of products. Domestic PLC market is still dominated by foreign products such as Siemens, Modicon, a-b, OMRON, mitsubishi, GE products. After many years of development, there are about 30 PLC manufacturers in China, but none of them have formed a large-scale production capacity and famous brand products, so it is fair to say that the PLC has not yet formed manufacturing industrialization in China. In the application of PLC, China is very active and the application industry is very wide. Experts estimate that in 2000, the domestic market of PLC was 15 ~ 200,000 sets (about 90% imported), about 25 ~ 3.5 billion yuan, with annual growth rate of about 12%. The demand for PLC in China is expected to reach about 250,000 sets by 2005, about 35 ~ 4.5 billion yuan.
The PLC market also reflected the situation of manufacturing in the world, which fell sharply after 2000. But, according to the Automation Research Corp forecast, despite the global economic downturn, PLC market will recover, estimates that global PLC market in 2000 was $7.6 billion, will return to $7.6 billion by the end of 2005, and continued to increase slightly.
Microstructure, networking, PC and openness are the main direction of future development of PLC. In the early stage of PLC automation, PLC was large and expensive. But in recent years, microplcs (smaller than 32 I/O) have appeared, priced at just a few hundred euros. With the further improvement and development of Soft PLC control configuration software, the market share of Soft PLC configuration software and pc-based control will gradually increase.
Currently, one of the biggest trends in process control is the extension of Ethernet technology, and the PLC is no exception. Now more and more PLC suppliers are offering Ethernet interfaces. It can be believed that PLC will continue to transfer to the open control system, especially the control system based on industrial PC.
A DCS system for integrated design of measurement and control tube
The Distributed Control System of the Distributed Control System was introduced in 1975, and the manufacturers mainly concentrated in the United States, Japan, Germany and other countries. From the late 1970s, China first introduced DCS from large import equipment, and the first batch of imported projects, such as chemical fiber, ethylene and fertilizer, were introduced. At the time, the DCS of China's main industries, such as electricity, petrochemicals, building materials and metallurgy, were all imported. In the early 1980s, when introducing, digesting and absorbing, we began to develop the technology of localization DCS.
DCS market annual growth rate of about 20% in China, the forehead is about 30 years market (3.5 billion yuan. As a result of DCS in recent five years in large petrochemical industry automatic control device of no alternative products, so its market growth rate won't fall. According to statistics, by 2005, China's petrochemical industry has more than 1000 sets of equipment need to apply DCS control; power system, new clothes every year more than 1000 kw generators needs DCS for monitoring and many enterprises has used DCS nearly 15 ~ 20 years, needs to be updated and modification.
The control system is developing towards the field bus (FCS)
Due to the development of 3C (Computer, Control, Communication) technology, the process Control System will be developed by DCS to FCS (Fieldbus Control System). FCS can completely disperse PID control to Field Device. FCS based on fieldbus is distributed, full digital, full open and interoperable a new generation of the production process automation system, it will replace the one-to-one 4 ~ 20 ma analog signal lines, to the industrial automation control system of traditional architecture brings revolutionary change.
From the definition of the IEC61158 fieldbus is installed in a manufacturing or process area of the field device and control indoor between automatic control device of digital, bi-directional transmission and multi-branch communication network structure. The field bus has the ability of digital computation and digital communication to improve the measurement, transmission and control precision of the signal, and improve the function and performance of the system and equipment. IEC/TC65 SC65C/WG6 working group began in 1984 to launch the world's single fieldbus standards work, through the hardships of 16 years, in 1993 launched a IEC61158 2, after the standard was Mired in chaos.
In the development of the computer control system of the JiDeShi pneumatic instrument control system, electric unit modular analog instrument control system, centralized digital control system and distributed control system (DCS), will be in the direction of the field bus control system (FCS) development. Although FCS, based on the fieldbus, is developing rapidly, FCS development still has a lot of work to do, such as uniform standards and smart meters. In addition, the maintenance and transformation of traditional control system still require DCS, so it will take a long process for FCS to completely replace the traditional DCS, and the DCS itself is constantly evolving and improving. To be sure, FCS with new technologies such as DCS, industrial Ethernet and advanced control will have a strong vitality. Industrial Ethernet and fieldbus, as a kind of flexible, convenient and reliable way of data transmission, has been more and more used in industrial site, and will occupy more important position in the field of control.
The instrument technology of the instrument is developing in the direction of digitization, intelligentization, network and miniaturization
After 50 years of development, China has a basic instrument and meter industry, initially formed relatively complete categories of production, scientific research, marketing system, to become Asia excluding Japan's second largest producer of instruments and meters. With the international digital, intelligent, networked, miniaturized products gradually become mainstream, the gap will further increase. Most of China's high-end and large equipment relies on imports. Mid-range products and many key components, foreign products account for more than 60 percent of the Chinese market, while domestic analytical instruments account for less than two-thousandths of the global market.
In the future, the main development trend of instrument and instrument technology is to develop the instrument and instrument to the intelligent direction, and generate intelligent instruments. The PC of measurement and control equipment, virtual instrument technology will develop rapidly. The instrument and instrument network, generate network instrument and remote control system.
Several Suggestions: develop products with independent intellectual property rights and master core technologies; Strengthen the system integration capability of the instrument industry; Further expand the application field of instrumentation.
The technology of numerical control is developing to intellectualization, openness, network and informatization
From 1952, the United States at the Massachusetts institute of technology, developed the first experimental nc system with the rapid development of computer technology, a variety of different levels of open CNC system arises at the historic moment, developing very quickly. In terms of the structure, the numerical control system in the world can be divided into four types: 1. Traditional numerical control system; 2. Open CNC system of "PC embedded NC" structure; 3. Open CNC system of "NC embedded PC" structure; 4. SOFT type open CNC system.
China's development and production of CNC system, through the ">" introduction, digestion, absorption, "five-year" research and industrialization of the ninth five-year plan, and has made great progress, basically mastered the key technology, numerical control development, the production base, is established to cultivate a batch of numerical control talented person, initially formed their own numerical control industry, also led to the development of mechanical and electrical control and drive control technology. At the same time, the economic CNC system with Chinese characteristics has been developed over the years, and the performance and reliability of the products have been greatly improved and gradually recognized by users.
The general trend of the development of foreign numerical control system technology is that the new generation of numerical control system is developing towards PC and open architecture. Driving device to communicate and digitalization; Enhance communication function to network development; The numerical control system develops intelligently in the control performance.
Entering the 21st century, human society will gradually into the knowledge economy era, knowledge will become the capital and the dynamics of the development of the science and technology and production, and machine tool industry, as machine manufacturing, industrial equipment department and even the whole national economic development, there is no doubt that its important strategic position, degree of attention, also will be more highlighted.
Intelligent, open, networked, and informationalized as the main trend of the future development of numerical control system and numerical control machine tool: the development of high speed, high efficiency, high precision and high reliability; Development of modularization, intellectualization, flexibility, network and integration; Development of PC - based and open direction; The new generation of nc processing technology and equipment, mechanical processing to the virtual manufacturing direction; With the combination of information technology (IT) and machine tool, the advanced machine tools will be developed. Nanotechnology will form a new trend and will have new breakthroughs. Energy-saving and environmental protection machine tools will accelerate development and occupy the vast market.
The press industry control network will be integrated in the direction of cable and wireless
Wlan (Wireless LAN) technology can be wirelessly connected network equipment conveniently, people may at any time, anywhere, at random access to network resources, is the important direction of modern data communication system. Wireless LAN can provide Ethernet connectivity without using network cable. While promoting the development of network technology, wireless LAN is also changing the way people live. The wireless communication protocol usually USES IEEE802.3 for point-to-point mode, 802.11 for point-to-point mode. Wireless LAN can be based on the common local area network through wireless Hub, wireless access station (AP), wireless bridge, modems, and wireless network card and so on, to use the most common wireless network card. The future of wireless LAN is focused on security, mobile roaming, network management and relationships with other mobile communication systems such as 3G.
In the field of industrial automation, tens of thousands of sensors, detectors, computer, PLC, card reader equipment, need to connect with each other to form a control network, is usually the devices provide communication interface RS - 232 or RS - 485. Wireless LAN device isolation signal converter, the industrial equipment of RS - 232 serial signal and wireless local area network (LAN) and Ethernet signal transformation, conform to the IEEE 802.11 b wlan and IEEE 802.3 standard Ethernet networks, support the standard TCP/IP network communication protocol, the expansion of the effective industrial equipment networking communication ability.
The combination of computer network technology, wireless technology and smart sensor technology has created a new concept of "networked smart sensor based on wireless technology". This networked smart sensor based on wireless technology enables the data of industrial sites to be transmitted, distributed and Shared directly over the network via a wireless link. Wireless LAN technology to environment in the factory, for a variety of intelligent field devices, mobile robots and communication among the various kinds of automation equipment with high bandwidth wireless data link and flexible network topology, in some special environment effectively make up for the deficiency of the wired network, to further improve the communication performance of the industrial control network.
The software of industrial control is developing in the direction of advanced control
As an important part of industrial control software, the man-machine interface configuration software developed domestically made great progress in recent years, software and hardware, the combination of measurement, control, tube integration for the enterprise provides a more complete solution. On this basis, the industrial control software will develop from the human-computer interface and the basic strategy configuration to the advanced control.
Advanced Process Control has no strict and uniform definition. The control algorithm which is based on mathematical model and must be realized by computer is generally referred to as advanced process control strategy. For example, adaptive control; Predictive control; Robust control; Intelligent control (expert system, fuzzy control, neural network) etc.
Because of the huge economic benefits of advanced control and optimization software, these software are also worth more. There are already dozens of companies in the world, with hundreds of advanced control and optimization software products, and a powerful process industry application software industry in the world. Therefore, it is of great importance to develop the advanced control and optimization software of China's own intellectual property rights and to break the monopoly of foreign products and replace the import.
In the future, industrial control software will continue to develop towards standardization, networking, intelligence and openness.
Industrial informationization refers to the industrial production, management, business process, through the information infrastructure, the integration platform, realize the information collection, information transmission, information processing and comprehensive utilization of information, etc.
Due to vigorously develop industrial automation is to speed up the transform and upgrade traditional industry, improve the overall quality of enterprises, improve the overall national power, adjust the industrial structure, a fast enliven the large and medium-sized enterprises effective ways and means, the state will continue through the implementation of a series of industrial process automation special, high technology industrialization with informationization to drive industrialization, promote the further development of industrial automation technology, strengthen technology innovation, realize the industrialization, solving the deeper problems facing the development of national economy, further improve the whole quality of national economy and comprehensive national strength, to realize leap-forward development.
