order
At present, China's industry is developing very fast, and more and more advanced technologies are applied in the process of industrial development, which also makes the industry gradually realize automation in the process of development, and the development speed of electrical automation is very fast. Automation has achieved good results in the development process. At the same time, the operation of automatic mechanical equipment is very simple, and it can be operated and performed by itself without anyone, and the operation is also very accurate. The application of automation technology in the industrial field can better reduce people's labor intensity, and at the same time, it can also liberate people from the harsh working environment.
I. Important features
Usually in practical application, the electrical equipment of industrial electrification system will be installed in the distribution room and control center according to different requirements. If there are many information tasks to be processed and there are naturally many system accessories of industrial electrification system, then the related maintenance work is relatively complicated. Compared with the thermal system, the operating frequency of electrical equipment is lower. When some electrical equipment works normally, it takes a long time to run, sometimes once every few months or longer. As far as the safety of electrical equipment is concerned, it requires high protection and placement, and high speed. It is generally required to complete the protection action within 40 ms ... Electrical equipment has the structural characteristics of simple interlocking logic and complex operating mechanism. Its control mode is electric power system, and the main equipment monitoring is connected to DCS system, which mainly needs two units to facilitate the maintenance of one system and the normal interference of the other system, and mainly ensure the stable operation of electric control mode. Therefore, when building DCS, the key to ensure the high reliability of the system lies in the networking mode of the system architecture.
Second, the application of industrial electrical automation
Computer technology has been widely used in enterprise management and has become a standard platform for industrial control. The control system based on PC has been well received by many industries. It is not only flexible, but also easy to integrate and maintain. Since the international standard IEC6 1 13 1 was formulated, the programming interface has become more standardized, and all major PLC manufacturers have followed this specification. Many products launched can meet the requirements of this standard. Among them, many PC control software are also developed according to this standard. In the industrial field, electrical automation has always been highly valued. Fieldbus refers to the communication system connecting intelligent field devices and automation systems, which mainly solves the related problems of information transmission between systems. Its appearance has added new vitality to the industrial field and is of great significance to industrial production. It has been widely used in various fields. Compared with other control systems, fieldbus control system has the characteristics of full digitalization, openness, interoperability and intelligence, and has become the development direction of industrial production automation. Fieldbus control system can effectively save enterprise costs. The setting of field bus is relatively simple, and less equipment is used, which saves the investment cost of equipment. In addition, it can reduce the use of cables in the later period and save related construction costs, which is of great significance for enterprises to achieve economic benefits. At present, the development of fieldbus control system is still immature, and it exists in industrial production together with distributed control system. Advanced control has good control effect. In the process of industrial production, it is not easy to establish a mathematical model. After adopting predictive control technology, the requirements for mathematical models will be reduced. Advanced control technology can not only predict the model, but also carry out inferential control. In addition, advanced control can also deal with complex multivariable. Advanced control is realized by computer technology, data processing, data transmission, model identification and other functions are realized by computer, which is the development platform of advanced control. Intelligence is the development trend of advanced control, and the production process needs intelligent system, which can be used for fault diagnosis and monitoring.
Third, the development strategy of industrial electrical automation
1, the program interface should be standardized and unified.
The symbol of modern industrial electrical automation is a unified interface with standardization. A standardized program interface can solve many practical problems, such as data and information exchange, system compatibility and so on. Modern computer application technology and network development technology should be combined to unify the program interface standards of all links as much as possible, so as to effectively improve work efficiency. When connected with MES system and ERP system of enterprises, platform automation of computer technology can help solve this problem. Using WindowsNT/2000 as the operating system can also standardize the office environment, and the computer can establish the interface between the electrification management and the system platform. Standardized program interface also ensures the communication between different programs, which is the main structure for the future development of electrical automation.
2. General network structure
In the process of enterprise development, it is necessary to ensure that the network structure of the enterprise can ensure the unimpeded data transmission of each system during operation. In the process of enterprise operation, it is necessary to control the field equipment, and the management system of the enterprise also needs to transmit data. Therefore, the management of the enterprise can use the usual network technology to monitor the operation of field equipment in real time. When planning the enterprise network, when communicating with field devices and office systems, Ethernet should be selected, which can better ensure the office automation environment to be better controlled and improve the control range of the system to a certain extent. The network should be able to better manage the network configuration and programming data during operation, and at the same time realize the integrated function of communication.
3. Develop a unified application system platform.
In order to make electrical automation control system play a better role and promote effective industrial production, it is necessary to establish a unified, standardized, open and healthy application platform. Excellent application system platform can support various operations of industrial electrical automation control and provide auxiliary functions for the actual functions of the system. It can reduce the use cost of the system, improve the comprehensive utilization efficiency of electrical equipment and improve the use efficiency of the whole system. At the same time, the establishment of the platform can also meet the individual needs of users, which is conducive to the realization of independent system goals. In practical application, we can run the code according to the actual needs of industrial production and customer goals, and download the corresponding code to the hardware programmable logic controller.
Fourth, the development trend of industrial automation
The development of electrical automation has brought great changes to industrial development, which has realized energy saving in industrial production process and reduced production cost, which can better ensure more economic and social benefits in industrial production. The development of electrical automation can better develop China's industrial development and narrow the gap between China and developed countries in the process of industrial development. In the process of development, industrial automation has gradually appeared different development trends, which are mainly divided into distribution, openness and informationization. The distributed structure can better realize the independent working environment of each functional module under the network environment, and at the same time, it can better disperse the existing system risks. The openness of the system structure can realize the connection between the system and the external network, and informatization can make the system do better in information processing, and realize the integration of network automation and management and control. The improvement of industrial electrical automation level can better promote China's industry to obtain better development prospects.
The penetration of information technology into the industrial world comes from two independent directions, on the one hand, from the vertical penetration of management, on the other hand, from the horizontal expansion of information technology to automation equipment, machines and systems. Information technology has penetrated into all levels of products, including not only controllers and instruments, but also sensors and actuators. The standard browser can access the financial and personnel management data of the enterprise for the use of the enterprise management, and can also monitor the dynamic picture of the current production process to obtain the most comprehensive and accurate production information at the first time. The development of microelectronics and microprocessors is the driving force of information technology revolution. With the wide application of microelectronics and microprocessor technology, the original clearly defined equipment boundary, corresponding software structure, communication ability and easy-to-use unified configuration environment have become important.
Concluding remarks
The development of electrical automation has gone through a long process. From the initial conception to the present gradual maturity, its development is closely related to information technology and physical science. There are many problems to be solved in the development of electrical automation technology. In order to better develop electrical automation technology, we must constantly apply high and new technology, so as to better ensure the better application of electrical automation technology in industrial production and bring greater convenience to industrial production.
