| Firstly, this article points out the reason of rapid development for industrial automation technology and influence for industrial production process caused by automation control technology, it also analyzes the leading technology development in this area. The industrial automation control technology solves the problem of production efficiency and conformity. The combination for new computer information science and automation technology bring huge technology innovation for industrial production process.Then, it detail analyzes and compares the industrial control system major including DCS,PLC,IPC and it form the industrial control technology. At the present, almost all the industrial control systems utilize these three control systems. Among them each system has its own performance advantage and also has own defectiveness. In the developing process every system complements and promotes each other for the structure and performance. All of them are developing in the direction of more reliability, opener and easier to maintenance. The limitation among all kinds of control systems is getting more and more faint. It is the general trends for amalgamation each other.Secondly, Control service for communication net of industrial automation system mainly uses to accomplish the data exchange among control system and I/O device and HMI, it also has strict real time requirement. Profile bus control system put the control function to the field, it is open and operation each other and complete separation distribution type control system, but the low speed of profile bus is not identical with the standard limits its development. The ethernet successfully solved the environmental adaptability and real time requirement. It takes the advantage of low cost and high communication speed and widely used standard in the world and substitute the various profile bus system for control system and utilize the Ethernet to realize the uniform communication from management level to industrial field level.Moreover, this article utilizes the above mentioned automation technology use to blast furnace coal injection automation control system for practice and analyzes the system concrete requirement. It also compares and selects and configures the industrial control computer and control net based on the actual production process. It is not only meet the maximum requirement of production process, but also consider the reliability and compatibility and easy to maintenance. It will finally composes high efficiency control system.Finally, this article present new system, which combine the management and control. Due to it successfully utilization in oil refining production, it is wildly used for many oil refining company in the world. Along with the rapidly development for the computer, control and communication technology it will be more and more utilization in all kinds of industrial areas. |
