Configuration Of Industrial Real-Time Database And Development Of Data Exchanging Interface For Multi-source System

With the development of technology and the increasing complexity of production, it is required to monitor and control the very important process which is relevant to the stability of system and product quality for the safely and highly efficiently running of producing equipment, and Real-Time Database is the core of the whole system. Therefore, A general and efficient design approach using a Real-Time Database and interface technology to cope with a complex industrial producing process based on LLDPE (Linear Low Density Polyethylene) is presented in this paper.In order to realize the real time monitoring and control system of a industrial producing process, including the modeling of the industrial plant (LLDPE e.g.), the integrated monitoring and control of the producing process, the configuring of the computer hardware system, the interface and software of monitoring and control, the design of the real time database, and the design of the HMI, this paper represents a method combined with the design of Real-Time Database and the relative interface technology. Contents in this paper are as following:1. This paper introduces the characters of the Real-Time Database and analyzis application and development trend in process industry.2. Analyzing the characters and design requirements of the gas-fluidized polyethylene process, applying Aspen's Infoplus.21 as Database platform and introducing Infoplus.21 briefly.3. Based requirements of production process, this paper proposes the design of the application for Real-Time Database, mainly including the design of the database structure, the configuration and management for Real-Time Database, the security and backup mechanism.4. This paper realizes the interface's design and development for industrial linear low density polyethylene process. The development of the system applies the operating platform based on WEB. The monitoring and controlsystem for industrial linear low density polyethylene process comprises the software packet as the core and the real time database as the data exchange center. Compose the three components to the whole through the communication interfaces.5. With the long-time live operating of the monitoring and control system for industrial linear low density polyethylene process, a series of results and their analysis has been given out. Finally, the whole thesis is summarized, and some experiences of the Real-TimeDatabase application in the monitoring and control system for industrial linear lowdensity polyethylene process are given out.
