The DSP-based Field-Bus Control System And In The TiCL4 Production Application

The occurrence and development of the field-bus lead to a revolution in the area of industrial control. Featured by full-digitalization,full-dispersal and full-openness,field-bus is now a"hot spot"because it adapts to the development trend for industrial control area of dispersal,network and intelligence.Field-bus control system as a new generation of Control System, on the one hand, it breaks the DCS system what uses a dedicated communications network limitations and uses the open standardized solutions to overcome the closed system caused defects.On the other hand, the DCS of combining centralization and decentralization of the distribution system, has become a new type of full-distributed architecture, and under the complete control on the scene, it represents full-openness, full-dispersion and Digital communications of features.In this paper, MMB2005 fieldbus control system is SHCAN2000system upgrade. It uses TI's TMS320F2812 DSP chip replace to the original 8-bit single-chip, and uses the OPC standard interface replace to I/O drive, and can communicate any of the industry control configuration software. Micro-Message Bus Integrated Development Environment (MMBIDE) to adopt international standards programming language structured text language configuration, the configuration has greatly enhanced the readability of the language. System uses concentrated a number of advanced technology, has greatly enhanced stability and reliability of operation, so that the number of smart meters in harsh environment applications of electromagnetic interference can be widely used in electric power, petrochemical, metallurgy, paper making, printing and dyeing, brewing and other industries.Titanium tetrachloride is titanium and titanium compounds important product in the middle of the production process. In the titanium industry, has extremely important position and wide range of functions. During the design, MMB2005 Field-bus Control System design on the production of titanium tetrachloride in the process of powder delivery unit, chlorination units and liquid chlorine units monitoring system for production control to provide on-site equipment, real-time data, according to the process Parameter auto-complete the production of titanium tetrachloride in the temperature, pressure, flow control signals. In the PC monitor screen can be intuitive to the scene to monitor all equipment production technology, equipment operation, and other data to improve product quality, reduce on-site operations, increased productivity and automation achieved.MMB2005-Fieldbus Control System is powerful and effective control system, with a high degree of intelligence, industrial control in the field of application with good value.
