PROFIBUS in 300000 tons of coking engineering automation instrument engineering application

Abstract: the PROFIBUS in 300000 tons of coking engineering automation instrument engineering, the application of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. This plan is for a company's 300000 tons coking engineering automation instrumentation points in engineering design. With Germany's SIEMENS PROFIBUS fieldbus and industrial Ethernet technology, will this project including drum section, cold section of coke oven, the desulfurization section and heavy section. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the PROFIBUS in 300000 tons of coking engineering automation instrument engineering application of the article details. This plan is for a company's 300000 tons coking engineering automation instrumentation points in engineering design. With Germany's SIEMENS PROFIBUS fieldbus and industrial Ethernet technology, will this project including section, cold section, the desulfurization process of coke oven, heavy section and cooling section of advanced FCS control system. Implementation of blast section, the desulfurization section and heavy section control room centralized monitoring and switches control section used indoor on-site monitoring mode. The coke oven set 1, operation station 1 engineer station, drum, the desulfurization section, cold section in heavy section of an operating station, station 1 fellow engineers. The entire control by FCS system and human-machine interface of the industrial Ethernet system & ndash; — Operation station and its real-time monitoring software, complete the real-time monitoring and control of all functions, data processing, display, downtime interlock protection, manual operation, print, and connected to the Internet. PROFIBUS fieldbus system introduces generally the development of the control system of the early by zui adopts JiDeShi instrument control, centralized computer control system of the architecture of DCS and in recent years the development of fieldbus control system FCS three big stages of development. Fieldbus, it is the modern control technology, computer technology and network technology development, is the progress of the industrial automation business needs, and the necessity of developing technology. The fieldbus makes between field devices, field devices and equipment used in the control room network system. The fieldbus control system is the trend of the development of the control system. The three major characteristics of the fieldbus technology is digital signal transmission, control function diversified, open and interoperable. At present, the popular fieldbus are: FF - FoundationFieldBus ( The fieldbus foundation) Field bus, CAN ( Control of local area network) LONWORKS ( Local action network) 现场总线( Process field bus) And transitional HART ( Addressable remote sensor data path) Protocol such as five kinds of fieldbus. PROFIBUS field bus is mainly used in programmable controllers ( PLC） And the switch quantity detection system. That is to say, it is suitable for factory automation system. PROFIBUS is suitable for process control products, such as regulating valve, actuators, analog I/O module, digital I/O module, etc. Its open communication system can make the different vendor products work on the same bus system. Coking engineering system of the coking project is divided into two control center, a responsible for the monitoring and control of coke oven section, a cold is responsible for monitoring drum section, etc. This control system network is divided into upper management network and the lower control network, composed of S7 - in the middle 300 controller links constitute a complete control network. Upper management network by the fiber optic cable plus OLM ( Industrial Ethernet fiber link modules) Upward by the ITP (looping the frame, 9/15) Standard cable link operator station and engineer station, down by the ITP ( 9/15) S7 - standard cable link 300 on the Ethernet module, constitute a transfer rate of 10 m / 100 m redundant Ethernet, realization of operator station and engineer station and S7 - The data exchange between 300 controller. The lower control network composed of double Angle shielded wire PROFIBUS network. Control system adopts SIEMENSS7 - 300 PLC monitoring system USES SIEMENSWINCC, and configure the double hot standby server. The entire communication system includes real-time and high-speed industrial Ethernet control network DP network. Where each section adopts two sets of SIEMENS S7 - 315 programmable controller system, from the stand, plus digital quantity input, output, module and analog input and output module and network module industry to state an underlying as the PROFIBUS field bus, the upper layer of Ethernet control system, using two hot standby CPU module to realize the important parameters of the hardware, and use the monitoring software of SIEMENS WINCC monitor implementation of the system. Of coke drum section, cold section each with 1, operation station 1 engineer station, a printer. At the same time two sets of thermal monitoring system software, in order to improve the reliability of the system. Centralized monitoring system control chart.
