Research Of The Polishing Treatment Control System On FCS

Fieldbus technology is the computer digital ommunications technology to the development of industrial automation products.It is a kind of open digitized and the multi-spot communication scene of FCS net technology.And it makes control systems and equipment at the scene with communications each other when Production at the scene strengthen the ability to control the process with the system's operation stability Improvement.When Fieldbus technology are successful to applicate in the production plant,the production of the plant automation level and management of the modem level of automation and control capacity at the scene were improved.This paper research FCS applied on the spot fine handling control systems by plant operation and the actual operational requirements.Through research fieldbus networks for industrial production at the scene of some problems.propose solutions According to the production process and design Fieldbus fine handling control systems.First,This paper used in the production site to be solved several key issues proceed from the fieldbus control network technology.Analysis the fieldbus signal interference problems.Give the hardware and software solutions.Fieldbus communication from the real-time information and the uncertainty of starting.In the fine treatment in the control system of token ring communications network access method to solve the problem of information transmission.Second,ControlNet the scene of the bus protocol,the bus mode of communication and information frame structure.Finally,Through research fieldbus technology features principles and application of the current power plant technology.Fine treatment from the fieldbus control system requirements,With polishing process,Sheets of high-speed mixed yuan and regeneration unit on a logic of the design process.Choose the right field bus processors and control module,and so on to build the scene of the bus polishing control system,finish Fieldbus fine treatment under the control system by ControlNet FCS,iFIX and Rslinx software.From the power plant of the practical operation.Stability of the whole system running,there are still some problems.This requires the practical operation in light of the new situation to adjust.
