Research And Implementation Of Ethernet Foundation Field-bus Communication System

The field-bus is connects the intelligent scene equipment and the automated system digital,the two-way transmission, the multi-branched structures correspondence network. The field-buscontrol system not only is one opening correspondence network, also is one kind of entiredistribution control system. It takes the intelligent equipment the relation link, hangs meets onthe main line, takes the network point the intelligent equipment connection is the network system,and further constitutes the automated system, the realization basic control, compensates thecomputation, the parameter revises, reports to the police, the demonstration, the monitoring,the optimization and controls the tube integration the synthesis automation function. This article first to foundation field-bus high speed Ethernet (FF-HSE) the correspondencemodel, the system structure and so on carried on the introduction. FF-HSE is similar withFF-H1, used the Ethernet +TCP/IP agreement in the first floor. FF-HSE is divided for theCommunication Entity (CE), the System Management Kernel(SMK) and the Field-busApplication Process (AP), conducted the thorough research to its correspondence main part——Communication Entity. Completed in FF-HSE the SNTP agreement research and therealization, based on TCP (UDP) the /IP agreement data transmission, improved the CRCerror-detecting code production. The paper another part is to the Intelligent Temperature Instrument preliminary research.Introduced the Intelligent Temperature Instrument function, the field-bus measuring appliancecharacteristic, in the intelligent measuring appliance composition, intelligent measuringappliance data processing as well as the technology and so on. While conducts the research to theabove question, realized in the intelligent measuring appliance partial function: Realizes in themeasuring appliance double monolithic integrated circuit correspondence, the intelligentmeasuring appliance same the position machine correspondence. This topic is tries hard to realize the FF agreement correspondence function, as well as tothe intelligent measuring appliance preliminary research and the realization, promotes the fieldbus technology development and the application.
