Fieldbus is connected intelligent field devices and automation systems digital, two-way transmission , multi-branch structure of the communication network . Fieldbus control system is both an open communication network , is a fully distributed control system . As the link of smart devices on the bus , as a network node smart devices connected to the network system , and further major automation systems , basic control , compensation , parameter modification , alarm , display, monitor , optimize integrated and comprehensive automation and control functions . Firstly, FOUNDATION fieldbus High Speed ??Ethernet ( FF - HSE ) communication model , architecture , etc. were introduced. FF - HSE and FF - H1 is similar to the underlying Ethernet TCP / IP protocol . FF - HSE is divided into communication entity ( CE ) , System Management Kernel ( SMK ) and the the fieldbus application process ( AP ) , the main part of their communication - communication entities conducted in-depth research . Research and Implementation of FF - HSE in the SNTP protocol , TCP ( UDP ) / IP protocol - based data transfer , improved CRC error detection code generation . Another part of the preliminary study of intelligent temperature instrument . Describes the function of intelligent temperature instrument , the characteristics of the fieldbus instruments , the composition of the smart meter , smart meter data processing , as well as anti-jamming technology . Study the above issues at the same time , the smart meter Some features : instruments in the single-chip communication , intelligent instruments , ibid bit machine communication . This project is trying to achieve the FF protocol communication functions , and the smart meter preliminary research and to promote the development and application of fieldbus technology .
