title: Protocol description and optimization scheduling for multi-fieldbus integration system.
abstract: Device integration technique is applied to integrate different fieldbus devices into one control system. At present mature integration techniques use appropriative software to support corresponding protocols. New software must be developed when a new fieldbus is integrated. In this research, a universal protocol description method is proposed. It focuses on the packets encapsulation description, and different protocol messages can be encapsulated and parsed by the interpreter in a unified way. Moreover, in order to ensure the communication efficiency and QoS of different kinds of messages, packets encapsulated via protocol description are optimized and scheduled before transmission inside the interpreter. The approaches have been applied in the prototype of a software product and verified in a power monitoring project.
