基于嵌入式的现场总线和TCP/IP协议转换的技术研究
Research on embedded system based conversion technology between fieldbus and TCP/IP protocol
摘要
Abstract
The interconnection of enterprise control network and information network is researched to transmit the data be-tween control network and information network. The fieldbus protocol is adopted by enterprise control network which is based on fieldbus,and the TCP/IP protocol is adopted by information network which is based on industrial Ethernet,so the integration of the two networks is turned to the conversion between fieldbus protocol and TCP/IP protocol. Considering the diversity of the field-bus,the RS 232,RS 485 and CAN bus protocols widely used in fieldbus are studied emphatically. The embedded system with a 32-bit microprocessor AT91RM9200 has the characteristics of high speed processing,small size and steady performance,and is the preferred selection to the hardware platform of the embedded gateway. The network layer model of protocol conversion was established,the hardware and the software platforms were designed to realize the conversion between fieldbus protocol and TCP/IP protocol. The running condition of the protocol conversion was tested to implement the two-way data transmission between fieldbus(RS 232,RS 485,CAN bus)protocol and TCP/IP protocol. The system can be applied in the fields of industrial pro-duction,home gateway and remote control.关键词
