| Abstract: | A reliable distributed measurement and control system that adopted FlexRay Bus as field measurement and control net is proposed in this paper.FlexRay communication protocol is a time-triggered protocol,which is more real-time,dependable and has high data transfer rate.It makes it possible for the original communication in the industrial field control system bus （like RS485 and CAN） to renew.This paper discusses the FlexRay bus technology of hardware structure and communication protocols,using MC9S12XF512 Freescale MCU as the main chip,manages to achieve the communication between multi-nodes.It has laid foundation for FlexRay bus technology in the of the distributed measurement and control system application |
