基于FlexRay总线的多节点通信设计

Design of Multi-node Communication Based on FlexRay Bus

针对FleaRay总线在分布式测控系统中多节点传输控制过程中功能单一的问题,将微控制器、通信控制器、总线收发器等组成电子控制单元,实现多节点网络间的静态段和动态段的数据收发通信等功能。实验表明:组成的通信网络的节点之间可进行数据收发,传输过程中无丢帧、错帧,满足分布式测控系统的可靠、精准要求。

In view of the single function of FleaRay bus in the multi-node transmission control process of distribu-ted measurement and control system,the electronic control unit is composed of microcontroller,communication con-troller and bus transceiver.And these electronic control units realize the functions of data transmission and commu-nication between static and dynamic segments of multi-node network.The experimental results show that the nodes of the communication network can send and receive data,and there is no frame loss or error in the transmission process,which meets the requirements of reliability and accuracy of the distributed measurement and control system.
