提出多帧控制协议和节点互访协议,讨论了两种协议在CAN 协议上的实现及报文调度方法。采用多帧控制协议对多帧报文进行 传输控制。节点互访协议采用存储区映射的方法来建立节点之间的逻辑联系,借鉴了MODBUS 协议请求/应答形式的数据通信方法。实验 表明该设计应用于电梯控制系统,能充分满足性能指标要求。-Proposed multi-frame control protocol and node visits the agreement, the two discussed the agreement on the realization of CAN protocol and packet scheduling method. Control protocol used for multi-frame multi-frame message for transmission control. Visits node mapping protocol storage area using the method to create logical links between nodes, and draw on the MODBUS protocol request/response forms of data communication methods. Experiment results show that the design used in elevator control system, can fully meet the performance requirements.
