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.
