Abstract
The traditional wiring connection of tractors faces difficulty in meeting the requirements of information sharing, high real-time performance, and high reliability among the electronic control units of electric tractors. This study takes a bifurcated power electric tractor as an example and designs the CAN communication network system of a bifurcated power electric tractor on the basis of ISO 11783 protocol. On the basis of the structural form and operation characteristics of the bifurcated power electric tractor, the CAN communication network nodes are divided, and the functions of each node are defined. This study aims at four common network topologies. A mathematical model is established on the basis of graph theory, the total information per second T and the node information per second Z of each structure are analyzed and compared, and the communication network of the electric tractor is designed by using high- and low-speed dual-bus structure. The communication protocol and system software design are developed on the basis of the ISO 11783 protocol. The hardware function and communication effect of the communication system are tested by dSPACE simulation platform and CANoe software. Test results show that the communication effect of the designed CAN bus network system is good, and the bus load rate is approximately 12%. This study provides a reference for the design of CAN communication network system for electric tractors.
