Abstract

CAN is a kind of real time field bus and has been widely used in the automatic control and testing field. Compared to traditional communication methods such as RS-485, it has great advantages in the data translating speed and reliability. Data communication in ECU testing system has strict time requirement which is difficult for traditional communication system to achieve. According to the communication characteristics of ECU testing system, a multi-CAN communication network based on the CAN-bus is designed in this paper. It introduces the basic structure, sub-nodes hardware interface and software design of the communication network in detail, and provided a real time, reliable and flexible communication system based on CAN bus.
