In this paper, a electronic jacquard control system based on CAN field bus is brought forward,using CAN bus as the main communication equipment, single-chip as the processor, IPC as the system support, piezo jacquard as the implementation of state institutions, making the communications of the system flexible and reliable, fatigue resistance and stability good, transmission of the pattern correctly, and so on. Hope to provide a theoretical support for China´s development of China-made electronic jacquard control system.
