Abstract:

For rapid change of pattern and abandon of jacquard card, reduction of the waste of funds and materials，this paper proposed a low cost electronic jacquard control technology aiming to in replace of the mechanical jacquard based on analysis of domestic and foreign electronic jacquard technology, The MCU ATmega128 is used as the core, jacquard data transmission is affected by CAN-bus, thus realizing long-distance transmission of the data. The MCU ATmega16 receives the data from CAN-bus, and distributes data to the jacquard Modules through synchronous serial interfaces under external interrupted signal. The amplified signal drives the electromagnetic valve and the jacquard loom controls the motion of individual warp yarn. The on-site experiments show that the system is characterized by non-error data transmission, good reliability and anti-interference, rapid and convenient change of pattern, satisfaction of weaving requirement, and raising the productivity.
