HR-I电子提花机控制器的设计

Design of HR-I electronic jacquard machine controller

针对如何快速地改变花形,废除纹板,减少资金和材料浪费等问题,在研究和分析国内外电子提花技术的基础上,提出一种低成本的电子提花控制技术方案,以代替机械提花机。以单片机ATmega128为核心,利用CAN总线传输提花数据,实现数据远距离的传输,利用ATmega16接收CAN总线上的数据,在中断信号作用下通过同步串行口把数据分发到各个组件上,信号经过功率放大,驱动电磁阀,用提针控制经纱沉浮。该系统经现场测试,可实现无差错数据传输,可靠性好,抗干扰性强,能方便地改变花形,满足织造要求,从而提高生产效率。

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 in weaving requirement,and raising the productivity.
