摘要
针对国内棉袜机控制系统存在稳定性、实时性不高导致袜品有脱边、松散等现象,课题组设计了一种基于STM32F207主控芯片的控制系统。基于棉袜机结构和工艺的研究,通过对袜机关键工艺尤其是各步段走针轨迹的分析,提出了总体分层式控制结构;设计了基于STM32F207主控芯片的主控板硬件系统;设计了基于飞思卡尔KE06芯片的选针器、气阀和电机板控制系统;设计了基于CAN总线协议的主控与驱动板之间的数据传输形式;依据外接编码器脉冲计数获得当前针数和针位信号,设计了零位检测电路;结合RUMI WELLKNIT的AOTU RSD机型的棉袜机,进行了功能测试。研究结果表明:设计出的控制系统可精准控制执行器,各执行器配合良好,针位位置捕获准确,实时性高;编织的袜品花型图案连接完好,袜品没有脱边和松散等现象。
In order to solve the problem of loose hosiery products that caused by the poor stability and low real-time performance of the domestic cotton socks machine control system,a control system based on STM32 F207 main control chip was proposed.Based on the research of the structure and technology of the cotton socks machine,through the analysis of the key process of the socks machine,especially the trajectory of each step,the overall hierarchical control structure was proposed,and the hardware system of main control chip based on STM32 F207 was designed.The control system of the needle selector,air valve and motor board based on Freescale KE06 chip was designed.The data transmission form between the main control and the drive board was designed based on CAN bus protocol.According to the external encoder pulse count,the current needle number and needle position signal were obtained and the zerodetection circuit was designed.The function test was carried out in combination with RUMI WELLKNIT’s AOTU RSD model cotton socks machine.The research results show that the designed control system can precisely control the actuator with good coordination,and the accurate needle position capture and the high real-time performance is achieved.The pattern of woven socks is well connected and socks has no detachment or loose.
