| 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 STM32F207 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 STM32F207 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 zero detection 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. |
