摘　　要：针对机械排线式绞线机排线机构复杂、生产成本高、安装调试繁琐、需要根据工艺要求频繁更换机械部件等缺点,设计了绞线机的电气排线系统,系统采用步进电机自动排线。绞线本身工作过程的特殊性决定了主控PLC设置的参数不能通过有线方式传给排线控制器,所以设计了基于NRF24L01的无线通信系统,包括无线发送和无线接收两部分。同时,因为排线过程需要频繁往复运动,所以引入了S加减速曲线来控制排线步进的起动、停止、反向及变速过程,保证了排线的均匀性和收线张力的恒定性。排线系统总体结构由主控1200 PLC、NRF24L01的无线发射端、NRF24L01的无线接收端、STM32排线控制器、步进电机系统等组成。实际测验证实,该系统设计合理、稳定可靠,简化了绞线机的机械结构,满足实际生产工艺要求。Aiming at the shortcomings of the mechanical arranging wire twisting machine′s complicated wiring mechanism, high production cost, cumbersome installation and debugging, and frequent replacement of mechanical parts according to process requirements, the electrical wiring system of the stranding machine was designed, which used a stepper motor automatic cable. The particularity of the working process of the stranded wire determined that the parameters set by the main control PLC cannot be transmitted to the cable controller by wire, so a wireless communication system based on NRF24L01 was designed, including two parts: wireless transmission and wireless reception. At the same time, because the winding process requires frequent reciprocating motion, the S acceleration and deceleration curve was introduced to control the start, stop, reverse and speed change process of the winding step to ensure the uniformity of the winding and the constancy of the winding tension. The overall structure of the cable system consisted of the main control 1200 PLC, the wireless transmitter of NRF24L01, the wireless receiver of NRF24L01, the STM32 cable controller, and the stepper motor system. The actual test verifies that the system is designed to be reasonable, stable and reliable, which simplified the mechanical structure of the stranding machine and met the actual production process requirements.
