摘　　要：自动焊接的应用越来越广泛,焊丝需求量也越来越大,同时要求层绕设备应适应各种规格的焊丝,且运动精准可靠,自动化程度高。测控网络技术的应用为实现生产过程的自动化,提高产品质量和安全生产提供了保障。基于Modbus协议的层绕机测控系统采用总线结构,RS-485串行总线通信,通过网络实时精确控制,提高了缠绕精度和自动化程度。焊丝主动导开技术的实现弥补了国内同类产品的不足。设备经现场使用,性能稳定,工作可靠。The application of automatic welding is more and more extensive, and the demand of solder wire is also much bigger. So the tiered twister machine should adapt various specification solder wire, and move precisely and reliability, automation degree and quality highly, output big. The application of network measurement and control technology provides guarantee for carrying out automatic producing process, exalting product quality and the safety production. The measurement and control system of the tiered twister based on Modbus protocol adopts mainline structure, serial parallel communicating by RS- 485. The intertwist precision of the solder wire and the automation degree are improved by network real time precision control. The technology realization of the solder wire unwinding actively makes up the shortage of the congener domestic production. Applying the machine at the field, it performance stability and work reliability.
