双捻机数字式控制系统

A digital control system designed for a double twisting strander

某型号双捻机由5台变频电机驱动,根据工艺要求,设备的运转速度需可调,且各电机之间要保持同步。基于变频调速技术和现场总线技术,研究开发了该双捻机数字式控制系统,文中介绍了系统的硬件构成和软件实现。经现场运用表明,系统运行情况良好,满足所要求的功能和精度要求。且使用维护方便。

A certain type of double twisting strander is driven by five frequency conversion motors. According to the characteristic of the production process, the velocity of equipment in use must be adjustable and the individual motors must keep synchronization. Based on the technique of speed governing through a converter and the field bus technology, a digital control system is developed for a double twisting strander. This paper presents the hardware structure and the software used in the system. The application shows that the system has good performance and can satisfy the functions and accuracy required. The system is also easy to maintain.
