喷气织机原理及PLC控制系统的研究

可编程控制器(简称PLC)以微处理器为基础，结合计算机技术、自动控制技术以及它
面向控制过程，面向用户等特点。近年来，国内许多纺织厂都把PLC 应用于无梭织机的电气控制，将人机界面、编码器、断纱检测装置、多臂机、电磁离合器以及PLC 等装置合理组合配置，构建PLC 控制系统控制织机的动作。PLC 技术的应用在提高织机布面质量、扩大织物品种、提高织机的效率、简化操作、减轻劳动强度等方面起到了至关重要的作用。

Abstract: The programmable controller (i.e. PLC) take the microprocessor as a foundation, comprehensive computer technology, automatic control technology as well as it face controlled process, face characteristics and so on user. In recent years, the domestic many textile mills all applied PLC in the shuttleless loom electrical control, the man-machine contact surface, the encoder, breaks gauze equipment reasonable combination dispositions and so
on detector set, dobby, magnetic clutch as well as PLC, constructed the PLC control system to control the loom the movement. The PLC technology application was improving the loom cloth cover quality, the expanded fabric variety, enhances the loom the efficiency, the simplification operation, reduces aspects and so on labor intensity to play the very important role.
