【摘要】 目前国内针对高档剑杆织机的控制系统尚无成功的商业应用实例,开发高档织机控制系统已是当前纺织机械行业的迫切需求。课题研发一个基于多处理器的剑杆织机控制系统,控制剑杆织机的各个机构协同动作,实现织造功能。控制系统采用一个上位机、五个下位机的系统结构,中间以现场总线RS-485连接。上位机运行织机操作软件,实现人机交互功能;五个下位分别控制织机各运动机构,实现织机动作的实时、协同控制。论文分别介绍了上位机及各个下位机的结构,实现的工艺功能以具体的电路设计方法;研究了织造过程中经纱张力的控制方法,提出了较为实用的基于模糊—PI并联控制的经纱张力控制算法,并成功应用;同时介绍了RS-485总线的应用细节和一些微机系统抗干扰的实用方法。本课题受浙江省重点自然科学基金(项目编号Z1090423)资助,研发的控制系统为高档剑杆织机的配套产品。课题的成功实施可填补国内技术空白,提高剑杆织机的自动化和智能化水平,促进我国纺织工业技术水平的提高与产业的转型升级。
【Abstract】 At present, there is no successful commercial application of a control system for high-grade rapier loom in China. And there is an urgent need of high-grade loom control system in textile machinery industry.The project focuses on research of a rapier loom control system based on multiprocessor, which controls various mechanism of loom to move conceitedly and achieve weaving function. The control system has six processors, one is host, and the other five are slavers. Field bus RS-485 is used to connect host and slavers. The host runs loom operating software, providing human-computer interaction interface. And the five slavers execute real-time and cooperative control for various mechanism of loom.The thesis introduced structure, process functions and specific circuit design of the host and slavers. Meanwhile, it studied warp tension control algorithm and presented a practical algorithm which consists of fuzzy control and PI control. Finally some application details of field bus RS-485 and some practical measures of microcomputer system anti-jamming are introduced in detail.The control system based on multiprocessor is an accessory product of high-grade rapier loom. It can improve automation level and intelligent level of loom. The project is supported by the Natural Science Foundation of Zhejiang Province and helps the transformation of textile industries and technological upgrading.
