【摘要】 剑杆织机是我国纺织机械行业中起步较晚，发展最快，目前应用最广的无梭织机。在剑杆织机的研制的过程中，其微处理器控制系统的设计对于织机系统有着非常重要的意义。采用高智能电子送经／电子卷取控制系统是近年来国际上先进织机的发展方向。 本文以剑杆织机控制系统为研究对象。根据纺织机械发展的方向，本织机控制系统采用了多处理器控制方案，该方案以两片8位和两片32位的嵌入式微处理器为控制核心，通过若干接口电路构成控制系统。该系统由四个微处理器协同工作实现其整个控制过程，其主要特点表现在速度快，控制精度高。 织机的运行过程中，故障监控系统对织机起着至关重要的作用，本文设计并实现了织机故障监控系统接口电路。本文提出了一种电子送经／电子卷取系统的控制方法，即采用无刷直流电机，在32位微处理器MC68331控制下，实现电子送经／电子卷取同步控制，能够有效的保证经纱的张力恒定，使织机具有精密的纬密。与传统的方法相比，该方法使织机机构大大简化，自动化程度高，织机同步性能好。本文对经纱张力控制系统和系统通信进行了深入研究、并设计了送经电机与卷取电机编码器接口电路和外围存储器扩展接口电路。另外，还详细介绍了设计中为解决该系统的干扰问题所采取得有效措施。更多还原

【Abstract】 In the field of textile machines in China, The rapier loom as a kind of later exploitation but fast development and presently widest application loom is a NEW LOOM. In the exploitation of the rapier loom, the design of its control system is very important. Using high intelligent control system of electronic let-off and electronic take-up is an international trend in several years.The control system of rapier loom is studied in this paper. According to the development of textile machines, a loom system controlled by several microprocessors is raised. Formed by several interfaces, this control system consists of two 8-bit microprocessors and two 32-bit microprocessors as hard core. It can control the operation of loom by four microprocessors working harmoniously. The main trait of this control system is high-speed and accurate-control.During the loom working, the supervisory system of loom is vital. The interfaces of this supervisory system have been not only designed but also completed in this paper. A method of the electronic let-off and electronic take-up system is brought forward. The new method utilizes brushless DC motors to complete electronic let-off and electronic take-up motion synchronously under 32-bit microprocessor MC68331. It can assure invariable warp tension and better synchronous loom. Compared with traditional method, this method can reduce loom mechanism and can make loom motion better synchronization and high autoimmunization. In this paper, the control system of warp tension and communication between systems are analyzed thoroughly. The interfaces of take-up motor and let-off motor coders and peripheral memory are designed. In addition, in this thesis we also resolve systematic anti-interference question successfully.更多还原
