【摘要】 剑杆织机是应用最广泛的无梭织机之一。剑杆织机自动化和网络化的研制具有很高的经济价值。本文论述一种新型剑杆织机控制系统的研究与开发，主要工作如下： 1．分析了国内外纺织机械，特别是剑杆织机的历史及研究现状。详细研究了剑杆织机的工作机理、系统构成和控制方式，并提出了自己的控制方案。 2．以TMS320LF2407 DSP微处理器为核心，设计了输入输出主控模块，该模块包括各种机上传感器及操作按键信号的采集、处理和输出控制。 3．设计了DSP和单片机间的数据传输软件及硬件电路。利用单片机驱动SED1335液晶显示控制器，实现了织机控制系统的人机交互功能。 4．分析比较了两种工业控制网络系统。根据纺织厂的具体情况，结合DSP的特点，设计了基于CAN现场总线的织机通信网络接口模块。 5．对输入输出主控模块、串行通信显示模块和CAN通信模块进行了分析测试。为提高系统的抗干扰性，在硬件和软件设计方面都采取了对应措施。 最后对该控制系统的改进做了展望。该系统实时性好，性价比高，应用前景广阔。更多还原

【Abstract】 The rapier loom is one of the most widespread no-shuttle weaving machines. The automatization and network of the rapier loom become a commercial allure. This paper is about the research and design of a novel rapier loom control system, which is consisted of the following parts:1. Analyzed the current condition and the history of the textile machine both in China and abroad. Studied on the theory, the component and the control of the rapier loom, then brought up the more advanced project.2. Based on the DSP MPU, TMS320LF2407, an in-out control module was designed, including the collection, the management and the output of signals, which come from the rapier loom and buttons.3. The software and hardware were designed, which be used to transferred the system’s data between the DSP and the MCU. In virtue of the MCU, the LCD control device, SED1335, was driven, and the alternation interface function of the system was realized.4. Through comparing between the two control networks, considering the characteristics of the textile factory and the DSP, a network module was designed, which is based on CAN bus.5. Every module and whole system were tested several times, and the relevantimprovements were provided. For the better anti-jamming of the system, many measures were considered while the hardware and the software were being designed. At last, the future of the system was proposed.The performance of the control system is predominant and inexpensive, which would be used widely.更多还原
