Abstract


With the development of the textile industry to develop high-end loom control system is the important issue of textile machinery, loom warp tension control is the high-end loom control of the key technologies. With the development of Internet and the post-PC era, embedded systems become the focus of the IT industry, ARM-designed 32-bit RISC processor, with its many excellent performance, become embedded solution of choice. uClinux Linux not only has a highly modular, open source, etc., and all kinds of driver support with perfect and complete set of tools. Based on ARM and uClinux embedded warp tension control system is developed in this context. This paper analyzes the domestic and international tension control technology, leads to tension control in the loom control application. Analysis warp, winding its way to achieve technical features, introduced the concept of embedded systems and embedded system hardware and software components, the embedded operating system. Finally this design ideas and implementations. This body may be divided into the following four sections: System hardware architecture design and implementation, uClinux transplantation and analysis, design and implementation of driver, application design and implementation. In the hardware circuit design, made in the core of the main circuit S3C44B0X design and peripheral circuit design of two parts independent of the warp tension cooperative design system that integrates the whole loom control system. In the operating system migration and analysis, introduced uClinux transplant procedure, given the realization of the system boot process, and emphatically analyzed uClinux kernel structure for further application development for bedding. In the driver design and implementation aspects, introduced uClinux platform, the basic driver design process and gives the system used in the implementation of several major drivers. In the aspect of application design and implementation, through the multi-process and multi-threading features, analysis and comparison of the programming model is proposed using a single process, multi-threaded application design. Second, analysis of the characteristics and requirements of the fabric craft, given the system and PC communication protocol. Finally, the implementation of the various threads and thread synchronization and mutual exclusion between the discussion. This design of real-time control system, fast response, each weaving cycle of tension consistency, smooth control, to meet the requirements of high-end looms, with practical application value.
