摘要：为提高织物质量和满足喷气织机高速工况的要求，在ARM微控制器LPC2294的丰富硬件资源的基础上，研制了具有高速、高实时性的电子送经卷取控制系统。采用模块化方式设计硬件电路，在软件控制上采用具有高实时性的μC/OSII实时操作系统。该架构不但便于系统升级和维护，而且经过对张力采样时间的分析和计算，证实其满足系统的高实时性要求。另外，系统采用多主CANbus通讯技术与主控制器进行信息通讯，提高了织机的工作效率。

Abstract: To improve the quality of textile and satisfy the requirement of high speed about airjet loom, an electronic takeup and letoff control system was designed, with high speed and excellent real time performance by employing LPC2294 for its abundant hardware resources. The μC/OSII was used as realtime operation system(RTOS) to implement letoff and takeup function, and hardware circuit was designed in the way of modularization. The μC/OSII enabled the system to be convenient for upgrade and maintenance, and satisfied the high realtime requirements by analyzing and calculating the sampling time of tension. By employing the CANbus technique, the system can communicate with other controller of loom directly, thus the loom efficiency is enhanced.
Key words: LPC2294; CANbus; μC/OSII; airjet loom; takeup and letoff
