摘要:

选用了源代码开放的实时嵌入式操作系统Windows CE 作为应用平台,设计了以32 位ARM 处理器为控制核心的制袋机走膜控制系统,控制系统采用“查询-工作”方式。开发了双伺服定长牵引系统,选用了能够安全带载运行的变频驱动器。运行结果表明,基于ARM 嵌入式的控制系统有效地提高了适时性和控制精度,实现了主电机转速、袋长、牵引速度之间的协调和多电机条件下定长牵引与恒张力走膜功能。

Abstract:

Feeding control system of bag-making machine was designed using 32 bit ARM CPU as control core and embedded operating system Windows-CE as application platform. The control system used "working-inquiring" mode. Dual-servo system was developed for the bag-making machine and frequency conversion driver capable of safe working with loading was selected. The operation result showed that the control system based on ARM Core CPU improves timeliness and control precision, and realizes constant tension feeding and the constant tension hauling and the coordinating among the rotational speed of the main motor, the length of bag, and the hauling speed.

Key words: ARM dual-servo fixed-length traction constant tension
