摘要
讨论了电脑提花大圆机电子选针器的下位机控制系统与上位机的通讯、程序的实现及构成电子选针器控制系统的程序管理。文中以PC104为上位机,AT89C51单片机为下位机,介绍了其主从两级控制系统的电子选针硬、软件设计,并阐述了Flash存储管理程序、选针数据的读取处理程序、上位机与下位机通讯命令等的下位机程序的具体实现。
This paper discusses the communications and programming between the lower position control system and the upper one of the electronic needle selector on computer-based large diameter circular knitting machine, and the program management of the electronic needle selector control system. PC104 is used as the upper position control system and AT89C51 as the lower one. It introduces that the hardware and software design of the main and secondary electronic needle selector control system, and analyzes the management program of FLASH memory, data reading of needle selector and the lower system-based actual realization of the communicating commands between the upper position control system and the upper one.
