采用微机实现气动系统的控制,是目前国内外气动技术发展的重要方向之一。本文作者正是根据这一发展趋势研制成功了一种可编程控制器,它具有成本低、功能全、输出输入容量大,可编程等优点,特别适合气动系统。可以预见,随着这一新技术的推广普及,必然会带来可喜的经济效益。现在简要介绍本控制器的原理和功能。一、可编程控制器的硬件系统本控制器主要分两部分:微机控制器主机和I/O 接口板。微机控制器主机(如图1所示)是以Z80CPU 为核心的。在其只读存贮器中,存有监控程序、气动语言支持软
It is one of the important directions for the development of pneumatic technology at home and abroad to adopt computer to realize the control of pneumatic system. The author of this paper has successfully developed a programmable controller based on this trend. It has the advantages of low cost, full function, large input and output capacity, and programmable, especially suitable for pneumatic system. It is foreseeable that with the popularization of this new technology, it is bound to bring encouraging economic benefits. Now briefly introduce the principle and function of this controller. First, the programmable controller hardware system The controller is divided into two parts: the mainframe computer controller and I / O interface board. Microcomputer controller host (shown in Figure 1) is based on the Z80CPU. In its read-only memory, there is a monitoring program, pneumatic language support soft
