摘要
在中小型跑泉控制系统中,采用PLC控制或是网口控制方式相对来说成本高,系统较复杂.针对此情况,采用"串转并"思想,即单片机通过串行总线(串行时钟,使能信号和数据信号)连接各电磁阀驱动模块,电磁阀驱动模块中的"串转并"芯片,将串行数据转换为并行输出,从而控制电磁阀的通断.基于"串转并"方式的单片机跑泉控制系统,已经在多个喷泉中应用,控制效果好,接口简单,成本低,易扩展.
Abstract
In the small and medium-sized spring running control system,the PLC control system or network control system are relatively expensive and complex.In order to solve this problem,this paper presents a single chip microcomputer running spring control system based on"series to parallel",which follows the working principle of running spring,the hardware composition and software program of running spring control system.At present,this control system has been applied in many fountains with good control effect due to its advantages of simple interface,low cost and easy expansion.
