微型电脑应用

文章以PLC为主控制器设计纸机电气传动控制系统,并对纸机传动控制所涉及的速度链控制、张力控制、负荷分配控制以及系统通信等问题进行分析与研究,然后提出实现方法,利用PLC进行编程,随后针对控制系统的实现作好以下工作:(1)实现各PLC之间、PLC和上位监控计算机之间、PLC和操作面板之间的通信,并给出了程序框架:(2)分析研究速度链控制、张力控制、负荷分配控制的各类控制方法,并对其中控制效果较好的数字式速度链控制、直接张力控制、基于转矩控制的负荷分配控制等进行软件设计;(3)建立PLC和组态的通信方法,并对上位监控界面设计作好规划。

The design for regard PLC as principle controller design paper machine the electricity spread to move control system,and spread to move control the speed chain involve control to the paper machine,tension control,burden allotment control and system correspondence the etc.'s problem carry on analysis and research,then put forward realization method,then make use of the PLC carry on plait distance and aim at control system later on of realization make good the following work:(1)Of the PLC and operation front-panel of the,PLC and place of honor supervision calculator of each PLC of realization of correspondence,and give procedure frame;(2)Analysis research speed chain control,tension control,burden allotment control of every variety control method,and as to it's medium control the effect be better of numeral type speed chain control,direct tension control,according to turn Ju control of burden allotment control etc.carry on software design;(3) Establishment PLC and set Tai of correspondence method,and to place of honor supervision interface design make good programming.
