浆纱机的PC控制系统

PC Control System of Sizing Machine

本文探讨浆纱机原电气控制系统采用PC组成新的控制系统的设计.给出了控制系统梯形图并对主电动机进行过载及短路保护设计.阐明了系统工作原理,同时简介了接口电路及模拟实验的概况.该系统可实现自动化的集中控制与灵活的分散控制.

This paper discusses a modified design of the sizing machine ele.ctronical control system with PC. It gives a ladder diagram of control system and a design of overload and shortcut protection for major motor. It also introduces the principle of the system, interface circuit,and anological experiment. This system can realize the auto-concentrating control and flexible multiple control.
