摘要
通过对混凝土搅拌楼电子叠加器的设计,讨论搅拌楼各料叠加的控制方式,阐述利用PLC(Programmable Logic Controler)可编程序控制器设计一个工程项目的全过程,对现有电气设备的自动化改造提供了方法,实现了混凝土搅拌楼的三料自动叠加.
Through the design of the electric mixing device for cement blender, the control patterns of the blender are discussed. This paper introduces the whole process of designing a project using PLC. This approach gives a model for the automation renovation of the old instruments, realizing the three-material mixing in the cement blender. And the result can be used in engineering.
