基于Omron小型PLC的制冷机组控制系统设计

摘要

This article takes the design of the controller system of the screw refrigeration compressor as the framework,introduces the application of small Omron PLC to the parallel control of more than one refrigeration compressor and presents a design of hard-ware system integration and software module,which makes it meet the users'requirements.%以螺杆式制冷压缩机组的控制设计为背景,介绍了如何采用Omron小型PLC实现对多台压缩机制冷机组进行并联控制,给出系统硬件组成及软件模块的设计方案.该方案经过多年的使用验证,能够很好地满足用户的使用要求.
