PLC冗余系统在冰蓄冷中央空调中的应用

摘要

In consideration of the control reliability, the backup redundant technology is introduced in the system design of ice thermal storage. It has achieved the monitoring of the large air conditioning system of ice thermal storage through advanced controller redundant technology,open computer networks and industrial Ethernet technology,remote IO cabinet on-site layout,reliable hardware systems and a good man-machine interface.%基于对控制可靠性的考虑,冰蓄冷的系统设计中引入了后备冗余技术,它通过先进的控制器冗余技术,开放的计算机网络及工业以太网技术、远程IO机柜现场布置方式,可靠的硬件系统和良好的人机界面,实现了大型冰蓄冷空调系统的监控.
