Ethernet-based remote distributed control system for central air conditioner

This paper develops a remote distributed control system (DCS) for central air conditioner based on the Ethernet. The system architecture and function are described in detail in this paper. The DCS control system presents a control-platform that can realize the configuration of the controlled objects in different regions at the same time. In any place with access to the internet, we can perform the parameter setting, real-time monitoring and remote fault diagnosis quickly using the presented DCS control system in any time. The system has the function of auto power on and shut down, and can adjust the temperature settings of the entire terminals automatically. The long-term operation performance shows that the energy conservation effect is very significant by using the Ethernet-based remote distributed control system.
