摘要
本文设计了一套用于科学考察的测量船的大型中央空调的控制系统。该系统采用适合现场控制的小型PLC实现对空调箱及压缩机组的现场控制，以工业以太网技术实现不同压缩机组及空调箱之间的通讯，并采用监控与数据采集系统（SCADA）实现整个空调系统的集中远程控制及状态监控。
The paper designed and realized the central air conditioning system＇ s control system mounted on scientific survey ship. The air conditioning compressor units and air handling unit are controlled by the PLC based control system. The controlling and monitoring of the whole system is through the application of Supervisory Control and Data Acquisition （SCADA） system.
