摘　　要：中央空调节能装置采用二级混合网络结构,在核心控制器中直接使用TCP/IP协议;而末端利用低成本的MODBUS协议实现,再通过网络控制器转换为TCP/IP协议后,再与服务器通信;其中,网络控制器采用ARM7+RTL8019AS实现;而末端采用AT89S52和MAX485实现;通过上述方案设计,实现了中央空调系统运行状态监视、实时控制、能源用量计量、系统故障诊断等功能,从而使系统整体节能效果达到较高水平。This energy saving controller for central air-conditioner （ESCCA） is made up of two level mixed network structures. TCP/ IP protocol is directly used inkernel controller, and low cost MODBUS protocol is used in Others. MODBUS protocol is transformed into TCP/IP protocol through network controller, and then the local devices can communicate with the server. ARM7 and RTL8019AS make up the network controller, AT89S52 and MAX485 make up others. According to this design, ESCCA is provided with many functions, such as monitoring running state, real-time control, energy cost calculation, exception handles, and so on, also the system can easily realize high --level purpose of saving energy.
