摘要
本文介绍了RS-232及RS-485总线的基本通讯规则,阐述了基于RS-232及RS-485总线的网络空调控制系统组成,拟定了网络空调控制系统的基本通讯协议。通过具体实例介绍了编码数据的含义,简要论述了网络空调控制系统的功能。实践表明,基于RS-232及RS-485总线的网络空调控制系统性能可靠,功能完备,具有很大的推广应用价值。
This text introduces the basic communication rule of the RS-232 and RS-485 bus, elaborates the control system constitution of network air conditioner based on the RS C 232 and RS- 485 bus, drawing up the basic communicated protocol of the network airconditioner control system. The coded data meaning is introduced through the concrete example, briefly elaborated the network air conditioning control system function. The fact indicates that the network air- conditioner control system based on RS-232 and RS-485 bus has reliable performance and its function is complete, with very great generalized application value.
