基于DSP控制的多联空调内外机通讯的研究

Study on the Communication of the Multi-connected Air-conditioner Indoor Unit and Outdoor Unit Based on DSP

采用DSP芯片控制室外机的多联空调机组,室内机往往采用单片机控制。通过对其内外机通讯系统的硬件和软件进行分析和研究,设计了一套控制方案。通过实验验证,通讯正确率可以达到98%以上,系统可以实时对用户要求做出反馈。

The micro-computer unit is used in the multi-connected air-conditioner indoor unit control system, while the DSP is used in its outdoor part. With the study on the hardware and the software in the communication of the multi-connected air-conditioner indoor and outdoor unit, the author designed a control system. Through the experiment, this system may make the realtime feedback to the user request, and achieve above 98% in the correct rate of communication.
