【摘要】：为了降低多联机空调系统的成本、简化安装工程,采用电力线载波通信技术构建了多联机空调的通信系统。首先根据系统控制的通信需求提出了基于窄带电力线通信技术的解决方案;然后主要从信道接入控制和组网控制两方面设计了包括物理层、介质访问控制(MAC)层、网络层和应用层的四层通信协议集,提出了基于载波侦听多路访问/冲突避让(CSMA/CA)设计思想的三种信道接入算法以及星型网络拓扑的组网算法;最后对11节点多联机空调系统进行了组网测试、正常通信测试和抗干扰测试。测试结果表明所提算法及方案能够满足多联机空调系统的实时控制要求,并具有较强的抗干扰能力;另外,所设计的通信协议具有开放性,可以根据需求进行修改,应用于智能家居等短距离无中继的实时控制领域。
[Abstract]:In order to reduce the cost of multi-on-line air conditioning system, the installation project is simplified. The communication system of multi-on-line air conditioning is constructed by using power line carrier communication technology. Firstly, a solution based on narrow-band power line communication technology is proposed according to the communication requirements of system control. Then, four layers of communication protocol sets including physical layer, medium access control layer, network layer and application layer are designed from two aspects of channel access control and networking control. This paper presents three channel access algorithms based on the design idea of carrier listening multiplexing access / collision avoidance CSMA / CAA and a network algorithm based on star network topology. Finally, the network test, normal communication test and anti-interference test of 11-node multi-on-line air conditioning system are carried out. The test results show that the proposed algorithm and scheme can meet the real-time control requirements of multi-on-line air conditioning system. And has strong anti-jamming ability; In addition, the designed communication protocol is open and can be modified according to the requirement. It can be applied to the real-time control field of short distance and no succession in smart home.
