摘要
目前物联网智能设备种类繁多,但设备性能缺乏统一标准,对多物联网终端互联与控制造成了一定困难。因此提出MCMI与双路径并发的自动跳频Mesh组网方案,结合用户控制端,设计基于双向Sub-G的无线MESH智能家居控制系统。Mesh结构为3层终端间通信,第一层与第二层构成星形拓扑,第二层与第三层构成多连接树形,较之一般Mesh结构,更加简洁且降低了硬件要求。通过MCMI与双路径并发的信号传输方式,消除了无线网络信道干扰,信号稳定性提高50%。为应对各厂商协议不统一难以成为一个完整系统的问题,设计上层专有协议以克服技术差异化。该系统经过测试,运行稳定、性能优秀、可信赖度高,并且协议还预留自定义接口,拥有一定的拓展能力。
There are many types of IoT smart devices on the market today,and there is no certain uniform standard,which has caused some difficulties in the interconnection and control of IoT terminals.This system proposes a scheme of MCMI and dual-path concurrent automatic frequency hopping Mesh networking.Combined with the user control end,a wireless MESH smart home control system based on two-way Sub-G is designed.The Mesh structure in this paper is communication between three layers of terminals.The first layer and the second layer form a star topology,and the second layer and the third layer form a multi-connection tree.Compared with the general Mesh structure,it is more concise and reduces the hardware requirements.MCMI and dual-path concurrent signal transmission methods eliminate channel interference in wireless networks and increase signal stability by 50%。In order to cope with the inconsistency of the protocols of various manufacturers and become a complete system,a proprietary protocol at the upper layer was designed to solve the technical difference.This system has been tested and runs stably,with excellent performance and high reliability,and the protocol also reserves custom interfaces,which has certain expansion capabilities.
