基于NB-IoT的空调远程控制系统设计及实现

　　一种基于窄带物联网(NB-IoT)技术的空调远程控制系统方案，实现了客户端对空调的远程监控。给出了以STM32为主控制器、以NB-IoT技术为核心、以OceanConnect开发者平台为支撑的系统总体框架，阐述了系统硬件、软件设计思路，制定了空调与主控制器之间、主控制器与云平台之间的通信协议，实现了空调、云平台、移动客户端三者之间的信息交互。测试结果表明，该系统稳定可靠，数据通信实时性好，为将来空调的智能化控制、管理及大数据分析提供技术基础。

　　Abstract:

　　A scheme of air conditioning remote control system based on narrowband Internet of things (NB-IoT) technology is proposed,which realizes the remote monitoring of air conditioner by clients.The overall system framework with STM32 as the main controller,NB-IoT technology as the core,and OceanConnect developer platform as the support was given.The design ideas of hardware and software were elaborated,the communication protocols between the air conditioning and main controller,and between the main controller and the cloud platform were formulated.The information interaction among the air conditioner,the cloud platform and the mobile client was realized.The test results show that the system is stable and reliable,real-time data communication is good,and provides a technical basis for intelligent control,intelligent management and big data analysis of air conditioning in the future.
