摘要

采用模块化设计思想对物联网节点进行逻辑抽象，将节点的功能和控制逻辑进行原子拆分，原子功能模块可根据不同场景自由组合部署，支持单一系统和分布式系统部署，具有可插拔和易于扩展的特性，满足物联网应用多元化的设计需求。设计并实现了基于该思想的轻量级物联网节点管理软件，测试该软件实际运行最小仅需要14 872 byte的flash和1 976 byte的RAM空间，可应用于硬件资源比较有限的场合。采用该软件框架设计了物联网智慧酒店客控系统包括基于ESP32（Wi-Fi Soc）的语音网关节点和基于CX32L003（MCU）的4位按键面板节点。基于该软件框架设计的客控系统可实现单次设计多酒店部署，解决了传统客控系统针对不同酒店应用场景无法通用，需要反复定制修改的问题，极大加快了酒店智能化部署进程。目前该客控系统已经在希岸、涂派等快捷酒店部署并稳定运行。

Abstract

The modular design idea was used to abstract the logic of IoT nodes

and the function and control logic of nodes were divided into atoms

the atomic modules can be freely combined and deployed according to different application

they support single system and distributed system deployment

and were pluggable and easy to expand

meet the diversified design needs of IoT applications.The design and implementation of lightweight IoT node management software based on this idea were described in detail.The test results show that the software only needs 14 872 byte of flash and 1 976 byte of RAM

which can be used in limited hardware resources.This software framework was used to design smart hotel RCU(room control unit)

including the design of voice gateway node based on esp32 (Wi-Fi SOC) and 4-bit key panel node based on cx32l003 (MCU).The RCU designed with this software framework can deploy to different hotels only needed to be designed once

which solves the problem that RCU cannot be used in different hotels and needs to be designed and modified repeatedly

and greatly speeds up the process of smart hotel deployment.At present

the RCU has been deployed and operated stably in Xi'an

Tupai and other express hotels.
