摘　　要：为了实现对校园人口密集场所中多种环境质量指标数值的实时监测,设计了一种基于LwIP协议栈的校园环境监测平台。平台采用模块化设计,分为局域环境监测系统、数据处理转换中心与云平台,实现对各环境指标数据的采集、处理、传输、存储与显示。局域环境监测系统采用ESP8266模块开发,各模块间通过WiFi组成星型网络,实现多节点同时采集温湿度、CO、CO2、TVOC等指标数据,数据处理转换中心通过STM32芯片移植LwIP协议栈设计了一款串口转以太网网关,实现通过IPv6网络将数据发送至云平台,云平台可存储数据并以图形化的形式进行展示。In order to realize the real-time monitoring of multiple environmental quality indicators in densely populated places on campus,a campus environment monitoring platform based on the LwIP protocol stack is designed. The platform adopts a modular design and is divided into a local environmental monitoring system,a data processing conversion center and a cloud platform to realize the collection,processing, transmission, storage and display of various environmental indicator data. The local environmental monitoring system is developed with ESP8266 modules. Each module forms a star network through WiFi to realize multi-node simultaneous collection of temperature and humidity,CO,CO2,TVOC and other index data. The data processing conversion center uses STM32 chips to transplant LwIP protocol stack to design a serial-to-Ethernet gateway enables data to be sent to a cloud platform via an IPv6 network,which can store data and display it in graphical form.
