摘要
以物联网技术为核心,以Wi-Fi无线通信为通信手段,以云服务器搭建的WEB应用为应用门户,模拟设计出一款室内环境在线监测系统.系统采取物联网三层架构:感知层以STM32F103芯片作为控制核心,选用DHT11温湿度传感器、MQ-2烟雾气敏传感器、三线制光敏电阻传感器作为信息采集单元;网络层利用ESP8266低功耗Wi-Fi芯片实现数据交互;应用层基于Django框架搭建,实现实时环境数据的远程获取.实验结果表明,该系统能远程在线实时监测室内环境参数,具有安装方便、操作简单、成本较低等优点,有较好的应用价值.
An indoor environment online monitoring system was simulated and designed with Internet of Things technology as the core,Wi-Fi wireless communication as the means of communication,and WEB application built by cloud server as the application portal.The system adopted three-tier architecture of the Internet of Things.In the sensing layer,STM32F103 chip was used as the control core,DHT11 temperature and humidity sensor,MQ-2 smoke gas sensor and three-wire photoresistor sensor were selected as the information acquisition unit.The network layer used ESP8266 low power Wi-Fi chip to realize data interaction.The application layer was based on Django framework to achieve remote acquisition of real-time environmental data.The experimental results show that the design can monitor indoor environmental parameters online and remotely,and has the advantages of convenient installation,simple operation and low cost,so it has good application value.
