基于树莓派和云平台的智能花卉浇灌系统设计

Design of Intelligent Flower Irrigation System Based on Raspberry Pi and Cloud Platform

传统的花卉浇灌系统存在一系列问题,例如实时率差、远程控制能力不强、易被干扰等问题。针对上述问题,本文提出并设计了一种基于树莓派和云平台的智能花卉浇灌系统,该系统由Raspberry Pi(树莓派)中央控制单元、阿里云IoT(Internet of Things)平台、各种传感器、手机端App四部分组成。采用Wi-Fi网络和MQTT协议(Message Queuing Telemetry Transport),将树莓派采集到的环境数据上传到阿里云,实现数据在云平台的实时刷新和树莓派与阿里云的通信。采用阿里云旗下的生活物联网平台(飞燕平台)构建手机App(Application),将数据从云端转发到手机App,使得数据在手机上实时显示,并通过MQTT协议实现手机对树莓派的远程控制。

The traditional flower irrigation system has a series of problems,such as poor real-time rate,weak remote control ability,and easy interference.In response to the above problems,this article proposes and designs an intelligent flower irrigation system based on Raspberry Pi and cloud platform.This system consists of four parts:Raspberry Pi central control unit,Alibaba Cloud IoT(Internet of Things)platform,various sensor and mobile App.Using Wi-Fi network and MQTT protocol(Message Queuing Telemetry Transport),the environmental data collected by Raspberry Pi are uploaded to Alibaba Cloud,thus realizing the real-time refresh of data on the cloud platform and the communication between Raspberry Pi and Alibaba Cloud.Using Alibaba Cloud’s Life Internet of Things platform(Feiyan platform),a mobile app(Application)is established,and data can be transferred from the cloud terminal to the mobile App,so that the data is displayed on the mobile phone in real time manner,and the remote control of Raspberry Pi by mobile phone is achieved through the MQTT protocol.
