Design Of Smart Home Control Device Based On Raspberry Pi And Cloud Platform

With the improvement of the quality of people's living standards,people have put forward more intelligent and convenient requirements for the living environment.In recent years,Internet of things technology has developed very rapidly.In order to meet people's demand for smart homes,many manufacturers have launched their own smart home hardware and Internet of things cloud platform.In this paper,based on the background of smart home,combined with humanized needs,a smart home control device based on Raspberry Pi and cloud platform is designed.Through the Internet of things cloud platform,the indoor environmental parameters can be monitored in real time,and the intelligent terminal can be controlled in both directions.This design includes three parts: indoor environment detection module,Internet of things cloud platform and home control device.As an intelligent terminal of the Internet of things,the indoor environment detection module collects environmental parameters,such as light,temperature,humidity and other parameters.The sensor is connected to the cloud platform of the Internet of Things through a WiFi chip to upload the collected data;The Internet of things cloud platform provides a safe and reliable connection and communication capability for the device,and can provide a cloud API upward,and the instruction data is sent to the device through the API call to achieve remote control;Home control device,with Raspberry Pi as the main control chip,as the core part of the whole design,connect the microphone and speaker to develop the function of intelligent voice.Not only can communicate with people normally,but also follow instructions to control smart homes,etc.,connect cameras,develop face recognition functions,carry out identity authentication to improve the safety and reliability of smart homes,connect display screens,develop human-computer interaction functions,and make interaction more visual.The device designed in this paper can expand multiple sensor nodes in the indoor environment detection module to meet the needs of different smart home scenes.The Internet of things cloud platform serves as a hub to connect the indoor environment detection module and the intelligent home control device in a wireless manner.The smart home control device with the Raspberry Pi as the core can improve the intelligent needs by fully utilizing the relatively powerful performance of the Raspberry Pi,on the basis of completing the above-mentioned functional requirements,the design of the paper can look forward to realizing more ideas in the future life and study.In this paper,The smart home control device based on the Raspberry Pi designed completes the principle of intelligence,convenience,safety and reliability,and at the same time reduces the manufacturing cost,under the implementation scheme of the existing smart home control device,a good solution is proposed.
