Research And Implementation Of Indoor Electric Heating Control System Based On Internet Of Things

The heating methods in urban areas in northern China are mainly central heating.In rural areas and in central and southern areas,central heating is not implemented.In winter,heating demand can only be solved by burning coal or air conditioning.With the improvement of people's living standards,people's demand for warm comfort and convenience in winter is getting higher and higher,so the market has a strong demand for a comfortable way with high comfort,high convenience and good economy.Therefore,the geothermal film type electric heating appeared on the market.The principle is that the electric heating film is placed under the floor,and the heat is supplied by the heating wire to solve the above problems to some extent,but there is still a large power consumption and cannot store heat.The heating wire heats the indoor drying and other shortcomings.In recent years,there have been energy-saving electric heating devices on the market.The principle is similar to that of electric water heaters.The electric energy is used to heat the water,store it,and then use the peak-to-valley electricity price difference to save electricity.Energy storage type electric heating solves the problem of some geothermal film type electric heating,but it is still insufficient in convenience.If the user can view the indoor temperature and system working status remotely and in real time,and at the same time set the working parameters such as the target temperature,the convenience,user experience and work efficiency will be greatly improved.This paper introduces the design and implementation process of an IoT-based control system that uses cloud service and IoT technology combined with an energy storage electric heating device to improve the electric heating system.The application can remotely view the current indoor temperature and the working state of the electric heating device in real time.At the same time,the working parameters of the electric heating system can be set,and the system automatically controls according to the setting,thus realizing remote real-time monitoring of the electric heating device by the user..The control system is based on the STM32 microcontroller and uses a Wi-Fi module to connect to the server via a wireless LAN,thereby indirectly connecting to the application of the mobile phone.On the one hand,the microcontroller receives parameters such as temperature and humidity collected by various sensors and sends them to the client via the server to realize real-time display of the indoor environment and system working status to the user;on the other hand,the user sets relevant parameters to be sent to the micro control via the server.The microcontroller controls the energy storage type electric heating working device according to the parameters set by the user and the parameters collected by the sensor,thereby realizing remote control of the system by the user.In this way,the current energy storage electric heating system is improved to meet the demand for improving convenience and user experience.
