Remote Intelligent Irragation System Based On STM32

With the rapid development of the technology of Internet,the promotion of smart home has been unstoppable.With the improvement of people's living standards,planted ornamental plants at home balcony has became a pursuit of elegant way of life.In order to solve the inconvenience when travel,a remote intelligent irrigation system is designed,which combined the technology of embedded,Internet and smart phones.This system achieves the prupose of remote irragation.Firstly,this paper describes the current situation of remote irrigation system,and put forward the overall design of the system accordingly.In this paper,the technology of hardware platform of STM32,embedded technology,web camera technology and Wi-Fi technology are introduced.Secondly,the hardware circuit of the whole embedded system is divided into five modules according to the modular design idea,namely STM32 main control module,sensor module,solenoid valve drive module,Wi-Fi communication module and the web camera module.The circuit schematic diagrams of each module are designed,and the PCB layout and the welding of prototype machine are completed.Thirdly,the advantages and disadvantages of the mainstream embedded operating system are analyzed.The open-source RT-Thread operating system is selected and transplanted.Based on RT-Thread,the underlying driver programs,remote communication program and intelligent irrigation program are designed.In order to support Chinese characters display in the entire system,the FATFS file system is transplanted.Finally,the prototype machine of the whole system is tested by hardware and software,and the rationality and feasibility of the system were verified in the laboratory taking remote watering flower as an example.
