Design Of Intelligent Rural System Based On Internet Of Things

Intelligent countryside is a new concept different from intelligent city.It refers to the modernization,intellectualization of rural residents' life and production,with the goal of building a new socialist modern countryside and using the relatively mature Internet of Things technology,so as to improve the living standards of rural residents and establish their own intelligent life value system.Intelligent countryside generally includes four modules: intelligent agriculture,smart home,smart grid and intelligent transportation.The intelligent countryside system based on the Internet of Things proposed in this paper mainly focuses on the research and design of smart agriculture and smart home.The intelligent agriculture module uses a variety of sensor equipment and ZigBee wireless transmission function to monitor environmental data in agricultural greenhouse,including air temperature and humidity,carbon dioxide concentration,light intensity and soil temperature and humidity.It also realizes remote control of water pumps,fans and curtains in greenhouse.The collected data can be viewed in real time on the mobile client and controlled by the corresponding devices.The smart home module mainly realizes the remote control of household equipment and the monitoring of household environment as well as the detection of health data of the elderly.It enables rural residents to control household appliances,curtains and lamps remotely through mobile phone clients,and real-time monitoring of smoke concentration,air temperature and humidity in the household environment,so as to make daily life more convenient and safe for residents.The elderly health data monitoring is mainly designed for the health problems of the elderly in rural areas.It can monitor the vital signs of the elderly,such as blood pressure,blood oxygen concentration,heart rate and body temperature,and upload the collected data to the mobile phone client,so as to grasp the health status of the elderly.The software part of smart countryside system is developed on Android platform,which enables users to query and control data remotely on Android mobile terminal.The hardware part mainly includes gateway platform and bottom sensor node.The main control chip of gateway platform uses STM32F407 high-performance microcontroller and LCD touch display screen to facilitate users to perform related operations on the touch screen.The bottom sensor node is mainly composed of various wireless sensor devices and ZigBee wireless transmission module to form a wireless sensor network,which will transmit all kinds of data.The data information collected by sensor node is transmitted to ZigBee coordinator node through transmission module and sent to the corresponding gateway server.Finally,the gateway platform server establishes a Socket connection with the user's terminal device software to communicate in real time,so that users can query and share relevant data through various terminal devices such as mobile phones and tablets,and also to the underlying layer.The device sends control instructions.
