Design And Implementation Of Wireless Gateway For Smart Home Pension Based On STM32

Intelligent home care is a chip that adds the concept of the sensor network to the traditional electronic facilities of the elderly people,and connects all kinds of sensors and interconnected networks through intelligent perception and recognition technique,so that the aged will live int home and live under the monitoring of our computer.This article is devoted to creating a simple and practical control gateway system in the intelligent home care system.It marry the computer,electronic,communication and other technologies.It studies the gateway from the SCM,all kinds of sensors and software,and finally realizes the remote monitoring of the home environment for the elderly,and lets the elderly people.We can also enjoy the achievements of the development of science.On the hardware side,besides the peripheral circuit auxiliary modules such as power supply module and clock module,the STM32F4 chip which is the leading technology in the world is used as the core calculation of the hardware of the control gateway system.The data acquisition function of various terminal sensor nodes and two kinds of internal and external wireless communication are used.The combination of information technology and the completion of the intelligent home gateway system.At the time of selection,we choose the STM32F429IGT6 chip,which is powerful,easy to expand and low price.It is the brain of the whole information system to realize data analysis and intelligent control.The Zig Bee module selects CC2530 as the wireless technology for the internal networking of the equipment.The module mainly contains two pieces of content respectively.The module is composed of the coordinator module and the terminal node.The terminal nodes such as temperature and humidity,light,smoke sensor,temperature sensor and heart rate pulse sensor will process the data through Zig Bee,including the collection,packing and transmission of information data;the Wi-Fi module chooses the very high cost-effective ESP8266 Wi-Fi communication module in the industry,including the connection.And send hot features.The module is responsible for the interaction between internal control and external communication of the system,and then transmissions and receives information pass the Wi-Fi network.The key of intelligent home care gateway system is to prepare for the late stage of intelligent home care platform.When temperature,humidity,light intensity and smoke concentration are sensitive to family environmental data,and when the body temperature and pulse of the elderly are not in the normal range,the platform will collect data from a constant source,and make various processing decisions or transmissions to the corresponding service institutions and guardians through analysis and judgment.This subject is mainly to study the program code of hardware and driver hardware for intelligent home care,and the network debug assistant is convenient to test the transmission and reception of remote data.
