Design Of Smart Home System Based On Single Chip Stm32

This paper aims to develop a smart home system based on Internet + mode.As we all known,the Internet + is another technological innovation after the computer,Internet and GSM innovations.This paper mainly studies the Internet + applications in terms of the Internet of things(smart home).This innovative approach has changed the current production mode and lifestyle of human through intelligent technology,emphasizing the convenience and practicality of life.In the process of customer’s long-time application,the Internet channel,platform and data analysis can be integrated into the whole system.And smart home in the future will be a new direction and development trend of household life.More and more people expressing requests on intelligent household during indoor-decoration,such as: lamp automatic control,automatic curtains,indoor door and window monitoring equipment and household appliances connected to the Internet.Furthermore,inspiring a certain function of above applications under certain conditions can provide the real,automatically light,automatic home water heater,automatic window and so on.This can provide comfortable life experience to customers.The using of wireless network technology in the control of the smart home can efficiently solve the problem of network lines and be helpful for the collaborative operation of the smart home devices.Therefore,this can greatly improve the transmission speed and simplify the safeguard function.With less wire,smart home would use the wireless network technology everyhere.In terms of some application special requirements of equipment,some mixed connections with Bluetooth can be used in order to protect the single transmission of audio transmission,avoiding distorting.In this design,the application of smart home individuals exchange information by connecting the STM32 through a variety of ways with network communication.After the exchange of information,the execution can be determined by judging instruction.So,people can monitor all kinds of electrical appliances and networking equipment in household.Through effective confirming of equipment on networking,it can exchange instructions to complete the assigned task from smart home system and so as to realize the overall usage of smart home.The processing of such information from STM32 is feedback to the customers through the handset.In other words,they can accept these information or issue commands through mobile phone APP or computers.We choose CC2430 chips as the wireless sensor network node.The design process of the whole circuit needs to integrate the whole module on a PCB board.With the thought of blocking,each original is block designed respectively by using ZigBee way for communication.This makes each piece of module can realize the combination of design.There are four sub-modules in this design,which is integrated in the motherboard,with infrared detection,light sensor,gas detection and temperature sensing.Through the ZigBee,signals transformed to the microprocessor for centralized processing.Through GPRS methods,signals are feedback to the user’s hands.This smart home system can accurately controls the real-time situation of the related areas at home and alarm dangerous in special circumstances.In order to avoid delays in the process of control of a large number of programs,we ensure the optimization of procedure in the hardware through the software and choose the STM32 series ARM processor chip.This software system use C language to write programs and the practical software is Keil.
