基于STM32的智能家居系统设计

Design of smart home system-Security system software developmentAbstractWith the coming of 5G era,the Internet of everything is about to become a reality,smart home also quietly enters into people's life,and our life style will changedramatically,become more convenient,become higher quality.Smart home is IOT'sresidential platform,which combines bus technology,wireless network technology,security technology,automatic control technology,audio and video technology andother technologies according to people's needs to build a high-quality and efficientdaily affairs and equipment management system.Compared with ordinary home,itnot only improves home safety,comfort,convenience,and environment also saves allkinds of energy costs.In this design,STM32 of crotex-m3 core is used as the upper computer of smarthome control system.The real-time information fed back by each sensor can beviewed through GUI interface,and the corresponding processing can be carried outaccording to these information through the operation of graphic interface.Most of themodules are driven by STC89C52 as the lower computer,and the security module isdriven by STM32.Between STM32 and AT89C52,the communication tool isesp8266 module,which uses IEEE 802.11 (WiFi)protocol to communicate.Thisthesis mainly describes the development of the security system in the smart home andthe specific process of the function realization of each related module.Finally,theGSM module,human infrared sensor,fingerprint identification module,cameramonitoring and other modules are used to realize the real-time alarm and remotemonitoring,and corresponding measures are taken in time to avoid the occurrence ofdisasters and casualties and ensure the property safety.Keywords:embedded;STM32;smart home;fingerprint recognition;remotemonitoring;GSM
