Intelligent Home Simulation System Based on Single Chip Microcomputer
[Purposes]In order to realize people-oriented concept,through the mobile phone terminal to control household equipment,this study aims to make people's life more comfortable and convenient.[Methods]Taking STC89 C52 single-chip microcomputer as the terminal of the control core,the embed-ded hardware design is adopted,and the related core technologies such as Bluetooth communication and Android are used.The HC-05 Bluetooth module is connected to the Android mobile phone to realize in-teractive communication.The mobile phone APP is used to send and receive information,and each sen-sor module and drive board are reasonably selected,so as to design a set of reasonable single-chip intel-ligent home simulation system.[Findings]The simulation system is divided into five space modules.And among them,the kitchen space module uses an independent single-chip development board and a liquid crystal display screen,which can display the current indoor temperature in real time.By setting the temperature threshold,the buzzer will sound an alarm when the temperature value read by the tem-perature sensor exceeds the threshold.The living room space module,the toilet space module,the bed-room space module and the door module all use the STC89C52 single-chip microcomputer minimum sys-tem connected with the mobile phone APP through the Bluetooth module(HC-05),which is used to control the LED light.The turn-off of the DC motor fan,the opening and closing of the curtain,and the switch of the door(SG90 steering gear).Among them,the L298N driver board is used to control the DC motor fan,and the ULN2003 driver board is used to control the stepper motor 28BYJ4.[Conclusions]By controlling the hard-ware equipment in the mobile terminal,the expected function can be achieved,which can effectively solve the problem of poor compatibility caused by the wide variety of household appliances in the smart home system,so as to realize the real-time control and efficient management of the smart home.
