[Abstract]:With the rapid development of science and technology and the improvement of people's living standard, smart home has come into people's life and is deeply loved. Intelligent home application wireless technology, automatic control technology and computer technology, through the mobile control terminal and home equipment interconnection and communication, to achieve intelligent equipment control. As an important parameter of household control, temperature plays a very important role in people's daily life, and its control is widely used in smart home industry. As the client of smart home control, mobile phone can receive and control the situation of monitoring point, which is not restricted by location. This paper describes the background and significance of the research in detail, analyzes the current situation and development situation of the smart home system at home and abroad, and discusses the key technologies of the intelligent home system. Through the analysis and research of home temperature, the intelligent home control system based on Android is designed and implemented, which mainly controls the indoor temperature to keep it at the optimum temperature value. Firstly, the design of temperature data acquisition is completed by analyzing the structure, composition and function of temperature acquisition module. The collection module uses the open source hardware platform raspberry pie as the central controller, the DS18B20 temperature sensor as the temperature acquisition module, and the Mysql database as the data storage platform. The functions of temperature acquisition, storage and display are realized. In the design and implementation of temperature control, lamp simulation heating system, DC motor simulation air conditioning system. Based on the temperature data collected by the DS18B20 temperature sensor, the measured temperature in the database is read and compared with the temperature value set by the mobile terminal, and the heating or air conditioning equipment is controlled by Python language to realize the temperature control. According to the characteristics of the controlled object, the mathematical model is established, and the PID algorithm is used to control the temperature. The model of room temperature PID control system is simulated and studied by MATLAB/Simulink software, and the optimal control parameters of PID are obtained in order to achieve the best control effect. Finally, the paper describes the design and implementation of Android application program in detail. By analyzing the collection and control of temperature, the data communication between mobile terminal and control gateway is completed, and the function of each module of APP is realized.
