Design And Implementation Of Intelligent Control System Of Automobile Air Conditioner Based On Internet Of Things

With the improvement of people’s living standards and the rapid development of science and technology,people have higher and higher requirements for the comfort of the car environment when using cars.As a car air conditioning control system that regulates the car environment,it is also in the context of technological development.Performance has been continuously improved.The automobile air conditioning control system mainly improves the environment in the car by controlling factors such as temperature and air flow rate.The various sensors installed in the car are used to obtain environmental data during the operation of the car’s air-conditioning,and based on this data,the calculation process is performed and the relevant actuators are controlled to keep the environment in the car in the most comfortable state for the human body.The Internet of Things technology is the communication between things realized on the basis of the Internet.It realizes data interaction through terminal equipment,network service technology and application service technology.Load related hardware on the car so that the car-side control equipment can use various sensors on the car to collect environmental data in the car,transmit the data to the cloud server through the Internet,and perform statistical analysis on the data based on the uploaded data,and feedback to the user in real time about environmental data in the car.This article mainly studies the automotive air-conditioning control system based on the Internet of Things,using the Ali-Cloud platform as the cloud server platform to realize the control of the actuator and the collection,calculation and processing of important environmental parameters such as temperature and blower speed in the car-side air-conditioning control system,To realize the environmental protection of the automobile air conditioning control system and improve the comfort of the occupants.Establish a connection between the car terminal and Ali-Cloud,so that the data collected by the car terminal can be uploaded to Ali-Cloud in real time,and statistical analysis is performed on the cloud platform,and real-time feedback to the user’s car environmental conditions.Compared with the traditional automatic air-conditioning system,the car air-conditioning system integrated with the Io T technology can not only provide real-time feedback to the user’s car environmental data,but also collect a large number of user-preferred car environmental data to form a huge the database is used as the data basis for the development of intelligent control system for automobile air-conditioning.The research object of this article is mainly divided into three parts:one is the research on the algorithm of the car air-conditioning blower;the second is the software design and implementation of the car-side controller and data collector;the third is the data calculation and processing on the Ali-Cloud Io T platform And real-time monitoring of data.The main tasks are:First of all,starting from the experimental purpose of green energy saving and ensuring comfort,the main control algorithm of automobile air-conditioning blower is studied.Combining the control algorithms of existing automobile air conditioners and analyzing the advantages and disadvantages of various algorithms,on the basis of taking into account the advantages and disadvantages of various algorithms,an improved green and energy-saving blower control algorithm is proposed and established on the MATLAB platform the mathematical model of the algorithm is simulated and verified.Secondly,in order to complete the functions from the hardware platform of the data to the experimental data acquisition and cloud server data monitoring,the Internet of Things technology,hardware and software design involved in the experimental function are introduced,and the selection and related design of the cloud service platform;according to actual conditions and design requirements for hardware module selection,and a detailed introduction to the performance and working principle of the selected hardware components,and then build a car-side hardware experiment platform;after the hardware platform is built,design the program flow chart of each module function,and write the function Software program to achieve the purpose of experimental design.Then,the data is obtained through the Internet of Things platform to verify the accuracy of the experimental data and overcome the obstacles of the difficulty of car unit data.After the realization of the functions of the various modules of the car hardware and the access to the Ali-Cloud platform,a one-to-one correspondence with the car data is built on the Ali-Cloud Io T platform,and the data uploaded to Ali-Cloud is stored,calculated and processed.In order to realize the real-time monitoring function,build the Web and APP terminal on the Io T platform to realize the real-time monitoring function of data.Finally,after achieving the above functions,this article will test and verify the functions designed in the experiment one by one.Relevant software is used to test the realization of the simulation model,the functional test of each module of the hardware platform,and the data processing and real-time monitoring on Ali-Cloud’s Io T platform to verify whether the function of the experimental design meets the expectations of the experimental design.
