Intelligent Home Car System Design Based On Internet Of Things

With the progress of Internet of Things technology and the popularity of intelligent terminal equipment,the industries of modern intelligent market are promoted to be flourishing.At the same time,the living standards of people increased significantly and the living conditions and travel methods have undergone tremendous changes,which makes the technologies such as the Smart Home and the Internet of Vehicles market need to be changed and upgraded.Nowadays,the development of the entire Internet of things presents a trend of diversification,the cross-border integration of Smart Home and Internet of Vehicles will be a model of innovation breakthrough.The "Home" subsystem and the"Car" subsystem were combined into one.It is of great significance to mine and analyze a variety of data of the cloud server to achieve the integration of data exchange,namely,we can use one APP to achieve the management of the home and car.In this paper,ZigBee technology,OBD communication protocol and Android system have been studied and related experiments have been carried out in order to design a Smart Home and Car System which is in line with the practical application and development trend,which makes the aim of real-time management of household data and vehicle information be achieved.The main research contents of the paper:(1)The existing smart home system application model and Internet of Vehicles design program have been studied.The smart home and car system which can be divided into"Home" subsystem and "Car" subsystem is presented.Through the comprehensive utilization of ZigBee,WiFi,LTE and other technologies,the data of the two subsystems will be uploaded to the cloud server platform faster and efficiently to analysis and process big data.And then,the Android mobile terminal APP is designed to achieve real-time monitoring of the information of the home and car.(2)The key theories and techniques needed for the entire smart home and car system have been studied,including ZigBee technology,OBD resolution protocol,and Android application software.ZigBee technology is an important support technology for home wireless sensor networks,which mainly focuses on ZigBee network architecture,IEEE802.15.4 communication layer protocol and ZigBee application layer interface.In view of the present situation of OBD market and focus on a variety of analytical protocols,and fault code analysis software which can adapt to different types of vehicles has been designed independently based on the learning of the Android system related theoretical knowledge.(3)The smart home and car system has been designed.Firstly,make research on Z-stack protocol stack through transplanting protocol stack to CC2530 chip to achieve ZigBee module wireless data communication.Secondly,use GD32F107 embedded master chip to design seamless conversion GD gateway of ZigBee protocol and TCP/IP protocol.Thirdly,utilize the C language to achieve the drive on the chip peripherals.Finally,use OBD module to connect the car CAN to analysis a variety of automotive data of ECU and choose the Visual Studio 2008 as the development platform and Visual C++ as the development language to design and develop the software combined with the development needs and software operating platform.(4)The Smart Home and Car system terminal APP has been developed by the JAVA programming language and integrating the functions of each module after studying the developing and development of the software of the the smart home and car system.Finally,the thesis elaborates the whole process of hardware module design and software function development and realizes a Smart Home and Car system based on Internet of things.After repeated testing,the system can achieve remote monitoring and management of the data of the home and vehicle.It has the advantages of versatility,easy transplantation,and can be installed and used on the platform with Android operating system,which makes it have a higher market value.
