Design of Smart home based on Linux (1)

Written in front: do a half-yearly graduation design, find the work with this completely unrelated, found themselves now have to write not reconciled, but I still pay attention to this aspect of development, their own groping and help me to complete the smart home part, hope this can give some beginners can some convenience, after all, technology is an open, Not belonging to a certain person.

Summary

The main purpose of this topic is to design and implement a smart home system based on Linux development platform. This system mainly uses the PVC board to make the household model. The system hardware uses the ARM architecture of Samsung S3C6410 Chip made of OK6410 Development Board for handheld terminals, using ZigBee to achieve network communication, and combined with a variety of electronic components. Software design to Ubuntu12.04 system as a development environment, from the embedded bottom to the application layer of the development process, design a human-computer-friendly interface, to achieve the home environment monitoring and home appliances control, such as the realization of a fairly accurate temperature and humidity control, lighting control, curtains, such as automatic controls.

This paper introduces the hardware component of the intelligent Home system based on Linux, the process flow chart of each module, the detailed method steps of the development environment, the related software design and the final result.

This topic in the Intelligent home design and research and development has done a considerable effort to achieve a number of automatic control functions, for further research and development based on Linux smart home laid the foundation for the back of the study and research and development related topics is a good reference. This development environment can give any user who has a virtual machine installed, no need to re-build the environment, greatly saving the time of research and development work.

Abstract

The main purpose of this thesis are to design andimplement a smart home system based on Linux development platform. This systemmainly uses household model made of PVC panels. The hardware of this system adoptOK6410 Development Board based on ARM architecture made of Samsung ' s s3c6410chip as the H Andheld terminal, using Zigbee to achieve communication and combiningwith various electronic components. The software design takes the Ubuntu12.04system as the development environment, from the embedded bottom to theapplication Layer development flow, designs a man-machine interactive friendlyinterface, realizes monitor of family environment and T He control of homeappliances, such as the realization of the automatic quite accurate temperatureand humidity control, Lig Hting control, curtain automatic control.

This paper introduces the hardware composition part ofthe smart Home system based on Linux, each module program flow chart , thedetailed method and steps of building the development environment, the softwaredesign and the final results.

This issue in the design and development Ofintelligent home made considerable efforts, successfully implement Theautomatic control function, for further and development of the smart homebased on Linux to lay a foundation, for behind Learni NG and related tothe topic is a very good reference. This development environment can give anyuser with a Vsan, no re build environment, greatly save the time OfR & Amp D work.

Introduction

With the rapid development of information and network, intelligence has become an irresistible trend. Smart home first appeared in the United States, to residential for the application platform, both communication network, home appliance control, information and entertainment functions [1]. Through smart home, people can more effectively allocate personal time, life is more efficient. For example, through the video surveillance system, can greatly increase the safety of home life. In addition, through remote home appliances control, can be a great degree of convenience to people's lives, and to a certain extent, save energy. [2] Intelligent home control systems can also be used to regulate the temperature, humidity and air in the room to improve air quality and provide modern means of communication and information services.

Smart home in recent years has been fired in full swing, all kinds of intelligent community, Intelligent District, automatic call system, smart meter reading, smart appliances, smart Butler, etc., also springing up to the market. At the same time, smart home is also a national modernization of the construction of a embodiment, including the art of architecture, interior art decoration, the concept of life, information technology, electronic science and technology, sensor technology, automatic control technology and other modern technology perfect combination [3]. Smart home is not only a country's economic strength, people's living standards, science and technology, one of the comprehensive mark, but also will be the pursuit of human society housing a goal [4]. However, in fact, the current smart home is mostly in the system of high cost, long design cycle, technical standards are not unified, and China's smart home system is still in the initial stage, there are many technical problems to be solved urgently, the cost of development needs to be reduced, so that more people can enjoy the benefits of such science and technology. The industrialization, process, standardization, cheapness, safety and energy-saving of smart home products will be the direction that research and development workers pursue [5].

Therefore, to strengthen the design of smart home, how to choose the technology, how to select the best solution in a number of programs, and how to implement the design into the actual application, and then set up a perfect from the requirements to design to implementation and evaluation of the system has become a very important thing. This subject is in this context, emerged.

Based on the existing intelligent home system, this paper analyzes the present situation and future development trend of IoT intelligent home system at home and abroad, puts forward a design scheme combining ARM architecture processor and ZigBee wireless technology, and integrates the Internet communication technology. Realize remote control and management of intelligent home system in real time. The main contents of the work are:

(1) Build a smart home development environment based on Linux;

(2) The temperature and humidity testing and automatic control;

(3) To achieve the control of light;

(4) Realize automatic curtain control;

(5) Realize the access control system.
