嵌入式控制的智能家居系统设计——树莓派实现

Linux based single-board computer. In this project, I designed a smart home controller using Raspberry Pi. The project starts with a comparison of three different network TVs available in the market, which leads to the selection of Raspberry Pi as the main component for the project. The document then introduces basic knowledge about Linux operating system, followed by two methods of application development on ARM/Linux platform: utilizing existing system resources and writing programs using C or Python. Next, the document demonstrates the use of GPIO (General Purpose Input/Output) pins on Raspberry Pi by controlling an LED. This showcases the various possibilities of local applications such as establishing a home wireless network and configuring network TVs. Furthermore, basic network protocols such as TCP/IP are briefly introduced. Based on this, the advantages and disadvantages of five different servers are compared, and the process of exposing our server to the external network is described. Additionally, two methods of implementing remote video surveillance are presented and compared. Lastly, the document discusses the establishment of software sources and its significance. The conclusion provides a detailed overview of the author's overall understanding of the entire platform.
