摘要
目前，伴随着社会的进步与生产力的发展，尤其是科技水平的飞速提高，人们生活的品质发生了翻天覆地的变化，大家越来越重视生活的舒适度。随着嵌入式技术与自动控制技术的发展以及物联网世界的到来，智能家居产业迎来了发展的机会同时也面临着巨大的挑战，家居模式已经发生了翻天覆地的变化，各大电子厂商与科技公司都加入到智能家居的研究中来，智能家居市场竞争已经形成，促使智能家居产业的进一步发展。
本次毕业设计分析了国内外智能家居控制系统的发展过程，从开始的过于依赖PC机以及大多以有线通信为主，移动不方便到之后过度依赖WIFI通信，以WIFI技术为核心搭建的无线智能家居系统虽然是目前最优秀的智能家居解决方案，但是这种方案存在着功耗较大，有安全隐患等问题。
基于以上提出的智能家居控制系统方面的问题，本次毕业设计旨在设计一款基于可见光通信技术（Visible Light Communication，VLC）的智能家居控制系统。依靠白光LED作为发射端，以雪崩光电二极管作为接收端。其中，主机的核心控制器为STM32F407为平台，从机的核心控制器为STC15为平台，分别设计配套的PCB板，通过LED驱动电路，光接收电路等电路组成一个智能家居控制系统，可实现一些家居设备的控制。
本次毕业设计说明书首先对基于光通信的智能家居系统的总体方案设计，然后详细介绍各个模块的功能与使用情况，相关电路的设计与功能的仿真，主机与从机代码的编写思路。最后，对本次毕业设计系统中的节点与模块进行综合性的测试

Abstract
At present, with theprogress of society and the development of productivity, especially the rapidincrease in the level of science and technology, the quality of people's liveshas undergone earth-shaking changes. Everyone is paying more and more attentionto the comfort of life. With the development of embedded technology andautomatic control technology and the arrival of the world of the Internet ofThings, the smart home industry ushered in the opportunity of development andalso faced great challenges. The home model has undergone earth-shakingchanges, major electronics manufacturers and technology Companies have joinedthe study of smart homes, smart home market competition has formed, and promotethe further development of the smart home industry.
This graduationproject analyzes the development process of smart home control systems at homeand abroad. From the beginning, it relied too much on PCs and mostly wiredcommunication. After the inconvenience of mobility, it relied excessively onWIFI communication, and wireless intelligence was built with WIFI technology asthe core. Although the home system is currently the best smart home solution,there are many problems such as the power consumption and security risks.
Based on theabove-mentioned problems in the smart home control system, this graduationproject aims to design a smart home control system based on Visible LightCommunication (VLC). Rely on the white LED as the transmitter of information,and the Avalanche Diode as the receiver of information.Among them, the host's core controller is the STM32F407 as a platform, theslave's core controller is the STC15 as the platform, and the supporting PCBboards are designed respectively. The LED drive circuit and the light receivingcircuit form a smart home control system, which can realize some Home equipmentcontrol.
This graduationdesign specification firstly designs the overall scheme of the smart homesystem based on optical communication, and then introduces in detail thefunction and use of each module, the design of the relevant circuit and thesimulation of the function, and the preparation of the host and slave code.Finally, a comprehensive test of the nodes and modules in this graduationdesign system.
