摘要
目前，伴隨著社會(huì)的進(jìn)步與生產(chǎn)力的發(fā)展，尤其是科技水平的飛速提高，人們生活的品質(zhì)發(fā)生了翻天覆地的變化，大家越來(lái)越重視生活的舒適度。隨著嵌入式技術(shù)與自動(dòng)控制技術(shù)的發(fā)展以及物聯(lián)網(wǎng)世界的到來(lái)，智能家居產(chǎn)業(yè)迎來(lái)了發(fā)展的機(jī)會(huì)同時(shí)也面臨著巨大的挑戰(zhàn)，家居模式已經(jīng)發(fā)生了翻天覆地的變化，各大電子廠商與科技公司都加入到智能家居的研究中來(lái)，智能家居市場(chǎng)競(jìng)爭(zhēng)已經(jīng)形成，促使智能家居產(chǎn)業(yè)的進(jìn)一步發(fā)展。
本次畢業(yè)設(shè)計(jì)分析了國(guó)內(nèi)外智能家居控制系統(tǒng)的發(fā)展過(guò)程，從開(kāi)始的過(guò)于依賴PC機(jī)以及大多以有線通信為主，移動(dòng)不方便到之后過(guò)度依賴WIFI通信，以WIFI技術(shù)為核心搭建的無(wú)線智能家居系統(tǒng)雖然是目前最優(yōu)秀的智能家居解決方案，但是這種方案存在著功耗較大，有安全隱患等問(wèn)題。
基于以上提出的智能家居控制系統(tǒng)方面的問(wèn)題，本次畢業(yè)設(shè)計(jì)旨在設(shè)計(jì)一款基于可見(jiàn)光通信技術(shù)（Visible Light Communication，VLC）的智能家居控制系統(tǒng)。依靠白光LED作為發(fā)射端，以雪崩光電二極管作為接收端。其中，主機(jī)的核心控制器為STM32F407為平臺(tái)，從機(jī)的核心控制器為STC15為平臺(tái)，分別設(shè)計(jì)配套的PCB板，通過(guò)LED驅(qū)動(dòng)電路，光接收電路等電路組成一個(gè)智能家居控制系統(tǒng)，可實(shí)現(xiàn)一些家居設(shè)備的控制。

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.
