【摘要】：在社會發(fā)展日新月異的今天,人們奮斗目標(biāo)不僅為了生存,而是擁有美好的生活環(huán)境,希望賴以生活的家園能夠變得更加人性化、智能化、舒適化和安全化。因而智能家居是科學(xué)技術(shù)發(fā)展的產(chǎn)物,也是人們期盼已久的產(chǎn)物,承載著人類對美好生活的向往與追求�，F(xiàn)如今智能家居領(lǐng)域的研究不斷深入,然而概念炒作、兼容性差和開發(fā)成本高等問題無法避免。在這樣的形勢下,對基于FPGA的智能家居控制系統(tǒng)進(jìn)行了研究,本文涉及的智能家居系統(tǒng)不再采用傳統(tǒng)的DSP或者ARM,而是將FPGA作為該系統(tǒng)設(shè)計的控制中心。FPGA處理速度快,時序邏輯強(qiáng),I/O口數(shù)量眾多等一系列優(yōu)勢,致使它能夠為智能家居系統(tǒng)的穩(wěn)定運(yùn)行保駕護(hù)航。在本設(shè)計中利用Wi-Fi無線通信網(wǎng)絡(luò)提供遠(yuǎn)程操控,在家用電器設(shè)備與FPGA控制中心之間利用ZigBee無線通信網(wǎng)絡(luò)進(jìn)行信息的傳送。論文主要研究內(nèi)容如下:通過簡述智能家居行業(yè)的發(fā)展歷史、國內(nèi)外研究現(xiàn)狀以及發(fā)展趨勢,分析了系統(tǒng)的可行性。研究了系統(tǒng)整體框架和各模塊間通信的工作原理和選型,以及如何在智能家居控制終端上進(jìn)行后期的擴(kuò)展、與手持設(shè)備進(jìn)行家電控制信息的數(shù)據(jù)交換。研究了本設(shè)計中所需要使用的FPGA、QuartusⅡ集成開發(fā)環(huán)境、硬件描述語言、IP核以及Wi-Fi通信、ZigBee通信、RS-232串口通信和脈寬調(diào)制等核心技術(shù)并且對視頻監(jiān)控模塊中對改進(jìn)的混合高斯模型運(yùn)動目標(biāo)檢測算法以及摔倒檢測技術(shù)進(jìn)行深入探索。在研究理論同時完成了硬件設(shè)備的選型。在功能模塊中實現(xiàn)了串口通信模塊的數(shù)據(jù)正確接收,燈光控制模塊中對LED燈光亮度的調(diào)節(jié),家電控制模塊中對熱水器定時加熱控制,溫度測試模塊中對溫度實時檢測,危險氣體檢測模塊中對煤氣主要成分甲烷的檢測以及濃度超標(biāo)時進(jìn)行報警以及視頻監(jiān)控模塊中對有人摔倒時能夠及時發(fā)出報警并提醒家人進(jìn)行援助的功能。在對本系統(tǒng)的設(shè)計檢測中,首先利用串口調(diào)制助手對通信網(wǎng)絡(luò)進(jìn)行檢測以及運(yùn)用ModelSim對設(shè)計的模塊進(jìn)行仿真測試,其中在視頻檢測模塊中需要與MATLAB進(jìn)行聯(lián)合仿真測試。然后在確認(rèn)仿真無誤后進(jìn)行開發(fā)板運(yùn)行測試,經(jīng)檢測系統(tǒng)能夠在集成開發(fā)板上穩(wěn)定、無誤的運(yùn)行,完成了系統(tǒng)設(shè)計之初的要求。
[Abstract]:With the rapid development of society today, people's goal is not only to survive, but also to have a good living environment. We hope that the home on which we live can become more humanized, intelligent, comfortable and safe. As a result, smart home is the product of the development of science and technology, and it is also the product that people have been expecting for a long time, carrying the yearning and pursuit of human beings for a better life. Nowadays, the research of smart home is getting deeper and deeper. However, the problems of concept hype, poor compatibility and high development cost can not be avoided. In such a situation, the intelligent home control system based on FPGA is studied. The intelligent home system in this paper is no longer using traditional DSP or ARM, but FPGA as the control center of the system design. FPGA processing speed is fast. The number of I / O ports is numerous and so on, which can guarantee the stable operation of smart home system. In this design, Wi-Fi wireless communication network is used to provide remote control, and ZigBee wireless communication network is used to transmit information between home appliances and FPGA control center. The main contents of this paper are as follows: the feasibility of the system is analyzed by introducing the development history of smart home industry, the current research situation and the development trend at home and abroad. This paper studies the working principle and selection of the whole system frame and the communication between the modules, and how to extend the control terminal in the later stage and exchange the control information with the handheld device. The FPGA Quartus 鈪，
