【摘要】：信息技術(shù)的發(fā)展、人們生活水平的提高以及席卷中華大地的房地產(chǎn)開發(fā)熱潮,激發(fā)了強(qiáng)烈的智能家居市場(chǎng)需求。本文從家庭電力線路以及家居設(shè)備的布局情況出發(fā),提出了一套以電力線通信(PLC)技術(shù)為基礎(chǔ),由PLC網(wǎng)關(guān)、集中控制器、PLC節(jié)點(diǎn)三種模塊組成的智能家居系統(tǒng)解決方案。對(duì)內(nèi)能夠?qū)崿F(xiàn)溫濕度等傳感數(shù)據(jù)采集、燈光控制、電器控制等功能,對(duì)外能夠通過PLC網(wǎng)關(guān)實(shí)現(xiàn)Internet遠(yuǎn)程訪問。 除完成上述模塊的硬件電路設(shè)計(jì)外,本文對(duì)電力線通信協(xié)議設(shè)計(jì)進(jìn)行了重點(diǎn)研究。結(jié)合系統(tǒng)選用的載波芯片M1200E的特點(diǎn),提出了CSMA/CA協(xié)議與802.1le中的時(shí)隙退避思想相結(jié)合的電力線MAC接入?yún)f(xié)議,提高了電力線信道利用率。針對(duì)電力線網(wǎng)絡(luò)惡劣的通信環(huán)境提出了一種利用Hello肖息改進(jìn)AODV的備份路由協(xié)議——AODV-IB,該協(xié)議使得節(jié)點(diǎn)能同時(shí)維護(hù)主路由與備份路由,并在主鏈路斷裂時(shí)可以“零延時(shí)”的啟用備份路由進(jìn)行快速恢復(fù)。通過搭建的基于電力線通信網(wǎng)絡(luò)的測(cè)試平臺(tái),對(duì)相關(guān)協(xié)議測(cè)試后,證明AODV-IB在減少延時(shí)、提高數(shù)據(jù)包投遞率方面改進(jìn)效果顯著,更加適合在電力線通信網(wǎng)絡(luò)中使用。同時(shí),本文還對(duì)PLC節(jié)點(diǎn)自組網(wǎng)、WEB服務(wù)器搭建等工作進(jìn)行了介紹。
[Abstract]:With the development of information technology, the improvement of people's living standard and the upsurge of real estate development sweeping across China, the strong demand of smart home market has been aroused.Based on the layout of home power line and home equipment, this paper presents a solution of intelligent home system based on power line communication (PLC) technology, which consists of three modules: PLC gateway and centralized controller.The functions of temperature and humidity sensing data acquisition, lighting control, electrical control and so on can be realized internally, and Internet remote access can be realized through PLC gateway.In addition to the hardware circuit design of the above modules, this paper focuses on the design of power line communication protocol.Considering the characteristics of the carrier chip M1200E, a power line MAC access protocol based on CSMA/CA protocol and time-slot Backoff in 802.1le is proposed, which improves the power line channel utilization ratio.A backup routing protocol (AODV-IBS), which uses Hello information to improve the backup routing of AODV, is proposed for the poor communication environment of power line network. This protocol enables nodes to maintain both primary and backup routes simultaneously.And when the main link breaks, the "zero-delay" backup route can be enabled for fast recovery.Through the test platform based on the power line communication network, it is proved that AODV-IB can reduce the delay and improve the packet delivery rate, which is more suitable for use in the power line communication network.At the same time, this paper also introduces the construction of Web server for PLC nodes.
