【摘要】：近年來(lái)隨著自動(dòng)化技術(shù)、電子信息技術(shù)和計(jì)算機(jī)技術(shù)的快速發(fā)展,尤其是在物聯(lián)網(wǎng)建設(shè)的推動(dòng)下,住宅的智能化越來(lái)越受到人們的關(guān)注。本課題通過(guò)對(duì)基于物聯(lián)網(wǎng)所構(gòu)建的智能家居系統(tǒng)的工作原理和能耗的分析,認(rèn)為要體現(xiàn)家居智能化,首先要解決家用電器的遠(yuǎn)程控制和節(jié)能控制,而空調(diào)能耗又較高,占家庭總能耗的約三分之一,所以在保證舒適的前提下降低空調(diào)能耗具有重要意義。 通過(guò)分析家用空調(diào)傳統(tǒng)控制方式高能耗的原因,研究了基于預(yù)測(cè)平均投票數(shù)(PMV)這種人體舒適度指標(biāo)的控制方法。通過(guò)研究影響PMV值的六個(gè)參數(shù)變量,得到房間溫度、房間濕度和室內(nèi)空氣流速對(duì)PMV值影響的曲線,并根據(jù)曲線具體變化規(guī)律,給出了節(jié)能控制算法。采用模糊控制理論設(shè)計(jì)了基于PMV值變化的模糊控制器,通過(guò)控制室內(nèi)溫度、濕度和室內(nèi)空調(diào)出風(fēng)口風(fēng)速來(lái)間接控制PMV值穩(wěn)定在舒適度范圍之內(nèi),通過(guò)節(jié)能算法在夏冬季分別采用不同的控制方法實(shí)現(xiàn)節(jié)能。 設(shè)計(jì)出一種應(yīng)用于建筑設(shè)備物聯(lián)網(wǎng)平臺(tái)的無(wú)線紅外轉(zhuǎn)發(fā)器,采用對(duì)碼學(xué)習(xí)和查詢學(xué)習(xí)這兩種方式對(duì)紅外遙控指令進(jìn)行學(xué)習(xí),實(shí)現(xiàn)了無(wú)線紅外轉(zhuǎn)發(fā)器對(duì)任何品牌空調(diào)的遠(yuǎn)程控制并在建筑設(shè)備物聯(lián)網(wǎng)環(huán)境下通過(guò)相關(guān)軟硬件設(shè)計(jì)實(shí)現(xiàn)了家用空調(diào)的控制。 設(shè)計(jì)實(shí)現(xiàn)了無(wú)線紅外轉(zhuǎn)發(fā)器與物聯(lián)網(wǎng)節(jié)點(diǎn)之間的無(wú)線通信接口及數(shù)據(jù)傳輸協(xié)議,并將基于PMV值變化的模糊節(jié)能算法通過(guò)在建筑設(shè)備物聯(lián)網(wǎng)節(jié)點(diǎn)配置及應(yīng)用驗(yàn)證了其有效性。用戶可以通過(guò)電腦、手機(jī)等終端在建筑設(shè)備物聯(lián)網(wǎng)平臺(tái)上設(shè)置空調(diào)相關(guān)控制參數(shù),設(shè)置的控制參數(shù)通過(guò)建筑設(shè)備物聯(lián)網(wǎng)節(jié)點(diǎn)最終下發(fā)到家中的無(wú)線紅外轉(zhuǎn)發(fā)器,從而實(shí)現(xiàn)對(duì)空調(diào)的節(jié)能控制。
[Abstract]:In recent years, along with the automation technology, the rapid development of electronic information technology and computer technology, especially in promoting the development of the Internet of things, intelligent residential more and more attention. The analysis of this topic through the intelligent Home Furnishing system built on the Internet of things based on the working principle and energy consumption, to reflect the Home Furnishing intelligence first of all, to solve the remote control and energy-saving control of household appliances, and air conditioning energy consumption is higher, accounting for about 1/3 of total household consumption, so it has important meaning to ensure comfort under the premise of reducing the energy consumption.
Through the analysis of the reasons for household air conditioning the traditional control method of high energy consumption, the number of predicted mean vote (PMV) control method based on the human comfort index. Through the study of six parameters that affect the value of the variable PMV, room temperature, humidity and air velocity in room PMV value curve, and according to the curve of concrete change control algorithm of energy saving are presented. Using the fuzzy control theory to design a fuzzy controller based on the change of PMV value, by controlling the indoor temperature, humidity and indoor air outlet velocity to indirectly control the stable PMV value within the comfort range, to achieve energy-saving control method through energy saving algorithm in summer and winter are different.
The design of a wireless infrared transponder used for building equipment networking platform, using the code of learning and inquiry learning of these two ways of learning infrared remote control instructions, realize remote control wireless infrared transponder for any brand of air conditioning and building equipment in the network environment through the relevant hardware and software design to achieve the control of household air conditioner.
The design and implementation of wireless communication interface and data transmission protocol between wireless infrared transponder and networking nodes, and through building equipment configuration and application of network nodes to verify the validity of the fuzzy algorithm based on such PMV value change. Users can use computer, hand machine terminal in the construction equipment networking platform is provided with air conditioning the control parameters, control parameters set by construction equipment networking nodes finally issued home wireless infrared transponder, so as to achieve energy-saving control of air-conditioning.
