【正文】 摘 要 介紹了語音遙控的電動小車的機(jī)械結(jié)構(gòu)及控制部分 .在機(jī)械結(jié)構(gòu)上 ,對普通的玩具小車做了改進(jìn) ,使小車的轉(zhuǎn)向更加靈活 ,并且在設(shè)計(jì)范圍內(nèi)可以實(shí)現(xiàn)任意角度轉(zhuǎn)彎和任意速度移動 。而在控制系統(tǒng)部分 ,則采用語音控制方式 ,使小車可以 聽懂 人的命令 ,娛樂性和互動性更強(qiáng) . 該小車各部分采用模塊化設(shè)計(jì)，各個模塊之間獨(dú)立性強(qiáng)。控制部分采用可編程微處理哭器，可以在不增加系統(tǒng)硬件的情況下方便地對系統(tǒng)進(jìn)行二次開發(fā)。本文對一輛小車進(jìn)行了實(shí)驗(yàn)，實(shí)驗(yàn)結(jié)果表明，語音識別系統(tǒng)在低噪聲環(huán)境中識別率很高，在噪聲水平較高的場合，識別率有所下降。小 車反應(yīng)靈敏。 關(guān)鍵詞：語音識別 單片機(jī) 智能小車 電機(jī)驅(qū)動 ABSTRCT Introduced the pronunciation remote control electrically operated car mechanism and the control section. In the mechanism, has made the improvement to the ordinary toy car, causes the car to change nimbly, and may realize the random angle curve and the free velocity migration in the design scope。 But in control system part, then selects the voice control method, enables the car to be possible to understand the person39。s order, the entertainment and interactive is stronger. This car various part uses the modular design, between each module control section uses programmable micro processing to cry, may in not increase the system hardware in the situation conveniently to carry on the redevelopment to the article carried on the experiment to a car, the experimental result had indicated that, the speech recognition system distinguished in the low noise environment rate is very high, in the noise level high situation, the recognition rate had the car response is keen. Key word: Speech recognition monolithic integrated circuit intelligence car motordriven 目 錄 緒 論 ........................................................................................................................... 4 1 總體方案 ..................................................................................................................... 5 方案論證 ........................................................................................................... 5 總體方案圖 ....................................................................................................... 5 系統(tǒng)工作原理 ................................................................................................... 5 2 硬件設(shè)計(jì) ..................................................................................................................... 6 語音識別模塊 .................................................................................................. 6 電機(jī)驅(qū)動模塊 ................................................................................................ 10 紅外檢測模塊 ................................................................................................ 11 鍵盤電路 ........................................................................................................ 11 主控芯片 8051 模塊 ...................................................................................... 12 單片機(jī) 的電源設(shè)計(jì) ............................................................................... 12 單片機(jī)復(fù)位電路 ................................................................................... 15 3．軟件設(shè)計(jì) ................................................................................................................ 16 主程序 ............................................................................................................. 16 監(jiān)控程序 ......................................................................................................... 17 語音訓(xùn)練程序 ................................................................................................. 20 鍵盤掃描程序 ................................................................................................ 21 電機(jī)驅(qū)動程序 ................................................................................................. 22 延時程序 ........................................................................................................ 24 程序清單： ................................................................................................
