【正文】 摘 要 介紹了語(yǔ)音遙控的電動(dòng)小車(chē)的機(jī)械結(jié)構(gòu)及控制部分 .在機(jī)械結(jié)構(gòu)上 ,對(duì)普通的玩具小車(chē)做了改進(jìn) ,使小車(chē)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(dòng) 。而在控制系統(tǒng)部分 ,則采用語(yǔ)音控制方式 ,使小車(chē)可以 聽(tīng)懂 人的命令 ,娛樂(lè)性和互動(dòng)性更強(qiáng) . 該小車(chē)各部分采用模塊化設(shè)計(jì)，各個(gè)模塊之間獨(dú)立性強(qiáng)?？刂撇糠植捎每删幊涛⑻幚砜奁?，可以在不增加系統(tǒng)硬件的情況下方便地對(duì)系統(tǒng)進(jìn)行二次開(kāi)發(fā)。本文對(duì)一輛小車(chē)進(jìn)行了實(shí)驗(yàn)，實(shí)驗(yàn)結(jié)果表明，語(yǔ)音識(shí)別系統(tǒng)在低噪聲環(huán)境中識(shí)別率很高，在噪聲水平較高的場(chǎng)合，識(shí)別率有所下降。小 車(chē)反應(yīng)靈敏。 關(guān)鍵詞：語(yǔ)音識(shí)別 單片機(jī) 智能小車(chē) 電機(jī)驅(qū)動(dòng) 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(yǔ)音識(shí)別模塊 .................................................................................................. 6 電機(jī)驅(qū)動(dòng)模塊 ................................................................................................ 10 紅外檢測(cè)模塊 ................................................................................................ 11 鍵盤(pán)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(yǔ)音訓(xùn)練程序 ................................................................................................. 20 鍵盤(pán)掃描程序 ................................................................................................ 21 電機(jī)驅(qū)動(dòng)程序 ................................................................................................. 22 延時(shí)程序 ........................................................................................................ 24 程序清單： ................................................................................................
